Incidence density mortality rate among HIV-positive children on antiretroviral therapy in Ethiopia: a systematic review and meta-analysis. BMC Public Health 2024; 24:2061. [PMID: 39085806 PMCID: PMC11290179 DOI: 10.1186/s12889-024-19579-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 07/24/2024] [Indexed: 08/02/2024] Open
Abstract
BACKGROUND Human Immunodeficiency Virus (HIV) continues to be the major cause of childhood deaths, particularly in the sub-Saharan African region. In Ethiopia, though several primary studies have been conducted on the incidence of HIV-related child mortality, the pooled incidence density mortality rate among HIV-positive children is unknown. Therefore, this systematic review and meta-analysis aimed to estimate the pooled incidence density mortality rate among HIV-positive children and identify its associated factors in Ethiopia. METHODS We browsed PubMed, HINARI, Science Direct, Google Scholar, African Journals Online, and cross-references using different search terms to identify articles. Quality appraisal was done using the Joanna Briggs Institute checklist. Meta-package was used to estimate the pooled incidence of mortality and hazard ratio (HR) of predictors. Heterogeneity was tested using the I-square statistics. Publication bias was tested using a funnel plot visual inspection and Egger's test. Data was presented using forest plots and tables. The random effect model was used to compute the pooled estimate. RESULTS The overall pooled incidence density mortality rate among HIV-positive children was 2.52 (95% CI: 1.82, 3.47) per 100 child years. Advanced HIV disease (hazard ratio (HR): 3.45, 95% CI (Confidence Interval): 2.64, 4.51), tuberculosis co-infection (HR: 3.19, 95% CI: 2.08, 4.88), stunting (3.22, 95% CI: 2.46, 4.22), underweight (HR: 2.71, 95% CI: 1.72, 4.26), wasting (HR: 4.14, 95% CI: 2.27, 7.58), didn't receive Isoniazid preventive therapy (HR: 3.33, 95% CI: 2.22, 4.99), anemia (HR: 3.03, 95% CI: 2.52, 3.64), fair or poor antiretroviral therapy adherence (HR: 4.14, 95% CI: 3.28, 5.28) and didn't receive cotrimoxazole preventive therapy (HR: 3.82, 95% CI: 2.49, 5.86) were factors associated with a higher hazard of HIV related child mortality. CONCLUSIONS The overall pooled incidence density mortality rate among HIV-positive children was high in Ethiopia as compared to the national strategy target. Therefore, counseling on antiretroviral therapy adherence should be strengthened. Regular monitoring of hemoglobin levels and assessment of nutritional status should be done for all children living with HIV. Moreover, healthcare professionals should follow the national HIV treatment guidelines and provide cotrimoxazole preventive therapy and Isoniazid preventive therapy up on the guidelines for children living with HIV.

Abstract
BACKGROUND An estimated 21,000 children 0-14 years of age were living with HIV in Côte d'Ivoire in 2020, of whom only 49% have been diagnosed and are receiving antiretroviral therapy (ART). Retention in HIV care and treatment is key to optimize clinical outcomes. We evaluated pediatric retention in select care and treatment centers (CTCs) in Côte d'Ivoire. METHODS We retrospectively reviewed medical records using 2-stage cluster sampling for children under 15 years initiated on ART between 2012 and 2016. Kaplan-Meier time-to-event analysis was done to estimate cumulative attrition rates per total person-years of observation. Cox proportional hazard regression was performed to identify factors associated with attrition. RESULTS A total of 1198 patient records from 33 CTCs were reviewed. Retention at 12, 24, 36, 48 and 60 months after ART initiation was 91%, 84%, 74%, 72% and 70%, respectively. A total of 309 attrition events occurred over 3169 person-years of follow-up [266 children were lost to follow-up (LTFU), 29 transferred to another facility and 14 died]. LTFU determinants included attending a "public-private" CTC [adjusted hazard ratio (aHR) 6.05; 95% confidence interval (CI): 4.23-8.65], receiving care at a CTC without an on-site laboratory (aHR: 4.01; 95% CI: 1.70-9.46) or attending a CTC without an electronic medical record (EMR) system (aHR: 2.22; 95% CI: 1.59-3.12). CONCLUSIONS In Cote d'Ivoire, patients attending a CTC that is public-private, does not have on-site laboratory or EMR system were likely to be LTFU. Decentralization of laboratory services and scaling use of EMR systems could help to improve pediatric retention.

Factors Associated with Retention of HIV Patients on Antiretroviral Therapy in Care: Evidence from Outpatient Clinics in Two Provinces of the Democratic Republic of the Congo (DRC). Trop Med Infect Dis 2022; 7:tropicalmed7090229. [PMID: 36136640 PMCID: PMC9504336 DOI: 10.3390/tropicalmed7090229] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 08/25/2022] [Accepted: 08/26/2022] [Indexed: 12/02/2022] Open
Abstract
Interruptions in the continuum of care for HIV can inadvertently increase a patient’s risk of poor health outcomes such as uncontrolled viral load and a greater likelihood of developing drug resistance. Retention of people living with HIV (PLHIV) in care and determinants of attrition, such as adherence to treatment, are among the most critical links strengthening the continuum of care, reducing the risk of treatment failure, and assuring viral load suppression. Objective: To analyze the variation in, and factors associated with, retention of patients enrolled in HIV services at outpatient clinics in the provinces of Kinshasa and Haut-Katanga, Democratic Republic of the Congo (DRC). Methods: Data for the last visit of 51,286 patients enrolled in Centers for Disease Control (CDC)-supported outpatient HIV clinics in 18 health zones in Haut-Katanga and Kinshasa, DRC were extracted in June 2020. Chi-square tests and multivariable logistic regressions were performed. Results: The results showed a retention rate of 78.2%. Most patients were classified to be at WHO clinical stage 1 (42.1%), the asymptomatic stage, and only 3.2% were at stage 4, the severest stage of AIDS. Odds of retention were significantly higher for patients at WHO clinical stage 1 compared to stage 4 (adjusted odds ratio (AOR), 1.325; confidence interval (CI), 1.13−1.55), women as opposed to men (AOR, 2.00; CI, 1.63−2.44), and women who were not pregnant (vs. pregnant women) at the start of antiretroviral therapy (ART) (AOR, 2.80; CI, 2.04−3.85). Odds of retention were significantly lower for patients who received a one-month supply rather than multiple months (AOR, 0.22; CI, 0.20−0.23), and for patients in urban health zones (AOR, 0.75; CI, 0.59−0.94) rather than rural. Compared to patients 55 years of age or older, the odds of retention were significantly lower for patients younger than 15 (AOR, 0.35; CI, 0.30−0.42), and those aged 15 and <55 (AOR, 0.75; CI, 0.68−0.82). Conclusions: Significant variations exist in the retention of patients in HIV care by patient characteristics. There is evidence of strong associations of many patient characteristics with retention in care, including clinical, demographic, and other contextual variables that may be beneficial for improvements in HIV services in DRC.

Abstract
Expanded access to HIV treatment services has improved outcomes for children and adolescents living with HIV in Kenya. Minimal data are available on these outcomes. We describe temporal trends in outcomes for children and adolescents initiating antiretroviral therapy (ART) from 2004 to 2014 at sites supported by Centre for Health Solutions—Kenya, in central Kenya. We retrospectively analyzed data from children 0–9 years of age (n = 3,519) and adolescents 10–19 years of age (n = 1,663) living with HIV, who newly initiated ART at 47 health facilities in central Kenya. Year cohorts were analyzed from the Comprehensive Patient Application Database (CPAD) and International Quality Care (IQCare) electronic medical databases, including temporal trends in outcomes and associated factors using multivariable competing risk regression analysis. There were more girls (2,453 [52.7%]) than boys, with most enrolled at World Health Organization (WHO) stage II (1,813 [37.7%]) or III disease (1,694 [35.1%]). Most of the children and adolescents (4,431 [96.4%]) did not have tuberculosis (TB) symptoms. Cumulative lost to follow-up (LTFU) incidence at 6, 12, 24, and 36 months were 5.0%, 9.9%, 22.9%, and 33.1%, respectively. Cumulative mortality incidence at 6, 12, 24, and 36 months were 0.7%, 1.0%, 1.2%, and 1.5%, respectively. The incidence of LTFU was higher among female children and adolescents, those initiated on tenofovir-based regimens, and those with presumptive TB symptoms. Mortality risk was higher among those with WHO stage III or IV disease, and children and adolescents on TB treatment or who had presumptive TB. Enrollment occurred at a young age and pediatric-friendly ART regimens were initiated at earlier WHO stages implying effective early infant diagnosis and treatment for all strategies, resulting in improved treatment outcomes. The higher retention rates in recent years as well as the lower retention after many years of follow-up underscore the importance of implementing longitudinal follow-up strategies targeting this population.

Abstract
Background HIV infection has been associated with a non-erosive inflammatory arthritis in children, although few published reports exist. This study describes the clinical, laboratory and imaging features of this noncommunicable disease in a series of HIV-infected children in South Africa. Methods A database search was conducted to identify HIV-infected children enrolled in a Paediatric Rheumatology service in Cape Town, South Africa between 1 January 2010 and 31 December 2020. Retrospective data were collected from individuals classified with HIV arthropathy, based on a predefined checklist. Demographic, clinical, laboratory, sonographic, therapeutic, and outcomes data were extracted by chart review. Descriptive statistical analysis was performed using R (v4.0.3). Results Eleven cases of HIV arthropathy were included in the analysis. Cases predominantly presented in older boys with low CD4+ counts. Median age at arthritis onset was 10.3 years (IQR 6.9 – 11.6) and the male-female ratio was 3.0. The median absolute CD4+ count was 389 cells/uL (IQR 322 – 449). The clinical presentation was variable, with both oligoarthritis and polyarthritis being common. Elevated acute phase reactants were the most consistent laboratory feature, with a median ESR of 126 mL/h (IQR 67 – 136) and median CRP of 36 mg/L (IQR 25 – 68). Ultrasonography demonstrated joint effusions and synovial hypertrophy. Response to therapy was slower than has generally been described in adults, with almost all cases requiring more than one immunosuppressive agent. Five children were discharged in established remission after discontinuing immunotherapy, however outcomes data were incomplete for the remaining six cases. Conclusions In this case series, HIV arthropathy was associated with advanced immunosuppression. Therapeutic modalities included immunomodulators and antiretroviral therapy, which consistently induced disease remission although data were limited by a high rate of attrition. Prospective studies are needed to define and understand this HIV-associated noncommunicable disease.

Abstract
Early treatment with combination antiretroviral therapy (cART) has improved survival of children perinatally infected with HIV into adolescence. This population is at risk of long term complications related to HIV infection, particularly chronic respiratory disease. Limited data on chest imaging findings in HIV-infected adolescents, suggest that the predominant disease is of small and large airways: predominantly bronchiolitis obliterans or bronchiectasis. Single cases of emphysema have been reported. Lung fibrosis, lymphocytic interstitial pneumonitis, post tuberculous apical fibrocystic changes and malignancies do not feature in this population. Chest radiograph (CXR) is easily accessible and widely used, especially in resource limited settings, such as sub Saharan Africa, where the greatest burden of HIV disease occurs. Lung ultrasound has been described for the diagnosis of pneumonia in children, pulmonary oedema and interstitial lung disease [1-3]. The use of this modality in chronic respiratory disease in adolescents where the predominant finding is small airway disease and bronchiectasis has however not been described. CXR is useful to evaluate structural/post infective changes, parenchymal opacification and nodules, hyperinflation or extensive bronchiectasis. CXR however, is inadequate for diagnosing small airway disease, for which high resolution computed tomography (HRCT) is the modality of choice. Where available, low dose HRCT should be used early in the course of symptomatic disease in adolescents and for follow up in children who are non responsive to treatment or clinically deteriorating. This article provides a pictorial review of the spectrum of CXR and HRCT imaging findings of chronic pulmonary disease in perinatally HIV-infected adolescents on cART and guidelines for imaging.

Abstract
Introduction Evaluating outcomes of paediatric patients with HIV provides crucial data for clinicians and policymakers. We analysed mortality and clinical events rates among children, adolescents, and youth with perinatally acquired HIV (PHIV) aged 0 to 24 years stratified by time‐varying age and CD4, before and after antiretroviral therapy (ART), in the paediatric IeDEA multiregional collaboration (East, West, Central and Southern Africa, Asia‐Pacific, and Central/South America and the Caribbean). Methods ART‐naïve children with HIV enrolled before age 10 (proxy for perinatal infection) at IeDEA sites between 2004 and 2016, with ≥1 CD4 measurement during follow‐up were included. We estimated incidence rates (IR) and 95% confidence intervals (95% CI) of mortality and first occurrence of WHO‐4 and WHO‐3 events, excluding tuberculosis, during person‐years (PY) spent within different age (<2, 2 to 4, 5 to 9, 10 to 14, 15 to 19, 20 to 24) and CD4 (percent when <5 years [<15%, 15% to 24%, ≥25%]; count when ≥5 years [<200, 200 to 499, ≥500 cells/µL]) strata. We used linear mixed models to predict CD4 evolution, with trends modelled by region. Results In the pre‐ART period, 49 137 participants contributed 51 966 PY of follow‐up (median enrolment age: 3.9 years). The overall pre‐ART IRs were 2.8/100 PY (95% CI: 2.7 to 2.9) for mortality, 3.3/100 PY (95% CI: 3.0 to 3.5) for first occurrence of a WHO‐4 event, and 7.0/100 PY (95% CI: 6.7 to 7.4) for first occurrence of a WHO‐3 event. Lower CD4 and younger age strata were associated with increased rates of both mortality and first occurrence of a clinical event. In the post‐ART period, 52 147 PHIVY contributed 207 945 PY (ART initiation median age: 4.5 years). Overall mortality IR was 1.4/100 PY (95% CI: 1.4 to 1.5) and higher in low CD4 strata; patients at each end of the age spectrum (<2 and >19) had increased mortality post‐ART. IRs for first occurrence of WHO‐4 and WHO‐3 events were 1.3/100 PY (95% CI: 1.2 to 1.4) and 2.1/100 PY (95% CI: 2.0 to 2.2) respectively. These were also associated with lower CD4 and younger age strata. Conclusions Mortality and incidence of clinical events were highest in both younger (<2 years) and older (>19 years) youth with PHIV. Scaling‐up services for <2 years (early access to HIV diagnosis and care) and >19 years (adolescent‐ and youth‐focused health services) is critical to improve outcomes among PHIVY.

Abstract
BACKGROUND It is a global challenge to enrol and retain paediatric patients in HIV/AIDS care. Attrition causes preventable transmission, stoppable morbidity and death, undesirable treatment outcomes, increased cost of care and drug resistance. Thus, this study intended to investigate the incidence and predictors of attrition among children receiving antiretroviral treatment (ART). METHOD A retrospective follow-up study was conducted among children <15 years who had ART follow-up in Gedeo public hospitals. After collection, data were entered into Epi-data V.4.6, then exported to and analysed using STATA V.14. Data were described using the Kaplan-Meier statistics, life table and general descriptive statistics. The analysis was computed using the Cox proportional hazard regression model. Covariates having <0.25 p values in the univariate analysis (such as developmental stage, nutritional status, haemoglobin level, adherence, etc) were fitted to multivariable analysis. Finally, statistical significance was declared at a p value of <0.05. RESULTS An overall 254 child charts were analysed. At the end of follow-up, attrition from ART care was 36.2% (92 of 254), of which 70 (76.1%) were lost to follow-up, and 22 (23.9%) children died. About 8145.33 child-months of observations were recorded with an incidence attrition rate of 11.3 per 1000 child-months (95% CI: 9.2 to 13.9), whereas the median survival time was 68.73 months. Decreased haemoglobin level (<10 g/dl) (adjusted HR (AHR)=3.1; 95% CI: 1.4 to 6.9), delayed developmental milestones (AHR=3.6; 95% CI: 1.2 to 10.7), underweight at baseline (AHR=5.9; 95% CI: 1.6 to 21.7), baseline CD4 count ≤200 (AHR=4.4; 95% CI: 1.6 to 12.2), and poor or fair ART adherence (AHR=3.5; 95% CI: 1.5 to 7.9) were significantly associated with attrition. CONCLUSION AND RECOMMENDATION Retention to ART care is challenging in the paediatrics population, with such a high attrition rate. Immune suppression, anaemia, underweight, delayed developmental milestones and ART non-adherence were independent predictors of attrition to ART care. Hence, it is crucial to detect and control the identified predictors promptly. Serious adherence support and strengthened nutritional provision with monitoring strategies are also essential.

Jacobs TG, Svensson EM, Musiime V, Rojo P, Dooley KE, McIlleron H, Aarnoutse RE, Burger DM, Turkova A, Colbers A. Pharmacokinetics of antiretroviral and tuberculosis drugs in children with HIV/TB co-infection: a systematic review. J Antimicrob Chemother 2020; 75:3433-3457. [PMID: 32785712 PMCID: PMC7662174 DOI: 10.1093/jac/dkaa328] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 06/29/2020] [Indexed: 12/18/2022] Open
Abstract
INTRODUCTION Management of concomitant use of ART and TB drugs is difficult because of the many drug-drug interactions (DDIs) between the medications. This systematic review provides an overview of the current state of knowledge about the pharmacokinetics (PK) of ART and TB treatment in children with HIV/TB co-infection, and identifies knowledge gaps. METHODS We searched Embase and PubMed, and systematically searched abstract books of relevant conferences, following PRISMA guidelines. Studies not reporting PK parameters, investigating medicines that are not available any longer or not including children with HIV/TB co-infection were excluded. All studies were assessed for quality. RESULTS In total, 47 studies met the inclusion criteria. No dose adjustments are necessary for efavirenz during concomitant first-line TB treatment use, but intersubject PK variability was high, especially in children <3 years of age. Super-boosted lopinavir/ritonavir (ratio 1:1) resulted in adequate lopinavir trough concentrations during rifampicin co-administration. Double-dosed raltegravir can be given with rifampicin in children >4 weeks old as well as twice-daily dolutegravir (instead of once daily) in children older than 6 years. Exposure to some TB drugs (ethambutol and rifampicin) was reduced in the setting of HIV infection, regardless of ART use. Only limited PK data of second-line TB drugs with ART in children who are HIV infected have been published. CONCLUSIONS Whereas integrase inhibitors seem favourable in older children, there are limited options for ART in young children (<3 years) receiving rifampicin-based TB therapy. The PK of TB drugs in HIV-infected children warrants further research.

Feasibility and acceptability of implementing early infant diagnosis of HIV in Papua New Guinea at the point of care: a qualitative exploration of health worker and key informant perspectives. BMJ Open 2020; 10:e043679. [PMID: 33444219 PMCID: PMC7678362 DOI: 10.1136/bmjopen-2020-043679] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 10/27/2020] [Accepted: 10/28/2020] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION Early infant diagnosis (EID) of HIV and timely initiation of antiretroviral therapy can significantly reduce morbidity and mortality among HIV-positive infants. Access to EID is limited in many low-income and middle-income settings, particularly those in which standard care involves dried blood spots (DBS) sent to centralised laboratories, such as in Papua New Guinea (PNG). We conducted a qualitative exploration of the feasibility and acceptability of implementing a point-of-care (POC) EID test (Xpert HIV-1 Qualitative assay) among health workers and key stakeholders working within the prevention of mother-to-child transmission of HIV (PMTCT) programme in PNG. METHODS This qualitative substudy was conducted as part of a pragmatic trial to investigate the effectiveness of the Xpert HIV-1 Qualitative test for EID in PNG and Myanmar. Semistructured interviews were undertaken with 5 health workers and 13 key informants to explore current services, experiences of EID testing, perspectives on the Xpert test and the feasibility of integrating and scaling up POC EID in PNG. Coding was undertaken using inductive and deductive approaches, drawing on existing acceptability and feasibility frameworks. RESULTS Health workers and key informants (N=18) felt EID at POC was feasible to implement and beneficial to HIV-exposed infants and their families, staff and the PMTCT programme more broadly. All study participants highlighted starting HIV-positive infants on treatment immediately as the main advantage of POC EID compared with standard care DBS testing. Health workers identified insufficient resources to follow up infants and caregivers and space constraints in hospitals as barriers to implementation. Participants emphasised the importance of adequate human resources, ongoing training and support, appropriate coordination and a sustainable supply of consumables to ensure effective scale-up of the test throughout PNG. CONCLUSIONS Implementation of POC EID in a low HIV prevalence setting such as PNG is likely to be both feasible and beneficial with careful planning and adequate resources.

[Access to the management of HIV infected children: Overview of the healthcare supply in Cameroon in 2014]. Rev Epidemiol Sante Publique 2020; 68:243-251. [PMID: 32631665 DOI: 10.1016/j.respe.2020.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 03/20/2020] [Accepted: 05/19/2020] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND In Cameroon in 2012, the proportion (15%) of children eligible for antiretroviral treatment (ART) was one of the lowest among the 21 Global Fund priority countries. The objective of this study was to carry out a situational analysis of the existing care offer for pediatric HIV in Cameroon. METHODS A descriptive cross-sectional study was conducted over a 4-month period (April to August 2014) in 12 healthcare facilities in 7 regions of Cameroon selected by systematic sampling. The data were collected in a self-administered questionnaire filled out by the caregiving and administrative personnel included in the study. RESULTS All in all, 142 persons in charge of pediatric HIV treatment were included in the study, of whom 115 were working at the operational level: 59 (51.2%) health personnel, 44 (38.3%) community agents and 12 (10.4%) department heads; the other 27 exercised responsibilities at the regional (19) and the local (8) levels. An overwhelming majority of the caregivers involved in pediatric VIH treatment were nurses, a factor necessitating the delegation of medical tasks institutionalized in Cameroon. Few standardized nationwide documents take into account these treatment modalities. Inadequate dissemination of the documents at all levels of the healthcare pyramid may justify the non-compliance with the care protocols that has been observed in the training programs dedicated to the subject. CONCLUSION The updating and large-scale dissemination of standardized nationwide documents taking into account the specificities of HIV-infected children are required to improve implementation at the operational level of the Cameroonian healthcare system of the existing guidelines for pediatric HIV treatment.

Abstract
BACKGROUND A negative status following confirmatory Early Infant Diagnosis (EID) is the desired pediatric outcome of prevention of Mother to Child Transmission (PMTCT) programs. EID impacts epidemic control by confirming non-infected HIV-exposed infants (HEIs) and prompting timely initiation of ART in HIV-infected babies which improves treatment outcomes. OBJECTIVES We explored factors associated with EID outcomes among HEI in North-Central Nigeria. METHOD This is a cross-sectional study using EID data of PMTCT-enrollees matched with results of HEI's dried blood samples (DBS), processed for DNA-PCR from January 2015 through July 2017. Statistical analyses were done using SPSS version 20.0 to generate frequencies and examine associations, including binomial logistic regression with p < 0.05 being statistically significant. RESULTS Of 14,448 HEI in this analysis, 51.8% were female and 95% (n = 12,801) were breastfed. The median age of the infants at sample collection was 8 weeks (IQR 6-20), compared to HEI tested after 20 weeks of age, those tested earlier had significantly greater odds of a negative HIV result (≤ 6 weeks: OR = 3.8; 6-8 weeks: OR = 2.1; 8-20 weeks: OR = 1.5) with evidence of a significant linear trend (p < 0.001). Similarly, HEI whose mothers received combination antiretroviral therapy (cART) before (OR = 11.8) or during the index pregnancy (OR = 8.4) had significantly higher odds as compared to those whose mothers did not receive cART. In addition, HEI not breastfed had greater odds of negative HIV result as compared to those breastfed (OR = 1.9). CONCLUSIONS cART prior to and during pregnancy, earlier age of HEI at EID testing and alternative feeding other than breastfeeding were associated with an increased likelihood of being HIV-negative on EID. Therefore, strategies to scale-up PMTCT services are needed to mitigate the burden of HIV among children.

Abstract
Background: To accelerate access to pediatric HIV care in Cameroon, operational challenges in implementing HIV pediatric care need to be identified. The aim of this study was to assess the knowledge, attitudes, and practices of health care workers regarding pediatric HIV infection in Cameroon. Methods: A descriptive cross-sectional study was conducted over a 4-month period (April to August 2014) in 12 health facilities in 7 regions of Cameroon selected using systematic random sampling. Data were collected from interviews with health care providers and managers using standardized self-administered questionnaires and stored in the ACCESS software. Results: In total, 103 health care providers were included in this study, of which 59 (57.3%) were health workers and 44 (42.7%) community agents. Most of the health workers in charge of HIV pediatric care were nurses, requiring effective medical task shifting that was institutionalized in Cameroon. The knowledge of health care providers in relation to pediatric HIV care was acceptable. Indications for prescription of test for early infant diagnosis were known (96.1%), but their attitudes and practices regarding initiating antiretroviral therapy (ART) in infants less than 2 years (5.2%) and first-line ART protocols (25.4%) were insufficient, due to little information about standard procedures. Conclusion: Capacity building of health care providers and large-scale dissemination of normative national documents are imperative to improve HIV pediatric care in the health care facilities.

Abstract
Introduction African studies have reported high rates of loss to follow up (LTFU) among children in HIV care and treatment centres. Factors associated with LTFU may vary across populations. Few studies have been conducted among HIV infected children in care in rural areas of Kenya. Methods this involved children aged less than 15 years on follow up at Kangundo Level 4 Hospital HIV clinic from January 2010 to December 2015. We obtained sociodemographic and clinical information from patient files and electronic databases. Univariate and multivariate regression analyses were conducted to identify factors predictive of LTFU. Results a total of 261 HIV-infected children were followed up. The mean age was 10.0 years (IQR, 7-13) and median CD4 count of 582cells/ul (IQR 314-984). By December 2015, 171 children (65.5%) remained in active care, 32 (12.3%) transferred out, 13 (5%) died, while 45 (17.2%) were classified as LTFU. Out of the 45 children presumed as LTFU, we traced 44 out of the 45 children (98%) and found that their actual current status was as follows: 33 of the 44 children (75.0%) had dropped out of care (true LTFU). Factors strongly predictive of LTFU included low caregiver level of education (HR 2.3, 1.9-3.9, P = 0.001), WHO stage I and II at enrolment (HR 1.6, 1.4-2.1, P = 0.05). Conclusion LTFU of HIV infected children was common with an incidence of 32.9 per 1000 child years and occurred early in treatment and risk factors included poverty, low caregiver education, male child and early HIV disease stage.

Abstract
Background Despite substantial improvements in accessibility of Anti-Retroviral Treatment (ART), death of children on ART remains a prevailing challenge in sub-Saharan African (SSA) countries. However, the pooled magnitude of mortality at different ART follow-up periods remains unknown for the region. We estimated the pooled proportion of all-cause mortality for pediatric patients receiving first-line ART at 3, 6, 12, and 24 months follow-up period in SSA. Methods We searched for relevant articles published between January 2014 and June 2018 on PubMed, Hinari and Google scholar databases. We searched for additional articles from reference lists and 2014–2018 abstracts archived by the Conference on Retroviruses and Opportunistic Infections (CROI) and the International AIDS Society Conference on HIV Science (IAS). Results We reviewed 29 articles reporting mortality among pediatric ART patients at different follow-up periods in countries from 2001 to 2016. Among the 51,619 pediatric ART patients in these cohorts, studies reported 4061 (7.9%) all-cause cumulative death. The cumulative pooled proportion of mortality at 3, 6, 12 and 24 months of ART were 3% (95% CI: 3.0–4.0), 5% (95% CI: 4.0–6.0), 6% (95% CI: 5.0–7.0) and 7% (95% CI: 6.0–8.0), respectively. Conclusions In SSA, significant proportion of mortality among children occurs in the first 3–6 months of ART initiation. Western Africa has a little higher estimate of mortality among pediatric ART patients at 6 and 12 months of follow-up. Strategies to prevent early mortality including thorough screening and management of opportunistic infections before ART initiation are needed.

Abstract
OBJECTIVES To estimate the magnitude of mortality and loss to follow-up and describe predictors of mortality among HIV-infected children in Guinea-Bissau. METHODS Retrospective follow-up study among HIV-infected children under 15 years of age at the largest HIV-clinic in Guinea-Bissau from 2006-2016. A multivariate Cox proportional hazards model was used to identify predictors of mortality. RESULTS Of 525 children were included in the analysis: 371 (70.7%) with HIV-1, 17 (3.2%) with HIV-2, 25 (4.8%) with HIV-1/2, and 112 (21.3%) with HIV of unknown type. At diagnosis, the median age was 3.5 years, 44.7% met the WHO criteria for severe immunodeficiency by age based on CD4 cell count, and 59.4% were underweight. The median follow-up time was 6 months. Despite the availability of antiretroviral treatment, the mortality rate was 10.4 deaths per 100 person-years of follow-up. Within the first year of follow-up, 11.0% died, 3.1% were transferred and 38.8% were lost to follow-up, leaving 47.1% in follow-up. Severe immunodeficiency (adjusted hazard ratio (aHR) = 2.52, 95% CI: 1.22-5.21) and underweight (aHR = 3.14, 95% CI: 1.40-7.02) were independent predictors of mortality. CONCLUSIONS This study reveals a high rate of early mortality and loss to follow-up among HIV-infected children in Guinea-Bissau. Initiatives to improve patient retention are urgently needed.

Temporal Improvements in Long-term Outcome in Care Among HIV-infected Children Enrolled in Public Antiretroviral Treatment Care: An Analysis of Outcomes From 2004 to 2012 in Zimbabwe. Pediatr Infect Dis J 2018; 37:794-800.

Abstract
BACKGROUND Increasing numbers of children are requiring long-term HIV care and antiretroviral treatment (ART) in public ART programs in Africa, but temporal trends and long-term outcomes in care remain poorly understood. METHODS We analyzed outcomes in a longitudinal cohort of infants (<2 years of age) and children (2-10 years of age) enrolling in a public tertiary ART center in Zimbabwe over an 8-year period (2004-2012). RESULTS The clinic enrolled 1644 infants and children; the median age at enrollment was 39 months (interquartile range: 14-79), with a median CD4% of 17.0 (interquartile range: 11-24) in infants and 15.0 (9%-23%) in children (P = 0.0007). Among those linked to care, 33.5% dropped out of care within the first 3 months of enrollment. After implementation of revised guidelines in 2009, decentralization of care and increased access to prevention of mother to child transmission services, we observed an increase in infants (48.9%-68.3%; P < 0.0001) and children (48.9%-68.3%; P < 0.0001) remaining in care for more than 3 months. Children enrolled from 2009 were younger, had lower World Health Organization clinical stage, improved baseline CD4 counts than those who enrolled in 2004-2008. Long-term retention in care also improved with decreasing risk of loss from care at 36 months for infants enrolled from 2009 (aHR: 0.57; 95% confidence interval: 0.34-0.95; P = 0.031). ART eligibility at enrollment was a significant predictor of long-term retention in care, while delayed ART initiation after 5 years of age resulted in failure to fully reconstitute CD4 counts to age-appropriate levels despite prolonged ART. CONCLUSIONS Significant improvements have been made in engaging and retaining children in care in public ART programs in Zimbabwe. Guideline and policy changes that increase access and eligibility will likely to continue to support improvement in pediatric HIV outcomes.

Abstract
INTRODUCTION HIV-exposed infants (HEI) lost-to-follow-up (LTFU) remains a problem in sub Saharan Africa (SSA). In 2015, SSA accounted >90% of the 150,000 new infant HIV infections, with an estimated 13,000 reported in Kenya. Despite proven and effective HIV interventions, many HEI fail to benefit because of LTFU. LTFU leads to delays or no initiation of interventions, thereby contributing to significant child morbidity and mortality. Kenya did not achieve the <5% mother-to-child HIV transmission target by 2015 because of problems such as LTFU. We sought to investigate factors associated with LTFU of HEI in Kericho County, Kenya. METHODS A case-control study was conducted in June 2016 employing 1:2 frequency matching by age and hospital of birth. We recruited HEI from HEI birth cohort registers from hospitals for the months of September 2014 through February 2016. Cases were infant-mother pairs that missed their 3-month clinic appointments while controls were those that adhered to their 3-month follow-up visits. Consent was obtained from caregivers and a structured questionnaire was administered. We used chi-square and Fisher's Exact tests to compare groups, calculated odds ratios (OR) and 95% confidence intervals (CI), and performed logistic regression to identify independent risk factors. RESULTS We enrolled 44 cases and 88 controls aged ≥3 to 18 months: Cases ranged from 7.3-17.8 months old and controls from 6.8-17.2 months old. LTFU cases' caregivers were more likely than controls' caregivers to fear knowing HEI status (aOR= 12.71 [CI 3.21-50.23]), lack knowledge that HEI are followed for 18 months (aOR= 12.01 [CI 2.92-48.83]), avoid partners knowing their HEI status(OR= 11.32 [CI 2.92-44.04]), and use traditional medicine (aOR= 6.42 [CI 1.81-22.91]).Factors that were protective of LTFU included mothers knowing their pre-pregnancy HIV status (aOR= 0.23 [CI 0.05-0.71]) and having household health insurance (aOR= 0.11 [CI 0.01-0.76]). CONCLUSION Caregivers' intrinsic, interpersonal, community and health system factors remain crucial towards reducing HEI LTFU. Early HIV testing among mothers, disclosure support, health education, and partner involvement is advocated. Encouraging households to enroll in health insurance could be beneficial. Further studies on the magnitude and the reasons for use of home treatments among caregiver are recommended.

HIV care and treatment clinic performance following President's Emergency Plan for AIDS Relief-funded infrastructure improvement in Tanzania. South Afr J HIV Med 2018; 19:777. [PMID: 39449987 PMCID: PMC11500648 DOI: 10.4102/sajhivmed.v19i1.777] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Accepted: 04/17/2018] [Indexed: 10/26/2024] Open
Abstract
Purpose To assess how the infrastructure improvements supported by the US Centers for Disease Control and Prevention (CDC) and the United States President's Emergency Plan for AIDS Relief (PEPFAR) contributed to facility-level quarterly and annual new patient enrolment in HIV care and treatment and antiretroviral therapy (ART) uptake and retention in care. Methods Aggregate quarterly and annual facility-based HIV care and treatment data from the CDC-managed PEPFAR Reporting Online and Management Information System database collected between 2005 and 2012 were analysed for the 11 rural and 32 urban facilities that met the eligibility criteria. Infrastructure improvements, including both renovations and new construction, occurred on different dates for the facilities; therefore, data were adjusted such that pre- and post-infrastructure improvements were aligned and date-time was ignored. The analysis calculated the mean (95% confidence interval) number of patients per facility who were (1) newly enrolled in HIV care, (2) patients initiated on ART, (3) patients retained in care, defined as alive and on ART, and (4) reasons for attrition, defined as transferred out, lost to follow-up, deceased or stopped ART. Results The overall mean number of adult patients newly enrolled in HIV care clinics per quarter declined from 187.7 (151.4-223.9) to 135.2 (117.4-152.9) after infrastructure improvements but was not statistically significant (p = 0.20). However, the mean number of patients who were alive and remained on ART increased from 193.2 (145.3-241.1) to 273.2 (219.0-327.3) after improvements in both rural and urban facilities, although not significantly (p = 0.59). A similar picture was observed for overall paediatric enrolment and retention in care. Health facility-specific case studies show variations in new patient enrolment and retention in care between health facilities depending on the catchment area, population HIV prevalence and coverage of ART facilities. Regarding attrition, the mean number of adult patients lost to follow-up changed from 76.6 (20.8-132.3) to 139.4 (79.6-199.1) (p = 0.65) among rural facilities, while the mean number of children lost to follow-up increased significantly from 3.4 (0.5-6.3) to 8.7 (5.0-12.3) (p = 0.02) after improvements. Conclusion Patient retention in care improved in HIV care and treatment facilities with infrastructure improvements. However, the overall number of patients newly enrolled and initiated on ART declined and attrition increased in facilities after improvements.

Abstract
HIV/AIDS remains one of the leading causes of death among children under 5 years old in Swaziland. Although studies have shown that early initiation of infants and children diagnosed with HIV on antiretroviral therapy (ART) significantly reduces mortality, many children do not initiate ART until the later stages of disease. This study was designed to collect qualitative data from mothers and caregivers of HIV-positive children to identify the barriers to ART initiation. Focus group discussion (FGD) sessions were conducted in siSwati between July and September 2014 among caregivers of aged children 2-18 months in Swaziland who did or did not initiate ART between January 2011 and December 2012 after HIV DNA PCR-positive diagnosis of the infants. Denial, guilt, lack of knowledge, tuberculosis (TB)/HIV co-infection, HIV-related stigma, lack of money, and distance to clinics were reported by the participants as barriers to ART initiation. The findings further revealed that non-initiation on ART was not linked to a negative perception of the treatment. Findings suggest a need to improve sensitivity among healthcare workers as well as education and counselling services that will facilitate the ART initiation process.

Abstract
South Africa's paediatric antiretroviral therapy (ART) programme is managed using a monitoring and evaluation tool known as TIER.Net. This electronic system has several advantages over paper-based systems, allowing profiling of the paediatric ART programme over time. We analysed anonymized TIER.Net data for HIV-infected children aged <15 years who had initiated ART in a rural district of South Africa between 2005 and 2014. We performed Kaplan–Meier survival analysis to assess outcomes over time. Records of 5461 children were available for analysis; 3593 (66%) children were retained in care. Losses from the programme were higher in children initiated on treatment in more recent years (P < 0·0001) and in children aged ≤1 year at treatment initiation (P < 0·0001). For children aged <3 years, abacavir was associated with a significantly higher rate of loss from the programme compared to stavudine (hazard ratio 1·9, P < 0·001). Viral load was suppressed in 48–52% of the cohort, with no significant change over the years (P = 0·398). Analysis of TIER.Net data over time provides enhanced insights into the performance of the paediatric ART programme and highlights interventions to improve programme performance.

Retention of HIV-Infected Children in the First 12 Months of Anti-Retroviral Therapy and Predictors of Attrition in Resource Limited Settings: A Systematic Review. PLoS One 2016; 11:e0156506.

Abstract
Current UNAIDS goals aimed to end the AIDS epidemic set out to ensure that 90% of all people living with HIV know their status, 90% initiate and continue life-long anti-retroviral therapy (ART), and 90% achieve viral load suppression. In 2014 there were an estimated 2.6 million children under 15 years of age living with HIV, of which only one-third were receiving ART. Little literature exists describing retention of HIV-infected children in the first year on ART. We conducted a systematic search for English language publications reporting on retention of children with median age at ART initiation less than ten years in resource limited settings. The proportion of children retained in care on ART and predictors of attrition were identified. Twelve studies documented retention at one year ranging from 71–95% amongst 31877 African children. Among the 5558 children not retained, 4082 (73%) were reported as lost to follow up (LFU) and 1476 (27%) were confirmed to have died. No studies confirmed the outcomes of children LFU. Predictors of attrition included younger age, shorter duration of time on ART, and severe immunosuppression. In conclusion, significant attrition occurs in children in the first 12 months after ART initiation, the majority attributed to LFU, although true outcomes of children labeled as LFU are unknown. Focused efforts to ensure retention and minimize early mortality are needed as universal ART for children is scaled up.

Abstract
OBJECTIVE To identify risk factors for loss to follow-up (LTFU) in an HIV-infected pediatric population in Dar es Salaam, Tanzania, between 2004 and 2011. DESIGN Longitudinal analysis of 6236 HIV-infected children. METHODS We conducted a prospective cohort study of 6236 pediatric patients enrolled in care and treatment in Dar es Salaam from October 2004 to September 2011. LTFU was defined as missing a clinic visit for >90 days for patients on ART and for >180 days for patients in care and monitoring. The relationship of baseline and time-varying characteristics to the risk of LTFU was examined using a Cox proportional hazards model. RESULTS A total of 2130 children (34%) were LTFU over a median follow-up of 16.7 months (interquartile range, 3.4-36.9). Factors independently associated with a higher risk of LTFU were age ≤2 years (relative risk [RR] = 1.59, 95% CI: 1.40 to 1.80), diarrhea at enrollment (RR = 1.20, 95% CI: 1.03 to 1.41), a low mid-upper arm circumference for age (RR = 1.20, CI: 1.05 to 1.37), eating protein-rich foods ≤3 times a week (RR = 1.39, 95% CI: 1.05 to 1.90), taking cotrimoxazole (RR = 1.39, 95% CI: 1.06 to 1.81), initiating onto antiretrovirals (RR = 1.37, 95% CI: 1.17 to 1.61), receiving treatment at a hospital instead of a local facility (RR = 1.39, 95% CI: 1.06 to 1.41), and starting treatment in 2006 or later (RR = 1.10, 95% CI: 1.04 to 1.16). CONCLUSIONS Health workers should be aware of pediatric patients who are at a greatest risk of LTFU, such as younger and undernourished patients, so that they can proactively counsel families about the importance of visit adherence. Findings support decentralization of HIV care to local facilities as opposed to hospitals.

Outcomes of prevention of mother to child transmission of the human immunodeficiency virus-1 in rural Kenya--a cohort study. BMC Public Health 2015; 15:1008. [PMID: 26433396 PMCID: PMC4592570 DOI: 10.1186/s12889-015-2355-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2015] [Accepted: 09/25/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Success in prevention of mother-to-child transmission (PMTCT) raises the prospect of eliminating pediatric HIV infection. To achieve global elimination, however, strategies are needed to strengthen PMTCT interventions. This study aimed to determine PMTCT outcomes and identify challenges facing its successful implementation in a rural setting in Kenya. METHODS A retrospective cohort design was used. Routine demographic and clinical data for infants and mothers enrolling for PMTCT care at a rural hospital in Kenya were analysed. Cox and logistic regression were used to determine factors associated with retention and vertical transmission respectively. RESULTS Between 2006 and 2012, 1338 infants were enrolled and followed up for PMTCT care with earlier age of enrollment and improved retention observed over time. Mother to child transmission of HIV declined from 19.4 % in 2006 to 8.9 % in 2012 (non-parametric test for trend p = 0.024). From 2009 to 2012, enrolling for care after 6 months of age, adjusted Odds Ratio [aOR]: 23.3 [95 % confidence interval (CI): 8.3-65.4], presence of malnutrition ([aOR]: 2.3 [95 % CI: 1.1-5.2]) and lack of maternal use of highly active antiretroviral therapy (HAART) (aOR: 6.5 [95 % CI: 1.4-29.4]) was associated with increased risk of HIV infection. Infant's older age at enrollment, malnutrition and maternal HAART status, were also associated with drop out from care. Infants who were not actively followed up were more likely to drop out from care (adjusted Hazard Ratio: 6.6 [95 % CI: 2.9-14.6]). DISCUSSION We report a temporal increase in the proportion of infants enrolling for PMTCT care before 3 months of age, improved retention in PMTCT and a significant reduction in the proportion of infants enrolled who became HIV-infected, emphasizing the benefits of PMTCT. CONCLUSION A simple set of risk factors at enrollment can identify mother-infant pairs most at risk of infection or drop out for targeted intervention.

Abstract
BACKGROUND There are limited published data on the outcomes of infants starting antiretroviral therapy (ART) in routine care in Southern Africa. This study aimed to examine the baseline characteristics and outcomes of infants initiating ART. METHODS We analyzed prospectively collected cohort data from routine ART initiation in infants from 11 cohorts contributing to the International Epidemiologic Database to Evaluate AIDS in Southern Africa. We included ART-naive HIV-infected infants aged <12 months initiating ≥3 antiretroviral drugs between 2004 and 2012. Kaplan-Meier estimates were calculated for mortality, loss to follow-up (LTFU), transfer out, and virological suppression. We used Cox proportional hazard models stratified by cohort to determine baseline characteristics associated with outcomes mortality and virological suppression. RESULTS The median (interquartile range) age at ART initiation of 4945 infants was 5.9 months (3.7-8.7) with follow-up of 11.2 months (2.8-20.0). At ART initiation, 77% had WHO clinical stage 3 or 4 disease and 87% were severely immunosuppressed. Three-year mortality probability was 16% and LTFU 29%. Severe immunosuppression, WHO stage 3 or 4, anemia, being severely underweight, and initiation of treatment before 2010 were associated with higher mortality. At 12 months after ART initiation, 17% of infants were severely immunosuppressed and the probability of attaining virological suppression was 56%. CONCLUSIONS Most infants initiating ART in Southern Africa had severe disease with high probability of LTFU and mortality on ART. Although the majority of infants remaining in care showed immune recovery and virological suppression, these responses were suboptimal.

Abstract
Background Retaining patients with HIV infection in care is still a major challenge in sub- Saharan Africa, particularly in the Democratic Republic of Congo (DRC) where the antiretroviral treatment (ART) coverage is low. Monitoring retention is an important tool for evaluating the quality of care. Methods and Findings A review of medical records of HIV -infected children was performed in three health facilities in the DRC: the Amo-Congo Health center, the Monkole Clinic in Kinshasa, and the HEAL Africa Clinic in Goma. Medical records of 720 children were included. Kaplan Meier curves were constructed with the probability of retention at 6 months, 1 year, 2 years and 3 years. Retention rates were: 88.2% (95% CI: 85.1%–90.8%) at 6 months; 85% (95% CI: 81.5%–87.6%) at one year; 79.4% (95%CI: 75.5%–82.8%) at two years and 74.7% (95% CI: 70.5%–78.5%) at 3 years. The retention varied across study sites: 88.2%, 66.6% and 92.5% at 6 months; 84%, 59% and 90% at 12 months and 75.7%, 56.3% and 85.8% at 24 months respectively for Amo-Congo/Kasavubu, Monkole facility and HEAL Africa. After multivariable Cox regression four variables remained independently associated with attrition: study site, CD4 cell count <350 cells/µL, children younger than 2 years and children whose caregivers were member of an independent church. Conclusions Attrition remains a challenge for pediatric HIV positive patients in ART programs in DRC. In addition, the low coverage of pediatric treatment exacerbates the situation of pediatric HIV/AIDS.

Factors associated with non-adherence to scheduled medical follow-up appointments among Cameroonian children requiring HIV care: a case-control analysis of the usual-care group in the MORE CARE trial. Infect Dis Poverty 2014; 3:44. [PMID: 25671122 PMCID: PMC4322435 DOI: 10.1186/2049-9957-3-44] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2014] [Accepted: 11/12/2014] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND A better understanding of why HIV-exposed/infected children fail to attend their scheduled follow-up medical appointments for HIV-related care would allow for interventions to enhance the delivery of care. The aim of this study was to determine characteristics of the caregiver-child dyad (CCD) associated with children's non-adherence to scheduled follow-up medical appointments in HIV programs in Cameroon. METHODS We conducted a case-control analysis of the usual-care group of CCDs from the MORE CARE trial, in which the effect of mobile phone reminders for HIV-exposed/infected children in attending follow-up appointments was assessed from January to March 2013. For this study, the absence of a child at their appointment was considered a case and the presence of a child at their appointment was defined as a control. We used three multivariate binary logistic regression analyses. The best-fit model was the one which had the smallest chi-square value with the Hosmer-Lemeshow test (HLχ²). Magnitudes of associations were expressed by odds ratio (OR), with a p-value <0.05 considered as statistically significant. RESULTS We included 30 cases and 31 controls. Our best-fit model which considered the sex of the adults and children separately (HL χ²=3.5) showed that missing scheduled medical appointments was associated with: lack of formal education of the caregiver (OR 29.1, 95% CI 1.1-777.0; p=0.044), prolonged time to the next appointment/follow-up (OR [1 week increase] 1.4, 95% CI 1.03-2.0; p=0.032), and being a female child (OR 5.2, 95% CI 1.2-23.1; p=0.032). One model (HLχ²=10.5) revealed that woman-boy pairs adhered less to medical appointments compared to woman-girl pairs (OR 4.9, 95% CI 1.05-22.9; p=0.044). Another model (HLχ²=11.1) revealed that man-boy pairs were more likely to attend appointments compared to woman-girl pairs (OR 0.23, 95% CI 0.06-0.93; p=0.039). There were no statistical associations for the ages of the children or the caregivers, the study sites, or the HIV status (confirmed vs. suspected) of the children. CONCLUSION The profile of children who would not attend follow-up medical appointments in an HIV program was: a female, with a caregiver who has had no formal education, and with a longer follow-up appointment interval. There is a possibility that female children are favored by female caregivers and that male children are favored by male caregivers when they come to medical care.

Abstract
Access to pediatric HIV treatment in resource-limited settings has risen significantly. However, little is known about the quality of care that pediatric or adolescent patients receive. The objective of this study is to explore quality of HIV care and treatment in Nigeria and to determine the association between quality of care, loss-to-follow-up and mortality. A retrospective cohort study was conducted including patients ≤18 years of age who initiated ART between November 2002 and December 2011 at 23 sites across 10 states. 1,516 patients were included. A quality score comprised of 6 process indicators was calculated for each patient. More than half of patients (55.5%) were found to have a high quality score, using the median score as the cut-off. Most patients were screened for tuberculosis at entry into care (81.3%), had adherence measurement and counseling at their last visit (88.7% and 89.7% respectively), and were prescribed co-trimoxazole at some point during enrollment in care (98.8%). Thirty-seven percent received a CD4 count in the six months prior to chart review. Mortality within 90 days of ART initiation was 1.9%. A total of 4.2% of patients died during the period of follow-up (mean: 27 months) with 19.0% lost to follow-up. In multivariate regression analyses, weight for age z-score (Adjusted Hazard Ratio (AHR): 0.90; 95% CI: 0.85, 0.95) and high quality indicator score (compared a low score, AHR: 0.43; 95% CI: 0.26, 0.73) had a protective effect on mortality. Patients with a high quality score were less likely to be lost to follow-up (Adjusted Odds Ratio (AOR): 0.42; 95% CI: 0.32, 0.56), compared to those with low score. These findings indicate that providing high quality care to children and adolescents living with HIV is important to improve outcomes, including lowering loss to follow-up and decreasing mortality in this age group.

Burden of HIV infection among children aged 18 months to 14 years in Kenya: results from a nationally representative population-based cross-sectional survey. J Acquir Immune Defic Syndr 2014; 66 Suppl 1:S82-8. [PMID: 24732823 DOI: 10.1097/qai.0000000000000118] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND In Kenya, mathematical models estimate that there are approximately 220,000 children aged less than 15 years infected with HIV. We analyzed data from the second Kenya AIDS Indicator Survey (KAIS 2012) to estimate the prevalence of HIV infection among children aged 18 months to 14 years. METHODS KAIS 2012 was a nationally representative 2-stage cluster sample household survey. We studied children aged 18 months to 14 years whose parents or guardians answered questions pertaining to their children by interview. Blood specimens were collected for HIV serology and viral load measurement. RESULTS We identified 5162 children who were eligible for the study. Blood was obtained for 3681 (71.3%) children. Among child participants, 16.4% had been tested for HIV infection in the past, and among children with parents or guardians who self-reported HIV-positive status, 52.9% had been tested for HIV infection. Twenty-eight (0.9%) children tested HIV-positive in the survey. Of these, 11 had been previously diagnosed with HIV infection before the survey. All 11 children were in HIV care and receiving cotrimoxazole; 8 were on antiretorivral therapy (ART). Among those on ART, 4 were virologically suppressed. CONCLUSIONS HIV causes a substantial burden of disease in the Kenyan pediatric population. Although most children who had been diagnosed with HIV before the survey were engaged in care and treatment, they represented less than half of HIV-infected children identified in the survey. Future efforts should focus on identifying infected children and getting them into care and on suppressive ART as early as possible.

Abstract
BACKGROUND Prognostic models for children starting antiretroviral therapy (ART) in Africa are lacking. We developed models to estimate the probability of death during the first year receiving ART in Southern Africa. METHODS We analyzed data from children ≤10 years of age who started ART in Malawi, South Africa, Zambia or Zimbabwe from 2004 to 2010. Children lost to follow up or transferred were excluded. The primary outcome was all-cause mortality in the first year of ART. We used Weibull survival models to construct 2 prognostic models: 1 with CD4%, age, World Health Organization clinical stage, weight-for-age z-score (WAZ) and anemia and the other without CD4%, because it is not routinely measured in many programs. We used multiple imputation to account for missing data. RESULTS Among 12,655 children, 877 (6.9%) died in the first year of ART. We excluded 1780 children who were lost to follow up/transferred from main analyses; 10,875 children were therefore included. With the CD4% model probability of death at 1 year ranged from 1.8% [95% confidence interval (CI): 1.5-2.3] in children 5-10 years with CD4% ≥10%, World Health Organization stage I/II, WAZ ≥ -2 and without severe anemia to 46.3% (95% CI: 38.2-55.2) in children <1 year with CD4% < 5%, stage III/IV, WAZ< -3 and severe anemia. The corresponding range for the model without CD4% was 2.2% (95% CI: 1.8-2.7) to 33.4% (95% CI: 28.2-39.3). Agreement between predicted and observed mortality was good (C-statistics = 0.753 and 0.745 for models with and without CD4%, respectively). CONCLUSIONS These models may be useful to counsel children/caregivers, for program planning and to assess program outcomes after allowing for differences in patient disease severity characteristics.

Cost-effectiveness of early infant HIV diagnosis of HIV-exposed infants and immediate antiretroviral therapy in HIV-infected children under 24 months in Thailand. PLoS One 2014; 9:e91004. [PMID: 24632750 PMCID: PMC3954590 DOI: 10.1371/journal.pone.0091004] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2013] [Accepted: 01/30/2014] [Indexed: 11/19/2022] Open
Abstract
Background HIV-infected infants have high risk of death in the first two years of life if untreated. WHO guidelines recommend early infant HIV diagnosis (EID) of all HIV-exposed infants and immediate antiretroviral therapy (ART) in HIV-infected children under 24-months. We assessed the cost-effectiveness of this strategy in HIV-exposed non-breastfed children in Thailand. Methods A decision analytic model of HIV diagnosis and disease progression compared: EID using DNA PCR with immediate ART (Early-Early); or EID with deferred ART based on immune/clinical criteria (Early-Late); vs. clinical/serology based diagnosis and deferred ART (Reference). The model was populated with survival and cost data from a Thai observational cohort and the literature. Incremental cost-effectiveness ratio per life-year gained (LYG) was compared against the Reference strategy. Costs and outcomes were discounted at 3%. Results Mean discounted life expectancy of HIV-infected children increased from 13.3 years in the Reference strategy to 14.3 in the Early-Late and 17.8 years in Early-Early strategies. The mean discounted lifetime cost was $17,335, $22,583 and $29,108, respectively. The cost-effectiveness ratio of Early-Late and Early-Early strategies was $5,149 and $2,615 per LYG, respectively as compared to the Reference strategy. The Early-Early strategy was most cost-effective at approximately half the domestic product per capita per LYG ($4,420 in Thailand 2011). The results were robust in deterministic and probabilistic sensitivity analyses including varying perinatal transmission rates. Conclusion In Thailand, EID and immediate ART would lead to major survival benefits and is cost- effective. These findings strongly support the adoption of WHO recommendations as routine care.

Alvarez-Uria G. Description of the cascade of care and factors associated with attrition before and after initiating antiretroviral therapy of HIV infected children in a cohort study in India. PeerJ 2014; 2:e304.

Abstract
In low- and middle-income countries, the attrition across the continuum of care of HIV infected children is not well known. The aim of this study was to investigate predictors of mortality and loss to follow up (LTFU) in HIV infected children from a cohort study in India and to describe the cascade of care from HIV diagnosis to virological suppression after antiretroviral therapy (ART) initiation. Multivariable analysis was performed using competing risk regression. The cumulative incidence of attrition due to mortality or LTFU after five year of follow-up was 16% from entry into care to ART initiation and 24.9% after ART initiation. Of all children diagnosed with HIV, it was estimated that 91.9% entered into care, 77.2% were retained until ART initiation, 58% stayed in care after ART initiation, and 43.4% achieved virological suppression on ART. Approximately half of the attrition occurred before ART initiation, and the other half after starting ART. Belonging to socially disadvantaged communities and living >90 min from the hospital were associated with a higher risk of attrition. Being >10 years old and having higher 12-month risk of AIDS (calculated using the absolute CD4 lymphocyte count and the age) were associated with an increased risk of mortality. These findings indicate that we should consider placing more emphasis on promoting research and implementing interventions to improve the engagement of HIV infected children in pre-ART care. The results of this study can be used by HIV programmes to design interventions aimed at reducing the attrition across the continuum of care of HIV infected children in India.

Abstract
UNLABELLED HIV is the top and tuberculosis is the second leading cause of death from infectious disease worldwide, with an estimated 8.7 million incident cases of tuberculosis and 2.5 million new HIV infections annually. The World Health Organization estimates that HIV prevalence among children with tuberculosis, in countries with moderate to high prevalence, ranges from 10 to 60%. The mechanisms promoting susceptibility of people with HIV to tuberculosis disease are incompletely understood, being likely caused by multifactorial processes. Paediatric tuberculosis and HIV have overlapping clinical manifestations, which could lead to missed or late diagnosis. Although every effort should be made to obtain a microbiologically-confirmed diagnosis in children with tuberculosis, in reality this may only be achieved in a minority, reflecting their paucibacillary nature and the difficulties in obtain samples. Rapid polymerase chain reaction tests, such as Xpert MTB/RIF assay, are increasingly used in children. The use of less or non invasive methods of sample collection, such as naso-pharyngeal aspirates and stool samples for a polymerase chain reaction-based diagnostic test tests and mycobacterial cultures is promising technique in HIV negative and HIV positive children. Anti-tuberculosis treatment should be started immediately at diagnosis with a four drug regimen, irrespective of the disease severity. Moreover, tuberculosis disease in an HIV infected child is considered to be a clinical indication for initiation of antiretroviral treatment. The World Health Organization recommends starting antiretroviral treatment in children as soon as anti-tuberculosis treatment is tolerated and within 2- 8 weeks after initiating it. The treatment of choice depends on the child's age and availability of age-appropriate formulations, and potential drug interactions and resistance. Treatment of multidrug resistant tuberculosis in HIV-infected children follows same principles as for HIV uninfected children. There are conflicting results on effectiveness of isoniazid preventive therapy in reducing incidence of tuberculosis disease in children with HIV. CONCLUSION Data on HIV/TB co-infection in children are still lacking. There are on-going large clinical trials on the prevention and treatment of TB/HIV infection in children that hopefully will help to guide an evidence-based clinical practice in both resource-rich and resource-limited settings.HIV is the top and tuberculosis is the second leading cause of death from infectious disease worldwide, with an estimated 8.7 million incident cases of tuberculosis and 2.5 million new HIV infections annually. The World Health Organization estimates that HIV prevalence among children with tuberculosis, in countries with moderate to high prevalence, ranges from 10 to 60%. The mechanisms promoting susceptibility of people with HIV to tuberculosis disease are incompletely understood, being likely caused by multifactorial processes.

Abstract
OBJECTIVE To estimate the prevalence of oral mucosal diseases and dental caries among HIV-infected children receiving antiretroviral treatment (ART) in West Africa and to identify the factors associated with the prevalence of oral mucosal lesions. METHODS Multicentre cross-sectional survey in five paediatric HIV clinics in Côte d'Ivoire, Mali and Sénégal. A standardised examination was performed by trained dentists on a random sample of HIV-infected children aged 5-15 years receiving ART. The prevalence of oral and dental lesions and mean number of decayed, missing/extracted and filled teeth (DMFdefT) in temporary and permanent dentition were estimated with their 95% confidence interval (95% CI). We used logistic regression to explore the association between children's characteristics and the prevalence of oral mucosal lesions, expressed as prevalence odds ratio (POR). RESULTS The median age of the 420 children (47% females) enrolled was 10.4 years [interquartile range (IQR) = 8.3-12.6]. The median duration on ART was 4.6 years (IQR = 2.6-6.2); 84 (20.0%) had CD4 count<350 cells/mm(3). A total of 35 children (8.3%; 95% CI: 6.1-11.1) exhibited 42 oral mucosal lesions (24 were candidiasis); 86.0% (95% CI = 82.6-89.3) of children had DMFdefT ≥ 1. The presence of oral mucosal lesions was independently associated with CD4 count < 350 cells/mm(3) (POR = 2.96, 95% CI = 1.06-4.36) and poor oral hygiene (POR = 2.69, 95% CI = 1.07-6.76). CONCLUSIONS Oral mucosal lesions still occur in HIV-infected African children despite ART, but rarely. However, dental caries were common and severe in this population, reflecting the need to include oral health in the comprehensive care of HIV.

Abstract
There are 3.4 million children infected with HIV worldwide, with up to 2.6 million eligible for treatment under current guidelines. However, roughly 70% of infected children are not receiving live-saving HIV care and treatment. Strengthening case finding through improved diagnosis strategies, and actively linking identified HIV-infected children to care and treatment is essential to ensuring that these children benefit from the care and treatment available to them. Without attention or advocacy, the majority of these children will remain undiagnosed and die from complications of HIV. In this article, we summarize the challenges of identifying HIV-infected infants and children, review currently available evidence and guidance, describe promising new strategies for case finding, and make recommendations for future research and interventions to improve identification of HIV-infected infants and children.

Anaemia and zidovudine-containing antiretroviral therapy in paediatric antiretroviral programmes in the IeDEA Paediatric West African Database to evaluate AIDS. J Int AIDS Soc 2013; 16:18024.

Abstract
INTRODUCTION There is a risk of anaemia among HIV-infected children on antiretroviral therapy (ART) containing zidovudine (ZDV) recommended in first-line regimens in the WHO guidelines. We estimated the risk of severe anaemia after initiation of a ZDV-containing regimen in HIV-infected children included in the IeDEA West African database. METHODS Standardized collection of data from HIV-infected children (positive PCR<18 months or positive serology ≥ 18 months) followed up in HIV programmes was included in the regional IeDEA West Africa collaboration. Ten clinical centres from seven countries contributed (Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal) to this collection. Inclusion criteria were age <16 years and starting ART. We explored the data quality of haemoglobin documentation over time and the incidence and predictors of severe anaemia (Hb<7 g/dL) per 100 child-years of follow-up over the duration of first-line antiretroviral therapy. RESULTS As of December 2009, among the 2933 children included in the collaboration, 45% were girls, median age was five years; median CD4 cell percentage was 13%; median weight-for-age z-score was-2.7; and 1772 (60.4%) had a first-line ZDV-containing regimen. At baseline, 70% of the children with a first-line ZDV-containing regimen had a haemoglobin measure available versus 76% in those not on ZDV (p ≤ 0.01): the prevalence of severe anaemia was 3.0% (n=38) in the ZDV group versus 10.2% (n=89) in those without (p<0. 01). Over the first-line follow-up, 58.9% of the children had ≥ 1 measure of haemoglobin available in those exposed to ZDV versus 60.4% of those not (p=0.45). Severe anaemia occurred in 92 children with an incidence of 2.47 per 100 child-years of follow-up in those on a ZDV-containing regimen versus 4.25 in those not (p ≤ 0.01). Adjusted for age at ART initiation and first-line regimen, a weight-for-age z-score ≤-3 was a strong predictor associated with a 5.59 times risk of severe anaemia (p<0.01). CONCLUSIONS Severe anaemia is frequent at baseline and guides the first-line ART prescription, but its incidence seems rare among children on ART. Severe malnutrition at baseline is a strong predictor for development of severe anaemia, and interventions to address this should form an integral component of clinical care.

Abstract
BACKGROUND Retention of children in HIV care is essential for prevention of disease progression and mortality. METHODS Retrospective cohort of children (aged 0 to <15 years) initiating antiretroviral treatment (ART) at health facilities in Kenya, Mozambique, Rwanda, and Tanzania, from January 2005 to June 2011. Retention was defined as the proportion of children known to be alive and attending care at their initiation facility; lost to follow-up (LTF) was defined as no clinic visit for more than 6 months. Cumulative incidence of ascertained survival and retention after ART initiation was estimated through 24 months using Kaplan-Meier methods. Factors associated with LTF and death were assessed using Cox proportional hazard modeling. RESULTS A total of 17,712 children initiated ART at 192 facilities: median age was 4.6 years [interquartile ratio (IQR), 1.9-8.3], median CD4 percent was 15% (IQR, 10-20) for children younger than 5 years and 265 cells per microliter (IQR, 111-461) for children aged 5 years or older. At 12 and 24 months, 80% and 72% of children were retained with 16% and 22% LTF and 5% and 7% known deaths, respectively. Retention ranged from 71% to 95% at 12 months and from 62% to 93% at 24 months across countries, respectively, and was lowest for children younger than 1 year (51% at 24 months). LTF and death were highest in children younger than 1 year and children with advanced disease. CONCLUSIONS Retention was lowest in young children and differed across country programs. Young children and those with advanced disease are at highest risk for LTF and death. Further evaluation of patient- and program-level factors is needed to improve health outcomes.

Abstract
This study evaluates HIV infant diagnosis on DBS using Biocentric HIV1-DNA and HIV1-RNA assays, in field conditions in Côte d'Ivoire. Paediatric screening was offered to children≤3 years in clinical sites in Côte d'Ivoire in 2008. For each HIV-infected child, two non-infected children were included and blood samples were collected. HIV-DNA results obtained on EDTA blood samples with Biocentric assay were the reference for HIV infant diagnosis. Plasma and DBS viral loads were measured using HIV-RNA Biocentric assay. DBS samples were also tested for HIV-DNA detection using both Biocentric and Amplicor Roche assays. Sensitivity, specificity and concordance between tests were calculated. Overall samples from 138 HIV-exposed children, 46 infected, 92 non-infected were included. All tests were 100% sensitive and specific including 100% concordance with the two HIV-DNA assays. The median level of HIV-DNA on EDTA samples was 3.15 log10 copies/10(6) PBMCs; the median level of HIV RNA in plasma and DBS were respectively 5.82 and 5.17 log10 copies/ml (Pearson's correlation R2=0.92, p<0.0001). The threshold for detectable HIV-RNA on DBS was 3.3 log10. Although there are differences between viral load measured on DBS and plasma, the two Biocentric assays present very good performances for HIV infant diagnosis on DBS while cheap and feasible.

Abstract
OBJECTIVE With the aim of reducing pediatric loss to follow-up (LTFU) from HIV clinical care programs in sub-Saharan Africa, we sought to understand the personal and socio-cultural factors associated with the behavior of caregivers taking HIV-infected and -exposed children for care in western Kenya. METHODS Between May and August, 2010, in-depth interviews were conducted with 26 purposively sampled caregivers caring for HIV-infected (7), HIV-exposed (17) and HIV-unknown status (2) children, documented as LTFU from an urban and rural HIV care clinic. All were women with a majority (77%) being biological parents. Interviews were audio-recorded, transcribed and content analyzed. RESULTS Thematic content analysis of the women's perceptions revealed that their decision about routinely taking their children to HIV care involved multiple levels of factors including: (1) intrapersonal: transport costs, food availability, time constraints due to work commitment, disclosure of HIV status for both mother and child, perception that child is healthy and religious beliefs; (2) interpersonal: unsupportive male partner, stigma by the family and family conflicts; (3) community: cultural norms, changing community dynamics and perceived stigma; (4) health care system: clinic location, lack of patient-centered care, delays at the clinic and different appointment schedules (mother and child). Furthermore, the factors across these different levels interacted with each other in a complex way, illustrating the challenges women face in taking their children to HIV care. CONCLUSION The complexity and interconnectedness of the factors underlying retention of children in HIV care perceived by these women caregivers suggests that interventions to reduce pediatric LTFU need to be holistic and address multiple socio-ecological levels. Patient-centered care that integrates a family-centered approach to HIV pediatric care is recommended.

Abstract
OBJECTIVE To determine how routine inpatient provider-initiated HIV testing differs from traditional community-based client-initiated testing with respect to clinical characteristics of children identified and outcomes of outpatient HIV care. DESIGN Prospective observational cohort. METHODS Routine clinical data were collected from children identified as HIV-infected by either testing modality in Lilongwe, Malawi, in 2008. After 1 year of outpatient HIV care at the Baylor College of Medicine Clinical Center of Excellence, outcomes were assessed. RESULTS Of 742 newly identified HIV-infected children enrolling into outpatient HIV care, 20.9% were identified by routine inpatient HIV testing. Compared with community-identified children, hospital-identified patients were younger (median 25.0 vs 53.5 months), with more severe disease (22.2% vs 7.8% WHO stage IV). Of 466 children with known outcomes, 15.0% died within the first year of HIV care; median time to death was 15.0 weeks for community-identified children vs 6.0 weeks for hospital-identified children. The strongest predictors of early mortality were severe malnutrition (hazard ratio, 4.3; 95% confidence interval, 2.2-8.3), moderate malnutrition (hazard ratio, 3.2; confidence interval, 1.6-6.6), age < 12 months (hazard ratio, 3.2; 95% confidence interval, 1.4-7.2), age 12 to 24 months (hazard ratio, 2.5; 95% confidence interval, 1.1-5.7), and WHO stage IV (hazard ratio, 2.2; 95% confidence interval, 1.1-4.6). After controlling for other variables, hospital identification did not independently predict mortality. CONCLUSIONS Routine inpatient HIV testing identifies a subset of younger HIV-infected children with more severe, rapidly progressing disease that traditional community-based testing modalities are currently missing.

Abstract
BACKGROUND In Africa, success of antiretroviral treatment (ART) seems to lag behind in children compared with adults, and high therapeutic failure rates have been reported. We aimed to identify prevalence and determinants of virological failure in HIV-infected children treated under programmatic conditions. METHODS All patients <18 years on ART presenting to the HIV clinic at the Bamenda Regional Hospital, a secondary referral hospital in rural Cameroon, from September 2010 to August 2011, were enrolled in this cross-sectional study. Clinical data, self-reported adherence, CD4(+) T-cell counts and viral load were recorded. Therapeutic drug monitoring was performed on stored plasma samples. Determinants of virological failure were identified using descriptive statistics and logistic regression. RESULTS A total of 230 children with a mean age of 8.9 years (sd 3.7) were included. At the time of analysis, the mean duration of HAART was 3.5 years (sd 1.7) and 12% had a CD4(+) T-cell count <200 cells/µl. In total, 53% of children experienced virological failure (>200 copies/ml). Among children on nevirapine (NVP), plasma levels were subtherapeutic in 14.2% and supratherapeutic in 42.2%. Determinants of virological failure included male sex, lower CD4(+) T-cell counts, subtherapeutic drug levels, longer time on ART and a deceased mother. Poor adherence was associated with subtherapeutic NVP plasma levels and advanced disease stages (WHO stage 3/4). CONCLUSIONS This study demonstrates high virological failure rates and a high variability of NVP plasma levels among HIV-infected children in a routine ART programme in rural Cameroon. Strategies to improve adherence to ART in HIV-infected children are urgently needed.

Abstract
BACKGROUND We describe health care resource utilization among HIV-1-infected children who have not yet undergone antiretroviral treatment (ART) in Abidjan, Côte d'Ivoire. METHODS HIV-infected children enrolled prospectively in an HIV care programme in 2 health facilities in Abidjan (2004-2009) were followed up from date of inclusion until database closeout, death, ART initiation, or loss to follow-up (no clinical contact for more than 6 months). Incidences of health care resource utilization (outpatient care, inpatient day care, and hospitalization) were described according to severe morbidity and mixed effect log linear models were computed to identify associated factors. RESULTS Overall, 405 children were included, entering care at a median age of 4.5 years, 66.9% were receiving cotrimoxazole prophylaxis, and 27.7% met 2006 WHO criteria for immunodeficiency by age. The median follow-up time was 11.6 months (interquartile range: 1.4; 30.7). Overall, 371 clinical events occurred in 162 children yielding to an incidence rate (IR) of 60.9/100 child-years (CY) [95% confidence interval (CI): 55.1 to 67.2]: 57% of clinical events led to outpatient care (IR: 33/100 CY), 38% to inpatient day care (IR: 22/100 CY), and 10% to hospitalization (IR: 5.9/100 CY). Further medical examinations were made allowing confirmed diagnoses in 40% of those (IR: 22.4/100 CY). Outpatient care was less common among immunodeficient children than those not (relative risk [RR] = 0.32, 95% CI: 0.18 to 0.56), in those whose main caregivers are both parents compared with those who are primarily cared for by their mother only (RR = 0.34, 95% CI: 0.15 to 0.77). CONCLUSION Untreated HIV-infected children require substantial inpatient and outpatient care in a context where ART is scaling up but still not available to all.

Abstract
BACKGROUND In adults it is well documented that there are substantial losses to the programme between HIV testing and start of antiretroviral therapy (ART). The magnitude and reasons for loss to follow-up and death between HIV diagnosis and start of ART in children are not well defined. METHODS We searched the PubMed and EMBASE databases for studies on children followed between HIV diagnosis and start of ART in low-income settings. We examined the proportion of children with a CD4 cell count/percentage after after being diagnosed with HIV infection, the number of treatment-eligible children starting ART and predictors of loss to programme. Data were extracted in duplicate. RESULTS Eight studies from sub-Saharan Africa and two studies from Asia with a total of 10,741 children were included. Median age ranged from 2.2 to 6.5 years. Between 78.0 and 97.0% of HIV-infected children subsequently had a CD4 cell count/percentage measured, 63.2 to 90.7% of children with an eligibility assessment met the eligibility criteria for the particular setting and time and 39.5 to 99.4% of the eligible children started ART. Three studies reported an association between low CD4 count/percentage and ART initiation while no association was reported for gender. Only two studies reported on pre-ART mortality and found rates of 13 and 6 per 100 person-years. CONCLUSION Most children who presented for HIV care met eligibility criteria for ART. There is an urgent need for strategies to improve the access to and retention to care of HIV-infected children in resource-limited settings.

Predictors of loss to follow-up among children in the first and second years of antiretroviral treatment in Johannesburg, South Africa. Glob Health Action 2013; 6:19248. [PMID: 23364098 PMCID: PMC3556704 DOI: 10.3402/gha.v6i0.19248] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2012] [Revised: 11/13/2012] [Accepted: 11/13/2012] [Indexed: 01/03/2023] Open
Abstract
Background Ninety percent of the world's 2.1 million HIV-infected children live in sub-Saharan Africa, and 2.5% of South African children live with HIV. As HIV care and treatment programmes are scaled-up, a rise in loss to follow-up (LTFU) has been observed. Objective The aim of the study was to determine the rate of LTFU in children receiving antiretroviral treatment (ART) and to identify baseline characteristics associated with LTFU in the first year of treatment. We also explored the effect of patient characteristics at 12 months treatment on LTFU in the second year. Methods The study is an analysis of prospectively collected routine data of HIV-infected children at the Harriet Shezi Children's Clinic (HSCC) in Soweto, Johannesburg. Cox proportional hazards models were fitted to investigate associations between baseline characteristics and 12-month characteristics with LTFU in the first and second year on ART, respectively. Results The cumulative probability of LTFU at 12 months was 7.3% (95% CI 7.1–8.8). In the first 12 months on ART, independent predictors of LTFU were age <1 year at initiation, recent year of ART start, mother as a primary caregiver, and being underweight (WAZ ≤ −2). Among children still on treatment at 1 year from ART initiation, characteristics that predicted LTFU within the second year were recent year of ART start, mother as a primary caregiver, being underweight (WAZ ≤ −2), and low CD4 cell percentage. Conclusions There are similarities between the known predictors of death and the predictors of LTFU in the first and second years of ART. Knowing the vital status of children is important to determine LTFU. Although HIV-positive children cared for by their mothers appear to be at greater risk of becoming LTFU, further research is needed to explore the challenges faced by mothers and other caregivers and their impact on long-term HIV care. There is also a need to investigate the effects of differential access to ART between mothers and children and its impact on ART outcomes in children.

Abstract
OBJECTIVE Little is known about the cost of paediatric antiretroviral treatment (ART) in low-income and middle-income countries. We analysed the average cost of providing paediatric ART in South Africa during the first 2 years after ART initiation, stratified by patient outcomes. METHODS We collected data on outpatient resource use and treatment outcomes of 288 children in two Johannesburg public clinics, Empilweni Services and Research Unit (ESRU) and Harriet Shezi Children's Clinic (HSCC) from 2005 to 2009. Patient-level resource use was estimated from patient records. Unit cost data came from site accounts and public-sector sources. Patient outcomes at month 12 and 24 after initiation were defined based on patients' weight CD4 cell counts/percentages, viral loads, and the presence of new WHO stage 3/4 conditions. RESULTS Median age/CD4 percentage at initiation was 4.03 years/12.40% in ESRU and 5.84 years/14.05% in HSCC, respectively. Sixty-two and 91% of patients remained in care and responding to treatment at month 12 in ESRU and HSCC, respectively, and 68 and 80% at month 24. The average cost per patient in care and responding was US$ 830 in year 1 and US$ 717 in year 2 in ESRU and US$ 678 and US$ 782 in HSCC. Antiretroviral drugs comprised 33-52% of total cost, clinic visits 23-31%, lab tests 12-16%, and fixed costs 8-18%. CONCLUSIONS Costs varied between the two clinics but were comparable with those of adult ART. Few very young children accessed ART in either clinic and those who did were already very ill, emphasizing the importance of early infant treatment.

Abstract
BACKGROUND The aim of this study was to describe 3-year mortality rates, associated risk factors, and long-term clinical outcomes of children enrolled in China's national free pediatric antiretroviral therapy (ART) program. METHODS Records were abstracted from the national human immunodeficiency virus (HIV)/AIDS case reporting and national pediatric ART databases for all HIV-positive children ≤15 years old who initiated ART prior to December 2010. Mortality risk factors over 3 years of follow-up were examined using Cox proportional hazards regression models. Life tables were used to determine survival rate over time. Longitudinal plots of CD4(+) T-cell percentage (CD4%), hemoglobin level, weight-for-age z (WAZ) score, and height-for-age z (HAZ) score were created using generalized estimating equation models. RESULTS Among the 1818 children included in our cohort, 93 deaths were recorded in 4022 child-years (CY) of observed time for an overall mortality rate of 2.31 per 100 CY (95% confidence interval [CI], 1.75-2.78). The strongest factor associated with mortality was baseline WAZ score <-2 (adjusted hazard ratio [HR] = 9.1; 95% CI, 2.5-33.2), followed by World Health Organization stage III or IV disease (adjusted HR = 2.4; 95% CI, 1.1-5.2), and hemoglobin <90 g/L (adjusted HR = 2.2; 95% CI, 1.2-3.9). CD4%, hemoglobin level, WAZ score, and HAZ score increased over time. CONCLUSIONS Our finding that 94% of children engaged in this program are still alive and of improved health after 3 years of treatment demonstrates that China's national pediatric ART program is effective. This program needs to be expanded to better meet treatment demands, and efforts to identify HIV-positive children earlier must be prioritized.

Abstract
BACKGROUND The long-term effects of combined antiretroviral therapy (cART) on CD4 percentage in HIV-infected children are incompletely understood, with evidence from resource-deprived areas particularly scarce even though most children with HIV live in such settings. We sought to describe this relationship. METHODS Observational longitudinal data from cART-naive children enrolled between December 2004 and May 2010 into an HIV care and treatment program in Kinshasa, Democratic Republic of Congo were analyzed. To estimate the effect of cART on CD4 percentage while accounting for time-dependent confounders affected by prior exposure to cART, a marginal structural linear mean model was used. RESULTS Seven hundred ninety children were active for 2090 person-years and a median of 31 months; 619 (78%) initiated cART. At baseline, 405 children (51%) were in HIV clinical stage 3 or 4; 528 (67%) had advanced or severe immunodeficiency. Compared with no cART, the estimated absolute rise in CD4 percentage was 6.8% [95% confidence interval (CI), 4.7% to 8.9%] after 6 months of cART, 8.6% (95% CI, 7.0% to 10.2%) after 12 months, and 20.5% (95% CI, 16.1% to 24.9%) after 60 months. cART-mediated CD4 percentage gains were slowest but greatest among children with baseline CD4 percentage <15. The cumulative incidence of recovery to "not significant" World Health Organization age-specific immunodeficiency was lower if cART was started when immunodeficiency was severe rather than mild or advanced. CONCLUSIONS cART increased CD4 percentages among HIV-infected children in a resource-deprived setting, as previously noted among children in the United States. More gradual and protracted recovery in children with lower baseline CD4 percentages supports earlier initiation of pediatric cART.

Abstract
Background An estimated 2.5 million children were living with HIV/AIDS at the end of 2009, 2.3 million (92%) in sub-Saharan Africa. Without treatment, a third of children with HIV will die of AIDS before their first birthday, half dying before two years of age. Hence, this study aimed to assess magnitude and predictors of mortality among children on Antiretroviral Therapy (ART) at a referral hospital in North-West Ethiopia. Methods Institution based retrospective follow up study was carried out among HIV-positive children from January 1st, 2006 - March 31st, 2011. Information on relevant variables was collected from patients’ charts and registries. Life table was used to estimate the cumulative survival of children. Log rank tests were employed to compare survival between the different categories of the explanatory variables. Multivariate Cox proportional hazards model was fitted to identify predictors of mortality. Results A total of 549 records were included in the analysis. The mean age at initiation of treatment was 6.35 ±3.78 SD years. The median follow up period was 22 months. At the end of the follow up, 41(7.5%) were dead and 384(69.9%) were alive. Mortality was 4.0 deaths per 100 child-years of follow-up period. The cumulative probabilities of survival at 3, 6, 12, 24, and 60 months of ART were 0.96, 0.94, 0.93, 0.92 and 0.83 respectively. Majority (90.2%) of the deaths occurred within the first year of treatment. Absence of cotrimoxazole preventive therapy (adjusted hazard ratio [AHR] = 4.74, 95% CI: 2.17, 10.34), anaemia (haemoglobin level < 10gm/dl) (AHR=2.44, 95% CI: 1.26, 4.73), absolute CD4 cell count below the threshold for severe immunodeficiency (AHR=2.24, 95% CI: 1.07, 4.69) and delayed or regressing developmental milestones at baseline (AHR=6.31, 95% CI: 2.52, 15.83) were predictors of mortality. Conclusions There was a high rate of early mortality. Hence, starting ART very early reduces disease progression and early mortality; close follow up of all children of HIV-positive mothers is recommended to make the diagnosis and start treatment at an earlier time before they develop severe immunodeficiency.
