Effects of undernutrition on mortality of HIV-infected children after initiation of antiretroviral therapy in Ethiopia: A systematic review and meta-analysis. Heliyon 2024; 10:e29308. [PMID: 38601598 PMCID: PMC11004412 DOI: 10.1016/j.heliyon.2024.e29308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Revised: 04/01/2024] [Accepted: 04/04/2024] [Indexed: 04/12/2024] Open
Abstract
Background Undernutrition is the leading cause of mortality among children infected with HIV particularly in resource-deprived settings. Despite several studies were disclosed the effect of undernutrition on mortality of children living with HIV in Ethiopia, the findings were fragmented and inconclusive. Therefore, this review aimed to determine the pooled effects of undernutrition on mortality of children infected with HIV in Ethiopia. Methods The search were performed using international online electronic data bases (MEDLINE/though PubMed, Google scholar, Hinari, Scopus and open Google). The review included only retrospective/prospective cohort studies reporting the effects of undernutrition on mortality of children infected with HIV. Heterogeneity between included studies was assessed using Cochrane Q-test and the I2 statistics. Sub-group analysis was done by study regions, sample size and publication year. Results A total of 1345 articles were identified from databases. Among these, 14 studies met the inclusion criteria and included in the study. Meta-analysis of 4 studies revealed that stunting has a significant effect on mortality of children infected with HIV (AHR: 3.36; 95 % CI: 2.95-3.77). Of 14 included studies, 6 articles indicated that wasting has a significant effect on mortality in children infected with HIV (AHR: 3.93; 95 % CI: 2.56-5.30) as compared to their counterparts. Furthermore, the pooled effect of 8 studies showed that underweight has 3.4 times hazard of death among children who lived with HIV as compared to well-nourished children. Conclusion This review revealed that undernutrition has deleterious effect on mortality of children infected with HIV/AIDS by disease progression and prone the children to serious opportunistic infections. From the study, the authors recommended that nutritional status of children on antiretroviral therapy need to be evaluated regularly.

Abstract
OBJECTIVES To understand the survival in a cohort of children living with HIV/AIDS (CLHAs) and to study the factors associated with survival in CLHAs in government antiretroviral therapy (ART) centres in Mumbai, India. DESIGN This is a retrospective cohort analysis. SETTING Data from electronic ART records of children from 15 ART centres in Mumbai, Maharashtra, India. PARTICIPANTS 2224 CLHAs registered in one of these ART centres from 2004 until October 2019. CLHAs up to the age of 18 at the time of registration were considered for these analyses. PRIMARY AND SECONDARY OUTCOMES We accessed the following data: date of test, date of initiation of ART, date of last follow-up, age at the time of registration, gender, potential route of infection, baseline CD4 counts, ART regimen, adherence and presence of co-infection (TB). We estimated the survival probabilities, plotted the Kaplan-Meier survival graphs and estimated HRs for mortality. RESULTS The mortality rate in our population was 22.75 (95% CI 20.02 to 25.85) per 1000 person-years. The 1-year survival was 0.92 (95% CI 0.91 to 0.93), 0.89 (95% CI 0.88 to 0.91) at 5 years and 0.85 (95% CI 0.83 to 0.87) at 10 years after initiation of ART. Children with adherence less than 80% had lowest survival in the first year (0.54, 95% CI 0.46 to 0.61). It reduced drastically at 5 and 10 years. After adjusting for demographic and clinical parameters, mortality was associated with poor adherence (<80%) (HR 11.70, 95% CI 8.82 to 15.53; p<0.001). However, CD4 counts of greater than 200 and age more than 1 year were protective. CONCLUSIONS Poor adherence to ART and low CD4 counts were significantly associated with higher mortality. Adherence counselling should be an important component of CLHA monitoring in all ART centres. It is also important to identify children early in the infection and start ART medications appropriately.

Abstract
HIV infection and undernutrition remain significant public health concerns for infants and children. In infants and children under these conditions, undernutrition is one of the leading causes of death. Proper management of nutrition and related nutrition complications in these groups with increased nutrition needs are prominent challenges, particularly in HIV-prevalent poor-resource environments. Several studies support the complexity of the relation between HIV infection, nutrition, and the immune system. These elements interact and create a vicious circle of poor health outcomes. Recent studies on the use of probiotics as a novel approach to manage microbiome imbalance and gut-mucosal impairment in HIV infection are gaining attention. This new strategy could help to manage dysbiosis and gut-mucosal impairment by reducing immune activation, thereby potentially forestalling unwanted health outcomes in children with HIV. However, existing trials on HIV-infected children are still insufficient. There are also conflicting reports on the dosage and effectiveness of single or multiple micronutrient supplementation in the survival of HIV-infected children with severe acute malnutrition. The WHO has published guidelines that include time of initiation of antiretroviral therapy for HIV-pregnant mothers and their HIV-exposed or HIV-infected children, micronutrient supplementation, dietary formulations, prevention, and management of HIV therapy. However, such guidelines need to be reviewed owing to recent advances in the field of nutrition. There is a need for new intervention studies, practical strategies, and evidence-based guidelines to reduce the disease burden, improve adherence to treatment regimen, and enhance the nutrition, health, and well-being of HIV-infected infants and children. This review provides up-to-date scientific information on current knowledge and existing challenges for nutrition therapy in HIV-infected infants and children. Moreover, it presents new research findings that could be incorporated into current guidelines.

Assessing the Effectiveness of a Telemedicine Initiative in Clinical Management of Children Living with HIV/AIDS in Maharashtra, India. Curr HIV Res 2021; 19:201-215. [PMID: 33397239 DOI: 10.2174/1573399817666210104102825] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 11/26/2020] [Accepted: 11/26/2020] [Indexed: 11/22/2022]
Abstract
AIMS To evaluate the effectiveness of telemedicine in the clinical management of children living with HIV/AIDS in resource-limited settings ; Background: Telemedicine is an important mechanism for service delivery in health care settings, both in resource-rich and resource-poor settings. Such service delivery mechanisms have shown to be associated with virologic suppression and higher CD4 counts. These services are also associated with improved access, shorter visiting times, and higher patient satisfaction. ; Objective: We designed the present two-group comparison study to compare the clinical evaluation and management of children in the anti-retroviral therapy (ART) centres linked to telemedicine facility with those who are not linked to this facility in Maharashtra, India. ; Methods: We analysed clinical records from six ART centres in Maharashtra; of these, 250 children were in the linked ART centres and 301 were in the non-linked ART centres. The outcomes were classified according to investigations, management, and monitoring. For management, we evaluated: 1) Initiation of cotrimoxazole prophylaxis; 2) Children not initiated on ART when required; 3) ART regime after appropriate investigations; and 4) Change of regime (if immunologically indicated). For monitoring, we assessed the haematological monitoring of children on ART. ; Results: The mean (SD) ages of children in linked and non-linked ART centres were 10.8 (4.6) and 10.9 (4.6) years, respectively (p=0.80). After adjusting for individual and structural level variables, physical examination (OR: 2.0, 95% CI; 1.2, 3.2), screening for tuberculosis (OR: 12.9, 95% CI: 2.0, 82.9) and cotrimoxazole prophylaxis were significantly more likely in the linked centres compared with non-linked centres (OR: 1.8, 95% CI: 1.4, 2.2). A higher proportion of children eligible for ART were not initiated on treatment in the non-linked centres compared with linked centres (26% vs. 8%, p=0.06). Children were less likely to be initiated on zidovudine-based regimens without baseline haemoglobin or with baseline haemoglobin of less than 9 gm% in linked centres (OR: 0.7, 95% CI: 0.6, 0.8). Similarly, children in the linked centres were less likely to have been started on nevirapine-based regimens without baseline liver enzymes (OR: 0.8, 95% CI: 0.7, 0.9). ; Conclusion: Thus, the overall clinical management of Children Living with HIV/ AIDS (CLHA) was better in ART centres linked with the telemedicine initiative compared with those who were not linked. Children in the linked ART centres were more likely to have a complete baseline assessment (physical, hematological, radiological, and screening for TB); the presence of a pediatrician in the centres was helpful.

Abstract
BACKGROUND Delays in early infant diagnosis and antiretroviral treatment (ART) initiation in developing countries frequently result in malnutrition at initial presentation with associated higher mortality and delayed immune recovery. The optimal timing of ART initiation is yet to be established. METHODS Eighty-two children admitted with HIV and severe acute malnutrition (SAM) between July 2012 and December 2015 were enrolled. Patients were randomized to initiate ART within 14 days from admission (early arm) or delay ART initiation until nutritional recovery and >14 days after admission (delayed arm). All patients received a standardized treatment and feeding protocol and were followed to 48 weeks. RESULTS The mean age of the patients at baseline was 23.3 months (standard deviation [SD], 27.9; range, 1.6-129 months). The mean time from admission to ART initiation was 5.6 days (SD, 4.4) in the early arm and 23 days (SD, 5.8) in the delayed arm (P < .001). There was no significant difference in mortality (P = .62), virologic response (P = .53), and anthropometric response (P = .57) between the 2 groups at 48 weeks. However, the rates of change in CD4, viral load, weight for age z score, and height for age z score occurred earlier and favored the delayed arm at early time points but were not significant at 24 and 48 months. CONCLUSIONS Despite initial improved responses in the delayed arm, lack of difference in outcome at 48 weeks supports a pragmatic approach with earlier ART initiation in children living with HIV admitted with SAM.In this randomised controlled study of ART initiation in children admitted with HIV and severe acute malnutrition (SAM), despite initial improved responses in the delayed arm, lack of difference in outcome at 48 weeks supports a pragmatic approach with earlier ART initiation in children living with HIV admitted with SAM.

Abstract
Objective: To determine the survival rate and predictors of HIV-infected children on antiretroviral therapy at two selected facilities in North Ethiopia. Methods: A facility-based retrospective cohort study was conducted in Debre Tabor General Hospital and Dessie Referral Hospital from December 2005 to November 2015. A total of 426 records were included in the study. Multivariable Cox proportional hazards regression model was used to identify independent predictors of survival. Results: At the end of follow-up, 97 (22.9%) HIV-infected children died and 325 (77.1%) were alive. The probabilities of survival at 12, 24, 36 and 48 months of on antiretroviral therapy were 0.91, 0.85, 0.84 and 0.80, respectively. The median survival time was 91.6 months (95% confidence interval: 89.0–94.2). Almost half (51%) of the deaths occurred within the first 2 years of treatment. Study participants who had poor adherence to antiretroviral therapy (adjusted hazard ratio = 3.0; 95% confidence interval: 1.2–7.5) and who started antiretroviral therapy with lower baseline weight-for-age Z-score (adjusted hazard ratio = 2.5; 95% confidence interval: 1.1–6.1) were significantly associated with high risk of mortality. On the other hand, study participants with a baseline CD4 count above 200 cells/mm3 (adjusted hazard ratio = 0.7; 95% confidence interval: 0.4–0.9) and those participants who had psychosocial support during follow-up (adjusted hazard ratio = 0.03; 95% confidence interval: 0.1–0.7) were significantly associated with less mortality event. Conclusion: Mortality of children on antiretroviral therapy was high. The risk of mortality is increased if the child was underweight at the commencement of antiretroviral therapy, had lower baseline CD4 count, had poor adherence to antiretroviral therapy and had no psychosocial support. Concerned stakeholders should focus on antiretroviral therapy adherence, nutritional interventions, psychological support and early initiation of antiretroviral therapy regardless of their CD4 count to enhance survival of HIV-infected children on antiretroviral therapy.

Abstract
INTRODUCTION Recognizing the predictors of mortality among HIV-infected children will allow for concerted management that can reduce HIV-mortality in Nigeria. METHODOLOGY A retrospective cohort study in children aged 0-15 years, between October 2010 and December 2013, at the Federal Medical Centre, Makurdi, Nigeria. Kaplan-Meier method analysed the cumulative probability of early mortality (EM) occurring at or before 6 months and after 6 months of follow-up (late mortality-LM) on a 12-month antiretroviral therapy (ART). Multivariate Cox proportional regression models were used to test for hazard ratios (HR). RESULTS 368 children were included in the analysis contributing 81 children per 100 child-years to the 12-month ART follow-up. A significant reduction in EM rates was noted at 17.3 deaths per 100 child-years (30 deaths) to LM rates of 3.0 deaths per 100 child-years (10 deaths), p < 0.01. At multivariate analysis, children with a high pretreatment viral load (≥10,000 copies/ml) were found to be at risk of EM (aHR; 18. 089, 95% CI; 2.428-134.77, p=0.005). Having severe immunosuppression at/or before 6 months of ART was the predictor of LM (aHR; 17.28, 95% CI; 3.844-77.700, p ≤ 0.001). CONCLUSIONS Although a lower mortality rate is seen at 12 months of ART in our setting, predictors of HIV mortality are having high pretreatment HIV viral load and severe immunosuppression. While primary prevention of HIV infection is paramount, early identification of these predictors among our HIV-infected children for an early ART initiation can reduce further the mortality in our setting. In addition, measures to ensure a good standard of care and retention in care for a sustained virologic suppression cannot be ignored and are hereby underscored.

Abstract
The objective of the study was to determine predictors of survival among HIV-positive children (<15 years) in Swaziland. A retrospective cohort analysis of medical records for 4 167 children living with HIV who were initiated on antiretroviral therapy (ART) between 2004 and 2008, and followed up until 2014 was conducted in clinical settings at 36 health facilities. The Kaplan Meier Estimator, signed-ranks test, and the Cox proportional hazards regression model were applied to determine survival probabilities, significant difference among stratified survival functions and adjusted hazard ratios respectively. The results reveal that the median survival time for children was 78 months (95% CI: 77-79). Children who were initiated early on ART had higher survival probability over time (HR: 0.35 [95% CI: 0.21-0.57], p < 0.001) compared to those whose ART initiation was delayed. Children within the age group of <1 years had higher hazard (HR = 1.55 [95% CI: 1.16-2.08], p < 0.001) of death than children within the age group of 1-14 years. Children who were nourished had 88% lower hazard of death (HR: 0.12 [95% CI: 0.07-0.19], p < 0.001) than severely malnourished children. The study demonstrates that ART paediatric services are effective in increasing survival among HIV infected children and early initiated children have high survival probability. Active tuberculosis (TB), malnutrition, and delayed ART initiation remain predictors of poor survival among children living with HIV.

Abstract
BACKGROUND AND OBJECTIVES The mortality rate of HIV-infected children can be reversed under highly active antiretroviral therapy (HAART). The impact of HAART on the mortality of HIV-infected children in Cameroon has not been extensively documented. We aimed to measure the mortality rate of HIV-infected children under HAART and to identify predictive factors of mortality. METHODS Retrospective cohort study of 221 children initiated on HAART from 2005 to 2009 and followed-up until 2013. Survival data was analyzed using Kaplan Meier method and Cox regression model to identify independent predictors of child mortality on HAART. RESULTS Overall, 9.9% of children (n=22) died over a follow-up period of 755 child-years (mortality of 2.9 per 100 child-years); 70% of deaths occurred during the first six months of HAART. The probability of survival after four years of treatment was 88.7% (95% CI=[84.2-93.3]). During the multivariate analysis of baseline variables, we observed that the WHO clinical stages III and IV (HR: 3.55 [1.09-13.6] and HR: 7.7 [3.07-31.2]) and age≤1year at HAART initiation were independently associated with death (HR: 2.1 [1.01-5.08]). Neither orphanhood, baseline CD4 count or hemoglobin level nor low nutritional status predicted death in this cohort. CONCLUSION The mortality of children receiving HAART was low after five years of follow-up and it was strongly associated with WHO stages III and IV and a younger age at treatment initiation.

Abstract
BACKGROUND Information on antiretroviral therapy (ART) use in HIV-infected children with severe malnutrition (SM) is lacking. We investigated long-term ART outcomes in this population. METHODS Children enrolled in the TREAT Asia Pediatric HIV Observational Database who had SM (weight-for-height or body mass index-for-age Z score less than -3) at ART initiation were analyzed. Generalized estimating equations were used to investigate poor weight recovery (weight-for-age Z score less than -3) and poor CD4% recovery (CD4% <25), and competing risk regression was used to analyze mortality and toxicity-associated treatment modification. RESULTS Three hundred fifty-five (11.9%) of 2993 children starting ART had SM. Their median weight-for-age Z score increased from -5.6 at ART initiation to -2.3 after 36 months. Not using trimethoprim-sulfamethoxazole prophylaxis at baseline was associated with poor weight recovery [odds ratio: 2.49 vs. using; 95% confidence interval (CI): 1.66-3.74; P < 0.001]. Median CD4% increased from 3.0 at ART initiation to 27.2 after 36 months, and 56 (15.3%) children died during follow-up. More profound SM was associated with poor CD4% recovery (odds ratio: 1.78 for Z score less than -4.5 vs. -3.5 to less than -3.0; 95% CI: 1.08-2.92; P = 0.023) and mortality (hazard ratio: 2.57 for Z score less than -4.5 vs. -3.5 to less than -3.0; 95% CI: 1.24-5.33; P = 0.011). Twenty-two toxicity-associated ART modifications occurred at a rate of 2.4 per 100 patient-years, and rates did not differ by malnutrition severity. CONCLUSION Trimethoprim-sulfamethoxazole prophylaxis is important for the recovery of weight-for-age in severely malnourished children starting ART. The extent of SM does not impede weight-for-age recovery or antiretroviral tolerability, but CD4% response is compromised in children with a very low weight-for-height/body mass index-for-age Z score, which may contribute to their high rate of mortality.

Abstract
We assessed isoniazid preventive therapy (IPT) completion and predictors among HIV-infected children and adults in two HIV clinics in Kinshasa, Democratic Republic of Congo. Between 1 September 2012 and 15 June 2013, 546 children (1-15 years) and 1532 adults (>15 years) were initiated on IPT; 86.6% (408/470) of the children and 88.2% (1129/1280) of the adults with an IPT outcome completed their therapy. Patients on antiretroviral therapy at IPT initiation were more likely to complete IPT.

Abstract
SummaryHighly active antiretroviral therapy has decreased the morbidity and mortality related to HIV infection, including oral opportunistic infections. This paper offers an analysis of the scientific literature on the epidemiological aspects of oral candidiasis in HIV-positive children in the combination antiretroviral therapy era. An electronic databases search was made covering the highly active antiretroviral therapy era (1998 onwards). The terms used were oral lesions, oral candidiasis and their combination with highly active antiretroviral therapy and HIV/AIDS children. The following data were collected from each paper: year and country in which the investigation was conducted, antiretroviral treatment, oral candidiasis prevalence and diagnostic parameters (clinical or microbiological). Prevalence of oral candidiasis varied from 2.9% in American HIV-positive children undergoing highly active antiretroviral therapy to 88% in Chilean HIV-positive children without antiretroviral therapy. With respect to geographical location and antiretroviral treatment, higher oral candidiasis prevalence in HIV-positive children on combination antiretroviral therapy/antiretroviral therapy was reported in African children (79.1%) followed by 45.9% reported in Hindu children. In HIV-positive Chilean children on no antiretroviral therapy, high oral candidiasis prevalence was reported (88%) followed by Nigerian children (80%). Oral candidiasis is still frequent in HIV-positive children in the highly active antiretroviral therapy era irrespective of geographical location, race and use of antiretroviral therapy.

Abstract
BACKGROUND While highly active antiretroviral therapy (HAART) programs have been scaled up across sub-Saharan Africa, no prognostic models for the prediction of mortality risk for children initiating HAART are widely available. Current clinical prediction tools for human immunodeficiency virus (HIV)-infected children are derived from pre-HAART data and therefore cannot predict mortality for children initiating HAART. The purpose of this study was to develop a mortality risk scoring system for HIV-infected children beginning HAART in a resource-deprived setting. METHODS Observational data from HIV-infected children initiating HAART from December 2004 through March 2012 in Kinshasa, Democratic Republic of Congo, were analyzed. Cox proportional hazards models were constructed to assess associations between demographic and clinical characteristics at the time of HAART initiation and mortality. Each child received a model-based risk score predicting mortality after HAART initiation. RESULTS By 31 March 2012, 1010 children had started HAART. One hundred three children (10.2%) died at a median of 5.3 months post-HAART initiation, yielding a mortality rate of 3.4 deaths per 100 child-years. The final mortality prediction model included undernutrition, low CD4 count, HIV symptoms, and low total lymphocyte count. These factors were highly predictive of mortality in the study population (C statistic = 0.79) and performed well when applied to the validation population (C statistic = 0.77). CONCLUSIONS Mortality among children starting HAART in resource-deprived settings can be predicted using a simple scoring system incorporating several readily available factors. Identifying predictors of mortality will help clinicians target modifiable risk factors, such as undernutrition, which are not directly addressed by HAART.

Abstract
INTRODUCTION Residents of Zambézia Province, Mozambique live from rural subsistence farming and fishing. The 2009 provincial HIV prevalence for adults 15-49 years was 12.6%, higher among women (15.3%) than men (8.9%). We reviewed clinical data to assess outcomes for HIV-infected children on combination antiretroviral therapy (cART) in a highly resource-limited setting. METHODS We studied rates of 2-year mortality and loss to follow-up (LTFU) for children <15 years of age initiating cART between June 2006-July 2011 in 10 rural districts. National guidelines define LTFU as >60 days following last-scheduled medication pickup. Kaplan-Meier estimates to compute mortality assumed non-informative censoring. Cumulative LTFU incidence calculations treated death as a competing risk. RESULTS Of 753 children, 29.0% (95% CI: 24.5, 33.2) were confirmed dead by 2 years and 39.0% (95% CI: 34.8, 42.9) were LTFU with unknown clinical outcomes. The cohort mortality rate was 8.4% (95% CI: 6.3, 10.4) after 90 days on cART and 19.2% (95% CI: 16.0, 22.3) after 365 days. Higher hemoglobin at cART initiation was associated with being alive and on cART at 2 years (alive: 9.3 g/dL vs. dead or LTFU: 8.3-8.4 g/dL, p<0.01). Cotrimoxazole use within 90 days of ART initiation was associated with improved 2-year outcomes Treatment was initiated late (WHO stage III/IV) among 48% of the children with WHO stage recorded in their records. Marked heterogeneity in outcomes by district was noted (p<0.001). CONCLUSIONS We found poor clinical and programmatic outcomes among children taking cART in rural Mozambique. Expanded testing, early infant diagnosis, counseling/support services, case finding, and outreach are insufficiently implemented. Our quality improvement efforts seek to better link pregnancy and HIV services, expand coverage and timeliness of infant diagnosis and treatment, and increase follow-up and adherence.

Abstract
The purpose of this review was to outline the interaction between HIV and noncommunicable diseases affecting the gastrointestinal (GI) tract, liver, and nutritional disorders in low- and middle-income countries (LMICs), and to identify research priorities. Noncommunicable GI tract disorders are only moderately influenced by HIV, and peptic ulceration is actually less common. However, the impact of HIV on GI cancers needs further investigation. HIV interacts strongly with environmental enteropathy, exacerbating malabsorption of nutrients and drugs. HIV has 2 major effects on noncommunicable liver disease: drug-induced liver injury and nonalcoholic fatty liver disease (particularly in persons of African genetic descent). The effect of HIV on nutrition was one of the first markers of the epidemic in the 1980s, and HIV continues to have major nutritional consequences. Childhood malnutrition and HIV frequently coexist in some regions, for example, southern Africa, resulting in powerful negative interactions with poorer responses to standard nutritional rehabilitation. HIV and nutritional care need to be better integrated, but many questions on how best to do this remain unanswered. Across the spectrum of GI, hepatic, and nutritional disorders in HIV infection, there is increasing evidence that the microbiome may play an important role in disease pathogenesis, but work in this area, especially in low- and middle-income countries, is in its infancy.

Abstract
Background The introduction of antiretroviral therapy in 1996 improved the longevity and wellbeing of peoples living with HIV in the industrialized world including children. This survival benefit of antiretroviral therapy (ART) in reducing HIV related deaths has been well studied in the developed world. In resource-poor settings, where such treatment was started recently, there is inadequate information about impact of ART on the survival of patients especially in children. So, this study aims to investigate predictors of mortality of children on ART. Therefore, the objective of this study was to identify predictors of mortality among children on HAART. Methods A retrospective cohort study was conducted on 432 children who initiated antiretroviral therapy from June 2006 to June 2011 at pediatrics ART clinic in Mekelle Hospital, Northern-Ethiopia. Data were extracted from electronic and paper based medical records database and analyzed using Kaplan Meier survival and Cox proportional hazard model to identify independent predictors of children’s mortality on ART. Results The total time contributed by the study participants were 14,235 child-months with median follow up of 36 months. The mortality rate of this cohort was 1.40 deaths per 1000 child-months or 16.85 deaths per 1000 child-years. Age less than 18 months [ Adj.HR (95% CI) = (4.39(1.15-17.41)], CD4 percentage <10 [Adj.HR (95% CI) = 2.98(1.12-7.94)], WHO clinical stage (III&IV) [Adj.HR (95% CI) = 4.457(1.01-19.66)], chronic diarrhea[Adj.HR (95% CI) = 4.637(1.50-14.31)] and hemoglobin < 8 g/dl[Adj.HR (95% CI) = 3.77(1.29-10.98)] all at baseline were significantly and independently associated with survival of children on ART. Conclusions Mortality of children on ART was low and factors that affect mortality of children on ART were age less than 18 months, lower CD4 percentage, advanced WHO clinical stage (III&IV), presence of chronic diarrhea and lower hemoglobin level all at baseline. The high early mortality rate would support the value of an earlier treatment start before development of signs of immunodeficiency syndrome despite the method of HIV diagnosis and WHO stage.

Abstract
OBJECTIVE Although antiretroviral treatment (ART) has reduced the incidence of HIV-related opportunistic infections among children living with HIV, access to ART remains limited for children, especially in resource-limited settings. This paper reviews current knowledge on the contribution of opportunistic infections and common childhood illnesses to morbidity and mortality in children living with HIV, highlights interventions known to improve the health of children, and identifies research gaps for further exploration. DESIGN AND METHODS Literature review of peer-reviewed articles and abstracts combined with expert opinion and operational experience. RESULTS Morbidity and mortality due to opportunistic infections has decreased in both developed and resource-limited countries. However, the burden of HIV-related infections remains high, especially in sub-Saharan Africa, where the majority of HIV-infected children live. Limitations in diagnostic capacity in resource-limited settings have resulted in a relative paucity of data on opportunistic infections in children. Additionally, the reliance on clinical diagnosis means that opportunistic infections are often confused with common childhood illnesseswhich also contribute to excess morbidity and mortality in these children. Although several preventive interventions have been shown to decrease opportunistic infection-related mortality, implementation of many of these interventions remains inconsistent. CONCLUSIONS In order to reduce opportunistic infection-related mortality, early ART must be expanded, training for front-line clinicians must be improved, and additional research is needed to improve screening and diagnostic algorithms.

Abstract
There is consensus on the benefits for all infants of exclusive breastfeeding for 6 months and introduction of appropriate complementary foods at 6 months, followed by continued breastfeeding. However, guidelines on infant and young child feeding (IYCF) for HIV-positive mothers have changed continually since 2000. This article explores issues and evidence related to IYCF for the prevention and care of paediatric HIV in resource-limited settings in light of new HIV treatment guidelines, implementation challenges and knowledge gaps.In 2010 the impact of antiretroviral drugs (ARVs) on reducing the risk of mother-to-child transmission of HIV moved WHO to urge countries to endorse either avoidance of all breastfeeding or exclusive breastfeeding for the first 6 months while taking ARVs, depending on which strategy could give their infants the greatest chance of HIV-free survival. Implementation of the 2010 recommendations is challenged by lack of healthcare provider training, weak clinic-community linkages to support mother/infant pairs and lack of national monitoring and reporting on infant feeding indicators.More evidence is needed to inform prevention and treatment of malnutrition among HIV-exposed and HIV-infected children. Knowledge gaps include the effects of prolonged ARV exposure, the cause of HIV-associated growth faltering, the effects of early infant testing on continuation of breastfeeding and specific nutrition interventions needed for HIV-infected children.Significant progress has been made toward keeping mothers alive and reducing paediatric HIV infection, but sustained political, financial and scientific commitment are required to ensure meaningful interventions to eliminate postnatal transmission and meet the nutritional needs of HIV-exposed and HIV-infected children.

Abstract
To explore immunologic risk factors for death within 90 days of highly active antiretroviral therapy (HAART) initiation, CD4(+) and CD8(+) T cell subsets were measured by flow cytometry and characterized by logistic regression in 149 Zambian children between 9 months and 10 years of age enrolled in a prospective, observational study of the impact of HAART on measles immunity. Of 21 children who died during follow-up, 17 (81%) had known dates of death and 16 (76%) died within 90 days of initiating HAART. Young age and low weight-for-age z-scores were associated with increased risks of mortality within 90 days of starting HAART, whereas CD4(+) T cell percentage was not associated with mortality. After adjusting for these factors, each 10% increase in CD8(+) effector T cells increased the odds of overall mortality [OR=1.43 (95% CI: 1.08, 1.90)] and was marginally associated with early mortality [OR=1.29 (95% CI: 0.97, 1.72)]. Conversely, each 10% increase in CD4(+) central memory T cells decreased the odds of overall [OR=0.06 (95% CI: 0.01, 0.59)] and early mortality [OR=0.09 (95% CI: 0.01, 0.97)]. Logistic regression prediction models demonstrated areas under the receiver-operator characteristic curves of ≥85% for early and overall mortality, with bootstrapped sensitivities of 82-85% upon validation, supporting the predictive accuracy of the models. CD4(+) and CD8(+) T cell subsets may be more accurate predictors of early mortality than CD4(+) T cell percentages and could be used to identify children who would benefit from more frequent clinical monitoring after initiating HAART.

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
Late presentation is common among African HIV-1-infected infants. Incidence and correlates of mortality were examined in 99 infants with HIV-1 diagnosis by 5 months of age. Twelve-month survival was 66.8% (95% confidence interval: 55.9-75.6%). World Health Organization stage 3 or 4, underweight, wasting, microcephaly, low hemoglobin, pneumonia and gastroenteritis predicted mortality. Early HIV-1 diagnosis with antiretroviral therapy before symptomatic disease is critical for infant survival.

Abstract
OBJECTIVE To identify baseline demographic and clinical risk factors associated with poor CD4 and weight response after initiation of antiretroviral therapy (ART) in a cohort of human immunodeficiency virus (HIV)-infected children in KwaZulu-Natal, South Africa. METHODS We performed a retrospective cohort study of 674 children initiating antiretroviral therapy at McCord and St. Mary's hospitals in KwaZulu-Natal, South Africa, from August 2003 to December 2008. We extracted data from paper charts and electronic medical records to assess risk factors associated with CD4 and weight response using logistic regression. RESULTS From the initial cohort of 901 children <10 years old initiating ART between August 2003 and December 2008, we analyzed 674 children with complete baseline data. Viral suppression rates (<400 copies/ml) were 84% after six months of therapy and 88% after 12 months of therapy. Seventy-three percent of children achieved CD4 recovery after six months and 89% after 12 months. Weight-for-age Z-score (WAZ) improvements were seen in 58% of children after six months of ART and 64% after 12 months. After six months of ART, lower baseline hemoglobin (p = 0.037), presence of chronic diarrhea (p = 0.007), and virologic failure (p = 0.046) were all associated with poor CD4 recovery by multivariate logistic regression. After 12 months of ART, poor CD4 recovery was associated with higher baseline CD4% (p = 0.005), chronic diarrhea (p = 0.02), and virologic failure (p<0.001). Age less than 3 years at ART initiation (p = 0.0003), higher baseline CD4% (p<0.001), and higher baseline WAZ (p<0.001) were all associated with poor WAZ improvements after 6 months by multivariate logistic regression. CONCLUSION The presence of chronic diarrhea at baseline, independent of nutritional status and viral response, predicts poor CD4 recovery. Age at initiation of ART is an important factor in early WAZ response to ART, while viral suppression strongly predicts CD4 recovery but not WAZ improvement.

Abstract
This retrospective observational study of 140 HIV-infected children with uncomplicated malnutrition in urban Malawi tested the hypothesis that initiation of antiretroviral therapy (ART) within 21 days of outpatient therapeutic feeding (prompt ART) improved clinical outcomes. Children receiving prompt ART were more likely to recover nutritionally (86% vs. 60%, P < 0.01) and had higher rates of weight gain (3.6 vs. 1.6 g/k/day; P = 0.02). Logistic regression modeling found prompt ART was associated with increased likelihood of nutritional recovery (odds ratio: 5.4, 95% confidence interval: 2.0 to 14.5). This suggests that prompt ART is associated with improved outcomes in HIV-infected Malawian children with uncomplicated malnutrition.

Challenges in the Management of HIV-Infected Malnourished Children in Sub-Saharan Africa. AIDS Res Treat 2012; 2012:790786.

Abstract
Infection with HIV, and oftentimes coinfection with TB, complicates the care of severely malnourished children in sub-Saharan Africa. These superimposed infections challenge clinicians faced with a population of malnourished children for whose care evidence-based guidelines have not kept up. Even as the care of HIV-uninfected malnourished children has improved dramatically with the advent of community-based care and even as there are hopeful signs that the HIV epidemic may be stabilizing or ameliorating, significant gaps remain in the care of malnourished children with HIV. Here we summarize what is currently known, what remains unknown, and what remains challenging about how to treat severely malnourished children with HIV and TB.

Abstract
Despite the need for HIV-positive children to adhere effectively to antiretroviral treatment (ART), a guiding theory for pediatric ART in resource-limited settings is still missing. Understanding factors that influence pediatric ART adherence is critical to developing adequate strategies. In-depth qualitative interviews were undertaken in Kinshasa, Democratic Republic of the Congo, with 20 sets of HIV disclosed and nondisclosed children along with respective caregivers to better characterize barriers, facilitators, and adherence experiences in children taking ART. Commonly cited barriers included lack of food or nutritional support, lack of assistance or supervision for children, lack of assistance for caregivers, and being unable to remember to take medicines on a consistent basis. Facilitators included having a strong caregiver-child relationship and support system along with strategies for maintaining adherence. Similar themes arose within the child-caregiver sets, but were often characterized differently between the two. Children who were aware of their HIV status displayed fewer instances of frustration and conflict concerning taking medicines and within the child-caregiver relationship. Continued study on pediatric ART adherence should account for differing perspectives of children and caregivers, as well as between status disclosed and nondisclosed children. Areas of future intervention should focus on child-caregiver relationships, disclosure of HIV status, and available nutritional and psychosocial support for children and their caregivers.

PLoS One 2011; 6:e22706. [PMID: 21829487 PMCID: PMC3146475 DOI: 10.1371/journal.pone.0022706] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2011] [Accepted: 07/05/2011] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVE To identify demographic and clinical risk factors associated with mortality after initiation of antiretroviral therapy (ART) in a cohort of human immunodeficiency (HIV) infected children in KwaZulu-Natal, South Africa. METHODS We performed a retrospective cohort study of 537 children initiating antiretroviral therapy at McCord Hospital in KwaZulu-Natal, South Africa. Data were extracted from electronic medical records and risk factors associated with mortality were assessed using Cox regression analysis. RESULTS Overall there were 47 deaths from the cohort of 537 children initiating ART with over 991 child-years of follow-up (median 22 months on ART), yielding a mortality rate of 4.7 deaths per 100 child years on ART. Univariate analysis indicated that mortality was significantly associated with lower weight-for-age Z-score (p<0.0001), chronic diarrhea (p = 0.0002), lower hemoglobin (p = 0.002), age <3 years (p = 0.003), and CD4% <10% (p = 0.005). The final multivariable Cox proportional hazards mortality model found age less than 3 years (p = 0.004), CD4 <10% (p = 0.01), chronic diarrhea (p = 0.03), weight-for-age Z-score (<0.0001) and female gender as a covariate varying with time (p = 0.03) all significantly associated with mortality. CONCLUSION In addition to recognized risk factors such as young age and advanced immunosuppression, we found female gender to be significantly associated with mortality in this pediatric ART cohort. Future studies are needed to determine whether intrinsic biologic differences or socio-cultural factors place female children with HIV at increased risk of death following initiation of ART.

Viral load predicts new world health organization stage 3 and 4 events in HIV-infected children receiving highly active antiretroviral therapy, independent of CD4 T lymphocyte value. Clin Infect Dis 2010; 51:1325-33.

Abstract
BACKGROUND Many resource-limited countries rely on clinical and immunological monitoring without routine virological monitoring for human immunodeficiency virus (HIV)-infected children receiving highly active antiretroviral therapy (HAART). We assessed whether HIV load had independent predictive value in the presence of immunological and clinical data for the occurrence of new World Health Organization (WHO) stage 3 or 4 events (hereafter, WHO events) among HIV-infected children receiving HAART in Latin America. METHODS The NISDI (Eunice Kennedy Shriver National Institute of Child Health and Human Development International Site Development Initiative) Pediatric Protocol is an observational cohort study designed to describe HIV-related outcomes among infected children. Eligibility criteria for this analysis included perinatal infection, age <15 years, and continuous HAART for ≥6 months. Cox proportional hazards modeling was used to assess time to new WHO events as a function of immunological status, viral load, hemoglobin level, and potential confounding variables; laboratory tests repeated during the study were treated as time-varying predictors. RESULTS The mean duration of follow-up was 2.5 years; new WHO events occurred in 92 (15.8%) of 584 children. In proportional hazards modeling, most recent viral load >5000 copies/mL was associated with a nearly doubled risk of developing a WHO event (adjusted hazard ratio, 1.81; 95% confidence interval, 1.05-3.11; P = .033), even after adjustment for immunological status defined on the basis of CD4 T lymphocyte value, hemoglobin level, age, and body mass index. CONCLUSIONS Routine virological monitoring using the WHO virological failure threshold of 5000 copies/mL adds independent predictive value to immunological and clinical assessments for identification of children receiving HAART who are at risk for significant HIV-related illness. To provide optimal care, periodic virological monitoring should be considered for all settings that provide HAART to children.

Abstract
BACKGROUND Treating HIV-infected children remains a challenge due to a lack of treatment options, appropriate drug formulations and, in countries with limited resources, insufficient access to diagnostic tests and treatment. OBJECTIVE To summarize current data concerning new opportunities to improve the treatment of HIV-infected children. METHODS This review includes data from the most recently published peer-reviewed publications, guidelines or presentations at international meetings concerning new ways to treat HIV-infected children. RESULTS/CONCLUSIONS New WHO guidelines recommend starting combination antiretroviral treatment in all infants aged < 1 year. Although this is common practice in some high-income countries, implementation of these recommendations in countries with limited resources is still a challenge. There is still an important gap between the availability of licensed drugs in children compared with adults. There remains a need for further pharmacokinetic studies, and for more pediatric formulations of antiretroviral drugs with improved palatability.

Abstract
OBJECTIVES To determine predictors of mortality in children on anti-retroviral therapy (ART) who attended the Paediatric HIV Clinic at Kamuzu Central Hospital in Lilongwe, Malawi. METHODS Retrospective case cohort study by chart review of children who had started ART between October 2004 and May 2006. Bivariable and multivariable analysis were performed with and without defaulters to evaluate associations according to vital status and to identify independent predictors of mortality. RESULTS Forty-one of 258 children (15.9%) were deceased, 185 (71.7%) were alive, and 32 (12.4%) had defaulted: 51% were female, 7% were under 18 months, 26% were 18 months to 5 years, and 54% were >5 years of age. Most were WHO stage III or IV (56% and 37%, respectively). On multivariate analysis, factors most strongly associated with mortality and defaulting were age <18 months [hazards ratio (HR) 2.11 (95% CI 1.0-4.51)] and WHO stage IV [HR 2.00 (95% CI 1.07-3.76)]. CONCLUSIONS To improve outcomes of HIV-positive children, they must be identified and treated early, specifically children under 18 months of age. Access to infant diagnostic procedures must be improved to allow effective initiation of ART in infants at higher risk of death.

Abstract
Evaluation of: Violari A, Paed FC, Cotton MF et al.: Early antiretroviral therapy and mortality among HIV-infected infants. N. Engl. J. Med. 359(21), 2233-2244 (2008). Violari and her colleagues report the first randomized, open-label trial showing that early diagnosis and treatment with antiretroviral therapy decreases mortality and HIV progression in HIV-infected infants. The reality of implementing this recommendation into clinical care is challenging in resource-poor countries. Support for earlier diagnosis and access to antiretrovirals is improving, but access to HAART for all HIV-infected infants and children is often lacking. A change in care systems advocating early institution of antiretroviral therapy for all infants in these developing countries is clearly needed.
