Abstract
BACKGROUND South Africa (SA) has the greatest HIV prevalence in the world, with rates as high as 40% among pregnant women. Depression is a robust predictor of nonadherence to antiretroviral therapy (ART) and engagement in HIV care; perinatal depression may affect upwards of 47% of women in SA. Evidence-based, scalable approaches for depression treatment and ART adherence in this setting are lacking. METHOD Twenty-three pregnant women with HIV (WWH), ages 18-45 and receiving ART, were randomized to a psychosocial depression and adherence intervention or treatment as usual (TAU) to evaluate intervention feasibility, acceptability, and preliminary effect on depressive symptoms and ART adherence. Assessments were conducted pre-, immediately post-, and 3 months post-treatment, and included a qualitative exit interview. RESULTS Most (67.6%) eligible individuals enrolled; 71% completed at least 75% of sessions. Compared to TAU, intervention participants had significantly greater improvements in depressive symptoms at post-treatment, β = - 11.1, t(24) = - 3.1, p < 0.005, 95% CI [- 18.41, - 3.83], and 3 months, β = - 13.8, t(24) = - 3.3, p < 0.005, 95% CI [- 22.50, - 5.17]. No significant differences in ART adherence, social support, or stigma were found. Qualitatively, perceived improvements in social support, self-esteem, and problem-solving adherence barriers emerged as key benefits of the intervention; additional sessions were desired. CONCLUSION A combined depression and ART adherence intervention appears feasible and acceptable, and demonstrated preliminary evidence of efficacy in a high-need population. Additional research is needed to confirm efficacy and identify dissemination strategies to optimize the health of WWH and their children. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT03069417. Protocol available at https://clinicaltrials.gov/ct2/show/NCT03069417.

Kownaklai J, Graham M, Hayter M. Pregnancy decision making among Thai women living with HIV: a grounded theory study: Pregnancy decision making amongst Thai women living with HIV. Midwifery 2022; 115:103490. [PMID: 36155391 DOI: 10.1016/j.midw.2022.103490] [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: 04/25/2022] [Revised: 09/12/2022] [Accepted: 09/14/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVE this qualitative research study aims to understand and generate a model of the pregnancy decision-making process in Thai women living with HIV. METHOD the constructivist grounded theory of Charmaz was chosen as the research approach and method to generate a pregnancy decision-making process which is shaped and constructed by personal and social processes. DATA COLLECTION was undertaken in antenatal clinics (ANCs) at two provincial hospitals located in the Northeast of Thailand. In-depth semi-structured interviews were conducted with 15 HIV positive pregnant women. Data analysis involved open coding, making-memos and using the constant comparative method to develop a grounded theory substantive model of HIV pregnancy decision making. FINDINGS the substantive model consists of 6 categories; 1) concealing HIV positive status from partner; 2) desire to have a child; 3) becoming pregnant; 4) keeping or terminating pregnancy; 5) accepting the decision; and 6) adapting to the decision. This research finds that the main concerns women living with HIV have in deciding to have a child are balancing fear, concealing HIV status and the information that they have in each decision making step. Based on the research findings, a unique process of decision making has been found amongst these women that relates to personal and Thai social beliefs. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE the concept illustrates not only the process of decision making but also highlights the main stages, issues and concerns of women living with HIV wanting a child. This study recommends that health care providers need to pay more attention to counselling women and couples living with HIV by giving sufficient contraceptive information to prevent unplanned and unwanted pregnancy, to support and guide the women who want and plan for pregnancy, in advance of this happening, and helping women to deal with HIV disclosure issues related to morality and the rights of couples. Moreover, respect and support must be accorded to HIV positive women about their right to have a child if they choose to do so.

Abstract
Define anemia is the low concentration in the amount of hemoglobin according to age, sex and trimester pregnancy. The pregnant has three trimesters and has an exceptional hemoglobin range in every trimester. The pregnant has 124-135 g/dl in the 1st trimester, 110-117 g/dl in the 2nd trimester and 106-109 g/dl in the 3rd trimester. Many pregnant females had been found with anemia because of a low level of Iron. This leads to megaloblastic anemia because of iron deficiency anemia and B12 Vitamin, diet, gastrectomy, malabsorption, blood loss and physiological demand (pregnancy infancy and adolescence). The blood consists of Hemoglobin (Heam + globin) Heam and Iron protoporphyrin ring. Globin is the type of protein with a specific length of amino acid and a specific type of A, maybe 2 Alpha 2 Beta called A1 or 2 Alpha and 2 Bata called A2 or 2Alpha and Gamma called F Fetal. The production of hemoglobin depends on the previously mentioned factors. In this study, we focused on some factors associated with the amount of blood and how these factors affected anemia, which is the most important in Iron treatments, with considering other factors such as food, diversity, Economic situation, social status, number of the fetus, and number of pregnancies. Statistical analysis was used to detect the effect factors of anemia in pregnant. This study refers to 23.2% of anemia because of Iron deficiency during pregnancy. So, treatment of Iron deficiency reduces anemia during pregnancy time.

Abstract
Background Fewer infants are infected with HIV through mother-to-child transmission, making HIV-exposed but uninfected (HEU) infants a growing population. HIV-exposure seems to affect immunology, early growth and development, and is associated with higher morbidity and mortality rates. Currently, there is a lack of information regarding the clinical effects of HIV-exposure during the neonatal period. Objectives To identify a possible difference in mortality and common neonatal morbidities in HEU neonates compared to HIV-unexposed neonates. Methods This was a retrospective, descriptive study of all neonates admitted to the neonatal unit at Charlotte Maxeke Johannesburg Academic Hospital between 1 January 2017 and 31 December 2018. HEU neonates were compared to HIV-unexposed neonates. Results There were 3236 neonates included, where 855 neonates were HEU. The HEU neonates had significantly lower birth weight and gestational age. The HEU neonates had higher rates of neonatal sepsis (19.8% vs 14.2%, OR 1.49, p < 0.001), specifically for late onset sepsis, and required more respiratory support. NCPAP and invasive ventilation was more common in the HEU group (36.3% vs 31.3% required NCPAP, p = 0.008, and 20.1% vs 15,0% required invasive ventilation, p < 0.001). Chronic lung disease was more common among HIV-exposed neonates (12.2% vs 8.7%, OR 1.46, p = 0.003). The difference in mortality rates between the study groups was not significant (10.8% of HEU neonates and 13.3% of HIV-unexposed). Conclusions HEU neonates had higher rates of neonatal sepsis, particularly late-onset sepsis, required more respiratory support and had higher rates of chronic lung disease. Mortality of HEU neonates was not different HIV-unexposed neonates.

Abstract
BACKGROUND The life expectancy of people living with HIV (PLWH) remains shorter than that of the general population, despite significant improvement in the recent years. Mortality in HIV-infected individuals may be associated with a higher viral load at of diagnosis, a lower CD4 count, or clinical variables such as sex or route of transmission. This article investigated the role of the HLA-B*5701 varian on mortality among PLWH. METHODS Material for the analysis consist of the data of 2,393 patients for whom the HLA-B*57 variant was known. Those patients were followed under the care of the Infectious Diseases Hospital in Warsaw (n = 1555) and the Clinic of Acquired Immunodeficiency of the Pomeranian Medical University in Szczecin (n = 838). Factors such as age, gender, date of HIV diagnosis, route of transmission, date of death, baseline HIV viral load and baseline CD4 counts, were collected, and end-point cross-sectional analyses were marked at 60, 120, 180 and 240 month of observation. RESULTS HLA-B*5701 allele was found in 133 (5.5%) analyzed cases. Median age was notably higher for HLA-B*5701 positive patients [32.7 (28.3-41.3) vs. 31.6 (26.8-38.3)years p = 0.02]. HLA-B*5701 was associated with lower baseline viral load [4.21 (3.5-4.8) vs. 4.79 (4.2-5.3)log copies/ml p<0.001] and higher CD4count [448 (294.5-662) vs. 352 (176-514) cells/μl p<0.001]. There were no association between HLA-B*5701 and survival for any given end-point. Higher mortality was associated to male gender, intravenous drug users, lower CD4 count at baseline and higher baseline viral load. CONCLUSIONS In our study, the presence of HLA-B*5701 allel was not associated with mortality rate of HIV infected patients, irrespective of being associated with both higher baseline CD4 + cell count and lower baseline HIV viral load.

Abstract
The objective of this study was to determine and compare anemia and iron-deficiency anemia (IDA) rates in young Kenyan children who are HIV infected (HI), HIV exposed, uninfected (HEU), and HIV unexposed (HU). Questionnaires, anthropometrics, and blood samples were collected from HI, HEU, and HU aged 18 to 36 months. Descriptive statistics, Fisher's exact tests, and linear regression were used for analysis. Of 137 total participants, HI (n = 18), HEU (n = 70), and HU (n = 49), 61.1%, 53.6%, and 36.7%, respectively, were anemic, with mean hemoglobin levels highest in HU (P = .006). After adjusting for covariates, HI (β = -9.6, 95% CI:-17.3 to -2.0) and HEU (β = -7.4, 95% CI: -12.9 to -1.9) had lower hemoglobin levels compared with HU. The proportion of children with IDA did not differ significantly across groups (P = .08). HEU have rates of anemia and IDA similar to HI. Anemia risk is generally higher in HEU than HU, even after adjusting for covariates.

Abstract
BACKGROUND Pediatric inpatient mortality rates are as high as 11% in parts of sub-Saharan Africa. Unscheduled clinic visits also burden children in sub-Saharan Africa. Our objective was to identify factors associated with hospital admissions and unscheduled clinic visits among Tanzanian children < 24 months of age. METHODS We conducted a secondary analysis of 2 trials conducted in Dar es Salaam, Tanzania. We performed univariate and Poisson multivariable regression analyses to identify factors associated with hospital admissions and unscheduled clinic visits. RESULTS Of 4784 children < 24 months of age, 293 (6.1%) were hospitalized at least once and 1308 (27.3%) had ≥ 1 unscheduled clinic visit. Infants and children who were exposed to but HIV-negative had increased risk of hospital admission [adjusted risk ratios (aRR): 3.67; 95% CI: 2.45-5.50; P < 0.001] compared with HIV-unexposed children. Those who were HIV-positive had even higher risk of hospital admission compared with those not exposed to HIV (aRR: 10.87; 95% CI: 7.01-16.89; P < 0.001). Birth weight and breast-feeding status were not associated with increased risk of hospital admission. Children with Apgar scores < 7 (aRR: 1.32; 95% CI: 1.03-1.69; P = 0.001), not exclusively breast-fed up to 6 months of age (aRR: 1.34; 95% CI: 1.12-1.60; P = 0.001), and who were HIV-exposed and HIV-negative (aRR: 2.35; 95% CI: 2.08-2.66; P < 0.001) or HIV-positive (aRR: 3.02; 95% CI: 2.52-3.61; P < 0.001) had higher risk of unscheduled clinic visits. CONCLUSIONS Exposure to HIV and being HIV-positive were associated with the greatest risk for hospital admission and unplanned clinic visits among infants and children in Tanzania. Targeting these vulnerable populations in interventional studies may reduce morbidity.

Abstract
BACKGROUND Depression is a robust predictor of nonadherence to antiretroviral (ARV) therapy, which is essential to prevention of mother-to-child transmission (PMTCT). Women in resource-limited settings face additional barriers to PMTCT adherence. Although structural barriers may be minimized by social support, depression and stigma may impede access to this support. PURPOSE To better understand modifiable factors that contribute to PMTCT adherence and inform intervention development. METHODS We tested an ARV adherence model using data from 200 pregnant women enrolled in PMTCT (median age 28), who completed a third-trimester interview. Adherence scores were created using principal components analysis based on four questions assessing 30-day adherence. We used path analysis to assess (i) depression and stigma as predictors of social support and then (ii) the combined associations of depression, stigma, social support, and structural barriers with adherence. RESULTS Elevated depressive symptoms were directly associated with significantly lower adherence (est = -8.60, 95% confidence interval [-15.02, -2.18], p < .01). Individuals with increased stigma and depression were significantly less likely to utilize social support (p < .01, for both), and higher social support was associated with increased adherence (est = 7.42, 95% confidence interval [2.29, 12.58], p < .01). Structural barriers, defined by income (p = .55) and time spent traveling to clinic (p = .31), did not predict adherence. CONCLUSIONS Depression and social support may play an important role in adherence to PMTCT care. Pregnant women living with HIV with elevated depressive symptoms and high levels of stigma may suffer from low social support. In PMTCT programs, maximizing adherence may require effective identification and treatment of depression and stigma, as well as enhancing social support.

Abstract
BACKGROUND An observational study was conducted to examine the role of maternal anthropometry, including mid-arm muscle area (MAMA) and others, as risk factors for low birth weight (LBW), small for gestational age (SGA) and preterm births in human immunodeficiency virus (HIV) infected pregnant women. HIV-positive women (N = 2369), between 12 and 32 weeks gestation were followed through delivery in Tanzania, from 2003 to 2008. Participants were women enrolled in a randomized, double-blind, placebo-controlled, clinical trial who delivered live births. METHODS Binomial regression analysis was used to evaluate the association of maternal nutritional indicators of MAMA, mid-upper arm circumference (MUAC), body mass index (BMI) and maternal weight with LBW, SGA and preterm in multivariate analysis. RESULTS Higher MAMA was associated with a 32% lower risk of LBW compared to lower measurements (RR = 0.68, 95% CI = 0.50-0.94). Similar protective associations were noted for higher BMI (RR = 0.58, 95% CI = 0.42-0.79); maternal weight (RR = 0.50, 95% CI = 0.36-0.69) and MUAC (RR = 0.62, 95% CI = 0.45-0.86). Higher MAMA was also associated with lower risk of SGA (RR = 0.78, 95% CI = 0.68-0.90) and marginally associated with preterm (RR = 0.85, 95% CI = 0.69-1.04). Beneficial associations of MUAC, BMI and maternal weight with SGA and preterm were also observed. CONCLUSION MAMA performs comparably to MUAC, maternal weight and BMI, as a predictor of LBW and SGA in HIV-infected women. The possible role of MAMA and other indicators in screening HIV positive women at risk of adverse pregnancy outcomes should be investigated.

[PMID: 29272387 PMCID: PMC5961296 DOI: 10.1093/cid/cix1102] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2017] [Accepted: 12/19/2017] [Indexed: 11/14/2022] Open
Abstract
Background Human immunodeficiency virus (HIV)-infected pregnant women increasingly receive antiretroviral therapy (ART) to prevent mother-to-child transmission (PMTCT). Studies suggest HIV-exposed uninfected (HEU) children face higher mortality than HIV-unexposed children, but most evidence relates to the pre-ART era, breastfeeding of limited duration, and considerable maternal mortality. Maternal ART and prolonged breastfeeding while on ART may improve survival, although this has not been reliably quantified. Methods Individual data on 19 219 HEU children from 21 PMTCT trials/cohorts undertaken from 1995 to 2015 in Africa and Asia were pooled to estimate the association between 24-month mortality and maternal/infant factors, using random-effects Cox proportional hazards models. Adjusted attributable fractions of risks computed using the predict function in the R package "frailtypack" were used to estimate the relative contribution of risk factors to overall mortality. Results Cumulative incidence of death was 5.5% (95% confidence interval, 5.1-5.9) by age 24 months. Low birth weight (LBW <2500 g, adjusted hazard ratio (aHR, 2.9), no breastfeeding (aHR, 2.5), and maternal death (aHR, 11.1) were significantly associated with increased mortality. Maternal ART (aHR, 0.5) was significantly associated with lower mortality. At the population level, LBW accounted for 16.2% of 24-month mortality, never breastfeeding for 10.8%, mother not receiving ART for 45.6%, and maternal death for 4.3%; combined, these factors explained 63.6% of deaths by age 24 months. Conclusions Survival of HEU children could be substantially improved if public health practices provided all HIV-infected mothers with ART and supported optimal infant feeding and care for LBW neonates.

Front Public Health 2018; 6:139. [PMID: 29868546 PMCID: PMC5962700 DOI: 10.3389/fpubh.2018.00139] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Accepted: 04/23/2018] [Indexed: 12/02/2022] Open
Abstract
Introduction: Early infant diagnosis (EID) of Human Immunodeficiency Virus (HIV) provides an opportunity for follow up of HIV exposed children for early detection of infection and timely access to antiretroviral treatment. We assessed predictors for accessing HIV diagnostic services among under-five children exposed to HIV infection in Muheza district, Tanzania. Methods: A cross sectional facility-based study among mother/guardian-child pairs of HIV exposed children was conducted from June 2015 to June 2016. Using a structured questionnaire, we collected information on HIV status, socio-demographic characteristics and other relevant data. Multiple regression analyses were used to investigate associations of potential predictors of accessing EID services. Results: A total of 576 children with their respective mothers/guardians were recruited. Of the 576 mothers/guardians, 549 (95.3%) were the biological mothers with a median age of 34 years (inter-quartile range: 30–38 years). The median age of the 576 children was 15 months (inter- quartile range: 8.5–38.0 months). A total of 251 (43.6%) children were born to mothers with unknown HIV status at conception. Only 329 (57.1%) children accessed EID between 4 and 6 weeks of age. Children born to mothers with unknown HIV status at conception (AOR = 0.6, 95% CI 0.4–0.8) and those with ages 13–59 months (AOR = 0.4, 95% CI 0.2–0.6) were the significant predictors of missed opportunity to access EID. Children living with the head of household with at least a high education level had higher chances of accessing EID (AOR = 1.8, 95% CI 1.1–3.3). Their chances of accessing EID services was three-fold higher among mothers/guardians with good knowledge of HIV infection prevention of mother to child transmission (AOR = 3.2, 95% CI 2.0–5.2) than those with poor knowledge. Mothers/guardians living in rural areas had poorer knowledge of HIV infection prevention of mother to child transmission (AOR = 0.6, 95% CI 0.4–0.9) than those living in urban areas. Conclusion: Accessibility of EID services among children below 5 years exposed to HIV infection in Muheza is low. These findings stress the need for continued HIV education and outreach services, particularly in rural areas in order to improve maternal and child health.

Cotrimoxazole prophylaxis was associated with enteric commensal bacterial resistance among HIV-exposed infants in a randomized controlled trial, Botswana. J Int AIDS Soc 2018; 20. [PMID: 29119726 PMCID: PMC5810322 DOI: 10.1002/jia2.25021] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Accepted: 10/05/2017] [Indexed: 12/18/2022] Open
Abstract
Introduction Despite declining risk of vertical HIV transmission, prophylactic cotrimoxazole (CTX) remains widely used to reduce morbidity and mortality in the event of HIV infection among exposed infants, with an inherent risk of conferring commensal antimicrobial resistance. Using data from a randomized, placebo‐controlled trial of infant CTX prophylaxis, we sought to quantify emergence of antibiotic resistance. Methods HIV‐exposed uninfected infants enrolled in the Botswana Mpepu study were randomized to prophylactic CTX or placebo between 14 and 34 days of life and continued through 15 months. Stool samples were collected from a subset of participating infants at randomization, three, and six months, and stored at −70°C prior to culture. Specimens that grew Escherichia coli (E. coli) or Klebsiella species (Klebsiella spp.) underwent antibiotic susceptibility testing by Kirby Bauer method using CTX (CTX 1.25/23.75 μg) and Amoxicillin (10 μg) in Mueller Hinton agar. Fisher's exact testing was used to compare prevalence of resistance by randomization arm (CTX/placebo). Results and Discussion A total of 381 stool samples from 220 infants were cultured: 118 at randomization, 151 at three months, and 112 at six‐months. E. coli was isolated from 206 specimens and Klebsiella spp. from 138 specimens. Resistance to CTX was common in both E. coli and Klebsiella spp. at the randomization visit (52.2% and 37.7% respectively) and did not differ by study arm. E. Coli isolates from CTX recipients at three and six months had 94.9% and 84.2% CTX resistance, as compared with 51.4% and 57.5% CTX resistance in isolates from placebo recipients (p=0.01). Klebsiella spp. isolates from CTX recipients had 79.0% and 68.8% CTX resistance at three and six months, as compared with 19.1% and 14.3% in isolates from placebo recipients (p<0.01). Conclusions HIV‐exposed infants randomized to CTX prophylaxis had increased CTX‐resistant commensal gastrointestinal bacteria compared with placebo recipients. Additional research is needed to determine the longer‐term clinical, microbiologic, and public health consequences of antimicrobial resistance selected by infant CTX prophylaxis.

Abstract
OBJECTIVE To assess morbidity and mortality in HIV-exposed uninfected (HEU) children to help guiding appropriate clinical care and effective preventive interventions. DESIGN This is a longitudinal study comparing two cohorts of children; one born to HIV-infected women and the other born to HIV-uninfected women. METHODS We have analyzed prospectively obtained information on nutritional status, morbidity and mortality from 966 HEU and 909 HIV-unexposed infants followed up until their first 18 months of life at a referral health facility in southern Mozambique. Determinants for adverse health outcomes in HEU children were also assessed using multivariate logistic regression. RESULTS Increased incidence of hospital admissions (P = 0.0015), shorter survival in the first 18 months of life (P = 0.0510) and moderate and severe malnutrition (P = 0.0006 and 0.0014, respectively) were observed among HEU children compared with HIV-unexposed children. Incidence of outpatient attendance in HEU children was associated with being men, older age and the mother being on antiretroviral treatment. Among HEU children, those who were never breastfed, or who were weaned or were partially breastfed, had an increased incidence of hospital admissions compared with children who were exclusively breastfed. CONCLUSION Maternal HIV infection has important health consequences in non-HIV-infected children. As the prevalence of HIV-infected pregnant women is maintained and the proportion of HIV-infected children declines because of the scale-up of antiretroviral treatment during pregnancy and breastfeeding, more focus should be given to the health needs of HEU children to ensure that the post-2015 sustainable development goals are met.

Abstract
OBJECTIVE To describe maternal and neonatal morbidity and mortality among women with HIV infection and their infants. METHODS A secondary analysis was undertaken of data obtained in the BAN Study, a trial of postnatal antiretrovirals among pregnant women with HIV infection enrolled in 2004-2010. Mothers and infants had 13 scheduled visits through 48 weeks of follow-up. Serious maternal morbidity and mortality were examined at delivery (n=2791), from delivery to 6 weeks later (n=2369) and from 7 to 48 weeks (n=1980). Neonatal morbidity and mortality were examined (n=2685). RESULTS Of 2791 deliveries, 169 (6.1%) were by cesarean (153 emergency). Compared with women with vaginal delivery, those with cesarean delivery had lower prenatal HIV viral loads (P=0.016) and increased odds of pre-eclampsia/eclampsia (odds ratio [OR] 10.8, 95% CI 4.4-26.8). Women with cesarean delivery also had increased odds of serious infection with 14 days of delivery (OR 3.0, 95% CI 1.3-7.4) and severe anemia (grade 3 or 4) by 6 weeks (OR 6.7, 95% CI 2.3-19.1). Infants born by cesarean had increased odds of a low 5-minute Apgar score (OR 8.1, 95% CI 3.5-18.6) and admission to an intensive care unit (OR 5.4, 95% CI 3.7-7.8). CONCLUSION Odds of serious maternal and neonatal morbidity were higher after cesarean than vaginal delivery, despite lower maternal viral loads.

Abstract
BACKGROUND HIV-exposed uninfected (HEU) children experience increased mortality compared with their HIV-unexposed uninfected (HUU) peers. It is unclear whether HEU children are also at increased risk for undernutrition, a modifiable risk factor for mortality. METHODS We conducted a cross-sectional, population-based survey of children <5 years of age in 5 health districts in Botswana. Linear mixed-effects models were used to assess continuous outcomes, and generalized estimating equations were used to estimate relative risks of stunting, wasting, and underweight between HEU (n = 396) and HUU (n = 1109) children. Secondary analyses examined potential mediation by low birth weight. RESULTS The association between maternal HIV exposure and child stunting varied significantly by child age (P < 0.01). HEU children <1 and ≥2 years of age had 1.85 [95% confidence interval (CI): 1.03 to 3.31; P = 0.04] and 1.41 (95% CI: 1.06 to 1.88; P = 0.02) times the risk of stunting compared with HUU children after multivariate adjustment, respectively. During the period of 1-2 years of age, when breastfeeding cessation occurred among HUU children, HUU children had increased risk of stunting compared with HEU children who were predominantly formula fed (relative risk: 1.56; 95% CI: 1.05 to 2.32; P = 0.03). A mediation analysis estimated that 67% of the excess risk of stunting among HEU children ≥2 years was attributable to low birth weight (P = 0.02). There was no difference in risk of wasting or underweight. CONCLUSION HEU children are at increased risk of stunting compared with their HUU peers; however, interventions to increase birth weight may significantly ameliorate this excess risk. Interventions to support optimal growth during weaning are needed for all breast-fed children.

Abstract
OBJECTIVE Conduct a meta-analysis examining differential all-cause mortality rates between HIV-exposed uninfected (HEU) infants and children as compared with their HIV-unexposed uninfected (HUU) counterparts. DESIGN Meta-analysis summarizing the difference in mortality between HEU and HUU infants and children. Reviewed studies comparing children in the two groups for all-cause mortality, in any setting, from 1994 to 2016 from six databases. METHODS Meta-analyses were done estimating overall mortality comparing the two groups, stratified by duration of follow-up time from birth (0-12, 12-24 and >24 months) and by year enrollment ended in each study: less than 2002 compared with at least 2002, when single-dose nevirapine for prevention of mother-to-child transmission (PMTCT) commenced in low-income and middle-income countries. RESULTS Included 22 studies, for a total of 29 212 study participants [n = 8840 (30.3%) HEU; n = 20 372 (37.7%) HUU]. Random effects models showed HEU had a more than 70% increased risk of mortality vs. HUU. Stratifying by age showed that HEU vs. HUU had a significant 60-70% increased risk of death at every age strata. There was a significant 70% increase in the risk of mortality between groups before the implementation of PMTCT, which remained after 2002 [risk ratio: 1.46; 95% confidence interval (CI): 1.14-1.87], when the availability of PMTCT services was widespread, suggesting that prenatal antiretroviral therapy, and healthier mothers, does not fully eliminate this increased risk in mortality. CONCLUSION We show a consistent increase risk of mortality for HEU vs. HUU infants and children. Longitudinal research is needed to elucidate underlying mechanisms, such as maternal and infant health status and breast feeding practices, which may help explain these differences in mortality.

Abstract
HIV-exposed uninfected (HEU) infants experience increased overall mortality from infectious causes when compared to HIV-unexposed uninfected (HU) infants. This is the case in both the resource-rich and resource-limited settings. Here, we explore the concept that specific types of infectious diseases that are more common among HEU infants could provide clues as to the potential underlying immunological abnormalities. The most commonly reported infections in HEU vs. HU infants are caused by encapsulated bacteria, suggesting the existence of a less effective humoral (antibody, complement) immune response. Decreased transplacental transfer of protective maternal antibodies has consistently been observed among HEU newborns, suggesting that this may indeed be one of the key drivers of their susceptibility to infections with encapsulated bacteria. Reassuringly, HEU humoral response to vaccination appears to be well conserved. While there appears to be an increase in overall incidence of acute viral infections, no specific pattern of acute viral infections has emerged; and although there is evidence of increased chronic viral infection from perinatal transmission of hepatitis C and cytomegalovirus, no data exist to suggest an increase in adverse outcomes. Thus, no firm conclusions about antiviral effector mechanisms can be drawn. However, the most unusual of reported infections among the HEU have been opportunistic infections, suggesting the possibility of underlying defects in CD4 helper T cells and overall immune regulatory function. This may relate to the observation that the immunological profile of HEUs indicates a more activated T cell profile as well as a more inflammatory innate immune response. However, both of these observations appear transient, marked in early infancy, but no longer evident later in life. The causes of these early-life changes in immune profiles are likely multifactorial and may be related to in utero exposure to HIV, but also to increased environmental exposure to pathogens from sicker household contacts, in utero and postnatal antiretroviral drug exposure, and, in certain circumstances, differences in mode of feeding. The relative importance of each of these factors will be important to delineate in an attempt to identify those HEU at highest risk of adverse outcomes for targeted interventions.

Abstract
More than 1 million HIV-exposed, uninfected infants are born annually to HIV-positive mothers worldwide. This growing population of infants experiences twice the mortality of HIV-unexposed infants. We found that although there were very few differences seen in the microbiomes of mothers with and without HIV infection, maternal HIV infection was associated with changes in the microbiome of HIV-exposed, uninfected infants. Furthermore, we observed that human breast milk oligosaccharides were associated with bacterial species in the infant microbiome. The disruption of the infant's microbiome associated with maternal HIV infection may contribute to the increased morbidity and mortality of HIV-exposed, uninfected infants.

Abstract
BACKGROUND Delays in testing HIV-exposed infants and obtaining results in resource-limited settings contribute to delays for initiating antiretroviral therapy (ART) in infants. To overcome this challenge, Rwanda expanded its national mobile and Internet-based HIV/AIDS informatics system, called TRACnet, to include HIV polymerase chain reaction (PCR) results in 2010. This study was performed to evaluate the impact of TRACnet technology on the time to delivery of test results and the subsequent initiation of ART in HIV-infected infants. METHODS A retrospective cohort study was conducted on 380 infants who initiated ART in 190 health facilities in Rwanda from March 2010 to June 2013. Program data collected by the TRACnet system were extracted and analyzed. RESULTS Since the introduction of TRACnet for processing PCR results, the time to receive results has significantly decreased from a median of 144 days [interquartile range (IQR): 121-197 days] to 23 days (IQR: 17-43 days). The number of days between PCR sampling and health facility receipt of results decreased substantially from a median of 90 days (IQR: 83-158 days) to 5 days (IQR: 2-8 days). After receiving PCR results at a health facility, it takes a median of 44 days (IQR: 32-77 days) before ART initiation. Result turnaround time was significantly associated with time to initiating ART (P < 0.001). An increased number of staff trained for HIV care and treatment was also significantly associated with decreased time to ART initiation (P = 0.004). CONCLUSIONS The use of mobile technology for communication of HIV PCR results, coupled with well-trained and skilled personnel, can reduce delays in communicating results to providers. Such reductions may improve timely ART initiation in resource-limited settings.

Abstract
OBJECTIVE With increasing maternal antiretroviral treatment (ART), the number of children newly infected with HIV has declined. However, the possible increased mortality in the large number of HIV-exposed, uninfected (HEU) children may be of concern. We quantified mortality risks among HEU children and reviewed associated factors. METHODS Systematic search of electronic databases (PubMed, Scopus). We included all studies reporting mortality of HEU children to age 60 months and associated factors. Relative risk of mortality between HEU and HIV-unexposed, uninfected (HUU) children was extracted where relevant. Inverse variance methods were used to adjust for study size. Random-effects models were fitted to obtain pooled estimates. RESULTS A total of 14 studies were included in the meta-analysis and 13 in the review of associated factors. The pooled cumulative mortality in HEU children was 5.5% (95% CI: 4.0-7.2; I(2) = 94%) at 12 months (11 studies) and 11.0% (95% CI: 7.6-15.0; I(2) = 93%) at 24 months (four studies). The pooled risk ratios for the mortality in HEU children compared to HUU children in the same setting were 1.9 (95% CI: 0.9-3.8; I(2) = 93%) at 12 months (four studies) and 2.4 (95% CI: 1.1-5.1; I(2) = 93%) at 24 months (three studies). CONCLUSION Compared to HUU children, mortality risk in HEU children was about double at both age points, although the association was not statistically significant at 12 months. Interpretation of the pooled estimates is confounded by considerable heterogeneity between studies. Further research is needed to characterise the impact of maternal death and breastfeeding on the survival of HEU infants in the context of maternal ART, where current evidence is limited.

Abstract
OBJECTIVE HIV-exposed but HIV-uninfected (HEU) children are widely considered at increased risk of mortality and morbidity. Recent advances in prevention of mother-to-child HIV transmission (PMTCT) strategies, incorporating life-long universal maternal antiretroviral therapy (ART, "Option B+") with extended breastfeeding, may improve HEU child health substantially. We critically reviewed reports of mortality/morbidity among HEU and HIV-unexposed (HU) children in sub-Saharan Africa. METHODS We searched Medline, EMBASE, CINAHL, PsycINFO, Academic Search Premier, Global Health & Psychosocial Instruments databases, conference abstracts, and reference lists for longitudinal studies from sub-Saharan Africa reporting mortality and clinical morbidity among HIV-uninfected children aged ≤10 years, by maternal HIV status. Studies were appraised by Newcastle-Ottawa Scale and ACROBAT-NRSI. Due to substantial heterogeneity of study designs, populations and results (I(2) = 75%), data were not synthesised. RESULTS We included 37 reports (28 studies, 11 164 HEU children); methodological and reporting quality were variable. Most reports came from settings without universal access to maternal ART (n = 35). Results were conflicting, with some studies indicating increased risk of mortality, hospitalisation and/or under-nutrition among HEU children, while others found no evidence of increased risk. In subanalyses, improved maternal health, ART use and breastfeeding were strongly protective for all outcomes. Only 39% (11/28) of studies adjusted for major confounders. Reports from settings using universal maternal ART with breastfeeding (n = 2) found no differences in growth or development but did not report mortality or infectious morbidity. CONCLUSIONS The existing literature provides little insight into HEU child health under recently adopted PMTCT strategies. There is a need for robust comparative data on HEU and HIV-unexposed child health outcomes under Option B+; optimising breastfeeding practices and increasing maternal use of ART should be urgent public health priorities.

Abstract
BACKGROUND Increased morbidity and mortality from lower respiratory tract infection (LRTI) has been suggested in HIV-exposed uninfected (HEU) children; however, the contribution of respiratory viruses is unclear. We studied the epidemiology of LRTI hospitalization in HIV-unexposed uninfected (HUU) and HEU infants aged <6 months in South Africa. METHODS We prospectively enrolled hospitalized infants with LRTI from 4 provinces from 2010 to 2013. Using polymerase chain reaction, nasopharyngeal aspirates were tested for 10 viruses and blood for pneumococcal DNA. Incidence for 2010-2011 was estimated at 1 site with population denominators. RESULTS We enrolled 3537 children aged <6 months. HIV infection and exposure status were determined for 2507 (71%), of whom 211 (8%) were HIV infected, 850 (34%) were HEU, and 1446 (58%) were HUU. The annual incidence of LRTI was elevated in HEU (incidence rate ratio [IRR] 1.4; 95% confidence interval [CI] 1.3-1.5) and HIV infected (IRR 3.8; 95% CI 3.3-4.5), compared with HUU infants. Relative incidence estimates were greater in HEU than HUU, for respiratory syncytial virus (RSV; IRR 1.4; 95% CI 1.3-1.6) and human metapneumovirus-associated (IRR 1.4; 95% CI 1.1-2.0) LRTI, with a similar trend observed for influenza (IRR 1.2; 95% CI 0.8-1.8). HEU infants overall, and those with RSV-associated LRTI had greater odds (odds ratio 2.1, 95% CI 1.1-3.8, and 12.2, 95% CI 1.7-infinity, respectively) of death than HUU. CONCLUSIONS HEU infants were more likely to be hospitalized and to die in-hospital than HUU, including specifically due to RSV. This group should be considered a high-risk group for LRTI.

Abstract
The number of infants infected with HIV is declining with the rise in interventions for the elimination of paediatric HIV infection, but the number of uninfected infants exposed to HIV through their HIV-infected mothers is increasing. Interest in the health outcomes of HIV-exposed, uninfected infants has grown in the past decade, with several studies suggesting that these infants have increased mortality rates, increased infectious morbidity, and impaired growth compared with HIV-unexposed infants. However, heterogeneous results might reflect the inherent challenges in studies of HIV-exposed, uninfected infants, which need large populations with appropriate, contemporaneous comparison groups and repeated HIV testing throughout the period of breastfeeding. We review the effects of HIV exposure on mortality, morbidity, and growth, discuss the immunological abnormalities identified so far, and provide an overview of interventions that could be effective in this susceptible population. As the number of infants infected with HIV declines, the health needs of HIV-exposed, uninfected infants should be prioritised further, to ensure that post-2015 Sustainable Development Goals are achieved.

Abstract
Background The benefits of male partner involvement in antenatal care (ANC) and prevention of mother-to-child transmission of HIV (PMTCT) for maternal and infant health outcomes have been well recognised. However, in many sub-Saharan African settings, male involvement in these services remains low. Previous research has suggested written invitation letters as a way to promote male partner involvement. Methods In this implementation study conducted at three study sites in southwest Tanzania, acceptability of written invitation letters for male partners was assessed. Pre-study CVCT rates of 2–19 % had been recorded at the study sites. Pregnant women approaching ANC without a male partner were given an official letter, inviting the partner to attend a joint ANC and couple voluntary counselling and testing (CVCT) session. Partner attendance was recorded at subsequent antenatal visits, and the invitation was repeated if the partner did not attend. Analysis of socio-demographic indices associated with male partner attendance at ANC was also performed. Results Out of 318 women who received an invitation letter for their partner, 53.5 % returned with their partners for a joint ANC session; of these, 81 % proceeded to CVCT. Self-reported HIV-positive status at baseline was negatively associated with partner return (p = 0.033). Male attendance varied significantly between the rural and urban study sites (p < 0.001) with rates as high as 76 % at the rural site compared to 31 % at the urban health centre. The majority of women assessed the joint ANC session as a favourable experience, however 7 (75 %) of women in HIV-positive discordant or concordant relationships reported problems during mutual disclosure. Beneficial outcomes reported one month after the session included improved client- provider relationship, improved intra-couple communication and enhanced sexual and reproductive health decision-making. Conclusion Official invitation letters are a feasible intervention in a resource limited sub-Saharan African context, they are highly accepted by couple members, and are an effective way to encourage men to attend ANC and CVCT. Pre-intervention CVCT rates were improved in all sites. However, urban settings might require extra emphasis to reach high rates of partner attendance compared to smaller rural health centres.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe. J Int AIDS Soc 2015; 18:20022.

Abstract
Introduction High retention in care is paramount to reduce vertical human immunodeficiency virus (HIV) infections in prevention of mother-to-child transmission (PMTCT) programmes but remains low in many sub-Saharan African countries. We aimed to assess the effects of community health worker–based defaulter tracing (CHW-DT) on retention in care and mother-to-child HIV transmission, an innovative approach that has not been evaluated to date. Methods We analyzed patient records of 1878 HIV-positive pregnant women and their newborns in a rural PMTCT programme in the Tsholotsho district of Zimbabwe between 2010 and 2013 in a retrospective cohort study. Using binomial regression, we compared vertical HIV transmission rates at six weeks post-partum, and retention rates during the perinatal PMTCT period (at delivery, nevirapine [NVP] initiation at three days post-partum, cotrimoxazole (CTX) initiation at six weeks post-partum, and HIV testing at six weeks post-partum) before and after the introduction of CHW-DT in the project. Results Median maternal age was 27 years (inter-quartile range [IQR] 23 to 32) and median CD4 count was 394 cells/µL3 (IQR 257 to 563). The covariate-adjusted rate ratio (aRR) for perinatal HIV transmission was 0.72 (95% confidence intervals [95% CI] 0.27 to 1.96, p=0.504), comparing patient outcomes after and before the intervention. Among fully retained patients, 11 (1.9%) newborns tested HIV positive. ARRs for retention in care were 1.01 (95% CI 0.96 to 1.06, p=0.730) at delivery; 1.35 (95% CI 1.28 to 1.42, p<0.001) at NVP initiation; 1.78 (95% CI 1.58 to 2.01, p<0.001) at CTX initiation; and 2.54 (95% CI 2.20 to 2.93, p<0.001) at infant HIV testing. Cumulative retention after and before the intervention was 496 (85.7%) and 1083 (87.3%) until delivery; 480 (82.9%) and 1005 (81.0%) until NVP initiation; 303 (52.3%) and 517 (41.7%) until CTX initiation; 272 (47.0%) and 427 (34.4%) until infant HIV testing; and 172 (29.7%) and 405 (32.6%) until HIV test result collection. Conclusions The CHW-DT intervention did not reduce perinatal HIV transmission significantly. Retention improved moderately during the post-natal period, but cumulative retention decreased rapidly even after the intervention. We showed that transmission in resource-limited settings can be as low as in resource-rich countries if patients are fully retained in care. This requires structural changes to the regular PMTCT services, in which community health workers can, at best, play a complementary role.

Abstract
OBJECTIVES To determine antibiotic susceptibility of colonising pneumococcal serotypes in HIV-exposed infants before the introduction of the 13-valent pneumococcal conjugate vaccine (PCV13), because HIV-exposed infants are at increased risk of invasive pneumococcal infections. METHODS Antibiotic susceptibility of 104 pneumococcal isolates, cultured from the nasopharynx from Tanzanian HIV-exposed infants, was determined using the disc diffusion method and the E-test according to EUCAST version 4.0 (2014) criteria. RESULTS A total of 69.2% of isolates were intermediately susceptible for benzyl penicillin (MIC 0.06-2 mg/l ); no high-level resistance was found. All isolates but one were susceptible to ampicillin. Regarding non-beta-lactam antibiotics, 19.2% of isolates were resistant to doxycycline, 3.8% to erythromycin and 97.1% to trimethoprim/sulfamethoxazole. A total of 15.4% of isolates were resistant to three antibiotic classes or more. There were no differences in antibiotic susceptibility between vaccine and non-vaccine serotypes. Reduced susceptibility of colonising pneumococcal isolates for commonly used antibiotics is common in HIV-exposed Tanzanian infants. CONCLUSIONS High-dose penicillin and ampicillin remain appropriate first choices for non-meningeal pneumococcal infections in this group.

Abstract
BACKGROUND Despite the overwhelming evidence confirming the morbidity and mortality benefits of early initiation of highly active anti-retroviral therapy (HAART) in HIV-infected infants, some children are still disadvantaged from gaining access to care. The understanding of the maternal perspective on early infant HIV diagnosis and prompt initiation of HAART has not been adequately explored, especially in the rural communities of South Africa. This study explores the perspectives of mothers of HIV-exposed infants with regard to early infant diagnosis (EID) through a lens of social and structural barriers to accessing primary healthcare in OR Tambo district, Eastern Cape Province, South Africa. METHODS In this qualitative study, we conducted semi-structured interviews at two primary healthcare centres in the King Sabata Dalindyebo Municipality of the OR Tambo district, South Africa. Twenty-four purposive sample of mothers of HIV-exposed infants took part in the study. Interviews were tape-recorded, transcribed and field notes were obtained. The findings were triangulated with two focus group discussions in order to enrich and validate the qualitative data. Thematic content analysis was employed to analyse the data. RESULTS The participants have fairly good knowledge of mother-to-child transmission of HIV and the risks during pregnancy, delivery and breastfeeding. The majority of participants were confident of the protection offered by anti-retroviral drugs provided during pregnancy, however, lack knowledge of optimal time for early infant diagnosis of HIV. Reasons for not accessing EID included fear of finding out that their child is HIV positive, feelings of guilt and/or shame and embarrassment with respect to raising an HIV infected infant. Personal experiences of HIV diagnosis and HAART were associated with participants' attitudes and beliefs toward care-seeking behaviours. Stigma resulting from their own disclosure to others reduced their likelihood of recommending EID to other members of their communities. CONCLUSION Despite the good knowledge of mothers about infant HIV infection and the availability of treatment, the knowledge of the optimal time for early infant diagnosis is lacking. Fear of infant HIV diagnosis and stigma are challenges for universal coverage of early infant diagnosis in these rural communities. Hence, community education and intensive counselling of pregnant women about early infant diagnosis are urgently needed.

Abstract
Background HIV suppression at parturition is beneficial for maternal, fetal and public health. To eliminate mother-to-child transmission of HIV, an understanding of missed opportunities for antiretroviral therapy (ART) use during pregnancy and HIV suppression at delivery is required. Methodology We performed a retrospective analysis of 836 mother-to-child pairs involving 656 HIV-infected women in Philadelphia, 2005-2013. Multivariable regression examined associations between patient (age, race/ethnicity, insurance status, drug use) and clinical factors such as adequacy of prenatal care measured by the Kessner index which classifies prenatal care as inadequate, intermediate, or adequate prenatal care; timing of HIV diagnosis; and the outcomes: receipt of ART during pregnancy and viral suppression at delivery. Results Overall, 25% of the sample was diagnosed with HIV during pregnancy; 39%, 38%, and 23% were adequately, intermediately, and inadequately engaged in prenatal care. Eight-five percent of mother-to-child pairs received ART during pregnancy but only 52% achieved suppression at delivery. Adjusting for patient factors, pairs diagnosed with HIV during pregnancy were less likely to receive ART (AOR 0.39, 95% CI 0.25-0.61) and achieve viral suppression (AOR 0.70, 95% CI 0.49-1.00) than those diagnosed before pregnancy. Similarly, women with inadequate prenatal care were less likely to receive ART (AOR 0.06, 95% CI 0.03-0.11) and achieve viral suppression (AOR 0.31, 95% CI 0.20-0.47) than those with adequate prenatal care. Conclusions Targeted interventions to diagnose HIV prior to pregnancy and engage HIV-infected women in prenatal care have the potential to improve HIV related outcomes in the perinatal period.

Increased risk for and mortality from invasive pneumococcal disease in HIV-exposed but uninfected infants aged <1 year in South Africa, 2009-2013. Clin Infect Dis 2015; 60:1346-56. [PMID: 25645212 DOI: 10.1093/cid/civ059] [Citation(s) in RCA: 80] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2014] [Accepted: 12/28/2014] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND High antenatal human immunodeficiency virus (HIV) seroprevalence rates (∼ 30%) with low perinatal HIV transmission rates (2.5%), due to HIV prevention of mother-to-child transmission program improvements in South Africa, has resulted in increasing numbers of HIV-exposed but uninfected (HEU) children. We aimed to describe the epidemiology of invasive pneumococcal disease (IPD) in HEU infants. METHODS We conducted a cross-sectional study of infants aged <1 year with IPD enrolled in a national, laboratory-based surveillance program for incidence estimations. Incidence was reported for 2 time points, 2009 and 2013. At enhanced sites we collected additional data including HIV status and in-hospital outcome. RESULTS We identified 2099 IPD cases in infants from 2009 to 2013 from all sites. In infants from enhanced sites (n = 1015), 92% had known HIV exposure status and 86% had known outcomes. IPD incidence was highest in HIV-infected infants, ranging from 272 to 654 per 100,000 population between time points (2013 and 2009), followed by HEU (33-88 per 100,000) and HIV-unexposed and uninfected (HUU) infants (18-28 per 100,000). The case-fatality rate in HEU infants (29% [74/253]) was intermediate between HUU (25% [94/377]) and HIV-infected infants (34% [81/242]). When restricted to infants <6 months of age, HEU infants (37% [59/175]) were at significantly higher risk of dying than HUU infants (32% [51/228]; adjusted relative risk ratio, 1.76 [95% confidence interval, 1.09-2.85]). DISCUSSION HEU infants are at increased risk of IPD and mortality from IPD compared with HUU children, especially as young infants. HEU infants, whose numbers will likely continue to increase, should be prioritized for interventions such as pneumococcal vaccination along with HIV-infected infants and children.

Electricity-free amplification and detection for molecular point-of-care diagnosis of HIV-1. PLoS One 2014; 9:e113693.

Abstract
In resource-limited settings, the lack of decentralized molecular diagnostic testing and sparse access to centralized medical facilities can present a critical barrier to timely diagnosis, treatment, and subsequent control and elimination of infectious diseases. Isothermal nucleic acid amplification methods, including reverse transcription loop-mediated isothermal amplification (RT-LAMP), are well-suited for decentralized point-of-care molecular testing in minimal infrastructure laboratories since they significantly reduce the complexity of equipment and power requirements. Despite reduced complexity, however, there is still a need for a constant heat source to enable isothermal nucleic acid amplification. This requirement poses significant challenges for laboratories in developing countries where electricity is often unreliable or unavailable. To address this need, we previously developed a low-cost, electricity-free heater using an exothermic reaction thermally coupled with a phase change material. This heater achieved acceptable performance, but exhibited considerable variability. Furthermore, as an enabling technology, the heater was an incomplete diagnostic solution. Here we describe a more precise, affordable, and robust heater design with thermal standard deviation <0.5°C at operating temperature, a cost of approximately US$.06 per test for heater reaction materials, and an ambient temperature operating range from 16°C to 30°C. We also pair the heater with nucleic acid lateral flow (NALF)-detection for a visual readout. To further illustrate the utility of the electricity-free heater and NALF-detection platform, we demonstrate sensitive and repeatable detection of HIV-1 with a ß-actin positive internal amplification control from processed sample to result in less than 80 minutes. Together, these elements are building blocks for an electricity-free platform capable of isothermal amplification and detection of a variety of pathogens.

Abstract
BACKGROUND The fifth Millennium Development Goal (MDG 5) established the goal of a 75% reduction in the maternal mortality ratio (MMR; number of maternal deaths per 100,000 livebirths) between 1990 and 2015. We aimed to measure levels and track trends in maternal mortality, the key causes contributing to maternal death, and timing of maternal death with respect to delivery. METHODS We used robust statistical methods including the Cause of Death Ensemble model (CODEm) to analyse a database of data for 7065 site-years and estimate the number of maternal deaths from all causes in 188 countries between 1990 and 2013. We estimated the number of pregnancy-related deaths caused by HIV on the basis of a systematic review of the relative risk of dying during pregnancy for HIV-positive women compared with HIV-negative women. We also estimated the fraction of these deaths aggravated by pregnancy on the basis of a systematic review. To estimate the numbers of maternal deaths due to nine different causes, we identified 61 sources from a systematic review and 943 site-years of vital registration data. We also did a systematic review of reports about the timing of maternal death, identifying 142 sources to use in our analysis. We developed estimates for each country for 1990-2013 using Bayesian meta-regression. We estimated 95% uncertainty intervals (UIs) for all values. FINDINGS 292,982 (95% UI 261,017-327,792) maternal deaths occurred in 2013, compared with 376,034 (343,483-407,574) in 1990. The global annual rate of change in the MMR was -0·3% (-1·1 to 0·6) from 1990 to 2003, and -2·7% (-3·9 to -1·5) from 2003 to 2013, with evidence of continued acceleration. MMRs reduced consistently in south, east, and southeast Asia between 1990 and 2013, but maternal deaths increased in much of sub-Saharan Africa during the 1990s. 2070 (1290-2866) maternal deaths were related to HIV in 2013, 0·4% (0·2-0·6) of the global total. MMR was highest in the oldest age groups in both 1990 and 2013. In 2013, most deaths occurred intrapartum or postpartum. Causes varied by region and between 1990 and 2013. We recorded substantial variation in the MMR by country in 2013, from 956·8 (685·1-1262·8) in South Sudan to 2·4 (1·6-3·6) in Iceland. INTERPRETATION Global rates of change suggest that only 16 countries will achieve the MDG 5 target by 2015. Accelerated reductions since the Millennium Declaration in 2000 coincide with increased development assistance for maternal, newborn, and child health. Setting of targets and associated interventions for after 2015 will need careful consideration of regions that are making slow progress, such as west and central Africa.

Impact of HIV exposure on health outcomes in HIV-negative infants born to HIV-positive mothers in Sub-Saharan Africa. J Acquir Immune Defic Syndr 2014; 65:182-9. [PMID: 24442224 DOI: 10.1097/qai.0000000000000019] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Up to 30% of infants may be HIV-exposed noninfected (ENI) in countries with high HIV prevalence, but the impact of maternal HIV on the child's health remains unclear. METHODS One hundred fifty-eight HIV ENI and 160 unexposed (UE) Mozambican infants were evaluated at 1, 3, 9, and 12 months postdelivery. At each visit, a questionnaire was administered, and HIV DNA polymerase chain reaction and hematologic and CD4/CD8 determinations were measured. Linear mixed models were used to evaluate differences in hematologic parameters and T-cell counts between the study groups. All outpatient visits and admissions were registered. ENI infants received cotrimoxazol prophylaxis (CTXP). Negative binomial regression models were estimated to compare incidence rates of outpatient visits and admissions. RESULTS Hematocrit was lower in ENI than in UE infants at 1, 3, and 9 months of age (P = 0.024, 0.025, and 0.012, respectively). Percentage of CD4 T cells was 3% lower (95% confidence interval: 0.86 to 5.15; P = 0.006) and percentage of CD8 T cells 1.15 times higher (95% confidence interval: 1.06 to 1.25; P = 0.001) in ENI vs. UE infants. ENI infants had a lower weight-for-age Z score (P = 0.049) but reduced incidence of outpatient visits, overall (P = 0.042), diarrhea (P = 0.001), and respiratory conditions (P = 0.042). CONCLUSIONS ENI children were more frequently anemic, had poorer nutritional status, and alterations in some immunologic profiles compared with UE children. CTXP may explain their reduced mild morbidity. These findings may reinforce continuation of CTXP and the need to understand the consequences of maternal HIV exposure in this vulnerable group of children.

Abstract
Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV's perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV.

Abstract
BACKGROUND Starting lifelong antiretroviral therapy (ART) in HIV-infected pregnant women may decrease HIV progression and transmission, but adherence after delivery may be difficult, especially for asymptomatic women. We evaluated disease progression among HIV-infected women not on ART with CD4⁺ lymphocyte counts above 200 cells per microliter at delivery. METHODS We analyzed risk of death, progression to AIDS (stage IV or CD4 < 200 cells per microliter), or to CD4⁺ count <350 1 year after delivery among postpartum women enrolled to a prevention of breastfeeding transmission trial using the Kaplan-Meier method. In the primary analysis, women were censored if ART was initiated. RESULTS Among 1285 women who were not WHO stage IV or less at 6 weeks postpartum, 49 (4.3%) progressed to stage IV/CD4 <200 cells per microliter or death by 1 year. Progression to CD4 <200 cells per microliter or death occurred among 16 (4.3%) of 441 women with CD4 count of 350-549 cells per microliter and 10 (1.6%) of 713 with CD4 counts >550 cells per microliter at delivery. CD4 <350 cells per microliter by 12 months postpartum occurred among 116 (37.0%) of 350 women with CD4 count 400-549 cells per microliter and 48 (7.4%) of 713 with CD4 count >550 cells per microliter at delivery. CONCLUSIONS Progression to AIDS or CD4 count <350 cells per microliter is uncommon through 1 year postpartum for women with CD4 counts over 550 cells per microliter at delivery, but occurred in over one third of those with CD4 counts under 550 cells per microliter. ART should be continued after delivery or breastfeeding among women with CD4 counts <550 cells per microliter if follow-up and antiretroviral adherence can be maintained.

Calvert C, Ronsmans C. HIV and the risk of direct obstetric complications: a systematic review and meta-analysis. PLoS One 2013; 8:e74848. [PMID: 24124458 PMCID: PMC3790789 DOI: 10.1371/journal.pone.0074848] [Citation(s) in RCA: 54] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2013] [Accepted: 08/05/2013] [Indexed: 11/18/2022] Open
Abstract
Background Women of reproductive age in parts of sub-Saharan Africa are faced both with high levels of HIV and the threat of dying from the direct complications of pregnancy. Clinicians practicing in such settings have reported a high incidence of direct obstetric complications among HIV-infected women, but the evidence supporting this is unclear. The aim of this systematic review is to establish whether HIV-infected women are at increased risk of direct obstetric complications. Methods and findings Studies comparing the frequency of obstetric haemorrhage, hypertensive disorders of pregnancy, dystocia and intrauterine infections in HIV-infected and uninfected women were identified. Summary estimates of the odds ratio (OR) for the association between HIV and each obstetric complication were calculated through meta-analyses. In total, 44 studies were included providing 66 data sets; 17 on haemorrhage, 19 on hypertensive disorders, five on dystocia and 25 on intrauterine infections. Meta-analysis of the OR from studies including vaginal deliveries indicated that HIV-infected women had over three times the risk of a puerperal sepsis compared with HIV-uninfected women [pooled OR: 3.43, 95% confidence interval (CI): 2.00–5.85]; this figure increased to nearly six amongst studies only including women who delivered by caesarean (pooled OR: 5.81, 95% CI: 2.42–13.97). For other obstetric complications the evidence was weak and inconsistent. Conclusions The higher risk of intrauterine infections in HIV-infected pregnant and postpartum women may require targeted strategies involving the prophylactic use of antibiotics during labour. However, as the huge excess of pregnancy-related mortality in HIV-infected women is unlikely to be due to a higher risk of direct obstetric complications, reducing this mortality will require non obstetric interventions involving access to ART in both pregnant and non-pregnant women.

Abstract
Background Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal disease. Methodology/Principal Findings A total of 311 HIV-infected pregnant women were enrolled in Malawi in an observational study and received a nevirapine-based regimen from week 25 of gestation until 6 months after delivery (end of breastfeeding period) if their CD4+ count was > 350/mm3 at baseline (n = 147), or indefinitely if they met the criteria for treatment (n. 164). Mother/child pairs were followed until 2 years after delivery. The Kaplan-Meier method was used to estimate HIV transmission, maternal disease progression, and survival at 24 months. The rate of HIV infant infection was 3.2% [95% confidence intervals (CI) 1.0-5.4]. Six of the 8 transmissions occurred among mothers with baseline CD4+ count > 350/mm3. HIV-free survival of children was 85.8% (95% CI 81.4-90.1). Children born to mothers with baseline CD4+ count < 350/mm3 were at increased risk of death (hazard ratio 2.6, 95% CI 1.1-6.1). Among women who had stopped treatment the risk of progression to CD4+ count < 350/mm3 was 20.6% (95% CI 9.2-31.9) by 18 months of drug discontinuation. Conclusions HIV transmission in this cohort was rare however, it occurred in a significative proportion among women with high CD4+ counts. Strategies to improve treatment adherence should be implemented to further reduce HIV transmission. Mortality in the uninfected exposed children was the major determinant of HIV-free survival and was associated to maternal disease stage. Given the considerable proportion of women reaching the criteria for treatment within 18 months of drug discontinuation, life-long ART administration to HIV-infected women should be considered.

Abstract
OBJECTIVES Although much is known about the contribution of HIV to adult mortality, remarkably little is known about the mortality attributable to HIV during pregnancy. In this article we estimate the proportion of pregnancy-related deaths attributable to HIV based on empirical data from a systematic review of the strength of association between HIV and pregnancy-related mortality. METHODS Studies comparing mortality during pregnancy and the postpartum in HIV-infected and HIV-uninfected women were included. Summary estimates of the relative and attributable risks for the association between HIV and pregnancy-related mortality were calculated through meta-analyses. Varying estimates of HIV prevalence were used to predict the impact of the HIV epidemic on pregnancy-related mortality at the population level. RESULTS Twenty-three studies were included (17 from sub-Saharan Africa). Meta-analysis of the risk ratios indicated that HIV-infected women had eight times the risk of a pregnancy-related death compared with HIV-uninfected women [pooled risk ratio 7.74, 95% confidence interval (95% CI) 5.37-11.16]. The excess mortality attributable to HIV among HIV-infected pregnant and postpartum women was 994 per 100,000 pregnant women. We predict that 12% of all deaths during pregnancy and up to 1-year postpartum are attributable to HIV/AIDS in regions with a prevalence of HIV among pregnant women of 2%. This figure rises to 50% in regions with a prevalence of 15%. CONCLUSION The substantial excess of pregnancy-related mortality associated with HIV highlights the importance of integrating HIV and reproductive health services in areas of high HIV prevalence and pregnancy-related mortality.

Abstract
OBJECTIVES To evaluate the effectiveness of a prevention programme against the vertical transmission of HIV in a resource-limited setting and to investigate variables associated with compliance. PATIENTS AND METHODS The Kento-Mwana project (2005-2008) provided counselling, serological and biomolecular testing and prophylaxis/therapy to HIV-positive pregnant women and their children attending four antenatal clinics in Pointe Noire, Republic of Congo. Expected and actual rates of vertical transmission of HIV were compared. Univariate and multivariate analyses were performed in order to identify variables associated with non-compliance. RESULTS The observed transmission rate in the group who completed follow-up was 5/290 (1.7%, 95% CI 0.6%-4.1%). The overall estimated transmission rate in the target population, computed taking into account the expected vertical transmission of HIV among drop-outs, was 67-115/638 (10.5%-18.0%). A comparison between this rate and the expected transmission rate in the absence of intervention (25%-40%) showed that the programme was able to prevent approximately 50% of vertical transmissions. Older age (OR 0.33, 95% CI 0.16-0.66, P = 0.002), telephone availability (OR 0.42, 95% CI 0.24-0.72, P = 0.002) and occupation (OR 0.57, 95% CI 0.29-1.10, P = 0.092) were associated with better compliance. CONCLUSIONS Despite the vast majority of women accepting counselling and testing, many of them refused prophylaxis or dropped out, thus reducing the effectiveness of the intervention from an ideal 2% to a still important but less impressive median transmission rate of 15% (range 10.5%-18%). Promoting participation and compliance, rather than increasing the potency of antiretroviral regimens, is crucial for preventing the vertical transmission of HIV in Africa.

Abstract
Introduction Early infant diagnosis (EID) of HIV infection is an important service to reduce paediatric morbidity and mortality related to HIV/AIDS. Although South Africa has a national EID programme based on PCR testing, there are no population-wide data on the linkage of infants testing HIV PCR-positive to HIV care and treatment services. Methods We conducted a retrospective analysis of all public sector laboratory data from across the Western Cape province between 2005 and 2011. We linked positive HIV PCR results to subsequent HIV viral load testing to determine the proportion of infants who were successfully linked to HIV care. Results A total of 83 698 unique infant HIV PCR tests were documented, of which 6322 (8%) were PCR positive. The proportion of PCR-positive children declined from 12% in 2005 to 3% in 2011. Of the children testing PCR-positive, 4105 (65%) had subsequent viral load testing indicating successful linkage to care. The proportion of successfully linked infants increased from 54% in 2005 to 71% in 2010, while the median delay in days to successful linkage decreased from 146 days in 2005 to 33 days in 2010. Discussion From 2005 to 2011 there has been a reduction in the proportion of children testing HIV PCR-positive, and an increase in the proportion of infected infants successfully linked to HIV care and treatment, in this setting. However a large proportion of infected infants remain unlinked to antiretroviral therapy services and there is a clear need for interventions to further strengthen EID programmes.

Abstract
There has been considerable debate about the effects of targeted global health assistance in low- and middle-income countries on health systems, specifically HIV/AIDS funding. Recently, a handful of studies have emerged that describe the implementation of PMTCT programs, which have many theoretical links to maternal and child health. Through a systematic review of research published between January 2000 and March 2011, this paper synthesizes evidence evaluating the impact of these programs. We assessed 5,855 papers, reviewed 154, and included 21 articles. They offer evidence of beneficial synergies between PMTCT programs and both STI prevention and early childhood immunization. Other data, including information about antenatal and delivery care, family planning, and nutrition supplementation varied considerably across studies demonstrating both positive and negative effects of PMTCT. More research is needed to allow countries and funders to make informed decisions regarding allocation of limited funds to targeted versus broad categories of health care.

Abstract
Reducing childhood mortality in resource-poor regions depends on effective interventions to decrease neonatal mortality from severe infection, which contributes up to a half of all neonatal deaths. There are key differences in resource-poor, compared to resource-rich, countries in terms of diagnosis, supportive care and treatment. In resource-poor settings, diagnosis is based on identifying clinical syndromes from international guidelines; microbiological investigations are restricted to a few research facilities. Low levels of staffing and equipment limit the provision of basic supportive care, and most facilities cannot provide respiratory support. Empiric antibiotic treatment guidelines are based on few aetiological and antimicrobial susceptibility data. Research on improving health care systems to provide effective supportive care, and implementation of simple pragmatic interventions, such as low-cost respiratory support, are essential, together with improved surveillance to monitor emerging drug resistance and treatment failures. Reductions in mortality will also be achieved through prevention of infection; including emerging vaccination and anti-sepsis strategies.

Abstract
Eliminating of paediatric HIV within prevention of mother to child transmission (PMTCT) interventions rests on complete follow-up of all children. We report on predictors of child attrition in the PMTCT cascade over 5 years where 1050 pregnant women were enrolled at 36 gestational weeks. Mother and child pairs were followed up at birth, 6 weeks, 4 months, 9 months, and every 6 months thereafter for 60 months. Higher attrition was observed for children of economically advantaged, socially stable mothers regardless of HIV status, whereas compliance was observed for children whose mothers tested positive for HIV-1, HSV-2 and Syphilis. Low birthweight was associated with attrition regardless of maternal HIV status. Five years predictors of attrition did not differ by maternal HIV status, as HIV-exposed children succumbed to mortality and those not exposed were loss to follow-up (LFU). Child follow-up is influenced more by maternal lifestyle and health risks leading to retention of high-risk children in PMTCT programmes.

Abstract
INTRODUCTION Continuous evaluation of child survival is needed in sub-Saharan Africa where HIV prevalence among women of reproductive age continues to be high. We examined mortality levels and trends over a period of ∼20 years among HIV-unexposed and -exposed children in Blantyre, Malawi. METHODS Data from 5 prospective cohort studies conducted at a single research site from 1989 to 2009 were analyzed. In these studies, children born to HIV-infected and -uninfected mothers were enrolled at birth and followed longitudinally for at least 2 years. Information on sociodemographic, HIV infection status, survival, and associated risk factors was collected in all studies. Mortality rates were estimated using birth-cohort analyses stratified by maternal and infant HIV status. Multivariate Cox regression models were used to determine risk factors associated with mortality. RESULTS The analysis included 8286 children. From 1989 to 1995, overall mortality rates (per 100 person-years) in these clinic-based cohorts remained comparable among HIV-uninfected children born to HIV-uninfected mothers (range 3.3-6.9) or to HIV-infected mothers (range 2.5-7.5). From 1989 to 2009, overall mortality remained high among all children born to HIV-infected mothers (range 6.3-19.3) and among children who themselves became infected (range 15.6-57.4, 1994-2009). Only lower birth weight was consistently and significantly (P < 0.05) associated with higher child mortality. CONCLUSIONS HIV infection among mothers and children contributed to high levels of child mortality in the African setting in the pretreatment era. In addition to services that prevent mother-to-child transmission of HIV, other programs are needed to improve child survival by lowering HIV-unrelated mortality through innovative interventions that strengthen health infrastructure.

Abstract
BACKGROUND HIV-exposed newborns may be at higher risk of sepsis because of immune system aberrations, impaired maternal antibody transfer and altered exposure to pathogenic bacteria. METHODS We performed a secondary analysis of a study (clinicaltrials.gov, number NCT00136370) conducted between April 2004 and October 2007 in South Africa. We used propensity score matching to evaluate the association between maternal HIV infection and (1) vaginal colonization with bacterial pathogens; (2) vertical transmission of pathogens to the newborn; and (3) sepsis within 3 days of birth (EOS) or between 4-28 days of life (LOS). RESULTS Colonization with group B Streptococcus (17% vs 23%, P = .0002), Escherichia coli (47% vs 45%, P = .374), and Klebsiella pneumoniae (7% vs 10%, P = .008) differed modestly between HIV-infected and uninfected women, as did vertical transmission rates. Maternal HIV infection was not associated with increased risk of neonatal EOS or LOS, although culture-confirmed EOS was >3 times higher among HIV-exposed infants (P = .05). When compared with HIV-unexposed, neonates, HIV-exposed, uninfected neonates (HEU) had a lower risk of EOS (20.6 vs 33.7 per 1000 births; P = .046) and similar rate of LOS (5.8 vs 4.1; P = .563). HIV-infected newborns had a higher risk than HEU of EOS (134 vs 21.5; P < .0001) and LOS (26.8 vs 5.6; P = .042). CONCLUSIONS Maternal HIV infection was not associated with increased risk of maternal bacterial colonization, vertical transmission, EOS, or LOS. HIV-infected neonates, however, were at increased risk of EOS and LOS.

Abstract
BACKGROUND AND OBJECTIVE The impact of maternal antiretrovirals (ARVs) during pregnancy, labor, and postpartum on infant outcomes is unclear. METHODS Infants born to HIV-infected mothers in ARV studies were followed for 18 months. RESULTS Between June 2006 and December 2008, 236 infants enrolled from Africa (n = 36), India (n = 47), Thailand (n = 152), and Brazil (n = 1). Exposure to ARVs in pregnancy included ≥ 3 ARVs (10%), zidovudine/intrapartum ARV (81%), and intrapartum ARV (9%). There were 4 infant infections (1 in utero, 3 late postpartum) and 4 deaths with 1.8% mortality (95% confidence interval [CI], 0.1%-3.5%) and 96.4% HIV-1-free survival (95% CI, 94.0%-98.9%). Birth weight was ≥ 2.5 kg in 86%. In the first 6 months, Indian infants (nonbreastfed) had lowest median weights and lengths and smallest increases in growth. After 6 months, African infants had the lowest median weight and weight-for-age z scores. Infants exposed to highest maternal viral load had the lowest height and height-for-age z scores. Serious adverse events occurred in 38% of infants, did not differ by country, and correlated with less maternal ARV exposure. Clinical diagnoses were seen in 84% of Thai, 31% of African, and 9% of Indian infants. Congenital defects/inborn errors of metabolism were seen in 18 (7.6%) infants, of which 17 were Thai (11%: 95% CI, 6.7%-17.0%); none had first trimester ARV exposure. CONCLUSIONS Infant follow-up in large international cohorts is feasible and provides important safety and HIV transmission data following maternal ARV exposure. Increased surveillance increases identification of congenital/inborn errors.

Abstract
Background Early diagnosis of HIV in infants provides a critical opportunity to strengthen follow-up of HIV-exposed children and assure early access to antiretroviral (ARV) treatment for infected children. This study describes findings from an Early Infant Diagnosis (EID) program and the effectiveness of a prevention of mother-to-child transmission (PMTCT) intervention in six health facilities in Cross-River and Akwa-Ibom states, south-south Nigeria. Methods This was a retrospective study. Records of 702 perinatally exposed babies aged six weeks to 18 months who had a DNA PCR test between November 2007 and July 2009 were reviewed. Details of the ARV regimen received to prevent mother-to-child transmission (MTCT), breastfeeding choices, HIV test results, turn around time (TAT) for results and post test ART enrolment status of the babies were analysed. Results Two-thirds of mother-baby pairs received ARVs and 560 (80%) babies had ever been breastfed. Transmission rates for mother-baby pairs who received ARVs for PMTCT was 4.8% (CI 1.3, 8.3) at zero to six weeks of age compared to 19.5% (CI 3.0, 35.5) when neither baby nor mother received an intervention. Regardless of intervention, the transmission rates for babies aged six weeks to six months who had mixed feeding was 25.6% (CI 29.5, 47.1) whereas the transmission rates for those who were exclusively breastfed was 11.8% (CI 5.4, 18.1). Vertical transmission of HIV was eight times (AOR 7.8, CI: 4.52-13.19) more likely in the sub-group of mother-baby pairs who did not receive ARVS compared with mother-baby pairs that did receive ARVs. The median TAT for test results was 47 days (IQR: 35-58). A follow-up of 125 HIV positive babies found that 31 (25%) were enrolled into a paediatric ART program, nine (7%) were known to have died before the return of their DNA PCR results, and 85 (67%) could not be traced and were presumed to be lost-to-follow-up. Conclusion Reduction of MTCT of HIV is possible with effective PMTCT interventions, including improved access to ARVs for PMTCT and appropriate infant feeding practices. Loss to follow up of HIV exposed infants is a challenge and requires strategies to enhance retention.
