Abstract
INTRODUCTION The large number of deaths among children with HIV is driven by poor antiretroviral treatment (ART) coverage among this cohort. The aim of the study was to assess the availability and stock-outs of paediatric and adult ART formulations in Kenya and Uganda across various regions and types of health facilities. METHODS A survey on availability and stock-outs of paediatric ART at health facilities was adapted from the standardized Health Action International-WHO Medicine Availability Monitoring Tool. All preferred and limited-use formulations, and three phased-out formulations according to the 2021 WHO optimal formulary list were included in the survey, as well as a selection of adult ART formulations suitable for older children, adolescents, and adults. Availability data were collected in June-July 2022 and stock-out data were obtained over the previous year from randomly selected public and private-not-for-profit (PNFP) facilities registered to dispense paediatric ART across six districts per country. All data were analysed descriptively. RESULTS In total, 144 health facilities were included (72 per country); 110 were public and 34 PNFP facilities. Overall availabilities of preferred paediatric ART formulations were 52.2% and 63.5% in Kenya and Uganda, respectively, with dolutegravir (DTG) 10 mg dispersible tablets being available in 70.2% and 77.4% of facilities, respectively, and abacavir/lamivudine dispersible tablets in 89.8% and 98.2% of facilities. Of note, availability of both formulations was low (37.5% and 62.5%, respectively) in Kenyan PNFP facilities. Overall availabilities of paediatric limited-use products were 1.1% in Kenya and 1.9% in Uganda. At least one stock-out of a preferred paediatric ART formulation was reported in 40.0% of Kenyan and 74.7% of Ugandan facilities. Nevirapine solution stock-outs were reported in 43.1% of Ugandan facilities, while alternative formulations for postnatal HIV prophylaxis were not available. CONCLUSIONS Recommended DTG-based first-line ART for children across all ages was reasonably available at health facilities in Kenya and Uganda, with the exception of Kenyan PNFP facilities. Availability of paediatric ART formulations on the limited-use list was extremely low across both countries. Stock-outs were reported regularly, with the high number of reported stock-outs of neonatal ART formulations in Uganda being most concerning.

Abstract
BACKGROUND The early childhood development of millions of children in some low- and medium-income countries may be compromised by schistosomiasis infections contracted at the age of 5 years and below. Currently, there are no standard guidelines for treating schistosomiasis in children that are 5 years and younger using praziquantel (PZQ), the only drug that the World Health Organization (WHO) recommends for treating schistosomiasis. The review is on processes and resources involved in the treatment of schistosomiasis in children aged 5 years and below. METHODS An electronic search for peer-reviewed articles published in the period from January 2011 to August 2021 was done in the Academic Search Complete, CINAHL with Full Text, Health Source: Nursing/Academic Edition, and MEDLINE databases via EBSCOHost and Google Scholar databases. The search targeted journals that described the treatment of schistosomiasis in children 5 years and below using praziquantel. RESULTS Thirteen studies met the inclusion criteria. The patient journey for treating schistosomiasis in children aged 5 years old and below using PZQ included the following activities: enrolment of the children into the treatment program; clinical examination; diagnosis; taking anthropometric measurements; feeding the children, making the PZQ palatable to the children; administration of PZQ; and monitoring of side effects. There was also a variation in the resources used to treat children aged 5 and below for schistosomiasis. CONCLUSIONS A PZQ mass drug administration program for children aged 5 years old and below in endemic areas should exclude the diagnosis of schistosomiasis before treatment. The resources required in the treatment process should be affordable, and should not require skills and maintenance resources that are beyond those that are available at the primary healthcare level.

[PMID: 32985699 DOI: 10.1002/jmv.26562] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 09/08/2020] [Accepted: 09/25/2020] [Indexed: 11/09/2022]
Abstract
GOAL The goal of this study is to determine the prevalence of therapeutic failure and the evolution of the biological factors after 6 and 12 months of anti-retroviral treatment (ART) amongst human immunodefeciency virus (HIV) Patients receiving care through the Ambulatory Treatment Center in Nouakchott. METHODS The study presents a descriptive and retrospective analysis of 479 patients enrolled in ART between January 2015 and January 2019, with focus on treatment failures and related biomarkers. The average age of the patients studied was 37 ± 12.94 years. The majority (52.8%) were males, of whom (52.6%) were married. RESULTS The average body mass index (BMI) of the patients progressively increased after 6 and 12 months on ART. The average BMI increased from 20.3 ± 5.1 kg/m2 , before treatment, to 21.7 ± 5.0 kg/m2 and 22.7 ± 5.4 kg/m2 , after 6 and 12 months of treatment, respectively. Of the 479 patients, 97.3% were on 2 NRTIs + NNRTI. During the first 6 months of treatment, the clinical, immunological, and virological therapeutic failures were 0.6%, 34.10%, and 9%, respectively. After 6 and 12 months of ART, the TCD4, Hemoglobin, platelets, glycemia, creatinemia, and transaminase remained normal during the entire monitoring period. CONCLUSION study demonstrated effective HIV treatment amongst the study patients. It showed clearance of virus and immune restoration can be attained after 6 and 12 months of ART. The number of patients who received the tests did decrease during the treatment period, which highlights the importance of adherence to patient management protocols, including clinical and biological monitoring.

Receipt of infant HIV DNA PCR test results is associated with a reduction in retention of HIV-exposed infants in integrated HIV care and healthcare services: a quantitative sub-study nested within a cluster randomised trial in rural Malawi. BMC Public Health 2020; 20:1879. [PMID: 33287772 PMCID: PMC7720620 DOI: 10.1186/s12889-020-09973-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 11/25/2020] [Indexed: 11/29/2022] Open
Abstract
Background Retention of HIV-infected mothers in integrated HIV and healthcare facilities is effective at reducing mother-to-child-transmission (MTCT) of HIV. In the context of Option B+, we examined maternal and HIV-exposed infant retention across three study arms to 18 months postpartum: mother-and-infant clinics (MIP), MIP with short-messaging service (MIP + SMS) and standard of care (SOC). In particular, we focused on the impact of mothers receiving an infant’s HIV PCR test result on maternal and infant study retention. Methods A quantitative sub-study nested within a cluster randomised trial undertaken between May 2013 and August 2016 across 30 healthcare facilities in rural Malawi enrolling HIV-infected pregnant mothers and HIV-exposed infants on delivery, was performed. Survival probabilities of maternal and HIV-exposed infant study retention was estimated using Kaplan-Meier curves. Associations between mother’s receiving an infant’s HIV test result and in particular, an infant’s HIV-positive result on maternal and infant study retention were modelled using time-varying multivariate Cox regression. Results Four hundred sixty-one, 493, and 396 HIV-infected women and 386, 399, and 300 HIV-exposed infants were enrolled across study arms; MIP, MIP + SMS and SOC, respectively. A total of 47.5% of mothers received their infant’s HIV test results < 5 months postpartum. Receiving an infant’s HIV result by mothers was associated with a 70% increase in infant non-retention in the study compared with not receiving an infant’s result (HR = 1.70; P-value< 0.001). Receiving a HIV-positive result was associated with 3.12 times reduced infant retention compared with a HIV-negative result (P-value< 0.001). Of the infants with a HIV-negative test result, 87% were breastfed at their final study follow-up. Conclusions Receiving an infant’s HIV test result was a driving factor for reduced infant study retention, especially an infant’s HIV-positive test result. As most HIV-negative infants were still breastfed at their last follow-up, this indicates a large proportion of HIV-exposed infants were potentially at future risk of MTCT of HIV via breastfeeding but were unlikely to undergo follow-up HIV testing after breastfeeding cessation. Future studies to identify and address underlying factors associated with infant HIV testing and reduced infant retention could potentially improve infant retention in HIV/healthcare facilities.

Abstract
BACKGROUND Improving health literacy amongst human immunodeficiency virus (HIV)-positive mothers could strengthen child and adolescent HIV prevention. The Amagugu intervention included health literacy materials to strengthen maternal communication and has demonstrated success in low-resource HIV-endemic settings. OBJECTIVES Our aims were to (1) evaluate whether Amagugu materials improved health literacy leading to changes in parental behaviour towards communicating on topics such as HIV, health behaviours and sex education, and (2) explore what additional information and materials mothers would find helpful. METHOD The Amagugu evaluation included 281 HIV-positive mothers and their HIV-uninfected children (6-10 years). Process evaluation data from exit interviews were analysed using content analysis and logistic regression techniques. RESULTS Of 281 mothers, 276 (98.0%) requested more educational storybooks: 99 (35.2%) on moral development/future aspirations, 92 (32.7%) on general health, safety and health promotion, and 67 (23.8%) on HIV and disease management. Compared to baseline, mothers reported that the materials increased discussion on the risks of bullying from friends (150; 53.4%), teacher problems (142; 50.5%), physical abuse (147; 52.3%) and sexual abuse (126; 44.8%). Most mothers used the 'HIV Body Map' for health (274; 97.5%) and sex education (267; 95.0%). The use of a low-cost doll was reported to enhance mother-child communication by increasing mother-child play (264; 94.3%) and maternal attentiveness to the child's feelings (262; 93.6%). CONCLUSION Parent-led health education in the home seems feasible, acceptable and effective and should be capitalised on in HIV prevention strategies. Further testing in controlled studies is recommended.

Abstract
INTRODUCTION The best method to measure adherence to antiretroviral therapy (ART) in resource-limited settings has not yet been established, particularly among adolescents and young adults (AYAs). The use of mobile technology may address the need for standardized tools in measuring adherence in this often marginalized population. METHODS We conducted a cross-sectional validation study among AYAs (18-35 years) attending a South African HIV clinic between 07/2015-09/2017. We determine the diagnostic accuracy of two modes of delivering an adherence questionnaire (self-administered electronic vs interviewer-administered paper-adherence questionnaire) comprising two self-reported adherence tools (South African National Department of Health (NDoH) adherence questionnaire and the Simplified Medication Adherence Questionnaire (SMAQ)) to identify poor adherence compared to; 1) a detectable viral load (≥1000 copies/mL) and 2) a sub-optimal concentration of efavirenz (EFV) (EFV ≤1.00 µg/mL) measured by therapeutic drug monitoring (TDM). RESULTS Of 278 included participants, 7.1% and 7.3% completing the electronic- and paper-questionnaires had a detectable viral load, while 14.7% and 16.5% had a sub-optimal concentration of EFV, respectively. According to viral load monitoring, the electronic-adherence questionnaire had a higher sensitivity (Se) in detecting poor adherence than the paper-based version across the NDoH adherence questionnaire (Se: 63.6% vs 33.3%) and SMAQ (Se: 90.9% vs 66.7%). In contrast, when using blood drug concentration (EFV ≤1.00 µg/mL), the paper-adherence questionnaire produced a higher sensitivity across both adherence tools; namely the NDoH adherence questionnaire (Se: 50.0% vs 38.1%) and SMAQ (Se: 75.0% vs 57.1%). CONCLUSION When using more accurate real-time measures of poor adherence such as TDM in this young adult population, we observe a higher sensitivity of an interviewer-administered paper-adherence questionnaire than an identical set of self-administered adherence questions on an electronic tablet. An interviewer-administered questionnaire may elicit more accurate responses from participants through a sense of increased accountability when engaging with health care workers.

Abstract
INTRODUCTION There are limited data on viral suppression (VS) in children with HIV receiving antiretroviral therapy (ART) in routine care in low-resource settings. We examined VS in a cohort of children initiating ART in routine HIV care in Eastern Cape Province, South Africa. METHODS The Pediatric Enhanced Surveillance Study enrolled HIV-infected ART eligibility children zero to twelve years at five health facilities from 2012 to 2014. All children received routine HIV care and treatment services and attended quarterly study visits for up to 24 months. Time to VS among those starting treatment was measured from ART start date to first viral load (VL) result <1000 and VL <50 copies/mL using competing risk estimators (death as competing risk). Multivariable sub-distributional hazards models examined characteristics associated with VS and VL rebound following suppression among those with a VL >30 days after the VS date. RESULTS Of 397 children enrolled, 349 (87.9%) started ART: 118 (33.8%) children age <12 months, 122 (35.0%) one to five years and 109 (31.2%) six to twelve years. At study enrolment, median weight-for-age z-score (WAZ) was -1.7 (interquartile range (IQR):-3.1 to -0.4) and median log VL was 5.6 (IQR: 5.0 to 6.2). Cumulative incidence of VS <1000 copies/mL at six, twelve and twenty-four months was 57.6% (95% CI 52.1 to 62.7), 78.7% (95% CI 73.7 to 82.9) and 84.0% (95% CI 78.9 to 87.9); for VS <50 copies/mL: 40.3% (95% CI 35.0 to 45.5), 63.9% (95% CI 58.2 to 69.0) and 72.9% (95% CI 66.9 to 78.0). At 12 months only 46.6% (95% CI 36.6 to 56.0) of children <12 months had achieved VS <50 copies/mL compared to 76.9% (95% CI 67.9 to 83.7) of children six to twelve years (p < 0.001). In multivariable models, children with VL >1 million copies/mL at ART initiation were half as likely to achieve VS <50 copies/mL (adjusted sub-distributional hazards 0.50; 95% CI 0.36 to 0.71). Among children achieving VS <50 copies/mL, 37 (19.7%) had VL 50 to 1000 copies/mL and 31 (16.5%) had a VL >1000 copies/mL. Children <12 months had twofold increased risk of VL rebound to VL >1000 copies/mL (adjusted relative risk 2.03, 95% CI: 1.10 to 3.74) compared with six to twelve year olds. CONCLUSIONS We found suboptimal VS among South African children initiating treatment and high proportions experiencing VL rebound, particularly among younger children. Greater efforts are needed to ensure that all children achieve optimal outcomes.

Abstract
Prevention of mother-to-child Transmission and HIV Treatment programmes were scaled-up in resource-constrained settings over a decade ago, but there is still much to be understood about women's experiences of living with HIV and their HIV disclosure patterns. This qualitative study explored women's experiences of living with HIV, 6–10 years after being diagnosed during pregnancy. The area has high HIV prevalence, and an established HIV treatment programme. Participants were enrolled in a larger intervention, “Amagugu”, that supported women (n = 281) to disclose their HIV status to their children. Post-intervention we conducted individual in-depth interviews with 20 randomly selected women, stratified by clinic catchment area, from the total sample. Interviews were entered into ATLAS.ti computer software for coding. Most women were living with their current sexual partner and half were still in a relationship with the child's biological father. Household exposure to HIV was high with the majority of women knowing at least one other HIV-infected adult in their household. Eighteen women had disclosed their HIV status to another person; nine had disclosed to their current partner first. Two main themes were identified in the analyses: living with HIV and the normalisation of HIV treatment at a family level; and the complexity of love relationships, in particular in long-term partnerships. A decade on, most women were living positively with HIV, accessing care, and reported experiencing little stigma. However, as HIV became normalised new challenges arose including concerns about access to quality care, and the need for family-centred care. Women's sexual choices and relationships were intertwined with feelings of love, loyalty and trust and the important supportive role played by partners and families was acknowledged, however, some aspects of living with HIV presented challenges including continuing to practise safe sex several years after HIV diagnosis.

Abstract
Introduction: Lopinavir/ritonavir-based antiretroviral therapy (ART) is recommended for all HIV-infected children less than three years. However, little is known about its field implementation and effectiveness in West Africa. We assessed the 12-month response to lopinavir/ritonavir-based antiretroviral therapy in a cohort of West African children treated before the age of two years. Methods: HIV-1-infected, ART-naive except for a prevention of mother-to-child transmission (PMTCT), tuberculosis-free, and less than two years of age children with parent’s consent were enrolled in a 12-month prospective therapeutic cohort with lopinavir/ritonavir ART and cotrimoxazole prophylaxis in Ouagadougou and Abidjan. Virological suppression (VS) at 12 months (viral load [VL] <500 copies/mL) and its correlates were assessed. Results: Between May 2011 and January 2013, 156 children initiated ART at a median age of 13.9 months (interquartile range: 7.8–18.4); 63% were from Abidjan; 53% were girls; 37% were not exposed to any PMTCT intervention or maternal ART; mother was the main caregiver in 81%; 61% were classified World Health Organization Stage 3 to 4. After 12 months on ART, 11 children had died (7%), 5 were lost-to-follow-up/withdrew (3%), and VS was achieved in 109: 70% of children enrolled and 78% of those followed-up. When adjusting for country and gender, the access to tap water at home versus none (adjusted odds ratio (aOR): 2.75, 95% confidence interval (CI): 1.09–6.94), the mother as the main caregiver versus the father (aOR: 2.82, 95% CI: 1.03–7.71), and the increase of CD4 percentage greater than 10% between inclusion and 6 months versus <10% (aOR: 2.55, 95% CI: 1.05–6.18) were significantly associated with a higher rate of VS. At 12 months, 28 out of 29 children with VL ≥1000 copies/mL had a resistance genotype test: 21 (75%) had ≥1 antiretroviral (ARV) resistance (61% to lamivudine, 29% to efavirenz, and 4% to zidovudine and lopinavir/ritonavir), of which 11 (52%) existed before ART initiation. Conclusions: Twelve-month VS rate on lopinavir/ritonavir-based ART was high, comparable to those in Africa or high-income countries. The father as the main child caregiver and lack of access to tap water are risk factors for viral failure and justify a special caution to improve adherence in these easy-to-identify situations before ART initiation. Public health challenges remain to optimize outcomes in children with earlier ART initiation in West Africa.

Abstract
In order to achieve optimal benefits of antiretroviral therapy (ART), caregivers of children receiving ART are required to attend routine clinic visits monthly and administer medication to the child as prescribed. Yet, the level of adherence to these behaviours varies considerably in many settings. As a way to achieve optimal adherence in rural KwaZulu-Natal, caregivers are required to attend routine counselling sessions at HIV treatment clinics that are centred on imparting information, motivation, and behavioural skills related to medication administration. According to the information-motivation-behavioural skills model, information related to adherence, motivation, and behavioural skills are necessary and fundamental determinants of adherence to ART. The purpose of the study was to observe and document the content of adherence counselling sessions that caregivers attending rural clinics in KwaZulu Natal receive. We observed 25 adherence counselling sessions, which lasted on average 8.1 minutes. Counselling typically consisted of counsellors recording patient attendance, reporting CD4 count and viral load results to caregivers, emphasising dose times, and asking caregivers to name their medications and dosage amounts. Patients were seldom asked to demonstrate how they measure the medication. They were also not probed for problems regarding treatment, even when an unsuppressed VL was reported to a caregiver. This paper calls attention to the sub-optimal level of counselling provided to patients on ART and the urgent need to standardise and improve the training, support, and debriefing provided to counsellors.

Pham MD, Romero L, Parnell B, Anderson DA, Crowe SM, Luchters S. Feasibility of antiretroviral treatment monitoring in the era of decentralized HIV care: a systematic review. AIDS Res Ther 2017; 14:3. [PMID: 28103895 PMCID: PMC5248527 DOI: 10.1186/s12981-017-0131-5] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Accepted: 01/06/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Regular monitoring of HIV patients who are receiving antiretroviral therapy (ART) is required to ensure patient benefits and the long-term effectiveness and sustainability of ART programs. Prompted by WHO recommendations for expansion and decentralization of HIV treatment and care in low and middle income countries, we conducted a systematic review to assess the feasibility of treatment monitoring in these settings. METHODS A comprehensive search strategy was developed using a combination of MeSH and free text terms relevant to HIV treatment and care, health service delivery, health service accessibility, decentralization and other relevant terms. Five electronic databases and two conference websites were searched to identify relevant studies conducted in LMICs, published in English between Jan 2006 and Dec 2015. Outcomes of interest included the proportion of patients who received treatment monitoring and health system factors related to monitoring of patients on ART under decentralized HIV service delivery models. RESULTS From 5363 records retrieved, twenty studies were included in the review; all but one was conducted in sub-Saharan African countries. The majority of studies (15/20) had relatively short follow-up duration (≤24 months), and only two studies were specifically designed to assess treatment monitoring practices. The most frequently studied follow-up period was 12 months and a wide range of treatment monitoring coverage was observed. The reported proportions of patients on ART who received CD4 monitoring ranged from very low (6%; N = 2145) to very high (95%; N = 488). The median uptake of viral load monitoring was 86% with studies in program settings reporting coverage as low as 14%. Overall, the longer the follow-up period, the lower the proportion of patients who received regular monitoring tests; and programs in rural areas reported low coverage of laboratory monitoring. Moreover, uptake in the context of research had significantly better where monitoring was done by dedicated research staff. In the absence of point of care (POC) testing, the limited capacity for blood sample transportation between clinic and laboratory and poor quality of nursing staff were identified as a major barrier for treatment monitoring practice. CONCLUSIONS There is a paucity of data on the uptake of treatment monitoring, particularly with longer-term follow-up. Wide variation in access to both virological and immunological regular monitoring was observed, with some clinics in well-resourced settings supported by external donors achieving high coverage. The feasibility of treatment monitoring, particularly in decentralized settings of HIV treatment and care may thus be of concern and requires further study. Significant investment in POC diagnostic technologies and, improving the quality of and training for nursing staff is required to ensure effective scale up of ART programs towards the targets of 90-90-90 by the year 2020.

Abstract
BACKGROUND In 2007, Swaziland initiated a hub-and-spoke model for decentralizing antiretroviral therapy (ART) access for HIV-infected children (<15 years old). Decentralization was facilitated through (1) down referral of stable children on ART from overburdened central facilities (hubs) to primary healthcare clinics (spokes) and (2) pediatric ART initiation at spokes (spoke initiation). METHODS We conducted a nationally representative retrospective cohort study among children starting ART during 2004-2010 to assess effect of down referral and spoke initiation on rates of loss to follow-up (LTFU), death and attrition (death or LTFU). Twelve of 28 pediatric ART hubs were randomly selected using probability-proportional-to-size sampling. Seven selected facilities had initiated hub-and-spoke decentralization by study start; at these facilities, 901 of 1893 hub-initiated and maintained (hub-maintained) children and 495 of 1105 down-referred or spoke-initiated children were randomly selected for record abstraction. At the 5 hub-only facilities, 612 of 1987 children were randomly selected. Multivariable proportional hazards regression was used to estimate adjusted hazard ratios (AHR) for effect of down referral (a time-varying covariate) and spoke initiation on outcomes. RESULTS Among 2008 children at ART initiation, median age was 5.0 years, median CD4% 12.0%, median CD4 count 358 cells/µL and median weight-for-age Z score -1.91. Controlling for known confounders, down referral was strongly protective against LTFU (AHR: 0.40; 95% confidence interval: 0.20-0.79) and attrition (AHR: 0.46; 95% confidence interval: 0.26-0.83) but not mortality. Compared with hub-only children or hub-maintained children, spoke-initiated children had similar outcomes. CONCLUSIONS Decentralization of pediatric ART through down referral and spoke initiation within a hub-and-spoke system should be continued and might improve program outcomes.

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

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

Abstract
BACKGROUND Little is known about the long-term outcome of antiretroviral therapy (ART) for children with advanced-stage HIV. AIM To assess the outcome in children with advanced HIV initiated on ART. The predictors for survival, general wellbeing and the role of palliative care were assessed. METHODS Patient files, retained patient records and personal follow-up were used for data collection. Data on baseline characteristics, ART treatment and progress were collected at baseline, 6, 12 and 48 months. Information regarding general wellbeing and school attendance and performance were collected. RESULTS 37 children were started on ART. At 48 months there were 18 known survivors and 7 known to have died. Another 12 were transferred to another programme or lost to follow-up. There was no significant difference in baseline characteristics between groups. All eligible children attended school and all received medical care. The hospice programme offered holistic care and support. CONCLUSIONS No baseline characteristic could predict the outcome of children with advanced HIV initiated on ART. A hospice support programme can contribute to positive outcomes even when ART is initiated in children with advanced disease.

Infect Dis Poverty 2015; 4:18. [PMID: 25954505 PMCID: PMC4423522 DOI: 10.1186/s40249-015-0049-x] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2014] [Accepted: 04/01/2015] [Indexed: 11/22/2022] Open
Abstract
Background Provider-initiated HIV testing and counseling (PITC) is offered as part of the normal standard of care to increase access to treatment for HIV-infected children. In practice, HIV diagnosis occurs in late childhood following recurrent and chronic infections. We investigated primary caregivers’ reported reasons for seeking HIV testing for children aged 5–18 years, determined the orphan status of the children, and compared the clinical profile and disease burden of orphans and non-orphans. Methods This was a cross-sectional survey of primary caregivers of HIV-infected children accessing antiretroviral treatment (ART) from two community hospitals and 34 primary healthcare facilities in a rural district in Mpumalanga province, South Africa. Results The sample consisted of 406 primary caregivers: 319 (78.6%) brought the child to the health facility for HIV testing because of chronic and recurrent infections. Almost half (n = 183, 45.1%) of the children were maternal orphans, 128 (31.5%) were paternal orphans, and 73 (39.9%) were double orphans. A univariate analysis showed that maternal orphans were significantly more likely to be older (OR = 2.57, p = 0.000, CI: 1.71–3.84), diagnosed late (OR = 2.48, p = 0.009, CI: 1.26–4.88), and to start ART later (OR = 2.5, p = 0.007, CI: 1.28–4.89) than non-orphans. There was a high burden of infection among the children prior to HIV diagnosis; 274 (69.4%) presented with multiple infections. Multiple logistic regression showed that ART start age (aOR = 1.19, p = 0.000, CI: 1.10–1.29) and time on ART (aOR = 2.30, p = 0.000, CI: 1.45–3.64) were significantly associated with orphanhood status. Half (n = 203, (50.2%) of the children were admitted to hospital prior to start of ART, and hospitalization was associated with multiple infections (OR = 1.27, p = 0.004, CI: 1.07–1.51). Conclusions The study found late presentation with undiagnosed perinatal HIV infection and high prevalence of orphanhood among the children. The health of maternal orphans was more compromised than non-orphans. Routine PICT should be strengthened to increase community awareness about undiagnosed HIV among older children and to encourage primary caregivers to accept HIV testing for children.

Abstract
OBJECTIVES There are several published systematic reviews of adult retention in care after antiretroviral therapy (ART) initiation among adults, but limited information on pediatric retention. DESIGN Systematic review of pediatric retention on ART in low and middle-income countries during 2008-2013. METHODS We estimated all-cause attrition (death and loss to follow-up) and retention for pediatric patients receiving first-line ART in routine settings. We searched PubMed, Embase, Cochrane Register, and ISI Web of Science (January 2008-January 2014) and abstracts from AIDS and IAS (2008-2013). We estimated mean retention across cohorts using simple averages; interpolated any time period not reported to, up to the last period reported; summarized total retention in the population using Kaplan-Meier survival curves; and compared pediatric to adult retention. RESULTS We found 39 reports of retention in 45 patient cohorts and 55 904 patients in 23 countries. Among them, 37% of patients not retained in care were known to have died and 63% were lost to follow-up. Unweighted averages of reported retention were 85, 81, and 81% at 12, 24, and 36 months after ART initiation. From life-table analysis, we estimated retention at 12, 24, and 36 months at 88, 72, and 67%. We estimated 36-month retention at 66% in Africa and 74% in Asia. CONCLUSION Pediatric ART retention was similar to that among adults. There were limited data from Asia, only one study from Latin America and the Caribbean, and no data from Eastern Europe, Central Asia, or the Middle East.

Abstract
Introduction L'objectif de ce travail était d’évaluer l'impact du traitement antirétroviral sur le profil biologique des enfants VIH positifs suivis au Centre Hospitalier et Universitaire de Yaoundé au Cameroun. Méthodes Il s'agissait d'une étude rétrospective réalisée de Mai 2003 à Décembre 2012 au CHU de Yaoundé au Cameroun. Pour cette étude, nous avons obtenu une clairance éthique. Résultats L’âge moyen était de 54.02±46.34 mois. The sexe ratio était de 0.96 en faveur des garçons. Le diagnostic s’était fait tardivement (74.2%) ainsi que la mise sous traitement (83.3%). Seuls 36 des 116 enfants (31%) avait pu avoir un bilan biologique à l'initiation du traitement antirétroviral et six mois après l'initiation du traitement antirétroviral. Après six mois de traitement, nous avons enregistrés une augmentation significative des paramètres biologiques suivants: taux de glycémie de 0.09g/L (0.75-0.84; p= 0.007), pourcentage de CD4 chez les enfants de moins de 5 ans de 4.62% (20.12-24.75; p = 0.022), valeur absolue de CD4 chez les enfants de plus de 5 ans de 294 cellules/mm3 (151.18-445.18; p = 0.011), le rapport CD4/CD8 de 0.35 (0.55-0.90; p = 0.000). Enfin, après six mois de traitement, on enregistrait une baisse significative de la charge virale du VIH de 3.90 log (5.85-1.95; p = 0.006). Conclusion Il ressort de cette étude que la restauration immunitaire et la suppression virologique peuvent être obtenus après six mois de traitement antirétroviral. Cependant, des efforts doivent encore être faits en ce qui concerne la prise en charge du suivi biologique, gage d'un bon suivi thérapeutique au Cameroun.

Abstract
Poor adherence to antiretroviral therapy (ART) contributes to the development of drug resistance. HIV-infected children, especially those 5 years and under, are dependent on a caregiver to adhere to ART. However, characteristics of the caregiver, child, regimen, clinic and social context affect clinic attendance and medication-taking, both of which constitute adherent behaviour. We conducted nine interviews and three focus groups to determine how doctors, nurses, counsellors, traditional healers and caregivers understood the barriers and facilitators to ART adherence among children residing in rural South Africa. The data were transcribed, translated into English from isiZulu where necessary, and coded using Atlas.ti version 7. Results were interpreted through the lens of Bronfenbrenner's Ecological Systems Theory. We found that at the micro-level, palatability of medication and large volumes of medication were problematic for young children. Characteristics of the caregiver including absent mothers, grandmothers as caregivers and denial of HIV amongst fathers were themes related to the micro-system. Language barriers and inconsistent attendance of caregivers to monthly clinic visits were factors affecting adherence in the meso-system. Adherence counselling and training were the most problematic features in the exo-system. In the macro-system, the effects of food insecurity and the controversy surrounding the use of traditional medicines were most salient. Increased supervision and regular training amongst lay adherence counsellors are needed, as well as regular monitoring of the persons attending the clinic on the child's behalf.

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.

van Dijk JH, Moss WJ, Hamangaba F, Munsanje B, Sutcliffe CG. Scaling-up access to antiretroviral therapy for children: a cohort study evaluating care and treatment at mobile and hospital-affiliated HIV clinics in rural Zambia. PLoS One 2014; 9:e104884. [PMID: 25122213 PMCID: PMC4133342 DOI: 10.1371/journal.pone.0104884] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2014] [Accepted: 07/17/2014] [Indexed: 11/19/2022] Open
Abstract
Background Travel time and distance are barriers to care for HIV-infected children in rural sub-Saharan Africa. Decentralization of care is one strategy to scale-up access to antiretroviral therapy (ART), but few programs have been evaluated. We compared outcomes for children receiving care in mobile and hospital-affiliated HIV clinics in rural Zambia. Methods Outcomes were measured within an ongoing cohort study of HIV-infected children seeking care at Macha Hospital, Zambia from 2007 to 2012. Children in the outreach clinic group received care from the Macha HIV clinic and transferred to one of three outreach clinics. Children in the hospital-affiliated clinic group received care at Macha HIV clinic and reported Macha Hospital as the nearest healthcare facility. Results Seventy-seven children transferred to the outreach clinics and were included in the analysis. Travel time to the outreach clinics was significantly shorter and fewer caretakers used public transportation, resulting in lower transportation costs and fewer obstacles accessing the clinic. Some caretakers and health care providers reported inferior quality of service provision at the outreach clinics. Sixty-eight children received ART at the outreach clinics and were compared to 41 children in the hospital-affiliated clinic group. At ART initiation, median age, weight-for-age z-scores (WAZ) and CD4+ T-cell percentages were similar for children in the hospital-affiliated and outreach clinic groups. Children in both groups experienced similar increases in WAZ and CD4+ T-cell percentages. Conclusions HIV care and treatment can be effectively delivered to HIV-infected children at rural health centers through mobile ART teams, removing potential barriers to uptake and retention. Outreach teams should be supported to increase access to HIV care and treatment in rural areas.

Abstract
Objective This qualitative study explored the views and experiences of adolescents with perinatally acquired HIV in Kigali, Rwanda, regarding sex, love, marriage, children and hope for the future. Design The study enrolled 42 adolescents who had received combination antiretroviral therapy for at least 12 months, and a selection of their primary caregivers. Study methods included 3 multiple day workshops consisting of role-playing and focus group discussions (FGDs) with adolescents, 8 in-depth interviews with adolescents, and one FGD with caregivers. Results The adolescents reported experiencing similar sexual needs and dilemmas as most other adolescents, but with an added layer of complexity due to fears related to HIV transmission and/or rejection by partners. They desired more advice from their parents/caregivers on these topics. Although they struggled with aspects of sex, love, marriage and having children, most agreed that they would find love, be married and have children in the future. The two most discussed HIV-related anxieties were how and when to disclose to a (potential) sex/marriage partner and whether to have children. However, most adolescents felt that they had a right to love and be loved, and were aware of prevention-of-mother-to-child-transmission (PMTCT) options in Rwanda. Adolescents generally spoke about their future role in society in a positive manner. Conclusion Strengthening the life skills of HIV-positive adolescents, especially around HIV disclosure and reduction of HIV transmission, as well as the support skills of parents/caregivers, may not only reduce onward HIV transmission but also improve quality of life by reducing anxiety.

Abstract
Objectives Based on the important changes in South Africa since 2009 and the Antiretroviral Treatment Guideline 2013 recommendations, we explored the cost-effectiveness of different strategy combinations according to the South African HIV-infected mothers' prompt treatments and different feeding patterns. Study Design A decision analytic model was applied to simulate cohorts of 10,000 HIV-infected pregnant women to compare the cost-effectiveness of two different HIV strategy combinations: (1) Women were tested and treated promptly at any time during pregnancy (Promptly treated cohort). (2) Women did not get testing or treatment until after delivery and appropriate standard treatments were offered as a remedy (Remedy cohort). Replacement feeding or exclusive breastfeeding was assigned in both strategies. Outcome measures included the number of infant HIV cases averted, the cost per infant HIV case averted, and the cost per life year(LY) saved from the interventions. One-way and multivariate sensitivity analyses were performed to estimate the uncertainty ranges of all outcomes. Results The remedy strategy does not particularly cost-effective. Compared with the untreated baseline cohort which leads to 1127 infected infants, 698 (61.93%) and 110 (9.76%) of pediatric HIV cases are averted in the promptly treated cohort and remedy cohort respectively, with incremental cost-effectiveness of $68.51 and $118.33 per LY, respectively. With or without the antenatal testing and treatments, breastfeeding is less cost-effective ($193.26 per LY) than replacement feeding ($134.88 per LY), without considering the impact of willingness to pay. Conclusion Compared with the prompt treatments, remedy in labor or during the postnatal period is less cost-effective. Antenatal HIV testing and prompt treatments and avoiding breastfeeding are the best strategies. Although encouraging mothers to practice replacement feeding in South Africa is far from easy and the advantages of breastfeeding can not be ignored, we still suggest choosing replacement feeding as far as possible.

Abstract
Despite expansion of services for prevention of mother-to-child transmission of HIV (PMTCT), about 700 infants acquire HIV every day. Early initiation of antiretroviral therapy for HIV-infected infants reduces mortality but requires diagnosis by virological testing, which is complex, expensive, and inaccessible in many settings. Little cost-effectiveness evidence exists about different strategies to deliver early infant diagnosis services. Cost-effectiveness will vary depending on entry points for testing, underlying prevalences of HIV, PMTCT coverage, treatment availability, programme attrition, and other factors. Appropriate policy responses are therefore context-specific. In most cases, early infant diagnosis should be concentrated at entry points where underlying infant HIV prevalence is highest (eg, malnutrition wards). This strategy contrasts with the tendency at present to test mainly within PMTCT programmes. If testing is undertaken in PMTCT programmes with high coverage, addition of a virological test at birth might have advantages, including greater predictive value, earlier diagnosis, and better infant follow-up. National programme managers should recognise the opportunity costs of the limited resources available, acknowledge the changing scenario of PMTCT scale-up, ensure implementation of provider-initiated testing and counselling, and tailor early infant diagnosis programmes to maximise health gains for children.

Abstract
BACKGROUND Pediatric antiretroviral treatment coverage in resource-limited settings continues to lag behind adults. Task shifting is an effective approach broadly used for adults, which some countries have also adopted for children, but implementation is limited by lack of confidence and skills among nonspecialist staff. METHODS A systematic review was conducted by combining key terms for task shifting, antiretroviral therapy (ART), and children. Five databases and two conferences were searched from inception till August 01, 2013. RESULTS Eight observational studies provided outcome data for 11,828 children who received ART from nonphysician providers across 10 countries in sub-Saharan Africa. The cumulative pooled proportion of deaths was 3.2% [95% confidence interval (CI): 2.0 to 4.5] at 6 months, 4.6% (95% CI: 2.1 to 7.1) at 12 months, 6.2% (95% CI: 3.7 to 8.8) at 24 months, and 5.9% (95% CI: 3.5 to 8.3) at 36 months. Mortality and loss to follow-up in task-shifting programs were comparable to those reported by programs providing doctor- or specialist-led care. CONCLUSIONS Our review suggests that task shifting of ART care can result in outcomes comparable to routine physician care, and this approach should be considered as part of a strategy to scale-up pediatric treatment. Specialist care will remain important for management of sick patients and complicated cases. Further qualitative research is needed to inform optimal implementation of task shifting for pediatric patients.

Abstract
Background Better understanding of drug resistance patterns in HIV-infected children on antiretroviral therapy (ART) is required to inform public health policies in high prevalence settings. The aim of this study was to characterise the acquired drug resistance in HIV-infected children failing first-line ART in a decentralised rural HIV programme. Methods Plasma samples were collected from 101 paediatric patients (≤15 yrs of age) identified as failing ART. RNA was extracted from the plasma, reverse transcribed and a 1.3 kb region of the pol gene was amplified and sequenced using Sanger sequencing protocols. Sequences were edited in Geneious and drug resistance mutations were identified using the RegaDB and the Stanford resistance algorithms. The prevalence and frequency of mutations were analysed together with selected clinical and demographic data in STATA v11. Results A total of 101 children were enrolled and 89 (88%) were successfully genotyped; 73 on a non-nucleoside reverse-transcriptase inhibitor (NNRTI)-based regimen and 16 on a protease inhibitor (PI)-based regimen at the time of genotyping. The majority of patients on an NNRTI regimen (80%) had both nucleoside reverse-transcriptase inhibitor (NRTI) and NNRTI resistance mutations. M184V and K103N were the most common mutations amongst children on NNRTI-based and M184V among children on PI-based regimens. 30.1% had one or more thymidine analogue mutation (TAM) and 6% had ≥3 TAMs. Only one child on a PI-based regimen harboured a major PI resistance mutation. Conclusions Whilst the patterns of resistance were largely predictable, the few complex resistance patterns seen with NNRTI-based regimens and the absence of major PI mutations in children failing PI-based regimens suggest the need for wider access to genotypic resistance testing in this setting.

Abstract
BACKGROUND Since 2005, increasing numbers of children have started antiretroviral therapy (ART) in sub-Saharan Africa and, in recent years, WHO and country treatment guidelines have recommended ART initiation for all infants and very young children, and at higher CD4 thresholds for older children. We examined temporal changes in patient and regimen characteristics at ART start using data from 12 cohorts in 4 countries participating in the IeDEA-SA collaboration. METHODOLOGY/PRINCIPAL FINDINGS Data from 30,300 ART-naïve children aged <16 years at ART initiation who started therapy between 2005 and 2010 were analysed. We examined changes in median values for continuous variables using the Cuzick's test for trend over time. We also examined changes in the proportions of patients with particular disease severity characteristics (expressed as a binary variable e.g. WHO Stage III/IV vs I/II) using logistic regression. Between 2005 and 2010 the number of children starting ART each year increased and median age declined from 63 months (2006) to 56 months (2010). Both the proportion of children <1 year and ≥10 years of age increased from 12 to 19% and 18 to 22% respectively. Children had less severe disease at ART initiation in later years with significant declines in the percentage with severe immunosuppression (81 to 63%), WHO Stage III/IV disease (75 to 62%), severe anemia (12 to 7%) and weight-for-age z-score<-3 (31 to 28%). Similar results were seen when restricting to infants with significant declines in the proportion with severe immunodeficiency (98 to 82%) and Stage III/IV disease (81 to 63%). First-line regimen use followed country guidelines. CONCLUSIONS/SIGNIFICANCE Between 2005 and 2010 increasing numbers of children have initiated ART with a decline in disease severity at start of therapy. However, even in 2010, a substantial number of infants and children started ART with advanced disease. These results highlight the importance of efforts to improve access to HIV diagnostic testing and ART in children.

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
Treatment 2.0 is an initiative launched by UNAIDS and WHO in 2011 to catalyze the next phase of treatment scale-up for HIV. The initiative defines strategic activities in 5 key areas, drugs, diagnostics, commodity costs, service delivery and community engagement in an effort to simplify treatment, expand access and maximize program efficiency. For adults, many of these activities have already been turned into treatment policies. The recent WHO recommendation to use a universal first line regimen regardless of gender, pregnancy and TB status is a treatment simplification very much in line with Treatment 2.0. But despite that fact that Treatment 2.0 encompasses all people living with HIV, we have not seen the same evolution in policy development for children. In this paper we discuss how Treatment 2.0 principles can be adapted for the pediatric population. There are several intrinsic challenges. The need for distinct treatment regimens in children of different ages makes it hard to define a one size fits all approach. In addition, the fact that many providers are reluctant to treat children without the advice of specialists can hamper decentralization of service delivery. But at the same time, there are opportunities that can be availed now and in the future to scale up pediatric treatment along the lines of Treatment 2.0. We examine each of the five pillars of Treatment 2.0 from a pediatric perspective and present eight specific action points that would result in simplification of pediatric treatment and scale up of HIV services for children.

Abstract
BACKGROUND Efforts to scale-up HIV treatment in high burden countries have resulted in wider access to care, improved survival and decreased morbidity for HIV-infected children. The country of Rwanda has made significant achievements in expanding coverage of pediatric HIV services. METHODS We describe the extent of and factors associated with mortality and lost to follow-up (LTF) in children (<15 years) enrolled in HIV care at 39 ICAP-supported facilities across Rwanda from 2004 to 2010 by antiretroviral treatment (ART) status. We estimated the 1-year cumulative incidence of death and LTF among all children enrolled in care (pre-ART) and children on ART. Survival analysis was used to evaluate factors associated with death and LTF in both groups. RESULTS Between January 2004 and June 2010, 3244 children with a median age of 5.7 years (interquartile range 2.8-9.6) enrolled in HIV care. One-year cumulative incidence for death and LTF among pre-ART children was 4% (95% confidence interval [CI]: 3-5%) and 5% (95% CI: 4-6%), respectively. Overall, 2035 (63%) children initiated ART, median age 6.3 years (interquartile range 3.3-10.4): 1-year Kaplan-Meier estimates of death and LTF were 3% (95% CI: 3-4%) and 1% (95% CI: 1-2%), respectively. Factors associated with an increased hazard for death among pre-ART children included being <18 months old versus ≥5 years (adjusted sub hazard ratio [aSHR] = 4.4, 95% CI: 2.9-6.8) and World Health Organization stage IV versus I (aSHR = 4.1, 95% CI: 2.0-8.4), whereas children entering care through prevention of mother-to-child transmission had lower hazard than those from voluntary counseling and testing (aSHR = 0.50, 95% CI: 0.25-1.0). Markers of advanced disease, including severe immunosuppression (aSHR = 0.25, 95% CI: 0.12-0.54), and enrollment in care in rural versus urban clinics (aSHR = 0.71, 95% CI: 0.53-0.97) were protective against LTF. For children on ART, factors associated with hazard of death included younger age (adjusted hazard ratio [aHR] <18 months versus ≥5 years = 2.1, 95% CI: 1.3-3.6), severe malnutrition versus not malnourished (aHR = 3.2, 95% CI: 1.3-8.1), advanced World Health Organization stage (aHR IV versus I = 9.8, 95% CI: 3.5-27.4) and severe immunodeficiency versus no evidence (aHR = 2.3, 95% CI: 1.7-3.3). No associations were observed with LTF among children on ART. CONCLUSIONS The results demonstrate very high retention among children enrolled in HIV care in Rwanda. Younger children continue to be particularly vulnerable, underscoring the urgent need for early identification, rapid treatment initiation and long-term retention in care.

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

Abstract
BACKGROUND In resource-limited settings, decentralization of HIV care and treatment is a cornerstone of universal care and rapid scale-up. We compared trends in pediatric enrollment and outcomes at primary (PHFs) vs secondary/tertiary health facilities (SHFs). METHODS Using aggregate program data reported quarterly from 274 public facilities in Kenya, Lesotho, Mozambique, Rwanda, and Tanzania from January 2008 to March 2010, we examined trends in number of children younger than 15 years of age initiating antiretroviral treatment (ART) by facility type. We compared clinic-level lost to follow-up (LTFU) and mortality per 100 person-years (PYs) on ART during the period by facility type. RESULTS During the 2-year period, 17,155 children enrolled in HIV care and 8475 initiated ART in 182 (66%) PHFs and 92(34%) SHFs. PHFs increased from 56 to 182, whereas SHFs increased from 72 to 92 sites. SHFs accounted for 71% of children initiating ART; however, the proportion of children initiating ART each quarter at PHFs increased from 17% (129) to 44% (463) in conjunction with an increase in PHFs during observation period. The average LTFU and mortality rates for children on ART were 9.8/100 PYs and 5.2/100 PYs, respectively, at PHFs and 20.2/100 PYs and 6.0/100 PYs, respectively, at SHFs. Adjusted models show PHFs associated with lower LTFU (adjusted rate ratio = 0.55; P = 0.022) and lower mortality (adjusted rate ratio = 0.66; P = 0.028). CONCLUSIONS The expansion of pediatric services to PHFs has resulted in increased numbers of children on ART. Early findings suggest lower rates of LTFU and mortality at PHFs. Successful scale-up will require further expansion of pediatric services within PHFs.

Abstract
Background Antiretroviral therapy (ART) is known to save lives. Among HIV-infected infants living in resource constrained settings, the short and long term benefits of ART are only partially known. This study was designed to determine the virologic, immunologic and clinical outcomes of antiretroviral therapy in a cohort of HIV-infected infants receiving care from an outpatient clinic in Kampala, Uganda. Methods A prospective cohort of HIV-infected infants receiving treatment at the Baylor-Uganda clinic was analyzed. Patients were diagnosed, enrolled and followed up at the clinic. HIV viral load, CD4 cell counts and clinical progress were assessed during follow-up. Descriptive statistical analysis and logistic regression modeling to determine predictors of treatment success were conducted. Results Of 91 HIV-infected infants enrolled into the cohort, 53 (58.2%) infants were female; 43 (47.3%) were 6 months of age or younger, and 50 (55.6%) had advanced HIV/AIDS disease (Clinical stage 3 or 4). Eighty four infants started ART and 78 (92.9%) completed 6 months of treatments. Fifty six (71.8%) infants attained virologic suppression by month-6 of ART, and at month-12 of ART, the cumulative probability of attaining viral suppression was 83.1%. None of the baseline infant factors (age, sex, WHO stage, CD4 cell percent, weight for age, or height for age z-score) predicted treatment success. There was an increase in CD4 cells from a baseline mean of 23% to 30% at month-6 of treatment (p<0.001) and by month-24 of ART, the mean CD4 percent was 36%. A total of 7 patients died while on ART and another 7 experienced adverse events that were related to treatment. Conclusion Our results show that, even among very young patients from resource constrained settings, ART dramatically suppresses HIV replication, allows immune recovery and clinical improvement, and is safe. However, baseline characteristics do not predict recovery in this age group.

Young children's probability of dying before and after their mother's death: a rural South African population-based surveillance study. PLoS Med 2013; 10:e1001409. [PMID: 23555200 PMCID: PMC3608552 DOI: 10.1371/journal.pmed.1001409] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2012] [Accepted: 02/14/2013] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND There is evidence that a young child's risk of dying increases following the mother's death, but little is known about the risk when the mother becomes very ill prior to her death. We hypothesized that children would be more likely to die during the period several months before their mother's death, as well as for several months after her death. Therefore we investigated the relationship between young children's likelihood of dying and the timing of their mother's death and, in particular, the existence of a critical period of increased risk. METHODS AND FINDINGS Data from a health and socio-demographic surveillance system in rural South Africa were collected on children 0-5 y of age from 1 January 1994 to 31 December 2008. Discrete time survival analysis was used to estimate children's probability of dying before and after their mother's death, accounting for moderators. 1,244 children (3% of sample) died from 1994 to 2008. The probability of child death began to rise 6-11 mo prior to the mother's death and increased markedly during the 2 mo immediately before the month of her death (odds ratio [OR] 7.1 [95% CI 3.9-12.7]), in the month of her death (OR 12.6 [6.2-25.3]), and during the 2 mo following her death (OR 7.0 [3.2-15.6]). This increase in the probability of dying was more pronounced for children whose mothers died of AIDS or tuberculosis compared to other causes of death, but the pattern remained for causes unrelated to AIDS/tuberculosis. Infants aged 0-6 mo at the time of their mother's death were nine times more likely to die than children aged 2-5 y. The limitations of the study included the lack of knowledge about precisely when a very ill mother will die, a lack of information about child nutrition and care, and the diagnosis of AIDS deaths by verbal autopsy rather than serostatus. CONCLUSIONS Young children in lower income settings are more likely to die not only after their mother's death but also in the months before, when she is seriously ill. Interventions are urgently needed to support families both when the mother becomes very ill and after her death. Please see later in the article for the Editors' Summary.

Abstract
From 2006 to 2011, a cohort study was conducted among 1000 children resident in urban and rural settings of Uganda to ascertain and compare the response to antiretroviral therapy (ART) among urban versus rural children and the factors associated with this response. Clinical, immunological, and virological parameters were ascertained at baseline and weeks 24, 48, 96, and 144 after ART initiation. Adherence to ART was assessed at enrollment by self-report (SR) and pill counts (PC). Overall, 499/948 (52.6%) children were resident in rural areas, 504/948 (53.1%) were male, and their mean age was 11.9±4.4 years (urban children) and 11.4±4.1 years (rural children). The urban children were more likely to switch to second-line ART at a rate of 39.9 per 1000 person-years (95% CI: 28.2-56.4) versus 14.9 per 1000 person-years (95% CI: 8.7-25.7), p=0.0038, develop any new WHO 3/4 events at 127/414 (30.7%) versus 108/466 (23.2%), p=0.012, and have a higher cumulative incidence of hospitalization of 54/449 (12.0%) versus 32/499 (6.4%), p=0.003, when compared to rural children. No differences were observed in mean changes in weight, height, CD4 count and percentage, and hemoglobin and viral load between urban and rural children. Adherence of ≥95% was observed in 88.2% of urban versus 91.3% of rural children by SR (p=0.130), and in 78.8% of urban versus 88.8% of rural children by PC (p<0.0001). In this study rural children had more favorable clinical outcomes and were more likely to adhere optimally to ART than urban children.

Abstract
BACKGROUND We reviewed the impact of HIV, HIV exposure, and antiretroviral therapy/prophylaxis on neurodevelopmental outcomes of HIV-infected and HIV-exposed-uninfected infants and children. METHODS A literature search of Medline, Embase, PsychINFO, Web of Science, PubMed, and conference Web sites (1990-March 2011) using the search terms, infant, child, HIV, neurodevelopment, cognition, language, and antiretroviral therapy, identified 31 studies of HIV/antiretroviral exposure using standardized tools to evaluate infant/child development as the main outcome. Articles were included if results were reported in children <16 years of age who were exposed to HIV and antiretrovirals in fetal/early life, and excluded if children did not acquire HIV from their mothers or were not exposed to antiretrovirals in fetal/early life. RESULTS Infants who acquired HIV during fetal and early life tended to display poorer mean developmental scores than HIV-unexposed children. Mean motor and cognitive scores were consistently 1 to 2 SDs below the population mean. Mean scores improved if the infant received treatment before 12 weeks and/or a more complex antiretroviral regimen. Older HIV-infected children treated with highly active antiretroviral therapy demonstrated near normal global mean neurocognitive scores; subtle differences in language, memory, and behavior remained. HIV-exposed-uninfected children treated with antiretrovirals demonstrated subtle speech and language delay, although not universally. CONCLUSIONS In comparison with resource-rich settings, HIV-infected and HIV-exposed-uninfected infants/children in resource-poor settings demonstrated greater neurodevelopmental delay compared with HIV-unexposed infants. The effects on neurodevelopment in older HIV-infected children commenced on antiretroviral therapy from an early age and HIV-exposed-uninfected children particularly in resource-poor settings remain unclear.

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

Abstract
HIV/AIDS has had a profound impact on children around the world since the start of the epidemic. There are currently 3.4 million children under the age of 15 years living with HIV globally, and more than 450,000 children currently receiving lifesaving antiretroviral treatment. This article describes efforts supported by the President's Emergency Plan for AIDS Relief (PEPFAR) to expand access to treatment for children living with HIV in high-burden countries. The article also highlights a series of case studies that illustrate the impact that the PEPFAR initiative has had on the pediatric HIV epidemic. Through its support of host governments and partner organizations, the PEPFAR initiative has expanded HIV testing and treatment for pregnant women to reduce vertical transmission of HIV, increased access to early infant diagnosis for HIV-exposed infants, improved training and resources for clinicians who provide pediatric care and antiretroviral treatment, and, through public-private partnerships with pharmaceutical manufacturers, helped increase the number of medications available for the treatment of HIV-infected children in resource-limited settings.

Abstract
BACKGROUND Maternal and child survival are highly correlated, but the contribution of HIV infection on this relationship, and in particular the effect of HIV treatment, has not been quantified. We estimate the association between maternal HIV and treatment, and under 5 years of age (under-5) child mortality in a rural population in South Africa. METHODS All children born between January 2000 and January 2007 in the Africa Centre Demographic Surveillance Area were included. Maternal HIV status information was available from HIV surveillance; maternal antiretroviral treatment (ART) information from the HIV Treatment Programme database was linked to surveillance data. Mortality rates were computed as deaths per 1,000 person-years observed. Time-varying maternal HIV effect (positive, negative, ART) on under-5 mortality was assessed in Cox regression, adjusting for other factors associated with under-5 mortality. RESULTS In total, 9,068 mothers delivered 12,052 children, of whom 947 (7.9%) died before age 5. Infant mortality rate declined by 49% from 69.0 in 2000 to 35.5 in 2006 deaths per 1,000 person-years observed; a significant decline was observed post-ART (2004-2006). The estimated proportion of deaths across all age groups were higher among the children born to the HIV-positive and HIV-not-reported status women than among children of HIV-negative women. Multivariably, mortality in children of mothers on ART was not significantly different from children of HIV-negative mothers (adjusted hazard ratio 1.29, 0.53-3.17; P=0.572). CONCLUSIONS These findings highlight the importance of maternal HIV treatment with direct benefits of improved survival among all children under-5. Timely HIV treatment for eligible women is required to benefit both mothers and children.

Abstract
BACKGROUND Few studies describe temporal trends in pediatric antiretroviral treatment (ART) programs in sub-Saharan Africa. Adult studies show deteriorating patient retention in recent years. We describe temporal trends in baseline characteristics and treatment outcomes amongst ART-naive children between 2004 and 2009 at 30 facilities in 4 South African provinces. METHODS Linear trend in baseline parameters between annual enrolment cohorts was assessed. Corrected mortality estimates were calculated, correcting for deaths amongst those lost to follow-up using probability-weighted Kaplan-Meier functions. On-treatment immunologic changes were modelled using generalized estimating equations. RESULTS Three thousand and seven children (median age 6.4 years) were included. Monthly enrollment increased from 1.9 children in 2004 to 106 in 2009. Proportions with severe baseline immunodeficiency decreased from 85.5% to 64.5% between 2004/2005 and 2009, P < 0.0005. Proportions with baseline World Health Organization clinical stages III and IV reduced from 72.9% to 49.0% between 2006 and 2009, P < 0.0005. Later calendar cohorts had independently and progressively reduced on-treatment probabilities of severe immunodeficiency despite adjusting for baseline immunological status, adjusted odds ratio: 0.38 [confidence interval (CI): 0.26 to 0.55; P < 0.0005; 2008/2009 compared with 2004/2005]. After 24 months, corrected mortality was 6.1% (CI: 5.1% to 7.3%) and loss to follow-up was 6.8% (CI: 5.7% to 8.2%), with no deterioration amongst more recently enrolled cohorts (P = 0.50 and P = 0.55, respectively). After 4 years, program retention was 84.1% (CI: 80.9% to 86.7%). CONCLUSIONS Childrens' baseline condition when starting ART has improved considerably. Improving immunological treatment outcomes, the high medium-term patient retention with lack of temporal deterioration despite rapid patient number increases, provide evidence that pediatric ART programs are increasingly effective for those accessing them. However, children must start treatment when younger, following current international guidelines.

Abstract
This article provides a summary of emerging psychosocial evidence relevant to the success of comprehensive family-centered approaches to HIV prevention, treatment, care and support programs in poorly resourced settings. This report synthesizes current evidence on maternal, paternal and family experiences of HIV prevention, diagnosis, treatment, adherence and disclosure, with special focus on HIV-infected mothers and HIV-exposed children. Taking a developmental approach, we explore the current challenges and opportunities towards a family-centered approach within the continuum of HIV treatment and care, beginning in pregnancy and following the course of childhood. The discussion is limited to early and middle childhood and excludes discussion of special issues emergent in adolescence, which would warrant discussion outside the scope of this article. Attention is drawn to the complexity of problems arising within the family context and the need for improvements in the integration of aspects of treatment, care and support. While this article focuses on examples from sub-Saharan Africa, the lessons learnt and future challenges outlined are applicable to most low- and middle-income countries, and to poorly resourced contexts in higher-income countries.

HIV-infected children in rural Zambia achieve good immunologic and virologic outcomes two years after initiating antiretroviral therapy. PLoS One 2011; 6:e19006. [PMID: 21552521 PMCID: PMC3084269 DOI: 10.1371/journal.pone.0019006] [Citation(s) in RCA: 57] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2010] [Accepted: 03/24/2011] [Indexed: 12/02/2022] Open
Abstract
Background Many HIV-infected children in sub-Saharan Africa reside in rural areas, yet most research on treatment outcomes has been conducted in urban centers. Rural clinics and residents may face unique barriers to care and treatment. Methods A prospective cohort study of HIV-infected children was conducted between September 2007 and September 2010 at the rural HIV clinic in Macha, Zambia. HIV-infected children younger than 16 years of age at study enrollment who received antiretroviral therapy (ART) during the study were eligible. Treatment outcomes during the first two years of ART, including mortality, immunologic status, and virologic suppression, were assessed and risk factors for mortality and virologic suppression were evaluated. Results A total of 69 children entered the study receiving ART and 198 initiated ART after study enrollment. The cumulative probabilities of death among children starting ART after study enrollment were 9.0% and 14.4% at 6 and 24 months after ART initiation. Younger age, higher viral load, lower CD4+ T-cell percentage and lower weight-for-age z-scores at ART initiation were associated with higher risk of mortality. The mean CD4+ T-cell percentage increased from 16.3% at treatment initiation to 29.3% and 35.0% at 6 and 24 months. The proportion of children with undetectable viral load increased to 88.5% and 77.8% at 6 and 24 months. Children with longer travel times (≥5 hours) and those taking nevirapine at ART initiation, as well as children who were non-adherent, were less likely to achieve virologic suppression after 6 months of ART. Conclusions HIV-infected children receiving treatment in a rural clinic experienced sustained immunologic and virologic improvements. Children with longer travel times were less likely to achieve virologic suppression, supporting the need for decentralized models of ART delivery.

Abstract
OBJECTIVE More than half the world's population lives in rural areas; however, we have limited evidence about how to strengthen rural healthcare services. We sought to determine the impact of a systems-based approach to improving rural care, the Ethiopian Millennium Rural Initiative, on key healthcare services indicators. DESIGN We conducted an 18-month longitudinal mixed methods study of the 10 primary healthcare units (PHCUs) serving ~400,000 people, using monthly indicator tracking and focus groups. SETTING Rural Ethiopia. PARTICIPANTS Ten PHCUs and 140 focus group participants. INTERVENTION The Ethiopian Millennium Rural Initiative. MAIN OUTCOME MEASURES Antenatal care coverage, skilled birth attendant rates, HIV testing in antenatal care, HIV testing in the health center or at health posts overall, outpatient volume at the health center. Qualitative data assessed community members' perceptions of healthcare services. RESULTS We found significant increases (P-values of <0.05) in antenatal care coverage, skilled birth attendant rates, HIV testing in antenatal care and HIV testing at health center and health post levels. Outpatient visit rates also improved, but the change was not significant. Focus group data suggested that communities recognized substantial improvements but also voiced continued unmet needs. CONCLUSIONS A systems-based approach to strengthening rural healthcare units is feasible, although complex, particularly in rural settings. The combined use of quantitative and qualitative data is needed to provide a comprehensive view of impact. Future research is needed to understand the determinants of variation in improvement across health centers and regions.

Abstract
BACKGROUND A large proportion of the 340,000 HIV-positive children in South Africa live in rural areas, yet there is little sub-Saharan data comparing rural paediatric antiretroviral therapy (ART) programme outcomes with urban facilities. We compared clinical, immunological and virological outcomes between children at seven rural and 37 urban facilities across four provinces in South Africa. METHODS We conducted a retrospective cohort study of routine data of children enrolled on ART between November 2003 and March 2008 in three settings, namely: urban residence and facility attendance (urban group); rural residence and facility attendance (rural group); and rural residents attending urban facilities (rural/urban group). Outcome measures were: death, loss to follow up (LTFU), virological suppression, and changes in CD4 percentage and weight-for-age-z (WAZ) scores. Kaplan-Meier estimates, logrank tests, multivariable Cox regression and generalized estimating equation models were used to compare outcomes between groups. RESULTS In total, 2332 ART-naïve children were included, (1727, 228 and 377 children in the urban, rural and rural/urban groups, respectively). At presentation, rural group children were older (6.7 vs. 5.6 and 5.8 years), had lower CD4 cell percentages (10.0% vs. 12.8% and 12.7%), lower WAZ scores (-2.06 vs. -1.46 and -1.41) and higher proportions with severe underweight (26% vs.15% and 15%) compared with the urban and rural/urban groups, respectively. Mortality was significantly higher in the rural group and LTFU significantly increased in the rural/urban group. After 24 months of ART, mortality probabilities were 3.4% (CI: 2.4-4.8%), 7.7% (CI: 4.5-13.0%) and 3.1% (CI: 1.7-5.6%) p = 0.0137; LTFU probabilities were 11.5% (CI: 9.3-14.0%), 8.8% (CI: 4.5-16.9%) and 16.6% (CI: 12.4-22.6%), p = 0.0028 in the urban, rural and rural/urban groups, respectively. The rural group had an increased adjusted mortality probability, adjusted hazards ratio 2.41 (CI: 1.25-4.67) and the rural/urban group had an increased adjusted LTFU probability, aHR 2.85 (CI: 1.41-5.79). The rural/urban group had a decreased adjusted probability of virological suppression compared with the urban group at any timepoint on treatment, adjusted odds ratio 0.67 (CI: 0.48-0.93). CONCLUSIONS Rural HIV-positive children are a vulnerable group, exhibiting delayed access to ART and an increased risk of poor outcomes while on ART. Expansion of rural paediatric ART programmes, with future research exploring improvements to rural health system effectiveness, is required.

Abstract
OBJECTIVE We present early life mortality rates in a largely rural population with high antenatal HIV prevalence, and investigate temporal and spatial associations with a prevention of mother-to-child transmission (PMTCT) programme, an HIV treatment programme, and maternal HIV. DESIGN A retrospective cohort analysis. METHODS All births from January 2000 to January 2007 to women in the Africa Centre demographic surveillance were included. Under-two child mortality rates (U2MR) computed as deaths per 1000 live-births per year; factors associated with mortality risk assessed with Weibull regression. Availability of PMTCT (single-dose nevirapine; sdNVP) and antiretroviral therapy (ART) in a programme included in multivariable analysis. RESULTS Eight hundred and forty-eight (6.2%) of 13 583 children under 2 years died. Deaths in under-twos declined by 49% between 2001 and 2006, from 86.3 to 44.1 deaths per thousand live-births. Mortality was independently associated with birth season (adjusted hazard ratio 1.16, 95% confidence interval 1.02-1.33), maternal education (1.21, 1.02-1.43), maternal HIV (4.34, 3.11-6.04) and ART availability (0.46, 0.33-0.65). Children born at home (unlikely to have received sdNVP) had a 35% higher risk of dying than children born in a facility where sdNVP was available (1.35, 1.04-1.74). For 2005 births the availability of PMTCT and ART in public health programmes would have explained 8 and 31% of the decline in U2MR since 2000. CONCLUSION These findings confirm the importance of maternal survival, and highlight the importance of the PMTCT and especially maternal HIV treatment with direct benefits of improved survival of their young children.
