Physical and sexual abuse in orphaned compared to non-orphaned children in sub-Saharan Africa: A systematic review and meta-analysis

This systematic review assessed the quantitative literature to determine whether orphans are more likely to experience physical and/or sexual abuse compared to non-orphans in sub-Saharan Africa (SSA). It also evaluated the quality of evidence and identified research gaps. Our search identified 10 studies, all published after 2005, from Zimbabwe, South Africa, Kenya and Uganda. The studies consisted of a total 17,336 participants (51% female and 58% non-orphans). Of those classified as orphans (n = 7,315), 73% were single orphans, and 27% were double orphans. The majority of single orphans were paternal orphans (74%). Quality assessment revealed significant variability in the quality of the studies, although most scored higher for general design than dimensions specific to the domain of orphans and abuse. Combined estimates of data suggested that, compared to non-orphans, orphans are not more likely to experience physical abuse (combined OR = 0.96, 95% CI [0.79, 1.16]) or sexual abuse (combined OR = 1.25, 95% CI [0.88, 1.78]). These data suggest that orphans are not systematically at higher risk of experiencing physical or sexual abuse compared to non-orphans in sub-Saharan Africa. However, because of inconsistent quality of data and reporting, these findings should be interpreted with caution. Several recommendations are made for improving data quality and reporting consistency on this important issue

The Perceived Impact of Disclosure of Pediatric HIV Status on Pediatric Antiretroviral Therapy Adherence, Child Well-Being, and Social Relationships in a Resource-Limited Setting

This is a copy of an article published in AIDS Patient Care and STDs © 2010 [copyright Mary Ann Liebert, Inc.]; [AIDS Patient Care and STDs] is available online at: http://online.liebertpub.com.In resource-limited settings, beliefs about disclosing a child’s HIV status and the subsequent impacts of disclosure have not been well studied. We sought to describe how parents and guardians of HIV-infected children view the impact of disclosing a child’s HIV status, particularly for children’s antiretroviral therapy (ART) adherence. A qualitative study was conducted using involving focus groups and interviews with parents and guardians of HIV-infected children receiving ART in western Kenya. Interviews covered multiple aspects of the experience of having children take medicines. Transcribed interview dialogues were coded for analysis. Data were collected from 120 parents and guardians caring for children 0–14 years (mean 6.8 years, standard deviation [SD] 6.4); 118 of 120 had not told the children they had HIV. Children’s caregivers (parents and guardians) described their views on disclosure to children and to others, including how this information-sharing impacted pediatric ART adherence, children’s well-being, and their social relationships. Caregivers believed that disclosure might have benefits such as improved ART adherence, especially for older children, and better engagement of a helping social network. They also feared, however, that disclosure might have both negative psychological effects for children and negative social effects for their families, including discrimination. In western Kenya, caregivers’ views on the risks and benefits to disclosing children’s HIV status emerged a key theme related to a family’s experience with HIV medications, even for families who had not disclosed the child’s status. Assessing caregivers’ views of disclosure is important to understanding and monitoring pediatric ART

Characteristics of HIV-infected children seen in Western Kenya

Objectives: To describe the characteristics and outcomes of children registered for care in a large HIV care programme in Western Kenya. Design: A retrospective descriptive study. Setting: USAID-AMPATH HIV clinics in health centres; district and sub-district hospitals; Moi Teaching and Referral Hospital in Western Kenya. Subjects: HIV-infected children below age of 15 years seen in a network of 18 clinics in Western Kenya. Interventions: Paediatric HIV diagnosis and care including treatment and prevention of opportunistic infections and provision of combination antiretroviral therapy (CART). Main outcome measures: Diagnosis, clinical stage and immune status at enrollment and follow-up; hospitalisation and death. Descriptive statistical analyses and chi square tests were performed. Results: Four thousand and seventeen HIV-infected children seen between June 2002 and April 2008. Median age at enrollment was four years (0-14.2 years), 51% girls, 25% paternal orphans, 10% total orphans and 13% maternal orphans. At enrollment, 25% had weight-for-Age Z scores (WAZ)\u3e -1 and 21% had WAZ scores \u3c 3. Orphaned children had worse WAZ scores (p=0.0001). Twenty five per cent of children were classified as WHO clinical stage 3 and 4, 56% were WHO clinical stages 1 and 2 with 19% missing clinical staging at enrollment. Cough (25%), gastroenteritis (21%), fever (15%), pneumonia (10%) were the commonest presenting features. Twenty six per cent had been diagnosed with tuberculosis and only 25% started on cotrimoxazole preventive therapy (CPT). Median CD4% at enrollment was 16% (0-64%); latest recorded values were 22% (0-64). Sixty four per cent were on cART (cART+), median age at start was 5.4 (014.4 years).The median initial CD4% among cART+ was 13 (0-62) compared to 24 (0-64) for those not on ART (cART-). Median CD4% for cART+ improved to 22% (0-59); whereas cART- was 23% (0- 64) at last appointment. During the period of follow-up, one fifth (19%) of children on cART were lost to follow-up compared to slightly over one third (37%) for those not on cART. Thirty four percent were hospitalised; 41% diagnosed with pneumonia. Six per cent of 4017 were confirmed dead. Conclusions: HIV -infected children were enrolled in care early in childhood. Orphanhood was prevalent in these children as were gastroenteritis, fever, pneumonia and advanced immuno-suppression. Orphans were more likely to be severely malnourished. Only a quarter of children were put on cotrimoxazole preventive therapy. Children commenced on cART late but responded well to treatment. Loss to follow-up was less prevalent among those on cART

Early Childhood Development in Children Born to HIV-Infected Mothers: Perspectives From Kenyan Clinical Providers and Caregivers

Objective. To understand the perspectives of clinical providers and caregivers regarding early childhood development (ECD) in children born to HIV-infected mothers in Kenya. Methods. This was a qualitative study of provider and caregiver perspectives on ECD at 5 Kenyan HIV clinics, using semistructured interviews and focus group discussions. Constant comparison and triangulation methods were employed to elucidate the concepts of ECD. Results. Twenty-five providers and 67 caregivers participated. While providers understood ECD in terms of milestones, caregivers strongly equated ECD with physical growth. Factors affecting ECD, such as nutrition, perinatal effects, and illness, were perceived differently by providers and caregivers. Both groups generally believed that HIV-infected children would have typical ECD if adherent to their HIV treatment. Conclusions. Important considerations regarding ECD in this population were uncovered. Understanding provider and caregiver perspectives’ on ECD in HIV-exposed children is critical for promoting ECD in this community

Growth of young HIV-infected and HIV-exposed children in western Kenya: A retrospective chart review

Introduction The objective of this study was to determine the growth patterns, rates of malnutrition, and factors associated with malnutrition in children born to HIV-infected mothers in western Kenya using data from an electronic medical record system. Methods This study was a retrospective chart review of HIV-infected (HIV+) and–exposed (HEU) children (<5 years) using data collected prospectively in the course of routine clinical care and stored in the electronic medical record system in western Kenya between January 2011 and August 2016. Demographics and anthropometrics were described, with Chi-square testing to compare proportions. Multiple variable logistic regression analysis was used to identify correlates of children being stunted, underweight, and wasted. We also examined growth curves, using a resampling method to compare the areas under the fitted growth curves to compare males/females and HIV+/HEU. Results Data from 15,428 children were analyzed. The children were 51.6% (n = 7,955) female, 5.2% (n = 809) orphans, 83.3% (n = 12,851) were HEU, and 16.7% (n = 2,577) were HIV+. For HIV+ children assessed at 24 months, 50.9% (n = 217) were stunted, 26.5% (n = 145) were underweight, and 13.6% (n = 58) were wasted, while 45.0% (n = 577) of HEU children were stunted, 14.8% (n = 255) were underweight, and 5.1% (n = 65) were wasted. When comparing mean z-scores, HIV+ children tended to have larger and earlier dips in z-scores compared to HIV-exposed children, with significant differences found between the two groups (p<0.001). Factors associated with an increased risk of malnutrition included being male, HIV+, and attending an urban clinic. Maternal antiretroviral treatment during pregnancy and mixed feeding at 3 months of age decreased the risk of malnutrition. Conclusions HIV+ and HEU children differ in their anthropometrics, with HIV+ children having overall lower z-scores. Continued efforts to develop and implement sustainable and effective interventions for malnutrition are needed for children born to HIV+ mothers

Comprehensive evaluation of caregiver-reported antiretroviral therapy adherence for HIV-infected children

For HIV-infected children, adherence to antiretroviral therapy (ART) is often assessed by caregiver report but there are few data on their validity. We conducted prospective evaluations with 191 children ages 0-14 years and their caregivers over 6 months in western Kenya to identify questionnaire items that best predicted adherence to ART. Medication Event Monitoring Systems(®) (MEMS, MWV/AARDEX Ltd., Switzerland) electronic dose monitors were used as external criterion for adherence. We employed a novel variable selection tool using the LASSO technique with logistic regression to identify items best correlated with dichotomized MEMS adherence (≥90 or <90 % doses taken). Nine of 48 adherence items were identified as the best predictors of adherence, including missed or late doses in the past 7 days, problems giving the child medicines, and caregiver-level factors like not being present at medication taking. These items could be included in adherence assessment tools for pediatric patients

Time to First-Line ART Failure and Time to Second-Line ART Switch in the IeDEA Pediatric Cohort

BACKGROUND: Globally, 49% of the estimated 1.8 million children living with HIV are accessing antiretroviral therapy (ART). There are limited data concerning long-term durability of first-line ART regimens and time to transition to second-line. METHODS: Children initiating their first ART regimen between 2 and 14 years of age and enrolled in one of 208 sites in 30 Asia-Pacific and African countries participating in the Pediatric International Epidemiology Databases to Evaluate AIDS consortium were included in this analysis. Outcomes of interest were: first-line ART failure (clinical, immunologic, or virologic), change to second-line, and attrition (death or loss to program ). Cumulative incidence was computed for first-line failure and second-line initiation, with attrition as a competing event. RESULTS: In 27,031 children, median age at ART initiation was 6.7 years. Median baseline CD4% for children ≤5 years of age was 13.2% and CD4 count for those >5 years was 258 cells per microliter. Almost all (94.4%) initiated a nonnucleoside reverse transcriptase inhibitor; 5.3% a protease inhibitor, and 0.3% a triple nucleoside reverse transcriptase inhibitor-based regimen. At 1 year, 7.7% had failed and 14.4% had experienced attrition; by 5 years, the cumulative incidence was 25.9% and 29.4%, respectively. At 1 year after ART failure, 13.7% had transitioned to second-line and 11.2% had experienced attrition; by 5 years, the cumulative incidence was 31.6% and 25.9%, respectively. CONCLUSIONS: High rates of first-line failure and attrition were identified in children within 5 years after ART initiation. Of children meeting failure criteria, only one-third were transitioned to second-line ART within 5 years

Morbidity and mortality in HIV - infected children admitted at Moi Teaching and Referral Hospital in Western Kenya

Background: HIV-infected children are at higher risk of opportunistic infections that could result in hospitalisation. The outcomes of hospitalisation are variable and depend on the admission diagnosis, the patients’ immune status and whether or not the patient is on anti-retroviral drugs.Objective: To describe the characteristics and causes of hospitalisation and mortality for HIV infected children admitted to Moi Teaching and Referral hospital in western Kenya.Design: a retrospective study of prospectively collected data.Setting: The paediatric wards of Moi Teaching and Referral Hospital (MTRH). A Kenyan National Referral Hospital.Subjects: HIV-infected children admitted the paediatric wards.Interventions: Treatment with combination anti-retroviral therapy (cART), treatment of common opportunistic infections.Main outcome measures: Demographic and clinical data, including diagnosis, immune status, and treatment with combination anti-retroviral therapy (cART), were extracted from hospital admission records of HIV-infected children registered with the USAIDAcademic Model Providing Access to Healthcare (AMPATH) partnership. We conducted descriptive statistical analyses and used chi-square and fisher’s exact tests to assess for associations between categorical variables and each of the independent variables.Results: Between December 2006 and May 2009, 396 HIV-infected children were admitted to MTRH. Median age at admission was 2.0 years (range 0-15); 236 (59%) were male; 36 (15%) of available 236 orphan status entries were orphaned; 198 (73%) were in CDC categories B and C and 61 (16%) of available 386 had been on ART. Among 108 patients with documented immunologic status, the mean CD4 cell percentage was 16% (SD 10.8). Among the 396 children, 104 (15%) were diagnosed with pneumonia, 92 (14%) with gastroenteritis, 36 (9%) with tuberculosis and 37 (9%) with malaria. Deaths occurred in 28(7%) of the patients. The median duration of hospitalisation was seven days (range 1- 516) for discharged patients and six days (range 0-72) for those who died. A significantly higher percentage of the children who were not previously enrolled in AMPATH died, signifying 14 (15%) mortality among this population of admitted patients, p = 0.0017. Of those who died, (17%) were diagnosed with pneumonia and 22 (79%) of them were not on cART.Conclusion: The common diagnoses at hospitalisation included pneumonia, gastroenteritis, malaria and tuberculosis. Higher mortality occurred among those diagnosed with pneumonia and those not previously enrolled in the HIV care programme. Aggressive treatment and prevention of the most prevalent diseases and early enrollment into HIV care are recommended for HIV-infected children. A follow-up study to investigate the pathological causes of death in this population is recommended

Adherence to antiretroviral therapy in a clinical cohort of HIV-infected children in East Africa

Objective To describe antiretroviral therapy (ART) adherence and associated factors for a large HIVinfected pediatric cohort followed by sites of the East Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) consortium. Methods This study utilized prospectively collected clinical data from HIV-infected children less than 13 years of age who initiated ART within 4 clinical care programs (with 26 clinical sites) in Kenya, Uganda, and Tanzania and were followed for up to 6 years. Programs used one of 3 adherence measures, including 7-day quantitative recall, 7-day categorical recall, and clinician pill assessments. We fit a hierarchical, three-level, logistic-regression model to examine adherence, with observations nested within patient, and patients within the 26 sites providing pediatric HIV data to this analysis. Results In East Africa, 3,304 children, 52.0% male, were enrolled in care and were subsequently observed for a median of 92 weeks (inter-quartile range [IQR] 50.3±145.0 weeks). Median age at ART initiation was 5.5 years ([IQR] 3.0±8.5 years). ªGoodº adherence, as reported by each clinic\u27s measures, was extremely high, remaining on average above 90% throughout all years of follow-up. Longer time on ART was associated with higher adherence (adjusted Odds Ratio±aOR±per log-transformed week on ART: 1.095, 95% Confidence Interval±CI± [1.052±1.150].) Patients enrolled in higher-volume programs exhibited higher rates of clinician- assessed adherence (aOR per log-500 patients: 1.174, 95% CI [1.108±1.245]).Significant site-level variability in reported adherence was observed (0.28), with even higher variability among patients (0.71). In a sub-analysis, being an orphan at the start of ART was strongly associated with lower ART adherence rates (aOR: 0.919, 95% CI [0.864±0.976]). Conclusions Self-reported adherence remained high over a median of 1.8 years in HIV care, but varied according to patient-level and site-level factors. Consistent adherence monitoring with validated measures and attention to vulnerable groups is recommended
