Burden of HIV among primary school children and feasibility of primary school-linked HIV testing in Harare, Zimbabwe: a mixed methods study

Delivery of index-linked HIV testing for children: learnings from a qualitative process evaluation of the B-GAP study in Zimbabwe

BACKGROUND

Index-linked HIV testing for children, whereby HIV testing is offered to children of individuals living with HIV, has the potential to identify children living with undiagnosed HIV. The "Bridging the Gap in HIV Testing and Care for Children in Zimbabwe" (B-GAP) study implemented and evaluated the provision of index-linked HIV testing for children aged 2-18 years in Zimbabwe. We conducted a process evaluation to understand the considerations for programmatic delivery and scale-up of this strategy.

METHODS

We used implementation documentation to explore experiences of the field teams and project manager who delivered the index-linked testing program, and to describe barriers and facilitators to index-linked testing from their perspectives. Qualitative data were drawn from weekly logs maintained by the field teams, monthly project meeting minutes, the project coordinator's incident reports and WhatsApp group chats between the study team and the coordinator. Data from each of the sources was analysed thematically and synthesised to inform the scale-up of this intervention.

RESULTS

Five main themes were identified related to the implementation of the intervention: (1) there was reduced clinic attendance of potentially eligible indexes due to community-based differentiated HIV care delivery and collection of HIV treatment by proxy individuals; (2) some indexes reported that they did not live in the same household as their children, reflecting the high levels of community mobility; (3) there were also thought to be some instances of 'soft refusal'; (4) further, delivery of HIV testing was limited by difficulties faced by indexes in attending health facilities with their children for clinic-based testing, stigma around community-based testing, and the lack of familiarity of indexes with caregiver provided oral HIV testing; (5) and finally, test kit stockouts and inadequate staffing also constrained delivery of index-linked HIV testing.

CONCLUSIONS

There was attrition along the index-linked HIV testing cascade of children. While challenges remain at all levels of implementation, programmatic adaptations of index-linked HIV testing approaches to suit patterns of clinic attendance and household structures may strengthen implementation of this strategy. Our findings highlight the need to tailor index-linked HIV testing to subpopulations and contexts to maximise its effectiveness.

Storyboarding HIV Infected Young People's Adherence to Antiretroviral Therapy in Lower- to Upper Middle-Income Countries: A New-Materialist Qualitative Evidence Synthesis

Young people living with perinatal infections of Human Immunodeficiency Virus (YLPHIV) face a chronic disease, with treatment including adherence to lifelong antiretroviral treatment (ART). The aim of this QES was to explore adherence to ART for YLPHIV as an assemblage within the framework of the biopsychosocial model with a new materialist perspective. We searched up to November 2021 and followed the ENTREQ and Cochrane guidelines for QES. All screening, data extraction, and critical appraisal were done in duplicate. We analysed and interpreted the findings innovatively by creating images of meaning, a storyboard, and storylines. We then reported the findings in a first-person narrative story. We included 47 studies and identified 9 storylines. We found that treatment adherence has less to do with humans' preferences, motivations, needs, and dispositions and more to do with how bodies, viruses, things, ideas, institutions, environments, social processes, and social structures assemble. This QES highlights that adherence to ART for YLPHIV is a multisensorial experience in a multi-agentic world. Future research into rethinking the linear and casual inferences we are accustomed to in evidence-based health care is needed if we are to adopt multidisciplinary approaches to address pressing issues such as adherence to ART.

Home-based HIV Testing for Children: A Useful Complement for Caregivers with More Children, Who are Male, and with an HIV Negative Partner

Expanding index and family-based testing (HBT) is a priority for identifying children living with HIV. Our study characterizes predictors that drive testing location choice for children of parents living with HIV. Kenyan adults living with HIV were offered a choice of HBT or clinic-based testing (CBT) for any of their children (0-12 years) of unknown HIV status. Multilevel generalized linear models were used to identify correlates of choosing HBT or CBT for children and testing all versus some children within a family, including caregiver demographics, HIV history, social support, cost, and child demographics and HIV prevention history. Among 244 caregivers living with HIV and their children of unknown HIV status, most (72%) caregivers tested children using CBT. In multivariate analysis, female caregivers [aRR 0.52 (95% CI 0.34-0.80)] were less likely to choose HBT than male caregivers. Caregivers with more children requiring testing [aRR 1.23 (95% CI 1.05-1.44)] were more likely to choose HBT than those with fewer children requiring testing. In subgroup univariate analysis, female caregivers with a known HIV negative spouse were significantly more likely to choose HBT over CBT than those with a known HIV positive spouse [RR 2.57 (95% CI 1.28-5.14), p = 0.008], no association was found for male caregivers. Child demographics and clinical history was not associated with study outcomes. Caregiver-specific factors were more influential than child-specific factors in caregiver choice of pediatric HIV testing location. Home-based testing may be preferable to families with higher child care needs and may encourage pediatric HIV testing if offered as an alternative to clinic testing.

Catch them young: Knowledge and awareness levels of HIV and AIDS transmission among high school students in Harare, Zimbabwe

HIV and AIDS has developed as one of the urgent problems affecting many youths in Africa. Yet many of the knowledge and awareness programmes aimed at young people do not target high schools where the majority of young people are found. As a result, many youths do not have accurate information on HIV and AIDS that they can use to protect themselves from the disease. The objectives of this study were to determine the knowledge and awareness of Sixth Form students regarding the spread of HIV and AIDS among young people. A study was carried out among Sixth Form students in three schools in Harare from October 2017 to November 2017. A total of 156 students participated in the survey. Results showed that most students (74%) obtained their information on HIV and AIDS from television and radio programmes. Most students (92%) were able to identify unprotected sexual intercourse as the major mode of HIV transmission, while 89% said that HIV could be transmitted through sharing injections. Some students had misconceptions about HIV and AIDS which might negatively influence their behaviour and attitude towards HIV and AIDS, for example, 11% of students said HIV and AIDS could be cured. The study concludes that programmes on awareness and knowledge application in schools are limited, and efforts should be increased to help students effectively apply the knowledge they have about HIV and AIDS in everyday life situations, and protect themselves from the disease.

School trajectory disruption among adolescents living with perinatal HIV receiving antiretroviral treatments: a case-control study in Thailand

BACKGROUND

Adolescents living with perinatal HIV often experience difficult living circumstances that can impact educational achievement and thus their transition to adult life. We explored their school trajectories and evaluated the contribution of perinatal HIV-infection, in Thailand, where education is free and compulsory until the age of 15.

METHODS

We used data from the Teens Living with Antiretrovirals (TEEWA) study, a cross-sectional case-control study conducted from 2011 to 2014 in Thailand. Participants were 707 adolescents living with perinatal HIV (ALPHIV, cases) aged 12-19 receiving antiretroviral therapy in 19 hospitals throughout Thailand and 689 HIV-uninfected adolescents (controls) living in the same institutions or, for those living in family settings, randomly selected from the general population and individually matched for sex, age, and place of residence. School trajectory disruption was defined as ≥1 year of academic delay or as early school dropout (before 15 years of age). Logistic regression models were used to assess factors independently associated with disrupted school trajectory and to estimate the proportion of school disruption attributable to HIV-infection. We used multivariate imputations by chained equations (MICE) to manage missing data and performed two sensitivity analyses to evaluate the main model's reliability.

RESULTS

The study population's median age was 14.5 years (58% female). School trajectory disruption was experienced by 37% of ALPHIV and 12% of the controls. After adjusting for sociodemographic factors, ALPHIV were 5 times more likely to experience disruption than controls (OR_A =5.2 [3.7-7.2]). About 50% of school trajectory disruption was attributable to HIV-infection. Males and adolescents living in institutions were more likely to experience school trajectory disruption (OR_A =1.8 [1.3-2.4] and OR_A =11.0 [7.7-15.8], respectively). Among ALPHIV, neurocognitive difficulties and growth delay were significantly associated with disruption (OR_A =3.3 [2.1-5.2] and OR_A =1.8 [1.3-2.6], respectively). For those living in families, disruption was also associated with having a caregiver who had less than a secondary-level education (OR_A =2.1 [1.1-3.9]) or having experienced stigmatization (OR_A =1.9 [1.2-3.1]).

CONCLUSIONS

HIV and contextual factors combine to aggravate the educational disadvantage among ALPHIV. The impact of this disadvantage on their life prospects, especially regarding access to higher education and professional achievement, should be further explored.

Unsatisfactory long-term virological suppression in human immunodeficiency virus-infected children in the Amazonas State, Brazil

INTRODUCTION:

Achieving viral suppression (VS) in children is challenging despite the exponential increase in access to antiretroviral therapy (ART). We evaluated VS in children >1 year of age and adolescents 5 years after they had begun ART, in Manaus, Amazonas state, Brazil.

METHODS:

HIV-infected, ART-naive children >1 year of age between 1999 and 2016 were eligible. Analysis was stratified by age at ART initiation: 1-5 y, >5-10 y, and >10-19 y. CD4⁺ T-cell count and viral load were assessed on arrival at the clinic, on ART initiation, and at 6 months, 1 year, 2 years, and 5 years after ART initiation. The primary outcome was a viral load <50 copies/mL 5 years after ART initiation.

RESULTS:

Ultimately, 121 patients were included. The mean age at diagnosis was 4.8 years (SD 3.5), mean CD4% was 17.9 (SD 9.8), and mean viral load was 4.6 log10 copies/ml (SD 0.8). Five years after ART initiation, the overall VS rate was 46.9%. VS by patient age group was as follows: 36.6% for 1-5 y, 53.3% for >5-10 y, and 30% for >10-19 y. Almost all children (90,4%) showed an increase in CD4%+ T cell count. There were no statistically significant predictors for detecting children who do not achieve VS with treatment. VS remained below 65% in all the evaluated periods.

CONCLUSIONS:

Considerable immunological improvement is seen in children after ART initiation. Further efforts are needed to maintain adequate long-term VS levels and improve the survival of this vulnerable population.

They are likely to be there: using a family-centered index testing approach to identify children living with HIV in Kenya

In Kenya, only half of children with a parent living with HIV have been tested for HIV. The effectiveness of family-centered index testing to identify children (0-14 years) living with HIV was examined. A retrospective record review was conducted among adult index patients newly enrolled in HIV care between May and July 2015; family testing, results, and linkage to treatment outcomes were followed through May 2016 at 60 high-volume clinics in Kenya. Chi square test compared yield (percentage of HIV tests positive) among children tested through family-centered index testing, outpatient and inpatient testing. Review of 1937 index client charts led to 3005 eligible children identified for testing. Of 2848 (94.8%) children tested through family-centered index testing, 127 (4.5%) had HIV diagnosed, 100 (78.7%) were linked to care, and 85 of those eligible (91.4%) initiated antiretroviral therapy (ART).Family testing resulted in higher yield compared to inpatient (1.8%, p < 0.001) or outpatient testing (1.6%, p < 0.001). The absolute number of children living with HIV identified was highest with outpatient testing. The relative contribution of testing approach to total children identified with HIV was outpatient testing (69%), family testing (26%), and inpatient testing (5%). The family testing approach demonstrated promise in achieving the first two "90s" (identification and ART initiation) of the 90-90-90 targets for children, with additional effort required to improve linkage from testing to treatment.

Impact of WHO guidelines on trends in HIV testing and ART initiation among children living with HIV in Zambia

BACKGROUND

About 13 years since the introduction of antiretroviral therapy (ART) for children living with HIV (CLHIV) in Zambia, HIV/AIDS testing and treatment guidelines for children have evolved over the years with limited documentation of long-term trends in the numbers testing HIV positive and initiating ART. We examined trends in HIV testing and ART initiation in Zambia.

METHODS

We conducted a retrospective cohort study using routinely collected patient level data from 496 health facilities across Zambia. We used Poisson regression to derive incident rate ratios and 95% confidence intervals (95% CI) for background characteristics and used a Cuzick non-parametric test for trends to test the 13-year trends. Median time from testing to ART initiation in days and incidence rates were derived using life tables in survival analysis. We used multi-level random effects Poisson regression model to determine variations in time from HIV testing to ART initiation by facility.

RESULTS

Overall, the cumulative proportion of the children who tested positive and initiated antiretroviral therapy (ART for HIV) from 2004 to 2017 was 69% (n = 99 592). During the period under review proportions of ART initiation increased from 52% in 2004-2006 to 97% in 2016-2017 (P < 0.001) and time from testing to ART initiation reduced from a median of 17 days IQR (1-161) in 2004 to one day IQR (1-14), P < 0.001 in 2016-2017. CLHIV were 15 times more likely to be initiated on ART in 2016-17 compared to period 2004-6 (IRR = 15.2, 95% CI 14.7-15.7). Time to ART initiation increased with age and was higher in rural health facilities compared to urban facilities. About 11% of the variability in time to ART initiation in children could be attributed to differences between facilities.

CONCLUSIONS

The substantial increase in ART initiation and reduction in time to ART initiation among CLHIV identified in this study, reflects improvements in the paediatric HIV programme in Zambia in relation to health care delivery and adherence to national testing and treatment guidelines that were adapted from WHO guidelines. However, age-related differentials in rates of ART initiation suggests that urgent interventions are needed to sustain and further improve programme performance.

Family Testing: An Index Case Finding Strategy to Close the Gaps in Pediatric HIV Diagnosis

Despite significant advances in pediatric HIV treatment, too many children remain undiagnosed and thus without access to lifesaving antiretroviral therapy. It is critical to identify these children and initiate antiretroviral therapy as early as possible. Although the children of HIV-infected adults are at higher risk of infection, few access HIV testing services because of missed opportunities in existing case finding programs. Family testing is an index case finding strategy through which HIV-infected patients are systematically screened to identify family members with unknown HIV status. By specifically targeting a high-risk population, family testing is a pragmatic, high-yield, and efficient approach to identify previously undiagnosed HIV-infected children and link them to care before they become symptomatic. Despite this, incorporation of family testing into national guidelines and implementation of this case finding approach is variable. In this article, we review the evidence base for family testing, describe its challenges, and provide guidance and sample tools for program managers aiming to integrate family testing into existing health systems.

Educational delays among children living with perinatally-acquired HIV in Johannesburg, South Africa

Little is known about how growing up with HIV impacts educational outcomes in sub-Saharan African children. We evaluated if South African children living with HIV (CLWH) were in the appropriate school grade-for-age compared to uninfected control children. We observed higher rates of not being in the correct grade-for-age in CLWH compared with controls (OR 3.32, 95% CI: 2.07-5.34), adjusted for study site, sex, whether the child's biological father was alive, and caregiver education. Initiation of ART before 6 months of age reduced but did not eliminate this association. Whether these associations are due to biological factors or other social and environmental determinants, and how best to support CLWH to achieve educational goals, warrants further investigation.

Health worker text messaging for blended learning, peer support, and mentoring in pediatric and adolescent HIV/AIDS care: a case study in Zimbabwe

BACKGROUND

In sub-Saharan Africa, shortages of trained healthcare workers and limited resources necessitate innovative and cost-effective approaches for training, supervising, and mentoring. This qualitative case study describes participants' and trainers' perspectives and experiences with a text messaging component of a blended training course in HIV counseling and testing in Zimbabwe, using minimal resources in terms of staff time and equipment requirements. This component included a whole-group discussion forum as well as two-person partner discussions designed to promote reflection and analysis, teamwork, and active learning.

CASE PRESENTATION

The Ministry of Health and Child Care (MoHCC) of Zimbabwe collaborated with the International Training and Education Center for Health (I-TECH) on adaptation of a 5-day in-service training in HIV Testing Services for Children and Adolescents. The new 7-week blended format included in-person sessions, tablet-based self-study, and discussions using the text messaging application, WhatsApp. Between August 2016 and January 2017, 11 cohorts (293 participants in total) were trained with this new curriculum, incorporating text messaging to support peer-to-peer and work-based education. Data collected included training participants' feedback, key informant interviews with the training team, and thematic analysis of WhatsApp messages from full-cohort discussions and a sampling of one-to-one partner discussions. A total of 293 healthcare workers from 233 health facilities across all provinces in Zimbabwe completed the blended learning course. Participants strongly endorsed using WhatsApp groups as part of the training. In the whole-group discussions, the combined cohorts generated over 6300 text messages. Several categories of communication emerged in analysis of group discussions: (1) participants' case experiences and questions; (2) feedback and recommendations for work issues raised; (3) inquiries, comments, and responses about course assignments and specific course content; (4) encouragement; and (5) technical challenges encountered using the blended learning methodology. Case discussions were complex, including patient history, symptoms, medications, and psychosocial issues-child abuse, adherence, and disclosure.

CONCLUSIONS

Using text messaging in a communication platform that is an ongoing part of healthcare workers' daily lives can be an effective adjunct to in-service training, minimizing isolation and providing interactivity, supporting students' ability to fully integrate content into new skill attainment.

Barriers to, and emerging strategies for, HIV testing among adolescents in sub-Saharan Africa

PURPOSE OF REVIEW

HIV/AIDS is one of the leading causes of death among adolescents in sub-Saharan Africa and 40% of new HIV infections worldwide occur in this group. HIV testing and counselling (HTC) is the critical first step to accessing HIV treatment. The prevalence of undiagnosed HIV infection is substantially higher in adolescents compared with adults. We review barriers to HTC for adolescents and emerging HTC strategies appropriate to adolescents in sub-Saharan Africa.

RECENT FINDINGS

There are substantial individual, health system and legal barriers to HTC among adolescents, and stigma by providers and communities remains an important obstacle. There has been progress made in recent years in developing strategies that address some of these barriers, increase uptake of HTC and yield of HIV. These include targeted approaches focused on provision of HTC among those higher risk of being infected, for example, index-linked HTC and use of screening tools to identify those at risk of HIV. Community-based HIV-testing approaches including HIV self-testing and incentives have also been shown to increase uptake of HTC.

SUMMARY

In implementing HTC strategies, consideration must be given to scalability and cost-effectiveness. HTC approaches must be coupled with linkage to appropriate care and prevention services.

Brief Report: Disclosure, Consent, Opportunity Costs, and Inaccurate Risk Assessment Deter Pediatric HIV Testing: A Mixed-Methods Study

BACKGROUND

Prompt child HIV testing and treatment is critical; however, children are often not diagnosed until symptomatic. Understanding factors that influence pediatric HIV testing can inform strategies to increase testing.

METHODS

A mixed-methods study was conducted at a tertiary hospital in Nairobi, Kenya. Three focus group discussions with health care workers (HCWs) and 18 in-depth interviews with HIV-infected adults with children of unknown status were analyzed using thematic analysis. A structured questionnaire was administered to 116 HIV-infected caregivers of children of unknown status to triangulate qualitative findings.

RESULTS

Analysis revealed 3 key periods of the pediatric HIV testing process: decision to test, test visit, and posttest. Key issues included: decision to test: inaccurate HIV risk perception for children, challenges with paternal consent, lack of caregiver HIV status disclosure to partners or older children; test experience: poor understanding of child consent/assent and disclosure guidelines, perceived costs of testing and care, school schedules, HCW discomfort with pediatric HIV testing; and posttest: pessimism regarding HIV-infected children's prognosis, caregiver concerns about their own emotional health if their child is positive, and challenges communicating about HIV with children. Concerns about all 3 periods influenced child testing decisions. In addition, 3 challenges were unique to pediatric HIV: inaccurate HIV risk perception for children; disclosure, consent, and permission; and costs and scheduling.

CONCLUSIONS

Pediatric HIV testing barriers are distinct from adult barriers. Uptake of pediatric HIV testing may be enhanced by interventions to address misconceptions, disclosure services, psychosocial support addressing concerns unique to pediatric testing, child-focused HCW training, and alternative clinic hours.

Traversing the cascade: urgent research priorities for implementing the 'treat all' strategy for children and adolescents living with HIV in sub-Saharan Africa

Children and adolescents living with HIV (CALHIV) in sub-Saharan Africa experience significant morbidity and alarmingly high mortality rates due to critical gaps in the HIV care cascade, including late diagnosis and initiation of treatment, as well as poor retention in care and adherence to treatment. Interventions to strengthen the adult HIV care cascade may not be as effective in improving the cascade for CALHIV, for whom specific strategies are needed. Particular attention needs to be paid to the contexts of sub-Saharan Africa, where more than 85% of the world's CALHIV live. Implementing the 'treat all' strategy in sub-Saharan Africa requires dedicated efforts to address the unique diagnosis and care needs of CALHIV, in order to improve paediatric and adolescent outcomes, prevent viral resistance and reduce the number of new HIV infections. We consider the UNAIDS 90-90-90 targets from the perspective of infants, children and adolescents, and discuss the key challenges, knowledge gaps and urgent research priorities for CALHIV in implementation of the 'treat all' strategy in sub-Saharan Africa.

Screening tool to identify adolescents living with HIV in a community setting in Zimbabwe: A validation study

INTRODUCTION

A simple cost-effective strategy to pre-screen for targeted HIV testing can have substantial benefit in high burden and resource limited settings. A 4-item (previous hospitalisation, orphanhood, poor health status, and recurring skin problems) screening tool to identify adolescents living with HIV has previously shown high sensitivity in healthcare facility settings. We validated this screening tool in a community setting, in Harare, Zimbabwe in a community-based HIV prevalence survey.

METHODS

A community-based HIV prevalence survey was conducted among individuals aged 8-17 years with guardian consent and child assent and residing in 7 communities during the period February 2015 to December 2015. Participants without previously diagnosed HIV were evaluated for the probability of having HIV using the screening tool. HIV status was defined using an anonymous HIV test which was done using Oral Mucosal Transudate (OMT). A questionnaire was also administered to ascertain self-reported HIV status and screening tool items. The validity of a 4-item screening tool was tested. Sensitivity and specificity of the screening tool was assessed against the HIV status based on OMT result.

RESULTS

Prevalence survey participants were 5386 children who had an HIV test result, aged 8-17 years. However, 5384, who did not report testing HIV positive and responded to all screening tool item questions were included in the validation. Their median age was 12 (IQR: 10-15) years, 2515 (46.7%) were male. HIV prevalence was 1.3% (95% CI:1.0-1.8%). The 4-item screening tool had poor accuracy with an area under the receiver operating curve of 0.65(95% CI: 0.60-0.72) at a cut-off score≥1. Its sensitivity was 56.3% (95% CI:44.0-68.1%) and specificity of 75.1% (95% CI:73.9-76.3%), PPV of 2.9% (95% CI:2.1-3.9%) and a NPV of 99.2% (95% CI:98.9-99.5%). The number needed to test to diagnose one child using the screening tool was 55% lower than universal testing for HIV.

CONCLUSION

Use of the 4-item screening tool could be a strategy that can be adopted to identify children living with HIV in a community setting in resource limited settings by reducing the number needed to test compared to universal testing since it is inexpensive, easy to administer and not harmful. However, screening items adapted to a community setting need to be explored to improve the performance of the screening tool.

Strategies for Identifying and Linking HIV-Infected Infants, Children, and Adolescents to HIV Treatment Services in Resource Limited Settings

Many children living with HIV in resource-limited settings remain undiagnosed and at risk for HIV-related mortality and morbidity. This article describes 5 key strategies for strengthening HIV case finding and linkage to treatment for infants, children, and adolescents. These strategies result from lessons learned during the Accelerating Children's HIV/AIDS Treatment Initiative, a public-private partnership between the President's Emergency Plan for AIDS Relief (PEPFAR) and the Children's Investment Fund Foundation (CIFF). The 5 strategies include (1) implementing a targeted mix of HIV case finding approaches (eg, provider-initiated testing and counseling within health facilities, optimization of early infant diagnosis, index family testing, and integration of HIV testing within key population and orphan and vulnerable children programs); (2) addressing the unique needs of adolescents; (3) collecting and using data for program improvement; (4) fostering a supportive political and community environment; and (5) investing in health system-strengthening activities. Continued advocacy and global investments are required to eliminate AIDS-related deaths among children and adolescents.

Acceptability and performance of a directly assisted oral HIV self-testing intervention in adolescents in rural Mozambique

INTRODUCTION

Whereas progress in HIV testing and treatment has been made globally, the UNAIDS goal of "90 90 90" is still out of sight in rural northern Mozambique. New strategies that promote testing in hard to reach groups will aid Mozambique's response to the HIV epidemic. HIV self-testing (HIVST) is recommended by the WHO as an additional approach to augment the HIV testing services available to adolescents. This study evaluates acceptability and performance of a directly assisted oral HIVST intervention for adolescents in rural Mozambique.

METHODS

Adolescents aged 16-20 years were included at schools and invited to attend the local hospital's youth friendly service for directly assisted oral HIVST. Baseline and post-test questionnaires were obtained. OraQuick Rapid HIV-1/2 Anti body test® was used. Results were read by the participant and by a nurse. Results were confirmed by finger prick HIV test (Determine® HIV 1/2 Alere and Unigold™ HIV Trinity Biotech) according to the Mozambican national standard.

RESULTS

Between September and November 2016, 496 adolescents were included, of which 299 performed an oral HIV self-test. 70% were first time testers. The positivity rate was 1.7%. The inter-rater agreement between adolescent and nurse was 99.6% (kappa 0.93); there were no false negative or false positive results of the oral HIV self-test. Five tests were invalid. 7.1% found the test difficult to use. Over 80% preferred directly assisted HIVST compared to the standard finger prick testing. While 20% thought it would be good to do HIVST at home, 76% preferred to do HIVST at the health centre, for reasons including increased security, privacy, and the presence of a counsellor.

CONCLUSIONS

Directly assisted oral HIVST is a feasible intervention for adolescents in rural Mozambique and showed encouraging results for first time HIV testers.

Scaling up Pediatric HIV Testing by Incorporating Provider-Initiated HIV Testing Into all Child Health Services in Hurungwe District, Zimbabwe

BACKGROUND

Practical ways are needed to scale-up pediatric HIV testing in sub-Saharan Africa, where testing is usually limited to HIV-exposed children in maternal and child health clinics.

METHODS

We implemented an enhanced pediatric HIV testing program in 33 health facilities in Zimbabwe by integrating HIV testing into all pediatric health services. We collected individual data on children tested by having health care workers complete a program-specific child health booklet. We compared numbers of children tested before and during the program using routinely collected aggregate program data reported by health facilities.

RESULTS

A total of 12,556 children aged 0-5 years were recorded in child health booklets; 9431 (75.1%) had information on HIV testing, of whom 7326 (77.7%) were tested; 7167 had test results of whom 122 (1.7%) were HIV-infected. Among children seen in outpatient clinics, 82.1% were tested compared with 66.5% tested among children seen in maternal/child health clinics. Of the 122 HIV-infected children identified, 77 (63.1%) could be missed under existing pediatric testing guidelines. The number of HIV-infected children identified during the 6-month program increased by 55% compared with the prior 6-month period (RR = 1.55, 95% CI: 1.22 to 1.96). Factors independently associated with HIV infection included being malnourished (adjusted odds ratio [AOR] = 7.7, 95% CI: 2.1 to 28.6), being exposed to TB (AOR = 8.1, 95% CI: 2.0 to 32.2), and having an HIV-infected mother (AOR = 41.6, 95% CI: 15.9 to 108.8).

CONCLUSIONS

Integrating HIV testing into all pediatric health services is feasible and can assist in identifying HIV-infected children who could be missed in current testing guidelines.

[Seroprevalence and factors associated with Voluntary Counselling and Testing (VCT) for HIV among children in Lubumbashi, Democratic Republic of the Congo]

Introduction

Malgré le dépistage du VIH proposé lors de la naissance ou au cours des consultations préscolaires, la proportion des enfants qui croissent ou décèdent sous statut sérologique au VIH inconnu est importante en République Démocratique du Congo (RDC). L’objectif de cette étude était de déterminer la séroprévalence au cours d’un dépistage volontaire et d’identifier les facteurs associés à l’acceptation du conseil et dépistage du VIH (CDV) en dehors de la maladie ou de toute exposition au VIH dans une population pédiatrique à Lubumbashi, RDC.

Méthodes

Il s’agissait d’une étude prospective transversale à visée analytique menée du 1^er août 2006 au 31 septembre 2007. Elle avait été réalisée dans 4 centres communautaires de CDV répartis dans 4 zones de santé de la ville de Lubumbashi en RDC (Lubumbashi, Ruashi, Kampemba et de Kenya). L’étude avait consisté à faire le dépistage volontaire du VIH chez les enfants de moins de 15 ans. Les caractéristiques sociodémographiques et les paramètres relatifs au conseil et dépistage volontaire ont été étudiés. Les analyses statistiques descriptives usuelles et une régression logistique ont été réalisées.

Résultats

Sur 463 enfants dépistés du VIH, 41 (8,9%; IC 95%: 6,5%-11,9%) ont été testés positifs. L’acceptation du conseil et dépistage volontaire du VIH en dehors de la maladie ou de l’exposition au VIH était significativement plus élevée lorsque l’enfant était âgé de plus de 2 ans (Odds ratio ajusté (ORa) = 3,6 [IC 95%: 1,1-12,2]), lorsque le statut sérologique du VIH des parents était négatif ou inconnu (ORa = 27,4 [IC 95%: 9,4-80,0]), lorsque l’un ou l’autre ou les deux parents biologiques étaient en vie (ORa = 24,9 [IC 95%: 2,4-250,8]) et lorsque la connaissance du lieu de dépistage était fait par des moyens autres que le professionnel de santé (ORa = 2,9 [IC 95%: 1,0-7,9]).

Conclusion

Notre étude montre une forte prévalence du VIH chez les enfants justifiant la nécessité de réaliser le CDV qui est significativement accepté par leurs parents et tuteurs dans la ville de Lubumbashi.

Why Tell Children: A Synthesis of the Global Literature on Reasons for Disclosing or Not Disclosing an HIV Diagnosis to Children 12 and under

While the psychological and health benefits of knowing one's HIV diagnosis have been documented for adults and adolescents, practice is still in development for younger children. Moderating conditions for whether or not to tell a child he/she has HIV vary by region and local context. They include accessibility of treatment, consideration of HIV as a stigmatizing condition, prevalence of HIV, and an accompanying presumption that any illness is HIV-related, parent or caregiver concerns about child reactions, child's worsening health, assumptions about childhood and child readiness to know a diagnosis, and lack of policies such as those that would prevent bullying of affected children in schools. In this systematic review of the global literature, we summarize the reasons caregivers give for telling or not telling children 12 and under their HIV diagnosis. We also include articles in which children reflect on their desires for being told. While a broad number of reasons are given for telling a child - e.g., to aid in prevention, adaptation to illness (e.g., primarily to promote treatment adherence), understanding social reactions, and maintaining the child-adult relationship - a narrower range of reasons, often related to immediate child or caregiver well-being or discomfort, are given for not telling. Recommendations are made to improve the context for disclosure by providing supports before, during, and after disclosure and to advance the research agenda by broadening samples and refining approaches.

Community-Based HIV and Health Testing for High-Risk Adolescents and Youth

Adolescents account for 40% of new HIV infections, and HIV testing strategies to increase uptake of testing are needed. A community-based adolescent and youth HIV and health testing campaign was conducted in seven slum neighborhoods of Port-au-Prince, Haiti, from December 2014 to September 2015. Community health workers provided community sensitization and recruited 10- to 24-year-olds to test for HIV, syphilis, gonorrhea/chlamydia, and to screen for tuberculosis (TB) and pregnancy. HIV-infected individuals were escorted to the GHESKIO HIV clinic for same-day enrollment in care. Among 3425 individuals eligible for testing, 3348 (98%) accepted an HIV test. HIV prevalence was 2.65% (n = 89). Median age was 19 [interquartile range (IQR) 17-20]; 73% were female. HIV prevalence was 0.6-7.4% across slum neighborhoods. All HIV-infected individuals enrolled in care the same day as testing; median CD4 was 529 cells/μL [IQR 363-761]. Syphilis prevalence was 2.60% (65/2536) and gonorrhea/chlamydia prevalence was 6.25% (96/1536). Among 168 (5%) individuals who reported TB symptoms, 7.7% (13/168) had microbiologically confirmed disease. One hundred twenty-nine females (5% of all females) were pregnant. This community-based testing campaign identified an adolescent and youth population with an HIV prevalence six times higher than the estimated national adolescent HIV prevalence (0.4%) in Haiti, including perinatally infected adolescents. This type of community-based campaign for HIV testing within a package of services can serve as a model for other resource-poor settings to identify high-risk adolescents and youth, and curb the global HIV epidemic among adolescents.

Acceptance of provider-initiated testing and counseling for HIV infection by caregivers in a tertiary health institution in Abuja, Nigeria: a cross sectional study

INTRODUCTION

Less than 10% of HIV positive children are enrolled into antiretroviral treatment program in the country. Provider-initiated testing and counseling was introduced to increasing uptake of HIV testing. The aim of this study is to determine the acceptability and factors undermining the acceptance of this laudable initiative by parents/caregivers of children attending paediatric out patient clinical services in our health institution.

METHODS

A cross sectional study of children aged 18 months to 18 years and their parents/caregivers attending paediatric outpatient clinic of the hospital was undertaken for the above objectives.

RESULTS

There were statistically more female parents/caregivers (82.5%, p=0.00), more male patients (52.9 %, p= 0.02), and 11.9% adolescents in this study. While 91.7% of parents/caregivers admitted not having knowledge of provider-initiated testing and counseling, 95.6% knew what HIV was. Acceptance of the program was high (98.7%), majority (89.7%) wanting to know the HIV status of their children/wards. Non-acceptance was small (1.2%), there main reason being prior knowledge of their HIV status. Prevalence of HIV among tested children was 1.7%. There was a strong relationship between having willingness to test for HIV and many of the study variables with religion of the parents/caregivers having the strongest relationship [OR: 13.94, (CI 1.82, 55.34)], and tribe having list association, [OR: 3.60, (CI 1.85, 17.14)].

CONCLUSION

There was general wiliness to accept HIV test for children by their parents/caregiver in this study, and HIV prevalence in children is on a downward trend; its sustenance to be continued and adolescent clinics need to be created.

Uptake and yield of HIV testing and counselling among children and adolescents in sub-Saharan Africa: a systematic review

INTRODUCTION

In recent years children and adolescents have emerged as a priority for HIV prevention and care services. We conducted a systematic review to investigate the acceptability, yield and prevalence of HIV testing and counselling (HTC) strategies in children and adolescents (5 to 19 years) in sub-Saharan Africa.

METHODS

An electronic search was conducted in MEDLINE, EMBASE, Global Health and conference abstract databases. Studies reporting on HTC acceptability, yield and prevalence and published between January 2004 and September 2014 were included. Pooled proportions for these three outcomes were estimated using a random effects model. A quality assessment was conducted on included studies.

RESULTS AND DISCUSSION

A total of 16,380 potential citations were identified, of which 21 studies (23 entries) were included. Most studies were conducted in Kenya (n=5) and Uganda (n=5) and judged to provide moderate (n=15) to low quality (n=7) evidence, with data not disaggregated by age. Seven studies reported on provider-initiated testing and counselling (PITC), with the remainder reporting on family-centred (n=5), home-based (n=5), outreach (n=5) and school-linked HTC among primary schoolchildren (n=1). PITC among inpatients had the highest acceptability (86.3%; 95% confidence interval [CI]: 65.5 to 100%), yield (12.2%; 95% CI: 6.1 to 18.3%) and prevalence (15.4%; 95% CI: 5.0 to 25.7%). Family-centred HTC had lower acceptance compared to home-based HTC (51.7%; 95% CI: 10.4 to 92.9% vs. 84.9%; 95% CI: 74.4 to 95.4%) yet higher prevalence (8.4%; 95% CI: 3.4 to 13.5% vs. 3.0%; 95% CI: 1.0 to 4.9%). School-linked HTC showed poor acceptance and low prevalence.

CONCLUSIONS

While PITC may have high test acceptability priority should be given to evaluating strategies beyond healthcare settings (e.g. home-based HTC among families) to identify individuals earlier in their disease progression. Data on linkage to care and cost-effectiveness of HTC strategies are needed to strengthen policies.

The burden of disease on HIV-infected orphaned and non-orphaned children accessing primary health facilities in a rural district with poor resources in South Africa: a cross-sectional survey of primary caregivers of HIV-infected children aged 5-18 years

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.

HIV in children in a general population sample in East Zimbabwe: prevalence, causes and effects

Background

There are an estimated half-million children living with HIV in sub-Saharan Africa. The predominant source of infection is presumed to be perinatal mother-to-child transmission, but general population data about paediatric HIV are sparse. We characterise the epidemiology of HIV in children in sub-Saharan Africa by describing the prevalence, possible source of infection, and effects of paediatric HIV in a southern African population.

Methods

From 2009 to 2011, we conducted a household-based survey of 3389 children (aged 2–14 years) in Manicaland, eastern Zimbabwe (response rate: 73.5%). Data about socio-demographic correlates of HIV, risk factors for infection, and effects on child health were analysed using multi-variable logistic regression. To assess the plausibility of mother-to-child transmission, child HIV infection was linked to maternal survival and HIV status using data from a 12-year adult HIV cohort.

Results

HIV prevalence was (2.2%, 95% CI: 1.6–2.8%) and did not differ significantly by sex, socio-economic status, location, religion, or child age. Infected children were more likely to be underweight (19.6% versus 10.0%, p = 0.03) or stunted (39.1% versus 30.6%, p = 0.04) but did not report poorer physical or psychological ill-health. Where maternal data were available, reported mothers of 61/62 HIV-positive children were deceased or HIV-positive. Risk factors for other sources of infection were not associated with child HIV infection, including blood transfusion, vaccinations, caring for a sick relative, and sexual abuse. The observed flat age-pattern of HIV prevalence was consistent with UNAIDS estimates which assumes perinatal mother-to-child transmission, although modelled prevalence was higher than observed prevalence. Only 19/73 HIV-positive children (26.0%) were diagnosed, but, of these, 17 were on antiretroviral therapy.

Conclusions

Childhood HIV infection likely arises predominantly from mother-to-child transmission and is associated with poorer physical development. Overall antiretroviral therapy uptake was low, with the primary barrier to treatment appearing to be lack of diagnosis.

Barriers to provider-initiated testing and counselling for children in a high HIV prevalence setting: a mixed methods study

BACKGROUND

There is a substantial burden of HIV infection among older children in sub-Saharan Africa, the majority of whom are diagnosed after presentation with advanced disease. We investigated the provision and uptake of provider-initiated HIV testing and counselling (PITC) among children in primary health care facilities, and explored health care worker (HCW) perspectives on providing HIV testing to children.

METHODS AND FINDINGS

Children aged 6 to 15 y attending six primary care clinics in Harare, Zimbabwe, were offered PITC, with guardian consent and child assent. The reasons why testing did not occur in eligible children were recorded, and factors associated with HCWs offering and children/guardians refusing HIV testing were investigated using multivariable logistic regression. Semi-structured interviews were conducted with clinic nurses and counsellors to explore these factors. Among 2,831 eligible children, 2,151 (76%) were offered PITC, of whom 1,534 (54.2%) consented to HIV testing. The main reasons HCWs gave for not offering PITC were the perceived unsuitability of the accompanying guardian to provide consent for HIV testing on behalf of the child and lack of availability of staff or HIV testing kits. Children who were asymptomatic, older, or attending with a male or a younger guardian had significantly lower odds of being offered HIV testing. Male guardians were less likely to consent to their child being tested. 82 (5.3%) children tested HIV-positive, with 95% linking to care. Of the 940 guardians who tested with the child, 186 (19.8%) were HIV-positive.

CONCLUSIONS

The HIV prevalence among children tested was high, highlighting the need for PITC. For PITC to be successfully implemented, clear legislation about consent and guardianship needs to be developed, and structural issues addressed. HCWs require training on counselling children and guardians, particularly male guardians, who are less likely to engage with health care services. Increased awareness of the risk of HIV infection in asymptomatic older children is needed.

The impact of HIV on children's education in eastern Zimbabwe

Little is known about how HIV impacts directly and indirectly on receiving, or particularly succeeding in, education in sub-Saharan Africa. To address this gap, we used multivariable logistic regression to determine the correlation between education outcomes in youth (aged 15–24) (being in the correct grade-for-age, primary school completion and having at least five “O” level passes) and being HIV-positive; having an HIV-positive parent; being a young carer; or being a maternal, paternal or double orphan, in five rounds (1998–2011) of a general population survey from eastern Zimbabwe. The fifth survey round (2009–2011) included data on children aged 6–17, which were analysed for the impacts of the above risk factors on regular attendance in primary and secondary schools and being in the correct grade-for-age. For data pooled over all rounds, being HIV-positive had no association with primary school completion, “O” level passes, or being in the correct grade-for-age in adolescents aged 16–17 years. Additionally, HIV status had no significant association with any education outcomes in children aged 6–17 surveyed in 2009–2011. In 2009–2011, being a young carer was associated with lower attendance in secondary school (69% vs. 85%, AOR: 0.44; p = 0.02), whilst being a maternal (75% vs. 83%, AOR: 0.67; p < 0.01), paternal (76% vs. 83%, AOR: 0.67; p = 0.02) or double (75% vs. 83%, AOR: 0.68; p = 0.02) orphan was associated with decreased odds of being in the correct grade-for-age. All forms of orphanhood also significantly decreased the odds of primary school completion in youths surveyed from 1998 to 2011 (all p < 0.01). We found no evidence that HIV status affects education but further evidence that orphans do experience worse education outcomes than other children. Combination approaches that provide incentives for children to attend school and equip schools with tools to support vulnerable children may be most effective in improving education outcomes and should be developed and evaluated.

Beyond early infant diagnosis: case finding strategies for identification of HIV-infected infants and children

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

Enhancing psychosocial support for HIV positive adolescents in Harare, Zimbabwe

Background

There is a recognized gap in the evidence base relating to the nature and components of interventions to address the psycho-social needs of HIV positive young people. We used mixed methods research to strengthen a community support group intervention for HIV positive young people based in Harare, Zimbabwe.

Methods

A quantitative questionnaire was administered to HIV positive Africaid support group attendees. Afterwards, qualitative data were collected from young people aged 15–18 through tape-recorded in-depth interviews (n = 10), 3 focus group discussions (FGDs) and 16 life history narratives. Data were also collected from caregivers, health care workers, and community members through FGDs (n = 6 groups) and in-depth interviews (n = 12). Quantitative data were processed and analysed using STATA 10. Qualitative data were analysed using thematic analysis.

Results

229/310 young people completed the quantitative questionnaire (74% participation). Median age was 14 (range 6–18 years); 59% were female. Self-reported adherence to antiretrovirals was sub-optimal. Psychological well being was poor (median score on Shona Symptom Questionnaire 9/14); 63% were at risk of depression. Qualitative findings suggested that challenges faced by positive children include verbal abuse, stigma, and discrimination. While data showed that support group attendance is helpful, young people stressed that life outside the confines of the group was more challenging. Caregivers felt ill-equipped to support the children in their care. These data, combined with a previously validated conceptual framework for family-centred interventions, were used to guide the development of the existing programme of adolescent support groups into a more comprehensive evidence-based psychosocial support programme encompassing caregiver and household members.

Conclusions

This study allowed us to describe the lived experiences of HIV positive young people and their caregivers in Zimbabwe. The findings contributed to the enhancement of Africaid’s existing programme of support to better promote psychological well being and ART adherence.
