A Single Question on Maternal HIV Status Can Improve Identification of Children Living With HIV in South Africa

INTRODUCTION

Screening tools to improve identification of children living with HIV (CLHIV) have been validated and used in various settings. The aim of our study was to optimize a screening tool for Primary Healthcare Clinics (PHCs) in South Africa (SA).

METHODS

A cross-sectional study was conducted at PHCs in Johannesburg and Mopani Districts, between June 2021 and June 2022. Children 5-14 years of age with HIV negative or unknown status accompanied by their mothers, or appropriate caregivers, were enrolled. Demographic data, responses to the screening tool questions, and HIV test results were captured. Logistic regression modeling was used to optimize an existing 10-item screening tool, and sensitivity, specificity, and number needed to test (NNT) used to choose the final tool.

RESULTS

We enrolled 14,147 children in the study, with 62 children testing HIV positive (HIV positivity of 0.4%). The 10-item tool with a single positive response had a sensitivity of 91.9% and specificity of 43.3%. An optimal combination of 5-items with two positive responses had the lowest NNT of 72, 82.3% sensitivity and 74.2% specificity. Maternal HIV status alone, HIV positive or unknown, had a 95.2% sensitivity, 65.0% specificity and NNT of 84. The 1-item tool only would have missed 5% of CLHIV (N = 3) compared with the 5-item tool that missed 18% (n = 11).

CONCLUSIONS

A 1-item screening tool asking about maternal HIV status can improve efficiency of testing of children in primary healthcare facilities in SA and improve identification of CLHIV who are not on treatment.

Risk profile of postnatal women and their babies attending a rural district hospital in South Africa

Background

Maternal and neonatal mortality remain unacceptably high and inequitably distributed in South Africa, with the postnatal period being a dangerous time for both mother and baby. The aim of this paper is to describe the risk factors for poor postnatal outcomes, including postnatal mental health disorders, in a population of postnatal women and their babies utilising rural district hospital services in Limpopo Province, with a focus on HIV. We also describe health care provider compliance with relevant guidelines.

Methods

All women discharged from the postnatal ward of the district hospital who consented to participate were enrolled. A research nurse used a structured questionnaire to collect data about sociodemographic information, pregnancy and pre-existing conditions, complications during labour and birth, pregnancy outcomes and mental health risk factors.

Results

The questionnaire was completed for 882 women at the time of discharge. Only 354 (40.2%) of participants had completed secondary education, and 105 (11.9%) reported formal employment. Chronic hypertension was recorded in 20 women (2.3%), with an additional 49 (5.6%) developing a hypertensive disorder during pregnancy. HIV prevalence was 22.8%. 216 women (24.5%) had a mental health risk factor, with 40 reporting more than one (4.5%). Having no income, no antenatal care, having HIV and any hypertensive disorder were significantly associated with a positive mental health risk screen in multivariable analysis. There were 31 stillbirths and early neonatal deaths (3.5%), and 119 babies (13.4%) were born at a low birth weight. Stillbirth or early neonatal death was significantly associated with no antenatal care in multivariable analysis.

Conclusions

Women and babies in this study experienced multiple risk factors for poor outcomes in the postpartum period. Postnatal care should be strengthened in order to address the dominant risks to mothers and babies, including socioeconomic challenges, HIV and hypertension, and risks to mental health. Tools to identify mothers and babies at risk of postnatal complications would allow limited resources to be allocated where they are most needed.

Supporting retention in HIV care through a holistic, patient-centred approach: a qualitative evaluation

BACKGROUND

HIV is a complex disease which affects different facets (social, economic, physical, emotional and spiral) of an individual's life, making the goals of retention in care and adherence to treatment difficult to achieve. Holistic patient-centred approaches to providing care for people living with HIV bind together economic, social, emotional and physiological aspects and have the potential to improve retention in care and ART adherence. Case management is a holistic, patient-centred approach which is increasingly being implemented in the management of chronic illnesses.

METHODS

We conducted a qualitative study based on semi-structured interviews with key informants (retention officers and social auxiliary workers) and patients. A total of 60 patients and 17 KIs (11 retention officers and 6 social auxiliary workers) participated in the study. The study was conducted in Johannesburg District, Gauteng province, South Africa. Key informants (KIs) and patients were drawn from 8 health facilities located in four management clusters of the district.

RESULTS

The findings identified facilitators and barriers to adherence and retention in care, and demonstrated that case management offered holistic, patient-centred services which patients considered to be beneficial to their well-being and helped them overcome some of these barriers. The success of case management was driven by its holistic and patient-centred approach, which extended the focus to patients' non-clinical needs which impact on their quality of life. Complex interacting barriers and facilitators at different levels influenced implementation of the model and its outcomes.

CONCLUSION

Holistic approaches such as case management have a strong potential to improve retention in care and adherence to ART. HIV is a complex disease which impacts different facets of an individual's life, hence requires holistic care to address all facets. Health systems need to transition towards holistic care to ensure that some patients do not slip through the cracks, improve patient outcomes and efficiency.

Contextual factors affecting the integration of community health workers into the health system in Limpopo Province, South Africa

Background

Community health workers (CHWs) are an essential cadre in the health systems of many low- and middle-income countries. These workers provide a wide variety of services and are key to ongoing processes of task shifting within human immunodeficiency virus programmes in particular. Ward-based outreach teams (WBOTs) are South Africa’s latest iteration of the CHW programme and have been introduced as part of the National Department of Health’s Primary Health Care Re-engineering programme.

Methods

In order to assess the perceived effectiveness of the WBOTs in supporting the ongoing rollout of antiretroviral therapy, tuberculosis care and patient support, we conducted a qualitative investigation focusing on the perceived successes and challenges of the programme among CHWs, community leaders, healthcare workers and community members in the Mopani district, Limpopo province, South Africa.

Results

The CHW programme operates across these contexts, each associated with its own set of challenges and opportunities.

Conclusions

While these challenges may be interrelated, a contextual analysis provides a useful means of understanding the programme’s implementation as part of ongoing decision-making processes.

CD4 testing after initiation of antiretroviral therapy: Analysis of routine data from the South African HIV programme

Background

People living with HIV (PLHIV) who have low CD4 counts require advanced clinical care (ACC) to minimise morbidity and mortality risk. These patients include immunological non-responders (INRs) with low CD4 counts despite a suppressed viral load.

Objectives

To determine the proportion of patients with low CD4 counts after antiretroviral therapy (ART) initiation and to describe INRs within that group.

Methods

Routine Three Interlinked Electronic Registers.Net (TIER.Net) data from four South African districts were analysed for adult PLHIV on ART > 12 months. Immunological non-responders were defined as patients on ART > 4 years who were virally suppressed (viral load < 1000 copies/mL) with a CD4 count ≤ 350 cell/mm³.

Results

Baseline CD4 was recorded for 80.9% of the 869 571 patients newly initiating ART, with 37.2% of those starting ART since 2017 having baseline counts ≤ 200 cells/mm³. Amongst all 1 178 190 patients on ART, only 46.5% had a CD4 test after ART initiation and of these, 14.3% had CD4 ≤ 200 cells/mm³. This proportion was highest amongst patients on ART ≤ 2 years (19.7%) (p < 0.001). Amongst virally suppressed patients, 20.0% were INRs. Immunological non-response was significantly more likely amongst patients on second-line ART (adjusted odds ratio [aOR] 1.79), those aged 35-45 and ≥ 45 years (aOR 1.15 and 1.50, respectively), males (aOR 2.28) and patients with confirmed TB (aOR 2.49), and was significantly less likely in cases with higher baseline CD4 count (aOR 0.35).

Conclusion

CD4 testing subsequent to ART initiation is poorly implemented and there is a notable proportion of patients with low CD4 counts. Guidelines regarding CD4 testing and ACC need to be more widely implemented to identify patients with low CD4 counts and improve their outcomes.

Same-day antiretroviral therapy initiation for HIV-infected adults in South Africa: Analysis of routine data

Same-day initiation (SDI) of antiretroviral therapy (ART) has been recommended to improve ART programme outcomes in South Africa since August 2017. This study assessed implementation of SDI over time in two South African districts, describing the characteristics of same-day initiators and evaluating the impact of SDI on retention in ART care. Routine data were analysed for HIV-infected adults who were newly initiating ART in Johannesburg or Mopani Districts between October 2017 and June 2018. Characteristics of same-day ART initiators were compared to later initiators, and losses to follow-up (LTFU) to six months were assessed using Kaplan Meier survival analysis and multivariate logistic regression. The dataset comprised 32 290 records (29 964 from Johannesburg and 2 326 from Mopani). The overall rate of SDI was 40.4% (n = 13 038), increasing from 30.3% in October 2017 to 54.2% in June 2018. Same-day ART initiators were younger, more likely to be female and presented with less advanced clinical disease than those initiating treatment at later times following diagnosis (p<0.001 for all). SDI was associated with disengagement from care: LTFU was 30.1% in the SDI group compared to 22.4%, 19.8% and 21.9% among clients initiating ART 1–7 days, 8–21 days and ≥22 days after HIV diagnosis, respectively (p<0.001). LTFU was significantly more likely among clients in Johannesburg versus Mopani (adjusted odds ratio (aOR) = 1.43, p<0.001) and among same-day versus later initiators (aOR = 1.45, p<0.001), while increasing age reduced LTFU (aOR = 0.97, p<0.001). In conclusion, SDI has increased over time as per national guidelines, but there is serious concern regarding the reduced rate of retention among same-day initiators. Nevertheless, SDI may result in a net programmatic benefit provided that interventions are implemented to support client readiness for treatment and ongoing engagement in ART care, particularly among younger adults in large ART programmes such as Johannesburg.

Baseline CD4 and mortality trends in the South African human immunodeficiency virus programme: Analysis of routine data

Background

Despite widespread availability of antiretroviral therapy (ART) in South Africa, there remains a considerable burden of human immunodeficiency virus (HIV)-related morbidity and mortality.

Objectives

To describe ART initiation and outcome trends over time, with a focus on clients presenting with advanced HIV-infection, so as to identify interventions to reduce morbidity and mortality.

Methods

Routine TIER.Net data from HIV-infected adults who had a documented baseline CD4 count and were newly initiating ART in Johannesburg or Mopani districts from 2004 to 2017 were analysed. Trends in baseline CD4 count and 5-year mortality were investigated and the population initiating ART with CD4 < 200 cells/mm³ was described.

Results

The Johannesburg and Mopani data sets comprised 203 131 and 101 814 records, respectively. Although median CD4 count increased over time, the proportion of initiations at CD4 < 200 cells/mm³ in 2017 remained high (Johannesburg 39%, Mopani 35%). Mortality was significantly increased among clients with CD4 < 200 compared to those with higher baseline counts (p < 0.001). Even though mortality among clients with low CD4 declined over time, likely because of improved drug regimens, in 2016-2017 mortality was still significantly increased among these clients (p < 0.001). Delivery of cotrimoxazole prophylaxis to clients with low CD4 declined over time to < 30% in 2017 and was associated with clinical stage. Presentation with CD4 < 200 cells/mm³ was associated with older age, male gender and hospitalisation.

Conclusion

A concerningly large proportion of South Africans still initiate ART at low CD4 counts. This is associated with increased mortality and requires targeted interventions to improve delivery of prophylactic regimens and early engagement in care.

Provision of HIV services by community health workers should be strengthened to achieve full programme potential: a cross-sectional analysis in rural South Africa

OBJECTIVE

South Africa's community health workers (CHWs) provide a bridge between the primary healthcare (PHC) facility and its community. We conducted a cross-sectional analysis to determine the contribution of the community-based HIV programme (CBHP) to the overall HIV programme.

METHODS

We collected service provision data from the daily activity register of CHWs attached to 12 PHC facilities in rural Mopani District, South Africa. Personal identifiers of individuals referred to the facility for HIV services were recorded and verified against facility routine patient registers to determine the effectiveness of referral.

RESULTS

HIV services were provided on 18 927 occasions; 30% of the total activities performed by CHWs during the study period. CHWs assessed 12 159 individuals for HIV risk (13% coverage of the study population); only 290 (2%) were referred for HIV testing services. Referral was effective in 213 (73%) individuals; evidence of an HIV-positive status was found for 38 (18%) individuals. However, 30 (79%) of these individuals were referred by CHWs despite being on ART. Adherence support was provided during 5657 visits; only one individual was referred for complications. Finally, of the 864 individuals lost to the ART programme, CHWs managed to find 452 (52%) for referral back to the facility; only 241 (53%) of these were (re)initiated on ART.

CONCLUSIONS

Provision of HIV services by CHWs should be strengthened to fully deliver on the programme's potential. Human resource investment, home-based HIV testing and improved tracing models constitute potential strategies to enhance CHWs impact on the HIV programme.

Targeted mentoring for human immunodeficiency virus programme support in South Africa

Background

Mentoring is a required component of health systems strengthening technical assistance interventions in low- and middle-income countries (LMICs). Mentoring is useful because it does not necessarily compromise service delivery and promotes the sharing of newly acquired knowledge and skills. However, there is a lack of research on the implementation of mentoring in the context of the HIV epidemic in southern Africa.

Objectives

This qualitative evaluation focussed on understanding the implementation process of targeted mentoring for clinical practice, data management and pharmacy management, at public health care facilities in South Africa; and on identifying critical factors influencing the effectiveness of mentoring as a technical assistance intervention in this context.

Methods

Purposive sampling was used to select participants from public health facilities in three South African Provinces. Participants were invited to take part in structured interviews. Datawere analysed using thematic analysis, and two core themes were identified: mentoring as knowledge and skills transfer; and mentoring as psychosocial support.

Results

In terms of knowledge and skills transfer, the sequential implementation of proactive and reactive mentoring was critical. Initial proactive mentoring involved mentors initiating training and developing professional relationships with mentees. Thereafter, a reactive mentoring phase allowed mentees to request support when required. This enabled mentors to leverage real-world problems faced by health workers to support their implementation of new knowledge and skills. The availability and accessibility of mentors alongside the relationships between mentors and mentees provided psychosocial support for health care workers which facilitated their self-efficacy in implementing new knowledge and skills.

Conclusion

These findings suggest that the success of mentoring programmes in LMICs may require specific attention to both knowledge transfer and the management of interpersonal relationships.

Understanding health worker data use in a South African antiretroviral therapy register

OBJECTIVE

To evaluate how electronic data management systems affect data use practices in antiretroviral therapy (ART) programs within local health districts, and individual health facilities.

METHODS

We used a data quality audit to establish a baseline of the quality of data in the electronic register alongside in-depth interviews with health workers and managers, to understand perceptions of data quality, data use by facility staff and challenges affecting data use.

RESULTS

The findings provide a four-level continuum of data use that can be applied to other settings and recommendations for optimising facility-level data use.

CONCLUSION

By defining four levels of data use our findings suggest the potential to encourage a structured process of moving from passive data use, to more active and engaged data use, where data could be used to anticipate patient behaviour and link that behaviour to differentiated care plans.

Fidelity of HIV programme implementation by community health workers in rural Mopani district, South Africa: a community survey

BACKGROUND

South Africa has implemented a community health programme delivered by community health workers (CHWs) to strengthen primary healthcare services. Provision of community Human Immunodeficiency Virus (HIV) services constitutes an important component of this programme. To support effectiveness, we assessed fidelity of HIV programme implementation by CHWs from the community's perspective in a rural South African setting.

METHODS

A cross-sectional study was conducted targeting 900 randomly selected households in twelve wards of two sub-districts (Greater Giyani and Greater Letaba) of Mopani District (Limpopo Province, South Africa). Questionnaires were administered to the traditionally most appropriate adult member of the household. Included were questions related to the four standard components to measure implementation fidelity against local guidelines: coverage, frequency, duration and content of HIV programme implementation.

RESULTS

Participants were enrolled at 534 households; in most other cases there was nobody or no adult member at home (n = 291). Reported coverage of 55% (141/253) and a frequency of 47% (66/140) were higher in Greater Giyani as compared to Greater Letaba (44%; 122/278 and 29%; 33/112, respectively, p = 0.007 for both comparisons). Coverage was not associated with the distance from the participant's household to the facility (p = 0.93). Duration of programme delivery was reported to be high, where all CHW visits (253/253; 100%) were conducted within the last 6 months and the content delivered was adequate (242/253; 96%). Individuals reporting a CHW visit were more likely to know their HIV status than those not visited (OR = 2.0; 95% CI 1.06-3.8; p = 0.032). Among those visited by the CHW discussion of HIV was associated with knowing the HIV status (OR = 2.2; 95% CI 1.02-4.6; p = 0.044); in particular for women (OR = 2.9; 95% CI 1.5-5.4; p = 0.001).

CONCLUSIONS

This study demonstrates promising HIV programme implementation fidelity by CHWs in rural South Africa. Programme coverage and frequency should be improved whilst maintaining the good levels of duration and content. Resource investment, strengthening of operational structure, and research to identify other facilitators of programme implementation are warranted to improve programme effectiveness and impact.

Qualitative assessment of facilitators and barriers to HIV programme implementation by community health workers in Mopani district, South Africa

South Africa has implemented a community-based HIV programme (CBHP) in its primary healthcare (PHC) re-engineering strategy that aims to improve public healthcare delivery. This CBHP is delivered by ward-based outreach teams (WBOTs); provision of community HIV services comprises an important component of this programme. We conducted an exploratory study to determine the facilitators and barriers to successful implementation of this CBHP in rural Mopani District, South Africa. Focus group discussions were conducted with the community health workers (CHWs) and PHC nurses; participant interviews were conducted with community members who access these health services, community leaders, and social workers. We conducted a thematic content analysis and based on the key themes reported, we identified the Consolidated Framework for Implementation Research, consisting of five domains, as the most appropriate model to interpret our findings. First, in terms of intervention characteristics, community members generally valued the HIV services provided, but the variable needs impacted on programme implementation. Outer setting challenges include inability to meet the need of patients as a result of stigma, non-disclosure of HIV status and social factors. In terms of the inner setting, CHWs were grateful for the equipment and training received but expressed the need for better support of management and the provision of additional resources. With regard to characteristics of the implementers, the CHWs expressed the desire for further training despite reporting having sufficient knowledge to conduct their HIV work. Finally, in terms of the implementation process, the importance of relationship building between CHWs and community members was emphasised. In conclusion, these data underline the positive receipt and potential of the CBHP in this rural district and identify areas to further strengthen the programme. The success and sustainability of the CBHP requires ongoing commitment of resources, training, supervision, and organisational support in order to operate effectively and efficiently.

Breaking Down Barriers to Tell: A Mixed Methods Study of Health Worker Involvement in Disclosing to Children That They Are Living with HIV in Rural South Africa

Disclosing to a child that s/he is living with HIV is necessary to promote adherence to treatment and improve health outcomes. Facilitating disclosure between caregivers and children remains a challenge for health workers. Understanding how health workers are involved in and perceive the disclosure process is integral to engaging with such challenges. We held group discussions with and surveyed 73 physicians, nurses, and counselors across 16 randomly selected facilities in two rural South African health districts, exploring their experiences of supporting disclosure between caregivers and children. Ninety percent of those surveyed agreed that children should be informed of their HIV status. Differences between categories of health workers regarding training, involvement in the disclosure process, and perceived responsibility for disclosure support led to inconsistent disclosure practices within facilities. Disclosure-strengthening interventions must consider the composition of the health worker team and the role that each category of health worker performs in their local settings.

Making ward-based outreach teams an effective component of human immunodeficiency virus programmes in South Africa

The implementation of ward-based outreach teams (WBOTs), comprised of community health workers (CHWs), is one of the three interventions of the South African National Department of Health's (NDoH) Primary Health Care (PHC) Re-engineering strategy for improving health outcomes. CHWs provide a necessary structure to contribute to successful implementation of the human immunodeficiency virus (HIV) programme in four ways: (1) prevention of HIV infection by health education, (2) linkage to care by health education and referrals, (3) adherence support and (4) identification of individuals who are failing treatment. However, CHW programme and HIV programme-specific barriers exist that need to be resolved in order to achieve maximum impact. These include a lack of stakeholder and community support for WBOTs, challenging work and operational environments, a lack of in-depth knowledge and skills, and socio-cultural barriers such as HIV-related stigma. Considering its promising structure, documentation of the WBOT contribution to healthcare overall, and the HIV programme in particular, is urgently warranted to successfully and sustainably incorporate it into the South African healthcare system.

Genital Chlamydia trachomatis and Neisseria gonorrhoeae infections among women in sub-Saharan Africa: A structured review

Chlamydia trachomatis and Neisseria gonorrhoeae constitute major public health problems among women, but the burden of infection in sub-Saharan Africa is poorly documented. We conducted a structured review of the prevalence and incidence of genital, oral and anal C. trachomatis and N. gonorrhoeae infection in women in sub-Saharan Africa. We searched Medline, EMBASE and Web of Science over a 10-year period for studies on epidemiology of genital, oral and anal chlamydial infection and gonorrhoea in women in all countries of sub-Saharan Africa. We assessed geographic and demographic differences in prevalence and incidence of infection; weighted mean prevalence estimates were calculated with a random-effect model. A total of 102 study results were included, with data available for 24/49 of sub-Saharan countries. The weighted prevalence of chlamydial infection was lower among women in community-based studies (3.9%; 95% CI: 2.9-5.1%) than for women recruited at primary healthcare facilities (6.0%; 95% CI: 4.2-8.4%, p < 0.001); the same was observed for gonorrhoea (2.2%; 95% CI: 1.2-4.0% vs. 4.2%; 95% CI: 3.2-5.6%, p < 0.001). Prevalence of Chlamydia among sex workers was 5.5% (95% CI: 4.2-7.3%) and gonorrhoea 7.6% (95% CI: 5.4-11%). Seven studies reported on incidence which varied between 0.75-28 and 2.8-17 per 100 person-years-at-risk for chlamydial infection and gonorrhoea, respectively. Only two studies reported on anal infections and one on oral infection. This overview underscores the considerable incidence and prevalence of genital C. trachomatis and N. gonorrhoeae in women in different settings in sub-Saharan Africa. Better control strategies are warranted to reduce the burden of infection and to prevent long-term complications of these infections.

Delivering HIV services in partnership: factors affecting collaborative working in a South African HIV programme

Background

The involvement of Global Health Initiatives (GHIs) in delivering health services in low and middle income countries (LMICs) depends on effective collaborative working at scales from the local to the international, and a single GHI is effectively constructed of multiple collaborations. Research is needed focusing on how collaboration functions in GHIs at the level of health service management. Here, collaboration between local implementing agencies and departments of health involves distinct power dynamics and tensions. Using qualitative data from an evaluation of a health partnership in South Africa, this article examines how organisational power dynamics affected the operation of the partnership across five dimensions of collaboration: governance, administration, organisational autonomy, mutuality, and norms of trust and reciprocity.

Results

Managing the tension between the power to provide resources held by the implementing agency and the local Departments’ of Health power to access the populations in need of these resources proved critical to ensuring that the collaboration achieved its aims and shaped the way that each domain of collaboration functioned in the partnership.

Conclusions

These findings suggest that it is important for public health practitioners to critically examine the ways in which collaboration functions across the scales in which they work and to pay particular attention to how local power dynamics between partner organisations affect programme implementation.

Evaluation of syndromic management guidelines for treatment of sexually transmitted infections in South African women

OBJECTIVE

To evaluate the performance of three different guidelines for the management of vaginal discharge syndrome (VDS) for women living in a rural setting in South Africa.

METHODS

We conducted a secondary analysis of data from a cross-sectional study in Mopani District, South Africa. The 2015 and 2008 guidelines of the South African Department of Health (DoH) and the most recent WHO guidelines were evaluated for adequate treatment of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis infection.

RESULTS

Of the 489 women included in this analysis, 35% presented with VDS according to the DoH and 30% per WHO definition of VDS. Fifty-six per cent of the women with VDS would be treated adequately for these STI when using the 2015 DoH guideline, whereas 76% (P = 0.01) and 64% (P = 0.35) would receive adequate treatment with the 2008 DoH and WHO guidelines, respectively. Of the symptomatic women who tested negative for all four STI, STI treatment would have been indicated for 36% as per 2015 DoH guideline vs. 69% (P < 0.001) per 2008 DoH and 67% (P < 0.001) per WHO guidelines.

CONCLUSION

A considerable proportion of symptomatic women infected with these common curable STI would receive adequate treatment when using a syndromic management approach, and significant differences exist between the three guidelines. Many symptomatic women without these STI receive broad-spectrum antibiotics, so new approaches are needed to improve syndromic STI control.

Sexual behaviour of women in rural South Africa: a descriptive study

Background

Sexual behaviour is a core determinant of the HIV and sexually transmitted infection (STI) epidemics in women living in rural South Africa. Knowledge of sexual behaviour in these areas is limited, but constitutes essential information for a combination prevention approach of behavioural change and biomedical interventions.

Methods

This descriptive study was conducted in rural Mopani District, South Africa, as part of a larger study on STI. Women of reproductive age (18–49 years) who reported sexual activity were included regardless of the reason for visiting the facility. Questionnaires were administered to 570 women. We report sexual behaviour by age group, ethnic group and self-reported HIV status.

Results

Young women (<25 years) were more likely to visit bars, practice fellatio, have concurrent sexual partners and report a circumcised partner than older women (>34 years); there was no difference for condom use during last sex act (36 % overall). Sotho women were more likely to report concurrent sexual partners whereas Shangaan women reported more frequent intravaginal cleansing and vaginal scarring practice in our analysis. HIV-infected women were older, had a higher number of lifetime sexual partners, reported more frequent condom use during the last sex act and were more likely to have a known HIV-infected partner than women without HIV infection; hormonal contraceptive use, fellatio, and a circumcised partner were less often reported.

Conclusions

This study provides insight into women’s sexual behaviour in a rural South African region. There are important differences in sexual behaviour by age group and ethnicity and HIV status; these should be taken into account when designing tailor-made prevention packages.

The church and paediatric HIV care in rural South Africa: a qualitative study

Religion has substantial - positive and negative - influence on South Africa's HIV context. This qualitative study explored possibilities for positive church engagement in paediatric HIV care in a rural district in Limpopo Province, South Africa. Opinions, attitudes and experiences of various stakeholders including religious leaders, healthcare workers and people infected/affected with/by HIV were investigated through participant observation, semi-structured interviews and focus group discussions. During the research the original focus on paediatric HIV care shifted to HIV care in general in reaction to participant responses. Participants identified three main barriers to positive church engagement in HIV care: (a) stigma and disclosure; (b) sexual associations with HIV and (c) religious beliefs and practices. All participant groups appreciated the opportunity and relevance of strengthening church involvement in HIV care. Opportunities for positive church engagement in HIV care that participants identified included: (a) comprehensive and holistic HIV care when churches and clinics collaborate; (b) the wide social reach of churches and (c) the safety and acceptance in churches. Findings indicate that despite barriers great potential exists for increased positive church engagement in HIV care in rural South Africa. Recommendations include increased medical knowledge and dialogue on HIV/AIDS within church settings, and increased collaboration between churches and the medical sector.

Implementation of an electronic monitoring and evaluation system for the antiretroviral treatment programme in the Cape Winelands district, South Africa: a qualitative evaluation

BACKGROUND

A pragmatic three-tiered approach to monitor the world's largest antiretroviral treatment (ART) programme was adopted by the South African National Department of Health in 2010. With the rapid expansion of the programme, the limitations of the paper-based register (tier 1) were the catalyst for implementation of the stand-alone electronic register (tier 2), which offers simple digitisation of the paper-based register. This article engages with theory on implementation to identify and contextualise enabling and constraining factors for implementation of the electronic register, to describe experiences and use of the register, and to make recommendations for implementation in similar settings where standardisation of ART monitoring and evaluation has not been achieved.

METHODS

We conducted a qualitative evaluation of the roll-out of the register. This comprised twenty in-depth interviews with a diverse sample of stakeholders at facility, sub-district, and district levels of the health system. Facility-level participants were selected across five sub-districts, including one facility per sub-district. Responses were coded and analysed using a thematic approach. An implementation science framework guided interpretation of the data.

RESULTS & DISCUSSION

We identified the following seven themes: 1) ease of implementation, 2) perceived value of an electronic M&E system, 3) importance of stakeholder engagement, 4) influence of a data champion, 5) operational and logistical factors, 6) workload and role clarity, and 7) importance of integrating the electronic register with routine facility monitoring and evaluation. Interpreting our findings through an implementation theory enabled us to construct the scaffolding for implementation across the five facility-settings. This approach illustrated that implementation was not a linear process but occurred at two nodes: at the adoption of the register for roll-out, and at implementation at facility-level.

CONCLUSION

In this study we found that relative advantage of an intervention and stakeholder engagement are critical to implementation. We suggest that without these aspects of implementation, formative and summative outcomes of implementation at both the adoption and coalface stages of implementation would be negatively affected.

Clinical assessment of peripheral neuropathy in HIV-infected children on antiretroviral therapy in rural South Africa

Peripheral neuropathy is a well-known side effect of antiretroviral therapy (ART) in adult patients and is particularly related to the use of nucleoside reverse transcriptase inhibitors. This class of drugs is included in all first-line paediatric ART regimens in Africa, but data on the prevalence of neuropathy in children are scarce. In this cross-sectional study, 182 HIV-infected children on ART in rural South Africa were assessed for peripheral neuropathy using the neuropathy symptom score (NSS) and neuropathy disability score (NDS). Peripheral neuropathy was defined as NSS ≥ 5 or NDS ≥ 3. Neurological assessment was completed for 174 children (96 %). Symptoms of neuropathy were reported in NSS by 48 children (28 %; 95 % confidence interval (CI) 21-34 %), and signs were observed in NDS in 25 children (14 %; 95 % CI 12-16 %). A diagnosis of peripheral neuropathy was established in 42 children (24 %; 95 % CI 18-30 %). Independent risk factors for peripheral neuropathy were co-trimoxazole prophylaxis (adjusted odds ratio 0.45; 95 % CI 0.21-0.95, p = 0.036) and didanosine use (adjusted odds ratio 12; 95 % CI 1.3-116, p = 0.030).

CONCLUSION

Peripheral neuropathy as determined by clinical assessment is a common condition in African children on ART.

Ocular infections in sub-Saharan Africa in the context of high HIV prevalence

Healthy eyes and good vision are important determinants of populations' health across the globe. Sub-Saharan Africa is affected by simultaneous epidemics of ocular infections and human immunodeficiency virus (HIV). Ocular infection and its complications, along with cataract and ocular trauma, are common conditions in this region with great impact on daily life. In this review, we discuss the epidemiology, clinical manifestations and microbial aetiology of the most important infectious ocular conditions in sub-Saharan Africa: conjunctivitis, keratitis and uveitis. We focus specifically on the potential association of these infections with HIV infection, including immune recovery uveitis. Finally, challenges and opportunities for clinical management are discussed, and recommendations made to improve care in this neglected but very important clinical field.

High seroprevalence of human herpesviruses in HIV-infected individuals attending primary healthcare facilities in rural South Africa

Seroprevalence data of human herpesviruses (HHVs) are limited for sub-Saharan Africa. These are important to provide an indication of potential burden of HHV-related disease, in particular in human immunodeficiency virus (HIV)-infected individuals who are known to be at increased risk of these conditions in the Western world. In this cross-sectional study among 405 HIV-infected and antiretroviral therapy naïve individuals in rural South Africa the seroprevalence of HHVs was: herpes simplex virus type 1 (HSV-1) (98%), herpes simplex virus type 2 (HSV-2) (87%), varicella zoster virus (VZV) (89%), and 100% for both Epstein-Barr virus (EBV) and cytomegalovirus (CMV). Independent factors associated with VZV seropositivity were low educational status and having children. Lack of in-house access to drinking water was independently associated with positive HSV-1 serostatus, whereas Shangaan ethnicity was associated with HSV-2 seropositivity. Increasing age was associated with higher IgG titres to both EBV and CMV, whereas CD4 cell count was negatively associated with EBV and CMV IgG titres. Moreover, IgG titres of HSV-1 and 2, VZV and CMV, and CMV and EBV were positively correlated. The high HHV seroprevalence emphasises the importance of awareness of these viral infections in HIV-infected individuals in South Africa.

Efavirenz-induced gynecomastia in a prepubertal girl with human immunodeficiency virus infection: a case report

BACKGROUND

Prepubertal gynecomastia is a rare condition and most frequently classified as idiopathic. In HIV-infected adults gynecomastia is a recognised but infrequent side-effect of antiretroviral treatment (ART) and mostly attributed to efavirenz use. Gynecomastia should be distinguished from pseudogynecomastia as part of the lipodystrophy syndrome caused by Nucleoside Reverse Transcriptase Inhibitors (NRTIs) to avoid incorrect substitution of drugs. In the medical literature only five cases of prepubertal gynecomastia in children taking ART are described and underlying pathogenesis was unknown. The occurrence of adverse effects of ART may interfere with therapy adherence and long-term prognosis and for that reason requires attention. We report the first case of prepubertal gynecomastia in a young girl attributed to efavirenz use.

CASE PRESENTATION

A seven-year-old African girl presented with true gynecomastia four months after initiation on ART (abacavir, lamivudine, efavirenz). History, physical examination and laboratory tests excluded known causes of gynecomastia and efavirenz was considered as the most likely cause. Six weeks after withdrawal of efavirenz the breast enlargement had completely resolved.

CONCLUSIONS

Efavirenz-induced gynecomastia may occur in children as well as in adults. With the increasing access to ART, the possibility of efavirenz-exposure and the potential occurrence of its associated side-effects may be high. In resource-poor settings, empirical change from efavirenz to nevirapine may be considered, providing no other known or alarming cause is identified, as efavirenz-induced gynecomastia can resolve quickly after withdrawal of the drug. Timely recognition of gynecomastia as a side-effect of efavirenz is important in order to intervene while the condition may still be reversible, to sustain adherence to ART and to maintain the sociopsychological health of the child.
