Measuring PMTCT effectivenss through HIV free survival in children under 2 years

Background: The prevalence of HIV was greater than 30% in the Free State province in South Africa and PMTCT services were widely available at the time the guidelines recommended nevirapine in labour and to the child postpartum. Aim: The aim was to determine the effectiveness of the PMTCT program in the Free State by measuring HIV transmission and HIV-free survival in children less than two years of age. Variables associated with HIV transmission and HIV-free survival including PMTCT uptake by mother, demographic characteristics, type of delivery and breastfeeding status were investigated. Methods: This was a secondary analysis of data collected from a cross sectional community household survey, using multistage cluster sampling. The population was all women who had given birth to a child in the two years prior to the study in the catchment area of three sub-districts that were randomly selected in Free State. All mothers were anonymously tested for HIV and if infected the child was also tested. Trained field workers interviewed mothers, identified children who had died and collected data on variables that could be related to transmission and survival. Logistic regression was used to determine risk factors

Timing of pregnancy, postpartum risk of virologic failure and loss to follow-up among HIV-positive women.

BACKGROUND: We assessed the association between the timing of pregnancy with the risk of postpartum virologic failure and loss from HIV care in South Africa. METHODS: The incidence of virologic failure (two consecutive viral load measurements of >1000 copies/ml) and loss to follow-up (>3 months late for a visit) during 24 months postpartum were assessed using Cox proportional hazards modelling. RESULTS: The rate of postpartum virologic failure was higher following an incident pregnancy on ART [adjusted hazard ratio 1.8, 95% confidence interval (CI): 1.1-2.7] than among women who initiated ART during pregnancy. This difference was sustained among women with CD4 cell count less than 350 cells/μl at delivery (adjusted hazard ratio 1.8, 95% CI: 1.1-3.0). Predictors of postpartum virologic failure were being viremic, longer time on ART, being 25 or less years old and low CD4 cell count and anaemia at delivery, as well as initiating ART on stavudine-containing or abacavir-containing regimen. There was no difference postpartum loss to follow-up rates between the incident pregnancies group (hazard ratio 0.9, 95% CI: 0.7-1.1) and those who initiated ART in pregnancy. CONCLUSION: The risk of virologic failure remains high among postpartum women, particularly those who conceive on ART. The results highlight the need to provide adequate support for HIV-positive women with fertility intention after ART initiation and to strengthen monitoring and retention efforts for postpartum women to sustain the benefits of ART

Treatment initiation among persons diagnosed with drug resistant tuberculosis in Johannesburg, South Africa

In South Africa, roughly half of the drug-resistant TB cases diagnosed are reported to have been started on treatment. We determined the proportion of persons diagnosed with rifampicin resistant (RR-) TB who initiated treatment in Johannesburg after the introduction of decentralized RR-TB care in 2011

Health-related quality of life and psychological distress among adults in Tanzania: a cross-sectional study

Little data is available on health-related quality of life (HRQoL) and mental health of the general population in Tanzania. We aimed to describe HRQoL and level of psychological distress among adults in Mbeya and Songwe Regions of Tanzania. Methods We conducted a cross-sectional study between April and October 2019 in Mbeya and Songwe Regions. Data were collected using the Medical Outcomes Short Form-36 (SF-36) questionnaire and the Page Kessler Psychological Distress Scale (K10). We described demographic characteristics of participants and used log-binomial regression to identify participant characteristics associated with psychological distress (K10 score ≥ 20). Results A total of 393 adults were enrolled. The participants had a median age of 29 years (IQR 23–40) and 54.2% were male. Participants reported a physical component summary score (PCS) with a mean of 54.7 (SD7.1) and a mental component summary score (MCS) with a mean of 55.5 (SD5.1). Older participants (≥ 40 year) and those that were divorced/widowed reported lower physical functioning, energy/vitality and emotional well-being compared to their counterparts ( p < 0.05). In terms of psychological distress, majority of participants (78.4%; 305/389) reported that they were likely to be well (K10 score < 20), while 13.4% (52/389) reported to have mild (K10 score 20–24), 5.7% (22/389) moderate (K10 score 25–29), and 2.6% (10/389) severe (K10 score ≥ 30) psychological distress. Conclusions Physical function and mental well-being in this adult population from Tanzania were lower than that reported in other similar research in Tanzania and other African countries. This study provides valuable references for other research initiatives and clinical services in this region

Who is providing HIV testing services? The profile of lay counsellors providing HIV testing services in Johannesburg, South Africa in the treat-all era

Abstract Background Lay counsellors are critical in sustaining access to HIV testing services (HTS) and psychosocial support for persons living with HIV (PLHIV). We aimed to describe the professional and psychosocial profiles of lay counsellors in primary healthcare (PHC) clinics in Johannesburg, South Africa under the universal-test-and-treat (UTT) policy context. Methods We conducted a descriptive analysis of a cross-sectional survey among adult (≥ 18 years) lay counsellors from 20 PHC facilities (2–3/ clinic) in Johannesburg, South Africa. Consenting counsellors were interviewed between June 2018 and March 2019. We report on counsellors’ demographic profiles, training, work experience, and mental and emotional well-being. Results Overall, 55 consenting adult (≥ 18 years) lay counsellors (92.7% female, median age 37 years, interquartile range [IQR]: 33–44, and 27.3% HIV diagnosed) were surveyed. Most (85.5%) were Department of Health lay counsellors receiving a volunteer stipend at the time. Overall, 56.4% had been working as counsellors for five years or longer. The majority (87%) had completed the National HIV Testing Services Policy Guidelines-recommended 10-day basic counselling training, but 45.2% had not completed refresher training within the guideline’s required 24 months. Reported operational barriers include lack of designated space for counselling (56.4%), inadequate professional supervision and support (40.7%) and insufficient emotional support (over 56.4%), and 60% were overwhelmed by their workload. A total of 18.2% had major depressive symptoms, and the same proportion scored low for psychological well-being. While most (87.3%) reported moderate job satisfaction, 50.9% actively sought alternative employment. Conclusion Despite lay counsellors’ significant role in delivering HIV care in South Africa, there has been minimal investment in their skills development, emotional support, and integration into the formal health workforce. Counsellors’ persisting unmet psychosocial, training, and professional needs could impact their efficacy in the UTT era

Using intervention mapping in motivational interviewing training to improve ART uptake in Gauteng, South Africa

In South Africa, lay HIV counsellors are at the forefront of many HIV-related behavioural interventions. However, they have limited formal counselling training and little ongoing in-service support, leading to considerable variability in approaches to counselling. We describe the use of Intervention Mapping to develop a motivational interviewing counselling training and support program, titled "Thusa-Thuso - helping you help", for lay HIV counsellors practising in primary health care clinics in South Africa. The program is contextually relevant, locally-produced, scalable, and is designed to impart sustained motivational interviewing counselling skills in lay HIV counsellors for improved antiretroviral therapy (ART) uptake in the universal-test-and-treat era

Impact of Xpert MTB/RIF and decentralized care on linkage to care and drug-resistant tuberculosis treatment outcomes in Johannesburg, South Africa

Abstract Background In 2011, South Africa improved its ability to test for rifampicin-resistant TB (RR-TB) by introducing GeneXpert MTB/RIF. At the same time, the South African National TB program adopted a policy decentralized, outpatient treatment for drug resistant (DR-) TB. We aim to analyze the impact of these changes on linkage to care and DR-TB treatment outcomes. Methods We retrospectively matched adult patients diagnosed with laboratory-confirmed RR-TB in Johannesburg from 07/2011–06/2012 (early cohort) and 07/2013–06/2014 (late cohort) with records of patients initiating DR-TB treatment at one of the city’s four public sector treatment sites. We determine the proportion of persons diagnosed with RR-TB who initiated DR-TB treatment and report time to treatment initiation (TTI) before and after the implementation of Xpert MTB/RIF roll-out in Johannesburg, South Africa. We conducted a sub-analysis among those who initiated DR-TB treatment at the decentralized outpatient DR-TB centers to determine if delays in treatment initiation have a subsequent impact on treatment outcomes. Results Five hundred ninety four patients were enrolled in the early cohort versus 713 in the late cohort. 53.8 and 36.8% of patients were diagnosed with multi-drug resistant TB in the early and late cohorts, respectively. The proportion of RR-TB confirmed cases diagnosed by Xpert MTB/RIF increased from 43.4 to 60.5% between the early and late cohorts, respectively. The proportion who initiated treatment increased from 43.1% (n = 256) to 60.3% (n = 430) in the late cohort. Pre-treatment mortality during the early and the late cohort reduced significantly from 17.5 to 5.8% while lost to follow-up remained high. Although TTI reduced by a median of 19 days, from 33 days (IQR 12–52) in the early cohort to 14 days (IQR 7–31) in the late cohort, this did not translate to improved treatment outcomes and we found no difference in terms of treatment success or on-treatment mortality for those that initiated without delay vs. those that deferred initiation. Conclusion Pre-treatment mortality reduced significantly during late Xpert MTB/RIF coverage but there was no significant difference after treatment was initiated. Despite improvements there is still a significant diagnosis and treatment gap for patients diagnosed with RR-TB and improving treatment outcomes remains critical

"I was scared dating… who would take me with my status?"-Living with HIV in the era of UTT and U = U: A qualitative study in Johannesburg, South Africa.

South Africa rolled out Universal Test-and-Treat (UTT) in 2016, extending treatment eligibility to all persons living with HIV (PLHIV). We sought to understand how PLHIV in Johannesburg, South Africa, interpret and experience their HIV status, five years into the UTT era. In May 2021, we conducted in-depth interviews (IDI) (N = 27) with adult (≥18 years) PLHIV referred by HIV counsellors at three peri-urban primary healthcare clinics. We also conducted three focus group discussions (FGDs) (N = 27) with adult PLHIV recruited from clinics or from civil society organisations through snowball sampling. Follow-up interviews were conducted with 29 IDI and FGD participants. Participants were asked to reflect on their HIV diagnosis, what their HIV status meant to them and how, if at all, being HIV-positive affected their lives. Interviews and focus group discussions were audio-recorded, transcribed, translated to English, and analysed using a grounded theory approach. Participants perceived that HIV was common, that PLHIV could live a normal life with antiretroviral therapy (ART), and that ART was widely accessible. However, HIV elicited feelings of guilt and shame as a sexually transmitted disease. Participants used the language of "blame" in discussing HIV transmission, citing their own reckless behaviour or blaming their partner for infecting them. Participants feared transmitting HIV to others and felt responsible for avoiding transmission. To manage transmission anxiety, participants avoided sexual relationships, chose HIV-positive partners, and/or insisted on using condoms. Many participants feared-or had previously experienced-rejection by partners due to their HIV status and reported hiding their medication, avoiding disclosure, or avoiding relationships altogether. Most participants were not aware that undetectable HIV is untransmittable (U = U). Participants who were aware of U = U expressed less anxiety about transmitting HIV to others and greater confidence in having relationships. Despite perceiving HIV as a manageable chronic condition, PLHIV still faced transmission anxiety and fears of rejection by their partners. Disseminating information on U = U could reduce the psychosocial burdens of living with HIV, encourage open communication with partners, and remove barriers to HIV testing and treatment adherence
