Fisherfolk are a most-at-risk population for HIV being prioritized for the scale up of HIV treatment in Uganda. Heavy alcohol use and potential drug use may be a major barrier to treatment adherence for men in this setting. This study examines the prevalence of substance use, and its influence on antiretroviral treatment (ART) adherence, among male fisherfolk on ART in Wakiso District, Uganda. This cross-sectional study included structured questionnaires (N = 300) with men attending HIV clinics near Lake Victoria. Using generalized logistic modeling analyses with a binomial distribution and logit link, we conducted multivariate models to test the association between each alcohol variable (quantity and frequency index, hazardous drinking) and missed pills, adjusting for covariates, and tested for interactions between number of pills prescribed and alcohol variables. Thirty-one percent of men reported sub-optimal adherence. Half (46.7%) reported drinking, of which 64.8% met criteria for hazardous drinking. Illicit drug use was low (6%). In the multivariate model, men with greater scores on the alcohol frequency and quantity index were more likely to report missed pills compared to those reporting no drinking (AOR: 1.60, 95% CI: 1.29-1.97). Hazardous drinking had a greater effect on missed ARV doses among men taking twice daily regimens compared to once daily (AOR: 4.91, 95% CI: 1.68-14.37). Our findings highlight the need for targeted alcohol-reduction interventions for male fisherfolk on ART who drink at high quantities to improve ART adherence and to prevent the known negative health effects of alcohol for HIV-infected individuals.

Background: HIV self-testing (HIVST) can improve HIV-testing rates in 'hard-to-reach' populations, including men. We explored HIVST perceptions, delivery strategies, and post-test experiences among pregnant women and their male partners in Central Uganda. Methods: This was a qualitative study implemented as part of a pilot, cluster-randomized oral HIVST intervention trial among 1,514 pregnant women attending antenatal care services at three health facilities in Central Uganda. The qualitative component of the study was conducted between February and March 2017. We conducted 32 in-depth interviews to document women and men's perceptions about HIVST, strategies used by women in delivering the kits to their male partners, male partners' reactions to receiving kits from their female partners, and positive and negative social outcomes post-test. All interviews were audio-recorded, transcribed verbatim, and analyzed manually following a thematic framework approach. Results: Women were initially anxious about their male partners' reaction if they brought HIVST kits home, but the majority eventually managed to deliver the kits to them successfully. Women who had some level of apprehension used a variety of strategies to deliver the kits including placing the kits in locations that would arouse male partners' inquisitiveness or waited for 'opportune' moments when their husbands were likely to be more receptive. A few (three) women lied about the purpose of the test kit (testing for syphilis and other illnesses) while one woman stealthily took a mucosal swab from the husband. Most men initially doubted the ability of oral HIVST kits to test for HIV, but this did not stop them from using them. Both men and women perceived HIVST as an opportunity to learn about each other's HIV status. No serious adverse events were reported post-test. Conclusion: Our findings lend further credence to previous findings regarding the feasibility of female-delivered HIVST to improve male partner HIV testing in sub-Saharan Africa. However, support for women in challenging relationships is required to minimize potential for deception and coercion.

IntroductionIn Uganda, fisherfolk have an HIV prevalence between 15% and 40%, significantly higher than the national average of 5.5%. Pre-exposure prophylaxis (PrEP) is effective in preventing HIV but faces challenges in uptake and continuation among fisherfolk. This study explores factors influencing PrEP continuation and discontinuation among fisherfolk in Uganda using the Consolidated Framework for Implementation Research (CFIR).MethodsParticipants were recruited from two fishing communities near Entebbe, Uganda. One community received enhanced PrEP support (adherence support, educational workshops and check-in calls), while the other received standard healthcare outreach. Forty fisherfolk (20 who continued PrEP and 20 who discontinued PrEP) were interviewed 6 months after initiating PrEP. Data were analysed using directed content analysis, with high inter-rater consistency. Ethical approval and informed consent were obtained.ResultsFindings highlighted several determinants of PrEP continuation and discontinuation across the CFIR domains. Intervention characteristics such as side effects and the pill burden were significant barriers, particularly for women who reported nausea and stomach issues. Individual characteristics revealed that perceived HIV risk influenced PrEP use, with women’s decisions often influenced by their partners' behaviours and mobility. However, insufficient information and education, especially among women, led to misunderstandings and discontinuation. Inner-setting factors like mobility issues and the distance to healthcare clinics posed significant barriers exacerbated by the geographical isolation of fishing communities. In the outer setting, high HIV prevalence motivated PrEP initiation, but stigma, particularly the misconception that PrEP is an antiretroviral drug used by people living with HIV, led to discontinuation.ConclusionFisherfolk in Uganda encounter multiple barriers to PrEP continuation, with women facing more significant challenges. Enhanced support strategies are essential for improving PrEP adherence and informing future HIV prevention interventions in high-risk populations.

HIV fatalism, or the belief that HIV acquisition and mortality is out of one's control, is thought to contribute to HIV risk in fishing populations in East Africa. The objective of this cross-sectional study was to investigate the association between fatalism and sexual risk behaviours (unprotected sex, engagement in transactional sex), beyond the influence of other known HIV risk factors (e.g. food insecurity, mobility), and identify demographic, psychosocial, and structural correlates of HIV fatalism. Ninety-one men and women living in fishing villages on two islands in Lake Victoria, Uganda completed an interviewer-administered questionnaire after testing HIV-positive during home or community-based HIV testing between May and July 2015. Multivariate logistic regression was used to test the association between HIV fatalism and transactional sex and multivariate linear regression was used to identify demographic, psychosocial, and structural correlates of HIV fatalism. HIV fatalism was significantly associated with a greater likelihood of transactional sex (AOR = 3.07, 95% CI = 1.02-9.23, p = 0.04), and structural barriers to HIV care (e.g. distance to clinic) were significantly associated with HIV fatalism (β = 0.26, SE = 0.12, p = 0.04). Our findings highlight HIV fatalism as a contributor to transactional sex in Ugandan fishing communities, and as a product of broader social and contextual factors, suggesting the potential need for structural HIV interventions in this setting.

Background According to the user instructions from the manufacturer of OraQuick HIV self-test (HIVST) kits, individuals whose kits show one red band should be considered to be HIV-negative, no matter how weak the band is. However, recent reports show potential for a second false weak band after storage, thereby creating confusion in the interpretation of results. In this study, we re-tested individuals whose results were initially non-reactive but changed to weak reactive results to determine their true HIV status. Methods This study was nested within a large, cluster-randomized HIVST trial implemented among pregnant women attending antenatal care and their male partners in central Uganda between July 2016 and February 2017. Ninety-five initially HIV-negative respondents were enrolled into this study, including 52 whose kits developed a second weak band while in storage and 43 whose kits were interpreted as HIV-positive by interviewers at the next follow-up interview. Respondents were invited to return for repeat HIVST which was performed under the observation of a trained nurse counsellor. After HIVST, respondents underwent blood-based rapid HIV testing as per the national HIV testing algorithm (Determine (Abbot Laboratories), STAT-PAK (Chembio Diagnostic Systems Inc.) and Unigold (Trinity Biotech plc.) and dry blood spots were obtained for DNA/PCR testing. DNA/PCR was considered as the gold-standard HIV testing method. Results After repeat HIVST, 90 (94.7%) tested HIV-negative; 2 (2.1%) tested HIV-positive; and 3 (3.2%) had missing HIV test results. When respondents were subjected to blood-based rapid HIV testing, 97.9% (93/95) tested HIV-negative while 2.1% (2/95) tested HIV-positive. Finally, when the respondents were subjected to DNA/PCR, 99% (94/95) tested HIV-negative while 1.1% (1/95) tested HIV-positive. Conclusions Nearly all initially HIV-negative individuals whose HIVST kits developed a second weak band while in storage or were interpreted as HIV-positive by interviewers were found to be HIV-negative after confirmatory DNA/PCR HIV testing. These findings suggest a need for HIV-negative individuals whose HIVST results change to false positive while under storage or under other sub-optimal conditions to be provided with an option for repeat testing to determine their true HIV status.

OBJECTIVES/SPECIFIC AIMS: We investigated the association between relationship power imbalance (which can have a negative impact on HIV prevention) and male partner HIV testing, using baseline data from a HIV self-testing trial in 3 antenatal clinics in central Uganda. METHODS/STUDY POPULATION: Pregnant women with HIV-male partners were recruited and randomized by day into standard of care or intervention (HIV self-testing kits). Analyses were performed in SAS 9.4, with χ 2 tests and p <0.05 for significance. RESULTS/ANTICIPATED RESULTS: In total, 1514 women were recruited (737 standard of care, 777 intervention). Overall, 39.6% of male partners had previously tested for HIV. Among women <26, contributions to expenses differed by partner testing (overall p <0.001, 47.6% of women whose partners tested made no contribution vs. 63.2% of women whose partners did not test). Relationship status differed by partner testing (overall p =0.02, 12.4% of women whose partners tested showed a sometimes difficult relationship vs. 5.7% of women whose partners did not test). Among women 26+, decision making for family visits differed by partner testing (overall p =0.005, 52.9% of women made joint decisions with partners who tested vs. 36.5% whose partners did not test). DISCUSSION/SIGNIFICANCE OF IMPACT: Higher relationship power balance was associated with higher HIV testing among male partners when measured by contribution to expenses and decision making for family visits, but not relationship status. Relationship power balance should be considered when counseling women and men to increase HIV testing.

We aimed to assess the relationship between gender and survival among adult patients newly enrolled on antiretroviral therapy (ART) in Uganda. We also specifically examined the role of antenatal services in favoring women's access to HIV care. From an observational cohort study, we assessed survival and used logistic regression and differences in means to compare men and women who did not access care through antenatal services. Differences were assessed on measures of disease progression (WHO stage and CD4 count) and demographic (age, marital status, and education), behavioral (sexual activity, disclosure to partner, and testing), and clinical variables (hepatitis B and C, syphilis, malaria, and anemia). A mediational analysis that considered gender as the initial variable, time to death as the outcome, initial CD4 count as the mediator, and age as a covariate was performed using an accelerated failure time model with a Weibull distribution. Between 2004 and 2011, a total of 4775 patients initiated ART, and after exclusions 4537 (93.2%) were included in analysis. Men initiating ART were more likely to have a WHO disease stage III or IV (odds ratio: 1.46, 95% confidence interval [CI]: 1.29-1.66), and lower CD4 cell counts compared to women (median baseline CD4 124 cells/mm(3), interquartile range [IQR]: 43-205 versus 147 cells/mm(3), IQR: 68-212, P-value < 0.0001). Men were at an increased risk of death compared to women (hazard ratio: 1.38, 95% CI: 1.03-1.83). Baseline CD4 cell counts accounted for 43% of the increased risk of death in men (95% CI: 22%-113%). Access to care via antenatal services did not explain differences in outcomes. In this cohort there is a marked increase in risk of mortality for men and approximately half of it can be attributed to their later engagement in care. More effort is required to engage men in care in a timely manner.

Mobile populations such as fisherfolk show high HIV incidence and prevalence. We pilot-tested implementation strategies to enhance pre-exposure prophylaxis (PrEP) uptake and adherence in the context of healthcare outreach events in two mainland fisherfolk communities on Lake Victoria, Uganda from September 2021 to February 2022. The implementation strategies included PrEP adherence supporters (selected from PrEP users’ social networks), community workshops (to address misconceptions and stigma, and empower PrEP advocacy), and check-in calls (including refill reminders). PrEP medical records data were collected from 6-months pre-intervention to 6-months post-intervention. Qualitative interviews with 20 PrEP users (10 who continued, 10 who discontinued), 9 adherence supporters, and 7 key partners (providers, community leaders) explored acceptability. Percentages of PrEP initiators (of those eligible) were significantly higher during the intervention (96.5%) than 6-months before the intervention (84.5%), p < 0.0001; percentages of PrEP users who persisted (i.e., possessed a refill) 6-months post-initiation (47.9% vs. 6.7%) and had at least 80% PrEP coverage (based on their medication possession ratio) from the initiation date to 6-months later (35.9% vs. 0%) were higher during versus pre-intervention, p < 0.0001. A comparison fisherfolk community with better healthcare access had lower uptake (78.3%; p < 0.0001) and persistence at 6-months (34.0%; p < 0.001), but higher coverage during the intervention period (70.4%; p < 0.0001). Qualitative data suggested the strategies promoted PrEP use through reduced stigma and misconceptions. The intervention bundle cost was $223.95, $172.98, and $94.66 for each additional person for PrEP initiation, persistence, and coverage, respectively. Enhanced community-based PrEP implementation that fosters a supportive community environment can improve PrEP use in mobile populations without easy access to healthcare. (NCT05084716).

This case report describes an HIV-positive patient with recurrent tuberculosis in Uganda. After several failed courses of treatment, the patient was diagnosed with multi-drug resistant tuberculosis (MDR-TB). As adequate in-patient facilities were unavailable, we advised the patient to remain at home, and he received treatment at home via his family and a community nurse. The patient had a successful clearance of tuberculosis. This strategy of home-based care represents an important opportunity for treatment of patients in East Africa, where human resource constraints and inadequate hospital facilities exist for complex patients at high risk of infection to others.

Among Ugandan fisherfolk, HIV prevalence (with estimates ranging from 15 to 40 %) is higher than in the general population (about 7 %), potentially due to high-risk behaviors and low access to HIV testing and healthcare. We conducted semi-structured interviews on barriers to linkage to care with 10 key stakeholders and 25 fisherfolk within 1–2 months of their testing HIV-positive at clinic outreach events in Ugandan Lake Victoria communities. Interviews were recorded, transcribed, translated, and coded using grounded theory methods. Participants cited low healthcare access and quality of care, mobility, competing needs for work during clinic hours, stigma, and low social support as barriers. Over 10 % of clients screened positive for HIV at outreach events, and only half accessed care. Linkage to care issues may begin with the failure to attract high-risk fisherfolk to testing. New models of HIV testing and treatment delivery are needed to reach fisherfolk.
