Gender disparities operate in opposite directions for hospitalizations and mortality among individuals receiving long-term ART in rural Uganda.

OBJECTIVES: We conducted an analysis to determine if differences in health-seeking behaviour can explain gender disparities in mortality among long-term survivors receiving antiretroviral therapy (ART) in rural Uganda. METHODS: From June 2012 to January 2014, we enrolled patients receiving a first-line ART regimen for at least 4 years without previous viral load (VL) testing in Jinja, Uganda. We measured HIV VL at study entry. We switched participants to second-line therapy, if VL was ≥ 1000 copies/mL on two measurements, and followed participants for 3 years. We collected clinical and behavioural data at enrolment and every 6 months after that. We used Poisson regression to examine factors associated with hospitalizations and Cox proportional hazards modelling to assess mortality to September 2016. RESULTS: We enrolled 616 participants (75.3% female), with a median age of 44 years and a median duration of ART use of 6 years. Of these, 113 (18.3%) had VLs ≥ 1000 copies/mL. Hospitalizations occurred in 101 participants (7% of men vs. 20% of women; P < 0.001). A total of 22 (3.6%) deaths occurred, 9% of men vs. 2% of women (P < 0.001). Multivariate modelling revealed that mortality was associated with age [adjusted hazard ratio (AHR) = 1.07 per year increase; 95% confidence interval (CI): 1.01-1.13], male gender (AHR = 2.57; 95% CI 1.06-6.23) and time-updated CD4 counts (AHR = 0.67 per 100 cell increment; 95% CI: 0.52-0.88). Virological failure was not associated with mortality (P = 0.762). CONCLUSION: Female patients receiving ART in rural Uganda were three times more likely to be hospitalized than men, but male mortality was nearly four times higher. Facilitating care for acute medical problems may help to improve survival among male ART patients.

Lack of effectiveness of adherence counselling in reversing virological failure among patients on long-term antiretroviral therapy in rural Uganda.

OBJECTIVES: The current World Health Organization and Uganda Ministry of Health HIV treatment guidelines recommend that asymptomatic patients who have a viral load (VL) ≥ 1000 HIV-1 RNA copies/mL should receive adherence counselling and repeat VL testing before switching to second-line therapy. We evaluated the effectiveness of this strategy in a large HIV treatment programme of The AIDS Support Organisation Jinja in Jinja, Uganda. METHODS: We measured the HIV VL at enrolment, and for participants with VL ≥ 1000 copies/mL we informed them of their result, offered enhanced adherence counselling and repeated the VL measurement after 3 months. All blood samples with VL ≥ 1000 copies/mL were sequenced in the polymerase (pol) region, a 1257-bp fragment spanning the protease and reverse transcriptase genes. RESULTS: One thousand and ninety-one participants were enrolled in the study; 74.7% were female and the median age was 44 years [interquartile range (IQR) 39-50 years]. The median time on antiretroviral therapy (ART) at enrolment was 6.75 years (IQR 5.3-7.6 years) and the median CD4 cell count was 494 cells/µL (IQR 351-691 cells/µL). A total of 113 participants (10.4%) had VLs ≥ 1000 copies/mL and were informed of the VL result and its implications and given adherence counselling. Of these 113 participants, 102 completed 3 months of follow-up and 93 (91%) still had VLs ≥ 1000 copies/mL. We successfully genotyped HIV for 105 patients (93%) and found that 103 (98%) had at least one mutation: eight (7.6%) had only one mutation, 94 (89.5%) had two mutations and one sample (1%) had three mutations. CONCLUSIONS: In this study, enhanced adherence counselling was not effective in reversing virologically defined treatment failure for patients on long-term ART who had not previously had a VL test.

Knowledge, attitudes and practices on childhood TB among healthcare workers.

BACKGROUND: Increasing childhood TB case detection requires the deployment of diagnostic services at peripheral healthcare level. Capacity and readiness of healthcare workers (HCWs) are key to the delivery of innovative approaches.METHODS: In 2019, HCWs from five district hospitals (DHs) and 20 primary healthcare centres (PHCs) in Cambodia, Cameroon, Cote d´Ivoire, Sierra Leone and Uganda completed a self-administered knowledge-attitudes-practices (KAP) questionnaire on childhood TB. We computed knowledge and attitudes as scores and identified HCW characteristics associated with knowledge scores using linear regression.RESULT: Of 636 eligible HCWs, 497 (78%) participated. Median knowledge scores per country ranged between 7.4 and 12.1 (/18). Median attitude scores ranged between 2.8 and 3.3 (/4). Between 13.3% and 34.4% of HCWs reported diagnosing childhood with (presumptive) TB few times a week. Practising at PHC level, being female, being involved in indirect TB care, having a non-permanent position, having no previous research experience and working in Cambodia, Cameroon, Cote d´Ivoire and Sierra Leone as compared to Uganda were associated with a lower knowledge score.CONCLUSION: HCWs had overall limited knowledge, favourable attitudes and little practice of childhood TB diagnosis. Increasing HCW awareness, capacity and skills, and improving access to effective diagnosis are urgently needed.
