RESUMO
Introduction: Tuberculosis (TB) remains the leading cause of death among people living with HIV (PLHIV). TB preventive treatment (TPT) can prevent active TB infection in PLHIV for several years after it is completed. During 2019-2021, the six-month course of TPT (using isoniazid) was the most readily available in Uganda; however, program data indicated a TPT program loss to follow-up (LTFU) rate of 12 % during this period. We evaluated factors associated with TPT LTFU among PLHIV in four regional referral hospitals (RRHs) in Uganda from 2019 to 2021. Methods: We abstracted program data from TPT registers on patient LTFU at Masaka, Mbale, Mubende, and Jinja RRHs. Additional data collected included client demographics, duration on HIV antiretroviral therapy (ART), year of TPT initiation, adherence, and point of entry. LTFU was defined as the failure to finish six consecutive months of isoniazid without stopping for more than two months at a time. We conducted bivariate analysis using the chi-square test for independence. Variables with p < 0.05 in bivariate analysis were included in a logistic regression model to establish independent factors associated with LTFU. Results: Overall, 24,206 clients were started on TPT in the four RRHs. Their median age was 40 years (range, 1-90 years), and 15,962 (66 %) were female. A total of 22,260 (92 %) had TPT adherence >95 %. Independent factors associated with LTFU included being on ART for <3 months (AOR: 3.1, 95 % CI: 2.1-4.5) and 20-24 years (AOR: 4.7, 95 % CI: 1.9-12) or 25-29 years (AOR: 3.3, 95 % CI: 1.3-8.2) compared to 15-19 years. Conclusions: PLHIV just starting ART and young adults had higher odds of being LTFU from TPT during 2019-2021 in the four RRHs. Close follow-up of PLHIV aged 20-29 years and those newly initiated on ART could improve TPT completion.
RESUMO
Background: Diarrheal diseases, are major concerns for Ugandan children; persistent in Obongi District despite high rotavirus vaccination rates (2019-2021). The district recorded the country's highest annual acute watery diarrhea (AWD) incidence from 2017 to 2021. Our study, conducted in April 2022, assessed AWD risk factors among 0-59-month-old children in Obongi. Methods: We conducted a 1:2 (193:386) unmatched case-control study. A case was a child (0-59 months) with ≥ 3 loose/liquid stools/day, negative malaria/pneumonia tests, residing in Itula/Parolinya subcounty from 1 to 30 April 2022. Medical records from 10 facilities were reviewed. Simple random sampling identified cases, who were interviewed, and controls were randomly chosen from non-AWD neighboring households. Child health cards provided vaccination details. We used logistic regression to identify factors associated with AWD. Results: Among 193 cases and 386 controls, 104 (54 %) cases and 183 (47 %) controls were male, 58 (30 %) cases and 127 (33 %) controls were aged 12-23 months, 187 (97 %) cases and 369 (96 %) controls had received at least one dose of rotavirus vaccine, 58 (30 %) cases and 120 (34 %) controls treated drinking water. Comorbidity presence (undernutrition, diabetes, HIV) (AOR = 12; CI: 2.5-53), caregiver's unwashed hands post-toilet (AOR = 3.9; CI: 1.2-13), and borehole vs. piped water (AOR = 4.0; CI: 1.7-9.6) linked to AWD. Conclusion: Modifiable factors, including failure of caregivers to wash their hands with soap after visiting toilets and use of borehole water were associated with AWD, suggesting that community sensitization on handwashing at critical times, using clean water and soap, and expanded use of piped water could reduce AWD incidence in this area.
