    Isoniazid preventive therapy completion between July-September 2019: A comparison across HIV differentiated service delivery models in Uganda
    (PLOS One Publishers, 2024-01-02) Levicatus, Mugenyi; Proscovia, Mukonzo Namuwenge; Simple, Ouma; Baker, Bakashaba; Mastula, Nanfuka; Jennifer, Zech; Collins, Agaba; Andrew, Mijumbi Ojok; Fedress, Kaliba; John, Bossa Kato; Ronald, Opito; Yunus, Miya; Cordelia, Katureebe; Yael, Hirsch-Moverman
    Background Tuberculosis (TB) remains the leading cause of death among people living with HIV (PLHIV). To prevent TB among PLHIV, the Ugandan national guidelines recommend Isoniazid Preventive Therapy (IPT) across differentiated service delivery (DSD) models, an effective way of delivering ART. DSD models include Community Drug Distribution Point (CDDP), Community Client-led ART Delivery (CCLAD), Facility-Based Individual Management (FBIM), Facility-Based Group (FBG), and Fast Track Drug Refill (FTDR). Little is known about the impact of delivering IPT through DSD. Methods We reviewed medical records of PLHIV who initiated IPT between June-September 2019 at TASO Soroti (TS), Katakwi Hospital (KH) and Soroti Regional Referral Hospital (SRRH). We defined IPT completion as completing a course of isoniazid within 6–9 months. We utilized a modified Poisson regression to compare IPT completion across DSD models and determine factors associated with IPT completion in each DSD model. Results Data from 2968 PLHIV were reviewed (SRRH: 50.2%, TS: 25.8%, KH: 24.0%); females: 60.7%; first-line ART: 91.7%; and Integrase Strand Transfer Inhibitor (INSTI)-based regimen: 61.9%. At IPT initiation, the median age and duration on ART were 41.5 (interquartile range [IQR]; 32.3–50.2) and 6.0 (IQR: 3.7–8.6) years, respectively. IPT completion overall was 92.8% (95%CI: 91.8–93.7%); highest in CDDP (98.1%, 95%CI: 95.0–99.3%) and lowest in FBG (85.8%, 95%CI: 79.0–90.7%). Compared to FBIM, IPT completion was significantly higher in CDDP (adjusted rate ratio [aRR] = 1.15, 95%CI: 1.09–1.22) and CCLAD (aRR = 1.09, 95% CI 1.02–1.16). In facility-based models, IPT completion differed between sites (p<0.001). IPT completion increased with age for FBIM and CCLAD and was lower among female participants in the CCLAD (aRR = 0.82, 95%CI 0.67–0.97). Conclusion IPT completion was high overall but highest in community-based models. Our findings provide evidence that supports integration of IPT within DSD models for ART delivery in Uganda and similar settings.

    Treatment success rate and associated factors among drug susceptible tuberculosis individuals in St. Kizito Hospital, Matany, Napakdistrict, Karamoja region.
    (PLOS One Publishers, 2024-05-14) Ronald, Opito; Keneth, Kwenya; Saadick Mugerwa, Ssentongo; Mark, Kizito; Susan, Alwedo; Baker, Bakashaba; Yunus, Miya; Lameck, Bukenya; Eddy, Okwir; Lilian, Angwech Onega; Andrew, Kazibwe; Emmanuel, Othieno; Fred, Kirya; Peter, Olupot‑Olupot
    Background Tuberculosis (TB) is the leading cause of death among infectious agents globally. An estimated 10million people are newly diagnosed and 1.5 million die of the disease annually. Uganda is among the 30highTB-burdened countries, with Karamoja having a significant contribution of the disease incidence in the country. Control of the disease in Karamoja is complex because a majority of the at-risk population remains mobile; partly because of the nomadic lifestyle. This study, therefore, aimed at describing the factors associated with drug-susceptible TB treatment success rate (TSR) in the Karamoja region. Methods This was a retrospective study on case notes of all individuals diagnosed with and treated for drug-susceptible TB at St. Kizito Hospital Matany, Napak district, Karamoja from 1 2020 to 31 st st Jan December 2021. Data were abstracted using a customized data abstraction tool. Data analyses were done using Stata statistical software, version 15.0. A chi-square test was conducted to compare treatment success rates between the years 2020 and 2021, while Modified Poisson regression analysis was performed at a multivariable level to determine the factors associated with treatment success. Results We studied records of 1234 participants whose median age was 31(IQR: 13–49) years. Children below 15 years of age accounted for 26.2% (n = 323). The overall treatment success rate for the study period was 79.3%(95%CI; 77.0%-81.5%), with a statistically significant variation in 2020 and 2021, 75.4% (422/560) vs 82.4% (557/674) respectively, (P = 0.002). The commonest reported treatment outcome was treatment completion at 52 %(n = 647) and death at wasat10.4%(n=129). Older age, undernutrition (Red MUAC), and HIV-positive status were significantly associated with lower treatment success: aPR = 0.87(95% CI; 0.80–0.94), aPR = 0.91 (95%CI; 0.85–0.98) and aPR = 0.88 (95%CI; 0.78–0.98); respectively. Patients who were enrolled in 2021 had a high prevalence of treatment success compared to those enrolled in 2020, aPR = 1.09 (95%CI; 1.03–1.16). Conclusion TBTSR in Matany Hospital was suboptimal. Older age, poor nutrition, and being HIV-positive were negative predictors of treatment success. We propose integrating nutrition and HIV care into TB programming to improve treatment success
