Predictors of unsuppressed viral load among adults on follow up of antiretroviral therapy at selected public and private health facilities of Adama town: unmached case-control study.

BACKGROUND: Despite the scale up of antiretroviral therapy (ART), unsuppressed viral load among population taking ART in private and public health facilities is still a public health concern increasing the risk of treatment failure. Studies comprehensively assessing significant predictors of non-suppressed viral load among patients on follow up of AR in public and private health facilities are limited. The objective of the study was to identify predictors of unsuppressed viral load among adult patients taking antiretroviral therapy at selected public and private health facilities of Adama town, East shewa zone, Ethiopia. METHODS: An unmatched case-control study was conducted from April 15 /2021 to May 20/2021. A total sample size of 347 patients consisting 116 cases and 231 controls was selected from electronic database among patients who started ART from September 2015 to August 2020. Data were collected using checklist from patient medical records and analyzed by SPSS. The association of dependent and independent variables was determined using multivariate analysis with 95% confidence interval and P - value in logistic regression model to identify independent predictors. RESULT: From the total 347 participants, 140 (40.3%) of them were males and 207 (59.7%) were females. In multivariate logistic regression, CD4 count < 100 [(AOR:1.22, 95% CI: 1.4-7.3)], CD4 100-200[(AOR: 2.58 95% CI: 1.06-8.28)], Fair Adherence [(AOR: 2.44, 95% CI: 1.67-4.82)], poor adherence [(AOR: 1.11, 95% CI: 1.7-6.73)], History of Cotrimoxazole Therapy (CPT) use and not used [(AOR: 2.60, 95% CI: 1.23-5.48)] and History of drug substitution [(AOR:. 361, 95% CI: .145-.897)] were independent predictors of unsuppressed viral load with the p-value less than 0.05. CONCLUSION AND COMMENDATION: In this study, Baseline CD4, adherence, History of CPT used and history of drug substitution was predictors of unsuppressed viral load. Monitoring immunological response through scheduled CD4 tests is essential to maintain immunity of the patients preventing diseases progression. Intensive adherence support and counseling should conclusively be provided through effective implementation of ART programs by providers would enhance viral suppression ensuring the quality of care and treatment.

The immunological status of newly diagnosed tuberculosis patients co-infected with human immunodeficiency virus-1 in Adama Hospital, Ethiopia.

BACKGROUND: Tuberculosis remains a public health problem in patients with human immunodeficiency virus infection in sub-Saharan Africa. Both diseases form a lethal combination, each speeding the progress of the other. OBJECTIVE: The aim of this study was to assess the prevalence of HIV infection in newly diagnosed tuberculosis patients in Adama hospital. METHODS: Blood and sputum samples were collected from adult newly diagnosed tuberculosis patients. Sera were screened for anti-HIV antibody using rapid HIV test kits based on the National testing algorithm. The CD4 and CD8 T-cell subsets were determined using flow cytometry and the ratio of CD4+ and CD8+ were estimated using FACScan. All sputum specimens collected on three consecutive days from patients attending the tuberculosis clinic were screened for acid fast bacilli using smear microscopy. RESULTS: The seroprevalence of HIV among 258 patients with newly diagnosed TB was 26.4%. The median CD4 T cell count of HIV negative and HIV positive TB patients were 702 cells/mm3 and 233 cells/mm3. respectively (P < 0.05). Of the TB patients, 35.7% had extrapulmonary TB and 20% were smear-positive pulmonary TB. The CD4/CD8 ratio in HIV negative patients was 1.33 cells/mm3 compared to the 0.29 cells/mm3 in HIV positive patients. Of the 68 HIV positive TB patients. 58(85.3%) were not aware of their HIV serostatus prior to the screening in the current study. CONCLUSION: In the current study the HIV seroprevalence was 26.4%. The median CD4 count was very low in the TB/HIV co-infected individuals than those infected with TB alone. Majority of the HIV infected individuals were not aware of their serostatus. Provider initiated HIV/AIDS counseling and testing in TB clinics should be strengthened
