Determinants of virological failure among patients on first line highly active antiretroviral therapy (HAART) in Southwest Ethiopia: A case-control study.

Background: Virological failure remains a public health concern among patients with human immunodeficiency virus (HIV) after treatment initiation. Ethiopia is one of the countries that aims to achieve the global target of 90-90-90 that aims to achieve 90% virological suppression, but there is a paucity of evidence on the determinants of virological failure. Therefore, the study is intended to assess determinants of virological treatment failure among patients on first-line highly active antiretroviral therapy (HAART) at Mizan Tepi University Teaching Hospital (MTUTH), Southwest Ethiopia. Method: A hospital-based unmatched case-control study was conducted from 11 November to 23 December 2020, among 146 cases and 146 controls. All cases and controls were selected randomly using computer-generated random numbers based on their medical record numbers. During the document review, data were collected using checklists, entered into Epi-data version 4.0.2, and analyzed by SPSS version 25. A multivariable logistic regression analysis was done to identify the independent determinants of virological treatment failure. Results: In this study, being male (adjusted odds ratio (AOR) = 1.89, 95% CI: 1.04, 3.47), substance use (AOR = 2.67, 95% CI: 1.40, 4.95), baseline hemoglobin (Hgb) < 12 mg/dl (AOR = 3.22, 95% CI: 1.82, 5.99), poor drug adherence (AOR = 3.84, 95% CI: 1.77, 5.95), restart ART medication (AOR = 2.45, 95% CI: 1.69, 7.35), and opportunistic infection (OI) while on HAART (AOR = 4.73, 95% CI: 1.76, 12.11) were determinants of virological treatment failure. Conclusion: The study revealed that the sex of the patient, history of substance use, baseline Hgb < 12 mg/dl, poor drug adherence, restart after an interruption, and having OI through the follow-up period were determinants of virological failure. Therefore, program implementation should consider gender disparity while men are more prone to virological failure. It is also imperative to implement targeted interventions to improve drug adherence and interruption problems in follow-up care. Moreover, patients with opportunistic infections and restart HAART need special care and attention.

Does the perception of HIV risk among Female sex workers affect HIV prevention behavior? application of the Health Belief Model (HBM).

BACKGROUND: High prevalence of Human Immune virus/Acquired immunodeficiency syndrome (HIV/AIDS) in Female Sex Workers (FSWs) is identified as a bottleneck in fighting against HIV/AIDS. To this end, the international community planned a strategy of 'Ending inequality' and 'Ending the AIDS epidemic' by 2030. This could not be achieved without due attention to FSWs. Thus, this study attempted to assess HIV prevention behavior and associated factors among FSWs in Dima district of Gambella region, Ethiopia by using the Health Belief Model. METHODS: A community-based cross-sectional study was conducted from March to May 2019 among 449 FSWs selected using the snowball sampling technique. Socio-demographic features, knowledge about HIV, attitude toward HIV prevention methods, and Health Belief Model (HBM) constructs (perceived susceptibility to and severity of HIV, perceived barriers, and benefits of performing the recommended HIV prevention methods, self-efficacy, and cues to practice HIV prevention methods) were collected using face to face interview. Data were entered into Epi-data 3.1 and analyzed using SPSS version 23. Bivariable and multivariable binary logistic regression analysis was done to identify the association between dependent and independent variables. P-value < 5% with 95 CI was used as a cutoff point to decide statistical significance of independent variables. RESULTS: In this study, 449 FSWs participated making a response rate of 98.90%. Of these, 64.8% had high HIV prevention behavior. Age (AOR = 1.911, 95% CI: 1.100, 3.320), knowledge of HIV (AOR = 1.632, 95% CI: 1.083, 2.458), attitude towards HIV prevention methods (AOR = 2.335, 95% CI: 1.547, 3.523), perceived barriers (AOR = .627, 95% CI: .423, .930), and self-efficacy (AOR = 1.667, 95% CI: 1.107, 2.511) were significantly associated with high HIV prevention behavior. CONCLUSION: The study identified that about two third of FSWs practiced the recommended HIV prevention methods. Age of respondents, knowledge of HIV, favorable attitude towards the recommended HIV prevention methods, high self-efficacy, and low perceived barrier were associated with high HIV prevention behavior. Therefore, focusing on these factors would be instrumental for improving effectiveness of the ongoing HIV prevention efforts and attaining the 'Sustainable Development Goals of 'Ending inequality' and 'Ending the AIDS epidemic' by 2030.

Prevalence of Hepatitis B Virus Among Pregnant Women on Antenatal Care Follow-Up at Mizan-Tepi University Teaching Hospital and Mizan Health Center, Southwest Ethiopia.

BACKGROUND: Hepatitis B virus(HBV) infection is a global public health problem, even though its prevalence is disproportionately high in low- and middle-income countries. Mother-to-child transmission is a major route of HBV transmission in endemic areas. This study aimed to assess the prevalence of HBV and its determinants among pregnant women attending antenatal care at Mizan-Tepi University Teaching Hospital and Mizan Health Center, Southwest Ethiopia. METHODS: A cross-sectional study was conducted between January 13th 2020 and February 5th 2020 among 370 pregnant women. The sample size was proportionally allocated to each health institution according to the total pregnant women on antenatal care at the respective health institution and a consecutive sampling technique was used to select study participants. Serum hepatitis B surface antigen (HBsAg) was tested using a rapid diagnostic test. Data were analyzed using Statistical Package for Social Sciences (SPSS) software version 22. Multiple logistic regression analysis was done to identify the independent predictors of HBsAg serostatus at p-value <0.05. RESULTS: Three hundred seventy of the total 375 pregnant women participated in the study resulting in a response rate of 98.7%. Twenty-two (5.9%) of the pregnant women screened were found positive for HBsAg (prevalence=5.9%; 95% CI: 3.9-8.80%). History of contact with jaundice patients (AOR=9.87; 95% CI: 2.98-32.65), sharing sharp materials (AOR=3.96; 95% CI: 1.23-11.08) and history of multiple sexual partners (AOR=6.77; 95% CI: 2.44-18.78) were significantly associated with Hepatitis B Virus infection. CONCLUSION: The endemicity of hepatitis B virus seroprevalence is intermediate in the study settings. Factors associated with hepatitis B virus serostatus were behavioral; hence, modification of these factors may help to prevent the infection.

Determinants of Delayed Treatment-Seeking for Childhood Diarrheal Diseases in Southwest Ethiopia: A Case-Control Study.

BACKGROUND: Although there are low cost and effective interventions to prevent and treat diarrhea, it is one of the leading causes of morbidity and mortality among under-five children in developing countries. Deaths from diarrheal diseases are largely due to lack of prompt seeking of medical care. This study aimed to identify determinants of delayed treatment-seeking for diarrheal diseases among under-five children in Southwest Ethiopia. METHODS: Unmatched case-control study was conducted among 324 under-five children paired with their mothers/caregivers from 1st April to 30th May 2019. Cases were under-five children paired with their mothers/caregivers who sought treatment after 24 hours of the onset of signs and symptoms of diarrheal diseases, and controls were under-five children paired their mothers/caregivers who sought treatment within 24 hours of the onset of signs and symptoms of diarrheal diseases. Consecutive sampling was used, and data were collected through interviews and chart reviews. Multivariable binary logistic regression analysis was performed, and variables with a P-value <0.05 were considered statistically significant. RESULTS: A total of 324 (162 cases and 162 controls) under-five children paired with their mothers/caregivers were included in this study. Being rural residents (AOR=1.93, 95% CI: 1.13,3.31), children from households with more than two children (AOR=2.05, 95% CI: 1.15-3.66), preferring traditional healers for the treatment of diarrhea (AOR= 4.78, 95% CI: 1.74,13.12), not having television or radio for the households (AOR=2.05, 95% CI: 1.11-3.66), living in more than 10 km from the nearest health facility (AOR=4.80, 95% CI: 2.61-4.83), and perceiving diarrhea can cure without treatment (AOR=2.11, 95% CI: 1.15-3.87) were significant determinants of delayed treatment-seeking. CONCLUSION: Being rural residents, larger family size, physical inaccessibility of health facilities, not having access to electronic media (television or radio), preferring traditional healers for the treatment of diarrhea, and having the perception that diarrhea can be cured without treatment were determinants of delayed treatment-seeking for diarrheal diseases among under-five children. Thus, multidimensional approaches that can address accessibility of health facilities and improve caregivers' awareness are necessary to encourage prompt treatment-seeking for diarrheal diseases among under-five children.

Predictors of Clinical and Immunological Failure Among Patients on First-Line Antiretroviral Therapy (ART) in Southwest Ethiopia.

BACKGROUND: Global expanded access to antiretroviral therapy has led to a rapid fall in the number of people dying from HIV-related causes. However, the remarkable achievement recorded in reducing morbidity and mortality has been affected due to the occurrence of first-line ART failure. The study was intended to identify predictors of clinical and immunologic failure of first-line ART in southwest Ethiopia. METHODS: A retrospective cohort study was conducted among 737 randomly selected ART patients from 1st January 2010 to 30th June 2016. Trained data collectors collected the data from the patients' follow-up charts and electronic databases. The Kaplan Meier (KM) curve was used to describe the probability of survival time to antiretroviral treatment failure. Variables with a p-value of ≤ 0.05 in a multivariable cox-proportional hazard model were statistically significant predictors of first-line ART failure. RESULTS: Among 737 HIV patients on ART followed retrospectively, 445 (60.4%) were females. During the follow-up period, the incidence rate of treatment failure was 7.3 per 100 person-year observations, and the highest rate was observed during the first 6 to 12 months of ART initiation. Not disclosing HIV status (AHR꞊ 2.04, 95% CI: 1.32-3.16), being bedridden (AHR꞊ 2.01, 95% CI: 1.02-3.98) and low hemoglobin at ART initiation (AHR꞊ 2.02, 95% CI: 1.29-3.13) were associated with an increased hazard rate for first-line ART failure. CONCLUSION: The study showed that predictors of first-line ART treatment failure are modifiable. Therefore, these factors should be addressed during routine care of HIV patients by health care providers to preserve the rapid exhaustion of  first-line medications, improve the quality of life of the patients and reduce HIV/AIDS related deaths.
