ABSTRACT
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.

BACKGROUND: Measuring portal vein diameter (PVD) is a feasible method of detecting portal vein hypertension, which is a primary and fatal complication of chronic liver disease (CLD) and is usually diagnosed very late. However, there is a paucity of morphometric information on portal vein diameter in the Ethiopian population. Hence, it is important to determine the portal vein diameter among adults with and without chronic liver disease. PURPOSE: The study aimed to identify how PVD is affected by age, sex, and anthropometric measurements in patients with and without CLD. METHODS: A cross-sectional study was conducted among 220 participants (110 CLD patients and 110 controls) who have visited the radiology unit at selected Hospitals. Patients with CLD were selected consecutively as they present while controls were selected by a systematic sampling technique. A structured questionnaire was used to collect the data. Correlation and independent t-test were used to assess the relations. A statistically significant association was declared at P-value <0.05. RESULTS: Mean portal vein diameter for CLD patients was 17.03±1.97 mm with a range of 12.8-20.8mm and 10.79±1.27mm with a range of 7.70-13.25mm for the control group. Age, weight, and body mass index had a positive correlation with portal vein diameter in both groups. The mean portal vein diameter increased by 21.34% during deep inspiration in the control group. CONCLUSION: The mean portal vein diameter among patients with CLD was higher than that of the control group. A significant gender-based difference was recorded in the portal vein diameter of the control group only. Ultrasonography is a non-invasive, readily available diagnostic tool for portal vein pathology. RECOMMENDATION: It is recommended for clinicians to take into consideration age, sex and anthropometric measurements while measuring PVD.
