Prevalence of HIV drug resistance among patients experiencing first-line treatment failure in Ethiopia: A systematic review and meta-analysis
Abstract
Background
The emergence of human immunodefiency virus (HIV) drug resistance presents a substantial challenge. Alternatives for effective treatment regimens are limited, and treatment strategies are complicated. Although a number of primary studies have been performed on HIV drug resistance in Ethiopia, individual study often lacks the statistical strength to draw conclusion. Therefore, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of HIV1 drug resistance among patients experiencing first-line treatment failure in Ethiopia.
Methods
Primary studies were searched from PubMed, SCOPUS, Embase, Google Scholar and online libraries. Studies identified through the search strategies were screened by titles and abstracts. Included studies were evaluated for risk of bias using the Joanna Briggs Institute (JBI) checklist. Data were extracted, and the pooled prevalence of HIV drug resistance was computed using STATA 17 software. Subgroup analysis and meta-regression were performed to identify heterogeneity. Publication bias was checked visually and statistically. Narrative synthesis was performed to describe study characteristics and findings; and forest plots were used to visually represent effect sizes and confidence intervals from individual studies to present and synthesize the results.
Results
A total of 10 studies with 1233 participants were included. The pooled prevalence rate of HIV drug resistance in patients with first line treatment failure was 73% (95% CI: 67–78%, I2 = 68.1%, P < 0.001). It was increased over time: 67.2% from 2008 to 2015 (I2 = 47.8%, P = 0.088) and 77.7% from 2016 to 2020 (I2 = 60.4%, P = 0.056). The prevalence rate was 82.6% (I2 = 0.0%; P = 0.532) in Southern Nations Nationalities People, 70.15% (I2 = 41.5%, P = 0.19) in Oromia, and 53% (I2 = 50.7%, P = 0.54) in Amhara regions.
Conclusions
The prevalence rate of HIV drug resistance in Ethiopia is high. This alarms health care workers, programmers and decision makers to consider ways of controlling the emergence of HIV drug resistance and the spread of drug-resistant strains. Timely monitoring of treatment failures, HIV drug resistance testing and switching on appropriate regimen classes are crucial for better treatment outcomes. There was high HIV drug resistance among children but with a high heterogeneity indicating the need for more primary studies.
