Background:
The aim of this meta-analysis was to synthesize the available evidence from the literature on the efficacy and safety of integrase inhibitor-based two drug regimens compared to triple drug regimens in virosuppressed people living with HIV (PLWH) in a long-term follow-up (at 96 weeks).
Materials And Methods:
A systematic review and meta-analysis were conducted to evaluate the efficacy, safety, and adverse drug reactions leading to discontinuation of two drug regimens compared to triple drug regimens in virosuppressed PLWH patients at 96 weeks of follow-up. We searched MEDLINE, Google Scholar, and the Cochrane Library up to March 15, 2024, and studies were selected for eligibility based on predefined criteria. Data were extracted independently by two reviewers, and risk ratios (RRs) were calculated as the measure of association between therapy and incidence of events.
Results:
Six studies were included in the analysis, both clinical trials and observational studies. The two drug regimens included cabotegravir/rilpivirine, dolutegravir/lamivudine, and dolutegravir/rilpivirine. No significant differences were observed in treatment failure (RR, 0.77; 95% confidence interval [CI], 0.53-1.13; P=0.182), virological failure (RR, 0.79; 95% CI, 0.48-1.29; P=0.341), adverse drug reactions leading to discontinuation (RR, 1.74; 95% CI, 0.73-4.17; P=0.215), or appearance of mutation (RR, 2.48; 95% CI, 0.33-18.68; P=0.379) between two drug regimen and triple drug regimen groups at 96 weeks of follow up.
Conclusion:
The meta-analysis provide an overview of the available evidence and supports the use of two drug regimens as an option for simplifying treatment and improving clinical outcomes in virosuppressed PLWH.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
