Efficacy and Tolerability of Tenofovir Disoproxil Fumarate Based Regimen as Compared to Zidovudine Based Regimens: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Although tenofovir (TDF)/emtricitabine (FTC)/efavirenz (EFV) and zidovudine (ZDV)/lamivudine (3TC)/efavirenz (EFV) are used as preferred first line regimen, their head-to-head comparison in terms of their efficacy and tolerability was limited. This review aimed to synthesize the best available evidence on the comparative efficacy and tolerability of the two regimens.

Methods

Seven sites and databases in addition to Google search until August 20, 2016, were searched. Only randomized clinical trials conducted on adult population were included in this study. Our primary outcome was viral load suppression while secondary outcomes were death and tolerability. Undetectable viral load is defined as <50 Human Immunodeficiency Virus (HIV) ribonucleic acid (RNA) copies/ml. Joanna Briggs institute meta-analysis of statistics assessment and review instrument (JBI-MAStARI) and critical appraisal and data extraction tool were applied for critical assessment and data extraction, respectively. We performed a random effect meta-analysis to pool the relative risk (RR) for viral load suppression (<50 HIV RNA copies/ml and <400 HIV RNA copies/ml), tolerability, and death.

Result

Data was extracted from four articles, which included a total of 2381 participants. We found superior viral load suppression among tenofovir (TDF) arm compared to zidovudine (ZDV) arm. Tenofovir arm achieves viral load <50 HIV RNA copies/ml (RR = 1.12, 95% confidence interval (CI) [1.04, 1.21], I² = 0%) higher than zidovudine arm. Similarly TDF arm is superior in viral load suppression to <400 HIV RNA copies/ml (RR = 1.19, 95% CI [1.11, 1.27], I² = 0%). Moreover, TDF based regimens were more likely to be tolerated than ZDV based regimens (4 trials, 2381 participants (RR = 1.06, 95% CI [1.02, 1.10], I² = 51%)). However, forest plot of death shows that it was not significant (RR = 0.91, 95% CI [0.51, 1.62]).

Conclusion

The use of TDF/FTC/EFV as first line regimen for naïve HIV-1 infected adult patient showed superior viral load suppression and tolerability as compared to ZDV/3TC/EFV. In order to compare the death outcome of both ZDV/3TC/EFV and TDF/FTC/EFV further research is needed.

Project description:BackgroundIn human immunodeficiency virus (HIV) treatment, tenofovir alafenamide (TAF) is associated with greater increases in all fasting cholesterol subgroups compared with tenofovir disoproxil fumarate (TDF). Because lipid abnormalities may contribute to cardiovascular morbidity and mortality, cardiovascular risk assessment is integral to routine HIV care. This post hoc study evaluates the impact of lipid changes on predicted atherosclerotic cardiovascular disease (ASCVD) risk and statin eligibility in treatment-naive adults living with HIV treated with TAF or TDF.MethodsParticipants (N = 1744) were randomized (1:1) to initiate TAF or TDF, each coformulated with elvitegravir/cobicistat/emtricitabine (studies GS-US-292-0104 and GS-US-292-0111). Eligibility for statin therapy and estimated 10-year ASCVD risk among adults aged 40-79 years treated with TAF or TDF for 96 weeks (W96) were analyzed based on American College of Cardiology/American Heart Association Pooled Cohort Equations. Categorical shifts in 10-year ASCVD risk from <7.5% to ≥7.5% by W96 on TAF versus TDF were calculated.ResultsParticipants initiating TAF versus TDF in the overall study population showed small but significant increases in median fasting lipid parameters at W96, including total cholesterol (191 vs 177 mg/dL; P < .001), low-density lipoprotein ([LDL] 119 vs 112 mg/dL; P < .001), and high-density lipoprotein ([HDL] 51 vs 48 mg/dL; P < .001), respectively. At baseline, 18% and 23% on TAF versus TDF had a 10-year ASCVD risk score ≥7.5%, with mean risk scores low overall for TAF versus TDF at baseline (4.9% vs 5.4%; P = .35) and W96 (6.1% vs 6.2%; P = .04). Increases in ASCVD risk from baseline to W96 were driven by both increasing age and changes in total cholesterol (TC) and HDL cholesterol. At W96, TC/HDL ratios (median) were 3.7 for both groups (P = .69). There was no difference between shifts in categorical risk for TAF versus TDF (9% vs 5%; P = .19). Eligibility for high-intensity statin therapy were similar for TAF versus TDF groups (19% vs 21%; P = .47).ConclusionsLipid changes with TAF as part of coformulated regimens do not substantively affect CVD risk profiles compared with TDF.
