High plasma efavirenz level and CYP2B6*6 are associated with efavirenz-based HAART-induced liver injury in the treatment of naïve HIV patients from Ethiopia: a prospective cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The objective of this study was to assess the incidence, timing and identify pharmacogenetic, efavirenz (EFV) pharmacokinetic and biochemical predictors of EFV-based antiretroviral therapy (ART) drug-induced liver injury (DILI). ART-naïve HIV patients (n = 285) were prospectively enrolled. Pretreatment laboratory evaluations included hepatitis B surface antigen and C antibody, CD4 count and viral load. Liver tests were done at baseline, 1st, 2nd, 4th, 8th, 12th, 24th and 48th weeks during ART. Plasma EFV and 8-hydroxyefvairenz concentration was determined at week 4 using liquid chromatography-mass spectrometry. CYP2B6, CYP3A5, ABCB1 3435C/T and UGT2B7*2 genotyping was done using Taqman genotyping assay. Data were analyzed using survival analysis and Cox proportional hazards model. The incidence of DILI was 15.7% or 27.9 per 100 person-years and that of severe injury was 3.4% or 6.13 per 100 person-years. The median time for the development of DILI and severe injury was 2 and 4 weeks after initiation of ART, respectively. There was significant association of DILI with lower baseline platelet, albumin, log plasma viral load and CD4 count (P = 0.031, 0.037, 0.06 and 0.019, respectively). Elevated baseline alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, plasma EFV level and CYP2B6*6 were good predictors for the development of DILI (P = 0.03, 0.01, 0.016, 0.017 and 0.04, respectively). We report for the first time CYP2B6*6 as a putative genetic marker and high plasma EFV concentration as intermediate biomarker for vulnerability to EFV-induced liver injury in HIV patients. CYP2B6 genotyping and/or regular monitoring of EFV and lever enzymes level during early therapy is advised for early diagnosis and management of DILI.
