Abstract

Background: There are limited data from sub-Saharan Africa on long-term liver fibrosis changes in HIV- A nd HIV/HBV-infected individuals. Objectives: To assess the effects of ART on liver stiffness measurement (LSM) using transient elastography (TE) in HIV- A nd HIV/HBV-infected Nigerian adults and examine factors associated with fibrosis regression. Methods: We included ART-naive HIV- A nd HIV/HBV-infected adults (≥18 years) enrolled in a prospective, longitudinal study of liver disease between July 2011 and February 2015 at Jos University Teaching Hospital HIV Care and Treatment Centre in Nigeria. Patients initiated ART and had TE at baseline and follow-up (year 3). LSM cutoffs for Metavir scores were 5.9, 7.6 and 9.4 kPa for moderate fibrosis, advanced fibrosis and cirrhosis, respectively. We usedmultivariable regression to identify factors associated with TE (≥1 Metavir) stage decline. Results: A total of 106 HIV- A nd 71 HIV/HBV-infected patients [70.5% female and median age"34 years (IQR=29-42 years)] were studied. Baseline LSM and median LSM decline were significantly higher in HIV/HBV-versus HIV-infected patients; 41% of HIV/HBV-infected patients regressed ≥1 Metavir stage versus 17% of HIV-infected patients (P,0.01); LSM scores at year 3 were not significantly different between HIV- A nd HIV/HBV-infected patients. In multivariable analyses, patients with baseline CD4! T cells≥200 (versus ,200) cells/mm3 and lower BMIs weremore likely to experience LSM stage decline. Conclusions: HBV coinfection does not attenuate LSM declines in HIV-infected patients after ART initiation despite being a risk factor for more advanced liver disease prior to therapy. The inverse association between BMI and TE stage decline needs further investigation.
