Resum:	Background: Cigarette smoking has been associated with liver fibrosis in the setting of hepatitis C virus (HCV) infection but has not been studied among people with HIV (PWH) who consume alcohol. Methods: This is a cross-sectional study of PWH with heavy drinking and daily smoking in St. Petersburg, Russia. The primary independent variable was past 30-day cigarettes per day (cpd), and the secondary independent variable was pack-years at study entry. Advanced liver fibrosis was defined as FIB-4 > 3. 25. Analyses were adjusted for gender, body mass index (BMI), past 30-day number of heavy drinking days, HCV and CD4 count. Results: Participants (n = 400) were two-thirds male (67. 3%), young (median age 38 years), lean (median BMI 22), HCV antibody positive (84. 5%) and not severely immune suppressed (median CD4 count 351). The median number of past-month cpd was 20 (IQR: 15-25), and the median pack-years was 24 (IQR: 17-31. 8). The prevalence of advanced liver fibrosis was 11. 3% (45/400). In the adjusted logistic regression analyses, we did not observe a significant association between cpd [middle (10. 1-20 cigarettes) vs. lowest (5-10 cigarettes) category (adjusted odds ratio [aOR] (95% confidence interval [CI]): 1. 06 (0. 40-2. 83), highest (>20. 0 cigarettes) vs. lowest category aOR (95% CI): 0. 65 (0. 21-1. 99), global p -value = 0. 62]. The secondary analysis with pack-years yielded similar results [middle (20. 1-30 pack-years) vs. lowest category (≤20 pack-years) aOR (95% CI): 0. 81 (0. 33-1. 99), highest category (>30 pack-years) vs. lowest category aOR (95% CI): 0. 91 (0. 38-2. 19); global p -value = 0. 58]. Conclusions: In this Russian cohort of PWH, we did not detect an association between recent cigarette use or mean pack-years and advanced liver fibrosis.
