360. Advanced Liver Disease in HIV/Hepatitis B Coinfected Patients: Associated with Race, Age, and Comorbidities

Background Hepatitis B virus (HBV) coinfection is common in people with HIV. Compared with HBV mono-infected individuals, those that are HIV/HBV coinfected show evidence of more rapid progression to advanced liver disease (ALD) and increased mortality rate. In this study, we identified characteristics in an HIV/HBV cohort associated with ALD. Methods We retrospectively examined an HIV/HBV coinfected cohort to determine the prevalence of ALD and its correlation with selected variables. Data were drawn from HIV and HBsAg+ patients at three HIV clinics in Houston, Dallas, and San Antonio, Texas. Those without chronic HBV were excluded. ALD was defined as cirrhosis, decompensation, and/or hepatocellular carcinoma, as determined by imaging. Variables included demographics, HIV risk factors, comorbidities, HBsAg loss, HepBeAg, CD4+ count, HBV DNA, and HIV RNA viral load. Bivariate analysis was performed using chi-square and student t-test as appropriate; a logistic regression model was used to identify independent associations among significant variables (STATA). Results Within those with HIV/HBV coinfection (n = 501), 89 (18%) met the criteria for ALD (92% male, 47% Black, 33% White, 16% Hispanic, 73% >40 years old). Amongst these (n = 89), significant differences were observed with race (P = 0.039), age (P = 0.001), patients identified as MSM/Bisexuals (P = 0.047), diabetes mellitus (DM) (P = 0.01) and hepatitis C virus (HCV) coinfection (P ≤ 0.001). Compared with Whites, Blacks are less likely to have ALD (95% CI 0.27, 0.79, P = 0.004), and those age 40–49 (95% CI 1.28, 10.92, P = 0.016) and >50 (95% CI 1.63, 15.54, P = 0.005) were more likely. The multivariate logistic regression analysis showed patients that are White race, age >50, have DM, and those with HCV coinfection had increased risk for ALD (Table 1). No differences were seen with gender, insurance, alcohol use, HBsAg loss, HepBeAg status or baseline CD4+ count, HBV DNA, HIV RNA, and AIDS. Conclusion Increased monitoring for the presence of ADL should be conducted in HIV/HBV coinfection. Particular attention and surveillance should be paid to those with the following risk factors: Whites, elder age (>50), and comorbidities of DM and HCV. These should be taken into consideration when approaching the development and treatment of ADL in HIV/HBV patients. Disclosures All authors: No reported disclosures.
