Statin drugs decrease progression to cirrhosis in HIV/hepatitis C virus coinfected individuals.

ABSTRACT: Chronic HIV/hepatitis C virus (HCV) coinfection carries increased risk of cirrhosis, hepatocellular carcinoma, and death. Due to anti-inflammatory properties, 3-hydroxy-3methylglutaryl coenzyme A (HMG-CoA) inhibitors (statins) may be useful adjunctive therapy to reduce liver disease progression.Clinical information was extracted from the Veterans Affairs HIV and HCV Clinical Case Registries (1999-2010). HIV-related variables included combination antiretroviral therapy era of diagnosis, CD4 cell count, and percentage time with undetectable HIV viral load. Metabolic variables included diabetes, low high-density lipoprotein (HDL), and hypertension. Statin use was measured as percentage time with active prescription (time-updated throughout the follow-up period). Cox proportional hazards analysis was used to determine risk factors for cirrhosis (International Classification of Diseases-9 or aminotransferase-to-platelet ratio index >2) overall and in groups stratified by alanine aminotransferase (ALT) level above and below 40?IU/l.The cohort included 5985 HIV/HCV coinfected veterans. The majority was black race, and the mean age at index date was 45 years. Statin use was significantly protective of cirrhosis for patients with ALT 40?IU/l or less; for every 30% increase in time on statin, there was a 32% decreased risk of developing cirrhosis (hazard ratio 0.68, 95% confidence interval 0.47-0.98). Diabetes and low HDL were significantly associated with cirrhosis in patients with ALT greater than 40?IU/l (hazard ratio 1.15, P?

Project description:BACKGROUND:Hepatitis B virus (HBV) infection is a leading cause of end-stage liver disease (ESLD) and hepatocellular carcinoma (HCC) in HIV. Factors contributing to the high rates of liver complications among HIV/HBV-coinfected individuals remain unknown. SETTING:North American AIDS Cohort Collaboration on Research and Design. METHODS:We performed a retrospective cohort study among HIV/HBV-coinfected patients in 10 US and Canadian cohorts of the North American AIDS Cohort Collaboration on Research and Design that validated ESLD (ascites, spontaneous bacterial peritonitis, variceal hemorrhage, and/or hepatic encephalopathy) and HCC diagnoses from 1996 to 2010. Multivariable Cox regression was used to examine adjusted hazard ratios [aHRs with 95% confidence interval (CIs)] of liver complications (first occurrence of ESLD or HCC) associated with hypothesized determinants and with increasing durations of HIV suppression (?500 copies/mL). RESULTS:Among 3573 HIV/HBV patients with 13,790 person-years of follow-up, 111 liver complications occurred (incidence rate = 8.0 [95% CI: 6.6 to 9.7] events/1000 person-years). Rates of liver complication were increased with non-black/non-Hispanic race [aHR = 1.76 (1.13-2.74)], diabetes mellitus [aHR = 2.07 (1.20-3.57)], lower time-updated CD4 cell count [<200 cells/mm: aHR = 2.59 (1.36-4.91); 201-499 cells/mm: aHR = 1.75 (1.01-3.06) versus ?500 cells/mm], heavy alcohol use [aHR = 1.58 (1.04-2.39)], and higher FIB-4 at start of follow-up [>3.25: aHR = 9.79 (5.73-16.74); 1.45-3.25: aHR = 3.20 (1.87-5.47) versus FIB-4 <1.45]. HIV suppression for ?6 months was associated with lower liver complication rates compared with those with unsuppressed HIV [aHR = 0.56 (0.35-0.91)]. CONCLUSIONS:Non-black/non-Hispanic race, diabetes, lower CD4 cell count, heavy alcohol use, and advanced liver fibrosis were determinants of liver complications among HIV/HBV patients. Sustained HIV suppression should be a focus for HIV/HBV-coinfected patients to reduce the risks of ESLD/HCC.
