Abstract

To investigate the association between diabetes and HCV infection in persons living with HIV and to determine the impact of diabetes on the occurrence of serious liver events (SLEs) and liver-related deaths (LRDs) among HIV/HCV-co-infected patients. Patients were included if they had at least one follow-up visit. In a cross-sectional analysis among all HIV patients, we have investigated the association between diabetes and HCV infection. A further longitudinal analysis was performed in the population of HIV/HCV-co-infected free from SLE with FIB-4 index <3.25 at baseline, using the following endpoints: (A) first event between SLE and LRD; (B) liver fibrosis progression defined as the first of two consecutive FIB-4 > 3.25; (C) first event between SLE, LRD, and liver fibrosis progression. Data from 15,571 HIV patients were analyzed: 2944 (18.9%) were HCV-Ab positive, and 739 (4.7%) presented a diagnosis of diabetes at their last follow-up. Among HIV/HCV-co-infected population, 107 patients had a diagnosis of diabetes. Viremic HCV-co-infected patients had 3-fold risk of diabetes onset than HCV-uninfected patients. On HIV/HCV-co-infected population, 85 SLEs/LRDs occurred over 20,410 person-years of follow-up (PYFU), for an incidence rate of 4.2/1000 PYFU (95%CI 3.4–5.2). Diabetic patients had 3-fold risk of pooled SLE and LRD than patients without diabetes. Furthermore, viremic HCV infection was independently associated with a higher risk of SLE/LRD (aIRR 3.35 [95%CI 1.14–9.83]). In HIV-infected patients, viremic HCV co-infection is a strong predictor of diabetes. Among HIV/HCV-co-infected population, diabetic patients showed an increased risk of SLE/LRD compared with those without diabetes. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
