The purpose of this study was to investigate the potential increased risk for dementia in HCV-infected patients. Methods: A population-based cohort study based on the Taiwan National Health Insurance Research Database was conducted. From all potential participants aged 50?years or more, a total of 58?570 matched (1:1) pairs of HCV-infected patients and non-HCV-infected patients were included. Each subject was individually tracked from 1997 to 2009 to identify incident cases of dementia (onset in 1999 or later). Cox proportional hazards regressions were employed to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between HCV infection and dementia. Results: There were 2989 dementia cases from the HCV-infected cohort during the follow-up period of 533?861.1 person-years; the overall incidence rates of dementia differed from the non-HCV cohort (56.0 vs. 47.7 cases per 10?000 person-years, P?0.05). The adjusted HR for dementia was 1.36 (95% CI 1.27-1.42) for HCV-infected patients after adjusting for alcohol-related disease, liver cirrhosis, hepatic encephalopathy and hepatocellular carcinoma. Conclusions: HCV infection may increase the risk for dementia. Further mechanistic research is needed. ? 2013 EAN. |
