Abstract: OBJECTIVES: To examine the association between hepatitis C virus (HCV) infection, cardiovascular risk factors and cerebro-cardiovascular (CCV) disease. METHODS: The source of data was the Egypt Health Issues Survey conducted in 2015. Participants were 11 256 individuals with complete HCV testing, age 25-59 years. Data on demographics, cardiovascular risk factors, CCV disease (myocardial infarction and/or cerebral stroke) and HCV infection were retrieved. Descriptive, bivariate, multivariable logistic regression and sensitivity analyses were performed to determine the independent association of past HCV exposure or chronic infection with diabetes, hypertension and CCV disease. RESULTS: 3.9% of participants were antibody positive/RNA negative and considered to have past HCV exposure; 7.9% had detectable HCV-RNA and were considered to have chronic infection. Participants with negative antibodies and no history of liver disease (n = 9928) were the control group. In addition to the previously known risk factors, multivariable analyses revealed that diabetes was independently associated with past HCV exposure (OR = 1.71, 95% CI: 1.27-2.32) and HCV chronic infection (OR = 1.56, 95% CI: 1.23-1.97), whereas CCV disease was independently associated with past exposure (OR = 2.69, 95% CI: 1.62-4.46) and not with chronic infection. No evidence of an association between hypertension and either HCV status was found. CONCLUSION: The association of both past HCV exposure and chronic infection with diabetes and that of past HCV exposure with CCV disease may suggest targeting HCV-positive reactors for preventive and curative programmes addressing extrahepatic complications. © 2018 John Wiley & Sons Ltd.
