Background: Hepatitis C virus (HCV) infection is implicated in an increasing number of liver transplantations, hospitalizations and healthcare costs. Aims: We present an updated assessment of comorbidities associated with HCV in comparison to the general US population. Methods: Cross-sectional retrospective review of data from 800 patients with HCV evaluated between January 1998 and November 2007. Patient data were prospectively collected using a standardized questionnaire completed at the first encounter and was compared with general US epidemiological data. Odds ratios and 95% confidence intervals (CI) are reported. Results: HCV conferred a 44% (CI 1.16-1.78) and 25% (CI 1.01-1.54) increased risk of diabetes (12.5 vs. 7.3-8.4%; P=0.001) and obesity (23.9 vs. 19.8-33.1%; P=0.041), respectively, compared with the US population. Human immunodeficiency virus (HIV) (5.3 vs. 0.3%; P<0.001) and end-stage renal disease (ESRD) (4.5 vs. 0.2%; P<0.001) were 16- and 13-fold more prevalent in HCV. Interestingly, HCV bestowed 90% decreased odds (CI 0.09-0.15) for hyperlipidaemia (12.3 vs. 53.2-56.1%; P<0.001). The HCV population had a higher prevalence of significant alcohol consumption (41.5 vs. 4.7%; P<0.001), current smoking (57.7 vs. 18.8-20.8%; P<0.001), drug use (46.8 vs. 14.6-15.6%; P<0.001), incarceration (6.6 vs. 2.7%; P<0.001) and tattoos (20.3 vs. 14%; P=0.011), as well as chronic fatigue (44.6 vs. 11.3-19%; P<0.001) and depression (29.3 vs. 5.0-10.3%; P<0.001). Conclusion: HCV poses an increasing healthcare burden associated with increased prevalence of diabetes, obesity, HIV, ESRD, maladaptive lifestyle habits and poor quality of life. Practitioners should be cognizant of these trends in order to appropriately manage these comorbidities.
