Abstract: In hepatitis C virus (HCV) infection, virus load and the risk for HCV-related end-stage liver disease (ESLD) are increased among persons with human immunodeficiency virus (HIV) coinfection. To clarify these relationships, 42 hemophilic patients who developed ESLD and random samples from 164 hemophilic patients with HCV infection alone and 146 with HCV-HIV coinfection were tested for HCV load and genotype. HCV genotype was unrelated to HIV and age. In contrast, HCV load was higher with older age (P(trend)=.0001) and with HIV coinfection (6.2 vs. 5.9 log(10) genome equivalents/mL, P=.0001). During 16 years of follow-up of dually infected patients, ESLD risk was unrelated to HCV load overall (P(trend)=.64) or separately to HCV genotype 1 and genotypes 2 or 3 (P(trend)> or =.70). Irrespective of virus load, incidence of ESLD was marginally increased 2-fold (95% confidence interval, 0.8-5.6) with HCV genotype 1. Understanding the discordance between HCV load and ESLD, despite HIV's link to each of these, may help clarify the pathogenesis of HCV-related disease.
