Abstract

To date, human herpesvirus type 8 (HHV-8) DNA has been found consistently in all types of Kaposi�¢����s sarcoma (KS). This neoplasm occasionally develops in human immunodeficiency virus (HIV) non-infected patients with variable immunologic abnormalities. Immunologic abnormalities have been documented in cirrhotic patients and are strongly associated with cirrhosis severity. In a previous study, our study group found that the seroprevalence of HHV-8 in patients with moderate or severe cirrhosis was significantly greater than that in healthy controls. It appeared to be associated with cirrhosis severity, sex, and disease etiologies. However, the prevalence of HHV-8 infection in patients with mild cirrhosis has not been described, and it is not clear whether HHV-8 prevalence is associated with hepatitis activity. Our recent study found that patients with mild cirrhosis had higher seropositivity for KSHV antibodies than healthy controls (P=0.0001). Univariate logistic regression analysis revealed that an age�¢���¥55 years (odds ratio [OR] 2.88, P=0.02), hepatitis C virus (HCV) infection (OR 3.42, P=0.01), and hepatitis activity (OR 4.10, P=0.004) were associated with KSHV seropositivity in mild cirrhotic. Stepwise multivariate logistic regression analysis confirmed that age�¢���¥55 years (adjusted OR [aOR] 1.92, P=0.04) and hepatitis activity (aOR 3.55, P=0.005) were independent factors. The rate of hepatitis activity was higher in HCV-infected than in HBV-infected patients (P<0.0001) and in women than in men (P=0.0001). Mild cirrhotic who were seropositive for KSHV or HCV or had hepatitis activity were significantly older (P=0.02, <0.0001, and <0.0001, respectively). Plasma samples from all participants were negative for KSHV DNA. KSHV antibody titers in mild cirrhotics also markedly exceeded those in controls (P<0.0001), as in patients�¢���¥55 years old vs. younger patients (P=0.01), those in patients with vs. without HCV-infection (P=0.0008), and those in patients with vs. without hepatitis activity (P=0.0005). Patients with mild cirrhosis had high KSHV seroprevalence and HCV infection, and, in particular, old age and hepatitis activity were predictors.
