Spontaneous relapse in patients with inactive chronic hepatitis B virus infection

Abstract

Background: Chronic hepatitis B virus infection (HBV) may reactivate during the course of the disease and is called spontaneous relapse. The purpose of this study was to evaluate the incidence of relapse of hepatitis in subjects with inactive HBV carriers. Methods: This follow-up study was performed on 785 patients with inactive HBV carriers that were followed-up at six month intervals. The presence of serum HBsAg and anti-HBe, without HBeAg, HBV DNA levels 0.05). The development of relapse in males was higher than females (hazard ratio 2.53, 95% CI 1.2-5.6, p=0.021), but age ≥30 or < 30 years did not have effect (hazard ratio1.21, 95% CI 0.62-2.36, p=0.58). Conclusions: The results show that spontaneous relapse of hepatitis may develop during the course of chronic HBV infection. We suggest that all patients with chronic hepatitis B, regardless of their age, be examined for the possibility of relapse.
