[The detection and significance of HBV-DNA in serum and liver of advanced schistosomiasis patients].
摘要
Hepatitis B virus deoxyribonucleic acid (HBV-DNA) and surface antigen (HBsAg) in the serum and liver specimens from 31 patients with advanced schistosomiasis were investigated. The patients have been followed up for six years. The presence of HBsAg and HBcAb in serum among patients with advanced schistosomiasis were significantly more frequent than that in the control group (P < 0.05), but the prevalence of HBV-DNA and HBeAg in the patients were not significantly different from that in the controls (P > 0.05). The positive rate of HBV-DNA and HBsAg in liver was 19.4% and 48.4% respectively, which were greater than that in serum. The presence of HBV-DNA in patients with advanced schistosomiasis was associated with high mortality and the cause of death was either hepatic failure or hepatocellular carcinoma. The results suggest that it is important to detect HBV-DNA both in surum and liver. Antiviral therapy for patients with advanced schistosomiasis who had detectable HBV-DNA may improve the prognosis.
