乙型肝炎患者血清中庚肝病毒核酸的检测

目的:了解乙型肝炎患者HGV感染情况,探讨HGV感染与HBV感染的关系.方法:应用巢氏PCR对1104例乙型肝炎患者进行了血清HGV-RNA检测,以251名正常人为对照.结果:共检出血清HGV-RNA阳性者34例,阳性率3.08%.乙型肝炎患者血清HGV-RNA阳性率(3.17%)与正常人群(2.79%)相比无显著差异(P＞0.05).慢性乙肝患者血清HGV-RNA阳性率(4.78%)显著高于急性乙肝患者(0.96%)(P＜0.05).结论:HGV感染可表现为病毒携带状态、亚临床型和不同临床类型,乙型肝炎患者并不比正常人群更易感染HGV,HGV与HBV重叠感染可能与病情发展和慢性化的形成有关.

Detection of Hepatitis G Virus-RNA (HGV-RNA) in Serum of Patients with HBV Hepatitis

Objective To investigate the incidence of HGV infection in patients with HBV hepatitis and any possible adverse effect of the superinfection. Methods Serum HGV-RNA expression was examined with PCR in 1104 patients with HBV hepatitis and 251 controls. Results The positive rate of HGV-RNA in HBV hepatitis patients was not significantly different from that in controls (3.17% vs 2.79%, P>0.05). Among the patients with HBV hepatitis, HGV-RNA positive rate in patients with chronic hepatitis was significantly higher than that in patients with acute hepatitis (4.78% vs 0.96, P<0.05). Conclusion HGV infection might be presented as non-symptomatic carriers or other mild form of hepatitis. The incidence of HGV infection was not especially hihg in HBV hepatitis patients, however, concomittant HGV and HBV infection might predispose to development of chronicity.
