慢性肝炎是一种常见病。根据国内的资料,乙型肝炎病毒(简称HBV)是慢性肝炎最重要的病因之一。我们与虹桥医院对220例HB_sAg阳性的急性肝炎病人进行2年随访,结果在73例(33.2%)HB_sAg持续阳性的病人中,有35例(15.9%)转为迁延性肝炎,10例(4.5%)转为慢性活动性肝炎和肝硬化。而348例HB_sAg阴性的急性肝炎患者中,仅16例转为迁延性肝炎(4.7%),无1例转为慢性活动性肝炎或肝硬化。近年来的研究认为,急性肝炎转化为慢性肝炎与机体的免疫反应有关,现就这方面的研究
Chronic hepatitis is a common disease. According to the domestic data, hepatitis B virus (referred to as HBV) is one of the most important causes of chronic hepatitis. We and Hongqiao Hospital, 220 cases of HB_sAg-positive acute hepatitis patients were followed up for 2 years, the results of 73 cases (33.2%) HB_sAg positive patients, 35 patients (15.9%) into protracted hepatitis, 10 cases (4.5 %) To chronic active hepatitis and cirrhosis. Of the 348 patients with HBsAg-negative acute hepatitis, only 16 were converted to persistent hepatitis (4.7%) and none to chronic active hepatitis or cirrhosis. In recent years, studies suggest that acute hepatitis into chronic hepatitis and the body’s immune response, now on this aspect of the study
