在随访的185例急性病毒性肝炎病人中,乙型肝炎的HBsAg阳性率为76.1％,高于慢性乙肝(54.4％)和甲、乙型肝炎合并感染者(53.8％)。发病初期HBsAg滴度低者在发病后1个月内降低或消失,持续时间不超过3个月,恢复期抗-HBs阳转;高者持续阳性9个月以上,不发生抗体阳转。据此可作出预后的早期判断。抗-HBcIgM阳性、NBsAg阴性者抗-HBs阳转率(42.9％)高于HBsAg阳性者(11.3％)。绝大多数病人(91.7％)的抗体阳转发生在病后2个月内。
Of the 185 patients with acute viral hepatitis who were followed up, the positive rate of HBsAg in hepatitis B was 76.1%, higher than that in patients with chronic hepatitis B (54.4%) and those with hepatitis A and C (53.8%). In the early stage of onset, the low HBsAg titer decreased or disappeared within 1 month after the onset, lasting for no more than 3 months, and the anti-HBs positive recovery in the recovery period; the positive persisted for more than 9 months without any antibody positive conversion. Based on this can make an early prognosis. Anti-HBcIgM positive, NBsAg negative anti-HBs positive rate (42.9%) than HBsAg positive (11.3%). The majority of patients (91.7%) had positive antibody positive within 2 months of illness.
