Approximately 30% of infections among adults present as icteric hepatitis, and 0.1–0.5% of patients develop fulminant hepatitis. When fulminant hepatitis occurs, the immune response to infected hepatocytes is overwhelming and there is often no evidence of viral replication. Testing for HBsAg may be negative; there is therefore a need for further anti-HBc (IgM) testing.
在成年人急性病毒性肝炎感染病例中,大约30%表现为黄疸型肝炎, 0.1 — 0.5% 发展暴发型肝炎。当暴发型肝炎发生时,被病毒感染的肝细胞发生过度免疫反应,而常常没有病毒复制的证据,HBsAg可以是阴性的,因此,需要查anti-HBc (IgM) .
我补充一点: Anti-HBc (IgM) rises rapidly in patients with acute infection and persists for several weeks to months. 在急性乙型肝炎病毒感染的病人身体内,乙型肝炎病毒核心抗体IgM 迅速上升,持续几个星期到几个月。
黄洋的临床表现、血液中肝炎病毒标志物的动态过程、肝脏酶学检查的动态过程以及肝组织病理切片的特征,均符合暴发型肝炎,因此,黄洋爆发性肝炎的死因不能排除。用黄洋的肝脏标本作乙肝病毒的免疫组化染色和DNA检测就可以得到证明。
