摘要
对９４例重型病毒性肝炎进行了病毒标志的研究，并分析了几种影响重型肝炎预后的因素。结果发现：单纯ＨＢｖ感染４２例（４４．７％）；混合感染共５０例（５３．２％），其中ＨＢＶ与ＨＣＶｌ９例（２０．２％）．ＨＢＶ与ＮＤＶ１３例（１３．８％），ＨＢＶ与ＨＣＶ、ＨＤＶＩ０例（１０．６％）ＨＡＶ与ＫＢＶ３例（３．２％），ＨＡＶ与ＨＢＵ、ＨＣＶ３例（３．２％）ＨＡＶ与ＨＢｖ、ＨＤＶＩ例（１．１％）．ＮＡＶ与ＨＢＶ、ＨＣＶ、ＨＤＶ１例（１．１％）；病毒标志均阴性者２例（２．１％）。ＨＢＶ、ＨＣＶ和ＨＤＶ混合感染者病情重，病死率高。血清总胆红素越高，凝血酶原活性越低，其病死率越高；有并发症者的预后差，而ＡＭＰ升高者的预后较好；重肝的预后可能与年龄、性别无关。
erum Samples from 94 patients with
severe viral hepatitis were tested for IgM anti-HAV,,HBV markers,
anti-HCVand HDV markers. And the factors relating to prognosis were
analysed. The results showed that 42(44.7%)cases werecaused by HBU
infection alone,50(53.2%)cases were caused by various multiple
infeetion and two(2.1%)cases were notidentified Among these
cases.19(20.2%)cases were HBV and HCV coinfection,13(13.8%)cases were
HBv and HDVcoinfection,10(10.6%)cases were multiple infection of HCU,
and HDV,3(3.2%)cases were HAV and HBU coin-fection 3(3.2%)cases were
multiple infection of HAV.HBV and HCV,one case(1.1%)was multiple
infection of HAV、HBV and HDV ,one case(1.1%)was multiple infection
of HAV 、HBU、HCV and HDV The patients caused by various mul-tiple
infection of HBV、HCV and HDV were more critical and usually
carried higher mortality. There were higher mortalityamonf patients
with higher levels of total serum bilirubin and lower levels of
prothrombin activity. The outcome of the pa-
