We investigated epidemiologically the risk factors of hepatitis E in Taiyuan. Of 385 patients with acute viral hepatitis collected, 191(49.61%) were serologically identified to have hepatitis A, 104(27.01%) HB, 34 (8.80%) HE, 20(5.19%) HC and 22(5.72%) unidentified types. The male to female ratio of HE as 6.5∶1. The median age of occurrence in the patients with HE was 38.5 years. One of three pregnant women with HE developed premature labor with fetal wastage. Case contorl study was conducted in 70 patients... We investigated epidemiologically the risk factors of hepatitis E in Taiyuan. Of 385 patients with acute viral hepatitis collected, 191(49.61%) were serologically identified to have hepatitis A, 104(27.01%) HB, 34 (8.80%) HE, 20(5.19%) HC and 22(5.72%) unidentified types. The male to female ratio of HE as 6.5∶1. The median age of occurrence in the patients with HE was 38.5 years. One of three pregnant women with HE developed premature labor with fetal wastage. Case contorl study was conducted in 70 patients with HE and 70 controls. The controls were selected from other subjects with no histories of hepatitis and matched by age and sex. The data were dealed with single factor analysis and conditional logistic regression analysis. The results showed that eating meals in resturants ( OR 2.01, 95% CL 1.28~3.15), contacting with hepatitis case ( OR 6.04, 95% CL 1.24~ 29.29), ingesting dirty drink ( OR 2.16, 95% CL 2.05~2.26) are the major risk factors for HE. 为了解本地区戊型肝炎(HE)流行特征及危险因素,于1994年3~12月对385例急性散发性病毒性肝炎进行血清学分型。结果:甲型肝炎191例(49.61%),乙型肝炎104例(27.01%),丙型肝炎20例(5.19%),HE34例(8.80%),未能分型22例(5.72%)。HE男∶女为6.5∶1,发病平均年龄38.5岁;临床特点:起病急,病程短,预后好;3例HE孕妇中,1例发生死胎。将1993~1994年确诊的70例HE病人作病例组,按性别年龄配比选70例非肝炎病人作对照,进行配比病例对照研究,经单因素和多因素条件logistic回归分析表明:在外用餐史(OR2.01,95%CL1.28~3.15),肝炎接触史(OR6.04,95%CL1.24~29.29),不洁饮食史(OR2.16,95%CL2.05~2.26),3个因素为本病的主要危险因素。 \ A seroepidemiological study was carried out in 166 patients from Liuzhou city of GuangxiThe results showed that the acute infective markers of hepatitis A(HA),hepatitis B(HB),hepatitis C(HC),hepatitis E(HE),hepatitis G(HG) and unidentified types (Non AG hepatitis) were 482%,5120%,542%,1386%,1164%and 1742% in the cases of sporadic acute viral hepatits,respectively.The analysis of risk factors showed that higher history of liver disease,multitransfusions and surgical history of operation were found... \ A seroepidemiological study was carried out in 166 patients from Liuzhou city of GuangxiThe results showed that the acute infective markers of hepatitis A(HA),hepatitis B(HB),hepatitis C(HC),hepatitis E(HE),hepatitis G(HG) and unidentified types (Non AG hepatitis) were 482%,5120%,542%,1386%,1164%and 1742% in the cases of sporadic acute viral hepatits,respectively.The analysis of risk factors showed that higher history of liver disease,multitransfusions and surgical history of operation were found in HB,HC and HG patients.It is suggested that the HBV occupies an important place in sporadic acute viral hepatitis in Guangxi,and the main route of transmission is an iatrogenic transmission. 对广西166例住院急性散发性病毒性肝炎病例进行血清流行病学调查研究,结果表明,甲型、乙型、丙型、戊型、庚型肝炎急性期感染指标检出率分别为4.82%、51.20%、5.42%、13.86%和11.64%,未分型病例占17.42%。危险性因素分析表明,乙肝、丙肝和庚肝病人中有较高的肝病史、输血史和手术史。认为乙肝在急性散发性病毒性肝炎中占重要地位。医源性传播是主要传播途径。 To investigate the serological type and epi-demiological characteristics of acute viral hepatitis in Xi'an city. Methods: A total number of 459 hospitalized patients who were clinically diagnosed as acute viral hepatitis,admitted from Oct 1993 to March 1996 in five hospitals, were studied using ELISA in this paper. Results; Among them:HA (hepatitis A)accounted for 59. 26% ,HB ( hepatitis B )11. 98% , HC (hepatitis C) 6. 10% ,HD(hepatitis D) 3. 70% ,HE(hep-atitis E) 4. 36% and HG(Hepatitis G) 3. 70% ,including...

Conclu sion: It shows that HAV and HBV are the major causes of viral hepatitis in Xi'an. Except HE,male patients predominate over female patients in all other types of hepatitis,especially in HD and HG. HA cases predominantly happen in autumn and winter,while other types of viral hepatitis have no significant seasonal distribution. 研究西安市急性散发性病毒性肝炎的分布情况.方法:以1993-10至1996-03连续收集的西安市散发性急性病毒性肝炎病例459例作为研究对象,进行血清学分型与流行病学研究.结果:甲肝(HA)占59.26%,乙肝(HB)占11.98%,丙肝(HC)占 6.10%,丁肝(HD)占3.70%,戊肝(HE)占4.36%,庚肝(HG)占3.70%,未能分型者占11.90%,结论;这表明在西安市急性病毒性肝炎中,HA为主要类型.此外,HA的发病年龄较其他各型肝炎为低,多发于秋冬季节,而其余各型肝炎则无明显的季节性.除HE外,各型肝炎均为男性多于女性.各型肝炎病毒的感染形式可以是单一型.亦可以是混合型或重叠型.
