总结该院近３年老年病毒性肝炎中戊型肝炎病毒感染占５２．９％，明显高于非老年组的１７．９％，老年戊肝病毒感染的临床类型大部分表现为急性黄疸型肝炎（８８．９％），小部分在慢性肝病基础上急性发病（１１．１％），其病原类型７７．８％为单独戊肝病毒感染，合并其它肝炎病毒感染占２２，２／。老年急性戊型肝炎的临床特点：（１）平均血胆红素水平及重度黄疸发生率均明显高于非老年组（Ｐ＜０．０１）；（２）血清白蛋白降低及球蛋白升高的发生率均明显高于非老年组（Ｐ＜０．０１）；（３）夹杂症多；（４）病死率高为５．７％。
In conclusion, the incidence of hepatitis E virus infection in elderly patients with viral hepatitis in the past three years was 52.9%, significantly higher than that in non-elderly patients (17.9%). Most of the clinical types of hepatitis E virus infection were acute jaundice hepatitis (88.9%). A small proportion of patients were acutely infected (11.1%) on the basis of chronic liver disease. 77.8% of them were infected with HEV alone. Other hepatitis virus infections accounted for 22.2%. The clinical features of acute hepatitis E in the elderly were as follows: (1) The average level of serum bilirubin and severe jaundice were significantly higher than those in the non-elderly group (P <0.01); (2) Serum albumin and globulin were elevated Were significantly higher than those in the non-elderly group (P <0.01); (3) more complications; (4) high mortality rate of 5.7%.
