ABSTRACT
226 cases of virus hepatitis(VH)that were from 14 prefectures of Yunnan Province were detected for their sera's infectious and/or immunologic marks of HAV,HBV,HDV,EBV and CMV.82 cases from among them were taken for liver biopsy,and the specimens were ob- served by light microscopy,electron microscopy and immunohistochemical method.The co- incidence rate of pathologic and clinic diagnosis was 65.9%.And HBV was an essential etiogenic organism(70.8%).Hepatitis B occurred commonly and hiddenly.HA,HB,HD and HNANB were scattered over the province.It was also found that 25% of cases had com- pound or superimposed infections of 2 to 3 kinds of viruses.
ABSTRACT
By examining the etiologic serology of 241 cases of hepatitis and the histochemistry of 104 liver biopsies of hepatitis, We have found that the infected persons or infectors who have combined infection with 2-4 viruses are 83 cases (34.4%), with ten types of etiological com- binations. The middle-aged and aged patients possess 38 cases (62.3%) among the patients of superimposed infectors (SI) . The pathological findings of the liver of 48.5% are more se- rious than clinical diagnosis. Compared with simple hepatits A (HA), hapatitis B (HB) and combined infection (CI), SI requires longer duration for treatment and get worse cura- tive effects. It is definitely necessary to treat and isolate the hepatitis patients who have differ- ent etiologies in order to prevent the cross infections.
