[Detection of anti-HAV IgM and anti-HEV IgM in patients with sporadic acute hepatitis in Beijing between 1995-2000].

OBJECTIVE

To investigate the age ranges, liver function lesion and outcomes of sporadic acute hepatitis A and E in Beijing.

METHODS

Enzyme immunoassay(EIA) was used for detection of anti-HAV and anti-HEV immunoglobulin M(IgM). Samples were collected from the patients with sporadic acute viral hepatitis in Beijing between 1995-2000.

RESULTS

The total rate of positive for anti-HAV and anti-HEV was 55.2% (112) in 203 patients with acute hepatitis, 22.2% (45) and 33% (67) were positive separately for anti-HAV and anti-HEV in 112 patients. The duration of anti-HEV IgM was 45-60 days and that of anti-HAV IgM was at least 2-3 months. The patients with acute hepatitis A and hepatitis E all experienced jaundice, a rising of liver enzyme, but not developed to chronic hepatitis or to death.

CONCLUSION

Acute hepatitis A as well as acute hepatitis E takes an important place in sporadic enterically transmitted hepatitis in Beijing.
