目的 探讨急性乙型肝炎 (急乙肝 )和慢性乙型肝炎病毒感染急性发作 (慢乙肝急性发作 )的鉴别诊断及预防措施。方法 通过比较急乙肝和慢乙肝急性发作患者的临床资料 ,发现有用的鉴别指标。结果 患者入院时血清中HBV DNA定量已经阴转 ;当ALT降至 4 0 0IU L以下时 ,HBV DNA定量阴转或HBsAg阴转或已经发生HBeAg HBeAb转换 ;均可诊断为急乙肝。结论 上述临床指标有助于正确鉴别急乙肝和慢乙肝急性发作
Objective To explore the differential diagnosis and preventive measures of acute hepatitis B (acute hepatitis B) and chronic hepatitis B virus infection (acute attack of chronic hepatitis B). Methods By comparing the clinical data of patients with acute hepatitis B and chronic hepatitis B, find useful indicators of discrimination. Results The serum HBV DNA quantitation had been overturned when the patient was admitted to the hospital. When the ALT dropped below 400 IU, the HBV DNA negative conversion or HBsAg negative conversion or the HBeAg HBeAb conversion occurred; all of them could be diagnosed as acute hepatitis B. Conclusions The above clinical indexes help to identify the acute attack of acute hepatitis B and chronic hepatitis B correctly
