对563例内、外科经输血治疗的住院病人进行了前瞻性的调查,结果发现输血后乙型肝炎病毒感染56例(9.94%),输血后确诊及疑诊的非甲非乙型肝炎(NANBH)34例(6.0%)。NANBH的诊断标准必须SGPT升高至正常值的2倍以上,多次排除甲、乙型肝炎及药物、中毒性肝炎的可能。完全符合这一标准的10例中,单次输血者5例,平均潜伏期41.2天。临床症状一般较轻,2例进行了肝穿刺组织学检查。24例SGPT升高不足正常值2～3倍或持续异常不满3周(包括未及时复查者),今后需进一步观察。
A total of 563 hospitalized patients undergoing transfusion therapy were prospectively investigated. The results showed that 56 (9.94%) patients were infected with hepatitis B virus after transfusion and the number of confirmed and suspected non-A non-B hepatitis after transfusion (NANBH ) 34 cases (6.0%). The diagnostic criteria of NANBH SGPT must be increased to more than 2 times the normal, multiple exclusion of hepatitis A and B, the possibility of toxic hepatitis. Of the 10 patients that fully met this criterion, 5 were single-transfused, with an average incubation period of 41.2 days. Clinical symptoms were generally mild, and liver biopsy histology was performed in 2 cases. 24 cases of SGPT increased less than normal 2 to 3 times or sustained abnormal less than 3 weeks (including those who did not promptly review), the need for further observation in the future.
