肝炎相关性再生障碍性贫血(hepatitis-associated aplastic anemia,HAA)是指在肝炎发生后的再生障碍性贫血(AA)。该病发病急骤,病情进展快,死亡率高。引起肝炎的病因尚不明确,我国为病毒性肝炎大国,国内报道的HAA也以病毒性肝炎居多。而血清学病毒标志物阴性的HAA研究较少,为提高该病认识,我们对近年来收治的血清学病毒标志物阴性的HAA进行临床分析,现报道如下。 Hepatitis-associated aplastic anemia (HAA) refers to aplastic anemia (AA) after hepatitis occurs. The disease is abrupt, rapid progression, high mortality.

To improve the understanding of the disease, we analyzed the HAA negative serology markers in recent years and are reported as follows.
