Abstract:
A toddler with an unbalanced diet and gastrointestinal bleeding by juvenile polyp developed an aplastic crisis due to the human parvovirus B19 (HPVB19). Although he exhibited microcytic anemia without iron deficiency in the acute phase of HPVB19 infection, he presented with iron deficiency anemia (IDA) in the chronic phase. IDA results in erythroblast hyperplasia and shortened red blood cell lifespan as like congenital hemolytic diseases, which may lead to an aplastic crisis during HPVB19 infection. It should be noted that iron deficiency is often masked, and microcytic anemia may be a clue for IDA.
摘要:
由于人细小病毒B19(HPVB19),一个饮食不均衡且幼年息肉胃肠道出血的幼儿出现了再生障碍性危机。尽管他在HPVB19感染的急性期表现出没有缺铁的小细胞性贫血,他在慢性期出现缺铁性贫血(IDA)。IDA导致红细胞增生和红细胞寿命缩短,就像先天性溶血性疾病一样,这可能导致HPVB19感染期间的再生障碍性危机。应该注意的是,缺铁通常被掩盖,小细胞性贫血可能是IDA的线索。
