肺炎支原体(MP)是一种介于细菌和病毒间的病原微生物,是小儿呼吸道感染的常见重要病原体之一。MP感染除可引起肺炎外,还可引起肺外多系统的并发症。近年来,关于MP感染并发血小板减少性紫癜的国内外临床报道较多,同时也得出了细胞免疫在其中起了重要作用的结论,但对其具体发病机制尚不清楚,现就MP致血小板减少性紫癜发病机制的研究予以综述。 Mycoplasma pneumoniae (MP), a pathogenic microorganism between bacteria and viruses, is one of the most common pathogens in children with respiratory infections. In addition to MP infection can cause pneumonia, but also can cause multiple system extra-pulmonary complications. In recent years, MP infection complicated with thrombocytopenic purpura clinical reports at home and abroad more, but also come to the conclusion that cellular immunity plays an important role in it, but its specific pathogenesis is not yet clear, is MP platelet Reduce the pathogenesis of purpura to be reviewed.
