Abstract

Acute COVID-19 infection typically results in mild disease in children, but can lead to several immune manifestations. One such severe manifestation is immune-mediated thrombotic thrombocytopenia (iTTP). It is exceedingly rare in children, and only a few cases have been reported worldwide. We report a case of severe iTTP in a 17-year-old girl. She was positive for COVID-19 infection by reverse-transcription polymerase chain reaction at presentation and had received a Covaxin injection two weeks earlier. She responded to therapeutic plasma exchange, corticosteroids, and rituximab. Early recognition of this complication and prompt initiation of therapeutic plasma exchange and corticosteroids is paramount to achieving a good outcome in this rare, life-threatening complication.

一名少女患上与 COVID-19 相关的、危及生命的免疫介导型血栓性血小板减少性紫癜
儿童急性感染 COVID-19 通常病情较轻,但可导致多种免疫表现。其中一种严重的表现是免疫介导的血栓性血小板减少症(iTTP)。这种疾病在儿童中极为罕见,全世界仅有几例报道。我们报告了一例 17 岁女孩的重症 iTTP 病例。就诊时,她通过反转录聚合酶链反应发现 COVID-19 感染阳性,两周前曾注射过可威辛。她对治疗性血浆置换、皮质类固醇激素和利妥昔单抗均有反应。要想在这种罕见的、危及生命的并发症中获得良好的治疗效果,及早发现这种并发症并及时启动治疗性血浆置换和皮质类固醇治疗至关重要。
