Unusual presentation of Thrombotic Thrombocytopenic Purpra in a newly
diagnosed pediatric patient with Systemic Lupus Erythematosus in the
setting of MIS-C
Abstract
The understanding of Coronavirus disease 2019 (COVID-19) immune
dysregulation is evolving. Systemic lupus erythematosus (SLE) is a
multisystem autoimmune disease with alternations in both innate and
adaptive immunity, probably caused by a complex interplay of genetics
and environmental exposure with various triggers. A rare hematological
complication of SLE as well as recently reported in adult with COVID-19
is thrombotic thrombocytopenic purpura (TTP). We report a pediatric case
with features suggestive of multisystem inflammatory syndrome in
children (MIS-C) with coronary artery ectasia, TTP, autoimmune hemolytic
anemia (AIHA) and thrombocytopenia with new onset SLE as well.
