The primary mechanism involved is the occurrence of microthrombi due to deficient activity of ADAMTS13 (A Disintegrin And Metalloprotease with ThromboSpondin type 1 repeats, member 13). The most common types of TMA in children are Shiga toxin-producing <em>Escherichia coli</em>-associated hemolytic uremic syndrome (STEC-HUS) followed by complement-mediated (CM) TMA, <em>Streptococcus pneumoniae</em>-associated hemolytic uremic syndrome (Sp-HUS) and hereditary thrombotic thrombocytopenic purpura (hTTP) and other rare causes. Since the outcomes are dismal if appropriate treatment is not promptly initiated, there is a need to have a high clinical suspicion. Additionally, urgently performing ADAMTS13 functional activity and autoantibody levels can help differentiate hTTP, immune thrombotic thrombocytopenic purpura (iTTP), and CM-TMA. The etiological differentiation is crucial as eculizumab is a specific therapy with exceedingly good results in CM-TMA. While plasma exchanges are required for iTTP, besides corticosteroids and/or rituximab, plasma infusions suffice for hTTP. This review focuses on the commonly encountered congenital and acquired types of TMA in children and their varied presentations while briefly touching upon the rarer disorders causing TMA.</p></div>","PeriodicalId":101004,"journal":{"name":"Pediatric Hematology Oncology Journal","volume":"9 1","pages":"Pages 45-53"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2468124524000056/pdfft?md5=4dba7eadeeb54ab07d37de20d02f9f1f&pid=1-s2.0-S2468124524000056-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140123118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to relative rarity and resemblance to other common disorders, the diagnosis is often delayed. Apart from having symptoms related to anemia and chronic hemolysis, most of these patients suffer from complications of iron overload even if not transfusion dependent.

With easier accessibility and widespread availability of genetic testing, it is possible to make molecular diagnoses for most cases. The diagnosis can be accelerated by targeted next-generation sequencing. There's no unifying theory explaining the pathogenesis behind the disease causation. In-depth understanding at the cellular level has clarified the multifactorial pathologic process.
