ABSTRACT
BACKGROUND:
Thrombotic microangiopathy (TMA) includes hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). This study examined the epidemiological characteristics of pediatric patients with TMA classified according to etiology.METHODS:
The survey evaluated 258 Japanese pediatric patients diagnosed with TMA between 2012 and 2015.RESULTS:
The primary diseases responsible for TMA were categorized as TTP (15 cases), Shiga toxin-producing Escherichia coli-associated HUS (STEC-HUS) (166 cases), atypical HUS (aHUS) (40 cases), and secondary TMA (27 cases). The remaining 10 cases were unable to be classified to one of the four categories of the primary disease. Renal replacement therapy was required in the acute phase in 103 patients with TMA, including 65 with STEC-HUS, 22 with aHUS, two with TTP, 10 with secondary TMA, and four unclassified cases. The last observational findings were normal renal function in 95 patients and chronic kidney disease (CKD) stage 1 in 62. For 31 patients, chronic renal insufficiency (CKD stage 2-5) persisted, including four patients with end-stage kidney disease (CKD stage 5). Seventeen patients suffered recurrence of TMA, and eight patients died.CONCLUSION:
This study clarified differences in the relative proportions of primary diseases between patients from Japan and North America and Europe. The difference may be attributable to the lower estimated incidence of STEC-HUS in Japan.Palavras-chave
