Abstract

Background: Tyrosine kinase (TK) inhibitors are increasingly being used to treat a variety of pediatric malignancies. Reports in adult patients describe a range of effects of TK inhibitors on the kidney, including hypertension, proteinuria, acute kidney injury, and thrombotic microangiopathy (TMA); however, there are only a few reports of TK-inhibitor-associated nephrotic syndrome. Methods: We report four pediatric patients with various malignancies (chronic myelogenous leukemia, acute lymphoblastic leukemia, and glioma/renal cell carcinoma) who developed nephrotic syndrome during treatment with TK inhibitors (imatinib, sunitinib, dasatinib, and quizartinib). One of the four patients also had clinical features of TMA. Results: Three of the four patients achieved complete remission of nephrotic syndrome with discontinuation of the TK inhibitor and have had no additional nephrotic syndrome relapses to date. The temporal relationship of nephrotic syndrome onset to TK-inhibitor therapy and resolution of nephrotic syndrome with cessation of therapy strongly imply an association in these patients. Conclusions: TK inhibitors are important therapies in pediatric cancer, and their use is expanding. Nephrotic syndrome with or without features of TMA is a potential complication of these therapies in children.
