Secondary thrombotic microangiopathy in two patients with Philadelphia-positive hematological malignancies treated with imatinib mesylate

Abstract: Drug-mediated thrombotic microangiopathy may cause life-threatening medical emergencies. Novel targeted therapies have dramatically changed the prognosis of a number of oncological diseases. Tyrosine kinase inhibitors of the Breakpoint Cluster Region-Abelson (BCR-ABL) oncoprotein are used in patients with chronic myeloid leukemia or Philadelphia chromosome-positive acute lymphoblastic leukemia. Imatinib mesylate, which was the first anti-BCR-ABL tyrosine kinase inhibitor, has demonstrated a high tolerance prof… Show more

“…in the literature, microangiopathic hemolytic anemia (MAHA) secondary to tyrosine kinase inhibitor use is very rare. Three cases have been reported after imatinib use, 13,14 and to our knowledge, only 2 cases of dasatinib-induced MAHA have been reported in the literature. 5,15 We believe that our patient had a side effect of the treatment of the underlying disease, CML (i.e., CML treated with dasatinib leading to TTP, which in turn provoked intracranial hypertension from the underlying anemia and thrombocytopenia).…”

“…Подобный механизм был описан при системных воспалительных заболеваниях [47−50] Лечение ингибиторами сосудисто-эндотелиального фактора роста и тирозинкиназы также ассоциируются с развитием синдромов, подобных аГУС [72−76]. При этом внутриклубочковая ТМА возникала намного чаще при применении ингибиторов сосудисто-эндотелиального фактора роста, чем при применении ингибиторов тирозинкиназы [73,76]. В свою очередь, ингибиторы тирозинкиназы более часто вызывали повреждения подоцитов, как при нефропатии или очаговом гломерулосклерозе [75,76].…”
