Abstract

Paroxysmal nocturnal hemoglobinuria (PNH) is characterized by the triad of intravascular hemolysis, venous thrombosis, and cytopenia. Treatment of PNH is generally supportive. Bone marrow transplan- tation is the only curative therapy for PNH, but is associated with significant morbidity and mortality. Herein, we present a patient with PNH that received eculizumab, a humanized monoclonal antibody that blocks activation of the terminal complement at C5, before and immediately following allogeneic peripheral stem cell transplantation. Prior to hematopoietic stem cell transplantation eculizumab treatment markedly reduced hemolysis and transfusion requirement; however, 1 d post transplantation a hemolytic episode occured, which was successfully stopped with eculizumab re-treatment. Afterwards the patient did not require additional transfusions. The results of this study indicate that early admin- istration of eculizumab may be a safe and effective therapy for hemolytic episodes associated with allogeneic peripheral stem cell transplantation in patients with PNH.

Özet

Paroksismal noktürnal hemoglobinüri (PNH) intravasküler hemoliz, venöz trombozlar ve sitopenilerden oluşan bir triadla kendini gösterir. Hastalığın tedavisi genellikle destekleyici türdedir. Kök hücre nakli tek şifa sağlayıcı tedavi yolu olmakla birlikte, anlamlı oranda morbidite ve mortaliteyle birliktedir. Burada ekulizumab (C5 düzeyinde terminal kompleman aktivitesini inhibe eden monoklonal insan kaynaklı antikor) tedavisinin işlem öncesi ve hemen sonrasında kullanıldığı bir allojeneik çevresel kök hücre transplantasyonu olgusunu sunmak istedik. Ekulizumab, allojeneik nakil öncesinde kullanıldığında hastanın hemoliz ataklarında ve transfüzyon ihtiyacında belirgin bir azalma gözlendi. Bununla birlikte, naklin ilk gününde meydana gelen hemolitik atak nedeniyle ekulizumab uygulaması tekrarlandı. Hemolitik atak başarıyla tedavi edilirken, sonrasında hastanın transfüzyon ihtiyacı olmadı. Bu olgu sunumu bize, PNH'lı ve allojeneik periferik kök hücre nakli uygulaması yapılan hastalarda meydana gelebilecek hemolitik atakların tedavisinde ekulizumabın güvenli ve etkili bir şekilde uygulanabileceğini düşündürmektedir.
