Abstract

The impacts of serum iron parameters and/or radiological evidence of systemic iron overload on the prognosis of hematopoietic stem cell transplantation (HSCT) in acute leukemia are controversial. Unfortunately, some of the studies evaluating iron overload in transplant setting did not precisely show the patients with iron overload, mainly due to ignoring consideration of transferrin saturation along with hyperferritinemia for elimination of non-iron overload etiologies of hyperferritinemia. The aim of this study is to assess the effect of iron overload on transplantation related complications and prognosis in acute leukemia. Patients who undergone allogeneic HSCT for acute leukemia in Hacettepe University Medical School Department of Hematology were screened retrospectively in order to find cases with serum iron tests within 9 months before transplant. The endpoints investigated were overall and disease-free survivals, acute and chronic graft-versus-host disease and veno-oclussive disease (VOD). There were 84 patients suitable for inclusion. When various ferritin plus transferrin saturation (TS) cut-off values were investigated for a possible relationship with major transplant-related complications/results only ferritin> 2000 plus TS> 45% was found to have an association with VOD at borderline significance (p= 0.067). In conclusion, we observed a non-significant borderline relationship between iron overload and post-transplant VOD. We did not confirm other post-transplant complications reported in the literature. It must be noticed that although many studies intended to investigate the relationship between iron status and transplant outcomes, only a few of them have really looked for the effect of iron overload.

Özet

Serum demir parametrelerinin ve/veya radyolojik olarak saptanan sistemik demir yüklenmesinin, kök hücre nakli (KHN) yapılmış akut lösemi hastalarının prognozuna olan etkisi tartışmalıdır. Ne yazık ki, demir yüklenmesinin transplantasyona olan etkisini araştıran bazı çalışmalarda demir yüklenmesi olan hastalar doğru bir şekilde saptanamamıştır. Bunun nedeni hiperferritineminin demir yüklenmesi dışındaki sebeplerinin göz ardı edilmesidir. Bu çalışmanın amacı, demir yüklenmesinin akut lösemi hastalarının prognozuna ve transplantasyon ile ilişkili komplikasyonlarına olan etkisinin araştırılmasıdır. Transplantasyon öncesi dokuzuncu aya kadar olan serum demir testleri olan hastaları bulmak amacıyla, Hacettepe Üniversitesi Tıp Fakültesi Hematoloji Departmanı'nda allojenik KHN yapılan hastalar retrospektif olarak taranmıştır. Çalışma sonlanım noktaları, genel ve hastalıksız sağkalım süreleri, akut ve kronik graft versus host hastalığı ve venookluziv hastalıktır (VOH). Çalışmaya alınma kriterlerine uyan 84 hasta mevcuttu. Transplant ilişkili komplikasyonlar ile demir yüklenmesi arasında bir ilişki bulabilmek amacı ile transferrin satürasyonu (TS) ve ferritinin değişik eşik değerleri araştırıldı. Sadece ferritin> 2000+TS> %45 olan hasta grubu ile VOH gelişimi arasında sınırda anlamlılık saptandı (p= 0.067). Sonuç olarak, biz bu çalışmada demir yüklenmesi ve transplantasyon sonrası VOH arasında anlamlı olmayan sınırda bir ilişki saptadık. Literatürde saptanan diğer transplantasyon sonrası komplikasyonlar bizim çalışmamızda saptanmadı. Vurgulamak gerekir ki, birçok çalışma demir yüklenmesi ile transplantasyon sonuçları arasındaki ilişkiyi araştırmayı amaçlasa da ancak birkaç tanesinde demir yüklenmesinin etkisi doğru bir şekilde araştırılabilmiştir.
