Abstract

OBJECTIVE: Erythropoietin resistance is a serious problem in patients treated with recombinant erythropoietin. Antierythropoietin antibodies are considered to be one of the causes of this resistance. MATERIAL and METHODS: We investigated antierythropoietin antibodies in chronic hemodialysis patients and compared the results with healthy controls by means of establishing an ELISA method. A total of 121 chronic hemodialysis patients receiving recombinant erythropoietin were included in the study. The patients were subdivided according to the type of recombinant erythropoietin (erythropoietin-α or erythropoietin-β) they had been treated with in the last six months. RESULTS: The absorbance values of patients were compared with the absorbance values of the control group by a specific and reproducible method. LOD (limit of detection) and LOQ (limit of quantitation) values were also calculated. The difference in the absorbance values between the therapy and control groups was statistically significant. CONCLUSION: Both erythropoietin-α and erythropoietin-β induce production of antibodies against erythropoietin. Anti rh-EPO antibodies may play a role in EPO resistance.

Özet

AMAÇ: Eritropoietin direnci rekombinant eritropoietin ile tedavi edilen hastalarda ciddi bir sorundur. Antieritropoietin antikorlar, bu direncin nedenlerinden biri olarak kabul edilir. GEREÇ ve YÖNTEMLER: Kronik hemodiyaliz hastalarında ELISA yöntemi oluşturmak suretiyle antieritropoietin antikorları araştırıldı ve sonuçları sağlıklı kontrollerle karşılaştırıldı. Rekombinant eritropoetin alan 121 kronik hemodiyaliz hasta çalışmaya alındı. Hastalar bu son altı ay içinde tedavi edilmiş rekombinant eritropoietinin (eritropoietin - α ya da eritropoietin - β ) tipine göre ayrıldı . BULGULAR: Hastaların absorbans değerleri spesifik ve çoğaltılabilir bir yöntem ile kontrol grubunun absorbans değerleri ile karşılaştırıldı. LOD (saptanma limiti) ve LOQ (niceliklendirme sınır) değerleri de hesaplandı. Tedavi ve kontrol grubu arasında absorbans değerleri farkı istatistiksel olarak anlamlı idi. SONUÇ: Hem eritropoietin-α hem de eritropoietin-β eritropoietine karşı antikorların üretimini başlatabilir. Anti rh-EPO antikorları EPO direninde rol oynayabilir.
