Abstract

Introduction: Rheumatoid arthritis (RA) is a chronic and inflammatory disease. Anemia is common in RA. The aim of this study was to investigate the relationship between erythropoietin (Epo) and tumor necrosis factor-alpha (TNFα) in patients with RA. Material and Method: In this study, 32 anemic and 31 non-anemic of total 63 RA patients and 20 healthy controls were compared. Patients with RA were classified as anemic and non-anemic according to the hemoglobin values, with a limit of 12 g/dl in women and 13 g/dl in men. Anemic patients were classified as iron deficiency (n = 15) and chronic disease anemia (n = 17) according to ferritin and iron levels. Serum TNFα, Epo, CRP, RF, ferritin, iron, iron binding capacity, hemoglobin, hematocrit and sedimentation levels were determined. Results: As a result of this study, Epo and TNFα levels of all RA patients were higher than the control group (p <0.003, p <0.008). There was also a positive correlation between TNFα and Epo levels (r = 0.556, p <0.0001). CRP and RF levels were also positively correlated with TNFα and Epo levels. Conclusion: The anemia observed in RA was accompanied by an increase in serum levels of TNFα and Epo, in addition to inhibiting erythropoiesis, the positive correlation of TNFα with CRP and RF suggested that TNFα may have a central role in the pathogenesis of RA.

Özet

Giriş: Romatoid artrit (RA) kronik ve inflamatuvar bir hastalıktır. Anemi, RA’de sık olarak gözlenmektedir. Bu çalışmada RA hastalarındaki anemide eritropoietin (Epo) ve tümör nekroz faktörü-alfa (TNFα) ilişkisi incelendi. Gereç ve Yöntem: Çalışmada 32 anemik, 31 anemik olmayan 63 RA’li hasta ile 20 sağlıklı kişiden oluşan kontrol grubu karşılaştırıldı. RA’li hastalar hemoglobin değerleri kadınlarda 12 g/dl, erkeklerde ise 13 g/dl sınır alınarak anemik ve anemik olmayanlar, anemik hastalar ise ferritin ve demir düzeyleri göz önüne alınarak demir eksikliği (n=15) ve kronik hastalık anemisi olanlar (n=17) şeklinde sınıflandırıldı. Serum TNFα, Epo, CRP, RF, ferritin, demir, demir bağlama kapasitesi, hemoglobin, hematokrit ve sedimentasyon düzeyleri belirlendi. Bulgular: Bu çalışmanın sonucunda tüm RA’ li hastaların Epo ve TNFα düzeyleri kontrol grubuna göre yüksek bulundu (p<0.003, p<0.008). Aynı zamanda TNFα ve Epo düzeyleri arasında pozitif korelasyon olduğu tespit edildi (r=0.556, p<0.0001). CRP ve RF düzeyleri de TNFα ve Epo düzeyleri ile pozitif korelasyon gösteriyordu. Sonuç: RA’de görülen aneminin serum Epo ve TNFα düzeylerinin artışı ile birlikte seyrettiği, TNFα’nın CRP ve RF ile pozitif korelasyonunun eritropoezi inhibe edici etkisinin yanında RA patogenezinde de santral rolü olabileceğini desteklemiştir.
