Abstract

Purpose: To investigate the role of serum iron metabolism parameters in age-related macular degeneration (ARMD). Materials and Method: Twenty-four patients with dry ARMD (Group 1), 20 patients with wet ARMD (Group 2) and 25 healthy controls (Group 3) who were followed up at ophthalmology department of Ataturk Training and Research Hospital between November 2014 and April 2015 were included in this study. Diagnosis of ARMD was made by optical coherence tomography and fl uorescein angiography. Serum iron, ferritin, transferrin, total iron binding capacity (TIBC) and hemoglobin level were measured in all patients.Results: There was no statistically signifi cant difference between groups in terms of sex and age (p=0.06, p=0.45; respectively). The mean serum iron levels were similar in Group 1 (66.4 ± 17.9 ?g/dL) and Group 2 ((80.7 ± 35.8 ?g/dL) (p=0.59) and the higher levels in these groups were statistically signifi cant when compared to Group 3 ((58.2 ± 22.5 ?g/dL) (p=0.01, p=0.02; respectively). The mean serum ferritin levels were higher in Group 2 (104.2 ± 79.2 ng/mL) than Group 1 (74.9 ± 54.2 ng/mL) and Group 3 (55.8 ± 39.8 ng/mL) (p=0.03, p=0.01; respectively). The mean serum ferritin levels were higher in Group 1 when compared to Group 3 (p=0.04). The mean TIBC, serum transferrin and hemoglobin levels were similar among three groups (p=0.68, p=0.29, p=0.09; respectively).Conclusions: The higher level of serum iron and ferritin levels in ARMD may be related to iron accumulation in retinal tissues due to breakdown of blood-retinal barrier. Further studies are needed to understand the exact role of iron as a source of oxidative stress in ARMD.

Özet

Amaç: Yaşa bağlı maküla dejenerasyonunda (YBMD), serumda demir metabolizması parametrelerinin rolünü araştırmak.Gereç ve Yöntemler: Kasım 2014 - Nisan 2015 tarihleri arasında Ankara Atatürk Eğitim ve Araştırma Hastanesi Göz Kliniği'ne başvuran 24 kuru tip YBMD hastası Grup 1; 20 yaş tip YBMD hastası Grup 2'yi oluştururken; 25 sağlıklı birey kontrol grubunu (Grup 3) oluşturdu. YBMD tanısı, optik koherens tomografi ve bazı olgularda fl urosein anjiografi ile konuldu. Tüm hastaların serum demir, ferritin, transferrin, total demir bağlama kapasiteleri (TDBK) ve hemoglobin düzeyleri ölçüldü.Bulgular: Gruplar arasında cinsiyet ve yaş arasında istatistiksel olarak anlamlı fark saptanmadı (p = 0.06, p = 0.45 sırasıyla). Ortalama serum demir düzeyleri, Grup 1 (66.4 ± 17.9 ?g/dL) ve Grup 2 (80.7 ± 35.8 ?g/dL) arasında benzer (p = 0.59) iken; her iki gruptaki düzeyler Grup 3'e (58.2 ± 22.5 ?g/dL) göre istatistiksel olarak anlamlı olarak daha yüksek tespit edildi (p = 0.01, p = 0.02; sırasıyla). Grup 2'deki ortalama serum ferritin (104.2 ± 79.2 ng/mL) değerlerinin Grup 1 (74.9 ± 54.2 ng/mL) ve Grup 3'ten (55.8 ± 39.8 ng/mL) yüksek olduğu izlendi (p = 0.03, p = 0.01; sırasıyla). Grup 1'deki ortalama serum ferririn düzeyleri de Grup 3'ten daha yüksek tespit edildi (p = 0.04). Her üç grupta, ortalama TDBK, ortalama serum transferrin düzeyleri, ortalama hemoglobin düzeyleri arasındaki fark istatistiksel olarak anlamlı değildi (p = 0.68, p = 0.29, p = 0.09; sırasıyla).Sonuç: YBMD'li hastalarda saptanan yüksek serum demir ve ferritin seviyeleri YBMD'de görülen kan retina bariyerinin hasarlanmasına bağlı olarak, retinal dokularda demir birikimine sebep olabilir. Oksidatif stres kaynağı olan demirin YBMD patogenezindeki tam rolünü anlamak için daha ileri çalışmalara ihtiyaç vardır.
