Abstract
Amaç: Bu çalışmada akut myeloid lösemi tanılı hastalarda (AML; yeni tanı ve remisyondaki hastalar) oksidatif stres ve DNA hasarı düzeyleri sağlıklı kontrollerle karşılaştırılarak değerlendirilmiştir.
Gereç ve yöntem: Bu çalışmaya üç grup toplam, 96 katılımcı; 32 yeni AML hastası, 32 remisyondaki hasta ve 32 yaş ve cinsiyete uygun sağlıklı birey dahil edildi. Biyokimyasal parametreleri, toplam oksidan durumu (TOS), toplam antioksidan durumu (TAS), oksidatif stres indeksi (OSI) ve DNA hasarını ölçmek için comet testi kullanılarak çeşitli laboratuvar analizleri yapıldı.
Bulgular: TOS seviyelerinin gruplar arasında önemli ölçüde farklılık göstermediğini gösterdik, ancak hem yeni tanı hem de remisyon grupları kontrollerle karşılaştırıldığında daha yüksek OSI seviyeleri sergiledi. TAS seviyeleri remisyon grubunda belirgin şekilde daha düşüktü ve bu da azalmış antioksidan kapasitesini gösteriyordu.
Comet testi, sağlıklı kontrollere kıyasla yeni tanı AML grubunda, ardından remisyon grubunda önemli ölçüde yüksek DNA hasarı gösterdi.
Bu bulgular, AML hastalarında hastalığın patofizyolojisine katkıda bulunabilecek artmış oksidatif stres yükü ve genotoksisiteyi vurgulamaktadır. Dahası, sonuçlar oksidatif stres ve DNA hasarının remisyondaki hastalara kıyasla yeni tanı hastalarda daha belirgin olduğunu göstermektedir.
Sonuç: Çalışmamızda, AML hastalarında özellikle tanı anında gözlenen oksidatif stres ve DNA hasarının hastalığın ilerlemesinde ve tekrarlamasında rol oynayabileceği gösterilmiş olup, AML yönetiminde oksidatif stres belirteçlerinin potansiyel prognostik değere sahip olabileceği düşünülmektedir.

Abstract
Purpose: The present study evaluates the levels of oxidative stress and DNA damage in patients diagnosed with acute myeloid leukemia (AML; newly diagnosed patients and patients in remission) compared to healthy controls.
Materials and methods: A total of 96 participants were enrolled into this study in three groups: 32 newly diagnosed AML patients, 32 patients in remission, and 32 age- and sex-matched healthy individuals. Various laboratory analyses were conducted to measure biochemical parameters, total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and DNA damage using the comet assay.
Results: We showed that while TOS levels did not differ significantly between the groups, both the newly diagnosed and remission groups exhibited higher OSI levels compared to controls. TAS levels were notably lower in the remission group, suggesting decreased antioxidant capacity. The comet assay demonstrated significantly elevated DNA damage in the newly diagnosed AML group, followed by the remission group, relative to healthy controls. These findings highlight an increased oxidative stress burden and genotoxicity in AML patients, which may contribute to disease pathophysiology. Furthermore, the results suggest that the oxidative stress and DNA damage are more pronounced in newly diagnosed patients compared to those in remission.
Conclusion: The study showed that the oxidative stress and DNA damage observed in AML patients, particularly at diagnosis, could play a role in the progression and recurrence of the disease, suggesting potential prognostic value for oxidative stress markers in AML management.
