Diabetik retinopatili hastalarda serum vasküler endotelyal büyüme faktörü ve nitrik oksit düzeyleri

Öz:
Amaç: Anjiogenik özellikleri tespit edilmiş olan vasküler endotelyal büyüme faktörü (VEGF) ve nitrik oksit' in (NO) serum düzeyleri ile diabetik retinopati (DRP) evreleri ve tedavi şekilleri arasındaki korelasyonun incelenmesi.Gereç ve Yöntem: Tip 2 diabetes mellitüsü olan 124 hasta ile benzer yaş ve cinsiyet dağılımı gösteren 20 sağlıklı birey çalışmaya alındı. Diabetik hastalar oral antidiabetik ilaç kullanan ve insülin kullananlar olarak ikiye ayrıldı. Her bir grup kendi içinde retinopati evresine göre 1.retinopati yok, 2. zemin DRP, 3. preproliferatif DRP, 4. Proliferatif DRP ve 5. Kontrol şeklinde 4 gruba ayrıldı. Serum açlık VEGF ve NO düzeyleri ölçüldü ve gruplar arasında istatistiksel olarak değerlendirildi. Tüm hastalarda kan basıncı, serum C peptit, albumin, HDL, LDL, Kolesterol, Kreatinin, HbAlc, B12 vitamini, folik asit, fibrinojen, sedimentasyon düzeylerine bakıldı. Bulgular: Gruplar arasında yaş, boy, ağırlık, sistolik ve diastolik kan basıncı, serum C peptit, albumin, HDL, LDL, total kolesterol düzeyleri arasında anlamlı fark izlenmedi. Retinopati grupları arasında serum VEGF ve NO düzeyleri istatistiksel olarak farklı bulunmadı. VEGF, proliferatif DRP grubunda kontrol grubuna kıyasla anlamlı olarak yüksek saptandı (p:0.014). NO ise tüm diabet gruplarında kontrol grubuna kıyasla yüksek saptandı (p:0.034, 0.003, 0.016 ve 0.001). Zemin DRP grubunda NO düzeyi OAD kullananlarda daha yüksek saptanırken (p:0.01), diğer parametreler açısından hiçbir grupta OAD ve insülin kullanan hastalar arasında fark izlenmedi. Sonuç: Serum VEGF ve NO düzeyi proliferatif DRP'li hastalarda yüksek bulunurken bu maddelerin proliferatif retinopati evresine gelmiş hastalarda periferal marker olarak kullanılabileceği ve progresyon veya regresyonun biokimyasal olarak izleminde faydalı olabileceği düşünüldü.

Serum levels of vegf and no in patients with diabetic retinopathy

Öz:
Purpose: To investigate the relationship of serum levels of nitric oxide (NO) and vascular endothelial growth factor (VEGF) with diabetic retinopathy (DRP) grade and treatment modality in patients with diabetes mellitus. Material and Methods: One hundred twenty four patients with type II diabetes mellitus and 20 age and sex matched healthy subjects were enrolled in the study. The diabetic patients were divided into two groups as patients who are receiving oral anti-diabetic (OAD) drugs or patients who are receiving insulin treatment. Both groups were also divided into four subgroups according to stage of retinopathy as following: 1. no retinopathy, 2.background DRP, 3.prepro-liferative DRP, 4. proliferative DRP and 5. control group. In all groups, body mass index was calculated, fasting serum VEGF and NO levels were measured and mean values between groups were statistically evaluated. Blood pressure, serum C peptide, albumin, HDL, LDL, cholesterol, creatinin, HbAlc, vitamin B12, folic acid, fibrinogen and ESR were measured in all patients. Results: There were no statistically significant differences between groups as age, body mass index, systolic and diastolic blood pressure, C peptide, albumin, and HDL, LDL, total cholesterol levels. There was no statistically significant difference in serum VEGF and NO between retinopathy groups. VEGF levels were found to be significantly higher in proliferative DRP group compared to control group (p:0.014). NO levels was found to be higher in all diabetic groups compared to control group (p:0.034, 0.003, 0.016 and 0.001). NO was found to be higher in patients with background DRP in the OAD group compared to insulin group, while there was no difference between two treatment modality in all groups for VEGF levels. Conclusion: Serum levels of VEGF and NO were significantly higher in proliferative retinopathy compared to control group. It was suggested that these parameters can be used as a peripheral marker of proliferative DRP, and may be useful for biochemical follow-up of progression and regression of proliferative process.
