Abstract

Purpose: To investigate the relationship of serum leptin levels with stages of diabetic retinopathy and treatment modality. Materials and Methods: Eighty six patients with type II Diabetes Mellitus and 22 age and sex matched healthy subjects were enrolled in the study. The diabetic patients were divided into four groups according to stage of retinopathy. All groups were also divided into two subgroups as patients taking oral antidiabetic drugs (OAD) or patients who taking insulin treatment. In all groups, body mass index was calculated, fasting serum leptin levels were measured and mean values between groups were statistically evaluated. Results: There were no statistically significant differences between groups with respect to age, body mass index, systolic and diastolic blood pressure, serum HbA1C, and total cholesterol levels. Proliferative diabetic retinopathy (PDR) group had significantly higher leptin levels among the retinopathy groups (background diabetic retinopathy, p: 0.018; preproliferative diabetic retinopathy, p: 0.033). The mean serum leptin level was 19.6±11.3 ng/ml in the control group and 42.5±22.7 ng/ml in the PDR group. The difference in leptin levels between two groups was statistically significant (0.006). When comparing the subgroups, OAD subgroup had significantly higher leptin levels compared to insulin subgroup in the PDR group (p:0.037). Although leptin levels were lower in the insulin subgroups compared to OAD subgroups in other retinopathy groups, differences were not statistically significant. Conclusion: While serum leptin levels were significantly higher in patient with PDR, its levels in patients with non-proliferative retinopathy or without retinopathy did not show significant difference when comparede with the control group. It seems that the serum leptin levels are lower in patients taking insulin treatment.

Özet

Amaç: Serum leptin düzeyi ile diabetik retinopati evreleri ve tedavi şekli arasındaki ilişkinin incelenmesi. Gereç ve Yöntem: Tip 2 diabetes mellitusu olan 86 hasta ile benzer yaş ve cinsiyet dağılımı gösteren 22 sağlıklı birey çalışmaya alındı. Diabetik hastalar retinopati evresine göre 4 gruba ayrıldı. Her bir grup kendi içinde oral antidiabetik (OAD) ilaç kullanan ve insülin kullananlar olarak ikiye ayrıldı. Tüm bireylerde vücut kitle indeksi hesaplandı. Serum açlık leptin düzeyleri ölçüldü ve gruplar arasında istatistiksel olarak değerlendirildi. Bulgular: Gruplar arasında yaş, vücut kitle indeksi, sistolik ve diastolik kan basıncı, serum HbA1C, total kolesterol düzeyleri arasında anlamlı fark izlenmedi. Retinopati grupları arasında leptin düzeyleri proliferatif diabetik retinopati (PDR) grubunda istatistiksel olarak yüksek bulundu (zemin diabetik retinopati, p:0.018; preproliferatif diabetik retinopati, p:0.033). Kontrol grubunda serum leptin düzeyi 19.6±11.3 ng/ml, PDR grubunda 42.5±22.7 ng/ml olarak saptandı. İki grup arasındaki leptin düzeyi istatistiksel olarak anlamlı derecede farklı bulundu (p:0.006). Retinopati grupları tedavi şekline göre kıyaslandığında sadece PDR grubunda OAD alt grubu insülin alt grubuna göre daha yüksek leptin düzeyine sahipti (p:0.037). Diğer gruplarda insülin alt gruplarında leptin düzeyleri daha düşük iken farklar istatistiksel olarak anlamlı değildi. Sonuç: Serum leptin düzeyi PDR’li hastalarda yüksek bulunurken retinopatisi olmayan veya non-proliferatif diabetik retinopatili hastalardaki düzeyi kontrol grubuna göre anlamlı farklılık göstermedi. İnsülin tedavisi alanlarda serum leptin düzeyinin daha düşük olduğu gözükmektedir.
