Abstract

Aim: To evaluate new biomarkers such as YKL-40, preptin, and nitric oxide (NO) in patients with diabetes and to assess its relation to cardiorenal injury.

Patients and methods: The study included 62 patients with type 1 diabetes and 30 healthy volunteers. Blood sample was taken for assessment of glycosylated hemoglobin, lipid profile, YKL-40, preptin, and NO. Also, urine sample was taken for analysis of albumin/creatinine ratio. Echocardiography was also done.

Results: NO was lower, whereas YKL-40, preptin, and albumin/creatinine ratio were significantly higher in patients with diabetes. NO had a significant negative correlation with LVEDD, LVESD, PWT, LV mass, YKL-40, preptin, and albumin/creatinine ratio. YKL-40 had a significant positive correlation with waist/height ratio, preptin and negative correlation with E/A ratio. Stepwise multiple regression revealed that E/A ratio is the only parameter related to YKL-40. On the contrary, NO and systolic blood pressure are related to preptin.

Conclusion: A significant reduction of NO and elevation of YKL-40 and preptin was found in patients with diabetes. A decrease in NO is associated with diastolic dysfunction, LV hypertrophy, and renal impairment, whereas YKL-40 is associated with diastolic dysfunction. An increase in preptin level was associated with hypertension.
