    Background: Omentin-1, a novel adipokine identified in visceral adipose tissue, is negatively correlated with different conditions such as diabetes, obesity and inflammation. However, changes in serum Omentin levels associated with the degree of the renal dysfunction and metabolic risk factors in CKD patients has not yet been revealed. In the present study, we aimed to investigate the level of Omentin-1 and related para meters in diabetic and non-diabetic CKD patients. Methods: 64 (30 diabetic, 34 non-diabetic) CKD patients and 27 healthy control subjects enrolled in this cross-sectional study. Anthropometric and laboratory assessment performed and malnutrition and inflammation components evaluated. Serum concentrations of Omentin-1 and insulin were measured by using ELISA. Results: Serum Omentin-1 levels in CKD patients were significantly lower compared to the healthy controls. Further analyze revealed that decreased omentin in CKD patients was due to the reduced omentin levels in the diabetic subgroup. An increase in inflammation and malnutrition components was correlated with a decrease in the serum level of Omentin. Omentin levels were lower in stage 2 and 3 CKD but not stage 4 CKD patients compared to control. Conclusions: The results of the present study suggest that diabetes mellitus and inflammation should be associated with lower omentin levels in CKD population; however, this reduction resolves due to the failure of degradation and excretion of omentin when creatinine clearance falls below 30 ml/min (stage 4 CKD).
