OBJECTIVE: In this study, we compared predialysis and dialysis patients with the controls in terms of insulin resistance and evaluated the association with inflammation that is a risk factor for cardiovascular disease.
MATERIALS AND METHODS: A total of 134 non-diabetic patients with controls (n=33), predialysis (n=29) and dialysis patient group (n=72) were included in the study. Fasting blood glucose, insulin, C-peptide, albumin, CRP (C-reactive protein) and homocysteine plasma levels were simultaneously analyzed in all the patients. HOMA-IR index was calculated to show existence of insulin resistance.
RESULTS: Mean insulin and HOMA-IR index values were found to be higher in the predialysis and dialysis patient groups than in the control group (p=0.019, p=0.014; respectively). When three groups were compared in terms of C-peptide levels; these values were found to be statistically significantly higher in the predialysis patients than in controls (p=0.017) and in the dialysis group than in the predialysis patients and controls (p=0.0001, p=0.0001; respectively). CRP and homocysteine levels were found to be statistically higher (p=0.0001, p=0.0001; respectively), while albumin levels were significantly lower (p=0.0001) in the dialysis patient group.
CONCLUSION: In our study, we demonstrated that insulin resistance was higher in patients in the various stages of chronic kidney disease compared to healthy population. We found that insulin resistance, C-peptid and inflammation related cardiovascular risk factors increased.
