The Relationship of Visfatin Levels with Insulin Resistance and Left Ventricular Hypertrophy in Peritoneal Dialysis Patients

Background/objectives: Cardiovascular abnormalities are common in patients with chronic kidney disease. Visfatin influences lipid metabolism, insulin sensitivity, and cardiovascular health. The aim of this study was to explore the relation of serum visfatin to cardiovascular risk factors in nondiabetic peritoneal dialysis (PD) patients. Patients and methods: Eighty-seven nondiabetic patients (mean age 48 ± 15 years, 39 males) under PD were enrolled. Weight, anthropometric measurements, blood pressure, biochemical parameters, and insulin resistance (homeostatic model assessment-insulin resistance-HOMA-IR) were measured. Visfatin was measured and left ventricular mass index (LVMI) was calculated by echocardiography. Results: LVMI was correlated with body mass index (BMI; r = 0.47, p = 0.01), systolic blood pressure (SBP; r = 0.62, p = 0.04), and serum visfatin levels (r = 0.49, p = 0.03). According to HOMA-IR levels patients were grouped as insulin-resistant (IR) (HOMA-IR ≥2.0, n = 35) and noninsulin-resistant (non-IR) (HOMA-IR
