Relationship between geriatric nutritional risk index and subpopulation lymphocyte counts in patients undergoing hemodialysis and peritoneal dialysis

We investigated the relationship between geriatric nutritional risk index (GNRI) and subpopulation lymphocyte counts (SLCs) in hemodialysis (HD) and peritoneal dialysis (PD) patients and evaluated whether they can be helpful in the diagnosis of malnutrition in these patients. We examined the GNRI and SLCs of 50 HD patients (mean: 55.8 ± 12.7 years; 28 men and 22 women) and 16 Continuous Ambulatory Peritoneal Dialysis (CAPD) patients (mean: 49.8 ± 14.5 years; 10 men and six women). The GNRI is calculated based on the serum albumin level, dry weight, and ideal body weight and uses the following equation: GNRI = [14.89 × albumin (g/dL)] + [41.7 × (weight/ideal body weight)]. SLCs were evaluated using flow cytometry. T-tests and χ
