초록	Background: No standard method for assessing the nutritional status in dialysis patients. In the present study, we undertook an evaluation to determine whether estimation of Onodera’s Prognostic Nutritional Index (OPNI) and lymphocyte subset counts can be helpful in diagnosis of malnutrition in hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Methods: We examined the OPNI and lymphocyte subset counts of 50 HD patients (55.8±12.7 years; 28 men and 22 women) and 16 CAPD patients (49.8±14.5 years; 10 men and 6 women). The OPNI is calculated based on the serum albumin level and total lymphocyte count and uses the following equation: OPNI=10×serum albumin (g/dL)+ 0.005×total lymphocyte count (/mL). Logistic regression analysis was performed for predicting malnutrition in dialysis patients. Results: The average OPNI value was 47.0±4.6 in HD patients and 39.5±4.3 in CAPD patients. Lymphocyte subset counts were not different between HD patients and CAPD patients. Lymphocyte subset counts were lower in patients with higher OPNI (OPNI ≥45). According to logistic regression for predicting malnutrition according to GNRI, age, CAPD and CD 19 count predicted malnutrition in hemodialysis and peritoneal dialysis patients Conclusions: These results suggest that OPNI and lymphocyte subset counts (especially CD 19 count) may be a significant nutritional marker in HD and CAPD patients.
