Objectives: Neutrophil/lymphocyte ration (NLR) and platelet/lymphocyte ratio (PLR) levels can be used as systemic infallamotory parameters. Asymmetric dimethyl arginine (ADMA) inhibits endothelial nitric oxide synthase. Phase Angle (PhA) is a potential paremeter to screen for inflammatory abnormalities. In present study we aimed to determine the relations between NLR, PLR, ADMA, and PhA in terms of early markers for nutritonal status in addition to their well-known role in inflammation. Methods: A total of 89 patients undergoing maintenance hemodialysis 3 days a week at least 6 months were enrolled. To assess nutritional status, we performed the dietary questionnaire and mini nutritional assessment score (MNAS). ADMA was measured by ELISA. NLR and PLR are calculated from monthly complete blood count tests. Patients were divided into 2 groups accordng to NLR levels as group 1 (NLR≥4.6; n=48) ve and group 2 (NLR<4.6, n=41). Results: The mean ADMA level was 0.03±0.01 µmol/L, the mean PhA was 7.2±1.1º. In subgroup analysis, MNAS, albumin levels and phase angle of patients in group 1 were lower and CRP, PLR, ADMA levels were higher when compared to group 2. In correlation analysis, NLO was positively correlated with PLR, CRP and ADMA however negatively correlated with albumin and PhA levels. In regression analysis, NLR, PLR and ADMA were detected as independent predictors of MNAS. Conclusion: In conclusion our study suggests that NLR, PLR and ADMA are independent predictors for nutritional status and inflammation in patients ongoing hemodialysis.
