Assessment of Severity of Malnutrition in Peritoneal Dialysis Patients via Malnutrition: Inflammatory Score

Regarding to the complications of malnutrition in dialysis patients, using an easy and reliable method for evaluating of malnutrition is important in patients with the end‑stage renal disease. Based on the effect of inflammatory factors in malnutrition, A new scale has been designed which is called malnutrition–inflammatory scale (MIS). We designed current study to assess the severity of malnutrition in peritoneal dialysis patients in Isfahan via MIS.

In this cross‑sectional MIS was used for evaluation of malnutrition. MIS includes 10 components: dry weight changes, dietary intake, functional capacity, comorbidity, muscle wasting and loss of subcutaneous fat as well as body mass index (BMI), serum albumin level and total iron binding capacity (TIBC). Each component has four levels of severity from 0 (normal) to 3 (severely abnormal). All analyses were performed using Statistical Package for Social Sciences version 20 (SPSS 20) and P < 0.05 were considered statistically significant.

Results showed no significant difference in MIS between male and female participants. Mean of minimum inhibitory concentration in this study was calculated about 4.1 (MIS <9) which means no or mild malnutrition. Significant correlation between MIS and weight (P < 0.001), BMI (P < 0.001), TIBC (P < 0.001), triglyseride (P = 0.04) and arm circumference (P < 0.001) was seen.

We suggest That MIS is being used as a valuable tool for prevention of fatal outcomes in chronic dialysis patients.
