Purpose Chronic kidney disease has profound effects on the health-related quality of life (HRQoL) of patients, with serious physiological, psychological and socio-economic implications. The co-occurrence of protein-energy wasting and inflammation in endstage renal disease patients is associated with worse HRQoL and increased mortality. We designed this study to examine the relationship between nutritional and inflammatory status and HRQoL in kidney transplant recipients. Methods: Data from 100 randomly selected kidney transplant patients were analyzed in a cross-sectional survey. Socio-demographic parameters, laboratory results, transplantation-related data, comorbidities, medication and malnutrition-inflammation score (MIS) (Kalantar Score) were tabulated at baseline. Patients completed the Kidney Disease Quality of Life- SF (KDQoL-SF™) self-administered questionnaire. Results: Mean age was 51 ± 13 years, median (interquartile range, IQR) time since transplantation 66 (83) months, 57% were men, and 19% had diabetes. The median (IQR)MIS was 3 (3). TheMIS significantly and negatively correlated with almost all HRQoL domains analyzed, and this association remained significant in multivariate linear regression analysis for log-transformed scores on energy/fatigue (β = -0.059 P<0.001), bodily pain (β = -0.056 P = 0.004), physical functioning (β = -0.029, P = 0.022) and symptoms/problems (β = -0.023P = 0.005) domains after statistical correction for age, gender, eGFR, dialysis vintage, Charlson Comorbidity Index and occupational status. Additionally, cubic spline analyses revealed linearly increasing, "dose-response" relationship between almost all domains of KDQoL-SFTM and the MIS. Conclusions Malnutrition-inflammation score is independently associated with different dimensions of HRQoL in kidney transplant recipients.
