Thus, we conducted a 7-year prospective study by first assessing the association among1) the pro-inflammatory cytokines Interleukin-18(IL-18), IL-6, and Interleukin-1ß(IL-1ß) and allcause mortality; 2) these cytokines, age, comorbidities, and malnutrition to find out the mortality predictors for PD patients. Here, IL18 is linked to nutritional deficiency disease.
