The pathogenic process of inflammation is typically complicated and multifactorial, involving both dialysis-related and dialysis-unrelated factors, which may lead to malnutrition, an adverse cardiovascular prognosis, and mortality in patients undergoing PD [20]. Certain inflammatory markers, such as C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to-lymphocyte ratio (MLR), which represent the systemic inflammatory response, are independent predictors of mortality in patients with PD [5, 18, 21]. This evidence concerns the gene CRP and nutritional deficiency disease.
