In this study, subjects with intradialytic hypertension were older and had significantly lower hemoglobin, lower nPCR as a marker of protein intake and malnutrition, and lower i-PTH, although they had higher hsCRP resulting in the cooccurrence of malnutrition, inflammation, and atherosclerosis (MIA syndrome), in comparison to the patients without intradialytic hypertension. This evidence concerns the gene PTH and nutritional deficiency disease.
