Abstract

BACKGROUND/AIM:

As chronic inflammation underlies both atherosclerosis and malnutrition, a possible link between these factors has been suggested in hemodialysis (HD) patients. We designed this study to compare nutritional indices and inflammatory parameters of HD patients with demonstrated atherosclerosis (group I) and HD patients without (group II).

METHODS:

We included 59 and 57 patients in groups I and II, respectively. The patient groups were matched for the risk factors for atherosclerosis such as age, gender, smoking habits, hypertension, and HD duration. The nutritional status of the patients was evaluated according to laboratory parameters, normalized protein catabolic rate, anthropometric measurements, and subjective global assessment.

RESULTS:

Laboratory parameters (albumin, prealbumin, total cholesterol, phosphorus, creatinine), normalized protein catabolic rate, and triceps skinfold thickness revealed a significant decline in the nutritional status of the patients with atherosclerosis. We found that the patients with atherosclerosis had significantly higher C-reactive protein, ferritin, and fibrinogen levels when we compared the patient groups for acute-phase reactants. When we assessed malnutrition as being in category B/C (B = mild to moderately malnourished, C = severely malnourished) according to subjective global assessment and inflammation on the basis of a C-reactive protein level > or =10 mg/l, among patients with atherosclerosis, there was a significantly higher proportion of them having malnutrition and inflammation. Additionally, the proportion of patients without any evidence of malnutrition and inflammation was significantly lower in group I than in group II.

CONCLUSION:

Our study gives evidence for the possible triad of malnutrition, inflammation, and atherosclerosis in HD patients.
