title: Malnutrition inflammation complex syndrome in maintenance haemodialysis patients.
abstract: Malnutrition inflammation complex syndrome (MICS) occurs in maintenance haemodialysis (MHD) patients and is a strong predictor of morbidity and mortality in these patients. The aim of our study was to evaluate the influence of inflammation on the biochemical and anthropometrical parameters of the nutritional status in MHD patients. Our study was made on 154 patients (93 men and 61 women, mean age=54.7 yrs. and mean time on dialysis 84 months) over a period of 6 months. The indicator of inflammation, C-reactive protein (CRP), was measured monthly at the central laboratory by nephelometry. The assessment tools used to evaluate the influence of inflammation on the nutritional status in MHD patients were: serum albumin and cholesterol level, midarm circumference (MAC), midarm muscle circumference (MAMC), triceps skin fold thickness (TSF) and body mass index (BMI). Student's t-test was used for group mean comparison between men and women. Person's correlation r was used to determine the significance and the strength of associations. The CRP level was significantly greater in men than in women (12.9 vs. 7.97, p < 0.04). The CRP level showed a strong correlation only with the serum concentration of cholesterol (r=0.49, p < 0.000), and did not correlate with the serum albumin of the MHD patients. There was no correlation between the CRP level and the anthropometrical parameters of the MHD patients in our study. Two separate processes, inflammation and reduced protein intake, each separately contributed to causing a decrease in serum albumin concentration and anthropometrical measurements. The levels of acute phase proteins vary widely as opposed to the serum albumin level; for that reason, changes in the albumin catabolic rate or synthesis require a considerable time to become visible. The average value of the protein catabolic rate of the patients in our study was 1.01 g/kg/d, a value that showed adequate protein intake. These findings would suggest that clinical attention to the maintenance of adequate nutrition could blunt the effects of inflammation on both somatic and visceral protein stores.
