Significance of albumin and C-reactive protein variations in 300 end stage renal disease patients in Tehran university of medical sciences hospitals during year 2010

ABSTRACT

Protein-energy malnutrition, wasting and inflammation are frequent complication among patients with end-stage renal disease [ESRD]. Malnutrition is associated with cardiac co-morbidity, inflammation and poor survival in ESRD patients. Serum albumin is a well-known marker of nutrition in ESRD patients. Serum albumin is still the most commonly used nutritional marker in ESRD patients. C-reactive protein [CRP], the major acute phase response [APR] protein is elevated in these patients. High CRP levels are linked to the degree of atherosclerosis in coronary, peripheral, and extracranial brain arteries. The aim of the present study was to investigate nutritional factor [albumin] and CRP levels in ESRD patients. In this cross-sectional study a total of 300 patients who had ESRD and had been on hemodialysis treatment for at least 6 months were selected. The laboratory tests consisted of measurement of CRP and albumin using high sensitive ELISA kits. The study patients included 157 males [52.3%] and 143 females [47.7%] with average age of 41.5 +/- 14.3 years. Mean CRP level was 7.96 mg/ dl [+/- 1.52], mean serum albumin was 4.07 g/dl [+/- 0.19].Of 300 patients, 21 died [7%]. These were patients with serum albumin<4 g/dl and CRP>9.5 mg/dl. This study showed that low albumin and high CRP levels are the main predictors for death. There was a significant difference between CRP and albumin levels in ESRD patients [P<0.0001]. Measuring CRP as a marker of inflammation can be helpful in managing these patients
