Assessment of nutritional status and biomarkers among chronic haemodialysis patients
MetadataShow full item record
Although biomarkers have significance on the nutritional status, there is little information about its relationship among patients on maintenance haemodialysis (MHD). The study was done to determine the significance of the relationship between nutritional status and biochemical markers among chronic haemodialysis patients. The study was done at Kenyatta National Hospital (KNH), Nairobi-a teaching and a referral hospital. This was a cross-sectional, prospective study among chronic haemodialysis patients. Fifty patients on chronic maintenance haemodialysis for 3 months and more were included in the study which was carried out May 2012. All eligible study subjects gave informed consent. Biochemical tests of albumin, electrolytes: sodium and potassium and urea were done and anthropometric measurements taken. The reagents for all biochemical analysis were provided by JAS INC., Court Miami Lakes Florida. The relationship between nutritional status and dietary intake, anthropometric status primary diagnosis, co-morbid, socio-demographic factors and dialysis related factors were determined. Fifty subjects were recruited in the study. The consent for the study was sought at Kenyatta National Hospital/University of Nairobi Ethics and Research Committee (KNH/UON ERC). Electrolytes mainly potassium were elevated. Sodium and albumin was low. There were significant correlations between albumin and hospital attendance, albumin and nutritional counseling and BMI with anthropometric parameters. The electrolyte levels of sodium and potassium are useful nutritional biomarkers for HD patients coupled with regular nutritional advice. Anthropometric parameters and BMI can be used for nutritional status assessment.
