NUTRITIONAL PROFILE AND INFLAMMATORY STATUS OF STABLE CHRONIC HEMODIALYSIS PATIENTS AT NEPHROLOGY DEPARTMENT, MILITARY HOSPITAL RAWALPINDI
Abstract
Background: Protein-energy malnutrition (PEM) is common in the haemodialysis population.Identification and management of these patients can result in significant reduction in morbidityand mortality. Aim of the study was to find the prevalence of PEM in otherwise stablehaemodialysis patients at Military Hospital Rawalpindi at a single point in time with the help ofestablished biochemical and physical markers. Material and Methods: Height, dry weight andbody mass index (BMI) were recorded for 64, stable, 14–75 year-old patients who were onhaemodialysis for 3 months. Blood samples were drawn (pre-dialysis) for complete blood count,serum C-reactive protein, serum total protein, serum albumin and serum Creatinine. Ideal bodyweights and BMI were obtained from Pakistan Army Selection and Recruitment standards.Results: Out of 64 patients 43 (67%) were males. Mean age was 44.514.3 yr. Mean haemoglobinwas 8.842 g/dl. Fifty-seven patients (89%) had haemoglobin 11 g/dl. Pearson correlationcoefficient (r) with albumin was significant (p=0.01). The mean serum albumin was 34.24.25 g/l.Serum albumin of less than 40 g/l in 58 patients (90.6%). C-Reactive protein was available for 58(90.6%) of patients. It was positive in 23 (35.9%) and was associated with a lower mean serumalbumin (32.7 g/l vs 35.4 g/l) which was statistically significant (p=0.017). There was nosignificant relationship between the lymphocyte count and albumin levels. However, the Pearsoncorrelation of albumin with the total WBC count gave a p value of 0.05. Mean BMI was 19.82.9kg/m2. Thirty-seven (57.8%) patients had BMI in the normal range (18.5–24.6 kg/m2) and 24(37.5%) were below normal (14.6–18.3 kg/m2). Correlation of albumin with BMI and serumcreatinine was not significant (p= 0.46 and 0.53 respectively). Conclusion: Serum albumin is astrong marker of malnutrition but needs to be associated with other physical and inflammatoryparameters to correctly identify malnourished haemodialysis patients.Key Words: Haemodialysis; nutrition; albumin; C-reactive protein; body mass indexReferences
