Abstract
The optimal method of assessing protein energy nutritional status in patients receiving home parenteral nutrition (HPN) is unknown. We evaluated protein energy nutritional status in 47 outpatients (23 male; 24 female) on HPN by measuring anthropometry, plasma proteins, and lymphocyte counts and compared these with the results of subjective clinical assessment and bioelectrical impedance measurements. Sixteen of the 47 patients (34%) were underweight (body mass index <5th percentile of the reference) and 21 (45%) were below the 5th percentile of the reference for both triceps skinfold thickness and midarm muscle circumference. Plasma proteins were subnormal in 1-5 patients (2-11%). Lymphocyte counts were subnormal in 19 patients (40%). Clinical assessment classified 23 patients (49%) as well nourished and 24 (51%) as moderately malnourished. Moderately malnourished patients had a significantly lower body mass index than well-nourished patients (P = 0.02). Clinical assessment did not correlate with bioelectrical impedance analysis. Fat-free mass determined by bioelectrical impedance analysis resulted in values up to 9.4 kg lower and 8 kg higher than fat-free mass obtained by anthropometry. Weighing combined with a subjective clinical assessment is sufficient for evaluation of protein calorie nutritional status in patients on HPN.
