Evaluation of zinc status in subjects with Crohn's disease

Research output: Contribution to journalArticle

Abstract

Zinc status was evaluated in 30 subjects with Crohn's disease. Intestinal resection had previously been performed in 23 of the subjects. The concentrations of zinc were determined in plasma, erythrocytes, percutaneous muscle biopsies, and in urine collected during 24 hours. The results were compared with those in 19 healthy controls. Most of the patients had a normal zinc status. The levels of zinc were, however, reduced (i.e., less than mean −2 SD for controls) in plasma for five, in erythrocytes for two, and in muscle biopsies for six subjects with Crohn's disease. The mean concentrations of zinc in plasma and erythrocytes were reduced (P less than 0.05), whereas the mean content of zinc in muscle biopsies and the mean urinary excretion of zinc were not significantly different, in subjects with Crohn's disease. The various zinc parameters did not correlate to each other. The results indicate that some subjects with Crohn's disease had an intracellular zinc depletion, which, however, was not reflected by a reduction in levels of zinc in plasma.
