| Abstract: | Plasma and skeletal muscle electrolytes were measured in 13 patients with Crohn's disease, and in an age- and sex-matched reference group. Patients with Crohn's disease demonstrated significantly lower muscle potassium content (p less than 0.01) than did controls. Patients with extensive involvement of the bowel tended to have lower muscle potassium content. The patient population did not differ significantly from the controls with regard to skeletal muscle magnesium content but displayed a far wider range of values. Our results indicate that potassium depletion is present in nonresected patients with Crohn's disease. |
