[Use of organic forms of selenium in nutrition of patients with gastrointestinal diseases].

Selenium level was determined in sera of 27 patients including 15 patients with chronic gastrointestinal diseases and 12 patients with intestinal malabsorption after some kinds of stomach or small intestine resection. Deficiency of this trace element was found in 5 patients and suboptimal concentration in 4 patients in the first group and in 3 and 5 patients of second group respectively. Supplementation of patients with 45 mg of selenium organic form based on autolysis extract of selenious baker's yeast resulted in increase of selenium level in 23 (85%) patients including all of them with selenium deficiency or suboptimal level. It was concluded about high bioavailability of selenium in supplement studied. Perturbed intestinal absorption after surgical resection of stomach or small intestine may be considered as an indication for prophylactic taking of organic selenium form preparation.
