[Content and molecular composition of circulating immune complexes in patients with multiple gastroduodenal ulcers].

In 45 patients with multiple gastroduodenal ulcers the humoral immunity indexes were studied up. Formation of secondary immune deficiency with simultaneous raising of the circulating immune complexes level on account of accumulation in the blood of their most pathogenic middle and small molecular fractions and reduction of large molecular fractions was established in patients with multiple gastroduodenal ulcers.
