An increase in the interest in the cellular immunity in patients with peptic and duodenal ulcers dates back to the detection of histamine H2 receptors on T-cells. In vitro effect of theophylline on T-cells in patients with peptic and duodenal ulcers was investigated. The experiment included 107 patients: 60 with peptic and duodenal ulcers and 47 controls. The experiment was carried out with theophylline test enabling to divide the whole population of T-cells forming active and "late" rosettes (ARCF and TRCF, respectively) into three subpopulations: theophylline-resistant, theophylline-sensitive, and theophylline-dependent T-cells. Increased number of theophylline-dependent T-cells and significantly reduced baseline value of rosette-forming T-cells (p greater than .02) were found in patients with duodenal ulcer. Theophylline-dependent lymphocyte number was the highest in TREC rosette fraction in patients with duodenal ulcer. Statistically significant (p greater than .01; p greater than .05) and independent of patients' age tendency to an increase in the number of theophylline-sensitive T-cells in TRFC rosettes was seen in both peptic and duodenal ulcers. Theophylline-resistant lymphocytes ratio to theophylline-sensitive ones in TRFC rosettes was also significantly lower in patients with peptic ulcer. No correlation between these results and patients age was found in both the control group and patients with the ulcerative disease. An increase in theophylline-dependent T-cells in patients with duodenal ulcer suggests an increase in the number of immature forms of T-cells and indicate an important role of T-cells maturation disorders in the pathogenesis of duodenal ulcer.
