The aim of this study was to determine if a defect in ventilatory function is present in patients with chronic peptic ulcer and if so, is it present in both gastric and duodenal ulcer and is it related to smoking. Fifty-six patients with peptic ulceration (27 gastric ulcer, 29 duodenal ulcer), together with 56 healthy controls matched for age, sex, and smoking status, were studied. Ventilatory function was measured and the ABH blood group antigen secretor status was determined. Vital capacity and forced expiratory volume in 1 s were significantly reduced in both smokers and nonsmokers with gastric ulcer when compared with controls; total lung capacity was lower than controls only in smokers with gastric ulcer. In duodenal ulcer patients, a trend similar to that observed in gastric ulcer patients was present. It is concluded that a defect in ventilatory function is present in patients with chronic gastric ulcer; a lesser defect is present in patients with duodenal ulcer.

A study of the IgA levels in 43 duodenal ulcer (DU) patients and 8 gastric ulcer (GU) patients and their comparison with healthy controls reveals significantly elevated levels of IgA in DU and somewhat lower levels in GU. The levels were also associated with the genotypes of the patients for genetic markers such as ABO blood group, ABH sectetor status, haptoglobin, and alkaline phosphatase enzyme. Nutritional factors, such as vegetarianism, chili consumption, and habits such as smoking and alcoholism also showed variation in the IgA levels. These results indicate the response and role of IgA in the immunological mechanisms involving mucosal protection and autoimmunity in ulceration processes in the stomach.

The ABO blood group and ABH secretor status have been determined for 368 patients with a duodenal ulcer, 202 patients with a gastric ulcer, 83 patients with a stomal ulcer, 105 patients with gastric cancer, 102 patients with diabetes mellitus, and a control group of 610 subjects consisting of healthy persons and of patients with other conditions attending the same hospital. The results have been analysed in conjunction with those reported in two other large series. For duodenal ulcer the results show that the relative incidence among non-secretors compared with secretors is 1.80 to 1, with 95% confidence limits of 1.55 to 1 and 2.03 to 1. For gastric ulcer the relative incidence is 1.42 to 1, with 95% confidence limits of 1.16 to 1 and 1.74 to 1. Comparison of the results for the two types of peptic ulcer shows that they are significantly different from one another. For both types of ulcer, the estimated risk among non-secretors was similar for blood group O and for the other blood groups and the results suggest that the specific risks associated with blood group O and with non-secretion multiply one another. It is concluded that the mechanisms by which blood group O and non-secretion affect the risk of developing a gastric or duodenal ulcer are related to one another; but that they do not depend on the presence of the blood group substances in the secretions. The proportion of non-secretors among patients with a stomal ulcer (49%) was higher than among patients with a duodenal ulcer (37%) and the order of the relationship between non-secretion and the three types of peptic ulcer (stomal, duodenal, and gastric) was the same as that for blood group O. Other data suggest that there may be a slight increase in the risk of gastric cancer among non-secretors, but that the occurrence of diabetes mellitus is independent of ABH secretion.
