Controlled trial of azathioprine in Crohn's disease.

The effect of azathioprine in patients with active Crohn's disease has been evaluated in a double-blind cross-over trial. Fifteen patients were treated with both azathioprine and placebo: only two improved while on azathioprine, six got worse, and in seven there was no change. The drug seemed to be the cause of deterioration in two of the patients. Although the drug may be of some value in a few patients, it should be used with caution and only when other measures have failed.

Coagulation studies in haemophilic patients taking oral contraceptives.

Coagulation studies were performed on haemophilic patients during a controlled trial of oral contraceptive therapy. Treatment with a combined oestrogen-progestogen preparation was associated with a significant rise in the factor VII-X complex. This change was not observed during treatment with progestogen alone. The highest levels of factor IX and fibrinogen and the lowest levels of factor X were observed during the first period of the trial but these effects were independent of the type of treatment. The results suggest that the effects of oral contraceptives on blood coagulation in haemophilic males are similar to those observed in normal females and that the changes are due to the oestrogenic component.

A controlled trial of glycopyrronium and l-hyoscyamine in the long-term treatment of duodenal ulcer.

A controlled single-blind trial has been carried out to determine the value of long-term anticholinergic therapy in duodenal ulcer. Of 106 male patients with symptomatic and radiologically proven duodenal ulcer admitted to the trial, 91 completed the study. Patients were divided randomly into three groups. They received either glycopyrronium, or 1-hyoscyamine in a sustained-release form, or inert tablets for one year. Progress was judged on the basis of frequency and severity of symptoms, monthly assessments by patients, antacid consumption, and radiology. By all criteria, glycopyrronium and 1-hyoscyamine were not significantly superior to placebo. Symptomatic improvement, both subjective and objective, occurred in approximately 80% of all patients during the year of observation; there was no significant difference between the groups.

Gastric acid secretion in patients with duodenal ulcer treated for one year with anticholinergic drugs.

Ninety patients with duodenal ulcer, divided randomly into three groups, were treated continuously for one year with either glycopyrronium, 1-hyoscyamine (as a sustained-release preparation) or inert tablets. Dosage with active tablets was so adjusted that the patient experienced definite but tolerable side-effects. Basal and maximal gastric acid secretion were measured immediately before and one week after cessation of treatment. There was no significant change in the means of these measurements in patients who received placebo or 1-hyoscyamine. In those given glycopyrronium, mean basal output was significantly increased. Mean maximal acid output in this group fell, but not significantly.Individual measurements of maximal acid output showed quite marked fluctuations in all groups. It is concluded that spontaneous changes in parietal cell mass may occur in patients with duodenal ulcer, and that prolonged anticholinergic therapy does not reduce parietal cell mass.
