Altogether, 138 patients were included in a study aimed at evaluating the effect of cisapride on healing and relapse of oesophagitis shown endoscopically. In the first phase of the study cisapride was given in an open fashion at 10 mg four times a day for 8 to 16 weeks, and healing was obtained in 69% of patients. Healing occurred later in patients with grades II to IV oesophagitis. The total score for reflux symptoms decreased by 67%. Eighty of the healed patients were included in the second phase. They were randomly assigned to double blind treatment with either cisapride 10 mg (n=37) or placebo (n=43) twice a day. Control endoscopy was performed when symptoms recurred or at the end of the six month trial. The cumulative percentage of patients in remission was higher (p=0.06, survival analysis) in the cisapride group than in the placebo group, the relapse rates being 20% and 39%. The duration of remission tended to be longer in patients with a lower initial degree of oesophagitis. Adverse effects were no more frequent with cisapride than with placebo. In conclusion, cisapride is efficacious in healing oesophagitis, and, unlike other gastrointestinal prokinetic drugs or low dose cimetidine (400-800 mg daily) or ranitidine (150 mg daily), it may prevent relapse of oesophagitis.

Summary:Five hundred and seven elderly hypertensive patients were followed for 1 year, 371 for 2 years and 270 for 3 years in a double-blind, randomized, controlled trial in which they received either placebo or 25-50mg hydrochlorothiazide and 50-100mg of triamterene daily. One third of the active treatment group also received 250 mg to 2 g methyldopa daily. After 1 year the active treatment group had an average increase in fasting blood sugar of 2.5 mg/dl compared with an average fail of 1.4 mg/dl in the placebo group (P = 0.01). The increase "M blood sugar 1 hour and 2 hours after 50 g oral glucose tended to be greater in the actively treated group but these increases did not achieve statistical significance. The effects of diuretic treatment were established after one year and did not increase further over the next 2 years. Overall there was an increase in fasting blood sugar of 5 mg/dl in the active treatment group which occurred mainly in the first year.The hyperglycaemic effect ofdiuretics appeared to be partly or wholly related to potassium loss since, in both groups, impairment of glucose tolerance was most marked in those in whom serum potassium decreased. The measures of blood sugar were also positively related to systolic pressure before and after treatment.The following centres collaborate in the EWPHE trial:
