Reducing overnight secretion of acid to heal duodenal ulcers. Comparison of standard divided dose of ranitidine with a single dose administered at night.

This study was undertaken to assess the clinical usefulness of a single nighttime dose of ranitidine in the short-term healing of duodenal ulcer. One hundred and nine patients with endoscopically diagnosed duodenal ulcer were randomly allocated to treatment with ranitidine, either 150 mg twice daily or 300 mg as a single nighttime dose for four weeks, in a prospective double-blind, double-placebo trial. Of the 102 patients who completed the study, 48 of 57 (84 percent) healed endoscopically on ranitidine 150 mg twice daily, and 43 of 45 (96 percent) healed on 300 mg at nighttime (Mantel-Haenszel test without continuity correction: X2 = 2.9, p = 0.09). One patient treated with ranitidine 150 mg twice daily had a transient episode of cholestatic hepatitis that did not necessitate stopping the drug; in this patient the ulcer healed after 28 days of treatment. There were no other unwanted effects in either group and no significant abnormal biochemical or hematologic changes. This study shows that ranitidine 300 mg given as one nighttime dose is as safe as 150 mg twice daily, and equally as effective. Three hundred milligrams at night appear to confer protection against the adverse effect of smoking in ulcer healing.

Ranitidine 150 mg twice daily vs 300 mg nightly in treatment of duodenal ulcers.

102 patients with endoscopically proven duodenal ulcers were randomly allocated to treatment with ranitidine either 150 mg twice a day or 300 mg every evening for 4 weeks in a prospective double-blind study. The two groups were similar. 48/57 (84%) healed on ranitidine 150 mg twice daily and 43/45 (96%) healed on 300 mg every evening (p = 0.9)--that is, ranitidine 300 mg as a single night time dose is as effective as 150 mg twice daily. The results also indicate the importance of overnight gastric acidity in the pathogenesis of duodenal ulcers.

Comparison of ranitidine and cimetidine maintenance treatment of duodenal ulcer.

Sixty-one patients with healed duodenal ulcer were studied during a 12-month maintenance trial with either 150 mg ranitidine at night or 400 mg cimetidine at night. Recurrences were determined at endoscopy after 6 and 12 months of treatment or because of symptomatic relapse. Ulcers recurred in 7 of 28 patients receiving ranitidine and in 8 of 33 patients receiving cimetidine. No serious side effects were encountered.

Comparison of twice-daily ranitidine with standard cimetidine treatment of duodenal ulcer.

One hundred and three outpatients with endoscopically diagnosed duodenal ulcer were randomly allocated to treatment with either cimetidine 200 mg tds and 400 mg nocte, or ranitidine 150 mg bd for four weeks. The endoscopists were not aware of the treatment and took no part in the clinical management. On completion of treatment ulcers had healed in 43 of 51 (84%) patients given cimetidine and in 40 of 52 (77%) patients given ranitidine. There were no serious unwanted effects in either treatment group. The results show no significant difference between healing rates after four weeks of standard cimetidine therapy or ranitidine 150 mg bd.

Controlled comparison of cimetidine and carbenoxolone sodium in gastric ulcer.

Fifty-four outpatients with endoscopically diagnosed benign gastric ulcer were allocated at random to treatment with either cimetidine 800 mg daily for six weeks or carbenoxolone sodium 300 mg daily for one week then 150 mg daily for five weeks. Ulcers were reassessed by endoscopy at the end of the trial. The endoscopist was unaware of the treatment and did not take part in the clinical care of the patients. Twenty-one of the 27 patients (78%) given cimetidine and 14 of the 27 (52%) given carbenoxolone had healed ulcers. Symptomatic response occurred earlier with cimetidine but was not significantly better. Unwanted effects were more common in the carbenoxolone group: 12 patients developed hypokalaemia, four of whom needed oral potassium supplements. The results suggest that histamine H2-receptor blockade is at least as effective as carbenoxolone sodium for benign gastric ulcer and produces fewer side effects.

Cell-mediated immune responses in chronic liver diseases.

Studies of the cell-mediated response to liver antigens, using the leucocyte migration test, in 163 patients with various liver disorders showed that abnormal responses were almost confined to active chronic hepatitis (53% abnormal), primary biliary cirrhosis (64%), and cryptogenic cirrhosis (29%). The test was also abnormal in five out of seven patients with jaundice due to drug hypersensitivity and in one patient with acute infectious hepatitis at a time when mitochondrial antibodies were present in the serum. More of those with active chronic hepatitis on prednisone or azathioprine had normal tests than of those who were untreated, and in 8 out of 10 examined serially during therapy there was an accompanying improvement in leucocyte migration. Abnormal responses to salivary gland or kidney antigens were also found in nearly half of those with features of Sjögren's syndrome or renal tubular acidosis as part of a multisystem involvement-this, though occurring in cryptogenic cirrhosis, was found with greater frequency in active chronic hepatitis and primary biliary cirrhosis. These cell-mediated immune responses, perhaps triggered by the initial damage to the liver from viral or other agents, may be responsible both for the perpetuation of the liver disease and, because of common surface antigens, for the damage to other organs.

Renal tubular acidosis and autoimmune liver disease.

Forty-two patients with autoimmune liver disease have been investigated. Renal tubular acidosis was detected in 60% of the patients with primary biliary cirrhosis, in 30% with active chronic hepatitis, and in one out of seven cases with cryptogenic cirrhosis. The presence of the defect of renal acidification was not related to the level of plasma potassium, copper, or total globulin, nor to the pattern of immunological abnormalities detected in the serum. It is suggested that autoimmune liver disease and renal tubular acidosis may be part of a systemic disorder in the pathogenesis of which immunological mechanisms are involved.

Multiple immunological abnormalities in a family.

The family of a woman with multiple autoimmune diseases has been investigated. Clinical evidence of an autoimmune disorder was detected in two relatives, and five others had serological and immunoglobulin abnormalities. It is suggested that there is an inherited predisposition to develop immunological abnormalities, and that a number of associated autoimmune diseases may develop in families in which this occurs.
