    Notes: Summary The efficacy and safety of mifentidine 20 mg at night, a new, potent, long-acting H2-receptor antagonist, has been compared with ranitidine 300 mg at night in 60 patients with acute duodenal ulcer, in a randomized double-blind study. Antacid tablets were allowed as additional treatment for pain relief. The treatment lasted for 4 weeks. After 4 weeks of treatment the healing rate was similar; amongst the patients who completed the treatment, healing was 68% for mifentidine, 63% for ranitidine, and on intention-to-treat analysis, healing in both groups was 63%. Pain relief and antacid consumption were similar in both groups. Clinically significant adverse effects were not detected and any changes in laboratory values were minimal, clinically insignificant and reversible. Mifentidine appears to be an effective and safe once-a-day treatment for acute duodenal ulcer disease.

    Notes: This was a randomized, double-blind, multicentre, short-term study comparing ranitidine and nizatidine at the standard dosages of 300 mg at bedtime. In 49 centres in Italy, all peptic ulcer patients aged over 65 years and with endoscopically documented acute disease were considered eligible for the study. Clinical check-ups were repeated every 3 weeks, while the endoscopic and biochemical assessments were scheduled at 6 and (in unhealed patients) 12 weeks. Statistics: chi-squared test, Fisher's exact test, Student t-test for unpaired data. The study included 170 duodenal ulcer and 75 gastric ulcer patients. Of these, 83/17 duodenal ulcer and 38/75 gastric ulcer patients were treated with nizatidine 300 mg and the remainder with ranitidine 300 mg. The groups were well-matched for common clinical data. Eight patients dropped out. Healing rates at 6 and 12 weeks were 81.9% and 91.5% for nizatidine-treated duodenal ulcer patients versus 78.1% and 94.2% for ranitidinetreated duodenal ulcer cases (P: N.S.); 6 and 12-week healing rates were 76.3% and 89.5% for nizatidinetreated gastric ulcer patients versus 67.6% and 83.8% for ranitidine-treated gastric ulcer patients (P: N.S.). No slow healing risk factors were found. Only minor adverse events were registered. In conclusion: ranitidine 300 mg and nizatidine 300 mg both proved effective and safe in the treatment of acute peptic ulceration in the elderly.

    Notes: A 24-week, double-blind, randomized study at 13 centres compared the efficacy and safety of 20 mg famotidine nocte and 150 mg ranitidine h.s. for the prevention of duodenal ulcer recurrence. All participants had been successfully treated for an acute duodenal ulcer with 40 mg famotidine nocte. Patients were endoscoped at baseline and at 24 weeks, unless symptoms warranted earlier examination: of the 208 patients enrolled, 86 who received famotidine and 84 who received ranitidine met all protocol criteria and were considered evaluable.Intention to treat and per protocol analyses showed non-significant trends in favour of famotidine (P= 0.44 and 0.16, respectively). During the 24-week observation period, 16.3% of the famotidine group and 25% of the ranitidine group had an ulcer recurrence (95% CI of percentage difference –0.22 + 0.04). At 24 weeks, relief of day and night pain was reported by 81.2% and 91.8% of the famotidine-treated patients, respectively. The corresponding figures in the ranitidine group were 73.5% and 85.5%.No laboratory abnormalities related to the study-drugs were noted and only two drug related (possibly or probably) adverse experiences were reported, both in the famotidine group. The data from this study therefore, supports the conclusion that the efficacy of 20 mg famotidine nocte is comparable to that of ranitidine in preventing duodenal ulcer recurrence, with comparable tolerability for long-term therapy.

    Notes: Aim : To evaluate clinical and psychological status of adults with childhood diagnosis of coeliac disease who were re-exposed to gluten after only a few years and now on a gluten-containing diet, compared with adults with recent diagnosis of coeliac disease, and adults who remained on gluten-free diet after childhood diagnosis.Methods : A total of 195 adults with a biopsy suggestive of coeliac disease in childhood, who either had adhered to a gluten-free diet for at least 1 year after diagnosis and now are either on gluten-free diet (n = 110) or on gluten-containing diet (n = 85), and adults with newly diagnosed coeliac disease (n = 165) underwent a medical check-up.Results : Body mass index and main laboratory indices were statistically different among groups (lowest in never on gluten-free diet, highest in gluten-free diet). The lowest average levels of bone mineral density were found among never on gluten-free diet patients. Prevalence of autoimmune disorders was increased in never on gluten-free diet when compared with the transient gluten-free diet and gluten-free diet groups. Histology revealed villous subatrophy in all patients of never on gluten-free diet group, in 39 of 110 patients of gluten-free diet and in 84 of 85 of transient gluten-free diet groups. Herpetiform dermatitis was found in three patients of gluten-free diet, three of transient gluten-free diet and three of never on gluten-free diet. Dental enamel defects were found in 15 patients of transient gluten-free diet, 43 of never on gluten-free diet and in zero of the gluten-free diet group. Pregnancy outcome was not significantly different between the two groups, but neonatal weight was lower and breast feeding was shorter in the never on gluten-free diet group. Sexual habits, alcohol intake and cigarette smoking were significantly different in the never on gluten-free diet group when compared with the other two groups.Conclusion : Gluten withdrawal in childhood partly protects coeliac adults from clinical and behavioural effects of gluten sensitivity.

    Notes: Background : Small bowel bacterial overgrowth is common in Crohn's disease but its treatment is not clearly defined. Metronidazole and ciprofloxacin are effective antibiotics in active Crohn's disease.Aim : To investigate the efficacy of metronidazole and ciprofloxacin in the treatment of bacterial overgrowth in patients with Crohn's disease.Patients and methods : We performed the lactulose breath test in 145 consecutive patients affected by Crohn's disease. Patients positive to the lactulose breath test underwent a glucose breath test to confirm the overgrowth. These patients were randomized in two treatment groups: metronidazole 250 mg t.d.s. (Group A) and ciprofloxacin 500 mg b.d. (Group B), both orally for 10 days. The glucose breath test was repeated at the end of treatment. The clinical outcome after therapy was also recorded.Results : Bacterial overgrowth was present in 29 patients (20%). Breath test normalization occurred in 13 out of 15 patients treated by metronidazole and in all 14 patients treated by ciprofloxacin (P = ns). In both groups antibiotic treatment induced an improvement of intestinal symptoms: bloating (Group A 85% and Group B 83%), stool softness (44% and 50%), and abdominal pain (50% and 43%).Conclusions : Small bowel bacterial overgrowth is a frequent condition in Crohn's disease which can be effectively treated by metronidazole or ciprofloxacin.

    Notes: Abstract. The aim of this study was to evaluate the accuracy of enteroclysis in the diagnosis of Crohn's disease of the small bowel in a group of consecutive patients. From January 1992 to December 1995, 165 patients with suspected Crohn's disease of the small bowel presented to our institution for enteroclysis. In 14 patients up to three enteroclysis exams were performed. Most patients (78 %) underwent colonoscopy and retrograde ileoscopy. In the remaining patients clinical follow-up was used as gold standard. In 79 patients no radiographic abnormalities were found. Sixty-one patients (40 men and 21 women; mean age 34.2 years) had a radiological diagnosis of Crohn's disease. This involved the terminal ileum in 39 patients (64 %) either alone (n = 25) or in association with the pelvic ileum (n = 14). In 12 of these patients retrograde ileoscopy was not feasible. Twenty-one patients underwent surgery. In 4 patients pathology revealed diseases other than Crohn's. These patients had all ileocecal diseases (tuberculosis = 2; non-Hodgkin's lymphoma = 1; adenocarcinoma = 1). One false-negative result was observed. Overall, enteroclysis showed a sensitivity of 98.2 % and a positive predictive value of 93.4 %. Enteroclysis is a sensitive technique in evaluating both the extent and the severity of small bowel involvement in Crohn's disease, although the overlap of radiographic findings may hamper its accuracy when the disease is confined to the ileocecal area.

    Notes: Abstract Gastric mucosal cell migration and proliferation are crucial events in the repair of gastric mucosal erosions. This study was designed to test the hypothesis that the H2 blockers roxatidine and ranitidine might stimulate migration and proliferation of gastric mucous cells derived from a human well-differentiated gastric adenocarcinoma cell line (MKN 28 cells)in vitro, in conditions independent of systemic factors and of acid inhibition. Confluent monolayers of MKN 28 cells were wounded with a razor blade and were then incubated with roxatidine or ranitidine. The number of cells migrating to the damaged area was determined 24 hr later. Cell proliferation was assessed by means of [3H]thymidine uptake and cell counts after incubation with roxatidine or ranitidine. Neither H2 antagonist significantly stimulated cell migration. On the other hand, cell proliferation was dose-dependently and significantly enhanced by incubation with roxatidine and ranitidine. Exogenous administration of TGF-α significantly stimulated MKN 28 cell division. However, incubation with roxatidine or ranitidine did not increase the steady-state mRNA expression of TGF-α or EGFR as assessed by northern blot analysis. Based on thesein vitro findings, we postulate that the ulcer healing effect of these H2 antagonistsin vivo might be due in part to stimulation of gastric mucosal cell proliferation.

    Notes: Abstract The present multicenter double-blind placebo-controlled trial evaluates the therapeutic effectiveness of small-volume daily doses of an isosmotic polyethylene glycol (PEG) electrolyte solution in the treatment of chronic nonorganic constipation. After a complete diagnostic investigation, patients still constipated at the end of a four-week placebo-treatment run-in period were enrolled and randomized to receive either placebo or PEG solution 250 ml twice a day for the following eight weeks. Patients were assessed at four and eight weeks of treatment, and they reported frequency and modality of evacuation, use of laxatives, and relevant symptoms daily on a diary card. Oroanal and segmental large-bowel transit times were assessed with radiopaque markers during the fourth week of the run-in period and the last week of the treatment period. During the study period, dietary fiber and liquids were standardized and laxatives were allowed only after five consecutive days without a bowel movement. Of the 55 patients enrolled, five dropped out, three because of adverse events and two for reasons unrelated to therapy; another two were excluded from the efficacy analysis because of protocol violation. Of the remaining 48 patients (37 women, age 42±15 years, mean±sd), 23 were assigned to placebo and 25 to PEG treatment. In comparison to placebo, PEG solution induced a statistically significant increase in weekly bowel frequency at four weeks and at the end of the study (PEG: 4.8±2.3 vs placebo: 2.8±1.6;P〈0.002) and a significant decrease in straining at defecation (P〈0.01), stool consistency (P〈0.02), and use of laxatives (P〈0.03). Oroanal, left colon, and rectal transit times were significantly shortened by PEG treatment. There was no difference between controls and PEG-treated patients as far as abdominal symptoms and side effects were concerned. In conclusion, PEG solution at 250 ml twice a day is effective in increasing bowel frequency, accelerating colorectal transit times, and improving difficult evacuation in patients with chronic nonorganic constipation and is devoid of significant side effects.

    Notes: Abstract The aim of the present study was to determine whether blood group O and nonsecretor status are associated with gastric hyperacidity. Total output of gastric acid after maximal histamine stimulation was evaluated in 515 patients—220 males and 295 females—aged 20–50 years, with and without a familial history of duodenal ulcer. All of them were free of gastroduodenal disease. HCl output was found to be significantly higher in patients of blood group O than in those of A, B, and AB, irrespective of family history of duodenal ulcer. Furthermore HCl output was significantly higher, when blood group O was concerned, in nonsecretors than in secretors. In groups A, B, and AB there were no differences between secretors and nonsecretors. These results support the hypothesis that increased levels of acid secretion may explain partially the high incidence of duodenal ulcer among subjects possessing one or both the phenotypic traits—blood group O and nonsecretor.
