The therapeutic effect of methyl-salazosulphapyridine versus salazosulphapyridine in active ulcerative colitis. A double-blind controlled trial.

In an attempt to improve the ratio between therapeutic effect and side effects of salazosulphapyridine (SASP), methyl-salazosulphapyridine (methyl-SASP) was compared with SASP in a randomized controlled double-blind trial, without cross-over, in patients with active ulcerative colitis. The patient group comprised 53 patients. The daily doses were 1 g SASP x 3 and 125 mg methyl-SASP x 3. The methyl-SASP group comprised 26 patients, the SASP group 27 patients. The treatment period was 4 weeks. Applying clinical symptoms (bowel movements, registered by the patients on special charts), clinical condition (assessed by the patient), proctoscopic signs, and registration of side effects, it is concluded that methyl-SASP had an effect on ulcerative colitis indistinguishable from that of SASP. The rate of side effects was significantly less in the methyl-SASP group. The blood concentrations of SASP, methyl-SASP, sulphapyridine, and methyl-sulphapyridine were estimated at start during, and at the end of the trial. The methyl-SASP concentration was on an average twice as high as that of SASP, and the methyl-sulphapyridine on an average 1/13 of sulphapyridine, the differences being significant. It is concluded that methyl-SASP presents an improvement in the effect/side effect ratio when dealing with symptomatic ulcerative colitis. The discrepancy between the outcome of the present trial and the lack of effect in a controlled trial on the relapse-preventing effect of methyl-SASP is at present unexplained. A type II error in the present trial (or a type I error in the prophylactic one) is a possibility, or the patient-group selected for the present trial had a spontaneously benign course, cases demanding prednisone or colectomy having been excluded.

A prospective comparative study of clinical and pathological characteristics in Icelandic and Danish patients with gastric ulcer, duodenal ulcer, and X-ray negative dyspepsia. II. Histological results.

The occurrence of gastritis in antral and body mucosa is compared in an Icelandic and a Danish group of patients with gastric ulcer, duodenal ulcer, and X-ray negative dyspepsia. In all 93 Icelandic and 88 Danish patients were examined. All signs of antral gastritis were more frequent in Icelandic than in Danish patients, but only the incidence of superficial inflammation and decreased mucus content in surface and crypt epithelium differed significantly. In body mucosa pseudopyloric metaplasia was more frequent in Iceland and occurred equally freqeuntly in all three diseases. A statistically significant correlation was found between macroscopic gastritis and occurrence of antral superficial inflammation and between smoking and superficial inflammation and decreased mucus content in the pyloric biopsy specimen. The presence of histological gastritis was not correlated to the intake of alcohol and salicylic acid, nor to the presence of pain at the time of investigation.

The leucocyte chemotactic function in patients with ulcerative colitis.

The intermittent course of ulcerative colitis could hypothetically be be caused by fluctuations of the patients' natural systems of resistance. To evaluate this hypothesis the chemotactic function of leucocytes in ulcerative colitis patients has been investigated. The patient group comprised 59 patients, 24 men and 35 women. All activity stages were represented. The control group comprised 25 normal subjects, 10 men and 15 women. The chemotactic reaction was investigated in a double chamber with a cellulose-ester-micropore filter with a pore size of 3 mum as a diaphragm in which the migration takes place. The variable applied was the ratio between the number of cells 50 mum down in the filter and at the surface, calculated as a chemotactic Index. Casein was used as chemotactic agents. The corrected chemotactic was defined as the difference between stimulated and unstimulated Chemotactic Index. The chemotactic as well as the corrected chemotactic response of leucocytes from ulcerative colitis patients was significantly lower than in control subjects. The subgroup, active ulcerative colitis,showed the lowest corrected Chemotactic Index, whereas the unstimulated Control Index was significantly higher than in normal subjects. The results did not correlate with treatment. The investigation has shown that leucocytes in active ulcerative colitis cases have a high spontaneous mobility, whereas their chemotactic function after stimulation is significantly subnormal. Further investigation is needed to demonstrate whether this phenomenon plays a major role in the pathogenesis of ulcerative colitis.

Leucocyte migration test with autologous colonic mucosa as antigen in patients with ulcerative colitis.

The leucocyte migration agarose technique (LMAT) was applied in a study of the migration of peripheral leucocytes in 16 patients with ulcerative colitis using three different autologous types of tissue as antigen: rectal mucosa, skin and buccal mucosa. In all cases the migration indices were within normal limits, and they did not differ from a group of control patients suffering from peptic ulcer, irritable colon or haemorrhoidal tumours. The present study does not support the theory of cellular hypersensitivity against colonic mucosa in patients with ulcerative colitis.

A prospective comparative study of clinical and histological characteristics in Icelandic and Danish patients with gastric ulcer, duodenal ulcer, and X-ray negative dyspepsia. I. Design and clinical features.

Iceland (IS) and Denmark (DK) are ethnically, culturally, and economically closely related Nordic countries, but gastric cancer is much more frequent in Iceland, and other differences in the occurrence rates of gastric diseases are also suspected. Therefore a cooperative study was initiated comparing Icelandic and Danish patients with gastric ulcer (GU), duodenal ulcer (DU), and X-ray negative dyspepsia (XND) as regards clinical features, external factors of possible importance for gastritis and cancer, gastroscopic appearance, and histological gastric mucosal changes. The project lasted one year and comprised 93 Icelandic and 88 Danish patients. A large number of comparisons showed a high degree of similarity between Icelandic and Danish patients. Significant differences were found in tobacco consumption (DK greater than IS), duration of symptoms in XND (IS greater than DK), whereas the positon ratio of GU (IS less than DK) and acetylsalicylic acid consumption (DK greater than IS) showed non-significant trends. Significant difference was found between the occurrence of diffuse macroscopic changes of the gastric mucosa (IS greater than DK), which corresponds to the histological differences to be described in a subsequent article.

The constipating effect of diphenoxylate (Retardinr) in ulcerative colitis. A double-blind controlled trial.

A double-blind study of 20 patients with ulcerative colitis during treatment with diphenoxylate 5 mg three times daily and placebo is reported. There were two treatment periods of 14 days each, with cross-over technique and randomized sequence. Test variable for constipating effect was the mean number of defaecations per day. The criterion for inclusion of patients was the presence of 4 or more daily bowel movements; 2 patients did not complete the investigation. Significant difference (p less than 0.01) in constipating effect between diphenoxylase and placebo was demonstrated both during a period of 12 days and a period of 6 days (Tables II and III). The average number of bowel movements were reduced by 0.7 and 1.3 per day respectively. Side-effects during treatment with diphenoxylate were seen in 53% (Table III) with significant difference against placebo (p less than 0.05). On the basis of the small absolute reduction of defaecation frequency side-effects, it is concluded that diphenoxylate has no place in the routine treatment of ulcerative colitis.

The small intestinal disaccharidase activity in ulcerative colitis.

In 12 patients suffering from ulcerative colitis the small-intestinal disaccharidase activity has been determined during an acute exacerbation of the disease as well as after remission. The lactase activity was significantly lower during the acute stage. No case of transitoric lactose malabsorption was found.

The incidence of lactose malabsorption in ulcerative colitis.

120 Danish patients with ulcerative colitis, admitted consecutively to a Department of Gastroenterology, were investigated for lactose malabsorption. The prevalence was 9.2 percent, which is not significantly higher than that in a mixed Danish gastroenterological material, There was no difference in distribution according to age and sex, and the incidence was not correlated to the severity of the ulcerative colitis. The possible reasons for the wide variation in the incidence of lactose malabsorption in materials of patients with ulcerative colitis are discussed, and it is concluded that the main cause must be that the materials with the highest incidence include patients of races and ethnic groups in which lactose malabsorption is a common finding.
