Variations in plasma protein concentrations in individuals with ulcerative colitis: analytical and biological factors.

Eight plasma proteins were determined in specimens taken every second day during a 14 day period from eleven patients with acute ulcerative colitis. The intra-individual variations in the concentrations of albumin, orosomucoid, haptoglobin, IgG, IgA, IgM and complement factors C3 and C4 were larger than expected in normal persons. A two-way analysis of variance was applied to the normalized protein values to estimate to what extent the observed variations could be explained by analytical errors and the influence of biological factors general to all proteins, such as changes in plasma volume and distribution between plasma and extravascular space. In half the non-operated patients the changes in all proteins could be explained by the above mentioned variations. The individual variations seen in the concentrations of haptoglobin, C4 and IgM occurred at random compared to the clinical state of the disease. Only the operated patients showed a more systematic sequence of protein changes.

The relapse-preventing effect of methyl-salazosulphapyridine compared to salazosulphapyridine during long-term treatment of ulcerative colitis. A double-blind controlled trial.

In an attempt to improve the relapse-preventing effect of salazosulphapyridine (SASP) and to encircle the part of the molecule essential for therapeutic actin, methyl-SASP was compared to SASP in a controlled double-blind trial without cross-over. The patient group comprised 33 patients with ulcerative colitis who had been symptom-free for 1--6 months on continuous treatment with SASP (on an average 2 g daily). The daily doses were SASP 1 g X 3 and methyl-SASP 125 mg x 3. Thirty patients completed the trial, 14 on SASP and 16 on methyl-SASP. Applying clinical criteria, the relapse rate after 6 months was 0.14 in the SASP group and 0.69 in the methyl-SASP group. The difference is highly significant. The blood concentrations of SASP, methyl-SASP, sulphapyridine (SP), and methyl-sulphapyridine (methyl-SP) were measured after 3 and 6 months. The methyl-SASP concentration was on an average twice as high as that of SASP, and the methyl-SP on an average 1/10 of SP (the differences are significant). It is concluded that whereas SASP showed a relapse-preventing effect in ulcerative colitis in this study comparable to that previously reported, the effect of methyl-SASP was only comparable to that of placebo, and the active substance in SASP does not seem to be unsplit SASP.

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.

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.
