To determine whether circulating immune complexes are present in the sera of patients with inflammatory bowel disease (IBD), a 125I-Clq binding assay was performed. Of the 55 IBD serum samples tested, the 24 ulcerative colitis samples demonstrated significant binding (33.1 +/- 8.3%, p = 0.02), whereas the 31 Crohn's samples bound essentially normal amounts (29.2 +/- 7.4%). A positive control group consisting of 27 patients with rheumatoid arthritis was also studied. Sera from 4 patients wiht IBD and colonic cancer when tested, bound 40.2 +/- 8.0% of the available 125I-Clq, while 10 patients with previous colectomies and ileostomies gave results similar to those of 15 healthy controls and 11 patients with irritable colon.

A case is described of an unusual combination of polypois and inflammatory bowel disease of a granulomatous type. A striking feature is the complexity of the polypoidal lesions. The relationship between these lesions and the granulomatous colitis which is probably a variant of Crohn's disease is discussed.

Jejunal mucosal function and structure was examined in 31 patients with ulcerative colitis and 29 patients with Crohn's disease with ileal, ileocolonic or colonic involvement; A significant reduction of the specific activity of disaccharidases (lactase, sucrase and trehalase) in jejunal mucosal homogenate occurred in patients with inflammatory bowel disease. Similarly, alkaline phosphatase was reduced in ulcerative colitis. Several dipeptidases such as glycyl-leucine, leucyl-glycine, glycyl-glycine and valyl-proline hydrolase activities were lower in patients with inflammatory bowel disease than in controls. Histological changes in jejunal mucosal biopsies occurred in 71% of patients with ulcerative colitis and 61% with Crohn's disease. These changes ranged from mild abnormalities of villus architecture to marked reduction of villus height. Most patients with a reduction in mucosal enzymes had concommitant morphological changes in jejunal mucosal biopsy. The results of this study indicate that functional and structural abnormalities of the jejunal mucosa frequently occur in patients with inflammatory bowel disease without radiologic evidence of proximal small bowel involvement.

Four new cases of chronic inflammatory bowel disease in a series of 135 adult patients with Turner's syndrome observed over an average period of 11 years are reported. The diagnosis in 2 of the patients was ulcerative colitis; the other 2 had clinical and histological features consistent with a diagnosis of Crohn's disease. The incidence is considerably higher than any reported frequency of new cases of inflammatory bowel disease in the general population. Previously reported cases are described and attention is drawn to the severity of the bowel disorder. An apparent association with a karyotype abnormality which includes a structurally abnormal X chromosome is noted.

Vaginoplasty was used in a consecutive series of 45 patients undergoing rectal excision for neoplastic and inflammatory bowel disease. Forty-three patients achieved primary perineal healing and none developed a persistent perineal fistula. One patient with Crohn's disease developed a perianal fistula a year after operation but healing occurred after minor surgery. Another developed a pre-sacral abscess 9 years after operation; spontaneous discharge into the vagina occurred.

Inflammatory bowel disease is generally assumed to be rare among negroes and Indians. Over 10 years 34 cases of ulcerative colitis and 14 cases of Crohn's disease were seen in one medical and one surgical unit in Port-of-Spain, Trinidad. Twenty-six patients were Negroes, 18 were Indians, three were of mixed race, and one was Caucasian. In many of these patients the disease was extensive and several of those with Crohn's disease suffered severe complications. The assumption that inflammatory bowel disease is rare among West Indians of African and Indian origin therefore seems to be wrong.

Levels of the serum complement components, C3 and C4, in patients with Crohn's disease, ulcerative colitis, and miscellaneous gastrointestinal disorders were compared with those of normal blood donors. Significant increases of both components were found in all three patient groups, the highest being in patients with Crohn's disease. Generally, levels of C3 and C4 were lower in patients with inactive rather than active Crohn's disease and ulcerative colitis. These results provide some evidence in support of an immunological basis for inflammatory bowel disease. However, in view of the frequent elevation of C3 and C4 in other gastrointestinal diseases, it is equally possible that the complement components are behaving as acute phase proteins.

In 18 patients with ulcerative colitis and in 8 with Crohn's disease two tests were performed simultaneously: a) the leukocyte migration inhibition test using Kunin antigen, and b) titration of serum antibodies against this antigen. Leukocyte migration was studied by the agarose plate technique. At the concentration of 25 microgram/ml, Kunin antigen inhibited migration in five cases of ulcerative colitis and in one with Crohn's disease. This phenomenon was not observed in any of 33 control subjects. All patients in whom leukocyte migration was inhibited were in the active phase of the disease. Titers of antibodies against Kunin antigen were determined by the passive hemagglutination test in an expended group of patients comprising 61 with Crohn's disease. The antibody titer, expressed as the geometric mean of hemagglutinin titers, was nearly three times as high in patients as in 324 healthy controls. The titers were not correlated either with clinical activity of both diseases or with the results of the leukocyte migration inhibition test. The significance of these findings is discussed in the light of other data indicating that Kunin antigen plays a role in the pathogenesis of inflammatory bowel disease.

In 45 patients with inflammatory bowel disease (9 with Crohn's disease and 36 with ulcerative colitis) and associated liver disorders, increased liver copper content (above 100 microgram/g dry weight) was found in 14 (31%). These patients represented about 50% of the patients with either biliary cirrhosis or pericholangitis. Four of the patients had levels regarded as compatible with hepatolenticular degeneration (greater than 250 microgram/g dry weight). In patients with chronic active hepatitis or non-specific changes in liver tissue, normal levels were found. The patients with Crohn's disease also had normal levels. Plasma ceruloplasmin was normal or increased in all. Determination of urinary copper output gave little diagnostic information. Alkaline phosphatases were markedly increased in most of the patients with increased liver copper concentration. In patients with ulcerative colitis and enhanced alkaline phosphatases, elevated liver copper content should be suspected and chelation therapy should be considered.

Thirty-nine patients with ulcerative colitis and 35 with Crohn's disease have been investigated for evidence of reaginic hypersensitivity and compared with control subjects. There was no difference in the frequency of a personal or family history of atopy or in serum IgE levels. Similarly, no overall difference was noted in prick test responses to 21 allergens. However, further analysis of prick test responses showed that patients with inflammatory bowel disease responded more frequently to food allergens. This was highly significant when compared with healthy controls (p less than 0.001). The relevance of this finding to the aetiology of inflammatory bowel disease is discussed.
