A prospective evaluation of the activity of the complement system was undertaken in 32 patients at the time of diagnosis of inflammatory bowel disease, before the onset of therapy. Serum classical pathway components and function were normal, while significant abnormalities of the alternative pathway were found. Depressions of serum properdin and properdin convertase were noted in association with diminished consumption of C3--C9 after reaction with cobra venom. These abnormalities of alternative pathway integrity were most significant in regional enteritis and in ulcerative colitis with extraintestinal complications. Sequential studies extending into clinical remission revealed resolution of all significant abnormalities.

Recurrent retinal branch artery occlusions, carotid thromboembolism, cerebral venous thrombosis, transient brainstem ischemia, and massive brainstem and cerebral infarction complicated the course of inflammatory bowel disease in 5 patients. Three patients had ulcerative colitis and 2 had regional enteritis. The usual risk factors for stroke were absent. Neuropathological examination in 1 patient showed in situ thrombosis of small cerebral and brainstem arteries and veins. Coagulation studies showed thrombocytosis, short partial thromboplastin times, and elevation of fibrinogen and Factor VIII levels. Platelet counts and coagulation factors returned toward normal after control of intestinal inflammation in each of the 4 surviving patients. Inflammatory bowel disease can be accompanied by a hypercoagulable state that predisposes to stroke.

During the past 3 yr, 17 patients with chronic ulcerative colitis and 6 with Crohn's disease who had severe rectal and colonic involvement underwent excision of the rectal mucosa without removal of the rectal muscle in combination with total colectomy and cutaneous ileostomy as a 1- or 2-stage procedure. This operative technique has cured each of the patients of their primary colonic and rectal disease and has obviated many of the unpleasant complications that often occur after total proctectomy, such as impotence, prolonged perineal drainage, and bladder dysfunction. The operation has the further advantages of lower operative blood loss, shorter operative time, and earlier safe ambulation. On the basis of the favorable experience with mucosal proctectomy, sphincterotomy, and perineal drainage in 23 patients, none of whom experienced major complications, we believe that this operation warrants further clinical trial in patients with inflammatory bowel disease involving the rectum, which is refractory to medical therapy. Total proctectomy might eventually find scant application in patients with inflammatory bowel disease.

Twenty-five hospitalized patients were studied prospectively with [67Ga]citrate (GA) abdominal scintillation scanning in an attempt to define its role in the evaluation of patients with active inflammatory bowel disease (IBD). There were nine patients with ulcerative colitis (UC), seven with Crohn's disease (CD), and nine controls. In four patients, two with UC and two with CD, a tissue/plasma radioactivity ratio was obtained and compared to normals. All the UC patients had positive GA scans and only one of seven of the CD patients had a positive scan. There were no false positive scans. Scans performed after a 3- or 5-day delay were more accurate than 6-hr scans alone. Well-delineated colinic radioactivity 6 hr after injection which persists for 3 to 5 days indicates the presence of UC in patients with IBD, while a negative scan is more consistent with active CD. Colonic uptake at 6 hr which clears by 48 or 72 hr is not indicative of UC. This procedure aided in following the course of UC, delineating the extent of disease, and in differentiating active CD from an intraabdominal abscess. Tissues from UC patients had increased tissue/plasma ratioactivity ratios while tissues from CD patients had normal or decreased ratios which were consistent with the imaging data.

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.

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.

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.
