Sera from patients with ulcerative colitis or Crohn's disease had elevated titers to colon antigen from germ-free rats significantly more often than sera from patients with gastroenteritis, irritable colon, non-gastrointestinal diseases, and healthy controls. Elevated anticolon titers in significant frequency were also found in patients with liver cirrhosis, urinary tract infections, and in polyposis coli and their relatives. Females with ulcerative colitis had, on an average, higher titers than men especially in the age group 30 years and over. In Crohn's disease the antibody titers often increased with time--as opposed to those in ulcerative colitis and non-gastrointestinal diseases. In conjunction with results published earlier, the present work supports the assumption that the antibodies in ulcerative colitis patients react with antigenic determinants distinct from those recognized by the colon antibodies present in other groups, including patients with Crohn's disease and polyposis.

Prolyl hydroxylase activity in rectal mucosa was found to be significantly greater in 11 patients with Crohn's disease than in 11 control subjects with the irritable bowel syndrome and 16 patients with ulcerative colitis (P less than 0.005). Seven of the patients with Crohn's disease had a histologically normal rectum. This abnormality in apparently normal mucosa supports the concept that Crohn's disease is a 'continuous' disease of the gastrointestinal tract. Although there was no significant difference in prolyl hydroxylase activity between control subjects and patients with ulcerative colitis, those patients with quiescent disease tended to have lower values than those with active mucosal inflammation. Prolyl hydroxylase activity could not, however, be detected in the sera of either healthy control subjects or patients with inflammatory bowel disease.

Five hundred and twenty-two African and Indian patients were studied, including 206 with duodenal ulcers, 25 with irritable colon, 51 with oesophagitis, 31 with pancreatitis, 14 with ulcerative colitis or Crohn's disease, 71 miscellaneous gastrointestinal diagnoses and 124 controls. The mean ages were similar in each group. Every patient underwent endoscopy and a detailed psychosocial questionnaire was applied. Comparison of occupations of patients and their patients was investigated on 3 scales, for Status/Prestige (9 levels), Responsibility (5 levels) and Control over Others (10 levels). Significantly more patients with duodenal ulcers were in the lowest group in terms of occupational authority compared to other diagnoses and controls. Similar number of all groups had been urban for their entire life. Stress was present in the 10 days preceding an attack in significantly more Indian males with duodenal ulcers compared to controls. Upward shifts in prestige had not occurred in African male patients with duodenal ulcers when compared to their parents but had occurred among Indian men. More duodenal ulcer patients were in the very lowest occupational authority category compared to other groups. It may thus not be occupational prestige as such that is important, but factors associated with it, such as lack of control over others and, among Indian men, stresses associated with social disruption following upon occupation mobility.

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 patient over 40 years of age who complains of lower abdominal pain, constipation or diarrhea or both, and increased flatulence should be suspected of having diverticulosis. When pain becomes more severe and persistent, diverticulitis must be considered. Diagnosis depends on roentgen demonstration of the presence of diverticula. Sigmoidoscopy and barium enema study are essential to exclude coexisting disease but in diverticulitis may need to be postponed until severe local and systemic signs of inflammation have subsided. A number of diseases can simulate diverticulitis, and differential diagnosis may present considerable difficulty. Irritable colon syndrome and acute appendicitis may be indistinguishable clinically from diverticulitis. Differentiation from carcinoma is usually not difficult, but exclusion of coexistent carcinoma may be impossible except by resection. Ulcerative colitis is also easily distinguished except when, rarely, it coexists. Crohn's disease of the colon is less easily differentiated, especially in patients over 40, in whom the two diseases often coexist. Other colonic diseases, such as ischemic colitis, and pelvic inflammatory diseases usually show characteristic features which make them readily distinguishable from diverticulitis.

This paper reviews our five years' clinical experience (1987 to 1991) of 22 patients with inflammatory bowel disease (IBD). There were 12 patients with Crohn's disease and 10 patients with ulcerative colitis. The mean age at diagnosis was 8.7 years (2 to 14 years). Clinical impressions before referral were chronic diarrhea in 11, irritable bowel syndrome in 5, colon polyp in 4, lymphoma in 3, intestinal tuberculosis in 2, amoebic colitis in 2, ulcerative colitis in 2 children and other diseases. The mean interval from the onset of symptoms to the diagnosis of IBD was 18 months. Diagnosis of Crohn's disease was delayed for more than 13 months in 8 (67%), whereas that of ulcerative colitis was delayed for more than 13 months in 4 (40%). Diarrhea (50%), abdominal pain (36%) and rectal bleeding (36%) were the three most frequent presenting complaints of IBD. Moderately severe abdominal pain was a more common chief complaint in Crohn's disease (58%) than in ulcerative colitis (10%). Hematochezia (90% vs 17%) and moderately severe diarrhea (90% vs 75%) were more common gastrointestinal manifestations in ulcerative colitis than in Crohn's disease. The associated extraintestinal manifestations were oral ulcer in 7, arthralgia in 11 and arthritis in 4, skin lesions in 2, eye lesions in 2 and growth failure in 9 patients. Of 12 children with Crohn's disease, granuloma was found in 5, aphthous ulcerations in 8, cobble stone appearance in 8, skip area or asymmetric lesions in 6, transmural involvement in 7, and perianal fistula in 3. Among 10 children with ulcerative Colitis, there were crypt abscess in 8, granularity or friability in 10 and rectosigmoid ulcerations with purulent exudate in 8 children. The main sites of involvement in children with Crohn's disease were both the small and large bowels in 7 (58%), small bowel only in 2 (16%), and colon only in 3 (25%). Terminal ileum involvement was seen in 75% of Crohn's disease cases. The main sites of involvement in children with ulcerative colitis were total colon in 4 (40%), up to the splenic flexure in 2 (20%), rectosigmoid in 3 (30%) and rectum only in one (10%). Medical treatment including sulfasalazine, and systemic or topical steroid was administered initially in most patients. Seven of 12 patients with Crohn's disease and 2 of 10 patients with ulcerative colitis were operated on.(ABSTRACT TRUNCATED AT 400 WORDS)

The role of mycobacterial heat shock proteins (Hsp) of the 65 kilodalton Hsp family as a possible factor governing cell-mediated immune responses, leading to chronic mucosal inflammation, was examined. Purified peripheral blood mononuclear cells (PBMC) from patients with CD and ulcerative colitis (UC), and from healthy and disease controls were stimulated in culture with a highly purified, recombinant 65 kilodalton Hsp (rHsp65) of M. bovis BCG for 5 d. Cultures were then pulsed with 3H-thymidine for 24 h and uptake determined by liquid scintillation. We found that PBMC from patients with active CD exhibited a significant proliferative response to the soluble rHsp65 as compared with normal controls. In contrast, the proliferative responses of PBMC from patients with inactive CD, inactive and active UC, pancreatitis and cecal carcinoma were found to be not different from controls. Purified T cells or non-T cells of PBMC in the absence of antigen-presenting cells from active CD patients exhibited a lack of proliferative responses to the rHsp65 stimulation in culture. The data indicate an aberrant sensitization of T cells to the 65 kilodalton mycobacterial Hsp in a specific type of IBD, and thus may provide an important clue for the etiopathogenesis of Crohn's disease.

Significantly decreased levels of serumcholinesterase (CHE) were found in acute Crohn's disease (= CD) (3.2 +/- 1.0 KU/L) and acute ulcerative colitis (= UC) (3.54 +/- 1.6 KU/L) as compared to patients with mild or quiescient disease (CD: 5.5 +/- 1.1 KU/L; UC: 5.59 +/- 0.94 KU/L) and healthy controls (5.69 +/- 1.3 KU/L). Suppression of CHE was most evident in Crohn's colitis (2.98 +/- 1.0 KU/L) and extensive UC (2.96 +/- 1.28 KU/L). Intraindividual comparison showed an increase of CHE-levels during treatment with steroids and salicylates. There was no significant correlation to the reduced bodyweight-levels in severe IBD. Best correlations were seen between CHE/albumin (CD: r = +0.61; UC: r = +0.73) and CHE/hematocrit (CD: r = +0.50; UC: r = +0.61) in severe inflammatory bowel disease. The results of a discriminant analysis showed that CHE-levels can predict the degree of activity correctly in the majority of patients with CD and UC. It is suggested that the decrease of serumcholinesterase reflects an inhibition of liver synthesis as an acute phase response-induced by endotoxins and cytokines.

The history and etiology of inflammatory bowel disease which is characterized by two major disease processes: ulcerative colitis and Crohn's disease, remain unknown. Research is focussing on seven major areas of genetic, environmental and physiologic factors that apparently relate to this disease. Based on this background, a population based Inflammatory Bowel Disease Registry was established in 1987 in the Lehigh Valley area of southeastern Pennsylvania. Consent forms, patient data forms and protocols for operation and implementation were developed, and databases were designed to accommodate demographic, basic history, follow-up and relative history data. The databases were correlated with an IBD registry ID number which both enabled relational analyses and ensured confidentiality of data information. The registry continues to grow, providing feedback for both continued medical research and supportive information for IBD patients and their physicians.

Oxygen-derived free radicals and other reactive oxygen metabolites have emerged as a common pathway of tissue injury in a wide variety of otherwise disparate disease processes. This has given rise to the hope that efforts directed towards the pharmacologic control of free radical-mediated tissue injury (Reilly, P.M., Schiller, H. J. and Bulkley, G. B. (1991) Pharmacologic approach to tissue injury mediated by free radicals and other reactive oxygen metabolites. Am. J. Surg. 161: 488-503) may have particular application to patients suffering from Crohn's disease and/or ulcerative colitis. However, because tissue injury by any mechanism, even direct mechanical trauma, can elicit an inflammatory response which entails the secondary generation of toxic oxidants by neutrophils and tissue macrophages, it is important that the evidence for this association be examined critically, so as to discriminate the possibility of an etiologic role for these toxic compounds from their presence as a reflection of injury caused primarily by other agents. Similarly, in considering the therapeutic potential of free radical ablation for the treatment of patients with IBD it is important to distinguish between interventions that might specifically block the fundamental injury mechanism from those which would act in a more nonspecific, anti-inflammatory role.
