Tumor-specific immunity to carcinoma of the colon, pancreas and stomach was assayed by tube LAI. Cancers of the colon, pancreas and stomach, were shown to possess organ-type specific neoantigens. In 115 patients with colon cancer, 100%, 75%, 61% with Dukes' A, B and C cancer were LAI positive, respectively. Even a microfocus of in situ cancer in a colon adenoma was sufficient to stimulate measurable tumor-specific immunity in the host. In Dukes' D cancer, 25% of patients with widespread metastasis were positive, whereas 100% with solitary lesions were positive. Reactive leukocytes from patients with colon cancer did not react to extracts of normal bowel mucosa or villous adenoma from LAI-negative patients. Leukocytes from 19% (3 of 16) of patients with colon adenomas reacted to the extract of colon cancer but not normal colon mucosa. Moreover, the LAI-positive response of the patients with colon adenomas or colon cancer is directed to a colon cancer TSA which is linked to beta2-microglobulin. These studies suggest that some colon adenomas express TSA before morphological evidence of cancer. It is not known if the acquisition of a cell surface TSA is an irreversible step toward unrestrained growth and metastasis. In pancreatic cancer, 100% of patients with cancers less than 5 cm and without metastasis were LAI positive, whereas 29% were positive when the cancer was greater than 5 cm or had metastasized. In Patients with stomach cancer, 100% with Stage II and 46% with Stage III and IV cancer were LAI-positive. Leukocytes from patients with other GIT cancers and from patients with inflammatory bowel disease or pancreatitis did not react with extracts of colon, stomach or pancreatic cancer. Leukocytes from patients with metastatic cancer, usually did not react in the tube LAI assay because their surfaces were coated in vivo with TSA. LAI reactivity was present when CEA was not detectable and when CEA levels were elevated LAI activity was often absent. The present study suggests that the automated tube LAI shows sufficient promise to warrant studies to determine its efficacy for the diagnosis of GIT cancers.

The incidence of antibodies to maize using an immunofluorescent technique has been found to be 14% in controls, 33% in Crohn's disease, 50% in ulcerative colitis and 44% in coeliac disease. This result indicates that humoral immunity to maize is probably unimportant in the pathogenesis of Crohn's disease. The similar incidence of antibodies in the inflammatory bowel disease and coeliac groups suggests absorption of dietary antigen secondary to an increased mucosal permeability.

Among the rheumatic diseases, non so clearly illustrates the relations between host and environmental factors as the seronegative spondyloarthropathy group of disorders. The strongest association is with the histocompatibility antigen HLA-B27, which accounts for a striking susceptibility to these diseases and is present in over 90% of individuals with idiopathic ankylosing spondylitis. Next in importance appears to be a difference in sex penetrance with males predominating in all categories. The most dramatic sex relationship is with postvenereal Reiter's syndrome which has a male-to-female ratio of nearly 50:1. Another potent host factor is age, with increased predisposition to onset at puberty and young adulthood in HLA-B27-positive patients. Environmental or possibly infectious agent influence are most apparent in Reiter's syndrome, where the antecedent circumstances of venereal contact and bacillary dysentery are frequent precipitating events. Secondary forms of peripheral arthritis, radiographic sacroiliitis, and ankylosing spondylitis frequently occur in psoriasis and inflammatory bowel disease; in the case of peripheral arthritis, there is no or a significantly reduced association with HLA-B27 compared to AS or RS. Secondary factor seem to be contributing to spondyloarthropathy in these disorders. These iterrelations emphasize the powerful effects of host characteristics on the type of rheumatic disease syndrome acquired and provide superb opportunities for more precise understanding of disease pathogenesis and ultimate control through the integration of epidemiologic, clinical, and laboratory research.

To investigate the possible association of bacteremia with barium enema examinations, blood samples were obtained from 42 patients before and at 5, 10, and 20 min after administration of the enema. Patients with fever or symptoms suggestive of inflammatory bowel disease were not included in the study; neither were patients who had received antimicrobiotic medication during the preceding 3 months. Pour-plate blood cultures showed no bacteremia due to enteric organism in the 42 patients-a result at variance with previously published reports.

Convulsions have complicated the surgical management of life-threatening inflammatory bowel disease in five patients. These patients experienced a transient, generalized convulsive disorder and toxic ambylopia. Results of neurological examination were unremarkable. Treatment included metabolic stabilization along with the administration of oxygen and anticonvulsive medication. Various factors, such as hypoxia, fluid overload, cerebral edema, steroid administration, and deficits in calcium, magnesium, and potassium, may have contributed to the cause of this complication.

Two patients with colonic adenocarcinoma and Streptococcus bovis endocarditis suggested a possible association between the two. Non-enterococcal Group D streptococci were isolated from fecal cultures of 11 of 105 controls, 35 of 63 patients with carcinoma of the colon, seven of 25 with inflammatory bowel disease, four of 21 with non-colonic neoplasms and five of 37 with other gastrointestinal disorders. All such streptococci examined for lactose fermentation were S. bovis. The prevalence of S. bovis in fecal cultures from patients with carcinoma of the colon was significantly increased (P less than 0.001) as compared to that in controls, and also to all other groups (P less than 0.001). No other group had results significantly different from those of controls (P less than 0.05) although patients with inflammatory bowel disease were more frequently carriers. The carrier state was unrelated to age, hospitalization status, colonic stasis, gastrointestinal bleeding or recent barium-enema examination. The implications of this association are unknown.

Nutritional depletion is a common feature of inflammatory bowel disease. The advent of total parenteral nutrition (TPN) has allowed nutritional repletion or maintenance while total bowel rest is achieved. The experience with total parenteral nutrition in inflammatory bowel disease is varied; our recommendations for use of total parenteral nutrition in specific situations are presented with a description of the techniques for administration in patients with inflammatory bowel disease.

Entamoeba histolytica is a protozoan that is endemic in various parts of the world, including some areas of the United States. It may live in the large bowel in its cyst form without harming the host (commensalism) or, for as yet poorly understood reasons, invade the tissues as a trophozoite producing invasive amebiasis of the colon. In a review of over 3,000 cases of invasive amebiasis, the clinico-pathologic forms of the disease were: ulcerative rectocolitis (95%), typhloappendicitis (3%), ameboma (1.5%), and fulminating colitis and toxic megacolon (0.5%). Different radiographic patterns are seen in each clinical form with varying degrees of specificity. It is vitally important that this disease be included in the differential diagnosis of large bowel pathology even in nonendemic areas. Several referral patients who have received inappropriate therapy for inflammatory bowel disease with near disastrous results are seen at one of our institutions (Loyola) each year.

The gastrointestinal tract is replete with immunocompetent tissue represented by appendix, Peyer's patches and nonaggregated lymphocytes in the intestinal epithelium. This local immune system plays a vital role in the physiologic immune response and in the control of food, drug, microbial or viral antigens. Under certain situations this lymphoid tissue may contribute to the immunological reactions underlying the pathogenesis of various diseases. Generalised deficiencies of the immune apparatus frequently give rise to disturbances of gastrointestinal function. Furthermore plenty of immune reactions occurring in connection with human inflammatory bowel disease have been described. Some immunologic features are reported as typical for a disease, the majority seems to indicate only nonspecific autoimmune reactions. The relevance of immunological mechanisms for the pathogenesis of these diseases is still not full evaluated.

A family with 4 of 10 first-degree relatives affected with inflammatory bowel disease (IBD) was studied to determine whether any distinct immunological abnormalities occur in the affected members, as compared with unaffected members of the family, normal controls, and other unrelated patients with IBD. Red cell blood type and HL-A phenotypes did not distinguish between healthy and affected members, although HL-A2, 32, B27, and B12 were the predominant haplotypes in members with IBD. There was no significant difference between the two groups in the lymphocyte subpopulation counts of T cells, B cells, and cells carrying Fc or complement receptors. The in vitro mitogen response, however, to phytohemagglutinin and pokeweed mitogen were depressed in the affected members. Serum IgA and C3 levels were significantly elevated in members with IBD compared to healthy subjects with values of 232 +/- 69 (mean +/- SD) versus 148 +/- 29 mg per dl for IgA (P less than 0.05) and 173 +/- 32 versus 115 +/- 22 mg per dl for C3 (P less than 0.025), respectively. Plasma and, to a lesser extent, peripheral lymphocytes from 2 affected members who were tested were cytotoxic to allogeneic colonic epithelial cells. Salivary IgA was normal in the affected family members and unrelated patients with IBD. However, the free secretory component of salivary IgA was absent or markedly depressed in family members, as well as in unrelated patients with ulcerative colitis. This deficiency of the secretory immune system appears to characterize more frequently ulcerative colitis than Crohn's disease and may compromise mucosal host defenses in IBD.
