Psychosomatics and psychoanalytic theory: The psychology of ulcerative colitis and Crohn's disease.

Psychoanalytic psychosomatic theory is reviewed here with particular reference to inflammatory bowel disease, that is, ulcerative colitis and Crohn's disease. The importance of recognizing empirical research findings in conjunction with clinical inference is stressed, as well as the usefulness of exploring the full relationship context of illness.

The extra-intestinal complications of Crohn's disease and ulcerative colitis: a study of 700 patients

The records of a series of 700 patients with inflammatory bowel disease, 498 with Crohn's disease and 202 with ulcerative colitis, have been analyzed to determine the relative incidence and characteristic features of their extra-intestinal manifestations. The group with Crohn's disease included 62 with colitis, 223 with ileocolitis, and 213 with regional enteritis. A consideration of the clinical patterns and an understanding of their pathophysiology suggested a subdivision into two main groups: one "colitis related" and one related to the pathophysiology of the small nonspecific third group. Group A, colitis related, comprises joint, skin, mouth, and eye disease. The complications might be immunologically determined, were closely associated with active inflammation, and often responded to medical or surgical treatment of the underlying bowel disease. They occurred in 36% of the entire series of patients: joints were involved in 23%, skin in 15%, and mouth and eye each in 4%. Pyoderma gangrenosum was observed most often in ulcerative colitis and erythema nodosum most often in granulomatous colitis. The incidence of Group A complications was higher in disease involving the colon (42%) than in disease restricted exclusively to the small bowel (23%). There were interrelationships among the various members of Group A, with multiple manifestations occurring in a third of affected patients. Group B, related to small bowel pathophysiology, includes malabsorption, gallstones, kidney stones, and non-calculous hydronephrosis and hydroureter. Disorders in this group were generally related to the severity of the disease in the small bowel and tended to persist even in the absence of active inflammation. In contrast to Group A, this group occurred most frequently in small bowel disease, and least in colonic disease. Malabsorption was virtually confined to the patients with small bowel disease (10% incidence), while gallstones and renal stones were also both more frequent in Crohn's disease (11% and 9% respectively), the latter usually in association with small bowel resection or ileostomy. Group C, found in a small percentage of patients, consists of nonspecific complications, including osteoporosis (3%), liver disease (5%), peptic ulcer (10%), and amyloidosis (1%).     

Appendectomy and the risk of developing ulcerative colitis or Crohn''s disease: results of a large case-control study. South Limburg Inflammatory Bowel Disease Study Group

Copper amine oxidase from lentil seedlings was shown to be able to catalyze the oxidative deamination of the indoleamines tryptamine, 5-hydroxytryptamine, and 5-methoxytryptamine. These compounds showed saturation kinetics with Km values as normal substrates, but their oxidation led to irreversible loss of enzyme activity suggesting a covalent interaction with the enzyme, most probably through its cofactor 6-hydroxydopa (2,4,5-trihydroxyphenylalanine). These indoleamines acted as irreversible inhibitors of the enzyme only in the absence of oxygen but they brought about changes in the electronic spectra of the enzyme both in aerobiosis and in anaerobiosis. This study reports on the mechanism by which these compounds inhibit lentil amine oxidase which involves first the oxidation of indoleamines bound to 6-hydroxydopa followed by the formation of an irreversible covalent derivative. The same inhibitory mechanism could possibly lead to inactivation of mammalian amine oxidases involved in serotonin neurotransmitter metabolism in conditions of ischemia or hypoxia.     

Localized tumor-like lesions in ulcerative colitis and Crohn's disease of the colon

Ulcerative colitis and Crohn's disease of the colon may manifest roentgenographically as localized tumor-like lesions of the colon. Such lesions are often of inflammatory origin but are likely to be mistaken for polypoid carcinoma or infiltrating submucosal malignancy. Four patients with localized inflammatory lesions of the colon that mimicked a neoplastic process are reported. The clinical features and the radiological-pathological correlation of such lesions are presented.     

Use of parenteral feeding in the multimodality treatment of Crohn's disease and nonspecific ulcerative colitis

The paper reviews publication on the use of complete parenteral feeding in the multimodality treatment of inflammatory bowel disease. Complete parenteral feeding was performed in patients with skeletization and physical retardation, in severe diseases, in inefficiency or intolerance of conventional therapy with sulfanilamides and steroids, in those who had intestinal fistulas, as well in the preparation of patients for surgical treatment. The use of complete parenteral feeding, under the above circumstances allow one to achieve persistent remission, spontaneous healing of intestinal fistulas, elimination of abnormal metabolism, nutrition, constitution, water-electrolyte balance, to reduce a surgical risk and the incidence of postoperative complications and the length of patients' hospital stay.     

The role of coloscopy in the differential diagnosis between idiopathic ulcerative colitis and Crohn's disease of the colon

The authors point out the striking significance of coloscopy in establishing a correct diagnosis of inflammatory diseases of the colon. In particular, the most valuable endoscopic features are indicated which may permit distinguishing between idiopathic ulcerative colitis and Crohn's disease of the colon. Differentiation between these two diseases cannot always be achieved by means of available diagnostic procedures other than coloscopy. Moreover, the endoscopic findings enable an assessment to be made of the extent, stage, severity and course of either disease. The authors' experience encompass 2,478 coloscopy examinations: the observed cases of idiopathic ulcerative colitis are 182, those of Crohn's disease of the colon are 104.     

Elevation of phospholipase A2 protein in sera of patients with Crohn's disease and ulcerative colitis

The protein mass of group II phospholipase A2 (PLA2) levels were immunochemically measured in sera of 43 patients with Crohn's disease (CD), 43 patients with ulcerative colitis (UC), and 35 healthy volunteers, and compared with PLA2 enzymatic activity. Serum immunoreactive group II PLA2 (IR-PLA2 II) levels of active CD patients were significantly higher than those of the controls and inactive CD patients. Serum IR-PLA2 II levels were also significantly greater in patients with severe UC and moderate UC than in the controls and patients with mild UC. Serum IR-PLA2 II levels were found to be closely correlated with serum PLA2 activity in patients with CD and UC. Serum IR-PLA2 II levels and PLA2 activity decreased by antiinflammatory treatment in six patients with CD and two with UC. These results suggest that serum IR-PLA2 II levels can be a useful parameter in the evaluation of disease activity of CD and UC, and that elevated PLA2 enzymatic activity in sera of patients with CD and UC is attributable to increased protein concentration of group II PLA2, in agreement with our previous results.     

Intestinal expression of human heat shock protein 90 in patients with Crohn's disease and ulcerative colitis

Heat shock proteins are induced by several stress factors and are potential antigens in autoimmune disorders. Expression of heat shock protein 90 (HSP 90) was investigated in patients with inflammatory bowel disease and normal controls. We combined western blot analysis with laser densitometry for quantitation. Localization of HSP 90 was investigated by immunohistochemistry. Western blots showed a significant mucosal expression of HSP 90, which was comparable in patients and controls. There was also no difference between normal and inflamed mucosa in inflammatory bowel disease. In immunohistochemical staining studies, HSP 90 was detected in epithelial cells, mononuclear cells, giant cells, nerve cells, and endothelial cells of small vessels. There was no difference in the intensity of staining or localization in patients with inflammatory bowel disease compared to controls. These findings render a potential protective or immunogenic function of HSP 90 in inflammatory bowel disease unlikely.     

Crohn's disease and ulcerative colitis mucosal T cells are stimulated by intestinal epithelial cells: implications for immunosuppressive therapy

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory diseases, and their pathogenesis is attributed, in part, to alterations of the mucosal immune system. This study was designed to define the possible contribution of epithelial cells to the activation of lamina propria T lymphocytes (LPTs) in CD and UC. METHODS: LPTs isolated from CD, UC, and control surgical specimens were cocultured with freshly isolated allogeneic or autologous epithelial cells or epithelial cell lines. Resulting T-cell proliferation was evaluated by tritiated thymidine incorporation on day 5. RESULTS: When intestinal epithelial cells were used to stimulate mucosal T-cell proliferation, CD and UC LPTs were less responsive than control LPTs (p < 0.05 and p < 0.03, respectively). This difference between inflamed and control T cells was consistently observed by using a variety of different intestinal epithelial cell types. CONCLUSIONS: CD and UC mucosal T cells are hyporesponsive to activation by intestinal epithelial cells when compared with control LPTs. Elucidating the mechanism underlying the differential activation of CD and UC LPTs may help to better understand the immunopathogenesis of these conditions.     

Consensus inflammatory intestinal diseases in children: ulcerative colitis and Crohn disease. Work Group Academic Medical Center, Amsterdam

Members of different societies, including Paediatrics, Gastroenterology, Clinical Chemistry, Radiology and Pathology, involved in the treatment of children with inflammatory bowel disease (IBD) reached consensus during 12 meetings about definition, clinical and diagnostic work-up as well as initial treatment options in paediatric IBD. On the basis of history and physical examination a distinction is made between colitis-like or Crohn-like appearance. Further laboratory investigations are required in the presence of malnutrition, extraintestinal manifestations or growth retardation. Pathology plays an important part in the final diagnosis. Special attention is given to pubertal staging and height measurements as routine aspects of the treatment of children with IBD.     

Use of technetium-tagged white blood cells in patients with Crohn's disease and ulcerative colitis: is differential diagnosis possible?

BACKGROUND: Studies have suggested that scans with technetium-tagged white blood cells (WBC-Tc99m) may be equal to endoscopy in the assessment of extent and activity of inflammatory bowel disease (IBD). OBJECTIVE: We have retrospectively examined the accuracy of WBC-Tc99m scans in differentiating continuous from discontinuous colitis in pediatric IBD. MATERIALS AND METHODS: There were 207 children in the study (96 boys, 111 girls, median age 13 years). This included 29 controls - children with no gastrointestinal disease (NL) who underwent WBC-Tc99m scans for other medical problems. Scans were obtained at 30 minutes and 2-4 hours following injection. Scans were interpreted as showing continuous colitis, discontinuous colitis, or no colitis. RESULTS: In the 77 children with active Crohn's disease (CD) of the colon, the scans revealed discontinuous uptake in 63 children and continuous uptake in 14. In the 29 children with ulcerative colitis (UC), 23 scans showed continuous uptake and 6 revealed discontinuous uptake. Two of these 6 showed focal activity near the appendix, and subclinical appendicitis could not be excluded. Another child was bleeding and the scan could have been misinterpreted as showing small- bowel inflammation. In the last three patients, skip areas were clearly identifiable. In none of these last three patients were the biopsies typical of CD (i. e., no granuloma was identified) nor was inflammation patchy. In summary, of the 106 scans showing inflammation, 6 were classified into the wrong group. CONCLUSION: These data show that WBC-Tc99m scanning can be useful in distinguishing discontinuous from continuous colitis.     

The dilemma of Crohn's disease: ileosigmoidal fistula complicating Crohn's disease

Between 1965 and 1975, 27 patients underwent surgical treatment for ileosigmoidal fistulas complicating Crohn's disease at the Cleveland Clinic. There was no death and no anastomotic leak. The preferred procedure is resection of the ileocecal area involved by Crohn's disease with ileocolic anastomosis and a separate segmental resection of the sigmoid colon with colocolic anastomosis. A covering temporary loop ileostomy is used when there is associated pelvic sepsis or small-bowel obstruction.     

Liver disease in ulcerative colitis: an epidemiological and follow up study in the county of Stockholm

In an epidemiological study of the incidence of ulcerative colitis (UC) in the county of Stockholm between 1955 and 1979, 1274 patients with UC were discovered. Almost all these patients had regularly been investigated with liver function tests; 142 (11%) of them showed signs of hepatobiliary disease. A follow up study on all 142 patients with abnormal liver function and UC was made between 1989 and 1991 to evaluate the cause of the liver abnormality and to find out if the liver disease had affected the survival rates. At follow up, eight patients were reclassified as having Crohn's disease, 60 had developed normal liver function as judged from test results, while the remaining 74 still had signs of hepatobiliary disease. The most common explanation for a transient abnormality in liver function was active colitis. The temporary signs of liver injury were not associated with changes in survival rates for these patients. Infections, especially those because of hepatitis B and C virus transmitted by blood transfusions accounted for the abnormalities in liver function in 21 patients, nine of which had a chronic, but non-fatal course. Twenty nine (2.3%) of the patients developed primary sclerosing cholangitis (PSC), and 12 of them died during the study period four because of cholangiocarcinoma and eight because of hepatic failure; one patient had a transplant. The estimated median time of survival from the first presentation of evidence of a liver function, compatible with the diagnosis of PSC, to death or liver transplantation was 21 years. A comparison of survival rates in patients with UC and patients with UC and concurrent PSC showed, a significant reduction in survival in the PSC group (p<0.0001). The number of patients with UC who developed PSC remained constant during the study period. Thus, although evidence of abnormal liver function is a common finding in UC, a spontaneous return to normal levels is common. In this study, which did not have a selection bias, the median time of survival among PSC patients was far longer than previously described although development of PSC among patients with UC does significantly reduce the estimated median time of survival.     

Tuberculous colitis mimicking Crohn's disease: utility of computed tomography in the differentiation

The case of a 50-year-old woman with pathologically proven tuberculous colitis is reported. Clinical course, single-contrast barium enema, and colonoscopy suggested Crohn's disease. Computed tomography allowed the correct diagnosis of tuberculous colitis as it showed asymmetric thickening of the colonic wall and enlarged necrotic lymph nodes. This case suggests that the diagnosis of tuberculous colitis may be difficult and raises the differential diagnosis with Crohn's disease. Our observation suggests that computed tomography can be helpful for the diagnosis and may avoid unnecessary exploratory laparotomy.     

Ileoanal anastomosis for ulcerative colitis: results of an evolutionary surgical procedure

BACKGROUND/AIMS: Proctocolectomy with ileoanal anastomosis (IAA) has proved to be the most suitable surgical treatment for ulcerative colitis. The aim of this study was to compare the results of IAA according to the evolution of surgical procedures and particularly to compare the results of stapled versus hand-sewn anastomosis. METHODOLOGY: From 1984 to 1996, 37 men and 31 women were operated on in our centre for ulcerative colitis. The anastomosis between the J pouch and the dentate line was handsewn in 35 patients (group 1) and stapled in 33 patients (group 2). RESULTS: The mean operative time was significantly shorter in group 2 as compared with group 1 (265+/-59 vs. 323+/-53, p<0.01, respectively), whereas morbidity and functional results were comparable in both groups. In 10 patients with stapled IAA, a diverting ileostomy was not performed and the morbidity in this group did not increase. CONCLUSIONS: These results suggest that stapled IAA anastomosis is a safe procedure. The stapling technique of IAA simplifies total excision of the rectum and could mean that a diverting ileostomy is not necessary.
