Cryptal lymphocytic coloproctitis: a new phenotype of lymphocytic colitis?

BACKGROUND/AIMS: Lymphocytic colitis is a clinicopathological entity characterised by protracted watery diarrhoea and an increased number of intraepithelial lymphocytes (IELs) in the surface epithelium of the colonic mucosa. This report describes two patients with symptoms similar to those of lymphocytic colitis and an increased number of IELs, but within the cryptal epithelium. METHODS: The numbers of IELs were assessed in colorectal biopsies from the two patients. Sections were stained immunohistochemically for CD3, CD8, CD20, and TIA1. RESULTS: The colorectal biopsies had an abnormally high number of IELs in the epithelium of the crypts but not in the surface epithelium. The IELs in the crypts were CD3+++, CD8+, TIA1+, and CD20-. CONCLUSIONS: The histological diagnosis in these two patients was cryptal lymphocytic coloproctitis. Patients with similar symptoms and an increased number of IELs in the surface epithelium are now filed at this department as having surface lymphocytic coloproctitis. Immunohistochemistry showed that the cryptal IELs were cytotoxic suppressor T cells. Interestingly, a case of cryptal lymphocytic colitis was recently recorded in a non-human primate dying after years of protracted chronic diarrhoea. It is possible that antigens present in the lumen of the crypts elicit a lymphocytic reaction within the cryptal cells.

Fistulizing Crohn's disease.

Fistulas are common in Crohn's disease. A population-based study has shown a cumulative risk of 33% after 10 years and 50% after 20 years. Perianal fistulas were the most common (54%). Medical therapy is the main option for perianal fistula once abscesses, if present, have been drained, and should include antibiotics (both ciprofloxacin and metronidazole) and immunomodulators. Infliximab should be reserved for refractory patients. Surgery is often necessary for internal fistulas.

Colitis cystica profunda: self-inflicted by rectal trauma? Report of a case.

Colitis cystica profunda (CCP) is a rare benign condition with a controversial etiology. We report a case of CCP in a patient with a history of anal masturbation, supporting an acquired traumatic etiology. Diagnosis was assisted by transrectal ultrasound. The patient was successfully treated by local excision.

Colonic inflammation and nonsteroidal anti-inflammatory drug administration. An assessment of the frequency of the problem.

Over an 18-month period at a single clinic, 43 new cases of colonic inflammation have been diagnosed (19 proctitis only). Crohn's colitis has been excluded from this analysis. In all these subjects a careful drug history has been taken in a prospective manner and in 4 of these 43 patients colonic inflammation appeared to be directly related to non-steroidal anti-inflammatory drug (NSAID) administration (mefenamic acid, 2; piroxicam, 2). In all 4 patients there was a time interval (mean 3 months) between initiation of treatment with NSAID and presentation with diarrhoea and weight loss. Pathological findings were minor and biochemical changes insignificant, in contrast to the protracted troublesome symptoms. Resolution of symptoms was very rapid on discontinuation of NSAID medication but 2 patients experienced immediate return of symptoms following inadvertent rechallenge. Approximately 10% of newly diagnosed colitis may be related to NSAID administration. Subjects taking NSAID medications appear to be five times more likely to develop colonic inflammation than the general population.

Proctitis and proctosigmoiditis--a need to identify the extent of disease in epidemiological surveys.

Proctitis and proctosigmoiditis may be distinct clinical entities. The lesions are restricted to the rectum or extend proximally to involve the sigmoid colon, respectively. Barium enema examination should be normal proximal to the rectum and sigmoid colon. Histology is used merely to confirm the disease process. We provide evidence drawn from a large epidemiological database that significantly more patients with proctitis than proctosigmoiditis followed over a mean period of 11 years became asymptomatic or had their diagnosis revised to a non-inflammatory bowel disease condition (p < 0.05). The 2 groups were well-matched for age, sex, duration of disease and received similar medical treatment. Future epidemiological studies and therapeutic trials should make a distinction between proctitis and proctosigmoiditis.

Treatment tolerance and early complications with extended field irradiation in gynaecological cancer.

Treatment tolerance and early complications have been analysed in patients treated with extended field irradiation and pelvic irradiation alone. At the Centre Georges-François Leclerc, 126 patients were treated for carcinoma of the uterine cervix and endometrium from May, 1972 to November, 1974. All patients received external irradiation using a 25 MV X-ray beam. Follow-up has been nearly complete in all patients with the minimum follow-up being 15 months and the average 24 months. Treatment tolerance was approximately the same for all field sizes except when the field was extended to the top of D12. In this situation the patients occasionally required a short rest during their irradiation. The age of the patient was found to contribute significantly to the tolerance, with 70% of the patients who experienced poor tolerance being older than 60 years. Complications were evenly distributed in all all catagories of field size and appeared to be affected only by age and previous surgery. Of the patients who experienced complications 68% were older than 60 years, and of the 37 patients who had previous surgery, 32% had a complication. With certain treatment modifications the treatment tolerance and early complications appear acceptable when using extended field irradiation for gynaecological cancer.

[Quality of life in patients with inflammatory bowel diseases: translation to Portuguese language and validation of the "Inflammatory Bowel Disease Questionnaire" (IBDQ)].

BACKGROUND: Crohn's disease comprises, together with ulcerative colitis, the inflammatory bowel diseases, which because their morbidity and chronic evolution have a considerable impact on the patient's quality of life. The measurement of quality of life requires the determination of the degree of subjective well-being attributed to the lack of symptoms, to psychological state and daily activity, and is useful as an instrument of evaluation, both in clinical trials and health programs. Inflammatory Bowel Disease Questionnaire is an instrument developed by North-American investigators of McMaster University which reproducibility and validity has been determined in several countries studies, and has shown its use in the measurement of the quality of life of patients with inflammatory bowel diseases. AIMS: Our purpose was to translate that instrument into Portuguese language, its adaptation to Brazilian culture and verify its psychometric properties (validity and reproducibility). METHODS: It was applied to a population of 50 inflammatory bowel diseases patients (24 with Crohn's disease, 26 with ulcerative colitis). To test the criteria and construction validity of the instrument's, it was compared with SF-36, a general questionnaire for establishing quality of life, and the Crohn's Disease Activity Index and Lichtiger's Index. RESULTS: The correlations obtained were mostly moderate. About the intestinal diseases activity index, Lichtiger's index showed better correlations than Crohn's Disease Activity Index. To evaluate its reproducibility, the instrument was applied on three occasions, twice by the same observer (12 days average between applications) and once by a second observer, resulting in a high degree of intra- and interobserver correlation. CONCLUSIONS: Portuguese version of Inflammatory Bowel Disease Questionnaire is a valid and reproducible instrument which can be used to evaluate the quality of life of Brazilian inflammatory bowel diseases patients.

Short- and long-term outcomes of ileal pouch-anal anastomosis for ulcerative colitis.

UNLABELLED: Ileal pouch-anal anastomosis was an important advancement in the treatment of ulcerative colitis. The aim of this study was to determine whether early complications of ileal pouch-anal anastomosis in patients with ulcerative colitis are associated with poor late functional results. PATIENTS AND METHODS: Eighty patients were operated on from 1986 to 2000, 62 patients with ileostomy and 18 without. The early and late complications were recorded. Specific emphasis has been placed on the incidence of pouchitis with prolonged follow-up. RESULTS: The ileostomy was closed an average of 9.2 months after the first operation. Fourteen patients were excluded from the long-term evaluation; 6 patients were lost to regular follow-up, 4 died, and 4 patients still have the ileostomy. Of the 4 patients that died, 1 died from surgical complications. Early complications after operation (41) occurred in 34 patients (42.5%). Late complications (29) occurred in 25 patients as follows: 16 had pouchitis, 3 associated with stenosis and 1 with sexual dysfunction; 5 had stenosis; and there was 1 case each of incisional hernia, ileoanal fistula, hepatic cancer, and endometriosis. Pouchitis occurred in 6 patients (9.8%) 1 year after ileal pouch-anal anastomosis, 9 (14.8%) after 3 years, 13 (21.3%) after 5 years, and 16 (26.2%) after more than 6 years. The mean daily stool frequency was 12 before and 5.8 after operation. One pouch was removed because of fistulas that appeared 2 years later. CONCLUSIONS: Ileal pouch-anal anastomosis is associated with a considerable number of early complications. There was no correlation between pouchitis and severe disease, operation with or without ileostomy, or early postoperative complications. The incidence of pouchitis was directly proportional to duration of time of follow-up.

Sulphasalazine: a review of 40 years' experience.

Sulphasalazine, devised by Dr Nana Svartz for the treatment of 'infective polyarthritis', has been used in the treatment of inflammatory bowel disease for more than 40 years. Many controlled trials have shown that sulphasalazine 4g daily will induce remissions in between one-half and three-quarters of patients with acute attacks of ulcerative colitis. When given in a dosage of 2g daily it will prevent relapses in quiescent colitis. Relapses are 5 times more likely in untreated patients. It is less effective in Crohn's disease, where it exerts only a transient benefit in patients with active colonic disease and fails to prevent relapse or recurrence. Sulphasalazine is absorbed from the small intestine, re-excreted in bile and carried to the colon, where its azo bond is split by bacteria to release sulphapyridine, which is absorbed and is responsible for most of the drug's side effects, and 5-aminosalicylic acid, which is the active therapeutic moiety of the drug and exerts a beneficial topical action on the colonic mucosa. Side effects are common but are mainly reversible and not serious. Those related to high concentrations of sulphapyridine and to poor acetylation of the drug include gastrointestinal intolerance, malaise, headache, arthralgia, drug fever, effects on red blood cells and reversible male infertility. More serious, idiosyncratic side effects are skin rashes, leucopenia and agranulocytosis. Rarely, neurotoxicity, hepatotoxicity, polyarteritis, pulmonary fibrosis, a lupus-like syndrome and haemorrhagic colitis are produced. It is possible to desensitise most patients with drug-induced skin rashes. A number of less toxic alternatives to sulphasalazine have been devised and are undergoing trial. They either convey 5-aminosalicylic acid in a coated tablet to the colon or, when conjugated to a non-toxic carrier, release 5-aminosalicylic acid by bacterial cleavage there. Sulphasalazine remains a most useful drug in the treatment of inflammatory bowel disease after 40 years of use.

Radiology of invasive amebiasis of the colon.

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.

Mesalazine (5-aminosalicylic acid) suppositories in the treatment of ulcerative proctitis or distal proctosigmoiditis. A randomized controlled trial.

A multicentre double-blind study was conducted to evaluate the efficacy and tolerability of 1 g or 1.5 g mesalazine daily compared with placebo in 94 patients with mild to moderate distal proctosigmoiditis (less than 20 cm). The study end point was the determination of clinical, endoscopic, and histologic remission rates at 4 weeks. Eleven patients, nine receiving placebo and two receiving 1.5 g mesalazine, withdrew during trial, mostly because of worsening of symptoms. At 4 weeks clinical remission was achieved in 7 of 31 (39%) patients with placebo, in 22 of 32 (69%) patients in the 1 g mesalazine group, and 23 of 31 (74%) patients in the 1.5 g mesalazine group. No serious clinical or biochemical side effect of treatment was reported. Mesalazine suppositories are safe, well tolerated, and very effective in patients with active distal proctosigmoiditis: 500 mg twice daily appears a suitable dose regimen.

Intestinal intraluminal continuity is a prerequisite for the distal bowel motility response to feeding.

BACKGROUND: We wanted to elucidate further the regulation of the intestinal motility response to feeding. METHODS: After intraduodenal administration of an oleate solution, mimicking a meal, the distal bowel motility and the plasma levels of bile acids, cholecystokinin (CCK), and neurotensin were monitored in patients operated on with restorative proctocolectomy (n = 4) or low anterior resection of the rectum (n = 4). Investigations were performed both with and without a diverting loop ileostomy. RESULTS: Intraduodenal sodium oleate elicited a prompt and significant increase in distal bowel motility. The motility response failed to appear when the luminal flow was diverted by a loop ileostomy. An increase in plasma CCK preceded the motility increase, but CCK was increased also in patients with a loop ileostomy. Whereas plasma bile acid levels were significantly increased after 30-45 min (p < 0.05), both with and without a loop ileostomy, neurotensin levels were not affected. CONCLUSION: Intestinal continuity is a prerequisite for the distal bowel motility response, indicating that apart from other possible mechanisms, luminal factors are involved in the regulation of intestinal motility.

[Clinical aspects of inflammatory diseases of the large bowel with reference to coloscopy (author's transl)].

Ulcerative colitis and regional colitis Crohn are the most frequent inflammatory diseases of the large bowel in Europe. Clinical differentiation of these disorders are difficult. Diarrhoe with bloody stools are predominant. In cases with Morbus Crohn anorectal fistulas and involvement of the terminal ileum are frequently found. In cases with ulcerative colitis anorectal fistulas are more rare but in this disease a carcinoma of the colon often develops, especially when the course is severe and the involvement of the colon is extended. Clinical symptoms, courses and complications of both diseases are described. In differential diagnoses endoscopic procedures especially coloscopy play an important role. In cases of ulcerative colitis about 90% the rectum is involved. Spontaneous haemorrhage of the colonic mucosa with edema and pseudopolyps are typical endoscopic findings. Most cases with Crohn's disease show flat and irregular ulcers within a normal mucosa. In later stage a "cobble stone" relief is demonstrable. Endoscopy and guided biopsy are not only important for differential diagnosis but also for treatment and prognosis.
