To detect and measure occult gastrointestinal bleeding, we have measured haemoglobin concentrations (by HemoQuant) in the clear fluid obtained after whole-gut lavage. In subjects with healthy gastrointestinal tracts, lavage-fluid haemoglobin concentrations were 0.5-5.1 mg/L, equivalent to daily blood loss of 0.1-1.1 mL. High concentrations were found for patients with colorectal cancer, severe diverticular disease, and rectal varices, in seven of sixteen patients with active inflammatory bowel disease, and in four patients with iron-deficiency anaemia thought to be due to gastrointestinal bleeding. In these four patients, estimated blood loss ranged from 2.6-24.5 mL per day. This method could have various research and clinical applications.

The prevalence, predictors, and significance of pneumatosis were determined in 50 patients with Crohn's disease who had abdominal CT scans to rule out abscess. The presence or absence of six CT descriptors and 17 clinical descriptors was documented. CT scans of a control group of 50 subjects without inflammatory bowel disease were also examined. Data was analyzed by two-sample t tests and Fisher's exact test. Pneumatosis was found in six of 50 patients with Crohn's disease and in none of the controls. Corticosteroid treatment was the single clinical variable relating significantly (P = 0.025) to pneumatosis, although trends toward absence of resection, short duration of illness, and more severe anemia were also evident in this group. This study suggests that the presence of pneumatosis alone does not dictate a specific course of treatment, but when pneumatosis is present, careful monitoring is required and therapy is based on the overall clinical picture.

To investigate whether the clinical history and basic laboratory test results can differentiate between an organic or functional cause of chronic diarrhea and thus avoid unnecessary hospital admissions and invasive procedures, we reviewed the charts of 58 adult patients admitted during 6 years because of chronic diarrhea who had normal stool and colonic examinations. The final diagnoses were irritable bowel syndrome in 34 patients, organic diarrhea in 21, and unknown cause in three. The following clinical data did not help in the differential diagnosis: age, sex, duration of diarrhea, presence of continuous diarrhea, abdominal pain, stool frequency or volume, and presence of stool mucus. Significant weight loss, nocturnal diarrhea, and the absence of tenesmus were associated with an organic cause. One or more laboratory alterations (increased erythrocyte sedimentation rate, anemia, hypokalemia, and low serum albumin level) were found in 62% of patients with organic diarrhea but in only 3% of those with functional disease; p less than 0.001. In 20 of 21 patients with organic diarrhea, an syndromic diagnosis (fat malabsorption, n = 13; inflammatory bowel disease, n = 4; and secretory diarrhea, n = 3) could be obtained with three simple tests (stool fat, rectal biopsy, and fecal water osmolality and electrolyte determination, respectively). Our study confirms that a detailed history and a few simple laboratory data can help to distinguish between functional and organic diarrhea and so avoid extensive investigation. The syndromic diagnosis of organic diarrhea can also be approximated with relatively easy tests.

The plasma kallikrein-kinin system is activated in Gram-negative sepsis and typhoid fever, two diseases in which bacterial products have been shown to initiate inflammation. Because a single intraperitoneal injection of bacterial cell wall peptidoglycan-polysaccharide polymers from group A steptococci (PG-APS) into a Lewis rat produces a syndrome of relapsing polyarthritis and anemia, we investigated changes in the role of the kallikrein-kinin system in this model of inflammation. Coagulation studies after injection of PG-APS revealed an immediate and persistent decrease in prekallikrein levels. High-molecular-weight kininogen levels decreased significantly during the acute phase and correlated with the severity of arthritis. Factor XI levels were decreased only during the acute phase. Antithrombin III levels remained unchanged, indicating that neither decreased hepatic synthesis nor disseminated intravascular coagulation caused the decreased plasma contact factors. Plasma T-kininogen (an acute phase protein) was significantly elevated during the chronic phase. PG-APS failed to activate the contact system in vitro. Thus the kallikrein-kinin system plays an important role in this experimental model of inflammation, suggesting that activation of this system may play a role in the pathogenesis of inflammatory bowel disease and rheumatoid arthritis in which bacterial products might be etiologically important.

We carried out an epidemiological study of ulcerative colitis in 279 Israeli kibbutzim (121,403 population). The prevalence on December 31, 1987 was 121.08 per 100,000 population. When the data were stratified according to ethnic groups, the highest point prevalence was found in Israeli-born Jews (220.56 per 100,000 population), more than in Asian-African-born, or European-American-born kibbutz members (139.20 and 78.73 cases per 100,000 population, respectively). There were 68 men and 78 women (ratio of 0.87). The average age of the patients in the year of this survey was 46 years; it was 35 years at the time of diagnosis. Proctitis was found in 57%, left-sided colitis in 12%, and substantial or total colitis in 31%. Relapse at pregnancy was demonstrated in seven patients, and remission in one. Family history of a first-degree relative with inflammatory bowel disease was documented in three patients (2%). Probable complications of ulcerative colitis were observed in 38 (26%), anemia in 13 (9%). One patient (0.7%) with rectal cancer, also had breast cancer. We suggest that the impressive increase in ulcerative colitis prevalence among Israeli and Asian-African-born, in comparison with European-American-born kibbutz members, points toward a role of environmental factors in the etiology of this disease.

A 7-year-old girl with hypereosinophilic syndrome is described, the first such patient to present with inflammatory bowel disease. Hepatosplenomegaly, anaemia, and hypergammaglobulinaemia were also prominent features. Colonoscopy revealed a frank colitis of nonspecific histologic appearance. An elemental diet was unhelpful, but there was a prompt clinical and partial haematological response to systemic steroids. She has remained well receiving a small maintenance dose of prednisolone for 3 years.

A total of 212 adult patients with infective diarrhoea and 27 with inflammatory bowel disease (IBD), admitted consecutively to an infectious disease unit, were studied in order to determine whether clinical features and laboratory measurements performed on admission identified cases of IBD. Long-standing diarrhoea, blood in the faeces, anaemia, leucocytosis, thrombocytosis, raised ESR and a reduced concentration of serum albumin were more common in patients with IBD (P less than 0.05). The most striking difference was in the platelet count with 59% patients with IBD and 1.6% patients with infective diarrhoea having platelet counts greater than 450 x 10(9)/l. A raised platelet count in a patient admitted to hospital with 'acute gastro-enteritis' suggests IBD.

The aim of the study was to evaluate the indications of colonoscopy, diagnostic accuracy and efficacy treatment of procedure in young patients aged less than eighteen years using standard forward colonoscopes Olympus CF LB2, CF LBw and CF HL20. Among 5,400 procedures done along eleven years, 112 (2.07 per 100) were performed in patients aged less than eighteen years, 37.6 per 100 of which were performed in children under ten years. In this group general anaesthesia was employed without complications. The most frequent indication of colonoscopy in young patients was rectal bleeding (62.5 per 100). Related to the frequency, in this series, the control of graft versus host disease in patients submitted to bone marrow transplantation was the second indication (11 per 100), followed by the study of chronic anaemia (4.2 per 100) and control of the chronic inflammatory bowel disease (4.2 per 100). Diagnostic accuracy reached 93.75 per 100. In 6 per 100 of the cases the exploration were considered unsatisfactory because inadequate cleaning of the colon. The most frequent diagnostic was "normal colon" (29.6 per 100 of the cases). Polyp was found in 21.2 per 100 of the cases. Polypectomy was performed in all indicated cases. One patient with multiple polyposis were submitted to surgery. Colonoscopy reached the right colon in 25.4 per 100 of the cases. In 54 per 100 of the procedures reached splenic angle and in 83.8 per 100 of the cases, all sigmoid colon was explored. From this experience we suggests that colonoscopy, using standard endoscopes, is a very useful diagnostic and therapeutic technique in child and in young people.(ABSTRACT TRUNCATED AT 250 WORDS)

Sulfasalazine, a commonly prescribed drug for the treatment of inflammatory bowel disease, can cause an allergic reaction with hepatotoxicity, lymphadenopathy, and rash. In addition, many hematologic complications have been observed with sulfasalazine, including aplastic anemia, thrombocytopenia, and erythroid hypoplasia. However, thrombocytopenia in association with sulfasalazine hypersensitivity has not been previously reported. We report a child who developed severe thrombocytopenia and anemia during a hypersensitivity reaction to sulfasalazine.

Four cases of giant inflammatory polyps were found in a series of 86 consecutive colectomies for inflammatory bowel disease. Two presented a distinctive clinical syndrome of abdominal pain and chronic iron-deficiency anemia due to blood loss. Secondary ulceration of the heads of the polyps accounted for the bleeding and anemia, and the size of the polyps accounted for the abdominal pain. In both cases unusually long portions of colon were involved by the giant polyps. The third and fourth cases had rare complications--reactivation of an enterocutaneous fistula and perforation of an acquired diverticulum. These cases demonstrate that giant inflammatory polyps may produce symptoms independently of the underlying inflammatory bowel disease. In reported cases of giant inflammatory polyps, approximately two-thirds had Crohn's disease and one-third had ulcerative colitis. The transverse colon was the commonest location, pain was the commonest symptom, and the polyps were localized to a short segment of colon in the majority of cases. More than 50% of cases mimicked neoplasm on barium enema. Giant inflammatory polyps may produce a variety of distinctive signs and symptoms and deserve independent recognition.
