A controlled trial comparing ciprofloxacin with mesalazine for the treatment of active Crohn's disease. Groupe d'Etudes Thérapeutiques des Affections Inflammatoires Digestives (GETAID).

OBJECTIVE: The aim of this randomized controlled study was to investigate the efficacy of ciprofloxacin compared with mesalazine in treating active Crohn's disease. METHODS: Patients with a mild to moderate flare-up of Crohn's disease (mean Crohn's Disease Activity Index [CDAI]; 217; range, 160-305) were randomized to receive ciprofloxacin 1 g/day or Pentasa 4 g/day for 6 wk. Complete remission was defined at wk 6 as a CDAI < or = 150 associated with a decrease (delta) in CDAI > 75. Partial remission was defined as a CDAI < or = 150 with 50 < delta CDAI < 75 or a CDAI > 150 with delta CDAI > 50 at wk 6. Group sequential procedure with triangular continuation regions was used to monitor the trial through the difference in complete remission rates, every 20 patients included. RESULTS: Inclusion of patients was stopped at the second step, i.e., after 40 inclusions, with the conclusion of no difference in complete remission rates between ciprofloxacin- and Pentasa-treated groups. Among the 18 patients taking ciprofloxacin, two decided to stop treatment during the trial and three were considered as treatment failures because of deterioration at wk 3. Among the 22 patients taking mesalazine, one patient was lost to follow-up and eight patients were considered as treatment failures. Complete remission was observed in 10 patients (56%) treated with ciprofloxacin and 12 patients (55%) treated with mesalazine and partial remission was observed in three and one patient, respectively. CONCLUSIONS: This study suggests that ciprofloxacin 1 g/day is as effective as mesalazine 4 g/day in treating mild to moderate flare-up of Crohn's disease.

[Diagnostic and therapeutic management of patients with chronic inflammatory bowel disease].

BACKGROUND: The period of time required for the diagnosis of a chronic illness depends on initial clinical symptoms and their perception by the patient and the physicians. The aim of this study was to describe the procedures of diagnosis of incident cases of Inflammatory Bowel Disease (IBD). METHODS: Patients reported by the Registry of inflammatory bowel disease of northern France (EPIMAD) in 1994 were included. Standardized questionnaires describing clinical history, patient behavior, medical consultations and examinations were collected by an interviewer practitioner from three sources: patients, general practitioners (GP) and gastroenterologists (GE). Patients were divided in 2 groups according to the time between symptom onset and diagnosis: more than 9 months or less than 9 months (D > 9 and D < or = 9). RESULTS: 258 patients were included: 144 Crohn's disease (CD) (56%), 106 ulcerative colitis (UC) (41%) and 8 chronic unclassifiable colitis (CUC). Median time between symptom onset and diagnosis was 3 months, 196 (76%) patients belonged to the group D < or = 9 and 62 (24%) to the group D > 9. There was no difference between the 2 groups for initial clinical symptoms. The delay between symptom onset and the consultation to the GP and the GE was longer in the group D > 9: respectively 1 month vs 0 and 7.6 vs 2. Thirty-five percent of patients in the group D > 9 had consulted more than one GP vs 14% (p < 0.05). Diagnosis management by the GE was the same in both groups. Patients of group D < or = 9 had more often perceived their symptoms as serious (p < 0.05). CONCLUSIONS: Delay to diagnosis in a quarter of patients with IBD was more than 9 months. This later diagnosis was not due to patient management by the GE but rather to a longer delay to consulting the GP and between GP and GE referral. Patient interpretation of the symptoms could also explain the variability of this delay.

[Cost of early management of chronic inflammatory intestinal disease].

OBJECTIVES: The aim of this study was to assess the cost of the first management of inflammatory bowel disease (IBD) from the onset of first symptoms until 6 weeks after the diagnosis. This cost was calculated in French francs (FF) for all IBD and namely for Crohn's disease (CD), ulcerative colitis (UC), and ulcerative proctitis (UP). MATERIAL AND METHODS: Data concerning 258 patients were collected by the mean of a standardized questionnaire from 3 different sources: the patient, his general practitioner, and his gastroenterologist. RESULTS: Two hundred and fifty eight patients were included: 144 CD (55.8%), 76 UC (29.5%), 30 UP (11.6%), and 8 chronic unclassifiable colitis (CUC) (3.1%). The mean direct costs of the diagnosis (m +/- SD) were 23,116 +/- 40,820 FF for CD, 10,628 +/- 17,316 FF for UC and 3,451 +/- 2,743 FF for UP. Although unplanned hospitalizations occurred in only 38% of the patients (98/258), they represented the 3/4 of the mean costs: 78.2% for CD and 64% for UC. Indirect costs generated by days off work were 4,719 +/- 6,610 FF for CD, 2,996 +/- 6,897 FF for UC and 1,230 +/- 3,622 FF for UP. CONCLUSION: The first management of a patient with CD was twice more expensive than the one with UC and 6.5 times than the one with UP.

[Clinical course of symptomatic duodeno-jejunal Crohn's disease].

AIMS: To describe retrospectively the characteristics of inaugural, symptomatic Crohn's disease of the upper gastrointestinal tract. METHODS: Eighteen patients (12 male and 6 female) with symptomatic Crohn's disease of the upper intestinal tract and without previous distal localisation were studied. RESULTS: Mean age of patients at diagnosis (21.3 years) was less than that usually reported in Crohn's disease. The time elapsed from first symptoms to diagnosis (mean = 29.8 months) was remarkably long for some patients, mainly as a result of an unusual clinical presentation. Abdominal pain and weight loss were the most common presenting features; diarrhea was rarely the main symptom. Persistent anorexia and weight loss without digestive symptoms had led to a diagnosis of anorexia nervosa in 4 patients. Zollinger-Ellison syndrome was the initial diagnosis in 3 other patients. Sixteen patients were followed during at least 2 years. All were treated with steroids for their first attack and 75 % required immunosuppressive therapy for steroid dependence. At the end of follow-up, 6 patients only were in remission without treatment or under mesalamine. CONCLUSION: Crohn's disease with initial symptomatic lesions of the upper gastrointestinal tract occurs mainly in young male patients. The clinical presentation may be very unusual, leading to misdiagnosis. The clinical course is close to that of diffuse jejunoileitis.

[Hemorrhaging eso-gastro-duodenal ulcers: epidemiology and management. A multicenter prospective study].

UNLABELLED: The aim of this study was to estimate the incidence, and to describe the characteristics and medical care in patients with bleeding upper gastrointestinal ulcers in the general population. PATIENTS AND METHODS: A study was performed over six months in 1996 in 4 French geographical areas: Finistère, Gironde, Seine-Maritime, and the Somme (3 million people minimum 18 years). All public or private hospitals, and specialist gastroenterologists in private practice participated in the study, based on a standardized questionnaire. RESULTS: Over 6 months 793 patients with bleeding ulcers were identified, corresponding to 27 per 100,000 inh./year or 24,000 cases in France. Most patients were men (60%) and 40.1% were 75 years and older. The ulcer was oesophageal (6%), gastric (47%), or duodenal (69%). In 406 patients (51.2%) a chronic disease was present (cancer, cirrhosis, circulatory, respiratory or cardiac disease). In 237 cases (29.9%) the ulcer occurred in patients, 453 patients (57.1%) were admitted and 103 patients (13%) were managed as outpatients. Gastrotoxic drugs were taken by 349 patients (44%): non steroidal anti-inflammatory drugs (18.7%), aspirin (21.2%, including 2/3 with doses under 330 mg/day), corticosteroids (7.8%) and 24.3% had anticoagulant therapy. Patients were managed in university hospitals (39.3%), other public or non profit hospitals (44.2%) or private hospital (16.5%) with geographical differences between the 4 areas. Therapeutic endoscopy was performed in 16.9% and a surgical procedure was performed in 5.9%. The mortality rate (outpatients excluded) was 13.5% (n = 93), but only 2% (n = 16) of death were associated with a bleeding ulcer: mortality was higher in inpatients (24.1%) than in out patients (8.1%). A chronic disease was also associated with higher mortality (17.9% versus 8.1%). CONCLUSION: Bleeding ulcers are frequent and severe, especially in inpatients or associated with chronic conditions. A gastrotoxic drug used is found in about fifty percent of the cases.

[Percutaneous cholecystostomy. A study of 30 patients].

OBJECTIVE AND METHODS: The treatment of acute cholecystitis or angiocholitis is often difficult in elderly or very ill patients. The aim of this retrospective study was to assess the efficacy and the results of ultrasound guided percutaneous cholecystostomy in patients with acute cholecystitis or biliary tract obstruction and anesthetic or surgical contraindications. RESULTS: Thirty patients (25-93 years, 16 men and 14 women) were included in this study. Ultrasound guided percutaneous cholecystostomy was successful on the septic syndrome in 27 patients; endoscopic sphincterotomy was performed in 6 patients after clinical improvement. A failure of the procedure on sepsis was observed in 3 patients: cholecystectomy was performed after cardiac improvement in one patient, and 2 patients died. Two other patients died of extradigestive diseases. No serious complication related to cholecystostomy was observed. CONCLUSION: Ultrasound guided percutaneous cholecystostomy is a safe and simple procedure. It can be done at bedside and has low morbidity and mortality. It can be considered as a definitive treatment, or a temporary one with secondary surgical or endoscopic management.

[Chemical colitis caused by glutaraldehyde].

Glutaraldehyde disinfectant solution may be a cause of toxic chemical colitis. We report two cases. Ultrasonic features were studied in one case and mimic colonic ischemia, inflammatory and/or infectious colitis. These findings were colonic wall thickening especially mucosal (hypoechogenicity) and submucosal (hyperechogenicity) layers. This diagnosis should be discussed when one sees a patient with echographic findings of acute left-sided colitis just after uncomplicated colonic endoscopy.

Mapping of a susceptibility locus for Crohn's disease on chromosome 16.

Crohn's disease (CD) and ulcerative colitis are the major forms of chronic inflammatory bowel diseases in the western world, and occur in young adults with an estimated prevalence of more than one per thousand inhabitants. The causes of inflammatory bowel diseases remain unknown, but genetic epidemiology studies suggest that inherited factors may contribute in part to variation in individual susceptibility to Crohn's disease. A genome-wide search performed on two consecutive and independent panels of families with multiple affected members, using a non-parametric two-point sibling-pair linkage method, identified a putative CD-susceptibility locus on chromosome 16 (P less than 0.01 for each panel). The localization was centered around loci D16S409 and D16S419 by using multipoint sibpair analysis (P less than 1.5x10(-5)). This region of the genome contains candidate genes which may be relevant to the pathogenic mechanism of inflammatory bowel diseases.

[Treatment of metastatic carcinoid tumors with interferon-alpha. Five cases].

OBJECTIVE: Interferon has been proposed in treatment of metastatic carcinoid tumours with varied results. METHOD: Five patients with metastatic carcinoid tumours were treated for 1 year with rIFN alpha 2b at a dose of 5 MU. three times a week during the first month and 10 MU. three times a week during the following months. Carcinoid syndrome was present in all cases. RESULTS: Clinical response with improvement of diarrhoea and flushs was obtained in all cases. Urinary excretion of 5 HIAA and blood serotonin were reduced in 2/5 and 4/5 patients respectively. IFN treatment led to a stabilization of the metastatic tumour in all cases. Recurrence of symptoms was observed within three months following the end of the IFN treatment. CONCLUSION: These findings confirm the contribution of IFN in the treatment of metastatic carcinoid tumours.

Mesalamine in Crohn's disease with steroid-induced remission: effect on steroid withdrawal and remission maintenance, Groupe d'Etudes Thérapeutiques des Affections Inflammatoires Digestives.

BACKGROUND & AIMS: Steroid dependence and early relapse are frequent after a prednisolone-induces remission in Crohn's disease. The aim of this trial was to test whether mesalamine started at the onset of steroid tapering increases the rate of weaning from prednisolone and reduces the relapse rate after prednisolone cessation. METHODS: One hundred fifty patients with active Crohn's disease were administered oral prednisolone (1 mg.kg(-1). day(-1)) x 3-7 weeks; 129 patients went into clinical remission and were randomized to Pentasa (4 g . day(-1)) or placebo, administered until weaning and for 1 year thereafter. RESULTS: Groups were similar for clinical and biological items collected initially. Weaning failure rate was 30% and 12% in the placebo and mesalamine arms, respectively. At the end of the trial, 9 of 36 patients administered placebo and 14 of 48 administered mesalamine were in remission. Both groups had similar time to relapse curves in the postweaning year; after adjusting for risk factors (high Crohn's Disease Activity Index, white blood cell count of >9 x 10(9) /l-1 at weaning, and use of a medical treatment in the month before inclusion), Pentasa was found to be superior to placebo. CONCLUSIONS: After a prednisolone-induces remission in Crohn's disease, mesalamine facilitates steroid withdrawal and, during the postweaning year, may reduce the relapse rate in certain patient subgroups.

Clinical characteristics of Crohn's disease in 72 families.

BACKGROUND & AIMS: Familial aggregation argues for genetic susceptibility to Crohn's disease. The aim of this study was to compare the age of onset and the clinical features of Crohn's disease between patients with familial disease and those with sporadic disease and investigate the concordance for disease location and type among relatives with Crohn's disease. METHODS: Seventy-two families with 2 (n = 55), 3 (n = 8), 4 (n = 6), and 5 or more (n = 3) affected first-degree relatives were selected for the study. A population of 1377 patients with sporadic nonfamilial Crohn's disease was used for comparison. RESULTS: Clinical data were obtained from 176 patients with familial Crohn's disease (79 men and 97 women). Median age at onset was younger in familial Crohn's disease than in sporadic cases: 22 vs. 26.5 years (P < 0.01). In familial cases, fewer patients had exclusively colonic involvement and more patients had both small bowel and colonic involvement. Among relatives of families with 2 affected members, 56% were concordant for disease location and 49% for disease type. These percentages reached 83% and 76%, respectively, within families with more than 2 affected members. CONCLUSIONS: Patients with familial Crohn's disease are characterized by an early age at onset with more extensive disease and may represent a homogeneous clinical subgroup with a particularly strong genetic influence.

Placebo-controlled clinical trial of mesalazine in the prevention of early endoscopic recurrences after resection for Crohn's disease. Groupe d'Etudes Thérapeutiques des Affections Inflammatoires Digestives (GETAID).

OBJECTIVE: Endoscopic postoperative recurrences occur early after 'curative' surgery for Crohn's disease. Pentasa has been shown to be effective in the maintenance treatment of quiescent Crohn's disease. The aim of this study was to test the efficacy of a 12-week oral intake of Claversal in the prevention of endoscopic recurrences after 'curative' resection for ileal, colonic or ileocolonic Crohn's disease. We conducted a multicentre double-blind controlled trial comparing Claversal (1g tid) with placebo, starting within 15 days after surgery. The macroscopic normality of the two anastomotic segments was assessed at surgery. Patients were clinically and biologically evaluated twice (6-week interval), and colonoscopy was performed at 12 weeks. Endoscopic relapse was defined by any anastomotic ulcerations or stenosis and staged according to a four-grade score. RESULTS: Between May 1989 and May 1991 12 centres included 126 patients, 70 women and 56 men, aged 33 +/- 12 years (range 16-70) in the study. Disease locations were ileal, colonic and ileocolonic in 45, 6 and 49%, respectively. Claversal and placebo groups were similar at inclusion, except for ESR (37 +/- 26 vs. 27 +/- 23 mm/h in the Claversal and placebo groups, respectively; P < 0.05). Nine patients were withdrawn from the study. Adverse reactions occurred only in six patients. Five patients were excluded for protocol violation. Finally, 106 patients could be evaluated at 12 weeks (55 Claversal and 51 placebo). An endoscopic relapse was observed in 50% and 63% of the Claversal and placebo groups, respectively (P = 0.16), with a similar grade distribution. Claversal was well tolerated. CONCLUSIONS: Our study confirms that a large proportion of endoscopic recurrences occur within 3 months of resection in Crohn's disease. There was a slight trend towards greater efficacy of Claversal; it could be worthwhile trying higher dosages and/or 5-ASA compounds with different intestinal release profiles.

Treatment of the carcinoid syndrome with the longacting somatostatin analogue lanreotide: a prospective study in 39 patients.

BACKGROUND: Somatostatin analogues effectively control flushing and diarrhoea in patients with the carcinoid syndrome. The octapeptide lanreotide is available in slow release form, which could eliminate the necessity of twice a day injections as with octreotide. PATIENTS AND METHODS: 39 patients with carcinoid syndrome were included in a prospective multicentre study. Patients received lanreotide 30 mg intramuscularly every 14 days for six months. The number and intensity of flushing episodes and bowel movements, urinary 5 hydroxy-indolacetic acid (5 HIAA) concentrations, and variations of tumour mass were recorded. RESULTS: After one month of treatment, flushing episodes (median (range)) decreased significantly (3 (0.3-24) episodes per day v 1 (0-15), p = 0.04) and completely resolved in 39% of the patients. A significant decrease was seen in the number of bowel movements and discomfort related to diarrhoea. Urinary 5 HIAA concentrations were unchanged in 57% of the patients and decreased in 18%. After six months of treatment, the actuarial proportions of patients with at least a 50% decrease in the number of flushing episodes and bowel movements were 54% and 56%, respectively. Forty two per cent of the patients who were treated for six months had at least a 50% reduction in 5 HIAA values. No clear signs of regression of tumours were seen in any of the patients. Lanreotide was well tolerated despite transient mild pain or erythema at the injection site in 25% of the patients. Biliary lithiasis appeared in two patients after six months of lanreotide. CONCLUSION: Lanreotide, 30 mg intramuscularly every other week, is an effective and convenient treatment in patients with the carcinoid syndrome.

[Helicobacter pylori and gastroduodenal lesions in 547 symptomatic young adults].

OBJECTIVES: Helicobacter pylori (H. pylori) is involved in the pathogenesis of gastric inflammatory disorders. Both antral chronic gastritis and H. pylori infection prevalence increase with age. The aim of the study was to assess the prevalence of H. pylori infection in young adults and to study the relationship between endoscopical and histological features and H. pylori infection. METHODS: The study concerned 547 young patients (age: 18-25 years), undergoing endoscopy for upper gastrointestinal symptoms. The severity and the activity of chronic gastritis was graded by histological examination of antral biopsies. The diagnosis of H. pylori infection was based on histology and culture or urease test. RESULTS: Fifty-three percent of the patients had a normal endoscopy; 44 ulcers were found: 34 duodenal ulcers and 10 gastric ulcers. H. pylori infection was detected in 34% of cases. The prevalence of H. pylori infection was 29.8% in non-ulcer patients, 50% in gastric ulcers and 91% in duodenal ulcers (P < 0.01). Duodenal ulcer, aspect of antral mosaic mucosa and nodular gastritis, were closely related to the presence of H. pylori. There was a significant relationship between H. pylori infection and both the severity (P < 0.01) and the activity (P < 0.01) of the antral chronic gastritis. The prevalence of follicular gastritis was 22% : it was present in 60% of H. pylori positive patients and 2.4% of H. pylori negative patients. H. pylori infection was more frequent in patients from Africa than in Europeans (P < 0.01). There was no significant association between H. pylori infection and different types of diets, settlements (rural vs urban) or symptoms. CONCLUSION: These results show that in the young population studied, duodenal ulcer, nodular gastritis, antral mosaic mucosa, active chronic gastric and follicular gastritis are closely related to H. pylori infection. They suggest that in the subgroup of non ulcer symptomatic patients, H. pylori prevalence is higher than in the general population.

Fibrotic stricture of the extrapancreatic biliary tract: a new complication of acute pancreatitis. Two cases.

Two cases of fibrotic stricture of the extrapancreatic common bile duct were observed 3 and 5.5 months after severe acute alcoholic pancreatitis. The diagnosis was made by endoscopic retrograde cholangiography in both cases. Although colonic or ureteric stenosis have been reported after acute pancreatitis, this is the first report of extrapancreatic biliary stricture occurring after acute pancreatitis. The strictures could have arisen by either an enzymatic or ischemic mechanism. Outcome was favorable after surgical hepaticojejunostomy.
