Ineffectiveness of Lactobacillus johnsonii LA1 for prophylaxis of postoperative recurrence in Crohn's disease: a randomised, double blind, placebo controlled GETAID trial.

Background and aims: Early endoscopic recurrence is frequent after intestinal resection for Crohn’s disease. Bacteria are involved, and probiotics may modulate immune responses to the intestinal flora. Here we tested the probiotic strain Lactobacillus johnsonii LA1 in this setting. Patients and methods: This was a randomised, double blind, placebo controlled study. Patients were eligible if they had undergone surgical resection of <1 m, removing all macroscopic lesions within the past 21 days. Patients were randomised to receive two packets per day of lyophilised LA1 (2×109 cfu) or placebo for six months; no other treatment was allowed. The primary endpoint was endoscopic recurrence at six months, with grade >1 in Rutgeerts’ classification or an adapted classification for colonic lesions. Endoscopic score was the maximal grade of ileal and colonic lesions. Analyses were performed primarily on an intent to treat basis. Results: Ninety eight patients were enrolled (48 in the LA1 group). At six months, endoscopic recurrence was observed in 30/47 patients (64%) in the placebo group and in 21/43 (49%) in the LA1 group (p = 0.15). Per protocol analysis confirmed this result. Endoscopic score distribution did not differ significantly between the LA1 and placebo groups. There were four clinical recurrences in the LA1 group and three in the placebo group. Conclusion:L johnsonii LA1 (4×109 cfu/day) did not have a sufficient effect, if any, to prevent endoscopic recurrence of Crohn’s disease.

Metabolic bone assessment in patients with inflammatory bowel disease

BACKGROUND/AIMS Patients with inflammatory bowel disease are at risk for osteopenia. To study the metabolic bone status of these patients, a cross-sectional study was conducted. METHODS Eighty-four patients (49 women, 35 men) with inflammatory bowel disease, 34 of whom had Crohns disease and 50 ulcerative colitis (including 18 with prior coloproctectomy and ileoanal anastomosis), underwent clinical, dietary, and spine radiological assessments. Bone metabolism was assessed by measuring serum levels of calcium, phosphate, parathyroid hormone (1-84), 25-hydroxyvitamin D3, 1,25-dihydroxyvitamin D3, and osteocalcin. Lumbar and femoral neck bone mineral densities were measured by dual energy X-ray absorptiometry. RESULTS Serum osteocalcin level was decreased in 29 patients (34%), 12 of whom had never undergone steroid therapy. The other biochemical markers of bone metabolism were in the normal range. Thirty-six patients (43%) had osteopenia, and 6 patients (7%) had vertebral crush fractures. Osteopenia was observed in 27 patients (52%) and 9 patients (28%) with and without corticosteroid therapy, respectively. No patient had clinical or biological signs of osteomalacia. Analysis of bone density (lumbar Z score) by a multiple regression analysis showed a statistically significant correlation with age, cumulative corticosteroid doses, sedimentation rate, and osteocalcin level (R2 = 0.76; P = 0.05). CONCLUSIONS The results suggest that bone turnover in inflammatory bowel disease is characterized by low bone formation in the presence of normal levels of calcium-regulating hormones.

Osteoporosis in inflammatory bowel disease: effect of calcium and vitamin D with or without fluoride

Previous data have indicated low bone formation as a mechanism of osteoporosis in inflammatory bowel disease. Fluoride can stimulate bone formation.

Excess risk of urinary tract cancers in patients receiving thiopurines for inflammatory bowel disease: a prospective observational cohort study.

The risk of urinary tract cancers, including kidney and bladder cancers, was increased in transplant recipients receiving thiopurines.

Iron deficiency: From diagnosis to treatment

Iron deficiency is the most frequent cause of anaemia worldwide. It impairs quality of life, increases asthenia and can lead to clinical worsening of patients. In addition, iron deficiency has a complex mechanism whose pathologic pathway is recently becoming better understood. The discovery of hepcidin has allowed a better clarification of iron metabolism regulation. Furthermore, the ratio of concentration of soluble transferrin receptor to the log of the ferritin level, has been developed as a tool to detect iron deficiency in most situations. The cause of iron deficiency should always be sought because the underlying condition can be serious. This review will summarize the current knowledge regarding diagnostic algorithms for iron deficiency anaemia. The majority of aetiologies occur in the digestive tract, in men and postmenopausal women, and justify morphological examination of the gut. First line investigations are upper gastrointestinal endoscopy and colonoscopy, and when negative, the small bowel should be explored; newer tools such as video capsule endoscopy have also been developed. The treatment of iron deficiency is aetiological if possible and iron supplementation whether in oral or in parenteral form. New parenteral formulations are available and seem to have promising results in terms of efficacy and safety.

One-year effectiveness and safety of vedolizumab therapy for inflammatory bowel disease: a prospective multicentre cohort study

We recently showed that vedolizumab is effective in patients with Crohns disease (CD) and ulcerative colitis (UC) with prior anti‐TNF failure in a multicentre compassionate early‐access programme before marketing authorisation was granted to vedolizumab.

Diagnostic delay in a French cohort of Crohn's disease patients

UNLABELLED Diagnostic delay is frequent in Crohns disease (CD) and may partly depend on socioeconomic status. The aim of this study was to determine the diagnostic delay and to identify associated risk factors, including socioeconomic deprivation in a French cohort of CD patients. METHODS Medical and socioeconomic characteristics of all consecutive CD patients followed in 2 referral centers between September 2002 and July 2012 were prospectively recorded using an electronic database. Diagnostic delay was defined as the time period (months) from the first symptom onset to CD diagnosis. A long diagnostic delay was defined by the upper quartile of this time period. Univariate and multivariate analyses were performed to identify the baseline characteristics of patients associated with a long diagnostic delay. RESULTS Three hundred and sixty-four patients with CD (mean age=29.2±12.6 years, 40.8% men) were analyzed. Median diagnostic delay was 5 months, and a long diagnostic delay was more than 12 months. Fifty-six patients (15.3%) had perianal lesions, and 28 patients (8.6%) had complicated disease at diagnosis. None of the following factors were associated with a long diagnostic delay: age, gender, CD location and behavior, marital and educational, language understanding, geographic origin and socioeconomic deprivation score measured by the EPICES score. CONCLUSION In this French referral center-based cohort of CD patients, the median diagnostic delay was 5 months. None of the baseline characteristics of the CD, including socioeconomic deprivation, influenced diagnostic delay in this cohort.

Portomesenteric Vein Thrombosis in Patients With Inflammatory Bowel Disease.

Background:Inflammatory bowel disease (IBD) is associated with a high risk of deep venous thromboembolism. However, few data are available so far on portomesenteric vein thrombosis (PMVT). The aim of this study was to describe the characteristics of PMVT in patients with IBD. Methods:A retrospective study was conducted at 13 GETAID (Groupe d’Etude Thérapeutique des Affections Inflammatoires du Tube Digestif) centers from January 1995 to June 2010. The following data were collected, using a standardized questionnaire: characteristics of IBD, disease status at the time of PMVT, PMVT characteristics and mode of discovery, concomitant prothrombotic disorders, anticoagulant therapy, and evolution of PMVT. Results:Fifty cases (29 men and 21 women; median age, 41 years) were identified, including 14 patients with ulcerative colitis and 36 with Crohns disease. Thirty-one patients (62%) presented with acute PMVT. Twenty-four patients had previously undergone surgical treatment, and IBD was active in 23 cases (77%) of acute thrombosis. The discovery of PMVT was fortuitous in 40% of our cases. Among the 43 patients screened for a prothrombotic disorder, abnormalities were observed in 17 patients (40%) (mainly hyperhomocysteinemia, n = 12). Forty-four patients (88%) were treated with anticoagulants. Recanalization of the vein was significantly more successful in patients with acute thrombosis (65% versus 37%, P = 0.05). Conclusions:PMVT can occur when IBD is inactive, and its diagnosis was fortuitous in 40% of our cases. Screening for prothrombotic disorders is essential because it is positive in more than one third of cases.

Negative Screening Does Not Rule Out the Risk of Tuberculosis in Patients with Inflammatory Bowel Disease Undergoing Anti-TNF Treatment: A Descriptive Study on the GETAID Cohort

AIM to describe the characteristics of incident cases of tuberculosis [TB] despite negative TB screening tests, in patients with inflammatory bowel disease [IBD] undergoing anti-TNF treatment, and to identify the risk factors involved. METHODS A retrospective descriptive study was conducted at GETAID centers on all IBD patients undergoing anti-TNF treatment who developed TB even though their initial screening test results were negative. The following data were collected using a standardized anonymous questionnaire: IBD, and TB characteristics and evolution, initial screening methods and results, and time before anti-TNF treatment was restarted. RESULTS A total of 44 IBD patients [including 23 men; median age 37 years] were identified at 20 French and Swiss centers at which TB screening was performed [before starting anti-TNF treatment] based on Tuberculin Skin Tests [n = 25], Interferon Gamma Release Assays [n = 12], or both [n = 7]. The median interval from the start of anti-TNF treatment to TB diagnosis was 14.5 months (interquartile range [IQR] 25-75: 4.9-43.3). Pulmonary TB involvement was observed in 25 [57%] patients, and 40 [91%] had at least one extrapulmonary location. One TB patient died as the result of cardiac tamponade. Mycobacterium tuberculosis exposure was thought to be a possible cause of TB in 14 cases [32%]: 7 patients [including 6 health care workers] were exposed to occupational risks, and 7 had travelled to endemic countries. Biotherapy was restarted on 27 patients after a median period of 11.2 months [IQR 25-75: 4.4-15.2] after TB diagnosis without any recurrence of the infection. CONCLUSION Tuberculosis can occur in IBD patients undergoing anti-TNF treatment, even if their initial screening results were negative. In the present population, TB was mostly extrapulmonary and disseminated. TB screening tests should be repeated on people exposed to occupational risks and/or travelers to endemic countries. Restarting anti-TNF treatment seems to be safe.

Impact of complementary and alternative medicine on the quality of life in inflammatory bowel disease: results from a French national survey.

Background Complementary and alternative medicines (CAM) are widely used by patients with inflammatory bowel disease (IBD). Few data have been published on the impact of CAM on the quality of life (QOL). Aims The aim of the study was to describe CAM use in French patients with IBD, identify characteristics associated with CAM use, and assess the impact of CAM on the QOL. Methods We conducted an internet survey on CAM through the French IBD patient’s association website. Patients had to answer a questionnaire (LimeSurvey application) about sociodemography, IBD treatment, CAM type, socioeconomic data, and QOL using the Short IBD Questionnaire (SIBDQ). Patients noted the impact of CAM on their symptoms and on their QOL on a scale of 0–100. CAM users and nonusers were compared by univariate and multivariate analyses. Results A total of 936 IBD patients responded and 767 (82.4%) filled up the whole questionnaire: 503 reported CAM use and 172 had never used. The types of CAM reported were diet-based (30.7%), body-based (25.1%), homeopathic or traditional medicine (19.6%), naturopathy (15.2%), and mind–body medicine (9.1%). The gastroenterologist was aware of CAM use in only 46% of patients. CAM users were more likely to have ulcerative colitis [odds ratio (OR)=1.78, P=0.018], clinical remission (OR=1.42, P=0.06), high level of education (OR=1.51, P=0.02), poor observance (OR=1.81, P=0.017), or to have terminated conventional treatment (OR=2.03, P=0.003). CAM users tend to have higher rates of SIBDQ scores, greater than 50 (OR=1.57, P=0.06). Improvement in symptoms and QOL was reported with all CAM types except mind medicine. Conclusion CAM use is widespread among IBD patients. CAM users report improvement in symptoms and QOL, but they tend to stop their conventional treatment. Better information about CAM might improve adherence to conventional treatment.
