Summary
Background
Women with inflammatory bowel diseases (IBD) often receive biologicals during pregnancy to maintain disease remission. Data on outcome of vedolizumab‐exposed pregnancies (VDZE) are ...sparse.
Aims
To assess pregnancy and child outcomes of VDZE pregnancies and to compare these results to anti‐TNF exposed (TNFE) or both immunomodulatory and biologic unexposed (CON IBD) pregnancies.
Methods
A retrospective multicentre case‐control observational study was performed.
Results
VDZE group included 79 pregnancies in 73 IBD women. The TNFE and CON IBD group included 186 pregnancies (162 live births) in 164 IBD women and 184 pregnancies (163 live births) in 155 IBD women, respectively. At conception, cases more often had active disease (VDZE: 36% vs TNFE: 17%, P = .002 and VDZE: 36% vs CON IBD: 24%, P = .063). No significant difference in miscarriage rates were found between groups (VDZE and TNFE: 16% vs 13%, P = .567; VDZE and CON IBD: 16% vs 10%, P = .216). In live‐born infants, median gestational age and birthweight were similar between groups. Median Apgar score at birth was numerically equal. Prematurity was similar in the VDZE group compared to the control groups, even when correcting for disease activity during pregnancy. The frequency of congenital anomalies was comparable between groups as were the percentages of breastfed babies. During the first year of life, no malignancies were reported and infants' infection risk did not significantly differ between groups.
Conclusion
No new safety signal was detected in VDZE pregnancies although larger, prospective studies are required for confirmation.
Between 20 to 25% of Crohn’s disease (CD) patients suffer from perianal fistulas, a marker of disease severity. Seton drainage combined with anti-TNFα can result in closure of the fistula in 70 to ...75% of patients. For the remaining 25% of patients there is room for in situ injection of autologous or allogenic mesenchymal stem cells such as adipose-derived stem/stromal cells (ADSCs). ADSCs exert their effects on tissues and effector cells through paracrine phenomena, including the secretome and extracellular vesicles. They display anti-inflammatory, anti-apoptotic, pro-angiogenic, proliferative, and immunomodulatory properties, and a homing within the damaged tissue. They also have immuno-evasive properties allowing a clinical allogeneic approach. Numerous clinical trials have been conducted that demonstrate a complete cure rate of anoperineal fistulas in CD ranging from 46 to 90% of cases after in situ injection of autologous or allogenic ADSCs. A pivotal phase III-controlled trial using allogenic ADSCs (Alofisel®) demonstrated that prolonged clinical and radiological remission can be obtained in nearly 60% of cases with a good safety profile. Future studies should be conducted for a better knowledge of the local effect of ADSCs as well as for a standardization in terms of the number of injections and associated procedures.
INTRODUCTION:
The objective of this study was to describe the efficacy and safety of infliximab (IFX) reintroduction in Crohn's disease (CD) after stopping for loss of response or intolerance.
...METHODS:
We conducted a prospective multicenter observational cohort study including adult patients with clinically (CD Activity Index >150) and objectively active luminal CD in whom IFX was reintroduced after at least 6 months of discontinuation. The reasons for the initial discontinuation could be a secondary loss of response or IFX intolerance. The reintroduction schedule included 3 IFX infusions at weeks 0, 4, and 8, after a systematic premedication. The primary end point was the efficacy of IFX retreatment at week 26 defined by a CD Activity Index of <150 in the absence of IFX discontinuation or use of corticosteroids, surgery, or other biologic.
RESULTS:
At week 26, 24 patients (35%) among the 69 analyzed reached the primary end point. No significant difference was observed between rates of clinical remission at week 26 in patients with prior LOR (n = 48) and those with IFX intolerance (n = 21) (35% and 33%,
P
= 0.87, respectively). Thirty-two acute infusion reactions were recorded in 27 patients, leading to withdrawal of IFX in 20 patients. No pharmacokinetic characteristic at baseline but detection of positive anti-drug antibodies at week 4 was predictive of IFX failure or infusion reaction at week 26.
DISCUSSION:
In this first prospective cohort study, IFX retreatment was safe and effective in one-third of the patients with CD, regardless the reason of prior discontinuation. Early detection of anti-drug antibodies can predict subsequent IFX reintroduction failure and infusion reactions.
: Corticosteroids used to induce a response in Crohn's disease (CD) and ulcerative colitis (UC) may cause adverse reactions. The DICE study aimed to quantify and investigate factors associated with ...their use.
: This cross-sectional, non-interventional study conducted in seven countries allowed us to collect data on oral corticosteroid exposure and excessive use (cf. British Society of Gastroenterology) over the past 12 months in adult patients with CD or UC for more than a year. The factors associated with these practices were investigated using marginal logistic models. We present the results from the four participating French expert centers.
: Corticosteroid exposure over the past 12 months was observed in 20.1% of 324 CD patients and 30.2% of 205 UC patients. Excessive use was reported in 13.3% and 17.1% of patients, respectively. Corticosteroid exposure and excessive use were less frequently observed in CD than in UC (OR: 0.56,
< 0.0001, and 0.69,
= 0.0042). A disease activity assessment at patient's last visit was the main factor (
< 0.01) associated with the risk of corticosteroid exposure and excessive use in CD (OR: 3.41 and 3.44) and UC (OR: 7.29 and 6.90).
: Corticosteroid exposure and excessive use continue to be frequently observed in CD and UC in France.
Stricturing or penetrating lesions develop over time in most patients with Crohn's disease. The Lémann Index indicates the degree of digestive damage at a given time in an individual. We tracked ...changes in Lémann Index scores in an inception cohort of patients and looked for factors associated with digestive damage.
We studied 221 patients diagnosed with Crohn's disease from 2004 through 2011 who received 2 or 3 serial morphologic evaluations over a period of 2 to 10 years. We collected cross-sectional images and had them reviewed by a gastroenterologist and a radiologist; Lémann index scores were calculated. A value of 2 was chosen as the cut-off value for substantial transparietal damage. Factors associated with a score greater than 2 at the last evaluation and progression of index scores were identified using univariate analysis and logistic regression analyses.
The median index Lémann Index scores were 2.3 (interquartile range IQR, 1.2-3.9) at first evaluation, 3.5 (IQR, 1.2-8.6) at 2 to 5 years after diagnosis, and 8.3 (IQR, 1.2-12.1) at 5 to 10 years after diagnosis. Index scores increased significantly at each stage compared with initial or previous values (P < .0001). After 73 months (IQR, 51-96 mo) of follow-up evaluation, 138 patients had a Lémann Index score greater than 2.0. The only early factor that predicted later damage was the first index value. Intestinal resection, time, and the percentage of time elapsed with a clinically active disease were associated with progressing damage.
Based on an analysis of patients with Crohn's disease using the Lémann Index, nearly two thirds had substantial mucosal damage 2 to 10 years after diagnosis. High Lémann index scores at the first evaluation, time, persistent clinical activity, and intestinal resection are associated with damage.
Summary
Background
Genital fistulas represent a devastating complication of Crohn's disease. Only studies with small sample sizes have evaluated the efficacy of anti‐TNF therapy for this ...complication.
Aims
To assess the efficacy of anti‐TNF therapy for genital fistulas complicating Crohn's disease and to identify predictive factors associated with clinical response at 1 year.
Methods
Consecutive patients treated with anti‐TNF therapy for genital fistulas complicating Crohn's disease from 1999 to 2016 in 19 French centres from the Groupe d'Etude Thérapeutique des Affections Inflammatoires du tube Digestif were included in a retrospective cohort study. Outcome was clinical fistula closure at 1 year.
Results
Among the 204 women with genital fistulas who received anti‐TNF therapy, 131 were analysed. The first anti‐TNF given was infliximab (79%), adalimumab (20%), or certolizumab (1%). At start of anti‐TNF therapy, 56% of patients had seton drainage and 53% had concomitant immunosuppressive treatment. A complementary surgery was performed during the first year in 10 patients (8%). At 1 year, 37% of patients had complete clinical fistula closure, 22% had a partial response, and 41% had no response. Among patients without complementary surgery, 34% (41/121) had complete clinical fistula closure. Only complementary surgery was associated with better response on multivariate analysis (adjusted relative risk: 2.02, 95% CI: 1.25‐3.26, P = 0.0043).
Conclusions
In the anti‐TNF era, approximately one‐third of patients with genital fistula in Crohn's disease had complete fistula closure at 1 year. Collaboration between surgeons and gastroenterologists appears to be very important to improve the rate of fistula closure.
Proctocolectomy with ileal pouch-anal anastomosis is the intervention of choice for ulcerative colitis and familial adenomatous polyposis requiring surgery. One of the long-term complications is ...pouch cancer, having a poor prognosis. The risk of high-grade dysplasia and cancer in the anal transitional zone and ileal pouch after 20 years is estimated to be 2 to 4.5% and 3 to 10% in ulcerative colitis and familial polyposis, respectively. The risk factors for ulcerative colitis are the presence of pre-operative dysplasia or cancer, disease duration > 10 years and severe villous atrophy. For familial polyposis, the risk factors are the number of pre-operative polyps > 1000, surgery with stapled anastomosis and the duration of follow-up. In the case of ulcerative colitis, a pouchoscopy should be performed annually if one of the following is present: dysplasia and cancer at surgery, primary sclerosing cholangitis, villous atrophy and active pouchitis (every 5 years without any of these factors). In the case of familial polyposis, endoscopy is recommended every year including chromoendoscopy. Even if anal transitional zone and ileal pouch cancers seldom occur following proctectomy for ulcerative colitis and familial adenomatous polyposis, the high mortality rate associated with this complication warrants endoscopic monitoring.
Crohn's disease (CD) is associated with an increased risk of small bowel neoplasia (SBN). We aimed to assess preoperative predictors of SBN in CD patients. We conducted a retrospective case-control ...study including CD patients who underwent surgery: cases were diagnosed with SBN on histopathological analysis and controls had no neoplasia. Preoperative cross-sectional imaging was reviewed by a panel of blinded expert radiologists. Fifty cases were matched to one hundred and fifty consecutive controls. In multivariable analysis, predictors of SBN were age ≥ 50 years (OR = 28, 95% CI = 5.05-206), median CD duration ≥ 17.5 years (OR = 4.25, 95% CI = 1.33-14.3), and surgery for stricture (OR = 5.84, 95% CI = 1.27-35.4). The predictors of small bowel adenocarcinoma were age ≥ 50 years (OR = 5.14, 95% CI = 2.12-12.7), CD duration ≥ 15 years (OR = 5.65, 95% CI = 2.33-14.3), and digestive wall thickening > 8 mm (OR = 3.79, 95% CI = 1.45-11.3). A predictive score based on the aforementioned factors was constructed. Almost 73.7% of patients with a high score had SBA. Old age, long small bowel CD duration, and stricture predicted the presence of SBN, particularly adenocarcinoma when patients have digestive wall thickening > 8 mm on preoperative imaging.
Background: Several adalimumab preparations are now available for patients with inflammatory bowel disease (IBD). Comparative satisfaction and tolerability are unknown. Objectives: This study ...investigated IBD patient satisfaction with approved adalimumab biosimilars and their originator. Design: In this cross-sectional study, we included 941 consecutive adalimumab-treated patients with IBD across 45 centres affiliated with the Groupe d’Etude Therapeutique des Affections Inflammatoires du tube Digestif who completed a satisfaction questionnaire comprising four items each rated by a 10-point scale. Methods: The differences in responses were performed using a one-way analysis of variance followed by Tukey’s honest significant difference test. Results: The most commonly used drugs at inclusion were Humira ® (436/941, 46.3%), Amgevita ® (177/941, 18.8%) and Hulio ® (105/941, 11.2%). The mean overall satisfaction rate with adalimumab was 8.5 (standard deviation 1.8). Overall satisfaction was significantly higher in patients treated with Humira (8.6 (1.5)), Hulio (8.6 (1.8)) or Amgevita (8.5 (1.4)) ( p < 0.05). Satisfaction with the subcutaneous injection form was higher for patients treated with Yuflyma ® (9.0 (1.4)), Humira (8.9 (1.3)) and Hulio (8.9 (1.7)) ( p < 0.05). A total of 299 patients (31.8%) described injection site reactions. In all, 223 patients (23.7%) reported being previously treated with another adalimumab of which (32/223, 14.3%) discontinued treatment due to side effects. Conclusion: In this real-world setting, patients with IBD had a high level of satisfaction with adalimumab treatment, with some differences in terms of overall satisfaction and satisfaction with the injection device.
Association of vulvar Crohn’s disease (CD) with pyoderma gangrenosum (PG) has been described, yet due to its low prevalence, data on therapeutic management of this association are still limited. We ...here present a 22-year-old woman with severe vulvar and perianal CD with a major inguinal and perineal ulceration. In the hypothesis of an associated PG, oral corticosteroids were prescribed at a dose of 40 mg with limited efficacy for a duration of 3 months. Afterward, a combination treatment of cyclosporine and infliximab followed by negative pressure wound therapy and split-thickness skin graft resulted in complete healing.
