BACKGROUND: Perianal fistulas of Crohn's disease (CD) create a significant burden on patients' lives. However, the efficacy and safety of adipose-derived mesenchymal stem cell treatment are contradicting, and real-world evidence is lacking. AIMS: To examine the usability of darvadstrocel therapy in managing perianal CD. METHODS: We enrolled patients with CD and perianal fistulas in this retrospective multicenter study. The primary outcome was perianal clinical remission (defined as all treated fistulas closed) at weeks 26 and 52. Secondary outcomes were clinical response rates (≥ 1 fistulas closed), perianal activity (PDAI), patient satisfaction, and adverse events. Data were recorded at baseline and weeks 12, 26 and 52. Prediction of primary outcomes was performed by logistic regression. RESULTS: Overall, among 223 patients (male/female ratio: 0.48), perianal clinical remission was achieved in 78.2% and 62.3% until weeks 26 and 52. Baseline PDAI score (OR 0.75), number of fistulas (OR 0.28) and the number of weeks after preparation for surgery (OR 0.98) were associated with treatment failure. The clinical response rates were 84.8% and 79.8% at weeks 26 and 52. Improvement of subjective perianal symptoms was achieved in 77.8% and 78.4% of patients, respectively. Adverse events occurred in 13.5% of patients; perianal abscesses and proctalgia were the most frequently reported. CONCLUSION: Effectiveness data were higher than in clinical trials. The safety profile was reassuring, and patients' satisfaction was high. Appropriate patient selection, fistula preparation and expertise may help to achieve treatment success.

BACKGROUND: STARDUST, a phase 3b randomised trial, compared ustekinumab therapeutic strategies in patients with Crohn's disease (CD) using early endoscopic assessment and treat-to-target (T2T) versus standard of care (SoC). AIM: To assess the efficacy of ustekinumab extended treatment in a long-term extension (LTE) of up to 104 weeks with dosing adapted according to clinical, biomarker and endoscopy outcomes. METHODS: Adults with moderately-to-severely active CD received intravenous ustekinumab approximating 6 mg/kg at Week 0 and subcutaneous ustekinumab 90 mg at Week 8. At Week 16, 440 ≥70-point responders were randomised to T2T or SoC and 323 entered the LTE. At Week 48, a unified, protocol-defined ustekinumab dose frequency escalation/de-escalation was applied based on achieving endoscopic remission and corticosteroid-free clinical remission. Achieving corticosteroid-free clinical remission and biomarker remission at consecutive visits determined ustekinumab dosing frequency. Dichotomous variables were analysed using non-responder imputation. RESULTS: Among patients who entered the LTE, 7.7%, 48.6% and 43.7% received doses every 4, 8 and 12 weeks, respectively. Ustekinumab dose frequency was escalated in 23.5% and de-escalated in 19.7%. Endoscopic response and remission rates were 28.9% and 10.73% (all randomised) and 39.3% and 14.6% (patients entering the LTE), respectively, at Week 104. Clinical remissiona rates at week 104 were 50.2% (all randomised) and 68.4% (patients entering the LTE). There were no new safety signals. CONCLUSION: STARDUST LTE is the first interventional ustekinumab efficacy study to show a favourable benefit-risk profile with preservation of clinical and endoscopic outcomes through Week 104 using flexible, algorithm-driven dose adjustment including de-escalation.

BACKGROUND: Risk benefit strategies in managing inflammatory bowel diseases (IBD) are dependent upon understanding the risks of uncontrolled inflammation vs those of treatments. Malignancy and mortality in IBD have been associated with disease-related inflammation and immune suppression, but data are limited due to their rare occurrence. AIM: To identify and describe the most common causes of mortality, types of cancer and previous or current therapy among children and young adults with paediatric-onset IBD. METHODS: Information on paediatric-onset IBD patients diagnosed with malignancy or mortality was prospectively collected via a survey in 25 countries over a 42-month period. Patients were included if death or malignancy occurred after IBD diagnosis but before the age of 26 years. RESULTS: In total, 60 patients were identified including 43 malignancies and 26 fatal cases (9 due to cancer). Main causes of fatality were malignancies (n = 9), IBD or IBD-therapy related nonmalignant causes (n = 10; including 5 infections), and suicides (n = 3). Three cases, all fatal, of hepatosplenic T-cell lymphoma were identified, all were biologic-naïve but thiopurine-exposed. No other haematological malignancies were fatal. The 6 other fatal cancer cases included 3 colorectal adenocarcinomas and 3 cholangiocarcinomas (CCAs). Primary sclerosing cholangitis (PSC) was present in 5 (56%) fatal cancers (1 colorectal carcinoma, 3 CCAs and 1 hepatosplenic T-cell lymphoma). CONCLUSIONS: We report the largest number of paediatric-onset IBD patients with cancer and/or fatal outcomes to date. Malignancies followed by infections were the major causes of mortality. We identified PSC as a significant risk factor for cancer-associated mortality. Disease-related adenocarcinomas were a commoner cause of death than lymphomas.

BACKGROUND: In 2013, a systematic review and Delphi consensus reported that specific probiotics can benefit adult patients with irritable bowel syndrome (IBS) and other gastrointestinal (GI) problems. AIM: To update the consensus with new evidence. METHODS: A systematic review identified randomised, placebo-controlled trials published between January 2012 and June 2017. Evidence was graded, previously developed statements were reassessed by an 8-expert panel, and agreement was reached via Delphi consensus. RESULTS: A total of 70 studies were included (IBS, 34; diarrhoea associated with antibiotics, 13; diarrhoea associated with Helicobacter pylori eradication therapy, 7; other conditions, 16). Of 15 studies that examined global IBS symptoms as a primary endpoint, 8 reported significant benefits of probiotics vs placebo. Consensus statements with 100% agreement and "high" evidence level indicated that specific probiotics help reduce overall symptom burden and abdominal pain in some patients with IBS and duration/intensity of diarrhoea in patients prescribed antibiotics or H. pylori eradication therapy, and have favourable safety. Statements with 70%-100% agreement and "moderate" evidence indicated that, in some patients with IBS, specific probiotics help reduce bloating/distension and improve bowel movement frequency/consistency. CONCLUSIONS: This updated review indicates that specific probiotics are beneficial in certain lower GI problems, although many of the new publications did not report benefits of probiotics, possibly due to inclusion of new, less efficacious preparations. Specific probiotics can relieve lower GI symptoms in IBS, prevent diarrhoea associated with antibiotics and H. pylori eradication therapy, and show favourable safety. This study will help clinicians recommend/prescribe probiotics for specific symptoms.

BACKGROUND: Previous studies have reached conflicting conclusions regarding the efficacy of mesalazine in the prevention of recurrent diverticulitis. AIM: To investigate the efficacy and safety of mesalazine granules in the prevention of recurrence of diverticulitis after acute uncomplicated diverticulitis. METHODS: Two phase 3, randomised, placebo-controlled, double-blind multicentre trials (SAG-37 and SAG-51) investigated mesalazine granules in patients with prior episodes (<6 months) of uncomplicated left-sided diverticulitis. Patients were randomised to receive either 3 g mesalazine once daily or placebo (SAG-37, n=345) or to receive either 1.5 g mesalazine once daily, 3 g once daily or placebo for 96 weeks (SAG-51, n=330). The primary endpoint was the proportion of recurrence-free patients during 48 weeks (SAG-37 and SAG-51) or 96 weeks (SAG-51) of treatment. RESULTS: Mesalazine did not increase the proportion of recurrence-free patients over 48 or 96 weeks compared to placebo. In SAG-37, the proportion of recurrence-free patients during 48 weeks was 67.9% with mesalazine and 74.4% with placebo (P=.226). In SAG-51, the proportion of recurrence-free patients over 48 weeks was 46.0% with 1.5 g mesalazine, 52.0% with 3 g mesalazine and 58.0% with placebo (P=.860 for 3 g mesalazine vs placebo) and over 96 weeks 6.9%, 9.8% and 23.1% respectively (P=.980 for 3 g mesalazine vs placebo). Patients with only one diverticulitis episode in the year prior to study entry had a lower recurrence risk compared to >1 episode. Safety data revealed no new adverse events. CONCLUSION: Mesalazine was not superior to placebo in preventing recurrence of diverticulitis.

BACKGROUND: A better knowledge of the natural history of disabling chronic diseases is essential to improve patient management, evaluate the impact of treatment strategies and provide predictors for disabling disease and comprehensive information for patients. AIM: To summarise our current knowledge issued from population-based studies of the natural history of ulcerative colitis (UC) in children. METHODS: We searched MEDLINE (source PubMed) and international conference abstracts, and included all population-based studies that evaluated long-term outcome of paediatric-onset (<17 years at diagnosis) UC. RESULTS: A total of 26 population-based studies were considered in this review from the total of 61 articles or abstracts screened. Most patients presented disease extension and about two-thirds of patients had pancolitis at the end of follow-up. One-half of patients experienced extra-intestinal manifestations and primary sclerosing cholangitis was observed in 5-10% of patients. Overall, patients did not appear to have any significant growth retardation or delayed puberty. About two-thirds of patients required corticosteroid therapy and up to 25% were steroid dependent. An increased use of thiopurines was observed and the most recent data indicate that up to one-half of patients were exposed to thiopurines and 10-30% were exposed to anti-tumour necrosis factor. One-half of patients required hospitalisations and 20% of patients required colectomy after a follow-up of 10 years. CONCLUSIONS: Paediatric-onset UC is characterised by a high rate of disease extension. About 20% of patients had been operated at 10-year follow-up. New population-based studies are needed to evaluate the impact of new treatment strategies comprising immunosuppressants and biologics.
BACKGROUND: Recently, infliximab dependency has been described. AIM: To assess frequency of ID in 82 consecutive Crohn's disease children treated with infliximab 2000-2006 and to describe clinical and genetic predictors of long-term infliximab response. METHODS: A phenotype model of infliximab dependency was used to assess treatment response: 'immediate outcome' (30 days after infliximab start)--complete/partial/no response. 'Long-term outcome': (i) prolonged response: maintenance of complete/partial response; (ii) infliximab dependency: relapse < or = 90 days after intended infliximab cessation requiring repeated infusions to regain complete/partial response or need of infliximab >12 months to sustain response. Polymorphisms TNF-308 A>G, TNF-857 C>T, Casp9 93 C>T, FasL-844 C>T, LTA 252 C>T and CARD15 (R702W, G908R, 1007fs) were analysed. RESULTS: Ninety-four per cent of children obtained complete/partial response. In long-term outcome, 22% maintained prolonged response, 12% had no response, while 66% became infliximab dependent. Perianal disease and no previous surgery were associated with infliximab dependency (OR 5.34, 95% CI: 1.24-22.55; OR 6.7, 95% CI: 1.67-26.61). No association was found with studied polymorphisms. The cumulative probability of surgery 50 months after starting infliximab was 10% in infliximab dependency, 30% in prolonged responders and 70% in nonresponders (P = 0.0002). CONCLUSIONS: Sixty-six per cent of children became infliximab dependent. Perianal disease and no surgery prior to infliximab were associated with infliximab dependency phenotype.
