Methotrexate Is Not Superior to Placebo for Inducing Steroid-Free Remission, but Induces Steroid-Free Clinical Remission in a Larger Proportion of Patients With Ulcerative Colitis
La voix pop
Au coeur de la pop, au coeur des chansons de toutes sortes, il y a la voix. Si souvent, elle nous touche, elle nous marque : nous ne l'oublions plus, nous pouvons parfois la reconnaître en une inflexion, en une fraction de seconde, avant même la fin de la première note. D'autres fois, elle nous est encore inconnue, nous la découvrons, et pourtant nous sommes en mesure de l'apprécier. Alors même que depuis des décennies on sait la capter, l'enregistrer, la restituer, la transformer, la voix pop n'a suscité que récemment l'intérêt de la recherche. C'est le défi que relève ce numéro double, qui explore au travers d'études de cas variées (black metal, rap, chanson française, rock...) de nouvelles méthodes analytiques pour caractériser la voix pop dans ses singularités. At the heart of all sorts of pop tunes, there is voice. We are often touched and marked by it: we never forget it, we can sometimes recognize it in little more than an inflection, in a split second, before the first note has vanished. In other moments, it remains unknown to us, we discover it, and yet we are able to appreciate it. Although for decades we have known how to pick it up, how to record, reproduce and transform it, the pop voice has only recently been analyzed by scientific studies. This issue explore its singularities, through a variety of case studies (black metal, rap, French chanson, rock music…) and with new analytical methods
Methotrexate Is Not Superior to Placebo for Inducing Steroid-Free Remission, but Induces Steroid-Free Clinical Remission in a Larger Proportion of Patients With Ulcerative Colitis.
BACKGROUND & AIMS: Parenteral methotrexate is an effective treatment for patients with Crohn's disease, but has never been adequately evaluated in patients with ulcerative colitis (UC). We conducted a randomized controlled trial to determine its safety and efficacy in patients with steroid-dependent UC.
METHODS: We performed a double-blind, placebo-controlled trial to evaluate the efficacy of parenteral methotrexate (25 mg/wk) in 111 patients with corticosteroid-dependent UC at 26 medical centers in Europe from 2007 through 2013. Patients were given prednisone (10 to 40 mg/d) when the study began and were randomly assigned to groups (1:1) given placebo or methotrexate (intramuscularly or subcutaneously, 25 mg weekly) for 24 weeks. The primary end point was steroid-free remission (defined as a Mayo score ≤2 with no item >1 and complete withdrawal of steroids) at week 16. Secondary endpoints included clinical remission (defined as a Mayo clinical subscore ≤2 with no item >1) and endoscopic healing without steroids at weeks 16 and/or 24, remission without steroids at week 24, and remission at both weeks 16 and 24.
RESULTS: Steroid-free remission at week 16 was achieved by 19 of 60 patients given methotrexate (31.7%) and 10 of 51 patients given placebo (19.6%)--a difference of 12.1% (95% confidence interval [CI]: -4.0% to 28.1%; P = .15). The proportion of patients in steroid-free clinical remission at week 16 was 41.7% in the methotrexate group and 23.5% in the placebo group, for a difference of 18.1% (95% CI: 1.1% to 35.2%; P = .04). The proportions of patients with steroid-free endoscopic healing at week 16 were 35% in the methotrexate group and 25.5% in the placebo group--a difference of 9.5% (95% CI: -7.5% to 26.5%; P = .28). No differences were observed in other secondary end points. More patients receiving placebo discontinued the study because of adverse events (47.1%), mostly caused by UC, than patients receiving methotrexate (26.7%; P = .03). A higher proportion of patients in the methotrexate group had nausea and vomiting (21.7%) than in the placebo group (3.9%; P = .006).
CONCLUSIONS: In a randomized controlled trial, parenteral methotrexate was not superior to placebo for induction of steroid-free remission in patients with UC. However, methotrexate induced clinical remission without steroids in a significantly larger percentage of patients, resulting in fewer withdrawals from therapy due to active UC.

Excess risk of urinary tract cancers in patients receiving thiopurines for inflammatory bowel disease: a prospective observational cohort study
IF 6.32International audienceBackgroundThe risk of urinary tract cancers, including kidney and bladder cancers, was increased in transplant recipients receiving thiopurines.AimTo assess the risk of urinary tract cancers in patients with inflammatory bowel disease (IBD) receiving thiopurines in the CESAME observational cohort.MethodsBetween May 2004 and June 2005, 19 486 patients with IBD, 30.1% of whom were receiving thiopurines, were enrolled. Median follow‐up was 35 months (IQR: 29–40).ResultsTen and six patients developed respectively kidney and bladder cancer. The incidence rates of urinary tract cancer were 0.48/1000 patient‐years in patients receiving thiopurines (95% CI: 0.21–0.95), 0.10/1000 patient‐years in patients who discontinued thiopurines (95% CI: 0.00–0.56) and 0.30/1000 patient‐years in patients never treated with thiopurines (95% CI: 0.12–0.62) at entry. The standardised incidence ratio of urinary tract cancer was 3.40 (95% CI: 1.47–6.71, P = 0.006) in patients receiving thiopurines, 0.64 (95% CI: 0.01–3.56, P = 0.92) in patients previously exposed to thiopurines and 1.17 (95% CI: 0.47–12.42, P = 0.78) in patients never treated with thiopurines. The multivariate‐adjusted hazard ratio (HR) of urinary tract cancer between patients receiving thiopurines and those not receiving thiopurines was 2.82 (95% CI: 1.04–7.68, P = 0.04). Other significant risk factors were male gender (HR: 3.98, 95% CI: 1.12–14.10, P = 0.03) and increasing age (HR after 65 years (ref <50): 13.26, 95% CI: 3.52–50.03, P = 0.0001).ConclusionPatients with IBD receiving thiopurines have an increased risk of urinary tract cancers. Clinically relevant excess risk is observed in older men
