Background: In the absence of head-to-head trials, there is an unmeet need to better understand the relative effectiveness of different biologics in inflammatory bowel disease (IBD). The Sicilian Network for Inflammatory Bowel Disease (SN-IBD) is a group composed by all Sicilian centres which continuously enter in a web-based software all clinical data of IBD patients treated with biologics. Methods: Data of all incident Crohn’s disease (CD) patients treated with infliximab (IFX) and adalimumab (ADA) from January 2013 to April 2017 were extracted from the cohort of SN-IBD. Patients were divided in biologic-naïve and non-naïve, and the two groups were analysed singularly. We used a one-to-two propensity score matching (1 IFX: 2 ADA) accounting for the main baseline characteristics in naïve patients, and a one-to-one propensity score matching (1 IFX: 1 ADA) in non-naïve. Results: Seven hundred and forty-seven naïve and 188 non-naïve patients were included. After propensity score matching, 453 naïve (IFX: 151; ADA: 302) and 100 non-naïve patients (total treatments: 122; IFX: 61; ADA: 61) were analysed. Among naïve patients, the rates of response/remission at 12 weeks for IFX and ADA were 80.1% and 81.1%,, respectively (adjusted OR 0.97, p = 0.923); over a median follow-up of 11.8 months, the rates of response/remission for IFX and ADA were 70.2% and 66.2%, respectively, without significant differences (adjusted OR 1.14, p = 0.401). Among non-naïve patients, the rates of response/remission at 12 weeks for IFX and ADA were 68.9% and 60.7%, respectively (adjusted OR 1.54, p = 0.320); over a median follow-up of 8.9 months, the rates of response/remission for IFX and ADA were 57.4% and 54.1%, respectively, without significant differences (adjusted OR 1.96, p = 0.297). Cox regression analysis showed no differences in risk of treatment failure between ADA and IFX, neither in naïve (adjusted HR 1.23, p = 0.381) nor in non-naïve patients (adjusted HR 1.23, p = 0.488). At multivariable conditional logistic regression analysis of naïve CD patients, upper GI involvement (OR 0.18, p = 0.038), previous surgery (OR 0.24, p = 0.003), and older age (OR 0.97, p = 0.036) were associated with lower clinical benefit at 12 weeks, while previous surgery was the only independent predictor of treatment failure at the end of follow-up (HR 2.13, p = 0.03). Mixed effect Cox analysis showed that non-naïve patients experiencing more than one previous line of treatment with biologics have a significant higher risk of treatment failure compared with those previously treated with one biologic only (HR 2.57, p = 0.002) Conclusions: In this large, propensity score matched, real-life, multicentre, cohort study of CD patients, there was no significant difference in the effectiveness of ADA and IFX. Both drugs showed a good efficacy.

Background: The monitoring of appropriateness, costs, and clinical outcomes of biological therapy in inflammatory bowel disease (IBD) is a relevant need. We aimed to evaluate all these issues in Sicily through a web based network of all prescribing centers. Methods: From January 2013, all IBD patients starting a biological agent (incident cases) or already on treatment (prevalent cases) were entered in a web based software. Herein we report data of incident cases about the efficacy of biological therapy after twelve weeks and one year of treatment. Results: From January 2013 to October 2016, 1475 patients were included. Incident cases were 1090. Considering that 16% of patients experienced more than one line of therapy, a total of 1351 treatments were reported. Adalimumab was used in 622 Crohn’s disease (CD) patients and in 83 ulcerative colitis (UC)/unclassified colitis patients. Infliximab was prescribed in 275 CD patients (80 biosimilars) and in 279 UC patients (50 biosimilars). Golimumab was used in 32 UC patients, while vedolizumab in 40 CD patients and in 20 UC patients. In patients with CD, after twelve weeks and one year of therapy, the rates of remission with adalimumab were 43.9% and 60.2%, respectively, and the rates of response 40.9% and 25.8%, while the rates of remission with infliximab originator were 46.2% and 50.0%, and the rates of response 40.9% and 32.9% (biosimilars: remission 31.0% and response 51.7% after 12 weeks; remission 45.5% and response 36.4% after one year). In UC, after twelve weeks and one year of therapy, the rates of remission with adalimumab were 43.3% and 57.1%, respectively, and the rates of response 36.7% and 19.0%; the rates of remission with infliximab originator were 41.6% and 48.4%, and the rates of response 35.6% and 32.3% (biosimilars: remission 30.0% and response 63.3% after 12 weeks; remission 20.0% and response 40.0% after one year); the rate of remission after 12 weeks of therapy with Golimumab was 22.2%, and the rate of response was 33.3%. After twelve weeks of therapy with Vedolizumab, 28.6% of CD patients were in remission and 32.0% had a response, while the rates of remission and response in UC patients were 33.3% and 22.0%, respectively. Multivariable logistic regression analysis showed that age >50 years was independently linked to lower rates of remission/response at 12 weeks in CD patients (OR 0.613, p=0.046). Conclusions: In one of the largest series of IBD patients on biological therapy reported to date, CD patients older than 50 years showed a higher rate of non response at 12 weeks of treatment. Efficacy of biosimilars was overall comparable to that reported for infliximab originator.

Background and aim: The monitoring of appropriateness and costs of biological therapy in Inflammatory bowel disease (IBD) is a relevant need. We aimed to evaluate appropriateness, efficacy and safety of biological therapy in IBD in Sicily through a web based network of prescribing centers. Material and methods: The Sicilian network for the monitoring of biological therapy in IBD is composed by a super Hub coordinator center and five Hub plus ten Spoke centers. From January 2013 all IBD patients starting a biological agent (incident cases) or already on treatment (prevalent cases) were entered in a web based software. Herein we report data on remission and response after twelve weeks of biological therapy, and side effects until the end of follow-up of incident cases. Results: From January 2013 to June 2016, 1475 patients were included. Complete data were available in 1338 cases (983 with Crohn’s disease [CD], 345 with ulcerative colitis [UC], and 10 with unclassified colitis). Incident cases were 956 (673 CD, 274 UC, and 9 unclassified colitis). Considering that 12% of patients experienced more than one line of therapy, a total of 1098 treatments were reported. Adalimumab was used in 543 CD patients, in 69 UC patients, and in 4 with unclassified colitis. Infliximab was prescribed in 221 CD patients (64 biosimilars), in 226 UC patients (41 biosimilars), and in 5 patients with unclassified colitis. Golimumab was prebscribed in 29 UC patients, and in 1 patient with unclassified colitis. After twelve weeks, the rate of response with Adalimumab was 46% and the rate of remission was 38% in CD, while the rate of response with Infliximab originator was 48% and the rate of remission 42% (biosimilars: 37% and 50%, respectively). In UC the rate of response with Adalimumab was 46% and the rate of remission was 38%, the rate of response with Infliximab was 41% and the rate of remission 45% (biosimilars: 25% and 64%, respectively), while the rate of response with Golimumab was 47% and the rate of remission was 27%. Overall, the rate of side effects was 17% (9.2% with Adalimumab, 20% with Infliximab originator, 15% with biosimilars, and 17% with Golimumab). Conclusions: In one of the largest series of IBD patients on biological therapy reported to date, the rates of remission and response after twelve weeks were comparable to data from literature, and similar between the different biologics. Efficacy and safety of biosimilars were analogous to those reported for infliximab originator.

As clinical end-point, we set remission (corresponding to a Mayo Partial Score 52 for UC, and to a Harvey-Bradshaw Index 55 for CD), and response (reduction of Harvey-Bradshaw Index

Duchenne muscular dystrophy (DMD) is characterized by progressive skeletal muscle weakness. We have previously shown that low-intensity endurance training prevented muscle damage (Frinchi et al, Int J Sports Med 2014). Since the effects of low-intensity endurance training on the the diaphragm in the mdx mouse model are unknown, in the same animals we investigated C x39 protein levels (Western blotting) in homogenates of the diaphragm before and after training. Mdx and wild-type (WT) mice were randomly assigned to sedentary (mdx-S, n=17; WT-S, n=19) or trained (mdx-EX, n=14; WT-EX, n=16) groups. Low-intensity endurance training (running on a wheel) was done 5 days/week for 6 weeks at progressively increasing time (15 min to 1 h) and speed (rpm from 16 to 24, distance covered during training sessions from 48 to 288 m). C ompared to our previous analysis of skeletal muscles changes in gastrocnemius and quadriceps, showing decreased muscle damage in trained vs sedentary mdx mice, analysis of protein level of C x39 showed similar values in diaphragm homogenates from sedentary and trained mdx mice.These preliminary data suggest that prevention of muscle necrosis after mild training does not occur in the diaphragm. As a speculation, continuous work of diaphragm vs intermittent work of skeletal muscle might at least partly account for the different results obtained in respiratory and locomotor muscle.
