Background: The Lémann Index (LI) was recently developed to evaluate the cumulative bowel damage in patients with Crohn's disease (CD). Aims: To search for a difference between adalimumab and azathioprine to halt the progression of bowel damage in active CD, using the LI. Methods: A single-centre, retrospective study was conducted. Patients with CD were included if they had colonoscopy and magnetic resonance enterography performed within 4 months from the start of adalimumab or azathioprine and repeated after 12 months of therapy. Primary outcome was reached if the increase of LI after 12 months of treatment was <0.3, the drug was not stopped, and the use of systemic steroids was continued for no more than 3 months. Results: Ninety-one patients were enrolled, 31 (34.1%) of them treated with adalimumab and 60 (65.9%) with azathioprine. Sixty-seven percent of patients treated with adalimumab reached the primary outcome compared to 28.3% of patients treated with azathioprine ( p  = .0006). The LI in the group on adalimumab therapy decreased after 12 months (from 9.9 to 8.8), while in the group on azathioprine therapy it increased (from 7.7 to 8.8). Conclusion: Treatment with adalimumab halts the progression of bowel damage in CD while that with azathioprine does not.

Background: Occurring in approximately 20-30% of patients, spondyloarthritis is the most common extraintestinal manifestation in inflammatory bowel disease (IBD). Aims: To look for risk factors of spondyloarthritis among inflammatory bowel disease patients. Methods: We modified the STRIPP questionnaire created for psoriatic patients and we created a rapid questionnaire for rheumatologic investigation in IBD patients (STRII). We submitted the questionnaire to all consecutive patients with a known spondyloarthritis in our centre and to patients with a negative rheumatological diagnosis to find the cut-off value. Finally, we prospectively submitted the STRII questionnaire to all consecutive IBD patients in our centre. Results: A cut-off ≥3 correlated with spondyloarthritis with an AUC = 0.91. The STRII questionnaire was submitted to 1147 IBD patients. Two hundred and forty-four out of 1147 (21.3%) collected a STRII score of ≥3. Female sex ( p  < .0001) and Crohn's disease ( p  = .023) were risk factors. Patients with a history of at least 1 immunosuppressant or biologic drug ( p  = .002 and p  < .0001, respectively) had a higher rate of positivity to STRII questionnaire. Conclusion: Among IBD patients, females, Crohn's disease, those with a history of at least 1 immunosuppressive or biological therapy are at increased risk of spondyloarthritis.

Background: Inflammatory bowel diseases patients eligible for biological therapy represent a group with considerable disease burden and biologics only achieve 40% clinical remission rates in responders after 1 year of therapy. Aims: To collect all the published data about patients treated with dual biological therapy with an Anti-TNF, vedolizumab or ustekinumab, for a period of at least 3 months and to pool the data about the effectiveness and safety. Methods: A MEDLINE, and Web of Science search of all studies published in English until 1 January 2019 was conducted. Results: We included 7 studies with a total of 18 patients. Fifteen patients were treated with a combination of an anti-TNF and vedolizumab, 3 patients were treated with vedolizumab and ustekinumab. Fifty-six percent of patients were affected by Crohn's disease and 50% of patients were treated with an immunosuppressant drug or steroid too. A clinical improvement was obtained in 100% of patients, and an endoscopic improvement in 93% of patients. No serious adverse events were reported. Conclusions: The use of dual biological therapy is an attractive therapeutic option and may be an opportunity to better tailor and personalize the therapies for patients. Further studies, as randomized control trials, to provide comparative efficacy and safety endpoints of combination therapies, and to clarify potential advantages of combined biological therapies, are needed.

Objectives: In the setting of surveillance for hepatocellular carcinoma (HCC) detection, the use of serum biomarkers in addition to ultrasonography (US) is still a matter of debate. Hence, we performed a meta-analysis to evaluate the diagnostic accuracy of protein induced by vitamin K absence or antagonist-II (PIVKA-II) and alpha-fetoprotein (AFP) alone or in combination for HCC detection in patients at risk of tumor development., Materials and Methods: We performed a systematic search in PubMed and Scopus database for original articles published in English from 2011 to 2017, investigating the accuracy of PIVKA-II alone or in combination with AFP (reported as area under the curve [AUC]) for HCC detection among patients at risk of tumor development. Furthermore, we focused on studies in which serum PIVKA-II was assessed by highly sensitive chemiluminescence immunoassay (CLEIA)., Results: A total of 11 studies (873 patients with HCC and 1244 patients with advanced liver disease/cirrhosis) were included in the meta-analysis. The weighted summary AUC (sAUC) of PIVKA-II and AFP for the discrimination between patients with HCC and those without was 0.791 (0.746-0.837) and 0.767 (0.732-0.803), respectively. The combination of PIVKA-II + AFP results in a sAUC of 0.859 (0.837-0.882). The performance for HCC detection of PIVKA-II + AFP was significantly superior to each biomarker used alone (ΔsAUC = 0.068, p = .032 and ΔsAUC = 0.092, p < .001, respectively)., Conclusion: In clinical practice, the use of PIVKA-II + AFP in addition to US examination may improve the effectiveness of surveillance among patients at risk for HCC development.

Objectives: The therapy of the inflammatory bowel diseases is quite complex. A partial compliance increases the relapse probability and the health expenditure. The aim of the study is to correctly study the adherence to the therapy in a single centre eliminating the bias of a different relationship of trust with different doctors., Materials and Methods: We conducted a blind prospective study on the adherence evaluated for mesalazine., Results: Three hundred and seventy-six patients were included in the final analysis. Of the patients, 57.4% never missed a single dose of mesalazine, 29.3% missed one or two doses, 7.4% missed three to four doses, 5.9% missed more than five doses. A greater adherence among males (p = .015) and, in ulcerative colitis, among the group with a disease duration of <2 years compared to the one with a disease duration between 2 and 5 years (p = .04) were found. In Crohn's diseases, among the patients who had never undergone to surgical interventions, the adherence was 49.6%, compared to 51.9% among patients who underwent to one surgical resection and 78.6% among patients underwent to multiple surgical resections (p = .001)., Conclusions: The factors influencing the adherence to the therapy are only partly related to the prescribed therapy, but also to factors affecting the patient life: to increase the adherence rate it would be necessary not only interventions on the posology but also the psychological support to the patient at the time of the visit.
