Signatures of disease outcome severity in the intestinal fungal and bacterial microbiome of COVID-19 patients.

Background: COVID-19, whose causative pathogen is the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), was declared a pandemic in March 2020. The gastrointestinal tract is one of the targets of this virus, and mounting evidence suggests that gastrointestinal symptoms may contribute to disease severity. The gut-lung axis is involved in the immune response to SARS-CoV-2; therefore, we investigated whether COVID-19 patients' bacterial and fungal gut microbiome composition was linked to disease clinical outcome.

Effectiveness of swapping to ustekinumab after vedolizumab failure in patients with multi-refractory Crohn's disease.

Background: Ustekinumab (UST) and vedolizumab (VDZ) are biologic therapies for moderate-to-severe Crohn's disease (CD) in patients who failed or had contraindication to anti-TNF treatment.

Aims: To evaluate ustekinumab efficacy as third-line treatment after swapping from VDZ for failure.

Methods: We conducted a monocentric, retrospective, observational study where CD patients were followed for 12 months from the beginning of UST therapy.

COVID-19 in IBD: The experience of a single tertiary IBD center.

Background: Italy has been one of the most affected countries in the world by COVID-19. There has been increasing concern regarding the impact of COVID-19 on patients with inflammatory bowel disease (IBD), particularly in patients treated with immunosuppressants or biologics. The aim of our study is to understand the incidence of COVID-19 in a large cohort of patients with IBD.

Performance of Capsule Endoscopy and Cross-Sectional Techniques in Detecting Small Bowel Lesions in Patients with Crohn's Disease.

Background: Crohn's disease (CD) can be classified according to endoscopic and cross-sectional imaging characteristics. Information regarding disease extent and phenotype may be provided by advanced endoscopic and imaging techniques. In this study, we compare the ability of capsule endoscopy (CE) and cross-sectional imaging techniques (CST) (MRE/Computer Tomography Enteroscopy [CTE]) in detecting small bowel (SB) lesions.

Usefulness of panoramic 344°-viewing in Crohn's disease capsule endoscopy: a proof of concept pilot study with the novel PillCam™ Crohn's system.

Background: A new capsule endoscopy (CE) system featuring two advanced optics for 344°-viewing and a prolonged operative time has been recently developed for Crohn's disease (CD) patients. Hence, we evaluated, for the first time, the performance of this novel CE and the add-on value of the 344°-viewing in a multi-center real-life setting.

Methods: Consecutive patients with suspected or established CD received the PillCam™ Crohn's System as supplementary diagnostic work-up focused on the small-bowel between June 2017 and June 2018.

Ultrasonographic and clinical assessment of peripheral enthesitis and arthritis in an Italian cohort of inflammatory bowel disease patients.

Aims: To evaluate the prevalence of clinical and ultrasonographic musculoskeletal involvement in Italian patients with inflammatory bowel disease (IBD).

Methods: In this cross-sectional multicenter study, 148 consecutive patients with IBD were evaluated by a gastroenterologist and a rheumatologist. All patients underwent a B-mode and power Doppler ultrasonographic examination of 6 pairs of entheses and of knee and ankle joints.

Budesonide MMX: efficacy and safety profile in the treatment of ulcerative colitis.

: Ulcerative colitis is an idiopathic, chronic inflammatory disease of the colonic mucosa. Its clinical course is unpredictable, marked by alternating periods of exacerbation and remission. Traditional oral corticosteroids are still the mainstay treatment for the induction of ulcerative colitis remission in patients failing or intolerant to aminosalicylates, but the risk of side effects and complications limits their usefulness.

Implications of the Westernized Diet in the Onset and Progression of IBD.

Inflammatory bowel diseases (IBD) are currently considered multifactorial pathologies in which various combined environmental factors act on a genetic background, giving rise to a chronic inflammation of the gastrointestinal tract. Among the various environmental factors, it now seems clear that the diet plays the major role in IBD onset and progression. Several clinical studies have attempted to understand the impact of diet in the development and progression of these diseases in order to establish useful guidelines for their management.

A current overview of corticosteroid use in active ulcerative colitis.

Ulcerative colitis (UC) is a chronic inflammatory condition that causes continuous mucosal inflammation of the colon. New biological drugs have been developed in order to avoid colectomy, but corticosteroids still play a crucial role in management of active UC. Areas covered: We reviewed the current literature about the importance of corticosteroid use in the treatment of ulcerative colitis.

The safety of beclomethasone dipropionate in the treatment of ulcerative colitis.

Beclomethasone dipropionate (BDP) is a second-generation corticosteroid that uses novel drug technologies to ensure colonic targeting and potentially reducing systemic corticosteroid concentrations. It is approved for treatment of patients with mild-to-moderate ulcerative colitis (UC) who do not respond to mesalazine. The gut-selective mechanism of action has the potential to improve the safety profile of BDP compared with other conventional corticosteroids.
