RESUMEN
BACKGROUND: Microbial imbalance is thought to play a role in the pathogenesis of Diverticular Disease (DD). OBJECTIVE: We aimed to assess the efficacy of a symbiotic mixture (Prolactis GG Plus®) in the treatment of moderate to severe DD, scored according to the Diverticular Inflammation and Complication Assessment (DICA) classification. METHODS: A retrospective study was conducted enrolling the following patients: at the first diagnosis of DD; in whom DD was diagnosed with colonoscopy and scored according to DICA classification; treated with Prolactis GG Plus® two times/daily for 2 consecutive months; in whom the severity of the abdominal pain was scored with a 10-points visual-analogue scale (VAS) at baseline and the end of follow-up; in whom fecal calprotectin (FC) was assessed at baseline and the end of follow-up as µg/g. RESULTS: Twenty-four patients were identified (10 males, 14 females; 16 as DICA 2, and 8 as DICA 3). Prolactis GG Plus® decreased the severity of abdominal pain both in DICA 2 (p =0.02) and DICA 3 patients (p =0.01), while FC decreased significantly in DICA 2 (p <0.02) but not in DICA 3 (p =0.123) patients. Acute diverticulitis occurred during the follow-up in two DICA 3 patients but none DICA 2 patients. Add-on therapy was required by eight DICA 2 (50%) and six DICA 3 patients (75%). CONCLUSION: In newly diagnosed patients with DD, the symbiotic mixture Prolactis GG Plus® can be a potential treatment for moderate (DICA 2) DD as a single treatment.
RESUMEN
Inflammatory bowel diseases, comprising Crohn's disease (CD) and ulcerative colitis (UC), are chronic, relapsing, and remitting immune-mediated inflammatory diseases affecting the gastrointestinal tract. Ustekinumab (UST) is a monoclonal antibody that blocks the p40 subunit of the anti-interleukin (IL) 12/23. Pivotal trials (CERTIFI and UNITI-IM for CD, UNIFI for UC) established the efficacy of UST for the induction and maintenance of remission in both CD and UC, with the most favorable results in naïve patients to biologics. In recent years, a wealth of 'real-world' data has emerged supporting positive clinical, endoscopic, and histological outcomes in patients treated with UST, as well as reassuring safety data. More recently, the results of the first head-to-head trials of UST and tumor necrosis factor (TNF) antagonists were reported. Moreover, a number of studies exploring the role of UST in specific clinical settings, such as perianal CD, postoperative complications and recurrence, extraintestinal manifestations, chronic antibiotic-refractory pouchitis, and pregnancy, were reported. This review explores the results reported to date on UST, including those from pivotal trials, real-world data, and emerging studies regarding therapeutic drug monitoring and immunogenicity. The safety profile of UST was also reviewed.
RESUMEN
INTRODUCTION: The therapeutic armamentarium for managing Crohn's disease (CD) has expanded significantly in recent decades. Several biologics with three different mechanisms of action [anti-tumor necrosis factor (TNF)-α, anti-integrin α4ß7, and anti-IL 12/23] are currently available to manage CD. AREA COVERED: This narrative review aims to summarize the most significant efficacy and safety data on the use of infliximab (IFX), adalimumab (ADA), vedolizumab (VDZ) and ustekinumab (UST) for the treatment of CD obtained from studies conducted in the real world (RW), compared to the results of randomized clinical trials (RCTs). EXPERT OPINION: RW studies reported that biologic agents included in this analysis have higher remission rates and lower adverse event rates than findings from RCTs for treating patients with CD. All biological agents have proven effective and safe in RW studies, even when using biosimilars or switching to subcutaneous administration of the molecules for which they are available. Finally, anti-TNF-α agents, particularly IFX, have a higher rate of adverse events (AEs) than VDZ and UST. Therefore, patients at higher risk of AEs may benefit from other biologics than anti-TNF-α. However, further long-term RW studies are needed to confirm these findings.

BACKGROUND: Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist recently approved for treating ulcerative colitis (UC) but with limited real-world data. Therefore, we evaluated the effectiveness and safety of UST in patients with UC in a real-world setting. RESEARCH DESIGN AND METHODS: This is a multicenter, retrospective, observational cohort study. The primary endpoints were the clinical remission rate (partial Mayo score, PMS, ≤1) and the safety of UST. Other endpoints were corticosteroid-free remission (CSFR) rate, clinical response rate (PMS reduction of at least 2 points), and fecal calprotectin (FC) reduction at week 24. RESULTS: We included 256 consecutive patients with UC (M/F 139/117, median age 52). The clinical remission and clinical response rates at eight weeks were 18.7% (44/235) and 53.2% (125/235), respectively, and 27.6% (42/152) and 61.8% (94/152) at 24 weeks, respectively. At 24 weeks, CSFR was 20.3% (31/152), and FC significantly dropped at week 12 (p = 0.0004) and 24 (p = 0.038). At eight weeks, patients naïve or with one previous biologic treatment showed higher remission (p = 0.002) and clinical >response rates (p = 0.018) than patients previously treated with ≥ 2. Adverse events occurred in six patients (2.3%), whereas four patients (1.6%) underwent colectomy. CONCLUSION: This real-world study shows that UST effectively and safely treats patients with UC.
