Muscari comosum L. Bulb Extracts Modulate Oxidative Stress and Redox Signaling in HepG2 Cells.

Muscari comosum L. bulbs are commonly used as food in South Italy and also in folk medicine. By evaluating in vitro antioxidant activity and biological activities of their aqueous and methanol extracts, we shed light on the potential role, including both the nutraceutical and health benefits, of this plant. Total polyphenol content (TPC) and total flavonoid content (TFC) were evaluated by the Folin-Ciocalteu method and by the aluminum chloride method, respectively. Antioxidant activity was investigated by three in vitro assays and relative antioxidant capacity index (RACI) was calculated to compare results obtained by different tests. The extracts were tested to evaluate their possible involvement in redox homeostasis, using the human hepatoma (HepG2) cell line used as model. The extracts exhibited concentration/solvent dependent radical scavenging activity, as well as dysregulation of some genes involved in redox pathways by promoting Nrf2, SOD-2, GPX1, ABCC6 and ABCG2 expression. NMR metabolomics analysis suggests that HepG2 cells treated with Muscari comosum extracts experience changes in some metabolites involved in various metabolic pathways

Timing of proper introduction, optimization and maintenance of anti-TNF therapy in IBD: Results from a Delphi consensus

Background: Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBDs) with a rapidly growing worldwide incidence. The last decades presented rapid progress in pharmacological treatment leading in many cases to clinical and endoscopic remission, including biological treatment with anti-TNF agents. Aim: The exact timing of introduction, optimization and maintenance of anti-TNF therapy in IBDs is not thoroughly covered in current guidelines. Methods: We used the Delphi panel methodology to gather the IBD experts' views and achieve consensus for clinical recommendations on introducing and maintaining anti-TNF therapy for patients with IBDs. Results: Twelve recommendations achieved a high level of consensus in two assessment rounds by 52 (1st round) and 47 (2nd round) IBD experts. Conclusion: In many clinical situations, the early use of anti-TNF therapy is recommended. Nowadays, the cost-efficacy profile of anti-TNF biosimilars makes them the first-line drug in a substantial proportion of patients, thus providing the opportunity to increase access to biological therapy

Psoriasis Features in Patients with Inflammatory Bowel Disease

BACKGROUND: Psoriasis and inflammatory bowel diseases (IBD) share common pathways based on immune dysregulation with an important role of tumour necrosis factor-α and Th17 cells, as well as the genetic background. Several studies showed an increased prevalence of psoriasis in IBD patients. However, data regarding psoriasis features in IBD patients are still lacking. AIM: We aimed to conduct an observational study to assess psoriasis clinical features and its severity in a group of patients with IBD. METHODS: Dermatological assessment was performed consecutively in 200 IBD patients (123 with CD and 77 with UC) attending the IBD Care Centre of Gastroenterology at the University of Naples Federico II from 2015 to 2016. RESULTS: A group of 32 from 200 IBD patients (16%) had a familiar history positive for psoriasis, whereas, medical history and dermatologic examination revealed that 18 (9%) IBD patients were affected by psoriasis: 11 out of these 18 subjects (61.2%) had CD, and 7 had UC (38.2%); no significant differences were found between CD and UC groups. Concerning psoriasis severity, the mean psoriasis area severity index score was 3.7. CONCLUSION: This one-year retrospective study showed that psoriasis and IBD both require the use of immunosuppressive drugs so; we can count on a better treatment outcome for both diseases

Comparison of two strategies for the management of postoperative recurrence in Crohn's disease patients with one clinical risk factor: A multicentre IG-IBD study

BackgroundThe management of postoperative recurrence (POR) in Crohn's disease (CD) after ileo-colonic resection is a highly debated topic. Prophylactic immunosuppression after surgery is currently recommended in the presence of at least one clinical risk factor. ObjectiveOur aim was to determine whether early immunosuppression can be avoided and guided by endoscopy in CD patients with only one risk factor. MethodsCD patients with only one risk factor for POR, including previous intestinal resection, extensive small intestine resection (>50 cm), fistulising phenotype, history of perianal disease, and active smoking, were retrospectively included. Two groups were formed based on whether immunosuppression was started immediately after surgery ("prophylaxis group") or guided by endoscopy ("endoscopy-driven group"). Primary endpoints were rates of any endoscopic recurrence (Rutgeerts >= i2a) and severe endoscopic recurrence (i4) within 12 months after surgery. Secondary outcomes were clinical recurrence rates at 6, 12 and 24 months after surgery. ResultsA total of 195 patients were enroled, of whom 61 (31.3%) received immunoprophylaxis. No differences between immunoprophylaxis and the endoscopy-driven approach were found regarding any endoscopic recurrence (36.1% vs. 45.5%, respectively, p = 0.10) and severe endoscopic recurrence (9.8% vs. 15.7%, respectively, p = 0.15) at the first endoscopic evaluation. Clinical recurrence rates were also not statistically different (p = 0.43, p = 0.09, and p = 0.63 at 6, 12, and 24 months, respectively). ConclusionsIn operated CD patients with only one risk factor for POR, immediate immunoprophylaxis does not decrease the rate of early clinical and endoscopic recurrence. Prospective studies are needed to confirm our results

Reduced humoral response to two doses of COVID-19 vaccine in patients with inflammatory bowel disease: Data from ESCAPE-IBD, an IG-IBD study

Background Patients on immunosuppressive drugs have been excluded from COVID-19 vaccines trials, creating concerns regarding their efficacy. Aims To explore the humoral response to COVID-19 vaccines in patients with inflammatory bowel disease (IBD) Methods Effectiveness and Safety of COVID-19 Vaccine in Patients with Inflammatory Bowel Disease (IBD) Treated with Immunomodulatory or Biological Drugs (ESCAPE-IBD) is a prospective, multicentre study promoted by the Italian Group for the study of Inflammatory Bowel Disease. We present data on serological response eight weeks after the second dose of COVID-19 vaccination in IBD patients and healthy controls (HCs). Results 1076 patients with IBD and 1126 HCs were analyzed. Seropositivity for anti-SARS-CoV-2 IgG was reported for most IBD patients, even if with a lesser rate compared with HCs (92.1% vs. 97.9%; p<0.001). HCs had higher antibody concentrations (median OD 8.72 [IQR 5.2-14-2]) compared to the whole cohort of IBD patients (median OD 1.54 [IQR 0.8-3.6]; p<0.001) and the subgroup of IBD patients (n=280) without any treatment or on aminosalicylates only (median OD 1.72 [IQR 1.0–4.1]; p<0.001). Conclusions Although most IBD patients showed seropositivity after COVID-19 vaccines, the magnitude of the humoral response was significantly lower than in HCs. Differently from other studies, these findings seem to be mostly unrelated to the use of immune-modifying treatments (ClinicalTrials.govID:NCT04769258)

Effectiveness and safety of vedolizumab in a matched cohort of elderly and nonelderly patients with inflammatory bowel disease: the IG-IBD LIVE study

Background Vedolizumab registration trials were the first to include elderly patients with moderate-to-severe ulcerative colitis (UC) or Crohn's disease (CD), but few real-life data have been reported in this population. Aims We investigated the effectiveness and safety of vedolizumab in matched cohorts of elderly and nonelderly UC and CD patients. Methods The Long-term Italian Vedolizumab Effectiveness (LIVE) study is a retrospective-prospective study including UC and CD patients who started vedolizumab from April 2016 to June 2017. Elderly patients (>= 65 years) were matched clinically 1:2 to nonelderly patients (18-64 years); the 2 groups were followed until drug discontinuation or June 2019. Results The study included 198 elderly (108 UC, 90 CD) and 396 matched nonelderly patients (205 UC, 191 CD). Nonelderly UC patients had a significantly higher persistence on vedolizumab compared to elderly patients (67.6% vs. 51.4%, p = 0.02). No significant difference in effectiveness was observed between elderly and nonelderly CD patients (59.4% vs. 52.4%, p = 0.32). Age >= 65 years was associated with lower persistence in UC; for CD, previous exposure to anti-TNF-alpha agents, Charlson comorbidity index >2 and moderate-to-severe clinical activity at baseline were associated with lower persistence. There were recorded 130 adverse events, with comparable rates between the two groups. A Charlson comorbidity index >2 was associated with an increased risk of adverse events. Conclusion Vedolizumab can be considered a safe option in elderly IBD patients. Its effectiveness in elderly UC patients may be reduced, while no age-dependent effect on effectiveness was observed in CD
