Vedolizumab is a gut-selective anti-integrin (α4β7) antibody for the treatment of inflammatory bowel disease with a well-known optimal safety profile. We aimed to compare its risk of infections with that of anti-TNF drugs and ustekinumab in patients with both ulcerative colitis and Crohn's disease.All Crohn's disease and ulcerative colitis patients undergoing biological treatment at our centre between 2013 and 2019 were retrospectively included. All infectious complications were registered, considering both inpatient and outpatient events. A comparison of the exposure-adjusted infection rates of vedolizumab, anti-TNF drugs and ustekinumab was carried out, with a specific focus on the rate of gut infections. All infection rates were expressed in events per patient-years (PYs).The overall exposure-adjusted infection rate was 11.5/100 PYs. The most common infections were respiratory tract infections, cutaneous infections, HSV infections/reactivations and gut infections. The rate of serious infections was 1.3/100 PYs. The infection rate of vedolizumab was 17.5/100 PYs, with Crohn's disease patients having a lower infection risk compared with ulcerative colitis patients (P = 0.035). Gut infections were observed in 3.0% of the whole patient population (1.5/100 PYs) and were more common in the vedolizumab group (P = 0.0001).Our study confirms the good safety profile of vedolizumab. Among patients treated with vedolizumab, those with ulcerative colitis have a higher risk of developing infectious complications. Patients treated with vedolizumab have a higher risk of gut infections compared with patients treated with anti-TNF drugs or ustekinumab. Presumably, this is due to the gut-selective mechanism of action of vedolizumab.

Background Transjugular Intrahepatic Portosystemic Shunt (TIPS) is a well-established treatment for complications of portal hypertension. Aims To analyze the impact of TIPS on virologic response and safety profile in patients treated with direct-acting antivirals (DAAs). Methods We analyzed data from HCV-positive cirrhotic patients treated with DAAs. Twenty-one patients with previous TIPS placement were compared with 42 matched subjects without TIPS. Logistic regression was used to identify predictors of hepatic function worsening and adverse events. Results No differences were found between the two groups in particular regarding sustained virologic response (92.5 and 97.6% in TIPS vs no-TIPS, p = 0.559). Model for End-stage Liver Disease (MELD) of both TIPS and no-TIPS groups declined from baseline to week 24 of follow-up (from 12.5 ± 3.5 to 10.8 ± 3.4 and from 11.1 ± 3.5 to 10.3 ± 3.4, p = 0.044 and 0.025). There were no differences in adverse event rates. At univariate analysis, age was associated with MELD increase from baseline to week 24 (OR 1.111, 95% CI 1.019-1.211, p = 0.017), and patients with higher baseline MELD developed serious adverse events more frequently (OR 0.815, 95% CI 0.658–1.010, p = 0.062). Patients with or without TIPS did not show differences in transplant-free survival. Conclusion TIPS placement does not affect virologic response and clinical outcome of patients receiving DAAs.

The pandemic diffusion of the SARS-CoV-2 infection throughout the world required measures to prevent and strategies to control the infection, as well as the reallocation of the hospital structures in order to take care of an increased number of infected patients. Endoscopy Units should be able to perform endoscopic procedures on COVID-19 infected as well as on noninfected patients. The aim of this manuscript is to propose a model for a fast reorganization of the endoscopy department environment in order to safely perform endoscopic procedures in this Pandemic COVID-19 scenario, according to the current advices given by the Scientific Societies.

Stevens–Johnson syndrome (SJS) is a severe mucocutaneous adverse drug reaction with a relatively high mortality rate. SJS is described during herpes simplex virus type 1 (HSV1) infection and, rarely, even during adalimumab therapy. We report the case of a patient with Crohn’s disease who developed SJS during an HSV1 infection and a contemporaneous anti-TNFα therapy with adalimumab. Remission was achieved with suspension of adalimumab and high doses of intravenous steroids and antivirals. Patients with HSV1 infection and on adalimumab therapy have a combined risk of SJS and should be monitored closely.

Background Vedolizumab (VDZ) is a gut selective anti-α 4β 7 integrin antibody for the treatment of Inflammatory Bowel Disease with a well-known optimal safety profile. We aimed to compare the risk of infections of VDZ with that of anti-TNF drugs and ustekinumab, in patients with both ulcerative colitis (UC) and Crohn’s disease (CD). Methods All CD and UC patients undergoing biological treatment at our centre between June 2013 and June 2020 were retrospectively included. All infectious complications were registered, considering both inpatient and outpatient events. A comparison of exposure-adjusted infection rate of vedolizumab with that of anti-TNF drugs and ustekinumab was carried out, with a specific focus on the rate of gut infections. All infection rates were expressed in events per patient-years (PYs). Results The overall exposure-adjusted infection rate was 11.5/100 PYs. Detailed information about the infectious complications related to the different biologics is reported in Table 1. The most common infections were respiratory tract infections, cutaneous infections, HSV infections/reactivations, and gut infections. The rate of serious infections was 1.3/100 PYs. Among the 85 patients who were on a VDZ therapy, 17 (3 CD and 14 UC, median age 64, IQR 31–68) suffered an infectious complication. The exposure-adjusted incidence rate for vedolizumab was 17.5/100 PYs, with CD patients having a lower infection risk compared with UC patients (p = 0.035). Gut infections were observed in 3.0% of the whole patient population (1.5/100 PYs) and were more common in the VDZ group (p = 0.0001). Conclusion Our study confirms the good safety profile of vedolizumab. Among patients treated with vedolizumab, those with UC have a higher risk of developing infectious complications. Patients treated with vedolizumab have a higher risk of gut infections compared with patients treated with anti-TNF drugs or ustekinumab. Presumably, this could be due to the gut-selective mechanism of action of vedolizumab.
