Impact of SARS-CoV-2 Pandemic on Vascular Liver Diseases.

BACKGROUND & AIMS: Vascular liver diseases (VLDs) are represented mainly by portosinusoidal vascular disease (PSVD), noncirrhotic splanchnic vein thrombosis (SVT), and Budd Chiari syndrome (BCS). It is unknown whether patients with VLDs constitute a high-risk population for complications and greater coronavirus disease 2019 (COVID-19)-related mortality from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Our objective was to assess the prevalence and severity of SARS-CoV-2 infection among patients with VLDs, as well as to assess its impact on hepatic decompensation and survival. METHODS: This is an observational international study analyzing the prevalence and severity of SARS-CoV-2 infection in VLDs between March 2020 and March 2021, compared with the general population (GP). Patients from Spain (5 centers; n = 493) and France (1 center; n = 475) were included. RESULTS: Nine hundred sixty-eight patients were included: 274 with PSVD, 539 with SVT, and 155 with BCS. Among them, 138 (14%) were infected with SARS-CoV-2: 53 with PSVD, 77 with SVT, and 8 with BCS. The prevalence of SARS-CoV-2 infection in patients with PSVD (19%) and SVT (14%) was significantly higher than in the GP (6.5%; P < .05), whereas it was very similar in patients with BCS (5%). In terms of infection severity, patients with VLDs also presented a higher need of hospital admission (14% vs 7.3%; P < .01), intensive care unit admission (2% vs 0.7%; P < .01), and mortality (4% vs 1.5%; P < .05) than the GP. Previous history of ascites (50% vs 8%; P < .05) and post-COVID-19 hepatic decompensation (50% vs 4%; P < .05) were associated with COVID-19 mortality. CONCLUSIONS: Patients with PSVD and SVT could be at higher risk of infection by SARS-CoV-2 and at higher risk of severe COVID-19 disease.

Risk of Late Postoperative Recurrence of Crohn's Disease in Patients in Endoscopic Remission After Ileocecal Resection, Over 10 Years at Multiple Centers.

BACKGROUND & AIMS: The risk of recurrence of Crohn's disease (CD) from 1 to 10 years after surgery despite initial endoscopic remission (late post-operative recurrence) is not clear. METHODS: We performed a retrospective study, at 3 inflammatory bowel disease (IBD) centers in France and Belgium, of all patients with CD (n = 86) undergoing an ileocecal resection with curative intent from 2006 through 2016 who did not have endoscopic evidence for recurrence (Rutgeerts score less than i2) at their baseline assessment. Postoperative recurrence after baseline endoscopy was defined as a composite endpoint of at least 1 of the following: clinical recurrence, IBD-related hospitalization, occurrence of bowel damage, need for endoscopic balloon dilatation of the anastomosis, and need to repeat the surgery. Risk of mucosal disease progression was studied as a secondary outcome. RESULTS: The median time between surgery and baseline endoscopy was 7 months (IQR, 5.7-9.5 months); 40 patients (46.5%) received medical prophylaxis in this period. The median follow-up time was 3.5 years (IQR, 1.6-5.3 years). Thirty-five patients (40.7%) had a late post-operative recurrence of CD, with a median time to disease recurrence after baseline endoscopy of 14.2 months (IQR, 6.3-26.1 months). Recurrence status did not differ significantly between patients with Rutgeerts scores of i0 (20/55) or i1 (15/31) at baseline (P = .28) and was independent of medical prophylaxis (16/40 with prophylactic therapy vs 19/46 without prophylactic therapy; P = .90). Mucosal disease progressed in 29 of the 71 patients (40.8%) with available data. We did not identify risk factors for late post-operative recurrence of CD or mucosal disease progression. CONCLUSIONS: Among patients with CD treated by ileocecal resection, 40% of patients had a late recurrence, despite initial endoscopic remission, after a median follow-up time of 3.5 years. Tight monitoring of these patients is recommended beyond 18 months.

Early Post-Operative Endoscopy Is Associated with Lower Surgical Recurrence of Crohn's Disease: A Retrospective Study of Three Successive Cohorts.

Background: The severity of endoscopic recurrence during the first year after intestinal resection for Crohn's disease is predictive of clinical recurrence. The aim of our study was to assess the impact of the implementation of an ileocolonoscopy during the first year after surgery on surgical recurrence. Methods: All patients who underwent a first intestinal resection for Crohn's disease between 1992 and 2018 at the University Hospital of Liège were retrospectively included. The time to surgical recurrence was compared in three successive groups of patients operated on in the period 1992-2001 (group A), 2002-2011 (group B), and 2012-2020 (group C) using the Kaplan-Meier method and the Log-Rank test. To identify independent prognostic factors, a multivariate analysis was used via the Cox model. Results: 223 patients (group A = 69, group B = 94, group C = 60) were included. Probabilities of surgical recurrence were significantly lower in group C (2.2% and 4.7% at 3 and 5 years, respectively) compared with group B (4.2% and 7.6% at 3 and 5 years, respectively) and with group A (9% and 18.2% at 3 and 5 years, respectively) (p = 0.0089). Ileocolonoscopy during the year after surgery was associated with a significantly reduced surgical recurrence rate in univariate and multivariate analysis (HR = 0.31, p = 0.0049). Conclusion: The implementation of an early ileocolonoscopy after surgery for Crohn's disease since early 2000 has been associated with a reduced surgical recurrence over the last 30 years.
