ABSTRACT
Introduction: The COVID-19 pandemic caused many changes in gastrointestinal endoscopy units. Aim: To describe the changes that occurred in a gastrointestinal endoscopy unit of a hybrid hospital during the COVID-19 pandemic. Material and methods: We performed a retrospective study of endoscopies performed in the first year of the COVID-19 pandemic. We collected and described the data of interest to the study, which is presented with numbers and percentages or measures of central tendency and dispersion as appropriate. Fisher's exact test or the χ2 test were used as appropriate. Results: A total of 507 procedures were performed. There was a 92.5% reduction in the performance of endoscopic procedures. In all, 77 (15%) procedures were performed on patients with COVID-19. The most frequent procedures were esophagogastroduodenoscopy (EGD), colonoscopy, and endoscopic retrograde cholangiopancreatography (ERCP). The main indications were gastrointestinal bleeding, placement of enteral accesses, and alterations in the biliary and pancreatic ducts. Of these, 37 (48%) were therapeutic. Patients with COVID-19 were more susceptible to the development of complications. Conclusions: During the first year of the COVID-19 pandemic, the number of endoscopic procedures performed decreased significantly. The procedures most often required were EGD, colonoscopy, and ERCP, mainly indicated by gastrointestinal bleeding, placement of enteral accesses, and alterations of the bile and pancreatic ducts.
ABSTRACT
BACKGROUND: Data regarding outcome of Coronavirus disease 2019 (COVID-19) in vaccinated patients with autoimmune hepatitis (AIH) are lacking. We evaluated the outcome of COVID-19 in AIH patients who received at least one dose of Pfizer- BioNTech (BNT162b2), Moderna (mRNA-1273) or AstraZeneca (ChAdOx1-S) vaccine. PATIENTS AND METHODS: We performed a retrospective study on AIH patients with COVID-19. The outcomes of AIH patients who had acute respiratory syndrome coronavirus 2 (SARS-CoV-2) breakthrough infection after at least one dose of COVID-19 vaccine were compared to unvaccinated patients with AIH. COVID-19 outcome was classified according to clinical state during the disease course as: (i) no hospitalization, (ii) hospitalization without oxygen supplementation, (iii) hospitalization with oxygen supplementation by nasal cannula or mask, (iv) intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v) ICU admission with invasive mechanical ventilation or (vi) death, and data was analyzed using ordinal logistic regression. RESULTS: We included 413 (258 unvaccinated and 155 vaccinated) patients (81%, female) with a median age of 52 (range: 17-85) years at COVID-19 diagnosis. The rates of hospitalization were (36.4% vs. 14.2%), need for any supplemental oxygen (29.5% vs. 9%) and mortality (7% vs. 0.6%) in unvaccinated and vaccinated AIH patients with COVID-19. Having received at least one dose of SARS-CoV-2 vaccine was associated with a significantly lower risk of worse COVID-19 severity, after adjusting for age, sex, comorbidities and presence of cirrhosis (adjusted odds ratio [aOR] 0.18, 95% confidence interval [CI], 0.10-0.31). Overall, vaccination against SARS-CoV-2 was associated with a significantly lower risk of mortality from COVID-19 (aOR 0.20, 95% CI 0.11-0.35). CONCLUSIONS: SARS-CoV-2 vaccination significantly reduced the risk of COVID-19 severity and mortality in patients with AIH.
