RESUMO
BACKGROUND: This study aimed to assess the distribution of esophageal inflammation in patients with eosinophilic esophagitis (EoE) and its impact on diagnosis and outcome. AIMS AND METHODS: Data from consecutive adult EoE patients who were followed-up at four Italian referral centers from October 2022 to October 2023 were retrospectively collected. RESULTS: One hundred forty-nine patients were included. Proximal EoE was observed in 8.1 % of patients; distal EoE in 27.5 %; and diffuse EoE in 64.4 %. Allergic rhinitis was more prevalent in distal and diffuse than proximal EoE (72.5 % vs. 61.5 % vs 33.3 %; P = 0.049). The prevalence of asthma, atopic dermatitis, oral allergy syndrome, and gastroesophageal reflux disease was not significantly different among the three EoE extent groups. Endoscopic inflammatory features at diagnosis were more prevalent in proximal EoE (91.7 % vs. 53.8 % distal [P = 0.01] vs. 66 % diffuse[P = 0.05]). No significant differences in fibrotic features and esophageal stenoses were observed. The clinical and histological remission rates after first-line therapy were comparable in all groups. CONCLUSION: Esophageal inflammation in EoE more frequently involves the entire esophagus, followed by isolated distal and proximal involvement. No clear correlation was observed between the histological extent of EoE at diagnosis and comorbidities or treatment response.
RESUMO
BACKGROUND: COVID-19 pandemic has profoundly changed the activities and daily clinical scenarios, subverting organizational requirements of our Gastroenterology Units. AIM: to evaluate the clinical needs and outcomes of the gastroenterological ward metamorphosis during the COVID-19 outbreaks in a high incidence scenario. METHODS: we compared the pertinence of gastroenterological hospitalization, modality of access, mortality rate, days of hospitalization, diagnostic and interventional procedures, age, Charlson comorbidity index, and frequency of SARS-CoV-2 infections in patients and healthcare personnel across the first and the second COVID-19 outbreaks in a COVID-free gastroenterological ward in the metropolitan area of Milan, that was hit first and hardest during the first COVID-19 outbreak since March 2020. RESULTS: pertinence of gastroenterological hospitalization decreased both during the first and, to a lesser degree, the second SARS-CoV2 waves as compared to the pre-COVID era (43.6, 85.4, and 96.2%, respectively), as occurred to the admissions from domicile, while age, comorbidities, length of stay and mortality increased. Endoscopic and interventional radiology procedures declined only during the first wave. Hospitalized patients resulted positive to a SARS-CoV-2 nasopharyngeal swab in 10.2% of cases during the first COVID-19 outbreak after a median of 7 days since admission (range 1-15 days) and only 1 out of 318 patients during the second wave (6 days after admission). During the first wave, 19.5% of healthcare workers tested positive for SARS-CoV-2. CONCLUSIONS: a sudden metamorphosis of the gastroenterological ward was observed during the first COVID-19 outbreak with a marked reduction in the gastroenterological pertinence at the admission, together with an increase in patients' age and multidisciplinary complexity, hospital stays, and mortality, and a substantial risk of developing a SARS-CoV-2 test positivity. This lesson paved the way for the efficiency of hospital safety protocols and admission management, which contributed to the improved outcomes recorded during the second COVID-19 wave.
