Background and study aims Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), has posed a pandemic threat to global health and has challenged health care system in all affected countries. Patients and methods This is a combined study including a descriptive part about the changes in the daily work routine of an Interdisciplinary Endoscopic Unit (IEU) and a prospective analysis of patients tested positive for SARS-CoV-2 who required endoscopic interventions. Conclusively, we present the finding of a point-prevalence analysis in the staff of the IEU. Results We present effects of the COVID-19-related restructuring of processes in our interdisciplinary endoscopy unit (IEU) with respect to cancelation of examinations, relocation of staff to other departments, impact of SARS-CoV-2 on medical staff of the IEU, and supply of protective clothing. Additionally, we analyzed the cohort of COVID-19 patients: Sixteen endoscopic interventions were done in ten patients. In all patients with confirmed infection with SARS-CoV-2, emergency endoscopies were required for relevant bleeding situations. Re-endoscopies were required only in critically ill COVID-19 patients. Conclusions The restructuring of processes in the IEU was feasible in short time, effective, and can also be applied broadly at least in developed countries [Garbe et al. in Gastroenterology 159:778–780, 2020; Repici A, Pace F, Gabbiadini R, Colombo M, Hassan C, Dinelli M, Group IG-CW, Maselli R, Spadaccini M, Mutignani M, Gabbrielli A, Signorelli C, Spada C, Leoni P, Fabbri C, Segato S, Gaffuri N, Mangiavillano B, Radaelli F, Salerno R, Bargiggia S, Maroni L, Benedetti A, Occhipinti P, De Grazia F, Ferraris L, Cengia G, Greco S, Alvisi C, Scarcelli A, De Luca L, Cereatti F, Testoni PA, Mingotto R, Aragona G, Manes G, Beretta P, Amvrosiadis G, Cennamo V, Lella F, Missale G, Lagoussis P, Triossi O, Giovanardi M, De Roberto G, Cantu P, Buscarini E, Anderloni A, Carrara S, Fugazza A, Galtieri PA, Pellegatta G, Antonelli G, Rosch T, Sharma P (2020) Endoscopy units and the COVID-19 Outbreak: a Multi-Center Experience from Italy. Gastroenterology;]. The endoscopy-related rate of SARS-CoV-2 infection of staff is low, but supply of protective equipment is crucial for this. Endoscopic procedures in COVID-19 patients were not directly related to SARS-CoV-2 infection, but to other underlying diseases or typical complications of long-term ICU treatment.

Immune‐checkpoint inhibitors (ICIs) provide a promising treatment option for advanced tumors including small cell lung cancer (SCLC). Nevertheless, in addition to immune‐related adverse events (irAEs), an increased risk of infection including tuberculosis has been previously described. Here, we report a case of long‐term remission of a patient with SCLC after reactivation of lung tuberculosis following ICI therapy. Our case illustrates the complexity of ICI‐associated immune modulation in tuberculosis. Since new lesions in lung cancer patients are commonly associated with tumor progression, infections with mycobacterial tuberculosis may be underdiagnosed in lung cancer.
