[Update 2021: Pulmonary Sequelae of COVID-19 Pneumonia]. / Update 2021: Pulmonale Folgen nach COVID-19-Pneumonie.

Acute COVID-19 pneumonia may result in persistent changes with various imaging and histopathological patterns, including organizing pneumonia and pulmonary fibrosis. In addition, SARS-CoV-2 infection is associated with increased risk of pulmonary vascular endothelialitis and thrombosis. Herein, current findings on pulmonary consequences of COVID-19 with implications for clinical management are summarized based on a selective literature review.

[Post-COVID sequela of the lung - follow up and treatment]. / Post-COVID und die Lunge.

Most people recover completely after an acute infection with the novel corona virus SARS-CoV2. But some people continue to experience symptoms after their recovery. This phenomenon is called post-acute or long-COVID (from week 4 after the infection up to week 12) and persistent post-COVID (symptoms for effects that persist 12 or more weeks after onset). The exact processes that cause long COVID remain unknown.Most of those patients suffer from long-term symptoms of lung damage, including breathlessness, coughing, fatigue and limited ability to exercise. Today, 18 months after the first infections in Europe we have access to the first practical guidelines for the long-/post-COVID syndrome. Further on first prospective studies analysing the incidence of post-COVID are now available.In this review we will discuss some questions about treatment and follow up of patients suffering from pulmonary sequelae after their COVID-19 infection, based on the actual literature.

Detection of a COVID-19 cluster by universal SARS-CoV-2 testing in a geriatric hospital and implications for infection control management.

Hospital-level COVID-19 testing strategies may require rapid changes depending on the dynamics of local epidemiology. A COVID-19 outbreak in a hospital near the authors' institution, a Geriatric Medicine centre in Berlin, Germany, prompted the implementation of comprehensive SARS-CoV-2 testing. Serial nasopharyngeal swabs were collected from all patients and staff and analysed for SARS-CoV-2 virus RNA using quantitative real-time PCR. In total, 11 of 84 patients (13.1%) and 1 of 147 employees (0.68%) tested positive. Of the 11 positive patients, 9 (81.8%) were asymptomatic at the time of testing. The data were used as the basis for adjusting local COVID-19 containment measures. Only one staff-to-staff transmission was observed, and there was no patient-to-patient, patient-to-staff or staff-to-patient transmission. Three patients infected with SARS-CoV2 died, two deaths being attributable to advanced malignant disease and one to COVID-19-associated myocarditis. In conclusion, universal SARS-CoV-2 testing revealed a cluster of predominantly asymptomatic infections, enabled appropriate local COVID-19 containment decisions and presumably contributed to the prevention of in-hospital SARS-CoV-2 transmission.

[COVID-19: A Pneumological Point of View - Long-Term Sequelae of COVID-19 - Implications For Follow-up In Respiratory Medicine]. / COVID-19 aus Sicht der Pneumologie ­ Langzeitfolgen und Implikationen für die pneumologische Nachsorge.

The long-term sequelae of COVID-19 on are not yet predictable. Radiological and histopathological data on COVID-19 and observational studies after the SARS-CoV-1 pandemic 2003/2004 suggest that in a proportion of COVID-19 patients, functional limitations due to pulmonary fibrosis and other patterns of lung damage may persist. Systematic follow-up, based on prudent pulmonary function testing, is warranted for the correct diagnosis, graduation and treatment of the underlying pathology at an early stage. This review summarizes the potential spectrum of Post-COVID-19 pulmonary disease patterns and provides recommendations for the follow-up care of COVID-19 patients in the field of respiratory medicine.
