ABSTRACT

The COVID-19 pandemic has notably increased the need for prolonged mechanical ventilation (MV) in patients with respiratory failure. This has increased the risk of extensive tracheal injury (ETI) associated with life-threatening complications in complex cases. Furthermore, tracheal injury treatment in patients with COVID-19 has not been described yet. Three patients with COVID-19 and ETI who required MV between April and November 2020 were included. A multistep approach was performed to restore tracheal integrity with a custom-remodeled stent and tracheostomy tube placement to allow ventilatory support. Efficient MV with no residual air leaks was obtained in all cases. One patient died 6 weeks after the procedure due to COVID-19 lung damage. Two patients have completely been weaned from MV. This multistep procedure could be used to maintain ventilatory support in the case of ETI, working as a bridge to subsequent surgery when clinical conditions improve.

ABSTRACT

OBJECTIVE: Interactions between SARS-CoV-2 and pharyngeal associated lymphoid tissue are thought to influence the manifestations of COVID-19. We aimed to determine whether a previous history of tonsillectomy, as a surrogate indicator of a dysfunctional pharyngeal associated lymphoid tissue, could predict the presentation and course of COVID-19. METHODS: Multicentric cross-sectional observational study involving seven hospitals in Northern and Central Italy. Data on the clinical course and signs and symptoms of the infection were collected from 779 adults who tested positive for SARS-CoV-2, and analysed in relation to previous tonsillectomy, together with demographic and anamnestic data. RESULTS: Patients with previous tonsillectomy showed a greater risk of fever, temperature higher than 39°C, chills and malaise. No significant differences in hospital admissions were found. CONCLUSIONS: A previous history of tonsillectomy, as a surrogate indicator of immunological dysfunction of the pharyngeal associated lymphoid tissue, could predict a more intense systemic manifestation of COVID-19. These results could provide a simple clinical marker to discriminate suspected carriers and to delineate more precise prognostic models.
