Case Report: Refractory Acute Respiratory Distress Syndrome Supported by Extracorporeal Membrane Oxygenation due to Coinfection with Chlamydia pneumoniae and Leptospirosis in Reunion Island.

Infection with Leptospira spp. is common in Réunion, a tropical island in the Indian Ocean. However, respiratory coinfections between strains of Leptospira spp. and other microorganisms are rarely described. Here, we describe the first reported case of coinfection between Leptospira spp. and Chlamydia pneumoniae, responsible for refractory acute respiratory distress syndrome requiring extracorporeal membrane oxygenation with a favorable outcome. In a case of leptospirosis with severe respiratory illness, testing for respiratory coinfection, especially with atypical pathogens, could explain the seriousness of the clinical condition and lead to specific treatment.

Emergency air evacuation of patients with acute respiratory failure due to SARS-CoV-2 from Mayotte to Reunion Island.

ABSTRACT: In February 2021, an explosion of cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia overwhelmed the only hospital in Mayotte. To report a case series of patients with acute respiratory failure (ARF) due to SARS-CoV-2 who were evacuated by air from Mayotte to Reunion Island.This retrospective observational study evaluated all consecutive patients with ARF due to SARS-CoV-2 who were evacuated by air from Mayotte Hospital to the intensive care unit (ICU) of Félix Guyon University Hospital in Reunion Island between February 2, and March 5, 2021.A total of 43 patients with SARS-CoV-2 pneumonia were evacuated by air, for a total flight time of 2 hours and a total travel time of 6 hours. Of these, 38 patients (88.4%) with a median age of 55 (46-65) years presented with ARF and were hospitalized in our ICU. Fifteen patients were screened for the SARS-CoV-2 501Y.V2 variant, all of whom tested positive. Thirteen patients (34.2%) developed an episode of severe hypoxemia during air transport, and the median paO2/FiO2 ratio was lower on ICU admission (140 [102-192] mmHg) than on departure (165 [150-200], P = .022). Factors associated with severe hypoxemia during air transport was lack of treatment with curare (P = .012) and lack of invasive mechanical ventilation (P = .003). Nine patients (23.7%) received veno-venous extracorporeal membrane oxygenation support in our ICU. Seven deaths (18.4%) occurred in hospital.Emergency air evacuation of patients with ARF due to SARS-CoV-2 was associated with severe hypoxemia but remained feasible. In cases of ARF due to SARS-CoV-2 requiring emergency air evacuation, sedated patients receiving invasive mechanical ventilation and curare should be prioritized over nonintubated patients. It is noteworthy that patients with SARS-CoV-2 pneumonia related to the 501Y.V2 variant were very severe despite their young age.
