Two cases of severe psittacosis pneumonia complicated with Coronavirus disease 2019

Abstract

Abstract Chlamydia psittaci complicated with Coronavirus disease 2019(COVID-19) infection is rarely reported at present, and the severe pneumonia caused by them can significantly prolong the hospitalization time and even affect the prognosis of patients, so early diagnosis and accurate treatment are needed. Two patients with severe pneumonia caused by Chlamydia psittaci during the opening of the epidemic situation of COVID-19 in China were reported. The main manifestations were high fever, respiratory failure and multiple organ dysfunction. The diagnosis of Chlamydia psittaci complicated with COVID-19 infection was diagnosed by metagenome next-generation sequencing (mNGS). One patient was discharged from hospital after treatment with azithromycin combined with moxifloxacin for anti-infection, mechanical ventilation, antiviral, anticoagulant, anti-inflammatory and symptomatic support, and the other patient died of underlying disease complicated with multiple organ failure. Through the treatment of these two patients, the author also summarized the relevant clinical characteristics and experience of severe pneumonia caused by parrot fever combined with COVID-19 infection for scholars to read and reference. The aim is to improve the medical staff's early identification and timely treatment of this kind of disease.
