Omadacycline treatment of severe Chlamydia psittaci pneumonia with septic shock diagnosed via metagenomic next-generation sequencing
Abstract
INTRODUCTION
Parrot fever, caused by Chlamydia psittaci, is a zoonotic disease typically treated with tetracyclines. Omadacycline, a novel aminomethyl tetracycline, has limited reports on its efficacy in severe Chlamydia psittaci pneumonia in the literature.
CASE PRESENTATION
We present a case of a patient with severe Chlamydia psittaci pneumonia showing symptoms of chills, high fever, shock, hepatic and renal insufficiency, and acute respiratory failure with copious yellow watery sputum. Chlamydia psittaci was confirmed by metagenomic next-generation sequencing (mNGS). Despite initial treatment with moxifloxacin and doxycycline, the patient did not improve and was subsequently discharged after receiving omadacycline.
CONCLUSIONS
Our findings highlight the potential of mNGS for rapid diagnosis of Chlamydia psittaci pneumonia and suggest omadacycline as a potential therapeutic option for severe cases that do not respond to conventional treatment.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
