Fulminant psittacosis complicated with multiple organ dysfunction syndrome: a case report

The cases of fulminant psittacosis complicated with multiple organ dysfunction syndrome （MODS） have been rarely reported in China. In this article， clinical manifestations and treatment of a patient with fulminant psittacosis complicated with MODS were summarized and analyzed. The 80-year-old male patient developed respiratory failure in Emergency Department and received mechanical ventilation， which rapidly progressed into acute respiratory distress syndrome （ARDS） complicated with MODS. Metagenomic next-generation sequencing （mNGS） using bronchoalveolar lavage fluid （BALF） samples confirmed the pathogen of Chlamydia psittaci. Then， moxifloxacin， doxycycline and omadacycline were given， which yielded favorable efficacy and prognosis. The diagnosis and treatment of this patient suggests that fulminant psittacosis can be manifested with respiratory failure， severe pneumonia with rapid progression and MODS. Imaging manifestations consist of pneumonia， bronchial inflation sign and pleural effusion. mNGS can be p
