Psittacosis: diagnosis and management of severe pneumonia and multi organ failure

Abstract

Two patients were admitted directly to our Intensive Care Unit in acute respiratory failure due to pneumonia with septicaemic shock, renal and hepatic impairment. Sputum and blood cultures failed to grow any organisms and despite broad spectrum antibiotic therapy for 7 days, neither patient improved. Diagnosis of the rare pneumonic form of psittacosis was made following a raised titre. After treatment with tetracyclines, both patients made a rapid recovery. Retrospective direct questioning revealed that they had close contact with psitacine birds.
