Disseminated nocardiosis with persistent neurological disease

BMJ Case Rep. 2024 Jan 9;17(1):e257935. doi: 10.1136/bcr-2023-257935.

Abstract

A man in his 80s with a history of sarcoidosis on chronic prednisone presented to the emergency department with several days of dyspnoea. A chest X-ray showed signs of pneumonia, and the patient was admitted. Blood and pleural fluid cultures grew Nocardia farcinica; therefore, the patient was started on treatment with trimethoprim-sulbactam and imipenem. Brain imaging showed evidence of dissemination of the infection to the central nervous system (CNS). The patient's admission was complicated by pleural effusions, acute kidney injury and pancytopenia, and therefore, his antibiotic regimen was ultimately transitioned from trimethoprim-sulfamethoxazole (TMP-SMX), meropenem and linezolid to imipenem and tedizolid. The patient received imipenem and tedizolid for the remainder of the admission. A repeat MRI of the brain was performed after 6 weeks of this dual antibiotic therapy, which unfortunately revealed persistent CNS disease. His regimen was then broadened to TMP-SMX, linezolid and imipenem. Despite these measures, however, the patient ultimately passed away from the infection.
