Haemophagocytic syndrome caused by disseminated nontuberculous mycobacterial infection

Abstract

A female patient in her 30s presented to the emergency department with a 10-day history of fever, weakness and diaphoresis. Subsequent investigations revealed a diagnosis of haemophagocytic syndrome, secondary to disseminated non-tuberculous mycobacterial infection affecting the bone marrow, lungs, lymph nodes and skin. The bone marrow culture confirmed the presence ofMycobacterium aviuminfection. The patient’s haemophagocytic syndrome was managed using the HLH-2004 chemoimmunotherapy, andM. aviuminfection was treated with a combination of clarithromycin, ethambutol, rifampicin, ciprofloxacin and amikacin. Throughout her hospitalisation, the patient faced several serious complications arising from both the medications and the prolonged hospital stay (lasting 12 months). However, these complications were promptly identified and effectively managed through a multidisciplinary and comprehensive approach. This approach was crucial in achieving a favourable patient outcome and successful recovery.
