Abstract:
Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is characterised by fever, rash, eosinophilia and organ damage that develops 2-6 weeks after the initiation of a medication. We report a case of DRESS syndrome in a 79-year-old man that developed after the introduction of rifabutin, ethambutol and clarithromycin used to treat Mycobacterium avium complex (MAC) vertebral osteomyelitis. This case highlights treatment and management challenges in a patient with known MAC vertebral osteomyelitis requiring prolonged steroids. Steroids are the mainstays of treatment for moderate to severe cases of DRESS syndrome. Initiation of steroids for the treatment of DRESS syndrome among patients with concomitant infections requires multidisciplinary collaboration for optimal management.
Insights
Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) is a severe reaction to medication. This case shows DRESS developing from MAC vertebral osteomyelitis treatment, highlighting complex management needs.
Area of Science:
- Pharmacovigilance
- Infectious Diseases
- Dermatology
Background:
- Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a severe, idiosyncratic drug reaction.
- It typically manifests 2-6 weeks post-medication initiation with fever, rash, eosinophilia, and organ damage.
- Mycobacterium avium complex (MAC) vertebral osteomyelitis requires multi-drug therapy, often including ethambutol, clarithromycin, and rifabutin.
Observation:
- A 79-year-old male developed DRESS syndrome.
- The reaction occurred after initiating treatment for MAC vertebral osteomyelitis with rifabutin, ethambutol, and clarithromycin.
- The patient required prolonged corticosteroid therapy for DRESS management.
Findings:
- This case illustrates a rare presentation of DRESS syndrome linked to MAC treatment.
- Management was complicated by the need for prolonged steroids in a patient with a concurrent infection.
- Multidisciplinary collaboration is crucial for managing DRESS in patients with co-existing infections.
Implications:
- Highlights the importance of recognizing DRESS syndrome in patients treated for MAC vertebral osteomyelitis.
- Emphasizes the challenges of steroid management in DRESS patients with concomitant infections.
- Underscores the need for a collaborative approach involving infectious disease specialists, dermatologists, and pharmacists for optimal patient outcomes.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
