Life-threatening asthma attack during prolonged fingolimod treatment: case report
نویسندگان
چکیده
BACKGROUND Fingolimod (FTY) mediates bronchoconstriction by interacting with sphingosine-1-phosphate receptors. The majority of the reported adverse respiratory events occur during the first weeks of treatment. CASE PRESENTATION A 49-year-old woman developed a life-threatening asthma attack after 6 months of continuous FTY treatment. The adverse event required prolonged hospitalization, and the patient recovered without sequelae after FTY interruption. A history of previous airway hyperreactivity and a concurrent viral respiratory infection possibly acted as predisposing factors. CONCLUSION This first description of a severe, life-threatening asthma attack during prolonged FTY treatment suggests the need for long-term clinical surveillance, especially in patients with known predisposing factors.
