Strongyloides is an helmintic infection that may induce bronchospasm during
systemic migration of larvae. We report a case of a 60 years old man origi
nating from Caribbean who had corticodependent asthma since 30 years. He wa
s hospitalised for severe exacerbation that worsen when steroid dosage was
increase. Sputum examination revealed the presence in great number of Larva
e of Strongyloides stercoralis. A good clinical evolution was achieved afte
r specific antihelmintic treatment. Later on, it was even possible to stop
completely steroid treatment. This clinical case demonstrates the interest
to look for Strongyloides superinfection in asthmatic patients that worsen
when receiving increasing dose of steroids. This is particularly important
for patients who have resided, even many years earlier; in areas where inte
stinal helmintic infection are endemic.
