—Reactive arthritis induced by parasitic infestation is rare,1,2 but this condition has to be kept in mind since a specific antiparasitic treatment is effective. We describe herein a patient with reactive arthritis caused by Strongyloides stercoralis.
Report of a Case.
—A 31-year-old dental hygienist had an unremarkable medical or surgical history, except for a trip to Mexico three months before seeing us. He consulted us following the recent acute appearance of arthritis. The symptoms were polyarticular and symmetrical and principally involved the distal joints. The onset of arthritis had been accompanied by fever (temperature, 39.5°C) and asthenia. His condition improved following treatment with aspirin (acetylsalicylic acid) (3 g/d for three days) and at that time signs of arthritis were restricted to the right shoulder and knee. His erythrocyte sedimentation rate remained elevated; he had leukocytosis (18.0 × 109 cells per liter [18 000/mm3]) and
