title: L-dopa malabsorption in a parkinsonian patient with Strongyloides stercoralis duodenitis.
abstract: We report a parkinsonian patient initially responding to L-dopa who developed a severe loss of drug efficacy due to Strongyloides stercoralis duodenitis. The patient was put on mebendazole and metronidazole, and the parasitosis abated, allowing L-dopa reduction by 33%. Our patient illustrates the advisability of searching for Strongyloides stercoralis when L-dopa malabsorption is suspected in Parkinson's disease.
