[Extraintestinal strongyloidiasis in the acquired immunodeficiency syndrome].
A 41-year old man of Brazilian origin, suffering from AIDS for one year, fell ill with pyrexia of over 39 degrees C, dyspnoea, chest pain and deterioration in his general condition. At the same time he noted a discrete skin eruption, mainly on the upper limbs. Diarrhoea began later. A chest radiograph revealed bilateral infiltrates. The blood showed leucocytosis (11,000/microliters) with pronounced increase of eosinophil granulocytes (47.5%). Alkaline phosphatase was raised to 170 U/l. Suspicion of strongyloidiasis was confirmed by the discovery of numerous Strongyloides stercoralis larvae in the faeces. A few days after starting treatment with mebendazole, 400 mg daily, he felt better and the diarrhoea stopped. However, as the lung infiltrates remained unchanged and hilar lymph node enlargement now appeared, the dose of mebendazole was raised to 2500 mg daily. The abnormal findings then cleared up: Strongyloides stercoralis larvae ceased to be demonstrable and the patient gained 10 kg in weight.
