[Acute respiratory insufficiency caused by hyperinfestation with strongyloides. BALF diagnosis and favourable...

Hyperinfestation with Strongyloides is a severe complication in immunodepressed patients. It may present with various clinical signs, notably acute respiratory failure. Diagnosis may be difficult, particularly when the strongyloidiasis is associated with septicaemia caused by Gram-negative organisms. We report a new case of hyperinfestation with Strongyloides in a patient treated for periarteritis nodosa. This case was remarkable on two scores: the diagnosis problem raised by the presence of intrapulmonary haemorrhages, and the favourable outcome of an acute and initially severe respiratory failure which had required assisted ventilation. The role played in the patient's cure by the doses of thiabendazole given and the duration of their administration is discussed.
