Strongyloides Stercoralis infection associated with repititive bacterial meningitis and SIADH: a case report

Strongyloidiasis is an infection by the intestinal parasite Strongyloides Stercoralis, which usually stays asymptomatic. In some situations a hyperinfection or disseminated disease can occur. We report a case of a 49-year-old Congolese man with a medical history of 5 episodes of bacterial meningitis, who presents himself with a paralytic ileus and a low serum sodium. A Strongyloides hyperinfection with a syndrome of inappropriate secretion of the antidiuretic hormone (SIADH) was diagnosed. After treatment with ivermectine the abdominal symptoms subsided and the serum sodium returned to normal values. In comparison to other case reports our patient had no respiratory or gastrointestinal symptoms during the episodes of bacterial meningitis. Screening for Strongyloides stercoralis is indicated in patients with unexplained SIADH, bacterial meningitis or bacterial septicaemia, who originally come from endemic countries.
