The hospital records of 213 outpatients from Bangkok, Thailand, infected with Strongyloides stercoralis as determined by stool inspections were examined retrospectively for the different clinical presentations ascribed to patients with HIV, those with chronic illness, those who used immunosuppressant drugs and relatively healthy subjects. For HIV patients with strongyloidiasis, the most common symptoms were chronic diarrhea, fever, persistent coughing and loss of weight, but only the first three symptoms were significantly different from other immunocompromised hosts. For healthy patients with strongyloidiasis, acute diarrhea and abdominal pain were the most frequent symptoms. Moreover, the peripheral eosinophil blood count was significantly lower (P = 0.004) in the HIV patients than in any of the other subsets. Males were more common than females across all categories. While the average age of all subjects was 48.3 ± 16.4 years, the strongyloidiasis patients with chronic illness were significantly older (56.8 ± 13.5 years) than those in the other groups. This study may suggest that strongyloidiasis is commonly found in geriatric males, and that the patients most at risk for S. stercoralis infection are HIV patients. This is the first report of the different clinical presentations of intestinal strongyloidiasis in various groups of patients with impaired immunity.
