Blood analysis, flow cytometry and interleukin-5 responses to Strongyloides stercoralis larval antigens A peripheral blood sample was obtained at enrollment from all strongyloidiasis patients.

Samples were analyzed before HTLV-1 status was known. Numbers represent median of all parameters analyzed. Complete peripheral blood cell count showed lower hemoglobin and hematocrit levels in the HTLV-1 co-infected group. White blood cell, neutrophil, eosinophil, and lymphocyte proportions were not significantly different among groups, although a tendency to lower absolute eosinophil count was observed in the HTLV-1 infected group. Regulatory T cells were significantly increased in patients with strongyloidiasis and HTLV-1 co-infection (* = p
