IgG4 and IgE anti-Strongyloides stercoralis as additional parameters in characterizing patients with diabetes from a hyperendemic area.

We report the detection of IgG, IgG1, IgG4 and IgE anti-Strongyloides stercoralis as complementary tool for screening in patients with diabetes in hyperendemic areas for strongyloidiasis. A panel of 119 serum samples were analyzed: 76 from patients with DM2 and 43 patients with other endocrine diseases and a positive correlation for total IgG levels with IgG4 (rs = 0.559; P = 0.024; n = 16) and IgG and IgE (rs = 0.585; P < 0.0001; n = 76) was found in the diabetes group.
