CRP and hypereosinophilic syndrome: Positive correlations were found between CRP and levels of parasitemia (ρ = 0.444), CRP and HES (ρ = 0.406), as well as levels of parasitemia and HES (ρ = 0.348), while negative correlations were observed between levels of antibodies and parasitemia (ρ = −0.666), as well as antibody levels and HES (ρ = −0.652) (P < 0.001 each).
