IGHE and infection: Anti-TpmII.3 IgE levels were significantly negatively correlated with re-infection intensity 2 years post-treatment (β = −0.64; P < 0.05, Table 3), whilst anti-TpmII.7 IgG4 levels were significantly positively correlated with re-infection intensity (β = 0.14; P < 0.05, Table 4).
