Geometric mean levels of IgE in the study population were 1,004 IU/mL (range 12–22,608 IU/mL) and were similar between the infection (infection/no treatment, 1,315 IU/mL vs. infection/treatment, 1,566 IU/mL, P = 0.34) and the no infection groups (no infection/no treatment, 825 IU/mL vs. no infection/treatment, 599 IU/mL, P = 0.09). Here, IGHE is linked to infection.
