The Ag-TB levels of IL-17A, GM-CSF, together with the PHA levels of TNF-α, GM-CSF and, IL-13, and median hemoglobin levels showed significant differences between active TB groups (p = 0.009, p = 0.027, p = 0.027, p = 0.040 and p = 0.042, p = 0.006, respectively). This evidence concerns the gene IL13 and tuberculosis.
