Serum concentrations of G-CSF (p=0.0126), IL-1β (p=0.0022), IL-4 (p=0.0003), IL-7 (p=0.0003), IL-8 (p=0.0179), IL-13 (p=0.0009), IP-10 (p=0.0126) and TNF-α (p=0.0166) were all significantly lower in SARS-CoV-2 seropositive TB patients compared to seronegative. This evidence concerns the gene IL4 and tuberculosis.
