Cytokines have been studied more in depth in hematological malignancies; however, in these studies, a noted association has been made that higher levels of interleukin 10 (IL-10) were found in BAL of patients who also had IPA (Cunha et al., 2017) or worst outcomes in patients with persistently elevated IL-6 and IL-8 (Chai et al., 2010). Here, CXCL8 is linked to hematologic disorder.
