Our results show a probable influence of gene polymorphisms, namely IL-4R alpha and IL-10 on ENA-78 BALF levels in sarcoidosis, IL-6 on ENA-78 BALF levels in HP and IL-1-beta on IL-1RA BALF values in the IPF group.
The serum levels of IP-10 were significantly increased only in patients with stages I and II sarcoidosis, while BAL fluid levels of ENA-78 were increased only in stage III sarcoidosis.
