This study was designed to ascertain the role of anti-interferon (IFN)-ω and -α2 antibodies (AB) in diagnostics of type 1 autoimmune polyglandular syndrome (APS-1) and evaluate specificity and sensitivity of the HEK-Blue cells method used to detect these antibodies. The study included 34 patients presenting with APS-1 and 21 patients with focal alopecia. All 100% of the patients with APS-1 ehxhibited high titers of anti IFN-ωantibodies; 97% of them had anti IFN-a2 antibodies. These antibodies were not found in the patients with focal alopecia. It is concluded that the measurement of anti IFN-α and α2 antibodies with the use of HEK-Blue cells is a highly specific and sensitive method for diagnostics of APS-1.
