We report adjunct treatment of (interferon) IFN-α2b (Intron-A) in a patient with complete interferon-γ receptor R1 (IFNGR1) deficiency suffering from disseminated infection with Mycobacterium avium complex (MAC) resistant to multiple anti-mycobacterial agents. A low dose of IFN-α2b (3 × 106 units/m2 three times weekly subcutaneously) successfully attenuated progressive hepatosplenomegaly and abdominal/ retroperitoneal/pelvic lymphadenopathy, although the patient continued to be mycobacteremic. This is the first report of a complete IFNGR1 deficiency treated with adjuvant IFN-α2b for disseminated MAC infection.
