Recurrence of Disseminated Mycobacterium avium Complex Disease in a Patient with Anti-Gamma Interferon Autoantibodies by Reinfection

摘要

We report a case of recurrent disseminated Mycobacterium avium complex (DMAC) disease with anti-gamma interferon autoantibodies. To our knowledge, this is the first reported case caused by reinfection with a separate isolate of M. avium. DMAC disease activity was monitored using serum IgG antibody titers against lipid antigens extracted from a MAC strain.
