Open Forum Infect Dis. 2022 Dec 28;10(1):ofac700. doi: 10.1093/ofid/ofac700. eCollection 2023 Jan.

Abstract

We report a case of a person with human immunodeficiency virus with disseminated Mycobacterium avium infection, in whom antiretroviral therapy combined with all drugs of anti-M avium activity failed to clear the pathogen. After PD-1 inhibitor treatment, T-cell exhaustion was reversed and M avium-specific T-cell response was boosted, together with M avium clearance.
