We report on 3 children undergoing treatment for acute lymphoblastic leukemia (ALL), who developed systemic nontuberculous mycobacterial (NTM) infections. All 3 patients were treated successfully with 5 months or less of antimicrobial therapy and completed their chemotherapy with no further recurrence of their NTM infection. NTM infections in some children with ALL may be successfully treated with antimicrobial agents without necessarily compromising the ALL treatment. The optimal duration of therapy for NTM remains unclear, but may be shorter than previously reported.

Background: Due to its increasing prevalence and suboptimal treatment, non-tuberculous mycobacterial (NTM) infection is an emerging problem in patients with cystic fibrosis (CF). Detailed description of regional NTM prevalence and distribution, and identification of predictors of NTM acquisition in CF are essential to optimise treatment and surveillance guidelines.
Methods: A retrospective, multi-center analysis was conducted between the years 2020 and 2022 on data from 232 adult patients registered in the Hungarian CF Registry in 2022.

Background: Hemoptysis is one of the major symptoms in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). However, its prevalence, incidence, and impact on long-term prognosis remain uncertain. We evaluated the incidence of clinically significant hemoptysis, and determined its association with mortality in patients with NTM-PD.

Interferon-gamma (IFN-γ) autoantibody syndrome is an emerging clinical entity that has been associated with disseminated non-tuberculous mycobacterial infection (dNTM) particularly in healthy young people, a population not previously thought to be at particular risk. A 29-year-old South-East Asian man presented with several weeks of fever, cough, lymphadenopathy, and constitutional symptoms while working on an international cargo ship, deteriorating rapidly with a sepsis-like syndrome. Eventually lymph node and sputum cultures revealed a diagnosis of dNTM infection with growth of both Mycobacterium persicum and Mycobacterium abscessus.
