Abstract
Objective. Although disseminated nontuberculous mycobacterial infection is attributed to defects in the interleukin (IL)-12/interferon-γ circuit, the immunophenotype of idiopathic pulmonary nontuberculous mycobacterial (PNTM) disease is not well defined. Method. We phenotyped Th1, Th2, Th17, and Treg cytokines and colony-stimulating factor production from patients with idiopathic PNTM disease. Data were compared with healthy donors, cystic fibrosis (CF), and primary ciliary dyskinesia (PCD) patients with PNTM disease. Both supernatant cytokine production and intracellular cytokines expressed by various leukocyte subpopulations following mitogen and antigen stimulation were assayed by electrochemiluminescence–based multiplex immunoassay and flow cytometry, respectively. Results. Regardless of antigen or mitogen stimulation, neither intracellular nor extracellular Th1, Th2, and Treg cytokine levels differed between patients and controls. Th17 cells and IL-17A levels were lower in idiopathic PNTM patients, whereas monocyte granulocyte-macrophage colony-stimulating factor (GM-CSF) expression in response to NTM stimulation was higher compared with healthy donors. Besides, distinct cytokine responses following stimulation by Mycobacterium abscessus and Mycobacterium avium were observed consistently within each group. Conclusions. The IL-12/IFN-γ circuit appeared intact in patients with idiopathic PNTM disease. However, idiopathic PNTM patients had reduced Th17 response and higher mycobacteria-induced monocyte GM-CSF expression. ? 2019 Oxford University Press. All rights reserved.
