NTM-LD leads significant morbidity and mortality, around 25% within 5 years, but the treatment rate is low because the course of NTM-LD is indolent, especially in nodular-bronchiectatic (NB) form. However, there is no biomarker proven for predicting the progression in NB form of NTM-LD. Recently, it has been reported that the ratio of membrane-form programmed death-1 (PD-1) expressed T cells increased in patients with NTM-LD and it was associated with disease severity and progression. The mechanism has been speculated as a \"immune exhaustion\". In contrast to PD-1 expressed in cell membrane, soluble-form PD-1 is another biomarker that can be easily detected in serum. We recently reported that soluble PD-1 significantly correlated with cavitary lesion and disease progression in patients with NB-form NTM-LD in Taiwan. However, this has not been validated in other countries and ethnicities. Furthermore, the usefulness of soluble PD-1 in diagnosis and predicting mortality warrants further studies.",[60],"Nontuberculous Mycobacterial Lung Disease","2026-06-07",{"date":63,"type":64},"2026-06-10","ACTUAL",{"date":66,"type":64},"2023-01-31",{"date":68,"type":56},"2026-12-31",{"name":5,"class":6},1]
