    Abstract Nontuberculous mycobacteria (NTM) pulmonary disease is a chronic progressive pulmonary infectious disease caused by low virulence pathogens. The existence of host susceptibility to NTM infection has been recognized from a high incidence among Asians compared to other populations in the United States, a high incidence among slender, middle-aged women, and the presence of familial clusters. Recent whole exome sequencing and genome-wide association studies have identified immune, CFTR, cilia, connective tissue and ion homeostasis genes as host susceptibility genes. Large-scale international collaborative studies and functional analyses are expected to elucidate host susceptibility in the future.

    Abstract Obesity is a risk factor for disease severity in individuals with coronavirus disease (COVID-19). However, the increased susceptibility of this population to COVID-19 is unclear. We outline several underlying mechanisms that may explain the relationship between obesity and COVID-19 severity. Obesity has an adverse effect on respiratory physiology because increased intra-abdominal adipose tissue can interfere with lung expansion, resulting in reduced lung compliance. Further, fat accumulation in the soft tissue of the pharynx can increase inspiratory resistance, and obesity may be associated with sleep apnea. Obesity is associated with several defects in cell-mediated immunity, including increased levels of pro-inflammatory cytokines. Impaired adipocyte-mediated immune function results in chronically high leptin levels, low adiponectin levels, and anti-inflammatory adipokines. Reduced physical activity can impair several steps of the immune response to viruses. Obesity also promotes a hypercoagulable state, leading to severe consequences. These factors may synergistically play a role in promoting the severity of the disease in obese individuals. A better understanding of the mechanisms by which obesity contributes to the severity of COVID-19 is important for developing more effective treatments.

    Abstract Background: Immune checkpoint inhibitors (ICIs) have become one of the standard treatment options for solid tumours; however, treatment-related adverse events, including pneumonitis, sometimes disrupt the ongoing treatment. To evaluate the impact of ICI addition on the risk of pneumonitis, a meta-analysis was conducted.
    Methods: Phase III randomised controlled trials comparing ICIs and conventional therapy with conventional therapy alone were selected by searching databases, including PubMed, Embase, Web of Science and Cochrane Library. The odds ratio (OR) of any grade and grade III-V pneumonitis was calculated. Meta-analysis was performed to compare the incidence of pneumonitis between the treatment arm with additional ICIs and the arm with conventional therapy.
    Results: A total of 25 randomised controlled trials (RCTs) representing 16,343 patients for grade I-V and 23 RCTs with 15,006 patients for grade III-V pneumonitis were analysed. Adding ICIs was associated with a significant increase in pneumonitis (grade I-V: OR, 2.67, 95% confidence interval [CI]: 2.12-3.37, grade III-V: OR, 1.83, 95% CI: 1.26-2.65). In subgroup analyses based on the mechanism of action of ICIs, cancer types (lung and non-lung cancer) and each ICI, no significant difference in heterogeneity was observed.
    Conclusions: Adding ICIs to the conventional treatment for solid tumours significantly increased both grade I-V and grade III-V pneumonitis regardless of the mechanisms of ICIs and cancer type. These results would be helpful for oncologists to choose the appropriate treatment options using ICIs, particularly for patients with known risk factors of pneumonitis or interstitial lung disease.
