| Abstract |
|
Nontuberculous mycobacterial pulmonary disease (NTM-PD) arises from the exposure of susceptible hosts to a diverse group of environmental mycobacteria. The emphasis on non-pharmacological strategies is motivated by widespread presence of nontuberculous mycobacteria (NTM) in various environments and the inconsistent success rates of pharmacological treatments. Modifiable factors contributing to NTM-PD development include impaired airway clearance, low body mass index, gastroesophageal reflux disease, and exposure to NTM habitats. This suggests that lifestyle and environmental modifications could affect disease development and progression.
The review highlights several modalities that can modify the risk factors. Airway clearance techniques, informed by the "gel-on-brush" model of the bronchial epithelium, aims at enhancing mucociliary clearance and have potential in alleviating symptoms and potentially improving lung function. The impact of nutritional status is also examined, with a lower body mass index linked to an increased risk and progression of NTM-PD, indicating the importance of targeted nutritional support. Additionally, the theoretical and epidemiological links between gastroesophageal reflux disease and NTM-PD advocates for careful management of reflux episodes. Understanding the risk of NTM transmission through environmental exposure to contaminated water and soil is also crucial. Strategies to mitigate this risk, including effective water management and minimizing soil contact, are presented as vital preventive measures.
In conclusion, the review supports the inclusion of non-pharmacological treatments within a comprehensive NTM-PD management strategy, alongside conventional pharmacological therapies. This integrated approach seeks to improve the overall understanding and handling of NTM-PD. |
