Interstitial Lung Disease Around the World

Interstitial Lung Disease (ILD) comprises of a broad spectrum of diseases, with different underlying disease mechanisms, disease behaviours and outcomes. This heterogeneity in disease is partly due to varying interactions between environmental and host factors. For instance, factors such as exposure, air-pollution or infections may be the inciting triggers, whereas host factors including age, genetic predisposition and auto-immunity influence the risk of developing ILD. Furthermore, access to diagnosis, care and treatment options also impact disease outcomes and health related quality of life. Many of these factors vary in severity and frequency around the globe. In this Research Topic, we strive to identify differences and similarities across the globe for many "hot topics" in ILD.

Accordingly, this Research Topic aims to achieve a greater insight into the differences and similarities in ILD around the world for a wide range of topics. Furthermore, we wish to promote collaborations between scientist and clinicians from different continents. We strongly encourage a combination of more established and rising talents, and representation of different continents in the authorship.

Here, we accept clinical trials, original research, systematic reviews and mini-reviews that assess the differences and similarities in ILD treatment and outcomes around the world, including but not limited to the following topics:

• Genetics
• Registries
• Access to care
• Quality of life
• Hyper-sensitivity pneumonitis
• Microbiome
• Acute exacerbations
• Social media
• Air-pollution
