BERTHA studys primary objective is to characterize Rheumatoid Arthritis-associated Interstitial Lung Disease (RA-ILD) progression and to define a combination of biomarkers, genetic and clinical variables capable of identifying patients at risk of RA-ILD progression


BERTHA is a multicentric, observational study that will enroll 100 RA-ILD patients to be followed for 2 years.

Interstitial Lung Disease (ILD) progression will be ascertained by quantitative image analysis and functional parameters. Variables associated with progression with be identified.

Additionally, RA-ILD endotypes will be investigated as well as their association with RA-ILD progression.
