The window of opportunity concept in RA shifted our focus to trying to treat disease earlier and more aggressively to improve long term outcomes. A natural development of this was to reconsider the possibility of therapeutic interventions aimed at the prevention of rheumatoid arthritis.

In clinical practice, pulmonary manifestations of rheumatic medical diseases such as rheumatoid arthritis (RA), psoriatic arthritis (PsA), and peripheral spondyloarthritis (pSpA) are typically not screened for upon diagnosis of a rheumatic disease in patients without any signs or symptoms suggestive of pulmonary involvement.

Since the millennium, we have seen an expansion in the number of advanced treatments both biologic and targeted synthetic disease modifying anti-rheumatic drugs for rheumatoid arthritis. The challenge remains on how best to characterise the subtypes of RA in order to choose the best drug to ensure optimal outcome for patients.
