More than 15 percent of patients with rheumatoid arthritis (RA) develop interstitial lung disease within 20 years, associated with shorter survival, according to data published in Arthritis Care & Research recently. According to the authors,  patients with RA commonly experience fatigue and arthralgias; consequently, they are less active than healthy adults. As a result, studies have reported that a large proportion (up to 90%) of patients with radiologic evidence of RA-associated interstitial lung disease (RA-ILD) do not report respiratory symptoms.
