Rheumatoid arthritis can cause interstitial lung lesions that result in interstitial lung fibrosis. In addition to joint swelling and pain, rheumatoid arthritis can also cause lung lesions that induce interstitial lung fibrosis. Advanced age, male gender, smoking history, high titers of rheumatoid factor and anti-CCP levels have been found to be risk factors for rheumatoid arthritis induced interstitial fibrosis in the lungs. Patients may experience progressive shortness of breath, fatigue, and dry cough as the lung disease progresses. Later stages of the disease mainly affect lung function, and patients may experience recurrent shortness of breath, breath-holding and even induced infections. Interstitial lung fibrosis is a common and serious complication of rheumatoid arthritis and should be treated actively.
