Did you know

Rheumatoid arthritis is an “autoimmune” disease
“Auto” means self and “immune” means protection against. Together this means that the immune system acts against the person’s own body.

Rheumatoid arthritis is a condition that affects about 1% of the population worldwide. Studies have observed that in people with rheumatoid arthritis, 10–20% also have interstitial lung disease (ILD).

There are many different conditions associated with pulmonary fibrosis. Some are referred to as ILDs. ILDs with pulmonary fibrosis are a challenging group of diseases that affect the interstitium of the lung (the space between the air sacs in the lung) and lead to the formation of scar tissue.

In someone with rheumatoid arthritis with ILD, the lungs become scarred, thickened and stiff. This makes it harder for oxygen to enter the blood and results in shortness of breath.

Rheumatoid arthritis with ILD can become progressive, which means that it might get worse over time. However, currently there is no way of predicting if, or how fast, this will happen. Some patients might not have changes in their symptoms, while other patients might experience a faster worsening of their symptoms. There are signs that can mean the disease has progressed, but your doctor, supported by a wider team of specialists, will work closely with you to monitor this.
