CTD-ILD is a lung disease caused by an autoimmune disease. CTD-ILD stands for Connective Tissue Related Interstitial Lung Disease. In an autoimmune disease, the immune system can attack the cells of the alveoli of the lung. As a result, the interstitium becomes inflamed and scarring can occur. We then speak of CTD-ILD.

Here the patient is given information about what an autoimmune disease is and what it does to the lungs. The patient is also given information about the causes, diagnosis and treatment of CTD-ILD.
