This study looks at people with a lung condition called Idiopathic Interstitial Pneumopathy (IIP), which affects breathing. Researchers will observe both children and adults to learn more about how this condition develops over time. If you or your child has symptoms like difficulty breathing (dyspnea), fast breathing (tachypnea), coughing, or blue lips or skin (cyanosis), you may qualify. Chest scans showing specific patterns and lung tests indicating breathing issues are also part of the criteria.

Key Points:

• The study involves long-term follow-up visits to monitor your or your child's condition over time.
• Participants must have a form of IIP not caused by drugs, immune problems, or certain diseases.
• You must be able to provide consent and be part of the French National Health Insurance system.

This study is observational, meaning researchers will gather information but not provide any treatment. If you're interested, it's important to discuss with your doctor to see if this study fits your situation.
