ClinConnect Summary

The CRYSTALILLE Cohort trial is focused on understanding and improving the treatment of certain types of arthritis caused by crystal deposits in the joints, specifically gout and other related conditions. Researchers aim to gather information from patients at the Groupement des Hôpitaux de l'Institut Catholique de Lille to create a detailed picture of these diseases. This study will use medical imaging techniques to help doctors better diagnose and manage these conditions.

To participate in this trial, you should be between 65 and 74 years old and have been diagnosed with gout, calcium pyrophosphate crystal disease, or hydroxyapatite crystal rheumatism. You should also be someone who has had or will benefit from an ultrasound or special type of scan to check for crystal deposits. If you join, you can expect to undergo imaging tests and provide some health information that will help researchers learn more about these conditions. It's important to know that if you have any reservations about participating or if you're unable to undergo the necessary imaging, you may not be eligible for this study.
