What this Trial Is About
Researchers are collecting data to create a detailed observatory of microcrystalline rheumatism, including gout and calcium-crystal rheumatism, in patients treated at the Groupement des Hôpitaux de l'Institut Catholique de Lille. The goal is to better understand these conditions and improve patient care, particularly using medical imaging techniques. Patients already included in a previous observational study or new patients recruited during rheumatology consultations who meet the eligibility criteria may participate. Participants will have their sociodemographic and clinical information collected. Depending on usual care, they will receive ultrasound and/or dual-energy CT scans to evaluate microcrystalline deposits. Follow-up includes routine clinical consultations with ongoing collection of clinical, biological, and imaging data over time. Participants will be monitored through routine clinical visits where various assessments will be gathered, including diagnosis, body measurements, comorbidities, flare frequency and intensity, imaging data, and laboratory tests like uricemia and renal function. This data will be collected quarterly or semi-annually until the participant is lost to follow-up or ends participation. The study aims to link imaging findings with clinical evolution and comorbidities in microcrystalline rheumatism.
