Pericarditis is swelling of the sac that surrounds the heart, the pericardium, causing chest pain. For most patients, the condition improves with simple anti-inflammatory medications like colchicine and ibuprofen. However, in 20-30% of patients the condition comes back. Diagnosis of recurrent pericarditis is frequently missed or delayed, and many patients require prolonged courses of corticosteroids to control their disease. Together these factors damage the quality of life of patients with recurrent pericarditis. Currently there is limited understanding of why pericarditis comes back in some patients, and how best to treat it when it does. PAIReD (Pericarditis: Auto-Inflammation in Recurrent Disease) is an observational research study funded by the British Heart Foundation that will investigate the role inflammation plays in recurrent pericarditis. Patients with recurrent pericarditis and other auto-inflammatory diseases will be recruited from the specialist fever clinic at the Royal Free Hospital, where they will be asked to donate blood up to six times over a three year period. Healthy participants will be recruited at the Royal Free Hospital or Guy's Hospital. Relatives of participants with recurrent pericarditis will be recruited at the Royal Free Hospital. They latter two groups will attend one appointment where blood or saliva samples will be taken. A subset of participants will also provide fingerstick blood samples and questionnaires from home, for up to one year. Clinical data will be collected prospectively and by retrospective case note review. Blood from participants will be analysed to look at how the immune cells of patients with recurrent pericarditis function during the course of their disease, and to look for genetic changes in patients with recurrent pericarditis that might contribute to their condition. Together this knowledge has to potential to help clinicians diagnose and monitor patients with recurrent pericarditis more accurately, and researchers to design more effective treatments.
