SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis) syndrome is a rare inflammatory bone disease that affects one in ten thousand individuals with peak onset between 20-50 years old. Currently there is no diagnostic test or approved treatment for these patients and although the disease is not life threatening, it significantly affects quality-of-life for both the patient and their family.
SAPHO may be linked to another disease referred to as CNO or CRMO (chronic non-bacterial osteomyelitis / chronic recurrent multifocal osteomyelitis) that affects children and young adults. Both conditions have variable onsets and clinical features which makes studying them challenging.
In this specific study, patients with SAPHO/CRMO/CNO, who are already recruited into the SAPHO: Synovitis, Acne, Pustulosis, Hyperostosis & Osteitis Syndrome (SAP) BioResource cohort, will be asked to give an additional blood sample allowing us to analyse the genetic code in a number of different types of immune cells that may be involved in causing the disease. We hope that this will shed light on the possible cause of these conditions and therefore help to improve treatments.
