CPPD disease cohort study
The University of Auckland is conducting a study for people with calcium pyrophosphate deposition (CPPD) disease. The study is looking at how people with CPPD disease are affected by the condition, in particular their symptoms, disease activity patterns and perceptions of the illness. The study is also investigating the imaging features of CPPD.
What's involved?
Study participants will attend two visits at the University of Auckland’s Clinical Research Centre, spaced six months apart. At each visit, they will be assessed by a rheumatologist and complete questionnaires. They will also have imaging of their wrists and knees (by ultrasound and X-ray) and have blood tests taken.
Participants will receive a $50 supermarket voucher after each visit. Between visits, they will be asked to keep a diary to record flares of arthritis related to CPPD disease.
