About the Calcium pyrophosphate deposition (CPPD) Working Group

Calcium pyrophosphate deposition (CPPD) is due to calcium crystals depositing within joints. CPPD can lead to different forms of arthritis including an acute form (commonly known as pseudogout), where people experience acute episodes of joint pain and swelling, or a chronic form, where symptoms can last for a longer period. People with osteoarthritis can also develop CPPD. Not all people with calcium crystals in their joints experience symptoms.

Although CPPD is common, there has been very little research into this condition. Currently, there is no universally accepted way of reporting outcomes in studies of this condition.

CPPD Delphi Studies

The OMERACT CPPD Working Group is working on a Delphi survey on what should be measured in long-term studies of CPPD (e.g. studies to treat chronic joint inflammation), and the second focused on what should be measured in short-term studies of CPPD (e.g. studies to treat an acute flare).

We would gladly welcome your participation!  The goal is to identify what features should be measured in future clinical trials of treatments for CPPD.

As is customary with OMERACT we are asking rheumatologists, other health professionals, researchers, and patients around the world to complete the surveys (only takes 10 minutes). We would greatly appreciate it if you could help us by completing the survey so we can have as many opinions and preferences as possible from healthcare providers and patients. I

You are of course under no obligation to complete the survey. The results are anonymous and we will not have access to any individual data or responses, only aggregated data.

Please, follow the link below to register and complete the survey
