Study Summary

This study will investigate the hypothesis that probenecid, a medication currently used for gout, reduces levels of ATP in the joint fluid of patients with calcium pyrophosphate deposition disease (CPPD), another common type of crystal-related arthritis. There is good evidence that CPPD results from an excess of ATP in joints. The investigators will measure levels of ATP in joint fluid before and after 5 days of treatment with probenecid. This study will serve to rationalize larger studies of probenecid in CPPD.

Primary Outcome

The investigators will measure levels of ATP in synovial fluid from patients with CPPD before and after treatment with probenecid compared to patients receiving no therapy. ATP levels are measured with a standard bioluminescent assay.
