Registered outcomes1

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryATP Levels in Synovial Fluid5 days
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.

Outcomes1

Each outcome the trial posted results for, in ClinicalTrials.gov's words.

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYATP Levels in Synovial Fluid5 days
Two subjects ( one in probenecid and one in no intervention group) had no measurable ATP on the second aspirate, and one subject in the no intervention group did not have any synovial fluid on the second visit.
