How do you approach using DMARDs for patients with CPP arthritis who have frequent flares?

As far as I know, none of these agents are proven to prevent CPPD flares. Colchicine for acute flares. If someone is aware of evidence that any of these other choices work, I would be glad to hear about them. I have a patient with Gittleman's syndrome who had severe CPPD with almost constant flares....
