Treatment of Calcium Pyrophosphate Deposition Disease in Chronic CPP Crystal Inflammatory Arthritis

Calcium pyrophosphate deposition (CPPD) disease can present not only as acute attacks but also as a persistent, chronic inflammatory arthropathy. This page covers the treatment approach for patients in whom chronic CPP crystal inflammatory arthritis is the predominant clinical picture.

Clinical Scenario

Chronic CPP crystal arthritis is a chronic inflammatory oligoarthritis or polyarthritis driven by ongoing CPP crystal deposition. In some patients, the pattern of persistent joint inflammation can be mistaken for rheumatoid arthritis, making accurate recognition of this subset important for appropriate management.

Treatment Approach

Prolonged anti-inflammatory therapy forms the basis of management in this chronic form. This includes low-dose options from more than one drug class — the full selection of agents, sequencing, and any individualised adjustments are detailed in the complete protocol.

References

A subset of patients with CPP arthritis may present with symptoms of chronic joint inflammation that can be mistaken for RA.

Chronic CPP crystal arthritis, on the other hand, is a chronic inflammatory oligoarthritis or polyarthritis.

In such cases, prolonged administration of the lowest possible dose of NSAID may be effective in controlling symptoms.

Alternative therapeutic options include using colchicine (0.5 or 0.6 mg twice daily) for 8–12 weeks or low-dose oral glucocorticoids, such as prednisone, in doses not exceeding 7.5–10 mg daily.
