Treatment of Pseudogout (Calcium Pyrophosphate Deposition Disease)
For acute pseudogout attacks, joint aspiration with intra-articular corticosteroid injection is the preferred first-line treatment, particularly in elderly patients or those with monoarticular/oligoarticular involvement, as it provides rapid symptom relief while avoiding systemic medication risks. 1, 2
Acute Attack Management
First-Line Options (Choose Based on Clinical Scenario)
Intra-articular corticosteroids:
- Joint aspiration combined with long-acting glucocorticosteroid injection is most effective for monoarticular or oligoarticular attacks 2
- Particularly safe in elderly patients who commonly have contraindications to NSAIDs 1
- Provides rapid symptom relief without systemic medication risks 1
Oral NSAIDs:
- Effective first-line agents when intra-articular injection is not feasible 2
- Dose similarly to acute gout attacks 2
- Critical caveat: Long-term use carries significant gastrointestinal, renal, and cardiovascular risks, especially in elderly patients who are the typical pseudogout demographic 2
Low-dose oral corticosteroids:
- Safe for short-term use and should be considered first-line in elderly patients with NSAID contraindications 1
- Prednisone is effective for patients who cannot tolerate NSAIDs or colchicine 2
Colchicine:
- Lower doses (0.5 mg up to three to four times daily, with or without 1 mg loading dose) minimize side effects while maintaining efficacy 2
- Critical pitfall: Avoid traditional high-dose regimens that cause severe gastrointestinal toxicity 2
- Contraindicated in severe renal impairment 2
- Must not be given with strong P-glycoprotein or CYP3A4 inhibitors (cyclosporin, clarithromycin) 2
Alternative Therapy for Refractory Cases
Intramuscular corticosteroids:
- Triamcinolone acetonide 60 mg IM is safe, well-tolerated, and effective 3
- Reasonable alternative when NSAIDs are contraindicated or for polyarticular attacks where intra-articular injections are impractical 3
- Major clinical improvement typically occurs by Day 3-4 3
- May require second injection on Day 1-2 in approximately 40% of patients 3
Adjuvant Measures
Prophylactic Treatment for Recurrent Attacks
For patients with frequent recurrent pseudogout attacks:
- Low-dose colchicine (0.5-1 mg daily) may be considered 1, 2
- Lower-dose NSAIDs can be used in patients who tolerate them well with history of recurrent attacks 2
- Key distinction from gout: There is no equivalent to urate-lowering therapy for pseudogout, as the disease involves calcium pyrophosphate crystals rather than uric acid 1, 2
Long-Term Management of Chronic CPPD
No standard long-term regimen exists for pseudogout 1, 4
Management focuses on:
- Treating underlying metabolic disorders (hyperparathyroidism, hemochromatosis, hypomagnesemia) when present 2
- For CPPD associated with osteoarthritis: employ standard OA management including physical therapy and appropriate exercise programs 2
- Weight loss if overweight or obese 2
- Analgesics for pain control as needed 2
Critical Management Considerations
Diuretic management:
- If patient is on diuretic therapy, consider stopping the diuretic if possible to reduce risk of pseudogout attacks 1
Address comorbidities:
- Hypertension, hyperlipidemia, and hyperglycemia should be managed as part of comprehensive care 1
