Diagnostic Rentability of Screening for Associated Conditions in Calcium Pyrophosphate Deposition Disease Patients
The purpose of this study is to determine whether thorough analytical evaluation is useful to diagnose metabolic conditions associated to calcium pyrophosphate deposition disease.
|Study Design:||Observational Model: Case Control
Time Perspective: Longitudinal
|Official Title:||Appraisal of the Diagnostic Rentability of Thorough Analytical Screening Searching Associated Conditions in Patients Newly Diagnosed With Calcium Pyrophosphate Dihydrate Deposition Disease|
|Study Start Date:||January 1997|
|Study Completion Date:||December 2006|
The diagnostic usefulness of screening for hyperparathyroidism, hemochromatosis, hypothyroidism and hypophosphatasia in patients diagnosed with calcium pyrophosphate dihydrate (CPPD) deposition disease is uncertain.
Patients diagnosed with CPPD deposition disease were compared to patients with rheumatoid arthritis and psoriatic arthritis over a 9-year period. All patients were prospectively followed for at least 12 months. Serum calcium, phosphorus, alkaline phosphatase, thyroid-stimulating hormone, ferritin, iron, and total iron binding capacity were determined in all patients.
