About this study
Official title: Appraisal of the Diagnostic Rentability of Thorough Analytical Screening Searching Associated Conditions in Patients Newly Diagnosed With Calcium Pyrophosphate Dihydrate Deposition Disease
The purpose of this study is to determine whether thorough analytical evaluation is useful to diagnose metabolic conditions associated to calcium pyrophosphate deposition disease.
Read the detailed description
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Chondrocalcinosis, run by Sociedade Galega de Reumatoloxía at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Mar 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Mar 2007.
