Brief Summary
Today, regular X-ray examination is not sufficiently sensitive for detecting progression of bone destruction in rheumatoid arthritis, but a new type of high-resolution CT scanner, the High-Resolution peripheral Quantitative Computed Tomography (HR-pQCT) can detect very early and minor joint injuries. The purpose of this study is to use HR-pQCT techniques to look at the damage and disease activity progression in the hand and wrist joints of patients with rheumatoid arthritis.

Study Arms (3)
Rheumatoid arthritis
Patients with Rheumatoid arthritis ≥5 years according to the ACR/EULAR 2010 classification criteria or the American Rheumatism Association 1987 revised criteria. ICD-10: M059 Seropositive rheumatoid arthritis UNS, M060 Seronegative rheumatoid arthritis, M069 Rheumatoid arthritis UNS.
Pre-Rheumatoid arthritis
Patients with joint pain, but no swelling and Anti-CCP 3 times above the upper limit.
Healthy Subjects
Healthy age- and sex-matched Individuals are recruited, as a control group.
Eligibility Criteria
Rheumatoid arthritis patients and pre-rheumatoid patients are recruited from the outpatient clinic at the Department of Rheumatology, Aarhus University Hospital. Healthy age- and sex-matched Individuals are recruited, as a control group, by posting at libraries in Aarhus, Aarhus University, Aarhus University Hospital and postings on the websites www.forsøgsperson.dk and www.Sundhed.dk.
You may qualify if:
- Patients (\> 18 years) with rheumatoid arthritis ≥5 years according to the ACR/EULAR (2010) classification criteria or American Rheumatism Association 1987 revised criteria for the patients who were diagnosed before 2010.
- Patients who are receiving treatment on an outpatient basis.
- Ability and willingness to give written informed consent and to meet the requirements of the trial protocol.
You may not qualify if:
- Patients who have previously suffered trauma in the form of fracture or luxation of the hand are excluded.
- Evidence of active malignant disease.
- Hypo- or hyperthyroidism.
- Hypocalcaemia.
- Impaired renal function (eGFR \<35ml/min).
- Age over 18 years.
- Anti-CCP 3 times the upper limit of the reference interval.
- Arthralgia.
- Ability and willingness to give written informed consent and to meet the requirements of the trial protocol.
- Pregnancy.
- Swelling of joints. Verified by clinical ultrasound.
- Patients who have previously suffered trauma in the form of fracture or luxation of the hand are excluded.
- Evidence of malignant disease.
- Hypo- or hyperthyroidism.
- Age over 18 years.
- +10 more criteria
