Inclusion Criteria: * Age between 40-70 years at screening * Proven hand OA by clinical examination and/or ultrasound 1. Clinical examination criteria: Heberden/Bouchards nodes and/or bony enlargement, squaring and/or deformity of the thumb base and no clinical signs of inflammatory arthritis (e.g. soft tissue swelling of two or less metacarpophalangeal (MCP) joints, and no soft tissue swelling of the wrist). 2. Ultrasound criteria: Osteophytes in the interphalangeal joints and/or the thumb base, and no signs of inflammatory arthritis (e.g. synovitis with power Doppler activity in two or less MCP joints and no synovitis with power Doppler activity in the wrist). * Capable of understanding and signing an informed consent form * Provided a written informed consent to participate in the study Exclusion Criteria: * Diagnosis of inflammatory arthritic disease, e.g. seropositive or seronegative rheumatoid arthritis, psoriatic arthritis, reactive arthritis, spondyloarthritis or arthritis related to connective tissue disorders * Diagnosis of psoriasis * Erythrocyte sedimentation rate (ESR) \> 40 mm/hour and/or C-reactive protein (CRP) \>20 mg/L, without a known ongoing infection * Anti Cyclic Citrullinated Protein (anti-CCP) and/or rheumatoid factor positivity * Ferritin \>200 microgram/L for women and \>300 microgram/L for men and s-iron/s-total iron binding capacity (TIBC) above 50% * Major co-morbidities (e.g. severe malignancies, severe diabetes mellitus, severe infections, uncontrollable hypertension, severe cardiovascular disease or severe respiratory disease) * Mental or psychiatric disorders, alcohol or drug abuse, language difficulties or other factors that make compliance to the study protocol difficult.
