Haemochromatosis arthritis is a common but often under-recognised complication of haemochromatosis — a genetic condition where the body absorbs and stores too much iron. Excess iron is deposited in organs such as the liver, pancreas, heart, joints, and tendons, causing long-term damage. When it builds up in joint and tendon tissue, it causes haemochromatosis-related joint pain that can mimic other types of arthritis, such as osteoarthritis or rheumatoid arthritis.
Symptoms of haemochromatosis arthritis
The commonest symptom is joint pain and stiffness, usually affecting the hands, particularly the second and third metacarpophalangeal (MCP) joints. Patients often notice morning stiffness, which can resemble inflammatory arthritis, though it usually lasts a shorter time. The joints can swell and become tender, and movement gradually becomes restricted as the condition progresses. A characteristic sign is the “iron fist salute” — when clenching the fist, the index and middle finger joints can’t fully bend. Other joints, including the knees, hips, ankles, and shoulders, may become painful over time, and many patients describe chronic joint pain that affects their quality of life.
Beyond the joints, haemochromatosis commonly causes tiredness, disturbed sleep, and reduced libido. But joint pain is the commonest symptom at diagnosis, present in about 45% of patients.
Unlike osteoarthritis, haemochromatosis arthritis often affects younger people and tends to involve non-weight-bearing joints such as the fingers. Other musculoskeletal features include:
- Calcium deposition in joints, also known as pseudogout
- Achilles tendonitis or plantar fasciitis
- Reduced bone mineral density
How is haemochromatosis arthritis assessed?
A careful clinical assessment helps distinguish haemochromatosis arthritis from other joint conditions. The history should explore any family history of haemochromatosis and complications such as liver disease, diabetes, or heart problems — all linked to iron overload.
The arthritis often begins earlier than expected and in unusual joints. The MCP and PIP joints of the hand may be swollen or enlarged, with impaired hand function, and the hips, knees, and shoulders may also be involved. In advanced cases, there may be systemic signs of haemochromatosis such as bronzed skin, an enlarged liver, or diabetes.
Investigations
Investigations confirm haemochromatosis and rule out other causes of arthritis.
Blood tests
- Raised ferritin, usually above 1000
- Transferrin saturation is often greater than 45%
- Liver function tests may be abnormal
- Genetic testing for HFE mutations (C282Y, H63D) confirms the diagnosis
In early cases, ferritin or transferrin saturation may be only slightly elevated or even normal, so any clinical suspicion should prompt genetic testing. (These iron studies are often picked up as part of a rheumatoid/arthritis panel test when investigating joint swelling.)
Joint imaging
- X-rays may show joint space narrowing, osteophytes, and calcium deposits in cartilage (chondrocalcinosis); hook-like bony spurs are characteristic of haemochromatosis arthritis.
- MRI detects cartilage and soft-tissue changes earlier
Other tests
- Liver ultrasound or MRI assesses iron overload
- A Fibroscan can assess for liver fibrosis or cirrhosis
Treatment of haemochromatosis arthritis
Management aims to control the systemic iron overload and relieve the joint symptoms.
Iron reduction therapy. Regular venesection (removal of blood) is the mainstay for lowering ferritin, with iron chelation as an option for those who can’t have venesection. Importantly, venesection doesn’t reverse the arthritis, but it does prevent the other complications of iron overload from progressing.
Arthritis management. Pain can be eased with paracetamol or NSAIDs where appropriate, and corticosteroid injections may help during flares. Physiotherapy maintains mobility, occupational therapy supports hand function, and joint replacement may be needed in severe cases.
Lifestyle. Avoid excess alcohol to reduce strain on the liver, keep to a healthy weight, and stay active within your limits.
Frequently asked questions about haemochromatosis and joint pain
Does treating the iron overload cure the arthritis?
No. Venesection lowers ferritin and prevents other iron-overload complications, but it doesn’t reverse established joint damage — the joint pain often persists despite good iron control. That’s why treatment combines iron reduction with targeted arthritis management.
Which joints does haemochromatosis arthritis affect?
Most characteristically, the second and third knuckle joints (MCP joints) of the hand — an unusual pattern that’s a useful clue. The wrists, knees, hips, ankles, and shoulders can also be involved.
How is it told apart from rheumatoid arthritis?
Both can cause hand joint pain and morning stiffness. Still, haemochromatosis arthritis tends to affect the MCP joints, with shorter-lived stiffness, often starts at a younger age, and comes with other clues (family history, fatigue, raised ferritin and transferrin saturation, sometimes bronzed skin or diabetes). Iron studies and genetic testing make the distinction.
Can I still exercise with haemochromatosis arthritis?
Yes — staying active within your limits is encouraged, alongside physiotherapy to maintain joint mobility and hand function. Activity should be balanced against joint symptoms.
Should my family be tested?
Because haemochromatosis is genetic, first-degree relatives are often advised to have iron studies and genetic testing — discuss this with your doctor.
Final word from Sport Doctor London about haemochromatosis and joint pain
Haemochromatosis arthritis often affects the knuckle joints of the hand and can be mistaken for osteoarthritis or rheumatoid arthritis. Its other musculoskeletal features include pseudogout, Achilles tendonitis, plantar fasciitis, carpal tunnel syndrome, and reduced bone density. Early recognition matters because venesection can prevent the other complications of iron overload, even though the joint pain often persists. Most patients need a combination of systemic treatment and targeted arthritis management.
