Reynolds syndrome is a rare autoimmune disease that affects the connective tissues in the body. It is mainly recognised as an overlap condition involving features of primary biliary cholangitis and systemic sclerosis (scleroderma).

The condition can affect the skin, blood vessels, liver and other internal organs. Symptoms and severity can vary from person to person, and long-term medical care may be needed to manage complications and protect organ function.

What Are the Types of Reynolds Syndrome?

Reynolds syndrome is an overlap condition rather than a disease with clearly defined separate types. However, affected individuals may have different patterns of autoimmune disease depending on the conditions and organ systems involved.

Primary Biliary Cholangitis (PBC): An autoimmune liver disease that damages the small bile ducts and may eventually cause liver scarring.
Limited Cutaneous Systemic Sclerosis: Mainly causes skin thickening of the fingers, hands and face and is often associated with Raynaud's phenomenon.
Diffuse Cutaneous Systemic Sclerosis: Causes more widespread skin thickening and may affect internal organs.
Sjögren's Syndrome Features: Some individuals may develop dry eyes and dry mouth due to autoimmune damage to moisture-producing glands.
Mixed Connective Tissue Disease Features: Symptoms may overlap with conditions such as lupus, scleroderma and polymyositis.

What Are the Symptoms of Reynolds Syndrome?

Reynolds syndrome can cause symptoms involving the skin, blood vessels, joints, digestive system and liver. The symptoms depend on the severity of the autoimmune disease and the organs affected.

Raynaud's phenomenon
Skin thickening or tightening
Skin ulcers, especially on the fingers
Joint pain
Swelling of the hands and feet
Changes in the skin of the fingers and toes
Difficulty swallowing
Heartburn
Diarrhea
Fatigue
Unexplained weight loss

What Are the Symptoms of Reynolds Syndrome in Women?

Reynolds syndrome is more commonly reported in women. Symptoms may reflect features of systemic sclerosis and autoimmune liver disease and can vary depending on the organs involved.

Skin thickening: Tight or shiny skin, particularly around the fingers, hands and face.
Raynaud's phenomenon: Reduced blood flow that causes the fingers or toes to turn white, blue or red in response to cold or stress.
Dry eyes and mouth: Reduced tear and saliva production may cause discomfort and difficulty swallowing.
Joint pain and swelling: Pain or stiffness may affect the hands, feet and other joints.
Digestive problems: Difficulty swallowing, acid reflux or heartburn may occur.
Fatigue: Persistent tiredness can interfere with daily activities.
Liver problems: Autoimmune damage to the bile ducts may gradually affect liver function.
Lung or kidney involvement: Some individuals may develop shortness of breath, cough or kidney problems.

What Causes Reynolds Syndrome?

The exact cause of Reynolds syndrome is not fully understood. It is believed to develop when the immune system mistakenly attacks healthy tissues, particularly the connective tissues and bile ducts.

A combination of genetic susceptibility, abnormal immune system activity and environmental triggers may contribute to the condition.

Connective tissue diseases: Autoimmune connective tissue disorders are closely associated with the syndrome.
Autoimmune dysfunction: Abnormal immune activity may damage healthy tissues and organs.
Genetic factors: Certain inherited characteristics may increase susceptibility to autoimmune diseases.
Infections: Some infections may act as environmental triggers in genetically susceptible individuals.
Environmental factors: Exposure to certain substances may contribute to abnormal immune responses.

When to See a Doctor for Reynolds Syndrome?

Medical evaluation is important if symptoms suggest an autoimmune connective tissue or liver disorder. Early assessment can help identify organ involvement, begin appropriate treatment and reduce the risk of complications affecting the liver, lungs, heart or blood vessels.

You should see a doctor if you have:

Persistent colour changes, numbness or pain in the fingers and toes
Progressive skin tightening, joint pain or difficulty swallowing
Ongoing fatigue, itching, dry eyes, dry mouth or unexplained weight loss

Get medical help immediately if:

You develop severe shortness of breath or chest pain
You notice yellowing of the skin or eyes with severe weakness
You develop sudden kidney problems, severe headache or very high blood pressure

These could be signs of a serious complication of Reynolds syndrome, which needs urgent care.

Reynolds syndrome is usually treated by a rheumatologist and a hepatologist or gastroenterologist. Depending on the organs affected, care may also involve a dermatologist, pulmonologist, cardiologist, nephrologist and other specialists.

How Is Reynolds Syndrome Diagnosed?

Reynolds syndrome is diagnosed using a combination of medical history, physical examination, blood tests and other investigations. Doctors look for features of systemic sclerosis together with evidence of autoimmune liver disease.

Medical History and Physical Examination

The doctor asks about symptoms such as Raynaud's phenomenon, skin tightening, joint problems, fatigue, itching and digestive symptoms. The skin, joints and signs of liver involvement are also examined.

Blood Tests

Blood tests may be performed to check liver function and identify antibodies associated with autoimmune diseases.

Antinuclear antibody (ANA) testing
Antimitochondrial antibody (AMA) testing
Anticentromere antibody testing
Liver function tests
Inflammatory marker tests

Imaging Tests

Ultrasound, MRI or CT scans may be used to evaluate the liver and other internal organs when complications are suspected.

Liver Assessment

Additional tests may be required to assess liver damage and determine the severity of primary biliary cholangitis.

Heart and Lung Tests

An electrocardiogram, echocardiogram and lung function tests may be performed to check for heart or lung involvement.

Skin Biopsy

In selected cases, a skin biopsy may help evaluate tissue changes and support the diagnosis.

How Is Reynolds Syndrome Treated?

There is no single cure for Reynolds syndrome. Treatment focuses on controlling autoimmune activity, managing symptoms, protecting affected organs and treating the individual conditions that make up the syndrome.

Medications for Autoimmune Symptoms

Immunomodulatory therapy: Medicines may be used to regulate abnormal immune system activity and reduce inflammation.
Corticosteroids: These may be prescribed carefully in selected cases to control inflammation.
Other immunosuppressive medicines: Treatment may be considered when the lungs, skin or other organs are significantly affected.

Treatment for Raynaud's Phenomenon

Vasodilators: These medicines widen blood vessels and improve blood flow.
Calcium channel blockers: These can reduce episodes of Raynaud's phenomenon and improve circulation to the fingers and toes.

Treatment for Liver Disease

Medicines may be prescribed to slow the progression of primary biliary cholangitis and protect liver function. Regular liver monitoring is an important part of long-term care.

Physical Therapy

Exercises and rehabilitation techniques can help maintain joint mobility, muscle strength and physical function.

Lifestyle and Supportive Care

Avoid smoking and exposure to extreme cold.
Protect the hands and feet from temperature changes.
Attend regular medical follow-up appointments.
Follow treatment recommendations for liver, skin, digestive and vascular symptoms.
Report new breathing, heart, kidney or liver symptoms promptly.

What Are the Risk Factors for Reynolds Syndrome?

Because Reynolds syndrome is rare, its exact risk factors are not completely understood. Factors associated with autoimmune and connective tissue diseases may increase the likelihood of developing the condition.

Female sex
Family history of autoimmune diseases
Existing systemic sclerosis or scleroderma
Primary biliary cholangitis
Other connective tissue diseases
Genetic susceptibility
Exposure to certain environmental triggers
