Scleroderma: when the skin and organs harden
An autoimmune disease producing too much collagen
Dr. Camille Roux
Internal medicine physician

In simple terms
Localised versus systemic forms, the early signs, and the treatments that changed the outlook.
What it is, in plain words
Scleroderma means hard skin. The immune system triggers fibroblasts to overproduce collagen, and small blood vessels narrow. In localised forms only patches of skin are affected. In systemic sclerosis, skin thickening is accompanied by damage to lungs, gut, kidneys and heart, which determines the prognosis.
Signs to look out for
- Raynaud's phenomenon, usually the first symptom, sometimes years ahead
- Puffy then tight, shiny skin of the fingers, later the face, limiting mouth opening
- Heartburn, difficulty swallowing, bloating and alternating bowel habit
- Breathlessness and dry cough from lung fibrosis or pulmonary hypertension
- Small red spots on the face and hands, fingertip ulcers and calcium deposits
Why it happens
The cause is unknown; it is more common in women aged 30 to 50. Certain occupational exposures such as silica are associated with a higher risk.
How doctors confirm it
Specific antibodies help classify the disease and predict complications. Nailfold capillaroscopy, lung function tests with diffusion capacity, high-resolution chest CT, echocardiography and regular blood pressure and kidney monitoring form the standard assessment.
Treatments and solutions
- Organ-directed treatment: proton pump inhibitors for reflux, calcium channel blockers and sildenafil for Raynaud's and ulcers
- Immunosuppression with mycophenolate, or tocilizumab, and antifibrotic nintedanib for progressive lung fibrosis
- ACE inhibitors urgently for scleroderma renal crisis, a treatment that transformed survival
- Specific pulmonary hypertension drugs when it is detected on screening
- Physiotherapy and hand exercises to preserve movement, plus stem cell transplant in selected rapidly progressive cases
Living with it day to day
Regular annual screening of lungs and heart is essential even when you feel well, because these complications are silent early and much more treatable when caught then.
When to seek medical help
Contact your specialist urgently for new high blood pressure with headache, a rapid rise in breathlessness, a non-healing fingertip ulcer, or difficulty swallowing solids.
