ComplicationsBy Mayo Clinic staff
Mixed connective tissue disease can lead to serious complications, including:
- Lung problems. High blood pressure affecting the arteries in your lungs (pulmonary hypertension) is the most common cause of death in people with mixed connective tissue disease.
- Heart disease. Mixed connective tissue disease sometimes results in the enlargement of parts of the heart and inflammation around the heart.
- Kidney failure. The kidney damage caused by mixed connective tissue disease can progress for years without producing any signs or symptoms, but it can eventually result in kidney failure.
Treatment side effects
Corticosteroids are commonly used to manage the signs and symptoms of mixed connective tissue disease. These medications are effective, but they carry risks. If you take corticosteroids, your doctor will likely monitor you for adverse effects, such as osteoporosis, muscle weakness and infection.
