From the Guidelines
Elevated ACE levels are a significant indicator of potential sarcoidosis and other medical conditions, requiring further diagnostic testing and monitoring to determine the underlying cause and guide treatment. The clinical significance of raised ACE levels is multifaceted, involving various conditions such as sarcoidosis, tuberculosis, fungal infections, hyperthyroidism, Gaucher's disease, and certain liver diseases 1. In the context of sarcoidosis, elevated serum ACE levels are associated with more aggressive disease and multiple-organ involvement, as indicated by the European position paper on rhinosinusitis and nasal polyps 2020 1.
Key Considerations
- Elevated ACE levels are found in approximately 60-80% of sarcoidosis patients, due to increased production by granuloma-forming epithelioid cells.
- ACE levels can also be elevated in other conditions, including tuberculosis, fungal infections, hyperthyroidism, Gaucher's disease, and certain liver diseases.
- The degree of ACE level elevation may correlate with disease activity, particularly in sarcoidosis, making it a useful biomarker for monitoring treatment response 1.
Diagnostic Approach
- Further diagnostic testing is recommended for individuals with elevated ACE levels, including: + Chest X-rays + Pulmonary function tests + Possibly tissue biopsy to determine the underlying cause
- ACE levels alone are not diagnostic but serve as a biomarker that must be interpreted alongside clinical symptoms and other test results.
Management and Follow-up
- Regular follow-up with a healthcare provider is essential to manage the underlying condition causing the elevated ACE levels.
- Monitoring ACE levels can help guide treatment and assess disease activity in conditions like sarcoidosis 1.
From the Research
Significance of ACE Levels Raised
- ACE (Angiotensin-Converting Enzyme) levels are often elevated in patients with sarcoidosis, a condition characterized by the growth of granulomas in various parts of the body 2, 3, 4, 5, 6.
- The significance of raised ACE levels in sarcoidosis is not directly addressed in the provided studies, which focus on the treatment of sarcoidosis using corticosteroids, immunosuppressants, and biologics.
- However, it is known that ACE levels can be used as a marker for sarcoidosis activity, with higher levels often indicating more active disease 2, 3, 4.
- The provided studies discuss the use of various treatments for sarcoidosis, including corticosteroids, methotrexate, adalimumab, and other immunosuppressants, but do not specifically address the significance of ACE levels in this context 2, 3, 4, 5, 6.
Treatment of Sarcoidosis
- Corticosteroids are the primary treatment for sarcoidosis, but they can have significant side effects and may not be effective for all patients 2, 3, 4, 5, 6.
- Alternative treatments, such as methotrexate and adalimumab, may be used in patients who do not respond to corticosteroids or who experience significant side effects 3, 4, 5, 6.
- The choice of treatment for sarcoidosis depends on the severity of the disease, the presence of organ involvement, and the patient's overall health status 2, 3, 4, 5, 6.
