Sarcoidosis biomarkers, including serologic tests and genetic analyses, aid in disease management but lack specificity. Combining multiple biomarkers with clinical data improves diagnostic and prognostic accuracy for sarcoidosis.
Area of Science:
- Pulmonary Medicine
- Immunology
- Rheumatology
Background:
- Sarcoidosis diagnosis and management rely on various biomarkers.
- Biomarkers are evaluated for diagnosis, disease activity assessment, prognosis, and treatment response.
Purpose of the Study:
- To review the clinical and research utility of sarcoidosis biomarkers.
- To discuss the role of serologic tests, imaging, inflammatory cell identification, and genetic analyses.
Main Methods:
- Literature search of PubMed and Web of Science databases.
- Review of existing studies on sarcoidosis biomarkers.
Main Results:
- Most individual sarcoidosis biomarkers lack sufficient specificity and sensitivity for isolated clinical decisions.
- Biomarkers are most effective when integrated with comprehensive clinical data.
Conclusions:
- No single biomarker is adequate for sarcoidosis management.
- A multimodal approach combining biomarkers and clinical information is crucial for effective patient care.
