Insights
French experts established 31 consensus recommendations for managing giant cell arteritis (GCA), also known as Horton's disease. These guidelines aim to standardize GCA care, addressing diagnosis, treatment, and relapse management.
Area of Science:
- Rheumatology
- Vasculitis Research
Background:
- Giant cell arteritis (GCA), or Horton's disease, presents management challenges due to existing uncertainties.
- Standardized approaches are needed to optimize patient outcomes in GCA.
Purpose of the Study:
- To develop comprehensive French national recommendations for the management of GCA.
- To address uncertainties and harmonize GCA treatment standards across France.
Main Methods:
- A multidisciplinary panel of 33 physicians from the French Study Group for Large Vessel Vasculitis (GEFA) developed the recommendations.
- An iterative consensus-seeking process, literature review, and a 5-point Likert scale evaluation were employed.
- Recommendations required ≥ 80% agreement among panel members for approval.
Main Results:
- 31 consensus recommendations were established, covering 15 key topics in GCA management.
- Recommendations address GCA nomenclature, classification, diagnostic tools (biopsy, imaging), and management of aorta involvement.
- Guidance is provided on glucocorticoid regimens, complicated GCA treatment, use of immunosuppressants and biologics, and relapse management.
Conclusions:
- The developed recommendations provide a standardized framework for GCA management in France.
- These guidelines are intended to reduce uncertainties and harmonize clinical practice for GCA patients.
- Regular updates are planned to ensure the recommendations remain current with evolving GCA research.
Purpose:
Management of giant cell arteritis (GCA, Horton's disease) involves many uncertainties. This work was undertaken to establish French recommendations for GCA management.
Methods:
Recommendations were developed by a multidisciplinary panel of 33 physicians, members of the French Study Group for Large Vessel Vasculitis (Groupe d'étude français des artérites des gros vaisseaux [GEFA]). The topics to be addressed, selected from proposals by group members, were assigned to subgroups to summarize the available literature and draft recommendations. Following an iterative consensus-seeking process that yielded consensus recommendations, the degree of agreement among panel members was evaluated with a 5-point Likert scale. A recommendation was approved when ≥ 80% of the voters agreed or strongly agreed.
Results:
The 15 retained topics resulted in 31 consensus recommendations focusing on GCA nomenclature and classification, the role of temporal artery biopsy and medical imaging in the diagnosis, indications and search modalities for involvement of the aorta and its branches, the glucocorticoid regimen to prescribe, treatment of complicated GCA, indications for use of immunosuppressants or targeted biologic therapies, adjunctive treatment measures, and management of relapse and recurrence.
Conclusions:
The recommendations, which will be updated regularly, are intended to guide and harmonize the standards of GCA management.
