[Management of patients with a suspicion of giant cell arteritis: Survey among general practitioners and specialists]

Abstract

Introduction: Headache, visual disturbances and shoulder and hip girdle pain are frequent symptoms of consultation and the diagnosis of giant cell arteritis (GCA) can be evoked in these situations. However, GCA is a rare disease, and the management modalities of a clinical suspicion of GCA are poorly described, which warranted this study.

Methods: This is a survey evaluating the management of a suspected case of GCA. The questionnaires were sent to general practitioners (GPs), members of the French Rheumatology Society (SFR) and the French National Society of Internal Medicine (SNFMI) RESULTS: One thousand four hundred and fifty two physicians responded to the survey, including 967 GPs (66.6 %) and 485 other specialists (33.4 %). GPs immediately referred the patient to the emergency room in 42 % of cases, and to a specialist colleague in 72 % of cases in the presence of visual symptoms. GPs and other specialists reported performing temporal artery biopsy (TAB) respectively in 46.7 % and 69.7 % of cases (P<0.05). GPs and other specialists reported using diagnostic imaging in 7.4 % and 16.2 % of cases, respectively (P<0.05). Temporal artery ultrasound was the most used diagnostic imaging. The average prednisone equivalent dose prescribed as initial treatment was 1mg/kg/day for GPs and 0.7mg/kg/day for other specialists (P<0.05).

Conclusion: Some suspected GCA patients would be managed by their GPs. Imaging was little used for the diagnosis of GCA and TAB remained the preferred diagnostic examination. The initial prednisone equivalent dose varied between GP and other specialists.
