Giant cell arteritis in Mumbai.
OBJECTIVE
To study the clinical profile of patients with giant cell arteritis in Mumbai.


METHODS
From our database, patients with a diagnosis of giant cell arteritis (GCA) over a fifteen year period (January 1990 to December 2005) were included. Clinical manifestations, temporal artery biopsy, treatment, and follow-up data of these patients were analyzed.


RESULTS
Twenty one patients with GCA were identified. However, data were available only for 16 patients. The median age was 66.5 years (58-78 yrs) with male to female ratio of 1:1. The mean time from symptom onset to diagnosis was 5.18 months (0.5-24 months). Clinical manifestations included new onset headache (15), fever (9), weight loss (9), jaw claudication (9), polymyalgia rheumatica (5), visual disturbances (3), scalp nodule (1), temporal artery tenderness (11), tortuosity (9), and scalp tenderness (6). ESR was elevated in 15 patients with a median of 106.5 mm at 1 hr (25-135 mm/hr). Temporal artery biopsy was done in 11 patients and confirmed the diagnosis in 10 patients. Color doppler study of the temporal arteries (9 patients) revealed halo sign (indicating arterial wall edema) in 6 patients. Biopsy as per site by color doppler study was performed in 6 of these patients and was positive in 5. All patients had a good initial response to steroids, however, on follow up, 3 patients required addition of methotrexate. At a median follow up (n = 14) of 6 months (range 6-156), steroids were successfully stopped in 7 patients at 1 to 3 years interval. The disease relapsed in 1 patient. Of the remaining 7 patients, 2 were steroid dependent and 5 patients were doing well on low dose prednisolone.


CONCLUSIONS
GCA, though uncommon in India, should be suspected in all elderly patients with a new onset headache, fever, jaw claudication, or high ESR. Color doppler sonography is a useful noninvasive method for the diagnosis of GCA and also helps to identify the site to biopsy. Most respond to steroid therapy while some need addition of steroid sparing agents.
