Giant cell arteritis: a clinical and pathological study.
BACKGROUND
Giant cell arteritis is a vasculitis affecting large- and medium-calibre vessels. It is not uncommon in the West and there are many large series in the literature. However, there are very few reports of giant cell arteritis among Indian patients.


METHODS
We did a retrospective study of 9 Indian patients (5 men and 4 women; age range 59-81 years [mean and median 70 years]) who had had a temporal artery biopsy for suspected giant cell arteritis at a tertiary care hospital.


RESULTS
Eight patients had biopsy-proven giant cell arteritis. The common presenting features were pyrexia of unknown origin (4), headache (6) and blurring of vision (2). The erythrocyte sedimentation rate was elevated and ranged from 25 to 120 mm at the end of the first hour (mean 96, median 105). The C-reactive protein level, which was available in 5 cases, was raised. Giant cells and inflammatory cells were seen in 7 of 8 temporal artery biopsies; a transmural lymphocytic and neutrophil Infiltrate without giant cells was present in 1 case. All patients were treated with steroids and they responded well.


CONCLUSIONS
Temporal arteritis is probably under-recognized in India. Pyrexia is a common presenting feature of the disease; temporal arteritis should be considered in the differential diagnosis of elderly patients with pyrexia of unknown origin.
