[Horton's disease: retrospective study of 33 cases and review of the literature].
Temporal arteritis is still often overlooked in 1982 as shown by the diagnostic delay reported in a retrospective review of 33 patients and in the series previously published in the medical literature. Clinical features to be especially kept in mind are the occasional nature of temporal signs, the pathognomonic value of jaw claudication and the existence of signs which may constitute a premonitory syndrome of blindness. The frequent rise in alkaline phosphatase levels is often misleading. In patients over 65 with an unexplained inflammatory syndrome, biopsy of both temporal arteries should be promptly performed, prior to the unpleasant and costly investigations designed to detect an occult carcinoma. Corticosteroids are still the best treatment of giant cell arteritis but the optimal initial dosage remains unknown as no data from randomized trials are available. Symptomatic relapses have been reported up to 10 years (5 years for ocular symptoms) after onset of the disease. Because of this protracted course, which makes adequate follow-up difficult to ensure, recovery rates from different series are at variance. The main side-effects of maintenance corticosteroid therapy in these elderly patients are osteoporosis, which warrants systematic countermeasures, and probably an increased rate of atheromatosis.
