Giant cell arteritis: was commoner with jaw claudication, abnormal temporal arteries or diplopia.
|
|
|
Clinical bottom line (level 4)
-
40% of patients with suspected giant cell arteritis had it.
-
Temporal artery biopsy could not effectively rule out temporal arteritis, but a positive result was diagnostic.
-
Temporal arteritis was more likely in patients with jaw claudication
(LR+12.4)
, or a clinically abnormal temporal artery
(LR+1.70)
.
-
Temporal arteritis was less likely in patients with tongue claudication
(LR+0.11)
.
