↵1-150 Age mean 73 (range 64–85). At the time of the biopsy four patients were being treated with corticosteroids, three with NSAIDs, five were receiving no anti-inflammatory treatment. Mean ESR 81 mm/1st h (range 50–132).
↵1-151 NSAID = non-steroidal anti-inflammatory drug; ESR = erythrocyte sedimentation rate.
