Abstract
We suggest that polymyalgia rheumatica with giant cell arteritis (PR-GCA) is an arachidonic acid metabolites mediated disease which can be diagnosed more accurately and monitored more precisely for therapeutic benefits by the serial determinations of the major urinary prostaglandin F, serum urinary lysozymes, serum acid phosphatase, and serum angiotensin converting enzyme rather than by the erythrocyte sedimentation rate, and, when necessary by temporal artery biopsy. The pathogenetic role proposed for prostaglandins (PG) and, even more precisely perhaps, the leukotrienes in this disease is consistent with the several published clinical observations that non-steroidal anti-inflammatory drug treatment produces in some cases a therapeutic paradox of symptomatic relief with concurrent, if clinically silent, progression of the arteritis, even to blindness. Furthermore, the impressive response of PR-GCA to low maintenance dose steroid therapy, a clinical conundrum for decades, is rationally explained on the basis of depressed or obstructed PG metabolism early on in the metabolic cascade. These views warrant clinical evaluation, confirmation or correction in whole or in part, and may increase our understanding of PR-GCA.
