OBJECTIVE: To test the hypothesis that the arachodinic acid metabolites prostaglandin E2 (PGE2) and 15-(S)-hydroxyeicosatetraenoic acid (15(S)-HETE) in cerebrospinal fluid (CSF) are elevated and reflect neuroinflammation and degenerative changes in multiple sclerosis (MS). PATIENTS AND METHODS: We measured PGE2 and 15(S)-HETE concentrations, as well as markers of axonal and astroglial injury in CSF from 46 MS patients, 46 healthy siblings and 50 controls. RESULTS: We found elevated levels of both PGE2 and 15(S)-HETE in MS compared with the control and sibling groups. Siblings had lower PGE2 levels and higher 15(S)-HETE levels than controls. There were no correlations between either PGE2 or 15(S)-HETE and clinical scores of MS severity or biochemical markers of axonal or astroglial injury. CONCLUSION: These data suggest no direct involvement of PGE2 and 15(S)-HETE in the MS disease process. Rather, the elevated levels reflect a general up-regulation of arachidonic acid metabolism and neuroinflammation.
