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 …

Abstract
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.
