Abstract
Release of prostaglandin E (PGE) was examined in leukocyte cultures from patients with definite MS who had had at least one recent exacerbation, others with chronic progressive or stable MS, and healthy controls. MS patients had higher baseline levels of PGE than did controls. Patients with active symptoms exhibited a sharp increase in PGE release early in or just before the onset of clinical symptoms. Levels dropped early in exacerbation immediately after the burst in PGE synthesis activity. Values gradually increased to control levels and then to preexacerbation levels. Similar rises and falls were not seen in stable MS. MS patients may have a circulating population of activated leukocytes that produce PGE.
