Abstract/OtherAbstract:
It has been reported that the anti-inflammatory action of glucocorticoids is due to the inhibition of phospholipases. Consequently, after high-dose steroid treatment in humans a decrease in cyclooxygenase products should be expected. In 15 patients (10 males, 5 females, 29-62 y) undergoing 6-methyl-prednisolone-treatment (40-80 mg daily) for various clinical reasons and in 5 healthy volunteers (4 male, 1 female, 28-37 y) receiving 500 mg 6-methyl-prednisolone daily for 3 days plasma- and serum-thromboxane B2 (TXB2), as well as bicyclo-prostaglandin E2 (bicyclo-PGE2) were monitored over 3 weeks. In the entire follow-up period, however, no significant change in either serum- or plasma-TXB2 or bicyclo-PGE2 could be measured in either, patients and volunteers, under glucocorticoid-treatment. These findings indicate that even high-dose glucocorticoid-treatment does not affect the serum- and plasma-metabolites of the eicosanoids examined. It is concluded that in humans a significant inhibition of phospholipases by glucocorticoids and subsequently reduced formation of cyclooxygenase products seems to be rather unlikely.
