Abstract
BACKGROUND Non-allergic angioedema is largely driven by increased plasma levels of bradykinin and over-activation of bradykinin receptor type II (B2), but the specific downstream signalling pathways remain unclear. The aim of this study was to identify signal transduction events involved in bradykinin-induced dermal extravasation. METHODS Quantification of dermal extravasation was accomplished following intradermal (i.d.) injection of bradykinin or the B2 agonist labradimil in mice with endothelial NO-synthase (eNOS) deficiency and in C57BL/6J mice pre-treated with vehicle, NO-synthase or cyclooxygenase (COX) inhibitors. In the multicentre clinical study ABRASE, 38 healthy volunteers received i.d. bradykinin injections into the ventral forearm before and after oral treatment with the COX inhibitor ibuprofen (600 mg). The primary endpoint of ABRASE was the mean time to complete resolution of wheals (TTCR) and the secondary endpoint was the change of maximal wheal size. RESULTS Neither NOS inhibitors nor eNOS deficiency altered bradykinin-induced extravasation. In striking contrast, the COX inhibitors ibuprofen, diclofenac, SC560 and celecoxib significantly diminished this extravasation when given before injection. As for diclofenac, a similar but significantly lower effect was observed when given after i.d. injection of bradykinin. Similar results were obtained when bradykinin was replaced by labradimil. In volunteers, ibuprofen significantly reduced TTCR (P < 0.001) and maximal wheal size (P = 0.0044). CONCLUSION These data suggest that COX activity contributes to bradykinin-induced dermal extravasation in mice and humans. In addition, our findings may open new treatment options and point to a potential activity of drugs interfering with the release of the COX substrate arachidonic acid, e.g. glucocorticoids.
