Objective: The aim of our study was to discover the histological modifications occurring in HAE attacks. Strategies: Post mortem macro-, microscopic and immunohistological assessment of upper airway tissues of a patient with HAE as a consequence of C1 inhibitor deficiency (C1-INH-HAE) type 2 who died from laryngeal HAE attack was compared with a non-HAE patient who died from other situation with out any signs of angioedema. Outcomes: In comparison to the manage patient, we demonstrated stronger T cell/monocyte infiltration and also a more intense C1-INH staining within the C1-INH-HAE patient. The expression of both bradykinin receptors (B1/B2) was observed using a slightly reduced level within the C1-INH-HAE patient than in the manage patient. PAR1 expression was strongly lowered within the C1-INH-HAE patient suggesting overactivation of this hyperpermeability inducing receptor. Conclusion: Our distinctive case and novel results correspond to the knowledge about C1-INH and BDKRs observed in plasma; on the other hand, it revealed new information regarding the pathomechanism of HAE attack focusing on the possible involvement of PAR1 in edema formation.PMID:23724934 This observation, if it is actually verified by subcutaneous biopsy research, might designate a brand new therapeutic target in HAE.
