3.3 Access to prophylactic and on-demand therapy
Eight out of 64 patients were diagnosed before their first attacks, so they were not asked to fill out a questionnaire about LTP and ODT. Thirty-eight patients (67.8%) answered the questionnaire about therapy. Only 9 patients used Danazol as prophylactic therapy, 1 used tranexamic acid.
Data about ODT used for the treatment of HAE attacks were collected in 17 patients. Only 6 patients (35.3%) were treated with appropriate drugs (2 with Icatibant or C1-INH concentrate and 4 with fresh frozen plasma infusion); eleven patients (64.7%) were treated with ineffective drugs for the disease: antihistamine (2 patients), steroid (4 patients), tranexamic acid (5 patients) (Table 3).
