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 27 patients. Only 9 patients were treated with appropriate drugs (2 with Icatibant or C1-INH concentrate and 7 with fresh frozen plasma infusion); 18 patients were treated with ineffective drugs for the disease: antihistamine (2 patients), steroid (5 patients), tranexamic acid (11 patients) (Table 3). Eleven patients answered that they did not use any treatment to resolve HAE attacks, they are waiting 2-4 days until the swelling will abates.
