This study described and characterized patients who experienced allergic reactions, including urticaria, angioedema, and type I hypersensitivity, caused by fibrinolytic agents. The study found that both nonfibrinolytic and fibrin-specific agents can cause these reactions.
Background: Several clinical trials of fibrinolytic agents have reported the occurrence of allergic reactions, in addition to hemorrhage. These reactions might worsen patient outcomes, especially by causing life-threatening type I hypersensitivity reactions, including anaphylaxis; however, there is a scarcity of data in this regard. Objective: This study described and characterized patients with urticaria, angioedema and type I hypersensitivity reactions caused by fibrinolytic agents. Methods: This was a retrospective study in which cases of suspected adverse drug reactions from the use of streptokinase, alteplase, and tenecteplase were evaluated over a period of 10 years at Phramongkutklao and Ratchaburi hospitals in Thailand. In addition, patient characteristics and management were assessed. Results: A total of 824 patients received fibrinolytic agents due to various indications. Of 147 patients who received streptokinase, nine (6.12%) had suspected adverse drug reactions (one case of urticaria, two cases of anaphylactic shock, and six cases of hypotension). The prescription rate of alteplase was the highest, being taken by 547 patients; however, only one patient (0.18%) reported an adverse reaction, angioedema in the face and lips. Similarly, of the 130 patients who received tenecteplase, only one patient (0.77%) developed hypotension. Conclusions: All fibrinolytic agents, either nonfibrin or fibrin-specific, can cause urticaria, angioedema, and type I hypersensitivity reactions due to their mechanism of action.
