Rarely, streptokinase, a thrombolytic drug for heart attacks, can cause anaphylaxis. This case highlights severe reactions and effective treatment with epinephrine, suggesting skin testing may identify at-risk patients.

Area of Science:

  • Cardiology
  • Immunology
  • Pharmacology

Background:

  • Streptokinase is a crucial thrombolytic agent for acute myocardial infarction (MI).
  • Anaphylactic reactions to streptokinase are uncommon but can be severe.
  • Understanding the mechanisms and risk factors for streptokinase-induced anaphylaxis is important for patient safety.

Observation:

  • A patient with acute MI developed profound hypotension and a widespread erythematous rash shortly after initiating intravenous streptokinase.
  • The patient required mechanical ventilation and epinephrine for blood pressure support, which was successful after other vasopressors failed.
  • This case illustrates a rare but serious adverse reaction to streptokinase therapy.

Findings:

  • Streptokinase-induced anaphylaxis is likely mediated by immunoglobulin E (IgE).

Related Experiment Videos

  • Patients experiencing anaphylaxis may have higher serum IgE concentrations to streptokinase.
  • Epinephrine is the primary treatment for anaphylaxis-induced hypotension.

    • Implications:

    • Identifying patients at risk for streptokinase-induced anaphylaxis is crucial.
    • Streptokinase skin testing may be a valuable tool for risk stratification.
    • Further research is needed to establish the role of skin testing in streptokinase therapy protocols.
