Key result

Intravenous streptokinase in acute myocardial infarction (where 75% had low baseline titres) resulted in antibody consumption within 24 hours and an IgG1 peak at day 14.

Why the study?

Does intravenous streptokinase induce a specific antibody response in patients with acute myocardial infarction?

Implication

Streptokinase elicits sustained IgG1 response in AMI; extends immunogenicity data but leaves open implications for repeat dosing.

Structured PICO

Does intravenous streptokinase induce a specific antibody response in patients with acute myocardial infarction?

P
Population
48 patients with acute myocardial infarction, including 20 who received streptokinase and had serial blood samples taken over one year.
E
Exposure
Intravenous streptokinase
C
Comparator
Baseline values and patients unsuitable for thrombolytic therapy
O
Outcome
Specific IgG and subclass IgG1 antibody response to streptokinasesurrogate

Treatment with streptokinase for acute myocardial infarction induces a secondary immune response with specific IgG1 antibodies peaking at 14 days and remaining elevated at one year.

Cite This Study

Lynch et al. (1991) conducted an observational in acute myocardial infarction (n=48). Streptokinase was evaluated on Specific IgG and subclass IgG1 antibody response to streptokinase. Intravenous streptokinase in acute myocardial infarction (where 75% had low baseline titres) resulted in antibody consumption within 24 hours and an IgG1 peak at day 14.
