PURPOSE: Antiplatelet therapy is used for the primary and secondary prevention of thrombotic diseases such as acute coronary syndrome (ACS). These patients are more vulnerable to infections, as such, strategies are required to mitigate these risks.
METHODS: We conducted a retrospective cohort study using TriNetX, a global federated health research network that includes both inpatient and outpatient electronic medical records from health care organizations worldwide. Patients ≥18 years old, after ACS, who were placed on aspirin and ticagrelor were compared with patients placed on aspirin and clopidogrel or prasugrel. Patients were identified using International Statistical Classification of Diseases and Related Health Problems terminology codes. After propensity score matching (1:1), a total of 239,358 patients were identified in each cohort. The primary outcomes of interest investigated were rates of (1) acute and subacute infective endocarditis, (2) sepsis of unknown origin, (3) staphylococcus arthritis, (4) cellulitis and acute lymphangitis, (5) Staphylococcus aureus bacteremia, and (6) staphylococcal pneumonia after initiation of treatment. Outcomes were analyzed at 1, 3, and 5 years.
FINDINGS: At 5 years, a combination of aspirin and ticagrelor, compared with a combination of aspirin and clopidogrel or prasugrel, was associated with significantly reduced rates of (1) acute and subacute endocarditis (hazard ratio [HR] plus 95% CI) (HR = 0.85; 0.77-0.945; P = 0.030), (2) sepsis of unknown origin (HR = 0.89; 95% CI, 0.86-0.91; P < 0.0001), (3) cellulitis and acute lymphangitis (HR = 0.89; 95% CI, 0.87-0.92; P < 0.0001, and (4) Staphylococcus aureus bacteremia (HR = 0.72; 95% CI, 0.61-0.85; P = 0.0007). However, a combination of aspirin and clopidogrel was associated with a marinally lower risk of staphylococcal pneumonia (HR = 1.04; 95% CI, 1.01-1.062; P < 0.0001).
IMPLICATIONS: A combination of aspirin and ticagrelor is associated with a lower rate of a variety of bacterial infections. This combination warrants further investigation in in-vitro studies to tease out mechanisms and through clinical randomized trials in groups who have ACS and are at high infection risk.
