Background
Eosinopenia has been shown to be a prognostic factor in bacteremia, chronic obstructive
pulmonary disease, and myocardial infarction, but studies focusing on cerebral infarction
are lacking.
Methods
We conducted a retrospective study of 405 patients admitted to the Asahi General Hospital
from June 2011 to September 2014 with a diagnosis of cerebral infarction within 24 hours
after symptom onset. Differences in mortality, mortality associated with infection,
and the prevalence of infection within 2 months of hospital admission were assessed
between patients with and without eosinopenia at presentation.
Results
Patients with eosinopenia had a significantly higher mortality rate (hazard ratio
(HR) 2.54, 95% confidence interval (CI) 1.17-5.21, P = .01), mortality associated with infection (HR 28.7, 95% CI 4.9-542.2, P < .0001), and an increased prevalence of infection (HR 1.83, 95% CI 1.12-2.89, P = .01) than patients without eosinopenia. Patients with neutrophilia and eosinopenia
showed a significantly higher mortality rate than patients without neutrophilia (HR
3.15, 95% CI 1.40-6.92, P = .007), whereas patients with neutrophilia without eosinopenia showed no significant
difference in mortality compared with patients without neutrophilia (HR 1.57, 95%
CI .56-3.93, P = .37). Eosinopenia was a significant risk factor in 2-month mortality rate in multivariate
analyses (HR 2.34, 95% CI 1.05-4.95, P = .04).
Conclusions
Eosinopenia is a novel predictive factor for complications after acute cerebral infarction.
Stroke patients with eosinopenia should be monitored carefully for infection.
