... admission rate or with higher mortality. Accordingly, we believe that the total eosinophil count and /or eosinopenia have little (if any) value in predicting the severity of CAP in HIV- infected patients. Letter Role ... They propose that eosinopenia may become a helpful clinical tool in intensive care unit (ICU) practices. They included different types of severe infection...
