Eosinophil count at admission of compulsory obstructive pulmonary disease (COPD) patients can be used as a tool to predict mortality. Latest research conducted by a team of scientists from the Zhejiang University School of Medicine, Hangzhou, Zhejiang, China, found that eosinopenia, a condition where the eosinophil count is less than 50/uL was a strong predictor of 18-month mortality and also associated with severe infections in acute exacerbation (AE) COPD patients. This could be used as a prognosis marker for long-term mortality in hospitalized AE COPD patients, particularly people with community-acquired pneumonia. In the study, published in International Journal of Compulsory Obstructive Pulmonary Disease, the researchers explained that they had analysed 82 hospitalised AECOPD patients with community acquired pneumonia (CAP) to find the association of eosinopenia with infection. The 18-month survival was analyzed using appropriate statistical methods.
