Prognosis Value of Pro-adrenomedullin in Acute Exacerbations of COPD in ER
Prognosis Value of Pro-adrenomedullin in Acute Exacerbations of COPD in ER
The purpose of this study is to determine whether pro-adrenomedullin (Mr proADM)in addition
 to clinical evaluation is effective to predict outcome of acute exacerbations of COPD
 patients visiting the emergency room(ER).
Acute exacerbation of COPD (AECOPD)are usual and frequent cause of admission in emergency
 room (ER). No validated clinical or biological predictor of evolution are available.

 The main objective is to determine the prognosis value of Mr proADM in addition to the
 clinical risk stratification for AE COPD patients in ER.

 Patients presenting with a AECOPD diagnosis in ER will have a blood sample collected and
 freezed at their admission. Mr proADM will be assessed at the end of the study. Clinicians in
 charge of patients will not have the result during the management of their patients. This
 study implies no change in the patients' management.

 Data related to the patients'demographic,current exacerbation and basic COPD characteristics
 will be collected.
