Predicitve Value of Copeptin In CO-intoxicated Patients - A Prospective Cohort Study (ALCOPOP)
Predicitve Value of Copeptin In CO-intoxicated Patients
ALCOPOP is a prospective cohort study entitled "Predicitve Value of Copeptin in CO-intoxicated Patients". The primary objective of this study is to assess the independent association between early Copeptin and / or Troponin concentrations at presentation at the emergency department with disability-free survival after carbon monoxide (CO) -intoxication. Further secondary aims are to determine the independent association between early postoperative Copeptin and / or Troponin concentrations and major adverse cardiovascular events (MACE), mortality and long-term neurological outcome.
Adult patients with acute CO-intoxication (CO-hemoglobin >10%) will be included. Main exposure will be Copeptin and Troponin concentrations. Primary endpoint will be disability-free survival at 90 days. The investigators assume to include 120 patients in 24 months

Aims of the study
To evaluate early Copeptin at arrival at emergency department based on the following:
- Discrimination for 90-day-disability-free survival (primary), 30-day-disability-free survival (secondary) and for 30-day and 90-day MACE, 30-day and 90-day all-cause mortality (secondary) as well as 30-day and 90-day-neurological outcome (secondary) and length of hospital stay (secondary).
- Independent association with 90-day disability-free survival (primary), days alive out of hospital at 30 days and 90 days (secondary) and MACE at 30 days and 90 days after CO-intoxication, 30-day and 90-day all-cause mortality and (secondary) as well as the 30-day and 90-day neurological outcome (secondary) and length of hospital stay (secondary).
To evaluate early Troponin at arrival at emergency department in terms of:
- Discrimination for 90-day disability-free survival (primary), 30-day-disability-free survival (second) and for 30-day and 90-day MACE as well as 30-day and 90-day all- cause mortality (secondary) and length of hospital stay (secondary).
- Independent association with 90-day-disability-free survival (primary), days alive out of hospital at 30 days and 90 days (secondary) and MACE at 30 days and 90 days after CO-intoxication as well as 30-day and 90 days all-cause mortality (secondary) and length of hospital stay (secondary).
The initial patient visit will take place after screening of patients and eligibility assessment and no later than on the day after admission to the emergency department (day +1). After provision of patient information and written informed consent, baseline data will be extracted from clinical source documents. The investigators plan to sample blood upon arrival in the emergency department (Troponin and Copeptin), and on day 1 and 2 after CO-intoxication (Troponin). Another blood sample will be carried out after hyperbaric oxygen (HBO) therapy to obtain a a second Copeptin measurement. Sampling will occur as far as possible concurrently to clinically indicated blood samples. Blood samples will be analyzed in a certified laboratory.
The investigators will contact all patients after 30 days and 90 days by postal mail and/or phone call (personnel blinded to biomarkers concentrations) to obtain for the 12-item WHO Disability Assessment Schedule (WHODAS) 2.0 and information on potential events. In case of the report of potential endpoints, the patient's general practitioner and/or treating hospital will be contacted for more detailed information and source documents for MACE, persistent neurological sequelae (PNS) and delayed neurological sequela (DNS) adjudication. Adjudicators will be trained in the study definitions and blinded to biomarkers concentrations.

Disability is defined as a persistent impairment in health status, as measured by the 12-item WHO Disability Assessment Schedule (WHODAS) 2.0 score, of at least 24 points when using response scores of 1-5 for each item, reflecting a disability level of at least 25% and being the threshold point between 'disabled' and 'not disabled' as per WHO guideline.
