[0125] marker measurement

[0126] MR-proANP was detected using a novel fully automated sandwich immunoassay system on the B.R.A.H.M.S KRYPTOR (B.R.A.H.M.S GmbH, Hennigsdorf / Berlin, Germany). The stochastic on-line analyzer uses a sensitive Time Resolved Amplified Cryptate Emission (TRACE) technique based on the non-radioactive transfer between 2 fluorophores, europium cryptate and XL665. This automated assay is essentially based on a sandwich chemiluminescent assay described in detail elsewhere ( Morgenthaler et al 2004.Clin Chem50:234-6 ), and for other studies ( Khan et al. 2008. J Am Coll Cardiol 51:1857-64; Gegenhuber et al. 2006. Clin Chem 52: 827-31 ). For MR-proANP detection, 14 μl of patient serum was incubated for 14 min. The measurement range is 0-10000pmol / L, the detection limit is 2.1pmol / L, and the quantification limit is 4.5pmol / L. The intra-assay CV was 1.2% and the inter-laboratory CV was 5.4%. This assay uses the same antibody pair as the reference...

Abstract

The present invention relates to a method for prognosis and / or risk assessment and / or monitoring in the treatment and / or management of COPD patients, said method comprising the steps of: i) providing a sample of body fluid from said patient, ii) determining said The level of at least one biomarker in the sample selected from proadrenomedullin (proADM), pronatriuretic peptide, provasopressin (proAVP) and procalcitonin (PCT) or their length iii) determination of the BODE-index parameters body mass index (BMI, parameter B), degree of airflow obstruction (FEV1, parameter O), dyspnea (parameter D) and exercise capacity (parameter E) 1, 2 or 3, iv) correlating said levels of said at least one biomarker determined in step ii) in combination with said 1, 2 or 3 BODE index parameters determined in step iii) with COPD Associated with prognosis and / or risk scoring and / or monitoring of patient treatment and / or management.

Description

[0001] field of invention [0002] The present invention is in the field of clinical diagnostics. In particular, the present invention relates to the determination of biomarker levels in samples derived from bodily fluids of COPD patients. [0003] Background of the invention [0004] Chronic obstructive pulmonary disease (COPD), a generally preventable and treatable disease, is characterized by persistent airflow limitation that is often progressive and associated with an enhanced chronic inflammatory response in the airways and lungs to noxious particles or gases . Symptoms of COPD include dyspnea, prolonged cough and chronic expectoration. Spirometry is required to make a clinical diagnosis of COPD. Post-bronchiectasis FEV less than 0.70 1 The presence of / FVC (forced expiratory volume in 1 second / forced vital capacity) confirms the presence of persistent airflow limitation and thus COPD. [0005] The prevalence of clinically relevant COPD is approximately 4–6% in the E...
