A method to determine the severity of a disease of chronic inflammation in a patient, comprising the steps of (1) collection or preparation of a bodily fluid, tissue or lavage and (2) measurement of ALX receptor ligands or ALX receptor expression in the fluid, tissue, or lavage, wherein the level of ALX receptor ligands predicts a clinical outcome or choice of treatment modality, is disclosed.

The present invention relates to a method for diagnosing a respiratory tract infection in a subject, comprising determining in a sample from said subject the level of High-Mobility-Group-Protein B1 (HMGB1), and/or determining in a sample from said subject the level of a histone protein, and/or determining in a sample from said subject the level of Insulin-like growth factor binding protein, acid labile subunit (IGFALS), wherein the subject is diagnosed with a bacterial respiratory tract infection when the level of IGFALS is below a predetermined threshold level and/or the level of the histone protein is above a predetermined threshold value, and/or wherein the subject is diagnosed with a respiratory tract infection when the level of HMGB1 is above a predetermined threshold level.

The present invention is related to novel methods for categorizing and treating a population of subjects that are at risk for increased pulmonary exacerbation and disease progression.

The present invention is related to novel methods for categorizing and treating a population of subjects that are at risk for increased pulmonary exacerbation and disease progression.

The present invention is directed to the use of (1) mucin concentration in sputum; (2) individual airway mucins MUC5AC and MUC5B ratio (MUC5AC/MUC5B) in sputum; and (3) combination of both measurements (Kesimer MUCQuant index) that can be used as an objective biomarker for differential diagnosis of smoking status and chronic bronchitis (CB), disease severity of CB (mild, moderate, and severe), exacerbation status, monitoring progression of CB, and guiding of therapies for CB. In addition, the ratio of amount of IgGFc-binding protein (FCGBP) and the amount of bactericidal/permeability-increasing fold-containing family member A1 (BPIFA1 (or SPLUNC1)) present in a sputum sample from a subject may be used in combination with the Kesimer MUCQuant index (Kesimer MUCQuant Plus index) for differential diagnosis of smoking status and CB, disease severity of CB, exacerbation status, p monitoring progression of CB, and guiding of therapies for CB.

A device configured for monitoring a concentration of at least one volatile breathing compound. The device can include a gas interface having a mouthpiece to blow into. A connector can couple the interface to a conduit connected to a flow meter and a valve. The flow meter can measure a predefined first flux level of a patient respiratory gas flux. The gas conduit can also connect to an inlet into an intermediate gas storage. The intermediate gas storage can let patient respiratory gas exhaust in response to the flow meter sensing an expiration of the patient respiratory gas flux. A pump can draw the patient respiratory gas with a predefined second flux level in a reverse direction out of a sampling gas outlet and into a gas sampling line where exhaled concentrations of volatile breathing compound are by a detector.

The present invention is related to novel methods for categorizing and treating a population of subjects having cystic fibrosis (CF) and who are at risk of severe pulmonary exacerbation comprising detecting the expression levels of genes in a gene panel consisting of TLR2, ADAM9, PLXND1, CD163, CD36, CD64, CSPG2, IL32, HPSE, and HCA112 and aggressively treating the subject when the expression levels of the genes from the gene panel predicts the subject is at risk for severe pulmonary exacerbation.
