Methods for treating coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, is described. The methods can be used to reduce the severity of outcomes related to COVID-19, such as hospitalization and ventilation. For example, treatment of a subject with a therapeutic agent that neutralizes interleukin 13 (IL-13) can result in reduced risk for mechanical ventilation in the subject. Also described are methods of predicting risk of mechanical ventilation in subjects with COVID-19.

The present invention relates to methods and systems for predicting the likelihood of acute respiratory distress syndrome (ARDS) in adult subjects. The invention further relates to methods of treatment and identification of subjects with an increased likelihood of developing ARDS as determined by the disclosed methods.

Nitrous oxide and oxygen for use in treating ARDS caused by viral and bacterial infections, injuries, or other conditions that have resulted in acute, excess activation of the cytokine system in a patient in need thereof is provided. The treatment comprises administering nitrous oxide and oxygen to the patient by inhalation before, during, and/or after ARDS occurs. It is also applicable for treating, alleviating, and/or preventing an aftereffect of said conditions. A composition, duration, an interval, and a total amount of nitrous oxide and oxygen depend on each patient's individual situation and needs. Inhalation of nitrous oxide and oxygen can also stop the post ARDS symptoms that remain after an acute ARDS condition such as, but not limited to viral infections, bacterial infections, injuries, or any condition that results from any cytokine storm. Inhalation of nitrous oxide and oxygen can also treat local cytokine damages caused by said conditions.

Methods and kits for screening, diagnosing, detecting or predicting a patient outcome/risk in a patient with a respiratory illness, the method comprising: a. obtaining a sample obtained from the patient; b. quantitatively measuring in the sample a polypeptide level of one or more biomarkers selected from: IL-6, CXCL8, IL-10, IL-IRA, IL-2, IL-4, IL-7, IL-9, IL-13, IL-17, IFN-g, IP-10, MCP-1, G-CSF, GM-CSF, FGF-basic, SCGF-β, GRO-α, MIP1-α, MIP1-β, CK-18, PDGF-bb, caspase 3, HMGB-1, TNF α, VEGF, sTNFR1 and sTREM1; and c. i) comparing the level of the one or more biomarkers in the sample with a control or cut-off level, wherein the differential level is indicative of patient outcome risk; or ii) using the polypeptide level of several of the biomarkers in combination, as inputs for an algebraic calculation or machine learning model of patient outcome risk.

Devices and methods for conducting lateral flow immunochromatographic assays may be used, in some aspects, to measure the level of glutathione-S-transferase pi in a biological fluid collected from a human subject suspected of having had a stroke in order to determine whether the subject has had a stroke or to aid in the selection and administration of a treatment for the suspected stroke. In other aspects, such devices may be used to diagnose, monitor, and/or treat acute respiratory distress syndromes (ARDS), such as the novel coronavirus designated COVID-19.

A pharmaceutical composition for administering directly to the pulmonary tract of a subject includes a salt of triiodothyronine and a pharmaceutically acceptable buffer, adjusted to a pH of 5.5-8.5. The composition can be administered prophylactically or therapeutically to a subject to treat lung inflammation or pulmonary edema.

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 concerns methods and tools for analysing biomarkers useful for diagnosing an individual, in particular a newborn, with a respiratory disease, especially a newborn suffering from respiratory distress syndrome (RDS). The method and tools of the invention can in one embodiment be used for very rapidly detecting the ratio between lecithin and sphingomyelin in very small body fluid samples, e.g. gastric aspirate of a newborn. The invention is thus useful for obtaining a rapid treatment of RDS by administration of surfactant.

The present invention relates to mutants of S100A12 having at least one mutation in the high-affinity calcium binding hand or the low-affinity calcium binding hand or the zinc binding region. The present invention also relates to methods of detecting S100A12 dimers in a sample as well as methods of diagnosis using the S100A12 mutant of the invention, as well as to diagnostic compositions and kits comprising such an S100A12 mutant. The present invention further relates to a method of generating an antibody that specifically binds to an S100A12 dimer using the S100A12 mutant of the invention, as well as to an antibody that specifically binds to an S100A12 dimer.

Disclosed is a method for assisting prediction of exacerbation of respiratory infection, comprising measuring a biomarker in a specimen collected from a subject suffering from a respiratory infection or a subject suspected of having a respiratory infection, wherein the biomarker is at least one selected from the group consisting of IFNλ3, CCL17, CXCL11, IP-10, IL-6 and CXCL9, and a measured value of the biomarker is used as an index to predict exacerbation of the respiratory infection.
