MARKERS OF ALZHEIMERS DISEASE
20180010182 · 2018-01-11 · ·

The use of markers that participate in inflammatory processes and are associated cytokines in the diagnosis, treatment or prophylaxis of diseases is disclosed. Specifically, cytokines are used to diagnose or treat non-neoplastic or non-leukaemic diseases such as autoimmune diseases or neurodegenerative disorders by the process of taking a DNA bearing sample from a subject animal and analysing the sample to determine the allelic variants present at one or more of the SNP loci at positions −1082, −819 and −592 of the gene encoding IL-10. A method of treating Alzheimer's disease, autoimmune diseases or other neurodegenerative disorders is disclosed by modulating, that is augmenting or decreasing, the function of a gene having one of the allelic polymorphisms of IL-10. IL-6 inhibitors and IL-10 promoters can be used in the manufacture of a medicament for the treatment of prophylaxis of Alzheimer's disease.

Diagnosis and risk stratification of fungal infections

The invention relates to a method for the diagnosis and/or risk stratification of invasive fungal infections (IFI)/invasive fungal diseases (IFD) and in particular associated with sepsis or septic shock, wherein a determination of the marker proadrenomedullin (proADM) or a partial peptide or fragment thereof, in particular midregional proadrenomedullin (MR-proADM), or contained in a marker combination (panel, cluster), is carried out from a patient to be examined. Furthermore, the invention relates to a diagnostic assay and a kit for carrying out the method.

SYSTEM FOR DETECTING INFECTION IN SYNOVIAL FLUID

The invention provides methods and systems for detecting a biomarker in a synovial fluid wherein the system also includes a control to ensure that the test sample is indeed synovial fluid. The biomarkers and the control for synovial fluid can be identified using proteomic methods, including but not limited to antibody based methods, such as an enzyme-linked immunosorbant assay (ELISA), a radioimmunoassay (RIA), or a lateral flow immunoassay.

METHODS FOR DISEASE ASSESSMENT USING DRAIN FLUID

The present invention provides methods for using surgical drainage waste fluid as a means for diagnosing disease, assessing disease progression, predicting metastatic disease, assessing cancer metastasis, disease staging, molecular staging, and assessing metastatic disease. During surgery, suction is used to drain fluids such as blood, tissue fluids, and other bodily fluids away from the surgery site. The suction drainage fluid waste, also called drain fluid, is removed from the patient during the surgical procedure. Because surgical drain fluid is typically viewed as something that is not useful, it is disregarded and thrown away during the surgery. Instead, the invention provides that drain fluid, which is mostly lymphatic fluid and interstitial fluid, is diagnostically rich and contains important information for assessing, diagnosing, and treating disease. The methods of the invention use this waste fluid for the valuable data it contains. Therefore, while a patient is already undergoing surgery for a medical condition, the waste drain fluid is sampled and analyzed for biomarkers or other molecular indicia of disease.
