The present invention relates to methods and compositions for monitoring, diagnosis, prognosis, and determination of treatment regimens in appendicitis patients and in patients at risk for appendicitis. In particular, the invention relates to using assays that detect one or more biomarkers as diagnostic and prognostic biomarker assays in such patients.

Described herein are methods and systems for the detection of anti-vinculin antibodies, for determining a presence or likely presence of a gastrointestinal motility disorder, bladder motility disorder, or fibromyalgia. Further provided are methods of selecting and/or administering a therapy based on the presence or absence of anti-vinculin antibodies.

The present invention relates to methods for diagnosing, monitoring, and optionally treating eosinophilic gastritis (EG) and/or eosinophilic gastroenteritis (EGE), the methods comprising assaying one or more tissue, serum, or plasma biomarkers in a biological sample from the subject.

The invention relates to the prognosis and treatment of colon cancer. In particular, the present invention concerns the role of intestinal microbiota in the anticancer immune response elicited by ileal enterocytes succumbing to apoptosis, and provides immunogenic compositions for treating colorectal cancer (CRC), as well as signatures for prognosing CRC evolution.

Compositions and methods for nucleic acid isolation from an environmental or biological sample comprising nucleic acid-analysis interferents, particularly from microbiome-containing samples, are provided.

The invention provides antibodies that specifically bind to an epitope containing N-acetylglucosamine or N-acetyl-galactosamine expressed by a cancer cell or an inflammatory cell. Also provided are compositions including these antibodies, as well as polynucleotides, vectors, host cells, and methods useful for production thereof. Further provided are methods and kits for treating or preventing cancer in an individual by administering to the individual an antibody that specifically binds to an epitope containing N-acetylglucosamine or N-acetyl-galactosamine, optionally in combination with another anti-cancer agent. Still further provided are methods and kits for treating or preventing gastrointestinal disease in an individual by administering to the individual an antibody that specifically binds to an epitope containing N-acetylglucosamine or N-acetyl-galactosamine. Yet further provided are methods and kits for detecting the presence of cancer cells in an individual including an antibody that specifically binds to an epitope containing N-acetylglucosamine and/or N-acetyl-galactosamine.

The present embodiments relate to selection of agents effective in reducing or preventing gastrointestinal pain in a subject. Such an agent is selected and identified if it is capable of reducing spontaneous and/or induced transient receptor potential vanilloid 1 (TRPV1) activation.

Compositions and methods for the treatment and diagnosis of eosinophilic esophagitis disclosed.

The invention relates to a method for binding or capturing autoantibodies directed to various Glycoprotein 2 (GP2) isoforms. In particular the invention provides an in vitro method for the diagnosis of an autoimmune disorder by the detection of autoantibodies that bind one or more isoforms of GP2. The invention is characterized by the provision of multiple isoforms of GP2 as autoantibody targets and encompasses the practical utilization of the finding that the isoform specificity of anti-GP2 autoantibodies enables determination of particular autoimmune diseases. The invention also provides a system and kit developed for carrying out the claimed method. The present invention is useful for determining whether a sample from an individual comprises autoantibodies associated with an autoimmune disease, and for differentiating between multiple autoimmune diseases that exhibit similar symptoms, such as Celiac disease (CeD), Crohn's disease (CD), primary sclerosing cholangitis (PSC), and/or ulcerative colitis (UC).

The present invention relates to compositions and methods for visualizing disease-specific T-cells. In particular, the present invention relates to compositions and methods for use in the diagnosis, monitoring of progression, monitoring of response to therapy, and selection of patients for therapy of autoimmune diseases characterized by selective expansion of disease-specific effector memory T-cells.
