A method for determining the concentration of lactulose in a blood sample comprises the steps of converting lactulose in the blood sample into an entity including galactose, and converting the galactose into D-galacto-hexodialdose and hydrogen peroxide, which is detected. The detected quantity is processed to generate an output which is representative of the concentration of lactulose in the blood sample.

The present disclosure provides methods for the treatment of mast cell gastritis, mast cell esophagitis, mast cell colitis, mast cell enteritis, mast cell duodenitis, and/or mast cell gastroenteritis. In particular, the present disclosure provides methods for the treatment of mast cell gastritis, mast cell esophagitis, mast cell colitis, mast cell enteritis, mast cell duodenitis, and/or mast cell gastroenteritis through administration of antibodies that bind to human Siglec-8 or compositions comprising said 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.

A method is useful for diagnosing AIG, which includes the step of detecting whether autoantibodies against the beta-subunit of the gastric H.sup.+/K.sup.+-ATPase are present or not in a sample comprising antibodies. The method utilizes a diagnostically useful carrier that contains a solid phase on which an agent for the specific capture of the autoantibody is immobilized. Furthermore, the diagnostically useful carrier includes a solid phase on which an agent for the specific capture of an autoantibody against the beta-subunit of the gastric H.sup.+/K.sup.+-ATPase is immobilized.

According to an example aspect of the present invention, there is provided an improved method for screening of asymptomatic and symptomatic subjects with Helicobacter pylori infection, atrophic gastritis with related risks and/or disturbed gastric function based on whole blood samples, sample collection time and sample storage temperature, as well as relevant biomarker content analysis.

The present invention provides an antibody combination that can be used to detect regenerating islet-derived protein 1? (REGIA), each antibody in the antibody combination can specifically bind to REGIA with high affinity so as to form a double-antibody sandwich form, thereby enabling qualitative and quantitative detection of human REGIA. The antibody combination or an ELISA detection kit comprising the antibody combination can be used for auxiliary diagnosis or disease risk prediction of REGIA-related diseases.
