Application of Visual Gene Clip-Based Tailored Therapy for the Eradication of .

Biomed Res Int 2021 10;2021:6150628. Epub 2021 Apr 10.

Department of Gastroenterology, Peking University Shenzhen Hospital, Shenzhen, Guangdong Province, 518036, China.

Background: eradication with therapies employing a proton pump inhibitor (PPI) and antimicrobial agents is mainly achieved via bacterial susceptibility to antimicrobial agents and the magnitude of acid secretion inhibition. However, annual eradication rates have greatly declined in Mainland China, and therefore, tailored eradication regimens that inhibit acid secretion and employ optimal antimicrobial agents determined based on gene clip testing may improve eradication rates. This study was aimed at evaluating the efficacy of tailored eradication therapy guided by visual gene clip testing for antibiotic resistance and PPI metabolism genotypes. Read More

Heat-killed Helicobacter pylori upregulates NKG2D ligands expression on gastric adenocarcinoma cells via Toll-like receptor 4.

Helicobacter 2021 Apr 29:e12812. Epub 2021 Apr 29.

Faculty of Medicine, Immunology Program, Biomedical Sciences Institute (ICBM), University of Chile, Santiago de Chile, Chile.

Background: Natural killer (NK) cells are paramount for immunity against infectious agents and tumors. Their cytokine and cytolytic responses can be mediated by natural killer group 2, member D (NKG2D), an activating receptor whose ligands (NKG2DL) expression is induced in conditions of cell stress and malignant transformation. Since sustained expression of NKG2DL MICA is related to lower survival rates in gastric adenocarcinoma patients, and Helicobacter pylori infection contributes to tumorigenesis; we asked whether H.

Dysbiotic gut microbiota in inflammatory rosacea patients: another clue towards the existence of a brain-gut-skin axis.

Br J Dermatol 2021 Apr 29. Epub 2021 Apr 29.

Dermatology Department, Ramon y Cajal University Hospital, University of Alcala, Instituto Ramón y Cajal de Investigación Sanitaria (IRYCIS), Madrid, Spain.

Rosacea is a chronic inflammatory disease that primarily affects young and middle-aged Caucasian women. Its etiology is multifactorial and appears to be determined by genetic predisposition, alteration of the neurovascular and immune response, as well as an altered dialogue with the microbiota. Additionally, the disease has been linked to gastrointestinal disorders such as Helicobacter pylori infection or small intestine bacterial overgrowth and even neurological disorders such as Parkinson's disease, revealing the existence of a brain-gut-skin axis.
