Hostitelský mikrobiom spolu s genetickou predispozicí jedince jsou důležitými faktory
v etiopatogenezi refluxní choroby jícnu (GERD), která významně zvyšuje riziko rozvoje ezofagitidy (RE), Barrettova jícnu (BE) a adenokarcinomu ezofagu (EAC). Cílem projektu je determinace markerů na úrovni mikrobiomu, genů hostitele a jejich interakcí pro časnější diagnostiku a predikci rozvoje BE a EAC.
Projekt obsahuje 3 části: (1) analýzu metagenomu a metatranskriptomu v několika lokalitách
gastrointestinálního traktu (GIT) u pacientů s GERD, (2) analýzu hostitelského exomu a transkriptomu ve tkáni jícnu u pacientů s BE/EAC, a (3) analýzu genetického profilu pacientů s GERD a jeho komplikacemi. Mutace v exomu/genomu pacienta a míra exprese genů ve tkáni jícnu budou korelovány s mikrobiomem a jeho funkční aktivitou v GITu a klinickým nálezem doplněným o in vivo endomikroskopii.
Na základě získaných dat se pokusíme navrhnout modifikaci standardního režimu péče o pacienty s GERD s cílem předejít pokročilým a ireverzibilním změnám snižujícím kvalitu života pacientů, resp. ohrožujících je na životě.
