HOST DNA AS A BIOMARKER OF CROHN'S DISEASE

The present invention relates to an in vitro method for diagnosing Crohn disease in a subject comprising: a) obtaining a biological sample from said subject, b) analysing the relative abundance of the host DNA in said sample, and, c) diagnosing that said subject suffers from Crohn disease if said re...

Summary:The present invention relates to an in vitro method for diagnosing Crohn disease in a subject comprising: a) obtaining a biological sample from said subject, b) analysing the relative abundance of the host DNA in said sample, and, c) diagnosing that said subject suffers from Crohn disease if said relative abundance is higher than a reference value. The present invention also relates to an in vitro method for diagnosing the state (stable or unstable) of the Crohn disease in a subject, comprising the steps of: a) obtaining a biological sample from said subject, b) analysing the relative abundance of the host DNA in said sample, and, c) diagnosing that said subject has a Crohn disease in an unstable state if said relative abundance is higher than another reference value. La présente invention concerne un procédé in vitro permettant de diagnostiquer la maladie de Crohn chez un sujet comprenant les étapes consistant à : a) obtenir un échantillon biologique auprès dudit sujet, b) analyser l'abondance relative de l'ADN hôte dans ledit échantillon, et, c) diagnostiquer que ledit sujet souffre de la maladie de Crohn si ladite abondance relative est supérieure à une valeur de référence. La présente invention concerne également un procédé in vitro permettant de diagnostiquer l'état (stable ou instable) de la maladie de Crohn chez un sujet, comprenant les étapes consistant à : a) obtenir un échantillon biologique auprès dudit sujet, b) analyser l'abondance relative de l'ADN hôte dans ledit échantillon, et, c) diagnostiquer que ledit sujet a une maladie de Crohn dans un état instable si ladite abondance relative est supérieure à une autre valeur de référence.
