D\u00e9chet produit par le foie ou issu de l\u2019alimentation, l\u2019oxalate de calcium peut, en cas d\u2019une concentration excessive, former des calculs r\u00e9naux.

Des chercheurs ont r\u00e9ussi \u00e0 implanter une bact\u00e9rie intestinale g\u00e9n\u00e9tiquement modifi\u00e9e chez des patients pour \u00e9liminer le compos\u00e9 \u00e0 l\u2019origine des calculs r\u00e9naux.<\/p>\n

Fr\u00e9quents, douloureux, souvent r\u00e9cidivants,\u00a0les calculs r\u00e9naux<\/a>\u00a0concernent pr\u00e8s d\u2019un adulte sur dix. Quand il faut retirer les calculs, cela passe par une intervention chirurgicale ou par des techniques de fragmentation \u00e0 l\u2019aide d\u2019ondes de choc ou de lasers. Mais les options pour pr\u00e9venir leur formation restent tr\u00e8s limit\u00e9es, et reposent principalement sur une hydratation intensive et des mesures di\u00e9t\u00e9tiques strictes. C\u2019est pourquoi des \u00e9quipes de recherche s\u2019activent \u00e0 d\u00e9velopper de nouvelles approches avant l\u2019apparition des sympt\u00f4mes douloureux. Parmi les pistes explor\u00e9es, celle de la\u00a0th\u00e9rapie microbienne<\/a>. Le principe\u00a0? Introduire dans l\u2019intestin des bact\u00e9ries modifi\u00e9es capables de d\u00e9grader directement la formation d\u2019oxalate de calcium, un compos\u00e9 responsable de la formation de calculs r\u00e9naux. Pour la premi\u00e8re fois, des chercheurs de l\u2019Universit\u00e9 de Stanford et de la soci\u00e9t\u00e9 sp\u00e9cialis\u00e9e en ing\u00e9nierie microbienne Novome Biotechnologies, \u00e0 San Francisco, ont pr\u00e9sent\u00e9 des r\u00e9sultats prometteurs\u2026<\/p>\n
