QU’EST-CE QUE L’INSUFFISANCE R\u00c9NALE CHRONIQUE ?<\/span><\/h2>\n
\n

L\u2019insuffisance r\u00e9nale\u00a0chronique<\/span>\u00a0est la diminution progressive et irr\u00e9versible de la capacit\u00e9 des reins \u00e0 assurer leurs fonctions de filtration du sang, de r\u00e9gulation de sa composition et de s\u00e9cr\u00e9tion d\u2019hormones<\/span>. Cette lente d\u00e9t\u00e9rioration du fonctionnement des reins conduit \u00e0 diverses complications, dont l\u2019accumulation des d\u00e9chets du\u00a0m\u00e9tabolisme<\/span>\u00a0et de l\u2019eau, l\u2019an\u00e9mie<\/span>\u00a0et les troubles cardiovasculaires. L\u2019insuffisance r\u00e9nale\u00a0chronique<\/span>\u00a0est le plus souvent la cons\u00e9quence d\u2019une autre maladie, en particulier du\u00a0diab\u00e8te<\/span>\u00a0et de l\u2019hypertension art\u00e9rielle<\/span>.<\/p>\n

L’INSUFFISANCE R\u00c9NALE CHRONIQUE EST-ELLE FR\u00c9QUENTE\u00a0?<\/span><\/h2>\n

Aujourd\u2019hui, entre 1,7 et 2,5\u00a0millions de Fran\u00e7ais sont concern\u00e9s par une\u00a0insuffisance r\u00e9nale<\/span>\u00a0l\u00e9g\u00e8re, mod\u00e9r\u00e9e ou s\u00e9v\u00e8re. L\u2019\u00e2ge moyen au moment du\u00a0diagnostic<\/span>\u00a0est de 59 ans. Pour 71\u00a0000 patients, ceux dont les reins sont d\u00e9truits \u00e0 plus de 85 % (stade dit \u00ab\u00a0d\u2019insuffisance r\u00e9nale<\/span>\u00a0terminale<\/b>\u00a0\u00bb), le recours \u00e0 la\u00a0dialyse<\/span>\u00a0(\u00ab rein artificiel \u00bb) ou \u00e0 la greffe de rein est n\u00e9cessaire. On estime que, chaque ann\u00e9e, environ 4\u00a0000 personnes d\u00e9butent un traitement par\u00a0dialyse<\/span>\u00a0et 3\u00a0000 re\u00e7oivent une greffe de rein.<\/p>\n

\u00c0 quoi servent les reins\u00a0?<\/span><\/th>\n<\/tr>\n
Les reins contiennent plus d\u2019un million de canaux microscopiques, les\u00a0n\u00e9phrons<\/b>, eux-m\u00eames compos\u00e9s d\u2019un\u00a0glom\u00e9rule<\/b>\u00a0et d\u2019un\u00a0tubule<\/b>\u00a0connect\u00e9s aux canaux qui collectent l\u2019urine. Les reins assurent trois fonctions dans notre corps.<\/p>\n
    \n
  • Ils filtrent le sang et produisent l\u2019urine<\/b>. Chaque glom\u00e9rule est un filtre qui retient les cellules et les grosses prot\u00e9ines du sang, mais laisse passer l\u2019eau, les\u00a0sels<\/span>\u00a0min\u00e9raux et les petites mol\u00e9cules. Situ\u00e9 en aval, le tubule r\u00e9absorbe les substances dont le corps a besoin et laisse partir dans l\u2019urine les d\u00e9chets issus du\u00a0m\u00e9tabolisme<\/span>\u00a0(ur\u00e9e<\/span>,\u00a0acide urique<\/span>,\u00a0cr\u00e9atinine<\/span>, etc.) ou substances en surplus (eau,\u00a0sels<\/span>\u00a0min\u00e9raux, etc.).<\/li>\n
  • Les reins r\u00e9gulent la quantit\u00e9 d\u2019eau pr\u00e9sente dans le corps, ainsi que la concentration de divers\u00a0sels<\/span>\u00a0min\u00e9raux<\/b>\u00a0(sodium<\/span>,\u00a0potassium<\/span>, calcium, phosphore, par exemple) dans le sang.<\/li>\n
  • Enfin,\u00a0les reins s\u00e9cr\u00e8tent diverses\u00a0hormones<\/span><\/b>\u00a0: la\u00a0r\u00e9nine<\/b>\u00a0qui participe au contr\u00f4le de la\u00a0pression art\u00e9rielle<\/span>, l\u2019\u00e9rythropo\u00ef\u00e9tine<\/span><\/b>\u00a0qui stimule la production de\u00a0globules rouges<\/span>, et le\u00a0calcitriol<\/b>, forme active de la\u00a0vitamine<\/span>\u00a0D, qui r\u00e9gule le\u00a0m\u00e9tabolisme<\/span>\u00a0du calcium dans le corps.<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
