Zusammenfassung

Das intestinale Mikrobiom ist Teil der „Darm-Leber Achse“, die die physiologische Verbindung zwischen Darm und Leber darstellt. Bei der Pathogenese der nicht-alkoholischen Fettlebererkrankung (NAFLD) spielt das intestinale Mikrobiom eine besondere Rolle, da über die Pfortader Botenstoffe aus dem Darm zur Leber gelangen und dort inflammatorische oder metabolische Prozesse beeinflussen. Veränderungen in der Zusammensetzung des intestinalen Mikrobioms wurden bei NAFLD-Patienten auf Phylum-, Familien-, Gattungs- und Speziesebene beschrieben. Die bisherigen Studien weisen darauf hin, dass bei der NAFLD ebenso wie bei Adipositas und Diabetes mellitus Typ 2 eine krankheitsspezifische Signatur im intestinalen Mikrobiom zu finden ist. Das intestinale Mikrobiom stellt mit seinen vielseitigen Angriffspunkten, d. h. der Zusammensetzung, den bakteriellen Stoffwechselprodukten und den immunologischen Effekten ein spannendes Netzwerk dar, das zukünftig für die Diagnostik und Therapie von großem Interesse sein wird. Um die bisherigen Ergebnisse dauerhaft in den klinischen Alltag einzuführen, werden jedoch weitere standardisierte Studien bei NAFLD Patienten benötigt.
