Official Title

Composition and Function of Gut Microbiota in Porto-sinusoidal Vascular Disease Associated With Variable Common Immunodeficiency

Brief Summary

      This aim of this study is the evaluation of the gut microbiota imbalance occurrence and its
      characterization in patients with common variable immunodeficiency associated to an
      enteropathy with or without porto-sinusoidal vascular disease.
    

Detailed Description

      Common variable immunodeficiency (CVID) is the most common symptomatic humoral deficiency in
      adults and is accompanied by digestive symptoms. It is associated with intestinal dysbiosis
      and half of the patients exert a clinical digestive disease, called enteropathy. Hepatic
      complications characterized by porto-sinusoidal vascular disease are observed in 10% of the
      CVID patients. This complication is associated with a high morbi-mortality. In our center
      experience and in the literature, clinical occurrence of enteropathy and hepatic disease are
      highly correlated. Considering (i) the anatomical link between the intestinal tractus and the
      portal circulation, (ii) the clinical correlation between enteropathy and the liver disease
      and (iii) the established relation between gut microbiota and alcoholic cirrhosis, we
      speculate that patients whom develop portosinusoidal complications exert a peculiar
      intestinal dysbiosis.

      This study could contribute to a better understanding of the hepatic disease development,
      hence allowing us to suggest novel therapies based on gut microbiota modification.
