Primary Outcome Measures:
  • The prevalence of infra clinical liver injuries [ Time Frame: At least one day depending on the schedule of the exams ] [ Designated as safety issue: No ]
    The prevalence of infra clinical liver injuries (lesions or liver abnormalities) in a cohort of adult patients presenting an Alpha-1 AT deficiency. Suspicion of fibrosis was defined as liver stiffness > 7.2kPa measured by transient elastography (TE).

Secondary Outcome Measures:
  • morphological liver complications description [ Time Frame: At least one day depending on the schedule of the exams ] [ Designated as safety issue: No ]
    To describe all the morphological liver complications present at the moment of the investigation.

  • measure of biological parameters [ Time Frame: At least one day depending on the schedule of the exams ] [ Designated as safety issue: No ]
    - To measure the biological parameters (as AST, ALT, GGT, total bilirubin, lymphocytes, platelets, FibroTest score) and radiological aspects (TE score, liver aspect evaluated by ultrasound)
