Conditions

Liver Cirrhosis

Brief summary

Individuals with metabolic syndrome (MetS), particularly those with type 2 diabetes (T2D), and/or metabolic dysfunction-associated steatohepatitis or MASH face an elevated risk of major cardiovascular events (MACE). We showed decrease plams level of PPi in patients with liver cirrhosis. We hypothezised that liver transplant should block AC and restore PPi plasma level.

Interventions

OTHERa blood test and urine sample collection.

The study is offered to all patients who meet the inclusion criteria during their pre-transplant assessment by the principal investigator (during an existing visit). Patients eligible for HT are contacted by a clinical research coordinator, and if they agree, an inclusion visit is arranged.
