Development of a Predictive Score for the Risk of Infection in the Immediate Post-liver-transplant Period (PREDITH)
Liver transplantation (LT) is the only curative treatment option for patients with severe liver disease. Since 2007, the implementation of the MELD score in liver transplant allocation guidelines has led to a change in the profile of transplant recipients, notably with an increase in the proportion of patients receiving transplants for severe liver failure. Thus, in 2023, nearly 40% of liver transplant recipients whose primary indication for LT was cirrhosis had a MELD score greater than 35 (ABM Scientific Report 2023). These patients with severe pre-transplant liver failure often present with associated organ failure (Acute-on-Chronic Liver Failure, ACLF). Infections are the leading cause of death at 1 year post-transplant for patients transplanted with ACLF and are a major concern for all patients, representing one of the leading causes of death at 3 months post-transplant. Another common complication following LT is acute cellular rejection. Although frequent, this complication is reversible with treatment and results in graft loss in fewer than 5% of cases.
The expression of the HLA-DR marker by monocytes (mHLA-DR) is correlated with immunoparesis and the risk of secondary infection and mortality in patients admitted to critical care. In a prospective, single-center pilot study of 99 liver transplant recipients, the Hepatology and Gastroenterology service at the Croix Rousse Hospital, Hospices Civils de Lyon, demonstrated that the kinetics of mHLA-DR levels measured immediately after transplantation could predict the risk of early significant infection (< 1 month) after transplantation and 1-year post-transplant mortality. The early post-transplant kinetics of mHLA-DR expression recovery appeared to be a more relevant predictor of the risk of early post-transplant infection than a single-point-in-time value. The profile of immune recovery kinetics, as well as a pre-LT MELD score > 30, were associated in multivariate analysis with the risk of developing an infection at 1 month post-LT and with 1-year post-LT survival.
PREDITH study team hypothesize that the implementation of mHLA-DR testing immediately post-LT would enable the development of a predictive score for early post-LT infection combining clinical and biological risk factors for post-LT infection and immune monitoring.

Patients with severe liver disease waiting for liver transplantation
Only patients with the most frequent LT indications will be eligible: complicated cirrhosis of hepatocellular carcinoma (HCC), acute or chronic decompensation of cirrhosis, with or without multi-visceral and fulminant hepatitis
|
Samples will be collected at the finale inclusion of the day oh the LT, including one sample of Cyto-Chex BCT (4 millilitre mL) .
Same samples will also be collected after LT at days 1,3,5 and 10.
Biological data will be collected at those different times
For the creation of the biobank one samples of Ethylenediaminetetraacetic acid (EDTA) (4 millilitre (mL)), and one PAXgene® sample (2.5mL) will be collected:

Predictive score for the risk of infectious complications
Zeitfenster: Day 30
|
The primary endpoint will be the sensitivity and specificity of a predictive score for the risk of early post-Liver Transplant (LT) infectious complications (30 days post-LT) in a population of patients undergoing LT for standard indications (cirrhosis complicated by HCC, decompensated cirrhosis, acute hepatitis).
The predictive score will be based on baseline (Day 0), Day 1, Day 3, Day 5, and Day 10 mHLA-DR levels, the pre-LTP MELD score, and/or other clinical or laboratory parameters significantly associated with the risk of infection.
