*Purpose: In the European multicentre “ChilSFree” study we aimed to identify soluble and cellular biomarkers in blood of various end-stage diseases before pLTx.

*Methods: Using flow cytometry-based immunophenotyping, and protein multiplex (50-plex) array we defined cellular and soluble immune characteristics of 10 major end-stage diseases before pLTx (n>153).

*Results: The Alagille syndrome showed the highest count of almost all immune cells: CD3+T cells, CD19+B cells, CD56+NK cells, granulocytes and monocytes as well as higher plasma concentrations of CXCL10, CCL4, PDGF-b, FGF, IL-13, IL-9. Hepatic malignancy was demarcated by the highest ratio of CD3+T cells, comprising nearly 90% of all lymphocytes in these patients as well as increased monocytes ratio, while acute liver failure was defined by the altered CD4+/CD8+ T cell ratio and higher counts of granulocytes and monocytes and CXCL10 and HGF plasma levels. The immune profile of biliary atresia was dominated by granulocytes and monocytes as well as higher CXCL1, HGF, CXCL8 and CCL4.

*Conclusions: We provide here soluble and cellular blood immune characteristics of major end stage diseases before pLTx, which may pave the way to improved therapeutic options.
