Introduction:
Sparse data are available about the effect of therapy methods on antibody levels in patients with liver failure. The aim of this study was to determine serum immunoglobulin concentrations in patients with chronic hepatic failure (CHF), acute- (ALF), or acute-on-chronic liver failure (ACLF) and to evaluate the impact of MARS treatment or liver transplantation (LT) on antibody levels.
Materials And Methods:
We followed ten patients with ALF, twelve with ACLF and 18 with CHF. Eight patients with ALF and seven with ACLF underwent MARS therapy, whereas the rest received LT. 13 healthy volunteers served as controls. Serum antibody concentrations were measured using ELISA-technique.
Results:
Median serum levels of IgA, IgG and IgM were significantly increased in patients with CHF compared to ALF or controls (P<0.02, P<0.01, and P<0.01). IgM and IgG concentrations were also significantly elevated in patients with CHF compared to ACLF (IgM, 3.7 vs. 1 g/L, P<0.001; IgG, 8.7 vs. 3.1 g/L, P=0.004). Immediately after LT a significant decrease of IgA (6.9 vs. 3.1 g/L, P=0.004), IgG (8.7 vs. 5.1 g/L, P=0.02) and IgM (3.7 vs. 1.8 g/L, P=0.001) was detected in patients with CHF and antibody levels further decreased the days after LT reaching levels comparable to healthy individuals. MARS treatment had no apparent effect on the immunoglobulin profile in patients with ALF or ACLF.
Conclusion:
We provide evidence that LT reverses hypergammaglobulinemia in patients suffering from CHF within one day, which could be explained to a reconstituted hepatic antibody clearance, whereas MARS treatment has no immediate effect on immunoglobulin levels.
