Effect of rifaximin treatment on IgG content in plasma. Content of IgG heavy (50 kDa) chain in plasma, analyzed by western blot and expressed as percentage of control subjects. Representative images of the blots are shown. CTL, controls; NMHE, patients without MHE; MHE, patients with MHE; 3, 6: patients with MHE after 3 and 6 months of rifaximin treatment. Values significantly different from controls are indicated by *. Values significantly different in patients with MHE compared to NMHE are indicated by α. Values significantly different after vs. before treatment are indicated by β (*/α/β p < 0.05; **/αα/ββ p < 0.01; ***/ααα/βββ p < 0.001)
