In an open study
the clinical efficacy of milk serum (whey) protein (Immunocal;
cysteine content: 7.6-fold higher than that of casein)
isolated from fresh milk and purified without heating
was evaluated in 25 patients with chronic hepatitis B
or C. Immunocal (12 g as protein) food (mousse) was given
twice a day, in the morning and evening, for 12 weeks
(test period). Casein (12 g as protein) food (mousse)
was similarly given for two weeks prior to the start
of the supplement with Immunocal food (induction period)
and for four weeks after the end of the supplement with
Immunocal food (follow-up period). Serum alanine aminotransferase
(ALT) activity was reduced, and plasma glutathione (GSH)
levels increased in six and five of eight patients with
chronic hepatitis B, respectively, 12 weeks after the
start of the supplement with Immunocal food. Serum lipid
peroxide levels significantly decreased, and interleukin
(IL)-2 levels and natural killer (NK) activity significantly
increased. However, there were no significant Immunocal-related
changes in 17 patients with chronic hepatitis C. These
findings suggest that the long-term supplement with Immunocal
alone may be effective for improving liver dysfunctions
in patients with chronic hepatitis B.
