AB This study was performed in patients with hepatitis C virus (HCV) who
were treated with hemodialysis to determine the relationships among
alanine amino-transferase (ALT) levels, immunoglobulin (Ig) G anti-HCV,
IgM anti-HCV core, and HCV RNA. Of 107 patients on hemodialysis, 27 had
positive IgG anti-HCV. Eight of the patients who had HCV were evaluated
every 8 months during a period of 2 years, using the following selection
criteria: positive IgG against c-22, c33-c, 5-1-1, and c100-3 viral
peptides; absence of infection by hepatitis A virus, hepatitis B virus,
cytomegalo-virus, Epstein-Barr virus, herpes simplex virus, and human
immunodeficiency virus, as well as absence of hepatotoxic drugs or
cholelithiasis. We considered elevated ALT values as those more than
150% of the upper limit of normal. Three of the patients had persistent
elevation of ALT levels, two had alternating elevation of ALT levels,
and three had normal ALT levels in all blood samples. Of the 24 blood
samples, 11 had elevation of ALT (45.8%) levels that showed positive IgM
anti-HCV, but only 7 of these 11 had positive HCV RNA (63.6%). None of
the 13 blood samples without elevation of ALT had positive IgM anti-HCV,
but 5 had positive HCV RNA (38.5%). We found an excellent correlation
between IgM anti-HCV and ALT levels (r = 0.81). There was no
statistically significant difference between the mean ALT values on the
12 blood samples that had positive HCV RNA and the mean ALT values of
the negative HCV RNA samples (53.5 +/- 28.0 IU/l vs. 37.4 +/- 17.5 IU/l,
respectively). IgM anti-HCV is related to the elevation of ALT levels
and can be used as a serologic marker to indicate the presence of active
HCV induced liver damage. Serum ALT levels do not correlate with the
detection of viral genome in sera. IgG anti-HCV is not necessarily
associated with HCV RNA or IgM anti-HCV. The absence of IgM and HCV RNA
in patients with IgG anti-HCV and normal ALT levels does not necessarily
suggest the absence of active HCV infection.
