L. Cimino et al., EFFECT OF N-ACETYL-CYSTEINE ON LYMPHOMONOCYTE GLUTATHIONE AND RESPONSE TO INTERFERON TREATMENT IN C-VIRUS CHRONIC HEPATITIS, The Italian Journal of Gastroenterology, 30(2), 1998, pp. 189-193
Background/aim. Much controversy exists concerning effect of N-acetyl-
cysteine, a precursor of glutathione, on the response to interferon tr
eatment in patients with C-virus chronic hepatitis. The aim of this st
udy was to evaluate the efficacy of interferon therapy with and withou
t oral N-acetylcysteine. We also measured glutathione concentrations i
n lymphomonocytes of 25 patients with chronic C-virus hepatitis before
and after interferon treatment and correlated the results with treatm
ent response. Methods, Glutathione was extracted from lymphomonocytes
and measured with a modified high performance liquid chromatographic m
ethod in the 25 hepatitis patients and 12 healthy controls. Results/Co
nclusions. 1) Hepatitis patients and controls had similar basal concen
trations of lymphomonocytic glutathione; 2) neither interferon nor N-a
cetyl-cysteine significantly affected glutathione concentrations in pa
tients; and 3) N-acetyl-cysteine did not affect response to interferon
.
