Background, In patients with chronic hepatitis C, the histological outcome
of long term phlebotomy is unknown.
Aim. To investigate biochemical and histological findings before and after
phlebotomy in chronic hepatitis C.
Patients. Twenty-four non-haemochromatotic patients with chronic hepatitis
C were treated with long-term phlebotomy alone,
Results. Hepatic iron concentration had decreased in all patients who under
went a second liver biopsy, two years after iron depletion was attained and
maintained. Histological grading score decreased in four patients, was unc
hanged in two, and increased in five. Histological staging score decreased
in two patients, was unchanged in five, and increased in four. Pretreatment
high serum selenium level predicted the reduction of the inflammatory grad
ing score in univariate analysis (p=0.008), while low serum aspartate amino
transferase (p=0.02) and low propeptide of procollagen III (p=0.08) levels
predicted the lack of progression of liver fibrosis. Furthermore, when iron
depletion was reached, significant reductions of serum levels of aminotran
sferase, gamma glutamyl transferase (-47%), propeptide of procollagen ill,
alpha foetoprotein, selenium were observed in 24 patients. No changes in se
rum hepatitis C virus-RNA levels were found.
Conclusions. Phlebotomy alone seems to be efficacious in suppressing progre
ssion of chronic hepatitis C in some patients. Phlebotomy not only induces
iron depletion, but it even modifies serum levels of other trace elements i
nvolved in the balance between oxidant and antioxidant processes.
