Effects of Dietary Iron Reduction Versus Phlebotomy in Patients with
Chronic Hepatitis C: Results from a Randomized, Controlled
Trial on 40 Japanese Patients.

Background and Aim
Iron may play an important role in the pathogenesis
of hepatitis C.
We conducted this randomized, controlled trial
comparing phlebotomy with dietary iron reduction.
Methods
Forty patients with chronic hepatitis C showing serum
ferritin levels of over 150 ng/ml wererandomized to
either group A (low-iron diet for six months) or group B
(phlebotomy biweekly).
Phlebotomy was continued until serum ferritin had reached
20 ng/ml or less.
Results
At enrollment the clinical characteristics of patients
in the two groups were similar.
Serum ALT levels were significantly reduced
in both groups, but the percent change in alanine
aminotransferase (ALT) was larger in group B
(median, -47.1[range, -69.1 to -16.7] %) than in
group A (-24.2 [-72.6 to 15.9] %, p<0.001).
In group A subjects, no correlation wasdetected
between percent change in ALT and clinical
parameters.
In group B subjects, the baseline ALT activity was
significantly correlated with percent change in ALT (p<0.05),
but iron- related parameters were not correlated.
Conclusion
The efficacy of phlebotomy is superior to that of dietary iron
reduction in chronic hepatitis C.
Serum levels of transaminase activities were a better indicator
for phlebotomy thanconventional indices of iron overload.
