Poster 341: EFFICACY OF LONG-TERM DIETARY IRON RESTRICTION IN PATIENTS
WITH CHRONIC HEPATITIS C

Objectives
It is important to maintain reduced serum alanine aminotransferase
(ALT) levels in cases with chronic hepatitis C (CH-C) that do not
respond to interferon (IFN) and in those with no indication of IFN
therapy. We reported previously that dietary restriction of iron intake
reduces serum ALT levels in such patients. We evaluated CH-C patients
treated with iron-restricted diet for two or more consecutive years,
mainly focusing on the balance of energy intake, physical examination,
and changes in hematological indices of nutrition.
Methods
Twenty-two patients with CH-C (males, 18; females, 4; mean age, 56
year-old) that consulted our outpatient department were enrolled in
this study. The inclusion criteria were as follows: 1) elevation of ALT
levels above the upper normal limit for 3 months or more; 2) positive
tests for HCV-antibody and HCV-RNA; 3) absence of other causes of CH
(alcoholic liver disease, drug-induced liver injury, hemochromatosis)
and negativity for hepatitis B surface antigen and for serum
anti-nuclear and anti-mitochondrial autoantibodies. Twenty cases had
received IFN therapy for more than 12 months before the beginning of
the study; none of them responded to IFN therapy. Dietary prescriptions
included iron intake 7 mg/day or less, energy intake 30 kcal/kg/day,
protein intake 1.1-1.2 g/kg/day, and a fat energy fraction of 20%.
Nutritional balance was evaluated based on meal records, and
instructions was given when necessary.
Results
The average energy intake before dietary prescription was 2184 kcal
(36.7 kcal/kg)/day, and it was significantly reduced to 1655 kcal (28.5
kcal/kg)/day (p < 0.01), and then maintained stable at 30 kcal/kg/day.
The average protein intake before dietary prescription was 85.7 g (1.45
g/kg)/day and it was reduced to 1.1-1.2 g/kg/day after the
prescription. The average fat intake of 66.5 g (1.1 g/kg)/day and the
average fat energy fraction of 27% before the dietary prescription were
significantly decreased to 30.8 g (0.52 g/kg)/day; p < 0.01 and 16% (p
< 0.001), respectively, after dietary instructions. The fat energy
fraction was maintained at a level of 20% or less. Carbohydrate intake
did not change remarkably during the observation period, although the
carbohydrate energy fraction significantly (p < 0.001) increased. The
average iron intake decreased significantly (p < 0.001) from 9.6
(before) to 6.1, 5.2, 5.1, 5.2, and 5.1 mg/day 6, 12, 18, and 24 months
after dietary prescription, respectively. Body mass index (BMI) before
diet prescription was 23.9 on average; BMI had no significant change
throughout the course. The body fat percentage was 24.6% on average
before the diet instructions, and it significantly decreased after the
diet. The average values of aspartate aminotransferase and ALT before
diet prescription were 65 IU/l and 66 IU/l, respectively, and they were
significantly reduced to 48 IU/l and 49 IU/l, respectively, after 24
months (p < 0.01). Serum iron levels significantly decreased after 18
(p < 0.01) and 24 (p < 0.05) months, while unsaturated iron binding
capacity tended to increase. The average serum ferritin levels were
376, 210, 189, 189, 141 ng/ml before and 6, 12, 18, and 24 months after
diet, respectively; there was a significant reduction (p < 0.01) in the
values measured before and after the diet instructions. The average
levels of hemoglobin, albumin and cholinesterase did not change
significantly during the follow-up period.
Conclusions
Restriction of iron intake is safe and well tolerated for a long
period. The results of our present study suggest that decreased dietary
intake of iron may constitute an important adjuvant therapy in patients
with CH-C.

Are you referring to the virus known as Hepatitis C when you say "HC is
a genetic disease"?
If you are referring to Hepatitis C (Hep C or HCV) when you use the
term HC I repeat my question: when did Hepatitis C become genetic?
IronJustice made the initial post. His reference was to Hepatitis C
Virus, variously known as HCV, or Hep C.
Whatever we call it, it is not called genetic.
Please clarify.
