Abstract Summary.
Hepatic iron overload has been described in chronic hepatitis C as a cofactor affecting
fibrosis progression. Data in patients with chronic hepatitis B infection
are scarce. We investigated hepatic iron deposits and serum iron indices in
205 consecutive patients with hepatitis B and compensated liver disease.
Mean age of the patients was 42.4 ± 12.4 years and 72.5% were males.
Coinfection with hepatitis delta virus (HDV) was present in 8.8%. At least
one of the serum iron indices was elevated in 41.5% of cases. Hepatic iron
deposits were detected in 35.1% of patients, most of them being minimal
(grade I) (59.7%) or mild (grade II) (27.8%). Variables significantly
associated with hepatic iron deposits were male gender (P = 0.001), serum
ferritin (P = 0.008), ?GT (P = 0.05) and alkaline phosphatase (P = 0.05)
levels. By multivariate analysis hepatic iron deposits correlated with
serum ferritin [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.05-1.4,
P = 0.002]. Presence of mild-moderate (grades II and III) hepatic iron
deposits could be excluded with high negative predictive value (90%) when
serum ferritin was within normal values. A significant correlation between
coinfection with HDV and hepatic iron deposits was also found (OR 4.23, 95%
CI 1.52-11.82, P = 0.003). When compared to monoinfected cases, HDV
positive patients had more elevated ?GT (P = 0.03), more advanced fibrosis
and more severe iron deposits (P < 0.0001).
In conclusion, in well-compensated chronic hepatitis B infection, hepatic iron deposits and
elevation of serum iron indices are common, especially in male gender and
in patients coinfected with HDV. As HBV/HDV liver disease is generally more
rapidly progressive than that caused by HBV monoinfection, we speculate
that iron overload may be one of the factors contributing to the severity
of liver disease. |
