Influence of esophageal variceal bleeding on iron status in chronic hepatitis C patients.

BACKGROUND

Disorders of serum iron balance are frequently observed in chronic hepatitis C (CHC) patients. Iron overload as well as iron deficiency anemia are common clinical findings in these patients. Variceal bleeding is also a common complication. To date, no study has discussed the influence of esophageal bleeding on iron status in anemic CHC bleeders.

OBJECTIVE

Was to study reticulocyte hemoglobin content (CHr) and serum hepcidin levels in anemic CHC and to evaluate the influence of variceal bleeding on patients' iron status.

METHODS

Serum hepcidin levels and CHr were assessed in 65 early phase CHC patients (20 nonanemic, 23 anemic nonbleeders, and 22 anemic bleeders), and 20 healthy controls; and were compared with the conventional indices of iron deficiency including mean corpuscular volume, mean corpuscular hemoglobin, red cell distribution width, serum iron, total iron binding capacity, transferrin saturation and ferritin.

RESULTS

Hepcidin levels were comparable in patients groups, but were significantly lower in patients than in controls (P = 0.01). Child-Pugh class B patients showed significantly lower hepcidin levels than class A patients. CHr levels were comparable in all groups as well as all iron deficiency indices. Patients with ferritin values or less 100 ng/ml and CHr or less 29 pg/cell or Tfsat or less 16% are more likely to have iron deficiency [odds ratio (OR = 3.93, 95% confidence interval (CI) = 2.54-6.08; OR  = 10.50, 95% CI = 1.94-56.55, respectively).

CONCLUSION

Esophageal bleeding has an almost no influence on iron status in CHC patients. Serum hepcidin content is influenced by CHC disease rather than by anemia associated with or without esophageal bleeding and it could be used as a marker of early hepatic insufficiency. Assessing CHr content could add a potential utility in the detection of iron deficiency in CHC patients.
