The advantage of gastrectomized patients in management of their chronic hepatitis C.

Because the majority of patients with chronic hepatitis C do not respond to interferon, alternative treatments need to be established. Several lines of evidence suggest that iron depletion is beneficial for such patients. Thus, gastrectomized patients with a reduced capacity for iron absorption might have an advantage in treatment of their liver damage over patients with intact gastrointestinal tracts. Four male gastrectomized patients had post-transfusion chronic hepatitis C. The iron load in three patients was adjusted below 10 ng/ml of serum ferritin level by phlebotomy. Subsequent interferon treatment for the four patients without iron load cleared circulating hepatitis C virus RNA in one patient only. However, serum ferritin concentrations were stabilized at low levels without maintenance phlebotomy, and sustained normalization of serum liver enzyme activities was obtained in all four patients. Similar treatments were done for 10 male patients with intact gastrointestinal tracts. The amount of removed iron from these patients was more than that from gastrectomized patients. Interferon also failed to clear circulating hepatitis C virus RNA except in one case. Low ferritin levels and sustained normalization of liver enzymes were seen in three patients. A transient elevation of ferritin levels with low enzyme activities was seen in two patients. Relapsing hepatitis was seen in five of the seven patients who needed maintenance phlebotomy due to a rebound in serum ferritin levels, probably because of active iron absorption from the intestine. Our data suggest that depletion of cytotoxic iron is a key to managing patients with chronic hepatitis C.
