Efficacy and safety of 6-month iron reduction therapy in patients with hepatitis C virus-related cirrhosis: a pilot study

Background Iron reduction therapy (IRT) has been recognized as beneficial for chronic hepatitis C patients. However, its efficacy for hepatitis C virus-related liver cirrhosis (LC-C) has not been elucidated. We evaluated the efficacy and safety of IRT for LC-C patients. Methods Twenty-two LC-C patients were treated with biweekly phlebotomy and low iron diet for 6 months, in addition to regular hepatoprotective therapy. Nineteen sex- and age-matched patients who refused to receive IRT were used as controls. The efficacy of IRT was evaluated on the basis of biochemical parameters. Results Of 22 patients receiving IRT, 19 completed the 6-month treatment. IRT significantly reduced serum levels of aspartate aminotransferase (from 89 to 57 U/L; P = 0.003), alanine aminotransferase (from 101 to 54 U/L; P < 0.001), and α-fetoprotein (from 28 to 12 ng/mL; P = 0.003). These changes were not observed in the controls. Two patients whose serum albumin concentrations were less than 3.6 g/dL at the beginning of IRT withdrew from IRT because of the new appearance of ascites. Conclusions IRT improved the serum levels of aminotransferases and α-fetoprotein in LC-C patients and was generally safe; however, IRT should be performed in patients who maintain serum albumin concentrations of more than 3.6 g/dL.     

Granulocyte colony-stimulating factor-supported combined immunosuppressive therapy (antilymphocyte globulin, cyclosporine, and methylprednisolone) in patients with aplastic anemia: tolerability, efficacy, and changes in the progenitor cell compartment

 Neutropenic infections are the major cause of morbidity and mortality in the treatment of aplastic anemia (AA) with antilymphocyte globulin (ALG), cyclosporin A (CSA), and methylprednisolone (MP). Recent data suggest a beneficial effect of administering G-CSF as an adjunct to immunosuppression. We have treated 11 consecutive patients with AA using a combined immunosuppressive regimen including ALG, CSA, and MP plus G-CSF at a dose of 5 μg/kg/day until neutropoietic recovery. In addition to measuring routine hematological parameters we have performed serial determinations of reticulocyte counts and in vitro progenitor cell cultures before and after therapy in order to assess their predictive value for treatment response and to determine the impact of therapy on early hematopoiesis. One patient died on day 34 of neutropenic septicemia. At 1 year, 81% of patients showed response to treatment. The median time to ANC values >0.5 and >1.0×10⁹/l were 19 and 35 days, respectively. Reticulocyte counts started to recover after 6 weeks, and transfusion independence was observed on day 52 for red blood cell transfusions and on day 53 for platelet concentrates. All patients with detectable colony formation in peripheral blood achieved a complete hematological remission, as compared with only one of five patients without progenitor cell growth. Although normal ranges were rarely achieved, there was a small but definitive improvement in progenitor cell numbers as compared with baseline values in most patients. Our results confirm the good tolerability and high efficacy of this G-CSF-supported combined immunosuppressive therapy for AA. Detectable colony growth at diagnosis seems to predict a high chance for complete hematological response. Received: July 2, 1998 / Accepted: March 3, 1999
