Standard interferon-alpha in combination with ribavirin for hepatitis C patients with advanced liver disease and thrombocytopenia.

BACKGROUND AND AIM

Patients with advanced liver disease due to thrombocytopenia and chronic infection with hepatitis C virus (HCV) are difficult to treat in view of concerns about the efficacy and safety of interferon-based therapy. Nevertheless, antiviral therapy might have a substantial benefit in these patients as it potentially minimizes disease progression and prevents recurrence after liver transplantation. We evaluated the safety, efficacy and tolerability of standard interferon-alpha in an accelerating dose regimen in combination with ribavirin in patients with HCV-induced liver cirrhosis and thrombocytopenia.

PATIENTS

Nine patients (M=8, age: 48.4 +/- 9.9, mean +/- SD) with HCV-related advanced liver disease and thrombocytopenia were prospectively investigated. The Child-Pugh stage was A in six patients and B in three, the MELD score was 11 [6-17] (median [range]). Four patients were interferon naive. HCV-genotype distribution was 1b (n=3), 3a (n=4) and 4 (n=2). The patients received 1-1.5 MU/d standard interferon-a2b with increasing dose regimen and weight-based ribavirin for 48 weeks (genotype 1), or 24 weeks (genotype 3), or until liver transplantation, respectively.

RESULTS

The baseline platelet count was 64.3 +/- 8.7 (G/l, mean +/- SD) and remained remarkably stable during treatment (58.0 +/- 12.4 G/l at week 4, 51.7 +/- 20.5 G/l at week 8, P=0.1). All patients had adverse events such as weight loss, fever and anorexia. Hospitalization because of decompensation or infection was necessary in three patients. Three patients underwent liver transplantation. A virological response on treatment was achieved in eight patients and sustained in three (33.3%) patients.

CONCLUSION

Treatment with standard interferon-alpha2b/ribavirin could be of benefit in patients with advanced liver cirrhosis and thrombocytopenia however, a vigilant monitoring of these high risk patients is mandatory.
