Antiviral therapy of decompensated cirrhosis due to hepatitis C viral infection.
BACKGROUND
For decompensated HCV cirrhosis, liver transplantation is the only available treatment. Only a few studies in world literature have used antiviral therapy in this situation.


METHODS
During a 4-year period, we gave closely monitored antiviral therapy to all consecutive patients of HCV-related cirrhosis with episodes of decompensation. Patients who were excluded from the standard Interferon trials were treated. Patients were started on low dose Interferon alpha-2b (1 MIU tiw) and Ribavirin (800 mg/day) combination therapy or low-dose Interferon alpha- 2b (1 MIJ tiw) monotherapy (in the presence of renal failure) for 6 months to 1 year. Dose of Interferon was escalated gradually to a maximum dose of 3 MIU tiw according to clinical follow-up.


RESULTS
A total of 18 patients (mean age = 51.6 +/- 9.8 years; male: female ratio= 10: 8) were treated. At baseline, mean Child-Pugh score was 9.4 +/- 0.8 (range = 7-12). Interferon monotherapy was given to 4 (22.2%) and combination therapy to 14 (77.8%) patients after clinical recovery from an episode of decompensation. Though 16 (88.9%) patients noticed some adverse events, 15 (83.3%) patients completed the treatment schedule. Premature discontinuation was warranted in 3 (16.7%) patients. Out of the 15 patients who completed the treatment schedule, mean maximum tolerated dose of Interferon was 1.73 +/- 0.6 MIU tiw, 10 patients had genotype II or III and 2 patients had genotype I. Of these, end-of-treatment virological response was seen in 11 (73.3 %) and sustained virological response (at 6 months) in 7 (46.6 %) patients. All these patients were followed up for a mean duration of 1.3 +/- 0.6 years (6 month to 3.5 years). During follow up, 7 non-responders had further episodes of decompensation, of whom 4 died.


CONCLUSIONS
Although there is high intolerance to the treatment, closely-monitored low dose escalating Interferon and/ or Ribavirin therapy achieves good results.
