Purpose/Aim
Results of treatment of chronic hepatitis C (CHC) with pegylated interferon plus ribavirin (PEG-RBV) are mainly available from well-designed clinical trials, and only few ‘real-life’ studies which give a true picture of success of therapy are available. Such data in Indian patients is scarce. This prospective study aimed to evaluate the efficacy, safety, and factors associated with sustained virological response (SVR) in Indian CHC patients treated with PEG-RBV in ‘real-life’ setting.
Material and Methods
All treatment-naïve patients with CHC/compensated cirrhosis treated with PEG-RBV between January 2004 and December 2010 were included.
Results
Of 592 patients started on treatment, 524 (88.5 %) completed therapy (mean ± SD age—42.0 ± 12.1 years; 74.3 % males). Genotype 3 (73.6 %) was the commonest, followed by genotype 1 (19.3 %). In intention to treat analysis, SVR rates for ‘all’ patients, genotype 1 and genotype 3 patients were 72.3 % (428/592), 57 % (65/114), and 78.2 % (341/436), respectively (in per-protocol analysis—81.7 %, 69.1 %, and 85.3 %, respectively). Noncirrhotics had better SVR rates compared to cirrhotics treated for the same duration. About 20 % patients had both low viral load and achieved rapid virological response (RVR). Factors significantly associated with SVR were age <40 years, absence of cirrhosis, RVR, and no reduction in interferon dose.
Conclusion
SVR rates in CHC patients treated in ‘real-life’ setting in India were better than those reported in western population. Therapy should be prolonged for patients with cirrhosis, while one-fifth of patients may qualify for abbreviated therapy. Factors significantly associated with SVR were age <40 years, absence of cirrhosis, RVR, and no reduction in interferon dose.
