Management of hepatitis C virus infection in the Asia-Pacific region: an update.

The Asia-Pacific region has disparate hepatitis C virus (HCV) epidemiology, with prevalence ranging from 0·1% to 4·7%, and a unique genotype distribution. Genotype 1b dominates in east Asia, whereas in south Asia and southeast Asia genotype 3 dominates, and in Indochina (Vietnam, Cambodia, and Laos), genotype 6 is most common. Often, availability of all-oral direct-acting antivirals (DAAs) is delayed because of differing regulatory requirements. Ideally, for genotype 1 infections, sofosbuvir plus ledipasvir, sofosbuvir plus daclatasvir, or ombitasvir, paritaprevir, and ritonavir plus dasabuvir are suitable. Asunaprevir plus daclatasvir is appropriate for compensated genotype 1b HCV if baseline NS5A mutations are absent. For genotype 3 infections, sofosbuvir plus daclatasvir for 24 weeks or sofosbuvir, daclatasvir, and ribavirin for 12 weeks are the optimal oral therapies, particularly for patients with cirrhosis and those who are treatment experienced, whereas sofosbuvir, pegylated interferon, and ribavirin for 12 weeks is an alternative regimen. For genotype 6, sofosbuvir plus pegylated interferon and ribavirin, sofosbuvir plus ledipasvir, or sofosbuvir plus ribavirin for 12 weeks are all suitable. Pegylated interferon plus ribavirin has been replaced by sofosbuvir plus pegylated interferon and ribavirin, and all-oral therapies where available, but cost and affordability remain a major issue because of the absence of universal health coverage. Few patients have been treated because of multiple barriers to accessing care. HCV in the Asia-Pacific region is challenging because of the disparate epidemiology, poor access to all-oral therapy because of availability, cost, or regulatory licensing. Until these problems are addressed, the burden of disease is likely to remain high.

Influence of the sorafenib patients assistance program on treatment compliance and overall survival of unresectable hepatocellular carcinoma patients.

AIM: to evaluate treatment compliance and survival of patients receiving oral sorafenib in Indonesia. METHODS: a prospective cohort trial. Unresectable Hepatocelullar carcinoma patients receiving Sorafenib in NexPAP program were recruited between October 2008 and September 2011. A historical cohort from Cipto Mangunkusumo Hospital, between 1998 and 2000 was selected to serve as control group. Patients in the control group received symptomatic treatment. Survival analysis was done by the Kaplan-Meier survival curve analysis and the log-rank test. Median survival difference between the NexPAP and control group was tested using the Cox-regression hazard analysis. RESULTS: There were 48 patients in the NexPAP group and 40 patients in the control group. Treatment compliance was very good; no patient with drew from the study. Sorafenib generally could be tolerated by the patients. The most common adverse events are mild or moderate hand and foot skin reaction and diarrhea. The median survival was 49 weeks in NexPAP group (95% CI 37.9-60.1) vs. 20 weeks in the control group (95% CI 9.0-31.0). Cox-regression analysis showed that sorafenib significantly prolonged overall survival with a hazard ratio (HR) of 0.339 (95% CI: 0.196-0.584). There was no survival difference between patients with Child-Pugh class A and class B in both NexPAP (median 49 vs. 52 weeks; HR 1.1; 95% CI 0.5-2.3; p=0.855) and control groups (27 vs. 20 weeks; HR 1.1; 95% CI 0.5-2.4; p=0.822). CONCLUSION: Sorafenib patient assistant program in unresectable hepatocellular carcinoma ensured compliance treatment and significantly prolonged overall survival over the historical cohort receiving palliative treatment.
