Abstract | OBJECTIVE: METHODS: Patients were pretreated with PSE and then received triple combination therapy. The safety and efficacy of PSE was evaluated. RESULTS: Eighteen patients were analyzed, including 12 patients with the interleukin 28B (IL28B) major genotype and 12 patients with the inosine triphosphatase (ITPA) major genotype. The median embolization rate with PSE was 70% (range: 40-85%). PSE increased the patients' platelet counts from 71.5×10(3) /μL (53-99×10(3) /μL) to 121.5×10(3) /μL (70-194×10(3) /μL; p=0.0002). The patients' platelet counts fluctuated above 50×10(3) /μL during the treatment. Specifically, the increase in the platelet count was significantly associated with the ITPA major genotype compared with the minor genotype (p=0.0057 at 2 weeks, p=0.0031 at 3 weeks, and p=0.0148 at 4 weeks). Adherence to peg-IFN-α2b was sufficient (1.38 μg/kg/week). The rapid viral response rate was 72.2% (13/18), the end of treatment response rate was 88.9% (16/18), and the sustained virological response (SVR) rate was 66.7% (12/18). The SVR rate for patients with the IL28B major genotype was 83.3% (10/12). No adverse effect due to PSE pretreatment was found in any patients. Furthermore, no patient discontinued treatment due to thrombocytopenia. CONCLUSION:
