To evaluate the changes of shear-wave velocity (Vs) by acoustic radiation force impulse after treatment in chronic hepatitis C.
Eighty-seven patients with chronic hepatitis C were consecutively treated with combinations of interferon (IFN) plus ribavirin (RBV). Vs value (m/s) was measured with acoustic radiation force impulse before treatment, at end of treatment (EOT), 1 year after EOT, and 2 years after EOT.
In patients with a sustained virological response (SVR) (n = 41), Vs significantly decreased at EOT [1.19 (1.07-1.37), P = 0.0004], 1 year after EOT [1.10 (1.00-1.22), P = 0.0001], and 2 years after EOT [1.05 (0.95-1.16), P < 0.0001] compared with baseline [1.27 (1.11-1.49)]. In patients with a relapse (n = 26), Vs did not significantly decrease at EOT [1.23 (1.12-1.55)], 1 year after EOT [1.20 (1.12-1.80)], and 2 years after EOT [1.41 (1.08-2.01)] compared with baseline [1.39 (1.15-1.57)]. In patients with a nonvirological response (n = 20), Vs did not significantly decrease at EOT [1.64 (1.43-2.06)], 1 year after EOT [1.66 (1.30-1.95)], and 2 years after EOT [1.61 (1.36-2.37)] compared with baseline [1.80 (1.54-2.01)]. Among genotype 1 patients, baseline Vs was significantly lower in SVR patients [1.28 (1.04-1.40)] than in non-SVR patients [1.56 (1.20-1.83)] (P = 0.0142).
Reduction of Vs values was shown in SVR patients after IFN-plus-RBV therapy by acoustic radiation force impulse.
评估慢性丙型肝炎患者经治疗后声辐射力脉冲剪切波速度（Vs）的变化。
87例慢性丙型肝炎患者连续接受干扰素（IFN）联合利巴韦林（RBV）治疗。在治疗前、治疗结束时（EOT）、EOT后1年和EOT后2年，采用声辐射力脉冲测量Vs值（m/s）。
获得持续病毒学应答（SVR）的患者（n = 41），与基线水平[1.27（1.11 - 1.49）]相比，EOT时[1.19（1.07 - 1.37），P = 0.0004]、EOT后1年[1.10（1.00 - 1.22），P = 0.0001]及EOT后2年[1.05（0.95 - 1.16），P < 0.0001]时Vs显著降低。复发患者（n = 26），与基线水平[1.39（1.15 - 1.57）]相比，EOT时[1.23（1.12 - 1.55）]、EOT后1年[1.20（1.12 - 1.80）]及EOT后2年[1.41（1.08 - 2.01）]时Vs未显著降低。未获得病毒学应答的患者（n = 20），与基线水平[1.80（1.54 - 2.01）]相比，EOT时[1.64（1.43 - 2.06）]、EOT后1年[1.66（1.30 - 1.95）]及EOT后2年[1.61（1.36 - 2.37）]时Vs未显著降低。在基因1型患者中，SVR患者的基线Vs[1.28（1.04 - 1.40）]显著低于非SVR患者[1.56（1.20 - 1.83）]（P = 0.0142）。
声辐射力脉冲显示，IFN联合RBV治疗后，SVR患者的Vs值降低。
