摘要: 目的探讨普通人群肝脏硬度测量值(LSM)与受控衰减参数(CAP)之间的关联,为临床研究提供参考。方法在207例成功进行FibroScan检查的健康体检者,获取性别、年龄、体质量指数(BMI)和腰高比(WHtR)资料,分析其LSM和CAP的相关性。结果不同年龄人群LSM的差异无统计学意义,但在BMI≥24 kg/㎡的受试者,其LSM和CAP值分别为(4.60±1.15) kPa和(245.24±55.37) dB/m,均显著高于BMI<24 kg/㎡的受试者[(4.25±1.23) kPa和(215.82±55.47) dB/m,P<0.001];WHtR≥0.50的受试者LSM和CAP分别为(4.52±1.22) kPa和(247.04±57.78)dB/m,亦均高于WHtR<0.50的受试者[(4.19±1.15) kPa和(204.65±52.25) dB/m,P<0.05];男性受试者LSM和CAP值亦均高于女性受试者[(4.53±1.23) kPa和(4.11±1.08) dB/m对(4.11±1.08) kPa和(220.08±57.88) dB/m,P<0.05];年龄≥50岁的受试者CAP值[(246.56±59.06) dB/m]高于年龄<50岁的受试者[(222.88±56.60) dB/m];LSM与CAP值呈显著性正相关(r=0.26,P=0.0002);进一步对各组人群分析发现,在BMI≥24 kg/㎡、WHtR>0.50、男性受试者和年龄≥50岁的受试者中,LSM与CAP值呈显著性正相关(P<0.05),其中在BMI≥24 kg/㎡组人群,两者呈非常显著性正相关(r=0.37,P<0.01);通过相关分析发现,LSM和CAP均与BMI、WHtR和性别相关(P<0.05);通过偏相关分析发现,LSM与CAP参数之间呈显著性正相关(r=0.20,P=0.0045);在体质量指数≥24 kg/㎡的超重或肥胖的受试者中,肝脏硬度值和受控衰减参数的相关性更强(r=0.37,P=0.0003)。结论普通人群LSM与CAP均受BMI、WHtR和性别的影响,并且两个参数之间表现出一定的正相关,其相关存在的确切原因有待于进一步研究。

Abstract: Objective To explore the correlation between liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) in the general population. Methods A correlation of LSM to CAP was conducted in a total of 207 participants who were successfully examined by FibroScan in a general health examination,and the data including gender,age,body mass index(BMI) and waist height radio (WHtR) were recorded. Results The LSM and CAP in overweight and obese participants (BMI≥24 kg/m2) were higher than those in lean participants (BMI<24 kg/m2) [(4.60±1.15)kPa vs. (4.25±1.23)kPa,P<0.001 and (245.24±55.37) dB/m vs.(215.82±55.47) dB/m,P<0.001];participants with WHtR≥0.50 had higher LSM and CAP as compared to those with WHtR<0.50 [(4.52±1.22) kPa vs.(4.19±1.15) kPa,P<0.05 and(247.04±57.78) dB/m vs.(204.65±52.25) dB/m,P<0.05];male participants had higher LSM and CAP than in female [(4.53±1.23)kPa vs.(4.11±1.08) kPa,P<0.05 and (4.11±1.08) dB/m vs.(220.08±57.88) dB/m,P<0.05]; the CAP was higher in participants older than 50 years as compared to participants under 50 years[(246.56±59.06)dB/m vs.(222.88±56.60) dB/m,P<0.01],while the LSM in the two groups showed no difference(P>0.05);The LSM was significantly correlated with CAP in this cohort(r=0.26,P=0.0002);Further analysis demonstrated that CAP was correlated with LSM in male,older than or equal to 50 years,
