Hepatol Res:肝硬化患者脾脏组织的病理结果

2018-05-30 MedSci MedSci原创

在LC患者中,脾脏组织表现为被动充血和血窦扩张,弥漫性alphaSMA表达,胶原纤维沉积,导致了脾脏硬度增加。

研究背景和目的:在肝硬化(LC)患者中,脾脏僵硬度增加。本研究的目的是在LC患者中描述脾脏的病理特征。

研究方法:研究比较了28例肝硬化患者和6例健康对照组的脾脏组织的病理结果。此外,在9例LC患者中,通过横波弹性成像测量脾脏切除术前的脾脏硬度。脾切除术后,检查了脾脏僵硬与病理结果的关系。

研究结果:在肝硬化患者中,脾脏的被动充血较较正常对照更为常见(P < 0.01)。肝硬化患者,鼻窦较正常对照的鼻窦增大(P < 0.01)。在LC患者的脾脏中,观察到弥漫性alphaSMA表达和胶原纤维的沉积。在9例患者的脾脏硬度检查中,窦房的宽度随脾脏的硬度而增加(r = 0.89, P < 0.01)。弥漫性alphaSMA表达的脾脏组织,患者的脾脏硬度高于那些alphaSMA部分表达的患者的脾脏硬度(P = 0.01)。红色髓质中alphaSMA弥漫性表达的LC患者的纤维化程度高于红髓中alphaSMA部分表达的LC患者的肝纤维化程度(P = 0.03)。

研究结论:在LC患者中,脾脏组织表现为被动充血和血窦扩张,弥漫性alphaSMA表达,胶原纤维沉积,导致了脾脏硬度增加。
