Abstract

Background and Aims

Transjugular intrahepatic portosystemic shunt (TIPS) has been demonstrated to be feasible in older adult patients (age ≥70 years), yet the selection criteria remain suboptimal. Sarcopenia, highly prevalent in elderly population, may be significantly associated with post-TIPS outcome. This study aimed at evaluating the impact of baseline sarcopenia on post-TIPS survival in older adults with cirrhosis.

Method

A retrospective analysis of the prospective Italian TIPS-Registry was conducted to identify patients ≥70 years who received TIPS from June 2015 to March 2023. The availability of baseline abdominal CT scan was a mandatory inclusion criterion. Skeletal muscle index (SMI) was evaluated at the L3-L4 level. Sarcopenia was defined as SMI <50 cm²/m² for men and <39 cm²/m² for women. Probability of liver-related death was evaluated by competing risks analysis. A prediction model for liver-related mortality was created.

Results

One-hundred and fifteen patients were included: median age 74 years (IQR 3.1), 62% male, median dry-BMI 25.7 (IQR 4.7), 60% prevalence of sarcopenia. The main etiologies were viral (40%), alcohol-associated cirrhosis (23%), and metabolic dysfunction-associated steatohepatitis (20%). Refractory ascites (57%) was the main indications for TIPS. During a mean follow up of 20 months (IQR 20), 40 (34.8%) patients died for liver-related causes and 16 (13.9%) for extrahepatic causes. Liver-related mortality was significantly higher in patients with sarcopenia than in those without (6-months: 25.0% vs. 2.2%; 1-year: 43.0% vs. 4.8%, respectively; p value <0.001). A predictive model including INR, creatinine, and sarcopenia was developed to estimate liver-related mortality. The model achieved good predictive performances with AUCs of 0.826, 0.788, and 0.712 at 6-month, 1-year, and 2-years, respectively.

Conclusion

Due to its significant impact on survival, the evaluation of sarcopenia may improve the selection of older adults candidate to TIPS. The new predictive model for post-TIPS liver-related mortality deserves external validation.

评估肌肉疏松症有助于预测老年肝硬化患者的 TIPS 后死亡率

背景和目的经颈静脉肝内门体分流术（TIPS）已被证明对老年患者（年龄≥70 岁）可行，但选择标准仍不理想。肌肉疏松症在老年人群中非常普遍，可能与 TIPS 术后结果有很大关系。本研究旨在评估基线肌肉疏松症对老年肝硬化患者TIPS术后存活率的影响。方法对意大利前瞻性TIPS-Registry进行回顾性分析，以确定2015年6月至2023年3月期间接受TIPS治疗的年龄≥70岁的患者。基线腹部 CT 扫描是强制性纳入标准。骨骼肌指数（SMI）在 L3-L4 水平进行评估。男性的骨骼肌指数为 50 cm2/m2，女性为 39 cm2/m2。与肝脏相关的死亡概率通过竞争风险分析进行评估。结果共纳入 115 名患者：中位年龄 74 岁（IQR 3.1），62% 为男性，中位干体重指数 25.7（IQR 4.7），60% 患有肌肉疏松症。主要病因是病毒（40%）、酒精相关性肝硬化（23%）和代谢功能障碍相关性脂肪性肝炎（20%）。难治性腹水（57%）是 TIPS 的主要适应症。在平均 20 个月（IQR 20）的随访期间，40 名（34.8%）患者死于肝脏相关原因，16 名（13.9%）患者死于肝外原因。肌肉疏松症患者的肝脏相关死亡率明显高于非肌肉疏松症患者（6 个月：25.0% 对 2.9%）：6个月：25.0% 对 2.2%；1年：43.0% 对 4.9%）：分别为 43.0% 对 4.8%；P 值为 0.001）。我们建立了一个包括 INR、肌酐和肌肉疏松症的预测模型来估算与肝脏相关的死亡率。该模型具有良好的预测性能，6 个月、1 年和 2 年的 AUC 分别为 0.826、0.788 和 0.712。TIPS 术后肝脏相关死亡率的新预测模型值得外部验证。
