Abstract

BACKGROUND & AIMS: Systemic inflammation is a driver of decompensation in cirrhosis with unclear relevance in the compensated stage. We evaluated inflammation and bacterial translocation markers in compensated cirrhosis and their dynamics in relation to the first decompensation.

METHODS

This study is nested within the PREDESCI trial, which investigated non-selective beta-blockers for preventing decompensation in compensated cirrhosis and clinically significant portal hypertension (CSPH: hepatic venous pressure gradient ≥10 mmHg). Blood biomarkers were measured at baseline and at 1 and 2 years in patients who remained compensated and had available samples (n = 164). Values of patients with CSPH were split at each time point by decompensation development in the next time interval after sampling. We also included 54 patients with cirrhosis and subclinical portal hypertension (PH) and 35 controls. We assessed markers of inflammation (interleukin-6 [IL-6], tumor necrosis factor-alpha, von Willebrand factor [vWF], C-reactive protein), macrophage activation (CD14, CD163), intestinal barrier integrity (fatty acid-binding protein [FABP], haptoglobin), and bacterial translocation (lipopolysaccharide [LPS]).

RESULTS

IL-6, CD163, and vWF were higher (0.01) at baseline in patients with cirrhosis and CSPH compared to those with subclinical PH and controls. IL-6 increased (0.05) at 1 year in patients with CSPH, with a greater rise in those who developed decompensation. CD163 was higher (0.01) in patients who decompensated at baseline and 1 and 2 years. FABP was elevated (0.01) in patients with CSPH compared to subclinical PH and controls at baseline and 1 year, while haptoglobin was lower (0.01). LPS was higher (0.01) in patients with CSPH than in those with subclinical PH and controls and increased at 1 year regardless of decompensation development.

CONCLUSIONS

Inflammation and bacterial products are present in the systemic circulation in patients with compensated cirrhosis and CSPH. Progressive inflammation precedes the first decompensation.

IMPACT AND IMPLICATIONS

Systemic inflammation drives cirrhosis progression during the decompensated stage, but its role in the compensated stage is unclear. We evaluated biomarkers of systemic inflammation, intestinal barrier integrity and bacterial translocation in patients with compensated cirrhosis and their dynamics in relation to the first decompensation. We demonstrate that low-grade inflammation and bacterial products are present in the systemic circulation in compensated cirrhosis, provided clinically significant portal hypertension has developed. We also show that worsening of systemic inflammation precedes the development of first clinical decompensation.

摘要

背景与目的

全身炎症是肝硬化失代偿的驱动因素,在代偿期的相关性尚不清楚。我们评估了代偿期肝硬化患者的炎症和细菌易位标志物及其与首次失代偿相关的动态变化。

方法

本研究嵌套于PREDESCI试验,该试验研究了非选择性β受体阻滞剂预防代偿期肝硬化和临床显著性门静脉高压(CSPH:肝静脉压力梯度≥10 mmHg)患者失代偿的效果。对仍处于代偿期且有可用样本的患者(n = 164)在基线、1年和2年时测量血液生物标志物。CSPH患者的值在每个时间点根据采样后下一个时间间隔内失代偿的发生情况进行划分。我们还纳入了54例肝硬化和亚临床门静脉高压(PH)患者以及35例对照。我们评估了炎症标志物(白细胞介素-6 [IL-6]、肿瘤坏死因子-α、血管性血友病因子[vWF]、C反应蛋白)、巨噬细胞活化(CD14、CD163)、肠道屏障完整性(脂肪酸结合蛋白[FABP]、触珠蛋白)和细菌易位(脂多糖[LPS])。

结果

与亚临床PH患者和对照相比,肝硬化和CSPH患者基线时IL-6、CD163和vWF水平更高(P < 0.01)。CSPH患者1年时IL-6升高(P < 0.05),发生失代偿的患者升高幅度更大。基线、1年和2年时发生失代偿的患者CD163水平更高(P < 0.01)。与亚临床PH患者和对照相比,CSPH患者基线和1年时FABP升高(P < 0.01),而触珠蛋白降低(P < 0.01)。CSPH患者的LPS水平高于亚临床PH患者和对照(P < 0.01),且1年时无论是否发生失代偿均升高。

结论

代偿期肝硬化和CSPH患者的全身循环中存在炎症和细菌产物。首次失代偿之前炎症呈进行性加重。

影响与意义

全身炎症在失代偿期驱动肝硬化进展,但其在代偿期的作用尚不清楚。我们评估了代偿期肝硬化患者的全身炎症、肠道屏障完整性和细菌易位的生物标志物及其与首次失代偿相关的动态变化。我们证明,在已发生临床显著性门静脉高压的代偿期肝硬化患者的全身循环中存在低度炎症和细菌产物。我们还表明,全身炎症的恶化先于首次临床失代偿的发生。
