Role of circulating angiogenin levels in portal hypertension and TIPS.

ABSTRACT:

Background

Pathogenesis of portal hypertension is multifactorial and includes pathologic intrahepatic angiogenesis, whereby TIPS insertion is an effective therapy of portal hypertension associated complications. While angiogenin is a potent contributor to angiogenesis in general, little is known about its impact on TIPS function over time.

Methods

In a total of 118 samples from 47 patients, angiogenin concentrations were measured in portal and inferior caval vein plasma at TIPS insertion (each blood compartment n = 23) or angiographic intervention after TIPS (each blood compartment n = 36) and its relationship with patient outcome was investigated.

Results

Angiogenin levels in the inferior caval vein were significantly higher compared to the portal vein (P = 0.048). Ten to 14 days after TIPS, inferior caval vein angiogenin level correlated inversely with the portal systemic pressure gradient (P<0.001), measured invasively during control angiography. Moreover, patients with TIPS revision during this angiography, showed significantly lower angiogenin level in the inferior caval vein compared to patients without TIPS dysfunction (P = 0.01).

Conclusion

In cirrhosis patients with complications of severe portal hypertension, circulating levels of angiogenin are derived from the injured liver. Moreover, angiogenin levels in the inferior caval vein after TIPS may predict TIPS dysfunction.

Project description:ObjectivesPortal vein tumour thrombus (PVTT)-related symptomatic portal hypertension (SPH) leads to a poor prognosis in hepatocellular carcinoma (HCC) patients. A transjugular intrahepatic portosystemic shunt (TIPS) can effectively relieve SPH but its effect remains unclear in PVTT-related SPH. This study aimed to evaluate the clinical value of the TIPS procedure combined with sequential systemic therapy in advanced HCC patients with PVTT-related SPH.MethodsAfter 1:1 propensity score matching (PSM), this retrospective study analysed 42 patients who underwent TIPS placement plus sequential systemic therapy (group A) and 42 patients who received only symptomatic and supportive treatment (group B). The evaluated outcomes were overall survival (OS) and SPH control rate. Cox proportional hazards regression analysis was used to compare OS in the two groups.ResultsIn group A, the technical success rate of the TIPS procedure was 95.2%, and no severe complications occurred. The rebleeding rates in group A and group B were 5.0% and 73.7%, respectively (p < 0.001), and the ascites control rates were 92.0% and 28.0%, respectively (p < 0.001). The median OS of group A was significantly better than that of group B (9.6 [95% CI: 7.1, 12.0] vs. 4.9 [95% CI: 3.9, 5.8], months, p < 0.001). Multivariable analysis showed that TIPS plus sequential systemic therapy (hazard ratio [HR] = 5.799; 95% CI: 3.177, 10.585; p < 0.001) was an independent prognostic factor related to OS. Additionally, PVTT degree (I+II) (p = 0.008), AFP ≤ 400 ng/ml (p = 0.003), and Child-Pugh class A (p = 0.046) were significant predictors of OS.ConclusionTIPS plus sequential systemic therapy is safe and feasible for treating advanced HCC with tumour thrombus-related SPH.Key points• Portal vein tumour thrombus (PVTT) is common in advanced hepatocellular carcinoma (HCC) and transforms compensated portal hypertension into symptomatic portal hypertension (SPH). • HCC patients with PVTT-related SPH have a very poor prognosis, and there are no effective treatments recommended by the guidelines. • Therefore, a treatment strategy that utilises a transjugular intrahepatic portosystemic shunt (TIPS) to manage SPH combined with sequential systemic therapy in advanced HCC patients is explored in this study for its feasibility and clinical value. This research can fill the gap in current research data to provide clinically meaningful treatment options.

Project description:Background and aimsThe liver plays a key role in the storage, metabolism and homeostasis of fat-soluble vitamins. We investigated the relation of Vitamin(Vit)A/D/E serum levels with severity of liver disease and portal hypertension (PHT).MethodsVitA/D/E serum levels were assessed in 234 patients with advanced chronic liver disease (ACLD, i.e. hepatic venous pressure gradient [HVPG] ≥ 6 mmHg). Patients with hepatocellular carcinoma, pre-/post-hepatic PHT, TIPS or liver transplantation were excluded.ResultsMost patients were male (n = 153; 65%) with a median age of 57.6 (49.7-64.5) years. Thirty-two (14%) patients had HVPG 6-9 mmHg, 66 (28%) 10-15 mmHg, and 136 (58%) ≥ 16 mmHg, respectively. VitD deficiency (25-OH-vitamin-D <50 nmol/L) was found in 133 (57%) with higher prevalence in Child-Turcotte-Pugh (CTP)-C: 85% vs. B: 66% vs. A: 47% (p < 0.001). VitD levels displayed significant but weak correlations with hepatic dysfunction and PHT. VitE levels were normal in 227 (97%) patients and displayed no relevant association with hepatic dysfunction or PHT. Only 63 (27%) patients had normal (>1.05 µmol/L) VitA levels, while 58 (25%) had mild (0.70-1.04 µmol/L), 71 (30%) moderate (0.35-0.69 µmol/L), and 42(18%) severe(<0.35 µmol/L) VitA deficiency. VitA correlated with HVPG (Rho = -0.409), CTP score (Rho = -0.646), and serum bile acid levels (Rho = -0.531; all p < 0.001). The prevalence of decompensated ACLD (dACLD) continuously increased with severity of VitA deficiency (no: 40% vs. mild: 51% vs. moderate: 67% vs. severe: 91% had dACLD; p < 0.001). CTP score (per point; OR 2.46; 95%CI 1.80-3.37; p <0.001), age (per year; OR 0.95; 95%CI 0.92-0.98; p = 0.001) and elevated bile acid levels(>10 µmol/L; OR 3.62; 95%CI 1.61-8.14; p = 0.002) were independently associated with VitA deficiency.ConclusionVitA and VitD but not VitE deficiencies are highly prevalent in ACLD. VitA deficiency strongly correlates with hepatic dysfunction, PHT and bile acid levels and is associated with decompensated ACLD.Trial registration numberNCT03267615.
