ABSTRACT

Hepatic venous pressure gradient (HVPG) is the "gold standard" for the diagnosis of portal hypertension, which could be applied in the evaluation of liver cirrhosis. Combined use of HVPG with model for end-stage liver disease (MELD) scoring system may more accurately match the donors and recipients undergoing liver transplantation for liver cirrhosis, select the appropriate timing of surgery, and provide guidance for bridging treatment for patients on the waiting list for liver transplantation. Besides, HVPG may also predict clinical prognosis of liver transplant recipients, and provide evidence for early detection and intervention of potential complications. Therefore, the value of HVPG in preoperative evaluation and prognosis prediction of liver transplant recipients was reviewed, aiming to provide guidance for clinical diagnosis and treatment of liver transplant recipients before and after surgery.

ABSTRACT

Objective:To investigate the clinical value of transjugular liver biopsy (TJLB) in patients with unexplained liver disease complicated with massive ascites or coagulopathy.Methods:A retrospective analysis was performed from patients underwent TJLB in the First Affiliated Hospital of Zhengzhou University, Zhoukou Central Hospital, Shangqiu First People's Hospital and Jincheng People's Hospital from March 2015 to January 2022 due to unexplained liver disease complicated with massive ascites or coagulopathy. A total of 37 patients were included, including 21 males and 16 females, aged (53.5±11.9) years. According to different puncture points, the patients were divided into two groups: transhepatic right vein TJBL and transhepatic middle vein TJBL. The obtained liver tissue sampling effect, puncture times, complications were analyzed.Results:The success rate of TJLB was 97.3%(36/37). Thirty-six patients were able to obtain more than three segments of liver tissue and obtain histological diagnosis, and the pathological diagnosis rate was 100.0%(36/36). The number of puncture times, the amount of hepatic tissue and the number of portal areas in the right hepatic vein group (21 cases) were (3.7±0.9), (3.7±0.7) and (6.5±0.9) respectively, and those in the middle hepatic vein group (15 cases) were (3.7±0.7), (3.7±0.7) and (6.3±0.8) respectively. There were no significant differences between the two groups (all P>0.05). Conclusion:TJLB is safe and feasible for patients with unexplained liver disease complicated with massive peritoneal effusion and coagulopathy. Good liver tissue specimens can be obtained by TJLB from both right hepatic vein and middle hepatic vein.

ABSTRACT

Objective:To investigate the effect of hepatic venous pressure gradient (HVPG) on the prevention of rebleeding in cirrhotic patients of hepatitis B with gastroesophageal variceal hemorrhage receiving endoscopic therapy, and its influence on prognosis.Methods:Fifty eight patients with esophageal and gastric varices due to cirrhosis of hepatitis B admitted to Minhang Hospital Affiliated to Fudan University (from January 2019 to September 2021, n=18) and Zhongshan Hospital Affiliated to Fudan University (from January to September 2017, n=40) were retrospectively included. All of them underwent HVPG determination and endoscopic treatment. They were divided into HVPG≤18 mmHg group and HVPG>18 mmHg group. The rebleeding and survival status of these patients with endoscopic treatment was compared after a follow-up period of 2 years, and Cox regression was performed to analyze the related factors for rebleeding and survival. Results:A total of 58 individuals were included, which were divided into two groups: HVPG≤18 mmHg group (35) and HVPG>18 mmHg group (23). During the 2-year follow-up after the first endoscopic treatment, 13 patients (22.41%) developed rebleeding, including 4 patients in the HVPG≤18 mmHg group and 9 patients in the HVPG>18 mmHg group. The non-bleeding rate in HVPG≤18 mmHg group was significantly higher than that in HVPG>18 mmHg group (91.3% vs 68.7%, RR=3.54, 95% CI: 1.08-11.60, P=0.026), and the difference was statistically significant. Four patients died, including 1 patient in the HVPG≤18 mmHg group and 3 patients in the HVPG>18 mmHg group. There was no statistically significant difference in 2-year survival between the two groups (96.7% vs 86.5%, RR=4.44, 95% CI: 0.45-43.58, P=0.162). Cox regression multivariate analysis was used to analyze the above data, and the results suggested portal vein thrombosis ( HR=3.826, 95% CI: 1.263-11.585, P=0.018), HVPG>18 mmHg ( HR=4.243, 95% CI: 1.290-13.955, P=0.017) were independent risk factors for rebleeding in 2 years after endoscopic therapy. Conclusions:For patients with high HVPG, it should be fully evaluated and considered to receive other pressure lowering therapy, and treatment conversion should be carried out as soon as possible after endoscopic treatment failure.

ABSTRACT

Objective:In this study, the liver, spleen, and hepatic portal vein in the portal venous phase images of abdominal enhanced computed tomography (CT) are artificially segmented and annotated, and the radiomics features are extracted from them. A model for predicting portal pressure in patients with hepatitis B virus (HBV) related cirrhosis is constructed by combining radiomics features with clinical indicators.Methods:A total of 171 patients who had abdominal enhancement CT examination and trans-jugular hepatic venous pressure gradient (HVPG) measurement at the same time were enrolled from January 2016 to May 2020 in the Zhongshan Hospital Affiliated to Fudan University. The liver, spleen, and hepatic portal vein in the portal venous phase images of the CT were manually labeled by using ITK-SNAP 3.8 software. The radiomics features of these three sites were extracted using Python programming, and an HVPG prediction model was established.Results:A total of 171 patients was included in the study. The average age was (51.1±10.3)years, of which 134(78.4%) were males, and the average HVPG was 16.87±5.695. A total of 2 553 radiomics features were extracted from three sites of the portal venous phase images of abdominal enhanced CT in each patient. The 2 553 features extracted were screened using LASSO, and by combing with clinical features and radiomics features, the predictive model of HVPG was obtained: m_HVPG=31.622+ 0.028 8T×total bile acids-6.31(portal venous wavelet-LHH_glcm_ClusterShade)=0.253(portal venous wavelet-LHL_glszm_LargeAreaLowGrayLevelEmphasis)-20.9(spleen wavelet-LLH_glcm_Correlation)-0.000 127(liver original_shape_SurfaceArea)+ 2.79(liver wavelet-LLH_glcm_ClusterShade). The coefficient of determination R2 was 0.345. Conclusions:The study suggests that radiomics features of the liver, spleen, and portal venous combined with clinical features may be used as a non-invasive method to assess the portal pressure in patients with HBV-related cirrhosis.

ABSTRACT

Objective:To investigate the relationship between hepatic venous pressure gradient (HVPG) and parameters of Doppler ultrasound in patients with pyrroidine alkaloid-related hepatic sinusoidal obstruction syndrome (PA-HSOS).Methods:From February 17, 2017 to April 22, 2020, the clinical data of 68 patients with PA-HSOS who underwent HVPG manometry and Doppler ultrasound examination at Drum Tower Hospital, the Affiliated Medical College of Nanjing University were retrospectively analyzed, which included HVPG, Drum Tower severity scoring (DTSS), time from PA-HSOS related symptoms appeared to diagnosis after taking pyrroidine alkaloid (hereinafter referred to as diagnosis time), and parameters of Doppler ultrasound induding portal vein trunk diameter (PD), peak portal vein velocity (PPV), splenic vein trunk diameter (SD) and peak splenic vein velocity (PSV). Receiver operating characteristic curve (ROC) was used to determine the optimal cut-off value of HVPG for predicting non-response to anticoagulation therapy. Binary logistic regression was used to analyze the independent risk factors for non-response to anticoagulation therapy, and Kaplan-Meier survival curve was used to analyze the prognostic survival rate of patients with different HVPG levels. Unitary linear regression was applied to analyze the correlation of HVPG with PD, PPV, SD and PSV in patients with different HVPG levels, patients with mild, moderate and severe DTSS, and patients with diagnosis time >1 month or ≤ 1 month. Chi-square test was used for statistical analysis.Results:The results of ROC analysis showed that the optimal cut-off value of HVPG for predicting non-response to anticoagulant therapy was 20.165 mmHg(1 mmHg=0.133 kPa). The result of multivariate analysis indicated that high HVPG (HVPG>20.165 mmHg) was an independent risk factor for predicting non-response to anticoagulant therapy ( OR (95% confidence interval)=6.039(1.466 to 24.869), P=0.013). Kaplan-Meier survival curve demonstrated that prognostic survival rate of patients with high HVPG was lower than that of patients with low HVPG (HVPG≤20.165 mmHg) (78.4% vs.96.8%), and the difference was statistically significant( χ2=4.74, P=0.030). The results of unitary linear regression analysis showed that there was a negative correlation between HVPG and PPV in 68 patients with PA-HSOS( r=-0.330, P=0.006); HVPG was positively correlated with PD and SD in patients with high HVPG ( r=0.540 and 0.341, P=0.001 and 0.039); there was a negative correlation between HVPG and PSV in patients with mild DTSS ( r=-0.519, P=0.019), HVPG was negatively correlated with PPV in patients with moderate DTSS ( r=-0.400, P=0.014). In patients with diagnosis time ≤1 month, there was a negative correlation between HVPG and PPV ( r=-0.391, P=0.010). Conclusions:HVPG can assist in judging the response to anticoagulation therapy and the prognosis of patients with PA-HSOS. Parameters of Doppler ultrasound can help to assess the degree of HVPG elevation in patients with PA-HSOS under certain conditions.

ABSTRACT

Portal hypertension (PH) is a commonly seen complication of chronic liver disease and is a direct cause of decompensated cirrhosis. Early diagnosis of PH is essential for the treatment and prognosis of liver cirrhosis. Hepatic venous pressure gradient (HVPG) is the gold standard for the diagnosis of PH, but its invasiveness limits its use. At present, progress has been achieved on the noninvasive diagnostic techniques and of which the serological indicators are simple for use, including inflammatory mediators, vasoactive substances, extracellular matrix (ECM) components and their circulating degrading products. This article reviewed the advances in research on serological assessment of PH.

ABSTRACT

Liver fibrosis and cirrhosis, is a chronic, occult progression that is potentially reversible and complicated. The hepatic venous pressure gradient is a "gold standard" for risk stratification of liver cirrhosis and is superior to pathological examination of liver. This article briefly assesses the invasive and non-invasive measuring methods of the hepatic venous pressure gradient. With the hepatic venous pressure gradient-guided precise treatment for hepatic cirrhosis of portal hypertension, the incidence of clinical endpoints of hepatic portal hypertension can be significantly reduced. Establishing a long-term monitoring and management model similar to "high blood pressure" is a dream for the diagnosis and treatment of future cirrhosis and portal hypertension.

ABSTRACT

Objective To evaluate effects of extremely high hepatic venous pressure gradient (HVPG) on the prognosis of endoscopic therapy in secondary prophylaxis for patients with gastroesophageal varices.Methods This was a single center prospective cohort study.From April 1st,2013 to May 31st,2015,patients with gastroesophageal varices and treated for secondary prophylaxis were enrolled and divided into extremely high HVPG group (HVPG≥20 mmHg,1 mmHg=0.133 kPa) and non-extremely high HVPG group (HVPG< 20 mmHg).After combination of endoscopic ligation and tissue glue treatment,one-year,two-year and threeyear rebleeding rates and survival statuses were compared.Cox regression was performed for further analysis of prognosis factors related with rebleeding and survive.Results Eventually,126 patients were enrolled and divided into extremely high HVPG group (32 cases) and non-extremely high HVPG group (94 cases).The one-year rebleeding rates of extremely high HVPG group and non-extremely high HVPG group were 37.9 ℃ (11/29) and 27.6 % (24/87),respectively,and the difference was not statistically significant (x2 =1.105,P =0.293).The two-year rebleeding rate of extremely high HVPG group was significantly higher than non-extremely high HVPG group 51.7% (15/29) vs 29.9% (26/87),and the difference was statistically significant (x2 =4.539,P=0.033).And so was the three-year rebleeding rate,51.7% (15/29) vs 29.9% (24/87),and the difference was statistically significant (x2 =4.539,P=0.033).The one-year,two-year and three-year survival rates of extremely high HVPG group and non-extremely high HVPG group were 92.6% (25/27) vs 94.0% (78/83),85.2% (23/ 27) vs 94.0 % (78/83),and 85.2% (23/27) vs 94.0% (78/83),and the differences between two groups were not statistically significant (all P>0.05).Single factor analysis showed that portal vein thrombosis was associated with rebleeding (hazard ratio (HR)=1.883,95% confidence interval (CI) 1.015 to 3.492,P=0.045).No prognosis factors associated with survival were found.Conclusions Medium and long term rebleeding rate of the extremely high HVPG group is higher than that of the non-extremely high HVPG group.Extremely high HVPG does not affect the one-year prognosis of endoscopic therapy in secondary prophylaxis for patients with gastroesophageal varices.

ABSTRACT

Portal hypertension is a common complication of chronic liver diseases and is responsible for most of the clinical consequences of cirrhosis.Accurate assessment of portal venous pressure is essential for the designing of treatment strategy and judging of prognosis.Measurement of hepatic venous pressure gradient (HVPG) is the gold standard for evaluating portal venous pressure, however, it is an invasive procedure and is hard to be performed routinely in clinical practice.Therefore, it is urgent to explore a noninvasive method for assessing portal venous pressure.Recent evidence highlights that biochemical parameters, transient elastography, CT, MRI and the conjoint analysis model of multiple parameters have the potential diagnostic value.This article reviewed the advances in study on noninvasive assessment of portal venous pressure.

ABSTRACT

Objective To investigate the correlation between liver and spleen stiffness measured by acoustic radiation force impulse (ARFI) and hepatic venous pressure gradient (HVPG),and to evaluate its efficiency in the diagnosis of portal hypertension.Methods From April 2014 to March 2016,20 cases underwent HVPG measurement because of liver cirrhosis were enrolled.Before HVPG measurement,liver and spleen stiffness were assessed with ARFI.The correlation between HVPG and age,alanine aminotransferase (ALT),aspartate aminotransferase (AST),total hilirubin,serum albumin,platelet count,prothrombin time,aspartate aminotransferase to platelet ratio index (APRI) score,Child-Pugh score,model for end-stage liver disease (MELD) score,liver stiffness and spleen stiffness were analyzed.Pearson correlation and Spearman rank correlation were performed for statistical analysis.Results HVPG,liver and spleen stiffness were successfully measured in all 20 patients.The mean liver stiffness was (1.78±0.29) m/s,the mean spleen stiffness was (3.37±0.44) m/s and HVPG was (16.10±5.14) mmHg (1 mmHg=0.133 kPa).Age,ALT,AST,total bilirubin,serum albumin,platelet count,prothrombin time,APRI score,Child-Pugh score and MELD score were all not correlated with HVPG (all P>0.05).But HVPG was positively correlated with liver and spleen stiffness (r=0.449,P=0.047;r=0.487,P=0.030).In the diagnosis of HVPG≥12 mmHg,the area under curve (AUC) of liver stiffness was 0.875,the optimal cut-off value was 1.77 m/s,the sensitivity was 68.6 % and the specificity was 100.0%.In the diagnosis of HPVG≥20 mmHg,the AUC of liver stiffness was 0.798,the optimal cut off value was 1.85 m/s,the sensitivity was 100.0% and the specificity was 68.8%.The AUC of spleen stiffness was 0.820,the optimal cut-off value was 3.23 m/s,the sensitivity was 100.0 % and the specificity was 56.3%.Conclusion In patients with liver cirrhosis,liver stiffness and spleen stiffness assessed by ARFI are positively correlated with HVPG and therefore ARFI has certain application value in the noninvasive diagnosis of portal hypertension.

ABSTRACT

BACKGROUND/AIMS: Non-selective beta blockers (NSBBs) are currently the only accepted regimen for preventing portal hypertension (PHT)-related complications. However, the effect of NSBBs is insufficient in many cases. Bacterial translocation (BT) is one of the aggravating factors of PHT in cirrhosis; therefore, selective intestinal decontamination by rifaximin is a possible therapeutic option for improving PHT. We investigated whether the addition of rifaximin to propranolol therapy can improve hepatic venous pressure gradient (HVPG) response. METHODS: Sixty-four cirrhosis patients were randomly assigned to propranolol monotherapy (n=48) versus rifaximin and propranolol combination therapy (n=16). Baseline and post-treatment HVPG values, BT-related markers (lipopolysaccharide [LPS], LPS-binding protein [LBP], interleukin-6 [IL-6], and tumor necrosis factor α [TNF-α]), serological data, and adverse event data were collected. HVPG response rate was the primary endpoint. RESULTS: Combination therapy was associated with better HVPG response rates than monotherapy (56.2% vs 87.5%, p=0.034). In combination therapy, posttreatment BT-related markers were significantly decreased (LPS, p=0.005; LBP, p=0.005; IL-6, p=0.005; TNF-α, p=0.047). CONCLUSIONS: Rifaximin combination therapy showed an additive effect in improving PHT compared to propranolol monotherapy. These pilot data suggest that the addition of rifaximin to NSBBs could be a good therapeutic option for overcoming the limited effectiveness of NSBBs.

ABSTRACT

PURPOSE: The present study aimed to investigate the role of hepatic venous pressure gradient (HVPG) for prediction of long-term mortality in patients with decompensated cirrhosis. MATERIALS AND METHODS: Clinical data from 97 non-critically-ill cirrhotic patients with HVPG measurements were retrospectively and consecutively collected between 2009 and 2012. Patients were classified according to clinical stages and presence of ascites. The prognostic accuracy of HVPG for death, survival curves, and hazard ratios were analyzed. RESULTS: During a median follow-up of 24 (interquartile range, 13-36) months, 22 patients (22.7%) died. The area under the receiver operating characteristics curves of HVPG for predicting 1-year, 2-year, and overall mortality were 0.801, 0.737, and 0.687, respectively (all p17 mm Hg, respectively (p=0.015). In the ascites group, the mortality rates at 1 and 2 years were 3.9% and 17.6% with HVPG 17 mm Hg, respectively (p=0.044). Regarding the risk factors for mortality, both HVPG and model for end-stage liver disease were positively related with long-term mortality in all patients. Particularly, for the patients with ascites, both prothrombin time and HVPG were independent risk factors for predicting poor outcomes. CONCLUSION: HVPG is useful for predicting the long-term mortality in patients with decompensated cirrhosis, especially in the presence of ascites.

ABSTRACT

Background: Literature regarding safe dose of carvedilol is limited and also safe dose across different child classes of chronic liver disease is not very clear. Aim: We aimed primarily to study, the effect of reasonably safe dose (12.5 mg) of carvedilol in acute reduction of portal pressure and compared it with chronic reduction of portal pressure, after proper optimization of dose of carvedilol. Second aim of our study was to define predictors of response for acute and chronic reduction of portal pressure and to assess difference in dose tolerated and response across different child class on chronic basis. Methods: One hundred two consecutive patients of cirrhosis of liver with significant portal hypertension were included and hepatic venous pressure gradient was measured at the base line and after 90 minutes of administration of 12.5 mg carvedilol. After proper dose optimization of carvedilol, hepatic venous pressure gradient was again measured after 3 months to assess the chronic response. Results: The mean age of study population was 58.3±6.6 years. A total of 42.2%, 31.9% and 26.6% patients had child class A, child class B and Child class C cirrhosis, respectively. Mean pre-drug hepatic venous pressure gradient was 16.75±2.12 mmHg which dropped to 13.07±2.32 mmHg after 90 minutes of administration of 12.5 mg of carvedilol. The mean drop of hepatic venous pressure gradient was 4.5±2.2 mmHg and 2.4±1.9 mmHg among responders and non-responders, respectively. Overall, 51% showed acute response while 49% were nonresponders. Low cardiac output and high mean arterial pressure were significantly predicting the acute response, while, low baseline cardiac output was found as an independent predictor. After dose optimization, number of responders increased from 52 to 62. Mean dose of carvedilol was higher in non–responders as compared to responders, though statistically insignificant (p>0.05). Mean reduction of hepatic venous pressure gradient from baseline and after 3 months was 5.5±1.7 mmHg and 2.8±1.6 mmHg among responders and non responders on chronic basis, respectively (p<0.001). Absence of any adverse events (OR 11.3, 95% CI; 1.9-67.8), and more than 2.5 mmHg fall in hepatic venous pressure gradient during acute response (OR 8.7, 95% CI; 3.1-25.3) were found as independent predictors of chronic response (p<0.05). Univariate analysis found that no adverse events, no ascites, low baseline cardiac output, more than 2.5 mmHg fall in hepatic venous pressure gradient during acute response, as predictors of chronic response. However, etiology, child class, variceal size (large vs small) and gender were not significantly associated with chronic response Conclusion: At safe dose and with proper optimization of dose, carvedilol may achieve greater response with minimum side effects among different child classes of liver disease.
