Clinical Trial Summary

A minimally invasive procedure to directly assess portal pressure gradient under endoscopic ultrasound guidance (EUS-PPG) has become available and initial data have proved the technique to be safe. Aims of our proposal are: (i) to assess performance of EUS-PPG as compared to HVPG in evaluating hemodynamic response to non selective betablockers (NSBBs) in a large cohort of patients with CSPH;(ii) identification of markers of hemodynamic response(iii) identification of factors potentially affecting the accuracy of PPG measurement.

Description:

Specific Aim 1 To explore the correlation between endoscopic ultrasound (EUS)-guided portal pressure gradient (PPG) and hepatic venous pressure gradient (HVPG) in evaluation of hemodynamic response to non-selective beta blockers (NSBBs) in patients with advanced chronic liver disease and high risk varices. The investigators will perform EUS-PPG measurement and HVPG measurement at baseline and after NSBBs titration in enrolled patients. Hemodynamic response to medical therapy is defined as either a decrease in HVPG by >20% of the baseline value or an absolute value of HVPG < 12 mmHg after dose titration.

Correlation between PPG/HVPG values and development of portal hypertension-related gastrointestinal bleeding or liver- related events (ascites, spontaneous bacterial peritonitis, and hepatic encephalopathy) will be clinically assessed during follow-up with outpatients visits every 2-3 months.

Specific Aim 2 Identification of other markers of hemodynamic response to non selective beta blockers (NSBBs), with focus on elastography modifications and gut microbiota composition. To identify predictors of hemodynamic response, splenic and hepatic elastography measurement will performed at baseline and after NSBBs titration. In the same way the investigators will evaluate the gut microbiota before and after the start of therapy with NSBBs.

Specific Aim 3 Identification of factors potentially affecting the accuracy of PPG measurement. It is well-known that deep sedation may cause inaccurate HVPG values, while mild sedation with low dose midazolam does not modify the HVPG. In a subgroup of enrolled patients the investigators will perform PPG measurement with deep and mild sedation in order to investigate influence of deep sedation on PPG measurement accuracy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measurement of the portal pressure gradient though endoscopic ultrasound (EUS) and hepatic venous pressure gradient (HVPG) to evaluate the hemodynamic response to non-selective beta blockers (NSBBs)	The investigators will measure portal pressure gradient through EUS-PPG measurement at baseline and after NSBBs titration in enrolled patients.	24 months
Primary	Measurement of the portal pressure gradient though endoscopic ultrasound (EUS) and hepatic venous pressure gradient (HVPG) to evaluate the hemodynamic response to non-selective beta blockers (NSBBs)	The investigators will measure portal pressure gradient through HVPG measurement at baseline and after NSBBs titration in enrolled patients.	24 months
Secondary	Markers of hemodynamic response	Spleen Stiffness Measurement (SSM) will be assessed by transient elastography before starting NSBB and using a FibroScan® (Echosens, Paris, France) after an overnight fasting.	24 months
Secondary	Markers of hemodynamic response	Liver Stiffness Measurement (LSM) will be assessed by transient elastography before starting NSBB and using a FibroScan® (Echosens, Paris, France) after an overnight fasting.	24 months
Secondary	Markers of hemodynamic response	The gut microbiota will be collected before and after the start of therapy with NSBBs. Fecal samples will be collected at home in a commercial sterile, dry screw-top container, and frozen at -80 °C within 24 hours, until further processing. Baseline and post NSBBs treatment blood samples collected from portal vein will be drawn, processed and stored at -80°C within 1 hour, until further processing.	24 months
