Study Details

Study Description

Brief Summary

Carvedilol has emerged as the preferred non-selective β-blocker (NSBB) for treating portal hypertension. However, there is still a debate in dosing regimen, specially regarding dose interval, with a potential lower bioavalability in once daily regimens. The aim of this study is to assess the acute effects of carvedilol posology in patients with clinically significant portal hypertension (CSPH), as a surrogate marker of bioavailability.

In this experimental study, patients with CSPH receiving carvedilol twice daily were asked to supress the night dose of carvedilol, in order to have a dose interval of approximately 24 hours. Spleen stiffness measurement (SSM) by transient elastography (TE) was performed and compared with SSM prior or under treatment. Same procedure was applied to liver stiffness measurement (LSM).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Patients with CSPH receiving carvedilol twice daily and supress the night dose of carvedilol

In this experimental study, 34 patients with CSPH receiving carvedilol twice daily were asked to supress the night dose of carvedilol, in order to have a dose interval of approximately 24 hours. Spleen stiffness measurement (SSM) by transient elastography (TE) was performed and compared with SSM prior or under treatment. Same procedure was applied to liver stiffness measurement (LSM).

Outcome Measures

Primary Outcome Measures

  1. spleen stiffness measurement (SSM) [Baseline SSM measured up to 3 months before enrolment, and measured at 24 hours after suspending carvedilol]

    Change from baseline in spleen stiffness measurement (SSM) measured by transient elastography (TE) after 24 hour suspension of carvedilol treatment.

Secondary Outcome Measures

  1. liver stiffness measurement (LSM) [Baseline LSM measured up to 3 months before enrolment, and measured at 24 hours after suspending carvedilol]

    Change from baseline in liver stiffness measurement (LSM) measured by transient elastography (TE) after 24 hour suspension of carvedilol treatment.
