A Trial for Comparing Rifaximin, Probiotic and L-ornithine- L Aspartate With Lactulose in Overt Hepatic Encephalopathy.

The goal of this trial is to learn if drugs in group A, B, C and D works to treat reversal of grades in people with overt hepatic encephalopathy. It will also provide information regarding safety of drugs in group A, B, C and D. The main question it aim to answer is:

Which study group is better in treating people of overt hepatic encephalopathy. Researchers will compare experimental group B (rifaximin + lactulose), group C (probiotics + lactulose) and group D (LOLA (L-Ornithine L-Aspartate) + lactulose) to control group A lactulose alone in the reversal of grades for people of hepatic encephalopathy.

Participants will:

Take drug from time of participation in the trial till the end of treatment (day 5) and grade reversal will be observed.

About this study

This clinical trial aim to compare the efficacy of four groups which are group A (lactulose) as controlled group, group B (rifaximin + lactulose), group C (probiotics + lactulose)and group D (LOLA (L-Ornithine L-Aspartate) + lactulose) for treating overt hepatic encephalopathy.

Primary objective: The primary objective of our trial will be to compare the grade reversal in overt hepatic encephalopathy patients from the time of trial participation till the end of trial treatment (day 5) according to West Heaven Criteria in both control and interventional groups.

Secondary objectives:

  • To find the length of hospital stay and recovery time (in days) from hepatic encephalopathy in both control and interventional groups.
  • Monitoring of Adverse drug reactions in both control and interventional groups.
  • To assess the mortality in both control and interventional groups.

This trial is single-centered, parallel, multi-arm, 1:1:1:1 randomized, unblinded, lactulose controlled superiority clinical trial comparing the efficacy of four groups which are group A (lactulose) as controlled group, group B (rifaximin + lactulose), group C (probiotics + lactulose) and group D (LOLA (L-Ornithine L-Aspartate) + lactulose) for the treatment of overt hepatic encephalopathy.

Framework/hypothesis: The experimental group B (rifaximin + lactulose), group C (probiotics + lactulose) and group D (LOLA (L-Ornithine L-Aspartate) + lactulose) are superior to control group A lactulose alone in the reversal of grades for patients of hepatic encephalopathy.

Primary outcomes

  1. Number of participants of overt hepatic encephalopathy are treated by observing reversal in grades by using West Haven Criteria.

    Time frame: From the time of enrollment till the end of treatment (day 5) in the trial.

    To compare the efficacy of group B (rifaximin + lactulose), group C (probiotics + lactulose) and group D (LOLA (L-Ornithine L-Aspartate) + lactulose) with group A (lactulose) as controlled group for the treatment of overt hepatic encephalopathy, grade reversal is examined from the time of participation in the trial till the end of treatment (day 5) according to West Heaven Criteria.

    The West Haven criteria are a widely used system for classifying the severity of hepatic encephalopathy. It grades the condition from Grade 0 (minimal or no symptoms) to Grade 4 (coma) based on the patient's level of consciousness, intellectual function, and behavior.

Secondary outcomes

  1. Time of recovery from encephalopathy (Days)

    Time frame: Time of participation in the study assessed up to 5 days.

    Time of recovery from encephalopathy is defined as the time taken (in days) to recover from grade 2 or above mental state grade to grade 1 or below.

  2. Liver disease severity

    Time frame: time of participation in the trial till the end of treatment (day 5)

    Severity of liver disease will be evaluated by Child-pug class. The Child-Pugh score is a clinical tool designed to evaluate the severity of chronic liver disease, including conditions like hepatic encephalopathy (HE). It classifies patients into three categories: A, B, and C, reflecting the degree of liver dysfunction. A higher score corresponds to more severe liver disease and a worse prognosis. This scoring system aids in assessing liver damage, predicting patient survival, and informing treatment options, such as the necessity for liver transplantation.

    Interpretation:

    Child-Pugh Class A: 5-6 points, indicating well-compensated liver disease. Child-Pugh Class B: 7-9 points, indicating moderately impaired liver function. Child-Pugh Class C: 10-15 points, indicating severely compromised liver function and decompensation.

  3. length of hospital days

    Time frame: time of participation in the study till the patient is discharged or died or till 28 days whichever occur earlier.

    To find length of in- hospital stay (days) is defined as the time patient spent in hospital setting until he/she is discharged.
