Study Details

Study Description

Brief Summary

In Mexico, alcoholic liver disease is the fourth cause of mortality (INEGI). Patients with severe alcoholic hepatitis have a high mortality at 28 days and 6 months, patients receiving standard therapy with prednisone that are non responders (Lille> 0.45) have a survival of 53.3 ± 5.1 % to 28 days. At present, there is not a completely effective treatment for non responders patients, with a high mortality, so it is necessary to look for other therapeutic strategies.

The omega-5 fatty acid (punicic acid) has been considered a powerful antioxidant, it is an agonist of PPAR gamma, has been shown to reduce lipid peroxidation, and restore levels of antioxidant enzymes such as superoxide dismutase (SOD), catalase and glutathione peroxidase. It has also been shown to inhibit the expression of proinflammatory cytokines (such as IL6, IL8, IL23, IL12 and TNFalpha) through PPAR and modulation delta.

The objective of this study is to evaluate the effect of Omega 5 fatty acid on inflammatory markers and antioxidant-oxidant balance markers in patients with severe alcoholic hepatitis treated with prednisone. HYPOTHESIS. Omega 5 fatty acid being a PPARgamma agonist reduces lipid peroxidation and protein damage, restoring reduced glutathione levels, as well as decreasing proinflammatory cytokines, in patients with Severe Alcoholic Hepatitis treated with prednisone and supplementation with fatty acid Omega 5.

Condition or Disease Intervention/Treatment Phase
  • Dietary Supplement: Omega 5 fatty acid supplement
  • Other: PLACEBO
 N/A

Detailed Description

Double-blind clinical trial.

Two groups:

  • GROUP A (standard treatment): Prednisone 40 mg a day + Placebo (manufactured by the same laboratory with the same presentation and physical appearance as the nanoemulsifyied pomegranate seed oil rich in Omega 5 fatty acid)

  • GROUP B (combined treatment): Prednisone 40 mg per day + nanoemulsifiyied pomegranate seed oil rich in Omega 5 fatty acid (2 capsules of 0.64g each / day).

STUDY UNIVERSE: Patients> 18 years old, indistinct gender, with a diagnosis of severe alcoholic hepatitis.

STUDY POPULATION: Patients with clinical and laboratory diagnosis of alcoholic hepatitis Severe Maddrey score ≥32.

SAMPLE SIZE: Double-blind clinical trial, which will include 20 patients for standard treatment and 20 patients for combined treatment, patients who meet the inclusion criteria will be invited to participate. If they agree to participate (after signing the informed consent), the AUDIT C and CAGE questionnaires will be applied, as well as the measurement of anthropometric values and the taking of 3 blood tubes (2 purple and 1 yellow) for the measurement of cytokines, markers of oxidative stress, lipid peroxidation and protein carbonyls.

The initial evaluation will include liver ultrasound, heart rate, blood pressure, temperature, anthropometric evaluation (weight (kilograms), height (meters), BMI (kg/m2), evaluation of ascites (abdominal circumference), hepatic encephalopathy (West Haven Scale). Alcohol abuse will be assessed using the AUDIT and CAGE score. Start-up laboratories will be carried out: TP, INR, Complete liver function tests (BT, BD, FA, AST, ALT, GGT, Albumin), Seric electrolytes (Na, K, Phosphorus, Magnesium), Creatinine, Blood cytometry (Leukocytes (PMN) ), hemoglobin, VCM, platelets), lipid profile (ColT, HDL, LDL, TGs), ferritin and transferrin saturation, Anti-nuclear antibodies, Anti mithochondrial antibodies, AgHBs, AcHBc, anti HCV, anti HIV. The scrutiny of bacterial infections will be carried out through urine culture, blood cultures and in case of suspicion of SBP (paracenthesis). Child-Pugh score (A5-6, B7-9, C10-12), Maddrey score, MELD, ABIC score, Glasgow score. Chest x-Ray, General Urine Test.

Patients who meet the inclusion criteria, previously described, will be proposed to participate in the study, explaining in detail the procedures as well as the studiesthat will be performed. If they agree to participate, they will proceed to the signature of the informed consent by the patient and their responsible family member. Samples (2 yellow tubes and 2 purple tubes) will be taken for the measurement of cytokines, markers of oxidative stress, lipid peroxidation and protein carbonyls prior to the supply of the supplement vs placebo as well as the start of standard treatment. It will be explained to the patient that these samples will be done in 4 times (at diagnosis, on day 7, 14 and 28), which will be carried out during their hospitalization and follow-up.

Both treatments will be taken for 28 days.

Study Design

Study Type:
Interventional
Anticipated Enrollment :
40 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
Randomized, Double-blind clinical trial.Randomized, Double-blind clinical trial.
Masking:
Single (Participant)
Masking Description:
Subjects will be randomly assigned to one of the two treatments. The randomization is done through a computer generated system. The labelling will be done by a pharmacist or similar. Envelopes with randomization listings will be stored in a secure environment within the Hospital. Blinding should be maintained throughout the study. The randomization code should not be broken during the course of the study unless it is necessary for the safety of the subjects, as judged by the investigator. The date, time and reason for unmasking must be recorded, along with the researcher's signature. The rupture of the study blind will be done once the database has been blocked. The study will be double-blind, which means that neither the patients nor the study site staff will have access to the randomization code until the code is broken.

    Outcome Measures

    Primary Outcome Measures

    1. 30 Day Survival [day 30]

      Better survival in patients with omega 5 supplement associated to prednisone

    Secondary Outcome Measures

    1. Rate of reponse to steroids at day 7 [day 7]

      To describe the response to steroids (Lille score) at 7 days of treatment in patients with severe alcoholic hepatitis with combined treatment (Omega 5 and steroids) compared to standard treatment. (Lille response describe a below of 0.45)

    2. Malondialdehyde serum levels [basal, day 7, day 14 and day 28]

      To determine the serum concentrations of lipid peroxidation molecules (malondialdehyde (MDA expressed in mM) in patients with severe alcoholic hepatitis treated with prednisone compare to those treated with prednisona and omega5.

    3. Oxidative Stress molecules serum levels [basal, day 7, day 14 and day 28]

      To assess changes in oxidative stress markers (Oxidative glutation and reduced glutation expressed in mM) in patients with severe alcoholic hepatitis treated with prednisone compared to those treated with prednisone and omega 5.
