Summary

A randomized controlled trial to study the efficacy of addition of FMT & plasma exchange to tenofovir compared to monotherapy with tenofovir in patients with HBV reactivation who develops Acute on chronic liver failure.

In this study the patients who meet the inclusion criteria will be randomized to either receive Tenofovir or with FMT + plasma exchange along with Tenofovir . Blood samples & stool samples will be taken & analysis will be done accordingly .The patients are followed for 90 days MELD,APACHE & SOFA scores are calculated.Then statistical analysis will be done to find whether the addition of plasma exchange & FMT adds benefit compared to tenofovir treatment alone .

Description

A randomized controlled trial to study the efficacy of addition of FMT & plasma exchange to tenofovir compared to monotherapy with tenofovir in patients with HBV reactivation who develops Acute on chronic liver failure.

In this study the patients who meet the inclusion criteria will be randomized to either receive Tenofovir or with FMT + plasma exchange along with Tenofovir . Blood samples & stool samples will be taken & analysis will be done accordingly .The patients are followed for 90 days MELD,APACHE & SOFA scores are calculated.Then statistical analysis will be done to find whether the addition of plasma exchange & FMT adds benefit compared to tenofovir treatment alone .

Study period: 2 Years

Intervention

The patients in Group A will receive T.Tenofovir [antiviral] 300mg per oral once a day .

The patients in Group B will receive Plasma exchange 2 sessions alternate day followed by FMT for 7 days and Tenofovir [antiviral] 300mg PO once a day .

Intravenous antibiotics will be given to all patients included in study empirically, because of high risk of infection in these patients. Patients with sepsis are excluded from the study.

Methodology for FMT - Fresh Stool [30 g] is obtained from donor <3 hr before FMT. 150 mL sterile 0.9N saline is added to sample & homogenized in a blender. It is Continued 3 times in pulses of 20-30 secs, till homogenous suspension. Slow filtration is done with membrane filter (330µm) to give adequate time. Filtration is repeated 3 times. Patient is kept NPO for 4 hrs. prior to the instillation .100 ml of fresh filtrate is given for 7 days through naso-jejunal tube over 5-10 minutes .Patient is kept reclined at 45° for 4 hr. Normal diet is given after 2 hr of procedure. IV antibiotics are continued as per institutional protocol in case of sepsis.

Methodology for plasma exchange [PE] - Circulatory access will be established through a double lumen catheter via the patient's femoral vein. The total exchanged plasma volume will be 2500-3500 mL, and the Plasma Exchange rate will be 20-25 mL/min. Fresh-frozen plasma (FFP) will be supplied by the ILBS Blood Bank. Dexamethasone (5 mg) and heparin (2500 U) will be injected routinely before PE. Heparin will be neutralized at the end of PE by an injection of 20-50 mg protamine sulfate. PE will be repeated alternate day for a total of 2 sessions Adverse effects: FMT FMT - Sore throat and difficulty in deglutition secondary to naso-gastric tube insertion Plasma exchange PE
