The Effectiveness and Safety for Mesenchymal Stem Cell for Alcoholic Liver Cirrhosis
Recruitment status was: Recruiting
Background & Aim: Bone marrow derived mesenchymal stem cells (BM-MSCs) have capacity to differentiate into hepatocytes and anti-fibrotic effect in the experimental model. No study was done in humans with alcoholic liver cirrhosis. The researchers investigated the anti-fibrotic effect of BM-MSCs in alcoholic cirrhosis as Phase II clinical study.
Methods: Eleven alcoholic cirrhosis patients (M:F = 10:1) with Child-Pugh's class B and maintenance of alcohol abstinence at least 2 months were enrolled. At baseline, all patients received liver biopsy, hepatic venous pressure gradient (HVPG) measurement and serologic tests. BM-MSCs were isolated from each patient's BM and amplified for one month and injected two times at 4, 8week through Rt. hepatic artery. 5x106cells/mL of BM-MSCs were injected in each session. Follow up biopsy, HVPG and relative expression of tissue transforming growth factor-1 (TGF-β1), α smooth muscle actin (α-SMA) and collagen-1 by real time RT PCR were measured after 12weeks from 2nd BM-MSC injection. The primary outcome was improvement in patients' histology Aim :
The researchers aimed to evaluate safety and effectiveness of new therapy with bone marrow derived autologous mesenchymal stem cell for hepatic failure caused by alcoholic liver cirrhosis.

|Official Title:||The Evaluation of Effectiveness and Safety for New Therapy With Bone Marrow Derived Autologous Mesenchymal Stem Cell for Hepatic Failure Caused by Alcoholic Liver Cirrhosis|
- The improvement of Liver Histologic grade [ Time Frame: 6 months later ]according to Metavir and Laennec fibrosis scoring system
- The evaluation of hepatic dendritic cells activity by immunohistochemistry [ Time Frame: baseline and 6 months later ]
- Liver fibrosis quantitative analysis using Hydroxyproline contents in liver tissue [ Time Frame: baseline and 6 months later ]Hydroxyproline is a essential component of collange fiber
- Real-Time Polymerase Chain Reaction for relative mRNA expression of TGF-beta, collagen, procollagen, MMP2 or 9 [ Time Frame: baseline and 6 months later ]
- Hepatic venous pressure gradient(HVPG) [ Time Frame: baseline and 6 months later ]HVPG is a gold standard to measure the portal hypertension.
- Hepatic vein arrival time using microbubble contrast enhanced ultrasonography [ Time Frame: baseline and 6 months later ]Hepatic vein arrival time is related with portal hypertension and intrahepatic inflammation, neoangiogenesis and shunts formation secondary to hepatic fibrosis.
- Liver stiffness measurement with transient elastography [ Time Frame: baseline and 6 months later ]Recently, hepatic fibrosis can be estimated non-invasively using transient elastography (Fibroscan, commercial name) and it can be additive data in estimation of therapeutic response.
- Child-Pugh score [ Time Frame: baseline and 6 months later ]
- MELD score [ Time Frame: baseline and 6 months later ]

Experimental: MSC injection
This study is designed as single interventional arm without comparative arm. MSC injection means hepatic artery catheterizations and mesenchymal stem cell injection through catheter.
Biological: mesenchymal stem cell injection
Hepatic artery catheterization and mesenchymal stem cell injection will be used in alcoholic liver cirrhosis. And before and 1 month after injection, change of liver cirrhosis and portal hypertension will be evaluated.
