Brief Summary

Recently, mesenchymal stem cell (MSC) transplantation has emerged as a promising treatment for liver cirrhosis in adults. Additionally, bone marrow-derived stem cell transplantation has shown success in treating children with biliary atresia (BA). This study aims to evaluate the efficacy of Umbilical Cord-Derived Mesenchymal Stem Cell (UC-MSC) therapy in BA through a multicentric randomized controlled trial.

Detailed Description

Biliary atresia (BA) is the most common cause of chronic cholestasis in neonates and accounts for at least 50% of pediatric liver transplants. The incidence of BA is estimated to range from 1:5000 to 1:19000 live births. If the operation is not performed, all patients will die due to complications of liver cirrhosis. Recently, mesenchymal stem cell (MSC) transplantation has been found to be a promising treatment for liver cirrhosis in adults. Stem cell transplantation derived from bone marrow has also been successfully applied to children with BA. The aim of this study is to demonstrate the efficacy of Umbilical Cord-Derived Mesenchymal Stem Cell (UC-MSC) therapy in BA by planning a multicentric randomized controlled trial.

GroupInterventionDescription
ControlControlIn this group, UC-MSC will not be administered. This group serves as a passive control. The standard treatments that are routinely provided to Biliary Atresia patients will continue to be administered.
Stem Cell Application GroupStem CellIn this group, UC-MSC transplantation will be administered twice to each patient in the study group via the hepatic artery: the first transplantation will be performed post-surgery at the beginning, and the second one will be performed 6 months later, with a dose of 1 million UC-MSC/kg. The applications will be applied after kasai portoenterostomy.
Primary Outcome Measures
NameTimeMethod
Adverse events2 years

Adverse events will be assessed during the stem cell applications, as well as at 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after the application.

Secondary Outcome Measures
NameTimeMethod
Pediatric End-Stage Liver Disease (PELD) score2 years

Using PELD score (according to the suggestion of The Liver and Intestinal Organ Transplantation Committee in 2009). PELD is calculated based on three indicators: albumin (g / dL), bilirubin (units: mg / dL) and INR (international normalized ratio). Formula: PELD = 10 \* (0.48 \* ln(Serum Bilirubin) + 1.857 \* ln(INR) - 0.687 \* ln(Albumin) + (0.436 if patient is less than 1 year old) + (0.667 if patient has growth failure)). Evaluate the result:

If PELD \<10: good results If 10 \<PELD \<15: average results If PELD\> 15: bad results Albumin (Unit: g / dL), bilirubin (units: mg / dL) and INR (international normalized ratio).

ALT levels (Alanine transaminase)2 years

The levels of ALT will be closely monitored in both groups. The values for this parameter will be recorded and evaluated individually for each patient.

AST levels (Aspartate trasnaminase)2 years

The levels of AST will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

Direct bilirubin levels2 years

The levels of direct bilirubin will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

Total bilirubin levels2 years

The levels of total bilirubin will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

GGT levels (Gama glutamil transferase)2 years

The levels of GGT will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

Liver biopsy2 years

Liver biopsy is a crucial clinical tool for assessing the progression and severity of cirrhosis

Level of cirrhosis2 years

Level of cirrhosis will be assesed with PELD score. Using PELD score (according to the suggestion of The Liver and Intestinal Organ Transplantation Committee in 2009). PELD is calculated based on three indicators: albumin (g / dL), bilirubin (units: mg / dL) and INR (international normalized ratio). Formula: PELD = 10 \* (0.48 \* ln(Serum Bilirubin) + 1.857 \* ln(INR) - 0.687 \* ln(Albumin) + (0.436 if patient is less than 1 year old) + (0.667 if patient has growth failure)). Evaluate the result:

If PELD \<10: good results If 10 \<PELD \<15: average results If PELD\> 15: bad results Albumin (Unit: g / dL), bilirubin (units: mg / dL) and INR (international normalized ratio).

Re-operation rate2 years

The patients who need further surgical intervention will be noted.

Liver transplantation2 years

Liver transplantation will be evaluated. The number of patients requiring a liver transplant, along with the timing of the need, will be recorded.

Albumin levels2 years

The levels of albumin will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

INR (international normalized ratio)2 years

The levels of INR (international normalized ratio) will be closely monitored in both groups. The values for each parameter will be recorded and evaluated individually for each patient.

Cholangitis2 years

The number of cholangitis for each cases will be closely monitored in both groups. The frequency of cholangitis experienced by each patient will be recorded and evaluated.
