About

Chronic liver disease end by liver cirrhosis and increases the risk of cancer development. Chronic liver disease in Egypt is recognized as a serious health problem affecting greater than (20 %) of the population, where the main cause is chronic infection.

Liver transplantation is still the standard treatment for advanced decompensated liver cirrhosis. However, this treatment is quite limited in clinical practice. Therefore there is a concerted effort around the world to develop regenerative and alternative therapies, so, stem cell-based therapies are emerging as new alternatives to liver transplantation for end-stage liver pathologies.

Full description

This study aimed to transplant autologous bone marrow derived mesenchymal stem cells to the patients with liver cirrhosis to assess liver tissue regeneration, efficacy and safety of stem cell therapy and finally to establish an alternative treatment modality to liver transplantation.

Medical treatment of liver cirrhosis (the last stage of the illness) is very difficult that leads to high morbidity and mortality rate. Liver transplantation is still the most effective treatment for the patients with liver cirrhosis, However, serious problems are accompanied with liver transplantation, donor shortage, long waiting list, high cost, risk of rejection, operative complications and complications related to immunosuppressive drugs.

"stem cells" are cells in the human body that are capable to renew themselves and differentiate to a diverse range of specialized cell types and can be differentiated to specialized cells in appropriate medias in the laboratory. In recent years, advances in stem cell biology, have made the prospect of tissue regeneration a potential clinical reality, and several studies have shown the great promise that stem cells hold for therapy. mesenchymal stem cell based therapy has shown as promising tool in cirrhotic conditions as this type of cells have the ability to differentiate to different cell types including hepatocytes A series of studies have been performed to assess the application of bone marrow derived mesenchymal stem cells to promote liver regeneration and to alleviate cirrhosis. Some animal-based studies showed that stem cell transplantation could ameliorate liver fibrosis and improve liver functions followed by several clinical trials on human, in patients with advanced liver diseases, these studies demonstrated that stem cell transplantation could significantly reverse hepatic failure with only limited side effects. However, the effectiveness of this therapy in recent clinical trials is still conflicting and need further evaluation.

40 participants in 2 patient groups

Mesenchymal stem cell transplantation

Experimental group

Description:

This group will include 20 patients with liver cirrhosis, autologous bone marrow derived mesenchymal stem cells will be transplanted to them. Every patient will receive 2 million cells per Kg via portal vein once.

Treatment:

Biological: Mesenchymal stem cell transplantation

Control group

No Intervention group

Description:

This group will include 20 patients with liver cirrhosis as control group matching (stem cell group) in age, sex and child score. They will continue on the conventional therapy they already on and no stem cell transplantation will done for them.
