Autologous peripheral blood CD34+ stem cells transplanted into 100 patients with advanced cirrhosis / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate whether transplantation of autologous peripheral blood CD34+ stem cells is a viable approach for treating patients with advanced cirrhosis,which is currently hindered by a shortage in liver donors.</p><p><b>METHODS</b>A total of 100 patients with advanced cirrhosis and who had failed to respond to conservative therapy were recruited for transplantation of autologous peripheral blood CD34+ stem cells.The success of transplantation was investigated 6-and 12-months later by measuring markers of liver biosynthesis function (coagulation,albumin level,indocyanine green clearance,Child-Pugh score) and assessing pathological changes (Knodell score) and morphologic changes in the liver tissue.Complications were also recorded during follow-up.</p><p><b>RESULTS</b>The 1-year cumulative survival rate was 100%. Fifty-two patients with massive ascites showed gradual reduction and disappearance of the ascites.Four patients experienced upper gastrointestinal bleeding and three patients developed with hepatic encephalopathy (I-II degree) at 3 months post-transplantation.All patients showed significantly improved liver biosynthesis function,liver elasticity and Knodell score after transplantation (P less than 0.05).</p><p><b>CONCLUSION</b>Autologous peripheral blood CD34+ stem cell transplantation is a safe and effective treatment for advanced cirrhosis,and has high cost-benefit since it improves liver function,liver histology,and quality of life.</p>
