The team of Professor Dr Stefan R. Bornstein, Director of the Department of Medicine III in Dresden, implanted the bio-reactor in a patient. The results of the first year are now published in the Journal of Proceedings of the National Academy of Sciences (PNAS 2013; doi:10.1073/pnas.1317561110).
The novel approach has the potential to replace the transplantation with subsequent immunosuppression. However, more research and a broader study is necessary before a large number of type 1 diabetes patients could benefit from this findings.
For the very first time ever, a patient with type 1 diabetes got an artificial pancreas system implanted which produces vital insulin in islet cells like in the pancreas. The small bio-reactor which looks like a little tin has been in the patient body for about one year. The artificial system which has been developed by an Israeli company supersedes an immunosuppression completely. The donor cells will be protected against immune system responses of the patient.
In reverse the insulin will be released into the body. Prof Bornstein, Director of the Department of Medicine III at the University Hospital: “The controlled supply of the cells with oxygen is vital to keep them alive.” He is convinced that the new system shall revolutionise the therapy of diabetes. Many more patients with diabetes type 1 will benefit from a transplantation of islet cells because the recipients do not need any immunosuppressive drugs for their lifetime.
„This is further proof of 20 years successful alliance of medical research and care in Dresden”, says Prof. Michael Albrecht, Medical Manager of the University Hospital Carl Gustav Carus. “This impressive result shows our demand implementing basic research in favour of our patients – the primary objective of the Medical Faculty in Dresden”, says Prof Dr Heinz Reichmann, dean of Medical Faculty Carl Gustav Carus of Technical University Dresden.
Nobel medicine winner Prof Andrew V. Schally of Miller School of Medicine at the University of Miami, who has a research collaboration with Dresden, pronounced “This is a success of historical meaning“. Despite medication, some patients with type 1 diabetes suffer of life threatening deviation of their glucose balance. Transplantation of pancreas as well as islet cells are the only two options to replace insulin producing beta cells and restore the physiological function of insulin production. Both options mean a considerably better control of diabetes and quality of life for the patient. However, the permanent taking of immunosuppressive drugs makes patients susceptible for infections and other adverse effects like a higher risk of cancer. Therefore, these treatments were considered for patients with special medical requirements only.
Dr Barbara Ludwig started the program of transplantation of human beta cells of the islets of Langerhans in 2008. It is the first and only centre of its kind in Germany. The main interest of Dr Ludwig’s group is the quality improvement of human beta cell transplantations. The artificial pancreas system was intensively tested in animals with the colleagues from Israel. The result of this cooperation project was recently published in Proceedings of the National Academy of Sciences (PNAS 2013; doi:10.1073/pnas.1317561110).
Surely, more work has to be done, but Prof Bornstein is certain that the new system will be a serious option in therapy of diabetes in five years time.Contact:
