Innovative dialysis technologies such as portable, wearable and implantable artificial kidney systems are being developed with the aim of addressing these issues and improving patient care. An important challenge for these technologies is the need for continuous regeneration of a small volume of dialysate. Dialysate recycling systems based on sorbents have great potential for such regeneration. Novel dialysis membranes composed of polymeric or inorganic materials are being developed to improve the removal of a broad range of uraemic toxins, with low levels of membrane fouling compared with currently available synthetic membranes. To achieve more complete therapy and provide important biological functions, these novel membranes could be combined with bioartificial kidneys, which consist of artificial membranes combined with kidney cells. Implementation of these systems will require robust cell sourcing; cell culture facilit...

On June 12, The Kidney Project was awarded a $1 million Artificial Kidney Prize from KidneyX for advancing its prototype bioartificial kidney toward a full-sized, human scale, with manufacturing and ultimately clinical trials on the horizon. The KidneyX Prize recognizes the advances The Kidney Project has made in showing the feasibility of the bioreactor component of the bioartificial kidney to house kidney cells. “We previously showed the functional proof-of-concept of our device in an animal model,” said Roy, who is a professor of bioengineering at UCSF. “Now we can begin to create full-sized immunoprotective bioreactors that have the clinical capacity to treat patients.” When the kidneys fail during end-stage renal disease (ESRD), the body loses its ability to filter toxins and other molecules from the blood. Patients with ESRD undergo frequent visits to dialysis clinics, unless they are lucky enough to receive a kidney transplant, which itself requires a lifetime on immunosuppressant drugs. The Kidney Project’s device consists of a hemofilter that isolates toxins and other waste from the blood plus a bioreactor, containing live, engineered cells, that balances the composition of filtered blood. It is packaged into a proprietary, biologically neutral shell, precluding immune rejection as well as the need for immunosuppressant drugs, according to Roy. Moreover, its components are modular – the hemofilter could be implanted, on its own, to simplify the dialysis process, e...

• • When your normal, natural kidneys are functioning at their most effici What is an Artificial Kidney and How Does it Work? When you begin to require an artificial kidney and hemodialysis, either one or both of your kidneys have failed, and a medical machine is required to help perform the functions of your kidneys until a more permanent solution can be applied. Patients are diagnosed with kidney failure when a combination of symptoms occurs. These symptoms include vomiting, increased fatigue, nausea and high levels of toxicity in your blood. Testing for kidney failure can be done through blood tests, urine tests and even forms of imaging tests. Your doctor will be able to determine if you should be tested for kidney failure, and when you should be put on a dialysis treatment. Find a premiere kidney doctor who can help you through your dialysis treatment when you contact Dr. Gura's office and schedule a checkup appointment now! To effectively replace the function of your kidney, hemodialysis works to filter your blood out of your body and into an external machine, then returns the filtered blood back into your body. The process of filtering your blood is known as hemodialysis, and the machine through which your blood is filtered is called the artificial kidney. Hemodialysis is usually performed in a hospital when patients are in more desperate need for a complete kidney transplant, but most patients are able to have consistent dialysis treatments performed at a specializ...

Top Questions: 1. What is the status of the bioartificial kidney? The implantable bioartificial kidney is under development, and we have not begun clinical trials. We have shown that the main functional components of the device (the hemofilter and the bioreactor) work together as intended in animals using small-scale prototypes. This gives us confidence that it will work in humans once the device is scaled up with enough capacity. This video summarizes our latest progress: Video of The Kidney Project at UCSF 2. When will clinical trials start? We estimate that the artificial kidney is about 4-5 years away from being ready for clinical trials from a technical perspective. However, we do not yet have all the funding we need (estimated at USD 10 million) to complete the preclinical development, so this timeline could be slower. 3. When will the bioartificial kidney be available for patients? The artificial kidney must undergo multiple rounds of clinical trials before it is approved by the U.S. Food & Drug Administration (FDA) for widespread use. Our goal is to have a device commercially available by the end of the decade (2030), but again this depends on our funding situation, and it is possible that unanticipated technical challenges could slow us down. 4. Will the artificial kidney be available internationally? Or will international patients have to go to the United States for the procedure? Once the artificial kidney is approved by the FDA, we will work with international ...

The Kidney Project’s first artificial kidney is helping with the prevention, diagnosis and treatment of kidney diseases. The artificial kidney is the size of a smartphone. (Good News Network) The Kidney Project’s “The vision for the artificial kidney is to provide patients with complete mobility and better physiological outcomes than dialysis. It promises a much higher quality of life for millions worldwide with kidney failure,” said Shuvo Roy, a faculty member at the University of California San Francisco Schools of Pharmacy and Medicine. Donated RVs help wildfire victims Woody Faircloth and his daughter Luna are delivering donated RVs to families that have lost their homes because of the California wildfires. (Good News Network) The devastating California wildfires have left many people homeless and without resources for months. Woody Faircloth and his daughter Luna, from Denver, Colorado, are donating their time by “Before I got that RV, I felt like I was a burden on everybody that helped me. I slept a lot in tents and in my car. It gave me a place to go,” Wolley said. ‘Chat checkout’ lines combat loneliness The Netherlands is opening “chat checkout” lines to combat loneliness in everyday life among the elderly and others. (Good News Network) Jumbo, a supermarket chain based in the Netherlands, is “Our stores are an important meeting place for many people and we want to play a role in identifying and reducing loneliness. We do this in various ways, including our Kletska...
