by The Need for an Alternative Treatment Option
Kidney disease is a growing global health problem affecting millions of people worldwide. Currently, those with end stage renal disease require either lifelong dialysis or a kidney transplant in order to survive. However, both options have significant limitations. Dialysis is a time-consuming process that must be done multiple times per week and greatly impacts a patient’s quality of life. Transplants also have limitations as there is a severe shortage of donor organs and patients must take immunosuppressive drugs for life which leave them vulnerable to other health issues. Scientists have long been researching alternative treatments that could potentially resolve many of these issues.
The Development of a Global Wearable Artificial Kidney
Researchers from various institutions around the world have been working on developing a small, Global Wearable Artificial Kidney that could provide dialysis-like blood filtration continuously and independently of a traditional dialysis machine. This would allow patients significantly more freedom and flexibility than dialysis provides. The artificial kidney would be implanted via a minor surgical procedure and work continuously 24/7 to filter wastes and excess fluids from the blood just like real kidneys do. Rather than relying on bulky external dialysis machines and frequent visits to clinics, patients could go about their daily lives with the artificial kidney filtering their blood from within their bodies.
One of the pioneering research teams leading this work is the Wearable Artificial Kidney Consortium based at the University of California, San Francisco. Their artificial kidney prototype is about the size of a lunch box and contains a tiny blood filter and dialysate cartridge that works continuously to cleanse the blood. It is surgically implanted in the abdominal cavity and connected to blood vessels. The dialysate cartridge is easily replaced through the skin when spent without need for surgery. Early animal testing has proven successful at keeping lab animals alive and healthy.
Global Wearable Artificial Kidney Challenges of Developing the Technology
While the promise of a Global Wearable Artificial Kidney is exciting, actually developing the technology poses major scientific and engineering challenges. Creating an implant small enough to fit inside the body while also containing all the complex filtration components of dialysis is an immense task. Researchers must ensure the artificial kidney components are made from biocompatible materials and do not trigger negative immune responses. The risk of infections must also be extremely low. Developing new membrane filter materials that can last years without clogging or degrading inside the body is another hurdle. Additionally, components like pumps and sensors must function continuously for extended periods with minimal energy needs.
However, progress is being made on each of these fronts. Collaboration between biomedical engineers, materials scientists and physicians is advancing miniaturization and biocompatibility. New membrane materials with improved properties are in testing. Ultra-low power electronics and energy sources are also areas of focus. Meanwhile clinical researchers are working to establish appropriate pre-clinical testing protocols to evaluate safety and effectiveness prior to human trials. If all goes well, early prototypes may enter first-in-human safety studies within the next 5 years according to estimates from researchers.
Potential Global Impact
If a fully functioning wearable artificial kidney can be developed, the impact on patients with kidney failure worldwide would be immense. It could eliminate the need for dialysis altogether and provide a more normal quality of life. No longer tethered to a machine for hours multiple times a week, people would gain much greater independence, mobility, and ability to work and travel. Kidney transplant waiting lists may also shorten as fewer donor organs would be needed.
From a healthcare system perspective, dialysis consumes vast resources around the globe that a wearable device could help redirect. In many countries, the expense of lifelong dialysis severely strains healthcare budgets. An implanted artificial kidney solution could potentially lower long-term costs of treatment. This in turn may help expand access to therapy in underserved regions where financial constraints currently limit dialysis availability. The ability to treat kidney failure without needing massive infrastructure for dialysis clinics could have an equalizing effect on global healthcare.
Global wearable artificial kidney regulatory approval would also create commercial opportunities. Large medical companies are keeping a close eye on this field and some have expressed interest in partnering with academic research teams for product development and clinical testing. If regulatory clearance occurs, a viable market worldwide for thousands of implantable devices each year could emerge. Overall, a wearable artificial kidney has the potential to transform the lives of kidney disease patients and positively impact global health on a broad scale. Considerable scientific challenges remain but researchers are making promising strides towards this goal.
