Causes and Symptoms of Kidney Failure
Kidney failure can result due to various causes like diabetes, high blood pressure, glomerulonephritis (inflammation of glomeruli), polycystic kidney disease and toxic drugs/chemicals. Common symptoms include fatigue, nausea, loss of appetite, swollen feet/ankles and shortness of breath. Patients may also experience itchy skin, trouble concentrating and urine output changes. As kidneys fail, toxins start to accumulate in the body which can lead to serious health issues if left untreated.
Current Treatment Options - Dialysis and Transplant
Currently, the treatment options for ESRD patients are dialysis and Artificial Kidney transplant. Dialysis is a process of filtering and cleaning blood through a machine that acts as an Artificial Kidney. There are two main types - hemodialysis which uses a machine and catheter to filter blood outside the body 3 times a week, and peritoneal dialysis which uses the inner lining of abdomen (peritoneal membrane) as a filter with exchanges done manually at home daily. Both are life-sustaining but have limitations like inability to remove all waste, risk of infections, dietary/lifestyle restrictions.
Kidney transplant is the best option for suitable patients. In this procedure, a donated kidney from a deceased or living donor is surgically implanted to replace failed kidneys and restore normal function. However, there is lifelong dependency on immune-suppressing drugs to prevent organ rejection. Other challenges include finding a perfect donor match and high costs involved. Even with transplants, nearly 50% fail within 10-15 years requiring return to dialysis.
Limitations of Current Options Drive Development of New Therapies
While dialysis and transplant have saved millions of lives, they have significant limitations which has prompted intensive research to develop better alternatives. Dialysis, though life-saving, is a grueling process and patients are often sickly. Transplants are in shortage and drug side effects take a toll. These challenges have driven scientists and medical device companies globally to explore next-generation therapies like bioartificial and wearable kidney devices.
Artificial Kidney: An Innovative Alternative in Development
Hemodialysis has emerged as a promising alternative in advanced clinical testing stages. It aims to leverage biotechnology and microengineering principles to replicate essential kidney functions like filtration, reabsorption and secretion within an extracorporeal device. Early versions focused on filtration only but latest prototypes can potentially mimic full kidney physiology outside body. For example, a university spinoff is developing a bioHemodialysis platform combining living renal cells and microchip technology. Kidney cells grown on a biodegradable scaffold are perfused across a high-surface area microchip for metabolic exchange, toxin removal and hormonal regulation.
Several Benefits of Hemodialysis over Traditional Options
If proven safe and effective, an Hemodialysis could offer substantial advantages. Firstly, it could provide sustained kidney-like function without the need for organ transplantation or long-term dialysis. This makes it a potential cure for kidney failure. Secondly, it promises better waste clearance compared to dialysis and minimize dietary restrictions. Since toxin removal is via living renal cells instead of a machine, patient well-being may improve significantly. Further, as a permanently implanted device, it can restore near-normal lifestyle and freedom from reliance on dialysis visits. With miniaturization, next-gen designs may even be wearable or even implantable. Overall, an Hemodialysis aims to bridge the gap between dialysis and transplantation.
Clinical Testing and Progress to Date
Several research teams across top institutes like Harvard, MIT and University of California have been developing Hemodialysis prototypes over last decade. Early proof-of-concept models in animal studies successfully filtered blood and removed uremic toxins. In 2019, the first human clinical trial of an Hemodialysis implanted a wearable dialysis device called Kidney project for 48 hours in end-stage kidney disease volunteers in Barcelona, Spain. The device showed 95% toxin clearance compared to standard dialysis without adverse events, demonstrating future potential. Larger human trials are now underway for dialysis and bioHemodialysis devices to evaluate long-term safety, performance and therapeutic impact.
Challenges for Future Development and Adoption
While tremendous progress has been made, bringing an Hemodialysis from concept to reality faces many challenges. Firstly, the device must demonstrate superior and consistent kidney function without causing harm for several years of chronic use. Ensuring biocompatibility of all materials is critical. Recreating full kidney physiology is a formidable task requiring breakthroughs in fields like tissue engineering and drug delivery. Regulatory approvals from agencies like FDA for human implants require extensive multi-year clinical trials. Cost and manufacturing challenges to produce commercial-scale devices need solutions. Finally, public and medical community must embrace a disruptive technology. Overall, it may take considerable efforts to realize an Hemodialysis's ultimate promise. But the impetus is strong giving renewed hope to millions globally affected by kidney disease.
Artificial Kidney has emerged as an enormously impactful frontier in organ replacement therapy. While dialysis and transplantation have saved lives, they have significant drawbacks prompting development of a more definitive solution. The latest generation of bioengineered Hemodialysis are making promising clinical progress, replicating kidney functions outside the body with enhanced biocompatibility. If technology and clinical testing milestones are met, Hemodialysis could potentially revolutionize the management of kidney failure providing a cure instead of chronic therapy. Tremendous discoveries would still be required to reach the goal but initial advances offer new hope to patients.
