Summary
Biolasol solution effectively preserves kidney grafts, minimizing damage and maintaining structural integrity. This novel extracellular perfusion solution shows comparable results to the established ViaSpan, offering a promising alternative for hypothermic kidney preservation.
Area of Science:
- Nephrology
- Transplantation immunology
- Biochemistry
Background:
- Biolasol solution is a novel extracellular perfusion fluid for ex vivo hypothermic kidney preservation.
- It is designed to maintain homeostasis, reduce edema, and preserve graft integrity.
- Biolasol aims to minimize ischemia-reperfusion injury.
Purpose of the Study:
- To evaluate the effectiveness of Biolasol solution in kidney preservation.
- To compare Biolasol with the established ViaSpan solution in a preclinical model.
- To assess the impact of Biolasol on renal structural and functional integrity.
Main Methods:
- Auto-transplantation of kidneys in pigs using Biolasol or ViaSpan preservation solutions.
- Analysis of perfusates, serum, and urine parameters.
- Histopathological examination of renal medulla and cortex.
- Assessment of mean survival time as a measure of efficacy.
Main Results:
- Biolasol significantly reduced levels of marker enzymes (ALT, AST, LDH) and ions (Na, K) in pigs.
- Histopathology confirmed no damage to the renal cortex structure with Biolasol use.
- No significant difference in efficacy was observed compared to ViaSpan.
Conclusions:
- Biolasol solution effectively protects kidneys against ischemia-reperfusion damage.
- Its performance is comparable to the current "golden standard" ViaSpan solution.
- Biolasol represents a viable alternative for hypothermic kidney preservation.

786
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
