Estrogen Protects After Effects of Kidney Transplantion

Kidney transplantation outcomes are adversely affected by ischemia-reperfusion injury, which occurs as a result of blood flow restrictions.

Ischemia-reperfusion injury is one of the adverse effects which occurs as a result of blood flow restriction during the reperfusion stage of kidney transplant surgery.

In animal models of transplantation, females show increased tolerance to ischemia compared to males, but it is unclear whether sex disparities extend to human kidney transplantations. The research led by Matthew Levine at the University of Pennsylvania linked female resilience to renal ischemia with protective effects of estrogen.

Paired Donor Exchange Kidney Transplantation
Paired donor exchange kidney transplantation is a process in which unrelated kidney donors are matched to recipients so that compatible transplants can be performed.

Female mice displayed increased survival rates and lower levels of kidney injury compared to males following induced renal ischemia. The effects were attenuated in neutered females, but supplemental estrogen prior to the ischemic episode restored protection.

Moreover, an analysis of over 46,000 human kidney transplantation outcomes associated greater failure rates in male compared to female transplant recipients. These findings suggest that improved female outcomes after kidney transplantation may be due to protective effects of estrogen, providing a mechanistic basis for potential therapeutic interventions for renal ischemia.

About Transplantation
Since the early times, the novel idea of transplanting tissues and other body parts from one organism to the other has captured the imagination of successive generations.

Diabetic Kidney Disease - Symptoms, Signs, Causes, Diagnosis, Stages & Treatment
Diabetic nephropathy refers to kidney damage due very high levels of blood sugar levels in diabetics.

Acute Renal (Kidney) Failure- Causes, Symptoms, Diagnosis, Treatment and Complications
Acute renal failure is the sudden cessation of the functioning of kidneys, that can be due to reduced renal blood flow, damage to renal tissues.

Renal ischemia reperfusion injury is the deficiency of blood in one or both kidneys, or nephrons, usually due to functional constriction or actual obstruction of a blood vessel due to lack of oxygen supply.
