Renal comorbidity after solid organ and stem cell transplantation.

Area of Science:

• Nephrology
• Transplantation Medicine
• Immunology

Background:

• Acute kidney injury is common after solid organ and hematopoietic stem cell transplantation.
• A significant portion of patients develop chronic kidney disease (CKD) and end-stage renal disease.
• CKD incidence and severity vary by transplanted organ and patient-specific factors.

Purpose of the Study:

• To review risk factors for post-transplant CKD.
• To analyze the incidence and mortality rates of acute and chronic kidney disease post-transplant.
• To introduce the RECAST registry for tracking renal comorbidities.

Main Methods:

• Literature review of risk factors for CKD after transplantation.
• Integration of incidence and mortality data for acute and chronic kidney disease.
• Description of the RECAST (REnal Comorbidity After Solid organ and hematopoietic stem cell Transplantation) registry.

Main Results:

• Key risk factors for CKD include pre-existing renal disease, hepatitis C, diabetes, hypertension, older age, male sex, post-transplant acute kidney injury, and thrombotic microangiopathy.
• The incidence of CKD varies significantly based on the type of organ transplanted.
• Associated mortality rates for both acute and chronic kidney disease post-transplant are significant.

Conclusions:

• Post-transplant CKD is a major complication with considerable incidence and mortality.
• Identifying and mitigating risk factors is essential for improving patient outcomes.
• The RECAST registry aims to enhance understanding and management of renal comorbidities in transplant recipients.
