[Infectious complications after renal transplantation]

Area of Science:

• Nephrology
• Transplantation Immunology
• Infectious Diseases

Context:

• Infections are a major clinical challenge in renal transplantation, impacting graft and patient survival.
• Post-surgical complications and potent immunosuppressive therapies increase infection risk.
• Common early infections include urinary tract infections caused by bacteria and Candida species.

Purpose:

• To highlight the spectrum of infectious complications following renal transplantation.
• To emphasize the role of immunosuppression in increasing infection susceptibility.
• To underscore the importance of a multidisciplinary approach in managing these infections.

Summary:

• Renal transplant recipients face significant risks from bacterial, fungal, and viral infections, notably Cytomegalovirus (CMV) and BK virus (BKV).
• CMV infection, enhanced by mycophenolate mofetil, can lead to various complications including graft rejection and chronic allograft nephropathy.
• BKV is associated with syndromes like hemorrhagic cystitis and ureteral stenosis in immunocompromised patients.
• Monitoring CMV antigenemia (pp65) enables preemptive therapy for virological activity.

Impact:

• Effective management of infections is crucial for improving graft and patient survival in renal transplantation.
• Early detection and preemptive treatment of viral infections like CMV can mitigate severe complications.
• A collaborative, multidisciplinary approach involving nephrologists, surgeons, infectious disease consultants, and clinical microbiologists is essential for optimal patient care.
