[Infections after kidney transplantation]

Area of Science:

• Nephrology
• Transplant Surgery
• Infectious Diseases

Background:

• Immunosuppressed kidney transplant recipients are highly susceptible to infectious complications.
• Infections are the primary cause of morbidity within the first six months post-transplant.
• Clinical presentation of infections in immunocompromised patients is often atypical.

Purpose of the Study:

• To highlight the significant infectious risks in kidney transplant recipients.
• To discuss infections affecting the kidney graft in the later post-transplant period.
• To focus on polyomavirus nephropathy as a critical viral disease in renal allografts.

Main Methods:

• Review of infectious complications in immunosuppressed kidney transplant recipients.
• Analysis of infection patterns in early and late post-transplant phases.
• Discussion of specific viral diseases affecting renal allografts, particularly polyomavirus nephropathy.

Main Results:

• Over half of recipients experience infectious complications in the early post-transplant period.
• Infections remain the most frequent cause of morbidity in the first six months.
• Polyomavirus nephropathy identified as the most important and frequent viral disease of renal allografts.

Conclusions:

• Infections pose a substantial threat to kidney transplant recipients, necessitating vigilant monitoring.
• Atypical presentations of infections in this population require careful clinical consideration.
• Polyomavirus nephropathy is a key viral complication impacting long-term graft survival.
