Emphysematous pyelonephritis in a transplant kidney

Area of Science:

• Nephrology
• Infectious Diseases
• Transplantation Immunology

Background:

• Emphysematous pyelonephritis (EPN) is a rare, severe necrotizing renal infection characterized by gas formation in the kidney and perinephric tissues.
• EPN typically affects diabetic patients, but can also occur in those with ureteral obstruction or compromised immune systems.

Observation:

• This report details a case of EPN in a 23-year-old female renal transplant recipient.
• The patient presented with a severe necrotizing infection despite not having typical risk factors like diabetes or ureteral obstruction.

Findings:

• The presence of EPN in a renal transplant recipient underscores the vulnerability of immunocompromised individuals to severe infections.
• This case expands the known spectrum of risk factors and patient populations affected by emphysematous pyelonephritis.

Implications:

• Early recognition and management of EPN are crucial, especially in immunocompromised populations like transplant recipients.
• This case emphasizes the need for heightened clinical suspicion for EPN in renal transplant patients presenting with signs of severe urinary tract infection.
• Further research may elucidate specific risks and optimal treatment strategies for EPN in the context of immunosuppression.
