Acute oxalate nephropathy associated with C lostridium difficile infection

Area of Science:

• Nephrology
• Gastroenterology
• Infectious Diseases

Background:

• Acute oxalate nephropathy is a rare kidney disease.
• It is often linked to chronic diarrheal conditions.
• Only one previous case linked it to acute diarrhea from Clostridium difficile colitis.

Observation:

• A 75-year-old male with existing hypertension, diabetes, and chronic kidney disease presented with acute kidney injury.
• He had recently suffered from Clostridium difficile colitis.
• Kidney biopsy revealed extensive oxalate crystal deposits in the tubules.

Findings:

• The patient's acute kidney injury was attributed to acute oxalate nephropathy.
• Widespread tubular oxalate deposition confirmed hyperoxaluria as the cause.
• Clostridium difficile colitis was identified as the precipitating factor.

Implications:

• This report is the second documented case of acute oxalate nephropathy secondary to C. difficile colitis.
• It underscores the importance of considering acute oxalate nephropathy in patients with acute diarrheal illnesses and kidney injury.
• Early recognition and management are crucial for preventing severe kidney damage.
