Hyperferritinemia in a kidney transplant recipient.

Area of Science:

• Nephrology
• Hepatology
• Clinical Biochemistry

Background:

• Ferritin is the primary iron storage protein, mainly found in cytoplasm.
• Hyperferritinemia, often linked to iron overload, is common in chronic kidney disease.
• Causes include inflammation, malnutrition, and neoplasia.

Observation:

• A kidney transplant patient presented with severe hyperferritinemia and liver dysfunction one year post-transplant.
• The patient showed no signs of inflammation, malignancy, or chronic viral hepatitis.
• Elevated transferrin saturation and plasma iron supported iron overload.

Findings:

• Identified severe hyperferritinemia in a kidney transplant recipient.
• Ruled out common causes like inflammation, malignancy, and hepatitis.
• Determined iron overload as the probable cause of hyperferritinemia.

Implications:

• Highlights iron overload as a potential cause of hyperferritinemia in transplant patients, even without inflammation.
• Suggests the need for careful iron level monitoring post-kidney transplantation.
• Underscores the importance of considering iron overload in unexplained hyperferritinemia.
