Differential Diagnosis for Elevated Protein Levels and Elevated Uric Acid

Single Most Likely Diagnosis

  • Chronic Kidney Disease (CKD): This condition often presents with elevated protein levels in the urine (proteinuria) due to kidney damage and can also lead to elevated uric acid levels as the kidneys are less efficient at filtering waste products, including uric acid.

Other Likely Diagnoses

  • Nephrotic Syndrome: Characterized by heavy proteinuria, hypoalbuminemia, and edema. The significant loss of protein can lead to various metabolic imbalances, potentially affecting uric acid levels.
  • Diabetic Nephropathy: A complication of diabetes that can cause proteinuria and, over time, lead to kidney failure, which might result in elevated uric acid levels.
  • Gout: While primarily known for causing acute arthritis due to uric acid crystal deposition, chronic gout can lead to kidney damage (gouty nephropathy), potentially causing proteinuria.

Do Not Miss Diagnoses

  • Multiple Myeloma: A plasma cell malignancy that can cause kidney damage leading to proteinuria (often with Bence-Jones proteins) and elevated uric acid levels due to high cell turnover and renal impairment.
  • Lymphoma: Certain types of lymphoma can infiltrate the kidneys, causing damage that leads to proteinuria, and can also result in elevated uric acid levels, especially during tumor lysis syndrome.

Rare Diagnoses

  • Amyloidosis: A condition characterized by the deposition of amyloid proteins in various tissues, including the kidneys, leading to proteinuria and potential kidney failure, which could result in elevated uric acid levels.
  • Tumor Lysis Syndrome: Although more commonly associated with acute kidney injury and hyperuricemia in the context of cancer treatment, it can also present with proteinuria due to kidney damage.
  • Leptomeningeal Metastases: In rare cases, metastatic disease to the leptomeninges can cause kidney dysfunction indirectly, leading to proteinuria and elevated uric acid levels, though this would be an uncommon presentation.
