[URINE UNDER CHRONIC DYSFUNCTION OF RENAL ALLO-TRANSPLANT]

Area of Science:

• Nephrology
• Biochemistry
• Immunology

Context:

• Chronic dysfunction of renal allografts is a significant clinical challenge.
• Early and accurate diagnosis is crucial for patient outcomes.
• Existing diagnostic methods may have limitations in detecting subtle dysfunction.

Purpose:

• To investigate the utility of various serum and urine biomarkers for characterizing chronic kidney allograft dysfunction.
• To identify reliable indicators of chronic dysfunction in renal allografts.
• To compare the diagnostic performance of different biomarkers.

Summary:

• The study analyzed serum and urine biomarkers including enzymes and interleukins in patients with renal allografts.
• Elevated levels of certain biomarkers like IL-10, beta-2-microglobulin, and N-acetyl-β-D-glucosaminidase were observed in cases of chronic dysfunction.
• Multivariant logistic regression identified urinary N-acetyl-β-D-glucosaminidase activity as a significant independent predictor.
• Beta-2-microglobulin in serum and urine, and urinary N-acetyl-β-D-glucosaminidase showed high diagnostic accuracy (ROC curves).
• Specific thresholds for serum beta-2-microglobulin and urinary N-acetyl-β-D-glucosaminidase/creatinine ratio are proposed for improved diagnosis.

Impact:

• This research highlights the potential of specific biomarkers for non-invasive diagnosis of chronic kidney allograft dysfunction.
• The findings may lead to improved diagnostic strategies, enabling timely intervention and better graft survival.
• Further validation with morphological analysis is recommended to confirm these promising results.
