Minimal change disease: a review

Area of Science:

• Nephrology
• Immunology
• Pathology

Background:

• Minimal change disease (MCD) is a leading cause of nephrotic syndrome in children and adults.
• The exact pathogenesis of MCD remains unclear, but T-cell dysregulation is strongly suspected.
• Massive proteinuria in MCD results in significant complications including hypoalbuminemia, edema, and hyperlipidemia.

Purpose of the Study:

• To provide a concise overview of Minimal Change Disease.
• To highlight the diagnostic criteria and therapeutic approaches for MCD.
• To underscore the importance of understanding MCD's pathophysiology for improved patient outcomes.

Main Methods:

• Diagnosis relies on characteristic histopathological findings on renal biopsy, considered the gold standard.
• Clinical presentation and laboratory findings support the diagnosis.
• Review of current literature on MCD pathogenesis and treatment.

Main Results:

• Minimal change disease is characterized by nephrotic syndrome with massive proteinuria.
• Renal biopsy is essential for definitive diagnosis, showing normal glomeruli under light microscopy.
• MCD demonstrates a high response rate to corticosteroid therapy.

Conclusions:

• Minimal change disease is a significant cause of nephrotic syndrome, primarily managed with corticosteroids.
• While often idiopathic, T-cell involvement is implicated in MCD pathogenesis.
• Alternative immunosuppressive agents are available for steroid-resistant or frequently relapsing cases.
