Which statement correctly describes lipid nephrosis and minimal change disease?

• A. Lipid nephrosis is an old term for nephrotic syndrome; minimal change disease is most common in children and is typically steroid-responsive with selective albuminuria, while adults more often have FSGS.
• B. Lipid nephrosis is a distinct adult-onset nephrotic syndrome; minimal change disease is rare in children.
• C. Lipid nephrosis occurs only with diabetes; minimal change disease is unrelated to age.
• D. Lipid nephrosis is a form of glomerulonephritis; minimal change disease presents with heavy proteinuria and hypertension.

Answer: (A)

The main idea here is how lipid nephrosis (lipoid nephrosis) relates to minimal change disease and how that presents across ages. Lipid nephrosis is the older term used for nephrotic syndrome that, in children, is most often caused by minimal change disease. Minimal change disease is the most common cause of nephrotic syndrome in kids and is typically steroid-responsive, with selective albuminuria (loss of albumin with relatively preserved other proteins). In adults, nephrotic syndrome more often stems from other diseases, especially focal segmental glomerulosclerosis, and the response to steroids is less predictable.

So this statement is best because it accurately ties the historical term to nephrotic syndrome and correctly notes the pediatric predominance and steroid responsiveness with selective albuminuria, while also acknowledging that adults more commonly have FSGS. The other choices misstate the age distribution, misclassify lipid nephrosis as a distinct adult-onset entity, or describe features (diabetes association, hypertension, glomerulonephritis) that don’t fit minimal change disease.
