Which finding is most characteristic of nephritic syndrome compared with nephrotic syndrome?

• A. Hematuria
• B. Proteinuria >3.5 g/day
• C. Hypoalbuminemia
• D. Severe edema due to hypoalbuminemia

Answer: (D)

Hematuria is the hallmark feature that distinguishes nephritic from nephrotic syndrome. Nephritic syndrome reflects glomerular inflammation, which disrupts the capillary walls and lets red blood cells leak into the urine, often with red blood cell casts. You’ll also see some protein in the urine, but not in nephrotic quantities, and you may have hypertension and a rising creatinine indicating reduced kidney function. In nephrotic syndrome, the defining problem is heavy loss of protein in the urine (more than 3.5 g/day) leading to hypoalbuminemia, which drives generalized edema. Hyperlipidemia can also be present. So while edema and hypoalbuminemia characterize nephrotic syndrome, they are not the most characteristic features of nephritic syndrome. Thus, among the options, hematuria best captures what is most characteristic of nephritic syndrome in contrast to nephrotic syndrome. The severe edema due to hypoalbuminemia point toward nephrotic syndrome, and very heavy proteinuria also fits nephrotic syndrome rather than nephritic.
