How would you describe the pattern of serum proteins in nephrotic syndrome?

• A. Normal levels of all proteins
• B. Decreased albumin with increased alpha-1 globulin
• C. Increased albumin with decreased alpha-2 globulin
• D. Decreased albumin with increased alpha-2 globulin

Answer: (D)

In nephrotic syndrome, the primary abnormality observed in serum protein levels is a significant decrease in albumin due to proteinuria, which is the excessive excretion of protein in urine. This reduction in albumin contributes to a variety of clinical effects, including edema and increased lipid levels.

Simultaneously, there is often an increase in alpha-2 globulins, which consist of proteins such as haptoglobin and alpha-2-macroglobulin. This increase can be a result of the body’s response to the decreased oncotic pressure from low albumin levels, as the liver produces more alpha-2 globulins in an attempt to compensate for the protein loss.

Understanding this pattern is critical, as it reflects the underlying pathophysiology of nephrotic syndrome, correlating with clinical findings such as hypoalbuminemia and edema. The combination of decreased albumin and increased alpha-2 globulins characterizes the serum protein profile in this condition.
