Which electrophoresis pattern is associated with juvenile cirrhosis?

• A. Alpha-1 flat curve
• B. Gamma curve
• C. Monoclonal curve
• D. Beta curve

Answer: (A)

In serum protein electrophoresis, the liver manufactures many of the alpha-1 globulins. When juvenile cirrhosis impairs hepatic function, production of these alpha-1 proteins decreases, causing the alpha-1 region to appear diminished or flat on the electrophoretic pattern. This flattening of the alpha-1 band is a characteristic sign of reduced alpha-1 globulins due to liver dysfunction in cirrhosis. While a gamma curve (increased gamma globulins) can occur in chronic liver disease, the specific hallmark for this condition described here is the flat alpha-1 region. Monoclonal patterns point to a plasma cell disorder, and beta-pattern changes are not the typical signature of juvenile cirrhosis.
