[EX Q]: Question: Does a common UCP2 polymorphism predispose to stress hyperglycaemia in severe sepsis?
Answer: A common, functional polymorphism in the promoter region of the UCP2 gene is associated with hyperglycaemia and insulin resistance in severe sepsis. This has implications for our understanding of the genetic pathophysiology of sepsis and is of use in the stratification of patients for more intensive management.
