Implication of serum copper level, serum zinc level, and copper to zinc ratio in neonatal sepsis.

Background: Zinc and copper are trace elements that have important roles in the function of the immune system. We aimed to compare serum zinc and copper levels in neonates with and without neonatal sepsis.

Methods: This case-control study examined 54 newborns with sepsis and 54 matched healthy controls admitted to the neonatal intensive care unit of Children's Hospital, Bandar Abbas, Iran.
