Immunoglobulins in umbilical cord plasma. 3. Haemolytic disease of newborn and respiratory distress syndrome.

Abstract

The concentrations of IgG [immunoglobulin G], IgA, IgM, and albumin were estimated in the umbilical cord plasma of 42 cases of hemolytic disease of the newborn and 15 infants who developed respiratory distress syndrome. No differences of statistical significance were found from the concentrations present in healthy infants. No difference was found in the concentration of IgG in samples of maternal and umbilical cord plasma from cases of hemolytic disease of the newborn before and after absorption of anti-Rh antibodies.
