title: Haemolytic disease of the newborn due to maternal irregular antibodies in the Chinese population in Taiwan.
abstract: From 1991 to 2000, amongst 23,886 full-term healthy Chinese babies delivered at our hospital, 2615 babies developed neonatal hyperbilirubinaemia. After excluding other causes of hyperbilirubinaemia and identifying the irregular antibodies, 15 cases of haemolytic disease of the newborn (HDN) due to maternal irregular antibodies were diagnosed; three cases were born in our hospital and 12 cases were referred. Amongst these 15 babies, six cases had HDN due to anti-E, three cases due to anti-E + c, three cases due to anti-D, one case due to anti-c and two cases due to 'Mi' antibodies reacting with MiIII phenotype cells (anti-Hil and anti-Mur). Although there were four cases of hydrops fetalis, only one of the patients expired. The prevalence of HDN caused by maternal irregular antibodies has been estimated to be 0.01%. Therefore, routine prenatal screening for irregular antibodies was not rational in the Chinese population in Taiwan. Anti-E and anti-E + c were the important irregular antibodies resulting in HDN. Although few cases of HDN due to anti-'Mi' have been reported, Anti-'Mi' is significant in regions with a high prevalence of the MiIII phenotype.
