[Anti-D isoimmunization severe in a twin pregnancy. Case report].
Perinatal hemolytic disease occurs secondary to a hemolytic phenomenon of immune origin resulting in fetal or neonatal anemia. A 38-year-old pregnant woman was referred to the Department of high risk Obstetrics, Hospital Universitario La Paz Madrid because of presenting a dichorionic diamniotic twin pregnancy spontaneously, pre-pregnancy diabetes poorly controlled and severe alloinmunization anti-D. Her first pregnancy ended in a normal delivery at term; in the period of 4 years, she has three newborn with 36, 34 and 40 weeks respectively, who die with a week of life. After that, two intrauterine fetal death occur at 26 weeks of gestation. The patient who is RhD negative, suffers anti-D inmunization with a antibody titration of 1/1024 with 14 weeks of gestation. Twelve plasmapheresis, eight doses of anti-D inmunoglobulins and intrauterine transfusions has been the treatment received. A severe anemia is found during the ultrasound control of the middLe cerebral artery peak systolic velocity in both twins since the 16th week. It remains stable thanks to the treatment. Finally at the 28th week of gestation, pregnancy is terminated with a cesarean section. The twins are born alive and premature, but with good general state. The measurement of the middle cerebral artery peak systolic velocity predicts moderate-severe fetal anemia cases, which are the most important in the clinical management because of the need of active treatment or finish the pregnancy.
