title: Pregnancy outcome after maternal organ transplantation in Sweden.
abstract: OBJECTIVE
  To study pregnancy outcome before and after organ transplantation.
  
  
  METHODS
  Registry study.
  
  
  METHODS
  Swedish Health Registers.
  
  
  METHODS
  All births in Sweden 1973-2002.
  
  
  METHODS
  Women who had organ transplantation were identified from the Hospital Discharge Register and their deliveries before and after the transplantation were identified from the Medical Birth Register. Abortions requiring hospitalisation were identified from the Hospital Discharge Register. Outcomes were compared with those in the total population. Adjustments were made for maternal age, parity and smoking habits.
  
  
  METHODS
  Miscarriage, preterm delivery, low birthweight, small for gestational age, congenital malformations, infant death, pre-eclampsia and placental abruption.
  
  
  RESULTS
  A total of 980 infants born before and 152 born after transplantation were identified. A high frequency of pre-eclampsia (22%), preterm birth (46%), low birthweight (41%), small for gestational age (16%) and infant death (5% before the age of one) were found for deliveries after transplantation but similar frequencies were found also among deliveries a few years before transplantation. No significant increase in congenital malformation rate was seen. Among 15 infants born after liver transplantation, 2 were malformed.
  
  
  CONCLUSIONS
  Pregnancies after organ transplantation have an increased risk of complications but this is similar to pregnancies occurring before the transplantation.
