title: Increased plasma levels of vasoactive intestinal polypeptide in pre-eclampsia.
abstract: OBJECTIVE
  To investigate the plasma vasoactive peptide (VIP) levels in pregnancies complicated by pre-eclampsia.
  
  
  METHODS
  A prospective clinical study.
  
  
  METHODS
  University Department of Obstetrics, Tromsø, Norway.
  
  
  METHODS
  18 women with untreated gestational proteinuric hypertension between 32 and 40 weeks gestation (13 primigravid) and 8 women with normal pregnancies of similar gestational age.
  
  
  METHODS
  Fasting blood samples on two occasions, 10 min apart.
  
  
  METHODS
  Plasma VIP measured by radioimmunoassay.
  
  
  RESULTS
  Mean maternal plasma VIP was 13.9 (SEM 1.7) pmol/l in those with pre-eclampsia and 4.4 (SEM 0.5) pmol/l in normal pregnancies (P less than 0.0001).
  
  
  CONCLUSIONS
  The increased levels of VIP in pre-eclampsia may represent a powerful compensatory mechanism to restore vascular perfusion of various organs, including the uterus and placenta.
