title: [Evaluation of the effectiveness of a low-dose aspirin in the treatment of intrauterine growth retardation (IUGR)].
abstract: OBJECTIVE
  To evaluate the benefits of IUGR treatment by low doses of acetylsalicylic acid (ASA) (1.5 mg/kg) compared to the standard method. The study was based on the reports that aspirin at low doses shifts prostacyclin/tromboxan A2 balance to the dominance of prostacyclin by inhibiting cyclooxygenase activity in platelets, which results in the improvement of the utero-placental circulation.
  
  
  METHODS
  31 pregnant women with diagnosed fetal IUGR were randomly assigned to two groups, receiving either low-dose ASA (n = 22) or the standard treatment (Sadamin, Partusisten, glucose i.v., amino acids i.v.) for 10 days. Ultrasound examination of the biometric parameters of the fetus (BPD, AC, FL) was performed and estimated fetal weight (EFW) calculated before and after treatment. The birthweight of infants in the two examined groups was compared.
  
  
  RESULTS
  The mean increase in EFW was higher in the aspirin-treated group compared to that receiving standard treatment (478 g vs 246 g, p < 0.05). In all the biometric parameters under study a higher increase was noted in the group with aspirin treatment; however, the difference was not statistically significant. The mean birthweight was found to be higher in the ASA group as well (2856 g vs 2511 g). The frequency of small-for-gestational-age (SGA) infants (birth weight below 10th percentile) was lower in the ASA group than in the controls (27% vs 55%). The low-dose aspirin therapy did not produce any adverse side-effects either among mothers of infants.
  
  
  CONCLUSIONS
  The treatment with low doses of aspirin reduces the proportion of SGA babies and increases birthweight in the case of a diagnosed fetal growth retardation. Since the number of subjects in this study was relatively small, further clinical trials are necessary to evaluate the effectiveness of IUGR treatment by low-dose aspirin.
