The prevalence of mood disorders (anxiety and depression) during pregnancy seems to be similar to the women of the same group without pregnancy. Women with recurrent depression and euthimic women who discontinued antidepressants medication during pregnancy are particularly at high risk for depressive illness. Data about perinatal effects of SSRI antidepressants are gradually accumulating and are controversial. Two meta-analyses and some controlled studies don't find increased risk for major malformations in SSRI-exposed newborn. However, other studies find an increased risk of congenital malformations, poor birth outcomes and neonatal complications.

Neonatal morbidity in infant newborn of women treated with antidepressant drugs.

We examine the relation between the pharmacological treatment of the maternal anxiety/depression during the pregnancy and acute morbidity in infant newborns.

Study group of 66 infant newborn of pregnant women with a diagnoses of major depressive episode or defined anxiety disorders according to DSM-IV, who were in treatment with antidepressant drugs during pregnancy. Control group: 120 newborn of healthy pregnant women, who did not receive any treatment, and were contemporary of the same gestational age and sex. Criteria of exclusion: demonstrated toxic consumption (alcohol, cocaine, cannabis, opiates, drug of synthesis). Studied variables: Type of childbirth and analgesia; weight and age of gestation; pH of umbilical artery and Apgar test; presence of malformations; morbidity; feeding; withdrawal syndrome.

Infant newborn of mothers exposed to the antidepressant treatment suffered from more pathology than those of the control group (16/66 vs. 14/114; 24.2% vs.12.3%; p=0.038). Two smaller malformations in the study group were observed, a preauricular appendix (group A) and one moderate pielocilicilar ectasy (group C), both in mothers who received paroxetine (2/60; 3.3% vs. 0/114; 0%, p=0.05, Fisher p=0.118, NS). Only one infant newborn displayed compatible clinical signs with moderate withdrawal syndrome (irritability, vomits) from a mother treated with venlafaxine. No case of convulsions was observed. Breast feeding was less frequent in the group of antidepressant treated mothers (38/66, 57.6% vs. 86/116, 74,1%, p=0.032).

The treatment with antidepressant drugs during pregnancy is necessary for some women. The clinician must weigh the relative risks of various treatment options and take into account individual patient wishes. Although the antidepressant drugs suppose an increased risk for the newborn, it could be assumable for the benefit that represents maintain the mother in an euthimic situation.

We propose to discuss the clinical management, as well as, the accuracy of the psychiatric and obstetric controls to minimize the neonatal complications.
