Paroxetine and fluoxetine in pregnancy: a prospective, multicentre, controlled, observational study

AIMS Recent studies have suggested a possible association between maternal use of selective serotonin reuptake inhibitors (SSRIs) in early pregnancy and cardiovascular anomalies. The aim of the present study was to evaluate the teratogenic risk of paroxetine and fluoxetine. METHODS This multicentre, prospective, controlled study evaluated the rate of major congenital anomalies after first-trimester gestational exposure to paroxetine, fluoxetine or nonteratogens. RESULTS We followed up 410 paroxetine, 314 fluoxetine first-trimester exposed pregnancies and 1467 controls. After exclusion of genetic and cytogenetic anomalies, there was a higher rate of major anomalies in the SSRI groups compared with the controls [paroxetine 18/348 (5.2%), fluoxetine 12/253 (4.7%) and controls 34/1359 (2.5%)]. The main risk applied to cardiovascular anomalies [paroxetine 7/348 (2.0%), crude odds ratio (OR) 3.47, 95% confidence interval (CI) 1.13, 10.58; fluoxetine 7/253 (2.8%), crude OR, 4.81 95% CI 1.56, 14.71; and controls 8/1359 (0.6%)]. On logistic regression analysis only cigarette smoking of >or=10 cigarettes day(-1) and fluoxetine exposure were significant variables for cardiovascular anomalies. The adjusted ORs for paroxetine and fluoxetine were 2.66 (95% CI 0.80, 8.90) and 4.47 (95% CI 1.31, 15.27), respectively. CONCLUSION This study suggests a possible association between cardiovascular anomalies and first-trimester exposure to fluoxetine.

The safety of proton pump inhibitors in pregnancy: a multicentre prospective controlled study

Background : Proton pump inhibitors are used to treat gastro‐oesophageal reflux and peptic ulcers. Gastro‐oesophageal reflux is a common condition in pregnancy. Human pregnancy experience with lansoprazole or pantoprazole is very limited. More data exist on the safety of omeprazole in pregnancy.

Pregnancy outcome, thyroid dysfunction and fetal goitre after in utero exposure to propylthiouracil: a controlled cohort study.

AIMS Propylthiouracil (PTU) is presently considered to be the treatment of choice for hyperthyroidism in pregnancy. It is known to cross the human placenta, and therefore may affect the fetus. The major aims of this study were to evaluate the rate of major anomalies and to report the rate of fetal goitre, accompanied by hypothyroidism, in fetuses/ newborns of mothers after in utero exposure to PTU. METHODS Prospective observational controlled cohort study of PTU-exposed pregnancies of women counselled by the Israeli Teratology Information Service between the years 1994 and 2004 compared with women exposed to nonteratogens. RESULTS We followed up 115 PTU-exposed pregnancies and 1141 controls. The rate of major anomalies was comparable between the groups [PTU 1/80 (1.3%), control 34/1066 (3.2%), P= 0.507]. Hypothyroidism was found in 9.5% of fetuses/neonates (56.8% of whom with goitre). Hyperthyroidism, possibly resulting from maternal disease, was found in 10.3%. Goitres prenatally diagnosed by ultrasound were successfully treated in utero by maternal dose adjustment. In most cases neonatal thyroid functions normalized during the first month of life without any treatment. Median neonatal birth weight was lower [PTU 3145 g (2655-3537) vs. control 3300 g (2968-3600), P= 0.018]. CONCLUSIONS PTU does not seem to be a major human teratogen. However, it could cause fetal/neonatal hypothyroidism with or without goitre. Fetal thyroid size monitoring and neonatal thyroid function tests are important for appropriate prevention and treatment.

Pregnancy outcome after in utero exposure to colchicine

OBJECTIVE We sought to examine the fetal safety of colchicine. STUDY DESIGN This was a prospective observational comparative cohort study regarding colchicine exposure during pregnancy including contacts to 2 Teratology Information Services in Israel from 1994 through 2006. RESULTS In all, 238 colchicine-exposed pregnancies (97.0% first trimester) and 964 pregnancies with nonteratogenic exposure were followed up. Treatment indications were: familial Mediterranean fever (87.3%), Behçet disease (7.5%), or other (5.2%). The rate of major congenital anomalies was comparable between the groups (10/221 [4.5%] vs 35/908 [3.9%]; P = .648). There were no cytogenetic anomalies in the colchicine group. The median gestational age at delivery was earlier (39 [38-40] vs 40 [38-41] weeks; P < .001), the rate of preterm deliveries was higher (32/214 [15.0%] vs 51/867 [5.9%]; P < .001), and the median birthweight was lower (3000 [2688-3300] vs 3300 [2900-3600] g; P < .001) in the colchicine group. CONCLUSION The present study suggests that colchicine does not appear to be a major human teratogen, and, probably, has no cytogenetic effect.

Pregnancy outcome after in utero exposure to angiotensin converting enzyme inhibitors or angiotensin receptor blockers.

OBJECTIVE To examine first trimester safety of angiotensin-converting-enzyme-inhibitors (ACEIs) or angiotensin-receptor-blockers (ARBs). STUDY DESIGN Prospective observational cohort regarding pregnancy ACEI/ARBs-exposure including contacts to two Teratology Information Services in Israel (1994-2007) and Italy (1990-2008), with two comparison groups: (1) exposed to other antihypertensives (OAH) (2) after non-teratogenic exposure (NTE) in similar time frames. RESULTS 252 ACEI/ARBs-exposed, 256 OAH-exposed and 495 NTE-exposed pregnancies were followed-up. The rate of major congenital anomalies was comparable between the groups (8/190, 4.2%, ACEI/ARB; 9/212, 4.2%, OAH; 18/471, 3.8% NTE; p = 0.954) among first trimester exposed pregnancies. The median gestational age at delivery was two weeks earlier, rate of preterm deliveries more than 2-fold higher, and median birth weight more than 200 g lower in the ACEI/ARB and OAH groups compared to the NTE group. CONCLUSION The present study suggests that ACEI/ARBs are not major teratogens when used in the first trimester, and can reassure women with similar exposures.

Epstein–Barr virus infection in pregnancy—A prospective controlled study

BACKGROUND Epstein-Barr virus (EBV) is one of the most common human viruses. To date, there is limited information regarding the influence of maternal EBV infection on pregnancy outcome. OBJECTIVE Our aim was to examine the fetal safety of EBV infection in pregnancy. STUDY DESIGN We prospectively evaluated the rate of major anomalies and pregnancy outcome of women with serologic evidence of primary, recurrent or undefined infection (27, 56, and 43 women, respectively) compared to 1434 women who called the Israeli TIS for non-teratogenic exposure. RESULTS Womens characteristics and pregnancy outcome were comparable between the EBV exposed and control groups. Similarly, the gestational age at delivery and birth weight were not significantly different. The rate of major congenital anomalies did not significantly differ between the EBV exposed compared to the control group. CONCLUSION This study suggests that EBV infection during pregnancy does not represent a major teratogenic risk to the fetus.

Congenital fulminant Kaposiform hemangioendothelioma of the leg.

Kaposiform hemangioendothelioma is a rare locally aggressive vascular tumor associated with Kasabach Merritt syndrome. We present a case of congenital Kaposiform hemangioendothelioma of the leg in a female infant who was born to a mother treated with various medications including etanercept, a TNF antagonist, due to rheumatoid arthritis. The neonate suffered from a fulminant form of Kasabach Merritt syndrome with disseminated intravascular coagulation (DIC) resulting in multi-organ failure which led to her demise.
