Pregnant women who take antidepressant medications during pregnancy may face a higher risk of delivering their babies prematurely, according to a new study that stopped short of declaring a direct link between the two. More from The New York Times:
Researchers reviewed data from 41 studies, some of which controlled for factors like smoking, alcohol or coffee drinking, weight gain during pregnancy, and other behavioral and health issues. They found no increase in the risk of early birth with the use of antidepressants during the first trimester, a 53 percent higher risk over all and a 96 percent higher risk with antidepressant use late in pregnancy.
Depression itself is a risk factor for premature births, and a few studies tried to account for this by using, as a control, a group of women with a diagnosis of depression who did not take antidepressants during their pregnancy. Generally, researchers still found a higher, though diminished, risk from taking antidepressants. The review was published in March in PLOS One.
Does this mean that all pregnant women should avoid these drugs? No, said the senior author, Dr. Adam C. Urato, an assistant professor of maternal-fetal medicine at Tufts University. Risks and benefits have to be balanced, he said.
“It’s very complex, and depends on the severity of the disease,” Dr. Urato added. “The point is that we have to get the right information out so that we can let pregnant women make an informed decision.”

Babies born to mothers who took antidepressants during pregnancy are not any more likely to develop an autism spectrum disorder (ASD) than babies born to mothers who didn’t take the medication. More from Reuters:
Women who take a common type of antidepressant during pregnancy are not more likely to have a child with autism, according to a new study from Denmark.
But children did have a higher than usual risk when their mothers took the drugs – known as selective serotonin reuptake inhibitors (SSRIs) – for depression or anxiety before becoming pregnant.
That suggests a possible link between a mother’s preexisting mental health issues and the developmental disorder that hinders social and communication skills.
“Our interpretation is that women with indications for SSRI use differ from women who do not use SSRIs because of these indications (depression, anxiety), and some of these differences are somehow related to an increased risk of having children who develop autism,” Dr. Anders Hviid said. He led the study at the Statens Serum Institute in Copenhagen.
“Whether these differences are genetic, social or something completely different is speculation at this point,” Hviid said.
The findings, combined with a separate analysis of the same database published last month in the journal Clinical Epidemiology, suggest people looking for a link between autism and SSRIs need to look elsewhere, Dr. Mark Zylka said.
Zylka, from the University of North Carolina at Chapel Hill School of Medicine, has studied autism but was not involved in the analyses.
“There’s been a big question in the literature about whether these drugs affect brain development in any way and cause autism,” he told Reuters Health. That’s important because of how many people take antidepressants, including pregnant women.

A new report from the American Academy of Pediatrics (AAP) finds that breastfeeding women can safely use many medications without harming their infants.
Experts from the AAP Committee on Drugs also noted that some doctors give moms inaccurate advice that they must quit nursing or stop taking certain medicines to keep their babies safe. From Reuters:
“Sometimes people are told that, because physicians may be worried about the risks the drug may pose … and aren’t necessarily thinking about the potential benefit of breastfeeding,” Dr. Hari Cheryl Sachs, the lead author on the report, said.
That benefit includes a lower risk of ear infections, asthma and sudden infant death syndrome, according to the U.S. Department of Health and Human Services.
Sachs said properties of the drug itself, whether it’s being used on a long- or short-term basis and the age and health of the infant all affect how safe it is to use medication while breastfeeding.
“It’s hard to make a blanket recommendation on what drugs are fine for the mother, because it’s going to depend on multiple factors,” Sachs, from the Pediatric and Maternal Health Team in the Food and Drug Administration’s Center for Drug Evaluation and Research, told Reuters Health.
If breastfeeding women have questions about specific medications, Sachs recommends that they talk with their doctors and check LactMed, a website run by the National Institutes of Health. Again from Reuters:
[LactMed] includes the most up-to-date scientific knowledge on how much of a given drug is passed to an infant during breastfeeding, its effects on babies and possible alternatives to consider.
In its report, published Monday in Pediatrics, the committee focused on a few classes of drugs, including antidepressants, narcotics and smoking cessation aids.
Limited information is available on the long-term effects of antidepressants on babies, it wrote, and because the drugs take a long time to break down, levels could build up in infants’ bodies.
“Caution is advised” for certain powerful painkillers such as codeine and hydrocodone—but others including morphine are considered safer when used at the lowest possible dose and for the shortest possible time, pediatricians said.
Nicotine replacement therapy, especially gum and lozenges, is typically considered safe to use during breastfeeding, according to the committee. However the FDA discourages the use of stop-smoking drugs such as varenicline, marketed in the U.S. as Chantix, among women who breastfeed.
The risk of exposure to any drug for babies needs to be weighed against the drug’s importance for the mother as well as the benefits of breastfeeding, researchers noted.

A new study has found that a mother who suffers from depression during pregnancy may expect to see some language delays in her baby. The study, which was published in the journal Proceedings of the National Academy of Sciences, tested babies at ages 6 months and 10 months, each time measuring the babies’ abilities to distinguish between similar sounds in different language, and engage with people who are speaking different languages when the speakers’ voices are muted.
In typically developing children, 6-month-olds can easily make distinctions between two languages, and 10-month-olds cannot, revealing a critical window for language development in young brains. The study, however, found that babies whose mothers were depressed but took no medication during pregnancy experienced a delay; they “passed the test” at 10 months, but failed it at 6 months. Babies whose mothers took antidepressants during pregnancy failed the test at both ages.
CNN.com has more:
“What’s going on here? Researchers aren’t sure, and they don’t know if it’s good or bad. One explanation for delay in the depressed-but-not-medicated group is that those kids weren’t being exposed to as much engaging speech because their mothers were depressed.
Alternatively, the brain chemicals from the mother associated with depression could have something to do with it. And the antidepressants could be impacting the child’s brain development in the group whose mothers took these medications.
Are there long-lasting consequences of delays, or advancements, in this critical period of language sensitivity? No one knows. More research needs to be done in order to determine the implications of the findings of this study.”

A new review of published and unpublished research is raising questions about whether certain antidepressants can help children with autism spectrum disorders (ASD) control repetitive behaviors and manage other symptoms. Reuters reports:
The drugs, which include popular selective serotonin reuptake inhibitors (SSRIs), are sometimes used to treat repetitive behaviors in people with obsessive-compulsive disorder (OCD).
“The main issue to emphasize is that SSRIs are perhaps not as effective at treating repetitive behaviors as previously thought. Further research will help confirm these findings in the long run,” said Melisa Carrasco, the study’s lead author, in an email.
For their analysis, Carrasco, a researcher at the University of Michigan in Ann Arbor, and her colleagues examined PubMed and ClinicalTrials.gov for randomized, double-blind and placebo-controlled trials — considered the gold standard in medical research — supporting the use of SSRIs and similar antidepressants in children with autism.
