ECHO Study Suggests Exposure to Opioids During Pregnancy May Have Subtle Effects on Child Health Outcomes

Author(s): Elisabeth Conradt, Sheila Crowell and Barry Lester 

 

Who sponsored this study?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) program, Office of The Director, National Institutes of Health.

 

What were the study results?

We were not able to learn what the short and long-term results of prenatal opioid exposure were because of the limitations with the existing information. Our best working hypothesis is that the effects of prenatal opioid exposure at birth and in infancy are small and subtle, but that the effects may grow as children age and have more demands on their attention at home and at school.

 

What was the study's impact?

We are still trying hard to learn about the short and long-term developmental effects of prenatal opioid exposure. We think that the effects of prenatal opioid exposure at birth and in infancy are subtle, and that they could be also be caused by the effects of other things such as poverty and early life stress. The effects in childhood may be stronger, but they could also be due to long-term stress exposure. More high-quality research is needed to answer the question, “how does prenatal opioid exposure affect the child?”

 

Why was this study needed?

We have very little information about how a mother’s use of opioids during pregnancy (prenatal opioid exposure) can affect child development. The information we have thus far is limited by not having many people to study and not being able to study other factors that may have an effect on child development, such as poverty. For this study, we reviewed what information we know so far and also made suggestions for how to improve knowledge of prenatal opioid exposure.

 

Who was involved?

This publication was a review of information that had already been published. After review, we came together as a group and decided what should be done next to answer the question, “how does prenatal opioid exposure affect the child?”

 

What happened during the study?

We reviewed over 50 studies to try to come up with some answers about how being exposed to opioids during pregnancy affects a child over short and long periods of time. We then discussed the limitations of the study and developed a list of what can be done in the future to fix these limitations. We concluded by describing how ECHO can help provide more information about this research topic.

 

What happens next?

We will use the ECHO data that are already collected to test how prenatal opioid exposure affects knowledge/understanding, behavior, and attention span in middle childhood. We will consider other possible factors such as poverty. We will also look at whether newborns who have Neonatal Abstinence Syndrome/Neonatal Opioid Withdrawal Syndrome (NAS/NOWS) have worse effects compared to newborns exposed to opioids who do not have NAS/NOWS.

ECHO Study Suggests Specific Form of Vitamin E Prevents, Treats Bronchopulmonary Dysplasia

ECHO Study Suggests Specific Form of Vitamin E Prevents, Treats Bronchopulmonary Dysplasia

Author(s): Cosby Stone, Cynthia McEvoy, Judy Aschner, et al  

 

Who sponsored this research?

This research was supported by the Environmental influences on Child Health Outcomes (ECHO) program, Office of The Director, National Institutes of Health.

 

What were the study results?

The researchers learned:

  • There was not enough information in existing studies to recommend using vitamin E to prevent BPD.
  • A specific type of vitamin E called α-tocopherol isoform may be helpful in preventing or treating BPD.

*Results reported here are for a single research review. Other or future reviews or studies may provide new information or different results. You should not make changes to your health without first consulting your healthcare professional.

 

What was the study's impact?

The researchers think that studying the vitamin E α-tocopherol isoform would help provide more information on the benefits and risks of using it to prevent and treat BPD. This type of vitamin E is already associated with better health outcomes for conditions such as asthma, allergic airway swelling, and improved lung growth than other forms of vitamin E. However, without further studies, there is not enough information to recommend it now.

 

Why was this study needed?

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that mostly affects newborns and infants. It occurs when a newborn or infants’ lungs are damaged from being on a ventilator (a machine that provides oxygen). We already know that there is a connection between low levels of vitamin E and the risk of BPD. Some doctors use vitamin E to help prevent BPD in newborns and infants. However, the last time researchers studied how vitamin E may affect BPD was 1991. Since then, we have learned more about how to reduce the risk of oxygen and ventilator-related lung injuries in newborns. We also know more about how vitamin E affects overall lung health. People only get vitamin E through their diet or supplements, like vitamins, so it’s important to understand if people need more of it.

 

What was the purpose of the study?

To update our knowledge and understanding of vitamin E and BPD.

 

Who was involved?

No study participants were involved in this research.  The researchers involved are experts in neonatology (the study of newborns), epidemiology (understanding health in certain populations of people), pulmonary medicine (medicine related to the lungs) and environmental interventions (how changing something in a person’s environment affects health.

 

What happened during the study?

Researchers gathered and analyzed existing research on vitamin E. From this analysis, they suggest ideas for future research that could help us learn more about vitamin E and its role in preventing or treating BPD.

 

What happens next?

Researchers are interested in studying individual types of vitamin E as dietary supplements to improve lung health and as a potential way to treat or prevent BPD. We will need more and better data from research studies to understand if taking certain vitamin E isoforms can help reduce the risk of:

  • BPD for newborns when taken by a pregnant women at risk of preterm birth.
  • BPD for premature newborn when given to the newborn right after birth.
  • Having long-term lung problems that may continue later into life.
