Abstract
Background
There are growing concerns regarding ocular and brain abnormalities in infants who had in utero exposure to various kinds of substances/drugs. We compared the ocular and brain abnormalities among neonates based on the type of drug used by mothers.
Methodology
This prospective cohort study of 305 neonates included all neonates at Mahdieh Hospital, Tehran, Iran, who had their records for ophthalmic screening and brain sonography and were born to mothers with a history of substance use disorder (2014-2017). Demographic data, results for viral antibodies (human immunodeficiency virus, hepatitis C, and hepatitis B), and Apgar scores at one and five minutes were collected. We excluded neonates with Apgar score <8 at one minute, weight <1,800 g, gestational age <35 weeks, asphyxia, or anomalies. The neonates’ eyes were examined using tropicamide 0.5%, phenylephrine 2.5%, and tetracaine.
Results
The prevalence of substance use disorder among pregnant women was 1.8%. The study included 305 neonates with a mean gestational age of 37.8 ± 1.6 weeks, while the mean age of their mothers with substance use disorder was 29.8 ± 6.4 years. Ophthalmologic examination showed that 37 (12%) neonates had abnormal incomplete retina vascularization, and brain abnormalities were seen in 29 (9.5%) neonates; however, no difference was identified based on the type of drug used by mothers. The birth weight (BW) of the neonates depended on the type of drugs used by the mothers (p = 0.027). Maternal use of cannabis and amphetamine were associated with the lowest and highest BWs (2,800 ± 283 and 3,750 ± 42 g), respectively.
Conclusions
The BW of neonates depended on the type of drugs used by the mothers, where cannabis and amphetamine use were associated with the lowest and highest BWs, respectively. However, our data could not identify if neonates’ ocular and brain abnormalities differed based on the types of drugs. This study highlights the importance of a drug-free pregnancy and the need for addiction-prevention programs provided to women of childbearing age.
