Background Neonatal abstinence syndrome (NAS) in infants of methadone-maintained opioid-dependent (MMOD) mothers cannot be predicted in individual cases. We investigated whether variation in infant genotype is associated with severity of NAS. Methods This is a pilot observational cohort study of 21 MMOD mothers and their newborns. Infant buccal swabs were obtained soon after delivery, together with a maternal blood sample for the determination of maternal plasma methadone concentration. Genomic variation in five opioid-related genes (ABCB1, COMT, CYP2B6, CYP2D6, and OPRM1) was ascertained from infant buccal swabs and related to need for pharmacological treatment of NAS. Results Out of 21 infants, 11 (52%) required treatment for NAS. Mothers of treated infants tended to have been prescribed higher doses of methadone, but plasma methadone concentrations did not differ between mothers of treated or untreated babies. Treated and untreated babies did not differ in terms of method of feeding. Treated infants were more likely to carry the normal (homozygous) allele at 516 and 785 regions of CYP2B6 gene (p = 0.015 and 0.023, respectively). There were no differences in any other genes between infants who did or did not require treatment for NAS. Conclusion Genomic variation in CYP2B6 may explain, at least in part, severity of NAS.

Objective: To determine whether pharmacological treatment for neonatal abstinence syndrome (NAS) is associated with changes in DNA methylation (DNAm) of the mu-opioid receptor gene (OPRM1) and improvements in neonatal neurobehavior.Study Design: Buccal swabs were collected from 37 neonates before and after morphine treatment for NAS. Genomic DNA was extracted and DNAm was examined at four CpG sites within the OPRM1 gene. The NICU Network Neurobehavioral Scales (NNNS) was also performed before and after NAS treatment. Changes in DNAm (DNAmpost-tx – DNAmpre-tx) and NNNS summary scores (NNNSpost-tx – NNNSpre-tx) were then calculated. Path analysis was used to examine associations among pharmacologic treatment (length of treatment and total dose of morphine), changes in DNAm, and changes in NNNS summary scores. Results: DNAm significantly decreased from pre- to post-treatment at 1 of 4 CpG sites within the OPRM1 gene. Neonates also demonstrated decreased excitability, hypertonia, lethargy, signs of stress and abstinence, and increased quality of movement and regulation from pre- to post-treatment. Increased length of treatment and higher morphine doses were associated with greater decreases in DNAm; greater decreases in DNAm were associated with greater decreases in excitability and hypertonia on the NNNS.Conclusions: Pharmacological treatment of NAS is associated with decreased DNAm of the OPRM1 gene and improved neonatal neurobehavior. Epigenetic changes may play a role in these changes in neonatal neurobehavior.

Objective The practice of rooming-in for opioid-dependent infants was introduced as the standard of care at our hospital following a pilot study which demonstrated that such infants had shorter lengths of stay and were less likely to require pharmacological treatment. We sought to determine whether these benefits have continued, and whether outcomes support continuing to use rooming-in as standard care. Study Design Opioid-dependent infants delivered at 36 weeks gestation or later between January 1, 2015, and December 31, 2019, were eligible for rooming-in. Charts were reviewed and data were extracted regarding maternal and infant conditions, whether neonatal pharmacological treatment was required, and total length of hospital stay. Outcomes were compared with two historical groups reported in a previous pilot study: 24 healthy near-term opioid-dependent newborns who were admitted directly to the neonatal intensive care unit (NICU) prior to the introduction of rooming-in (May 1, 2012–May 31, 2013), and 20 similar opioid-dependent infants who were the first to room-in at our hospital (September 1, 2013–September 30, 2014). Results Only 3.5% of 57 infants who roomed-in during the 5-year study period required pharmacological treatment, compared with 15% who roomed-in during the first year of the program's introduction and 83.3% who had been admitted directly to the NICU. The median length of stay remained 5 days for infants rooming-in, compared with 24 days for opioid-dependent infants in the cohort admitted to the NICU. Conclusion Early observations of the benefits of rooming-in on neonatal outcomes were sustained. Infants allowed to room-in were significantly less likely to require initiation of pharmacotherapy and a prolonged hospital stay than similar infants prior to the implementation of rooming-in as standard care. A large proportion of the infants who might have benefited from rooming-in required admission to the NICU for reasons other than neonatal abstinence syndrome (NAS). Key Points
