Abstract

Context: Information regarding the impact of parental multiple endocrine neoplasia type 1(MEN 1) on neonatal outcomes is limited to case reports.Objective: To determine the impact of parental MEN 1 on neonatal outcomes.Methods: Retrospective cohort analysis of the Tasman 1 MEN 1 kindred stratified by whetherbirth occurred before (“historical cohort”) or after (“contemporary cohort”) prospectivescreening commenced. The historical cohort included kindred members born between 1825 and1984 (n = 341 children with a MEN 1 positive (MEN 1+) parent and n = 314 children with MEN1 negative (MEN 1–) parents). The contemporary cohort included neonates (n = 52) of MEN 1+women (n = 21) managed at a tertiary referral hospital between 1985 and 2018.Results: Historical cohort: compared with MEN 1– parents, children of MEN 1+ parents weremore likely to die postpartum (HR 4.6, P = .046 at 6 months of age). Excess mortality at 15 yearsof age was observed for children of MEN 1+ mothers (HR 8.50, P = .002) and fathers (HR 3.82,P = .03). Contemporary cohort: neonates of MEN 1+ mothers were more likely to have low birthweight (28.9% vs 6.7%, P = .01), be admitted to a higher care nursery (40.4% vs 17%, P = .02),and require a longer median postnatal stay (5 vs 4 days, P = .009) than the Australian average.Isolated antenatal hypercalcemia did not significantly alter neonatal outcomes.Conclusion: Children with a MEN 1+ parent are disproportionately vulnerable postpartum. Neonates ofMEN 1+ mothers remain vulnerable despite contemporary care. The excess risk was not fully explainedby maternal MEN 1 or antenatal hypercalcemia.
