Congenital anomalies in multiple births after early loss of a conceptus
Background Congenital anomalies are more common in twins than singletons but in the majority, aetiology is not known. Our aim was to test the hypothesis that survivors of an early loss in a multiple conception, compared with all singletons, are at increased risk of congenital anomaly. Methods Data w...

Methods Data were abstracted from the UK population-based Northern Multiple Pregnancy Register and Northern Congenital Abnormality Survey, 1998–2004. Results Among 3311 twin conceptions, both conceptuses were lost at <16 weeks gestation in 67, and one conceptus in 142 conceptions. Of the 142 singleton survivors, two died in infancy, two were terminated for a congenital anomaly and 11 of 138 had a congenital anomaly (prevalence 915.5 per 10 000 births). There were 197 congenital anomalies among 5948 registered twin births (331.2 per 10 000). The relative risk (RR) of congenital anomalies in a singleton with early loss of a conceptus and twins was 2.40 [95% confidence interval (CI): 1.34–4.29]. There were 4265 infants with a congenital anomaly among the 206 914 singletons [206.1 per 10 000 births: RR twin:singleton 1.61 (95% CI 1.40–1.89)]. Conclusions A highly significant increase in the risk of congenital anomaly in survivors from a multiple conception following early loss of a conceptus supports the hypothesis that many congenital anomalies are associated with monozygotic multiple conceptions.</description><identifier>ISSN: 0268-1161</identifier><identifier>EISSN: 1460-2350</identifier><identifier>DOI: 10.1093/humrep/den436</identifier><identifier>PMID: 19059945</identifier><identifier>CODEN: HUREEE</identifier><language>eng</language><publisher>Oxford: Oxford University Press</publisher><subject>Abortion, Spontaneous ; Biological and medical sciences ; Congenital Abnormalities - diagnosis ; Congenital Abnormalities - epidemiology ; congenital anomalies ; Diseases in Twins - etiology ; early fetal loss ; England ; Female ; Gestational Age ; Gynecology.
