Background: The incidence of congenital syphilis is increasing worldwide, in parallel with the increase of syphilis in the general population. Objectives: This study aimed to determine the incidence and risk factors for congenital syphilis at a referral tertiary care center in Bangkok, Thailand. Methods: This is a case–control study using the hospital medical records of neonates born at our hospital, whose mothers had confirmed syphilis during pregnancy or at delivery between 2011 and 2018. Maternal and neonatal data were reviewed. Neonates were categorized into congenital syphilis according to CDC surveillance case definition for congenital syphilis 2015 and the American Academy of Pediatrics Congenital Syphilis 2018: confirmed and probable were assigned to the case group, while possible and less likely congenital syphilis were used as the control group. Factors associated with congenital syphilis were analyzed using univariable and multivariable analysis. Results: Among 19,558 live births, there were 126 neonates born to mothers with syphilis. Almost 40% of mothers were teenage mothers and 48.4% had inadequate or no syphilis treatment. Forty neonates met the criteria of congenital syphilis giving the incidence of 204 per 100,000 live births (95% confidence interval [CI]: 146–278). Factors associated with congenital syphilis were inadequate treatment of maternal syphilis and preterm birth (adjusted odd ratio [aOR]: 2.69, 95% CI: 1.02–7.11, P = 0.046 and aOR: 2.91; 95% CI: 1.01–8.39, P = 0.049, respectively). Conclusions: The incidence of congenital syphilis in our institution was high. Factors associated with congenital syphilis were inadequate treatment of maternal syphilis and preterm birth. Improvement of prenatal care should be emphasized.
BackgroundAcute liver failure (ALF) is a rare condition during neonatal period.ObjectiveTo report a case of recipient twin with fulminant ALF secondary to hydrops fetalis caused by twin-to-twin transfusion syndrome (TTTS).MethodThe patient was admitted to the neonatal intensive care unit (NICU) for respiratory failure requiring mechanical ventilation and fulminant ALF with prolonged international normalized ratio (INR) and elevated liver enzymes with highest aspartate aminotransferase of 4,580 U/L.ResultsLaboratory investigation for secondary causes of liver failure was not revealing. Her liver enzymes and coagulation levels were dramatically normalized as the clinical symptoms of hypervolemia improved within 1 week.ConclusionTTTS can be a possible cause of neonatal ALF. Early detection with proper management of TTTS is important to avoid adverse outcomes. However, pathogenesis of hepatic dysfunction in TTTS is rarely described, and further studies are needed to help understanding the correlation between liver diseases and TTTS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
