Insights
Gestational diabetes mellitus diagnosed early in pregnancy may contribute to orofacial clefts in newborns. Maintaining healthy habits and screening for diabetes before and during pregnancy are recommended for expectant mothers.
Area of Science:
- Obstetrics and Gynecology
- Pediatrics
- Endocrinology
Background:
- Metabolic disorders during pregnancy, such as diabetes mellitus, are recognized risk factors for congenital birth defects, including orofacial clefts (OFCs).
- While diabetes affects approximately 10% of pregnancies globally, its prevalence is lower in Romania (less than 5%).
- Maternal obesity and diabetes significantly increase the risk of craniofacial defects in offspring, suggesting complex pathogenic mechanisms.
Observation:
- A case report details a 4-day-old male newborn presenting with neonatal hypoglycemia, cleft lip, and symmetric macrosomia.
- The infant's mother, a 35-year-old Caucasian woman, had no significant personal risk factors or prior history of diabetes mellitus.
- Gestational diabetes mellitus was diagnosed at 10 weeks of gestation via a glucose tolerance test.
Findings:
- The diagnosis of gestational diabetes mellitus early in pregnancy (10 weeks), coupled with sustained hyperglycemia, is implicated as a potential cause of orofacial clefts.
- Fetal overgrowth, evidenced by macrosomia at birth, is also indicated as a contributing factor to the development of OFCs in this case.
- The study highlights the link between maternal metabolic status and fetal development, specifically concerning craniofacial anomalies.
Implications:
- Given the rising prevalence of obesity and diabetes, and their association with OFCs, preconception and early pregnancy screening for diabetes is crucial.
- Mothers planning pregnancy should be advised on adopting healthy lifestyle habits and maintaining a healthy weight to mitigate risks.
- This case underscores the importance of early detection and management of gestational diabetes mellitus to prevent adverse birth outcomes.
Background:
Several studies observed metabolic disorders in pregnancy as risk factors for birth defects, including orofacial clefts. Diabetes is associated with approx. 10% of the pregnancies, but in Romania, less than 5%. An obese and diabetic woman has 3 times more risk for an offspring with a craniofacial defect than healthy women suggesting that diabetes mellitus contributes to their pathogenesis with complex mechanisms.
Case Report:
We present the case of a newborn 4 days old, male with neonatal hypoglycemia, cleft lip and proportionate (symmetric) macrosomia. His mother is a 35 years old Caucasian woman with no important personal risk factors and no known history of diabetes mellitus. The glucose tolerance test performed to the mother at about 10 weeks during pregnancy led to the diagnosis of gestational diabetes.
Discussion:
The gestational diabetes mellitus diagnosed since the 10th week of pregnancy, the hyperglycemia status during pregnancy and the fetal overgrowth (macrosomia at birth) indicate the possible factors that lead to the Orofacial cleft (OFC).
Conclusion:
With the increased prevalence of obesity, diabetes, and the evidence of association of these syndromes with OFCs, it is recommended that mothers planning to become pregnant to follow healthy habits, maintain healthy weight, and be screened for possible diabetes prior to conception and early in pregnancy.
