Summary
Multivitamin supplementation during early pregnancy may help prevent cleft lip and palate, but research findings are controversial. Further animal studies are needed to clarify the prophylactic effects of vitamins and other substances.
Area of Science:
- Medical Genetics
- Developmental Biology
- Teratology
Background:
- Cheilognathopalatoschisis (cleft lip, -maxilla, and -palate) is a common human malformation with multifactorial causes.
- Previous studies suggest potential prophylactic effects of multivitamin therapy during early pregnancy for cleft prevention, but dosages and efficacy remain unclear.
Purpose of the Study:
- To review and compare results from animal experiments investigating the prophylactic efficacy of vitamins and other substances in preventing clefts.
- To provide insight into the controversial findings regarding the protective effects of these interventions.
Main Methods:
- Review of animal experimental studies, primarily using rats and mice.
- Analysis of studies where clefts were induced by chemical agents (noxa).
- Comparison of reported protective effects versus lack of prophylactic efficacy.
Main Results:
- Experimental results on the prophylactic effects of vitamins and other substances are controversial.
- Some studies report protective effects, while others find no prophylactic benefit.
- The dosage and specificity of tested substances in previous trials were often anecdotal and unspecific.
Conclusions:
- The efficacy of vitamin and substance supplementation as a prophylactic measure against clefts requires further investigation.
- Animal models provide a platform for studying cleft prevention, but results are inconsistent.
- Clarifying the role and optimal application of prophylactic therapies is crucial for reducing cleft incidence.
