Maternal celiac disease: improbable risk factor for neural tube defect

Area of Science:

• Obstetrics and Gynecology
• Pediatrics
• Immunology

Background:

• Maternal celiac disease (CD) has been anecdotally linked to adverse pregnancy outcomes.
• Neural tube defects (NTD) are serious congenital anomalies with multifactorial causes.
• Previous literature suggested a potential association between CD and NTD, warranting further investigation.

Purpose of the Study:

• To determine if there is a correlation between maternal celiac disease and the occurrence of neural tube defects in newborns.
• To assess the prevalence of celiac disease markers in mothers experiencing NTD-affected pregnancies.

Main Methods:

• Serological testing was conducted on 208 mothers with NTD-affected pregnancies.
• Tests included total serum immunoglobulin A (IgA) levels and IgA class endomysial antibody detection via indirect immunofluorescence.
• Participants' ages ranged from 19 to 43 years; none had prior CD investigation or family history.

Main Results:

• All tested women had normal immunoglobulin A levels.
• IgA class endomysial antibody tests were negative in all participants.
• No serological evidence of celiac disease was found in mothers with NTD-affected pregnancies.

Conclusions:

• The study did not corroborate previous findings suggesting an increased frequency of CD in mothers with NTD-affected pregnancies.
• Current evidence does not support routine CD screening in pregnant women to prevent NTD.
• Further research may be needed to definitively rule out any association.
