Does Antibiotic Exposure in Pregnancy Increase Risk of Celiac Disease in Offspring?

Celiac.com 08/27/2014 - Can antibiotic exposure in pregnancy increase the risk of celiac disease in children? Some researchers suspect that infant microbiota play a pathogenic role in celiac disease. The idea that antibiotic treatment in pregnancy could significantly impact the infant microbiota, and thus influence the development of celiac disease, has led many to ponder the possible connection.

Photo: CC--Kelly HunterTo get a clearer picture, a research team recently set out to study the effects on offspring of antibiotic exposure in pregnancy.

The team included Karl Mårild, Johnny Ludvigsson, Yolanda Sanz, and Jonas F. Ludvigsson. They are variously affiliated with the Deptartment of Medical Epidemiology and Biostatistics, Karolinska Institutet in Stockholm, the Astrid Lindgren Children's Hospital at Karolinska University Hospital in Solna, Sweden, the Division of Paediatrics in the Department of Clinical and Experimental Medicine at Linköping University, Östergötland County Council in Linköping, Sweden, the Department of Paediatrics of Örebro University Hospital in Örebro, Sweden, and the Microbial Ecology and Nutrition Research Group at the Institute of Agrochemistry and Food Technology of the National Research Council (IATA-CSIC) in Valencia, Spain.

The team started by reviewing existing data on antibiotic exposure in pregnancy in 8,729 children recorded in the All Babies in Southeast Sweden (ABIS) cohort study. Through December 2006, 46 of the 8,729 had developed celiac disease. The team then used Cox regression to estimate celiac disease hazard ratios (HRs) in children whose mothers received antibiotics during pregnancy. The ratios were adjusted based on parent-reported diary data on breastfeeding, age at gluten introduction, and the number of infections in the child's first year of life.

Of the 1,836 children exposed to antibiotics during pregnancy, 12 (0.7%) children developed celiac disease as compared with 34/6893 (0.5%) unexposed children (HR = 1.33; 95% CI = 0.69–2.56).

Risk estimates remained unchanged after adjustment for breastfeeding, age at gluten introduction and infection load in the child's first year of life (HR = 1.28; 95% CI = 0.66–2.48).

When all the data were factored, the team found no statistically significant connection between antibiotic exposure during pregnancy and celiac disease in offspring. The team suggests that this data may present an accurate picture, or it may be that they simply lack the statistical power to make a clear connection.

Further studies are likely needed before researchers can confidently conclude that there is no connection between antibiotic exposure in pregnancy and celiac disease in offspring.

Celiac Disease isn't something you catch. It isn't something you develop. Celiac disease is a GENETIC MUTATION! If you have the genes for deliac disease YOU HAVE IT. PERIOD! If you do not have the genes for Celiac Disease YOU DO NOT HAVE IT. PERIOD! Very ferkin simple. Antibiotics don't cause it, vaccinations don't cause it, smog doesn't cause it. YOUR GENES CAUSE IT!!! Stop wasting money researching what causes this when we know what causes it GENETICS. Use the research money wisely and find a way to treat us!

You are mistaken. Having the genetic markers for it does not mean that you will have celiac disease. Over 20% of the population in the USA have the generic markers for celiac disease, yet only around 1% have it.

Infants are born with a sterile gut, an all GI flora are acquired through environmental exposure. It wouldn't make sense that antibiotic exposure in utero would have any bearing on the subsequent acquisition of gut flora.

Very interesting. Hope to read more about it in the future.

Thanks Ennis!

There is light at the end of the tunnel. Like GFinDC said, the recovery time after a gluten exposure can vary due to so many different variables. I hope your recovery is fast! ?

Welcome to the forum. Thank you for sharing your story. I am sorry that you have had to suffer for so long. Celiac disease is so frustrating and still people (and that includes medical) are not aware if it. Thank goodness for that home test kit. I hope your recovery is swift! Please f...

Hi Arduaine, Welcome to the forum! Glutenings can cause different symptoms in people. When you are new to the gluten-free diet and early in the recovery, they may cause more intense symptoms than later. Most likely because your immune system is already in a heightened state of alert f...
