In a study from Rotterdam (Jansen MAE, et al. Clin Gastroenterol Hepatol 2015; 13: 913-20), the authors show that positivity for anti-tissue transglutaminase IgA antibodies (TTG) is associated with lower growth trajectories and bone mineral density.
This was a population-based prospective cohort study which examined children born from 2002-2006 (median age 6 years). 4249 children with TTG <7 U/mL were compared with 57 children with TTG >7 U/mL. The authors specifically looked at those >70 U/mL as well. Children with a previous diagnosis of celiac disease were excluded.
- Positive TTG serology was associated with reduced weight gain 0.05 standard deviation score (SDS) per year and less linear growth 0.02 SDS/year.
- Children with positive TTG were shorter 0.29 SDS and weighed less 0.38 SDS.
- Children with positive TTG had lower bone mineral density (BMD) 0.26 SDS less.
- Children with positive TTG did not have increased gastrointestinal symptoms compared with control children.
The authors note that the majority of these effects (poor growth, shortness, lower BMD) were mostly present in children with TTG >10 times upper limit of normal.
Bottomline: Subclinical or potential celiac disease is associated with reduced growth and bone mineral density.
Briefly noted: Emilsson L, et al. Clin Gastroenterol Hepatol 2015; 13: 921-27. Using a Norwegian cohort study with 95,200 women and 114,500 children (199-2008), the authors showed that development of celiac disease was associated with maternal celiac disease and type 1 diabetes. There was no significant association noted with intrauterine growth, or mode of delivery.
