AIM: Elevated levels of anti-tissue transglutaminase (anti-tTG) antibody may spontaneously normalise in children with newly diagnosed type 1 diabetes, even if they eat gluten. The prevalence of this phenomenon and predictors of a subsequent coeliac disease (CD) diagnosis were determined.
METHODS: The medical records of children diagnosed with type 1 diabetes at Ha'Emek Medical Centre, Israel, from 2007 to 2015, were retrospectively reviewed for elevated anti-tTG antibody levels. Demographic, clinical, laboratory and histological findings were compared between CD patients and those with transient coeliac serology.
RESULTS: Of 425 patients with new onset type 1 diabetes, 34 (8%) had elevated anti-tTG antibodies: CD was diagnosed in 14, anti-tTG normalisation occurred in 13 and duodenal biopsies did not suggest CD in seven without anti-tTG antibody normalisation. Protective factors for a subsequent CD diagnosis were older age (p = 0.009) and mildly elevated anti-tTG antibody levels at the time of the type 1 diabetes diagnosis (p = 0.007), and decreased anti-tTG levels within six months of diagnosis (p = 0.03).
CONCLUSION: Serological follow-up of a diet containing gluten is recommended for children who have newly diagnosed type 1 diabetes and slightly elevated anti-tTG antibodies with no symptoms that suggest CD.
