“To biopsy or not to biopsy” –that is the question (for Celiac disease)

First off -thanks to Ben Gold for the following reference and the blog title as well.

  • CM Trovato et al. Am J Gastroenterol 2015; 110: 1485-89.

In this retrospective study (alluded to in a previous post:Celiac Update September 2015 | gutsandgrowth), the researchers examined whether “biopsy-sparing” protocols for symptomatic children with high titers of serum anti-transglutaminase (anti-TTG) antibody levels (>10 times upper limit of normal [ULN]) would be suitable for asymptomatic patients.

Background: In 2012, the European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) published guidelines that it is possible to omit endoscopic biopsies for celiac disease if patients older than 2 years of age had high anti-TTG titers (>10 times ULN), positivity for EMA, compatible HLA DQ2 or HLA DQ8 and were symptomatic.

Findings:

  • Among 196 patients, the 40 who were asymptomatic had severe Marsh lesions (3a, 3b, or 3c) in 92% compared with 91% of 156 who were symptomatic. In both groups, the remaining patients had either Marsh 1 or 2 lesions.
  • 94.4% of patients had improved serology during followup along with symptomatic improvement (in those with symptoms)

Bottomline:  Whether symptomatic or not, those with high antiTTG titers who meet all of the other ESPGHAN criteria have a very high probability of celiac disease.

Briefly noted: K Marild et al. Am J Gastroenterol 2015; 110: 1475-84. This study, based on a large prospective Norwegian cohort (72,921 children) that frequent infections (>10) in the first 18 months of life increased the risk of celiac disease with an adjusted odds ratio of 1.32 (highest infection quartile compared to lowest infection quartile).  However, alternative explanations, including surveillance bias and reverse causation, cannot be excluded.
