Abstract
Clinical response is typically observed in most adults with celiac disease (CD) after treatment with a gluten-free diet (GFD). The rate of mucosal recovery is less certain. The aims of this study were (1) to estimate the rate of mucosal recovery after GFD in a cohort of adults with CD, and (2) to assess the clinical implications of persistent mucosal damage after GFD. The study group included adults with biopsy-proven CD evaluated at the Mayo Clinic who had duodenal biopsies at diagnosis and at least one follow-up intestinal biopsy to assess mucosal recovery after starting a GFD. The primary outcomes of interest were mucosal recovery and all-cause mortality. Of 381 adults with biopsy-proven CD, 241 (73% women) had both a diagnostic and follow-up biopsy available for re-review. Among these 241, the Kaplan–Meier rate of confirmed mucosal recovery at 2 years following diagnosis was 34% (95% confidence interval (CI): 27–40%), and at 5 years was 66% (95% CI: 58–74%). Most patients (82%) had some clinical response to GFD, but it was not a reliable marker of mucosal recovery ( P =0.7). Serological response was associated with confirmed mucosal recovery ( P =0.01). Poor compliance to GFD ( P <0.01), severe CD defined by diarrhea and weight loss ( P <0.001), and total villous atrophy at diagnosis ( P <0.001) were strongly associated with persistent mucosal damage. There was a trend toward an association between achievement of mucosal recovery and a reduced rate of all-cause mortality (hazard ratio=0.13, 95% CI: 0.02–1.06, P =0.06), adjusted for gender and age. Mucosal recovery was absent in a substantial portion of adults with CD after treatment with a GFD. There was a borderline significant association between confirmed mucosal recovery (vs. persistent damage) and reduced mortality independent of age and gender. Systematic follow-up with intestinal biopsies may be advisable in patients diagnosed with CD as adults.This publication has 64 references indexed in Scilit:
