Abstract

BACKGROUND:

Celiac disease is a multiform, challenging condition characterized by extremely variable features. Our goal was to define clinical, serological and histopathological findings in a large cohort of celiacs diagnosed in a single referral center.

METHODS:

From January 1998 to December 2012, 770 patients (599 females, median age 36 years, range 18-78 years) were diagnosed as celiacs at St. Orsola-Malpighi Hospital (Bologna, Italy). The clinical phenotypes were classified as: 1) classical (malabsorption syndrome); 2) non-classical (extraintestinal and/or gastrointestinal symptoms other than diarrhea); 3) subclinical. Serology, duodenal histology, comorbidities, response to gluten-free diet and complications were evaluated.

RESULTS:

Disease onset was symptomatic in 610 patients (79%), while 160 celiacs showed a subclinical phenotype. In the symptomatic group the non-classical prevailed over the classical phenotype (66% vs 34%). Diarrhea was found in 27%, while other gastrointestinal manifestations were bloating (20%), aphthous stomatitis (18%), alternating bowel habit (15%), constipation (13%) and gastroesophageal reflux disease (12%). Extraintestinal manifestations included osteopenia/osteoporosis (52%), anemia (34%), cryptogenic hypertransaminasemia (29%) and recurrent miscarriages (12%). Positivity for IgA tissue transglutaminase antibodies was detected in 97%. Villous atrophy was found in 87%, while 13% had minor lesions consistent with potential celiac disease. A large proportion of patients showed autoimmune disorders, i.e. autoimmune thyroiditis (26.3%), dermatitis herpetiformis (4%) and diabetes mellitus type 1 (3%). Complicated celiac disease was very rare.

CONCLUSIONS:

Our study demonstrates that the clinical profile of celiac disease changed over time with an increasing rate of non-classical and subclinical phenotypes.
