From the time of Gee's landmark writings, the recent history of celiac disease (CD) can be divided into many ages, each driven by a diagnostic advance and a deeper knowledge of disease pathogenesis. At the same time, these advances were paralleled by the identification of new clinical patterns associated with CD and by a continuous redefinition of the prevalence of the disease in population. In the beginning, CD was considered a chronic indigestion, even if the causative food was not known; later, the disease was proven to depend on an intolerance to wheat gliadin, leading to typical mucosal changes in the gut and to a malabsorption syndrome. This knowledge led to curing the disease with a gluten-free diet. After the identification of antibodies to gluten (AGA) in the serum of patients and the identification of gluten-specific lymphocytes in the mucosa, CD was described as an immune disorder, resembling a chronic "gluten infection". The use of serological testing for AGA allowed identification of the higher prevalence of this disorder, revealing atypical patterns of presentation. More recently, the characterization of autoantibodies to endomysium and to transglutaminase shifted the attention to a complex autoimmune pathogenesis and to the increased risk of developing autoimmune disorders in untreated CD. New diagnostic assays, based on molecular technologies, will introduce new changes, with the promise of better defining the spectrum of gluten reactivity and the real burden of gluten related-disorders in the population. Herein, we describe the different periods of CD experience, and further developments for the next celiac age will be proposed. 展开更多

Celiac disease(CD) is a type of intestinal malabsorption syndrome,in which the patients are intolerant to the gliadin in dietary gluten,resulting in chronic diarrhea and secondary malnutrition. The disease is common in Europe and the United States,but only sporadic reports are found in East Asia including China. Is CD really rare in China? We examined 62 patients by capsule endoscopy for chronic diarrhea from June 2003 to March 2008. Four patients with chronic diarrhea and weight loss were diagnosed to have CD. Under the capsule endoscopy,we observed that the villi of the proximal small bowel became short,and that the mucous membrane became atrophied in these four patients. Duodenal biopsies were performed during gastroscopy and the pathological changes of mucosa were confirmed to be Marsh 3 stage of CD. A gluten free diet significantly improved the conditions of the four patients. We suspect that in China,especially in the northern area where wheat is the main food,CD might not be uncommon,and its under-diagnosis could be caused by its clinical manifestations that could be easily covered by the symptoms from other clinical situations,particularly when it came to subclinical patients without obvious symptom or to patients with ex-traintestinal symptoms as the initial manifestations. 展开更多
