Prevalence of celiac disease in patients with juvenile chronic arthritis
ABSTRACT We estimated the prevalence of celiac disease in children with juvenile chronic arthritis (JCA), using antiendomysium antibodies as the screening test to select patients for intestinal biopsy. We studied 119 children with JCA and found four patients with antiendomysium antibodies. In three of these patients (2.5%), intestinal biopsy revealed villous atrophy; in the fourth the intestinal mucosa was normal. We conclude that the prevalence of celiac disease is increased in patients with JCA.

ABSTRACT: Celiac disease (CD) is frequently accompanied by a variety of extradigestive manifestations, thus making it a systemic disease rather than a disease limited to the gastrointestinal tract. This is primarily explained by the fact that CD belongs to the group of autoimmune diseases. The only one with a known etiology is related to a permanent intolerance to gluten. Remarkable breakthroughs have been achieved in the last decades, due to a greater interest in the diagnosis of atypical and asymptomatic patients, which are more frequent in adults. The known presence of several associated diseases provides guidance in the search of oligosymptomatic cases as well as studies performed in relatives of patients with CD. The causes for the onset and manifestation of associated diseases are diverse; some share a similar genetic base, like type 1 diabetes mellitus (T1D); others share pathogenic mechanisms, and yet, others are of unknown nature. General practitioners and other specialists must remember that CD may debut with extraintestinal manifestations, and associated illnesses may appear both at the time of diagnosis and throughout the evolution of the disease. The implementation of a gluten-free diet (GFD) improves the overall clinical course and influences the evolution of the associated diseases. In some cases, such as iron deficiency anemia, the GFD contributes to its disappearance. In other disorders, like T1D, this allows a better control of the disease. In several other complications and/or associated diseases, an adequate adherence to a GFD may slow down their evolution, especially if implemented during an early stage.07/2013; 2013:127589.

ABSTRACT: The prevalence of coeliac disease (CD) in systemic lupus erythematosus (SLE) is unclear since evidence of this co -association is scarce. Furthermore, CD -specific antibodies have been described in patients with SLE without biopsy -confirmed CD. Here we describe the diagnostic challenges of CD in a patient suffering from SLE and secondary antiphospholipid syndrome, with transient positive serum levels of CD -specific antibodies, with an increased genetic risk for CD, demonstrated by HLA-DQ2 positivity. Guidance is still needed for the CD diagnosis in some atypical conditions

ABSTRACT: Background & Aims: The relationship between celiac disease and many autoimmune disorders has been explained by the sharing of a common genetic factor. In a multicenter national study, we examined the relationship between the prevalence of autoimmune disorders in celiac disease and the duration of exposure to gluten. Methods: Over a 6-month period, 909 patients with celiac disease (group A; mean age, 16.1 ± 3.8 years; grouped according to age at diagnosis into three subgroups [group A1, 10 years]), 1268 healthy controls (group B; mean age, 20.8 ± 4.5 years), and 163 patients with Crohn's disease (group C; mean age, 28.8 ± 10 years) were evaluated for the presence of autoimmune disorders. Results: Prevalence of autoimmune disorders in group A was significantly higher than in group B (14% vs. 2.8%; P < 0.000001) but not higher than in group C (12.9%). Prevalence of autoimmune disorders in celiac disease increased with increasing age at diagnosis: 5.1% in group A1, 17% in group A2, and 23.6% in group A3 (P = 0.000001). In group A3, the prevalence of autoimmune disorders was significantly higher than in group C. In a logistic regression model, age at diagnosis was the only significant predictor variable of the odds of developing an autoimmune disorder (r = 0.3; P < 0.000001). Conclusions: Our data show for the first time that the prevalence of autoimmune disorders in celiac disease is related to the duration of exposure to gluten.Gastroenterology 08/1999; 117(2):297-303.
