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.
"The association between coeliac disease (CD) and a wide spectrum of autoimmune diseases (AID) such as type 1 diabetes mellitus  , autoimmune thyroid disease , juvenile idiopathic arthritis  or autoimmune liver disease  has been well documented in the medical literature before. The appearance of CD -specific antibodies has also been described in patients with other AID, like systemic lupus erythematosus (SLE), with much lower prevalence and controversial clinical relevance, since not all of them were diagnosed as coeliac following intestinal biopsy   "
[Show abstract][Hide abstract] 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
"Other associated ADs, such as CD, have been previously described in patients with JIA, with a prevalence rate of 2.5% to 7% [9, 171, 172]. Moreover, a significantly increased cases of JIA in first-grade relatives of celiac patients have been found . "
[Show abstract][Hide abstract] 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.
"Malnourishment is also more common in children with inflammation of the maxillo-mandibular joint, and in children in whom the digestive tract is affected to the point that nutrient assimilation is reduced. Coeliac disease, for example, is about seven times more common in children with JIA than in the general population . Many of the drugs used in treating the disease can also cause disturbances of the gastro-intestinal tract. "
[Show abstract][Hide abstract] ABSTRACT: Juvenile idiopathic arthritis (JIA) is the most common joint disorder in developing children. Juvenile idiopathic arthritis is difficult to diagnose and treat. In some patients, signs and symptoms can be frustratingly inconsistent, contradictory or idiosyncratic. Short stature in patients with JIA is usually due to reduced growth in the lower extremities, and only rarely due to reduced growth in the spinal column. In some studies, children with JIA were found to have infantile body proportions. Puberty is delayed in children with JIA. In children with chronic arthritic disorders, there is a strong correlation between the activity of the disease and the age of puberty. The main goals in reducing growth retardation in children with JIA are promoting timely remission and reducing the duration and dosage of corticosteroid treatment. It is important to regularly monitor physical development. Further improvements to the treatment protocol depend on continued interdisciplinary research involving paediatricians, rheumatologists and clinical anthropologists.
