Abstract
The clinical presentation of celiac disease in children is very variable and differs with age. The prevalence of atypical presentations of celiac disease has increased over the past 2 decades. Several studies in adults and children with celiac disease indicate that obesity/overweight at disease onset is not unusual. In addition, there is a trend towards the development of overweight/obesity in celiac patients who strictly comply with a gluten-free diet. However, the pathogenesis and clinical implications of the coexistence of classic malabsorption (e.g., celiac disease) and overweight/obesity remain unclear. This review investigated the causes and main clinical factors associated with overweight/obesity at the diagnosis of celiac disease and clarified whether gluten withdrawal affects the current trends of the nutritional status of celiac disease patients.

Abstract
Objectives. The aim of this study is to investigate the effects of coeliac disease on cardiac function in children using conventional transthoracic echocardiography (TTE) and tissue Doppler echocardiography (TDE). Methods. Coeliac disease patients were evaluated in two different groups based on serum endomysial antibody (EmA) titers (EmA (+) and EmA (−)), and the data obtained by conventional and TDE studies were compared between the patient groups and healthy controls. Results. There was no significant difference between EmA (+) and EmA (−) groups in terms of the conventional TTE parameters, including ejection fraction (EF), fractional shortening (FS), and left ventricle end diastolic diameter (LVEDD), that show the left ventricular systolic function (P = 0.727, P = 0.317, P = 0.118). TDE showed a significant difference in left ventricle (LV) isovolumic relaxation time (LV IVRT) and LV myocardial performance index (LV MPI) parameters between EmA (+) and EmA (−) patient groups (P < 0.0001). Conclusion. The measurement of LV MPI and LV IVRT parameters by TDE would be beneficial in early determination of the cardiac involvement and establishing appropriate treatment and followup of patients with coeliac disease as well as in making distinction between EmA (+) and EmA (−) patients.

Abstract
The mode of presentation of patients with celiac disease has changed dramatically over the recent decades, with diarrheal or classic presentations becoming less common. This trend is most markedly seen in children, whose main presentations include recurrent abdominal pain, growth issues, and screening groups at risk. Among adults, presentations include diarrhea, anemia, osteoporosis, and recognition at endoscopy performed for gastroesophageal reflux disease, as well as screening. The groups most commonly screened include family members of patients with celiac disease, Down syndrome, and autoimmune diseases.

Abstract
OBJECTIVES In the present study, we aimed to assess bone status and the effect of gluten-free diet (GFD) in children with celiac disease (CD), and to evaluate the predictive value of standard serum biochemical indices in the diagnosis of bone mineral density (BMD) disturbances. METHODS Forty-five children at the time of diagnosis of CD (group A, 77.8% girls) and 36 children receiving GFD for >2 years (group B, 75% girls) were included. Sixteen children in group A were reexamined 12 months after initiation of GFD. Serum measurements of biochemical bone health indices and BMD, assessed by dual x-ray absorptiometry, were obtained. RESULTS Patients after 1 year of receiving GFD had higher BMD z scores compared with baseline (-1.45 ± 0.28 vs -0.61 ± 0.25, respectively, P = 0.004). BMD z scores were significantly lower than expected for the normal population, after 1 (P = 0.03) or at least 2 (P < 0.001) years of receiving GFD. In group B, BMD z score was positively correlated with 25-hydroxy vitamin D levels (P = 0.009). In the repeated measurements group, 25-hydroxy vitamin D differed between pre- and post-GFD (P = 0.018). No biochemical index was capable of predicting an abnormal BMD z score (receiver operating characteristic curve analysis, all of the areas under the curve <0.66). CONCLUSIONS GFD has a beneficial effect on bone health. Two years receiving diet do not ensure normalization. Biochemical markers are not indicative of BMD disturbances. Dual x-ray absorptiometry should be included in the standard management of children with CD.

Abstract
Evidence of the prevalence of celiac disease comes from serological screening studies. These have revealed that celiac disease is common, occurring in about 1 % of the population worldwide. There are some countries with higher prevalence rates such as Finland and others with lower rates, for example Germany. The disease is found in most continents and appears to be increasing. Most people with the disease are not currently diagnosed though women are diagnosed more frequently than men. The mode of presentation has changed both in children and adults with diarrhea and a malabsorption syndrome becoming less common. Abdominal pain and growth issues are major modes of presentation in children, while anemia, osteoporosis, and recognition at endoscopy performed for GERD are seen as modes of presentation in adults. Screening of at risk groups is a major mode of presentation for both adults and children.

Abstract
OBJECTIVES The diagnosis of celiac disease (CD) is based on the histological identification of gluten-sensitive enteropathy and detection of anti-tissue transglutaminase antibodies (tTGA) and/or endomysial antibodies. Serial measurements of tTGA are now recommended as a follow-up strategy to monitor compliance with a gluten-free diet (GFD). We evaluated the performances of a quantitative radiobinding assay (RBA) of tTGA immunoglobulin A at diagnosis and during monitoring of GFD in pediatric CD. METHODS Eighty children with confirmed CD were selected. Levels of serum tTGA measured by RBA and a commercial enzyme-linked immunosorbent assay (ELISA) were compared at diagnosis. The relation between RBA-tTGA levels and histological damage was analyzed, as well as the time course of tTGA clearance during GFD. RESULTS Both RBA and ELISA showed high sensitivity and specificity for tTGA detection at diagnosis. There was no relation between RBA-tTGA levels at diagnosis and severity of mucosal damage. Upon initiation of GFD, the rate of RBA-tTGA positivity declined slower than that of endomysial antibodies positivity, with >50% of the children still tTGA positive at year 5; however, tTGA levels decreased rapidly during the first year of GFD and more slowly thereafter. Children who seroreverted had lower tTGA levels at diagnosis (2080±1554 cpm) than those who remained tTGA positive throughout follow-up (3688±1435 cpm). CONCLUSIONS The high sensitivity of RBA is likely responsible for higher tTGA positivity rates during GFD than previously reported with ELISA. A decreasing trend for tTGA levels may represent a better surrogate marker of compliance with GFD than absolute normal tTGA levels.

Abstract
Celiac disease (CD) is an autoimmune disorder occurring in genetically susceptible subjects. The incidence of CD is around 1%, and it is much more common in first-degree relatives of CD patients, 10%-18%. However, the pattern of the genetic inheritance is still obscure. Environmental factors are undoubtedly affecting the disease's clinical presentation, time at presentation, and may have an effect on the characteristics of the disease. The clinical presentation of CD has shifted during the previous decades from the classical presentation in which the toddler suffers from diarrhea, constipation, vomiting, failure to thrive, abdominal distension, etc., to the child with a monosymptomatic presentation, such as anemia, as well as an enlarged list of extra-intestinal disorders. The diagnosis of CD is being established by symptoms consistent with CD and positive serology. The ultimate diagnosis should be made upon histological evaluation of the small bowel mucosa. The treatment of CD is a lifelong, strict gluten-free diet (GFD). Compliance with a GFD is quite difficult. Therefore, new strategies for prevention and treatment modalities other than GFD are greatly needed. Recently several promising therapeutic modalities have been developed; these include resuming traditional baking techniques. Another methodology is using probiotic-driven prolylendopeptidase. Another pathway to tackle the therapeutic option in CD is by down-regulation of the activity of zonulin-the active pump enabling gluten to enter the enterocytes. We are facing an era where other modalities beyond a GFD might allow CD patients to be able to tolerate occasionally a small amount of gluten in their diet.

Abstract
OBJECTIVE The high prevalence of celiac disease (CD) prompted us to evaluate a new, noninvasive disease screening strategy. The aim was to identify CD in 6- to 8-year-old children for a timely diagnosis, start gluten-free diet (GFD) in compliant subjects, achieve the growth target, and prevent CD complications. METHODS Five thousand subjects were invited to participate in the study. Four thousand forty-eight saliva samples were tested for anti-tissue transglutaminase (tTG) immunoglobulin (Ig)A using a fluid-phase radioimmunoprecipitation method. Positive children were tested for serum radioimmunoassay tTG IgA, enzyme-linked immunosorbent assay tTG IgA, and anti-endomysium IgA. Children confirmed as positive by serum assays underwent endoscopy with duodenal biopsies and, at the diagnosis of CD, were suggested to start GFD. RESULTS Consent was obtained from 4242 parents (84.8%) for the screening to be performed, and adequate saliva samples were collected from 4048 children (95.4%). Thirty-two children were found to be salivary tTG IgA positive and 9 with borderline autoantibody levels. Thirty-one of the 32 and 3 of the 9 subjects were also serum positive. Twenty-eight children showed villous atrophy when undergoing intestinal biopsy, whereas 1 had Marsh 1 lesions; 3 children were suggested to start GFD without performing endoscopy. CD prevalence in the population investigated (including 19 CD known cases) was 1.16%. The ratio between screening-detected patients and those diagnosed before the screening was 3:2. The ratio between symptomatic and asymptomatic patients was 1:1.6. CONCLUSIONS We demonstrated that it is possible to perform a powerful, simple, well-accepted, and sensitive CD screening using saliva. Until now, the compliance with GFD in children with CD has been optimal.

Abstract
Esta comunicação apresenta o cenário da doença celíaca e suas implicações em hábitos, práticas alimentares e qualidade de vida de indivíduos intolerantes ao glúten. Apresenta dados importantes sobre a questão que, mundialmente, é considerada problema de saúde pública. Por ser uma doença cujo tratamento é fundamentalmente dietético, a terapia durante a transição alimentar deve ser bem conduzida pelo nutricionista para melhor adesão do paciente à dieta, considerando que a inclusão de novas práticas alimentares pode significar uma ruptura com a identidade individual e cultural: a alimentação de cada cidadão não pode ser deslocada da sociedade. Nesse contexto, a melhoria da qualidade de vida passa a ser um dos resultados esperados tanto das práticas assistenciais quanto das políticas públicas para o setor nos campos da promoção da saúde e da prevenção de doenças. A vigilância sanitária contempla as ações capazes de eliminar, diminuir ou prevenir riscos à saúde e de intervir nos problemas sanitários decorrentes do meio ambiente, da produção e circulação de bens e da prestação de serviços de interesse da saúde. O conhecimento do cenário da doença celíaca no País se justifica pela necessidade de fundamentar as ações da política de alimentação e nutrição ancoradas no conceito de alimentação saudável com ênfase na dieta isenta de glúten. Os artigos pesquisados foram selecionados nas bases de dados MedLine e SciELO, considerando o período de 1995 a 2006.

Abstract
BACKGROUND Celiac disease is a common problem affecting children and adults, for which early diagnosis and treatment prevent complications and deaths. Seroprevalence studies in our environment are still scarce. AIMS To determine the seroprevalence of celiac disease by using human tissue antiendomysial and anti-transglutaminase antibodies, among children and adolescents who were attended at a general pediatric outpatient clinic. METHODS This was a seroprevalence study of descriptive cross-sectional design. First, assays for guinea pig tissue anti-transglutaminase antibodies were performed. Subsequently, in the positive cases, assays for human tissue antiendomysial and anti-transglutaminase antibodies were performed. RESULTS The seroprevalence of celiac disease by means of anti-guinea pig tissue anti-transglutaminase antibodies was 5% (42/831; 95% CI: 3.76%-6.90%). Considering three positive tests, the seroprevalence was 1.9% (16/831; 95% CI: 1.83%-1.97%). The concordance of human anti-transglutaminase with antiendomysial was 71%. CONCLUSIONS The seroprevalence of celiac disease was high. Serological screening for celiac disease among children and adolescents who present signs and/or symptoms compatible with celiac disease should be performed routinely, as well as in groups already known to be at risk, given the high seroprevalence of celiac disease observed in our environment.

Abstract
OBJECTIVES Celiac disease is an autoimmune enteropathy caused by gluten ingestion in genetically susceptible individuals. Anti-transglutaminase autoantibody (tTGAb) assay is useful to detect candidates undergoing intestinal biopsy. Our aim was to investigate whether the DQB1*02 allele could influence tTGAb titers and the clinicopathological expressivity of the disease. METHODS A total of 124 patients with celiac disease, tested for RIA tTGAb at diagnosis, were typed for HLA-DRB1, -DQA1, and -DQB1 genes and divided according to the number of DQB1*02 alleles: group 1, homozygous; group 2, heterozygous; group 3, negative. RESULTS The mean of tTGAb indexes was significantly higher in group 1 patients than in group 2 (P < 0.02) and group 3 patients (P < 0.01). Patients with at least 1 DQB1*02 allele showed more often a typical CD and diffuse histological lesions than did patients in the other groups. CONCLUSIONS The study demonstrates that tTGAb titers are HLA-DQB1*02 dose dependent, with significantly higher levels in homozygous individuals. Moreover, individuals with at least 1 HLA-DQB1*02 allele tend to have a more expressed clinical and histological form of celiac disease.

Abstract
BACKGROUND Serum radioimmunoassay (RIA) tissue transglutaminase autoantibodies (tTG-Abs) proved to be a sensitive test also during coeliac disease (CD) follow-up. We demonstrated that RIA tTG-Abs could be detected in human saliva. AIM To evaluate salivary RIA tTG-Abs in coeliac children on gluten-free diet (GFD). METHODS Saliva and serum samples from 109 coeliac children were evaluated at diagnosis (group 1: 71 females, median age 9.4 years) and 58 of them on GFD: 36 after 3-6 months (group 2a), 34 at 9 months or more (group 2b). Two gender- and age-matched control groups: 89 gastroenterological patients (group 3) and 49 healthy subjects (group 4) participated in the study. Saliva and serum tTG-Abs were detected by RIA and compared with serum tTG-Abs ELISA and IgA anti-endomysium antibodies (EMA). RESULTS Salivary RIA tTG-Abs were found in 94.5%, 66.7% and 50.0% of groups 1, 2a and 2b CD patients and in 98.2%, 72.2% and 50.0% of corresponding serum samples, respectively. tTG-Abs decreased with GFD progression and a correlation was found between saliva and serum titres (r = 0.75, P = 0.0001). During the CD follow-up, salivary and serum RIA sensitivities were comparable, and higher with respect to EMA and ELISA. CONCLUSIONS This study demonstrates that it is possible to detect salivary tTG-Abs with high sensitivity not only at CD diagnosis, but also during GFD.

Abstract
Celiac disease is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible individuals. Many reports mention the association between epilepsy and celiac disease and the occasional presence of occipital corticosubcortical calcifications. We investigated 255 children with idiopathic epilepsy. Evaluation included use of routine, easily obtainable studies. Patients were screened for immunoglobulin A (IgA), immunoglobulin G (IgG) antigliadin antibodies and immunoglobulin A antitissue transglutaminase antibodies. Moreover, presence of IgA antiendomysial and antireticulin antibodies was screened. Patients with positive IgA antigliadin antibodies underwent a small intestinal biopsy. Controls consisted of 280 healthy children. Intestinal histopathologic changes, positive IgA antigliadin antibodies or IgG antigliadin antibodies, antireticulin antibodies, and antitissue transglutaminase IgA antibodies were found in five epileptic children but not in control subjects (P = 0.0241). Intracranial calcifications were not found in epileptic children with celiac disease. The findings indicate that prevalence of silent celiac disease is increased among children with idiopathic epilepsy; the type of epilepsy does not appear to play a role. Serum antitissue transglutaminase IgA antibodies could be a good marker for celiac disease screening. Occipital corticosubcortical calcifications are rarer in children with celiac disease and epilepsy.

Abstract
Undiagnosed and untreated celiac disease (CD) constitutes an increasing skeletal health problem due to its association with low bone density and fractures. Examinations of skeletal status in children using dual-energy X-ray absorptiometry (DXA) are prone to size-related misinterpretation. In contrary, the analysis of muscle-bone relationship seems to limit a possibility of misdiagnosis because skeletal status is evaluated from the functional perspective. The study was aimed to assess skeletal status of children suffering from CD with the use of muscle-bone functional algorithm. The study group comprised 29 celiac patients (13.7yr+/-2.9) on gluten-free diet (GFD), and 24 newly diagnosed atypical celiac patients, including subgroup with normal height (n=14; 12.6yr+/-3.9) and subgroup with short stature (n=10; 12.2yr+/-2.9). Muscular and skeletal status was evaluated by DXA (DPX-L, GE). Anthropometry, total body bone mineral density (TBBMD, g/cm(2)). and total body bone mineral content (TBBMC, g) as well as lean body mass (LBM, g) were evaluated. Muscle-bone interactions were estimated using TBBMC/LBM ratio. Previously established references for healthy controls were used for the calculation of Z-scores (age-matched) and SD-scores (height-matched). GFD treated celiacs and atypical celiacs with normal body height had TBBMD, TBBMC, LBM, and TBBMC/LBM ratio Z-scores and SD-scores within normal range for healthy controls. In contrary, atypical celiacs with short stature had significantly lower Z-scores for TBBMD (-2.3+/-0.4), TBBMC (-2.1+/-0.3), LBM (-1.4+/-0.3). and TBBMC/LBM ratio (-2.3+/-0.6) when compared to respective values observed in GFD treated celiacs (p<0.001, p<0.001, p<0.05, p<0.01) and atypical celiacs with normal height (p<0.01, p<0.01, p<0.05, p<0.01). When body-height matching of DXA data was used to limit the influence of body size, the atypical celiacs with short stature had SD-scores for TBBMD (-1.3+/-0.7), TBBMC (-1.3+/-0.6), and LBM (+0.8+/-0.3) not significantly different from the corresponding SD-scores obtained in the remaining 2 groups. Nevertheless, short stature in atypical celiacs still coincided with significantly lower TBBMC/LBM ratio SD-score of -1.9+/-0.7 when compared to values observed in GFD treated celiacs (+0.04+/-0.2; p<0.05) and atypical celiacs with normal height (-0.4+/-0.2; p<0.05). GFD regime in classic celiacs corresponded with physiological values of DXA assessed indicators of bone and muscle status as well as normal muscle-bone interactions. Untreated atypical celiacs may present a broad spectrum of heterogeneous abnormalities from normal to markedly depressed TBBMC/LBM ratio values pointing on the marked imbalance between TBBMC and LBM.

Abstract
Celiac disease (CD) is an underdiagnosed disease occurring in different clinical forms. This study aimed to determine the prevalence of CD among blood donors from Ribeirão Preto, Brazil, and to study some demographic characteristics of celiac patients. Blood samples from 3000 blood donors were tested for the presence of tissue transglutaminase antibody and positive samples were tested for endomysial antibody. Donors positive to both tests were referred for clinical evaluation and for a jejunal biopsy. Twenty-four samples were moderately/strongly positive for transglutaminase, with 9 of them being endomysial negative and 15 positive. Of the 13 biopsies obtained from 12 females and 1 male, 1 was classified as Marsh grade IV, 4 as grade III, 2 as grade II, 4 as grade I, and 2 as grade 0. Estimated prevalence was therefore 1:273 (0.33%; 95% CI, 0.127 to 0.539). The 1:273 estimated prevalence of CD detected indicates that the disease is not rare in Brazil. The frequency was higher among females and among individuals of European descent, with a significantly higher frequency for a family history of digestive tract cancer or epilepsy.

Abstract
We report a case of macroamylasemia in an 11-year-old boy. We compare our clinical and paraclinical data with those described in pediatric literature. Macroamylase resulted in a complex of amylase and immuglobulin. Its fortuitous detection did not reveal, up to now, any associated pathology, in particular any autoimmune disorders or celiac disease. Identification of this biochemical abnormality is essential in order to avoid invasive investigations and/or unnecessary therapies.

Abstract
Celiac disease is a complex autoimmune enteropathy that affects the small bowel in genetically predisposed individuals. It is thought that celiac disease is the result of an inappropriate T cell-mediated immune response against ingested gluten protein. The characteristic lesion of the small intestinal mucosa includes loss of absorptive villi and infiltration of the lamina propria with inflammatory cells. The clinical presentation of celiac disease varies greatly depending on patient's age, duration and extent of the disease, and the presence of extraintestinal manifestations. Unfortunately, most patients with celiac disease have either silent or atypical presentations, thus escaping diagnosis for several years. Medical nutrition therapy with lifelong adherence to a strict gluten-free diet is the only accepted treatment of celiac disease. Individuals at risk for this entity should undergo appropriate serologic testing, but there is no evidence to support mass screening.

Abstract
BACKGROUND The aim of this study is to assess the prevalence of unrecognized adult celiac disease in Central Anatolia of Turkey and establish if prevalence figures are similar to other reports in the international literature. METHODS Subjects were randomly selected from patients at the time of blood sampling because of a routine examination or suspicion of some disorder other than celiac diseases and were screened with anti-tissue transglutaminase IgA and serum IgA measurements. Duodenal biopsies were taken from the patients who were found positive for anti-tissue transglutaminase IgA and had low IgA levels. RESULTS A total of 906 subjects between 20 and 59 years of age were included. Small bowel biopsies were performed for 55 of the 906 participants. Fifty-two of 55 participants taken biopsies had anti-tissue transglutaminase IgA levels greater than 15 IU/mL and 3 of them had low IgA levels. Celiac disease was diagnosed as 9 of 906 (0.99%). The majority of the patients with celiac disease had nonspecific gastrointestinal symptoms. There was no correlation between the titers of anti-tissue transglutaminase IgA and the severity of histopathologic findings. CONCLUSIONS In this study, we found that unrecognized adult celiac disease in Central Anatolia affects approximately 1% of the population, and the major constellation of symptoms are nonspecific gastrointestinal related. Serologic data are not adequate for a definite diagnosis, but the anti-tissue transglutaminase IgA test has high diagnostic value and may be used as screening tool. Confirmation with intestinal biopsy is required for a definite diagnosis.

Abstract
AIM Iron deficiency anaemia is a frequent finding seen in coeliac disease, which can be diagnosed alone or with other findings. In this study, our aim was to determine the prevalence of coeliac disease in children with iron deficiency anaemia without significant gastrointestinal symptoms. METHODS There were 135 children with iron deficiency anaemia in the patient group (group 1), and 223 healthy children without iron deficiency anaemia in the control group (group 2) in this study. Antiendomysial antibody (EMA) IgA test was given to both groups. Antiendomysial antibody-positive patients underwent small intestine biopsy. RESULTS The mean age was 7.2+/-4.6 (2-16) y in the patient group (group 1) and 8.2+/-3.8 (2-16) y in the control group (group 2), and no significant difference between the two groups was detected. In terms of gender, there was a significant difference between groups 1 and 2 (M/F: 74/61 and 98/125, respectively) ( p<0.05). EMA was positive in six cases in group 1 (4.4%), and villous atrophy and/or inflammation in the lamina propria with increased intraepithelial lymphocytes was seen on small intestine biopsy in these patients. In the control group, EMA was negative in all children. In detailed histories of patients with coeliac disease diagnosis, recurrent iron deficiency anaemia/pica was found in four patients (66.7%) and occasionally foul-smelling or watery stool attacks were seen in four patients (66.7%). Three of these six patients (50%) had short stature. CONCLUSION The prevalence of coeliac disease was high in patients with iron deficiency anaemia; therefore, gastrointestinal findings should be further examined for coeliac disease, and the possibility of coeliac disease should be investigated in patients with recurrent iron deficiency anaemia and short stature.

Abstract
INTRODUCTION Understanding of celiac disease has changed with the advent of serological markers (antigliadin IgA, anti-endomysial IgA and anti-transglutaminase IgA antibodies) and with the identification of major susceptibility genes (HLA-DQA1*05-DQB1*02). Reports of the efficacy of these diagnostic tests have varied, depending on the methodology used and the population investigated. OBJECTIVES To determine the clinical utility of genetic and serological markers in the diagnosis of celiac disease, their relationship with histological lesions and their changes during treatment, in order to establish an optimal diagnostic algorithm in our environment. PATIENTS AND METHODS We performed a retrospective study of 590 patients from the health area of Badajoz referred to the Immunology Laboratory for screening or follow-up of celiac disease. The results of intestinal histology, serological markers (antigliadin IgA, anti-endomysial IgA and anti-transglutaminase IgA antibodies), and genomic typing (HLA-DQA1*05-DQB1*02) were analyzed. RESULTS The sensitivity and specificity of serological tests were greater than 90 %, with a negative predictive value of 98-100 %. HLA-DQA1*05-DQB1*02 was detected in 97 % of celiac patients, with a very high negative predictive value (99 %). On biopsy, 95 % of the patients with some grade of intestinal lesion were positive for antigliadin and/or anti-endomysial antibodies. CONCLUSION To avoid missed diagnoses, the diagnostic algorithm of celiac disease should include at least two serological markers (antigliadin antibodies and anti-endomysial and/or anti-transglutaminase antibodies) and IgA quantification. Genomic typing should be carried out if one or more markers are positive or if the subject belongs to any of the risk groups. The physician should decide on the advisability of intestinal biopsy on the basis of the patient's clinical and immunological history.

Abstract
Childhood celiac disease (CD) is considered rare in the United States. Consequently there are few data concerning its clinical presentation. A validated questionnaire was distributed to families of children with CD. One hundred forty-one children with biopsy-proven CD were included in the study. We found significant differences in the clinical spectrum of children based on their infant feeding history. Exclusively breastfed children were significantly less likely to report failure to thrive (69% vs 88%, p<0.05) and short stature (37% vs 62%, p<0.05), and had a higher rate of "atypical'' symptoms (p<0.01). Breastfeeding alters the presentation and contributes to atypical presentations of CD and diagnostic delay. Pediatricians need to be aware of the diverse manifestations of celiac disease to reduce diagnostic delay.

Abstract
Gluten-sensitive enteropathy, otherwise known as celiac sprue, is characterized by an abnormal proximal small intestinal mucosa arising as a result of an inappropriate inflammatory response to ingested gluten antigens present in wheat in genetically susceptible individuals. This immune response is directed to a 33-mer peptide of the alpha gliadin component of gluten. The generation of an epitope for the recognition by CD4+ T cells requires deamination of the protein by tissue transglutaminase (tTG). Moreover, IgA anti tTG is highly sensitive and is specific serologic marker (95-99%) of celiac disease. They can be easily determined quantitatively, by ELISA of an accurate and relatively inexpensive technique. Therefore, tTG can be used as the first line diagnostic test in the work-up of celiac disease, as well as for screening purposes. Finally, tTG may contribute to future strategies in treating celiac disease either by producing nontoxic wheat or by generating oral vaccination that can prevent the disease.

Abstract
OBJECTIVE To test the possibility of detecting tissue transglutaminase autoantibodies (tTG-Abs) in saliva with a novel sensitive fluid-phase radioimmunoassay (RIA). STUDY DESIGN Paired saliva and serum samples from 39 patients with celiac disease (CD), at the first biopsy (Group 1: 28 females, mean age 11.5 +/- 11.1 years); 32 controls with a normal duodenal mucosa (Group 2: 18 females, mean age 8.1 +/- 3.6 years); and 32 healthy volunteers (Group 3: 21 females, mean age 31.7 +/- 9.8 years) were studied for tTG-Ab presence. Limit of positivity for salivary assay was calculated according to the 99th percentiles of Group 2 control children and was expressed as an autoantibody (Ab) index. RESULTS Salivary tTG-Abs were found in 97.4% of the patients with CD and in 100% of the corresponding serum samples. All Group 3 subjects were negative with both saliva and serum assays. A correlation between saliva and serum tTG-Ab titers was found (r=0.826, P=.0014). CONCLUSIONS This study demonstrates that it is possible to detect salivary tTG-Abs in CD with a non-invasive, simple to perform, reproducible and sensitive method.

Abstract
BACKGROUND Celiac disease is a multifactorial disorder of the proximal small intestine associated with a permanent intolerance to gluten. The HLA-DQ(alpha1*0501, beta1*02) heterodimer is strongly associated with this disease. MATERIALS AND METHODS The authors studied a sample of 354 unrelated Caucasoid individuals: 118 patients with celiac disease and 236 control subjects. All patients and controls subjects were born in Gran Canaria (Canary Islands) at least two generations ago. The authors typed the HLA-DQA1 and DQB1 genes by DNA methods. The positive and negative predictive values of the test were studied. RESULTS The mean age at diagnosis was 25.4 months, with a statistically significant proportion of females (64.4%, P < 0.002). For DQB1 gene, the susceptibility allele found was DQB1*02 (relative risk [RR] = 7.60, confidence interval [CI]: 5.35-10.78), whereas for the DQA1 gene, the susceptibility alleles found were DQA1*0501 (RR = 2.99, CI: 2.16-4.14) and DQA1*0201 (RR = 1.88, CI: 1.25-2.82). The presence of the DQ(alpha1*0501, beta1*02) heterodimer was strongly associated with the disease (92.4% in the patients group vs. 21.6% in control subjects). HLA-DQ8 heterodimer was absent in the authors' patients. DQB1*02 homozygous subjects presented a higher relative risk for celiac disease. There was no correlation of DQB1*02 dosage with age at onset below 12 years of age or with gender distribution. Sensitivity, specificity, and the positive and negative predictive values of the test were 92.4%, 78.4%, 68.1%, and 95.4%, respectively. CONCLUSIONS The presence of the DQ2 (DQA1*0501/DQB1*02) heterodimer is strongly associated with celiac disease in the population studied by the authors. The value of this test derives from its ability to exclude disease when a negative result occurs.

Abstract
In recent years, it has become evident that CD is much more common than previously appreciated, with a prevalence of 0.5% to 1% in Western, Arabian, and Indian populations. The disease may be present without symptoms (silent CD) or may present with extraintestinal manifestations only. Increasing awareness of the many faces of CD will increase diagnosis rate. CD patients have a cure for their disease, named the gluten-free diet, but this curative measure is very hard to adhere to. With the new insights into the pathogenesis of CD, clinicians enter an era where new treatment modalities for CD may turn into reality.

Abstract
Autism is a life-long developmental disorder affecting as many as 1 in 500 children. The causes for this profound disorder are largely unknown. Recent research has uncovered pathology in the gastrointestinal tract of autistic children. The pathology, reported to extend from the esophagus to the colon, is described here along with other studies pointing to a connection between diet and the severity of symptoms expressed in autism. The evidence that there is impaired intestinal permeability in autism is reviewed, and various theories are discussed by which a leaky gut could develop. Lastly, some possible ways in which impaired gastrointestinal function might influence brain function are discussed.

Abstract
BACKGROUND The prevalence of autoimmune disorders is increased in patients with celiac disease (CD), and it is unknown whether their first-degree relatives also have a high risk of autoimmune disorders. METHODS To assess the prevalence of autoimmune diseases in first-degree relatives of CD patients, the authors looked for autoimmune disorders in 225 first-degree relatives of 66 children with CD (group A) and in 232 first-degree relatives of 68 healthy children (group B). For both groups, serologic screening for CD was performed through antiendomysium (EMA) and tissue transglutaminase autoantibodies (tTGAA). EMA- and tTGAA-positive subjects were offered an intestinal biopsy. The age at onset of autoimmune diseases was also recorded in group A. RESULTS The prevalence of autoimmune disorders was significantly (P = 0.028) higher in group A (11 of 225, 4.8%) than in group B (2 of 232, 0.86%). In relatives of CD patients, the prevalence increased with age (chi2 for trend, 43.5; P < 0.0001). Serologic screening for CD was only positive in group A (15 of 225 subjects). An intestinal biopsy was performed in 13 of these 15 relatives (2 refused biopsy). Eleven of 13 had flat mucosa, with subclinical or silent forms of CD. The prevalence of autoimmune diseases in the EMA- and tTGAA-positive relatives of CD patients was significantly higher (3 of 15, 20%; P = 0.028; odds ratio, 6.3; 95% CI, 1/0.21-1/0.11, 4.9-7.6) than in those who were EMA and tTGAA negative (8/210, 3.8%). CONCLUSIONS The first-degree relatives of CD patients have an increased risk of autoimmune diseases, most likely connected with unrecognized subclinical or silent forms of CD.

Abstract
PURPOSE To heighten the awareness of primary care clinicians regarding the prevalence, clinical manifestations, diagnosis, and treatment of celiac disease (CD) in the primary care setting. DATA SOURCES Selected research, clinical guidelines, research and clinically based articles from current scientific literature, and current medical textbooks. CONCLUSIONS Celiac disease is commonly under diagnosed or misdiagnosed. Until recently, it was considered rare in the United States. New data indicate that 1:150 Americans are affected and demonstrate the protective effects of early diagnosis and treatment. IMPLICATIONS FOR PRACTICE Delays in the diagnosis and treatment of CD increase the risk of early mortality, associated autoimmune disease, neurologic complications, gastrointestinal malignancy, and fetal growth retardation, where pregnancy precedes diagnosis. Primary care clinicians must cultivate a high index of suspicion for CD in the primary care setting and bear it in mind as a differential diagnosis in many clinical situations.

Abstract
UNLABELLED To investigate whether factors in the fetal or neonatal period influence the risk of later development of coeliac disease we conducted a population-based register study. The Swedish Medical Birth Register was linked with the Hospital Discharge Register and identified 3392 singleton infants born in the period 1987-97 who developed coeliac disease. Perinatal data for these children were compared with all children born in these years. Exposure variables: Maternal age, parity and smoking habits in early pregnancy, preeclampsia, pregnancy duration and birthweight, birthweight by gestational week, Apgar score, neonatal icterus, neonatal infections, maternal-fetal blood group incompatibility, exchange transfusion, phototherapy. Odds ratios and test-based confidence intervals were calculated. Analyses were made with stratification for year of birth and other risk factors. The risk of developing coeliac disease decreased with maternal age and was lower in first-born than in second-born children. Maternal smoking in early pregnancy was a weak risk factor, as was low birthweight. The most evident risk factors were being exposed to neonatal infections (OR = 1.52, confidence limits 1.19: 1.95) and being small for gestational age (OR = 1.45, confidence limits 1.20; 1.75). These risk factors were independent of each other. CONCLUSIONS We have demonstrated that the intrauterine environment, mainly as mirrored by a low birthweight for gestational age and, independently, neonatal infection diagnosis, is associated with the risk of developing coeliac disease, supporting the idea of a multifactorial aetiology of the disease.

Abstract
OBJECTIVES Celiac disease (CD), a common cause of malabsorption, is known to be associated with disorders of the skeleton, but there are conflicting data about the effect of diet on bone metabolism. The aims of this study were to investigate the prevalence of osteopenia; to identify the relationship between bone mineral density (BMD), serum calcium, and parathyroid hormone levels; and to determine the effect of gluten-free diet on BMD in children with celiac disease. DESIGN The study included 32 patients with CD (group 1) and 82 healthy controls (group 2). The patients with CD were evaluated under 2 subgroups, ie, 16 patients with recent diagnosis (group 1a) and 16 patients who follow their diet strictly (group 1b). BMD values and concentrations of calcium, phosphorus, alkaline phosphatase, and intact parathyroid hormone were determined on entry to the study and at 12 months in celiac patients. These values were compared with those of healthy control participants. RESULTS BMD and bone mineral content values in patients with recent diagnosis were found to be significantly lower than the control group. The BMD values in patients with recent diagnosis were significantly increased after a gluten-free diet for 1 year. Osteopenia was found more commonly in patients with recent diagnosis than patients in whom a gluten-free diet had been instituted. At 1-year follow-up, osteopenia was not resolved with the gluten-free diet, and this was especially true in patients without gastrointestinal manifestation. In patients with recent diagnosis (group 1a), the mean calcium level was found to be lower than the patients who follow their diet strictly (group 1b). There was a positive correlation between calcium level and BMD and bone mineral content. CONCLUSIONS BMD is almost invariably low in newly diagnosed celiac patients in childhood. We therefore recommend that BMD should be evaluated in patients with CD. Strict gluten avoidance promoted a significant increase in BMD. However, values still remained markedly low after 1 year of follow-up in some patients. These patients should be followed for longer periods of time with yearly BMD evaluation, as 1 year of diet therapy was found to be insufficient for osteopenia to be resolved.

Abstract
BACKGROUND Macroamylasemia (MA) is a benign condition caused by circulating macroamylase complexes of pancreatic or salivary amylase bound to plasma proteins, which cannot be cleared by the renal glomeruli. In most cases, the macromolecular amylase represents a complex of normal amylase and either immunoglobulin A or G and may be a specific antigen-antibody complex. Celiac disease (CD) is a permanent intolerance to ingested gluten that results in immunologically mediated inflammatory damage of the small intestinal mucosa. Several recent population-based serologic surveys have shown CD to be a common disorder, possibly affecting 1 in 200 to 250 individuals in most countries studied, including the United States, where overt CD is rare, indicating a high proportion of subclinical disease. The diagnosis of CD currently rests on the histological demonstration of the characteristic lesion in the small intestine and the subsequent clinical response to the introduction of a gluten-free diet. MA associated with CD has been described in adult patients, and in a few cases, MA decreased or resolved after a strict gluten-free diet. A few single cases of MA have been described in childhood, but no association with CD has been reported so far. We report a girl with CD, autoimmune thyroiditis, and MA, in whom CD-related antibodies to amylase and to exocrine pancreas tissue resolved with a gluten-free diet. CASE REPORT An 11-year-old girl was referred for chronic abdominal pain and growth retardation associated with persistent hyperamylasemia and suspected chronic pancreatitis. We confirmed elevated serum amylase, normal serum lipase, and very low 24-hour urine amylase and amylase clearance/creatinine clearance ratio, consistent with MA. Serologic tests for CD were positive, and the diagnosis was confirmed by small bowel biopsy showing subtotal villous atrophy. Thyroid function tests showed a pronounced hypothyroidism, associated with high titers of thyroid microsomal and thyroglobulin antibodies. Screening for other autoantibodies-including antinuclear, islet cell, glutamic acid decarboxylase, protein tyrosine phosphatase islet antigen 512, adrenal gland, and cytoplasmic neutrophil granulocyte antibodies-was negative. A diagnosis of CD, MA, and hypothyroidism attributable to autoimmune thyroiditis was made. A gluten-free diet and oral replacement with L-thyroxine was started with clinical improvement. Serum amylase and amylase clearance/creatinine clearance ratio normalized, consistent with resolution of MA. STUDY DESIGN AND METHODS The patient's serum samples were obtained at the time of CD diagnosis and at 3 and 12 months after instituting a gluten-free diet. Serum samples from 10 consecutive untreated celiac children were disease controls, and 39 participants with no gastrointestinal symptoms and no family history of CD served as healthy controls. The origin of MA as determined by complexes of amylase with circulating immunoglobulins was tested by the measurement of amylase on supernatants after precipitation of immune complexes with either protein A Sepharose or polyethylene glycol. The precipitation of >60% of amylase activity was consistent with the presence of MA. Immunoglobulin G (IgG) and immunoglobulin A (IgA) circulating autoantibodies to amylase were measured using recently developed enzyme-linked immunosorbent assay (ELISA), using porcine amylase as antigen. Results were expressed as arbitrary units (AUs). Statistical analysis was performed by Student's t test for unpaired data. IgA and IgG antibodies to exocrine pancreas tissue were detected by indirect immunofluorescence on human pancreas cryosections. RESULTS Serum immunoprecipitation with either protein A Sepharose or polyethylene glycol reduced amylase activity from 1698 to 89 U/L (94.8%) and to 75 U/L (95.6%), with only marginal reduction in control serum samples. The ELISA for autoantibodies to amylase detected high values, both IgA (3531 AU) and IgG (1855 AU), in the serum sample from the patient at CD diagnosis. IgA autoantibodies (mean +/- standard deviation) were 3.4 +/- 2.5 AU in healthy controls, and 2.1 +/- 1.2 AU in celiac controls; IgG autoantibodies were 10 +/- 4.8 AU in healthy controls and 8.5 +/- 3.2 AU, respectively. Autoantibodies to exocrine pancreas tissue were documented in patient sera at the time of CD diagnosis, both IgA and IgG, but not in control groups. Preincubation of patient's serum with excess of alpha-amylase specifically inhibited antibody binding to coated amylase in the ELISA, and partially inhibited immunoreactivity to exocrine pancreas. Autoantibodies to alpha-amylase and to exocrine pancreas declined in CD patients after institution of a gluten-free diet. CONCLUSIONS Few cases of MA have been described in children, and in all amylase determination was part of the clinical investigation for abdominal pain or trauma. (ABSTRACT TRUNCATED)

Abstract
Celiac disease (CD) is frequently associated with other autoimmune diseases such as Type 1 diabetes mellitus, autoimmune thyroiditis (AT), and Addison's disease. The frequency of these associations varies with the populations studied. We conducted this study to ascertain the prevalence of CD in patients with AT from Sardinia, an area with a very high prevalence of CD. To this aim, 297 consecutive patients with AT (as defined by elevated antithyroid antibody levels and a positive ultrasound scan) were studied. Immunoglobulin A and G-class antigliadin antibodies were assayed in serum; if either or both were positive, antiendomysium antibodies were determined. If two markers were positive, serum ferritin, folate, and vitamin B12 levels were measured and jejunal biopsy was suggested. Thirteen out of the 14 patients who showed at least two positive markers consented to jejunal biopsy and all of them showed histological features of CD. The prevalence of CD in AT patients was 4-fold greater than that observed in the general population (4.37 vs 1.06%, p<0.0001). Ferritin was low in 6 and vitamin B12 in 2 out of 13 patients; serum folates were normal in all patients. Molecular typing of HLA class II alleles showed an increased frequency of the extended haplotype DRB1*0301/DQA1*0501/DQB1*0201. None of our patients had a history of gastrointestinal symptoms. We confirm the increased prevalence of silent CD in patients with AT. Patients with AT ought to be regarded as a high-risk group for CD and should be screened routinely for it; if negative, screening tests should be repeated at regular intervals.

Abstract
A 15-month-old girl with celiac disease presented with microcephaly and developmental delay. Head growth resumed during a gluten-free diet. Subsequent gluten ingestion resulted in no head growth, areflexia, and increased celiac antibodies. All resolved with gluten elimination. Poor head growth may precede other clinical manifestations of celiac disease.

Abstract
An increased incidence of reproductive problems, including infertility, miscarriage, low birth weight newborns, and shorter duration of breast-feeding, are known to exist in women with coeliac disease; some of these conditions are improved by a gluten-free diet. We have tried to ascertain the prevalence of coeliac disease in 99 couples who were being evaluated for infertility, compared with the known prevalence of silent disease in the population of Northern Sardinia, in which it is endemic. Of all women, four tested positive for at least two out of three markers: immunoglobulin A (IgA) antigliadin, immunoglobulin (IgG) antigliadin, and anti-endomysium antibodies, and underwent a jejunal biopsy; three had histological evidence of coeliac disease. One male partner was positive for two markers, and had a diagnostic jejunal biopsy. The prevalence of coeliac disease in infertile women seems higher (three out of 99, 3. 03%) in the study group than in the general population (17 out of 1607, 1.06%), and particularly in the subgroup with unexplained infertility (two out of 25, 8%, P < 0.03). Screening for coeliac disease should be part of the diagnostic work-up of infertile women, particularly when no apparent cause can be ascertained after standard evaluation.
