Prevalence of celiac disease: before and after a national change in feeding recommendations.

OBJECTIVE: A national change in infant feeding recommendations was proposed in 1996 in Sweden: a slow introduction to gluten during weaning was stressed, the recommendation being introduction at 4 instead of 6 months of age. The aim of the present study was to compare the prevalence of celiac disease in healthy young children born before and after the new feeding recommendations in 1996. MATERIAL AND METHODS: Sera from 679 children at a median age of 2.9 years (range 2.5-4.2 years) born between January 1996 and November 1997 were investigated with IgA-antigliadin antibodies (AGA) and IgA-endomysial autoantibodies (EMA) and compared with 690 age-matched children born between July 1992 and June 1993. Children with a positive test for EMA and AGA or EMA only were re-tested, and if positive at follow up, investigated with intestinal biopsy. RESULTS: At baseline, 2.2% (15/679) children were positive for EMA and another 0.6% (4/679) for both EMA and AGA. One child refused to be re-tested and eight children were still EMA positive at follow-up. Intestinal biopsy was performed in seven children (one declined biopsy), of whom three showed total villous atrophy. Two children with EMA titers 1:640, respectively, refused further participation in the study, but were strongly suspected to have celiac disease. In total, 0.7% (5/679) (95% confidence interval (CI) = 0.1-1.4%) were considered to have celiac disease compared with 1.3% (9/690) (95% CI = 0.4-2.2%) in the control group (p=0.4217). In addition, 0.3% of the children were diagnosed with symptomatic celiac disease compared with 0.7% in controls (p=0.0134). CONCLUSIONS: The prevalence of symptomatic celiac disease declined after the infant dietary recommendations were introduced in 1996, but we could not find any difference in undiagnosed celiac disease between the screened children born before and those born after 1996.

IgA antibodies to tissue transglutaminase: An effective diagnostic test for celiac disease.

OBJECTIVE: Tissue transglutaminase (tTG) is the main autoantigen recognized by endomysial antibodies. The aim of this study was to assess sensitivity, specificity, and predictive value of IgA and IgG antibodies to tTG in the diagnosis of celiac disease compared with endomysial antibodies. STUDY DESIGN: We established enzyme-linked immunosorbent assay procedures to measure IgA and IgG antibodies to tTG in sera from 48 untreated and 33 treated patients with celiac disease and from 63 patients with gastrointestinal disease who were in a control group. Sera from 10 patients with celiac disease were examined at various times after gluten was reintroduced into the patients' diet. RESULTS: Both IgA and IgG to tTG were significantly (P <.001) higher in serum of untreated patients with celiac disease versus those in the control group; IgA but not IgG was significantly (P <.001) higher in untreated versus treated patients with celiac disease. IgA and IgG antitissue tTG had a diagnostic sensitivity, specificity, and positive predictive value of 92% and 21%, 98% and 97%, and 98% and 83%, respectively. The concordance rate of IgA anti-tTG with IgA antiendomysial antibodies was 95%. In 5 of the 10 patients undergoing gluten challenge, IgA antiendomysium antibodies were detected earlier than IgA anti-tTG antibodies. CONCLUSIONS: tTG-based enzyme-linked immunosorbent assay is an effective diagnostic test, although immunofluorescent-based assays are more sensitive, particularly during gluten challenge.

The prevalence of liver function abnormalities in pediatric celiac disease patients and its relation with intestinal biopsy findings.

UNLABELLED: Abnormal liver function tests and liver damage are seen frequently with celiac disease. However, the pathogenesis of liver functions abnormality is not clearly understood. The aim of this study was to determine the frequency of abnormal liver functions in children with celiac disease and its relation with anthropometric measurements and severity of intestinal damage. PATIENTS AND METHODS: Twenty seven patients with celiac disease were included in the study. Anthropometric and laboratory examinations and intestinal biopsies were performed in all the patients. Mucosal lesions were classified according to the Marsh classification. Villous area, crypt height and mitotic count were measured morphometrically for all biopsy samples. RESULTS: The mean age of patients was 6 +/- 5 years on admission. Alanine aminotransferase levels were normal (group 1) or elevated (group 2) in 20 and 7 patients, respectively. The mean alanine aminotransferase levels were 22.0 +/- 7.2 in group 1 and 70.5 +/- 31.1 U/L in group 2 patients, (p < 0.001). Complaints, mean age, height for age, weight for height, serum albumin level, villous area, crypt height and mitotic count were not significantly different between the two groups. Similarly, the ratio of Marsh classification was not significantly different between the two groups. All patients were given a gluten-free diet. Serum aminotransferase values returned to normal after 7.4 +/- 2.7 months of a gluten-free diet. CONCLUSION: Abnormalities of liver functions are frequently seen in paediatric celiac disease patients. These abnormalities are not correlated with malnutrition and severity of intestinal mucosal lesions. Liver enzyme activities return to normal levels in a few months after gluten-free diet.

Endoscopic and histological findings in the duodenum of adults with celiac disease before and after changing to a gluten-free diet: a 2-year prospective study.

BACKGROUND AND STUDY AIMS: Published follow-up data on small-intestinal recovery in patients with celiac disease are scarce and contradictory. This is especially the case for adult patients, who often show incomplete histological recovery after starting a gluten-free diet (GFD). We conducted a 2-year prospective study to evaluate the effectiveness of a GFD in improving the endoscopic and histological duodenal findings in adults with celiac disease. PATIENTS AND METHODS: We studied 42 consecutive adults with newly diagnosed celiac disease (13 men, 29 women; mean age 32.7 years, range 15 - 72 years). All the patients underwent esophagogastroduodenoscopy and small-bowel biopsy. We devised our own grading system for the endoscopic appearance of the duodenum, which ranged from "normal" appearance to "mild", "moderate", or "severe" alterations. Small-bowel biopsies were obtained from the second part of the duodenum (and from the duodenal bulb when it had a micronodular appearance). The histopathological appearances were described according to modified Marsh criteria. RESULTS: A normal endoscopic appearance in the duodenum was found in 5/42 patients (11.9 %) at entry and in 32/42 patients (76.2 %) after 2 years on a GFD. Subdividing the patients according to age, patients aged from 15 years to 60 years showed significant improvement within 12 months ( P < 0.0001 for patients aged from 15 years to 45 years; P < 0.003 for patients in the 46 years to 60 years group), whereas the improvement in endoscopic findings in patients older than 60 years was not statistically significant, even 24 months after starting the GFD. "Normal" histology was reported in none of the patients at entry, but in 25 patients (59.5 %) after 24 months on a GFD, but this parameter did not show a significant improvement until the patients had been on the GFD for 12 months ( P < 0.0001). Only the younger patients (5 - 30 years) showed significant improvement of histology within 12 months ( P < 0.034); older patients (>30 years) showed histological improvement but this was not statistically significant, even after 24 months on a GFD. CONCLUSIONS: This study shows for the first time that endoscopic recovery is faster than histological recovery in adults with celiac disease who go on a GFD. Moreover, older patients showed incomplete endoscopic and histological recovery even 24 months after starting a GFD. We therefore advise, as a minimum recommendation, that follow-up biopsies should be taken 1 - 2 years after starting a GFD in adults with celiac disease.

Natural antibiotic expression in celiac disease--correlation with villous atrophy and response to a gluten-free diet.

As infection influences the pathogenesis and presentation of celiac disease, we investigated the expression of natural antibiotics in this condition. Twenty-three adults were prospectively studied: 10 controls and 13 subjects with untreated celiac disease. Distal duodenal biopsies were taken at baseline and after 6 months of a gluten-free diet and assessed for the expression of natural antibiotics. Epithelial human beta-defensin 1 in subjects with celiac disease had a median of 0.02 unit at baseline, compared with 0.34 unit in controls (P < 0.001). It correlated negatively with the degree of villous atrophy (r = -0.64, P = 0.019) and rose to 0.04 unit on the gluten-free diet (P = 0.035 vs. baseline, P < 0.001 vs. controls). The expression of other antibiotics was unchanged. The expression of epithelial natural antibiotics is limited in celiac disease.

Variant mannose-binding lectin alleles are associated with celiac disease.

In this study, we investigated the role of mannose-binding lectin (MBL) in celiac disease, by performing genotype analysis for the three point mutations in the first exon of the gene in 117 Italian celiac patients (characterized by flat biopsy and positive for anti-endomysium antibody and human transglutaminase antibodies) and 130 pan-ethnic healthy controls. The frequency of homozygous mutant 0/ 0 was significantly higher in the 117 Italian celiac patients (0.13) than in the 130 pan-ethnic healthy controls (0.05; P=0.0405). An increased frequency of homozygous 0/0 allele was found among patients with celiac disease compared with controls. These results suggest an involvement of MBL in the pathophysiology of celiac disease.

The serologic screening for celiac disease in the general population (blood donors) and in some high-risk groups of adults (patients with autoimmune diseases, osteoporosis and infertility) in the Czech republic.

The prevalence of celiac disease (CD) was determined in healthy blood donors and in high-risk groups of adults (a total of 1835 adults--randomly selected 1312 healthy blood donors, 102 patients with primary osteoporosis, 58 patients with autoimmune diseases and 365 infertile women). It was calculated on the basis of a two-step serologic screening method--in the first step IgA and IgG antigliadin antibodies (AGA) and IgA anti-gamma-glutamyltransferase ('transglutaminase') antibodies (ATG) were estimated, in the second step sera positive for IgA AGA and/or IgA ATG were examined for antiendomysial IgA (AEA) antibodies. Immunoenzymic assay (ELISA) was used for determining of AGA and ATG antibodies; immunofluorescence method, performed on human umbilical cord tissue, was used for assaying of AEA antibodies. Total serum IgA level in only IgG AGA positive subjects was measured by routine turbidimetric method. 0.45% of healthy blood donors, 0.98% of osteoporotic patients, 2.7% of patients suffering from autoimmune disease and 1.13% of women with infertility considered as immunologically mediated were found to be positive in both steps of serologic screening (AGA and/or ATG and antiendomysium positive). The presumed high prevalence of seropositivity for CD in apparently healthy Czech adult population was confirmed. In the high-risk groups, the prevalence of seropositivity for CD was approximately 2-4 times higher than in healthy blood donors. The real prevalence of CD in the tested groups, however, can be estimated after performing small intestinal biopsy in the seropositive patients.

Mechanisms underlying celiac disease and its neurologic manifestations.

The extra-intestinal manifestations of celiac disease (CD), including ataxia and peripheral neuropathy, are increasingly being recognized as the presenting symptoms of this autoimmune disease. Although there is a greater understanding of the pathogenesis of the intestinal lesions in CD the mechanisms behind the neurologic manifestations of CD have not been elucidated. In this article, the authors review the cellular and molecular mechanisms behind the histopathologic changes in the intestine, discuss the presentation and characteristics of neurologic manifestations of CD, review the data on the mechanisms behind these manifestations, and discuss the diagnosis and treatment of CD. Molecular mimicry and intermolecular help may play a role in the development of neurologic complications.

Brain white-matter lesions in celiac disease: a prospective study of 75 diet-treated patients.

OBJECTIVE: Celiac disease (CD), or gluten sensitivity, is considered to be a state of heightened immunologic responsiveness to ingested gluten proteins in genetically predisposed individuals. The gastrointestinal manifestation suggests a severe enteropathy of the small intestine with malabsorption, steatorrhea, and weight loss because of a deranged mucosal immune response. Neurologic complications occur, especially epilepsy, possibly associated with occipital calcifications or folate deficiency and cerebellar ataxia. There have been reports of brain white-matter lesions as an extraintestinal manifestation in Crohn disease and ulcerative colitis but not in CD. METHODS: In this study, 75 diet-treated mainly pediatric patients with biopsy-proven CD underwent prospectively clinical neurologic examinations, laboratory investigations, electroencephalography, computed tomography, and magnetic resonance imaging. The age range was 2.8 to 24.2 years with a mean of 11.6 years. The mean period of gluten exposure was 2.4 years. RESULTS: Ten patients had neurologic findings such as febrile seizures, single generalized seizures, mild ataxia, and muscular hypotonia with retarded motor development. No folate deficiency was found. The hippocampal regions showed no abnormalities. Computed tomography did not reveal any cerebral calcifications, but magnetic resonance imaging detected unilateral and bilateral T2-hyperintensive white-matter lesions in 15 patients (20%). There was no correlation between these lesions and dietary compliance or neurologic or electroencephalographic abnormalities. The mean gluten exposure time of these patients was slightly increased (not significant). CONCLUSIONS: Focal white-matter lesions in the brain may represent an extraintestinal manifestation of CD. They may be ischemic in origin as a result of a vasculitis or caused by inflammatory demyelination. They seem to be more typical of pediatric CD than cerebral calcifications. Their prognostic value is unclear and needs to be elucidated in additional studies. CD should be suggested as a differential diagnosis in children with unclear white-matter lesions even without intestinal symptoms.

Celiac disease as a cause of chronic pelvic pain, dysmenorrhea, and deep dyspareunia.

BACKGROUND: Celiac disease may be subclinical and difficult to diagnose in adults. It has been associated with infertility and miscarriage but rarely with other gynecologic symptoms. CASE: A 43-year-old woman complaining of chronic abdominal and pelvic pain, deep dyspareunia, dysmenorrhea, diarrhea, and a 5-kg weight loss during the last 6 months was referred to our institution. Laboratory and clinical examinations were negative. At laparoscopy, numerous small leiomyomata were seen. A few filmy adhesions between the small bowel and the abdominal wall were lysed. With the exception of deep dyspareunia, all symptoms remitted after surgery, only to recur at 6 months of follow-up. A diagnostic work-up for celiac disease revealed the presence of antigliadin and antiendomysial antibodies. The diagnosis was confirmed at gastroduodenoscopy including biopsy. A gluten-free diet was prescribed, and the patient is now free of symptoms. CONCLUSION: Celiac disease should be considered in women presenting with unexplained chronic pelvic pain, dysmenorrhea, and deep dyspareunia.

The soluble transferrin receptor (sTfR)-ferritin index is a potential predictor of celiac disease in children with refractory iron deficiency anemia.

The soluble transferrin receptor (sTfR) distinguishes iron deficiency anemia from other types of anemia. Refractory iron deficiency anemia is often the onset symptom in malabsorption-induced celiac disease. We evaluated whether sTfR levels distinguish celiac disease-associated iron deficiency anemia from iron deficiency anemia of other origin. To this aim we measured sTfR and ferritin levels and their ratio (the sTfR/ferritin index) and other hematological parameters in 42 anemic children (20 with and 22 without celiac disease) vs. 22 non-anemic children with celiac disease and 31 healthy controls (age range 4-12 years). Hemoglobin parameters, mean cell volume, and serum iron and ferritin levels were decreased to a similar extent in the anemic patients (celiac and non-celiac). The sTfR level in non-anemic celiac patients was similar to that of normal controls (1.7+/-0.35 mg/L), whereas it was significantly increased in non-celiac and celiac anemic patients (2.2+/-0.5 mg/L, p<0.05 and 2.7+/-1.2 mg/L, p<0.001, respectively). The sTfR/ferritin index was also increased more in the anemic celiac patients (mean 4.4, range 1.5-12.0) than in anemic non-celiac children (mean 2.6, range 1.4-4.0) compared with non-anemic children (mean 1.2, range 0.7-2.0). Differences were more pronounced when ferritin was <5 ng/mL. Thus, the sTfR/ferritin index may be a predictive measure in discriminating anemic patients with celiac disease from those without celiac disease.

Atypical mole syndrome and congenital giant naevus in a patient with celiac disease.

We describe a case of a 28-year-old woman affected by celiac disease (CD) associated with rare multiple disorders of the cutaneous pigmentary system: atypical mole syndrome and congenital giant naevus. Some other rare skin lesions have been reported in association with celiac disease such as cutaneous sarcoidosic granuloma, bullous pemphigoid, ichthyosis, alopecia areata, erythema elevatum diutinum, sclero-atrophic lichen and primary cutaneous amyloidosis. This is the 1(st) report concerning celiac disease and congenital disorders of the pigmentary system.

Heterogeneity of vitamin D receptor gene association with celiac disease and type 1 diabetes mellitus.

OBJECTIVE: Vitamin D has been shown to exert multiple immunomodulatory effects and is known to suppress T-cell activation by binding to the vitamin D receptor (VDR). To determine whether VDR gene polymorphisms are related to the susceptibility to celiac disease, we investigated its implication as a candidate gene in the Basque population. Because celiac disease and type 1 diabetes share common susceptibility loci, we also analyzed families with type 1 diabetes mellitus. METHODS: A total of 37 families with celiac disease and 64 type 1 diabetic families of Basque origin with at least one affected offspring were genotyped for four VDR restriction-site polymorphisms (Fok I, Bsm I, Apa I and Taq I). The AFBAC approach was used to test for association. RESULTS: Comparison of VDR genotypes of the patients with those of 88 healthy individuals identified "ff" as a risk genotype for celiac disease [p = 0.01; OR = 3.45 (1.12-10.79)]. On the other hand, a significantly higher frequency of haplotype "fBAt" was observed in the type 1 diabetic group [p(c) = 0.02; OR = 4.4 (1.5-15.3)]. CONCLUSION: Our findings suggest that polymorphisms within the vitamin D receptor gene are markers of susceptibility to or protection from autoimmune diseases, although, at least in the Basque population, association of VDR variants with celiac disease and type 1 diabetes seems to be heterogeneous.

Gut permeability to human alpha-lactalbumin, beta-lactoglobulin, mannitol, and lactulose in celiac disease.

Our objective was to examine the permeability of the gut to protein macromolecules and sugar probes and their possible association in celiac disease patients. We studied the permeability to human alpha-lactalbumin, beta-lactoglobulin, mannitol, and lactulose on 46 occasions in 33 celiac disease patients in various phases of the disease; in addition, mannitol and lactulose permeability was studied in 18 healthy controls. Lactalbumin absorption was detected in 19 of 42 patients tested, more often in celiac disease patients with villous atrophy than in those with normal jejunal biopsy (p = 0.01). Higher absorption of lactalbumin was found in patients with subtotal villous atrophy than in those with normal biopsy (p = 0.02). beta-lactoglobulin was found in four of 42 patients tested. Less mannitol was absorbed by patients with either subtotal or partial villous atrophy than by those with normal histology (p = 0.001 and 0.006, respectively). Lactulose recovery was higher in newly diagnosed patients and patients with subtotal villous atrophy than in controls (p = 0.007 and 0.03, respectively). The lactulose/mannitol ratio was higher in newly diagnosed patients and patients with villous atrophy than in controls (p = 0.002 and 0.002, respectively). The correlation between permeability to lactalbumin and mannitol and lactulose was poor. We conclude that permeability to proteins and sugar molecules is abnormal in celiac disease patients with mucosal damage and that they probably reflect different mechanisms of penetration.

Celiac disease and irritable bowel-type symptoms.

OBJECTIVES: Previous reports have linked irritable bowel syndrome (IBS) etiologically with various forms of mucosal inflammation, including infectious enterocolitides and inflammatory bowel disease. The mechanism is uncertain but may involve sensitization by inflammatory mediators. The enteropathy of celiac disease has theoretical advantages as a study model because it can be controlled with dietary gluten exclusion; however, whether it also predisposes to functional bowel disorders is unclear. Therefore, we assessed the prevalence of IBS-type symptoms in adult celiac patients and correlated this with dietary compliance with gluten exclusion. METHODS: Adult patients (n = 150; 106 women and 44 men) with confirmed celiac disease were randomly selected from a computerized database of >350 patients, and were asked to complete a bowel questionnaire and the Short Form 36 Health Survey (SF-36). The control group (n = 162; 133 women and 29 men) had no history of celiac disease and had similar mean age and sex profile. RESULTS: Of 150 celiac patients reviewed, 30 of 150 (20%) fulfilled the Rome criteria compared with eight of 162 (5%) ontrols. Of the celiac patients 10 of 46 (22%) had partial or no compliance with a gluten-free diet, whereas 20 of 104 patients (19%) adhered to the diet; this difference did not achieve statistical significance. Celiac patients with IBS-type symptoms had a markedly lower quality of life than those without, all eight domains being impaired to a clinically significant extent. Dietary gluten exclusion improved QOL in four of eight scales measured. CONCLUSIONS: The hypothesis that mucosal inflammation in celiac disease may have a sensitizing effect or may predispose to IBS-type symptoms is supported by these results. Failure to attain optimal subjective well-being is common in celiac patients, particularly in those with coexisting IBS. Compliance with a gluten-free diet confers some benefit.

High prevalence of celiac disease in healthy adults revealed by antigliadin antibodies.

Sera from 1866 healthy blood donors and from 40 untreated adults with celiac disease were analyzed using a micro-ELISA assay. Blood donors with IgA antigliadin activity greater than 40 units corresponding to the 96.8th percentile and IgG antigliadin activity greater than 20 units corresponding to the 91.3rd percentile were selected for further investigation and jejunal biopsy. Seven of 49 blood donors with high IgA antigliadin activity showed mucosal lesions typical for celiac disease. None of the donors with high IgG antigliadin activity (35 subjects) but without high IgA activity had such mucosal lesions. A prevalence of celiac disease of at least 1/256 was observed in the donor group. There were significant age-group differences in IgA antigliadin activity. In the present study, a high IgA antigliadin activity had a positive predictive value between 18% and 25% in individuals without symptoms indicative of celiac disease depending on the way the cut-off points were chosen. In contrast, the positive predictive value of high IgG antigliadin activity alone was estimated to be 0%.

Serologic testing for celiac disease in young adults--a cost-effect analysis.

In recent years, there has been a marked increase in the diagnostic workups for celiac disease among military personnel, thereby significantly increasing overall laboratory testing expenditures and burden. We evaluated the serologic testing procedure in symptomatic young adults, using a "cost-effect" approach. We evaluated the serologic screening policy for celiac disease among serologically tested military personnel. The study population was divided into subgroups according to the clinical presentation prior to screening: isolated (low-risk) and combined complaints (high-risk). Sensitivity, specificity, and predictive values of serologic markers for celiac disease were evaluated. Cost analyses were based on diagnostic expenditures. Cost-effect ratio is expressed as cost per newly diagnosed patients, and cost minimization as cost per screened individuals. Five hundred thirty-eight military personnel were serologically tested for celiac disease. Eight new cases of celiac were diagnosed, all of whom belonged to the high-risk subgroup and tested positive for at least two positive serologic tests (tTG + EMA or tTG + AGA IgG + EMA). EMA Ab measured the highest sensitivity, specificity, and predictive values. Average screening expenditure was U.S. $287 per patient. The lowest cost-effect and cost minimization ratios were achieved by implementing a two-step single-marker screening protocol for high-risk subjects and one-step follow-up for low-risk subjects. Among patient population of young adults, selective diagnostic workup could result in cost-minimization without risking quality of diagnosis. From a cost-effect perspective, implemented screening procedures need to be dependent on subgroup: low-risk, clinical follow-up; and high-risk, serological testing for EMA and, only if positive, possibly a small-bowel biopsy.

Celiac disease and pulmonary hemosiderosis in a patient with chronic granulomatous disease.

We report on a patient with the hitherto undescribed combination of chronic granulomatous disease, pulmonary hemosiderosis, and celiac disease. The hemosiderosis resolved with a gluten-free diet and glucocorticosteroid pulse therapy, but the restrictive lung function pattern remained unchanged. Lung function improved markedly by immunosuppression with daily glucocorticosteroid and azathioprine treatment.
