Celiac disease symptoms in a female collegiate tennis player: a case report.

OBJECTIVE: To present the case of a collegiate tennis player with celiac disease symptoms. BACKGROUND: Celiac disease is a common intestinal disorder that is often confused with other conditions. It causes severe intestinal damage manifested by several uncomfortable signs and symptoms. Failure by the sports medicine staff to recognize symptoms consistent with celiac disease and treat them appropriately can have deleterious consequences for the athlete. DIFFERENTIAL DIAGNOSIS: Irritable bowel syndrome, Crohn disease, Addison disease, lupus erythematosus, juvenile rheumatoid arthritis, lactose intolerance, herpes zoster, psychogenic disorder (depression), fibromyalgia, complex regional pain syndrome, hyperthyroidism, anemia, type I diabetes. TREATMENT: The athlete underwent a series of blood and allergen tests to confirm or refute a diagnosis of celiac disease. When celiac disease was suspected, dietary modifications were made to eliminate all wheat-based and gluten-based products from the athlete's diet. UNIQUENESS: The athlete was able to fully compete in a competitive National Collegiate Athletic Association Division I tennis program while experiencing the debilitating effects associated with celiac disease. The immediacy of symptom onset was notable because the athlete had no history of similar complaints. CONCLUSIONS: Celiac disease is a potentially life-threatening condition that affects more people than reported. A properly educated sports medicine staff can help to identify symptoms consistent with celiac disease early, so damage to the intestine is minimized. Prompt recognition and appropriate management allow the athlete to adjust the diet accordingly, compete at a high-caliber level, and enjoy a healthier quality of life.

Celiac disease in Arabs.

A systematic study of celiac disease in a defined population of Arab children has not been previously reported. We therefore performed a prospective study to determine the incidence and clinical presentation of celiac disease in Jordanian children. A total of 34 (12 boys and 22 girls) cases were diagnosed over a period of 36 months. Nine cases were clustered in three families. The incidence was calculated to be 1:2,800 live births. The mean age at presentation was 4.6 years (range 0.3-13), but it was 8.4 years at the time of diagnosis. Diarrhea was the main initial symptom in 15 (44%) patients. Other signs and symptoms included recurrent abdominal pain in five patients (14%), short stature in four (12%), abdominal distension in three (9%), constipation in three (9%), pallor and recurrent mouth ulcers in two patients each. At the time of diagnosis, 24 (71%) had hypochromic microcytic anemia, and nine (26%) had rickets. The relatively high incidence of celiac disease may be related to the large wheat consumption in this population (135 kg/head/year), and the late onset could be related to the widespread prevalence of prolonged breast-feeding in Jordan (12 months) and late introduction of cereals (6.2 months) in children with late presentation. The delay in diagnosis might be due to the presence of other diseases clinically resembling celiac disease in our community.

[Diagnosis and therapy of celiac disease in adolescence and adulthood].

The incidence of celiac disease has increased considerably during the last two decades. Celiac Disease is now diagnosed in adults at least as frequently as in children. A prevalence of about 1:200 seems reasonable in central Europe. Besides the typical symptomatic presentation, silent, latent and potential celiac disease are found. Oligo- to asymptomatic courses (silent celiac disease) are increasingly found in all age groups. Endomysial antibodies and tissue-transglutaminase antibodies are sensitive and specific for about 95% of celiac patients. However, the final diagnosis is only done by a - mostly endoscopical - biopsy from the distal part of the duodenum, demonstrating hyperplastic villous atrophy of the mucosa with increased numbers of intraepithelial lymphocytes. The biopsies should be classified histologically according to the modified Marsh criteria. Increased prevalence in family members (10 to 15%) and in associated diseases (e.g. diabetes mellitus) lead to the recommendation of active screening in populations at risk. Although the clinical symptoms are rather variable and different, the response to a lifelong strict gluten free diet is nearly 100%. So-called refractory celiac disease is very rare. There are numerous associated diseases as dermatitis herpetiformis, diabetes mellitus type I, thyroid and neurologic diseases. The most frequent complications are retardation of growth in childhood, early onset osteoporosis, and an increased risk of abortions. The most severe complication is intestinal lymphoma. Especially patients with late diagnosis and bad dietary adherence are at risk. A regular follow-up of patients, rather with antibody tests than with duodenal biopsies is recommended to test and secure dietary compliance.

Reversal of low bone density with a gluten-free diet in children and adolescents with celiac disease.

Osteoporosis is a common finding in adult celiac disease patients; however, there are still few data regarding children and adolescents. In the present study we measured the bone mineral density (BMD) in children and adolescents at diagnosis of celiac disease and after approximately 1 y of a gluten-free diet. BMD was measured at the lumbar spine and in the whole skeleton by dual-energy X-ray absorptiometry in 44 celiac disease patients aged 2.58-20.42 y at diagnosis. BMD was also measured in a subset of 25 patients after 1.4 +/- 0.04 y of a gluten-free diet. BMD was compared with that of 177 healthy control subjects aged 1.52-20.99 y. Lumbar spine and whole-body BMD values at diagnosis of celiac disease were significantly lower than in control subjects (P = 0.015 and P = 0.0001, respectively) after differences in age and anthropomorphic variables were controlled for. The subjects studied after the gluten-free diet had BMD values not significantly different from those of control subjects. In conclusion, children and adolescents with celiac disease have remarkably reduced lumbar spine and whole-body bone density. A gluten-free diet promotes a rapid increase of BMD that leads to a complete recovery of bone mineralization. These results emphasize the need for an early diagnosis and treatment in patients with celiac disease to obtain an adequate peak bone mass at the end of puberty.

Celiac disease in adult patients with type 1 diabetes mellitus in Tunisia.

OBJECTIVE: Type1 diabetes mellitus may be associated with celiac disease. The prevalence of celiac disease as determined by screening among adult patients with type 1 diabetes is high with rates of 1.07.8% in Europe and U.S.A. The aims of the study are to determine the prevalence of celiac disease in adults with type 1 diabetes in Tunisia. METHODS: 348 consecutive adult patients with type1 diabetes were investigated prospectively and screened for celiac disease. The mean age was 28.45+/-10.74 years old. There were 176 females and 172 males. For the screening of celiac disease, we used immunoglobulin A (IgA) anti-endomysium (EMA) antibodies determined by an indirect immunofluorescence method. Anti-transglutaminase (tTG) antibodies were determined by an ELISA method. Those patients with positive results for anti EMA and or tTG were proposed for duodenal biopsy. RESULTS: 14 patients were positive for anti EMA and had high or a weak positive level of tTG antibodies. One patient from this group was already known to have celiac disease. Only 8 patients consented to biopsy and morphological changes were consistent with celiac disease in all cases. Prevalence of biopsy-proven celiac disease was 2.3% (95% CI=1.0-4.5%). CONCLUSION: The present study confirms that celiac disease of adults is prevalent in type 1 diabetic patients in Tunisia. Serological screening for celiac disease in type 1 diabetes is important because many patients are asymptomatic and most are detected by the screening.

The prevalence and clinical characteristics of celiac disease in juvenile diabetes in Wisconsin.

BACKGROUND: The relationship between celiac disease and juvenile diabetes has long been known. Only a single study in the United States, from Buffalo, New York, has reported the prevalence of celiac disease in a pediatric diabetic population. This study was conducted to determine the prevalence and clinical presentation of celiac disease in children and adolescents with juvenile diabetes in Wisconsin, USA, using serum antiendomysial antibody as a screening test. METHODS: Two hundred eighteen patients with diabetes (113 males; age range, 4-21 years) and 117 age-and gender-matched control participants were tested for immunoglobulin A endomysial antibody. Patients with positive results were offered a small bowel biopsy. A questionnaire regarding abdominal pain, diarrhea, and growth failure was completed by the parents. RESULTS: Seventeen of 218 diabetic patients (7.7%) had positive endomysial antibody. All control participants had negative results for the endomysial antibody. Small bowel biopsy was performed in 14 patients. Ten patients had villous atrophy. In one patient without villous atrophy, a repeat biopsy 2 years later showed villous atrophy, and two patients had increased intraepithelial lymphocytes without villous atrophy. Seventy percent of the patients with celiac disease were asymptomatic. The reported symptoms were abdominal pain and diarrhea (n = 1) and growth failure (n = 2). Two patients with celiac disease had Down syndrome. CONCLUSIONS: The prevalence of celiac disease in children with juvenile diabetes in Wisconsin is at least 4.6%, which is comparable with European and Canadian studies. Because patients without villous atrophy may have latent celiac disease, the prevalence may be even higher. All children with juvenile diabetes should be screened for celiac disease.

Reduced cadherin/catenin complex expression in celiac disease can be reproduced in vitro by cytokine stimulation.

Celiac disease is characterized by a chronic immune response to dietary gluten, in which T cell responses result in elevated mucosal levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, interferon (IFN)-gamma, and transforming growth factor (TGF)-beta, which induce profound mucosal remodeling associated with increased enterocyte proliferation, apoptosis, and migration. Reduced intestinal expression of the morphoregulatory cell adhesion molecule E-cadherin, which forms complexes with beta-catenin, can increase enterocyte proliferation and migration. However, its mechanism of action in gastrointestinal inflammatory conditions and any involvement in celiac disease is unknown. In this study, we describe changes in E-cadherin and beta-catenin expression in celiac disease tissue and determine the effect of cytokines on their expression in an in vitro model. We assessed E-cadherin and beta-catenin expression in intestinal biopsies from 24 patients with celiac disease, 12 patients with treated celiac disease, and 10 healthy patients by immunohistochemistry, Western blotting, and confocal microscopy. Using Caco-2 cells, we examined the effect of TNF-alpha, IL-1, IFN-gamma, and TGF-beta on E-cadherin expression. E-cadherin transcription was assessed in both intestinal biopsies and Caco-2 cells by in situ hybridization and RT-PCR, respectively. A marked reduction in protein expression of E-cadherin and beta-catenin that returns to normal levels after treatment was observed in celiac disease; this reduction was associated with reduced levels of E-cadherin mRNA. E-cadherin expression in Caco-2 cells was significantly reduced after TNF-alpha, IL-1, and IFN-gamma stimulation. The effect of TNF-alpha on E-cadherin expression was maximal after stimulation for 48 hours and also induced modest reductions in beta-catenin expression. The action of TNF-alpha on E-cadherin was reversible and was shown to act at the transcriptional level. These results demonstrate the novel findings that E-cadherin and beta-catenin expression are reversibly down-regulated in celiac disease and that such changes in epithelial cadherin/catenin complexes may be mediated by cytokines acting on cadherin transcription.

[Prevalence of celiac disease in diabetic children and adolescents].

BACKGROUND: Celiac disease is more common in patients with insulin dependent diabetes than in the general population. AIM: To detect celiac disease in diabetic children and adolescents. PATIENTS AND METHODS: IgA antigliadin, IgG antireticulin and IgG antiendomysium antibodies were measured in 67 diabetic children (35 female), aged between 4 and 18 years old. RESULTS: Only one male adolescent, aged 18 years old, without gastrointestinal symptoms, had a significant elevation of antireticulin and antiendomysium antibodies. His intestinal biopsy showed subtotal villous atrophy, consistent with celiac disease. CONCLUSIONS: The prevalence of celiac disease in these diabetic children is 1:67 (1.5%). Similar figures have been reported elsewhere.

Low plasma cholesterol: a correlate of nondiagnosed celiac disease in adults with hypochromic anemia.

OBJECTIVE: Hypochromic anemia is at times attributable to nondiagnosed celiac disease. The aim of this study was to define the correlates of celiac disease in anemic adults without overt malabsorption. METHODS: One hundred patients with hypochromic anemia and without diarrhea underwent a complete diagnostic work-up, including screening for celiac disease, i.e., upper endoscopy with duodenal biopsy and search of antiendomysium antibodies. RESULTS: Patients with hypochromic anemia were from two different Divisions and were analyzed as a single group because they were not significantly different for any variable. Hypochromic anemia was attributable to celiac disease in 10 patients. Compared to anemic patients without celiac disease, anemic patients with celiac disease had significant or borderline significant differences for plasma cholesterol (-17.9%), albumin (-9.4%), and body mass index (-11.8%), but not for gender distribution, age, weight, height, blood hemoglobin, mean corpuscolar volume, plasma iron, and ferritin. All anemic patients with celiac disease had plasma cholesterol < 156 mg/100 ml. Within the entire cohort of anemic patients, plasma cholesterol inversely related to prevalence of celiac disease (p < 0.001); also plasma albumin and body mass index inversely related to celiac disease, but coefficients were borderline significant (p = 0.056 and 0.052, respectively). CONCLUSIONS: The data suggest that among patients with hypochromic anemia, plasma cholesterol in the high-to-normal range could be used to exclude the presence of celiac disease. Other nutritional markers are less sensitive as indices of risk of celiac disease. Hematological indices are not of help to define the risk of celiac disease in anemic patients without signs of malabsorption.

Bone histomorphometry in celiac disease.

BACKGROUND AND AIMS: Bone metabolism in celiac patients is not well understood and there are no previous histomorphometric studies on bone of patients with celiac disease. The aim of the study was to investigate bone metabolism in celiac patients using bone histomorphometry, measurement of bone mineral density (BMD) and biochemical parameters. MATERIAL AND METHODS: The patient groups included 19 men and 23 women with previously diagnosed celiac disease in remission (group I), 7 women not in remission (group II) and 19 women and 9 men with newly diagnosed celiac disease (group III). Static and dynamic parameters of bone structure, formation and resorption were measured using undecalcified sections. The following parameters were obtained: bone volume (BV/TV; %), osteoid volume (OV/BV; %), osteoid surface (OS/BS; %), resoprtion surface (ES/BS; %), osteoid thickness(Oth; microm), mineral apposition rate (MAR; microm/day), and mineralization lag time (MinLag; day). BMD was measured at the spine (L2-4) and left femoral neck, trochanter and Ward's triangle. Serum calcium (S-Ca; mmol/L), alkaline phosphatase (AP; U/L), intact parathyroid hormone (S-PTH; ng/L), 25-hydroxyvitamin D (S-25(OH)D; nmol/L), cross-linked carboxyterminal telopeptide of human type I collagen (S-ICTP; microg/L) and C-terminal extension peptide of type I procollagen (S-PICP; microg/L) were analysed. RESULTS: In the histomorphometric analysis there were no significant differences in static or dynamic parameters between the groups. Very low bone mass (< 10%) was found in one patient in every group. OV/BV was increased (> 3.5%) in all groups (31% in group I, 13% in group II and 29% in group III). OS/BS was increased (> 36.5%) in groups I and III (17% and 29% respectively). In group II OS/BS was normal in all patients. Mineralization defect was found in four patients in group I and in two patients in group III with otherwise normal histomorphometric results. ES/BS was increased in three patients in group I and III and in one patient in group II. One female patient in group III had increased osteoid parameters, resorption surface, S-PTH and low concentration of vitamin D reflecting hyperparathyroid changes in bone. S-PTH was increased (66-87 ng/L) in four patients in group III and one of these patients had hyperparathyroid histological changes in bone. CONCLUSIONS: Static and dynamic histomorphometry of iliac crest bone biopsy are useful tools to evaluate bone metabolism in celiac disease especially if hyperparathyroidism or mineralization defect are suspected. Hyperparathyroidism may be a problem in the patients before introducing gluten-free diet. Mineralization defect and osteomalacic changes are common later on irrespective of whether the patients are in remission or not.

Plasma cholecystokinin and gallbladder responses to increasing doses of bombesin in celiac disease.

Impaired postprandial gallbladder emptying in celiac disease has been attributed to an absence of appropriate cholecystokinin release. To determine if a flat jejunal mucosa in celiac patients is related to a reduced cholecystokinin-secreting capacity, increasing doses of bombesin were infused into six patients with celiac disease and a flat jejunal mucosa (group A), in seven celiac patients with a normal jejunal mucosa while on a gluten-free diet (group B), and in seven healthy controls (group C). Bombesin induced significant (P < 0.05) increments of plasma CCK to a maximum value of 1.0 +/- 0.3 pM in group A, to 1.5 +/- 0.3 pM in group B, and to 1.2 +/- 0.3 pM in group C (NS between groups), that were accompanied by significant (P < 0.05) gallbladder emptying responses of 70 +/- 4% in group A, 47 +/- 10% in group B and 65 +/- 5% in group C. Dose-response relationships were not different between groups. We conclude that there is no major impairment of gallbladder responsiveness to bombesin or of cholecystokinin-secreting capacity in patients with a flat jejunal mucosa due to celiac disease.

Prevalence and diagnosis of celiac disease in IgA-deficient children.

BACKGROUND: Reported frequencies of celiac disease in selective IgA deficiency in childhood vary widely and this is probably due to the different characteristics of the patients studied and to the different criteria used for intestinal biopsy: all patients or only those with symptoms of malabsorption. Diagnosis of celiac disease is of considerable importance in IgA deficiency because of its increased frequency and also because avoidance of dietary gluten permits elimination of the symptoms and complications of celiac disease. OBJECTIVES: To obtain a more reliable estimate of the incidence of celiac disease in childhood IgA deficiency jejunal biopsies were performed in 65 consecutively diagnosed IgA-deficient children whose parents consented. Some clinical and laboratory parameters including IgA-antigliadin and IgG-antigliadin antibodies were evaluated to predict their usefulness in selecting IgA-deficient patients for intestinal biopsy. METHODS: All IgA-deficient patients had serum IgA levels below 5 mg/dL and salivary IgA below 0.5 mg/dL. Jejunal biopsy was performed using a peroral Watson capsule and IgA-antigliadin and IgG-antigliadin antibodies were performed by an ELISA assay. RESULTS: Biopsy findings of severe villous atrophy permitted diagnosis of celiac disease in 7.7% (5/65 children). IgG-antigliadin antibody levels, elevated in 16 patients including all five celiacs, were the best parameter for predicting celiac disease and gave no false negatives. CONCLUSIONS: The 7.7% frequency of celiac disease observed in these IgA-deficient children is about 20 times higher than in the general Italian population, and the lowest among the studies biopsying all patients; this is probably attributable to the presence of a substantial proportion of healthy children (20/65) and very few (2/65) with autoimmune disorders. The elevated sensitivity and negative-predictive value of IgG-antigliadin antibodies lead us to suggest that positive IgG-antigliadin antibodies can be used to select IgA-deficient children for jejunal biopsy with a very low probability of missing celiac disease while allowing a drastic reduction in the number of biopsies performed.

Association of insulin-dependent diabetes mellitus and celiac disease: a study based on serologic markers.

BACKGROUND: The association of celiac disease and insulin-dependent diabetes mellitus has been known for some time. In an attempt to clarify this association, the prevalence of celiac disease among diabetic children was determined, and the risk of insulin-dependent diabetes mellitus was defined in pediatric patients with celiac disease. METHODS: Ninety-three children with diabetes were analyzed for the presence of celiac disease-related markers (antigliadin and antiendomysial antibodies) and characteristic alterations in the intestinal mucosa. In another group, 93 children with celiac disease were screened for pancreatic autoantibodies and pancreatic beta-cell function. RESULTS: Among children with insulin-dependent diabetes mellitus, a 6.45% prevalence of celiac disease was observed, a value significantly higher than that found among healthy controls. In contrast, only three celiac disease patients showed potential autoimmunity toward the pancreatic beta cell, a proportion not significantly different from that in the general population. Additionally, no alteration of glucose metabolism was observed in the antibody-positive patients. CONCLUSION: The increased risk of celiac disease among patients with diabetes requires a long follow-up to determine the presence of celiac disease markers among patients with diabetes, to avoid potential malignant disease derived from untreated celiac disease. In contrast, there is no evidence to support an increased risk of insulin-dependent diabetes mellitus among children with celiac disease. In accordance with the accepted influence of diet in the development of autoimmune diabetes, a hypothetical mechanism of protection against insulin-dependent diabetes mellitus that is mediated by environmental factors related to restricted diet is suggested in this population.

Celiac disease is highly prevalent in lymphocytic colitis.

A high frequency of celiac disease is reported in patients with collagenous colitis. Limited information is available on the frequency of celiac disease in lymphocytic colitis. The aim of our study was to determine the prevalence of celiac disease in microscopic colitis (collagenous and lymphocytic colitis). Patients were identified from a pathology registry of microscopic colitis from 1987 to 1999. Pathology reports and medical records were reviewed for previous small bowel biopsies and/or celiac serology. We identified 113 patients with microscopic colitis, and 46 patients underwent a small bowel biopsy and/or celiac serology. Of these, 27 patients had lymphocytic colitis (63% female; age, 58.6 +/- 16.2 years) and 19 patients had collagenous colitis (79% female; age, 61.8 +/- 13.6 years). Small bowel biopsy alone was performed in 28 of 46 patients, celiac serology alone was performed in 10, and both small bowel biopsy and celiac serology were performed in 8. Celiac disease was identified in 4 patients by small bowel histology; all had lymphocytic colitis (4 of 27 patients, 15%). This frequency of celiac disease is significantly higher than the highest reported U.S. prevalence of celiac disease (4/1,000 individuals; p < 0.01). There is a high frequency of celiac disease in patients with lymphocytic colitis. Given the importance of the early detection of celiac disease, it should be excluded in all patients with lymphocytic colitis, particularly if diarrhea does not respond to conventional treatment.

Increased prevalence of celiac disease and need for routine screening among patients with osteoporosis.

BACKGROUND: There is an increased prevalence of osteoporosis among patients with celiac disease. However, the relative prevalence of celiac disease among osteoporotic and nonosteoporotic populations is not known, and the benefit of screening the osteoporotic population for celiac disease remains controversial. METHODS: We evaluated 840 individuals, 266 with and 574 without osteoporosis, from the Washington University Bone Clinic by serologic screening for celiac disease. Individuals with positive serologic test results for antitissue transglutaminase or antiendomysial antibody were offered endoscopic intestinal biopsy to confirm the diagnosis of celiac disease. Individuals with biopsy-proven celiac disease were treated with a gluten-free diet and followed up for improvement in bone mineral density. RESULTS: Twelve (4.5%) of 266 patients with osteoporosis and 6 (1.0%) of 574 patients without osteoporosis tested positive by serologic screening for celiac disease. All but 2 serologically positive individuals underwent in-testinalbiopsy. Nine osteoporotic patients and 1 nonosteoporotic patient had positive biopsy results. The prevalence of biopsy-proven celiac disease was 3.4% among the osteoporotic population and 0.2% among the nonosteoporotic population. All biopsy-positive individuals tested positive by antitissue transglutaminase and antiendomysial antibody. The antitissue transglutaminase levels correlated with the severity of osteoporosis as measured by T score, demonstrating that the more severe the celiac disease the more severe the resulting osteoporosis. Treatment of the patients with celiac disease with a gluten-free diet resulted in marked improvement in T scores. CONCLUSIONS: The prevalence of celiac disease among osteoporotic individuals (3.4%) is much higher than that among nonosteoporotic individuals (0.2%). The prevalence of celiac disease in osteoporosis is high enough to justify a recommendation for serologic screening of all patients with osteoporosis for celiac disease.

A major non-HLA locus in celiac disease maps to chromosome 19.

BACKGROUND AND AIMS: The pathogenesis of celiac disease is still unknown despite its well-known association with human leukocyte antigen (HLA)-DQ2 and DQ8. It is clear that non-HLA genes contribute to celiac disease development as well, but none of the previous genome-wide screens in celiac disease have resulted in identification of these genes. METHODS: We, therefore, performed a 2-stage, genome-wide screen in 101 affected sibpairs from 82 Dutch families who met strict diagnostic criteria. The small intestinal biopsy samples, on which the original celiac disease diagnoses had been based, showed a Marsh III lesion in all patients on reevaluation by 1 pathologist. For association analysis of markers in regions linked to celiac disease, 216 independent MIII patients and 216 age- and sex-matched controls were available. RESULTS: As expected, highly significant linkage to the HLA-region was detected (multipoint maximum lod score [MMLS] = 8.14). More importantly, significant linkage was also present at 19p13.1 (MMLS = 4.31), with the peak at marker D19S899. Moreover, this marker was also significantly associated with celiac disease in the case-control study (corrected P = 0.016). Furthermore, we identified suggestive linkage to 6q21-22, which is approximately 70 cM downstream from the HLA region (MMLS = 3.10). CONCLUSIONS: Significant linkage of celiac disease to chromosome region 19p13.1 was detected in our genome-wide screen. These results were confirmed by the association of D19S899 to celiac disease in an independent case-control cohort. Furthermore, we identified a possible second celiac disease locus on chromosome region 6q21-22.

Trends in the presentation of celiac disease.

PURPOSE: Screening studies have revealed that celiac disease is common in the United States; however, there are scant data on the mode of presentation. We analyzed the trends in clinical presentation over the last 52 years in a large cohort of biopsy-proven patients seen in 1 center. SUBJECTS AND METHODS: Patients (n = 590) were divided into 6 groups based on the year of diagnosis (1952-2004). Groups were compared for trends in age at diagnosis, childhood diagnosis, duration of symptoms, mode of presentation (diarrhea, bone disease, anemia, incidental at esophagogastroduodenoscopy, screening), and presence of malignancy. RESULTS: Diagnosis was at an older age since 1980 (P = .007), and there was a significant negative linear trend in patients presenting with diarrhea (P<.001) over time and a positive linear trend in asymptomatic patients detected on screening (P<.001). There was a significant negative linear trend in patients with a malignancy (P = .02) and duration of symptoms before diagnosis of celiac disease (P = .001), although only the subgroup without diarrhea had improvement in delay of diagnosis of celiac disease (assessed by a shorter duration of symptoms) (P = .05). Comparison of patients with and without diarrhea showed no significant difference in age (42.9 years vs 43.7 years, P = .59), gender (29.3% M vs 34.6%, P = .59), and presence of childhood disease (8.0% vs 9.8%, P = .43) or malignancies (9.8% vs 8.9%, P = .71). CONCLUSION: There is a trend toward fewer patients presenting with symptomatic celiac disease characterized by diarrhea and a significant shift toward more patients presenting as asymptomatic adults detected at screening.

Trends in the identification and clinical features of celiac disease in a North American community, 1950-2001.

BACKGROUND AND AIMS: Celiac disease is considered rare in North America. However, an increasing incidence and widening clinical spectrum have been reported in many countries, and serologic screening suggests a higher prevalence of minimally symptomatic disease. This study reports temporal trends in the incidence of celiac disease in Olmsted County, Minnesota. METHODS: All county residents diagnosed with celiac disease between 1950 and 2001 were identified through the Rochester Epidemiology Project. Incidence rates were calculated assuming a Poisson distribution, and changes in incidence by calendar year, age, and gender were assessed by using Poisson regression. RESULTS: Altogether, 82 new cases of celiac disease were identified during the 50-year period. There was a marked female predominance (P < 0.005), and the incidence rates increased with age (P < 0.001) and calendar period (P < 0.001). The overall annual incidence of celiac disease was 2.1 per 100,000 (95% confidence interval [CI], 1.7-2.6) but increased from 0.9 per 100,000 (CI, 0.5-1.2) in 1950-1989 to 3.3 per 100,000 (95% CI, 2.2-4.4) in the 1990s. The incidence was 9.1 per 100,000 (95% CI, 5.2-13.0) in the final 2 years of the study. Serology prompted biopsy in a substantial proportion of recent diagnoses. Clinical features also changed over time, with less diarrhea and weight loss at presentation. CONCLUSIONS: Celiac disease has increased recently in this well-characterized population. Milder clinical features and use of serology suggest an increased detection rate, although a true increase in incidence may have also occurred. Celiac disease is not rare in North America.
