RESUMO
OBJECTIVES: Micronutrient deficiencies characterize classical "late-diagnosed" celiac disease (CeD). This study aimed to identify the prevalence of micronutrient deficiencies among children with "early-diagnosed" screening-identified CeD to determine the clinical value of routine testing for deficiencies in those patients. METHODS: A case-control study was conducted on screening-identified CeD patients diagnosed during a mass screening study (84 patients, mean age 11.3 ± 2.6 years). The controls (443 children, mean age 10.8 ± 2.5 years) were negative for celiac disease serological screening. Hemoglobin, serum levels of iron, ferritin, folate, vitamin B12, vitamin A, vitamin E, 25-OH vitamin D, zinc, and selenium were measured. RESULTS: The mean serum levels of hemoglobin, iron, ferritin, vitamin D, zinc, copper, and selenium were significantly lower in CeD patients than in healthy controls (hemoglobin 12.56 vs. 13.02 g/dL [p = 0.04]; iron 10.61 vs. 17.6 µmol/L [p < 0.001], ferritin 25.7 vs. 48.3 µg/L [p < 0.001], vitamin D 29.1 vs. 37.5 nmol/L, zinc 11.9 vs. 21.7 µmol/L, copper 18.9 vs. 32.5 µmol/L, selenium 1.04 vs. 1.36 µmol/L; p < 0.001). Patients with celiac and severe intestinal damage (Marsh IIIb and IIIc) had significantly lower serum ferritin and vitamin A levels than patients with mild intestinal damage (Marsh II and IIIa) (ferritin 15 vs. 22 µg/L, p < 0.025; vitamin A 0.85 vs. 1.35 µmol/L, p = 0.007). CONCLUSION: Micronutrient deficiencies are still detectable in "early-diagnosed" screening-identified CeD cases, a clinically relevant result that strongly supports efforts for screening and early diagnosis of CeD.

INTRODUCTION: Anemia and micronutrient deficiencies are common in newly diagnosed patients with celiac disease (CeD). We aim to determine the prevalence and etiology of anemia in a cohort of patients with CeD in the United States and examine the effect of a gluten-free diet (GFD) on the laboratory parameters related to anemia in CeD. METHODS: We analyzed a prospectively collected cohort of adults with biopsy-proven CeD followed in a specialized CeD center between January 2000 and June 2016. We used the level of hemoglobin (Hb) and micronutrients suggested by the World Health Organization to establish the diagnosis of anemia or deficiencies. Demographic data and laboratory parameters related to anemia and micronutrients were recorded at the time of diagnosis and on a GFD. A celiac expert nutritionist or gastroenterologist evaluated all patients. RESULTS: In 572 patients with laboratory evaluation before starting a GFD, approximately 25% presented with anemia at the time of diagnosis of CeD. Iron deficiency was present in 50.8% of the cohort and in 78.8% of the patients with anemia. Within the anemic population, 84.4% of female patients as compared with 58.3% of male patients ( P = 0.02) showed iron deficiency. Folate deficiency (23.2%), vitamin B12 deficiency (11%), and anemia of chronic diseases (7.8%) were also part of both sexes' anemia etiology. Of the initially anemic patients, 81% and 89% normalized their Hb levels within 1 year and 2 years of beginning a GFD, respectively. All patients received appropriate supplementation when needed. DISCUSSION: Approximately 25% of individuals have anemia at CeD diagnosis. The anemia etiology included iron deficiency, vitamin deficiencies, and anemia of chronic diseases. Most of the patients will normalize their Hb levels and the anemia laboratory parameters 1 year after starting a strict GFD.

Persons with celiac disease (CD) may develop nutritional deficiencies, while individuals following a gluten-free diet (GFD) may lack essential nutrients. We examined nutrient intake from diet and supplements among persons with CD and GFD in the cross-sectional National Health and Nutrition Examination Survey, 2009-2014. Among 15,610 participants 20 years and older, we identified CD based on positive serology for immunoglobulin A against tissue transglutaminase, health care provider diagnosis, and adherence to a GFD. People without CD avoiding gluten (PWAG) adhered to a GFD without a diagnosis of CD. Two 24-h recalls assessed nutrient intake from diet and supplements. Compared to participants without CD or PWAG, persons with diagnosed CD had lower intake of total energy, carbohydrates, fat, and saturated and monounsaturated fatty acids. In contrast, persons with undiagnosed CD and positive serology had higher intake of those nutrients, sugar, and protein. Total carbohydrate and sugar intake was lower among PWAG. Persons with diagnosed CD had higher vitamin A and E intake, while those with undiagnosed CD had increased intake of calcium, phosphorus, magnesium, iron, zinc, copper, sodium, potassium, vitamin A, alpha-carotene, folic acid, and choline. Higher micronutrient intake with undiagnosed CD was observed more at high latitudes. PWAG had higher beta-carotene and lutein/zeaxanthin and lower folic acid intake. In the U.S. population over a 6-year period, total energy and macronutrient intake was decreased among persons with diagnosed CD, while intake of total energy, macronutrients, and multiple micronutrients was increased among persons with undiagnosed CD. Nutriomics studies of multiple analytes measured simultaneously across affected persons and populations are needed to inform screening for malabsorption and treatment strategies.

BACKGROUND: Coeliac disease (CD) causes deficiency of various micronutrients including vitamin D, and there are no specific guidelines for treatment. AIMS: To determine the prevalence of vitamin D deficiency in children newly diagnosed with CD and the role of oral high-dose vitamin D in its treatment. METHODS: Calcium intake, sun exposure and biochemical and radiological parameters related to vitamin D deficiency were compared between 60 children aged 0-18 years diagnosed with CD and 60 healthy age- and sex-matched controls. The cases with serum 25(OH)D (<20 ng/ml) were given oral vitamin D (60,000 IU/week) and calcium (500 mg/day) for 12 weeks, along with a gluten-free diet (GFD); they were re-evaluated within a week of completion. The primary outcome measure was the serum 25(OH)D level, and secondary measures included serum calcium, phosphorus, alkaline phosphatase, parathormone and clinical and/or radiological rickets. RESULTS: The prevalence of vitamin D deficiency (25(OH)D <20 ng/ml) was significantly greater in the cases (n=38, 63.3%) than in the controls (n=27, 45.0%). Upon treatment, all 38 cases with vitamin D deficiency showed a significant rise in 25(OH)D levels along with normalisation of other biochemical abnormalities. Two children had 25(OH)D levels >100 ng/ml with no other feature suggestive of vitamin D toxicity. CONCLUSIONS: Vitamin D deficiency is more prevalent in children with CD. Administration of oral high-dose vitamin D for 12 weeks along with a GFD leads to a robust response, indicating rapid mucosal recovery. The vitamin D dosage recommended for malabsorption states may be excessive in CD.Abbreviations: ALP: alkaline phosphatase; CaBP: calcium-binding proteins; CD: coeliac disease; GFD: gluten-free diet; PTH: parathormone; RU: reproducibility units; 25(OH)D: 25 hydroxy vitamin D.

BACKGROUND AND AIMS: Patients with celiac disease (CD) commonly use supplements for perceived health benefits despite scant evidence. We aimed to characterize the prevalence and predictors of probiotic use among CD patients. METHODS: We analyzed data from iCureCeliac®; a patient-powered research network questionnaire distributed by the Celiac Disease Foundation. We included adults with self-reported CD who answered questions regarding demographics, diagnosis, symptoms, and treatment. We compared probiotic users versus probiotic non-users and subsequently performed multivariable logistic regression, assessing for independent predictors of probiotic use. RESULTS: 4,909 patients met the criteria for inclusion in the study. Of these, 1,160 (23.6%) responded to a question regarding probiotic use. The mean age of participants was 38.8 years and 82% were female. 381 patients (33%) reported using probiotics. More probiotic users sought nutritional counseling at time of diagnosis (36% vs. 30%, p=0.05) and remained symptomatic despite a gluten-free diet (40% vs. 25%, p <0.001). Probiotic users had lower scores on the pain subscale of the SF36 (63.7±21.6 vs. 69.5±22.1, p=0.006). On multivariable analysis, patients diagnosed after age 50 (OR=2.04, 95%CI: 1.37-3.04), and those with persistent symptoms despite a gluten-free diet (OR=1.94, 95%CI: 1.44-2.63) were more likely to use probiotics. CONCLUSION: In this large study of a national CD registry, roughly one-third of CD patients reported using probiotics. Patients diagnosed later in life were more likely to use probiotics and those who remained symptomatic despite a gluten-free diet were twice as likely to take probiotics. Patients may be seeking additional means of treatment for persistent symptoms.

BACKGROUND AND AIM: Celiac disease (CD) is a chronic disorder resulting from an immune reaction to gluten in genetically predisposed individuals. Although several studies have linked CD to psychiatric diseases, there are limited data on this topic. Using a large database, we sought to describe the epidemiology of several psychiatric disorders in CD. METHODS: We queried a multicenter database (Explorys Inc), an aggregate of electronic health record data from 26 major integrated healthcare systems from 2016 to 2020 consisting of 360 hospitals in the USA. A cohort of patients with a Systematized Nomenclature Of Medicine - Clinical Terms diagnosis of CD was identified. Multivariate analysis was performed using Statistical Package for Social Sciences version 25. RESULTS: Of the 37 465 810 patients in the database between 2016 and 2020, there were 112 340 (0.30%) individuals with CD. When compared with patients with no history of CD, patients with CD were more likely to have a history of anxiety (odds ratio [OR]: 1.385; 95% confidence interval [CI]: 1.364-1.407), depression (OR: 1.918; 95% CI: 1.888-1.947), bipolar (OR: 1.321; 95% CI: 1.289-1.354), attention-deficit hyperactivity disorder (OR: 1.753; 95% CI: 1.714-1.792), eating disorder (OR: 15.84; 95% CI: 15.533-16.154), and childhood autistic disorder (OR: 4.858; 95% CI: 3.626-6.508). Patients with CD and psychiatric conditions were more likely to be smokers, with history of alcohol and substance abuse as well as a history of personality disorder. CONCLUSIONS: In this large database, patients with CD are at increased risk of having multiple psychiatric diseases including anxiety, depression, bipolar, attention-deficit hyperactivity disorder, eating disorder, and childhood autism. Individual care and referral to psychiatry when appropriate are warranted while taking care of this group of patients.

A healthy gut microbiota not only has beneficial effects on the activity of the immune system, but also on thyroid function. Thyroid and intestinal diseases prevalently coexist-Hashimoto's thyroiditis (HT) and Graves' disease (GD) are the most common autoimmune thyroid diseases (AITD) and often co-occur with Celiac Disease (CD) and Non-celiac wheat sensitivity (NCWS). This can be explained by the damaged intestinal barrier and the following increase of intestinal permeability, allowing antigens to pass more easily and activate the immune system or cross-react with extraintestinal tissues, respectively. Dysbiosis has not only been found in AITDs, but has also been reported in thyroid carcinoma, in which an increased number of carcinogenic and inflammatory bacterial strains were observed. Additionally, the composition of the gut microbiota has an influence on the availability of essential micronutrients for the thyroid gland. Iodine, iron, and copper are crucial for thyroid hormone synthesis, selenium and zinc are needed for converting T4 to T3, and vitamin D assists in regulating the immune response. Those micronutrients are often found to be deficient in AITDs, resulting in malfunctioning of the thyroid. Bariatric surgery can lead to an inadequate absorption of these nutrients and further implicates changes in thyroid stimulating hormone (TSH) and T3 levels. Supplementation of probiotics showed beneficial effects on thyroid hormones and thyroid function in general. A literature research was performed to examine the interplay between gut microbiota and thyroid disorders that should be considered when treating patients suffering from thyroid diseases. Multifactorial therapeutic and preventive management strategies could be established and more specifically adjusted to patients, depending on their gut bacteria composition. Future well-powered human studies are warranted to evaluate the impact of alterations in gut microbiota on thyroid function and diseases.

Few studies have examined the role of maternal diet in relation to development of coeliac disease (CD). In Denmark, cancellation of mandatory vitamin D fortification of margarine in June 1985 provided this opportunity. This study examined if season of birth or prenatal exposure to extra vitamin D from food fortification were associated with developing CD later in life. A strength of this study is the distinctly longer follow-up of patients (30 years). This register-based study has a semi-ecological design. Logistic regression analysis was used to estimate odds ratios and to calculate 95% confidence intervals. The odds ratio for developing CD was 0.81 (95% CI 0.66; 1.00 p = 0.054), comparing those with fetal exposure to mandatory vitamin D fortification policy of margarine to those without after adjusting for gender and season of birth. There was a statistically significant season effect particularly for children born in autumn (OR 1.6 95% CI 1.16; 2.21) and born in summer (OR 1.5 95% CI 1.1; 2.1) when compared to children born in winter. Although this study did not find evidence to support the premise that prenatal exposure to small extra amounts of vitamin D from a mandatory food fortification policy lowered risk of developing CD, the small number of CD cases and observed association between season of birth and CD suggest that environmental exposure ought to be further explored.

Background: Adults with celiac disease (CeD) show low bone mineral density (BMD) and high fracture risk. CeD guidelines suggest measurements of serum minerals and vitamin D. However, studies on vitamin levels in CeD patients are contradictory. Aim: To investigate in CeD, 25-hydroxy-vitamin D [25(OH)D], 1,25-dihydroxy-vitamin D [1,25(OH)2D], and related analytes and to evaluate their relationships to peripheral BMD as assessed by peripheral quantitative computed tomography (pQCT). Methods: Gluten-free diet (GFD)-treated, and untreated adult CeD patients naïve to vitamin D and calcium supplementation underwent measurements of serum 25(OH)D, 1,25(OH)2D, parathyroid hormone (PTH), total calcium, phosphate, and of radius BMD by pQCT. Results: Complete data were collected in 105 patients for lab tests and 87 patients for BMD. For lab tests, untreated CeD differed from treated CeD for 22.0% lower serum 25(OH)D (p = 0.023), 42.5% higher serum PTH (p < 0.001), and 13.0% higher serum 1,25(OH)2D (p = 0.029) in the presence of similar serum calcium and phosphorus (p > 0.35). For BMD, untreated CeD differed from treated CeD for lower diaphyseal cortical BMD (1133 and 1157 mg/cm3, p = 0.004) but not for distal BMD (total, trabecular, and subcortical, p > 0.13). Independent correlates of diaphyseal cortical BMD were GFD treatment and body mass index (p < 0.05). Conclusions: Data indicated that, compared to CeD patients on a gluten-free diet, untreated adult CeD patients at diagnosis had lower 25(OH)D, higher PTH, and higher 1,25(OH)2D in the absence of difference in serum calcium and phosphorus. 25(OH)D and 1,25(OH)2D, even below the normal range, were not associated with BMD. Our findings do not support the use of vitamin D supplementation for all CeD adults.

The current study assesses whether the use of a gluten-free diet (GFD) is sufficient for maintaining correct iron status in children with celiac disease (CD). The study included 101 children. The celiac group (n = 68) included children with CD, with long (> 6 months) (n = 47) or recent (< 6 months) (n = 21) adherence to a GFD. The control group (n = 43) included healthy children. Dietary assessment was performed by a food frequency questionnaire and a 3-day food record. Celiac children had lower iron intake than controls, especially at the beginning of GFD (p < 0.01). The group CD-GFD >6 months showed a higher intake of cobalamin, meat derivatives and fish compared to that of CD-GFD <6 months (all, p < 0.05). The control group showed a higher consumption of folate, iron, magnesium, selenium and meat derivatives than that of children CD-GFD >6 months (all, p < 0.05). Control children also showed a higher consumption of folate and iron compared to that of children CD-GFD <6 months (both, p < 0.05). The diet of celiac children was nutritionally less balanced than that of the control. Participation of dietitians is necessary in the management of CD to guide the GFD as well as assess the inclusion of iron supplementation and other micronutrients that may be deficient.

Introduction. Celiac disease, an autoimmune enteropathy, occurs in susceptible individuals and is treatable with a gluten-free diet. These may not be supplemented with vitamins. Objective. To assess the nutritional health of children who have biopsy-proven celiac disease. Methods. Charts were reviewed between July 1, 2007, and June 30, 2017. Results. A total of 252 children ages 0 to 21 years had biopsy-proven celiac disease, mean age 11 ± 4.1 years. Body mass index Z-score was 0.2 ± 1.2 at diagnosis. Except for vitamin D, few had deficiencies at diagnosis. At 1-year follow-up, there was no significant change in anthropomorphics or vitamin status. Adherence to follow-up was poor; at 5 years after diagnosis, 39% adhered to follow-up. Conclusion. Despite a rigorous, proactive protocol for contacting and following children with celiac disease, adherence to follow-up was poor. New strategies, such as follow-up through the primary care provider, are needed.

Gluten-related disorders, including celiac disease, wheat allergy, and nonceliac gluten sensitivity (NCGS), are increasingly reported worldwide. Celiac disease is caused by an immune-mediated reaction to ingested gluten in genetically susceptible persons. NCGS is largely a diagnosis of exclusion when other causes of symptoms have been ruled out. All patients with celiac disease should be referred to a registered dietitian nutritionist with expertise in celiac disease and a gastroenterologist who specializes in celiac disease and malabsorptive disorders, and they should remain on a strict gluten-free diet indefinitely. This article provides an overview of gluten- and wheat-related disorders.

BACKGROUND: Despite the increasing number of publications on celiac disease, there is a lack of studies that made a holistic bibliometric evaluation of the studies on this topic. AIMS: The purpose of this study is to analyze the publications about celiac disease by using bibliometric methods and this way to demonstrate the celiac disease-related trends, top effective articles, journals, and international collaborations between the countries and institutions. METHODS: All articles published between 1980 and 2018 on celiac disease were downloaded from Web of Science and analyzed with bibliometric methods. The correlations between economic development and publication productivity of the countries were investigated with Spearman's rank correlation coefficient. Linear regression analysis was used to estimate the number of publications and citations. RESULTS: The literature review showed that there were 6545 articles about celiac disease published between the years 1980 and 2018. The top productive country that produced most publications about celiac disease was the Italy. The most prolific journals were the Journal of Pediatric Gastroenterology and Nutrition and Scandinavian Journal of Gastroenterology. There was a moderate positive significant correlation between the number of publications and gross domestic product (r = 0.639, p < 0.001). CONCLUSIONS: Despite the advanced research on the diagnosis, pathophysiology, and treatment of celiac disease, the global research level about the disease is low. Therefore, the international collaboration about the disease should not remain at only regional contexts; the exchange of knowledge and common studies especially in developing or underdeveloped countries should be supported in terms of prevalence and clinic studies.

Objective: The aim was to evaluate differences in nutritional intake of calcium, vitamin D, and phosphorus; serologic indices of these nutrients; and bone health among adults with and without probable, undiagnosed celiac disease (CD).Method: Cross-sectional data from What We Eat in America and the National Health and Nutrition Examination Survey 2009-2014 including self-reported dietary and supplement intake from one day of 24-hour recalls, serologic indicators, and dual x-ray absorptiometry scans were analyzed in adults with probable undiagnosed CD, who tested positive on the immunoglobulin A endomysial antibody assay (n = 48) and controls (n = 13,634). Statistical analysis included multiple linear regression modeling controlled for age, sex, race/ethnicity, energy intake, and poverty income ratio.Results: The prevalence of probable undiagnosed CD was 1 in 285. Probable CD status was associated with a 251.6 mg (95% confidence interval [CI], 72.3-432.9) higher daily total calcium intake. The total dietary and supplement intake of those with probable CD was significantly higher in calcium density (103.4 mg/1,000 kcal; 95% CI, 25.6-181.1) and phosphorus density (46.7 mg/1,000 kcal; 95% CI, 3.1-90.3). Probable CD status was associated with higher dairy consumption by 0.7 cups per day (95% CI, 0.2-1.2) and higher serum phosphorus concentrations (4.0 mg/dL vs 3.8 mg/dL, p = 0.011). No differences in serum calcium, vitamin D, or alkaline phosphatase levels were observed between groups. Probable CD status was also associated with a -0.1 g/cm2 (95% CI, -0.2 to -0.0) lower femur bone mineral density (BMD) and a -0.1 g/cm2 (95% CI, -0.1 to -0.0) lower femoral neck BMD. No differences in total spine BMD were observed.Conclusions: Adults with probable undiagnosed CD had lower bone density than adults without CD, despite also reporting higher total calcium intake and nutritional density of both calcium and phosphorus.

Probiotics are linked to positive regulatory effects on the immune system. The aim of the study was to examine the association between the exposure of probiotics via dietary supplements or via infant formula by the age of 1 year and the development of celiac disease autoimmunity (CDA) and celiac disease among a cohort of 6520 genetically susceptible children. Use of probiotics during the first year of life was reported by 1460 children. Time-to-event analysis was used to examine the associations. Overall exposure of probiotics during the first year of life was not associated with either CDA (n = 1212) (HR 1.15; 95%CI 0.99, 1.35; p = 0.07) or celiac disease (n = 455) (HR 1.11; 95%CI 0.86, 1.43; p = 0.43) when adjusting for known risk factors. Intake of probiotic dietary supplements, however, was associated with a slightly increased risk of CDA (HR 1.18; 95%CI 1.00, 1.40; p = 0.043) compared to children who did not get probiotics. It was concluded that the overall exposure of probiotics during the first year of life was not associated with CDA or celiac disease in children at genetic risk.

This guideline presents recommendations for the management of coeliac disease (CD) and other gluten-related disorders both in adults and children. There has been a substantial increase in the prevalence of CD over the last 50 years and many patients remain undiagnosed. Diagnostic testing, including serology and biopsy, should be performed on a gluten-containing diet. The diagnosis of CD is based on a combination of clinical, serological and histopathological data. In a group of children the diagnosis may be made without biopsy if strict criteria are available. The treatment for CD is primarily a gluten-free diet (GFD), which requires significant patient education, motivation and follow-up. Slow-responsiveness occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms necessitate a review of the original diagnosis, exclude alternative diagnoses, confirm dietary adherence (dietary review and serology) and follow-up biopsy. In addition, evaluation to exclude complications of CD, such as refractory CD or lymphoma, should be performed. The guideline also deals with other gluten-related disorders, such as dermatitis herpetiformis, which is a cutaneous manifestation of CD characterized by granular IgA deposits in the dermal papillae. The skin lesions clear with gluten withdrawal. Also, less well-defined conditions such as non-coeliac gluten sensitivity (NCGS) and gluten-sensitive neurological manifestations, such as ataxia, have been addressed. Newer therapeutic modalities for CD are being studied in clinical trials but are not yet approved for use in practice.

INTRODUCTION: We identified the frequency and assessed the validity of marketing claims made by American chiropractors, naturopaths, homeopaths, acupuncturists, and integrative medicine practitioners relating to the diagnosis and treatment of celiac disease and nonceliac gluten sensitivity (NCGS), both of which have increased in prevalence in recent years. METHODS: We performed a cross-sectional study analyzing websites of practitioners from 10 cities in the United States and analyzed the websites for any mention of celiac or NCGS as well as specific claims of ability to diagnose, ability to treat, and treatment efficacy. We classified treatments promoted as true, false, or unproven, as assessed independently by 2 authors. RESULTS: Of 500 clinics identified, 178 (35.6%) made a claim regarding celiac disease, NCGS, or a gluten-free diet. Naturopath clinic websites have the highest rates of advertising at least one of diagnosis, treatment, or efficacy for celiac disease (40%), followed by integrative medicine clinics (36%), homeopaths (20%), acupuncturists (14%), and chiropractors (12%). Integrative medicine clinics have the highest rates of advertising at least one of diagnosis, treatment, or efficacy for NCGS (45%), followed by naturopaths (37%), homeopaths (14%), chiropractors (14%), and acupuncturists (10%). A geographic analysis yielded no significant variation in marketing rates among clinics from different cities. Of 232 marketing claims made by these complementary and alternative medicine (CAM) clinic websites, 138 (59.5%) were either false or unproven. DISCUSSION: A significant number of CAM clinics advertise diagnostic techniques or treatments for celiac disease or NCGS. Many claims are either false or unproven, thus warranting a need for increased regulation of CAM advertising to protect the public.

BACKGROUND & AIMS: According to guidelines, individuals with symptoms of celiac disease should undergo duodenal biopsy analysis to establish a diagnosis, but little is known about physician adherence to these guidelines. We used a patient-powered research network (PPRN) to compare demographics, diagnoses, symptoms, and treatment between groups of patients with celiac disease diagnosed by biopsy analysis and patients with a diagnosis based on results of serology tests. METHODS: We analyzed data from iCureCeliac-a voluntary, PPRN hosted and distributed by the Celiac Disease Foundation, from January 30, 2016, through August 25, 2016. We compared data from adults with a diagnosis of celiac disease (mean age, 43.4 years; 85.6% female) based on biopsy analysis (n = 780) vs patients with a diagnosis based on only serologic analysis (n = 202) using univariate and multivariable analyses. We collected demographic information, as well as data on type of health care practitioner, where patients obtain their primary information about celiac disease, and the Celiac Disease Quality of Life score, nutritionist referral rates, adherence to the gluten-free diet, ongoing symptoms and use of supplements. RESULTS: Among patients with a diagnosis based on serology results, 33.3% were diagnosed by non-gastroenterologists vs 20.7% in the biopsy diagnosed group (P < .001). Fewer patients with a diagnosis based on serology results sought nutritional counseling at the time of diagnosis (40.1%) than patients with a diagnosis based on biopsy (58.9%) (P < .001). A higher proportion of patients diagnosed by serology without biopsy took dietary supplements to aid in digestion of gluten (19.8%) than patients with a diagnosis based on biopsy (8.9%) (P < .001). After we adjusted for age and sex, patients with a diagnosis based on serology were less likely to seek nutritional counseling after diagnosis (odds ratio [OR], 0.45; 95% CI, 0.33-0.63), less likely to receive a diagnosis from a gastroenterologist (OR, 0.16; 95% CI, 0.07-0.37), and more likely to use digestive supplements (OR, 2.61; 95%, CI 1.62-4.19). CONCLUSIONS: In an analysis of data from a PPRN, we found that 21% of adult participants with celiac disease did not have a diagnosis based on a duodenal biopsy. Patients with a diagnosis based on serology results were more likely to be diagnosed by non-gastroenterologists, less likely to seek nutritional counseling, and more likely to use dietary supplements. Patients require more education about management of celiac disease and referral to gastroenterologists for duodenal biopsy confirmation of their disease.

AIM: To evaluate the yield of routine laboratory tests and Dual Energy X-ray Absorptiometry (DEXA) scans in coeliac disease. METHODS: A retrospective analysis of medical files of all followed-up patients with coeliac disease attending Rijnstate Hospital in 2016 was conducted with respect to blood tests of hemoglobin, vitamin B12, folate acid, iron status, calcium, vitamin D, glucose, thyroid function, DEXA-scans and related symptoms or signs of abnormalities. All patients had positive coeliac serology and/or biopsy-proven coeliac disease and attended regular visits after diagnosis. The chi-square test for trend was used for statistical analysis: a two-tailed probability of p < 0.05 was considered significant. RESULTS: We analyzed 250 patients with a median follow-up of 7.8 (1-22) years. At diagnosis, we found anemia in 24.4%, iron deficiency in 38%, folic acid deficiency in 22.6% and vitamin B12 deficiency in 15.9%. All deficiencies recovered within 1-2 years with or without supplements. Deficiencies or autoimmune diseases occurred in 50 patients (37 possibly coeliac-related) during follow-up. Twelve cases of coeliac-related deficiencies or autoimmune diseases occurred in patients with normal values at diagnosis of whom 10 were asymptomatic (incidence 10/1000 patient years). Osteoporosis and osteopenia were present in 23.3% and 35% at diagnosis. In most patients bone mineral density (BMD) improved or stabilized during follow up (p < 0.05), 8% deteriorated. CONCLUSIONS: The incidence of asymptomatic coeliac-related deficiencies or autoimmune diseases is low in patients with normal values at diagnosis. Therefore, routine laboratory screening is not necessary in this group: attending regular follow-up visits should be sufficient. DEXA scans are recommended.
