Presentations of adult celiac disease in a nationwide patient support group

Recent epidemiological studies primarily from Europe document that adult celiac disease often lacks the classic presentation of steatorrhea and weight loss. There are few surveys of adult celiac disease in the United States. We surveyed the large population of a nationwide patient support group to determine their disease presentations. In the initial survey (N = 1032 respondents), the median age at onset was 46 years, and the diagnosis of adult celiac disease was often delayed (median 12 months, with 21% delayed over 10 years). Only 32% of adults were underweight, and only about 50% reported frequent diarrhea and weight loss. A second survey documented that common presenting symptoms were fatigue (82%), abdominal pain (77%), bloating or gas (73%), and anemia (63%). Initial physician diagnoses were often irritable bowel syndrome (37%), psychological disorders (29%), and fibromyalgia (9%). These initial presentations are similar to those in Europe and often resemble irritable bowel syndrome.     

Brief report: Physician awareness of celiac disease

BACKGROUND: Celiac disease is a common disorder (up to 0.7%); however, it is uncommonly diagnosed in the United States. OBJECTIVE: We sought to determine physician awareness of celiac disease. DESIGN: Surveys completed by 2,440 (47%) of 5,191 patients in a support group were analyzed for frequency of diagnosis by physician specialties. Questionnaires were then sent to primary care physicians (PCPs) (n=132) in a southern California county to assess knowledge of celiac disease. RESULTS: In patient surveys, only 11% were diagnosed by PCPs (internists and family physicians) versus 65% by gastroenterologists. Physician surveys (70% response) showed that only 35% of PCPs had ever diagnosed celiac disease. Almost all physicians (95%) knew of wheat intolerance, but few (32%) knew that onset of symptoms in adulthood is common. Physicians were well aware (90%) of diarrhea as a symptom, but fewer knew of common symptoms of irritable bowel syndrome (71%), chronic abdominal pain (67%), fatigue (54%), depression and irritability (24%) or of associations with diabetes (13%), anemia (45%) or osteoporosis (45%), or of diagnosis by endomysial antibody tests (44%). CONCLUSIONS: Lack of physician awareness of adult onset of symptoms, associated disorders, and use of serology testing may contribute to the underdiagnosis of celiac disease. The authors have no conflicts of interest to report. This paper was presented in part at the 68th Annual Meeting of the American College of Gastroenterology, October 10–15, 2004, Baltimore, Md.     

Long-term follow-up of celiac adults on gluten-free diet: prevalence and correlates of intestinal damage

BACKGROUND AND AIMS: Celiac disease is the most common severe food intolerance in the Western world and is due to gluten ingestion in genetically susceptible children and adults. Intestinal biopsy is the golden standard for evaluation of mucosal damage associated with celiac disease. Gluten-free diet is the key treatment for celiac disease. Data on the long-term control of celiac disease are few and limited to small series of patients. The study reports data on the control of celiac disease and on its correlates in a large cohort of celiac adults during long-term treatment with gluten-free diet. METHODS: The study cohort comprises 91 men and 299 women having undergone treatment with a gluten-free diet for at least 2 years and with complete records for visits at the time of diagnosis of celiac disease (baseline). Data collection included gender, age, education, weight, bowel habit, blood hemoglobin, plasma albumin and cholesterol, serum antiendomysium antibodies (EMA), dietary compliance to gluten-free diet (coded as good, low, or very low), and intestinal damage at biopsy (coded as absent, mild, or severe). RESULTS: The duration of follow-up was 6.9 +/- 7.5 years (mean +/- SD, range 2-22 years). At follow-up visit, intestinal damage was absent in 170 patients (43.6%), mild in 127 (32.6%), and severe in 93 (23.8%). At follow-up, intestinal damage was significantly associated with dietary compliance, EMA, and plasma albumin (follow-up value and change value from baseline to follow-up). Baseline education significantly predicted dietary compliance and intestinal damage at follow-up. CONCLUSIONS: Celiac disease is often poorly controlled in the majority of patients on long-term treatment with a gluten-free diet as demonstrated by intestinal biopsy. Lack of adherence to strict gluten-free diet is the main reason of poorly controlled disease in adults. Laboratory and clinical information have a high positive predictive value and low negative predictive value for intestinal damage on long-term treatment. Dietary compliance as assessed by interview is the best marker of celiac disease control due to low cost, noninvasivity, and strong correlation with intestinal damage.     

Adult celiac disease followed by onset of systemic lupus erythematosus

BACKGROUND: Celiac disease has been associated with autoimmune disease (eg, autoimmune thyroiditis) and the appearance of different autoantibodies (eg, antidouble-stranded DNA). Conversely, tissue transglutaminase antibodies have been detected in autoimmune disorders, including systemic lupus erythematosus (SLE), but cases of celiac disease with SLE have been only rarely recorded. METHODS: In this study, 246 patients with biopsy-defined celiac disease were evaluated for a prior diagnosis of SLE on the basis of American Rheumatological Association-defined clinical and serologic parameters. RESULTS: There were 6 patients with celiac disease and SLE, or 2.4%, including 4 females and 2 males. Their mean age at diagnosis of celiac disease was 44.7 years and SLE 50 years. In all patients, the diagnosis of SLE was established from 2 years to more than 10 years after the diagnosis of celiac disease, with a mean of 5.3 years. The celiac disease in all 6 patients responded to a gluten-free diet with histologic normalization of the small intestinal biopsies. Despite this small bowel biopsy response, SLE appeared later in the clinical course of the celiac disease. CONCLUSIONS: This study suggests that SLE occurs far more frequently in biopsy-defined celiac disease than is currently appreciated, and detection may be more likely if the period of clinical follow-up of the celiac disease is prolonged.     

Profile of chronic small-bowel diarrhea in adults in Western India: a hospital-based study.

BACKGROUND: Small-bowel diarrhea is reported to account for 10% of all cases of chronic diarrhea. Data on the etiology and clinical presentation of chronic small-bowel diarrhea in adult Indians is scarce. METHODS: 50 patients (mean age 32.8 years; 26 men) with chronic small bowel diarrhea were evaluated clinically, and investigated to determine etiology. The diagnosis of small-bowel diarrhea was based on history, stool volume and associated symptoms. RESULTS: Abdominal pain (n=22, 44%) and weight loss (n=37, 74%) were the most common symptoms, apart from diarrhea. Anemia (70%) and hypoalbuminemia (48%) were other important biochemical abnormalities. Intestinal tuberculosis (26%) and celiac disease (26%) were the most common causes of chronic small-bowel diarrhea. CONCLUSION: Tuberculosis of intestine and celiac disease are common causes of small-bowel diarrhea in our population. Tropical sprue seems to be a rare cause.     

Celiac disease: variations of presentations in adults.

BACKGROUND: Patients with celiac disease, who remain undiagnosed or asymptomatic in childhood, may present in adulthood with either typical or atypical features. METHODS: In a retrospective analysis, we reviewed the case records of 45 consecutive patients with celiac disease diagnosed in adulthood. The diagnosis of celiac disease was made on the basis of the modified European Society of Pediatric Gastroenterology, Hepatology and Nutrition criteria. The modes of presentation, clinical manifestations, endoscopic features and histological features were analyzed. RESULTS: The mean age of these patients at diagnosis was 28.7 (11.2) years. The median duration of symptoms before diagnosis was 2.5 years (range: 6 months to 40 years). Chronic diarrhea was the presenting manifestation in 20 (44%) patients only. Twenty-two (49%) patients were referred to us by hematologists, endocrinologists or gynecologists for evaluation of refractory anemia in 10 (2.2%), short stature in 6 (13.3%), metabolic bone disease in 2 (4.4%) and secondary infertility or delayed menarche in 4 (8.8%). Intestinal mucosal folds were scalloped in 31 (69%), attenuated in 34 (76%) and normal looking in 11 (24%) of them. Mild, moderate and severe villous abnormalities on intestinal mucosal biopsies were present in 10 (22.2%), 15 (33.3%) and 19 (42.2%) patients, respectively. CONCLUSIONS: More than half of adult patients with celiac disease present with atypical manifestations. A high index of suspicion is required for diagnosing variant forms of celiac disease in adults.     

Undiagnosed celiac disease in childhood

AIMS: This study was designed to assess the proportion of adult patients with celiac disease who had had undiagnosed symptoms during childhood and to determine the consequences of such diagnostic delay. PATIENTS AND METHODS: One hundred eighty-four patients with celiac disease (56 males, 128 females, age range 17-88 years) were classified according to diagnosis and symptoms of celiac disease during childhood. Prevalence of short stature, low fertility, clinical osteoporosis, cancer, and autoimmune disease were assessed in each celiac group and compared with a control group matched for gender and age. RESULTS: Compared with the control group, patients with celiac disease were shorter (men 171.4 +/- 9.0 cm vs 176.4 +/- 6.9 cm, P<0.01; women 159.7 + 7.3 cm vs 162.7 +/- 6.2 cm, P<0.01) and had a higher prevalence of symptomatic osteoporosis (5%) cancer (10%), and autoimmune disease (25%). Compared with matched controls and with patients whose celiac disease had been diagnosed during childhood (n=36), or who had remained symptom-free (n=95), patients who had undiagnosed symptomatic celiac disease during childhood exhibited higher prevalence of short stature (26%), low female fertility or low birth weight (36%). Multivariate analysis showed that short stature and low fertility correlated with duration of symptoms before diagnosis; osteoporosis and cancer correlated with age. The prevalence of autoimmune disease was unrelated to early onset of symptoms or delay to diagnosis. CONCLUSIONS: Missing the diagnosis of celiac disease in a symptomatic child may lead to short stature and low female fertility.     

Duration of exposure to gluten and risk for autoimmune disorders in patients with celiac disease. SIGEP Study Group for Autoimmune Disorders in Celiac Disease.

BACKGROUND & AIMS: The relationship between celiac disease and many autoimmune disorders has been explained by the sharing of a common genetic factor. In a multicenter national study, we examined the relationship between the prevalence of autoimmune disorders in celiac disease and the duration of exposure to gluten. METHODS: Over a 6-month period, 909 patients with celiac disease (group A; mean age, 16.1 +/- 3.8 years; grouped according to age at diagnosis into three subgroups [group A1, <2 years; group A2, 2-10 years; and group A3, >10 years]), 1268 healthy controls (group B; mean age, 20.8 +/- 4.5 years), and 163 patients with Crohn's disease (group C; mean age, 28.8 +/- 10 years) were evaluated for the presence of autoimmune disorders. RESULTS: Prevalence of autoimmune disorders in group A was significantly higher than in group B (14% vs. 2.8%; P < 0.000001) but not higher than in group C (12.9%). Prevalence of autoimmune disorders in celiac disease increased with increasing age at diagnosis: 5.1% in group A1, 17% in group A2, and 23.6% in group A3 (P = 0.000001). In group A3, the prevalence of autoimmune disorders was significantly higher than in group C. In a logistic regression model, age at diagnosis was the only significant predictor variable of the odds of developing an autoimmune disorder (r = 0.3; P < 0.000001). CONCLUSIONS: Our data show for the first time that the prevalence of autoimmune disorders in celiac disease is related to the duration of exposure to gluten.     

A survey of 2,851 patients with hemochromatosis: symptoms and response to treatment.

PURPOSE: Hemochromatosis is a genetic disorder of iron absorption that affects 5 per 1,000 persons and is associated with reduced health and quality of life. We sought to determine the type and frequency of symptoms that patients experienced before the diagnosis and the treatments that they received. METHODS: We mailed a questionnaire to 3,562 patients with hemochromatosis who were located using patient advocacy groups, physicians, blood centers, newsletters, and the Internet. RESULTS: Of the 2,851 respondents, 99% were white and 62% were men. Circumstances that led to diagnosis of hemochromatosis included symptoms (35%), an abnormal laboratory test (45%), and diagnosis of a family member with hemochromatosis (20%). The mean (+/- SD) age of symptom onset was 41 +/- 14 years. Symptoms had been present for an average of 10 +/- 10 years before the diagnosis was made. Among the 58% of patients with symptoms, 65% had physician-diagnosed arthritis and 52% had liver disease. The most common and troublesome symptoms were extreme fatigue (46%), arthralgia (44%), and loss of libido (26%). Physician instructions to patients included treatment with phlebotomy (90%), testing family members (75%), and avoiding iron supplements (65%). CONCLUSIONS: The diagnosis of hemochromatosis in most patients was delayed. Physician education is needed to increase the detection of patients with the disease and to improve its management.     

Enfermedad celiaca en adultos chilenos

Introduction and aimTo characterize a university hospital population of Chilean adult patients with celiac disease.Patients and methodWe retrospectively reviewed the records of patients under control that were diagnosed with celiac disease through clinical characteristics, serology, and histology.ResultsA total of 149 patients were included, 119 (79.9%) of whom were women. Mean patient age was 42 years at diagnosis and 13.4% of patients had a family history of celiac disease. Mean body mass index was 24.3 kg/m², 55.3% presented with normal weight, 37.9% with overweight and obesity, and 6.8% with underweight. The main reasons for consultation were diarrhea (47%), weight loss (31%), dyspepsia (43%), and fatigue (26.1%). Anemia (26.1%), elevated transaminases (17.4%), low ferritin (11.4%), and hypovitaminosis D (9.3%) stood out, among others, in the initial laboratory work-up. The more frequent associated diseases were hypothyroidism (15.4%) and depressive disorder (11.4%). Small intestinal bacterial overgrowth was found in 10.1% and lactose malabsorption in 15.4%. The primary histologic diagnosis was celiac disease, with Marsh stage 3a villous atrophy (34.9%).ConclusionOur results were similar to those of other case series on adults, finding that celiac disease was more frequent in women, disease began in the fourth decade of life, extraintestinal symptoms predominated, and there was an association with other autoimmune diseases. An important percentage of patients were also overweight and obese.     

Celiac disease in South-West of Iran

AIM: Celiac disease is characterized by life-long gluten intolerance. Clinical features of patients with celiac disease are variable. Studies about the prevalence of celiac disease in our country are scarce and there is no study on the prevalence of celiac disease in southern Iran. In the current study, clinical, laboratory and histological features of 52 patients with celiac disease were evaluated. METHODS: In a cross sectional study we retrospectively studied the characteristics of 52 celiac patients at Ahwaz JundiShapour University Hospitals (AJSUH) from November 1, 1999 to 1st Sep 2004. Intestinal biopsy and serum antigliadin and anti-endomysium antibodies were used for the diagnosis of patients. Mucosal lesions were classified according to the criteria of Marsh. Antigliadin antibodies were measured with a commercial enzyme-linked immunosorbent assay. Anti-endomysium antibodies were analyzed by indirect immunofluorescence with the use of a section of monkey esophagus. Routine hematological and biochemical analyses and measurement of immunoglobulin levels were undertaken. RESULTS: Male: female ratio was 1.08. The mean±SD patient age was 21±4.5 years (range 10-70 years) and the most common symptoms were diarrhea and weight loss (78.8%) followed by fatigue (73.1%), pallor (65.4%), anorexia (40.4%), abdominal distention (32.7%), and failure to thrive (23.1%). Diarrhea and weight loss and fatigue were the most common findings. Iron deficiency anemia was found in 63.2% of patients and this became normal after adoption of a gluten-free diet in all patients. Immunoglobulin A, IgG antigliadin antibodies and IgA anti-endomysium antibodies were found in 33 and 48 cases, 78.8% and 85.4% of patients, respectively. Biopsy of the small intestine revealed that 90.4% of patients had typical lesions according to the Marsh classification. CONCLUSION: Although classical presentation was seen in most of the patients, atypical clinical manifestations of celiac disease should be kept in mind. In particular, patients with uncommon findings, such as short stature, and iron-deficiency anemia, should be screened for celiac disease. Further epidemiological studies in our area in the general population and in high risk groups seem to be indicated.     

Adult celiac disease in northern India.

OBJECTIVE: To study the presentation of adult celiac disease in a northern Indian hospital. METHODS: Case records of all patients diagnosed as having adult celiac disease in the Gastroenterology unit of this hospital during January 1996 till December 2001 were reviewed. Celiac disease was diagnosed according to the revised ESPGAN criteria. Adult celiac disease was diagnosed if disease manifestations started after 15 years of age. All patients had a minimum of one-year follow up. RESULTS: The mean duration of illness in the 96 patients (mean [SD] age 32.9 [11.4] years; 50 men) diagnosed over the 6-year study period was 7.3 (2.4) years. Diarrhea was present is 67.7% of cases; 18.7% presented with refractory iron-deficiency anemia, and 9.4% with abdominal symptoms like flatulence and distension. Three patients presented with dysphagia and anemia and were diagnosed as having Plummer-Vinson syndrome. Ulcerative colitis, non-alcoholic steatohepatitis, and aphthous ulcers were associated conditions. All patients had significant improvement in symptoms and hematological and biochemical parameters after dietary gluten restriction. CONCLUSION: Adult celiac disease is not rare and usually presents as diarrhea, abdominal distension and flatulence, and refractory anemia.     

Clinical features and symptom recovery on a gluten-free diet in Canadian adults with celiac disease

BACKGROUND:

Celiac disease can present with mild or nongastrointestinal symptoms, and may escape timely recognition. The treatment of celiac disease involves a gluten-free diet, which is complex and challenging.

OBJECTIVE:

To evaluate clinical features and symptom recovery on a gluten-free diet in a Canadian adult celiac population.

METHODS:

All adult members (n=10,693) of the two national celiac support organizations, the Canadian Celiac Association and Fondation québécoise de la maladie coeliaque, were surveyed using a questionnaire.

RESULTS:

A total of 5912 individuals (≥18 years of age) with biopsy-confirmed celiac disease and/or dermatitis herpetiformis completed the survey. The female to male ratio was 3:1, and mean (± SD) age at diagnosis was 45.2±16.4 years. Mean time to diagnosis after onset of symptoms was 12.0±14.4 years. Abdominal pain and bloating (84.9%), extreme weakness/tiredness (74.2%), diarrhea (71.7%) and anemia (67.8%) were the most commonly reported symptoms at the time of diagnosis. Many respondents continued to experience symptoms after being on a gluten-free diet for >5 years. Sex differences were reported in clinical features before diagnosis, recovery after being on gluten-free diet and perceived quality of life, with women experiencing more difficulties than men.

CONCLUSIONS:

Delays in diagnosis of celiac disease in Canada remain unacceptably long despite wider availability of serological screening tests. Many patients report continuing symptoms despite adhering to a gluten-free diet for >5 years, with women experiencing more symptoms and a lower recovery rate than men. Awareness of celiac disease needs improvement, and follow-up with a physician and a dietitian is essential for all patients with celiac disease.     

Changing presentation of adult celiac disease

The mode of presentation of celiac disease in the United States is not known. We investigated the demographic and clinical features of 227 patients with biopsy-proven celiac disease and determined if there had been changes over time. The patients had been entered into a database; those seen prior to 1990 were retrospectively entered while those seen subsequently were prospectively entered. A symptomatic presentation described the classical presentation of celiac disease with prominent gastrointestinal symptoms: diarrhea and weight loss. Females were younger and had a longer duration of symptoms compared to males. The modes of presentation were symptomatic (62%), anemia or reduced bone density (15%), screening first-degree relatives (13%), and incidental diagnosis at endoscopy (8%). We compared those diagnosed before and after 1993 (when serologic testing was first used), and noted a reduction in those presenting with diarrhea, 73% vs 43% (P = 0.0001) and a reduction in the duration of symptoms, from 9.0 ± 1.1 years to 4.4 ± 0.6 years (P < 0001). In conclusion, the percentage of celiac disease patients presenting with diarrhea has decreased, probably related to the more widespread use of serologic testing for celiac disease.     

The role of hemochromatosis susceptibility gene mutations in protecting against iron deficiency in celiac disease

BACKGROUND & AIMS: Celiac disease and hereditary hemochromatosis are common HLA-defined conditions in northwestern Europe. We sought to determine whether there is a genetic relationship between the 2 diseases and if hemochromatosis susceptibility gene (HFE) mutations are protective against iron deficiency in celiac disease. METHODS: Polymerase chain reaction amplification using sequence-specific primers capable of identifying the 2 HFE gene mutations (H63D and C282Y) and the HLA class I and II alleles was used to type 145 white patients with celiac disease and 187 matched controls. Hemoglobin and fasting serum iron levels in celiac patients were measured at diagnosis. RESULTS: HFE gene mutations, H63D or C282Y, were identified in 70 celiac patients (48.3%) and 61 controls (32.6%) (P = 0.004). The C282Y mutation was associated with HLA-A*03 and B*07 alleles in controls and with A*01, A*03, B*08, and DRB1*0301 alleles in celiac patients; the H63D mutation was associated with HLA-A*25 and DRB1*03 alleles in controls and A*29 and DRB1*03 alleles in celiac patients. At diagnosis, celiac patients with the C282Y mutation had higher mean hemoglobin and fasting serum iron levels compared with the HFE wild type (P = 0.0002 and 0.006, respectively). This was not observed with the H63D mutation. CONCLUSIONS: In celiac disease, HFE gene mutations are common and are in linkage disequilibrium with different HLA alleles compared with controls. A disease-specific haplotype that carries C282Y and DQB1*02 is suggested. We propose that HFE gene mutations provide a survival advantage by ameliorating the iron deficiency seen in celiac patients.     

Development of celiac disease-associated antibodies in offspring of parents with Type I diabetes

Aims/hypothesis. The aim of this study was to determine the frequency and temporal development of antibodies related to celiac disease in offspring of parents with Type I (insulin-dependent) diabetes mellitus. Methods. Sera from 913 offspring of parents with Type I diabetes prospectively followed from birth to the age of 8 years were tested for IgG-transglutaminase antibodies (IgG-tTGCAs), endomysial IgA antibodies (EMA) and gliadin antibodies. Results. We found tTGCAs in 32 (3.5 %) of the 913 relatives. Prevalence was related to age and reached 6.5 % at age 8 years. Endomysial IgA antibodies were detected in 44 % of the relatives with tTGCAs and 0.6 % of tTGCA negative relatives and were also most prevalent (5 %) in those aged 8 years. Both tTGCAs and EMAs were more frequent in relatives with the HLA DRB1^*03 DQA1*0501 DQB1^*02 haplotype (7.1 % and 7.2 %, respectively; p < 0.005). Anti-gliadin antibodies were common in both tTGCA positive (42 %) and negative (23 %) relatives, did not show a relation with age and were less prevalent in relatives with HLA DR3 (p < 0.05). There was no association between the presence of antibodies associated with celiac disease and islet autoantibodies in these relatives. Of the relatives 15 (1.6 %) had tTGCAs plus EMAs. In two of these, anti-gliadin antibodies were detected before the detection of tTGCAs and EMAs at the age of 9 months whereas none of the remainder had any antibodies associated with celiac disease before age 2 years. In three there were no detectable anti-gliadin antibodies in any of the samples tested. Celiac disease without clinical symptoms was diagnosed in 9 of 12 by intestinal biopsy. Conclusion/interpretation. A statistically significant proportion of relatives of patients with Type I diabetes have celiac disease-associated autoimmunity and the silent form of celiac disease early in life. These relatives should, therefore, be considered for celiac antibody screening. [Diabetologia (2000) 43: 1005–1011] Received: 20 January 2000 and in revised form: 26 April 2000     

Non-responsive celiac disease in children on a gluten free diet

BACKGROUNDNon-responsive celiac disease (NRCD) is defined as the persistence of symptoms in individuals with celiac disease (CeD) despite being on a gluten-free diet (GFD). There is scant literature about NRCD in the pediatric population.AIMTo determine the incidence, clinical characteristics and underlying causes of NRCD in children.METHODSRetrospective cohort study performed at Boston Children’s Hospital (BCH). Children < 18 years diagnosed with CeD by positive serology and duodenal biopsies compatible with Marsh III histology between 2008 and 2012 were identified in the BCH’s Celiac Disease Program database. Medical records were longitudinally reviewed from the time of diagnosis through September 2015. NRCD was defined as persistent symptoms at 6 mo after the initiation of a GFD and causes of NRCD as well as symptom evolution were detailed. The children without symptoms at 6 mo (responders) were compared with the NRCD group. Additionally, presenting signs and symptoms at the time of diagnosis of CeD among the responders and NRCD patients were collected and compared to identify any potential predictors for NRCD at 6 mo of GFD therapy.RESULTSSix hundred and sixteen children were included. Ninety-one (15%) met criteria for NRCD. Most were female (77%). Abdominal pain [odds ratio (OR) 1.8 95% confidence interval (CI) 1.1-2.9], constipation (OR 3.1 95%CI 1.9-4.9) and absence of abdominal distension (OR for abdominal distension 0.4 95%CI 0.1-0.98) at diagnosis were associated with NRCD. NRCD was attributed to a wide variety of diagnoses with gluten exposure (30%) and constipation (20%) being the most common causes. Other causes for NRCD included lactose intolerance (9%), gastroesophageal reflux (8%), functional abdominal pain (7%), irritable bowel syndrome (3%), depression/anxiety (3%), eosinophilic esophagitis (2%), food allergy (1%), eating disorder (1%), gastric ulcer with Helicobacter pylori (1%), lymphocytic colitis (1%), aerophagia (1%) and undetermined (13%). 64% of children with NRCD improved on follow-up.CONCLUSIONNRCD after ≥ 6 mo GFD is frequent among children, especially females, and is associated with initial presenting symptoms of constipation and/or abdominal pain. Gluten exposure is the most frequent cause.     

High levels of immunoglobulin A anti-tissue transglutaminase antibodies at diagnosis are a predictive factor for celiac hepatitis

Introduction: Celiac hepatitis is characterized by the presence of liver injury in patients with celiac disease that resolves after gluten-free diet.

Aim: To evaluate predictive factors of celiac hepatitis at celiac disease diagnosis.

Methods: Retrospective study including 46 adult patients with the diagnosis of celiac disease.

Results: Eighty-seven percent were women, with a mean age of 33?±?11 years, 87% had a Marsh 3 and 46% (n?=?21) had celiac hepatitis. These patients had a median Immunoglobulin A anti-tissue transglutaminase antibody (TTG-IgA) level of 208.0?U/ml (p25–p75: 89–1316?U/ml), a mean aspartate aminotransferase of 42?±?24?U/L, alanine aminotransferase 50?±?28?U/L, alkaline phosphatase 111?±?64?U/L, at the time of diagnosis. Median TTG-IgA one year after diagnosis was 9U/ml (p25–p75: 4.5–30.5?U/ml) and 33% of the patients had normal values. At diagnosis, patients without celiac hepatitis had a median TTG-IgA of 77U/ml (p25–p75: 24–288?U/ml), mean aspartate aminotransferase of 23?±?4?U/L, alanine aminotransferase 20?±?6?U/L, alkaline phosphatase 69?±?17?U/L. Median of TTG-IgA one year after diagnosis was 6?U/ml (p25–p75: 3–19?U/ml) and 48% had normal values. The celiac hepatitis group patients had higher values of TTG-IgA (p?=?0.007) at diagnosis. There was a statistically significant positive correlation between TTG-IgA and alanine aminotransferase (r?=?0.324, p?=?0.028) at diagnosis. The odds of having celiac hepatitis was almost 5-fold higher in patients with a TTG-IgA level higher than 310?U/ml (OR?=?4.8, 95%CI?=?1.213–18.781, p?=?0.025).

Conclusions: Higher TTG-IgA levels are a predictive factor for celiac hepatitis in adult patients with celiac disease at diagnosis.
