Impact of FODMAP Content Restrictions on the Quality of Diet for Patients with Celiac Disease on a Gluten-Free Diet. Nutrients 2019; 11:nu11092220. [PMID: 31540014 PMCID: PMC6770200 DOI: 10.3390/nu11092220] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 09/05/2019] [Accepted: 09/11/2019] [Indexed: 12/12/2022] Open
Abstract
Restrictive diets as gluten-free (GFD) or reduced in Fermentable, Oligosaccharides, Disaccharides, Monosaccharides, and Polyols (FODMAP) are used to improve gastrointestinal (GI) symptoms in sensitive individuals. Aiming at comparing the nutritional quality and effects of a regular GFD regimen (R-GFD) and a low-FODMAP GFD (LF-GFD), in 46 celiac patients with persistent GI symptoms we conducted a randomized, double-blind intervention-controlled study. Patients received a personalized diet, either a strict GFD (n = 21) or a LF-GFD (n = 25) for 21 days. A validated food-frequency questionnaire before intervention and a 7-day weighed-food record after the intervention assessed the diets. Patients were 41.1 ± 10.1 years (mean ± SD), 94% women, with mean BMI 21.8 ± 2.9 kg/m2. On day 21, patients on R-GFD still showed poor nutritional adequacy compared to dietary recommendations, with decreased energy intake, even though an improvement in carbohydrates and folates was observed (all p < 0.025). In both groups, intake of iron, calcium, vitamin D, sodium and folates did not meet daily recommendations. As expected, consumption of legumes and grains was lower and that of fruits was higher in the LF-GFD group than in the R-GFD one (all p < 0.05). The nutritional quality of both diets was not different. When restrictive diets are useful to improve the persistent GI symptoms, careful nutritional surveillance and counseling is mandatory.

Abstract
BACKGROUND Celiac disease (CD) is a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten in genetically susceptible individuals. CD-related enteropathy leads to multiple nutritional deficiencies involving macro- and micronutrients. Currently, medical nutrition therapy consisting of the gluten-free diet (GFD) is the only accepted treatment for CD. KEY MESSAGES The GFD is the cornerstone of treatment for CD. Prior published studies have concluded that maintenance of the GFD results in improvement of the majority of nutritional deficiencies. In the past, counseling for CD focused mainly on the elimination of gluten in the diet. However, the GFD is not without its inadequacies; compliance to the GFD may result in certain deficiencies such as fiber, B vitamins, iron, and trace minerals. Paucity of fortified gluten-free foods may be responsible for certain deficiencies which develop on the GFD. Weight gain and obesity have been added to the list of nutritional consequences while on the GFD and have been partially attributed to hypercaloric content of commercially available gluten-free foods. Follow-up of patients diagnosed with CD after starting the GFD has been reported to be irregular and, hence, less than ideal. CONCLUSIONS Monitoring of the nutritional status using blood tests and use of appropriate gluten-free supplementation are integral components in the management of CD. The ideal GFD should be nutrient-dense with naturally gluten-free foods, balanced with macro- and micronutrients, reasonably priced, and easily accessible. Rotation of the pseudo-cereals provides a good source of complex carbohydrates, protein, fiber, fatty acids, vitamins and minerals. Fortification/enrichment of commonly consumed gluten-free commercial grain products should be encouraged. Dietitians specializing in CD play a critical role in the education and maintenance of the GFD for patients with CD.

[PMID: 23891042 DOI: 10.1016/j.mehy.2013.06.025] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Revised: 06/15/2013] [Accepted: 06/22/2013] [Indexed: 12/14/2022]
Abstract
Although a range of neurological and psychiatric disorders are widely reported to be associated with coeliac patients, their pathogenesis remains unclear. Some such disorders are believed to be secondary to vitamin deficiency due to malabsorption, others to immune mechanisms. We hypothesise that hyperhomocysteinemia might, by damaging the blood-brain barrier, expose neuronal tissue to all neuro-irritative metabolites, such as homocysteine itself, a neurotoxic excitatory and proconvulsant amino acid. Neurons respond to these stimuli through hyperexcitability, thereby predisposing subjects to neurological disorders such as epilepsy and headache. Furthermore, persisting endothelial damage may cause blood extravasation and subsequent deposition of calcium salts. We suggest that this might be the pathogenesis of the CEC syndrome, which is characterized by the association of coeliac disease, epilepsy and cerebral calcifications. Indeed, homocysteine plays a well-known role in cardiovascular endothelial dysfunction, with high serum and cerebrospinal fluid levels often being reported in coeliac patients. Moreover, data in the literature show a strong, growing association of homocysteine with epilepsy and migraine in non-coeliac subjects. Despite these findings, homocysteine has never been held directly responsible for neuronal functional features (neuronal hyperexcitability underlying epilepsy and migraine) and structural brain damage (expressed as cerebral calcification) in coeliac patients. Damage to the blood-brain barrier might also facilitate immune reactions against neuronal tissue to a considerable extent. This hypothesis combines the two afore-mentioned theories (vitamin deficiency due to malabsorption and immune mechanisms). We also wish to point out that no studies have yet investigated the prevalence of neuronal hyperexcitability and subclinical electroencephalic abnormalities in children and adults with newly-diagnosed coeliac disease before the introduction of a gluten-free diet, and in particular any changes following the introduction of the diet. We believe that the onset of clinical symptoms such as migraine and convulsions is preceded by a period in which damage is expressed exclusively by subclinical electroencephalic abnormalities; persisting damage to neuronal tissue subsequently leads to clinical manifestations. We propose two types of investigations: the first is to determine whether newly-diagnosed coeliac patients with hyperhomocysteinemia are a subgroup at risk for neurological features (clinical and subclinical); the second is to determine whether appropriate treatment of hyperhomocysteinemia and vitamin B status deficiency improves neurological abnormalities and reduces the risk of cerebral calcifications. The aim of these investigations is to develop new therapeutic strategies designed to prevent neuronal damage and increase the quality of life in children affected by such disorders.

Abstract
OBJECTIVE To examine whether the perceived poor outcome of dietary treatment makes Swedish women with coeliac disease (CD) prone to use more health care services than other women. MATERIAL AND METHODS The health care consumption over 36 consecutive months was examined for 137 Swedish women aged 20-80 years with CD in remission after living on a gluten-free diet for a median of 4 years (range 1-8 years). Comparisons were made with the health care consumption of 411 women in the general population matched for age and residence. RESULTS The results show that women with CD use health care services annually a median of 5.0 times (range 0-76) that is more than female controls 3.6 (0-311) (p < 0.05) mainly in primary care and for complaints related to mental and behavioral disorders (ICD F), diseases of the digestive system (ICD K) and diseases of the musculoskeletal system and connective tissue (ICD M). CONCLUSIONS Women with CD used health care services in keeping with studies indicating reduced health-related quality of life of people with this condition. The results provide evidence that women with CD in remission suffer from co-morbidities that may signal a need for a multidisciplinary follow-up of subjects with CD in Sweden.

Abstract
OBJECTIVES Immunoglobulin A (IgA) autoantibodies to tissue transglutaminase (tTG) are commonly used for screening and diagnosing of celiac disease. We examined the hypothesis that elevated IgA anti-tTG antibodies were associated with higher all-cause mortality risk. METHODS The cohort, 2333 men and 2300 women, was based on the follow-up of participants of a representative population-based survey in Southern Germany (KORA/MONICA Augsburg project) conducted in 1989-1990. The endpoint for the vital status with cause of death was the year 1998. The sera drawn at baseline and stored at -80 degrees C, were recently screened with an IgA enzyme-linked immunosorbent assay (ELISA) using human recombinant tTG. Age-standardized mortality rates and age-adjusted hazard ratios were calculated. RESULTS From the 4633 sera analyzed, 63 had an IgA anti-tTG concentration>or=7 AU/ml. Of these 63 individuals, 15 died between 1989 and 1998. The age-adjusted hazard ratio (HRa) of all-cause mortality was 1.86 (95% CI: 1.01-3.41) and 3.92 (95% CI: 1.44-10.71) for men and women, respectively. The excess of cancer mortality was even higher with an HR(a) of 2.47 (95% CI: 0.89-6.83) in men and of 6.65 (95% CI: 2.04-21.63) in women. CONCLUSIONS Individuals with elevated IgA anti-tTG antibodies had a highly increased mortality risk, particularly due to cancer. New studies are necessary to clarify if this increased risk is due to undiagnosed celiac disease or/and if this elevated IgA anti-tTG antibodies level is a marker of serious diseases like cancer, chronic liver disease or end-stage heart failure.

Abstract
Intestinal intraepithelial lymphocytes (IELs) belong to a unique T-cell population interspersed between epithelial cells of both the small and large intestine. It is becoming increasingly recognised that an increased number of IELs with a normal villous architecture is within the wide spectrum of histological abnormalities observed in coeliac disease. An increased number of IELs is the earliest pathological change following gluten challenge and a high IEL count may be the only sign of gluten sensitivity. Therefore, the finding of a raised IEL count with normal villous architecture is of sufficient clinical importance to be reported in routine small bowel biopsies. However, it is evident that not all small intestinal biopsy specimens showing increased IELs are explained by gluten sensitivity. Increased IELs in small bowel mucosa have also been associated with autoimmune disorders, tropical sprue, food protein intolerance, Helicobacter pylori-associated gastritis, peptic duodenitis, parasitic and viral infections, as well as the development of intestinal lymphoma. Histological examination of a biopsy specimen of the small bowel remains the diagnostic gold standard for coeliac disease. There will be an ever increasing demand for histological confirmation of gluten sensitivity in patients in whom the classic microscopic appearance of flattened villi may not have fully developed. The more widespread recognition by histopathologists of the pattern of injury manifested by increased numbers of IELs in intestinal biopsy specimens will certainly help in early diagnosis of coeliac disease, lessen diagnostic confusion and influence the modern practice of gastrointestinal tract medicine. This review discusses some of the recent developments in clinical pathology pertaining to increased IELs in small bowel mucosal biopsies.

Abstract
Celiac disease (CD) is characterized by malabsorption of nutrients in the small intestine. The availability of highly specific and sensitive serologic tests has facilitated its diagnosis, increasing the disease prevalence. The aim of this study was to determine the clinical, laboratory, and histopathological features of CD in Turkish adults. Between 1968 and 2002, CD patients presenting to the Gastroenterology Unit were evaluated retrospectively. From 2002, newly diagnosed patients were prospectively followed up. Sixty patients (39 female, 21 male) were included in the study. Mean body mass index was 22.2 +/- 5.4 kg/m2. The most common symptoms were diarrhea, weight loss, and flatulence. Most common comorbidities were anemia, osteoporosis, type 1 diabetes mellitus, and steatohepatitis. Six (10.0%) patients had a family history of diabetes mellitus; one (1.7%) patient had a family history of CD. Plasma glucose and serum gamma-glutamyltransferase levels were significantly higher in females than males. Most common histopathological findings were increased lymphocytes in the lamina propria (76.2%) and villus epithelium (59.5%). Over the years, the cumulative frequency of CD increased more in females than males. This is the first study in the literature showing the characteristics of CD in Turkish adults. In our previous recent study, the prevalence of tissue transglutaminase antibody positivity in Turkish healthy blood donors was 1.3%, indicating a high prevalence of CD in our population. In this study, the cumulative frequency of CD increased more in females than males. With the better understanding and increased suspicion of the disease, more patients are being diagnosed in our population.

Abstract
BACKGROUND Iron deficiency anaemia (IDA) is a recognised feature of coeliac disease in adults and can be its only presentation. OBJECTIVE To determine the yield of routine distal duodenal biopsies in diagnosing coeliac disease in adult and elderly patients with IDA whose endoscopy revealed no upper gastrointestinal cause of iron deficiency. STUDY DESIGN Prospective study in a teaching hospital endoscopy unit. METHOD Altogether 504 consecutive patients with IDA, aged 16-80 years, attending for endoscopy were included in this study. At least two distal duodenal biopsies were taken if endoscopy revealed no cause of iron deficiency. RESULT In nine (1.8%) patients duodenal biopsies revealed typical histological features of coeliac disease. Of these, five patients were above 65 years old. CONCLUSION In adult and elderly patients undergoing endoscopy for IDA, the endoscopist should take distal duodenal biopsies to exclude coeliac disease if no upper gastrointestinal cause of anaemia is found. Coeliac disease is not an uncommon cause of IDA in patients >65 years of age and a history of chronic diarrhoea increases diagnostic yield in this age group.

Abstract
Gluten-free diet (GFD) protects against the complications of celiac disease (CD). However, training in the dietetic field is rare in Germany. Thus, CD patients are likely to benefit from a computer-based interactive training program (CBITP) combined with interactive exercises. We compared a CBITP and a conventional training for CD patients regarding increased knowledge, transferability and sustainability. In that context we analyzed whether CD patients are more able to judge the risk of a food or a situation after practicing with the interactive training software. Sixty-four CD patients were included and randomized in two groups. While the first group used the CBITP, the control group received written instructions. Before and after taking part in the training program and 3 weeks later, the participants filled in a questionnaire for celiac knowledge. The results show that both intervention and control groups increased knowledge about CD. However, the intervention group showed significantly better outcome. A CBITP significantly increases knowledge and sustainability as compared to a conventional training for CD patients. CBITPs can enhance patients' training and treatment.

Abstract
Coeliac disease (CD) is caused by a complex immunological response provoked by grain protein in susceptible people. The majority of people with CD are symptom-free adults; the remainder are prone to a bewildering variety of signs and symptoms, ranging from infertility to type 1 diabetes. Many patients with undiagnosed CD spend years seeking help for complaints such as chronic tiredness or mild abdominal symptoms. In primary care, an appropriate target group to test for CD is people with anaemia (especially women), chronic tiredness, non-specific abdominal symptoms (including so-called "irritable bowel syndrome"), or a family history of CD. The response to an appropriate gluten-free diet is often life-transforming for symptomatic patients. Positive serological tests for CD require confirmation by duodenal biopsy and, if confirmed, referral to a dietitian and a coeliac society, followed by a life-long gluten-free diet.

Abstract
BACKGROUND AND AIMS It has been reported that occult gastrointestinal bleeding as detected by faecal occult blood (FOB) testing can occur in coeliac disease. This study examines whether a positive FOB is a feature of coeliac disease and whether FOB-positive subjects need investigation for coeliac disease. METHODS First, the records of patients on the Nottingham Register for Coeliac Disease were reviewed for positive FOB testing. Second, the Nottingham colorectal cancer screening trial database was also reviewed to examine how many coeliac patients on the Register had participated and to examine their FOB results. Finally, sera from 309 screening trial participants who were FOB-positive but had no colonic abnormality were screened for immunoglobulin A (IgA) gliadin and IgA endomysial and human tissue transglutaminase (tTG) IgA antibodies. RESULTS Five of 590 patients on the Register had had FOB tests at the time of diagnosis; four had positive tests during investigation of diarrhoea and/or anaemia. Of 21 patients on the Register who had participated in the colorectal cancer screening trial, one had a positive FOB test and was found to have a rectal tubulo-villous adenoma. Of the 309 FOB-positive patients, 7% (22 subjects) were positive for IgA gliadin antibodies, but none had IgA endomysial antibodies detected and two subjects had positive human tTG antibody assays for coeliac disease. CONCLUSIONS Occult gastrointestinal bleeding occurs in a small number of symptomatic coeliac disease patients before diagnosis, but is no more frequent in treated and undetected coeliac disease patients than in the general population. Unless there are other indications, coeliac disease does not need to be considered in the investigation of a positive FOB test.

Abstract
Women with long-standing coeliac disease express poorer health-related quality of life (HRQoL) than men do for unclear reasons. This led us to explore differences in their understanding of HRQoL using a phenomenographic approach. We interviewed 10 coeliac subjects (mean age 57 years, range 35-73) who had been on a gluten-free diet for 10 years and had scored either high or low in the Short Form 36 Health Survey (SF-36) General Health and Vitality scales. Three dimensions were revealed that pertained to their perception of HRQoL: bodily sensations, social consequences and coping strategies. Within these, the women experienced more bowel symptoms than men did, despite keeping to a strict diet. This item was the only one predicting the SF-36 scores. The women also described more distress caused by the restrictions in daily life, closely related to their controlling of food contents. The coeliac men took advantage of using a problem-oriented coping approach while the women seeking an emotionally oriented strategy showed less satisfaction with the outcome. We conclude that the intriguing difference in HRQoL between coeliac men and women may have some of its origin in the way living with the disorder is conceptualized and coped with. The results imply that in the management of coeliac patients, gender-related aspects need to be taken into account to improve treatment outcome.

Abstract
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.

Abstract
AIMS To determine the prevalence of coeliac disease in a group of patients in the community who have been shown in the laboratory to have iron and/or folate deficiency. To assess the cost efficiency of this laboratory based case finding strategy. METHODS The study was undertaken in a large general hospital in the UK serving a population of 300 000. Three hundred and thirty three eligible patients with iron and/or folate deficiency were identified and contacted over an 18 month period. Case finding was by testing for coeliac disease using serological methods and subsequent histological confirmation. RESULTS Of the 333 eligible and contactable patients with iron and/or folate deficiency, 258 (77%) consented to coeliac disease antibody testing. Twenty eight patients (10.9%) were positive for coeliac disease antibodies. Of these, 24 patients proceeded to endoscopy and biopsy, resulting in 12 cases of histologically confirmed coeliac disease (4.7% (95% confidence interval, 2.1% to 6.8%) of patients tested for coeliac disease antibodies). CONCLUSIONS This laboratory based methodology detected a considerable number of new coeliac disease cases in the community. Many of these patients did not present with clinical findings suggestive of malabsorption and might not otherwise have been diagnosed. Laboratory based methodologies should be considered in conjunction with other strategies for the early identification and treatment of coeliac disease.

Abstract
Both celiac disease and inflammatory bowel disease (IBD) are characterized by chronic diarrhea and the presence of distinct (auto)antibodies. In the present study we wanted to determine the prevalence of serological markers for inflammatory bowel disease, i.e., perinuclear antineutrophil cytoplasmic antibodies (pANCA) and/or anti-Saccharomyces cerevisiae antibodies (ASCA), in 37 patients with biopsy-confirmed celiac disease (Marsh IIIb/c). The majority of the patients was positive for IgA (auto)antibodies typically associated with celiac disease, i.e., antiendomysium antibodies (EMA) (86.5%), antigliadin antibodies (AGA) (73%), and antirecombinant human tissue transglutaminase antibodies (rh-tTGA) (86.5%). Four patients with selective IgA deficiency could be identified by analyzing EMA, AGA, and rh-tTGA for the IgG isotype. The prevalence of pANCA and ASCA, markers that are used for IBD, was unexpectedly high in our cohort of patients with celiac disease: 8 patients were positive for pANCA (IgG) and 16 patients were positive for ASCA (IgG and/or IgA). These results indicate that the presence of pANCA or ASCA in the serum of patients with chronic diarrhea does not exclude celiac disease. A prospective study is required to determine whether pANCA and/or ASCA identify patients at risk for developing secondary autoimmune disease.

Abstract
BACKGROUND Patients with coeliac disease are advised to keep to a lifelong gluten-free diet to remain well. Uncertainty still exists as to whether this gives a nutritionally balanced diet. AIM To assess the vitamin nutrition status of a series of coeliac patients living on a gluten-free diet for 10 years. METHODS Thirty adults with coeliac disease (mean age, 55 years; range, 45-64 years; 60% women), in biopsy-proven remission following 8-12 years of dietary treatment, were studied. We measured the total plasma homocysteine level, a metabolic marker of folate, vitamin B-6 and vitamin B-12 deficiency, and related plasma vitamin levels. The daily vitamin intake level was assessed using a 4-day food record. Normative data were obtained from the general population of the same age. RESULTS Coeliac patients showed a higher total plasma homocysteine level than the general population, indicative of a poor vitamin status. In accordance, the plasma levels of folate and pyridoxal 5'-phosphate (active form of vitamin B-6) were low in 37% and 20%, respectively, and accounted for 33% of the variation of the total plasma homocysteine level (P < 0.008). The mean daily intakes of folate and vitamin B-12, but not of vitamin B-6, were significantly lower in coeliac patients than in controls. CONCLUSIONS Half of the adult coeliac patients carefully treated with a gluten-free diet for several years showed signs of a poor vitamin status. This may have clinical implications considering the linkage between vitamin deficiency, elevated total plasma homocysteine levels and cardiovascular disease. The results may suggest that, when following up adults with coeliac disease, the vitamin status should be reviewed.

Abstract
The face of celiac disease has changed significantly over the past 50 years. With the advent of new noninvasive and more sensitive screening tools, it has become increasingly apparent that this disease presents in a heterogeneous fashion, with symptomatic disease only occurring in a small number of patients. Furthermore, great insights have been made into the disease's genetic and immunological components, thus increasing the medical community's understanding of the disease. The current gold standard for diagnosis is histological confirmation, and the cornerstone of therapy is lifelong elimination of gluten. Further advances in immunobiological techniques will most likely aid in earlier detection and commencement of the appropriate diet, thus preventing the development of associated complications.

Abstract
OBJECTIVES The aims of the study were to quantify the prevalence of asymptomatic coeliac disease (CD) in a cohort of osteoporotic females, and to investigate the features of bone loss. DESIGN AND SUBJECTS We studied 255 women (mean age 66.6 +/- 8.5 SD) with primary osteoporosis (WHO diagnostic criteria). After the first CD screening with the measure of serum IgG antigliadin antibodies (IgG-AGA), 53 women showed a positive test: antibodies to tissue transglutaminase (TG-ab) were subsequently determined to confirm the diagnosis of CD. Bone metabolism was evaluated by: serum and urinary calcium, serum and urinary phosphate, serum alkaline phosphatase, urinary crosslaps, serum 25(OH)D and serum parathyroid hormone. RESULTS High levels of IgG-AGA and TG-ab were observed in 24 patients with a prevalence of serological disease of 9.4%. These women were characterized, in comparison with the other patients, by a statistically significant reduction in serum 25(OH)D (17.8 +/- 7.2 vs. 55.1 +/- 20.3 nmol L(-1), P < 0.01) together with a significant increase of iPTH (65.1 +/- 29.7 vs. 35.1 +/- 20.0 pg mL(-1); P < 0.01). Patients with high TG-ab levels showed also slightly raised values of urinary crosslaps (288 +/- 88 vs. 270 +/- 90 microm mol(-1) Cr). In IgG-AG positive patients a statistically significant inverse correlation was found between 25(OH)D serum levels and log-transformed TG-ab values (r: -0.95, P < 0.001). Intestinal biopsies were obtained in 10 TG-ab positive women and verified CD in six patients. CONCLUSIONS These data support the hypothesis that patients with undiagnosed celiac disease develop high remodelling processes related to calcium malabsorption, secondary hyperparathyroidism and unavailability of vitamin D with a consequent more marked bone loss.

Abstract
Celiac disease is more prevalent than it was previously thought to be, and screening of selected population groups may reveal many new cases. Tissue transglutaminase appears to have a significant role in the degradation of gliadin and antigen production. Specific gliadin epitopes have been defined using T-cell responses. Bone disease is a significant problem for patients with celiac disease but management guidelines are being developed. Refractory sprue (nonresponsive celiac disease) appears to be a manifestation of enteropathy-associated T-cell lymphoma in most cases.

Abstract
AIM To update previous overviews of placebo-controlled double-blind trials assessing the efficacy and tolerance of smooth muscle relaxants in irritable bowel syndrome. METHODS AND TRIALS: A total of 23 randomized clinical trials were selected for meta-analyses of their efficacy and tolerance. Six drugs were analysed: cimetropium bromide (five trials), hyoscine butyl bromide (three trials), mebeverine (five trials), otilium bromide (four trials), pinaverium bromide (two trials) and trimebutine (four trials). The total number of patients included was 1888, of which 945 received an active drug and 943 a placebo. RESULTS The mean percentage of patients with global improvement was 38% in the placebo group (n=925) and 56% in the myorelaxant group (n=927), in favour of myorelaxants with a mean odds ratio of 2.13, P < 0.001 (95% CI: 1.77--2.58) and a mean risk difference of 22% P < 0.001 (95% CI: 13--32%). The percentage of patients with pain improvement was 41% in the placebo group (n=568) and 53% in the myorelaxant group (n=567): odds ratio 1.65, P < 0.001 (95% CI: 1.30--2.10) and risk difference 18%, P < 0.001 (95% CI: 7--28%). There was no significant difference for adverse events. CONCLUSION Myorelaxants are superior to placebo in the management of irritable bowel syndrome.

Abstract
Plaques of psoriasis contain increased levels of cytokines, including tumour necrosis factor-alpha (TNF-alpha), which are thought to be essential to the maintenance of the psoriatic process. We report the successful treatment of severe, recalcitrant psoriasis when infliximab (a monoclonal antibody to TNF-alpha) was used in combination with methotrexate.

Abstract
OBJECTIVE Iron deficiency anemia has been reported as the most frequent extraintestinal symptom in adult celiac disease. Prospective studies on the effect of gluten-free diet on recovery from iron deficiency anemia are lacking. The aim of this study was to verify in adult patients with celiac disease the efficacy of and the time course of recovery from iron deficiency anemia by a gluten-free diet alone. METHODS We studied 190 consecutive adult patients with iron deficiency anemia, screened for celiac disease by duodenal biopsies. New diagnosed celiac patients were invited to follow a gluten-free diet alone without iron supplementation. After 6 months of diet, duodenal biopsies were performed and hematological tests were repeated at 6, 12, and 24 months. RESULTS Celiac disease was diagnosed in 26 (24 women, 2 men; 13.7%) adult patients. After 6 months of gluten-free diet 14 of 18 (77.8%) female patients recovered from anemia, but only 5 of 18 (27.8%) reversed from iron deficiency. At 12-month control all but one patient (94.4%) recovered from anemia and 9 patients (50%) from iron deficiency. After 24 months of diet, only the patient who did not recover from anemia at 12-month control was still anemic, whereas 10 patients (55.5%) reversed from iron deficiency. A significant inverse correlation (r = -0.7141, p = 0.0003) between increase of Hb concentrations and decrease of individual histological scores of duodenitis was observed. CONCLUSIONS A screening for celiac disease should be carried out in adult patients with iron deficiency anemia. Recovery from anemia occurs between 6 and 12 months on a gluten-free diet alone as a consequence of normalization of histological alterations of the intestinal mucosa.

Abstract
Acute diarrhoea continues to carry a high morbidity and mortality worldwide. Intestinal infection is the major cause of acute diarrhoea although the prevalence of individual pathogens varies according to geographic location. In many countries in the industrialized world, reports of intestinal infections continue to increase; these are largely related to waterborne and foodborne outbreaks. Acute diarrhoea may be due to increased intestinal secretion, commonly as a result of infection with enterotoxin-producing organisms (enterotoxigenic Escherichia coli, Vibrio cholerae) or to decreased intestinal absorption from infection with organisms that damage the intestinal epithelium (enteropathogenic E. coli, Shigella sp., Salmonella sp.). Although oral rehydration therapy has reduced the mortality associated with acute diarrhoea, the diarrhoea attack rate remains unchanged and stool volume often increases during the rehydration process. The search for agents that will directly inhibit intestinal secretory mechanisms and thereby reduce stool volume has been going on for more than 20 years. Research during the past decade has highlighted the importance of neurohumoral mechanisms in the pathogenesis of diarrhoea, notably the role of 5-hydroxytryptamine, substance P, vasoactive intestinal polypeptide and neural reflexes within the enteric nervous system. Cholera toxin, E. coli enterotoxins and Clostridium difficile toxin A are known to invoke these mechanisms in diarrhoea pathogenesis. This new dimension of intestinal pathophysiology has already exposed possible novel targets for anti-secretory therapy, namely, 5-HT receptor antagonists, substance P antagonists and the possibility for potentiating the proabsorptive effects of endogenous enkephalins by use of enkephalinase inhibitors. There now seems to be a real possibility that anti-secretory therapy will become more widely available in the future.

Abstract
OBJECTIVE The aim of this study was to investigate the role of genetic factors and the characteristics of five monozygous twin pairs with at least one member affected by gluten sensitivity. METHODS Five pairs of monozygous female twins, of whom one or both were affected by gluten sensitivity (i.e., celiac disease or dermatitis herpetiformis), were followed-up for 11-23 yr. RESULTS Three pairs were concordant for celiac disease: the onset was comparable and synchronous in two pairs; in the third, one member presented an overt malabsorption syndrome, and the other developed iron deficiency anemia 10 yr later. Discordance for gluten sensitivity was found in the remaining two pairs, one of whose members was diagnosed as having, respectively, celiac disease and dermatitis herpetiformis. CONCLUSIONS As no environmental factors were found to affect the phenotypic expression of the disease, genetic factors seem to play a major role. The presence of overt or latent celiac disease in three of the four siblings of the three concordant twins, and the association with cystic fibrosis in all three siblings of one of these families, further supports this hypothesis.
