Background: Non-celiac wheat sensitivity (NCWS) is a poorly understood gluten-related disorder (GRD) and its prominent symptoms can be ameliorated by gluten avoidance. This study aimed to determine the effectiveness of a probiotic mixture in hydrolyzing gliadin peptides (toxic components of gluten) and suppressing gliadin-induced inflammatory responses in Caco-2 cells. Methods: Wheat dough was fermented with a probiotic mix for 0, 2, 4, and 6 h. The effect of the probiotic mix on gliadin degradation was monitored by SDS-PAGE. The expression levels of IL-6, IL-17A, INF-γ, IL-10, and TGF-β were evaluated using ELISA and qRT-PCR methods. Results: According to our findings, fermenting wheat dough with a mix of B. longum, L. acidophilus, and L. plantarum for 6 h was effective in gliadin degradation. This process also reduced levels of IL-6 (p = 0.004), IL-17A (p = 0.004), and IFN-γ (p = 0.01) mRNA, as well as decreased IL-6 (p = 0.006) and IFN-γ (p = 0.0009) protein secretion. 4 h fermentation led to a significant decrease in IL-17A (p = 0.001) and IFN-γ (p = 0.003) mRNA, as well as reduced levels of IL-6 (p = 0.002) and IFN-γ (p < 0.0001) protein secretion. This process was also observed to increase the expression levels of IL-10 (p < 0.0001) and TGF-β (p < 0.0001) mRNA. Conclusions: 4 h fermentation of wheat flour with the proposed probiotic mix might be a good strategy to develop an affordable gluten-free wheat dough for NCWS and probably other GRD patients.

Background: Celiac disease (CD) is still underestimated. To close this diagnostic gap, the Health Sicilian Authorities have constituted the "Sicilian Network for CD". Aims: A) To verify the quality of the current diagnostic approach using the data sheet of the Network. B) To evaluate the clinical, serologic and histologic data of new diagnoses in the context of the Network METHODS: We retrospectively evaluated the data collection forms of 369 patients with CD from three Centers within the Sicilian Network. All the Centers used a standard data collection form. Results: A non-classical CD presentation was more frequent than the classical one, anemia being the most frequent symptom (50%). An IBS-like presentation was found in one third of the cases. A diagnostic delay of about 9 years following the onset of symptoms was observed. Almost half of the patients had not undergone multiple duodenal biopsies; unrecommended CD serology assays were prescribed in 59.9% of the cases. Conclusions: The regional data sheets allowed an assessment of the diagnostic delay. We recorded a frequent use of unrecommended tests prescribed before referring patients to the regional Centers. Updating the education of physicians regarding CD is necessary to avoid unwarranted health expenditure.

Le ulcere/lesioni da pressione hanno una genesi multifattoriale e possono essere causa di svariate complicanze. Un aspetto troppo spesso dimenticato è il loro costo per il Sistema Sanitario Nazionale (SSN). I casi di due pazienti ricoverate presso il reparto di Geriatria e Lungodegenza dell’Azienda Ospedaliera Universitaria “Paolo Giaccone” di Palermo sono in proposito emblematici

There are few data regarding the diagnostic delay and its predisposing factors in coeliac disease (CD).To investigate the overall, the patient-dependant, and the physician-dependant diagnostic delays in CD.CD adult patients were retrospectively enroled at 19 Italian CD outpatient clinics (2011-2021). Overall, patient-dependant, and physician-dependant diagnostic delays were assessed. Extreme diagnostic, i.e., lying above the third quartile of our population, was also analysed. Multivariable regression models for factors affecting the delay were fitted.Overall, 2362 CD patients (median age at diagnosis 38 years, IQR 27-46; M:F ratio=1:3) were included. The median overall diagnostic delay was 8 months (IQR 5-14), while patient- and physician-dependant delays were 3 (IQR 2-6) and 4 (IQR 2-6) months, respectively. Previous misdiagnosis was associated with greater physician-dependant (1.076, p = 0.005) and overall (0.659, p = 0.001) diagnostic delays. Neurological symptoms (odds ratio 2.311, p = 0.005) and a previous misdiagnosis (coefficient 9.807, p = 0.000) were associated with a greater extreme physician-dependant delay. Gastrointestinal symptoms (OR 1.880, p = 0.004), neurological symptoms (OR 2.313, p = 0.042), and previous misdiagnosis (OR 4.265, p = 0.000) were associated with increased extreme overall diagnostic delay.We identified some factors that hamper CD diagnosis. A proper screening strategy for CD should be implemented.

Background: Patients suffering from non-celiac wheat sensitivity (NCWS) frequently report extra- intestinal symptoms, such as anemia. Aims: We investigated the prevalence and associated clinical features of anemia in NCWS patients. Methods: Data from 244 NCWS patients, diagnosed by double-blind placebo-controlled wheat challenge, were retrospectively reviewed and compared with 2 control groups (celiac disease (CD) and irritable bowel syndrome (IBS)). Furthermore, 31 NCWS anemic patients were prospectively re-evaluated after at least 12 months on the “strict”wheat-free diet (WFD). Results: Anemia prevalence in NCWS patients was 34.8% (mean hemoglobin 10.4 ±1.4 g/dl), significantly higher than in IBS (17.4%, P = 0.03), but not in CD ones. The NCWS group, on the whole, had sideropenic- like features with low serum iron and altered iron deposits. Both anemia prevalence and sideropenic-like features were more evident in CD than in NCWS patients, whereas only a few IBS subjects showed such features. Significant differences were found in anemic vs non-anemic NCWS patients as regards to female sex, diagnostic delay, poly/hypermenorrhea, iron deficiency, and higher TSH values. A long-term WFD significantly reduced anemia and improved iron metabolism. Conclusion: Microcytic/hypochromic anemia and altered iron metabolism occur frequently in NCWS and can be treated with a long-term strict WFD. NCWS should be included in differential diagnosis of anemic patients with “functional gastrointestinal troubles”.

Objective: 'Self-reported wheat sensitivity' (SRWS) is a self-reported condition caused by wheat ingestion in the absence of celiac disease or wheat allergy. The aim of the study was to investigate the frequency and characteristics of SRWS in outpatients referred for digestive endoscopy. Methods: The study, performed at the University of Palermo, enrolled 496 outpatients. Results: Seven individuals (1.4%) had an already established diagnosis of celiac disease. The questionnaire was administered to the other 489 individuals: 98 subjects (20%) were SRWS, the remaining 391 served as controls (i.e. not-SRWS). SRWS patients were younger (P

Introduction: Celiac disease (CD) is an immune-mediated disorder associated with gluten exposure in genetically predisposed subjects. Areas covered: Infectious disease is one of the causes of morbidity and mortality in CD patients. Invasive streptococcus pneumoniae (pneumococcus) is a particularly dangerous morbid condition in both the general population and celiac patients. Pneumococcal vaccination is the most effective means for its prevention. Expert opinion: In CD, evaluation of spleen function should be useful to select patients who may benefit from vaccination to reduce the risk of pneumococcal disease. Different strategies could be employed: physicians could search for signs of hyposplenism on peripheral blood smear or abdominal ultrasound. However, the best strategy to identify which patients will benefit from pneumococcal vaccination has not yet been defined.

A significant percentage of the general population reports gastrointestinal and non-gastrointestinal symptoms caused by wheat and/or gluten ingestion, even though they do not suffer from celiac disease (CD) or wheat allergy (WS), because they test negative both for CD-specific serology and histopathology. All patients report improvement of symptoms on a gluten-free diet. This clinical condition has been named non-celiac gluten sensitivity (NCGS). The objective of this paper was to review some studies regarding the pathogenesis of NCGS to summarize the current hypotheses about the mechanisms, which can lead to NCGS. Particular attention was given to the immunologic and the malabsorptive hypotheses. We reviewed data of our previous studies involving patients diagnosed with NCWS by means of double-blind placebo-controlled wheat challenge. The data indicating a possible wheat allergy diagnosis were examined and other data in the literature were reviewed; we also reviewed the putative role of fermentable oligosaccharides disaccharides monosaccharides and polyols (FODMAPs) and of α-amylasetrypsin inhibitors (ATIs) proteins in the NCGS pathogenesis. NCGS pathogenesis has been attributed to very different mechanisms, among others: i) activation of innate and adaptive immunity (the immune/allergic mechanisms) induced by gluten or the non-gluten ATI family; ii) incomplete digestion and/or absorption of FODMAPs (the intolerance mechanisms); and iii) psychological effect.We suggest that NCGS is a heterogeneous condition, which includes different subgroups of patients who have different pathogenic mechanisms: strong data suggest a direct pathogenic immunogenic/inflammatory role of wheat-cereal proteins (not only gluten) in a subgroup, probably the largest, of these patients.

BACKGROUND We recently demonstrated that the odds of contracting coronavirus disease 2019 (COVID-19) in patients with celiac disease (CeD) is similar to that of the general population. However, how patients with CeD perceive their COVID-19 risk may differ from their actual risk. AIM To investigate risk perceptions of contracting COVID-19 in patients with CeD and determine the factors that may influence their perception. METHODS We distributed a survey throughout 10 countries between March and June 2020 and collected data on demographics, diet, COVID-19 testing, and risk perceptions of COVID-19 in patients with CeD. Participants were recruited through various celiac associations, clinic visits, and social media. Risk perception was assessed by asking individuals whether they believe patients with CeD are at an increased risk of contracting COVID-19 when compared to the general population. Logistic regression was used to determine the influencing factors associated with COVID-19 risk perception, such as age, sex, adherence to a gluten-free diet (GFD), and comorbidities such as cardiac conditions, respiratory conditions, and diabetes. Data was presented as adjusted odds ratios (aORs) RESULTS A total of 10737 participants with CeD completed the survey. From them, 6019 (56.1%) patients with CeD perceived they were at a higher risk or were unsure if they were at a higher risk of contracting COVID-19 compared to the non-CeD population. A greater proportion of patients with CeD perceived an increased risk of contracting COVID-19 when compared to infections in general due to their CeD (56.1% vs 26.7%, P < 0.0001). Consequently, 34.8% reported taking extra COVID-19 precautions as a result of their CeD. Members of celiac associations were less likely to perceive an increased risk of COVID-19 when compared to non-members (49.5% vs 57.4%, P < 0.0001). Older age (aOR: 0.99; 95%CI: 0.99 to 0.99, P < 0.001), male sex (aOR: 0.84; 95%CI: 0.76 to 0.93, P = 0.001), and strict adherence to a GFD (aOR: 0.89; 95%CI: 0.82 to 0.96, P = 0.007) were associated with a lower perception of COVID-19 risk and the presence of comorbidities was associated with a higher perception of COVID-19 risk (aOR: 1.38; 95%CI: 1.22 to 1.54, P < 0.001). CONCLUSION Overall, high levels of risk perceptions, such as those found in patients with CeD, may increase an individual's pandemic-related stress and contribute to negative mental health consequences. Therefore, it is encouraged that public health officials maintain consistent communication with the public and healthcare providers with the celiac community. Future studies specifically evaluating mental health in CeD could help determine the consequences of increased risk perceptions in this population.

Background: Non-Celiac Wheat Sensitivity (NCWS) is characterized by both intestinal and extra-intestinal symptoms. The study aims to investigate the frequency of neuropsychiatric manifestations in NCWS patients and identify their clinical and demographic characteristics. Methods: 278 clinical records of NCWS patients, diagnosed by a double-blind placebo-controlled wheat challenge between 2006 and 2020, were retrospectively revised. Fifty-two patients with Celiac Disease (CD) and 54 patients with Irritable Bowel Syndrome (IBS) served as controls. Results: 87% of the NCWS patients had an IBS-like clinical presentation. The NCWS group showed a longer duration of symptoms, a higher frequency of positive serum anti-nuclear antibodies than CD and IBS patients, and a higher frequency of DQ2/DQ8 haplotypes and duodenal mucosa lymphocytosis than IBS controls. In addition, 50% of NCWS patients showed neuropsychiatric manifestations, while lower percentages were observed in CD (25%) and IBS (28%) controls. Neuropsychiatric symptoms in NCWS were more frequently associated with the male sex, longer duration of symptoms, and IBS-diarrhea-like clinical presentation. Conclusions: Our data suggest that in patients with IBS-like symptoms and neuropsychiatric manifestations of unknown cause, it could be useful to investigate a correlation of these symptoms with wheat ingestion to identify NCWS patients with this ‘atypical’ manifestation.

The World Health Organization declared coronavirus disease-2019 (COVID-19) a global pandemic in March 2020. Since then, there are more than 34 million cases of COVID-19 leading to more than 1 million deaths worldwide. Numerous studies suggest that celiac disease (CeD), a chronic immune-mediated gastrointestinal condition triggered by gluten, is associated with an increased risk of respiratory infections.(1-3) However, how it relates to the risk of COVID-19 is unknown. To address this gap, we conducted a cross-sectional study to evaluate whether patients with self-reported CeD are at an increased risk of contracting COVID-19.

Background & Aims Ancient wheat varieties are considered to be healthier than modern ones, but the data are not univocal. We investigated changes in hematochemical parameters and evaluated microbiota data before and after a set period on a diet containing a whole-meal ancient wheat mix. Patients and Methods 29 cloistered nuns were recruited. The study comprised two consecutive 30-day periods; during the first one (T1), the nuns received wheat-based foods produced with refined “modern” flour (“Simeto”); during the second one (T2) received wheat-based foods produced with an unrefined flour mix composed of “ancient” cultivars. At entry to the study (T0) and at the end of T1 and T2 hematochemical parameters and fecal microbiota and metabolome were evaluated. Results At the end of T2, there was a significant reduction in serum iron, ferritin, creatinine, sodium, potassium, magnesium, total cholesterol, LDL- and HDL-cholesterol and folic acid. Furthermore, increased the abundance of cultivable enterococci, lactic acid bacteria and total anaerobes. The ability of the gut microbiome to metabolize carbohydrates increased after the period of diet containing ancient grain products. Several volatile organic compounds increased after the one month on the diet enriched with ancient grain products. Conclusions Our data showed the beneficial effects deriving from a diet including ancient whole-meal/unrefined wheat flours.

In recent years, a new gluten- or wheat-related disease has emerged, a condition labeled "nonceliac gluten sensitivity" (NCGS) or "nonceliac wheat sensitivity" (NCWS). NCWS pathogenesis is still uncertain and attributed to very different mechanisms. We aimed to study the different T-lymphocyte subsets in the rectal mucosa of NCWS patients to demonstrate the possible contribution of adaptative immune response. Twelve patients (11 women, 1 man, age range 23-61 yr, median 32 yr) with a definitive diagnosis of NCWS were recruited at random for the present study. They underwent rectal endoscopy with multiple mucosal biopsies at the end of a double-blind placebo-controlled (DBPC) wheat challenge when they reported the reappearance of the symptoms. As controls we included 11 "healthy patients", sex- and age-matched with the patients who underwent colonoscopy evaluation for rectal bleeding due to hemorrhoids. Cells freshly obtained from rectal tissue were stained to detect anti-CD45, anti-CD3, anti-CD4, and anti-CD8. Furthermore, intracellular staining was performed with anti-tumor necrosis factor (TNF)-α, anti-interleukin (IL)-17, and anti-IL-22. Production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells, as well as of IL-17 by CD4+ cells, was higher in the rectal tissue of NCWS patients than in controls. On the contrary, IL-22 production by CD8+ cells was lower in NCWS patients than in the controls. In NCWS patients diagnosed by DBPC wheat challenge, there is a complex immunological activation, with a significant role for the adaptive response.NEW & NOTEWORTHY Nonceliac wheat sensitivity (NCWS) is a syndrome characterized by symptoms triggered by gluten intake. The pathogenesis is still uncertain. Studies have shown a role for innate immunity. We demonstrated that production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells and of IL-17 by CD4+ cells is higher in the rectal tissue of NCWS patients than in controls. We clearly demonstrated that in patients with NCWS there is a significant role for the adaptive response.

INTRODUCTION: Nonceliac wheat sensitivity (NCWS) is characterized by intestinal and extraintestinal manifestations consequent to wheat ingestion in subjects without celiac disease and wheat allergy. Few studies investigated the relationship between NCWS and autoimmunity. The aim of this study is to evaluate the frequency of autoimmune diseases (ADs) and autoantibodies in patients with NCWS. METHODS: Ninety-one patients (13 men and 78 women; mean age of 40.9 years) with NCWS, recruited in a single center, were included. Seventy-six healthy blood donors (HBD) and 55 patients with a diagnosis of irritable bowel syndrome (IBS) unrelated to NCWS served as controls. Autoantibodies levels were measured. Human leukocyte antigen haplotypes were determined, and duodenal histology performed in all patients carrying the DQ2/DQ8 haplotypes. Participants completed a questionnaire, and their medical records were reviewed to identify those with ADs. RESULTS: Twenty-three patients with NCWS (25.3%) presented with ADs; autoimmune thyroiditis (16 patients, 17.6%) was the most frequent. The frequency of ADs was higher in patients with NCWS than in HBD (P 5 0.002) and in patients with IBS (P 5 0.05). In the NCWS group, antinuclear antibodies tested positive in 71.4%vsHBD19.7%, and vs patients with IBS 21.8% (P < 0.0001 for both). The frequency of extractable nuclear antigen antibody (ENA) positivity was significantly higher in patients with NCWS (21.9%) than in HBD (0%) and patients with IBS (3.6%) (P 5 0.0001 and P 5 0.004, respectively). Among the patients with NCWS, 9.9% tested positive for antithyroglobulin, 16.5% for antithyroid peroxidase, and 14.3% for antiparietal cell antibodies; frequencies were not statistically different from controls. The presence of ADs was related to older age at NCWS diagnosis, female sex, duodenal lymphocytosis, and eosinophil infiltration. DISCUSSION: One in 4 patients withNCWS suffered from AD, and serum antinuclear antibodies were positive in a very high percentage of cases. These data led us to consider NCWS to be associated to ADs.

Minimal lesions of the small bowel are mucosal changes characterized by an increased number of intraepithelial lymphocytes (with or without crypt hyperplasia) and normal villous architecture. Such changes are associated with a wide spectrum of conditions, ranging from food intolerances to infections, and from drugs to immune diseases, with different clinical profiles and manifestations, which complicates the formulation of a differential diagnosis. Patient history, symptom evaluation, and histopathology are the diagnostic features needed to establish a correct diagnosis. Physicians should assist pathologists in formulating a precise morphological evaluation by taking well-oriented small intestinal biopsies and collecting informative clinical findings that inform histopathology. In this current clinical controversy, the authors provide the reader with an appraisal of the small intestine minimal lesions through a careful analysis of the major conditions (e.g., celiac disease and other non-celiac disorders) responsible for such changes and their differential diagnosis. Also, we acknowledge that some of the diseases detailed in this article may progress from an early minimal lesion to overt mucosal atrophy. Thus, the timing of the diagnosis is of paramount importance.

Background: Non-celiac wheat sensitivity (NCWS) most frequently presents clinically with irritable bowel syndrome (IBS)-like symptoms, although many extra-intestinal manifestations have also been attributed to it. No studies to date have evaluated the presence and frequency of gynecological symptoms in NCWS. Aim: To evaluate the frequency of gynecological disorders in patients with NCWS. Patients and Methods: Sixty-eight women with NCWS were included in the study. A questionnaire investigating gynecological symptoms and recurrent cystitis was administered, and patients reporting symptoms were then examined by specialists. Three control groups were selected: 52 patients with IBS not related to NCWS, 56 patients with celiac disease (CD), and 71 healthy controls. Results: 59% of the patients with NCWS showed gynecological symptoms, a higher frequency than in healthy controls (P = 0.04), IBS controls (P = 0.01) and CD controls (P = 0.02). Menstrual cycle alterations were more frequent in patients with NCWS than in healthy controls (26.5% vs 11.3%; P = 0.03); the patients with NCWS suffered from recurrent vaginitis (16%) and dyspareunia (6%) significantly more frequently than healthy controls. Twenty-nine percent of patients with NCWS reported recurrent cystitis, a finding higher than in the control groups (vs healthy P = 0.0001, vs IBS P = 0.001, vs CD controls P = 0.04). Microbiological examinations were negative in most of the patients with NCWS and recurrent vaginitis or cystitis. During the 1-year follow-up, 46% of patients with menstrual disorders and 36% with recurrent vaginitis reported resolution of symptoms on a wheat-free diet. Conclusions: Patients with NCWS showed a significantly higher frequency of gynecological symptoms and recurrent cystitis than patients with IBS.

Background: Lactose intolerance is the most frequent food intolerance, but many subjects with self-reported milk intolerance (SRMI) are asymptomatic at lactose hydrogen breath test (LHBT). The aim of this study was to evaluate the frequency of lactose intolerance in SRMI patients and their clinical characteristics. Methods: In a retrospective study, the clinical records of 314 SRMI patients (259 females, mean age: 39.1 ± 13.5 years) were reviewed; 102 patients with irritable bowel syndrome (IBS) served as controls. In a prospective study, 42 SRMI patients, negatives at the LHBT, underwent a double-blind, placebo-controlled (DBPC) whole cow’s milk challenge. Results: In the retrospective study, only 178 patients (56%) were lactose maldigesters and intolerant at LHBT; 68% of the subjects with SRMI were suffering from IBS; 74% reported dyspepsia (p = 0.0001 vs. IBS controls); and weight loss was recorded in 62 SRMI patients (20%) (p = 0.01 vs. IBS controls). Duodenal histology showed intra-epithelial lymphocytosis in about 60% of cases. In the prospective study, 36 patients (86%) experienced symptoms during the DBPC cow’s milk challenge, and only 4 patients (9%) reacted to placebo (p = 0.0001). Conclusions: A percentage of SRMI patients were not suffering from lactose intolerance. DBPC revealed that SRMI patients had clinical reactions when exposed to whole cow’s milk.

Few studies have investigated the influence of age on the relationships between systemic vascular damage, kidney dysfunction, and intrarenal hemodynamic changes in patients with hypertension without overt cardiovascular disease. The authors enrolled 126 elderly patients with hypertension (aged ≥65 years) and 350 nonelderly patients with hypertension (aged

Background: Non-Celiac Wheat Sensitivity (NCWS) is still a largely undefined condition, due to the lack of a diagnostic marker. Few data are available about the nutritional characteristics of NCWS patients at diagnosis. Aims: To evaluate the proportion of NCWS patients who were underweight, normal weight, overweight, or obese at diagnosis, and to search for possible correlations between their Body Mass Index (BMI) and other NCWS-related disease characteristics. Patients and Methods: The clinical charts of 145 NCWS patients (125 F, 20 M, mean age 37.1 &plusmn, 11.4 years), diagnosed between January 2012 and March 2018, were reviewed. As a comparison, 84 celiac disease (CD) patients (73 F, 11 M, mean age 39.8 &plusmn, 13.9 years) were evaluated. All NCWS diagnoses were based on a double-blind placebo-controlled wheat challenge (DBPCWC) method. Results: BMI distribution was similar in the NCWS (6.2% underweight and 15.2% obese subjects) and CD patients (6% underweight and 7.1% obese subjects). Underweight NCWS subjects were significantly younger and had a shorter clinical history than the overweight or obese ones. Unlike the other NCWS patients, none of them had a DQ2 and/or DQ8 haplotype. Overweight and obese NCWS patients were more frequently suffering from associated autoimmune diseases than the other BMI categories (P = 0.05). Compared to the CD controls, NCWS patients showed a higher frequency of Irritable Bowel Syndrome (IBS)-like (P = 0.01) and extraintestinal symptoms (P = 0.03) and a longer clinical history (P = 0.04), whereas weight loss was more frequent in CD (P = 0.02). Conclusions: NCWS patients showed a BMI distribution similar to CD patients. However, NCWS was found to be a heterogenous condition that regards BMI, and clinical characteristics differed between the underweight and overweight/obese patients.

GOALS: The goal of this study was (A) to evaluate abdominal ultrasound signs in nonceliac wheat sensitivity (NCWS) patients for features useful in diagnosis and (B) to compare these aspects with those of celiac patients to assess whether ultrasound can be useful in the differential diagnosis between NCWS and celiac disease (CD). BACKGROUND: NCWS diagnosis is difficult as no biomarkers of this condition have as yet been identified. In CD ultrasound aspects have been identified that have a good diagnostic accuracy. STUDY: We prospectively recruited 45 NCWS patients (11 males, 34 females; mean age 35.7 y). Three control groups were included: (A) 99 age-matched CD patients; (B) 18 patients with seronegative CD; (C) 50 patients with irritable bowel syndrome (IBS) who did not improve on a wheat-free diet. NCWS diagnosis was confirmed on the basis of an elimination diet and double-blind placebo-controlled (DBPC) challenge. Ultrasound sign investigation included: dilatation of the small bowel loops, thickening of the small bowel wall, hyperperistalsis, enlarged mesenteric lymph nodes, ascites, hyposplenism, altered diameter of the portal vein. RESULTS: NCWS patients showed a low frequency of pathologic ultrasound findings. Dilated or thickened loops appeared more often in CD patients than in NCWS patients (88.8% vs. 20%; P

Anaemia is a common pathologic condition, present in almost 5% of the adult population. Iron deficiency is the most common cause; other mechanisms can be involved, making anaemia a multi-factorial disorder in most cases. Anaemia being a frequent manifestation in the diseases of the gastrointestinal tract, patients are often referred to gastroenterologists. Furthermore, upper and lower endoscopy and enteroscopy are pivotal to the diagnostic roadmap of anaemia. In spite of its relevance in the daily clinical practice, there is a limited number of gastroenterological guidelines dedicated to the diagnosis of anaemia. For this reason, the Italian Association of Hospital Gastroenterologists and Endoscopists and the Italian Society of Paediatric Gastroenterology, Hepatology and Nutrition commissioned a panel of experts to prepare a specific guideline on anaemia and its diagnostic roadmap in the gastroenterological scenario. The panel also discussed about the potential involvement of gastroenterologists and endoscopists in the management of patients with anaemia, with particular attention to the correct use of investigations. The panel paid particular attention to practical issues with the aim to support gastroenterologists in their clinical practice when dealing with patients with anaemia.

Mediterranean spotted fever (MSF) is an infectious disease endemic in the southern regions of Italy, with an incidence of about 400 cases/year. The bacteria responsible of the disease is Rickettsia conorii, transmitted to humans by Rhipicephalus sanguineus, the common dog tick. The infection usually manifests with a characteristic symptomatologic triad: fever, exanthema and the so called tache noire, which is the typical eschar at the site of the tick bite. Immunoglobulin M (IgM) and IgG enzymelinked immunosorbent assay and the gold standard micro-immunofluorescent assay, allow serological diagnosis. We report the case of a man suffering from MSF, whose atypical presentation and false-negative diagnostic tests delayed consistently diagnosis and therapy. Afterwards we review the literature about this topic.

Short bowel syndrome refers to the malabsorptive state caused by loss of significant portions of the small intestine, whose clinical framework is characterized by malnutrition, diarrhea, dehydration, weight loss, and low-weight-related symptoms/signs. These clinical conditions seem to be related to the length of resection. Twenty-one years ago we reported the clinical case of an infant, who underwent a massive resection of the loops of the small intestine, of the cecum and of part of the ascending colon, due to intestinal malrotation with volvulus. The residual small intestine measured just 11 cm and consisted of the duodenum and a small part of jejunum, in the absence of the ileocecal valve, configuring the case of a ultra-short bowel syndrome. In this report, we update the case, reporting the patient succeeded to obtain a good weight gain and to conduct a quite normal lifestyle, despite the long-term consequences of such resection.
