Abstract
BACKGROUND Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist recently approved for treating ulcerative colitis (UC) but with limited real-world data. Therefore, we evaluated the effectiveness and safety of UST in patients with UC in a real-world setting. RESEARCH DESIGN AND METHODS This is a multicenter, retrospective, observational cohort study. The primary endpoints were the clinical remission rate (partial Mayo score, PMS, ≤1) and the safety of UST. Other endpoints were corticosteroid-free remission (CSFR) rate, clinical response rate (PMS reduction of at least 2 points), and fecal calprotectin (FC) reduction at week 24. RESULTS We included 256 consecutive patients with UC (M/F 139/117, median age 52). The clinical remission and clinical response rates at eight weeks were 18.7% (44/235) and 53.2% (125/235), respectively, and 27.6% (42/152) and 61.8% (94/152) at 24 weeks, respectively. At 24 weeks, CSFR was 20.3% (31/152), and FC significantly dropped at week 12 (p = 0.0004) and 24 (p = 0.038). At eight weeks, patients naïve or with one previous biologic treatment showed higher remission (p = 0.002) and clinical >response rates (p = 0.018) than patients previously treated with ≥ 2. Adverse events occurred in six patients (2.3%), whereas four patients (1.6%) underwent colectomy. CONCLUSION This real-world study shows that UST effectively and safely treats patients with UC.

Abstract
The literature reports that there was a significant difference in the medical impact of the coronavirus disease (COVID-19) pandemic between European and East Asian countries; specifically, the mortality rate of COVID-19 in Europe was significantly higher than that in East Asia. Considering such a difference, our narrative review aimed to compare the prevalence and characteristics of residual lung abnormalities at one-year follow-up computed tomography (CT) after severe or critical COVID-19 in survivors of European and East Asian countries. A literature search was performed to identify articles focusing on the prevalence and characteristics of CT lung abnormalities in survivors of severe or critical COVID-19. Database analysis identified 16 research articles, 9 from Europe and 7 from East Asia (all from China). Our analysis found a higher prevalence of CT lung abnormalities in European than in Chinese studies (82% vs. 52%). While the most prevalent lung abnormalities in Chinese studies were ground-glass opacities (35%), the most prevalent lung abnormalities in European studies were linear (59%) and reticular opacities (55%), followed by bronchiectasis (46%). Although our findings required confirmation, the higher prevalence and severity of lung abnormalities in European than in Chinese survivors of COVID-19 may reflect a greater architectural distortion due to a more severe lung damage.

Abstract
Ferroelectric perovskite ceramics with a high dielectric constant, low loss, high tunability, and high electric breakdown are ideal for Nonlinear Transmission Lines (NLTLs) to generate radio frequency (RF) signals at high-power levels. To achieve the required properties, a comprehensive study of the material phase transitions and the optimal ratio adjustment between the chemical elements in the perovskite crystal structure are required. The advancement of this solid-state technology is the most promising optimization for NLTLs in developing high-power (>100 MW) devices with high tunability (>60%) and high repetition rate (>1 kHz) for soliton generation. The barium strontium zirconium titanate (BSZT) ceramic compositions were synthesized and characterized to maximize material tunability. The composition Ba0.97Sr0.03Zr0.2Ti0.8O3 exhibited a high permittivity (>12,200), low loss tangent (<0.01), and an exceptional tunability of the order of 79% at an electric field of 10 kV/mm near the phase temperature transition at 300 K. Ferroelectric ceramic is an outstanding material with promising characteristics for producing RF signals in an NLTL, and here, the BSZT is considered for this application.

Abstract
BACKGROUND Vedolizumab (VDZ) can be used to treat refractory ulcerative colitis (UC) and Crohn's disease (CD). We assessed whether there are differences in treating UC vs CD with VDZ. RESEARCH DESIGN AND METHODS Mayo score in UC and the Harvey-Bradshaw Index (HBI) in CD scored the clinical activity. Achievement and maintenance of clinical remission during the follow-up, and safety were the primary endpoints. RESULTS 729 patients (475 with UC and 254 with CD), median follow-up of 18 (IQR 6-36) months, were enrolled. Clinical remission at the 6th month of treatment was achieved in 488 (66.9%) patients (74.4% in CD vs 62.9% in UC, p<0.002) while, during the follow-up, no difference was found (81.5% in the UC group and 81.5% pts in the CD group; p=0.537). The clinical remission at the 6th month of treatment (p=0.001) and being naïve to biologics (p<0.0001) were significantly associated with prolonged clinical remission. The clinical response was significantly higher in UC (90.1%) vs CD (84.3%) (p=0.023), and surgery occurred more frequently in CD (1.9% in UC vs 5.1% in CD, p=0.016). CONCLUSION We found differences when using VDZ in UC vs CD in real life. These parameters can help the physician predict this drug's longterm efficacy.

Abstract
Background Moderate‐to‐severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side‐effects. Dupilumab was recently approved for treatment of adolescent AD. Objectives A multicentre, prospective, real‐world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate‐to‐severe AD was conducted. The main AD clinical phenotypes were also examined. Methods Data of adolescents with moderate‐to‐severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes. Results One hundred and thirty‐nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait‐like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS‐CoV‐2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty‐eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event. Conclusions Dupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID‐19 pandemic era.

Abstract
Inflammatory bowel diseases (IBDs) may be associated with extra-intestinal manifestations. Among these, mucocutaneous manifestations are relatively frequent, often difficult to diagnose and treat, and may complicate the course of the underlying disease. In the present review, a summary of the most relevant literature on the dermatologic manifestations occurring in patients with inflammatory bowel diseases has been reviewed. The following dermatological manifestations associated with IBDs have been identified: (i) specific manifestations with the same histological features of the underlying IBD (occurring only in Crohn's disease); (ii) cutaneous disorders associated with IBDs (such as aphthous stomatitis, erythema nodosum, psoriasis, epidermolysis bullosa acquisita); (iii) reactive mucocutaneous manifestations of IBDs (such as pyoderma gangrenosum, Sweet's syndrome, bowel-associated dermatosis-arthritis syndrome, aseptic abscess ulcers, pyodermatitis-pyostomatitis vegetans, etc.); (iv) mucocutaneous conditions secondary to treatment (including injection site reactions, infusion reactions, paradoxical reactions, eczematous and psoriasis-like reactions, cutaneous infections, and cutaneous malignancies); (v) manifestations due to nutritional malabsorption (such as stomatitis, glossitis, angular cheilitis, pellagra, scurvy, purpura, acrodermatitis enteropathica, phrynoderma, seborrheic-type dermatitis, hair and nail abnormalities). An accurate dermatological examination is essential in all IBD patients, especially in candidates to biologic therapies, in whom drug-induced cutaneous reactions may assume marked clinical relevance.

Abstract
BACKGROUND There is substantial evidence linking disturbed gastrointestinal motility to inflammation. Thus, it is not surprising that abnormalities of gastrointestinal motility play a role in inflammatory bowel disease (IBD), affecting patient outcomes. We performed a review of the literature to investigate the relationship between abnormal gut motility and IBD. METHODS With an extensive literature search, we retrieved the pertinent articles linking disturbed gut motility to IBD in various anatomical districts. RESULTS The evidence in the literature suggests that abnormal gastrointestinal motility plays a role in the clinical setting of IBD and may confuse the clinical picture. CONCLUSIONS Abnormal gut motility may be important in the clinical setting of IBD. However, additional data obtained with modern techniques (e.g., magnetic resonance imaging) are needed to individuate in a more precise manner gastrointestinal motor dysfunctions, to understand the nature of clinical manifestations and properly tailor the treatment of patients.

Abstract
The first infliximab biosimilar for the treatment of inflammatory bowel disease (IBD) was introduced in 2013, and today eight anti-TNF alpha biosimilars (three for infliximab and five for adalimumab) have been approved and licensed by the European Medicines Agency. Biosimilars present great potential in terms of cost saving and possible consequential reinvestment in the health care system. The increasing knowledge about the process of biosimilar development and use in IBD and the publication of many prospective clinical studies and real-life clinical experiences have progressively changed the point of view of IBD physicians. In the present position paper, the Italian Group for the Study of Inflammatory Bowel Disease present and discuss their updated statements and positions on this topic, with emphasis on the concepts of biosimilarity and extrapolation across indications, safety and immunogenicity, interchangeability and switching, automatic substitution, and, finally, patient education about biosimilars.

Abstract
Ulcerative colitis (UC), a chronic, relapsing, remitting disease of the colon and rectum, is characterized by inflammatory ulceration of the mucosa. Current UC therapy relies on controlling acute episodes and preventing relapse. To predict modifications in the natural course of UC, mucosal healing (MH) has emerged as a major treatment goal. Endoscopic evaluation is considered the gold standard for assessing MH, which can be achieved by conventional drugs and biologics in many, but not all, patients. Consequently, interest is focusing on the development of new substances for UC therapy, and new oral agents are in the pipeline. This review will focus on the ability of newly developed oral drugs to induce and maintain MH in UC patients.

Abstract
BACKGROUND Although glucocorticosteroids (GS) and mesalazine are effective and widely employed to treat moderate-to-severe ulcerative colitis (UC), information regarding the factors responsible for response to such therapy is still scarce. One of these factors is thought to be an increased number of mucosal eosinophils. The aim of our study was to determine whether the presence of hypereosinophilia in colonic mucosa of UC patients might influence the short-term response to l treatment with GS and mesasalazine. METHODS Clinical, endoscopic, and pathologic data from patients with a recent diagnosis of moderate UC, who had not undergone treatment, were obtained, and the short-term outcome after 1 month of conventional first-line treatment (mesalazine plus GS) was evaluated. RESULTS There were 53 patients with a median age of 37 years (95% CI 30-47).Overall, at the end of treatment period 16 (30%) patients responded, whereas a response was not observed in the other 37 (70%) patients. Interestingly, all patients of this latter group had colonic mucosal hypereosinophilia. No significant differences were found between the two groups concerning sex and age at diagnosis, but hypereosinophilia was inversely correlated with the duration of the disease (p = 0.054), and significantly correlated to the localization of UC (p = 0.0023). In addition, The Mayo score was significantly higher in patients with hypereosinophilia (median 8; 95% CI 8-9;) when compared to patients without hypereosinophilia (median 7; 95% CI 7-7, p < 0.0001) including the Mayo endoscopic subscore (median 3; 95% CI 2-3 vs median 2; 95% CI 2-2, respectively; p = 0.007). CONCLUSIONS The presence of colonic mucosal hypereosinophilia may be useful to predict the short-term outcome to conventional first-line therapy in treatment-naïve UC patients. It remains to be seen whether this might be important in modifying the first-line therapy in this subgroup of patients.

Abstract
The aim of the study was to retrospectively review the outcome of neonatal ureteropelvic junction obstruction with a good renal function and a poor drainage at a first diuretic renal scan, in cases where surgery was recommended on the basis of a loss of renal function, worsening of hydronephrosis or occurrence of clinical symptoms. Hydronephrosis was graded from 1 to 4 or as ureteral tract dilatation (UTD) P1 to UTD P3. During follow-up, 15 out of 38 patients (34.2%) required surgery while 25 out of 38 (65.8%) could have been managed conservatively. In patients with grade 2, 3, and 4 hydronephrosis, the ureteropelvic junction obstruction resolved or improved spontaneously in 100%, 63%, and 33% of cases (in 100% of UTD P1, 67% of UTD P2, and 50% of UTD P3), respectively. The median of follow-up was 14 years. Chi-square test showed a significant relationship between initial grade of hydronephrosis or UTD and the possibility of an efficient conservative management (p = 0.0088 and p = 0.0460).Conclusion: Conservative management can be safely achieved in ureteropelvic junction obstruction with poor drainage. Scheduled controls are needed for early discovery of functional renal deterioration. High-grade hydronephrosis is unlikely to resolve spontaneously and is often accompanied by a loss of renal function during the first years of life. What is Known: • There is controversy about which management should be adopted in infants with unilateral ureteropelvic junction obstruction with poor drainage but good differential renal function. What is New: • Long-term follow-up suggests that conservative management can be safely achieved also in unilateral ureteropelvic junction obstruction with poor drainage in more than 60% of cases, even if high-grade hydronephrosis is unlikely to resolve spontaneously and it is often accompanied by a loss of renal function during the first years of life. In our experience, surgical intervention was required in more than 50% of cases before 1 year of life and in all cases before 3 years of life.

Abstract
BACKGROUND Although antitumor necrosis factor alfa (TNFα) agents are widely used to treat patients with inflammatory bowel diseases (IBD) - both Crohn's disease (CD) and ulcerative colitis (UC) - there is still some uncertainty in the cell type expressing TNFα in human ileo-colonic segments. AIMS We investigated the immunohistochemical (IHC) expression of TNFα in the ileo-colonic segments of patients with both active CD and UC, to establish its anatomic and cellular localization in the inflamed sites. Our aim was to identify patients potentially resistant to anti TNFα agents. PATIENTS AND METHODS Ileo-colonic slides of complete histological mapping of patients with CD and UC before any treatment was started were obtained, and serial sections assessed for TNFα expression, together with IHC markers for lymphocytes, macrophages, and plasma cells. RESULTS TNFα was expressed in almost all inflamed segments of IBD patients, albeit with different strength, and was present, in addition to lymphocytes and, to a lesser extent, to macrophages, in plasma cells, where it had a strong positivity, as also demonstrated by colocalization of specific IHC staining. The expression of TNFα was mostly focal in CD patients and more diffuse in UC patients, likely due to the different patterns of inflammation (transmural and mucosal) of the two entities. CONCLUSIONS In IBD, TNFα is strongly expressed also in plasma cells, and it is easily evidenced by conventional IHC techniques. It remains to be established whether this observation might be useful in future to establish in routine biopsy samples whether patients may be responsive to treatments toward this cytokine.

Abstract
The concept of remission for patients with inflammatory bowel diseases has recently evolved, and should also include histological healing of the mucosa, difficult to evaluate since there is no agreement on pathological scores and those available are quite complex to use in the daily routine. We evaluated the possible usefulness of a simplified pathological score to assess histological healing of the mucosa in inflammatory bowel diseases patients compared with four commonly proposed pathological scores. Slides from 24 patients (12 Crohn’s disease, 12 ulcerative colitis, age range 24–62 years), pre- and post-treatment with biological agents and displaying endoscopic remission were assessed by two pathologists. Pre- and post-treatment results and the time employed to calculate the various scores were obtained. All scores were useful to document highly significant post-treatment decreases of histological activity. However, the simplified score needed significant less time to be calculated for each slide, had high inter-rater agreement, and avoided subjectivity from the pathologists. The simplified score is easy to calculate and seems apt to document histological healing of the mucosa, in a manner similar to the more complex scores. It remains to be established whether this score could simplify the daily routinary practice in this context.

Abstract
Basal plasmacytosis is an early-onset and highly predictive feature of inflammatory bowel disease (IBD), but may have several restrictions in routine histology. Considering evidences about cooperation between eosinophils and plasma cells in IBD pathogenesis, we investigated immunostain of these two cells as a marker of disease. 343 samplings from 83 patients (52 IBD, 31 non-IBD colitis) were evaluated. The sections were stained with monoclonal antibodies against plasma cells (CD138 and MUM1), and eosinophils (CD193). Eosinophilia-associated basal plasmacytosis (EBP) was related with the histologic diagnosis of IBD (90.3% IBD and 35.4% non-IBD colitides, p < 0.005, sensitivity 90.4%). A strong relation was detected between the occurrence of EBP and (i) the achieving of a complete endoscopic mapping; (ii) the presence of other characteristic lesions of IBD in single segmental sampling, although EBP was evident in more than 40% of samples without other IBD-related lesions. EBP is a sensitive histologic feature of IBD, especially at the first endoscopic sampling, even in the absence of the other characteristic histologic lesions, and may help in formulating a more precise diagnosis in this setting.

Abstract
Celiac disease (CD) and inflammatory bowel disease (IBD), such as Crohn's disease (CrD) and ulcerative colitis (UC), are chronic inflammatory condition of the gastro-intestinal tract. The prevalence of IBD in celiac patients has been reported as 5-10 times higher than in the general population. The possibility of the presence of CD in IBD should be considered in IBD patients with long-term iron deficiency anemia (IDA) not responsive to iron supplementation. Non-celiac gluten sensitivity (NCGS) is characterized by intestinal and extra intestinal symptoms due to the ingestion of gluten-containing food in subject without CD and/or wheat allergy. Patients with Crohn's disease and SR-NCGS were more significantly affected by joint pains compared to UC patients (50% versus 11.1%). In Crohn's patients, a higher percentage of fatigue (50% versus 38.9%) and headache (27.3% versus 22.2%) was evident. For the association between NCGS and IBD new studies are warranted and, at this moment, a gluten free diet (GFD) may be useful more in CrD than in UC.

Abstract
BACKGROUND The most frequent form of inflammatory bowel disease (IBD) in dogs is represented histologically, by lymphoplasmacytic enteritis (LPE), a histological category, often associated with other morphologic alterations including lymphangiectasia (LE). However, literature data on this latter topic are quite scarce and have mostly been obtained in single reports or in small series. AIM We evaluated some morphologic parameters of intestinal villi and lacteals in a large cohort of dogs, and correlated them with serum albumin and cholesterol values. PATIENTS AND METHODS We investigated 136 dogs (94 with LPE, and 42 with gastrointestinal problems different from IBD) and analyzed their clinical, laboratory (albumin and cholesterol values), endoscopic, and histologic variables. RESULTS The LPE group showed significantly impaired clinical, laboratory, endoscopic, and histologic variables compared to controls. Affected dogs showed significant correlations between canine inflammatory bowel disease activity index (CIBDAI) scores and endoscopic and histologic variables. Moreover, the grade of hematologic changes were strongly related to the intestinal histologic variables, in particular those concerning villous and lacteals morphology. CONCLUSION Dogs with LPE had intestinal histologic abnormalities (height, width, height/width ratio, calculated for both villi and lacteals), whose degree correlated with the severity of hypoalbuminemia and hypocholesterolemia. Evaluation of endoscopic and histologic variables in association to the clinical findings may reveal useful insights for the pathogenesis of LPE and, hopefully, might lead to more targeted therapeutic approaches.

Abstract
BACKGROUND Inflammatory conditions affecting the gut may cause motility disturbances, and ulcerative colitis - one of the main disorders among the inflammatory bowel diseases - may display abnormal colonic motility. AIM To review the abnormalities of the large bowel in ulcerative colitis, by considering the motility, laboratory (in vitro) and pathological studies dealing with this topic. METHODS A comprehensive online search of Medline and the Science Citation Index was carried out. RESULTS Patients with ulcerative colitis frequently display colonic motor abnormalities, including lack of contractility, an increase of propulsive contractile waves, an excessive production of nitric oxide, vasoactive intestinal polypeptide nerves, interleukin 1 beta, neurotensin, tachykinins levels and the weaker action of substance P, likely related to a neuromuscular dysfunction due to the inflammatory process. CONCLUSIONS A better understanding of the pathophysiological grounds of altered colonic motility in ulcerative colitis may lead to a more in-depth knowledge of the accompanying symptoms and to better and more targeted therapeutic approaches.

Abstract
BACKGROUND Although it is usually not difficult to diagnose inflammatory bowel disease (IBD) on surgical resection specimens, difficulties sometimes arise in differentiating these entities from other forms of colitis on endoscopic biopsy specimens. Basal plasmacytosis is considered as an early feature of IBD colitis, but it is rare in non-IBD colitides. AIMS We assessed the value of basal plasmacytosis as an individual variable in untreated patients with colitis. PATIENTS AND METHODS Archival slides of patients with untreated colitis (66 IBD and 49 non-IBD) and 20 controls with complete (from the terminal ileum to the rectum) endoscopic biopsy sampling were evaluated blindly for the presence of basal plasmacytosis and a possible association with the presence of eosinophils in the same anatomical location. RESULTS Overall, basal plasmacytosis was present in at least one anatomical segment in 58% of cases, and it was always present in patients with IBD, whereas it was sparsely found (9%) in patients with other colitides and in controls. Basal plasmacytosis in three or more segments had more than 80% probability for a patient to be classified as IBD, with the segmental distribution being different between ulcerative colitis and Crohn's disease. Additionally, basal plasmacytosis was always accompanied by eosinophils intermingled with plasma cells in the same anatomical position. CONCLUSION As an individual feature, basal plasmacytosis (accompanied by eosinophils) is a strong feature suggesting IBD, particularly when present in three or more colonic segments. This fact may be useful in the evaluation of endoscopic biopsies from patients with "colitis".

Abstract
The relationship between motility and inflammatory gastrointestinal disorders is at the same time complex and intriguing since these conditions might share some genetic, environmental, immunological and microbial predisposing factors. In addition, significant symptom overlapping may occur, muddling the waters within the clinical context. Although on one hand this represents a challenge for the clinician for a potential under- or over-treatment and diagnostic delay, on the other hand it possibly represents an opportunity for the researcher to better disclose the intimate relationship between chronic (often low-grade) inflammation, motor disorders and deranged sensory function. The best example is probably represented by Crohn’s disease and ulcerative colitis. In fact, a number of gastrointestinal motor disorders have been described in association with these diseases, disorders which span from the esophagus to the anorectum, and which will be extensively covered in this review. It is conceivable that at least part of this derangement is strictly related to inflammatory cytokine trafficking and neuromuscular changes; however, given the high prevalence of functional gastrointestinal disorders in the general population, this overlap might also be serendipitous. However, it is worth noting that literature data on this topic are relatively scarce, sometimes quite outdated, and mostly focused on the interplay between irritable bowel syndrome and inflammatory bowel disease. Nevertheless, both researchers and clinicians must be aware that symptoms related to gastrointestinal motility disorders may be highly prevalent in both active and inactive inflammatory bowel disease, correlate with greater psychological comorbidity and poorer quality of life, and may negatively influence the therapeutic approaches.

Abstract
Since the introduction of biological therapy, endoscopic and histological remission, i.e. mucosal healing, has become an important therapeutic goal in Crohn's Disease and Ulcerative Colitis. Mucosal healing is associated with lower rates of hospitalization and surgery, although its role in preventing progression and changing the natural history of the disease has not been clearly demonstrated. A precise definition of mucosal healing has not yet been established, although the concept used in clinical trials is the "complete absence of all inflammatory and ulcerative lesions in all segments of gut" at endoscopy. This definition does not include mucosal improvement and does not distinguish among grades of mucosal healing. In both Crohn's Disease and Ulcerative Colitis trials, several qualitative and quantitative numeric endoscopic indices have been proposed to measure and distinguish endoscopic changes. In addition, the microscopic features associated with inflammatory bowel diseases are considerably modified by the course of the disease and the treatments adopted. However, it is not yet clear whether microscopic healing should be a primary endpoint in clinical trials. In this paper we discuss endoscopic and histological findings and the limitations of the endoscopic and histological indices as a basis for a standardised diagnosis of mucosal healing.

Abstract
BACKGROUND & AIMS Coeliac disease patients frequently display mild elevation of liver enzymes and this abnormality usually normalizes after gluten-free diet. To investigate the cause and prevalence of altered liver function tests in coeliac patients, basally and after 1 year of gluten-free diet. PATIENTS AND METHODS Data from 245 untreated CD patients (196 women and 49 men, age range 15-80 years) were retrospectively analysed and the liver function tests before and after diet, as well as associated liver pathologies, were assessed. RESULTS Overall, 43/245 (17.5%) patients had elevated values of one or both aminotransferases; the elevation was mild (<5 times the upper reference limit) in 41 (95%) and marked (>10 times the upper reference limit) in the remaining 2 (5%) patients. After 1 year of gluten-free diet, aminotransferase levels normalized in all but four patients with HCV infection or primary biliary cirrhosis. CONCLUSIONS In coeliac patients, hypertransaminaseaemia at diagnosis and the lack of normalization of liver enzymes after 12 months of diet suggest coexisting liver disease. In such instance, further evaluation is recommended to exclude the liver disease. Early recognition and treatment of coeliac disease in patients affected by liver disease are important to improve the liver function and prevent complications.

Abstract
Treatment of inflammatory bowel disease (IBD) is traditionally based on several drugs, including salicylates, corticosteroids, and antibiotics; in addition, the therapeutic armamentarium has considerably evolved with the advent of newer, effective therapeutic measures (such as the biological agents) that are able to improve in a considerable manner both the clinical and endoscopic variables. Thus, mucosal healing, at least considered from an endoscopic point of view, is today regarded as the ultimate endpoint for treatment of these conditions. However, it is also increasingly clear that endoscopic healing is not necessarily paralleled by histological healing; There are few doubts that the latter should be considered as a true, objective healing and the ultimate goal to reach when treating patients with IBD. Unfortunately, and surprisingly, only a few, incomplete, and somewhat conflicting data exist on this topic, especially because there is still the need to standardize both histological assessment and the severity grading of these disorders; Issues that have not been yet been resolved for clinical practice and therapeutic trials. Hopefully, with the help of an increased awareness on the clinical researchers’ side, and the availability of dedicated pathologists on the other side, this matter will be effectively faced and resolved in the near future.

Abstract
BACKGROUND Mast cells are involved in visceral hypersensitivity and motor activity of the gastrointestinal tract. However, there is almost no information concerning mast cells in constipated patients. AIMS The purpose of this study was to investigate mast cells distribution in all colonic layers in controls and severely constipated patients with obstructed defecation. METHODS Full-thickness specimens from colons of patients undergoing surgery for obstructed defecation due to refractoriness to other therapeutic interventions (n = 11), compared to controls, were obtained and the number of mast cells (evaluated by specific monoclonal antibodies) were counted in the whole viscus and in the various colonic segments (cecum, ascending, transverse, descending, and sigmoid). RESULTS Compared to controls, constipated patients had significantly higher numbers of mast cells, both as an overall number and in single colonic segments. This increase was especially evident in the mucosa and submucosa. Mast cells were homogeneously represented in the various segment of the large bowel, in both controls and patients. Degranulated mast cells were found to be close to enteric glial cells and glial filaments. CONCLUSIONS Colonic mast cells are increased in obstructed defecation patients. This might represent a vicariating mechanism to the impaired colonic propulsive activity of these patients.

Abstract
Apart from inflammatory bowel diseases (IBD), there are several other form of colitis that may resemble macroscopically IBD, entering the differential diagnosis. These forms are represented by infectious colitis, ischemic colitis, pseudomembranous colitis, colitis related to diverticular disease, colitis related to mucosal prolapse, drug colitis, allergic colitis, and microscopic colitis. However, to distinguish between these forms is not always easy, and it frequently requires a strict interrelationship between the pathologist and the gastroenterologist. Here we discuss the more frequent forms of non- inflammatory bowel diseases colitides, trying to give useful hints for helping the clinician to better understand the extent to which the pathologist is called to give a definitive response in the differential diagnosis of these entities.

Abstract
BACKGROUND Bowel ultrasound has been shown to be a useful tool to evaluate patients with inflammatory bowel disease, especially Crohn's disease. However, such data are still scarce in ulcerative colitis patients. AIMS To establish the value of bowel ultrasound in moderate to severe ulcerative colitis patients, and compare these data with endoscopic findings. PATIENTS AND METHODS Endoscopic, ultrasound and C-reactive protein data from 51 patients with moderate to severe ulcerative colitis observed during a 3-year period were retrospectively obtained and analysed. RESULTS All patients displayed pathological thickness (>4 mm) of the colon wall. This value strongly correlated with C-reactive protein values (p=0.0001) and the endoscopic score (p<0.0001). Also, a strong correlation (p<0.0001) was found between CRP values and endoscopic score. CONCLUSIONS Bowel ultrasound, in expert hands, may represent a useful adjunctive (or first line) tool for the evaluation of patients with moderate to severe ulcerative colitis.

Abstract
Inflammatory bowel disease (IBD) frequently affects young patients of childbearing age. Treatments for inflammatory bowel disease include immunosuppressive, cytotoxic and surgical therapies. Azathioprine is frequently used to treat patients with steroid dependent IBD. We report the case of a patient with ulcerative colitis, treated with azathioprine prior to conception and during the subsequent pregnancy with the subsequent successful delivery of healthy twins. Although some potential risks indeed exist, the use of AZA may not be harmful to the mother or the fetus in many instances.

Abstract
Inflammatory bowel diseases (IBD) represent important chronic conditions affecting the gastrointestinal tract in man. However, similar disorders are found in several animal species and the IBD affecting dogs are particularly important. These are encompassed by an umbrella of probably several different entities with common symptoms, some of which seem to share striking similarities with human conditions. This review will focus on the actual knowledge of IBD in dogs, and attempt to identify differences and similarities with human IBD conditions.

Abstract
BACKGROUND Enteric nervous system abnormalities have been described in patients with inflammatory bowel diseases. However, the mechanisms responsible for these abnormalities remain to date largely unknown. AIMS We investigated the potential role of apoptotic phenomena in enteric neurons and enteroglial cells in patients with inflammatory bowel diseases. PATIENTS AND METHODS Full-thickness surgical specimens of 19 patients undergoing surgery for medically refractory disease (9 from the ileum of patients with Crohn's disease, 10 from the colon of patients with ulcerative colitis) were assessed for the presence of enteric neurons and enteroglial cells and for their apoptosis by two immunohistochemical methods, one also able to distinguish apoptosis from necrosis. The results were compared with those obtained in control specimens. RESULTS Concerning Crohn's disease, the ileal segments displayed a significant increase of apoptotic enteric neurons and enteroglial cells in both the submucous and the myenteric plexus compared to controls. In patients with ulcerative colitis, compared to controls, apoptotic phenomena were significantly reduced in enteric neurons, whereas they were increased in the enteroglial cell population (submucous and myenteric plexus). CONCLUSIONS In patients with inflammatory bowel disease apoptotic phenomena involve both enteric neurons and enteroglial cells, and may play a role in the abnormalities of the enteric nervous system. The importance of these findings in the pathophysiology of these conditions remains to be determined.

Abstract
Various studies have described abnormalities of the enteric nervous system (ENS) in tissue samples from patients with chronic idiopathic inflammatory bowel diseases (IBD). The distribution of density of the different cell types of the ENS was however not studied in a systematic way. The aim of this study was to examine the density of neurons, enteroglial cells and interstitial cells of Cajal (ICC) in the different plexuses of the ENS in samples from patients with Crohn's disease (CD), ulcerative colitis (UC) and controls. Tissue samples from 16 patients with CD (ileum) and 16 patients with UC obtained in involved and non-involved areas were studied using immunohistochemistry with antibodies directed against neuron-specific enolase, S100, C-Kit and CD3. Sections were analysed blindly by two pathologists and the number of positive cells was counted for each type. Overall, an increase was noted for neuronal cell bodies, enteroglia and ICC in the deep muscular plexus in CD. In uninvolved areas of CD patients, the number of enteroglial cells was decreased. In UC, an increase of ICC in the muscularis propria and enteroglial cells was observed in diseased tissue. The study confirms the presence of abnormalities of the different cells of the ENS in IBD. The presence of lesions in samples from uninvolved areas, such as a reduction of enteroglia, supports a pathogenetic role of the ENS.

Abstract
BACKGROUND Anal endosonography reliably visualizes and identifies anal sphincter abnormalities. However, dedicated probes are quite expensive. We evaluated a simple and less-costly procedure for anal endosonography involving the insertion of the endoscope through a disposable anoscope filled with standard ultrasound gel in terms of patient satisfaction and the simplicity of the procedure in comparison with the standard technique in a unit that already had echoendoscopes available. METHODS The two techniques were used in 35 subjects without anal abnormalities and data on the simplicity of the procedures, patient discomfort, the quality of images, and the time needed to perform the procedures were compared. RESULTS All the variables under investigation scored significantly better with the modified technique compared to the standard one. No differences in thickness of either the internal or the external anal sphincter were found between the two methods. CONCLUSIONS This simple and less-costly adaptation of anal ultrasonography allows good quality examinations to be performed with better patient comfort in units with echoendoscopes already available, avoiding the need for a more expensive dedicated probe.

Abstract
The role of enteric glial cells has somewhat changed from that of mere mechanical support elements, gluing together the various components of the enteric nervous system, to that of active participants in the complex interrelationships of the gut motor and inflammatory events. Due to their multiple functions, spanning from supporting elements in the myenteric plexuses to neurotransmitters, to neuronal homeostasis, to antigen presenting cells, this cell population has probably more intriguing abilities than previously thought. Recently, some evidence has been accumulating that shows how these cells may be involved in the pathophysiological aspects of some diseases. This review will deal with the properties of the enteric glial cells more strictly related to gastrointestinal motor function and the human pathological conditions in which these cells may play a role, suggesting the possibility of enteric neuro-gliopathies.

Abstract
The enteric glial cells, in addition to being support structures for the enteric nervous system, have many other additional roles, such as modulators for the homeostasis of enteric neurons, cells involved in enteric neurotransmission and antigen-presenting cells. Moreover, in the last years, data have been accumulating that demonstrate a possible active role of these cells in the pathophysiology of gastrointestinal motor activity. Thus, as also shown by recent evidence in both experimental animal models, and in some human diseases, alterations of enteric glial cells might have some role in the development of intestinal motor abnormalities.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) and cyclo-oxygenase (COX)-2 selective inhibitors (COXIBs) are widely used drugs. However, their use is hampered by gastrointestinal, cardiovascular and renal side effects. Nitric oxide (NO)-releasing NSAIDs, NO-NSAID, are a new class of anti-inflammatory and analgesic drugs generated by adding a nitroxybutyl or a nitrosothiol moiety to the parent NSAID via a short-chain ester linkage. While efficacy of nitrosothiol-NSAIDs still awaits investigation, nitroxybutyl-NO-NSAIDs have been extensively studied in humans. The combination of balanced inhibition of the two main COX isoforms with release of NO confers to NO-NSAIDs reduced gastrointestinal and cardiorenal toxicity. It is suggested that the NO, which is released as the compounds are broken down, may counteract the consequences of the NSAID-induced decrease in gastric mucosal prostaglandins. Recent clinical trials with NO-NSAIDs have provided data consistent with pre-clinical observations.

Abstract
OBJECTIVE To evaluate the reproducibility of sonographic measurement of the lower uterine segment in pregnant women at term. METHODS Two independent observers performed transabdominal sonography on 129 women between 36 and 38 weeks of gestation who had had a previous Cesarean section. Sonography was performed when the patients had a full and a half-full bladder; in 100 patients, the measurements were also performed transvaginally, with the patients having an empty bladder. Agreement was quantified by the intraclass correlation coefficient and, using a cut-off of 3.5 mm, by the kappa coefficient. RESULTS The intraobserver agreement was generally high (intraclass correlation coefficient > 0.90). The interobserver agreement was higher on transvaginal (intraclass correlation coefficient, 0.94) compared with transabdominal (0.70 and 0.84, with full and half-full bladder, respectively) ultrasound. The kappa coefficient was 0.75 transvaginally, compared with 0.34 and 0.54 using the transabdominal approach, with full and half-full bladder, respectively. CONCLUSION The agreement between two observers for sonographic transvaginal measurement of the lower uterine segment can be considered good, compared with poor to moderate agreement using the transabdominal approach.

Abstract
BACKGROUND & AIMS Hydrogen sulfide (H(2)S), an endogenous gaseous mediator that causes vasodilation, is generated in mammalian tissues by cystathionine beta-synthase (CBS) and cystathionine-gamma-lyase (CSE). Here, we have investigated the role of H(2)S in a rodent model of nonsteroidal anti-inflammatory drug (NSAID) gastropathy. METHODS Rats were given acetyl salycilic acid (ASA) or an NSAID alone or in combination with NaHS, an H(2)S donor, and killed 3 hours later. Gastric blood flow was measured by laser-Doppler flowmetry, whereas intravital microscopy was used to quantify adhesion of leukocytes to mesenteric postcapillary endothelium. RESULTS At a dose of 100 micromol/kg, NaHS attenuated by 60%-70% the gastric mucosal injury, and tumor necrosis factor (TNF)-alpha, intercellular adhesion molecule (ICAM)-1, and lymphocyte function-associated antigen (LFA)-1 mRNA up-regulation induced by NSAIDs (P < .05) NaHS administration prevented the associated reduction of gastric mucosal blood flow (P < .05) and reduced ASA-induced leukocyte adherence in mesenteric venules. NaHS did not affect suppression of prostaglandin E(2) (PGE(2)) synthesis by NSAIDs. Glibenclamide, a K(ATP) channel inhibitor, and DL-propargylglycine, a CSE inhibitor, exacerbated, whereas pinacidil, a K(ATP) opener, attenuated gastric injury caused by ASA. Exposure to NSAIDs reduced H(2)S formation and CSE expression (mRNA and protein) and activity by 60%-70%. By promoter deletion and mutation analysis, an Sp1 consensus site was identified in the CSE promoter. Exposure to NSAIDs inhibits Sp1 binding to its promoter and abrogates CSE expression in HEK-293 cells transfected with a vector containing the core CSE promoter. Exposure to NSAIDs inhibits Sp1 and ERK phosphorylation. CONCLUSIONS These data establish a physiologic role for H(2)S in regulating the gastric microcirculation and identify CSE as a novel target for ASA/NSAIDs.

Abstract
Nitric oxide (NO) releasing non-steroidal anti-inflammatory drugs (NSAIDs) are a new class of anti-inflammatory agents obtained by adding an NO releasing moiety to existing NSAIDs. They have also christened as COX inhibiting NO-donating drugs (CINOD). Preclinical and clinical studies suggest that CINOD inhibit COX-1 and COX-2 activities while cause less adverse effects on gastrointestinal tract in comparison to conventional NSAIDs and coxibs and reduce systemic blood pressure. A different class of NO-donating drugs has been obtained by coupling NO to aspirin. These NO-releasing aspirins are new chemical entities that maintain and possibly expands the pharmacological properties of aspirin, but spare the gastrointestinal mucosa. Animal studies have shown that CINOD and NO-aspirins maintain gastric mucosal blood flow and reduce leukocyte-endothelial cell adherence.

Abstract
Hydrogen sulfide (H(2)S) functions as a neuromodulator, but whether it modulates visceral perception and pain is unknown. Cystathionine beta-synthase (CBS) and cystathionine-gamma-lyase (CSE) mediate enzymatic generation of H(2)S in mammalian cells. Here we have investigated the role of H(2)S in modulating nociception to colorectal distension, a model that mimics some features of the irritable bowel syndrome. Four graded (0.4-1.6 ml of water) colorectal distensions (CRDs) were produced in conscious rats (healthy and postcolitic), and rectal nociception was assessed by measuring the behavioral response during CRD. Healthy rats were administered with sodium hydrogen sulfide (NaHS) (as a source of H(2)S), L-cysteine, or vehicle. In a second model, we investigated nociception to CRD in rats recovering from a chemically induced acute colitis. We found that CBS and CSE are expressed in the colon and spinal cord. Treating rats with NaHS resulted in a dose-dependent attenuation of CRD-induced nociception with the maximal effect at 60 micromol/kg (p < 0.05). Administration of L-cysteine, a CSE/CBS substrate, reduced rectal sensitivity to CRD (p < 0.05). NaHS-induced antinociception was reversed by glibenclamide, a ATP-sensitive K(+) (K(ATP)) channel inhibitor, and N(omega)-nitro-L-arginine methyl ester hydrochloride (L-NAME), a nitric-oxide (NO) synthase inhibitor. The antinociceptive effect of NaHS was maintained during the resolution of colon inflammation induced by intrarectal administration of a chemical irritant. In summary, these data show that H(2)S inhibits nociception induced by CRD in both healthy and postcolitic rats. This effect is mediated by K(ATP) channels and NO. H(2)S-releasing drugs might be beneficial in treating painful intestinal disorders.
