Abstract
BackgroundFibromyalgia (FM) is a common chronic disorder characterized by widespread pain, fatigue, sleep disturbances and functional symptoms, reaching a prevalence of 2–3% worldwide. It can present as a comorbidity in patients with concomitant chronic disease and can have a significant impact on the quality of life. There are very few studies on the prevalence and the impact of FM in patients with inflammatory bowel disease (IBD).ObjectivesThe aims of this study were to assess the prevalence of FM in a cohort of patients with IBD, and to evaluate the impact of FM on the quality of life of those patients.MethodsConsecutive patients with IBD were enrolled from August to November 2021 in two IBD units, patients with severe disease activity according to the Crohn’s disease activity index (CDAI) and to the Mayo score for UC, or with other concomitant chronic diseases were excluded. Clinical and demographic data and Patient Reported Outcomes (PROs) (Widespread Pain Index (WPI), Symptom Severity Score (SSS), IBD Questionnaire (IBD-Q), Depression anxiety stress scales-21 (DASS-21), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Impact of event scale-revised (IES-R), Pittsburgh Sleep Quality Index (PSQI)) were collected. FM was diagnosed according to 2011 ACR classification criteria by an expert rheumatologist. Mann-Whitney test, chi-square test, and Student t test were used for statistical analyses. A multivariate analysis was performed to estimate the effect of independent variables (BMI, age, CRP, CDAI, Mayo score, WPI, DASS-21, FACIT-F, PSQI) on patients’ quality of life (IBD-Q). A p value < 0.05 was considered as significant.ResultsA total of 196 IBD patients were enrolled (86 female (44%) with a mean age of 50 ± 15 yo), 105 with Crohn’s disease (CD) and 91 with ulcerative colitis (UC). 147 patients were in remission, 35 had low disease activity and 14 moderate disease activity. The overall prevalence of FM in the IBD cohort was 17/196 (8.7%) [95% IC 5% – 13%], 10 (11.6%) women and 7 (6.3%) men; with a prevalence of 7.6% (8/105) in CD and 9.9% (9/91) in UC.In Table 1 are indicated the characteristics of patients with IBD + FM and IBD alone. No significant demographic and clinical differences between the two groups were detected.Table 1.IBD + FM (n=17)IBD without FM (n=179)pFemale/Male (%)10/7 (59%/41%)75/102 (42%/58%)0.19Age, years (SD)56.8 (± 13)48.5 (± 17)0.06BMI (SD)21 (± 8.7)23.7 (± 4.8)0.46CD (%)/UC (%)8 (47%)/9 (53%)97 (54%)/82 (46%)0.57CRP, median (SD)0.16 mg/dL (± 2.8)0.2 mg/dL (± 1.5)0.87IBD remission14 (82%)133 (74%)0.33IBD low disease activity1 (6%)34 (19%)IBD moderate disease activity2 (12%)12 (7%)Ongoing conventional treatment6 (35%)70 (39%)0.27Ongoing biological treatment11 (65%)112 (63%)0.42 PROsIBD-Q150.3176.9<0.001DASS-21 DEPRESSION15.38.24<0.001DASS-21 ANXIETY16.69.13<0.001DASS-21 STRESS13.46.13<0.001FACIT-F25.538.2<0.001IES-R36.916.3<0.001The quality of life among IBD patients and IBD + FM patients, assessed with IBD-Q, appear significantly lower (p <0.001) in the second group. Similar results were obtained evaluating depression, anxiety, stress, chronic fatigue, and patients’ discomfort (Table 1).The multivariate analysis demonstrated that the variables influencing the quality of life (IBD-Q) were the disease activity (CDAI) (p 0.0256), the chronic fatigue (FACIT-F) (p 0.0061) and sleep disturbances (PSQI) (p 0.0440), for CD; while for UC the only variable that correlate with IBD-Q was the disease activity (Mayo score) (p 0.0129).ConclusionFM is a common disorder especially in patients with other concomitant chronic diseases. This study reported a prevalence of FM of 8.7% in IBD patients without any significant differences between CD and UC. Moreover, the comorbidity of FM in IBD can have a considerable impact on quality of life and on measures of disease severity, with worst values in all PROs measurements.Disclosure of InterestsNone declared

Abstract
BACKGROUND In a phase 2 study, mongersen, an oral antisense oligonucleotide targeting Smad7, was effective in inducing clinical remission in approximately 60% of patients with active Crohn's disease (CD). AIM In a post hoc analysis to evaluate those patient disease characteristics that may have influenced the efficacy and safety of mongersen therapy. METHODS Patients with steroid-dependent/resistant, active CD were randomised to mongersen 10, 40 or 160 mg/day or placebo for 2 weeks; patients were followed for 10 weeks. Clinical remission [Crohn's Disease Activity Index (CDAI) score <150] and clinical response (CDAI score reduction ≥100 points) were assessed at weeks 2, 4 and 12 for these subgroups: disease duration <5/≥5 years, human serum C-reactive protein (hsCRP) <3/≥3 mg/L, and CDAI at baseline ≤260/>260. Additional patient baseline and disease characteristics were explored. RESULTS Clinical remission and response rates were significantly higher in patients receiving mongersen 40 and 160 mg/day but not 10 mg/day vs. placebo and independent of disease duration and hsCRP. Patients with baseline CDAI ≤260 had significantly higher remission rates with 40 and 160 mg/day. In patients with baseline CDAI >260, remission rates were statistically greater with 160 mg/day and numerically better with 40 mg/day vs. placebo. Adverse event rates were similar across treatment groups. Mongersen was safe and well tolerated. CONCLUSIONS Patients with higher CDAI scores achieved clinical remission most frequently with the highest mongersen dose. Disease duration and baseline human serum C-reactive protein did not appear to significantly impact efficacy of mongersen in this study (EudraCT Number: 2011-002640-27.).

Abstract
Trying to conceive and being pregnant is an emotional period for those involved. In the majority of patients suffering from inflammatory bowel disease, maintenance therapy is required during pregnancy to control the disease, and disease control might necessitate introduction of new drugs during a vulnerable period. In this updated consensus on the reproduction and pregnancy in inflammatory bowel disease reproductive issues including fertility, the safety of drugs during pregnancy and lactation are discussed.

Abstract
The management of patients with IBD requires evaluation with objective tools, both at the time of diagnosis and throughout the course of the disease, to determine the location, extension, activity and severity of inflammatory lesions, as well as, the potential existence of complications. Whereas endoscopy is a well-established and uniformly performed diagnostic examination, the implementation of radiologic techniques for assessment of IBD is still heterogeneous; variations in technical aspects and the degrees of experience and preferences exist across countries in Europe. ECCO and ESGAR scientific societies jointly elaborated a consensus to establish standards for imaging in IBD using magnetic resonance imaging, computed tomography, ultrasonography, and including also other radiologic procedures such as conventional radiology or nuclear medicine examinations for different clinical situations that include general principles, upper GI tract, colon and rectum, perineum, liver and biliary tract, emergency situation, and the postoperative setting. The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas such as the comparison of diagnostic accuracy between different techniques, the value for therapeutic monitoring, and the prognostic implications of particular findings.

Abstract
The assessment of the surface free energy (SFE) of a material permits to control and predict a large number of physicochemical properties of a solid surface and its reactivity. Here, the surface energies of a series of bare and fluorinated silanes are determined by means of different semi-empirical models on the grounds of contact angle determinations for different solvents. Literature data are also considered in order to produce a series of films with increasing SFE. Wetting envelopes (WE) are obtained for the various surfaces in order to predict the wettability of the films by numerous commonly employed solvents. The polar and disperse components of the surface energies are obtained by the Owens-Wendt-Rabel-Kaelbe (OWRK) method; the values of the polar components are compared with gas-phase dipole moments obtained by theoretical calculations employing semi-empirical Hamiltonians. The sequences of the polar components of the SFE and of the calculated dipole moments for the different molecules are strictly the same. The interplay between theoretical and experimental approaches proves efficient in predicting the behavior of different systems and it could be employed in tuning the SFE of a solid surface with respect to its final applications.

Abstract
In 1997, the first consensus guidelines for haematopoietic SCT (HSCT) in autoimmune diseases (ADs) were published, while an international coordinated clinical programme was launched. These guidelines provided broad principles for the field over the following decade and were accompanied by comprehensive data collection in the European Group for Blood and Marrow Transplantation (EBMT) AD Registry. Subsequently, retrospective analyses and prospective phase I/II studies generated evidence to support the feasibility, safety and efficacy of HSCT in several types of severe, treatment-resistant ADs, which became the basis for larger-scale phase II and III studies. In parallel, there has also been an era of immense progress in biological therapy in ADs. The aim of this document is to provide revised and updated guidelines for both the current application and future development of HSCT in ADs in relation to the benefits, risks and health economic considerations of other modern treatments. Patient safety considerations are central to guidance on patient selection and HSCT procedural aspects within appropriately experienced and Joint Accreditation Committee of International Society for Cellular Therapy and EBMT accredited centres. A need for prospective interventional and non-interventional studies, where feasible, along with systematic data reporting, in accordance with EBMT policies and procedures, is emphasized.

Abstract
BACKGROUND Ulcerative colitis (UC) is characterised by impaired fatty-acid oxidation; l-carnitine has a key role in fatty-acid metabolism and short-chain fatty acids such as butyrate and propionate are important energy source for intestinal epithelial cells. AIM To evaluate efficacy and safety of colon-release propionyl-L-carnitine (PLC) in patients with mild-to-moderate UC receiving stable oral aminosalicylate or thiopurine therapy. METHODS In a multicentre, phase II, double-blind, parallel-group trial, patients were randomised to receive PLC 1 g/day, PLC 2 g/day or placebo. Main inclusion criteria were as follows: age 18-75; disease activity index (DAI) score 3-10 inclusive, be under oral stable treatment with aminosalicylate or thiopurine. The primary endpoint was clinical/endoscopic response, defined as a decrease in DAI score ≥ 3 points or remission, defined as a DAI score ≤ 2 with no individual sub-score > 1. RESULTS Of 121 patients who were randomised, 57 of 79 (72%) patients receiving PLC (combined 1 g and 2 g cohort) had a clinical/endoscopic response vs. 20 of 40 (50%) receiving placebo (P = 0.02). Specifically, in PLC 1 g/day group, 30 of 40 (75%) patients had clinical/endoscopic response (P = 0.02 vs. placebo) and 27 of 39 (69%) in the PLC 2 g/day group (P = 0.08 vs. placebo). Rates of remission were 22/40 (55%), 19/39 (49%), 14/40 (35%) in the PLC 1 g, PLC 2 g, and placebo groups, respectively. PLC had a similar safety profile to placebo; the most common adverse events were gastrointestinal. CONCLUSION Propionyl-L-carnitine 1 g/day should be investigated further as a co-treatment for mild-to-moderate ulcerative colitis (NCT-01026857).

Abstract
BACKGROUND Inflammatory bowel disease (IBD) frequently affects women during their reproductive years. Pregnancy outcome in women with IBD is well described, particularly in retrospective studies. AIM To evaluate the pregnancy outcome in patients with IBD in a prospective European multicentre case-control study. METHODS Inflammatory bowel disease pregnant women from 12 European countries were enrolled between January 2003 and December 2006 and matched (1:1) to non-IBD pregnant controls by age at conception and number of previous pregnancies. Data on pregnancy and newborn outcome, disease activity and therapy were prospectively collected every third month using a standard questionnaire. Logistic regression analysis with odds ratio was used for statistical analyses. P value<0.05 was considered significant. RESULTS A total of 332 pregnant women with IBD were included: 145 with Crohn's disease (CD) and 187 with ulcerative colitis (UC). Median age (range) at conception was 31 years (15-40) in CD and 31 (19-42) in UC patients. No statistically significant differences in frequency of abortions, preterm deliveries, caesarean sections, congenital abnormalities and birth weight were observed comparing CD and UC women with their non-IBD controls. In CD, older age was associated with congenital abnormalities and preterm delivery; smoking increased the risk of preterm delivery. For UC, older age and active disease were associated with low birth weight; while older age and combination therapy were risk factors for preterm delivery. CONCLUSION In this prospective case-control study, women with either Crohn's disease or ulcerative colitis have a similar pregnancy outcome when compared with a population of non-inflammatory bowel disease pregnant women.

Abstract
BACKGROUND AND AIM Mucosal healing (MH) after short-term medical treatment is being considered as an important step in the therapeutic work-up of inflammatory bowel disorder (IBD) patients due to the potential prognostic role of MH in predicting disease outcome. However, IBD patients are reluctant to be re-endoscoped during follow-up; therefore, there is a need for non-invasive alternative index of MH which can replace endoscopy in clinical practice. We evaluated bowel ultrasound (US) as a surrogate of colonoscopy in a series of consecutive patients with active ulcerative colitis (UC). PATIENTS AND METHODS 83 patients with moderate to severe UC requiring high-dose steroids were initially recruited; endoscopic severity of UC was graded 0-3 according to Baron score, and US severity was also graded 0-3 according to the colonic wall thickening and the presence of vascular signal at power Doppler. 74 patients responsive to steroids and then maintained on 5-ASA compounds were followed up with repeated colonoscopy and bowel US at 3, 9 and 15 months from entry. Concordance between clinical, endoscopic and US scores at various visits was determined by kappa statistics. Multiple unconditional logistic regression models were used to assess the predictivity of Truelove, Baron and US scores measured at 3 and 9 months on the development of a UC relapse (Baron score 2-3) at 15 months. RESULTS An inconsistent concordance was found over time between 0 and I Baron scores and Truelove score (weighted kappa between 0.38 and 0.94), with high and consistent concordance between 0 and I Baron scores and US scores (weighted kappa between 0.76 and 0.90). On logistic regression analysis, a moderate/severe Baron score, regardless of their Truelove score, at 3 months was associated with a high risk of endoscopic activity at 15 months (OR 5.2; 95% CI: 1.6-17.6); similarly, patients with severe US scores (2-3) at 3 months had a high risk of severe endoscopic activity at 15 months (OR 9.1; 95% CI: 2.5-33.5). DISCUSSION In expert hands bowel US may be used as a surrogate of colonoscopy in evaluating the response to high-dose steroids in severe forms of UC. US score after 3 months of steroid therapy accurately predicts clinical outcome of disease at 15 months.

Abstract
INTRODUCTION Colonoscopy is a necessary tool in the management of Crohn's disease, but the benefit achieved by the procedure is a matter of debate. In the present study we evaluate the clinical impact of performing colonoscopy in Crohn's disease patients. METHODS Consecutive patients with Crohn's disease undergoing colonoscopy were considered. The following issues were considered: appropriateness of indications; relevant findings able to change the management of the patients; the endoscopist's management decisions based on patient's clinical picture, i.e. increased, maintained or decreased treatment, compared with those selected after performing endoscopy. RESULTS 204 patients (116 male/88 female, mean age 41 years) were included. Colonoscopy was judged indicated in 52.9% cases, according to current guidelines. In 54% of patients, endoscopy revealed a significant lesion, and this rate was significantly lower for non-indicated procedures (25.9%, p<0.0001). The endoscopic findings were in disagreement with symptoms in about 25% of cases, but the impact of the endoscopic findings on the endoscopist's decision was likely to be very small without any differences between appropriate and inappropriate procedures. CONCLUSIONS Endoscopy is a potent tool in the management of Crohn's disease, if correctly used, but in the majority of cases a correct therapeutic decision may be established simply on the basis of clinical picture and non-invasive markers, whilst relevant endoscopic findings have a relatively low impact on the medical treatment.

Abstract
Crohn's disease and ulcerative colitis are lifelong diseases seen predominantly in the developed countries of the world. Whereas ulcerative colitis is a chronic inflammatory condition causing diffuse and continuous mucosal inflammation of the colon, Crohn's disease is a heterogeneous entity comprised of several different phenotypes, but can affect the entire gastrointestinal tract. A change in diagnosis from Crohn's disease to ulcerative colitis during the first year of illness occurs in about 10 % - 15 % of cases. Inflammatory bowel disease (IBD) restricted to the colon that cannot be characterized as either ulcerative colitis or Crohn's disease is termed IBD-unclassified (IBDU). The advent of capsule and both single- and double-balloon-assisted enteroscopy is revolutionizing small-bowel imaging and has major implications for diagnosis, classification, therapeutic decision making and outcomes in the management of IBD. The role of these investigations in the diagnosis and management of IBD, however, is unclear. This document sets out the current Consensus reached by a group of international experts in the fields of endoscopy and IBD at a meeting held in Brussels, 12-13th December 2008, organised jointly by the European Crohn's and Colitis Organisation (ECCO) and the Organisation Mondiale d'Endoscopie Digestive (OMED). The Consensus is grouped into seven sections: definitions and diagnosis; suspected Crohn's disease; established Crohn's disease; IBDU; ulcerative colitis (including ileal pouch-anal anastomosis [IPAA]); paediatric practice; and complications and unresolved questions. Consensus guideline statements are followed by comments on the evidence and opinion. Statements are intended to be read in context with qualifying comments and not read in isolation.

Abstract
Crohn's disease (CD) is associated with a higher type-1-helper T cell (Th1) cytokine expression, whereas ulcerative colitis (UC) appears to express a modified Th2 response. In addition to its classic role in calcium homeostasis, calcitriol, the hormonal active form of vitamin D, exerts immunoregulatory effects such as modulation of Th1/Th2 cytokines. Therefore, calcitriol administration could modify immune dysfunction in CD and UC. Nine patients with UC (M/F: 5/4; mean age 47 years, remission(R)/active(A) disease: 7/2), 8 patients with CD (M/F: 2/6; mean age 36, R/A 5/3) and 6 healthy controls (HC) (M/F: 3/3, mean age 4) were enrolled. Peripheral blood was collected after a drug-washout of 15 days and peripheral blood mononuclear cells were stimulated with mitogens alone or in the presence of physiological concentrations of calcitriol (100 pg/ml). Type 1 (IL-2, TNF-alpha, IFN-gamma) and type 2 (IL-10) cytokine production was assayed on supernatants by ELISA. Compared to HC, TNF-alpha production was significantly higher both in UC (p=0.0002) and CD (p=0.0001) patients, at baseline and after incubation with calcitriol (UC p=0.0003, CD p=0.0009). The effects of calcitriol incubation were: 1) reduced IFN-gamma (p=0.024) and increased IL-10 (p=0.06) production in UC patients; 2) reduced TNF-alpha production in CD (p=0.032); 3) no significant effects in HC. Calcitriol increased, albeit not significantly, IL-10 production in UC compared to CD patients (p=0.09). These results suggest an important modulatory role of vitamin D in the Th1/Th2 immune response. The observation that the effect of this modulation was different in CD compared to UC patients provides an interesting area of research into the pathogenesis and treatment of these inflammatory conditions.

Abstract
OBJECTIVES Autologous haematopoietic stem cell transplantation (HSCT) with CD34(+) cell selection has recently been used in the treatment of refractory Crohn's disease, showing good safety and promising efficacy. We investigated the safety and efficacy of HSCT with unselected peripheral blood stem cells (PBSCs) in moderate-severe refractory Crohn's disease. PATIENTS Four patients (three male, one female; age range 26-45 years) with active moderate-severe Crohn's disease (median Crohn's Disease Activity Index (CDAI) 319, range 272-345), refractory or intolerant to multiple drugs including infliximab, were enrolled. INTERVENTIONS Unselected PBSCs were collected after mobilisation with cyclophosphamide (CTX) 1.5 g/m2 and granulocyte-colony stimulating factor (G-CSF) 10 microg/kg. The conditioning regimen included CTX 50 mg/kg on days -5 to -2 and rabbit anti-thymocyte globulin (ATG) 2.5 mg/kg on days -4 to -2. MAIN OUTCOME MEASURES Primary endpoints were toxicity and clinical remission (CDAI<150) at 3 months. Secondary endpoints were clinical and endoscopic response at 3 months and toxicity, clinical and endoscopic remission at 12 months. RESULTS No improvement or slight deterioration was observed following mobilisation (median CDAI 339, range 258-404). At the third month, the primary endpoint of clinical remission was achieved in all patients, with a median CDAI of 91 (range 56-102), and complete endoscopic remission was achieved in 2/3 patients. After a median follow-up of 16.5 months, 3/4 patients maintained both clinical and endoscopic remission, despite withdrawal of all drugs, and complete fistula closure was observed in all affected patients. No deaths or life-threatening infection occurred. Unexpected adverse events included a perianal abscess after mobilisation in one patient, pleural and pericardial effusions in another and BK virus-related macrohaematuria in another, all rapidly resolved with conservative treatment. CONCLUSION Autologous HSCT with unselected PBSC appears to be safe and can induce and maintain remission in previously refractory Crohn's disease patients.

Abstract
Perianal fistulas and abscesses are common complications of Crohn's disease, affecting up to 50% of patients during their disease course. Accurate diagnosis and classification of perianal disease is crucial before and during treatment to plan an adequate approach for each patient and to avoid irreversible functional consequences. Although examination under anaesthesia has been considered the gold standard for diagnosis and classification of Crohn's disease perianal fistulas, taken alone it does not have perfect accuracy, stressing the need for concomitant or alternative, non-invasive, methods of evaluation. In this context, imaging modalities assessed for diagnosis, classification and monitoring of Crohn's disease perianal fistulas include pelvic magnetic resonance imaging, anorectal endoscopic ultrasonography, transcutaneous perianal ultrasound, fistulography and computed tomography. In particular, magnetic resonance imaging and endoscopic ultrasonography findings have shown the best accuracy, and the ability to influence therapeutic management of these patients. For transcutaneous perianal ultrasound too, good preliminary data have been reported. This paper reviews the available data on imaging methods for the management of perianal Crohn's disease.

Abstract
BACKGROUND Approximately 20% of patients with ulcerative colitis have a chronic active disease often requiring several courses of systemic steroids in order to achieve remission, but followed by relapse of symptoms during steroid tapering or soon after their discontinuation. Although short term control of symptoms can be achieved with steroid treatment, this pattern of drug response, known as steroid-dependency, leads to important complications of the treatment, while a significant proportion of patients requires colectomy. AIM To review the studies currently available specifically evaluating the management of steroid-dependent ulcerative colitis. RESULTS The clinical and biological mechanisms of steroid-dependency are not well understood compared with those determining steroid-refractoriness. Very few evidence-based data are available concerning the management of patients with steroid-dependent ulcerative colitis. The therapeutic role of aminosalicylates, thiopurines, methotrexate, infliximab, leukocyte apheresis and other drugs in the treatment of steroid-dependent ulcerative colitis are evaluated. CONCLUSIONS Outcomes of studies in steroid-refractory patients may not be applicable to steroid-dependency. Trials are needed to define the correct approaches and new strategies to ameliorate the therapy of steroid-dependent ulcerative colitis.

Abstract
BACKGROUND Several studies have evaluated the role of the multidrug resistance 1 gene (MDR1) polymorphism, which encodes the membrane-bound efflux transporter P-glycoprotein 170, in determining susceptibility to and disease behavior in inflammatory bowel disease (IBD), but with conflicting results. METHODS A total of 211 patients with Crohn's disease (CD), 97 patients with ulcerative colitis (UC), and 212 control subjects were investigated for the presence of MDR1 G2677T/A and C3435T polymorphisms. Genotype frequencies of CD and UC patients were compared to those observed in a control population. Genotype-phenotype correlations with major clinical features were also established and estimated risks (odds ratio [OR] with 95% confidence interval [CI]) for the mutations were calculated by a logistic regression analysis and multiple correspondent analysis. RESULTS No significant difference was observed for genotype frequencies for both MDR1 G2677T/A and C3435T polymorphisms on overall disease susceptibility for either CD or UC patients compared with control subjects. A significant association was found between the MDR1 C3435T polymorphism and patients with ileo-colonic CD (OR = 3.34; 95% CI: 1.34-8.27). Interestingly, a negative association was found between MDR1 C3435T polymorphism in patients with a positive family history for IBD (OR = 0.44; 95% CI: 0.20-0.95) and articular manifestations (OR = 0.29; 95% CI: 0.13-0.68). Both susceptible and protective effects were identified. No significant association between G2677T/A polymorphism and any specific subphenotypes was found, nor was there any association with subphenotypic categories of UC and both single nucleotide polymorphisms. CONCLUSIONS The results of our study suggest that MDR1 gene polymorphism could have a role in determining susceptibility to IBD. The variability of this possible effect in the several studies reported so far may be the indirect expression of the complex role played by the MDR1 gene and its product, P-glycoprotein 170, in the regulation of host-bacteria interactions and in the pathogenesis of IBD.

Abstract
Accurate staging of rectal and anal carcinoma is crucial for planning surgery and indicating adjuvant therapy. Although, computed tomography and magnetic resonance imaging are very sensitive in detecting metastatic disease, the local staging of rectal cancer with these techniques has been disappointing. Endorectal ultrasound (ERUS) and anal endosonography (AE) remain the most accurate methods for staging rectal and anal cancer. Anal endosonography is also of value in evaluating perianal sepsis: it can assist the surgeon in planning the surgical strategy by delineating the anatomy of fistula tracts, and can aid in puncturing abscesses in the operating room. Continued research and development has made the instrumentation for ERUS and AE more accurate and user-friendly. New techniques that have contributed significantly to the evolution of ERUS include three-dimensional ERUS, high-frequency miniprobes, transrectal ultrasound-guided biopsy techniques and hydrogen peroxide-enhanced endosonography. Further improvements can be expected from contrast enhancement with microbubbles and colour Doppler imaging. In this new millennium, new developments in ERUS and anal endosonography, such as tri-dimensional ERUS and anal endosonography and radial electronic probing, widen the role of ERUS in the staging of rectal and anal carcinoma, as well as for perianal inflammatory conditions.

Abstract
BACKGROUND AND AIMS There are limited evidence based data concerning the use of azathioprine in ulcerative colitis. We aimed to compare the efficacy of azathioprine and oral 5-aminosalicylic acid in inducing remission of steroid dependent ulcerative colitis. METHODS Seventy two patients with steroid dependent ulcerative colitis were admitted to this investigator-blind study. Steroid dependence was defined as a requirement for steroid therapy > or =10 mg/day during the preceding six months, with at least two attempts to discontinue the medication. The disease had to be clinically and endoscopically active at study entry, and all patients were taking systemic prednisolone (40 mg/day). Patients were randomised to receive azathioprine 2 mg/kg/day or oral 5-aminosalicylic acid 3.2 g/day, for a six month follow up period. The outcome of the treatment was defined as (1) success, indicating induction of clinical and endoscopic remission and steroid discontinuation, or (2) failure, indicating the absence of clinical and endoscopic remission and therefore the need for at least one further cycle of systemic steroids to control symptoms, apart from the initial one, or colectomy. RESULTS Significantly more patients in the azathioprine than in the 5-aminosalicylic acid group had clinical and endoscopic remission, and discontinued steroid therapy, both in the intention to treat (azathioprine v 5-aminosalicylic acid: 19/36 patients (53%) v 7/36 (21%); odds ratio (OR) 4.78 (95% confidence interval (CI) 1.57-14.5)) and per protocol (azathioprine v 5-aminosalicylic acid: 19/33 patients (58%) v 7/34 (21%); OR 5.26 (95% CI 1.59-18.1)) analysis. CONCLUSIONS Azathioprine is significantly more effective than 5-aminosalicylic acid in inducing clinical and endoscopic remission and avoiding steroid requirement in the treatment of steroid dependent ulcerative colitis.

Abstract
BACKGROUND The potential clinical implications of autoimmunity during treatment with infliximab are unclear. AIM To determine the frequency and correlation of autoantibody formation in patients with Crohn's disease treated with infliximab in a routine clinical setting. METHODS Sixty-three patients with refractory/inflammatory (31) and/or fistulising Crohn's disease (32), received an infliximab infusion at a dose 5 mg/kg in weeks 0, 2 and 6, and were evaluated for the development of antinuclear, anti-double-stranded DNA, anti-Sm, anti-RNP, anti-SSA, anti-SSB and antihistone antibodies. The correlates with pharmacological treatments, the response to infliximab and adverse events were evaluated. RESULTS Antinuclear antibodies were found in five of the 63 patients (8%) at baseline and in 26 (42%) after 10 weeks (P < 0.001). Of the 26 antinuclear antibody-positive patients who were further subtyped, nine of 63 (17%) had anti-double-stranded DNA (P = 0.003), and 1.5% were extractable nuclear antigen (ENA) and antihistone-positive. Five patients were initially positive for anticardiolipin antibodies and two more patients became positive during infliximab treatment. New autoantibody formation was more frequent in the patients with inflammatory/refractory disease than in those with fistulising disease (17 vs. 7; P = 0.02). One patient developed drug-induced lupus without major organ damage. CONCLUSIONS Autoantibody formation occurs in 42% of patients (8% of these patients were positive before infliximab treatment) with Crohn's disease receiving induction treatment with infliximab, but the clinical significance of this remains to be determined.

Abstract
BACKGROUND Hepatitis C virus infection is more common in patients with inflammatory bowel disease than in general population. Limited data are available as to the safety and efficacy of alpha-interferon therapy for chronic active hepatitis C in patients with concomitant inflammatory bowel disease. AIM To evaluate the efficacy and safety of alpha-interferon monotherapy in patients with chronic active hepatitis C and inactive or mildly active inflammatory bowel disease. METHODS A total of 513 consecutive inflammatory bowel disease patients at a single centre were tested for antibodies to hepatitis C virus (anti-hepatitis C virus) between 1995 and 2000. Twenty-one patients had detectable anti-hepatitis C virus Ab and were hepatitis C virus-RNA positive with histologically proved chronic active hepatitis. Each of these patients, whose inflammatory bowel disease was in clinical remission or mildly active, was sex- and age-matched to three controls with similar histological grade and stage of chronic hepatitis C virus but without inflammatory bowel disease; and all were treated with human leucocyte alpha-interferon 6 million units given thrice weekly for 12 months. Responses to treatment were classified as follows: complete response--persistently normal alanine aminotransferase and viral clearance (hepatitis C virus-RNA-ve) at the end-of-treatment, incomplete response--alanine aminotransferase normalization without viral clearance (hepatitis C virus-RNA+ve), and sustained response--alanine aminotransferase normalization and hepatitis C virus clearance 12 months after the end-of-treatment. RESULTS Twenty-one patients with chronic active hepatitis C and inflammatory bowel disease (10 with Crohn's disease and 11 with ulcerative colitis) and 63 sex- and age-matched controls with chronic hepatitis C virus alone received alpha-interferon monotherapy. Response rates to interferon were similar for inflammatory bowel disease patients compared with controls [CR 42% vs. 35% and SR 24% vs. 18% (P, not significant), respectively]. None of the 21 inflammatory bowel disease patients had severe adverse effects and the mild ones observed were comparable with those seen in the control group. No patients developed an inflammatory bowel disease relapse during the interferon treatment period or in the 12 months thereafter. CONCLUSIONS The biochemical and virological response to a 12-month human leucocyte alpha-interferon treatment in patients with chronic active hepatitis C are similar to that observed in matched controls with chronic hepatitis C virus without inflammatory bowel disease. Adverse effects are similar in both groups of patients and unrelated to the underlying inflammatory bowel condition. This provides hepatologists with evidence that alpha-interferon can be safely administered to patients with chronic hepatitis C virus and inflammatory bowel disease provided that the inflammatory bowel condition is in clinical remission.

Abstract
OBJECTIVE To determine the prevalence of cytomegalovirus infection in patients with steroid-refractory ulcerative colitis who required colonic resection, and to assess its possible association with the use of immunosuppressive and steroid treatment and outcome after colectomy. PATIENTS AND METHODS The study included surgical specimens and related pre-operative endoscopic biopsy specimens of 77 consecutive ulcerative colitis patients (34 females) who underwent colectomy because of intractable steroid-refractory ulcerative colitis (55 patients), toxic megacolon (6 patients), dysplasia or cancer (7 patients) or loss of function of the colon (9 patients). Clinical features and current and past treatments were analysed. Haematoxylin and eosin and specific immunohistochemical staining for cytomegalovirus were used to detect inclusion bodies in all specimens. RESULTS Cytomegalovirus infection was found in 15 of 55 steroid-refractory ulcerative colitis patients (27.3%) and in 2 of 22 non-refractory patients (9.1%) (p=0.123). Only six patients had positive staining for cytomegalovirus in pre-operative endoscopic biopsy specimens. Detection of cytomegalovirus inclusion in biopsy specimens was not related to the number of biopsies or to time that had elapsed since colonoscopy and index surgery. Cytomegalovirus-positive patients were more likely to be on systemic corticosteroids (p=0.03). In contrast, current use and duration of immunosuppressive treatment, number of steroid cycles since diagnosis and in the last year, as well as chronic use of steroid in the last year were not significantly related to cytomegalovirus infection. Cytomegalovirus-positive patients did not receive antiviral therapy following proctocolectomy but did not show endoscopic or histological cytomegalovirus reactivation in the ileo-anal pouch and in the remaining bowel. CONCLUSIONS Cytomegalovirus infection is frequently found in surgical specimens of patients with steroid-refractory ulcerative colitis and is more likely in patients on corticosteroid treatment. Cytomegalovirus infection is frequently unrecognised in pre-operative biopsy specimens, thus raising concerns about the accuracy of the available diagnostic tools. Unrecognised and untreated cytomegalovirus infection does not affect the outcome of ulcerative colitis patients following proctocolectomy.

Abstract
INTRODUCTION Despite the explosion of biological therapies, the old immunosuppressants continue to play a pivotal role in the management of inflammatory bowel diseases. AIM To assess the appropriateness of immunosuppressants-azathioprine, 6-mercaptopurine, methotrexate, cyclosporine A, tacrolimus (FK506), mycophenolate mofetil and thalidomide-in the treatment of inflammatory bowel disease by using RAND/University of California Appropriateness Method. METHODS The RAND method consists of a combination of evidence from the literature and experts' opinions. Appropriateness has been defined to mean that the expected health benefit exceeds the expected negative consequences by a sufficiently wide margin. A panel of 10 experts from the Italian Group for Inflammatory Bowel Disease has rated, in two rounds, on a scale from 1 to 9, the appropriateness of each indication selected by the Promoter Centre, on the basis of their own clinical experience. An indication was considered appropriate if the median of the panelists' ratings fell within the area 7-9, inappropriate in the area 1-3 and uncertain in the area 4-6. A total of 2781 indications were grouped into 13 categories (mild to moderate Crohn's disease; severe Crohn's disease; fistulizing Crohn's disease; steroid-dependant and -resistant Crohn's disease; maintenance of remission induced by medical treatment in Crohn's disease; maintenance of remission induced by surgery in Crohn's disease; mild to moderate ulcerative colitis; severe ulcerative colitis; steroid-dependant and -resistant ulcerative colitis; maintenance of remission induced by medical treatment in ulcerative colitis; extra-intestinal manifestations in inflammatory bowel disease; pregnancy and inflammatory bowel disease; azathioprine-resistant or -intolerant inflammatory bowel disease patients). RESULTS Of the 2781 scenarios, 212 (7.6%) were rated appropriate, 645 (23.2%) uncertain and 1924 (69.2%) inappropriate. The most relevant results were: in steroid-dependant or -resistant Crohn's disease, azathioprine, 6-mercaptopurine and methotrexate were defined as appropriate in 25 (86.2%) and 14 (48.3%) of the 29 scenarios respectively; in Crohn's disease, azathioprine and 6-mercaptopurine were defined as appropriate combined with Infliximab (bridge therapy); in steroid-dependant or -resistant ulcerative colitis, azathioprine and 6-mercaptopurine were defined as appropriate in 45 (77.6%) out of 58 scenarios, while methotrexate was defined appropriate only after previous azathioprine failure; in severe ulcerative colitis, cyclosporine A was defined as appropriate only after previous failure with steroids; in azathioprine-intolerant or -resistant inflammatory bowel disease patients, methotrexate was appropriate in 20 (66.7%) out of 30 scenarios; it is inappropriate to stop azathioprine treatment before conception in the presence of active disease. The use of FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate or uncertain. CONCLUSIONS Results of this study show that only azathioprine, 6-mercaptopurine and methotrexate are appropriate in the treatment of inflammatory bowel diseases. Cyclosporine A was found to be appropriate only in severe ulcerative colitis after the failure of steroids. FK506, mycophenolate mofetil and Thalidomide resulted as inappropriate but experience with these agents is somewhat limited.

Abstract
BACKGROUND Three variants of the NOD2/CARD15 gene are strongly associated with susceptibility to Crohn's disease; however, striking racial and geographic differences of their frequency have been described. AIMS We have compared the allele frequencies of familial cases of Crohn's disease recruited in a multicentre study across Italy, in order to disclose possible geographic heterogeneity. Moreover, we also compared the allele frequencies in sporadic cases of Crohn's disease and healthy controls from Southern Italy with those reported in other two populations from Central and Northern Italy. SUBJECTS AND METHODS A total of 731 subjects were genotyped for the polymorphism of three main variants (R702W, G908R and 1007 fs): 152 patients were familial cases of Crohn's disease, 183 were healthy first-degree relatives, 180 were sporadic cases of Crohn's disease, and 216 were unrelated healthy subjects. RESULTS The frequency of the frameshift mutation (1007 fs) was significantly higher in both familial and sporadic cases of Crohn's disease (P = 0.000001), and healthy first-degree relatives (P = 0.0001) compared to controls. At least one risk allele was found in 44% of familial Crohn's disease patients, compared to 7% of healthy controls (OR = 4; CI = 2-6.5). Two risk alleles were found in 14% of familial Crohn's disease, compared to less than 1% of controls (OR = 26: CI = 4-129). CONCLUSIONS Our data confirm the strong correlation between the 1007 fs variant and Crohn's disease, in both familial and sporadic cases. Moreover, no significant difference of allele frequencies was detected in familial cases, sporadic cases and healthy controls among different geographic areas of Italy.

Abstract
The use of ultrasound in Crohns disease has a recent history. This method is useful in various situations like: the diagnosis of the disease, the diagnosis of intra-abdominal complications and the follow-up of the operated patient. Moreover, thanks to its practicality of use, ripetibility and accuracy, ultrasounds can represent a first line diagnostic instrument for Crohns disease both in elective and emergency conditions. The authors, in this paper, consider its usefulness and various aspects in these conditions.

Abstract
An 18-year-old male patient was under treatment with infliximab at a dose of 5 mg/kg at Weeks 0, 2 and 6 for refractory Crohn's disease. In June 2002, the patient was admitted to the Outpatient Clinic of the Rheumatology Unit for arthralgia affecting the small joints, non-pruritic crops of purple skin lesions and malar rash in the face. Serum antinuclear antibodies were positive (1:640 speckled pattern), and anti-double-stranded DNA was positive (1:80); moreover, positivity of anti-extractable nuclear antigen was observed. Antihistone antibodies, lupus anticoagulant and anticardiolipin antibodies were negative. A diagnosis of infliximab-induced lupus was made and the drug treatment was withdrawn. However, 3 months after withdrawal of treatment, the patient still showed clinical and laboratory symptoms of systemic lupus erythematosus. After 6 months of treatment, systemic lupus erythematosus-related symptoms disappeared and anti-double-stranded DNA returned to normal. The patient is currently under treatment with prednisone 20 mg/day for systemic lupus erythematosus and with oral mesalazine 2.4 mg/day for Crohn's disease. Treatment with infliximab is known to produce an increase of autoantibodies (antinuclear antibodies, anti-double-stranded DNA), but not clinical disease. This is the first case, to our knowledge, of onset of prolonged infliximab-induced lupus.

Abstract
Crohns Disease (CD) is a chronic intestinal inflammatory disease of unknown origins that cannot be definitely resolved with surgical intervention. Therefore, pharmacologic therapies are of great importance both in preventing relapses and by determining remissions. In this paper the authors analyse the different drugs available for the treatment of Crohns disease, and focus on their efficacy and tollerability.

Abstract
AIM To establish whether intestinal ultrasound, clinical or biochemical indices of activity can assess histological features of ileal stenosis in Crohn's disease. METHODS In 43 patients undergoing surgery for a single ileal stenosis, clinical and biochemical parameters, as well as intestinal ultrasound, were assessed prior to surgery. The echo pattern of thickened bowel segments at the site of stenosis was classified as hypoechoic, stratified or mixed (segments with/without stratification). During surgery, stenoses were identified, resected and then histologically examined using standardized criteria. RESULTS Clinical and biochemical indices of activity showed an overall weak positive correlation with histological inflammatory parameters and a negative correlation with fibrosis. The intestinal ultrasound echo pattern at the stenosis site was stratified in 25 patients, hypoechoic in 14 and mixed in four. Stenoses characterized by a stratified echo pattern showed a significantly higher degree of fibrosis, those characterized by hypoechoic echo pattern showed a higher degree of inflammation, while stenoses with a mixed echo pattern showed high degrees of both fibrosis and inflammation. CONCLUSION Ultrasound and, to a lesser degree, clinical and laboratory indices discriminate between inflammatory and fibrotic ileal stenoses complicating Crohn's disease, thus allowing appropriate medical and/or surgical treatment to be defined.

Abstract
BACKGROUND AND AIMS The efficacy of azathioprine in the treatment of chronic active Crohn's disease is well established. However, this drug has a long onset of action. Methotrexate has also been shown to be effective in chronic active Crohn's disease. The aim of this study was to evaluate the efficacy and safety of methotrexate in comparison with azathioprine, and to establish whether methotrexate has a shorter onset of action in this setting. METHODS Patients with chronic active Crohn's disease were admitted to this investigator-blind study. Chronicity was defined as the need for steroid therapy of > or = 10 mg/day for at least 4 months during the preceding 12 months, with at least one attempt to discontinue treatment. The disease had to be clinically active at entry, with a Crohn's Disease Activity Index of > or = 200. Six patients treated with azathioprine and methotrexate, respectively, were found to have enterocutaneous and perianal fistulas. At entry, all patients received prednisolone (40 mg once a day) which was tapered over a period of 12 weeks unless their clinical condition deteriorated. All patients were randomised to receive i.v. methotrexate 25 mg/week, or oral azathioprine 2 mg/kg per day, for a 6-month follow-up period. After the first 3 months, methotrexate was switched to oral administration maintaining the same dose. The primary efficacy outcome considered was the proportion of patients entering first remission after 3 and 6 months of therapy. Clinical remission was defined as the lack of need for steroid treatment and a Crohn's Disease Activity Index score of < or = 150 points at each scheduled visit. RESULTS In the 54 patients (26 F, 28 M, mean age 34 years, range 18-60) randomly assigned to methotrexate (n=27) or azathioprine (n=27), no statistically significant difference was found between the two treatment regimens with respect to remission rate after 3 (methotrexate 44%, azathioprine 33%, p=0.28, (95% CI, 0.369-0.147), and 6 months (methotrexate 56%, azathioprine 63%, p=0.39, 95% CI, 0.187-0.335), respectively. Six patients withdrew from therapy due to adverse events: 3/27 (11%) in methotrexate and 3/27 (11%) in azathioprine. Drug-related adverse events (asthenia, nausea and vomiting) that did not require withdrawal from therapy were more frequent in the methotrexate group (azathioprine: 2/27 (7%); methotrexate: 12/27 (44%), p=0.00009). The frequency of these adverse events was comparable during the intravenous or oral administration of the drug. CONCLUSIONS This study confirms that methotrexate is effective in inducing remission in patients with chronic active Crohn's disease, therapeutic efficacy being comparable, but not faster, than that of azathioprine.

Abstract
Despite all the advances in our understanding of the pathophysiology of inflammatory bowel disease (IBD), we do not know the cause. Some of the most recently available data have been discussed here and yet it is now becoming increasingly accepted that immunogenetics play an important role in the predisposition, modulation, and perpetuation of IBD. The mucosal immune system is the central effector of intestinal inflammation and injury, with cytokines playing a central role in modulating inflammation. The role of intestinal milium, and enteric flora in particular, appears to be of greater significance than previously held. A review is made of the main areas of research exploring the mechanisms more intimately associated with the development of IBD, providing advances in the agents currently used, and identifying a host of new therapeutic agents potentially interacting with or interrupting specific targets in the genesis of IBD.

Abstract
BACKGROUND The association of oral 5-aminosalicylic acid (mesalazine) and enema is effective in treatment of mild-moderate forms of ulcerative colitis. However no study has been aimed at determining optimal duration of this association in active ulcerative colitis. AIM To determine whether longer duration of therapy: 1. increases the rate of patients achieving remission, and 2. reduces relapse rate during the maintenance period in patients in remission. PATIENTS AND METHODS A total of 149 patients, (89 male, 60 female), were randomly assigned to a regimen with 5-aminosalicylic acid tablets 2.4 g/day associated with 5-aminosalycilic enema 2 g/day for a 4-week (n = 73) or 8-week regimen (n = 76). After this acute therapy, patients were submitted to clinical, endoscopic and histological examinations and those in remission were assigned to a follow-up (maintenance) period with oral mesalazine alone at a dosage of 1.2 g/day. A clinical visit, including laboratory tests, at 6 months and an endoscopic-histological control at 12 months were carried out to exclude symptoms and endoscopic-histological signs of activity. Relapse of disease, i.e., presence of clinical symptoms or abnormal laboratory tests, was confirmed by endoscopy and histology. RESULTS At end of acute phase, clinical, endoscopic and histological remission was comparable in the two groups: 42/76 (55%), in the 4-week, and 47/73 patients (64%), in the 8-week regimen. No difference was found stratifying patients according to extension of disease. Of these 89 patients in remission, 75 (34 from 4-week regimen; 41 from 8-week regimen) completed 12 months' follow-up. At end of follow-up, a similar percentage of patients in the 4-week regimen (50%) and 8-week regimen (51%) were still in remission. No significant difference between cumulative relapse rates of the two groups was found. Stratifying patients according to extension of disease, in the 8-week regimen group, those with left-sided colitis showed a higher remission rate than that of patients with diffuse colitis (66% versus 35%, p < 0.05). All regimens were well tolerated by most patients during the entire study period. CONCLUSIONS An additional 4 weeks of topical treatment does not increase the remission rate in patients with mild-moderate active ulcerative colitis but seems to reduce the probability of relapse in patients with left-sided colitis.

Abstract
BACKGROUND Efficacy of infliximab in treatment of patients with moderate-to-severe refractory and fistulizing Crohn's disease has been shown in controlled clinical trials. Moreover, audit data from North America and North Europe have confirmed efficacy in clinical practice comparable to that in clinical trials. AIM To report clinical experience using infliximab in treatment of Crohn's disease in Italy, comparing efficacy and safety with those reported in clinical trials and other published series. PATIENTS AND METHODS The study population comprised 63 patients (31 males and 32 females, median age 33 years) treated with infliximab for refractory/inflammatory (31 patients) and/or fistulizing Crohn's disease (32 patients). All patients received an infusion of infliximab at a dose of 5 mg/kg at weeks 0, 2 and 6. After the first infusion, clinical and laboratory assessments were repeated at weeks 2, 6 and 10. For refractory inflammatory Crohn's disease, clinical remission was defined as a Crohn's Disease Activity Index of < or = 150 at each scheduled visit, clinical response as a reduction in the Crohn's Disease Activity Index score of > or = 70 points in comparison to baseline. For fistulizing Crohn's disease, a complete response was defined as closure of any draining fistulae at week 10. A fistula was defined as closed when it no longer drained despite gentle finger pressure. A partial response was defined as reduction in number, size or drainage of fistulae, at the same visit. RESULTS According to an intention-to-treat evaluation on the 31 patients with refractory/inflammatory Crohn's disease, at week 2, 42.5% (14 patients) had a clinical response and 31.3% of patients (10 patients) were in clinical remission. At week 10 (4 weeks after the end of third infusion), 80.6% (25 patients) had a clinical response and 71% (22 patients) were in clinical remission and 14/19 (74%) had discontinued steroid treatment. Of the 32 patients with fistulizing Crohn's Disease, 15 (46.9%) had a complete response, 8 (25%) a partial response, and 9 (28.1%) no response at week 10 check-up. The incidence of side-effects was low (16%) and not influenced by concurrent immunomodulatory therapy. CONCLUSION The present experience with infliximab in clinical practice confirms its efficacy, in particular in inflammatory/refractory Crohn's disease and its safety, at least, in short-term follow-up.

Abstract
OBJECTIVE In Crohn's disease (CD), the relationship between genetic predisposition and smoking has not been well defined. The aim of this study was to compare the smoking habits at the time of the diagnosis of CD patients having familial occurrence of inflammatory bowel disease (IBD) with those of some control groups. METHODS In a multicenter study, 136 CD patients with a relative with IBD, 272 healthy controls matched for sex and age, 500 CD patients without familial occurrence of IBD, and 84 ulcerative colitis patients (UC) with familial occurrence of IBD were personally interviewed about their smoking habits. In addition, data for 35 healthy siblings of patients with familial CD were collected by interviewing the patients' relatives. RESULTS The prevalence of smokers was found significantly higher in CD patients with a family history for IBD than in healthy controls and in familial UC patients (OR 2.28 CI 1.5-3.48 and OR 5.81 CI 3.15-10.75, respectively). No significant difference was found either in the percentage of smokers or in the number of cigarettes smoked per day between familial and sporadic CD patients. Among all siblings of CD patients, 72% of affected siblings and 34% of healthy siblings were smokers, concordant with their relatives. CONCLUSIONS In CD patients with familial occurrence of IBD, the percentage of smokers is elevated. It is possible that in a genetically predisposed population, smoking could be an important environmental factor in determining CD or expressing this disease instead of UC.
