Rates of Adverse Events in Patients With Ulcerative Colitis Undergoing Colectomy During Treatment With Tofacitinib vs Biologics: A Multicenter Observational Study.

INTRODUCTION: Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics. METHODS: A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exposed to tofacitinib or a biologic before surgery. Primary outcome was the occurrence of any complication within 30 (early) and 90 (late) days after surgery. Secondary outcomes were the occurrence of infections, sepsis, surgical site complications, venous thromboembolic events (VTE), hospital readmissions, and redo surgery within the same timepoints. RESULTS: Three hundred one patients (64 tofacitinib, 162 anti-tumor necrosis factor-α agents, 54 vedolizumab, and 21 ustekinumab) were included. No significant differences were reported in any outcome, except for a higher rate of early VTE with anti-tumor necrosis factor-α agents ( P = 0.047) and of late VTE with vedolizumab ( P = 0.03). In the multivariate analysis, drug class was not associated with a higher risk of any early and late complications. Urgent colectomy increased the risk of any early (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.06-3.48) complications, early hospital readmission (OR 4.79, 95% CI 1.12-20.58), and early redo surgery (OR 7.49, 95% CI 1.17-47.85). A high steroid dose increased the risk of any early complications (OR 1.96, 95% CI 1.08-3.57), early surgical site complications (OR 2.03, 95% CI 1.01-4.09), and early redo surgery (OR 7.52, 95% CI 1.42-39.82). Laparoscopic surgery decreased the risk of any early complications (OR 0.54, 95% CI 0.29-1.00), early infections (OR 0.39, 95% CI 0.18-0.85), and late hospital readmissions (OR 0.34, 95% CI 0.12-1.00). DISCUSSION: Preoperative tofacitinib treatment demonstrated a postoperative safety profile comparable with biologics in patients with UC undergoing colectomy.

Autoimmune Pancreatitis in Patients with Inflammatory Bowel Disease: A Real-World Multicentre Collaborative ECCO CONFER Study.

BACKGROUND: Autoimmune pancreatitis [AIP] is rarely associated with inflammatory bowel disease [IBD]. The long-term outcomes of AIP and IBD in patients with coexisting AIP-IBD and predictors of complicated AIP course have rarely been reported. METHODS: An ECCO COllaborative Network For Exceptionally Rare case reports project [ECCO-CONFER] collected cases of AIP diagnosed in patients with IBD. Complicated AIP was defined as a composite of endocrine and/or exocrine pancreatic insufficiency, and/or pancreatic cancer. We explored factors associated with complicated AIP in IBD. RESULTS: We included 96 patients [53% males, 79% ulcerative colitis, 72% type 2 AIP, age at AIP diagnosis 35 ±â€…16 years]. The majority of Crohn's disease [CD] cases [78%] had colonic/ileocolonic involvement. In 59%, IBD preceded AIP diagnosis, whereas 18% were diagnosed simultaneously. Advanced therapy to control IBD was used in 61% and 17% underwent IBD-related surgery. In total, 82% of patients were treated with steroids for AIP, the majority of whom [91%] responded to a single course of treatment. During a mean follow-up of 7 years, AIP complications occurred in 25/96 [26%] individuals. In a multivariate model, older age at AIP diagnosis was associated with a complicated AIP course (odds ratio [OR] = 1.05, p = 0.008), whereas family history of IBD [OR = 0.1, p = 0.03], and CD diagnosis [OR = 0.2, p = 0.04] decreased the risk of AIP complications. No IBD- or AIP-related deaths occurred. CONCLUSIONS: In this large international cohort of patients with concomitant AIP-IBD, most patients have type 2 AIP and colonic IBD. AIP course is relatively benign and long-term outcomes are favourable, but one-quarter develop pancreatic complications. Age, familial history of IBD, and CD may predict uncomplicated AIP course.

Main factors influencing long-term outcomes of liver transplantation in 2022.

Liver transplant (LT) outcomes have markedly improved in the recent decades, even if long-term morbidity and mortality are still considerable. Most of late deaths are independent from graft function and different comorbidities, including complications of metabolic syndrome and de novo neoplasms, seem to play a key role in determining long-term outcomes in LT recipients. This review discusses the main factors associated with late mortality and suggests possible strategies to improve long-term management and follow-up after liver transplantation. In particular, the reduction of drug toxicity, the use of tools to identify high-risk patients, and setting up a multidisciplinary team also for long-term management of LT recipients may further improve survival after liver transplantation.

Comparison of two strategies for the management of postoperative recurrence in Crohn's disease patients with one clinical risk factor: A multicentre IG-IBD study.

BACKGROUND: The management of postoperative recurrence (POR) in Crohn's disease (CD) after ileo-colonic resection is a highly debated topic. Prophylactic immunosuppression after surgery is currently recommended in the presence of at least one clinical risk factor. OBJECTIVE: Our aim was to determine whether early immunosuppression can be avoided and guided by endoscopy in CD patients with only one risk factor. METHODS: CD patients with only one risk factor for POR, including previous intestinal resection, extensive small intestine resection (>50 cm), fistulising phenotype, history of perianal disease, and active smoking, were retrospectively included. Two groups were formed based on whether immunosuppression was started immediately after surgery ("prophylaxis group") or guided by endoscopy ("endoscopy-driven group"). Primary endpoints were rates of any endoscopic recurrence (Rutgeerts ≥ i2a) and severe endoscopic recurrence (i4) within 12 months after surgery. Secondary outcomes were clinical recurrence rates at 6, 12 and 24 months after surgery. RESULTS: A total of 195 patients were enroled, of whom 61 (31.3%) received immunoprophylaxis. No differences between immunoprophylaxis and the endoscopy-driven approach were found regarding any endoscopic recurrence (36.1% vs. 45.5%, respectively, p = 0.10) and severe endoscopic recurrence (9.8% vs. 15.7%, respectively, p = 0.15) at the first endoscopic evaluation. Clinical recurrence rates were also not statistically different (p = 0.43, p = 0.09, and p = 0.63 at 6, 12, and 24 months, respectively). CONCLUSIONS: In operated CD patients with only one risk factor for POR, immediate immunoprophylaxis does not decrease the rate of early clinical and endoscopic recurrence. Prospective studies are needed to confirm our results.

Branch duct-intraductal papillary mucinous neoplasms (BD-IPMNs): an MRI-based radiomic model to determine the malignant degeneration potential.

BACKGROUND: Branch duct-intraductal papillary mucinous neoplasms (BD-IPMNs) are the most common pancreatic cystic tumors and have a low risk of malignant transformation. Features able to early identify high-risk BD-IPMNs are lacking, and guidelines currently rely on the occurrence of worrisome features (WF) and high-risk stigmata (HRS). AIM: In our study, we aimed to use a magnetic resonance imaging (MRI) radiomic model to identify features linked to a higher risk of malignant degeneration, and whether these appear before the occurrence of WF and HRS. METHODS: We retrospectively evaluated adult patients with a known BD-IPMN who had had at least two contrast-enhanced MRI studies at our center and a 24-month minimum follow-up time. MRI acquisition protocol for the two examinations included pre- and post-contrast phases and diffusion-weighted imaging (DWI)/apparent diffusion coefficient (ADC) map. Patients were divided into two groups according to the development of WF or HRS at the end of the follow-up (Group 0 = no WF or HRS; Group 1 = WF or HRS). We segmented the MRI images and quantitative features were extracted and compared between the two groups. Features that showed significant differences (SF) were then included in a LASSO regression method to build a radiomic-based predictive model. RESULTS: We included 50 patients: 31 in Group 0 and 19 in Group 1. No patients in this cohort developed HRS. At baseline, 47, 67, 38, and 68 SF were identified for pre-contrast T1-weighted (T1-W) sequence, post-contrast T1-W sequence, T2-weighted (T2- W) sequence, and ADC map, respectively. At the end of follow-up, we found 69, 78, 53, and 91 SF, respectively. The radiomic-based predictive model identified 16 SF: more particularly, 5 SF for pre-contrast T1-W sequence, 6 for post-contrast T1-W sequence, 3 for T2-W sequence, and 2 for ADC. CONCLUSION: We identified radiomic features that correlate significantly with WF in patients with BD-IPMNs undergoing contrast-enhanced MRI. Our MRI-based radiomic model can predict the occurrence of WF.

ECCO Topical Review on Biological Treatment Cycles in Crohn's Disease.

There are now a growing number of licensed biological therapies for patients with Crohn's disease. However, there can be significant costs associated with long-term maintenance treatment, as well as some concerns about potential side-effects. As a result, there has been increasing interest in elective biological treatment discontinuation in selected patients, after a sustained period of remission. Following discontinuation, in cases of relapse, evidence to date has suggested that remission may often be regained by re-treatment with the same biological agent. Therefore, a concept has emerged in which cycles of biological therapy might be used. If this treatment strategy were to be applied in a subgroup of patients at low risk of relapse, cycling might allow a substantial number of patients to have a lower, overall therapeutic burden-ensuring decreased exposure to biological therapy but still enabling appropriate disease control. Currently, there remains uncertainty about the benefit-risk balance for using cycles of biological treatment for patients with Crohn's disease. Accordingly, an expert panel was convened by the European Crohn's and Colitis Organisation [ECCO] to review the published literature and agree a series of consensus practice points. The panel aimed to provide evidence-based guidance on multiple aspects of biological treatment discontinuation and cycling, including the risk of relapse after elective treatment discontinuation, predictors of probable relapse or remission, safety, patient preferences, and pharmacoeconomic aspects. Crucially, discussions about biological treatment discontinuation and cycling should be individualized, to enable shared decision-making by patients with their clinicians.

MiRNA-Based Therapies for the Treatment of Inflammatory Bowel Disease: What Are We Still Missing?

Micro-RNAs (miRNAs) are noncoding RNAs usually 24-30 nucleotides long that play a central role in epigenetic mechanisms of inflammatory diseases and cancers. Recently, several studies have assessed the involvement of miRNAs in the pathogenesis of inflammatory bowel disease (IBD) and colitis-associated neoplasia. Particularly, it has been shown that many members of miRNAs family are involved in the pathways of inflammation and fibrogenesis of IBD; therefore, their use as inflammatory and fibrosis biomarkers has been postulated. In light of these results, the role of miRNAs in IBD therapy has been proposed and is currently under investigation with many in vitro and in vivo studies, murine models, and a phase 2a trial. The accumulating data have pushed miRNA-based therapy closer to clinical practice, although many open questions remain. With this systematic review, we discuss the current knowledge about the therapeutic effects of miRNAs mimicking and inhibition, and we explore the new potential targets of miRNA family for the treatment of inflammation and fibrosis in IBD.

Micro-RNAs are involved in the pathogenesis of IBD, both during inflammation and fibrosis. Upregulation or downregulation of these RNA targets may be a therapeutic option, but several pathways are still under investigation. This review describes the main findings in the field and speculates on potential future implications.

Multidisciplinary Perinatal Care in IBD.

BACKGROUND AND AIMS: Patients with inflammatory bowel disease [IBD] are often affected during their reproductive years and may have many perinatal queries that require the comprehensive perspectives of a multidisciplinary team [MDT]. The purpose of this topical review is to assess the scientific evidence and provide expert opinion related to nutritional, psychological and supportive care of women and their infants throughout the prenatal, antenatal and infant periods. METHODS: A consensus expert panel of a paediatrician, gastroenterologists, nurses and dietitians was convened by the European Crohn's and Colitis Organisation. This panel critically reviewed literature related to the non-medical management of patients with IBD during preconception, pregnancy, the postnatal period and the first years of the infant's life. Statements were developed using an e-Delphi process over two rounds and were confirmed when ≥80% of experts agreed with the statements. RESULTS: A total of 19 current practice positions were developed that cover the preconception period, pregnancy and lactation, and early-life exposures associated with risk of IBD. Development of the infant microbiome and its role in the immune system and topics including nutritional optimization, psychological support and education relating to early life were reviewed. CONCLUSIONS: Patients with IBD have unique nutritional and psychosocial needs that may affect fertility and pregnancy outcomes. The early-life environment of infants born to parents with IBD may be associated with subsequent development of IBD in offspring. An MDT is the optimal setting to support and counsel patients throughout the perinatal period.

Pregnancy outcomes in inflammatory bowel disease: Data from a large cohort survey.

OBJECTIVES: Inflammatory bowel disease (IBD) can affect young and reproductively active patients. Our aim was to analyze pregnancy outcomes in a large cohort of women with IBD. METHODS: All women with at least one pregnancy were given a questionnaire regarding the outcome of their pregnancy. They were divided into IBD pregnancies and controls depending on whether pregnancy occurred within or over 10 years prior to the diagnosis of IBD. RESULTS: Three hundred questionnaires were analyzed for a total of 478 pregnancies that led to live-born babies. Age at conception was older in IBD women than in the controls. Active smoking was more frequent in the control group. The risk of intrauterine growth restriction (IUGR) was higher in IBD pregnancies (odds ratio [OR] 3.028, 95% confidence interval [CI] 1.245-7.370, P = 0.013). The week of gestation at delivery was lower in the IBD population. And the risk of cesarean section was higher in IBD pregnancies (OR 1.963, 95% CI 1.274-3.028, P = 0.002). Among women with IBD pregnancy, the risk of preterm birth was higher in patients with active disease at the time of conception (OR 4.088, 95% CI 1.112-15.025, P = 0.030), but lower in patients who continued regular therapy during pregnancy. Similarly, the risk of urgent cesarean section was reduced in the case of disease remission, while the risk of a planned cesarean delivery was higher in patients with perianal disease (OR 11.314, 95% CI 3.550-36.058, P < 0.01). CONCLUSIONS: Our study shows a higher risk of IUGR, cesarean section, and poor blood pressure control in IBD pregnancies. We emphasize the importance of achieving disease remission before considering pregnancy.

Higher volume growth rate is associated with development of worrisome features in patients with branch duct-intraductal papillary mucinous neoplasms.

BACKGROUND: Branch duct-intraductal papillary mucinous neoplasms (BD-IPMNs) are the most common pancreatic cystic tumours and have a low risk of malignant transformation. Current guidelines only evaluate cyst diameter as an important risk factor but it is not always easy to measure, especially when comparing different methods. On the other side, cyst volume is a new parameter with low inter-observer variability and is highly reproducible over time. AIM: To assess both diameter and volume growth rate of BD-IPMNs and evaluate their correlation with the development of malignant characteristics. METHODS: Computed tomography scans and magnetic resonance imaging exams were retrospectively reviewed. The diameter was measured on three planes, while the volume was calculated by segmentation: The volume of the entire cyst was determined by manually drawing a region of interest along the edge of the neoplasm on each consecutive slice covering the whole lesion; therefore, a three-dimensional volume of interest was finally obtained with the calculated value expressed in cm3. Changes in size over time were measured. The development of worrisome features was evaluated. RESULTS: We evaluated exams of 98 patients across a 40.5-mo median follow-up time. Ten patients developed worrisome features. Cysts at baseline were significantly larger in patients who developed worrisome features (diameters P = 0.0035, P = 0.00652, P = 0.00424; volume P = 0.00222). Volume growth rate was significantly higher in patients who developed worrisome features (1.12 cm3/year vs 0 cm3/year, P = 0.0001); diameter growth rate was higher as well, but the difference did not always reach statistical significance. Volume but not diameter growth rate in the first year of follow-up was higher in patients who developed worrisome features (0.46 cm3/year vs 0 cm3/year, P = 0.00634). CONCLUSION: The measurement of baseline volume and its variation over time is a reliable tool for the follow-up of BD-IPMNs. Volume measurement could be a better tool than diameter measurement to predict the development of worrisome features.

Is the age at surgery in Crohn's disease clinically relevant? Differences and peculiarities: a wide single centre experience after long-term follow-up.

PURPOSE: The Montreal classification for Crohn's disease includes "age at diagnosis" as a parameter but few is reported about the age at surgery. The aim of this study is to evaluate the short- and long-term differences in the postoperative surgical outcome and disease behaviour, according to the age at the first surgery. METHODS: Patients consecutively operated for abdominal Crohn's disease during the period 1986-2012 at our centre were systematically analysed according to their age at first surgery. In our retrospective cohort, the age at first surgery ranged from 13 to 83 years, and patients were arbitrarily divided into four groups: ≤ 19 (G1), 20-39 (G2), 40-59 (G3) and ≥ 60 (G4) years old. RESULTS: In total, 1051 patients were included with a median follow-up time of 232 months. The four groups exhibited statistically significant differences in age at diagnosis, smoke habit, time between diagnosis and surgery, disease location and behaviour, history of perianal fistula or abscess, severe malnutrition requiring total parental nutrition before surgery, type of surgery, total length of resected bowel, median duration of hospitalization, incidence of abdominal recurrences and number of surgical recurrences. G1 displays an inverse linear trend with time in the severity of clinical characteristics when compared to G4 groups. On the contrary, the incidence of short-term complications, types of abdominal recurrence and presence of concomitant perianal disease did not vary among groups. In addition, at multivariate analysis, the age at surgery and the disease location were the only independent risk factors for abdominal surgical recurrence. CONCLUSION: Despite first surgery is extremely more frequent between 20 and 59 years, patients from G1 and G4 groups showed clinical differences and peculiarities when compared to the other age groups. The most indolent CD behaviour and occurrence of surgical recurrence was observed in patients having their first abdominal surgery in the elderly, while patients operated before the age of 19 experienced a more aggressive disease course.

Hereditary Colorectal Cancer Syndromes and Inflammatory Bowel Diseases: an ECCO CONFER Multicentre Case Series.

BACKGROUND: Hereditary colorectal cancer syndromes [HCCS] are rare polyposis or nonpolyposis syndromes with a higher risk of developing colorectal cancer [CRC]. Coexisting inflammatory bowel disease [IBD], including ulcerative colitis [UC] and Crohn's disease [CD], with HCCS is exceedingly rare and presumably increases the risk of early-onset CRC. METHODS: This was a multicentre case series performed as a part of the European Crohn's and Colitis Organisation [ECCO] Collaborative Network of Exceptionally Rare case reports [CONFER] project. RESULTS: This report includes 26 patients with IBD (10 UC, 15 CD, and one with IBD unclassified [IBD-U]) and concomitant HCCS. Among these 26 patients([median age 33 years, interquartile range [IQR] 20-44], 15 [57.7%] were males, 24 [92.3%] Caucasians, and two [7.7%] of Arab origin. HCCS was diagnosed before the IBD diagnosis in 11 patients [42.3%], after diagnosis of IBD in 11 patients [42.3%], and concurrently in four patients [15.4%]. Sixteen patients had Lynch syndrome, seven had familial adenomatous polyposis [FAP], two had MYH-associated polyposis [MAP], and one had attenuated FAP [AFAP]. The most frequent genetic mutations were those of APC [n = 7] and MLH1 [n = 7]. Overall, CRC developed in 38.5% of patients [n = 10]: in four patients [40%] after IBD diagnosis, in four [40%] patients before IBD diagnosis, and in two patients the two conditions were diagnosed simultaneously. Eighteen [69.2%] patients underwent colectomy or abdominal surgery: nine patients due to CRC diagnosis, five patients preventively due to the underlying HCCS, three due to the underlying HCCS and concomitant active IBD disease, and one patient because of active IBD disease. One patient died due to CRC. CONCLUSIONS: To date, this is the largest case series of patients with IBD and HCCS. The most frequent diagnosis of HCCS associated with IBD was Lynch syndrome. These data demonstrate the high malignancy rate and surgical intervention rate in this IBD cohort, despite the endoscopic surveillance. The optimal medical approach still needs to be addressed.

Surgery due to Inflammatory Bowel Disease During Pregnancy: Mothers and Offspring Outcomes From an ECCO Confer Multicentre Case Series [Scar Study].

AIMS: i] To evaluate the evolution of pregnancies and offspring after inflammatory bowel disease [IBD] surgery during pregnancy; and ii] to describe the indications, the surgical techniques, and the frequency of caesarean section concomitant with surgery. METHODS: Patients operated on due to IBD during pregnancy after 1998 were included. Participating clinicians were asked to review their databases to identify cases. Data on patients' demographics, IBD characteristics, medical treatments, IBD activity, pregnancy outcomes, surgery, delivery, and foetal and maternal outcomes, were recorded. RESULTS: In all, 44 IBD patients were included, of whom 75% had Crohn's disease; 18% of the surgeries were performed in the first trimester, 55% in the second, and 27% in the third trimester. One patient had complications during surgery, and 27% had postsurgical complications. No patient died. Of deliveries, 70% were carried out by caesarean section. There were 40 newborns alive. There were four miscarriages/stillbirths [one in the first, two in the second, and one in the third trimester]; two occurred during surgery, and another two occurred 2 weeks after surgery; 14% of the surgeries during the second trimester and 64% of those in the third trimester ended up with a simultaneous caesarean section or vaginal delivery. Of the 40 newborns, 61% were premature and 47% had low birth weight; 42% of newborns needed hospitalisation [25% in the intensive care unit]. CONCLUSIONS: IBD surgery during pregnancy remains an extremely serious situation. Therefore, surgical management should be performed in a multidisciplinary team, involving gastroenterologists, colorectal surgeons, obstetricians, and neonatal specialists.

Isoforms of the orphan nuclear receptor COUP­TFII differentially modulate pancreatic cancer progression.

The expression of the nuclear receptor transcription factor (TF) COUP­TFII is broadly associated with cell differentiation and cancer development, including of pancreatic ductal adenocarcinoma (PDAC), a devastating disease with one of the poorest prognoses among cancers worldwide. Recent studies have started to investigate the pathological and physiological roles of a novel COUP­TFII isoform (COUP­TFII_V2) that lacks the DNA­binding domain. As the role of the canonical COUP­TFII in PDAC was previously demonstrated, the present study evaluated whether COUP­TFII_V2 may have a functional role in PDAC. It was demonstrated that COUP­TFII_V2 naturally occurs in PDAC cells and in primary samples, where its expression is consistent with shorter overall survival and peripheral invasion. Of note, COUP­TFII_V2, exhibiting nuclear and cytosolic expression, is linked to epithelial to mesenchymal transition (EMT) and cancer progression, as confirmed by nude mouse experiments. The present results demonstrated that COUP­TFII_V2 distinctively regulates the EMT of PDAC and, similarly to its sibling, it is associated with tumor aggressiveness. The two isoforms have both overlapping and exclusive functions that cooperate with cancer growth and dissemination. By studying how PDAC cells switch from one isoform to the other, novel insight into cancer biology was gained, indicating that this receptor may serve as a novel possible target for PDAC management.

Gastroenteropancreatic Neuroendocrine Neoplasms in Patients with Inflammatory Bowel Disease: An ECCO CONFER Multicentre Case Series.

BACKGROUND: Gastroenteropancreatic neuroendocrine neoplasms [GEP-NENs] have rarely been reported in association with inflammatory bowel diseases [IBDs]. METHODS: An ECCO COllaborative Network For Exceptionally Rare case reports project [ECCO-CONFER] collects cases of GEP-NENs diagnosed in patients with IBD. RESULTS: GEP-NEN was diagnosed in 100 IBD patients; 61% female, 55% Crohn's disease, median age 48 years (interquartile range [IQR] 38-59]). The most common location was the appendix [39%] followed by the colon [22%]. Comprehensive IBD-related data were available for 50 individuals with a median follow-up of 30 months [IQR 11-70] following NEN diagnosis. Median duration of IBD at NEN diagnosis was 84 months [IQR 10-151], and in 18% of cases NEN and IBD were diagnosed concomitantly. At diagnosis, 20/50 were stage-I [T1N0M0], and 28/50 were graded G1 [ki67 ≤2%]. Incidental diagnosis of NEN and concomitantly IBD diagnosis were associated with an earlier NEN stage [p = 0.01 and p = 0.02, respectively]. Exposure to immunomodulatory or biologic therapy was not associated with advanced NEN stage or grade. Primary GEP-NEN were more frequently found in the segment affected by IBD [62% vs 38%]. At the last follow-up data, 47/50 patients were alive, and only two deaths were related to NEN. CONCLUSIONS: In the largest case series to date, prognosis of patients with GEP-NEN and IBD seems favourable. Incidental NEN diagnosis correlates with an earlier NEN stage, and IBD-related therapies are probably independent of NEN stage and grade. The association of GEP-NEN location and the segment affected by IBD may suggest a possible role of inflammation in NEN tumorigenesis.

Primary Hypogammaglobulinaemia with Inflammatory Bowel Disease-Like Features: An ECCO CONFER Multicentre Case Series.

BACKGROUND: Hypogammaglobulinaemia is a disorder characterized by low serum immunoglobulin levels and a high prevalence of gastrointestinal manifestations. In some cases, clinical and endoscopic features are indistinguishable from those of inflammatory bowel disease [IBD]. METHODS: This was a multicentre case series performed as a part of the European Crohn's and Colitis Organisation [ECCO] Collaborative Network of Exceptionally Rare case reports [CONFER] project. RESULTS: This report includes 27 patients with primary hypogammaglobulinaemia and IBD-like features: 20 males and seven females, median age 45.6 years (interquartile range [IQR] 35.2-59). Crohn's disease-like features were noted in 23 patients, and four patients had ulcerative colitis-like features. The diagnosis of hypogammaglobulinaemia preceded a diagnosis of IBD-like features in 20 patients [median of 7 years prior, IQR 2.6-20.6 years], and followed the appearance of IBD-like features in seven cases [median of 1 year after, IQR 0.45-5.6 years]. Hypogammaglobulinaemia aetiologies were common variable immunodeficiency [66.6%], agammaglobulinaemia [7.4%], selective IgA-deficiency [11.1%], Good's syndrome [7.4%], IgG subclass deficiency with IgA deficiency [3.7%] and hyper-IgM [3.7%]. In addition to antibiotics and intravenous immunoglobulin [IVIG] for hypogammaglobulinaemia, 12 patients received IBD-related treatment including 5-aminosalicylate agents [two patients], corticosteroids [one patient], thiopurines [three patients], anti-tumour necrosis factor [four patients] and vedolizumab [two patients]. By the end of the follow-up (44.5 months [IQR 18-81]), 21/27 [77%] patients were in clinical remission. CONCLUSION: This case series describes IBD-like features in patients with hypogammaglobulinaemia. The diagnosis of IBD-like features mainly occurred after that of hypogammaglobulinaemia, with successful recovery in the majority of cases after appropriate treatment.

Relationship between Nutritional Screening Tools and GLIM in Complicated IBD Requiring Surgery.

BACKGROUND: Accurate identification of malnutrition and preoperative nutritional care in Inflammatory Bowel Disease (IBD) surgery is mandatory. There is no validated nutritional screening tool for IBD patients. We developed a novel nutritional screening tool for IBD patients requiring surgery and compared it with other tools. METHODS: we included 62 consecutive patients scheduled for elective surgery. The IBD Nutritional Screening tool (NS-IBD) was developed to screen patients for further comprehensive assessment. NRS-2002, MUST, MST, MIRT, SaskIBD-NR are compared with the new test. All screening tests were subsequently related to new GLIM criteria. RESULTS: according to GLIM criteria, 25 (40%) IBD patients were malnourished (15 CD and 10 UC, 33% vs. 63%, p = 0.036). Stage 1 malnutrition was reported in ten patients, while stage 2 was detected in 15 patients. The comparison of each nutritional risk tool with GLIM criteria showed sensitivity of 0.52, 0.6, 0.6, 0.84, 0.84 and 0.92 for SASKIBD-NR, MUST, MST, NRS-2002, MIRT, and the new NS-IBD, respectively. CONCLUSIONS: in IBD, currently adopted nutritional screening tools are characterized by a low sensitivity when malnutrition diagnosis is performed with recent GLIM criteria. Our proposed tool to detect malnutrition performed the best in detecting patients that may require nutritional assessment and preoperative intervention.

Infliximab is more effective than cyclosporine as a rescue therapy for acute severe ulcerative colitis: a retrospective single-center study.

BACKGROUND: Acute severe ulcerative colitis (ASUC) is a potentially life-threatening disease, and the best option in cases of steroid-refractory disease is still debated. We compared the early- and long-term efficacy and safety of the 2 available "rescue therapies", infliximab (IFX) and cyclosporine (CYS), in this setting. METHODS: We retrospectively evaluated patients admitted for ASUC and treated with "rescue therapy". The primary endpoint was early colectomy-free survival (30 days) and colectomy-free survival until the end of follow up. The secondary endpoints were predictors of colectomy and long-term maintenance of the treatment strategy over time. RESULTS: Of 129 patients admitted, 68 received rescue therapy (47 with IFX), whereas 7 underwent early colectomy (10.3%). At 30 days, fewer patients treated with IFX showed a need for colectomy (8.5% vs. 14.3%) compared to those in the CYS group, though the difference was non-significant (odds ratio [OR] 0.69, 95% confidence interval [CI] 0.10-4.69; P=0.47). No severe side effects due to IFX and CYS were observed. During a mean follow up of 40 months, 23 additional patients (37.7%) underwent colectomy, and the rate was significantly lower in the IFX group (25.6%) than in the CYS group (66.7%) (hazard ratio 0.25, 95%CI 0.10-0.61; P=0.003). Colectomy-free survival was significantly higher in the IFX group than in the CYS group (P=0.018) at 12 months. CONCLUSIONS: In our setting, the early outcomes of IFX and CYS for ASUC were comparable. IFX was associated with significantly lower colectomy rates during the observation period and had a similar safety profile to CYS.
