RESUMO
Inflammatory bowel diseases (IBD) are significantly associated with adverse pregnancy and neonatal outcomes, though the pathomechanism is yet unknown. To investigate the relationship between IBD and adverse pregnancy outcomes by comparing neonatal outcomes and placental histopathology in two matched groups of patients with and without IBD. In this retrospective study, data of all patients who gave birth between 2008-2021 and were diagnosed with IBD were reviewed and compared to a control group matching two control cases for every IBD case. Neonatal outcomes and placental pathology were compared between the groups. Compared to the control group (n=76), the placentas of patients with IBD (n=36) were characterized by significantly lower placental weight (p < 0.001), and higher rates of maternal vascular malperfusion lesions (MVM, p < 0.001) and maternal and fetal inflammatory response lesions (p < 0.001). Neonates of patients with IBD were more frequently small for gestational age (SGA) (p=0.01), with increased rates of need for phototherapy (p = 0.03), respiratory morbidity and NICU admission (p < 0.001 for both outcomes). Multivariate logistic regression analyses adjusting for possible confounders (including maternal age, gestational age, chronic hypertension, smoking, and thrombophilia) confirmed the independent association between IBD and composite MVM lesions (aOR 4.31, p < 0.001), maternal inflammatory responses (aOR 40.22, p < 0.001) and SGA infants (aOR 4.31, p = 0.013). IBD is associated with increased rates of placental histopathological lesions and adverse pregnancy outcomes, including SGA infants. These novel findings imply the role of placental malperfusion and inflammatory processes in pregnancy complications of IBD patients, which should be followed accordingly. Approval of local ethics committee # WOMC-0219-20.
RESUMO
BACKGROUND: Identification of pancreatic cancer (PC) local invasion is crucial to optimize patients' selection for surgery. AIMS: To determine the diagnostic accuracy of contrast-enhanced computed tomography (CECT) and endoscopic ultrasound (EUS) in local staging of PC. METHODS: We performed a multicenter study including all patients with PC who underwent surgery. RESULTS: One hundred twelve patients were included. Surgical findings of peri-pancreatic lymph nodes (LN), vascular and adjacent organ involvement were seen in 67 (59.8%), 33 (29.5%) and 19 patients (17%), respectively. The diagnostic performance of EUS was better than CECT in peri-pancreatic LN. The sensitivity, specificity, positive predictive value (PPV) and negative predictive (NPV) of CECT vs. EUS were 28.4%, 80%, 67.9% and 42.9% vs. 70.2%, 75.6%, 81% and 63%, respectively. For vascular and adjacent organ involvement, the sensitivity, specificity, PPV and NPV were 45.5%, 93.7%, 75%, 80.4% and 31.6%, 89.2%, 37.5% and 86.5% for CECT, respectively, vs. 63.6%, 93.7%, 80.8%, 86.1% and 36.8%, 94.6%, 58.3% and 88% for EUS, respectively. Combining both CECT and EUS, the sensitivity for peri-pancreatic LN, vascular and adjacent organ involvement improved (76.1%, 78.8% and 42%), respectively. CONCLUSION: EUS was superior to CECT in local staging. Combined EUS and CECT had a higher sensitivity than either alone.

BACKGROUND: Crohn's disease (CD) and ulcerative colitis (UC) are chronic, immune-mediated inflammatory bowel diseases (IBD) affecting millions of people worldwide. IBD therapies, designed for continuous immune suppression, often render patients more susceptible to infections. The effect of the immune suppression on the risk of coronavirus disease-19 (COVID-19) is not fully determined yet. OBJECTIVE: To describe COVID-19 characteristics and outcomes and to evaluate the association between IBD phenotypes, infection outcomes and immunomodulatory therapies. METHODS: In this multi-center study, we prospectively followed IBD patients with proven COVID-19. De-identified data from medical charts were collected including age, gender, IBD type, IBD clinical activity, IBD treatments, comorbidities, symptoms and outcomes of COVID-19. A multivariable regression model was used to examine the effect of immunosuppressant drugs on the risk of infection by COVID-19 and the outcomes. RESULTS: Of 144 IBD patients, 104 (72%) were CD and 40 (28%) were UC. Mean age was 32.2 ± 12.6 years. No mortalities were reported. In total, 94 patients (65.3%) received biologic therapy. Of them, 51 (54%) at escalated doses, 10 (11%) in combination with immunomodulators and 9 (10%) with concomitant corticosteroids. Disease location, behavior and activity did not correlate with the severity of COVID-19. Biologics as monotherapy or with immunomodulators or corticosteroids were not associated with more severe infection. On the contrary, patients receiving biologics had significantly milder infection course (p = 0.001) and were less likely to be hospitalized (p = 0.001). Treatment was postponed in 34.7% of patients until recovery from COVID-19, without consequent exacerbation. CONCLUSION: We did not witness aggravated COVID-19 outcomes in patients with IBD. Patients treated with biologics had a favorable outcome.
RESUMO
BACKGROUND: We sought to define the effectiveness and safety of tofacitinib in a real-world (RW) cohort of Israeli patients with moderate to severe ulcerative colitis (UC). METHODS: This was a multi-center retrospective observational cohort study (2019-2020) to assess the effectiveness and safety of tofacitinib induction and maintenance therapy up to 26 weeks. Clinical response and remission were defined as a reduction in Simple Clinical Colitis Activity Index (SCCAI) or partial Mayo score (PMS) of ≥3 points, and SCCAI ≤2 or a PMS ≤1, respectively. RESULTS: We included 73 patients, 47% male; median age 26 years [IQR: 19.5-39.5], disease duration 7 years [IQR: 2.5-14.5], follow-up 7.1 months [IQR: 3-12], 91% biologics-experienced, and 74% ≥ 2-biologics. Half of patients used concomitant corticosteroids (CS). Overall, 56.1% discontinued therapy due to either lack of response and/or adverse events (AEs), median time to discontinuation - 9.7 months [IQR 3.4-16]. Overall, response, remission, and CS-free-remission were achieved in 47.6%, 20.6%, and 17.5% of patients, respectively. At early maintenance (week 26), response, remission, and CS-free-remission were achieved in 65%, 22.5%, and 20% of patients, respectively. At week 26, tofacitinib 10 mg BID was still used in 43%. Seventeen patients (23.2%) had an adverse event including herpes zoster- 2.7%, hospitalization- 12.3%, and colectomy- 2.7%. CONCLUSIONS: Tofacitinib was effective in achieving CS-free-remission in about 1/5 of highly biologics -experienced patients with UC. Despite a considerable proportion of patients maintained on tofacitinib 10 mg bid, it was well tolerated and safe. Earlier positioning of tofacitinib in the therapeutic algorithm may result in improved outcomes.

BACKGROUND: It is still of debate whether the advent of biologics has been associated with a change in the natural history of ulcerative colitis [UC]. In this nationwide study we evaluated trends of long-term outcomes in all patients diagnosed with UC in Israel during the biologic era. METHODS: Data in the epi-IIRN cohort were retrieved from the four Israeli Health Maintenance Organizations covering 98% of the population, and linked to the Ministry of Health prospective registry on surgeries and hospitalizations. Joinpoint Regression and Kaplan-Meier survival analyses were used, reporting annual average percentage change [AAPC] for each outcome. RESULTS: A total of 13 231 patients were diagnosed with UC since 2005 (1426 [11%] paediatric-onset, 10 310 [78%] adults, 1495 [11%] elderly) with 93 675 person-years of follow-up. The probabilities of surgery after 1, 3 and 5 years from diagnosis were 1.1, 2.3 and 4.1%, respectively, and the corresponding rates of hospitalizations were 22, 33 and 41%. The overall utilization of biologics in UC increased from 0.1% in 2005 to 9.6% in 2019 [AAPC 22.1%] and they were prescribed earlier during the disease course (median of 5.6 years [interquartile range 2.8-9.1] in 2005-2008 vs 0.8 years [0.4-1.5] in 2015-2018; p < 0.001]. Annual rates of surgeries [AAPC -1.3; p = 0.6] and steroid-dependency [AAPC -1.2; p = 0.3] remained unchanged, while rates of hospitalizations slightly decreased [AAPC -1.2; p < 0.001]. Outcomes were consistently worse in paediatric-onset disease than in adults, despite higher utilization of biologics [28% vs 12%, respectively; p < 0.001]. CONCLUSION: During the biologic era rates of surgeries and steroid-dependency have remained unchanged in patients with UC, while rates of hospitalizations have slightly decreased.

BACKGROUND: The effectiveness of biologics for improving long-term outcomes in patients with Crohn's disease [CD] is still controversial. In this nationwide study, we aimed to evaluate trends of long-term outcomes in all CD patients in Israel during the biologics era. METHODS: Trends of outcomes were analysed using data from the four Israeli health maintenance organisations, covering 98% of the population; joinpoint regression models were used to explore changes of these trends over 2005 to 2019. RESULTS: A total of 16 936 patients were diagnosed with CD in Israel since 2005 (2932 [17%] paediatric onset, 14 004 [83%] adult onset) with 114 947 person-years of follow-up. The cumulative rate of any CD related surgery was 5%, 9%, 11%, and 14% at 1, 3, 5, and 10 years from diagnosis. The increase in use of biologics was sharp (from 8.9% to 36%; average annual percent change [AAPC], 14.3%), and the time to biologics was shorter in recent years (median time of 4.8 [1.9-8.1] years in those diagnosed in 2005-2008 compared with 0.5 [0.2-1.1] years in those diagnosed in 2015-2018; pâ <â 0.001). A significant decrease was noted in the hazard of hospitalisations (1.3 [0.1-4.6] years compared with 0.2 [0.02-0.9] years; pâ <â 0.001), steroid dependency (1.5 [0.2-5.4] years compared with 0.1 [0.02-0.4] years; pâ <â 0.001), and intestinal surgeries [4.7 [1.6-8.2] years compared with 0.6 [0.2-1.4] years; pâ <â 0.001), but not of perianal surgery (4.2 [1.1-7.7] years compared with 0.6 [0.2-1.4] years; pâ =â 0.2). Outcomes were consistently worse in paediatric onset compared with adults. CONCLUSIONS: The rates of hospitalisations, steroid dependency, and intestinal resections decreased in association with increased use of biologics both in children and in adults, but not the rate of perianal surgeries.

BACKGROUND: Family studies support a genetic predisposition to inflammatory bowel diseases (IBD), but known genetic variants only partially explain the disease heritability. Families with multiple affected individuals potentially harbour rare and high-impact causal variants. Long regions of homozygosity due to recent inbreeding may increase the risk of individuals bearing homozygous loss-of-function variants. This study aimed to identify rare and homozygous genetic variants contributing to IBD. METHODS: Four families with known consanguinity and multiple cases of IBD were recruited. In a family-specific analysis, we utilised homozygosity mapping complemented by whole-exome sequencing. RESULTS: We detected a single region of homozygosity shared by Crohn's disease cases from a family of Druze ancestry, spanning 2.6 Mb containing the NOD2 gene. Whole-exome sequencing did not identify any potentially damaging variants within the region, suggesting that non-coding variation may be involved. In addition, affected individuals in the families harboured several rare and potentially damaging homozygous variants in genes with a role in autophagy and innate immunity including LRRK1, WHAMM, DENND3, and C5. CONCLUSION: This study examined the potential contribution of rare, high-impact homozygous variants in consanguineous families with IBD. While the analysis was not designed to achieve statistical significance, our findings highlight genes or loci that warrant further research. Non-coding variants affecting NOD2 may be of importance in Druze patients with Crohn's disease.
RESUMO
INTRODUCTION: Perianal Crohn's disease is correlated with a significant decrease in quality of life and can predict unfavorable outcomes. In this condition, it is recommended that a multidisciplinary team including a gastroenterologist, colorectal surgeon and radiologist will be involved to optimize therapeutic decisions. Despite the advent of biologic and surgical therapies, the success rate of therapy is unsatisfactory and may result in a high chance of recurrence. In recent years, novel therapies have been introduced which include local injection of mesenchymal stem cells and surgical techniques which can improve the outcome and quality of life of the patients. The goal of this review, is to raise the awareness and summarize the therapeutic options available for the treatment of perianal Crohn's disease.

BACKGROUND: The IBD disability index (IBDDI) has been shown to be valid and reliable. We compared the distributional and predictive properties of the IBDDI, when collected from five populations of people living with IBD- from Winnipeg, Chicago, Toronto, Hong Kong, and Jerusalem. METHODS: People with IBD from five jurisdictions were invited to complete a survey including the IBDDI, the World Health Organization Disability Assessment Scale, the Work and Social Adjustment Scale, the IBDQ, the Kessler-6 distress scale, and the Stanford presenteeism scale. Between sites, we compared the correlation between IBDDI and the other 4 measures of disability/quality of life/distress, and the association between IBDDI and presenteeism and having been hospitalized in the past year. RESULTS: There were 1121 participants from Winnipeg, 511 from Chicago, 147 from Toronto, 97 from Hong Kong, and 96 from Jerusalem. The majority had Crohn's disease. Although the mean IBDDI score varied by site, the correlation between IBDDI and each of the other 4 measures of disability/QOL/distress was nearly identical. Similarly, the regression coefficient showing the association between IBDDI and presenteeism was nearly identical in all sites, and the risk ratios showing the association between hospitalization and high IBDDI was similar in all sites. CONCLUSION: The correlation between IBDDI and different measures of disability/QOL/distress was similar across all sites. There is strong evidence of the association between IBD-related disability and presenteeism, and between hospitalization and high IBD-related disability, and that the associations are the same across different populations. The severity of disability that an individual with a given IBDDI score has is directly comparable across populations.

INTRODUCTION: nflammatory bowel diseases (IBD) which include Crohn's disease and ulcerative colitis cause chronic remitting inflammation of the gastrointestinal tract with the potential of bowel wall injury which can lead to disability. AIMS: This study aimed to evaluate the degree of disability among IBD patients in Israel using validated scales and to identify factors that are associated with disability. Furthermore, the study aimed to examine the association between disability and quality of life (QoL) among patients. METHODS: The study population included 96 patients who attended a dedicated IBD clinic, (71 patients (pts) with Crohn's disease (CD), 22 pts with ulcerative colitis (UC) and 3 pts with IBD-undefined (IBD-U)). The participants completed a 5-part questionnaire which included demographic parameters, a validated QoL measure (inflammatory bowel disease questionnaire (IBDQ), two validated disability scales (the work and social adjustment scale (WSAS) and the World Health Organization Disability Assessment Schedule V.2.0 (WHODAS2.0), employment status, and a disease activity measure (the Manitoba IBD index (MIBDI). RESULTS: Major disability was found among 20% of the participants (as defined by a WSAS score ≥17). Major disability was significantly associated with lower QoL (p<0.001) and with recognition of disability from the National Insurance Institute of Israel ("Hamosad Lebituach Leumi") (p=0.005). Significant association was found between WHODAS2.0 and low QoL (r=-0.763,p<0.001). There were no significant differences in rates of major disability among patients with CD vs. those with UC. CONCLUSIONS: Approximately one fifth of IBD patients in Israel have major disability, which in turn, is associated with a decreased quality of life and recognition of disability from the National Insurance Institute of Israel. There were no significant differences in rates of disability between patients with CD vs. those with UC.

Fusobacterium nucleatum is a common oral bacterium that is enriched in colorectal adenomas and adenocarcinomas (CRC). In humans, high fusobacterial CRC abundance is associated with chemoresistance and poor prognosis. In animal models, fusobacteria accelerate CRC progression. Targeting F. nucleatum may reduce fusobacteria cancer progression and therefore determining the origin of CRC F. nucleatum and the route by which it reaches colon tumors is of biologic and therapeutic importance. Arbitrarily primed PCR performed previously on matched same-patients CRC and saliva F. nucleatum isolates, suggested that CRC F. nucleatum may originate from the oral cavity. However, the origin of CRC fusobacteria as well as the route of their arrival to the tumor have not been well-established. Herein, we performed and analyzed whole genome sequencing of paired, same-patient oral, and CRC F. nucleatum isolates and confirmed that CRC-fusobacteria originate from the oral microbial reservoir. Oral fusobacteria may translocate to CRC by descending via the digestive tract or using the hematogenous route during frequent transient bacteremia caused by chewing, daily hygiene activities, or dental procedures. Using the orthotropic CT26 mouse model we previously showed that IV injected F. nucleatum colonize CRC. Here, we compared CRC colonization by gavage vs. intravenous inoculated F. nucleatum in the MC38 and CT26 mouse orthotropic CRC models. Under the tested conditions, hematogenous fusobacteria were more successful in CRC colonization than gavaged ones. Our results therefore provide evidence that the hematogenous route may be the preferred way by which oral fusobacteria reach colon tumors.

INTRODUCTION: Ustekinumab is an effective treatment of Crohn's disease (CD). Real-world data addressing the efficacy and safety of ustekinumab are scarce. AIM: Our aim was to assess the safety and efficacy of ustekinumab in a large national patient cohort. METHODS: A prospective multicenter study, in which we followed patients with active CD treated with ustekinumab for 24 weeks. Induction dose was intravenous ranging from 260 to 520 mg, according to body weight, followed by 90 mg doses given subcutaneously every 8 weeks. Clinical response was defined as a reduction of at least 1 severity category, as defined by Harvey-Bradshaw index (HBI). Patients with HBI < 5 were considered to be in clinical remission. Patients who stopped needing steroids at week 24 were defined as being in steroid-free clinical remission. RESULTS: A total of 106 CD patients from eight Israeli centers were included. All patients were previously exposed to at least one biological agent. Our cohort consisted of 65 (61.3%) females. Mean age was 41 ± 14 years with an average disease duration of 12.2 ± 8 years. A total of 96 (90.5%) patients continued treatment throughout week 24. Clinical response was observed in 52% of these patients with mean HBI reduction from 8.34 ± 3.8 to 6.8 ± 4.4 at week 24 (p = 0.001). Clinical remission was achieved in 33 patients (31.1%). Moreover, the number of patients requiring steroid treatment was reduced by 66% at week 24. Out of 106 patients, 11 patients (10.4%) discontinued treatment: 3 due to adverse events (2.8%), 7 due to a lack of response, and 1 who was lost to follow-up. Following 24 weeks of treatment, 15 patients reported minor adverse events. CONCLUSIONS: In a large real-world Israeli cohort of non-naïve-to-biological-treatment CD patients, ustekinumab was effective and safe in induction of clinical remission with a significant reduction in the number of patients requiring steroid treatment.

BACKGROUND: Few studies describe the radiological and laboratory characteristics of patients with Crohn's disease (CD) with intra-abdominal fistulae. OBJECTIVES: We aimed to describe a cohort of CD patients with intra-abdominal fistulae and determine characteristics associated with complex fistulae. METHODS: Data were gathered from medical records and imaging studies of patients. Evaluation included type of fistula, number of fistulae, and radiological characteristics. RESULTS: A total of 205 fistulae in 132 patients were identified with an average patient age of 31 (±12) years. The average time from CD diagnosis to fistula development was 7 years. The most common type of fistula was entero-enteric (53%). Patients with an extra-intestinal fistula presented with an average of 1.96 fistulae, compared with an average of 1.28 fistulae for those with a fistula limited to the bowel (p =0.01). Except for the number of fistula no other significant differences were observed in radiological characteristics of patients who were diagnosed with a fistula at time of CD diagnosis compared to those diagnosed with a fistula later. CONCLUSIONS: The most common CD-associated intra-abdominal fistulae are entero-enteric and entero-colonic fistulae. An extra-intestinal fistula and diagnosis of a fistula subsequent to diagnosis of CD were associated with an increased number of fistulae per patient.

BACKGROUND: Inflammatory bowel diseases (IBD) is a heterogenous, lifelong disease, with an unpredictable and potentially progressive course, that may impose negative psychosocial impact on patients. While informed patients with chronic illness have improved adherence and outcomes, previous research showed that the majority of IBD patients receive insufficient information regarding their disease. The large heterogeneity of IBD and the wide range of information topics makes a one-size fits all knowledge resource overwhelming and cumbersome. We hypothesized that different patient profiles may have different and specific information needs, the identification of which will allow building personalized computer-based information resources in the future. AIM: To evaluate the scope of disease-related knowledge among IBD patients and determine whether different patient profiles drive unique information needs. METHODS: We conducted a nationwide survey addressing hospital-based IBD clinics. A Total of 571 patients completed a 28-item questionnaire, rating the amount of information received at time of diagnosis and the importance of information, as perceived by participants, for a newly diagnosed patient, and for the participants themselves, at current time. We performed an exploratory factor analysis of the crude responses aiming to create a number of representative knowledge domains (factors), and analyzed the responses of a set of 15 real-life patient profiles generated by the study team. RESULTS: Participants gave low ratings for the amount of information received at disease onset (averaging 0.9/5) and high ratings for importance, both for the newly diagnosed patients (mean 4.2/5) and for the participants themselves at current time (mean 3.5/5). Factor analysis grouped responses into six information-domains. The responses of selected profiles, compared with the rest of the participants, yielded significant associations (defined as a difference in rating of > 0.5 points with a P < 0.05). Patients with active disease showed a higher interest in work-disability, stress-coping, and therapy-complications. Patients newly diagnosed at age > 50, and patients with long-standing disease (> 10 years) showed less interest in work-disability. Patients in remission with mesalamine or no therapy showed less interest in all domains except for nutrition and long-term complications. CONCLUSION: We demonstrate unmet patient information needs. Analysis of various patient profiles revealed associations with specific information topics, paving the way for building patient-tailored information resources.

BACKGROUND AND AIMS: To date, there are no validated measures in IBD to assess the level of preparedness for transition into adult health care. The purpose of this study was to develop and assess the reliability and validity of a "Transition Readiness" (TR) measure for adolescents with IBD, as well as to evaluate the level of TR synchronicity between adolescents themselves, their parents, and their pediatric gastroenterologists. METHODS: A self-assessment tool was created to evaluate TR. Items were reviewed for face validation by IBD experts, and an exploratory factor analysis was performed which yielded 3 distinct domains. The study cohort included adolescents aged 12-21 yrs, their parents, and their physicians in pediatric IBD centers. Correlations between patient/parent/physician TR between each of the domains and the overall TR score to age were assessed. RESULTS: 63 subjects (average age 16.6 yrs/79% Crohn's disease/44% male) participated in this study. There was a significant correlation between the scoring of adolescents and parents on all three domains. The correlation between adolescents and physicians, as well as between parents and physicians, was only consistent for self-efficacy. Self-efficacy significantly correlated with age, while the correlations between perceived knowledge and perception of medical care with age were not significant. CONCLUSION: Validation of a novel TR measurement for adolescents with IBD demonstrated a good correlation between patients and parents. Out of the three proposed constructs, perceived self-efficacy is the most salient measure.
RESUMO
The injection of placental stromal cells isolated from fetal human tissues (f-hPSC) was reported to indirectly induce tissue regeneration in different animal models. A procedure of f-hPSC isolation from fragments of both selected fresh or cryopreserved bulk placental neonate tissues is proposed, based on their high migratory potential,. The fragments of the desired fetal placental tissues are adhered to a culture dish by traces of diluted fibrin and covered with culture medium. Spontaneous migration of pure f-hPSC from the tissue fragments to the cell culture dishes is followed by their rapid expansion by numerous passages. The isolated f-hPSC express typical mesenchymal surface antigens, including CD29, CD105, CD166 and CD146, with negative expression of white blood cell lineage and endothelial cells markers. Optimal yields of f-hPSC cultures can also be obtained from tissue samples cryopreserved in medium composed of 10% dimethyl sulfoxide (M2SO) and 50% fetal calf serum. Slightly better yields are obtained with media supplemented with 1% human albumin. Medium with 5% M2SO and/or 0.25â¯mg/ml PEG yielded inferior results. The f-hPSC from fresh or cryopreserved tissues express similar cell markers and growth kinetics. The proposed isolation protocol may also be applied for high yield isolation of stromal cells from fresh and cryopreserved tissue of other organs.
