Abstract Background and Aims The prognosis of lymphoma that occurs in patients with inflammatory bowel disease [IBD] is poorly known. Methods A multicentre retrospective cohort analysis was done in seven French tertiary centres from 1999 to 2019. Only lymphoma occurring in patients with previous established diagnosis of IBD were analysed. The primary outcome was progression-free survival at 3 years. Results A total of 52 patients [male 65%, Crohn’s disease 79%, median age 48.3 years, median duration of IBD 10.1 years] were included, of whom 37 had been previously exposed to immunosuppressants and/or biologics for at least 3 months and 20 had primary intestinal lymphomas. The lymphoma histological types were: diffuse large B cell lymphomas [N = 17], Hodgkin lymphomas [N = 17], indolent B cell lymphomas [N = 12], and others including T cell lymphomas, mantle cell lymphomas, and unclassifiable B cell lymphoma [N = 6]. The median follow-up after lymphoma was 5.1 years (interquartile range [IQR] 4–7.8). Progression-free survival at 3 years was 85% in the overall population (95% confidence interval [CI] 75%–96%) with no significant difference between the exposed and unexposed group, 79% for patients exposed to immunosuppressants and/or biologics [95% CI 67%–94%], and 83% for patients diagnosed with primary intestinal lymphoma [95% CI 67%–100%]. No relapse of IBD has been observed during chemotherapy. The IBD relapse rate at the end of the last chemotherapy cycle was 23% at 3 years [95% CI 11%-39%] in the overall population. Conclusions In this large cohort, the prognosis for lymphomas occurring in IBD appears to be good and similar to what is expected, irrespective of the exposure to biologics and/or immunosuppressants.

T follicular helper (Tfh) cells represent a novel subset of CD4+ T cells which can provide critical help for germinal center (GC) formation and antibody production. The Tfh cells are characterized by the expression of CXC chemokine receptor 5 (CXCR5), programmed death 1 (PD-1), inducible costimulatory molecule (ICOS), B cell lymphoma 6 (BCL-6), and the secretion of interleukin-21 (IL-21). Given the important role of Tfh cells in B cell activation and high-affinity antibody production, Tfh cells are involved in the pathogenesis of many human diseases. Inflammatory bowel disease (IBD) is a group of chronic inflammatory diseases characterized by symptoms such as diarrhea, abdominal pain, and weight loss. Ulcerative colitis (UC) and Crohn’s disease (CD) are the most studied types of IBD. Dysregulated mucosal immune response plays an important role in the pathogenesis of IBD. In recent years, many studies have identified the critical role of Tfh cells and IL-21 in the pathogenic process IBD. In this paper, we will discuss the role of Tfh cells and IL-21 in IBD pathogenesis.

Abstract Background: Primary mediastinal B-cell lymphoma (PMBCL) is a subtype of diffuse large B-cell lymphoma originating from the thymus with its own epidemiological, clinical, immunophenotypic and prognostic features and that was included as a distinct clinical entity in the last World Health Organization classification (2008). It is more prevalent in young female, and is characterized by a large mediastinal mass, with frequent infiltration of adjacent structures. Dissemination by distant sites may be identified at diagnosis or during the disease progression. It shows many similar aspects to nodular sclerosis Hodgkin’s Lymphoma in terms of clinical, pathological and immunohistochemical features. The standard treatment is based on multidrug regimens containing anthracyclines associated with rituximab and consolidation with radiotherapy. A recent study published in the NEJM in 2013, with a single-arm treatment with infusional dose-adjusted DA-EPOCH-R with no radiotherapy in untreated PMBCL, demonstrated 97% of overall survival (OS) and 93% of event-free survival (EFS) with a median of 5 years of follow-up. Methods: We analyzed retrospectively 40 patients with PMBCL treated at São Paulo’s Cancer Institute from June 2007 to January 2014. The objectives of the study were to compare the complete response (CR), progression-free survival (PFS) and overall survival (OS) rates between two different treatment strategies. All patients were initially evaluated with blood tests, whole-body computed tomography (CT) or fluorodeoxyglucose-positron-emission tomography (PET-CT) and bone marrow biopsy. Two chemotherapy regimens were used in the patient’s treatment: 6 to 8 cycles of conventional R-CHOP 21 with or without radiation therapy (n = 23) and R-CHOP regimen with addition etoposide (DA-EPOCH-R or R-CHOEP) with or without radiotherapy (n = 17). After 4 cycles of treatment, patients were evaluated for response to determine the total number of cycles (6 or 8). Results Among the 40 enrolled patients, 65% were female with median age of 31 years (range 14 to 62 years). The median size of the mediastinal mass was 13cm in the longest axis. Half of the patients (50%) were in advanced stage (III or IV of Ann Arbor staging) and 75% were in good prognosis category of R-IPI ( 1 or 2 risk factors of the International Prognostic Index Score for non Hodgkin lymphoma). 57,5% of patients were treated with R-CHOP and 42,5% had etoposide as part of the their treatment regimen (12,5% DA-EPOCH-R and 30% R-CHOP plus etoposide (100mg/m2 D1-D3). There was no statistically significant difference in CR rate between RCHOP vs RCHOP + etoposide (86.9% vs 86.6%). There were no differences in PFS or OS for the 2 groups (p=0.8202 and 0.9410). Conclusion The addition of etoposide to RCHOP regimen appears to increase OS and PFS of patients with untreated PMBCL as previously demonstrated. In our service, where there is difficult in hospitalization for the administration of infusional regimens such as DA-EPOCH-R, it was necessary to adjust for outpatient to R-CHOEP. The comparison between the two groups (RCHOP vs RCHOEP/DA-EPOCH-R) showed no statistically significant difference in CR, OS and PFS. However, the median of follow-up of patients who received etoposide was not sufficient to analyze the data adequately. Overall Survival Figure 1.

Abstract Background Colorectal strictures have been considered independent risk factors for neoplasia in patients with inflammatory bowel disease (IBD). We examined the association between colorectal stricture and subsequent risk of colorectal neoplasia (CRN) in patients with IBD colitis undergoing colonoscopic surveillance. Methods We conducted a retrospective cohort analysis of patients with IBD colitis enrolled in colonoscopic surveillance for CRN at an academic medical center between 2005 and 2017. Inclusion criteria were IBD involving the colon for ≥8 years (or any duration with primary sclerosing cholangitis [PSC]) undergoing surveillance. Exclusion criteria were advanced CRN (ACRN; colorectal cancer [CRC] or high-grade dysplasia [HGD]) prior to or at enrollment, prior colectomy, or limited (<30%) disease extent or proctitis. Multivariable logistic and Cox regression analysis estimated the association between colorectal stricture on the index colonoscopy and ACRN, CRN (indefinite dysplasia, low-grade dysplasia, HGD, CRC), or colectomy. Results Among 789 patients with IBD undergoing CRC surveillance, 72 (9%; 70 with Crohn’s colitis) had a colorectal stricture on index colonoscopy. There was no significant difference in the frequency of ACRN or requirement for colectomy between patients with vs without a colorectal stricture (P > .05). Colorectal stricture was not associated with subsequent ACRN (adjusted odds ratio [aOR], 1.41; 95% CI, 0.49–4.07), CRN (aOR, 1.15; 95% CI, 0.51–2.58), or colectomy (aOR, 1.10; 95% CI, 0.65–1.84). Conclusions In this analysis of patients with IBD colitis undergoing CRN surveillance, the presence of a colorectal stricture was not independently associated with risk of ACRN or colectomy. Multicenter, prospective studies are needed to confirm these findings, particularly in patients with ulcerative colitis–associated colorectal stricture.

Long Term Prognosis

Abstract Background: Many clinical trials have documented the efficacy of rituximab in B-cell lymphomas. However, it remains unclear whether rituximab will improve long-term prognosis of the patients. This multicenter retrospective cohort study was conducted to evaluate the clinical impact of the drug in the treatment of B-cell lymphomas. Study design: We retrospectively analyzed clinical characteristics, 2-year progression-free survival(2y PFS) and 2-year overall survival(2y OS) of all B-cell lymphoma patients who were newly diagnosed and initially treated with either CHOP-like regimen alone (R(−) group) or in combination with rituximab (R(+) group) between 2000 and 2004 at our 20 hospitals belonging to the National Hospital Organization. Since rituximab was approved in 2002 for indolent B-cell lymphomas and in 2003 for aggressive B-cell lymphomas in Japan, the patients were almost automatically divided into the 2 groups dependent on the year they underwent treatment. Results: Of the 1,072 patients enrolled, 335 were given rituximab, while 737 did not receive it for the initial induction therapy. 2y PFS was 74.3% and 61.2% for R(+) group and R(−) group, respectively(P<.0001). 2y OS also significantly improved with the addition of rituximab, 86.6% vs 65.3%(P<.0001). In 746 patients with diffuse large B-cell lymphoma, R(+) group (183 patients) and R(−) group (563 patients) showed 2y PFS of 71.6% and 62.2% (P=.0017), 2y OS of 78.5% and 62.5% (P<.0001) respectively. In 195 patients with follicular lymphoma, R(+) group (104 patients) and R(−) group (91 patients) exhibited 2y PFS of 80.1% and 64.5% (P<.0001), 2y OS of 94.9% and 81.5% (P<.0001), respectively. Conclusion: The addition of rituximab to the chemotherapy regimen significantly improves the clinical outcome in patients with previously untreated B-cell lymphoma regardless of the clinical aggressiveness.

Background:Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is considered as a risk factor of low bone mineral density (BMD). In fact, the prevalence of osteoporosis ranges from 17% to 41% in IBD patients. The possible contributing factors may include malabsorption, glucocorticoid treatment and coexisting comorbiditiesObjectives:The purpose of our work was to determine the frequency and the determinants of osteoporosis in patients with IBD and to assess whether there is a difference in BMD status between UC and CD.Methods:This is a retrospective study, over a period of 5 years (from January 2014 to December 2018) and including patients followed for IBD who had a measurement of BMD by DEXA. Clinical, anthropometric and densitometric data (BMD at the femoral and vertebral site) were recorded. The WHO criteria for the definition of osteoporosis and osteopenia were applied.Results:One hundred and five patients were collected; among them 45 were men and 60 were women. The average age was 45.89 years old. The average body mass index (BMI) was 25.81 kg/m2 [16.44-44.15]. CD and UC were diagnosed in respectively 57.1% and 42.9%. A personal history of fragility fracture was noted in 4.8%. Hypothyroidism was associated in one case. Early menopause was recorded in 7.6%. 46.8% patients were treated with corticosteroids. The mean BMD at the vertebral site was 1.023 g/cm3 [0.569-1.489 g/cm3]. Mean BMD at the femoral site was 0.920g/cm3 [0.553-1.286g / cm3]. The mean T-score at the femoral site and the vertebral site were -1.04 SD and -1.27 SD, respectively. Osteoporosis was found in 25.7% and osteopenia in 37.1%. Osteoporosis among CD and UC patients was found in respectively 63% and 37%. The age of the osteoporotic patients was significantly higher compared to those who were not osteoporotic (52.23 vs 43.67 years, p = 0.01). We found a significantly higher percentage of osteoporosis among men compared to women (35.6% vs 18.3%, p=0.046). The BMI was significantly lower in the osteoporotic patients (23.87 vs 26.48 kg/m2, p=0.035) and we found a significant correlation between BMI and BMD at the femoral site (p=0.01). No increase in the frequency of osteoporosis was noted in patients treated with corticosteroids (27.9% vs 21.6%, p=0.479). Comparing the UC and CD patients, no difference was found in baseline characteristics, use of steroids or history of fracture. No statistically significant difference was found between UC and CD patients for osteoporosis(p=0.478), BMD at the femoral site (p=0.529) and at the vertebral site (p=0.568).Conclusion:Osteoporosis was found in 25.7% of IBD patients without any difference between CD and UC. This decline does not seem to be related to the treatment with corticosteroids but rather to the disease itself. Hence the interest of an early screening of this silent disease.Disclosure of Interests:None declared

Abstract Background Appropriate management of inflammatory bowel disease (IBD) often requires multiple specialist appointments per year. Living in rural locations may pose a barrier to regular specialist care. Saskatchewan (SK) has a large rural population. Prior to COVID-19, telehealth (TH) in SK was not routinely used for either patient assessment or follow up. Furthermore, TH was exclusively between hospitals and specific TH sites without direct contact using patient’s personal phones. Aims The objective of this study was to assess the differences in demographics, disease characteristics, outcomes, and health care utilization between patients from rural SK with IBD who used TH and those who did not. Methods A retrospective chart review was completed on all rural patients (postal code S0*) with IBD in SK who were followed at the Multidisciplinary IBD Clinic in Saskatoon between January 2018 and February 2020. Patients were classified as using TH if they had ever used it. Information on demographics, disease characteristics, and access to IBD-related health care in the year prior to their last IBD clinic visit or endoscopy was collected. Data was not collected for clinic visits after March 1, 2020 as all outpatient care became remote secondary to the COVID-19 pandemic. Mean, standard deviations, median and interquartile ranges (IQR) were reported. Mann-Witney U and Chi-Square tests were used to determine differences between the groups. Results In total, 288 rural SK IBD patients were included, 30 (10.4%) used TH and 258 (89.6%) did not. Patient demographics were not significantly different between the two groups; although, there was a statistically significant difference in the proportion of ulcerative colitis patients (17% TH vs. 38% non-TH, p=0.02). The percentage of patients with clinical remission was 87% for TH patients and 74% for non-TH patients (p=0.13). There were no significant differences in health care utilization patterns and biochemical markers of disease, including c-reactive protein (CRP) and fecal calprotectin (FCP) (p&gt;0.05). Conclusions Prior to the pandemic, a small percentage of patients with IBD in rural SK ever used TH. A small proportion of UC patients used TH. No significant differences in disease characteristics, outcomes, or health care utilization were identified. Further study is warranted to identify barriers to use of this technology to tailor care to this patient group and improve access to care, especially now as the COVID-19 pandemic has drastically changed the use of virtual care.

AbstractTo define prognostic impact of Epstein-Barr virus (EBV) infection in diffuse large B-cell lymphoma (DLBCL), we investigated EBV status in patients with DLBCL. In all, 380 slides from paraffin-embedded tissue were available for analysis by EBV-encoded RNA-1 (EBER) in situ hybridization, and 34 cases (9.0%) were identified as EBER-positive. EBER positivity was significantly associated with age greater than 60 years (P = .005), more advanced stage (P < .001), more than one extranodal involvement (P = .009), higher International Prognostic Index (IPI) risk group (P = .015), presence of B symptom (P = .004), and poorer outcome to initial treatment (P = .006). The EBER+ patients with DLBCL demonstrated substantially poorer overall survival (EBER+ vs EBER− 35.8 months [95% confidence interval (CI), 0-114.1 months] vs not reached, P = .026) and progression-free survival (EBER+ vs EBER− 12.8 months [95% CI, 0-31.8 months] vs 35.8 months [95% CI, 0-114.1 months], respectively (P = .018). In nongerminal center B-cell–like subtype, EBER in situ hybridization positivity retained its statistical significance at the multivariate level (P = .045). Nongerminal center B-cell–like patients with DLBCL with EBER positivity showed substantially poorer overall survival with 2.9-fold (95% CI, 1.1-8.1) risk for death. Taken together, DLBCL patients with EBER in situ hybridization+ pursued more rapidly deteriorating clinical course with poorer treatment response, survival, and progression-free survival.
