Abstract
BACKGROUND/OBJECTIVES Disconnectedpancreatic duct syndrome (DPDS), a severe complication of acute necrotizing pancreatitis (ANP), may require surgery, usually by distal splenopancreatectomy, thus increasing the risk of diabetes. We describe a new technique reconnecting the distal pancreas to the digestive tract. METHODS This technique was proposed after failure of non-surgical treatment and at least 3 months after the onset of ANP in non-diabetic or non-insulin dependent diabetic patients with a distal pancreas of at least 5 cm. The ruptured zone was identified and the distal side was anastomosed to the stomach or the jejunum. RESULTS From 2013 to June 2019, 36 patients (median age = 49 years) with DPDS underwent a "French reconnection" procedure, indicated for chronic pain/recurrent pancreatitis (n = 35; 97%), persistent pancreatic fistula (n = 33; 91%), or digestive compression/fistulisation (n = 9; 25%). Median preoperative weight loss was 10 kg (4-27), the median number of hospitalisations per patient was 5(1-8) and 24(67%) patients had received endoscopic/percutaneous treatment. Surgery was performed in median 279(90-2000) days after ANP, laparoscopically in 9(25%) patients. The remnant pancreas (median length = 70 mm; range = 50-130) was anastomosed to the stomach (n = 30) or the jejunum (n = 6). There were 13(36%) postoperative grade B/C pancreatic fistulas and 3(10%) bleedings including one death (mortality = 3%). The median hospital stay was 18 (7-121) days. After a median follow-up of 24 (4-53) months, all pancreatic fistulas had healed and the clinical success rate was 91%. Median BMI increased from 22 to 25 kg/m2. In patients with normal pancreatic function, postoperative de novo endocrine and severe exocrine insufficiencies were observed in 4/27 (15%) and 7/22 (32%), respectively. CONCLUSIONS The "French reconnection" procedure, as an alternative to distal splenopancreatectomy for the treatment of DPDS, provides good control of symptoms and decreases the risk of pancreatic insufficiency.

Abstract
BACKGROUND The ABO blood group may influence the development and progression of cancer. In particular, the prognosis of patients with blood type O is better for pancreatic adenocarcinoma, although this has not been extensively explored in pancreatic neuroendocrine tumors (PanNET). OBJECTIVE To assess the influence of the ABO and Rhesus blood types on the risk of recurrence in patients who underwent curative intent PanNET surgical resection. METHODS All consecutive patients operated on for well-differentiated panNET in an expert center from 2003 to 2018 were retrospectively included. Blood group, Rhesus system, demographic and clinical data were collected. The primary endpoint was recurrence free survival (RFS). Factors associated with RFS were explored using Cox proportional hazard models. RESULTS Overall, 300 patients (male 43%) were included, median age 54 years old (IQR 45-64). The ABO blood group distribution was similar to that of the French population. There was no association between blood group and tumor features. The median postoperative follow-up was 43.9 months (17.0-77.8). The 5- and 10-year RFS rates were 85 ± 4% and 71 ± 13% in O RhD + patients, versus 72 ± 4% and 63 ± 6% otherwise, respectively (p = 0.035). The O RhD + blood group was associated with a decreased risk of recurrence (HR 0.34, 95% CI [0.15-0.75]), p = 0.007 in multivariable analysis adjusted for age, ki67, functioning syndrome, resection margins, tumor size, lymph node status, oncogenetic syndrome. CONCLUSIONS After curative-intent surgical resection for PanNET, patients with a non-O RhD + blood group may have an increased risk of recurrence and could benefit from closer follow-up.

Abstract
OBJECTIVE To identify predictive factors of unfavourable outcome among patients hospitalized for COVID-19. METHODS We conducted a monocentric retrospective cohort study of COVID-19 patients hospitalized in Paris area. An unfavourable outcome was defined as the need for artificial ventilation and/or death. Characteristics at admission were analysed to identify factors predictive of unfavourable outcome using multivariable Cox proportional hazard models. Based on the results, a nomogram to predict 14-day probability of poor outcome was proposed. RESULTS Between March 15th and April 14th, 2020, 279 COVID-19 patients were hospitalized after a median of 7 days after the first symptoms. Among them, 88 (31.5%) patients had an unfavourable outcome: 48 were admitted to the ICU for artificial ventilation, and 40 patients died without being admitted to ICU. Multivariable analyses retained age, overweight, polypnoea, fever, high C-reactive protein, elevated us troponin-I, and lymphopenia as risk factors of an unfavourable outcome. A nomogram was established with sufficient discriminatory power (C-index 0.75), and proper consistence between the prediction and the observation. CONCLUSION We identified seven easily available prognostic factors and proposed a simple nomogram for early detection of patients at risk of aggravation, in order to optimize clinical care and initiate specific therapies. KEY MESSAGES Since novel coronavirus disease 2019 pandemic, a minority of patients develops severe respiratory distress syndrome, leading to death despite intensive care. Tools to identify patients at risk in European populations are lacking. In our series, age, respiratory rate, overweight, temperature, C-reactive protein, troponin and lymphocyte counts were risk factors of an unfavourable outcome in hospitalized adult patients. We propose an easy-to-use nomogram to predict unfavourable outcome for hospitalized adult patients to optimize clinical care and initiate specific therapies.

CT-Based Radiomics Analysis to Predict Malignancy in Patients with Intraductal Papillary Mucinous Neoplasm (IPMN) of the Pancreas. Cancers (Basel) 2020; 12:cancers12113089. [PMID: 33114028 PMCID: PMC7690711 DOI: 10.3390/cancers12113089] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 10/17/2020] [Accepted: 10/21/2020] [Indexed: 02/07/2023] Open
Abstract
To assess the performance of CT-based radiomics analysis in differentiating benign from malignant intraductal papillary mucinous neoplasms of the pancreas (IPMN), preoperative scans of 408 resected patients with IPMN were retrospectively analyzed. IPMNs were classified as benign (low-grade dysplasia, n = 181), or malignant (high grade, n = 128, and invasive, n = 99). Clinicobiological data were reported. Patients were divided into a training cohort (TC) of 296 patients and an external validation cohort (EVC) of 112 patients. After semi-automatic tumor segmentation, PyRadiomics was used to extract radiomics features. A multivariate model was developed using a logistic regression approach. In the training cohort, 85/107 radiomics features were significantly different between patients with benign and malignant IPMNs. Unsupervised clustering analysis revealed four distinct clusters of patients with similar radiomics features patterns with malignancy as the most significant association. The multivariate model differentiated benign from malignant tumors in TC with an area under the ROC curve (AUC) of 0.84, sensitivity (Se) of 0.82, specificity (Spe) of 0.74, and in EVC with an AUC of 0.71, Se of 0.69, Spe of 0.57. This large study confirms the high diagnostic performance of preoperative CT-based radiomics analysis to differentiate between benign from malignant IPMNs.

Abstract
The efficacy of alkylating agents (temozolomide, dacarbazine, streptozotocin) in patients with advanced neuroendocrine tumors (NETs) has been well documented, especially in pancreatic NETs. Alkylating agents transfer methyl adducts on DNA bases. Among them, O6-methylguanine accounts for many of their cytotoxic effects and can be repaired by the O6-methylguanine-methyltransferase (MGMT). However, whether the tumor MGMT status could be a reliable biomarker of efficacy of alkylating agents in NETs is still a matter of debate. Herein, we sought to provide a critical appraisal of the role of the MGMT status in NETs. After reviewing the molecular mechanisms of repair of DNA damage induced by alkylating agents, we aimed to comprehensively review the methods of determination of the MGMT status and its impact on prognosis, prediction of objective response and progression-free survival in patients with advanced digestive NETs treated by alkylating agents. About half of pancreatic NETs are MGMT-deficient, as determined by impaired tumor MGMT expression or by MGMT promoter methylation. Overall, while published studies are heterogeneous and mostly limited in size, they advocate that MGMT deficiency may be a relevant biomarker for increased objective response rate, prolonged progression-fee survival and overall survival in patients with advanced NETs treated by alkylating agents. While these data require confirmation in prospective controlled studies, future research should focus on the standardization of MGMT status assessment. Additional mechanisms of repair of DNA damages induced by alkylating agents should be explored in order to identify biomarkers complementary to MGMT and targets for potential antitumor synergy, such as PARP.

Abstract
Since the description of the SPINK1 gene encoding the serine protease inhibitor Kazal type 1 and the CTRC gene encoding the Chymotrypsin C as being involved in chronic pancreatitis, more than 56 SPINK1 and 87 CTRC variants have been reported. Assessing the clinical relevance of SPINK1 and CTRC variants is often complicated in the absence of functional evidence and interpretation of rare variants is not very easy in clinical practice. The aim of this study was to review the different variants identified in these two genes and to classify them according to their degree of damaging effect. This classification was based on the results of in vitro experiments, in silico analysis using different prediction tools, and on population data, in comparing the allelic frequency of each variant in patients with pancreatitis and in unaffected control individuals. This review should help geneticists and clinicians in charge of patient's care and genetic counseling to interpret the results of genetic studies.

Abstract
BACKGROUND The G-protein-coupled receptor Class C Group 6 Member A (GPRC6A) is activated by multiple ligands and is important for the regulation of calcium homeostasis. Extracellular calcium is capable to increase NLRP3 inflammasome activity of the innate immune system and deletion of this proinflammatory pathway mitigated pancreatitis severity in vivo. As such this pathway and the GPRC6A receptor is a reasonable candidate gene for pancreatitis. Here we investigated the prevalence of sequence variants in the GPRC6A locus in different pancreatitis aetiologies. METHODS We selected 6 tagging SNPs with the SNPinfo LD TAG SNP Selection tool and the functional relevant SNP rs6907580 for genotyping. Cohorts from Germany, further European countries and China with up to 1,124 patients and 1,999 controls were screened for single SNPs with melting curve analysis. RESULTS We identified an association of rs1606365(G) with alcoholic chronic pancreatitis in a German (odds ratio (OR) 0.76, 95% confidence interval (CI) 0.65-0.89, p = 8 × 10-5) and a Chinese cohort (OR 0.78, 95% CI 0.64-0.96, p = 0.02). However, this association was not replicated in a combined cohort of European patients (OR 1.18, 95% CI 0.99-1.41, p = 0.07). Finally, no association was found with acute and non-alcoholic chronic pancreatitis. CONCLUSIONS Our results support a potential role of calcium sensing receptors and inflammasome activation in alcoholic chronic pancreatitis development. As the functional consequence of the associated variant is unclear, further investigations might elucidate the relevant mechanisms.

Abstract
BACKGROUND Gastrointestinal bleeding is a rare but severe complication of pancreatic ductal adenocarcinoma. OBJECTIVE The purpose of this study was to describe the causes and treatments of non-postoperative gastrointestinal bleeding in patients with pancreatic ductal adenocarcinoma, and explore the parameters associated with therapeutic effectiveness. METHODS This was a single-centre observational retrospective study (2000-2017) with data collected from the prospectively coded diagnostic hospital's database system including patients with pancreatic ductal adenocarcinoma who had a gastrointestinal bleeding episode. Effectiveness of haemostatic treatment was assessed according to transfusion requirements and immediate and long-term haemostatic efficacy; the latter defined as no bleeding recurrence. RESULTS The population included 72 patients with pancreatic ductal adenocarcinoma who had 94 episodes of gastrointestinal bleeding. The main causes of gastrointestinal bleeding were gastroduodenal tumour invasion (56.4%) and oesophageal variceal bleeding due to left-sided portal hypertension (19.1%). In cases of gastrointestinal bleeding caused by tumour invasion, the main treatment was therapeutic endoscopy (41.5%). Among patients who had gastrointestinal bleeding by tumour invasion treated by endoscopy or radiation therapy, haemostatic immediate efficacy rates were 70.6% and 100%, respectively. Bleeding recurrence rates were 35.3% and 25.0%, for patients treated by endoscopy or radiation therapy, respectively, for a first episode of gastrointestinal bleeding by tumour invasion. Transfusion requirements, before and after treatment, were not different in patients treated by haemostatic radiation therapy for gastrointestinal bleeding by tumour invasion compared to other treatments (odds ratio 0.3, 95% CI (0.06-1.59); p = 0.16). The median survival after all-cause gastrointestinal bleeding was 2.72 months (1.43-4.01). CONCLUSION Gastroduodenal tumour invasion was the main cause of gastrointestinal bleeding in patients with pancreatic ductal adenocarcinoma; haemostatic radiation therapy is a potential interesting option for gastrointestinal bleeding treatment in this context.

Abstract
BACKGROUND Patients with chronic pancreatitis (CP) have an increased risk of pancreatic cancer. We present the international consensus guidelines for surveillance of pancreatic cancer in CP. METHODS The international group evaluated 10 statements generated from evidence on 5 questions relating to pancreatic cancer in CP. The GRADE approach was used to evaluate the level of evidence available per statement. The working group voted on each statement for strength of agreement, using a nine-point Likert scale in order to calculate Cronbach's alpha reliability coefficient. RESULTS In the following domains there was strong consensus: (1) the risk of pancreatic cancer in affected individuals with hereditary pancreatitis due to inherited PRSS1 mutations is high enough to justify surveillance; (2) the risk of pancreatic cancer in patients with CP associated with SPINK1 p. N34S is not high enough to justify surveillance; (3) surveillance should be undertaken in pancreatic specialist centers; (4) surveillance should only be introduced after the age of 40 years and stopped when the patient would no longer be suitable for surgical intervention. All patients with CP should be advised to lead a healthy lifestyle aimed at avoiding risk factors for progression of CP and pancreatic cancer. There was only moderate or weak agreement on the best methods of screening and surveillance in other types of environmental, familial and genetic forms of CP. CONCLUSIONS Patients with inherited PRSS1 mutations should undergo surveillance for pancreatic cancer, but the best methods for cancer detection need further investigation.

Abstract
The overall objective of these guidelines is to provide evidence-based recommendations for the diagnosis and management of immunoglobulin G4 (IgG4)-related digestive disease in adults and children. IgG4-related digestive disease can be diagnosed only with a comprehensive work-up that includes histology, organ morphology at imaging, serology, search for other organ involvement, and response to glucocorticoid treatment. Indications for treatment are symptomatic patients with obstructive jaundice, abdominal pain, posterior pancreatic pain, and involvement of extra-pancreatic digestive organs, including IgG4-related cholangitis. Treatment with glucocorticoids should be weight-based and initiated at a dose of 0.6-0.8 mg/kg body weight/day orally (typical starting dose 30-40 mg/day prednisone equivalent) for 1 month to induce remission and then be tapered within two additional months. Response to initial treatment should be assessed at week 2-4 with clinical, biochemical and morphological markers. Maintenance treatment with glucocorticoids should be considered in multi-organ disease or history of relapse. If there is no change in disease activity and burden within 3 months, the diagnosis should be reconsidered. If the disease relapsed during the 3 months of treatment, immunosuppressive drugs should be added.

Abstract
BACKGROUND Chronic pancreatitis (CP) is a complex inflammatory disease with remarkably impaired quality of life and permanent damage of the pancreas. This paper is part of the international consensus guidelines on CP and presents the consensus on factors elevating the risk for CP. METHODS An international working group with 20 experts on CP from the major pancreas societies (IAP, APA, JPS, and EPC) evaluated 14 statements generated from evidence on four questions deemed to be the most clinically relevant in CP. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to evaluate the level of evidence available per statement. To determine the level of agreement, the working group voted on the 14 statements for strength of agreement, using a nine-point Likert scale in order to calculate Cronbach's alpha reliability coefficient. RESULTS Strong consensus and agreement were obtained for the following statements: Alcohol, smoking, and certain genetic alterations are risk factors for CP. Past history, family history, onset of symptoms, and life-style factors including alcohol intake and smoking history should be determined. Alcohol consumption dose-dependently elevates the risk of CP up to 4-fold. Ever smokers, even smoking less than a pack of cigarettes per day, have an increased risk for CP, as compared to never smokers. CONCLUSIONS Both genetic and environmental factors can markedly elevate the risk for CP. Therefore, health-promoting lifestyle education and in certain cases genetic counselling should be employed to reduce the incidence of CP.

Abstract
The diagnosis and treatment of pancreatic and biliary tract involvement in IgG4 disease can be challenging for physicians. A French series shows that the pancreas is the most frequently involved organ in systemic IgG4 disease. Pancreatitis may be found in more than 50% of patients with IgG4 disease and the biliary tract is involved in one third. Pancreatic or biliary involvement may be isolated, metachronous or synchronous of other IgG4-related organ injuries. Pancreatitis related to IgG4 disease is called autoimmune pancreatitis (AIP) type 1. The diagnosis is mainly suspected in the presence of symptoms and morphological features. Changes observed on conventional imaging are not typical and are usually similar to lesions observed in autoimmune pancreatitis type 2. AIP type 1 can also sometimes have a clinical or morphological presentation that mimics pancreatic cancer, especially pseudo-tumoral forms, associated with obstructive jaundice, weight loss and fatigue. Thus, the first challenge is to confirm the diagnosis of autoimmune pancreatitis and to exclude cancer. The AIP type must then be determined to decide on the most appropriate treatment.

Abstract
INTRODUCTION The goal of this retrospective study was to investigate the potential link between diabetes mellitus (DM) and the recurrence of pancreatic neuroendocrine tumors (PanNET) following curative intent surgery. METHODS We included patients who underwent surgical resection of nonmetastatic well-differentiated PanNET. Exacerbation of DM was defined as the postoperative occurrence of DM or worsening of preexisting DM. We explored the variables associated with PanNET recurrence-free survival (RFS). RFS was compared in a subset of patients with and without DM operated on by anatomical resection, after matching for the main prognostic factors. The impact of antidiabetic therapy on RFS was assessed. RESULTS A total of 268 patients (median age 54.7, 40% men) were included. Most PanNET were sporadic (85%), G1 (61%), pT1/pT2 (79%), and pN0 (76%). Postoperative DM exacerbation occurred in 38 patients (14%), including 27 with new-onset DM. On multivariable analysis, DM exacerbation was independently associated with an increased risk of PanNET recurrence (HR 2.35, 95% CI [1.24-4.47], p = 0.009) after adjustment for age, multiplicity of tumors, grade, pT, and pN stages. Similar results were found when 27 patients with and 48 patients without DM exacerbation, matched for grade, pT stage and pN stage, were compared (HR 3.03, 95% CI [1.05-8.77], p = 0.032). The postoperative use of metformin tended to decrease the risk of recurrence (HR 0.59, 95% CI 0.24-1.47, p = 0.26). CONCLUSION Patients with postoperative DM exacerbation may have an increased risk of PanNET recurrence. Closer follow-up might be beneficial in these patients. The protective role of metformin should be further explored.

Abstract
Four epidemiologic studies have assessed the association between nut intake and pancreatic cancer risk with contradictory results. The present study aims to investigate the relation between nut intake (including seeds) and pancreatic ductal adenocarcinoma (PDAC) risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Cox proportional hazards models were used to estimate hazards ratio (HR) and 95% confidence intervals (95% CI) for nut intake and PDAC risk. Information on intake of nuts was obtained from the EPIC country-specific dietary questionnaires. After a mean follow-up of 14 years, 476,160 participants were eligible for the present study and included 1,283 PDAC cases. No association was observed between consumption of nuts and PDAC risk (highest intake vs nonconsumers: HR, 0.89; 95% CI, 0.72-1.10; p-trend = 0.70). Furthermore, no evidence for effect-measure modification was observed when different subgroups were analyzed. Overall, in EPIC, the highest intake of nuts was not statistically significantly associated with PDAC risk.

Abstract
BACKGROUND Ki67 proliferation index and tumor uptake on 18fluorodeoxyglucose positron-emitting tomography (FDG-PET) could be correlated in pancreatic neuroendocrine tumors (PanNET), but the evaluation of the former is subject to tumor heterogeneity. AIMS Explore the correlation between Ki67 and FDG-PET uptake at the lesion scale in PanNET. METHODS We identified target lesions ≥10 mm in patients operated on for a PanNET and/or associated metastases with preoperative FDG-PET and without neoadjuvant treatment. We assessed the lesion-by-lesion correlation between Ki67 and the tumor-to-liver SUVmax ratio (SUVmax T/L), and between pathological grade (G) and metabolic grade (mG) (mG1, SUVmax T/L ≤ 1, mG2, SUVmax T/L 1-2.3 and mG3, SUVmax T/L > 2.3). RESULTS Twenty-one patients underwent pancreatic (n = 12), liver (n = 2) or combined surgery (n = 7). Overall, 36 target lesions (21 primary PanNET, 13 liver metastases and 2 lymph-node metastases) were identified, of median Ki67 4%. Ki67 correlated with SUVmax T/L (r = 0.55, p < 0.001). Median SUVmax T/L was 0.76, 1.41 and 2.67 for lesions G1, G2 and G3, respectively (p = 0.005). Median Ki67 was 1, 4 and 25 for lesions mG1, mG2 and mG3, respectively (p = 0.005). CONCLUSIONS Uptake on FDG-PET could predict the pathological grade of PanNET lesions. Hence, FDG-PET could supplement pathological evaluation of tumor biological aggressiveness and could guide the choice of the most relevant lesions to biopsy.

Abstract
BACKGROUND The aim was to describe genetic, clinical and morphological features in a large, multicentre European cohort of patients with SPINK1 related pancreatitis, in comparison with patients with idiopathic pancreatitis (IP). METHODS All SPINK1 mutation carriers with pancreatic symptoms from two French and one English centers were included. Patients with IP were included in a control group. Genetic, clinical, radiological and biochemical data were collected. FINDINGS 209 and 302 patients were included in the SPINK1 and control groups (median follow-up: 8.3 years (3.7-17.4) vs 5.3 (2.5-8.8)). The median age at onset of symptoms was 20.1 years (17.5-22.8) in the SPINK1 group versus 41.2 (35.2-45.2). The age of exocrine pancreatic insufficiency (EPI) onset in the SPINK1 group was 49.5 (44.5-54.6) years vs. 65.2 (62.1-68.3), p < 0.001. SPINK1 patients with EPI were 5.3%, 14.7%, 28.3% and 52.4% at 20, 30, 40 and 50 years. Diabetes occurred 37.7 (33.3-42.1) years following the onset of symptoms in the SPINK1 group vs. 30.6 (17.3-43.8) (p = 0.002). SPINK1 patients with diabetes were 7.8%, 13.4%, 26.3% and 43.4% at 30, 40, 50 and 60 years. Seven patients (3.3%) developed pancreatic cancer in the SPINK1 group (versus 3 (0.99%), p = 0.1), at a median age of 60 vs 66 years. The cancer risk was 0.8% before 50 years, 11.9%, 27.7%, 51.8% at 60, 70 and 80 years and was 12 times higher than in controls (Cox HR 12.0 (3.0-47.8), p < 0.001). INTERPRETATION SPINK1 related pancreatitis is associated with earlier onset and pancreatic insufficiencies. p.N34S SPINK1 may well be associated with cancer.

Adherence to a healthy lifestyle was inversely associated with PC risk, beyond the beneficial role of smoking avoidance. Public health measures targeting compliance with healthy lifestyles may have an impact on PC incidence.

Abstract
Managing familial pancreatic cancer (FPC) is challenging for gastroenterologists, surgeons and oncologists. High-risk individuals (HRI) for pancreatic cancer (PC) (FPC or with germline mutations) are a heterogeneous group of subjects with a theoretical lifetime cumulative risk of PC over 5%. Screening is mainly based on annual magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS). The goal of screening is to identify early-stage operable cancers or high-risk precancerous lesions (pancreatic intraepithelial neoplasia or intraductal papillary mucinous neoplasms with high-grade dysplasia). In the literature, target lesions are identified in 2%-5% of HRI who undergo screening. EUS appears to provide better identification of small solid lesions (0%-46% of HRI) and chronic-pancreatitis-like parenchymal changes (14%-77% of HRI), while MRI is probably the best modality to identify small cystic lesions (13%-49% of HRI). There are no specific studies in HRI on the use of contrast-enhanced harmonic EUS. EUS can also be used to obtain tissue samples. Nevertheless, there is still limited evidence on the accuracy of imaging procedures used for screening or agreement on which patients to treat. The cost-effectiveness of screening is also unclear. Certain new EUS-related techniques, such as searching for DNA abnormalities or protein markers in pancreatic fluid, appear to be promising.

Abstract
Background and aims Steroid therapy is the first-line treatment for autoimmune pancreatitis but relapses are frequent. The aims were to assess the efficacy and the safety of immunomodulator treatments for relapsing autoimmune pancreatitis and rituximab in particular and to identify relapsing risk factors. Methods Patients followed for autoimmune pancreatitis from 2000 to 2016 were included. Data were retrospectively analysed regarding autoimmune pancreatitis treatment. Results In total, 162 patients with autoimmune pancreatitis type 1 (n = 92) and type 2 (n = 70) were included (median follow-up: 3 years (0.5-14). Relapse occurred in 46.5% of patients with autoimmune pancreatitis type 1 (vs 19.3% in autoimmune pancreatitis 2; p < 0.001). Risk factors of relapse were cholangitis, initial use of steroids, other organ involvement and chronic pancreatitis in autoimmune pancreatitis type 1 and initial use of steroids, tobacco consumption and chronic pancreatitis for autoimmune pancreatitis type 2. Overall, 21 patients were treated with immunomodulators (azathioprine, n = 19, or methotrexate, n = 2) for relapses. The efficiency rate was 67%. A total of 17 patients were treated with rituximab, with two perfusions at 15 days apart. The efficacy was 94% (16/17), significantly better than immunomodulator drugs (p = 0.03), with a median follow-up of 20 months (11-44). Only two patients needed two supplementary perfusions. Conclusion In relapsing autoimmune pancreatitis, rituximab is more efficient than immunomodulator drugs and shows better tolerance.

Abstract
BACKGROUND To analyze the potential effect of social inequality on pancreatic cancer risk in Western Europe, by reassessing the association within the European Prospective Investigation into Cancer and Nutrition (EPIC) Study, including a larger number of cases and an extended follow-up. METHODS Data on highest education attained were gathered for 459,170 participants (70% women) from 10 European countries. A relative index of inequality (RII) based on adult education was calculated for comparability across countries and generations. Cox regression models were applied to estimate relative inequality in pancreatic cancer risk, stratifying by age, gender, and center, and adjusting for known pancreatic cancer risk factors. RESULTS A total of 1,223 incident pancreatic cancer cases were included after a mean follow-up of 13.9 (±4.0) years. An inverse social trend was found in models adjusted for age, sex, and center for both sexes [HR of RII, 1.27; 95% confidence interval (CI), 1.02-1.59], which was also significant among women (HR, 1.42; 95% CI, 1.05-1.92). Further adjusting by smoking intensity, alcohol consumption, body mass index, prevalent diabetes, and physical activity led to an attenuation of the RII risk and loss of statistical significance. CONCLUSIONS The present reanalysis does not sustain the existence of an independent social inequality influence on pancreatic cancer risk in Western European women and men, using an index based on adult education, the most relevant social indicator linked to individual lifestyles, in a context of very low pancreatic cancer survival from (quasi) universal public health systems. IMPACT The results do not support an association between education and risk of pancreatic cancer.
