A case report of pancreatic exocrine insufficiency in a patient with Parkinson's disease: A coincidence or is there more to it than meets the eye?

Pancreatic exocrine insufficiency (PEI) is an under-diagnosed condition. Untreated PEI can result in developing gastrointestinal symptoms and long-term complications including weight loss, nutrient deficiencies, sarcopenia and osteoporosis. Current best practice recommends testing for PEI in certain disorders including chronic pancreatitis, cystic fibrosis, pancreatic cancer and post-pancreatic surgery. However, there is increasing evidence that PEI is associated with a number of conditions in addition to the aforementioned diseases. These 'at-risk' conditions are a heterogeneous group of diseases, for example, diabetes mellitus, people living with human immunodeficiency virus, high alcohol intake, and coeliac disease. The pathophysiology of some of 'at-risk' conditions is becoming increasingly recognised; therefore, the list of associated conditions are in evolving process. We present a case of a 60-year-old male with Parkinson's disease and persistent abdominal pain who was found to have low faecal elastase levels indicative of severe PEI. His past medical history included none of the known risk factors for PEI. After examining the literature, we report a similar pathophysiological process underlying the development of pancreatitis and Parkinson's disease which is dysfunction of the Unfolded Protein Response. We suggest further research to assess the prevalence of PEI in the population of patients with Parkinson's disease.

Type 1 Autoimmune Pancreatitis in Europe: Clinical Profile and Response to Treatment.

BACKGROUND & AIMS: Autoimmune pancreatitis (AIP) is an immune-mediated disease of the pancreas with distinct pathophysiology and manifestations. Our aims were to characterize type 1 AIP in a large pan-European cohort and study the effectiveness of current treatment regimens. METHODS: We retrospectively analyzed adults diagnosed since 2005 with type 1 or not-otherwise-specified AIP in 42 European university hospitals. Type 1 AIP was uniformly diagnosed using specific diagnostic criteria. Patients with type 2 AIP and those who had undergone pancreatic surgery were excluded. The primary end point was complete remission, defined as the absence of clinical symptoms and resolution of the index radiologic pancreatic abnormalities attributed to AIP. RESULTS: We included 735 individuals with AIP (69% male; median age, 57 years; 85% White). Steroid treatment was started in 634 patients, of whom 9 (1%) were lost to follow-up. The remaining 625 had a 79% (496/625) complete, 18% (111/625) partial, and 97% (607/625) cumulative remission rate, whereas 3% (18/625) did not achieve remission. No treatment was given in 95 patients, who had a 61% complete (58/95), 19% partial (18/95), and 80% cumulative (76/95) spontaneous remission rate. Higher (≥0.4 mg/kg/day) corticosteroid doses were no more effective than lower (<0.4 mg/kg/day) doses (odds ratio, 0.428; 95% confidence interval, 0.054-3.387) and neither was a starting dose duration >2 weeks (odds ratio, 0.908; 95% confidence interval, 0.818-1.009). Elevated IgG4 levels were independently associated with a decreased chance of complete remission (odds ratio, 0.639; 95% confidence interval, 0.427-0.955). Relapse occurred in 30% of patients. Relapses within 6 months of remission induction were independent of the steroid-tapering duration, induction treatment duration, and total cumulative dose. CONCLUSIONS: Patients with type 1 AIP and elevated IgG4 level may need closer monitoring. For remission induction, a starting dose of 0.4 mg/kg/day for 2 weeks followed by a short taper period seems effective. This study provides no evidence to support more aggressive regimens.

Body composition parameters predict survival in pancreatic cancer-A retrospective multicenter analysis.

BACKGROUND: Parameters to adapt individual treatment strategies for patients with pancreatic ductal adenocarcinoma (PDAC) are urgently needed. The present study aimed to evaluate body composition parameters as predictors of overall survival (OS) in PDAC patients. METHODS: Measurements of body composition parameters were performed on computed tomography scans at diagnosis. Height-standardized and Body Mass Index- and sex-adjusted regression formulas deriving cut-offs from a healthy population were used. The Kaplan-Meier method with the log-rank test was performed for survival analysis. Independent prognostic factors were identified with uni- and multivariable Cox regression analyses. RESULTS: In total, 354 patients were analyzed. In a multivariable Cox model, besides tumor stage and resection status, only myosteatosis (HR 1.53; 95% CI 1.10-2.14, p = 0.01) was an independent prognostic factor of OS among body composition parameters. Subgroup analyses revealed that the prognostic impact of myosteatosis was higher in patients ≤68 years of age, with advanced tumor stages and patients without curative intended resection. CONCLUSIONS: The analysis of one of the largest Caucasian cohorts to date, demonstrated myosteatosis to be an independent prognostic factor of OS in PDAC. To improve outcomes, prospective trials aiming to investigate the utility of an early assessment of myosteatosis with subsequent intervention by dieticians, sports medicine physicians, and physiotherapists are warranted.

Chronic atrophic gastritis - An overlooked association with severe vitamin B12 deficiency: A case report and rapid review of literature.

Current guidelines recommend surveillance for gastric adenocarcinoma in patients with extensive chronic atrophic gastritis (CAG), which is considered a premalignant condition. Although the association between vitamin B12 deficiency and CAG is well described, the indication for endoscopic investigation is only advised in patients with pernicious anaemia. Our case did not have evidence of autoimmune or H. pylori infection but despite this she had CAG. We suggest considering gastroscopy for severe, unexplained vitamin B12 deficiency, particularly in this patient group.

Does reverse mentoring work in the NHS: a feasibility study of clinicians in practice.

OBJECTIVE: To assess the risks and benefits of reverse mentoring of consultants by junior doctors. DESIGN: A feasibility study divided into two phases: first a semistructured interview where performance of participating consultants was assessed by junior doctors and then a second phase allowing for feedback to be given on a one-to-one basis. Data collected through questionnaires with free text questions and Likert scores. SETTING: Tertiary teaching hospital in the UK. PARTICIPANTS: Six junior doctors (66.6% male, age range 31-40 years) and five consultants (80% male, age range 35-65 years and consultants for 5-20 years). INTERVENTION: Reverse mentoring session. MAIN OUTCOME MEASURE: The concerns and/or benefits of the process of reverse mentoring. Confidence was assessed in 7 domains: clinical practice, approach to juniors, approachability, use of technology, time management, strengths and areas for improvement using Likert scales giving a total out of 35. RESULTS: The most common concerns cited were overcoming the hierarchical difference and a selection bias in both mentors and mentees. However, no participant experienced this hierarchical difference through the reverse mentoring process and no relationships were negatively affected. Mentors became more confident in feeding back to seniors (23 vs 29 out of 35, p=0.04) most evident in clinical practice and areas to improve (3 vs 4 out of 5, p=0.041 and 3 vs 5 out of 5, p=0.041, respectively). CONCLUSION: We present the first study of reverse mentoring in an NHS clinical setting. Initial concerns with regard to damaged relationships and hierarchical gradients were not experienced and all participants perceived that they benefited from the process. Reverse mentoring can play a role in engaging and training future leaders at junior stages and provide a means for consultants to receive valuable feedback from junior colleagues.

Identification of "Digital Sarcopenia" Can Aid the Detection of Pancreatic Exocrine Insufficiency and Malnutrition Assessment in Patients with Suspected Pancreatic Pathology.

BACKGROUND: Pancreatic exocrine insufficiency (PEI) and subsequent malnutrition can be difficult to diagnose but lead to sarcopenia and increased mortality and morbidity even in benign disease. Digital skeletal muscle analysis has been increasingly recognised as a tool to diagnose sarcopenia. OBJECTIVE: The aim of the study was to assess the prevalence of sarcopenia in patients with PEI secondary to benign disease using novel skeletal muscle recognition software. METHODS: Prospective recruitment of patients referred for endoscopic ultrasound (EUS) with suspected pancreatic pathology. Patients with suspected pancreatic cancer on initial computed tomography (CT) were excluded. The diagnosis of chronic pancreatitis (CP) was based on CT and EUS findings. PEI was assessed with faecal elastase-1. Digital measurement of skeletal muscle mass identified sarcopenia, with demographic and comorbidity data also collected. RESULTS: PEI was identified in 45.1% (46/102) of patients recruited, and 29.4% (30/102) had changes of CP. Sarcopenia was significantly more prevalent in PEI 67.4% (31/46) than no-PEI 37.5% (21/56) (37.5%), regardless of CP changes (p < 0.003). The prevalence of sarcopenia (67% vs. 35%; p = 0.02) and sarcopenic obesity (68.4% vs. 25%; p = 0.003) was significantly higher when PEI was present without a radiological diagnosis of CP. Multivariate analysis identified sarcopenia and diabetes to be independently associated with PEI (odds ratio 4.8 and 13.8, respectively, p < 0.05). CONCLUSION: Sarcopenia was strongly associated with PEI in patients undergoing assessment for suspected benign pancreatic pathology. Digital skeletal muscle assessment can be used as a tool to aid identification of sarcopenia in patients undergoing CT scan for pancreatic symptoms.

Computed Tomographic Sarcopenia in Pancreatic Cancer: Further Utilization to Plan Patient Management.

PURPOSE: The presence of a sarcopenia adversely affects the prognosis of patients with pancreatic cancer. There is an emerging role for using computed tomography (CT) to calculate skeletal muscle index (SMI) and the presence of sarcopenia. The aim of this study was to assess if detecting 'computed tomographic sarcopenia' is feasible and can contribute to the management of patients with locally advanced pancreatic cancer (LAPC). METHODS: Patients diagnosed with LAPC referred for endoscopic ultrasound-guided biopsy (EUS-B) by our regional cancer network were identified. Age, body mass index (BMI), and Eastern Cooperative Oncology Group performance status (ECOG-PS) were noted. CT images were analysed for SMI and the presence of sarcopenia. Decision outcomes on receiving chemotherapy or not were collected from the regional oncology database. RESULTS: In total, 51/204 (25%) patients with LAPC who underwent EUS-B were not given chemotherapy and received best supportive care (BSC) only. The prevalence of sarcopenia (p = 0.0003), age ≥ 75 years old (p = 0.03), and ECOG-PS 2-3 (p = 0.01) were significantly higher in the patients receiving BSC only. Logistic regression analysis demonstrated that SMI was the only independent associated factor identifying patients with LAPC who were treated with BSC only and not chemotherapy after adjusting for age and ECOG-PS. CONCLUSION: Our study has shown that computed tomographic skeletal muscle analysis at the time of a diagnostic CT for patients with pancreatic cancer is feasible and can detect sarcopenia and malnourished patients who are much less likely to take up chemotherapy. These patients could be triaged to oncology assessment prior to EUS-B to avoid unnecessary investigations.

Experiences of using vedolizumab in the treatment of inflammatory bowel disease in the East Midlands UK - a retrospective observational study.

PURPOSE: Clinical trials have demonstrated efficacy of vedolizumab in ulcerative colitis (UC) and Crohn's disease (CD). Further real-world data is needed to inform clinical practice. The primary outcome was to assess corticosteroid-free and clinical remission after vedolizumab initiation. Secondary outcomes included effect on disease activity scores, biochemical markers, concomitant drug use, endoscopic remission, surgical intervention, hospital admissions and adverse events. MATERIALS AND METHODS: A multi-centre retrospective observational study was conducted with patients initiated on vedolizumab across seven UK hospitals 1/11/14-30/11/16. Clinical disease activity was assessed using the partial Mayo Scores (pMS) and Harvey Bradshaw Index (HBI). Clinical remission was defined as HBI ≤4 or pMS <2 with a combined stool frequency and rectal bleeding sub score of ≤1. Clinical response was defined as ≥2-point decrease from baseline in pMS and ≥3-point decrease from baseline in HBI. RESULTS: One hundred ninety-two patients were included in the final analysis. 45% of UC and 10% of CD patients were anti-TNF naive. Over the observation period corticosteroid-free remission rates for UC and CD were 46% and 45%, while clinical remission rates were 52% and 44%, respectively. Time to corticosteroid free remission for UC and CD was 17.6 [IQR: 8.7-29.6] and 14.1 [QR: 6.0-21.7] weeks, respectively. Time to clinical response for UC was 9.4 [IQR: 5.7-15.4] and CD was 9.5 [IQR: 6.1-18.2] weeks. There was a substantial decrease in the concomitant use of immunomodulators and a similar decrease in concomitant corticosteroid use over the study period. CONCLUSIONS: Results in this predominately anti-TNF experienced population mirror other published real-world data, demonstrating good clinical effectiveness and a comparable safety profile.

Recent advances in the diagnosis and management of pancreatic neuroendocrine tumours.

The incidence of pancreatic neuroendocrine tumours (PNET) is rising mainly due to the increased use of cross-sectional imaging. Although many PNETs are asymptomatic and non-functioning, the overall 5-year survival is still less than 50%. In this article, we review the advances in diagnosis, classification and staging of PNET that have evolved with the development of new cross-sectional imaging methods and biopsy techniques. With accurate classification, evidence-based, individualised prognostic outcomes and treatments are able to be given which are also discussed.
