[Results of pancreatic surgery from the perspective of patients: a cross-sectional study of the support group "Arbeitskreis der Pankreatektomierten e. V."] / Ergebnisse nach Pankreaseingriffen aus Sicht der Betroffenen: Versorgungsforschung der Selbsthilfegruppe "Arbeitskreis der Pankreatektomierten e. V.".

BACKGROUND: The support group "Arbeitskreis der Pankreatektomierten e. V. (AdP)" was founded in 1976 and is the largest group of individuals affected by pancreatic disease in Germany. Members of the AdP support patients with pancreatic disease. This patient-initiated, cross-sectional study intends to present the results of pancreatic surgery from the perspective of patients. METHODS: Since March the 3 rd, 2018, members of the AdP received a questionnaire with eleven categories of questions concerning their medical history. This data was gathered in a medical database and analysed. RESULTS: 625 members were operated upon, with 57.5 % receiving pancreaticoduodenectomy, 15.5 % distal pancreatectomy, 23.2 % total pancreatectomy, and 4.0 % another or unknown operation. 37.9 % were diagnosed with pancreatic cancer, 38.2 % with another type of pancreatic tumour, 25 % with pancreatitis, 4 % with autoimmune pancreatitis and 2.7 % with other rare entities.82 patients of 237 pancreatic cancer patients survived more than 5 years. 24.5 % of the 237 patients reported have a second primary malignancy and 13.9 % have close family members with pancreatic cancer.Weight loss after pancreatic surgery was dependant on the type of operation with the greatest after pancreatectomy (17.8 ±â€Š9.5 kg). The prevalence of diabetes was 54.1 %, the incidence of new onset perioperative diabetes 33.3 %. 91.5 % needed pancreatic enzyme replacement therapy, on average 189 417 IE/day. The reported quality of life was independent from type of surgery received. CONCLUSION: Following complex pancreatic surgery, patients are confronted with daily lifelong challenges. AdP members offering their shared experiences offer meaningful support to newly affected patients. Individuals affected by pancreatic disease could be an important but underutilised resource to studying these diseases.

Refractory neutrophil activation in type 2 diabetics with chronic periodontitis.

BACKGROUND: Inflammation increases diabetes mellitus type 2 (T2DM) progression and severity. T2DM patients are at high risk of the rapid development of chronic periodontitis (CP). Topical presence, high numbers, and bactericidal effects of immune cells are challenged by augmented antigen-induced inflammation, which promotes both diseases. OBJECTIVES: To investigate gingival cellular inflammatory responses in individuals with previously undiagnosed T2DM with CP or CP alone and in systemically and periodontally healthy controls (H) in vivo and to establish an ex vivo technique permitting quantitative and qualitative assessments of gingival crevicular immune cells. MATERIALS AND METHODS: T2DM + CP, CP, and H individuals (n = 10, each) received a 2-week oral hygiene regimen (OHR). Afterwards, a noninvasive sampling technique was performed to evaluate gingival inflammation induced under standardized conditions in vivo, that is, in the absence of severe periodontal destruction and inflammation at clinically healthy sites. Stimuli (casein/test or phosphate-buffered saline w/o. Ca2+ or Mg2+ , PBS(-/-) /control) were randomly applied contralaterally in the gingival sulci of participants' upper dentes canini. One day after completion of the OHR, gingival crevicular fluid (GCF) was kinetically assayed between the time of the baseline (BL) measurement and 55 minutes. Polymorphonuclear leukocyte (PMN) content (PMNGCF ) was quantitated at an optimum time of 35 minutes. PMNGCF counts reflect local inflammation. Ex vivo samples were fluorimetrically labeled, gated according to the donor's peripheral blood polymorphonuclear neutrophils (PMNPB ), and then counted, employing flow cytometry. RESULTS: PMNGCF counts in unstimulated gingival crevices (at BL) in the T2DM + CP group were higher than those in the CP and H groups. PMNGCF counts were elevated in casein vs PBS(-/-) -stimulated gingival crevices in all groups. Patients with T2DM + CP showed increased PMNGCF counts compared to those with CP (P = .035) according to scatter plots. CD45+ counts in the stimulated sites in T2DM + CP patients were higher than those in CP and H patients (P = .041). Under stimulation conditions, the CD45+ counts differed from those under placebo conditions (P = .019), indicating augmented, inducible inflammatory leukocyte infiltrate in T2DM + CP patients. CONCLUSIONS: This noninvasive technique permits quantitative assessment of (experimental) gingival inflammation in vivo, revealing an influence of T2DM + CP on the number of primary immune cells in the gingival crevice. Patients who are challenged with (local) leukocytosis are likely at risk of collateral damage to the gingival crevice neighboring tissues, favoring the severity and progression of CP and consequently T2DM (www.clinicaltrials.gov NCT01848379).

Recommendations from the United European Gastroenterology evidence-based guidelines for the diagnosis and therapy of chronic pancreatitis.

BACKGROUND: In collaboration with United European Gastroenterology, the working group on 'Harmonizing diagnosis and treatment of chronic pancreatitis across Europe' (HaPanEU) developed European guidelines for the management of chronic pancreatitis using an evidence-based approach. METHODS: Recommendations of multidisciplinary review groups based on systematic literature reviews to answer predefined clinical questions are summarised. Recommendations are graded using the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS: Recommendations covered topics related to the clinical management of chronic pancreatitis: aetiology, diagnosis of chronic pancreatitis with imaging, diagnosis of pancreatic exocrine insufficiency, surgical therapy, medical therapy, endoscopic therapy, treatment of pancreatic pseudocysts, pancreatic pain, nutrition and malnutrition, diabetes mellitus and the natural course of the disease and quality of life. CONCLUSIONS: The HaPanEU/United European Gastroenterology guidelines provide evidence-based recommendations concerning key aspects of the medical and surgical management of chronic pancreatitis based on current available evidence. These recommendations should serve as a reference standard for existing management of the disease and as a guide for future clinical research. This article summarises the HaPanEU recommendations and statements.

Mechanisms linking hypertriglyceridemia to acute pancreatitis.

Hypertriglyceridemia (HTG) is a metabolic disorder, defined when serum or plasma triglyceride concentration (seTG) is >1.7 mM. HTG can be categorized as mild to very severe groups based on the seTG value. The risk of acute pancreatitis (AP), a serious disease with high mortality and without specific therapy, increases with the degree of HTG. Furthermore, even mild or moderate HTG aggravates AP initiated by other important etiological factors, including alcohol or bile stone. This review briefly summarizes the pathophysiology of HTG, the epidemiology of HTG-induced AP and the clinically observed effects of HTG on the outcomes of AP. Our main focus is to discuss the pathophysiological mechanisms linking HTG to AP. HTG is accompanied by an increased serum fatty acid (FA) concentration, and experimental results have demonstrated that these FAs have the most prominent role in causing the consequences of HTG during AP. FAs inhibit mitochondrial complexes in pancreatic acinar cells, induce pathological elevation of intracellular Ca2+ concentration, cytokine release and tissue injury, and reduce the function of pancreatic ducts. Furthermore, high FA concentrations can induce respiratory, kidney, and cardiovascular failure in AP. All these effects may contribute to the observed increased AP severity and frequent organ failure in patients. Importantly, experimental results suggest that the reduction of FA production by lipase inhibitors can open up new therapeutic options of AP. Overall, investigating the pathophysiology of HTG-induced AP or AP in the presence of HTG and determining possible treatments are needed.

Predictive Value of Early Postoperative Course of Serum Cortisol After Transsphenoidal Surgery for Cushing's Disease.

OBJECTIVE: To identify early available predictors for the long-term outcome of patients after transsphenoidal surgery (TSS) in the management of Cushing's disease. METHODS: This single-center, retrospective study included 93 consecutive patients with Cushing's disease (follow-up 12-129 months, mean 48, median 38) who underwent TSS (21 had previous operations elsewhere). Six cases had early re-operation, and the resulting data were evaluated instead of the respective first operation. During the postoperative course, serum cortisol levels were assessed every four hours at least until the next morning. An association of parameters with long-term outcomes was tested using binary logistic regression. Receiver operating characteristic curves were used to determine sensitivity, specificity, positive predictive value, and negative predictive value of different cut-off values of serum cortisol in the postoperative course in the event of recurrence after remission. RESULTS: Eighty out of 93 patients (86%) showed postoperative remission (after primary treatment, 60 out of 72 patients, 90.3%). Of these, 8 patients (10%) developed recurrence of hypercortisolism. Compared to patients with persisting long-term remission, those with recurrence differed in cortisol levels starting from 4 pm on the day of surgery plus an event of increasing cortisol during the early postoperative course ("peak"). Binary logistic regression showed the association between a peak of serum cortisol in the early postoperative course with an increased probability of recurrence. CONCLUSIONS: Patients with a peak of serum cortisol in the early postoperative course show an increased recurrence rate. A cut-off value of serum cortisol for clear identification of patients with later recurrence could not be determined.

Successful treatment of severe hypertriglyceridemia with a formula diet rich in omega-3 fatty acids and medium-chain triglycerides.

BACKGROUND: Patients with highly increased plasma triglyceride levels are at risk of developing serious complications such as pancreatitis, coronary heart disease and stroke. Therefore it is important to rapidly decrease plasma triglyceride levels. A sufficient control of triglyceride levels with drugs like fibrates, statins or nicotinic acid can usually only be attained after a couple of weeks. Plasma exchange appears to be a fast but expensive method to reduce triglyceride levels. In this study we describe the use of a new omega-3 fatty acid and medium-chain triglyceride-rich formula diet as a therapeutic concept to reduce plasma triglyceride levels fast and effectively. METHODS: Thirty-two patients with severe hypertriglyceridemia were treated with the especially composed formula diet for a period of 7 days. RESULTS: Within this period of time, plasma triglycerides decreased from 1,601 (402-4,555) to 554 (142-2,382) mg/dl (p < 0.05). Total cholesterol levels were reduced from 417 (211-841) to 287 (165-457) mg/dl (p < 0.001). Fasting glucose and uric acid levels also slightly decreased (-8%; -12%). The formula diet as a 1-week treatment was well tolerated and accepted by the patients. CONCLUSION: This diet was successfully used as an acute treatment in severe hypertriglyceridemia and showed effectiveness in rapidly and safely lowering plasma triglyceride levels.

Severe hypertriglyceridemia and pancreatitis: presentation and management.

PURPOSE OF REVIEW: Hypertriglyceridemia (HTG) is a well recognized cause of acute pancreatitis accounting for approximately up to 10% of all cases and even up to 50% of all cases in pregnancy. Both primary and secondary disorders of lipoprotein metabolism may be associated with hypertriglyceridemic pancreatitis (HTGP). The purpose of this review is to provide an overview of the current studies on presentation and management of HTGP. RECENT FINDINGS/CONCLUSION: Hydrolysis of triglycerides by pancreatic lipase and formation of free fatty acids that induce inflammatory changes are postulated to account for the development of HTGP, yet the exact pathophysiology remains unclear. The clinical features of patients with HTGP are generally not different from patients with acute pancreatitis of other causes, and there is some evidence that HTGP is associated with a higher severity or a higher complication rate. There is no clear evidence as to which HTG patients will develop pancreatitis. Several studies have evaluated the effect of apheresis, the benefit of insulin and/or heparin treatment and the use of different antihyperlipidemic agents in HTGP. Dietary modifications resemble the key features in the long-term management of HTG. Whether HTG may cause chronic pancreatitis in the long-term follow-up remains controversial.

Fatty acid composition of black soldier fly larvae (Hermetia illucens) - Possibilities and limitations for modification through diet.

Black soldier fly larvae (Hermetia illucens; BSFL) can convert organic wastes into a nutrient-rich biomass suitable in animal feed, which could be a way to achieve more sustainable production of food. However, little is known about how the diet fed to BSFL affects their nutritional value, especially their fatty acid composition. In this study, BSFL were fed 11 diets based on four different organic waste sources (mussels, bread, fish and food waste). Fatty acid and proximate composition (dry matter, crude fat, crude protein and ash) were analysed in the diets, in two-week-old larvae and substrate residues. Larval weight, survival and feed conversion were also recorded. The diet was found to affect all parameters investigated. Irrespective of diet, the larval fat consisted mainly of lauric acid and other saturated fatty acids and these were found to be synthesised by the larvae. However, both the fatty acid composition of the substrate, and the larval weight were found to affect the fatty acid profile of the larvae. In general, larvae with a higher weight contained a higher percentage of saturated fatty acids and a lower percentage of unsaturated fatty acids, such as eicosapentaenoic (EPA) and docosahexaenoic acid (DHA). It was concluded that the possibilities to tailor the fatty acid composition of the BSFL through the diet are limited; thus, the BSFL fat may not be suitable to replace fish oil, but has potential of inclusion in other food, feed and fuel products.

European Guideline on IgG4-related digestive disease - UEG and SGF evidence-based recommendations.

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.

Exocrine pancreatic involvement in critically ill patients.

PURPOSE OF REVIEW: To learn about the prevalence, pathophysiology, and treatment of exocrine pancreatic involvement in critically ill patients. RECENT FINDINGS: Elevations in the levels of pancreatic enzymes are observed in up to 80% of intensive care patients. Most of these patients do not develop clinically relevant pancreatitis. However, elevations in enzyme levels do represent pancreatic damage with a risk of complications. Different factors have been discussed, which may contribute to pancreatic damage in critically ill patients. These include splanchnic hypoperfusion during shock or major surgery, bacterial translocation, elevated triglyceride levels, development of biliary sluge, and biliary pancreatitis, as well as several drugs. Imaging procedures and inflammatory markers help to identify relevant disease. Several therapeutic options have been discussed recently with a focus on early enteral nutrition. SUMMARY: Pancreatic damage is frequently observed in critically ill patients. Although in most of these patients, this is without major clinical consequences, some patients develop relevant pancreatitis, which contributes to morbidity and mortality. Risk factors have been identified and therapeutic strategies have been changed.

Determinants of Exocrine Pancreatic Function as Measured by Fecal Elastase-1 Concentrations (FEC) in Patients with Diabetes mellitus.

OBJECTIVE: Recently it has been shown that there is not only endocrine insufficiency in diabetic patients, but a frequent co-morbidity of both, the endocrine and exocrine pancreas. The present study was performed to further analyse the determinants of exocrine pancreatic function in patients with diabetes mellitus. METHODS: The records of 1992 patients with diabetes mellitus who had been treated in our hospital during a 2-year period were re-evaluated. Defined parameters were documented in standardized data sheets. Records were further checked for the results of imaging procedures of the pancreas. In 307 patients FEC had been performed and documented. Only these patients were included in further evaluation. RESULTS: FEC was inversely correlated with diabetes duration and HbA1c-levels but not with age. C-peptide levels correlated positively with FEC. BMI and FEC were also significantly correlated. There was no correlation between diabetes therapy and exocrine pancreatic function as there was no correlation with any concomitant medication. The presence of diabetes-associated antibodies was not related to FEC. According to the documented data 38 were classified as type-1 diabetes (12.4%), 167 as type-2 (54.4%), and 88 patients met the diagnostic criteria of type-3 (28.7%). Fourteen patients could not be classified because of lacking information (4.6%). CONCLUSIONS: Exocrine insufficiency might be explained as a complication of diabetes mellitus. However, it is more likely that type-3 diabetes is much more frequent than previously believed. Consequently the evaluation of exocrine function and morphology should be included into the clinical workup of any diabetic patient at least at the time of manifestation.

Effect of liquid pancreatic enzymes on the assimilation of fat in different liquid formula diets.

BACKGROUND: In some diseases, patients require high-calorie tube feeding with standard enteral formulas usually administered via temporal feeding tubes. One frequent pathophysiological condition in a relevant number of these patients is exocrine pancreatic insufficiency. Patients unable to swallow capsules might benefit from a liquid pancreatic enzyme (LPE) preparation. METHODS: LPEs were prepared and mixed with different commercially available formula diets produced for enteral feeding. Lipolysis was then measured by fatty acid titration. RESULTS: Complete lipolysis by liquid enzyme preparations was observed in diverse formula diets. Fat assimilation was even complete when LPE had been prepared 3.5 hours before the experiments, showing that the enzymes had been stable up to that time. CONCLUSIONS: The use of LPEs seems to be a good therapeutic option in patients with exocrine pancreatic insufficiency and the need for permanent high-calorie enteral feeding. Pharmaceutical companies should therefore be further encouraged to develop and distribute liquid enzyme preparations.

Successful long-term treatment of severe hypertriglyceridemia by feedback control with lipid self-monitoring.

BACKGROUND/AIMS: Successful treatment of severe hypertriglyceridemia is difficult. Besides therapy with different drugs, dietary intervention is an important approach. However, compliance with dietary recommendations is usually bad. Lipid self-monitoring in patients might improve dietary compliance and control of lipid parameters. METHODS: Thirty-two patients with severe hypertriglyceridemia (>750 mg/dl) were primarily treated with a formula diet reducing the triglyceride levels <600 mg/dl. After this acute treatment, self-monitoring of lipid parameters was performed for 48 weeks. Twenty-five patients completed the whole study. The participants measured their lipid parameters with Accutrend GCT dry chemistry strips. Dietary records were taken and measurements of body composition, BMI, triglycerides, total cholesterol and glucose were performed. RESULTS: Triglycerides remained stable in patients with levels <300 mg/dl at the beginning of the protocol. There was a significant decline in triglycerides in those who started with levels >300 mg/dl. No severe hypertriglyceridemia (>750 mg/dl) could be observed. The energy intake decreased in all patients due to a reduction in total fat and carbohydrate consumption. The relation between carbohydrates and protein remained unchanged. Self-measurement was well tolerated and an improvement in controlling the diet was reported. CONCLUSIONS: Self-control of lipid parameters can improve the dietary compliance of patients with hypertriglyceridemia and is well tolerated.

Distinct autoantibodies against exocrine pancreatic antigens in European patients with type 1 diabetes mellitus and non-alcoholic chronic pancreatitis.

CONTEXT: Histopathological analysis has demonstrated lymphocytic infiltration in both the endocrine and the exocrine pancreas in some patients with type 1 diabetes and non-alcoholic chronic pancreatitis, suggesting an immune-mediated mechanism which affects both diabetes mellitus and chronic pancreatitis. OBJECTIVE: The examination of exocrine pancreatic humoral markers in Caucasian patients with respect to the interactions between exocrine and endocrine pancreatic diseases. PATIENTS: One hundred and thirty-six European Caucasian subjects subdivided into three groups: type 1 diabetes (n=48); non-alcoholic chronic pancreatitis (n=48); controls (n=40). MAIN OUTCOME MEASURE: Autoantibodies against carbonic anhydrase II (CAIIAb) and lactoferrin (LACAb) (both of which are exocrine pancreatic antigens) were analyzed by enzyme-linked immunosorbent assay. RESULTS: No positivity for CAIIAb and LACAb were found in the controls. Patients with type 1 diabetes had a significantly higher prevalence of CAIIAb (25.0%) than the controls while the prevalence of LACAb (8.3%) was not significantly higher than the controls. The prevalence of CAIIAb (12.5%) and LACAb (20.8%) in the patients with non-alcoholic chronic pancreatitis was significantly higher than that in the controls. A significantly higher prevalence of CAIIAb and/or LACAb was found in patients with type 1 diabetes (29.2%) and non-alcoholic chronic pancreatitis (22.9%) compared to that in the controls (0%). There was a significant association between CAIIAb and LACAb titers both in patients with type 1 diabetes (P=0.042) and in patients with non-alcoholic chronic pancreatitis (P<0.001). CONCLUSION: We have clearly demonstrated that some European Caucasian patients with type 1 diabetes and non-alcoholic chronic pancreatitis have autoantibodies against the exocrine pancreatic antigens CAIIAb and LACAb.

Fecal pyruvate kinase-M2 (tumor M2-PK) measurement: a new screening concept for colorectal cancer.

BACKGROUND: Colorectal cancer (CRC) is a disease with major impact on public health and public health costs. Colonoscopy is purportedly the best screening tool for CRC. However, the acceptance by the general population is very poor. Therefore evaluation of additional screening tools is of great interest. PATIENTS AND METHODS: The use of M2-PK measurement in the feces has been reported in 6 studies to date. The data of these studies were analysed and critically reviewed. Additionally, 1,906 persons undergoing routine health care check-up provided stool samples for M2-PK measurement. RESULTS: The overall sensitivity of M2-PK is 77.9% for CRC. Specificity ranges from 74.3 to 83.3%. Of the 1,906 screened persons, 90.4% had results within the normal range, while 9.6% had elevated results. CONCLUSION: Measurement of tumor M2-PK in feces seems to be the most promising tool for CRC screening at the present time. In combination with colonoscopy, this test should hence be recommended for CRC screening programs.

Endoscopic sphincterotomy in patients with stenosis of ampulla of Vater: three-year follow-up of exocrine pancreatic function and clinical symptoms.

AIM: To investigate retrospectively the long-term effect of endoscopic sphincterotomy (ES) including exocrine pancreatic function in patients with stenosis of ampulla of Vater. METHODS: After diagnostic endoscopic retrograde cholangiopancreatography (ERCP) and ES because of stenosis of the ampulla of Vater (SOD Type I), follow-up examinations were performed in 60 patients (mean follow-up time 37.7 mo). Patients were asked about clinical signs and symptoms at present and before intervention using a standard questionnaire. Before and after ES exocrine pancreatic function was assessed by determination of immunoreactive fecal elastase 1. Serum enzymes indicating cholestasis as well as serum lipase and amylase were measured. RESULTS: Eighty percent of patients reported an improvement in their general condition after ES. The fecal elastase 1 concentrations (FEC) in all patients increased significantly after ES. This effect was even more marked in patients with pathologically low concentrations (< 200 microg/g) of fecal elastase prior to ES. The levels of serum lipase and amylase as well as serum alcaline phosphatase (AP) and gamma-glutamyltranspeptidase (GGT) decreased significantly after ES. CONCLUSION: The results of this study demonstrate that patients with stenosis of the ampulla of Vater can be successfully treated with endoscopic sphincterotomy. The positive effect is not only indicated by sustained improvement of clinical symptoms and cholestasis but also by improvement of exocrine pancreatic function.

Cannabinoid hyperemesis and the cyclic vomiting syndrome in adults: recognition, diagnosis, acute and long-term treatment.

The cannabinoid hyperemesis syndrome (CHS) and the cyclic vomiting syndrome in adults (CVS) are both characterized by recurrent episodes of heavy nausea, vomiting and frequently abdominal pain. Both syndromes are barely known among physicians. Literature is inconsistent concerning clinical features which enable differentiation between CVS and CHS. We performed a literature review using the LIVIVO search portal for life sciences to develop a pragmatic approach towards these two syndromes. Our findings indicate that complete and persistent resolution of all symptoms of the disease following cannabis cessation is the only reliable criterion applicable to distinguish CHS from CVS. Psychiatric comorbidities (e.g. panic attacks, depression), history of migraine attacks and rapid gastric emptying may serve as supportive criteria for the diagnosis of CVS. Compulsive bathing behaviour, a clinical observation previously attributed only to CHS patients is equally present in CVS patients. Long-term follow-up is essential in order to clearly separate CHS from CVS. However, long-term follow-up of CVS and CHS cases is seldom. We provide a standard operating procedure applicable to a broad spectrum of health care facilities which addresses the major issues of CVS and CHS: awareness, diagnosis, treatment, and follow-up.

United European Gastroenterology evidence-based guidelines for the diagnosis and therapy of chronic pancreatitis (HaPanEU).

BACKGROUND: There have been substantial improvements in the management of chronic pancreatitis, leading to the publication of several national guidelines during recent years. In collaboration with United European Gastroenterology, the working group on 'Harmonizing diagnosis and treatment of chronic pancreatitis across Europe' (HaPanEU) developed these European guidelines using an evidence-based approach. METHODS: Twelve multidisciplinary review groups performed systematic literature reviews to answer 101 predefined clinical questions. Recommendations were graded using the Grading of Recommendations Assessment, Development and Evaluation system and the answers were assessed by the entire group in a Delphi process online. The review groups presented their recommendations during the 2015 annual meeting of United European Gastroenterology. At this one-day, interactive conference, relevant remarks were voiced and overall agreement on each recommendation was quantified using plenary voting (Test and Evaluation Directorate). After a final round of adjustments based on these comments, a draft version was sent out to external reviewers. RESULTS: The 101 recommendations covered 12 topics related to the clinical management of chronic pancreatitis: aetiology (working party (WP)1), diagnosis of chronic pancreatitis with imaging (WP2 and WP3), diagnosis of pancreatic exocrine insufficiency (WP4), surgery in chronic pancreatitis (WP5), medical therapy (WP6), endoscopic therapy (WP7), treatment of pancreatic pseudocysts (WP8), pancreatic pain (WP9), nutrition and malnutrition (WP10), diabetes mellitus (WP11) and the natural course of the disease and quality of life (WP12). Using the Grading of Recommendations Assessment, Development and Evaluation system, 70 of the 101 (70%) recommendations were rated as 'strong' and plenary voting revealed 'strong agreement' for 99 (98%) recommendations. CONCLUSIONS: The 2016 HaPanEU/United European Gastroenterology guidelines provide evidence-based recommendations concerning key aspects of the medical and surgical management of chronic pancreatitis based on current available evidence. These recommendations should serve as a reference standard for existing management of the disease and as a guide for future clinical research.

The sword of Damocles for the splenectomised: death by OPSI.

The overwhelming post splenectomy infection (OPSI) in splenectomised patients is a rare but severe infection mostly caused by encapsulated bacteria. We analyse the case of a 65-year-old female patient who was presented with clinical and laboratory findings indicating gastroenteritis. Two years years before admission, the patient underwent a splenectomy for a two stage splenic rupture following resuscitation for pulmonary embolism. Immunisation of the patient was complete and timely. As a result of the unspecific clinical presentation, there was a delay in administration of antibiotics. However, administration of antibiotics induced a fulminant shock. The patient died 4 hours after attending the hospital due to a pneumococcal sepsis. The discussion highlights epidemiological and pathophysiological aspects and potential prevention strategies in the international context. Vaccination failed in our patient as the isolated pneumococcal strain (serogroup: 12F) is usually covered by the 23-valent pneumococcal polysaccharide vaccination (Pneumovax(®)). The case reported here indicates that there may be a potential benefit of prophylactic antibiotic treatment within the first 3 years after splenectomy for patients above the age of 65 years. Awareness of OPSI (prevention strategies, symptoms and treatment) among patients and their treating physicians is crucial for the improvement of prognosis. We partly address these issues in a standard operating procedure for the assessment of splenectomised patients in our departments of emergency medicine.

Current knowledge of hypertriglyceridemic pancreatitis.

Severe hypertriglyceridemia (HTG) is a well established and the most common cause of acute pancreatitis (AP) after alcohol and gall stone disease. It is alleged to account for up to 10% of all pancreatitis episodes. Studies suggest that in patients with triglyceride (TG) levels>1000 mg/dL (>11.3 mmol/L), hypertriglyceridemia-induced acute pancreatitis (HTGP-AP) occurs in approximately 15-20% of all subjects referred to Lipid Clinics. Until now, there is no clear evidence which patients with severe HTG will develop pancreatitis and which will not. Underlying pathophysiological concepts include hydrolysis of TG by pancreatic lipase and excessive formation of free fatty acids with inflammatory changes and capillary injury. Additionally hyperviscosity and ischemia may play a decisive role. The clinical features of HTG-AP patients are supposed to be no different from patients with AP of other etiologies. Yet, there are well-conducted studies suggesting that HTG-AP is associated with a higher severity and complication rate. Therapeutic measurements in HTG-AP include dietary modifications, different antihyperlipidemic agents, insulin and/or heparin treatment. The beneficial use of plasmapheresis is repeatedly reported and suggested in many studies. Yet, due to the lack of randomized and controlled trials, it is currently unknown if plasmapheresis may improve morbidity and mortality in the clinical setting of HTG-AP. Since there are no commonly accepted clinical guidelines in the management of HTG-AP, there is a definite need for an international, multicenter approach to this important subject.
