    MRCP has been recognized as a safe and noninvasive diagnostic method. In the present study we evaluated the usefulness of MRCP in diagnosis of chronic and acute pancreatitis. Two-dimensional fast asymmetric spin-echo (FASE) MRCP was performed in 40 patients with chronic pancreatitis and 13 with acute pancreatitis. In 29 patients (72.5%) with chronic pancreatitis and 9 (66.7%) with acute pancreatitis, main pancreatic duct (MPD) was visualized entirely. MRCP could demonstrate the characteristic findings of chronic pancreatitis such as dilatation and irregularity of MPD in most cases. In acute pancreatitis, MRCP indicated that MPD was normal in diameter, but irregular in configuration compared with that of the control group. MRCP may facilitate the diagnosis of chronic and acute pancreatitis.

    2017-01-01

    The treatment of painful chronic pancreatitis remains controversial. The available evidence from two randomized controlled trials favor surgical intervention, whereas an endotherapy-first approach is widely practiced. Chronic pancreatitis is complex disease with different genetic and environmental factors, different pain mechanisms and different treatment modalities including medical, endoscopic, and surgical. The widely practiced step-up approach remains unproven. In designing future clinical trials there are some important pre-requisites including a more comprehensive pain assessment tool, the optimization of conservative medical treatment and interventional techniques. Consideration should be given to the need of a control arm and the optimal timing of intervention. Pending better designed studies, the practical way forward is to identify subgroups of patients who clearly warrant endotherapy or surgery first, and to design the future clinical trials for the remainder.

    Objective Published evidence indicates that surgical drainage of the pancreatic duct was more effective than endoscopic drainage for patients with chronic pancreatitis. This analysis assessed the cost-effectiveness of surgical versus endoscopic drainage in obstructive chronic pancreatitis. Design This trial-based cost-utility analysis (ISRCTN04572410) was conducted from a UK National Health Service (NHS) perspective and during a 79-month time horizon. During the trial the details of the diagnostic and therapeutic procedures, and pancreatic insufficiency were collected. The resource use was varied in the sensitivity analysis based on a review of the literature. The health outcome was the Quality-Adjusted Life Year (QALY), generated using EQ-5D data collected during the trial. There were no pancreas-related deaths in the trial. All-cause mortality from the trial was incorporated into the QALY estimates in the sensitivity analysis. Setting Hospital. Participants Patients with obstructive chronic pancreatitis. Primary and secondary outcome measures Costs, QALYs and cost-effectiveness. Results The result of the base-case analysis was that surgical drainage dominated endoscopic drainage, being both more effective and less costly. The sensitivity analysis varied mortality and resource use and showed that the surgical option remained dominant in all scenarios. The probability of cost-effectiveness for surgical drainage was 100% for the base case and 82% in the assessed most conservative case scenario. Conclusions In obstructive chronic pancreatitis, surgical drainage is highly cost-effective compared with endoscopic drainage from a UK NHS perspective. PMID:24065699

    Pancreatic cancer is the fourth leading cause of cancer deaths in the USA in both sexes. Early diagnosis is difficult and the overall mortality rate is high. Individuals at high risk for pancreatic cancer include smokers, and persons with all forms of chronic alcoholic, metabolic, tropical or hereditary pancreatitis. The duration of exposure to inflammation seems to be the major factor involved in the transition from benign to malignant condition. Smoking, which appears to further accelerate the carcinogenic transformation, remains the strongest risk factor amenable to preventive intervention.

    The effect of combined use of pentoxifylline and solcoseryl was studied in 35 patients with chronic pancreatitis. General clinical findings were studied in parallel with the time course of pancreatic exocrine (trypsin) and endocrine (insulin, C-peptide) function. The blood level of gastrin and changes in intestinal function using 131I-lipids were also studied. The incorporation of both drugs in multimodality therapy made a positive therapeutic effect, resulting in a decrease in the pain syndrome and dyspeptic symptoms. At the same time some favorable shifts in pancreatic and GI tract function were noted. Possible mechanisms of a positive therapeutic effect were discussed. A conclusion was made that the incorporation of pentoxifylline and solcoseryl in multimodality therapy of chronic pancreatitis was clinically justified and determined pathogenetically.

    2015-01-01

    Full Text Available Introduction. Pancreatic actinomycosis is a chronic infection of the pancreas caused by the suppurative Gram-positive bacterium Actinomyces. It has mostly been described in patients following repeated main pancreatic duct stenting in the context of chronic pancreatitis or following pancreatic surgery. This type of pancreatitis is often erroneously interpreted as pancreatic malignancy due to the specific invasive characteristics of Actinomyces. Case. A 64-year-old male with a history of chronic pancreatitis and repeated main pancreatic duct stenting presented with weight loss, fever, night sweats, and abdominal pain. CT imaging revealed a mass in the pancreatic tail, invading the surrounding tissue and resulting in splenic vein thrombosis. Resectable pancreatic cancer was suspected, and pancreatic tail resection was performed. Postoperative findings revealed pancreatic actinomycosis instead of neoplasia. Conclusion. Pancreatic actinomycosis is a rare type of infectious pancreatitis that should be included in the differential diagnosis when a pancreatic mass is discovered in a patient with chronic pancreatitis and prior main pancreatic duct stenting. Our case emphasizes the importance of pursuing a histomorphological confirmation.

  14. Antioxidants and chronic pancreatitis: theory of oxidative stress and trials of antioxidant therapy.

    Science.gov (United States)

    2012-04-01

    Chronic pancreatitis (CP) is an inflammatory disease characterized by the progressive destruction of pancreatic tissue and resulting in pancreatic exocrine and endocrine insufficiency. Increased oxidative stress has been implicated as a potential mechanism in its etiology and pathology. A number of studies have demonstrated that CP patients have a compromised antioxidant status, which may be a contributing factor to the enhanced oxidative state associated with the disease. Nutrition is an essential consideration in the treatment of CP, especially since diet is a source of several antioxidants and cofactors required for the production of cellular antioxidant enzymes. Many CP patients have an inadequate intake of macro and micronutrients because of abdominal pain and discomfort, which often increase postprandially and discourage eating. Exocrine insufficiency leads to further complications by preventing adequate digestion and absorption of ingested food, thus causing even greater deficiencies and impairment of antioxidant status. The aims of this article are to review the oxidative stress model of CP and to examine the evidence for nutrition, and, particularly, antioxidants, in the treatment of CP.

    Chronic pancreatitis used to be considered uncommon in dogs, but recent pathological and clinical studies have confirmed that it is in fact a common and clinically significant disease. Clinical signs can vary from low-grade recurrent gastrointestinal signs to acute exacerbations that are indistinguishable from classical acute pancreatitis. Chronic pancreatitis is a significant cause of chronic pain in dogs, which must not be underestimated. It also results in progressive impairment of endocrine and exocrine function and the eventual development of diabetes mellitus or exocrine pancreatic insufficiency or both in some affected dogs at end stage. The etiology is unknown in most cases. Chronic pancreatitis shows an increased prevalence in certain breeds, and recent work in English Cocker Spaniels suggests it is part of a polysystemic immune-mediated disease in this breed. The histological and clinical appearance is different in different breeds, suggesting that etiologies may also be different. Diagnosis is challenging because the sensitivities of the available noninvasive tests are relatively low. However, with an increased index of suspicion, clinicians will recognize more cases that will allow them to institute supportive treatment to improve the quality of life of the patient.

    BACKGROUND:Treatment of chronic pancreatitis (CP) is a challenging condition for surgeons. During the last decades, increasing knowledge about pathophysiology of CP, improved results of major pancreatic resections, and integration of sophisticated diagnostic methods in clinical practice have resulted in signiifcant changes in surgery for CP. DATA SOURCES:To detail the indications for CP surgery, the surgical procedures, and outcome, a Pubmed database search was performed. The abstracts of searched articles about surgical management of CP were reviewed. The articles could be identiifed and further scrutinized. Further references were extracted by cross-referencing. RESULTS: Main indications of CP for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The goal of surgical treatment is to improve the quality of life of patients. The surgical approach to CP should be individualized according to pancreatic anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. The approach usually involves pancreatic duct drainage and resection including longitudinal pancreatojejunostomy, pancreatoduodenectomy (Whipple's procedure), pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Non-pancreatic and endoscopic management of pain has also been advocated. CONCLUSIONS:Surgical procedures provide long-term pain relief, a good postoperative quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low early and late mortality and morbidity. In addition to available results from randomized controlled trials, new studies are needed to determine which procedure is the most effective for the management of patients with CP.

    Full Text Available Chronic pancreatitis is a disease often characterized by recurrent episodes of abdominal pain accompanied by progressive pancreatic exocrine and endocrine insufficiency [1] and it sometimes requires multiple hospitalizations. Obstructive jaundice, duodenal stenosis, left-sided portal hypertension, pseudocyst and mass formation, and pancreatic carcinoma may occur as complications of chronic pancreatitis. The disease is frequently the result of chronic alcohol abuse, even if other factors such as genetic alterations, autoimmune disorders, and obstructive disease of the biliary tract and the pancreas may cause the disease [2]. Medical therapy is the treatment of choice for most patients and it is based on substitutive therapy for either exocrine or endocrine insufficiency and on analgesics for pain control. In the presence of intractable pain, surgical management is the main option [3] even if, in recent years, other therapeutic options such as endoscopic therapy [4], thoracoscopic splanchnicectomy [5], and extracorporeal shockwave lithotripsy have been applied in clinical practice [6]. From a pathological point of view, chronic pancreatitis is characterized by irregular sclerosis with destruction and loss of the exocrine parenchyma, and complete replacement of acinar, ductal and endocrine tissue by fibrotic tissue. It has recently been reported that acute alcoholic pancreatitis develops in a pancreas already affected by chronic pancreatitis [7]. In 1982, Watari et al. [8] reported the presence of vitamin A-containing cells in the vitamin A-fed rat pancreas. These were later described and characterized as stellate cells in the rat and the human pancreas [9, 10]. Pancreatic stellate cells are morphologically similar to hepatic stellate cells. They bear long cytoplasmic processes and are situated close to the pancreatic acini. In the quiescent state, these cells contain lipid droplets, store vitamin A and express markers such as desmin, glial

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Treatment of chronic pancreatitis has been exclusively surgical for a long time. Recently, endoscopic therapy has become widely used as a primary therapeutic option.Initially performed for drainage of pancreatic cysts and pseudocysts, endoscopic treatments were adapted to biliary and pancreatic ducts stenosis. Pancreatic sphincterotomy which allows access to pancreatic ducts was firstly reported. Secondly, endoscopic methods of stenting, dilatation, and stones extraction of the bile ducts were applied to pancreatic ducts. Nevertheless,new improvements were necessary: failures of pancreatic stone extraction justified the development of extra-corporeal shock wave lithotripsy; dilatation of pancreatic stenosis was improved by forage with a new device; moreover endosonography allowed guidance for celiac block, gastro-cystostomy, duodeno-cystostomy and pancreatico-gastrostomy. Although endoscopic treatments are more and more frequently accepted,indications are still debated.

    Drug absorption in patients with chronic pancreatitis might be affected by the pathophysiology of the disease. The exocrine pancreatic insufficiency is associated with changes in gastrointestinal intraluminal pH, motility disorder, bacterial overgrowth and changed pancreatic gland secretion....... Together these factors can result in malabsorption and may also affect the efficacy of pharmacological intervention. The lifestyle of chronic pancreatitis patients may also contribute to gastrointestinal changes. Many patients limit their food intake because of the pain caused by eating and in some cases...... food intake is more or less substituted with alcohol, tobacco and coffee. Alcohol and drug interaction are known to influence the pharmacokinetics by altering either drug absorption or by affecting liver metabolism.

    Full Text Available Any link between pancreatic carcinoma and chronic pancreatitis could reflect the malignant potential of a chronic inflammatory process. Four patients with ductal adenocarcinomas had a long history of pancreatic pain (median duration 5 years and showed clearcut evidence of chronic pancreatitis “downstream” of the tumour. Four were alcoholics and two heavy smokers. These four cases arose within a surgical series of approximately 250 patients with chronic pancreatitis, giving an incidence of 1.6 per cent. The incidence and anatomical distribution of carcinoma and chronic pancreatitis could possibly be consistent with a casual relationship.

    Full Text Available Chronic pancreatitis is characterised by progressive and irreversible damage of the pancreatic parenchyma and ductal system, which leads to chronic pain, loss of endocrine and exocrine functions. Clinically, pancreatic exocrine insufficiency becomes apparent only after 90% of the parenchima has been lost. Despite the simple definition, diagnosing chronic pancreatitis remains a challenge, especially for early stage disease. Because pancreatic function tests can be normal until late stages and have significant limitations, there is an incresing interest in the role of imaging techniques for the diagnosis of chronic pancreatitis. In this article we review the utility and accuracy of different imaging methods in the diagnosis of chronic pancreatitis, focusing on the role of advanced imaging (magnetic resonance imaging, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.

    Pancreatitis may be acute or chronic. Although both can be caused by similar aetiologies, they tend to follow distinct natural histories. Around 80% of acute pancreatitis (AP) diagnoses occur secondary to gallstone disease and alcohol misuse. AP is commonly associated with sudden onset of upper abdominal pain radiating to the back that is usually severe enough to warrant the patient seeking urgent medical attention. Onset of pain may be related to a recent alcohol binge or rich, fatty meal. The patient may appear unwell, be tachycardic and have exquisite tenderness in the upper abdomen. Overall, 10-25% of AP episodes are classified as severe, leading to an associated mortality rate of 7.5%. Disease severity is best predicted from a number of clinical scoring systems which can be applied at diagnosis in association with repeated clinical assessment, measurement of acute inflammatory markers, and CT. All patients with suspected AP should be referred urgently. Chronic pancreatitis (CP) follows continued, repetitive or sustained injury to the pancreas and 70% of diagnoses occur secondary to alcohol abuse. The characteristic presenting feature of CP is insidious progression of chronic, severe, upper abdominal pain, radiating to the back, caused by a combination of progressive pancreatic destruction, inflammation and duct obstruction. Signs and symptoms include weight loss and steatorrhoea and later on diabetes. CP patients may also present with recurrent episodes mimicking AP, both symptomatically and metabolically. Diagnosis of CP should be based on symptom profile, imaging and assessment of exocrine and endocrine pancreatic function. CT should be the first-line imaging investigation.

    2013-06-01

    Animal models of acute and chronic pancreatitis have been created to examine mechanisms of pathogenesis, test therapeutic interventions, and study the influence of inflammation on the development of pancreatic cancer. In vitro models can be used to study early stage, short-term processes that involve acinar cell responses. Rodent models reproducibly develop mild or severe disease. One of the most commonly used pancreatitis models is created by administration of supraphysiologic concentrations of caerulein, an ortholog of cholecystokinin. Induction of chronic pancreatitis with factors thought to have a role in human disease, such as combinations of lipopolysaccharide and chronic ethanol feeding, might be relevant to human disease. Models of autoimmune chronic pancreatitis have also been developed. Most models, particularly of chronic pancreatitis, require further characterization to determine which features of human disease they include.

    Pancreatitis is becoming increasingly prevalent in children, posing new challenges to pediatric health care providers. Although some general adult treatment paradigms are applicable in the pediatric population, diagnostic workup and surgical management of acute and chronic pancreatitis have to be tailored to anatomic and pathophysiological entities peculiar to children. Nonbiliary causes of acute pancreatitis in children are generally managed nonoperatively with hydration, close biochemical and clinical observation, and early initiation of enteral feeds. Surgical intervention including cholecystectomy or endoscopic retrograde cholangiopancreatography is often required in acute biliary pancreatitis, whereas infected pancreatic necrosis remains a rare absolute indication for pancreatic debridement and drainage via open, laparoscopic, or interventional radiologic procedure. Chronic pancreatitis is characterized by painful irreversible changes of the parenchyma and ducts, which may result in or be caused by inadequate ductal drainage. A variety of surgical procedures providing drainage, denervation, resection, or a combination thereof are well established to relieve pain and preserve pancreatic function.

    Abdominal pain is a major clinical problem in patients with chronic pancreatitis.The cause of pain is usually multifactorial with a complex interplay of factors contributing to a varying degree to the pain in an individual patient and,therefore,a rigid standardized approach for pain control tends to lead to suboptimal results.Pain management usually proceeds in a stepwise approach beginning with general lifestyle recommendations,low fat diet,alcohol and smoking cessation are encouraged.Analgesics alone are needed in almost all patients.Maneuvers aimed at suppression of pancreatic secretion are routinely tried.Patients with ongoing symptoms may be candidates for more invasive options such as endoscopic therapy,and resective or drainage surgery.The role of pain modifying agents (antidepressants,gabapentin,peregabalin),celiac plexus block,antioxidants,octreotide and total pancreatectomy with islet cell auto transplantation remains to be determined.

    Modern imaging techniques have revolutionized the diagnostic evaluation of pancreatitis, primarily demonstrating its complications. Computerized tomography (CT) is a more sensitive method than ultrasonography and pancreatic ductography. A chart review revealed 214 patients at our hospital with a discharge diagnosis of pancreatitis. Sixty patients had CT for evaluation of possible complications. Only five scans were normal. Of 37 cases of acute pancreatitis, 92% demonstrated localized or diffuse enlargement, and 65% showed loss of pancreatic outline. Other frequent findings included thickening of perirenal fascia (49%), ileus (43%), edema of mesentery (35%), and inflammatory exudate (32%). Abscess and pseudocyst were each detected in 8% of cases. In chronic pancreatitis 65% of patients showed localized or diffuse pancreatic enlargement. Atrophy of the gland (30%), calcification (30%), pseudocyst (26%), and dilated pancreatic ducts (17%) were also seen. CT is effective in evaluating pancreatitis and its complications. 14 references, 5 figures, 2 tables.

    慢性胰腺炎的临床表现包括疼痛、脂肪泻和糖尿病.在西方国家,慢性胰腺炎最常见的病因是酗酒.70%以上的病人在就诊时有疼痛的临床表现,而且,这些患者中又有75%以上会在几年之后出现疼痛减轻或完全消失.对于所有的慢性胰腺炎的病人来说,均应排除非胰源性疼痛和胆道梗阻、胰腺假性囊肿等胰腺局部并发症.应建议所有慢性胰腺炎病人戒烟、戒酒.阿片类镇痛剂仅应用于治疗疼痛严重的病人.尽管有报道认为胰酶替代治疗有助于止痛,但是,对于已经确诊的慢性胰腺炎病人来说,该疗法无效.激素类药物进行腹腔神经丛阻滞术可能有助于病人度过剧烈疼痛期.顽固性疼痛是进行胰液引流或胰腺切除的适应证.建议应用适量胰酶替代联合(或不联合)制酸剂治疗营养不良.慢性胰腺炎导致的糖尿病与原发性糖尿病的治疗原则相似.%The clinical presentation of chronic pancreatitis includes pain, steatorrhea and diabetes. The most common etiology in the western world is excess alcohol use. Pain is present in >70% patients at presentation and decreases in intensity or resolves over several years in up to 75% of patients. Non-pancreatic causes of pain and local complications, chiefly pseudocysts and biliary obstruction should be excluded in all patients. All patients should be advised to abstain from alcohol and smoking and opiates should be used only to control severe exacerbations of pain. Although pancreatic enzyme replacement is reported to be useful in the management of pancreatic pain, it is of little or no benefit in patients with established chronic pancreatitis. Celiac plexus block using steroids may be helpful to tide patients over an episode of severe pain. Intractable pain is an indication for surgery that includes pancreatic drainage procedure or pancreatic resection. For control of malabsorption, adequate pancreatic enzyme replacement with or

    Pancreatitis can manifest as a one-time episode, recurring attacks, or chronic pain. It is caused by numerous factors ranging from alcohol consumption to gallstones to subtle obstructive causes and occult autoimmune disorders. As a result, determining the etiology and effectively treating the causes and consequences of pancreatitis can be challenging. This article reviews the diagnosis and management of acute, acute recurrent, and chronic pancreatitis, focusing on more challenging scenarios.

    Full Text Available Chronic pancreatitis (CP is a progressive inflammatory disease in which the pancreatic secretory parenchyma is destroyed and replaced by fibrosis. The presence of intraductal pancreatic stone(s is important for the diagnosis of CP; however, the precise molecular mechanisms of pancreatic stone formation in CP were left largely unknown. CFTR is a chloride channel expressed in the apical plasma membrane of pancreatic duct cells and plays a central role in HCO3- secretion. In previous studies, we have found that CFTR is largely mislocalized to the cytoplasm of pancreatic duct cells in all forms of CP and corticosteroids normalizes the localization of CFTR to the proper apical membrane at least in autoimmune pancreatitis. From these observations, we could conclude that the mislocalization of CFTR is a cause of protein plug formation in CP, subsequently resulting in pancreatic stone formation.Considering our observation that the mislocalization of CFTR also occurs in alcoholic or idiopathic CP, it is very likely that these pathological conditions can also be treated by corticosteroids, thereby preventing pancreatic stone formation in these patients. Further studies are definitely required to clarify these fundamental issues.

    AIM: To investigate the markers of pancreatic diseases and provide basic data and experimental methods for the diagnosis of pancreatic diseases. METHODS: There were 15 patients in the present study, among whom 10 had pancreatic cancer and 5, chronic pancreatitis. In all patients, pancreatic cancer or chronic pancreatitis was located on the head of the p-a-ncreas. Pathology data of all pa tients was confirmed by biopsy and surgery. Among the 10 patients with pancreatic cancer, 3 people had a medical history of longterm alcohol consumption. Of 5 patients with chronic pancreatitis, 4 men suffered from alcoholic chronic pancreatitis. Pancreatic juice samples were obtained from patients by endoscopic retrograde cholangiopancreatography. Magnetic resonance spectroscopyn was performed on an 11.7-T scanner (Bruker DRX-500) using Call-Purcell-Meiboom-Gill pulse sequences. The parameters were as follows: spectral width, 15 KHz; time domain, 64 K; number of scans, 512; and acquisition time, 2.128 s. RESULTS: The main component of pancreatic juice included leucine, iso-leucine, valine, lactate, alanine, acetate, aspartate, lysine, glycine, threonine, tyrosine, histidine, tryptophan, and phenylalanine. On performing 1D 1H and 2D total correlation spectroscopy, we found a triplet peak at the chemical shift of 1.19 ppm, which only appeared in the spectra of pancreatic juice obtained from patients with alcoholic chronic pancreatitis. This triplet peak was considered the resonance of the methyl of ethoxy group, which may be associated with the metabolism of alcohol in the pancreas. CONCLUSION: The triplet peak, at the chemical shift of 1.19 ppm is likely to be the characteristic metabolite of alcoholic chronic pancreatitis.

    Full Text Available INTRODUCTION: The principal indication for surgical intervention in chronic pancreatitis is intractable pain. Depending upon the presence of dilated pancreatic ductal system, pancreatic duct drainage procedures and different kinds of pancreatic resections are applied. OBJECTIVE: The objective of the study was to show the most appropriate procedure to gain the most possible benefits in dependence of type of pathohistological process in chronic pancreatitis. METHOD: Our study included 58 patients with intractable pain caused by chronic pancreatitis of alcoholic genesis. The first group consisted of 30 patients with dilated pancreatic ductal system more than 10 mm. The second group involved 28 patients without dilated pancreatic ductal system. Pain relief, weight gain and glucose tolerance were monitored. RESULTS: All patients of Group I (30 underwent latero-lateral pancreaticojejunal - Puestow operation. 80% of patients had no pain after 6 month, 13.6% had rare pain and 2 patients, i.e. 6.4%, who continued to consume alcohol, had strong pain. Group II consisting of 28 patients was without dilated pancreatic ductal system. This group was subjected to various types of pancreatic resections. Whipple procedure (W was done in 6 patients, pylorus preserving Whipple (PPW in 7 cases, and duodenum preserving cephalic pancreatectomy (DPCP was performed in 15 patients. Generally, 89.2% of patients had no pain 6 month after the operation. An average weight gain was 1.9 kg in W group, 2.8 kg in PPW group and 4.1 kg in DPCP group. Insulin-dependent diabetes was recorded in 66.6% in W group, 57.1% in PPW group and 0% in DPCP group. CONCLUSION: According to our opinion, DPCP may be considered the procedure of choice for surgical treatment of pain in chronic pancreatitis in patients without dilatation of pancreas ductal system because of no serious postoperative metabolic consequences.

    Full Text Available Context: Groove pancreatitis is a rare form of chronic pancreatitis affecting the "groove" of the pancreas among the pancreatic head, duodenum, and common bile duct. The exact cause is unknown, although there are associations with long-term alcohol abuse, smoking, peptic ulcer disease, heterotopic pancreas, gastric resection, biliary disease, and anatomical or functional obstruction of the minor papilla. The diagnosis can be challenging. Endoscopic ultrasound (EUS and magnetic resonance cholangiopancreatography are the preferred imaging modalities. The treatment of choice is conservative although surgical intervention can sometimes be required. Case Report: A 57-year-old male with a history of human immunodeficiency virus and hepatitis B presented with 4 days of epigastric pain. Abdominal exam revealed absent bowel sounds and epigastric tenderness. He had a creatinine of 1.72 mg/dL, potassium of 2.9 mmol/L, and a normal lipase level of 86 U/L. Liver enzymes and total bilirubin were normal. Computed tomography abdomen showed high-grade obstruction of the second portion of the duodenum without any obvious mass. An esophagogastroduodenoscopy showed a mass at the duodenal bulb causing luminal narrowing, with biopsies negative for malignancy. Magnetic resonance imaging revealed a mass in the region of the pancreatic head and descending duodenum. EUS revealed a 3 cm mass in the region of pancreatic head with irregular borders and no vascular invasion. Fine needle aspiration (FNA was nondiagnostic. The patient then underwent a Whipple′s procedure. Pathology of these specimens was negative for malignancy but was consistent with para-duodenal or groove pancreatitis. Conclusion: The low incidence of groove pancreatitis is partly due to lack of familiarity with the disease. Groove pancreatitis should be considered in the differential for patients presenting with pancreatic head lesions and no cholestatic jaundice, especially when a duodenal obstruction

    BACKGROUND: Acinar cell carcinoma (ACC) is a rare malignancy of the pancreas arising from acinar cells. Unlike ductal adenocarcinoma, this tumor rarely presents with pancreatitis. METHODS: We present a case of ACC associated with chronic calcifying pancreatitis, and a review of the literature focusing on diagnosis and management. RESULTS: A 43-year-old man was proposed for Wirsungo-jejunal derivation for chronic pancreatitis. Histopathological examination of the tissue extracted revealed an ACC. Duodenopancreatectomy was performed. Six months post-operatively, the patient developed hepatic metastasis and was treated with gemcitabine as palliative chemotherapy. CONCLUSIONS: The clinical presentation of ACC of the pancreas is not speciifc and the tumor can be under-diagnosed when associated with chronic pancreatitis. Data regarding course, treatment, and prognosis of this tumor are generally lacking.

    A 39-year-old man was referred to our hospital for the investigation of abdominal fluid collection. He was pointed out to have alcoholic chronic pancreatitis. Laboratory data showed inflammation and slightly elevated serum direct bilirubin and amylase. An abdominal computed tomography demonstrated huge fluid collection, multiple pancreatic pseudocysts and pancreatic calcification. The fluid showed a high level of amylase at 4,490 IU/l. Under the diagnosis of pancreatic ascites, endoscopic pancreatic stent insertion was attempted but was unsuccessful, so surgical treatment (Frey procedure and cystojejunostomy) was performed. During the operation, a huge amount of fluid containing bile acid (amylase at 1,474 IU/l and bilirubin at 13.5 mg/dl) was found to exist in the extraperitoneal space (over the peritoneum), but no ascites was found. His postoperative course was uneventful and he shows no recurrence of the fluid. Pancreatic ascites is thought to result from the disruption of the main pancreatic duct, the rupture of a pancreatic pseudocyst, or possibly leakage from an unknown site. In our extremely rare case, the pancreatic pseudocyst penetrated into the hepatoduodenal ligament with communication to the common bile duct, and the fluid flowed into the round ligament of the liver and next into the extraperitoneal space.

    AIM: To elucidate the frequency and characteristics of pancreatic disorders in the course of chronic viral hepatitis. METHODS: We prospectively assessed the serum pancreatic enzyme levels and imaging findings in patients with chronic viral hepatitis and healthy control subjects. RESULTS: Serum amylase (t-Amy), salivary amylase (s-Amy), pancreatic amylase (p-Amy) and serum lipase levels were higher in hepatitis patients in comparison to control subjects. However, in asymptomatic viral carriers, only the serum t-Amy levels were higher than those of the controls. The levels of each enzyme rose with the progression of liver disease in patients with hepatitis B or C; whereas the levels of each enzyme within the same clinical stage of the disease did not differ between patients diagnosed with either hepatitis B or hepatitis C virus. Imaging findings demonstrated chronic pancreatitis in only 1 out of 202 patients (0.5%).CONCLUSION: Our data suggest that serum levels of pancreatic enzymes increase with the progression of liver disease in patients diagnosed with viral hepatitis. Pancreatic disease, asymptomatic in most cases, may represent an extrahepatic manifestation of chronic viral hepatitis.

    Pseudocyst is a common complication of Acute and chronic pancreatitis. However, its extension into the mediastinum is a rare entity. We present a case of 52 years male with acute on chronic pancreatitis (alcohol related) who presented with dysphagia and dyspnoea and was found to have a pancreatic pseudocyst extending upto the neck. Ultrasound fails to pick up mediastinal pseudocysts and requires additional imaging modalities - CT and MRI. Management of Mediastinal pseudocyst depends upon underlying etiology, ductal anatomy, size of the pseudocyst, and availability of expertise. Small pseudocysts in asymptomatic patients may resolve spontaneously, but requires prolonged conservative therapy with somatostatin or its analogue and Total Parenteral Nutrition. Ruptured pseudocyst in a symptomatic unstable patient requires surgical resection. Endoscopic ultrasound guided drainage (transmural or transpapillary) and Main Pancreatic Duct stenting are safe and effective treatment modality.

  19. Alcohol consumption in patients with acute or chronic pancreatitis.

    Sand, J; Lankisch, P G; Nordback, I

    2007-01-01

    Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.

    Nutritional support can have a significant beneficial impact on the course of moderate to severe acute pancreatitis. Enteral nutrition is preferred, with emphasis on establishment of jejunal access; however, parenteral nutrition can also be of value if intestinal failure is present. Early initiation of nutritional support is critical, with benefits decreasing rapidly if begun after 48 hours from admission. Severe malnutrition in chronic pancreatitis can be avoided or treated with dietary modifications or enteral nutrition.

    Full Text Available Chronic pancreatitis is a chronic inflammatory disorder of the pancreas. The etiology is multi-fold, but all lead to progressive scarring and loss of pancreatic function. Early diagnosis is difficult; and the understanding of the molecular events that underlie this progressive disease is limited. In this study, we investigated differential proteins associated with mild and severe chronic pancreatitis in comparison with normal pancreas and pancreatic cancer. Paraffin-embedded formalin-fixed tissues from five well-characterized specimens each of normal pancreas (NL, mild chronic pancreatitis (MCP, severe chronic pancreatitis (SCP and pancreatic ductal adenocarcinoma (PDAC were subjected to proteomic analysis using a "label-free" comparative approach. Our results show that the numbers of differential proteins increase substantially with the disease severity, from mild to severe chronic pancreatitis, while the number of dysregulated proteins is highest in pancreatic adenocarcinoma. Important functional groups and biological processes associated with chronic pancreatitis and cancer include acinar cell secretory proteins, pancreatic fibrosis/stellate cell activation, glycoproteins, and inflammatory proteins. Three differential proteins were selected for verification by immunohistochemistry, including collagen 14A1, lumican and versican. Further canonical pathway analysis revealed that acute phase response signal, prothrombin activation pathway, and pancreatic fibrosis/pancreatic stellate cell activation pathway were the most significant pathways involved in chronic pancreatitis, while pathways relating to metabolism were the most significant pathways in pancreatic adenocarcinoma. Our study reveals a group of differentially expressed proteins and the related pathways that may shed light on the pathogenesis of chronic pancreatitis and the common molecular events associated with chronic pancreatitis and pancreatic adenocarcinoma.

    The pathogenesis of chronic pancreatitis (CP) is poorly understood. Endoplasmic reticulum (ER) stress has now been recognized as a pathogenic event in many chronic diseases. However, ER stress has not been studied in CP, although pancreatic acinar cells seem to be especially vulnerable to ER dysfunction because of their dependence on high ER volume and functionality. Here, we aim to investigate ER stress in CP, study its pathogenesis in relation to trypsinogen activation (widely regarded as the key event of pancreatitis), and explore its mechanism, time course, and downstream consequences during pancreatic injury. CP was induced in mice by repeated episodes of acute pancreatitis (AP) based on caerulein hyperstimulation. ER stress leads to activation of unfolded protein response components that were measured in CP and AP. We show sustained up-regulation of unfolded protein response components ATF4, CHOP, GRP78, and XBP1 in CP. Overexpression of GRP78 and ATF4 in human CP confirmed the experimental findings. We used novel trypsinogen-7 knock-out mice (T(-/-)), which lack intra-acinar trypsinogen activation, to clarify the relationship of ER stress to intra-acinar trypsinogen activation in pancreatic injury. Comparable activation of ER stress was seen in wild type and T(-/-) mice. Induction of ER stress occurred through pathologic calcium signaling very early in the course of pancreatic injury. Our results establish that ER stress is chronically activated in CP and is induced early in pancreatic injury through pathologic calcium signaling independent of trypsinogen activation. ER stress may be an important pathogenic mechanism in pancreatitis that needs to be explored in future studies.

    Intense abdominal pain is a prominent feature of chronic pancreatitis and its treatment remains a major clinical challenge. Basic studies of pancreatic nerves and experimental human pain research have provided evidence that pain processing is abnormal in these patients and in many cases resembles that seen in neuropathic and chronic pain disorders. An important ultimate outcome of such aberrant pain processing is that once the disease has advanced and the pathophysiological processes are firmly established, the generation of pain can become self-perpetuating and independent of the initial peripheral nociceptive drive. Consequently, the management of pain by traditional methods based on nociceptive deafferentation (e.g., surgery and visceral nerve blockade) becomes difficult and often ineffective. This novel and improved understanding of pain aetiology requires a paradigm shift in pain management of chronic pancreatitis. Modern mechanism based pain treatments taking into account altered pain processing are likely to increasingly replace invasive therapies targeting the nociceptive source, which should be reserved for special and carefully selected cases. In this review, we offer an overview of the current available pharmacological options for pain management in chronic pancreatitis. In addition, future options for pain management are discussed with special emphasis on personalized pain medicine and multidisciplinarity.

    Full Text Available About half of all patients with chronic pancreatitis (CP develop diabetes mellitus (DM due to the loss of islet cell mass, not just beta cells as in Type 1 DM (T1DM, or due to insulin resistance, as in Type 2 DM (T2DM. Patients with DM from loss of islets due to pancreatic disease or resection are diagnosed with pancreatogenic or Type 3c DM (T3cDM. Patients with T3cDM also lose counter-regulatory hormones, such as glucagon and pancreatic polypeptide, and experience maldigestion associated with pancreatic exocrine insufficiency. Patients with T3cDM are therefore more susceptible to hypoglycemia and a mismatch (asynchrony between food ingestion and nutrient absorption. At the same time, the use of incretin therapy is likely useless, since maldigestion leads to the release of higher levels of hind gut hormones, including GLP1. Thus, T3cDM caused by CP or destruction of the islets involves a special class of potential risks and comorbidity that may be overlooked if the CP has not been diagnosed.

    Abstract Background: Chronic pancreatitis (CP) is a common and frequently occurring disease. Pancreaticoduodenectomy (PD), pylorus-preserving pancreaticoduodenectomy (PPPD), and duodenum-preserving pancreatic head resection (DPPHR) are important treatment options for patients with chronic pancreatitis. The Beger and Frey procedures are 2 main duodenum-preserving techniques in duodenum-preserving pancreatic head resection (DPPHR) strategies. We conducted this systematic review and meta-analysis to compare the clinical efficacy of DPPHR versus PD, the Beger procedure versus PD, the Frey procedure versus PD, and the Beger procedure versus the Frey procedure in the treatment of pancreatitis. The optimal surgical option for chronic pancreatitis is still under debate. The aim of this systematic review and meta-analysis was to evaluate the clinical efficacy of different surgical strategies for chronic pancreatitis. Methods: Five databases (PubMed, Medline, SinoMed, Embase, and Cochrane Library) were searched with the limitations of human subjects and randomized controlled trials (RCTs) text. Data were extracted by 2 of the coauthors independently and analyzed using the RevMan statistical software, version 5.3. Weighted mean differences (WMDs), risk ratios (RRs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool was used to assess the risk of bias. Results: Seven studies involving a total of 385 patients who underwent the surgical treatments were assessed. The methodological quality of the trials ranged from low to moderate and included PD (n = 134) and DPPHR (n = 251 [Beger procedure = 100; Frey procedure = 109; Beger or Frey procedure = 42]). There were no significant differences between DPPHR and PD in post-operation mortality (RR = 2.89, 95% CI = 0.31–26.87, P = 0.36), pain relief (RR = 1.09, 95% CI = 0.94–1.25, P = 0.26), exocrine insufficiency (follow-up time > 60 months

    Aim: To retrospectively establish the most frequently encountered diagnoses in patients with pancreatic calcifications and to investigate whether the association of certain findings could be helpful for diagnosis. Materials and methods: One hundred and three patients were included in the study. The location and distribution of calcifications; presence, nature, and enhancement pattern of pancreatic lesions; pancreatic atrophy and ductal dilatation were recorded. Differences between patients with chronic pancreatitis and patients with other entities were compared by using Fisher's exact test. Results: Patients had chronic pancreatitis (n = 70), neuroendocrine tumours (n = 14), intraductal papillary mucinous neoplasm (n = 11), pancreatic adenocarcinoma (n = 4), serous cystadenoma (n = 4). Four CT findings had a specificity of over 60% for the diagnosis of chronic pancreatitis: parenchymal calcifications, intraductal calcifications, parenchymal atrophy, and cystic lesions. When at least two of these four criteria were used in combination, 54 of 70 (77%) patients with chronic pancreatitis could be identified, but only 17 of 33 (51%) patients with other diseases. When at least three of these four criteria were present, a specificity of 79% for the diagnosis of chronic pancreatitis was achieved. Conclusion: Certain findings are noted more often in chronic pancreatitis than in other pancreatic diseases. The presence of a combination of CT findings can suggest chronic pancreatitis and be helpful in diagnosis.

    Autoimmune chronic pancreatitis (AIP) is increasingly being recognized worldwidely, as knowledge of this entity builds up. Above all, AIP is a very attractive disease to clinicians in terms of its dramatic response to the oral steroid therapy in contrast to ordinary chronic pancreatitis. Although many characteristic findings of AIP have been described, definite diagnostic criteria have not been fully established. In the year 2002, the Japan Pancreas Society published the diagnostic criteria of AIP and many clinicians around the world use these criteria for the diagnosis of AIP. The diagnostic criteria proposed by the Japan Pancreas Society, however, are not completely satisfactory and some groups use their own criteria in reporting AIP. This review discusses several potential limitations of current diagnostic criteria for this increasingly recognized condition. The manuscript is organized to emphasize the need for convening a consensus to develop improved diagnostic criteria.

    Pancreas-associated enteric duplication cysts are rare developmental anomalies that communicate with the main pancreatic duct and may be associated with recurrent acute and chronic abdominal pain in children. In adults, these lesions may masquerade as pancreatic pseudocysts or pancreatic cystic neoplasms. An adult patient with a pancreas-associated enteric duplication is described which represents the first reported instance of association with both chronic calcific pancreatitis and pancreatic cancer. The clinical spectrum of pancreas-associated enteric duplication cyst, including diagnostic and therapeutic options, is reviewed.

    BACKGROUND: Some patients with chronic pancreatitis (CP) may require surgery mainly because of intractable pain, suspicion of malignancy, or complications related to CP. This study aimed to analyze the efifcacy of surgical treatment for patients with CP in terms of pain relief, control of local complications, and pancreatic endocrine/exocrine function. METHODS: Twenty-six patients with CP were treated surgically at our hospital from June 1985 to November 2005. The clinical data of these patients were analyzed retrospectively. RESULTS:  The follow-up time ranged from 8 to 130 months with a median of 60.6 months. No patients were lost to follow-up. All patients had improvement of clinical symptoms such as abdominal pain, steatorrhea and weight loss, to some degree, especially pain relief in patients with good dilation and high pressure of the main pancreatic duct. The endocrine and exocrine functions were not alleviated in all patients, otherwise the impaired glucose tolerance was improved in 8 (30.8%), 15 (57.7%) maintained the same body weight, one (3.8%) had an acute attack of CP, and 2 (7.7%) developed pancreatic carcinoma in the 16th and 28th month postoperatively and died within 3 years after operation for CP. The 1-, 3-, 5-year pain-free rates of CP patients were 96.2%(25/26), 88.5%(23/26) and 84.6%(22/26), respectively. CONCLUSIONS: In selected patients with CP, surgical treatment is a safe procedure and can effectively relieve pain and control local complications;also, it is helpful to improve the quality of life for patients with pancreatitis, and to control the development of this disease.

    Although medical treatment and endoscopic interven-tions are primarily offered to patients with chronic pancreatitis, approximately 40% to 75% will ultimately require surgery during the course of their disease. Al-though pancreaticoduodenectomy has been considered the standard surgical procedure because of its favorable results on pain control, its high postoperative complica-tion and pancreatic exocrine or/and endocrine dysfunc-tion rates have led to a growing enthusiasm for duodenal preserving pancreatic head resection. The aim of this review is to better understand the rationale underlying of the Frey procedure in chronic pancreatitis and to ana-lyze its outcome. Because of its hybrid nature, combin-ing both resection and drainage, the Frey procedure has been conceptualized based on the pathophysiology of chronic pancreatitis. The short and long-term outcome, especially pain relief and quality of life, are better after the Frey procedure than after any other surgical proce-dure performed for chronic pancreatitis.

    Full Text Available Background. Processes that could precede the development of pancreatic ductal adenocarcinoma are not well understood. Objective. Pathomorphological characteristics of the structural remodeling of the ductal apparatus of pancreas in patients with chronic pancreatitis, considering features of the ductal hypertension, proliferative and apoptotic activity of ductal epithelium. Methods. Complex pathomorphological study of pancreatic biopsies of 16 patients with severe pancreatic fibrosis at a chronic pancreatitis was performed. 10 patients had signs of pancreatic duct dilation, confirmed by ultrasound diagnostic, while in other patients ductal hypertension was not accompanied with the duct dilation. Immunohistochemical markers Ki-67 and Caspase-3 were used to detect proliferative and apoptotic activity, respectively. Results. Main morphological changes were manifested as: the concentric periductal fibrosis and local stenosis, the dysplastic changes of ductal epithelium with low level of proliferative activity and caspase -3 expression (in patients with pancreatic duct dilation; the cystic dilation of small and medium-sized intralobular ducts with low levels of Ki-67 and caspase-3 expression (in patients with ductal hypertension, but without pancreatic duct dilation; pancreatic intraepithelial neoplasia (PanIN is accompanied with the excessive nuclear Ki-67 expression and the low cytoplasmic caspase-3 levels. Conclusion. Structural remodeling of the pancreatic ductal system during chronic pancreatitis were not associated with rising of Ki-67 or Caspase-3 expression levels, unless in case of pancreatic intraepithelial neoplasia.

    ERP was analyzed in 87 patients with chronic pancreatitis with special reference to its clinical value in management of pain, the dominating symptom in uncomplicated chronic pancreatitis. A significant correlation was found between ductal changes due to pancreatitis and decrease in pancreatic function. However, no association was found between severe pancreatic pain and pancreatic function or pancreatic morphology. The significance of ERP in management of patients with persistent severe pancreatic pain is discussed.

The aims were to discuss a selection of landmark papers in chronic pancreatitis (CP) that influence modern management and to conclude by suggesting some future directions. This is based on that presentation. We will specifically review the following: duct anatomy and pancreas divisum, description of chronic relapsing pancreatitis and its differentiation from recurrent acute pancreatitis and established CP (ECP), natural histories and gene discoveries of alcoholic, idiopathic and hereditary pancreatitis, development of pancreatic cancer in CP, exocrine pancreatic insufficiency and calculation of dose and delivery of enzymes, endoscopic ultrasonography, and autoimmune pancreatitis. With some exceptions, we exclude basic science and surgery.

    One of the most challenging issues arising in patients with chronic pancreatitis is the management of abdominal pain. Many competing theories exist to explain pancreatic pain including ductal hypertension from strictures and stones, increased interstitial pressure from glandular fibrosis, pancreatic neuritis, and ischemia. This clinical problem is superimposed on a background of reduced enzyme secretion and altered feedback mechanisms. Throughout history, investigators have used these theories to devise methods to combat chronic pancreatic pain including: Lifestyle measures, antioxidants, analgesics, administration of exogenous pancreatic enzymes, endoscopic drainage procedures, and surgical drainage and resection procedures. While the value of each modality has been debated over the years, pancreatic enzyme therapy remains a viable option. Enzyme therapy restores active enzymes to the small bowel and targets the altered feedback mechanism that lead to increased pancreatic ductal and tissue pressures, ischemia, and pain. Here, we review the mechanisms and treatments for chronic pancreatic pain with a specific focus on pancreatic enzyme replacement therapy. We also discuss different approaches to overcoming a lack of clinical response update ideas for studies needed to improve the clinical use of pancreatic enzymes to ameliorate pancreatic pain.

    Full Text Available Abstract Pancreatic neuroendocrine tumors are a rare entity with an incidence between 2 per million to 5 per 100 000. Association with pancreatitis (acute or chronic is rare and is considered to be determined by the tumoral obstruction of pancreatic ducts, but sometimes occurs without any apparent relationship between them. Non-functional neuroendocrine pancreatic tumors are usually diagnosed when either very large or metastatic. Small ones are occasionally diagnosed when imagery is performed for other diagnostic reasons. Intraoperative discovery is even rarer and poses problems of differential diagnosis with other pancreatic tumors. Association with chronic pancreatitis is rare and usually due to pancreatic duct obstruction by the tumor. We describe the case of a patient with a small non-functioning neuroendocrine tumor in the pancreatic tail accidentally discovered during surgery for delayed traumatic splenic rupture associated with chronic alcoholic pancreatitis. The tumor of 1.5cm size was well differentiated and confined to the pancreas, and was resected by a distal splenopancreatectomy. Conclusions Surgeons should be well aware of the rare possibility of a non-functional neuroendocrine tumor in the pancreas, associated with chronic pancreatitis, surgical resection being the optimal treatment for cure. Histopathology is of utmost importance to establish the correct diagnosis, grade of differentiation, malignancy and prognosis.

    We systematically reviewed the clinical trials which recruited antioxidants in the therapy of pancreatitis and evaluated whether antioxidants improve the outcome of patients with pancreatitis. Electronic bibliographic databases were searched for any studies which investigated the use of antioxidants in the management of acute pancreatitis (AP) or chronic pancreatitis (CP) and in the prevention of post-endoscopic retrograde cholangio-pancreatography (post-ERCP) pancreatitis (PEP) up to February 2009. Twenty-two randomized, placebo-controlled, clinical trials met our criteria and were included in the review. Except for a cocktail of antioxidants which showed improvement in outcomes in three different clinical trials, the results of the administration of other antioxidants in both AP and CP clinical trials were incongruent and heterogeneous. Furthermore, antioxidant therapy including allopurinol and N-acetylcysteine failed to prevent the onset of PEP in almost all trials. In conclusion, the present data do not support a benefit of antioxidant therapy alone or in combination with conventional therapy in the management of AP, CP or PEP. Further double blind, randomized, placebo-controlled clinical trials with large sample size need to be conducted.

    Pancreatic stellate cells (PSCs) and other pancreatic components that play a critical role in exocrine pancreatic diseases are generally identified separately by conventional studies, which provide indirect links between these components. Here, nonlinear optical microscopy was evaluated for simultaneous characterization of these components within a three-dimensional (3-D) tissue environment, primarily based on multichannel detection of intrinsic optical emissions and cell morphology. Fresh rat pancreatic tissues harvested at 1 day, 7 days, and 28 days after induction of chronic pancreatitis were imaged, respectively. PSCs, inflammatory cells, blood vessels, and collagen fibers were identified simultaneously. The PSCs at day 1 of chronic pancreatitis showed significant enlargement compared with those in normal pancreas (pdiseases, leading to more effective treatments.

    There was investigated a hepatic bile in 50 persons, aged 35-58 years old, including 20--practically healthy persons (I group), 20 patients, suffering chronic fibrose-degenerative pancreatitis (CHFDP) without jaundice syndrome (II group) and 10 patients, suffering CHFDP with jaundice syndrome (III group). There were determined the contents of the bile acids, the lipids and electrolytic contents of bile. A trustworthy difference in the bile contents was registered in patients, suffering CHFDP with the jaundice syndrome and without it, comparing with such in healthy persons. This have had permitted to add the complex of medicinal preoperative preparation of these patients substantially, and to apply the electrolytes content of a bile to apply as an additional diagnostic marker.

    In an era such as the present one in which there is a high demand for health services with the associated pressure of controlling spending, health care organizations are concerned about the cost-effectiveness of quality improvement interventions. On the other hand,the impact of the disease and the treatment on the patient's overall well-being and functioning has become a topic of growing interest not only in clinical research but also in practice. The clinical evaluation of the benefits of specific treatments for chronic, debilitating and incurable diseases should increasingly include formal assessment of patient activity and well-being. Thus, health-related quality of life as subjectively perceived by the patient,is becoming a major issue in the evaluation of any therapeutic intervention, mainly in patients with chronic or difficult diseases where the aim of the intervention is to keep patients either symptom-free and capable of living in the community for a long time or to reduce the discomfort caused by the disease. In this paper,we review the current knowledge on the quality of life assessment in chronic pancreatitis patients.

    AIM: To evaluate the ability of the time-signal intensity curve (TIC) of the pancreas obtained from dynamic contrast-enhanced magnetic resonance imaging (MRI) for differentiation of focal pancreatic masses, especially pancreatic carcinoma coexisting with chronic pancreatitis and tumor-forming pancreatitis.METHODS: Forty-eight consecutive patients who underwent surgery for a focal pancreatic mass, including pancreatic ductal carcinoma (n = 33), tumor-forming pancreatitis (n = 8), and islet cell tumor (n = 7), were reviewed. Five pancreatic carcinomas coexisted with longstanding chronic pancreatitis. The pancreatic TICs were obtained from the pancreatic mass and the pancreatic parenchyma both proximal and distal to the mass lesion in each patient, prior to surgery, and were classified into 4 types according to the time to a peak: 25 s and 1, 2, and 3 min after the bolus injection of contrast material, namely, type-Ⅰ,Ⅱ,Ⅲ,and IV, respectively, and were then compared to the corresponding histological pancreatic conditions.RESULTS: Pancreatic carcinomas demonstrated type-m (n = 13) or IV (n = 20) TIC. Tumor-forming pancreatitis showed type-Ⅱ(n = 5) or Ⅲ(n = 3) TIC. All islet cell tumors revealed type-1. The type-IV TIC was only recognized in pancreatic carcinoma, and the TIC of carcinoma always depicted the slowest rise to a peak among the 3 pancreatic TICs measured in each patient, even in patients with chronic pancreatitis.CONCLUSION: Pancreatic TIC from dynamic MRI provides reliable information for distinguishing pancreatic carcinoma from other pancreatic masses, and may enable us to avoid unnecessary pancreatic surgery and delays in making a correct diagnosis of pancreatic carcinoma, especially, in patients with longstanding chronic pancreatitis.

    A casual relation between pancreatic pressure and pain has been searched for decades but lack of appropriate methods for pressure measurements has hindered progress. During the 1980's the needle method has been used for direct intraoperative pancreatic tissue fluid pressure measurements and later...... for percutaneous sonographically-guided pressure measurements. Clinical and experimental evaluation of the method showed comparable results at intraoperative and percutaneous measurements and little week-to-week variation. Furthermore, comparable pressures in duct and adjacent pancreatic tissue were found, i.......e. the needle pressure mirrors the intraductal pressure. Comparisons of pain registrations, morphological and functional parameters with pancreatic tissue fluid pressure measurements have revealed a relation between pressure and pain which probably is causal. In patients with pain the high pressures previously...

    Full Text Available Context: Chronic pancreatitis is an inflammatory condition that may result in progressive parenchymal damage and fibrosis which can ultimately lead to destruction of pancreatic tissue. Fistulas to the pleura, peritoneum, pericardium, and peripancreatic organs may form as a complications of pancreatitis. This case report describes an exceedingly rare complication, pancreaticoureteral fistula (PUF. Only two additional cases of PUF have been reported. However, they evolved following traumatic injury to the ureter or pancreatic duct. No published reports describe PUF as a complication of pancreatitis. Case Report: A 69-year-old Hispanic female with a past medical history of cholecystectomy, pancreatic pseudocyst, and recurrent episodes of pancreatitis presented with severe, sharp, and constant abdominal pain. Upon imaging, a fistulous tract was visualized between the left renal pelvis (at the level of an upper pole calyx and the pancreatic duct and a ureteral stent was placed to facilitate fistula closure. Following the procedure, the patient attained symptomatic relief and oral intake was resumed. A left retrograde pyelogram was repeated 2 months after the initial stent placement and demonstrating no evidence of a persistent fistulous tract. Conclusion: Due to PUF′s unclear etiology and possible variance of presentation, it is important for physicians to keep this rare complication of pancreatitis in mind, especially, when evaluating a patient with recurrent pancreatitis, urinary symptoms and abnormal imaging within the urinary collecting system and pancreas.

There is no consensus on the measurement of pain, making comparison of observational...... studies difficult, and little attention has been paid to the type and amount of analgesics used by patients before and after decompressive treatment. METHODS: We performed a retrospective study of all patients with chronic pancreatitis and large-duct disease and receiving decompressing treatment between 1...... November 1994 and 31 July 1999. Primary parameters were type and amount of analgesics used. RESULTS: Forty-nine patients with chronic pancreatitis and large-duct disease received stenting of the pancreatic duct (28 patients), ESWL (6 patients) or both (15 patients). After a median follow-up of 21 months...

    Full Text Available CONTEXT: Necrotizing pancreatitis is the most serious form of pancreatic inflammatory disease leading to multiorgan failure and a high (15-20% mortality rate. The poor nutritional and metabolic conditions and secondary bacterial translocation raise the mortality rate even more. OBJECTIVE: The aim of the study was to evaluate the effect of jejunal feeding in cases of chronic pancreatitis with extended necrosis. PATIENTS: In our institution, over a five-year period, 86 patients with severe necrotizing pancreatitis were treated for extended necrosis. In 19 patients, chronic calcifying pancreatitis was demonstrated by computed tomography showing more than 20% necrosis in the residual pancreas as well. SETTING: In 12 cases, nutrition was provided by jejunal feeding using an endoscopically placed nasojejunal feeding tube, whereas in 7 cases, hypocaloric parenteral nutrition was used. DESIGN: Retrospective unicenter study. MAIN OUTCOME MEASURES: The rate of healing with conservative treatment. RESULTS: Two of the 12 jejunally fed patients were operated on because of complications of pancreatitis. Five patients required intervention in the hypocaloric parenteral nutrition group: 4 were operated on and one more needed endoscopic intervention. The healing rate was significantly higher (P=0.045 in the jejunal feeding group (83.3% than in the parenteral nutrition (28.6% patients. CONCLUSIONS: In cases of chronic calcifying pancreatitis serious necrosis can develop in the residual pancreas resulting in a severe acute pancreatitis-like disease. A better healing rate was achieved and less interventions became necessary using nasojejunal tube feeding than in the parenteral nutrition group and this was analogous to what was observed in severe necrotizing pancreatitis This form of pancreatitis has not yet been described in the literature in detail. The authors suggest that it be regarded as a separate entity.

  18. Chronic pancreatitis: Maldigestion, intestinal ecology and intestinal inflammation

    Exocrine pancreatic insufficiency caused by chronic pancreatitis results from various factors whichregulate digestion and absorption of nutrients. Pancreatic function has been extensively studied over the last 40 years, even if some aspects of secretion and gastrointestinal adaptation are not completely understood. The main clinical manifestations of exocrine pancreatic insufficiency are fat malabsorption, known as steatorrhea, which consists of fecal excretion of more than 6 g of fat per day, weightloss, abdominal discomfort and abdominal swelling sensation. Fat malabsorption also results in a deficit of fat-soluble vitamins (A, D, E and K) with consequent clinical manifestations. The relationships between pancreatic maldigestion, intestinal ecology and intestinal inflammation have not received particular attention, even if in clinical practice these mechanisms may be responsible for the low efficacy of pancreatic extracts in abolishing steatorrhea in some patients. The best treatments for pancreatic maldigestion should be re-evaluated, taking into account not only the correction of pancreatic insufficiency using pancreatic extracts and the best duodenal pH to permit optimal efficacy of these extracts, but we also need to consider other therapeutic approaches including the decontamination of intestinal lumen, supplementation of bile acids and, probably, the use of probiotics which may attenuate intestinal inflammation

    Chronic pancreatitis is an inflammatory disease associated with structural and functional damage of the pancreas. In most cases pain, maldigestion and weight loss are the leading symptoms, which significantly worsen the quality of life. Correct diagnosis and differential diagnosis of chronic pancreatitis and treatment of these patients requires up-to-date and evidence based treatment guidelines. The Hungarian Pancreatic Study Group proposed to prepare an evidence based guideline based on the available international guidelines and evidence. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and complemented and/or modified the international guidelines if it was necessary. 123 relevant clinical questions in 11 topics were defined. Evidence was classified according to the UpToDate® grading system. The draft of the guidelines were presented and discussed at the consensus meeting in September 12, 2014. All clinical questions were accepted with total or strong agreement. The present guideline is the first evidence based guideline for chronic pancreatitis in Hungary. This guideline provides very important and helpful data for tuition, everyday practice and proper financing of chronic pancreatitis. Therefore, the authors believe that these guidelines will widely become a basic reference in Hungary.

    Chronic pancreatitis(CP) is a chronic inflammatory disease of the pancreas. The main symptom of patients with CP is chronic and severe abdominal pain. However, the pathophysiology of pain in CP remains obscure.Traditionally, researchers believed that the pain was caused by anatomical changes in pancreatic structure. However, treatment outcomes based on such beliefs are considered unsatisfactory. The emerging explanations of pain in CP are trending toward neurobiological theories. This article aims to review current evidence regarding the neuropathophysiology of pain in CP and its potential implications for the development of new treatments for pain in CP.

    Endoscopic ultrasonography (EUS) can be a useful tool for detecting underlying causes of acute pancreatitis and establishing the severity of fibrosis in chronic pancreatitis. Ancillary techniques include fine needle aspiration and core biopsy, bile collection for crystal analysis, pancreatic function testing, and celiac plexus block. This review focuses on the role of EUS in the diagnosis of acute and chronic pancreatitis.

  2. Etiology of chronic pancreatitis: Has it changed in the last decade?

    2009-01-01

    The evidence from recent surveys on chronic pancreatitis carried out around the world shows that alcohol remains the main factor associated with chronic pancreatitis, even if at a frequency lower than that reported previously. It has further confirmed that heavy alcohol consumption and smoking are independent risk factors for chronic pancreatitis. Autoimmune pancreatitis accounts for 2%-4% of all forms of chronic pancreatitis, but this frequency will probably increase over the next few years. The rise in idiopathic chronic pancreatitis, especially in India, represents a black hole in recently published surveys. Despite the progress made so far regarding the possibility of establishing the hereditary forms of chronic pancreatitis and the recognition of autoimmune pancreatitis, it is possible that we are more inaccurate today than in the past in identifying the factors associated with chronic pancreatitis in our patients.

    Pancreatic cancer is a challenging disease for patients, doctors and researchers who for decades have searched for a cure for this deadly malignancy. Although existing mouse models of pancreatic cancer have shed light on the mechanistic basis of the neoplastic conversion of the pancreas, their impact in terms of offering new diagnostics and therapeutic modalities remains limited. Chronic pancreatitis is an inflammatory disease of the pancreas that is associated with a gradual damage of the organ and an increased risk of developing neoplastic lesions. In this review, we propose that detailed studies of chronic inflammatory processes in the pancreas will provide insights into the evolution of pancreatic cancer. This information may prove useful in the design of effective therapeutic strategies to battle the disease.

    Full Text Available Context The small intestine in chronic pancreatitis has not been investigated yet thoroughly. It would be important to understand fat metabolism in the course of this disease and could be explained if the small intestine has some pathological conditions and, due to this reason, pancreatic enzyme substitution does not work in all patients. Objective To investigate the pathophysiology of small intestine in chronic pancreatitis and to show the reason why in some cases pancreatic enzyme substitution does not work properly. Patients In the process of the study 33 chronic pancreatitis patients have been examined. Controls The control group includes 30 subjects without chronic pancreatitis similar for age, sex and alcohol consumption to the patients with chronic pancreatitis patients. Investigations Aspiration biopsy of jejunum mucosa followed by histological examination and investigation of intestinal enzymes by aspiration has been performed. Main outcome measures Metabolism at membranic level has been studied by enzymatic activity of amylase and lipase in the small intestine. Production of enzymes (monoglyceride lipase, lactase, saccharase, maltase, glycyl-lleucine dipeptidase promoting metabolism in enterocytes has been estimated as to their activity in homogenates of jejunum mucosasamples. Participation of mucosa in intestinal digestion has been assessed by alkaline phosphatase activity in a secretory chyme from proximal portion of jejunum. Absorptive capacity of jejunum was evaluated by D-xylose test results. DNA, lysozyme, immunoglobulin contents of chyme have also been calculated and bacteriological study of chyme has been also performed. Results Secondary enteritis, accompanied by moderate dystrophic changes of mucous membrane, thinning of limbus, and decrease of Paneth cell mitotic index, was found to occur in chronic pancreatitis patients. Enteritis is followed by changes in enzymatic processes in the sphere of membrane and intestinal

    2012-08-01

    Full Text Available The relationship between pancreatic fibrosis and apoptosis of pancreatic acinar cells has not been fully elucidated. We reported that taurine had an anti-fibrotic effect in a dibutyltin dichloride (DBTC-chronic pancreatitis model. However, the effect of taurine on apoptosis of pancreatic acinar cells is still unclear. Therefore, we examined apoptosis in DBTC-chronic pancreatitis and in the AR42J pancreatic acinar cell line with/without taurine. Pancreatic fibrosis was induced by a single administration of DBTC. Rats were fed a taurine-containing diet or a normal diet and were sacrificed at day 5. The AR42J pancreatic acinar cell line was incubated with/without DBTC with taurine chloramines. Apoptosis was determined by using terminal deoxynucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling (TUNEL assay. The expression of Bad and Bcl-2 proteins in the AR42J cells lysates was detected by Western blot analysis. The apoptotic index of pancreatic acinar cells in DBTC-administered rats was significantly increased. Taurine treatment inhibited pancreatic fibrosis and apoptosis of acinar cells induced by DBTC. The number of TUNEL-positive cells in the AR42J pancreatic acinar cell lines was significantly increased by the addition of DBTC. Incubation with taurine chloramines ameliorated these changes. In conclusion, taurine inhibits apoptosis of pancreatic acinar cells and pancreatitis in experimental chronic pancreatitis.

    Full Text Available Management of internal pancreatic fistula is challenging because it is a rare and uncommon complication of chronic pancreatitis. The aim of this study was to evaluate the efficiency of the different ways of diagnostics and treatment for internal pancreatic fistula. Material and methods The prospective analysis of surgical treatment of the internal pancreatic fistula among 39 patients was carried out. Patients’ data, diagnostic findings and surgical procedure were analyzed. The comparative estimation of surgical interventions was executed using questionnaire SF-36 v2тм. Results The results of the current study demonstrate good facilities of computed tomography, magnetic resonance cholangiopancreatography (92.3% for determination of internal pancreatic fistula. 28 patients underwent Frey’s procedure, 8 - cystopancreatojejunal anastomosis using Roux-en-Y loop, 3 - combination of Frey’s procedure and cystopancreatojejunal. Total morbidity and mortality was 12.8% and 2.6% respectively. We admitted significant improvement in comparison of life quality before and after operation (p<0.01. Conclusion Surgery remains an excellent and safe option for patients suffering from internal pancreatic fistula in chronic pancreatitis with significant improvement in their quality of life.

    Objective Evaluation of the efficacy of pancreatic resections for the treatment of chronic pains during chronic pancreatitis. Methods Retrospective study of inpatients for chronic pancreatitis between 1982 to 2000. Purpose of admission, morphological changes, treatments and results were evaluated. Results 142 patients were admitted for chronic pancreatitis. 111 patients suffered from chronic pains, due to morphological changes such as pseudocysts, inflammatory masses in the head, dilated pancreatic ducts, biliary or duodenal compressions. Denervations were never efficient, pancreatic resections achieved relief of pain in up to 75% of cases and drainages were efficient in 52% of cases. Conclusions Pancreatic resections during chronic pancreatitis seem to be the most efficient treatment of chronic pains. New techniques such as duodenum-preserving head resection or total pancreatectomy with islet autotransplantation should improve these results.

    Obstructive jaundice is very rarely caused by impaction of a pancreatic stone in the papilla. We report here on a case of obstructive jaundice with acute cholangitis that was caused by an impacted pancreatic stone in the papilla in a patient with chronic pancreatitis. A 48-year-old man presented with acute obstructive cholangitis. Abdominal computed tomography with the reconstructed image revealed distal biliary obstruction that was caused by a pancreatic stone in the pancreatic head, and there was also pancreatic ductal dilatation and parenchymal atrophy of the pancreatic body and tail with multiple calcifications. Emergency duodenoscopy revealed an impacted pancreatic stone in the papilla. Precut papillotomy using a needle knife was performed, followed by removal of the pancreatic stone using grasping forceps. After additional sphincterotomy, a large amount of dark-greenish bile juice gushed out. The patient rapidly improved and he has remained well.

    AIM: To investigate c-met expression during early pancreatic carcinogenesis.METHODS: We used 46 bulk tissues and 36 microdissected samples, including normal pancreas, chronic pancreatitis, and pancreatic cancer, for quantitative real time reverse transcription-polymerase chain reaction.RESULTS: In bulk tissue analyses, pancreatic cancer tissues expressed significantly higher levels of c-met than did chronic pancreatitis and normal pancreas tissues.c-met levels did not differ between chronic pancreatitis and normal pancreas tissues. In microdissection-based analyses, c-met was expressed at higher levels in microdissected pancreatic cancer cells and pancreatitisaffected epithelial cells than in normal ductal epithelial cells (both, P < 0.01). Interestingly, pancreatitis-affected epithelial cells expressed levels of c-met similar to those of pancreatic cancer cells.CONCLUSION: Overexpression of c-met occurs during the early stage of pancreatic carcinogenesis, and a single alteration of c-met expression is not sufficient for progression of chronic pancreatitis-affected epithelial cells to pancreatic cancer cells.

    Chronic pancreatitis is a relatively common disease. We encountered two different cases of belatedly demonstrated pancreatic carcinoma featuring underlying chronic pancreatitis. The first case was one that was highly suspected as that of a malignancy based upon imaging study, but unfortunately, it could not be confirmed by intra-operative cytology at that time. Following this, the surgeon elected to perform only conservative bypass surgery for obstructive biliary complication. Peritoneal carcinomatosis was later noted and the patient finally died. The second case, a malignant mucinous neoplasm,was falsely diagnosed as a pseudocyst, based upon the lesion's sonographic appearance and associated elevated serum amylase levels. After suffering repeated hemoptysis,the patient was found to exhibit lung metastasis and peritoneal seeding. We reviewed some of the literature,including those studies discussing chronic pancreatitis predisposing to a malignant change. These two case analyses illustrate clearly that the diagnosis for such conditions, which is simply based upon imagery or pathological considerations may end up being one of a mistaken malignancy. Some of our suggestions for the treatment of such malignancies as revealed herein include,total pancreatomy for univocal mass lesion, and needle aspiration of lesion-contained tissue for amylase, CA199and CEA levels for a suspicious cystic pancreatic mass.

The use of porcine pancreatic enzymes for the correction of exocrine insufficiency is governed by the pathophysiology of the disease as well as pharmacologic properties of PES. Variability in bioequivalence of PES has been noted on in vitro and in vivo testing and has been attributed to the differences in enteric coating and the degree of micro-encapsulation. As a step towards standardizing pancreatic enzyme preparations, the Food and Drug Administration now requires the manufacturers of PES to obtain approval of marketed formulations by April 2010. In patients with treatment failure, apart from evaluating drug and dietary interactions and compliance, physicians should keep in mind that patients may benefit from switching to a different formulation. The choice of PES (enteric coated versus non-enteric coated and the need for acid suppression should be individualized. There is no current standard test for evaluating adequacy of therapy in CP patients and studies have shown that optimization of therapy based on symptoms may be inadequate. Goals of therapy based on overall patient presentation and specific laboratory tests rather than mere correction of steatorrhea are needed.Keywords: pancreatic exocrine insufficiency, chronic pancreatitis, pancreatic enzyme supplement

    Progress made in identifying the genetic susceptibility underlying acute and chronic pancreatitis has benefitted the clinicians in understanding the pathogenesis of the disease in a better way. The identification of mutations in cationic trypsinogen gene (PRSS1 gene; functional gain mutations) and serine protease inhibitor kazal type 1 (SPINK1 gene; functional loss mutations) and other potential susceptibility factors in genes that play an important role in the pancreatic secretory functions or response to inflammation during pancreatic injury has changed the current concepts and understanding of a complex multifactorial disease like pancreatitis. An individual's susceptibility to the disease is governed by genetic factors in combination with environmental factors. Candidate gene and genetic linkage studies have identified polymorphisms in cationic trypsinogen (PRSS1), SPINK1, cystic fibrosis trans-membrane conductance regulator (CFTR), Chymotrypsinogen C (CTRC), Cathepsin B (CTSB) and calcium sensing receptor (CASR). Individuals with polymorphisms in the mentioned genes and other as yet identified genes are at an enhanced risk for the disease. Recently, polymorphisms in genes other than those involved in "intra-pancreatic trypsin regulatory mechanism" namely Claudin-2 (CLDN2) and Carboxypeptidase A1 (CPA1) gene have also been identified for their association with pancreatitis. With ever growing number of studies trying to identify the genetic susceptibility in the form of single nucleotide polymorphisms, this review is an attempt to compile the available information on the topic.

  10. Critical Review of Diagnostic Methods Used in Chronic Pancreatic Disease

    1995-01-01

    Full Text Available This paper provides a balanced assessment of the various pancreatic function tests and imaging techniques used in the differential diagnosis of chronic pancreatic disease. Function tests that study the digestive capacity of the pancreas (fat absorption of dietary lipids, fluorescein- or radiolabelled fats, bentiromide test, etc have high specificity, but very low sensitivity. This is because 90% of pancreas has to be destroyed before steatorrhea or creatorrhea occurs. Tests that directly measure pancreatic bicarbonate and protein secretion (secretin test, etc are more accurate and may detect pancreatic dysfunction even before anatomical changes occur. Measurement of pancreatic enzymes in serum or urine, or the decreased decline of serum amino acids during their incorporation into pancreatic enzymes, are not sufficiently sensitive or specific to help diagnose pancreatic disease. Sensitive and specific tumour markers are not yet available. Thus screening tests are not cost-effective - if they are negative, they do not exclude pancreatic disease; and if positive, they have to be confirmed by more specific tests. Imaging techniques are the most commonly used methods of investigation. The usefulness of abdominal survey films, barium studies, percutaneous transhepatic cholangiography, endoscopic retrograde cholangiopancreatography (ERCP, ultrasonography, computed tomographic scan, magnetic resonance imaging and endoscopic ultrasonography is critically reviewed. Most of the radiological methods can be combined with cytology or biopsy. Histology demonstrating malignancy establishes this diagnosis, but negative biopsies do not exclude malignant tumours. Presently only ERCP and endoscopic ultrasound can diagnose cancers sufficiently early to allow for possible `curative' surgery, and only endoscopic ultrasound is capable to stage tumours for the assessment of resectability.

  11. H pylori infection causes chronic pancreatitis in Mongolian gerbils

    2007-01-01

    AIM: To investigate whether chronic H pylori infection has the potential to induce pancreatitis in the Mongolian gerbil model, and whether it is dependent on an intact type Ⅳ secretion system.METHODS: Mongolian gerbils were infected with wild type (WT) H pyloritype Ⅰ strain B128 or its isogenic mutant B128 Acag Y (defective type Ⅳ secretion). After seven months of infection, H pylori was reisolated from antrum and corpus and H pylori DNA was analyzed by seminested polymerase chain reaction (PCR). Inflammation and histological changes were documented in the gastric antrum, corpus, and pancreas by immunohistochemistry.Cytokine mRNA, gastric pH, plasma gastrin, amylase,lipase, and glucose levels were determined.RESULTS: The H pylori infection rate was 95%.Eight infected animals, but none of the uninfected group, developed transmural inflammation and chronic pancreatitis. Extensive interstitial fibrosis and inflammation of the pancreatic lobe adjacent to the antrum was confirmed by trichrome stain, and immunohistochemically. Pro-inflammatory cytokine mRNA was significantly increased in the antral mucosa of all infected gerbils. In the corpus, only cytokine levels of WT-infected animals and those developing transmural inflammation and pancreatitis were significantly increased.Levels of lipase, but not glucose or amylase levels, were significantly reduced in the pancreatitis group. H pylori DNA was detected in infected antral and corpus tissue,but not in the pancreas.CONCLUSION: H pylori infection is able to induce chronic pancreatitis in Mongolian gerbils independently of the type Ⅳ secretion system, probably by an indirect mechanism associated with a penetrating ulcer.

    Full Text Available Context Due to maldigestion, pancreatic exocrine insufficiency (PEI in chronic pancreatitis may lead to deficiencies in fat-soluble vitamins, including vitamin D. This may, in turn, can cause disturbances in bone metabolism and reduce bone mineral density. Objective To conduct a prospective study of maldigestion, bone metabolism, and bone mineral density in a group of patients with chronic pancreatitis. Methods A total of 50 male patients with proven chronic pancreatitis (36/50 alcohol; 42/50 smokers were studied. Pancreatic exocrine function was assessed using the fecal elastase-1 test. Blood and urine samples were analyzed for parameters related to pancreatitis, nutrition, endocrine status, and bone metabolism. Bone mineral density was measured with dual-energy X-ray absorption (DXA and conventional vertebral X-rays. A standardized questionnaire for osteoporosis was given. Results Twenty-eight of the patients had PEI (fecal elastase-1 200 µg/g, 25 had bone pain, and 21 had a history of bne fractures. Serum 25-OH-cholecalciferol and urine calcium were decreased and deoxypyridinoline concentrations were increased in urine. Serum calcium, bone-specific alkaline phosphatase, and parathyroid hormone were within normal limits. There was no statistical correlation between three classes of fecal elastase-1 (200 µg/g and calcium, 25-OH-cholecalciferol, or deoxypyridinoline. Of the 15 patients who underwent DXA, 5 had normal bone mineral density (T score >-1, 9 had osteopenia (T score from -1 to -2.5, and 1 had osteoporosis (T score -2.5. There was a trend toward a correlation between low fecal elastase-1 and low T scores (P=0.065. Low fecal elastase-1 correlated with low bone mineral density in conventional X-rays (p<0.05. Patients receiving pancreatic enzyme replacement therapy (PERT had significantly higher DXA values (p<0.05. Conclusions Patients with chronic pancreatitis have osteoporosis, along with abnormal bone metabolism and reduced bone

    Full Text Available Episodes of acute pancreatitis have been described during the course of ulcerative colitis and most of them are due to cholelithiasis or drugs. Idiopathic pancreatitis has rarely been associated with inflammatory bowel disease (IBD. We describe one such case. A 35-year-old male presented in 2001 with a ten year history of recurrent episodes of diarrhea without blood and mucus in the stools. Four years ago, he developed an episode of mild acute pancreatitis. At that time, the serum amylase level was three times the upper normal limit. He was treated conservatively. A month later, he was found to be diabetic and was put on insulin. He was non-alcoholic and there was no history of any chronic drug use. There was no similar family history.

    Pharmacological, percutaneous celiac plexus blockade is often inefficient in the treatment of pain in chronic pancreatitis. Lack of efficiency could be due to incomplete denervation of the plexus; however, a method for measuring the completeness of celiac plexus blockade is not yet available. We...... have, therefore, monitored the physiological completeness of pharmacological percutaneous celiac blockade with 40 ml 25% ethanol by measuring the effect of posture on heart rate, blood pressure, hepato-splanchnic vascular resistance, and pancreatic hormone concentrations before and after celiac plexus...... regarding pain after 1 week. In conclusion, pancreatic hormone concentrations in response to standing are not useful for monitoring celiac plexus block, whereas heart rate, blood pressure and hepato-splanchnic blood flow may yield useful information. From such measurements it was concluded that permanent...

    . It is unknown whether the incretin defect is a primary event leading to T2DM or arises as a consequence of the diabetic state. To investigate this we studied patients with chronic pancreatitis (CP). Over time, CP leads to secondary diabetes mellitus (DM). If patients with CP and secondary DM exhibit...... independently of the endocrine status of patients with CP, the incretin defect could represent a primary pathogenetic defect. Three protocols have been employed to investigate this. In a study investigating postprandial incretin responses in 8 patients with CP and exocrine pancreatic insufficiency......, with and without pancreatic enzyme supplementation (PES), we observed preserved incretin responses as compared to matched healthy subjects; and, further, that PES increased postprandial incretin responses in these patients. This suggests not only that the secretion of incretin hormones is regulated by the mere...

    Seventy-four patients underwent operation for chronic pancreatitis during a 22 year period at UCLA Hospital. Follow-up data obtained for 60% of these patients an average of 3.2 years postoperation were analyzed by computer for statistically significant benefit between paired operation combinations and the variables of pain relief, stool habits, alcohol use, readmission for pancreatitis, and narcotic use. The combined group of total and cephalic pancreaticoduodenectomy proved more effective with respect to pain relief and readmission (p less than 0.05) than the group that had pseudocyst drainage. The comparison of groups that underwent resection or ductal drainage showed no statistical differences for the above variables. Regardless of type of operation, if the patient had evidence of pancreatic calcifications and had abstained from alcohol postoperatively, the likelihood of a return to normal activity was more favorable (p less than 0.05).

    Pancreatic cancer cells intimately interact with a complex microenvironment that influences pancreatic cancer progression. The pancreas is innervated by fibers of the sympathetic nervous system (SNS) and pancreatic cancer cells have receptors for SNS neurotransmitters which suggests that pancreatic cancer may be sensitive to neural signaling. In vitro and non-orthotopic in vivo studies showed that neural signaling modulates tumour cell behavior. However the effect of SNS signaling on tumor progression within the pancreatic microenvironment has not previously been investigated. To address this, we used in vivo optical imaging to non-invasively track growth and dissemination of primary pancreatic cancer using an orthotopic mouse model that replicates the complex interaction between pancreatic tumor cells and their microenvironment. Stress-induced neural activation increased primary tumor growth and tumor cell dissemination to normal adjacent pancreas. These effects were associated with increased expression of invasion genes by tumor cells and pancreatic stromal cells. Pharmacological activation of β-adrenergic signaling induced similar effects to chronic stress, and pharmacological β-blockade reversed the effects of chronic stress on pancreatic cancer progression. These findings indicate that neural β-adrenergic signaling regulates pancreatic cancer progression and suggest β-blockade as a novel strategy to complement existing therapies for pancreatic cancer.

    Chronic pancreatitis is a disease of the pancreas in which recurrent inflammatory episodes result in replacement of pancreatic parenchyma by fibrous connective tissue. This fibrotic reorganization of the pancreas leads to a progressive exocrine and endocrine pancreatic insufficiency. In addition, characteristic complications arise, such as pseudocysts, pancreatic duct obstructions, duodenal obstruction, vascular complications, obstruction of the bile ducts, malnutrition and pain syndrome. Pain presents as the main symptom of patients with chronic pancreatitis. Chronic pancreatitis is a risk factor for pancreatic carcinoma. Chronic pancreatitis significantly reduces the quality of life and the life expectancy of affected patients. These guidelines were researched and compiled by 74 representatives from 11 learned societies and their intention is to serve evidence-based professional training as well as continuing education. On this basis they shall improve the medical care of affected patients in both the inpatient and outpatient sector. Chronic pancreatitis requires an adequate diagnostic workup and systematic management, given its severity, frequency, chronicity, and negative impact on the quality of life and life expectancy.

  3. Epidemiology, aetiology and outcome of acute and chronic pancreatitis: An update.

    2008-01-01

    Over the past decades several epidemiological studies have been published reporting on incidence trends, hospital admissions, etiological factors and outcome of both acute and chronic pancreatitis. Over time, the incidence of acute pancreatitis has increased in the Western countries. Also, the number of hospital admissions for both acute and chronic pancreatitis have increased. These upward time trends possibly reflect a change in the prevalence of main etiological factors (e.g. gallstones and alcohol consumption) and cofactors such as obesity and genetic susceptibility. Acute and chronic pancreatitis are associated with significant morbidity and mortality and a substantial use of health care resources. Although the case-fatality rate of acute pancreatitis decreased over time, the overall population mortality did not change for both acute and chronic pancreatitis. This chapter will focus on recent developments in the epidemiology, aetiology, natural course and outcome of both acute and chronic pancreatitis.

    The present study was intended to examine the spectrum of radiographic patterns of the stomach associated with acute and chronic pancreatitis and their complications. Subjects served for the study consisted of 70 cases of pancreatitis (36 cases in acute stage and 34 cases in chronic stage). Intramural and perigastric permeation of extravasated pancreatic enzymes and secondary inflammatory reaction that follows are responsible for the radiographic change observed. 1. Generalized rugal thickening and particularly selective mucosal prominences in greater curvature of body and antrum are characteristically seen in acute (14 of 36 cases- 39%) and chronic pancreatitis (11 of 34 cases- 32%) 2. The only finding of the chronic pancreatitis includes patterns mimicking limits plastica, indurated and nondistensible rugae induced by perigastric adhesion (11 of 34 cases- 32%) Familiarization with these patterns of involvement contributes to the radiographic diagnosis of acute pancreatitis and avoides serious diagnostic errors in case of chronic pancreatitis.

    The objective of this study was to characterize the clinical, clinicopathological, and histopathological findings of dogs with chronic pancreatitis. The necropsy database at Texas A&M University was searched for reports of dogs with histological evidence of chronic pancreatitis defined as irreversible histologic changes of the pancreas (i.e. fibrosis or atrophy). A reference necropsy population of 100 randomly selected dogs was used for signalment and concurrent disease comparisons. Cases were categorized as clinical or incidental chronic pancreatitis based on the presence of vomiting, decreased appetite, or both vs. neither of these signs. All archived pancreas samples were scored histologically using a published scoring system. Sixty-one dogs with chronic pancreatitis were included. The most frequent clinical signs were lethargy, decreased appetite, vomiting, and diarrhea. Compared to the reference necropsy population, chronic pancreatitis cases were more likely to be older, neutered, of the non-sporting/toy breed group, and to have concurrent endocrine, hepatobiliary, or neurological disease. Clinical cases had significantly higher histological scores for pancreatic necrosis and peripancreatic fat necrosis, and were significantly more likely to have hepatobiliary or endocrine disease as well as increased liver enzyme activities, or elevated cholesterol and bilirubin concentrations. In conclusion, clinical disease resulting from chronic pancreatitis might be related to the presence of pancreatic necrosis and pancreatic fat necrosis. The signalment, presentation, and concurrent diseases of dogs with chronic pancreatitis are similar to those previously reported for dogs with acute pancreatitis.

  6. Duodenal Acidity May Increase the Risk of Pancreatic Cancer in the Course of Chronic Pancreatitis: An Etiopathogenetic Hypothesis

    Directory of Open Access Journals (Sweden)

    Talamini G

    2005-03-01

    Full Text Available Chronic pancreatitis patients have an increased risk of developing pancreatic cancer. The cause of this increase has yet to be fully explained but smoking and inflammation may play an important role. To these, we must now add a new potential risk factor, namely duodenal acidity. Patients with chronic pancreatitis very often present pancreatic exocrine insufficiency combined with a persistently low duodenal pH in the postprandial period. The duodenal mucosa in chronic pancreas patients with pancreatic insufficiency has a normal concentration of s-cells and, therefore, the production of secretin is preserved. Pancreatic ductal cells are largely responsible for the amount of bicarbonate and water secretion in response to secretin stimulation. When gastric acid in the duodenum is not well-balanced by alkaline pancreatic secretions, it may induce a prolonged secretin stimulus which interacts with the pancreatic ductal cells resulting in an increased rate of ductular cell activity and turnover. N-Nitroso compounds from tobacco, identified in human pancreatic juice and known to be important carcinogens, may then act on these active cells, thereby increasing the risk of cancer. Duodenal acidity is probably of particular concern in patients who have undergone a duodenum-preserving pancreatic head resection, since, in this anatomic situation, pancreatic juice transits directly via the jejunal loop, bypassing the duodenum. Patients undergoing a Whipple procedure or side-to-side pancreaticojejunostomy are probably less critically affected because secretions transit, at least in part, via the papilla. If the duodenal acidity hypothesis proves correct, then, in addition to stopping smoking, reduction of duodenal acid load in patients with pancreatic insufficiency may help decrease the risk of pancreatic cancer.

  7. Pathogenesis and mechanisms of pain in chronic pancreatitis

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The pathology of chronic pancreatitis is well known but the early events leading to the condition are less certain. Common characteristics of chronic pancreatitis, including fibrosis, chronic inflammation, and disappearance of parenchyma, usually are well established by the time tissue can be studied. Characteristics of acute pancreatitis may co-exist. Some experts assert that chronic pancreatitis begins with acute pancreatitis. Others consider that chronic pancreatitis develops first, and acute attacks occur on this background. The pain associated with chronic pancreatitis can be initiated through a variety of mechanisms. Increased pressure may distort nerves, affect blood flow, change pH, and cause retention of noxious substances, initiating action potentials. Tissue destruction and inflammation release biologically active materials capable of activating afferent nerves. Furthermore, inflammation damages nerves directly, triggering neuropathic pain. Understanding the neural pathways in the periphery and central nervous system that transmit impulses interpreted as pain should suggest the best methods for alleviating pancreatic pain. Pain may be transmitted through splanchnic, vagus, spinal, and phrenic peripheral nerves. It may be relayed through the dorsal columns of the spinal cord in addition to the spinothalamic tract. New methods of treating pancreatic pain therefore are possible.%虽然慢性胰腺炎的病理已经十分清楚,但其早期的致病机制尚不明确.慢性胰腺炎的一般特点为纤维化,慢性炎症和胰腺实质的消失,这些特征会随着疾病的发展而逐渐出现,同时还伴有急性胰腺炎的症状.一些专家认为慢性胰腺炎继发于急性胰腺炎.另一些则认为慢性胰腺炎首先发生,急性胰腺炎则在此基础上发生.慢性胰腺炎所引起的疼痛可通过许多机制发生.增高的胰腺压力可干扰神经,影响血流,改变pH值,并引起有毒物质的潴留,激活动作电位.组织的

    Chronic pancreatitis results in exocrine and endocrine dysfunction, affecting normal digestion and absorption of nutrients. In individuals with chronic pancreatitis, nutrition status may be further affected by poor dietary intake, often related to alcoholism. However, some deficiencies may be overlooked, potentially leading to nutrition-related problems with bone health and fatigue. The aim of this article is to describe the deficiencies that occur and to propose an evidence-based algorithm for the nutrition assessment and treatment of patients with chronic pancreatitis.

  11. Endoscopic therapy for chronic pancreatitis: technical success, clinical outcomes, and complications.

    Kowalczyk, Lukasz M; Draganov, Peter V

    2009-04-01

    Chronic pancreatitis (CP) can cause failure of both the exocrine and endocrine portions of the gland. Pain is the most recalcitrant clinical complaint in CP. Generally, conservative measures are first attempted to manage pain. These include cessation of alcohol use and smoking, enzyme replacement therapy, and finally, opioid analgesia. Endoscopy can be employed to treat the pain and complications due to CP. The results of the only two prospective randomized controlled trials suggest that surgery has a more durable effect than endoscopic therapy in controlling pain. Both trials suffer from severe limitations, however, and endoscopy remains the preferred approach for many patients because of its minimally invasive nature. Endoscopic ultrasound celiac plexus block has limited value in helping to control pain. More randomized trials are needed, along with further technologic innovation to improve the current treatment modalities. When considering interventional therapy for a patient with CP, a tailored and multidisciplinary therapeutic approach should be taken.

    2016-01-01

    Full Text Available Atraumatic splenic rupture is a rare complication of a pancreatic pseudocyst (PP, described in the setting of chronic pancreatitis. There is common understanding, within the literature, that an inflammatory process at the tail of the pancreas may disrupt the spleen and result in such splenic complications. The authors present a case report of a 29-year-old male with a PP, associated with chronic pancreatitis. The patient had a history of excessive alcohol intake and presented to the emergency department with a short history of abdominal pain and vomiting. He denied any significant history of trauma and serum amylase levels were normal. An admission computed tomography (CT scan of the abdomen confirmed the presence of a PP in direct contact with the spleen. The CT also demonstrated a heterogenous hypodense area of the splenic hilum, along with perisplenic fluid. The patient was admitted for observation. His abdominal pain progressed, and he became haemodynamically unstable. An emergency ultrasound scan (USS at this time revealed intra-abdominal haemorrhage. A subsequent CT confirmed splenic rupture, which was managed surgically with a full recovery. Few such cases are documented within the literature and more understanding of preempting such events is needed.

    Intraductal papillary mucinous neoplasm (IPMN) is an increasingly reported entity. Extensive pancreatic calcification is generally thought to be a sign of chronic pancreatitis, but it may occur simultaneously with IPMN leading to diagnostic difficulties. We report a case of a patient initially diagnosed with chronic calcifying pancreatitis who was later shown to have a malignant IPMN. This case illustrates potential pitfalls in the diagnosis of IPMN in the case of extensive pancreatic calcification as well as clues that may lead the clinician to suspecting the diagnosis. The possible mechanisms of the relation between pancreatic calcification and IPMN are also reviewed.

    Chronic pancreatitis is typically a painful condition and it can be associated with a severe burden of disease. The pathogenesis of pain in this disorder is poorly understood and its treatment has been largely empirical, often consisting of surgical or other invasive methods, with an outcome that is variable and frequently unsatisfactory. Human and experimental studies have indicated a critical role for neuronal mechanisms that result in peripheral and central sensitization. The pancreatic nociceptor seems to be significantly affected in this condition, with increased excitability associated with downregulation of potassium currents. Some of the specific molecules implicated in this process include the vanilloid receptor, TRPV1, nerve growth factor, the protease activated receptor 2 and a variety of others that are discussed in this Review. Studies have also indicated novel therapeutic targets for this condition.

    AIM: To evaluate p53 protein overexpression and to measure serum CA19.9 concentrations in cytological diagnosis of patients with suspected pancreatic cancer.METHODS: 24 patients with suspected pancreatic cancer due to chronic pancreatitis, had a pancreatic mass determined by imaging methods. The serum CA19.9 concentration was measured by solid phase radioimmunoassay. On laparotomy,puncture biopsy was performed, and specimens were divided into two parts for cytological diagnosis and detection of p53 protein.RESULTS: Cytology offered a sensitivity of 0.63, a specificity of 1.00, and an accuracy of 0.63. p53 protein analysis offered a sensitivity of 0.44, a specificity of 1.00, and an accuracy of 0.73. CA19.9 offered a sensitivity of 0.44, a specificity of 0.80, and an accuracy of 0.67. The combined cytology and p53 protein analysis showed a sensitivity of 0.78, a specificity of 1.00, and an accuracy of 0.92. Cytology and CA19.9showed a sensitivity of 0.67, a specificity of 0.80, an accuracy of 0.67. combined cytology and p53 protein analysis and CA19.9 showed a sensitivity of 0.78, a specificity of 0.80,and an accuracy of 0.79.CONCLUSION: Superior to any single test, the combined approach is helpful for the differential diagnosis of pancreatic cancer complicated with chronic pancreatitis.The combined cytology and p53 protein analysis offers the best diagnostic efficacy.

    AIM: To identify the expression of Caspase-l(interleukin1.β converting enzyme) and its role in adenoma of the pancreas and chronic pancreatitis.METHODS: The expression of Caspase-1 was assessed in 42 pancreatic cancer tissue samples, 38 chronic pancreatitis specimens, and 9 normal pancreatic tissues by immunohistochemistry and Western blot analysis.RESULTS: Overexpression of Caspase-1 was observed in both disorders, but there were differences in the expression patterns in distinct morphologic compartments. Pancreatic cancer tissues showed a clear cytoplasmatic overexpression of Caspase-1 in tumor cells of 71% of the tumors, whereas normal pancreatic tissues showed only occasional immunoreactivity. In chronic pancreatitis, overexpression of Caspase-1 was found in atrophic acinar cells (89 %),hyperplastic ducts (87 %), and dedifferentiating acinar cells (84 %). Although in atrophic cells a clear nuclear expression was found, hyperplastic ducts and dedifferentiating acinar cells showed dear cytoplasmic expression. Western blot analysis revealed a marked expression of the 45 kDa precursor of Caspase-1 in pancreatic cancer and chronic pancreatitis (80 %and 86 %, respectively). Clear bands at 30 kDa, which suggested the p10-p20 heterodimer of active Caspase-1, were found in 60 % of the cancer tissue and 14 % of the pancreatitis tissue specimens, but not in normal pancreatic tissues.CONCLUSION: Overexpression of Caspase-1 is a frequent event in pancreatic disorders and its differential expression patterns may reflect two functions of the protease. One is its participation in the apoptotic pathway in atrophic acinar cells and tumor-surrounding pancreatitis tissue, the other is its possible role in proliferative processes in pancreatic cancer cells and hyperplastic duct cells and dedifferentiating acinar cells in chronic pancreatitis.

    Full Text Available Context Intraductal papillary mucinous neoplasms (IPMNs are a recently classified pancreatic neoplasm with an increasing incidence. IPMN is often misdiagnosed as chronic pancreatitis because of symptoms of relapsing abdominal pain, pancreatitis, and steatorrhea and imaging findings of a dilated pancreatic duct of cystic lesions that are frequently confused with pseudocysts. Early recognition of IPMN allows for prompt surgical resection before malignant transformation. Case reports We report two cases of patients with long histories of chronic pancreatitis (more than 15 years that went on to develop IPMN. Both patients presented with symptoms of abdominal pain, nausea, steatorrhoea and eventually weight loss. Biochemical and radiological findings were suggestive of chronic pancreatitis although no clear causes for this were identified. Both patients were followed up with multiple repeat scans with no reported sinister findings. Many years after the initial diagnosis of chronic pancreatitis, radiological investigations identified pathological changes suggestive of neoplastic development and histology confirmed IPMN. Conclusions The cases demonstrate the ongoing challenges in diagnosing and managing IPMN effectively; highlights the important aspects of epidemiology in differentiating chronic pancreatitis and IPMN; continues the discussion surrounding the relationship between IPMN and chronic pancreatitis.

    Portal vein thrombosis (PVT) is a relatively common complication in patients with liver cirrhosis, but several other causes might play an important role in PVT pathogenesis. We present a case of alcoholic chronic pancreatitis complicated by acute extensive PVT. The patient was managed conservatively with danaparoid sodium at first, but the thrombosis gradually extended. We then tried radiological intervention using the direct transhepatic and transjugular intrahepatic postsystemic shunt approaches. Although we were able to successfully catheterize the percutaneous transhepatic portal vein (PTP), we could not achieve recanalization of the portal vein. Therefore, PTP catheterization and systemic intravenous infusion of urokinase and heparin was performed to prevent further progression of the thrombosis and cavernous transformation was finally achieved. Computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a pancreatic stone which had possibly induced dilatation of the tail duct and formation of a pancreatic pseudocyst and caused intractable pancreatitis. We performed endoscopic retrograde cholangiopancreatography and placed a stent in the pancreatic duct, which completely cured the pancreatitis. Retrospectively, the previous CT with curved multi-planar reconstruction was reviewed and a fistula was detected between the pancreatic pseudocyst and splenic vein. We concluded that the etiology of the PVT was not only inflammatory extension from pancreatitis but also a fistula between the pancreatic duct and the splenic vein.

    Chronic pancreatitis (CP) is a devastating disease with no treatments. Experimental models have been developed to reproduce the parenchyma and inflammatory responses typical of human CP. For the present study, one objective was to assess and compare the effects of pancreatic duct ligation (PDL) to those of repetitive cerulein (Cer)-induced CP in mice on pancreatic production of bone morphogenetic protein-2 (BMP2), apelin, and parathyroid hormone-related protein (PTHrP). A second objective was to determine the extent of cross talk among pancreatic BMP2, apelin, and PTHrP signaling systems. We focused on BMP2, apelin, and PTHrP since these factors regulate the inflammation-fibrosis cascade during pancreatitis. Findings showed that PDL- and Cer-induced CP resulted in significant elevations in expression and peptide/protein levels of pancreatic BMP2, apelin, and PTHrP. In vivo mouse and in vitro pancreatic cell culture experiments demonstrated that BMP2 stimulated pancreatic apelin expression whereas apelin expression was inhibited by PTHrP exposure. Apelin or BMP2 exposure inhibited PTHrP expression, and PTHrP stimulated upregulation of gremlin, an endogenous inhibitor of BMP2 activity. Transforming growth factor-β (TGF-β) stimulated PTHrP expression. Together, findings demonstrated that PDL- and Cer-induced CP resulted in increased production of the pancreatic BMP2, apelin, and PTHrP signaling systems and that significant cross talk occurred among pancreatic BMP2, apelin, and PTHrP. These results together with previous findings imply that these factors interact via a pancreatic network to regulate the inflammation-fibrosis cascade during CP. More importantly, this network communicated with TGF-β, a key effector of pancreatic pathophysiology. This novel network may be amenable to pharmacologic manipulations during CP in humans.

    We report the case of a 70-year-old woman who consulted for recurrent short episodes of mild-to-moderate abdominal pain. Dilated main pancreatic duct was seen on CAT scan and magnetic resonance, with multiple calcifications and intraductal stones, typical in CP. However, for a more pronounced cystic dilatation in the pancreatic head, we could not exclude the coexistence of a main duct IPMN. ERCP was performed, with pancreatic sphincterotomy and extraction of pancreatic stones, but, at the same time, mucin extrusion was seen from the dilated duct through the papilla. Pancreatoduodenectomy was performed. Surgery and histology confirmed malignant IPMN with the typical image of chronic pancreatitis and intraductal stones in the vicinity. The patient is doing well 4 years after the surgery, without recurrence of the malignant disease, with changes of chronic pancreatitis in the pancreatic remnant. This paper discusses the possible relationships between the two entities and emphasizes the need of differential diagnosis.

    Full Text Available Chronic pain has been associated with impaired cognitive function. We examined cognitive performance in patients with severe chronic pancreatitis pain. We explored the following factors for their contribution to observed cognitive deficits: pain duration, comorbidity (depression, sleep disturbance, use of opioids, and premorbid alcohol abuse. The cognitive profiles of 16 patients with severe pain due to chronic pancreatitis were determined using an extensive neuropsychological test battery. Data from three cognitive domains (psychomotor performance, memory, executive functions were compared to data from healthy controls matched for age, gender and education. Multivariate multilevel analysis of the data showed decreased test scores in patients with chronic pancreatitis pain in different cognitive domains. Psychomotor performance and executive functions showed the most prominent decline. Interestingly, pain duration appeared to be the strongest predictor for observed cognitive decline. Depressive symptoms, sleep disturbance, opioid use and history of alcohol abuse provided additional explanations for the observed cognitive decline in some of the tests, but to a lesser extent than pain duration. The negative effect of pain duration on cognitive performance is compatible with the theory of neurodegenerative properties of chronic pain. Therefore, early and effective therapeutic interventions might reduce or prevent decline in cognitive performance, thereby improving outcomes and quality of life in these patients.

    A 29-year-old woman admitted for alcohol detoxification five years after a 90% distal pancreatectomy for chronic pancreatitis had abdominal pain similar to that associated with preoperative pancreatitis. Although her clinical course was consistent with recurrent pancreatitis, the serum amylase level remained normal, but the amylase creatinine clearance ratio became elevated and then returned to normal, paralleling her clinical course. The ACCR may be a useful laboratory method in diagnosing chronic recurrent pancreatitis in patients with decreased functional pancreatic tissue.

    2006-03-18

    This paper reviews the current literature on chronic pancreatitis (CP). Despite marked progress in diagnostic tools, predominately imaging methods, no consensus has been reached on the nomenclature of CP, ie diagnosis, classification, staging, pathomechanisms of pain and its optimal treatment. A major problem is that no single reliable diagnostic test exists for early-stage CP except histopathology (rarely available). This stage is characterised typically by recurrent acute pancreatitis +/- necrosis (eg pseudocysts). Acute pancreatitis is a well-defined condition caused in 80% of cases by gallstones or alcohol abuse. Alcoholic pancreatitis, in contrast to biliary pancreatitis, progresses to CP in the majority of patients. However, a definite CP-diagnosis is often delayed because progressive dysfunction and/or calcification, the clinical markers of CP, develop on average 5 years from disease onset. The progression rate is variable and depends on several factors eg aetiology, smoking, continued alcohol abuse. Repeated function testing eg by the faecal elastase test, is the best alternative for histology to monitor progression (or non-progression) of suspected (probable) to definite CP. The pathomechanism of pain in CP is multifactorial and data from different series are hardly comparable mainly because insufficient data of the various variables ie diagnosis, classification, staging of CP, pain pattern and presumptive pain cause, are provided. Pain in CP is rarely intractable except in the presence of cancer, opiate addiction or extra-pancreatic pain causes. Local complications like pseudocysts or obstructive cholestasis are the most common causes of severe persistent pain which can be relieved promptly by an appropriate drainage procedure. Notably, partial to complete pain relief is a common feature in 50-80% of patients with late-stage CP irrespective of surgery and about 50% of CP-patients never need surgery (or endoscopic intervention).

  17. Role of YAP and TAZ in pancreatic ductal adenocarcinoma and in stellate cells associated with cancer and chronic pancreatitis.

    Pancreatic ductal adenocarcinoma (PDAC) is characterized by a fibrotic and inflammatory microenvironment that is formed primarily by activated, myofibroblast-like, stellate cells. Although the stellate cells are thought to contribute to tumorigenesis, metastasis and drug resistance of PDAC, the signaling events involved in activation of the stellate cells are not well defined. Functioning as transcription co-factors, Yes-associated protein (YAP) and its homolog transcriptional co-activator with PDZ-binding motif (TAZ) modulate the expression of genes involved in various aspects of cellular functions, such as proliferation and mobility. Using human tissues we show that YAP and TAZ expression is restricted to the centroacinar and ductal cells of normal pancreas, but is elevated in cancer cells. In particular, YAP and TAZ are expressed at high levels in the activated stellate cells of both chronic pancreatitis and PDAC patients as well as in the islets of Langerhans in chronic pancreatitis tissues. Of note, YAP is up regulated in both acinar and ductal cells following induction of acute and chronic pancreatitis in mice. These findings indicate that YAP and TAZ may play a critical role in modulating pancreatic tissue regeneration, neoplastic transformation, and stellate cell functions in both PDAC and pancreatitis.

    In the present study, we described an easily reproducable experimental pancreatits model induced by biliopancreatic duct injection of ethyl alcohol. Seventy Wistar albino rats were divided equally into seven groups randomly: the control group (group 1), acute pancreatitis groups; induced by 20% ethanol (group 2), 48% ethanol (group 3), 80% ethanol (group 4), chronic pancreatitis groups; induced by 20% ethanol (group 5), 48% ethanol (group 6) and by 80% ethanol (group 7). Acute pancreatitis groups were sacrified on postoperative day 3, while the control group and chronic pancreatitis groups were killed on postoperative day 7. Histopathologic evaluation was done, and P acute pancreatitis (100%). Inflammatory infiltration of neutrophils and mononuclear cells, interstitial edema, and focal necrotic areas were seen in the pancreatic tissues. Similarly, all rats in group 6 developed chronic pancreatitis (100%). Interstitial fibrosis, lymphotic infiltration, ductal dilatation, acinar cell atrophy, periductal hyperplasia were seen in the pancreatic tissues. Mortality was seen only in group 7. The biliopancreatic ductal injection of 48% ethanol induced acute and chronic pancreatitis has 100% success rate.

    Bouwense Stefan A

    2012-11-01

    Full Text Available Abstract Background After an initial attack of biliary pancreatitis, cholecystectomy minimizes the risk of recurrent biliary pancreatitis and other gallstone-related complications. Guidelines advocate performing cholecystectomy within 2 to 4 weeks after discharge for mild biliary pancreatitis. During this waiting period, the patient is at risk of recurrent biliary events. In current clinical practice, surgeons usually postpone cholecystectomy for 6 weeks due to a perceived risk of a more difficult dissection in the early days following pancreatitis and for logistical reasons. We hypothesize that early laparoscopic cholecystectomy minimizes the risk of recurrent biliary pancreatitis or other complications of gallstone disease in patients with mild biliary pancreatitis without increasing the difficulty of dissection and the surgical complication rate compared with interval laparoscopic cholecystectomy. Methods/Design PONCHO is a randomized controlled, parallel-group, assessor-blinded, superiority multicenter trial. Patients are randomly allocated to undergo early laparoscopic cholecystectomy, within 72 hours after randomization, or interval laparoscopic cholecystectomy, 25 to 30 days after randomization. During a 30-month period, 266 patients will be enrolled from 18 hospitals of the Dutch Pancreatitis Study Group. The primary endpoint is a composite endpoint of mortality and acute re-admissions for biliary events (that is, recurrent biliary pancreatitis, acute cholecystitis, symptomatic/obstructive choledocholithiasis requiring endoscopic retrograde cholangiopancreaticography including cholangitis (with/without endoscopic sphincterotomy, and uncomplicated biliary colics occurring within 6 months following randomization. Secondary endpoints include the individual endpoints of the composite endpoint, surgical and other complications, technical difficulty of cholecystectomy and costs.

    2010-09-01

    Full Text Available Dear Sir, We have recently shown that patients with chronic pancreatitis and pancreatic exocrine insufficiency exhibit greater postprandial responses of the intestinal hormone glucagon-like peptide-2 (GLP-2 as compared to healthy control subjects [1]. GLP-2 is a 33-amino acid peptide hormone secreted by the endocrine L cells of the intestinal mucosa following meal ingestion [2]. It acts as a growth factor in the small intestine [3] and, in patients with functional short-bowel syndrome, GLP-2 has been shown to improve intestinal absorption [4]. Furthermore, GLP-2 seems to increase intestinal blood flow [5], including blood flow in the superior mesenteric artery of pigs [6] and humans [7]. Interestingly, our recent observation of increased postprandial GLP-2 responses in patients with chronic pancreatitis and pancreatic exocrine insufficiency correlated with increased postprandial blood flow in the superior mesenteric arteries of these patients [1]. However, the mechanisms behind the increased postprandial GLP-2 response in chronic pancreatitis patients with pancreatic exocrine insufficiency could only be speculated upon, with one explanation being that reduced assimilation of nutrients in the proximal part of the small intestine results in delivery of a larger nutrient load to the distal L cell-rich part of the small intestine. Reduced assimilation of nutrients in chronic pancreatitis patients with pancreatic exocrine insufficiency can be clinically modulated by the administration of pancreatic enzyme supplementation. In 2007, we reported that pancreatic enzyme supplementation in these patients resulted in increased postprandial secretion of GLP-2’s sister peptide, GLP-1, also released from intestinal L cells [8]. In order to investigate potential mechanisms behind exaggerated GLP-2 levels in chronic pancreatitis we evaluated the impact of pancreatic enzyme supplementation on postprandial GLP-2 responses in the chronic pancreatitis patients

    Anomalous pancreaticobiliary union (APBU) has varied presentations. We report the case of a 12-year-old female who presented with biliary peritonitis due to a perforation of the common bile duct due to impaction of a pancreatic calculus at the duodenal papilla. She had a long common-biliary channel and pancreas divisum with chronic calcific pancreatitis involving the pancreatic head and neck. To our knowledge, this is the first such reported case in the literature.

    Chronic pancreatitis (CP) and pancreatic adenocarcinoma (PDAC) are the most common diseases of the pancreas. Cachexia-weight loss exceeding 10% of stable body weight-is present in up to 80% of patients with PDAC. Because the mechanisms of cachexia are not well known, this provides a possibility to compare clinical courses of benign and malignant cachexia. In this study, 382 patients-242 with a PDAC stage UICC II/ 140 with CP-were documented regarding the prevalence of cachexia and its influence on perioperative morbidity and mortality with a special interest to postoperative weight gain and survival. Cachexia was present in 41.4% of CP and 31% of cancer patients. We could demonstrate more pronounced systemic effects of cachexia in patients with PDAC. Weight loss was faster in PDAC patients, the amount of weight loss did not differ significantly between the groups. Cachexia had a significant impact on survival and the postoperative course in patients with PDAC and tumor resection. The development of cachexia is faster in patients with a malignant disease and the systemic effects are more pronounced. Therefore, tumor cachexia should be considered as a different entity than cachexia in benign diseases.

    Chronic hepatitis C virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma. Combination therapy of pegylated interferon-alpha (PEG-IFN-α) and ribavirin (RBV) is a current standard treatment for chronic HCV infection in Korea, which has considerable adverse effects. Acute pancreatitis is a rare complication of PEG-IFN-α administration. We report a case of a 62-year-old female who experienced acute pancreatitis after 4 weeks of PEG-IFN-α-2a and RBV combination therapy for chronic HCV infection. The main cause of the acute pancreatitis in this case was probably PEG-IFN-α rather than RBV for several reasons. A few cases have been reported in which acute pancreatitis occurred during treatment with PEG-IFN-α-2b. This is the first report of acute pancreatitis associated with PEG-IFN-α-2a in Korea.

    Full Text Available GNMT: glycine N-methyltransferase; SAH: Sadenosylhomocysteine; SAM: S-adenosylmethionine Dear Sir, The comprehensive review by Braganza and Dormandy on micronutrient therapy for chronic pancreatitis included emphasis on the role of methyl group and thiol metabolism [1]. I am writing to expand on the comments expressed in the letter by Rajesh et al. [2] and the reply by Dr. Braganza [3] in the July issue of JOP. Journal of the Pancreas (Online. These have served to highlight the results reported by Girish et al. in which they suggest that a deficiency of methyl groups may be a factor in the development of pancreatitis [4]. In their letter, Rajesh et al. cite our paper showing that pancreatic secretion in rats is compromised in folate deficiency [2]. There is a close relationship between folate and methyl group metabolism. Folate is required for the de novo synthesis of methyl groups. The ratio of Sadenosylmethionine (SAM to S-adenosylhomocysteine (SAH is regulated by the enzyme glycine Nmethyltransferase (GNMT under the control of a specific form of folate [5]. GNMT is very abundant in the exocrine cells of the pancreas [6] and in a subsequent publication we showed that SAM plays an important role in the secretory process from pancreatic exocrine cells [7]. In that paper we provided evidence that SAM might be needed for carboxymethylation of G proteins that are needed in the process of exocytosis. It should also be noted that the process of exocytosis involves the fusion and regeneration of membranes that are generated in the Golgi and the rough endoplasmic reticulum [8]. Tissues that are actively involved in exocrine secretion may then have an increased requirement for synthesis of phosphatidylcholine, an important component of the plasma membrane. There are two pathways that are used for the synthesis of phosphatidylcholine. The major pathway in most tissues utilizes preformed choline reacting with cytidine triphosphate to eventually form

    Chronic pancreatitis remains a debilitating disease with few definitive options for treatment. The purpose of this study was to evaluate the benefit of pancreaticoduodenectomy in the treatment of chronic pancreatitis. The results were evaluated by standard descriptive statistics. In a retrospective study, we reviewed the patients at a single institution undergoing pancreaticoduodenectomy between 1994 and 1997 for complications of chronic pancreatitis. Patients were evaluated for preoperative indication for surgery and perioperative morbidity and mortality, as well as long-term results. Thirty-two patients underwent pancreaticoduodenectomy for chronic pancreatitis; 56 per cent (18) underwent pylorus-preserving and 44 per cent (14) underwent classic pancreaticoduodenectomy. The mean age of these patients was 56+/-14.7 years (range, 23-79). All patients underwent preoperative CT scan and endoscopic retrograde cholangiopancreatography. The preoperative indication for surgery in 81 per cent (26) of these patients was intractable pain in the setting of a nondilated pancreatic duct. The other 19 per cent were treated for biliary/pancreatic duct stricture and pancreatic head fibrosis (mass suspicious of malignancy). Fifty-three per cent of the patients had a history of previous abdominal surgery. There were no perioperative deaths. The mean postoperative stay was 12.2+/-7.4 days. The postoperative morbidity rate was 31 per cent (10), consisting of 25 per cent with delayed gastric emptying, 3 per cent with pneumonia, and 3 per cent with wound infections. There was no occurrence of pancreatic fistulas. With a mean follow-up of 40 months (range, 10-52 months), 85 per cent reported a significant improvement in pain with 71 per cent being pain free and not requiring narcotics. Twenty per cent developed new-onset diabetes. The overall event survival rate at 5 years was 97 per cent. Thus, in a selected group of patients with severe chronic pancreatitis, resection of the head of

The association with valproic acid was not recognized, and the child continued to take the drug. The patient eventually developed steatorrhea and weight loss that improved with pancreatic enzyme replacement. Radiological evaluation showed an atrophic pancreas. Without evidence of other etiological factors, valproic acid by itself appeared to be the cause of chronic pancreatitis with exocrine pancreatic insufficiency in this patient.

    Pancreatic secretory trypsin inhibitor (PSTI) is a potent natural inhibitor of trypsin. We proposed the hypothesis that, if the function of the PSTI is impaired by its genetic mutation, trypsin may easily promote autodigestion causing pancreatitis and we performed a mutational analysis of the PSTI gene in patients with pancreatitis. Two exonic mutations (N34S and R67C) were thought to be associated with a predisposition to pancreatitis. The N34S mutation was co-segregated with two intronic mu...

Objective To undertake a prospective nationwide study of the risk factors and clinical profile of chronic pancreatitis. Setting Thirty-two major centers from different regions of India contributed data on 1,086 patients to a common online website (www.ipans.org. Main outcome measures Risk factors, clinical features complications and treatment of chronic pancreatitis. Results Of the 1,086 subjects, complete data on risk factors were available for 1,033 subjects. Idiopathic pancreatitis was the most common form of pancreatitis (n=622; 60.2% and alcoholic chronic pancreatitis accounted for about a third of the cases (n=400; 38.7%; the rest (n=11; 1.1% had rare risk factors. Smoking and cassava intake were documented in 292 (28.3% and 189 (18.3% subjects, respectively. Using well-defined criteria, only 39 (3.8%cases could be labeled as ‘tropical pancreatitis’. Pain occurred in 971 patients (94.0%. Four hundred and eighteen (40.5% subjects had diabetes mellitus. Of alcohol consumers, alcoholism and female gender were independent risk factors for diabetes in subjects with chronic pancreatitis (OR=1.48, P=0.003; and OR=1.75, P<0.001, respectively.

    Chronic pancreatitis is an inflammatory disease of the pancreas, which is characterized by destruction of pancreatic secretory parenchyma and progressing exocrine and endocrine insufficiency. Usually these patients have complications as cardiovascular, renal, respiratory and liver failure, and various gastric dysfunctions. The data of clinical observations do not reveal fully the functional state of the stomach and liver in chronic pancreatitis also remains an open question about the quality of the gastric juices and bile by this pathology. Therefore our aim was to investigate the secretory functions of the stomach and liver features in rats at the experimental chronic pancreatitis. This pathology modeled using L-arginine. Basal gastric secretion was investigated in chronic experiment by aspiration method for 10th and 63rd days, and pancreas and liver--in acute experiments at 13th and 68th days after the last administration of L-arginine. It was established that the character of the secretory response of the digestive tract depends on the duration of the pathology course. On the 10th day the functional state of the gastric secretory glands in rats with chronic pancreatitis characterized by twice increase of gastric acid production but decrease the level of hexosamines on 23.8% (P chronic pancreatitis particularly the digestive system functioning features at this pathology. These data could be considered in the appointment of treatment to avoid complications.

    Full Text Available Abstract Background Chronic pancreatitis is characterized by progressive fibrosis, pain and loss of exocrine and endocrine functions. The long-standing chronic pancreatitis and its associated pancreatic fibrosis are the most common pathogenic events involved in human pancreatic carcinogenesis, but the therapeutic strategies to chronic pancreatitis and the chemoprevention of pancreatic carcinogenesis are very limited. Methods We investigated the effect of sulindac, a non-steroidal anti-inflammatory drug (NSAID, on inhibition of chronic pancreatitis in a caerulein induced chronic pancreatitis mouse model. Results Sulindac significantly reduced the severity of chronic pancreatitis including the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The protein expression of phosphorylation of MEK/ERK was inhibited in the chronic pancreatic tissues by sulindac treatment as measured by Western blot assay. The levels of inflammatory cytokines including TNF-α and MCP-1 were also significantly decreased with sulindac treatment, as well as the expression of TGF-β, PDGF-β, SHH and Gli in the chronic pancreatic tissue detected by qPCR assay and confirmed by western blot assay. The activation of pancreatic satellet cells was also inhibited by sulindac as measured by the activity of α-smooth muscle actin (α-SMA in the pancreatic tissue of chronic pancreatitis. Conclusions Sulindac is a promising reagent for the treatment of chronic pancreatitis via inhibition of inflammatory cell infiltration and stromal fibrosis, the inhibitory effect of sulindac on chronic pancreatitis may through targeting the activation ERK/MAPK signaling pathway.

    AIM: To examine surgical specimens of pancreas with either chronic pancreatitis or pancreatic cancer in order to study whether ductal hyperplasia and dysplasia in pancreas represent precursor lesions for pancreatic cancer.METHODS: We examined expression of Ki-67, CEA,p53, and K-ras, in the surgical specimens of pancreas with adenocarcinomas (n = 11) and chronic pancreatitis (n = 12). Cellular proliferation was assessed by Ki-67proliferation index using the proliferation marker Ki-67.In specimens with pancreas cancer, we divided pancreas epithelium into normal (n=7), ductal hyperplasia (n=3), dysplasia (n=4), and cancerous lesion (n=11) after hematoxylin and eosin staining, Ki-67, and CEA immunohistochemical staining. In cases with chronic pancreatitis, the specimen was pathologically examined as in cases with pancreas cancer, and they were also determined as normal (n=10), ductal hyperplasia (n=4), or dysplasia (n= 5). p53 and K-ras expression were also studied by immunohistochemical staining.RESULTS: In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductalhyperplasia, 13.47±4.02 in dysplasia and 37.03±10.05in cancer tissue, respectively. Overall, p53 was positive in normal ducts, ductal hyperplasia, dysplasia, and carcinoma cells in 0 of 14 (0%), 0 of 7 (0%), 7 of 9 (78%),and 10 of 11 (91%), respectively, and K-ras was positive in 0 of 8 (0%), 1 of 3 (33%), 4 of 6 (67%), 4 of 5 (80%),respectively.CONCLUSION: Our results favorably support the hypothesis that ductal hyperplasia and dysplasia of the pancreas might be precursor lesions for pancreas cancer.Further evaluation of oncogenes by the molecular study is needed.

    Background Surgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP).Two major strategies exist:duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD).Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however,the long-term effects have not been thoroughly investigated.We analyzed the long-term outcomes of DPPHR and PD,over follow-up times of at least 1 year,to determine the optimal surgical treatment for CP.Methods We systemically reviewed all CP surgical treatment reports,and only included randomized controlled trials (RCT) comparing DPPHR and PD,excluding unqualified studies using several pre-specified criteria.When multiple publications of a single trial were found,the most comprehensive current data were selected.Characteristics of the study populations and long-term postoperative outcome parameters were collected.The quality of the studies and data was analyzed using RevMan 4.2 software.Results Five trials were qualified for meta-analysis,with 261 participants in total (114 in the DPPHR group and 147 in the PD group).There were no significant differences in the age,gender,or indications for surgery of each group.At the mean of 5.7-year (1-14 years) follow-up examination,DPPHR and PD resulted in equally effective pain relief,exocrine and endocrine function,and similar mortality rates (P >0.05); however,DPPHR patients had improved global quality of life and weight gain,and reduced diarrhea and fatigue (P <0.05).Conclusion DPPHR and PD result in equal pain relief,mortality,and pancreatic function; however,DPPHR provides superior long-term outcomes.

    Full Text Available Abdominal pain in chronic pancreatitis patients is mostly induced by a fatty diet, overeating or alcohol consumption [1, 2, 3]. Chronic pancreatitis patients who experience repeated pain episodes often require inpatient management which may affect the patients’ social life and decrease their quality of life. The guidelines of the American Gastroenterological Association recommend a low-fat diet, non-narcotic analgesics and no alcohol consumption for pain management in chronic pancreatitis [4]. We herein report two cases of calcified chronic pancreatitis with repeated pain episodes which could be alleviated, at home, by the oral administration of a low-fat elemental diet used for enteral nutrition [5, 6] at the convalescent stage of acute pancreatitis. In Case #1, the patient was a 38-year-old woman who was diagnosed with alcoholic calcified chronic pancreatitis 8 years ago. She experienced repeated pain episodes which had persisted for the previous three years. The pain was judged untreatable by conservative medical therapy and, therefore, she had undergone a celiac plexus block and pancreaticojejunostomy. Her condition had thereafter improved and she had refrained from drinking for a while. However, she started to experience the pain after resuming drinking two years previously. Abdominal CT revealed a relatively large pancreatic stone in the main pancreatic duct in the pancreatic head (Figure 1a as well as small diffuse stones in the pancreas (Figure 1b. Although she was advised to stay in the hospital, she refused to be hospitalized because she thought that she would lose her job. Therefore, oral administration of an elemental diet was started at home.

    Full Text Available Some patients with autoimmune pancreatitis (AIP form pancreatic stones suggestive of transformation into chronic pancreatitis (CP. The present study examined the underlying risk factors and mechanism of AIP progression to confirmed CP. We compared the clinical and laboratory parameters of subjects who progressed to confirmed CP with those of the subjucts who did not in a cohort of 73 type 1 AIP patients. A total of 16 (22% AIP patients progressed to CP. Univariate analysis revealed that relapse was significantly more frequent in the progression group, and multivariate analysis indicated that pancreatic head swelling (OR 12.7, P=0.023 and nonnarrowing of the main pancreatic duct in the pancreatic body (OR 12.6, P=0.001 were significant independent risk factors for progression to CP. Kaplan-Meier testing showed that the progression rate to CP was approximately 10% at 3 years and 30% at 10 years in total AIP patients and 30% at 3 years and 60% at 10 years in subjects with both risk factors. AIP with pancreatic head swelling and a history of relapse may cause pancreatic juice stagnation and nonnarrowing of the main pancreatic duct in the pancreatic body, which can progress to advanced stage chronic pancreatitis.

    Full Text Available EUS is highly accurate in the diagnosis of chronic pancreatitis. Pancreatic calcifications or five or more endosonographic criteria are consistent with chronic pancreatitis. Less than three criteria essentially rules out chronic pancreatitis. Three or four criteria are the best overall cutoffs. The number of criteria is used to estimate the likelihood of pancreatitis (i.e. low/medium/high, and is not recommended to stage the severity (i.e. mild/moderate/severe of disease. Obtaining histology by FNA is not recommended in all patients with chronic pancreatitis changes. EUS is useful in distinguishing inflammatory from malignant masses in the pancreas. FNA is often not required as the EUS appearance of inflammatory changes alone or bulkiness without any perceptible mass has good negative predictive value. In indeterminate masses, FNA for cytology is recommended. Follow-up imaging after one to two months can be performed to catch the rare EUS false-negatives, and confirm resolution or stability of inflammatory masses.

    Full Text Available "nBackground: Chronic pancreatitis and perivasculitis is the most common etiology of splenic vein thrombosis (SVT. Reported in up to 45% of patients with chronic pancreatitis, SVT may also be seen in patients with acute pancreatitis and pancreatic adenocarcinoma. It causes a localized portal hypertension called sinistral portal hypertension. Unlike those with generalized portal hypertension, patients with sinistral portal hypertension are asymptomatic and have normal liver function. Upper gastrointestinal bleeding from gastric varices is a life threatening complication of SVT.

    2013-05-01

    Full Text Available Chronic pancreatitis is a progressive inflammatory disease resulting from repeated episodes of acute pancreatitis that impair exocrine function and eventually produce endocrine insufficiency. Some causes of chronic pancreatitis appear to be associated with alterations in the serine&#8211;protease inhibitor, Kazal type 1 (SPINK1 , cationic trypsinogen (PRSS1 , and cystic fibrosis&#8211;transmembrane conductance regulator (CFTR genes, or with structural disorders in the pancreaticobiliary ductal system, such as pancreatic divisum or anomalous pancreaticobiliary ductal union (APBDU. However, it is unusual to observe both genetic alteration and structural anomaly. Here, we report 2 cases with both APBDU and a mutation in the SPINK1 genes, and we discuss the implications of these findings in clinical practice.

    Chronic pancreatitis is a fairly common condition with pain being the major symptom, and longitudinal pancreaticojejunostomy (LPJ) is performed for symptomatic relief. The aim of the study is to assess relief of pain post-LPJ for chronic pancreatitis and to evaluate the factors influencing relief of symptoms. A prospective observational non-interventional study enrolling 28 patients. This study involved a questionnaire studying various risk factors and pain related to chronic pancreatitis, pancreaticojejunostomy, and postoperative assessment of pain relief at 1 and 6 months from surgery. Pain was assessed using Visual analogue scale (VAS). In chronic pancreatitis, there is a significant relief in symptoms of pain post-LPJ; the degree of relief was less in the alcoholics vs non-alcoholics (p = 0.09) and smokers. There was also reduction in analgesic requirement and frequency of acute attacks of pain. Fifty-seven percent of patients had a complete remission of their pain after LPJ for CP. In chronic pancreatitis, there is a significant relief in symptoms of pain post-LPJ, although the degree of relief is less in the alcoholics and smokers.

  13. Mass lesions in chronic pancreatitis: benign or malignant? An "evidence-based practice" approach.

    2012-02-01

    The diagnosis of a pancreatic mass lesion in the presence of chronic pancreatitis can be extremely challenging. At the same time, a high level of certainty about the diagnosis is necessary for appropriate management planning. The aim of this study was to establish current best evidence about which imaging methods reliably differentiate a benign from a malignant lesion, and show how that evidence is best applied. A diagnostic algorithm based on Bayesian analysis is proposed.

    Pancreatic and salivary amylase/creatinine clearance ratios in patients with various degrees of renal impairment were compared with those obtained for control subjects. In chronic renal insufficiency (mean GFR 30 ml/min +/- 15 SD; n = 13) the clearance ratios for pancreatic (mean 3.5 +/- 1.85 SD) and salivary (mean 2.3 +/- 1.3 SD) amylase were significantly higher (P less than 0.05) than those in controls. Corresponding control values (n = 26) were 2.64 +/- 0.86 (pancreatic) and 1.64 +/- 0.95 (salivary). Three patients showed values above the normal limit. In the diabetic group (mean GFR 41 ml/min +/- 22 SD; n = 10) salivary amylase/creatinine clearance ratios (mean 2.36 +/- 1.55 SD) were significantly higher than in controls (P less than 0.05). Three patients showed raised values. Pancreatic amylase clearance was raised in only one of these patients. Three patients with terminal disease (mean GFR 10 ml/min) showed markedly raised (two- to threefold) clearance ratios for both salivary and pancreatic amylase. Of a total of 26 patients, eight had increased total amylase/creatinine clearance ratios. Pancreatic amylase/creatinine clearance was increased in seven patients, while nine patients showed raised salivary amylase/creatinine ratios. Patients with raised clearance ratios did not have clinical evidence of pancreatitis. We suggest that, in the presence of impaired renal function, a high amylase/creatinine clearance ratio need not be indicative of pancreatic disease.

    The article presents data on peculiarities of chronic pancreatitis course in railway transport workers (engine operators, engine operator assistants, dispatchers) with anxious depressive disorders. Pain and dyspepsia in patients with affective disorders appeared to be constant and more intense than in the patients without concomitant anxious depression. Psychophysiologic tests in 83% of patients with comorbid conditions revealed significant psychomotor dullness manifested in reliable lower speed of visual motor reactions. Pharmacologic correction via anxiolytics (Adaptol, Afobasol) combined with standard therapy for chronic pancreatitis exacerbation enabled to improve clinical symptoms, but Adaptol appeared to slow simple visual motor reactions, therefore has to be ruled out in engine operators. Pharmacotherapy of chronic pancreatitis, that included Afobasol in addition to standard treatment, promoted reliable improvement of occupationally important psychophysiologic functions. This study received a patent.

    Chronic pancreatitis (CP) is a common disease in the department of gastroenterology, with the main symptoms of exocrine and/or endocrine insufficiency and abdominal pain. The pathogenic mechanism of CP is still not fully clarified and the aims of treatment now are to relieve symptoms. In this study, we attempted to find a connection between interleukin-1β (IL-1β) and interleukin-1 receptor antagonist (IL-1Ra) in trinitrobenzene sulfonic acid (TNBS)-induced chronic pancreatitis, and then the therapeutic effect of recombinant IL-1Ra was also detected in the CP model. Chronic pancreatitis was induced by intraductal infusion of TNBS in SD rats followed by a consecutive administration of rIL-1Ra, and the histological changes and collagen content in the pancreas were measured, as well as the abdominal hypersensitivity. We found that rhIL-1Ra could attenuate the severity of chronic pancreatic injury, modulate the extracellular matrix secretion, focal proliferation and apoptosis, and cellular immunity in TNBS-induced CP. Interestingly, rIL-1Ra could also block the pancreatitis-induced referred abdominal hypersensitivity. In conclusion, IL-1Ra may play a protective role in CP and rIL-1Ra would be a potential therapeutic target for the treatment of CP, while its possible mechanisms and clinical usage still need further investigation.

    AIM: To investigate the usefulness of secretin injection MRCP for the diagnosis of mild chronic pancreatitis. METHODS: Sixteen patients having mild chronic pancreatitis according to the Cambridge classification and 12 control subjects with no abnormal findings on the pancreatogram were examined for the diagnostic accuracy of secretin injection-MRCP regarding abnormal branch pancreatic ducts associated with mild chronic pancreatitis (Cambridge Classification), using endoscopic retrograde cholangiopancreatography (ERCP) for comparison. RESULTS: The sensitivity and specificity for abnormal branch pancreatic ducts determined by two reviewers were respectively 55%-63% and 75%-83% in the head, 57%-64% and 82%-83% in the body, and 44%-44%and 72%-76% in the tail of the pancreas. The sensitivity and specificity for mild chronic pancreatitis were 56%-63% and 92%-92%, respectively. Interobserver abnormal branch pancreatic duct and of mild chronic pancreatitis was good to excellent. CONCLUSION: Secretin injection-MRCP might be useful for the diagnosis of mild chronic pancreatitis.

    Full Text Available Context Acute and chronic pancreatitis may present with pseudocysts in atypical locations. Activated pancreatic enzymes track along anatomic fascial planes causing digestion of the surrounding tissues and resulting in distant pseudocysts. Pseudocysts at atypical locations pose significant diagnostic as well as therapeutic challenges. Case report We report an unusual presentation of a pancreatic pseudocyst in a young male who presented with a left perinephric abscess. Percutaneous drainage was not successful in resolving the abscess and he was subsequently diagnosed as having chronic pancreatitis together with a left perinephric abscess. Needle knife sphincterotomy of the ampulla of Vater resulted in the gradual resolution of the abscess. Conclusion We report a rare presentation of chronic pancreatitis with a perinephric abscess and its non-surgical management. This case report indicates that any patient presenting with a perinephric abscess of unknown etiology not responding to conventional treatment modalities should be investigated for underlying pancreatitis.

    Cystic dystrophy of the duodenal wall is a rare form of the disease which was described in 1970 by French authors who reported the presence of focal pancreatic disease localized in an area comprising the C-loop of the duodenum and the head of the pancreas. German authors have defined this area as a "groove". We report our recent experience on cystic dystrophy of the paraduodenal space and systematically review the data in the literature regarding the alterations of this space. A MEDLINE search of papers published between 1966 and 2010 was carried out and 59 papers were considered for the present study; there were 19 cohort studies and 40 case reports. The majority of patients having groove pancreatitis were middle aged. Mean age was significantly higher in patients having groove carcinoma. The diagnosis of cystic dystrophy of the duodenal wall can now be assessed by multidetector computer tomography, magnetic resonance imaging and endoscopic ultrasonography. These latter two techniques may also add more information on the involvement of the remaining pancreatic gland not involved by the duodenal malformation and they may help in differentiating "groove pancreatitis" from "groove adenocarcinoma". In conclusion, chronic pancreatitis involving the entire pancreatic gland was present in half of the patients with cystic dystrophy of the duodenal wall and, in the majority of them, the pancreatitis had calcifications.

    The aim of this study was to establish the correlation between the occurrence of Q705K and F359L polymorphisms in patients diagnosed with pancreatic diseases and periodontal conditions of various degrees of severity. The above-mentioned genetic markers were assessed in patients with pancreatic cancer (n = 18) and chronic pancreatitis (n = 39) as well as in a healthy control group (n = 115). The established inclusion criteria were the following: Caucasian descent, non-smoking, and age range 20-80, with different levels of periodontitis activity according to S. Offenbacher's scale. The genotyping reactions were performed by means of an RT-PCR with the use of TaqMan(®) genotyping assay. Results of the study revealed that the state of periodontium was significantly worse in patients with chronic pancreatitis. The Q705K and F359L polymorphisms were associated with more advanced cases of periodontitis measured by clinical attachment level, whereas the Q705K was associated with intensified bleeding index. Furthermore, the F359L single-nucleotide polymorphism was significantly higher in the group with chronic pancreatitis (p periodontitis, pancreatic cancer, and chronic pancreatitis. These findings might constitute the basis for a new diagnostic and therapeutic approach.

    Chronic pancreatitis (CP) is a devastating disease characterized by persistent and uncontrolled abdominal pain. Our lack of understanding is partially due to the lack of experimental models that mimic the human disease and also to the lack of validated behavioral measures of visceral pain. The ligand-gated cation channel transient receptor potential ankyrin 1 (TRPA1) mediates inflammation and pain in early experimental pancreatitis. It is unknown if TRPA1 causes fibrosis and sustained pancreatic pain. We induced CP by injecting the chemical agent trinitrobenzene sulfonic acid (TNBS), which causes severe acute pancreatitis, into the pancreatic duct of C57BL/6 trpa1(+/+) and trpa1(-/-) mice. Chronic inflammatory changes and pain behaviors were assessed after 2-3 wk. TNBS injection caused marked pancreatic fibrosis with increased collagen-staining intensity, atrophy, fatty replacement, monocyte infiltration, and pancreatic stellate cell activation, and these changes were reflected by increased histological damage scores. TNBS-injected animals showed mechanical hypersensitivity during von Frey filament probing of the abdomen, decreased daily voluntary wheel-running activity, and increased immobility scores during open-field testing. Pancreatic TNBS also reduced the threshold to hindpaw withdrawal to von Frey filament probing, suggesting central sensitization. Inflammatory changes and pain indexes were significantly reduced in trpa1(-/-) mice. In conclusion, we have characterized in mice a model of CP that resembles the human condition, with marked histological changes and behavioral measures of pain. We have demonstrated, using novel and objective pain measurements, that TRPA1 mediates inflammation and visceral hypersensitivity in CP and could be a therapeutic target for the treatment of sustained inflammatory abdominal pain.

  10. From Acute to Chronic Pancreatitis: The Role of Mutations in the Pancreatic Secretory Trypsin Inhibitor Gene

    Directory of Open Access Journals (Sweden)

    Hirota M

    2003-03-01

    Full Text Available Pancreatic secretory trypsin inhibitor (PSTI is a potent natural inhibitor of trypsin. We proposed the hypothesis that, if the function of the PSTI is impaired by its genetic mutation, trypsin may easily promote autodigestion causing pancreatitis and we performed a mutational analysis of the PSTI gene in patients with pancreatitis. Two exonic mutations (N34S and R67C were thought to be associated with a predisposition to pancreatitis. The N34S mutation was co-segregated with two intronic mutations, IVS1-37T>C and IVS3-69insTTTT. Although we analyzed the function of the recombinant N34S protein, we could not demonstrate the loss of function of this protein. Intronic mutations, rather than N34S itself (IVS1-37T>C + N34S + IVS3-69insTTTT complex, may be associated with the decreased function of the PSTI. Alternatively, increased digestion of N34S in vivo may be applicable. As for R67C, the conformational alteration of the protein by forming intra-molecular or inter-molecular disulfide bonds with 67Cys was strongly suggested. These results, along with the brand-new findings in PSTI knockout mice, suggest that the genetic mutation of the PSTI is one of the important mechanisms for predisposition to pancreatitis by lowering the trypsin inhibitory function.

    2017-02-27

    We report the case of a patient with acute exacerbation of chronic pancreatitis and he suffered an atraumatic splenic rupture. Splenic rupture not associated with trauma is a rare entity that can occurs in normal spleen (spontaneous) or damaged spleen (pathological). This entity may be associated with local inflammatory processes, such as pancreatitis. Ultrasound is a non-invasive technique which is used in unstable patients. CT is useful for making a diagnosis of extension in patients with hemodynamic stability. Atraumatic splenic rupture as a complication of chronic pancreatitis is an unusual disease that requires a high index of suspicion which allows us an early diagnosis because it is a treatable entity that compromises the patient's life.

    Alcohol abuse increases the risk for pancreatitis. The pattern of alcohol drinking may impact its effect. We tested a hypothesis that chronic ethanol consumption in combination with binge exposure imposes more severe damage to the pancreas. C57BL/6 mice were divided into four groups: control, chronic ethanol exposure, binge ethanol exposure and chronic plus binge ethanol exposure. For the control group, mice were fed with a liquid diet for two weeks. For the chronic ethanol exposure group, mice were fed with a liquid diet containing 5% ethanol for two weeks. In the binge ethanol exposure group, mice were treated with ethanol by gavage (5g/kg, 25% ethanol w/v) daily for 3days. For the chronic plus binge exposure group, mice were fed with a liquid diet containing 5% ethanol for two weeks and exposed to ethanol by gavage during the last 3days. Chronic and binge exposure alone caused minimal pancreatic injury. However, chronic plus binge ethanol exposure induced significant apoptotic cell death. Chronic plus binge ethanol exposure altered the levels of alpha-amylase, glucose and insulin. Chronic plus binge ethanol exposure caused pancreatic inflammation which was shown by the macrophages infiltration and the increase of cytokines and chemokines. Chronic plus binge ethanol exposure increased the expression of ADH1 and CYP2E1. It also induced endoplasmic reticulum stress which was demonstrated by the unfolded protein response. In addition, chronic plus binge ethanol exposure increased protein oxidation and lipid peroxidation, indicating oxidative stress. Therefore, chronic plus binge ethanol exposure is more detrimental to the pancreas.

    Full Text Available Alcohol abuse is one of the most common risk factor for chronic pancreatitis, but the underlying pathophysiological mechanisms remain unclear. The aim of this study was to identify genes that contribute to susceptibility or resistance for alcoholic chronic pancreatitis by screening the whole genome. Sixty-five patients with alcoholic chronic pancreatitis (63 men and 2 women, mean age 55.2 years and 99 healthy Japanese controls were enrolled in this study. This was an association study using 400 polymorphic microsatellite markers with an average spacing of 10.8 cM distributed throughout the whole genome. This search revealed 10 candidate susceptibility regions and 5 candidate resistant regions throughout the genome. No specific microsatellite markers were detected in association with previously reported susceptibility genes for chronic pancreatitis, such as PRSS1, PRSS2, CTRC, SPINK1, CFTR, ALDH2, and CYP2E1. Among the statistically significant markers, D15S1007 on chromosome 15q14 showed strong evidence for disease susceptibility (70.8% vs. 35.1%, Pc = 0.0001. Within 500 kb of D15S1007, several genes were candidate genes for susceptibility, including FMN1, DKFZP686C2281, LOC440268, RYR3, and AVEN, This study identified 10 candidate susceptibility and 5 candidate resistant regions that may contain genes involved in ACP pathogenesis.

    2006-01-01

    Full Text Available Due to its therapeutic properties, endoscopy can influence the quality of life (QoL of patients suffering from chronic pancreatitis (CP. Pancreatic ductal decompression represents the most frequent endoscopic procedure in patients with painful CP and it can be considered as a first-line treatment for improving the clinical condition. Endoscopy can limit surgery to unsuccessful or relapse cases. The best candidates for endoscopic treatment are patients with cephalic obstruction of the main pancreatic duct (MPD by stone(s and/or stricture(s with upstream dilation (type IV or, respectively, type V according to the Brussels or the Cambridge ERCP classification [1, 2]. These patients had pain as a consequence of an elevated intraductal pressure. Combined techniques are usually employed to remove stones and/or to dilate a stenosis, such as a pancreatic sphincterotomy, mechanic lithotripsy, extracorporeal shockwave lithotripsy (ESWL and pancreatic stent(s. Endoscopy has the potential of improving the QoL in patients with CP since it can decrease or entirely eliminate pancreatic pain and MPD dilation, two variables capable of impairing physical and mental domains [3, 4, 5]. In the Pezzilli et al. study [3], pain was the unique clinical variable able to significantly impair all physical and mental domains in a SF-36 questionnaire administered to 190 consecutive patients with proven CP.

    Full Text Available CONTEXT: Main pancreatic duct stones may contribute to pain in chronic pancreatitis. Extracorporeal shock wave lithotripsy (ESWL has been used alone or in combination with endoscopic therapy for fragmentation of stones. Published studies have shown mixed efficacy due to small sample size. OBJECTIVE: Systematic analysis of all published data evaluating ESWL with or without endoscopic therapy in pancreatic duct clearance and symptom relief. METHODS: Two investigators independently reviewed the computer databases. 31 potential studies were identified. Only studies using ESWL with or without endoscopic therapy were included. Completeness of the search was confirmed by an expert. Studies were independently coded by two investigators and differences rectified by mutual consent. MAIN OUTCOME MEASURES: Pain at follow-up and duct clearance. RESULTS: Seventeen studies published between 1989 and 2002 were included. Sixteen had a measure of pain at follow-up and duct clearance. All studies were case series with a total of 588 subjects, and included varying number of subjects undergoing endoscopic pancreatic sphincterotomy and stone extraction. The mean effect size (weighted correlation coefficient for pain was 0.6215 and for duct clearance was 0.7432; thus indicating a large effect. All studies showed homogeneity suggesting similar effect size irrespective of the combinations of therapy. CONCLUSIONS: ESWL is effective in clearance of stones from the pancreatic duct and in relief of pain. Published studies showed homogeneity of the effect size of ESWL both in pancreatic duct clearance and relief of pain.

    Chronic pancreatitis (CP), a progressive inflammatory disease where acini are destroyed and replaced by fibrous tissue, increases the risk for pancreatic cancer. Risk factors include alcohol, smoking, and obesity. The effects of these risk factors are exacerbated in patients with mutations in genes that predispose to CP. The different environmental and genetic factors produce the same clinical phenotype; once CP develops, disease course is the same regardless of etiology. Critical questions still need to be answered to understand what modifies predisposition to develop CP in persons exposed to risk factors. We postulate that risk factors modulate endogenous pathways, with parathyroid hormone-related protein (PTHrP) signaling being one such pathway. In support, PTHrP levels are elevated in mice treated with alcohol, and in mouse models of cerulein- and pancreatic duct ligation-induced CP. Disrupting the Pthrp gene in acinar cells exerts protective effects (decreased edema, histological damage, amylase and cytokine release, and fibrosis) in these CP models. PTHrP levels are elevated in human CP. Currently, CP care lacks specific pharmacological interventions. Targeting PTHrP signaling may present a novel therapeutic strategy that inhibits pancreatic inflammation and fibrosis, especially since the risk of developing pancreatic cancer is strongly associated with duration of chronic inflammation.

    Visceral afferents expressing transient receptor potential (TRP) channels TRPV1 and TRPA1 are thought to be required for neurogenic inflammation and development of inflammatory hyperalgesia. Using a mouse model of chronic pancreatitis (CP) produced by repeated episodes (twice weekly) of caerulein-induced AP (AP), we studied the involvement of these TRP channels in pancreatic inflammation and pain-related behaviors. Antagonists of the two TRP channels were administered at different times to block the neurogenic component of AP. Six bouts of AP (over 3 wks) increased pancreatic inflammation and pain-related behaviors, produced fibrosis and sprouting of pancreatic nerve fibers, and increased TRPV1 and TRPA1 gene transcripts and a nociceptive marker, pERK, in pancreas afferent somata. Treatment with TRP antagonists, when initiated before week 3, decreased pancreatic inflammation and pain-related behaviors and also blocked the development of histopathological changes in the pancreas and upregulation of TRPV1, TRPA1, and pERK in pancreatic afferents. Continued treatment with TRP antagonists blocked the development of CP and pain behaviors even when mice were challenged with seven more weeks of twice weekly caerulein. When started after week 3, however, treatment with TRP antagonists was ineffective in blocking the transition from AP to CP and the emergence of pain behaviors. These results suggest: (1) an important role for neurogenic inflammation in pancreatitis and pain-related behaviors, (2) that there is a transition from AP to CP, after which TRP channel antagonism is ineffective, and thus (3) that early intervention with TRP channel antagonists may attenuate the transition to and development of CP effectively.

    2004-11-01

    Full Text Available CONTEXT: Alterations of the renin-angiotensin system have been implicated in the pathogenesis of various diseases. The angiotensin converting enzyme is a key enzyme in the renin-angiotensin system. A deletion polymorphism of a 287-bp fragment of intron 16 of the angiotensin converting enzyme gene allele results in higher levels of circulating enzyme. ACE deletion genotype has been linked to heart diseases, sarcoidosis and liver fibrosis. The pancreatic renin-angiotensin system plays a role in the development of pancreatic fibrosis and ACE inhibitors decrease pancreatic fibrosis in experimental models. OBJECTIVES: We investigated the frequency of the ACE gene insertion/deletion polymorphism in chronic pancreatitis patients and controls. PATIENTS: Subjects with familial pancreatitis (n=51, sporadic chronic pancreatitis (n=104, and healthy controls (n=163 were evaluated. MAIN OUTCOME MEASURE: The presence of ACE insertion/deletion polymorphism. RESULTS: The frequency of the ACE gene deletion allele was similar in familial pancreatitis (49.0% sporadic pancreatitis (51.0% and controls (55.8%. Furthermore, there was no significant difference in clinical features between patients with ACE-insertion or insertion/deletion genotypes vs. patients with ACE-deletion genotype. CONCLUSION: We conclude that the ACE deletion genotype does not make a significant contribution to the pathogenesis and the progression of chronic pancreatitis.

    The most important congenital anomalies include pancreas divisum, annular pancreas and ectopic pancreas. Patients with pancreas divisum may be more susceptible to acute or chronic pancreatitis and patients with an annular pancreas may develop duodenal stenosis. In pancreas divisum the key finding is the visualization of the main duct draining into the duodenum via the small papilla, separated from the common bile duct. Annular pancreas may show as a well defined ring of pancreatic tissue that encircles the duodenum. Ectopic pancreas is usually asymptomatic but may give rise to abdominal complaints and may be confused with submucosal tumors. Acute pancreatitis is classified as mild or severe. In mild forms ultrasound is the imaging modality of choice whereas in severe forms with extensive pancreatic and peripancreatic necroses computed tomography is the favored method. It is crucial to identify signs and criteria that come along with an increased risk of infection of the necroses. MRI plays an inferior role in the assessment of acute pancreatitis. Chronic pancreatitis is a longstanding inflammatory and fibrosing process causing pain and loss of function. Cross-section imaging is particularly in demand for the detection of complications and the differentiation from pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by lymphoplasmacytic infiltration and fibrosis, and favourable response to corticosteroid treatment. (orig.)

    Cachexia, malnutrition, significant weight loss, and reduction in food intake due to anorexia represent the most important pathophysiological consequences of pancreatic cancer. Pathophysiological consequences result also from pancreatectomy, the type and severity of which differ significantly and depend on the type of the operation performed. Nutritional intervention, either parenteral or enteral, needs to be seen as a method of support in pancreatic cancer patients aiming at the maintenance of the nutritional and functional status and the prevention or attenuation of cachexia. Oral nutrition could reduce complications while restoring quality of life. Enteral nutrition in the post-operative period could also reduce infective complications. The evidence for immune-enhanced feed in patients undergoing pancreaticoduodenectomy for pancreatic cancer is supported by the available clinical data. Nutritional support during the post-operative period on a cyclical basis is preferred because it is associated with low incidence of gastric stasis. Postoperative total parenteral nutrition is indicated only to those patients who are unable to be fed orally or enterally. Thus nutritional deficiency is a relatively widesoread and constant finding suggesting that we must optimise the nutritional status both before and after surgery.

    Full Text Available INTRODUCTION: Chronic pancreatitis predisposes to diabetes. Loss of endocrine function by β-cells in the Langerhans islets is considered to be the main causative factor, although several studies have also suggested insulin resistance as a possible additional mechanism. OBJECTIVES: The aim of the study was to estimate insulin sensitivity in chronic pancreatitis in view of the coexisting meta bolic syndrome components. PATIENTS AND METHODS: The study involved 30 patients (mean age 50.83 ±6.61 years; 23.33% women, 76.66% men diagnosed with chronic pancreatitis (using imaging tests. Insulin sensitivitywith regard to the coexistent obesity, dyslipidemia, and arterial hypertension was measured using the euglycemic clamp method. RESULTS: Diabetes was present in 22 patients, impaired glucose tolerance in 4, and no carbohydrate metabolism disturbances in 4. Insulin resistance was present in 22 patients (73.33%, in whom a higher prevalence of diabetes (77.27% vs. 62.5% and prediabetes (13.63% vs. 12.5% was observed. The analysis of anthropometric para meters revealed that individuals with a high index of central obesity had a statistically significantly lower tissue glucose utilization (TGU (3.23 vs. 4.89 mg/kg/min; P = 0.02, although there were no obese patients in the study group according to the body mass index. No statistically significant differences in TGU were observed in relation to lipid disorders (total cholesterol, low- and high-density lipoprotein cholesterol, triglycerides and arterial hypertension. CONCLUSIONS: In patients with chronic pancreatitis, lack of correlation between insulin sensitivity and metabolic syndrome components may indicate that insulin resistance is related to primary disease or that an additional mechanism underlying pancreatic diabetes operates.

    Thirty patients suffering from chronic alcoholic pancreatitis (18 calcified) were entered into a study of exocrine and endocrine pancreatic function based on two maximal stimulation tests, namely the secretin-cerulein test and the glucagon test with serum assays of C peptide. The glucagon test was also performed in 19 control subjects. In addition, 10 chronic pancreatitis patients and nine controls were subjected to an oral glucose tolerance test (OGTT) with serum insulin determinations. C peptide basal values were decreased only in patients with severe pancreatic exocrine insufficiency (P less than 0.001), while delta C peptide values were also reduced in patients with moderate exocrine insufficiency (P less than 0.001). Lipase output correlated very well with delta C peptide values (P less than 0.001). While serum insulin levels during OGTT and C peptide basal values showed no significant differences between the chronic pancreatitis and control groups, delta C peptide values were significantly reduced in chronic pancreatitis patients (P less than 0.02). Both endocrine and exocrine function are impaired in chronic pancreatitis, as demonstrated by maximal tests, even in early stages of the disease.

    OBJECTIVE: The authors sought to provide a framework through outcome analysis to evaluate operations directed toward the intractable abdominal pain of severe chronic pancreatitis centered in the pancreatic head. Pancreatoduodenectomy (PD) was used as an example. SUMMARY BACKGROUND DATA: Head resection for severe chronic pancreatitis is the treatment of choice for a ductal system in the head obliterated by severe disease when associated with intractable abdominal pain. To evaluate the effectiveness of promising head resection substitutes for PD, a framework is necessary to provide a reference standard (i.e., an outcome analysis) of PD. METHODS: Inclusion criteria were severe chronic pancreatitis centered in the pancreatic head, intractable abdominal pain, and a main pancreatic duct obstruction or stricture resulting in absent drainage into the duodenum from the uncinate process and adjacent pancreatic head areas or the entire gland. Since 1986, 57 consecutive cases with these criteria underwent PD (47 head only and 10 total pancreatectomy). Clinical and anatomic predictor variables were derived from the history, imaging studies, and pathologic examination. These variables then were tested for association with the following outcome events gathered during annual follow-up: pain relief, onset of diabetes, body weight maintenance, and peptic ulceration. RESULTS: Operative mortality was zero. In 57 patients with a mean follow-up of 42 months, the 5-year outcome event for survival was 93% and the onset of diabetes was 32%. All new cases of diabetes occurred more than 1 year after resection. In 43 cases > or =1 year postoperative with a mean follow-up of 55 months, all patients indicated significant pain relief and 76% were pain free. Pain relief was more common in patients with diabetes or in those patients with a pancreatic duct disruption. Death was more common in patients with diabetes. Weight maintenance was more common if preoperatively severe ductal changes were not

    2015-07-01

    Full Text Available We deeply appreciate your publishing of our work - “Chronic metabolic acidosis destroys pancreas” in JOP (2014 [1]. We feel that our work can give the food for thought to many young researchers and health practitioners. A short review of our work may generate various questions and ideas for further investigations. In our work, we have focused on negative affects of the chronic metabolic acidosis on pancreatic function including: • Premature activation of the proteases within the pancreas • Diminishing the antimicrobial activity of the pancreatic juice • Suppressing of the flushing out zymogens from the pancreas • Precipitation of the aggressive bile acids • Calcification Authors believe that further research may provide more details of how the acidification destroys the pancreas and causes chronic pancreatitis. We would like to share some of our thoughts on this subject as follows: Descriptions of symptoms of chronic pancreatitis such as pain, malabsorption syndrome, steatorrhea, and weight loss are found in almost all medical books, textbooks, and articles. The medical literature refers to these conditions as “pancreatic insufficiency”. It is known that these symptoms occur when only 10 % of the exocrine pancreatic function is left intact. This is not an “insufficiency.” It is a pancreatic “failure” when the therapeutic opportunities are very limited.

    ática.The pancreas is a retroperitoneal organ that releases water, bicarbonate and digestive enzymes by the main pancreatic duct (MPD into the duodenum. Chronic pancreatitis (CP is typically caused, in adults, by chronic alcohol abuse and, less frequently hypertriglyceridemia, primary hyperparathyroidism or chystic fibrosis. Exocrine dysfunction results in malabsorption of fat and subsequent steatorrhea. Damage to pancreatic endocrine function is a late finding in CP and results in hyperglycaemia or overt diabetes mellitus. Care of patients with CP principally involves management of pain. A significant change in the pain pattern or the sudden onset of persistent symptoms suggests the need to rule out other potential etiologies, including peptic ulcer disease, biliary obstruction, pseudocysts, pancreatic carcinoma, and pancreatic duct stricture or stones, then is important to establish a secure diagnosis. Management of pain should then proceed in a judicious stepwise approach avoiding opioids dependence. Patients should be advised to stop alcohol intake. Fat malabsorption and other complications may also arise. Management of steatorrhea should begin with small meals and restriction in fat intake. Pancreatic enzyme supplements can relieve symptoms and reduce malabsorption in patients who do not respond to dietary restriction. Enzymes at high doses should be used with meals. Treatment with acid suppression to reduce inactivation of the enzymes from gastric acid are recommended. Supplementation with medium chain triglycerides and fat soluble vitamin replacement may be required. Management of other complications (such as pseudocysts, bile duct or duodenal obstruction, pancreatic ascites, splenic vein thrombosis and pseudoaneurysms often requires aggressive approach with the patient kept on total parenteral nutrition to minimize pancreatic stimulation.

    Placental insufficiency is associated with reduced supply of amino acids to the fetus and leads to intrauterine growth restriction (IUGR). IUGR fetuses are characterized by lower glucose-stimulated insulin secretion, smaller pancreatic islets with less β-cells, and impaired pancreatic vascularity. To test whether supplemental amino acids infused into the IUGR fetus could improve these complications of IUGR we used acute (hours) and chronic (11 d) direct fetal amino acid infusions into a sheep model of placental insufficiency and IUGR near the end of gestation. IUGR fetuses had attenuated acute amino acid-stimulated insulin secretion compared with control fetuses. These results were confirmed in isolated IUGR pancreatic islets. After the chronic fetal amino acid infusion, fetal glucose-stimulated insulin secretion and islet size were restored to control values. These changes were associated with normalization of fetal pancreatic vascularity and higher fetal pancreatic vascular endothelial growth factor A protein concentrations. These results demonstrate that decreased fetal amino acid supply contributes to the pathogenesis of pancreatic islet defects in IUGR. Moreover, the results show that pancreatic islets in IUGR fetuses retain their ability to respond to increased amino acids near the end of gestation after chronic fetal growth restriction.

    Full Text Available Context ERCP can provide information which is invaluable in managing chronic pancreatitis but it is associated withinfrequent, although significant, complications and rare mortality. The complications uniquely associated withdiagnostic ERCP include pancreatitis and sepsis (primary cholangitis. Case report A 32-year-old man presented with severe upper abdominal pain radiating to the back, associated with vomiting and abdominal distension. The patient was diagnosed as having had chronic calcific pancreatitis recently and had undergone ERCP with pancreatic duct stenting elsewhere. Two days after the procedure, the patient developed severe abdominal pain, vomiting and abdominal distention, and patient was referred to our hospital 7 days after the procedure. Investigation revealed massive liver necrosis and portal vein thrombosis. This patient had a life-threatening complication following pancreatic duct stenting for chronic pancreatitis and was managed medically.Conclusion Therapeutic pancreatic endoscopy procedures are technically demanding and should be restricted to highvolume centers. There is a continuing need for evaluation and comparison with alternative strategies. In a good surgical candidate, it is better to avoid stenting.

    Full Text Available We retrospectively evaluated the results of pancreatic juice cultures of patients with acute pancreatitis and other pancreatic disorders. Methods Twenty patients who underwent pancreatic juice culture were studied. Nine had acute pancreatitis due to alcohol (n=5, idiopathic causes (n=2, drugs (n=1, or gallstones (n=1, and remaining 11 had other pancreatic disorders such as an intraductal papillary mucin-producing neoplasm (n=3 and main pancreatic duct dilatation with a stricture due to a tumorous lesion suspected of pancreatic cancer (n=7 or chronic pancreatitis (n=1 without symptoms. Nasopancreatic drainage tubes were placed for pancreatic duct drainage in acute pancreatitis and for pancreatic juice cytology in other disorders. Pancreatic juice was obtained through the drainage tube and cultured. Results Pancreatic juice cultures were positive in all patients with acute pancreatitis for Staphylococcus epidermidis, Streptococcus species, and others. Six among 11 patients (54.5% with other disorders showed positive results for Escherichia coli, Streptococcus salivarius, and others. The rate of positive pancreatic juice cultures was significantly higher in acute pancreatitis (p=0.038. Seven of the 9 patients with acute pancreatitis were classified as having severe acute pancreatitis, and all survived treatment. Conclusions Pancreatic juice culture was highly positive in acute pancreatitis. Further study is needed to confirm the relationship between orally indigenous bacteria identified in the pancreatic juice and acute pancreatitis.

    Full Text Available Hemosuccus pancreaticus is an unusual cause of gastrointestinal bleeding that occurs as a complication of chronic or acute pancreatitis. We report a case of extremely acute-onset hemosuccus pancreaticus occurring in a patient with chronic pancreatitis over a long-term follow-up after a Puestow procedure (side-to-side pancreaticojejunostomy. The patient was admitted to our hospital due to severe anemia and tarry stools indicative of gastrointestinal bleeding. Emergent endoscopy, including gastrointestinal fiberscopy and colon fiberscopy, showed no abnormal findings. Abdominal contrast-enhanced computed tomography and hemorrhagic scintigraphy did not detect a hemorrhagic lesion. Although interventional radiology was considered for diagnosis and treatment, conservative therapy seemed sufficient to affect hemostasis. Two weeks later, however, acute intestinal bleeding with hemodynamic shock occurred, and exploration was performed without delay. Intraoperative endoscopy through an incision of the reconstructed jejunal loop in the close proximal end revealed a site of active bleeding from the side-to-side anastomotic pancreatic duct. Following a longitudinal incision of the jejunal loop, a bleeding point was sutured and ligated on direct inspection. The patient showed a good postoperative course.

    Chronic ethanol consumption is well established as a major risk factor for type-2 diabetes(T2D), which is evidenced by impaired glucose metabolism and insulin resistance. However, the relationships between alcoholconsumption and the development of T2 D remain controversial. In particular, the direct effects of ethanol consumption on proliferation of pancreatic β-cell and the exact mechanisms associated with ethanolmediated β-cell dysfunction and apoptosis remain elusive. Although alcoholism and alcohol consumption are prevalent and represent crucial public health problems worldwide, many people believe that low-tomoderate ethanol consumption may protect against T2 D and cardiovascular diseases. However, the J- or U-shaped curves obtained from cross-sectional and large prospective studies have not fully explained the relationship between alcohol consumption and T2 D. This review provides evidence for the harmful effects of chronic ethanol consumption on the progressive development of T2 D, particularly with respect to pancreatic β-cell mass and function in association with insulin synthesis and secretion. This review also discusses a conceptual framework for how ethanolproduced peroxynitrite contributes to pancreatic β-cell dysfunction and metabolic syndrome.

    Full Text Available The aim of the study was to investigate the effects of Vitamin A and Vitamin E on activity of pancreatic stellate cells and fibrosis changes in pancreas after distal pancreatectomy in rats with experimental alcohol-induced chronic pancreatitis. Simultaneously Vitamin A and Vitamin E were administered after distal pancreatectomy in rats with experimental alcohol-induced chronic pancreatitis. The animals were treated withVitamin A at the dose of 33000 IU/kg body weight per day and Vitamin E at the dose of 100 mg/kg body weight per day for three weeks (21 days after operation. To estimate the efficacy of the treatment on activity and numbersof pancreatic stellate cells the immunohistochemicalinvestigation was made with alpha-smooth muscle actin, desmin, vimentin, glial fibrillary acidic protein (GFAP, matrix metalloproteinase 1 (MMP1, tissue inhibitor of metalloproteinase 2 (TIMP2 using. The treatment of rats after operation with vitamin A and vitamin E inhibited activity of pancreatic stellate cells and characterized by significant decreasing of the alpha-smooth muscle actin, Desmin, Vimentin, MMP1 and TIMP2 expression. The ratio of MMP1/TIMP2 was greater in the group with treatment then in the control group. This therapy had a trend to decrease the expression of GFAPand alleviate the fibrotic changes in pancreas.

    Chronic exposure to alcohol affects different physiological aspects of pancreatic acinar cells (PAC), but its effect on the uptake process of biotin is not known. We addressed this issue using mouse-derived pancreatic acinar 266-6 cells chronically exposed to alcohol and wild-type and transgenic mice (carrying the human SLC5A6 5'-promoter) fed alcohol chronically. First we established that biotin uptake by PAC is Na(+) dependent and carrier mediated and involves sodium-dependent multivitamin transporter (SMVT). Chronic exposure of 266-6 cells to alcohol led to a significant inhibition in biotin uptake, expression of SMVT protein, and mRNA as well as in the activity of the SLC5A6 promoter. Similarly, chronic alcohol feeding of wild-type and transgenic mice carrying the SLC5A6 promoter led to a significant inhibition in biotin uptake by PAC, as well as in the expression of SMVT protein and mRNA and the activity of the SLC5A6 promoters expressed in the transgenic mice. We also found that chronic alcohol feeding of mice is associated with a significant increase in the methylation status of CpG islands predicted to be in the mouse Slc5a6 promoters and a decrease in the level of expression of transcription factor KLF-4, which plays an important role in regulating SLC5A6 promoter activity. These results demonstrate, for the first time, that chronic alcohol exposure negatively impacts biotin uptake in PAC and that this effect is exerted (at least in part) at the level of transcription of the SLC5A6 gene and may involve epigenetic/molecular mechanisms.

    Pancreatitis is a rare, life-threatening complication of systemic lupus erythematosus (SLE). This study aimed to describe the clinical features of acute pancreatitis (AP) and chronic pancreatitis (CP) in patients with SLE. Data of patients who fulfilled the revised criteria of the American Rheumatism Association for diagnosis of SLE were retrospectively analyzed. SLE activity was graded according to the SLE Disease Activity Index. Logistic regression analysis was conducted to find out independent associations. Survival rates were estimated by using Kaplan-Meier plots. This study included 5665 SLE patients admitted between January 1983 and January 2014, of whom 52 patients were diagnosed with pancreatitis. Pancreatitis prevalence in SLE patients was 0.92 % (52/5665). AP (0.8 %, 46/5665) was more prevalent than CP (0.1 %, 6/5665), presented mostly during active SLE, and affected more organs. Hypertriglyceridemia occurred in 76.9 % of AP patients and in none of the CP patients. AP patients were divided into severe (n = 10) or mild (n = 20) cases. The average triglyceride level in severe AP cases was higher than that in mild AP cases (P = 0.006), and the mortality rate of lupus-associated AP was 32.6 % (15/46). Concomitant infections and thrombocytopenia were independently associated with poor prognosis (P < 0.001, P = 0.028, respectively). There were significant differences in the clinical manifestations of AP and CP. Patients with severe AP were found to have a higher incidence of concomitant infection and serum triglyceride levels. Concomitant infections and thrombocytopenia were independent risk factors for poor prognosis.

    AIM: To investigate whether gastric myoelectricai activity was impaired in patients with chronic pancreatitis (CP)and to explore the role of pancreatic enzyme in regulating gastric myoeiectrical activity.METHODS: Twenty CP patients and 20 controls participated in the study. Gastric myoelectrical activity was recorded by a homemade electrogastrography (EGG) device. Two experiments were carried out. In experiment one, EGG was recorded in both controls and CP patients. While in experiment two, either pancreatic enzymes or placebo was given together with test meals. Spectral analysis was used to generate various EGG parameters.RESULTS: The control subjects, but not the CP patients,showed typically increased postprandial dominant frequency. The postprandial dominant power (DP)increment (2.24±1.13 vs 5.35±0.96 dB, P= 0.04) and the percentage of normal 2-4 cpm slow waves (63.0±3.8% vs 77.4 ±3.1%, P<0.05) were lower in CP patients when compared with the control. In the 20 CP patients, the DP increment (4.76±1.02 vs 2.53±1.20 dB, P<0.05) and the postprandial percentage of normal 2-4 cpm (74.4±2.8%vs 64.8 ±5.7%, P<0.05) were significantly higher with pancreatic enzyme replacement than the placebo.ONCLUSION: CP patients have an abnormal postprandial stomach myoelectricity showing poor response in dominant frequency/power and regularity, whereas these abnormalities are corrected after pancreatic enzyme replacement.Maldigestion is likely to be the factor leading to abnormal postprandial gastric myoelectriclty of CP patients.

    Full Text Available Background. Pancreatic ductal adenocarcinoma (PDAC is an aggressive disease with rapid tumor progression and poor prognosis. This study was motivated by the lack of sensitive and specific PDAC biomarkers and aimed to identify a diagnostic, serum protein signature for PDAC. Methods. To mimic a real life test situation, a multicenter trial comprising a serum sample cohort, including 338 patients with either PDAC or other pancreatic diseases (OPD and controls with nonpancreatic conditions (NPC, was analyzed on 293-plex recombinant antibody microarrays targeting immunoregulatory and cancer-associated antigens. Results. Serum samples collected from different hospitals were analyzed and showed that (i sampling from five different hospitals could not be identified as a preanalytical variable and (ii a multiplexed biomarker signature could be identified, utilizing up to 10 serum markers that could discriminate PDAC from controls, with sensitivities and specificities in the 91–100% range. The first protein profiles associated with the location of the primary tumor in the pancreas could also be identified. Conclusions. The results demonstrate that robust enough serum signatures could be identified in a multicenter trial, potentially contributing to the development of a multiplexed biomarker immunoassay for improved PDAC diagnosis.

    Full Text Available The aim of the study was to examine the quality of life and clinical features of non-psychotic mental disorders in patients with acute and chronic pancreatitis. Polymorphic mental disorders of different clinical content and severity in most cases not only comorbid diseases of the pancreas, but often are the first earliest clinical manifestations of the disease. The data on clinical and psychopathological features of non-psychotic mental disorders in patients with acute and chronic pancreatitis are given. The share of cardinal syndromes such as asthenic-neurotic and anxious-depressive was established and described. The study was conducted using the following methods: clinical psychiatric questionnaire of common type MOS Short Form-36 Health Survey (SF-36 and methods of mathematical processing. The sample included 131 patients with acute and chronic pancreatitis. Clinical variant of acute and chronic pancreatitis debut were the features of mental disorders and psychotic-pathologic structure of non-psychotic mental disorders. Various indicators of quality of life in acute and chronic pancreatitis in presence of psychotic disorders were revealed.

    Full Text Available The study was undertaken to examine the influence of chronic pancreatitis on the distribution of neuronal cell adhesion molecule (NCAM in the pancreas and various brain regions of rats under the conditions of endogenous intoxication. The study was conducted using 36 white nonlinear male rats (6 months old, 190–220 g. To develop the state of chronic pancreatitis, animals were subjected tolaparotomy under general anesthesia and prolonged occlusion of the pancreatic duct. The morphological examination of pancreatic tissue hasbeen performed to confirm the chronic pancreatitis development in animals. Biochemical evaluation of the pancreatic fibrosis has been performed by measuring plasma levels of hyaluronic acid, hydroxyproline and protein-free hydroxyproline. The intensity of free radical oxidation has been assessed by the change in the concentration of TBA-active products in plasma. The level of endotoxemia has been determinedby the content of average weight molecules in plasma. Protein fractions were extracted from the pancreas and various parts of the rat brain and the levels of soluble (sNCAM and membrane (mNCAM proteins were studied with the use of the competitive ELISA. Total protein in the obtained fractions was measured by the Bradford assay. Occlusion of the pancreatic duct resultedin significant atrophy of acinar tissue, fibrosis and disfunction of the pancreas along with the decreasing in the antioxidant defense of animals. The present study shows developing of endointoxication in experimentalrats, signified by considerable increase of molecules with average weight in plasma due to the activation of lipid peroxidation. It was established that, as a result of the experimental pancreas dysfunction, significant redistribution of soluble and membrane forms of NCAM took place, more especially in the cerebellum and thalamus of rats; it caused changing of cell-cell adhesion in these brain regions.

    The aim of this study was to quantify pancreatic exocrine function in normal subjects and in patients with chronic pancreatitis (CP) before and after pancreatic duct drainage procedures (PDDP) with dynamic secretin-enhanced magnetic resonance (MR) cholangiopancreatography (S-MRCP). Pancreatic exocrine secretions [quantified by pancreatic flow output (PFO) and total excreted volume (TEV)] were quantified twice in ten healthy volunteers and before and after treatment in 20 CP patients (18 classified as severe, one as moderate, and one as mild according to the Cambridge classification). PFO and TEV were derived from a linear regression between MR-calculated volumes and time. In all subjects, pancreatic exocrine fluid volume initially increased linearly with time during secretin stimulation. In controls, the mean PFO and TEV were 6.8 ml/min and 97 ml; intra-individual deviations were 0.8 ml/min and 16 ml. In 10/20 patients with impaired exocrine secretions before treatment, a significant increase of PFO and TEV was observed after treatment (P<0.05); 3/20 patients presented post-procedural acute pancreatitis and a reduced PFO. The S-MRCP quantification method used in the present study is reproducible and provides normal values for PFO and TEV in the range of those obtained from previous published intubation studies. The initial results in CP patients have demonstrated non-invasively a significant short-term improvement of PFO and TEV after PDDP. (orig.)

    The histotoxic effects of chronic cyanide insult on heart, lung and pancreatic tissues, and some corroborative enzyme and metabolite changes were studied in New Zealand White rabbits using colorimetric, enzymatic and histochemical methods. Two groups of rabbits were fed for 10 months on either pure growers mash or grower mash +702 ppm inorganic cyanide. There were no significant differences in time-course profiles of serum amylase and fasting blood glucose between the cyanide-fed group and control. Pancreatic islet and heart histologies showed no pathological changes, and there were no significant differences in both serum and heart aspartate transaminase activities between the two groups. However, there were significant decreases (Pactivity in the lungs of the cyanide-fed group, with corresponding significant (Pactivity of the enzyme. Histological examination of lung tissue of the cyanide-treated rabbits revealed focal areas of pulmonary oedema and necrosis. These results suggest the existence of variabilities in tissue susceptibilities to the toxic effect of chronic cyanide exposure. It would appear that chronic cyanide exposure may not predispose to diabetes in the presence of adequate protein intake.

    Acinar cells represent the primary target in necroinflammatory diseases of the pancreas, including pancreatitis. The signaling pathways guiding acinar cell repair and regeneration following injury remain poorly understood. The purpose of this study was to determine the importance of Hepatocyte Growth Factor Receptor/MET signaling as an intrinsic repair mechanism for acinar cells following acute damage and chronic alcohol-associated injury. Here, we generated mice with targeted deletion of MET in adult acinar cells (MET-/-). Acute and repetitive pancreatic injury was induced in MET-/- and control mice with cerulein, and chronic injury by feeding mice Lieber-DeCarli diets containing alcohol with or without enhancement of repetitive pancreatic injury. We examined the exocrine pancreas of these mice histologically for acinar death, edema, inflammation and collagen deposition and changes in the transcriptional program. We show that MET expression is relatively low in normal adult pancreas. However, MET levels were elevated in ductal and acinar cells in human pancreatitis specimens, consistent with a role for MET in an adaptive repair mechanism. We report that genetic deletion of MET in adult murine acinar cells was linked to increased acinar cell death, chronic inflammation and delayed recovery (regeneration) of pancreatic exocrine tissue. Notably, increased pancreatic collagen deposition was detected in MET knockout mice following repetitive injury as well alcohol-associated injury. Finally, we identified specific alterations of the pancreatic transcriptome associated with MET signaling during injury, involved in tissue repair, inflammation and endoplasmic reticulum stress. Together, these data demonstrate the importance of MET signaling for acinar repair and regeneration, a novel finding that could attenuate the symptomology of pancreatic injury. PMID:27798657

    Full Text Available Background. Patients with chronic pancreatitis (CP exhibit numerous risk factors for the development of small intestinal bacterial overgrowth (SIBO. Objective. To determine the prevalence of SIBO in patients with CP. Methods. Prospective, single-centre case-control study conducted between January and September 2013. Inclusion criteria were age 18 to 75 years and clinical and radiological diagnosis of CP. Exclusion criteria included history of gastric, pancreatic, or intestinal surgery or significant clinical gastroparesis. SIBO was detected using a standard lactulose breath test (LBT. A healthy control group also underwent LBT. Results. Thirty-one patients and 40 controls were included. The patient group was significantly older (53.8 versus 38.7 years; P < 0.01. The proportion of positive LBTs was significantly higher in CP patients (38.7 versus 2.5%: P < 0.01. A trend toward a higher proportion of positive LBTs in women compared with men was observed (66.6 versus 27.3%; P = 0.056. The subgroups with positive and negative LBTs were comparable in demographic and clinical characteristics, use of opiates, pancreatic enzymes replacement therapy (PERT, and severity of symptoms. Conclusion. The prevalence of SIBO detected using LBT was high among patients with CP. There was no association between clinical features and the risk for SIBO.

    Pain is a common symptom of pancreatic disease and is frequently difficult to manage. Pain relief provided by narcotics is often suboptimal and is associated with significant side effects. An alternative approach to pain management in pancreatic disease is the use of celiac plexus block (CPB) or neurolysis (CPN). Originally performed by anesthesiologists and radiologists via a posterior approach, recent advances in endoscopic ultrasonography (EUS) have made this technique an attractive alternative. EUS guided celiac plexus block/neurolysis is simple to perform and avoids serious complications such as paraplegia or pneumothorax that are associated with the posterior approach. EUS guided CPN should be considered first line therapy in patients with pain due to pancreatic cancer. It provides superior pain control compared to traditional management with narcotics. A trend for improved survival in pancreatic cancer patients treated with CPN has been reported,but larger studies are needed to confirm this finding.At this time, the use of EUS guided CPB cannot be recommended as routine therapy for pain in chronic pancreatitis since only one-half of the patients experience pain reduction and the beneficial effect tends to be short lived. EUS guided CPB and CPN should be used as part of a multidisciplinary team approach for pain management.

    Glucagon-like peptide-1 (GLP-1) promotes insulin release; however, the relationship between the GLP-1 signal and chronic pancreatitis is not well understood. Here we focus on chemokine (C-C motif) ligand 2 (CCL2) and its receptor (CCR2) axis, which regulates various immune cells, including macrophages, to clarify the mechanism of GLP-1-mediated insulin secretion in chronic pancreatitis in mice. One and multiple series of repetitive cerulein administrations were used to induce acute and chronic cerulein pancreatitis, respectively. Acute cerulein-administered CCR2-knockout (KO) mice showed suppressed infiltration of CD11b(+)Gr-1(low) macrophages and pancreatic inflammation and significantly upregulated insulin secretion compared with paired wild-type (WT) mice. However, chronic cerulein-administered CCR2-KO mice showed significantly increased infiltration of CD11b(+)/Gr-1(-) and CD11b(+)/Gr-1(high) cells, but not CD11b(+)/Gr-1(low) cells, in pancreas with severe inflammation and significantly decreased insulin secretion compared with their WT counterparts. Furthermore, although serum GLP-1 levels in chronic cerulein-administered WT and CCR2-KO mice were comparably upregulated after cerulein administrations, GLP-1 receptor levels in pancreases of chronic cerulein-administered CCR2-KO mice were significantly lower than in paired WT mice. Nevertheless, a significantly higher hyperglycemia level in chronic cerulein-administered CCR2-KO mice was markedly restored by treatment with a GLP-1 analog to a level comparable to the paired WT mice. Collectively, the CCR2/CCL2 axis-mediated CD11b(+)-cell migration to the pancreas is critically involved in chronic pancreatitis-mediated hyperglycemia through the modulation of GLP-1 receptor expression and insulin secretion.

    Acute and chronic pancreatitis are most frequently caused by a high consumption of alcohol and tobacco but often the aetiology is unknown. The diseases have a high risk of complications, but the long-term prognosis and the natural course of the diseases are only sparsely described. The aims of the study were to investigate the long-term prognosis of acute pancreatitis (AP) and chronic pancreatitis (CP), the risk of progression to CP, and the natural course of progressive acute pancreatitis. Hereby, describe the prognostic factors associated with mortality and the causes of death in these patients. The study was based on the large prospective cohort study - Copenhagen Pancreatitis Study - of patients in the Copenhagen Municipality admitted with either AP or CP fulfilling specific diagnostic criteria and enrolled in the study during 1977 to 1982 and in 2008 followed up by linkage to the Danish registries. Factors associated with mortality in AP patients were high age, alcohol and diabetes, whereas female gender, employment, and co-living were associated with better survival. Level of S-amylase had no impact on the mortality. AP can progress to CP not only from alcoholic but also from idiopathic AP within a mean interval of 3.5 years. The mortality of progressive AP was 5-7 times higher compared with the background population. Patients with definite CP had a 4-fold higher mortality than the background population and patients with a suspicion of CP had twice the mortality compared with the background population. Unlike alcohol and smoking, both non-employment and being underweight had a significant impact on survival in CP patients. In the future, when diagnosing AP, we suggest focusing more on the elimination of differential diagnosis than on the level of S-amylase. The high mortality in progressive AP indicates that patients with risk factors for CP should be followed up. As both AP and CP are multifaceted, treatment for smoking dependency, alcohol dependency, and

    To determine which abdominal CT findings predict severe fibrosis and post-operative pain relief in chronic pancreatitis (CP). Pre-operative abdominal CTs of 66 patients (mean age 52 ± 12 years, 53 % males) with painful CP who underwent the Whipple procedure (n = 32), Frey procedure (n = 32) or pancreatic head biopsy (n = 2), between 1/2003-3/2014, were evaluated. CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

    AIM: To study the possible association between chronic pancreatitis (CP) and liver cirrhosis (LC) of alcoholic etiology, after excluding any other causes. METHODS: One hundred and forty consecutive alcoholic patients were subdivided into three groups: CP (η = 53), LC (η = 57), and asymptomatic alcoholic (n = 30). Clinical, biochemical and morphological characteristics, Child-Pugh index, indocyanine green test, and fecal pancreatic elastase-1 test were assessed. RESULTS: In patients with cirrhosis, major clinical manifestations of CP such as pancreatic pain and steatorrhea, as well as imaging alterations of CP such as calcifications, duct dilation and pseudocysts were absent; insulin-dependent diabetes was present in 5.3% of cases, and elastase-1 test was altered in only 7%, and severely altered in none. In patients with CP, clinical characteristics of cirrhosis such as ascites, encephalopathy and gastrointestinal hemorrhage were present in one case, Child-Pugh grade > A in 5.7%, and altered indocyanine green test in 1.9% cases. In asymptomatic alcoholism, there was only a non-coincident alteration of elastase-1 test and indocyanine test in 14.8% and 10%, respectively, but other characteristics of cirrhosis or CP were absent. An inverse correlation (r=-0.746) between elastase-1 test and indocyanine test was found in alcoholic patients. CONCLUSION: There is a scarce coincidence in clinical and morphological alterations among patients with CP or LC of alcoholic etiology, but an inverse correlation between pancreatic and liver function tests. These findings support that these alcoholic diseases evolve in a different manner and have different etiopathogenesis.

    The glial cell line-derived neurotrophic factor (GDNF) family member neurturin (NRTN) and its receptor GFRα2 play a deciding role in the normal development of pancreatic parasympathetic innervation. In this study, we aimed at investigating the role of NRTN/GFRα2 axis in pancreatic neuropathy in human chronic pancreatitis (CP). Expression of NRTN/GFRα2 was compared between normal human pancreas (NP) and CP tissues via immunohistochemistry, immunoblotting, and quantitative RT-PCR and correlated to abdominal pain sensation. To elucidate the impact of NRTN in pancreatic neuroplasticity, neuronal phenotype and glial density were quantified via an in vitro neuroplasticity assay in dissociated newborn rat dorsal root ganglia (DRG) cultured 1) in CP tissue extracts depleted from NRTN, 2) in NP, 3) in untreated CP tissue extracts, and 4) CP extracts in which nerve growth factor, glial cell derived-neurotrophic factor, or TGF-β(1) was depleted. NRTN and GFRα2 were highly upregulated in CP, especially in intrapancreatic nerves and the extracellular matrix. CP tissue demonstrated increased amounts of mature multimeric NRTN and elevated levels of GFRα2. The noticeable neurotrophic effect of CP tissue extracts on DRG neurons was diminished upon blockade of NRTN from these extracts. However, blockade of NRTN from CP extracts did not influence the density of DRG glia cells. In conclusion, the NRTN/GFRα2 axis is activated during the course of CP and represents a major key player in the reactive neural alterations in CP. This is the first study to provide functional evidence for the contribution of neurotrophic factors to neuroplasticity in CP.

    Full Text Available The circulating renin-angiotensin system (RAS plays an important role in the maintenance of blood pressure and fluid homeostasis. Recently, there has been a shift of emphasis from the circulating RAS to the local RAS in the regulation of individual tissue functions via a paracrine and/or autocrine mechanism. In fact, a local RAS has been proposed to be present in an array of tissues including the brain, heart, kidney and gonads. Our previous studies have provided solid evidence that several key elements of the RAS, notably angiotensinogen and renin, are present in the rat pancreas. The data support the existence of an intrinsic RAS in the pancreas and this local RAS may be important for the exocrine/endocrine functions of the pancreas. Interestingly, such a pancreatic RAS has been demonstrated to be markedly activated by experimental rat models of chronic hypoxia and acute pancreatitis. The activation of the pancreatic RAS by chronic hypoxia and experimental pancreatitis could play a role in the physiology and pathophysiology of the pancreas. The significant changes of pancreatic RAS may have clinical relevance to acute pancreatitis and hypoxia-induced injury in the pancreas.

    AIM To investigate endoscopic therapy efficacy for refractory benign biliary strictures (BBS) with multiple biliary stenting and clarify predictors. METHODS Ten consecutive patients with stones in the pancreatic head and BBS due to chronic pancreatitis who underwent endoscopic therapy were evaluated. Endoscopic insertion of a single stent failed in all patients. We used plastic stents (7F, 8.5F, and 10F) and increased stents at intervals of 2 or 3 mo. Stents were removed approximately 1 year after initial stenting. BBS and common bile duct (CBD) diameter were evaluated using cholangiography. Patients were followed for ≥ 6 mo after therapy, interviewed for cholestasis symptoms, and underwent liver function testing every visit. Patients with complete and incomplete stricture dilations were compared. RESULTS Endoscopic therapy was completed in 8 (80%) patients, whereas 2 (20%) patients could not continue therapy because of severe acute cholangitis and abdominal abscess, respectively. The mean number of stents was 4.1 ± 1.2. In two (20%) patients, BBS did not improve; thus, a biliary stent was inserted. BBS improved in six (60%) patients. CBD diameter improved more significantly in the complete group than in the incomplete group (6.1 ± 1.8 mm vs 13.7 ± 2.2 mm, respectively, P = 0.010). Stricture length was significantly associated with complete stricture dilation (complete group; 20.5 ± 3.0 mm, incomplete group; 29.0 ± 5.1 mm, P = 0.011). Acute cholangitis did not recur during the mean follow-up period of 20.6 ± 7.3 mo. CONCLUSION Sequential endoscopic insertion of multiple stents is effective for refractory BBS caused by chronic calcifying pancreatitis. BBS length calculation can improve patient selection procedure for therapy. PMID:28101303

    Total pancreatectomy (TP) for chronic pancreatitis (CP) has not gained widespread acceptance because of concerns regarding technical complexity, diabetic complications, and uncertainty with respect to long-term pain relief. Records of patients having TP from 1997 to 2005 were reviewed. Patient presentation, etiology of disease, and the indication for TP were examined. Operative results were analyzed. Long-term results were critically assessed, including narcotic usage and the need for re-admission. Postoperative quality of life (QOL) was assessed by the SF-36 health survey. During the study period, 7 patients with CP had TP, and 28 had other operations. The etiology of CP was alcohol in four and hereditary pancreatitis in three. The indication for surgery was pain and weight loss. Preoperatively, all patients used narcotics chronically and two had insulin-dependent diabetes. Four had TP after failed previous surgical procedures. Endoscopic retrograde cholangiopancreatography and computed tomography demonstrated small ducts and atrophic calcified glands. The mean length of the operation was 468 minutes, and only two patients required transfusion. There were no biliary anastomotic complications. The mean length of stay was 14 days. Major morbidity was limited to a single patient with a leak from the gastrojejunal anastomosis. Thirty-day mortality was zero, with one late death unrelated to the surgical procedure or diabetes. The mean length of follow-up was 46 months. All patients remained alcohol and narcotic free. No patient was readmitted with a diabetic complication. When compared with the general population, QOL scores were diminished but reasonable. We conclude that TP is indicated in hereditary pancreatitis and in those with an atrophic, calcified pancreas with small duct disease; that TP is technically arduous but can be completed with very low morbidity and mortality; and that on long-term follow-up, pain relief and abstinence from alcohol and narcotics was

    Objective To investigate the relationship between alcohol and smoking and the development of pancreatic calcification in chronic pancreatitis (CP) in China. Methods The patients were divided into two groups according to the presence of pancreatic calcification at admission and the data were analyzed; furthermore, the discharged patients without pancreatic calcification were divided into two groups as newly diagnosed pancreatic calcification group and persistent non-pancreatic calcification group. Logistic regression and Cox proportional-hazards model was used for multivariate analysis of the risk factors for pancreatic calcification. Results From January1997 to July 2007, 449 patients with CP were enrolled and followed up successfully. 248 patients presented with pancreatic calcification at admission; among the 201 patients presented without pancreatic calcification, 13 patients developed pancreatic calcification after discharge. Patients with pancreatic calcification had a young age at onset, long CP history, higher incidence of diabetes mellitus and diarrhea. Age at onset ≤ 40, alcohol intake over 20 g/day, and diabetes mellitus and diarrhea were risk factors for pancreatic calcification. The only risk factor of development of pancreatic calcification after discharge was excessive alcohol intake (OR: 3.2). Conclusions Alcohol intake increased the risk of pancreatic calcifications, suggesting the patients abstain from alcohol intake. Further studies are necessary to clarify the role of smoking.%目的 探讨国内慢性胰腺炎(CP)患者烟酒摄入量与发生胰腺钙化间的关系.方法 按入院时有无胰腺钙化分为两组进行比较分析,再将无胰腺钙化者出院后有无新发胰腺钙化分为新发组和持续无钙化组.Logistic回归或Cox比例风险模型进行逐步回归分析胰腺钙化的风险因素.结果 1997年1月到2007年7月共收治并成功随访449例CP患者,248例有胰腺钙化;201例无胰腺钙化,其中13例出

    Objective Quantitative determination of fecal fat still is the gold standard for measuring malabsorption. We evaluated the importance of standardized food intake before and under the collection of feces. Material and Methods In a project, evaluating patients with suspected chronic pancreatitis (CP) and healthy volunteers (HC), stools were collected for 72 hours coupled to registration of nutritional intake over five consecutive days. Patient groups were created by a modified Layer score, which includes imaging findings, clinical parameters and pancreas function testing. Results We found 12 patients with CP, 11 patients without CP and 13 healthy individuals in our database. Median fecal fat in CP patients was 12 g/day, in non-CP patients 5 g/day and in healthy controls 5 g/day. Median fat absorption coefficient was 81% in those with chronic pancreatitis, 92% in those without CP and 92% in healthy controls. Corresponding median fat intake was 65 g/day, 68 g/day and 81 g/day in the respective groups. Spearman Rank Order Correlation between fecal fat (g/d) and fat absorption coefficient in all study subjects (n = 36) was good (-0.88 (p<0.001)). When we stratified groups according to fat intake, correlation between fecal fat and fat absorption was also good (-0.86 to -0.95). Conclusion In the diagnoses of fat malabsorption, calculating the ratio of fat absorption did not give additional information compared to fecal fat. PMID:28095460

    AIM: To prove the hypothesis that patients with chronic pancreatitis would show increased theta activity during painful visceral stimulation.METHODS: Eight patients and 12 healthy controls underwent an experiment where the esophagus was electrically stimulated at the pain threshold using a nasal endoscope. The electroencephalogram (EEG) was recorded from 64 surface electrodes and "topographic matching pursuit" was used to extract the EEG information in the early brain activation after stimulation.RESULTS: A major difference between controls and patients were seen in delta and theta bands, whereas there were only minor differences in other frequency bands. In the theta band, the patients showed higher activity than controls persisting throughout the 450 ms of analysis with synchronous brain activation between the channels. The main theta components oscillated with 4.4Hz in the patients and 5.5Hz in the controls. The energy in the delta (0.5-3.5Hz) band was higher in the controls, whereas the patients only showed scattered activity in this band.CONCLUSION: The differences in the theta band indicate that neuropathic pain mechanisms are involved in chronic pancreatitis. This has important implications for the understanding and treatment of pain in these patients, which should be directed against drugs with effects on neuropathic pain disorders.

    The First Surgical Clinic of the First Medical Faculty Charles University and General Faculty Hospital Prague made operations of the pancreas ever since 1971. In the work sooner or later all approaches to surgical treatment of pancreatitis were reflected. The authors present a brief review of results and their own experience since 1994 when duodenum sparing operations were introduced. Indications for surgical treatment were based on the diagnosis by US, CT and ERCP, in exceptional cases MR, after evaluation by a pancreatologist, roentgenologist and surgeon. The group of patients with chronic pancreatitis was extended by 15 patients from a group operated because of preoperative suspicion of a malignant pancreatic tumour not confirmed during and after surgery. In those Whipple's operation was performed. The same operation was performed in three patients with chronic pancreatitis with serious changes in the area of the head of the pancreas. In 111 patients a drainage and duodenum sparing operation was performed. Of these in 46x according to Neger, 9x according to Frey, 10x modification of these operations, 37x Partington-Rochelle's procedure.

    The First Surgical Clinic of the First Medical Faculty of Charles University and General Faculty Hospital in Prague made operations of the pancreas ever since 1971. In the work sooner or later all approaches to surgical treatment pancreatitis were reflected. The authors present a brief review of results and their own experience since 1994 when duodenum-sparing operations were introduced. Indications for surgical treatment were based on the diagnosis by US, CT and ERCP, in exceptional case MR, after evaluation by a pancreatologist, roentgenologist and surgeon. The group of patients with chronic pancreatitis was extended by 21 patients from a group operated because of preoperative suspicion of a malignant pancreatic tumour not confirmed during and after surgery. In those Whipple's operation was preformed. The same operation was performed in three patients with chronic pancreatitis with serious changes in the area of the head of the pancreas. In 123 patients a drainage and duodenum sparing operation was preformed, of these in 57 according to Beger, 19 according to Frey, 37 Partington-Rochelle's procedure. The authors record two sepsis postoperative complications after the classical Beger operation and the hospital stay was on average by five days shorter as compared with the classical method of Whipple. When evaluating postoperative complaints and problems (pain, malnutrition, physical constitution and social position) the authors recorded equally favourable results as after non-complicated duodenopancreatectomy. They varied, depending on the patients co-operation round 84-87% while authors consider Beger's operation logical because of the removal of the main tissue mass of the head of the pancreas, responsible for pain, complications caused by fibrosis in the area round the bile duct and duodenum, responsible for the deteriation of the compartment syndrome in the left half of the gland. Its result is destruction of the remainder of exocrine and endocrine tissue. Of

    Placebo response in the clinical trial setting is poorly understood and alleged to be driven by statistical confounds, and its biological underpinnings are questioned. Here we identified and validated that clinical placebo response is predictable from resting-state functional magnetic-resonance-imaging (fMRI) brain connectivity. This also led to discovering a brain region predicting active drug response and demonstrating the adverse effect of active drug interfering with placebo analgesia. Chronic knee osteoarthritis (OA) pain patients (n = 56) underwent pretreatment brain scans in two clinical trials. Study 1 (n = 17) was a 2-wk single-blinded placebo pill trial. Study 2 (n = 39) was a 3-mo double-blinded randomized trial comparing placebo pill to duloxetine. Study 3, which was conducted in additional knee OA pain patients (n = 42), was observational. fMRI-derived brain connectivity maps in study 1 were contrasted between placebo responders and nonresponders and compared to healthy controls (n = 20). Study 2 validated the primary biomarker and identified a brain region predicting drug response. In both studies, approximately half of the participants exhibited analgesia with placebo treatment. In study 1, right midfrontal gyrus connectivity best identified placebo responders. In study 2, the same measure identified placebo responders (95% correct) and predicted the magnitude of placebo’s effectiveness. By subtracting away linearly modeled placebo analgesia from duloxetine response, we uncovered in 6/19 participants a tendency of duloxetine enhancing predicted placebo response, while in another 6/19, we uncovered a tendency for duloxetine to diminish it. Moreover, the approach led to discovering that right parahippocampus gyrus connectivity predicts drug analgesia after correcting for modeled placebo-related analgesia. Our evidence is consistent with clinical placebo response having biological underpinnings and shows that the method can also reveal that active

    Full Text Available Abstract Background Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography and the benefit of its pharmacological treatment is unclear. Although prophylactic use of gabexate for the reduction of pancreatic injury after ERCP has been evaluated, the discrepancy about gabexate's beneficial effect on pancreatic injury still exists. This study aimed to evaluate the effectiveness and safety of gabexate in the prophylaxis of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP. Methods We employed the method recommended by the Cochrane Collaboration to perform a meta-analysis of randomized controlled trials (RCTs of gabexate in the prevention of post-ERCP pancreatitis (PEP including three RCTs conducted in Italy and one in China. Results All of the four RCTs were of high quality. When the RCTs were analyzed, odds ratios (OR for gabexate mesilate were 0.67 [95% CI (0.31~1.47, p = 0.32] for PEP, 3.78 [95% CI (0.62~22.98, p = 0.15] for severe PEP, 0.68 [95% CI (0.19~2.43, p = 0.56] for the case-fatality of PEP, 0.88 [95% CI (0.72~1.07, p = 0.20] for post-ERCP hyperamylasemia, 0.69 [95% CI (0.39~1.21, p = 0.19] for post-ERCP abdominal pain, thus indicating no beneficial effects of gabexate on acute pancreatitis, the death rate of PEP, hyperamylasemia and abdominal pain. No evidence of publication bias was found. Conclusion Gabexate mesilate can not prevent the pancreatic injury after ERCP. It is not recommended for the use of gabexate mesilate in the prophylaxis of PEP.

    A 75-year-old woman with epigastric pain was admitted to our emergency department. She was diagnosed with an acute exacerbation of chronic pancreatitis based on the results of blood tests and abdominal computed tomography (CT). The abdominal CT and magnetic resonance cholangiopancreatography revealed pancreas divisum. Abdominal CT also showed a stone in the minor papilla, with impaction of the stone being the most likely cause of the acute episode. Therefore, endoscopic sphincterotomy of the minor papilla and endoscopic naso-pancreatic duct drainage were performed to remove the stone and decrease the internal pressure of the pancreatic duct. These procedures improved the patient's clinical status. The naso-pancreatic drainage tube was removed, and her pancreatitis has not recurred. Herein, we report a rare case of an impacted minor papilla stone in a patient with pancreas divisum that caused an acute exacerbation of chronic pancreatitis.

    Full Text Available Objective Our aim was to investigate the relationship between imbalances of plasma amino acids and pain in chronic pancreatitis (CP. Methods Thirty patients with alcoholic CP in an exocrine-insufficient state were examined. We divided them between diet and control group. Diet group ingested 80g/300 kcal of the elemental diet "Elental®". This diet of 300 kcal/day was administered for two months. Selected clinical and laboratory values were compared between both groups before and after diet. Pain was observed and compared using a visual analog scale (VAS. Results There was no significant difference in the BMI between both groups before and after diet. The serum albumin level in diet group after diet was significantly higher than in control group (P=0.036. There was no significant difference in HbA1c between both groups before and after diet. The total amino acid concentration was significantly higher in diet group after diet than in control group (P=0.033. The concentrations of serum histidine and methionine in diet group after diet were significantly higher than in control group (histidine, P=0.022; methionine, P=0.026. The concentration of serum glutamate in diet group after diet was significantly lower than in control group (P=0.027. The balance of amino acids in diet group was normalized after the Elental® was ingested. The VAS score was significantly lower in diet group after diet than in control group (P=0.018. Conclusion These amino acid levels and pancreatic pain were improved by the elemental diet. The pancreatic pain may be related to these amino acid imbalances.

    Full Text Available Acute pancreatitis, an uncommon side effect of pegylated interferon α (PEG-IFN α and ribavirin (RBV combination therapy, has rarely been reported in the English language literature. Here, acute pancreatitis associated with PEG-IFN plus RBV treatment is described in three patients with chronic hepatitis C, genotype 1b with high serum hepatitis C virus RNA levels. The patients had been started on weekly subcutaneous injections of PEG-IFN α (60, 80, and 90 μg plus a daily oral dose of RBV (600 mg. The therapy was discontinued, however, because of the onset of acute pancreatitis (after 15 weeks, 48 weeks, and 3 weeks respectively. The drug-induced pancreatitis was diagnosed on the basis of elevated levels of amylase and lipase and the absence of other identifiable causes. High tumor necrosis factor-α was found in one patient and high interleukin-6 in the other two. The immune system stimulated by PEG-IFN and RBV combination therapy might have caused the acute pancreatitis. Further study is needed to clarify the mechanism of the onset of drug-induced pancreatitis by PEG-IFN and RBV combination therapy.

    慢性胰腺炎(chronic pancreatitis,CP)是由于胰腺炎症导致胰腺组织不可逆的毁损,最终将导致胰腺内、外分泌功能的部分或全部丧失.CP治疗目标是减轻疼痛,改善胰腺脂肪泻及营养不良,治疗糖尿病等并发症,保持或改善病人生活质量等.缓解疼痛是最常见的临床问题,补充胰酶和适当使用镇痛药物是常用治疗方法.胰酶制剂能显著改善脂肪泻,而其使用剂量和使用方法非常重要.近年来内镜治疗的进步令人鼓舞,方法包括胰腺括约肌切开术,支架置入术和体外震波碎石术等.内镜技术的进步为CP病人提供了新的治疗希望,但长期疗效仍有待随访.此外,在生活方式上,戒烟酒对CP病人很可能有益,而低脂饮食因为可能导致脂溶性维生素的缺乏而不被推荐.%Chronic pancreatitis (CP) is an ongoing inflamatory disorder characterized by irreversible destruction of the pancreas associated with disabling chronic pain and permanent loss of exocrine and endocrine function. The treatment of patients with CP revolves around control of pain, diabetes and steatorrhea. Pain relief is the most common and most difficult problem. The initial approach should consist of non-opioid analgesics and supplementation with pancreatic enzymes containing high amounts of proteases. Enzymes significantly reduce fat excretion and stool frequency and improve fat absorption. Dosing and timing are important. Although the medical treatment of CP is frustrating in most cases and the role of pancreatic enzyme replacement therapy and anti-oxidants is uncertain,the benefit of pancreatic endotherapy for CP is encouraging. The modalities includepancreatic sphincterotomy, stenting and ESWL to break large calculi. With growing expertise in endoscopic techniques, refinements in equipment and promising results from uncontrolled studies, patients should be offered opportunities of endoscopic therapy before subjecting them to surgical treatment

  15. Clinical trials in CIDP and chronic autoimmune demyelinating polyneuropathies.

    The main chronic autoimmune neuropathies include chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy (MMN), and anti-myelin-associated glycoprotein (MAG) demyelinating neuropathy. On the basis of randomized controlled studies, corticosteroids, intravenous immunoglobulin (IVIg), and plasmapheresis provide short-term benefits in CIDP. MMN responds only to IVIg. Because in MMN and CIDP, IVIg infusions are required every 3-6 weeks to sustain benefits or long-term remissions, there is a need for "IVIg-sparing" agents. In CIDP, immunosuppressive drugs, such as azathioprine, cyclosporine, methotrexate, mycophenolate, and cyclophosphamide, are used, but controlled trials have not shown that they are effective. Controlled trials have also not shown benefit to any agents in anti-MAG neuropathy. However, clinicians use many immunosuppressive drugs in both settings, but all have potentially serious side effects and are only effective in some patients. Thus, there is a need for new therapies in the inflammatory and paraproteinemic neuropathies. New agents targeting T cells, B cells, and transmigration and transduction molecules are discussed as potential treatment options for new trials. The need for biomarkers that predict therapeutic responses or identify patients with active disease is emphasized, and the search for better scoring tools that capture meaningful changes after response to therapies is highlighted.

    A pseudoaneurysm is an uncommon but important life threatening complication of chronic pancreatitis. The arteries most commonly affected by a pseudoaneurysm are (in decreasing percent occurrence), the splenic (40%), gastroduodenal (30%), pancreaticoduodenal (20%), gastric (5%), hepatic (2%), and others (superior mesenteric, jejunal, ileocecal, and aorta) (1-3%). Thrombosis of the splenic or portal vein is another important complication of chronic pancreatitis. In this case report, we present a rare complication in the form of a right hepatic artery pseudoaneurysm which developed within the thrombosed right portal vein of a 35-year-old woman afflicted with chronic pancreatitis.

    A 41-year old alchoholic male with a history of chronic pancreatitis was admitted for nausea, vomiting and weight loss. Angiogram was performed and demonstrated an aneurysmal sac with a narrow neck originating from the inferior aspect of the distal portion of the proper hepatic artery. The origin of the pseudoaneurysm was covered with a 5 mm × 2.5 cm Viabahn cover stent (Gore). A repeat angiogram showed some leak and a second stent (6 mm × 2.3 cm)was deployed and overlapped with the first stent by 3 mm. Contrast was injected and a repeat angiogram demonstrated complete exclusion of the aneurysm. A repeat computerized axial tomography (CAT) scan of the abdomen after 24 h showed successful stenting. The patient had an uneventful post-operative course.

    AIM: To compare the effects of neurolytic celiac plexus block (NCPB) and videothoracoscopic splanchnicectomy (VSPL) on pain and quality of life of chronic pancreatitis (CP) patients.METHODS: Forty-eight small duct CP patients were treated invasively with NCPB (n = 30) or VSPL (n = 18) in two non-randomized, prospective, case-controlled protocols due to chronic pain syndrome, and compared to a control group who were treated conservatively (n = 32). Visual analog scales were used to assess pain and opioid consumption rate was evaluated. In addition, the quality of life was measured using QLQ C-30 for NCPB and FACIT for VSPL.Although both questionnaires covered similar problems,they could not be compared directly one with another.Therefore, the studies were compared by meta-analysis methodology.RESULTS: Both procedures resulted in a significant positive effect on pain of CP patients. Opioids were withdrawn totally in 47.0% of NCPB and 36.4% of VSPL patients,and reduced in 53.0% and 45.4% of the respective patient groups. No reduction in opioid usage was observed in the control group. In addition, fatigue and emotional well-being showed improvements. Finally, NCPB demonstrated stronger positive effects on social support, which might possibly be attributed to earlier presentation of patients treated with NCPB.CONCLUSION: Both invasive pain treatment methods are effective in CP patients with chronic pain.

    Chronic pancreatitis (CP) is a progressive inflammation of pancreas characterized by irreversible morphologic change and dysfunction. Patients with chronic pancreatitis often present with abdominal pain, diarrhoea, jaundice, weight loss and the development of diabetes. Polysaccharides of Ganoderma lucidum strain S3 (GLPS3) possess antioxidative and immunomodulatory activities. This study was to characterize chemical structures of GLPS3 and determine their effects on diethyldithiocarbamate (DDC)-induced CP in mice. The total sugar content of GLPS3 from fermentation broth (GLPS3-Ⅰ), cultured mycelia (GLPS3-Ⅱ) and fruiting body (GLPS3-Ⅲ) was 90.4%, 92.2% and 91.8% respectively. GLPS3-Ⅰ, GLPS3-Ⅱ and GLPS3-Ⅲ were composed of Glu:Gal:Ara:Xyl, Glu:Gal:Ara:Xyl:Man:Rha, and Glu:Gal:Xyl:Man:Rha:Fuc, with molar ratio of 2.82: 1.33: 1.26: 0.87, 5.84: 2.23: 0.72:1.38: 1.40: 0.51 and 5.34: 2.72: 1.14: 1.10: 0.33: 0.38, respectively. The antioxidative activity of GLPS3-Ⅱfrom cultured mycelia in vitro is higher than other two polysaccharides. The superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in serum were increased while the malondialdehyde (MDA) levels were reversely decreased by GLPS3 treatment. Serum amylase (AMS) and lactic dehydrogenase (LDH) changes indicated the therapeutic effects of GLPS3. Moreover, interleukin-1beta (IL-1β) and interferon-gamma (INF-γ) contents were reduced most by GLPS3-Ⅱ. The results revealed that GLPS3 especially GLPS3-Ⅱfrom cultured mycelia were effective for CP therapy and bioactivity difference might be attributed to monosaccharide composition.

    Full Text Available The pathogenesis of idiopathic chronic pancreatitis remains poorly understood despite the high expectations for ascribing the pancreatic damage in affected patients to genetic defects. Mutations in the cationic trypsinogen gene, pancreatic secretory trypsin inhibitor, and the cystic fibrosis conductance regulator gene do not account for the chronic pancreatitis noted in most patients with idiopathic chronic pancreatitis. Small duct chronic pancreatitis can be best diagnosed with a hormone stimulation test. Endoscopic ultrasonography can detect abnormalities in both the parenchyma and ducts of the pancreas. The true value of endoscopic ultrasonography in diagnosing small duct chronic pancreatitis remains to be fully defined and is under active investigation. It is not clear whether endoscopic ultrasonography is more sensitive for early structural changes in patients with small duct disease or is over diagnosing chronic pancreatitis. Pancreatic enzyme supplementation with non-enteric formulation along with acid suppression (H2 blockers or proton pump inhibitors is an effective therapy for pain in patients with small duct chronic pancreatitis. The role of endoscopic ultrasonography-guided celiac plexus block should be limited to treating those patients with chronic pancreatitis whose pain has not responded to other modalities. Total pancreatectomy followed by autologous islet cell autotransplantation appears to be potential therapeutic approach but for now should be considered experimental.La patogenia de la pancreatitis crónica idiopática sigue siendo poco conocida, a pesar de las expectativas de atribuir el daño pancreático que sufren los pacientes con esta enfermedad a factores genéticos.

    A retrospective analysis of ultrasonograms of 24 patients with acute pancreatitis and 8 patients with chronic pancreatitis was performed. Nine cases were proven by surgery and 23 cases were diagnosed clinically. Generalized pancreatic enlargement with normal or decreased echogenecity was principal findings in acute pancreatitis, while pancreas was normal in size and echogenecity was normal or slightly altered in chronic pancreatitis. Ultrasonography is considered a simple and accurate method in the diagnosis of acute pancreatitis and thus it could be an initial test in patients with suspected acute pancreatitis.

    Hereditary pancreatitis is an autosomal dominant condition,which results in recurrent attacks of acute pancreatitis,progressing to chronic pancreatitis often at a young age.The majority of patients with hereditary pancreatitis expressone of two mutations (R122H or N29I) in the cationictrypsinogen gene (PRSS1 gene). It has been hypothesisedthat one of these mutations, the R122H mutation causespancreatitis by altering a trypsin recognition site sopreventing deactivation of trypsin within the pancreas andprolonging its action, resulting in autodigestion. Families withthese two mutations have been identified in many countriesand there are also other rarer mutations, which have alsobeen linked to hereditary pancreatitis.Patients with hereditary pancreatitis present in the sameway as those with sporadic pancreatitis but at an earlierage. It is common for patients to remain undiagnosed formany years, particularly ifthey present with non-specificsymptoms. Hereditary pancreatitis should always beconsidered in patients who present with recurrent pancreatitiswith a family history of pancreatic disease. If patients withthe 2 common mutations are compared, those with theR122H mutation are more likely to present at a younger ageand are more likely to require surgical intervention than thosewith N29I. Hereditary pancreatitis carries a 40 % lifetimerisk of pancreatic cancer with those patients aged between50 to 70 being most at risk in whom screening tests maybecome important.

    Full Text Available OBJECTIVE: Chronic low back pain represents a substantial cost to employers through benefits coverage and days missed due to incapacity. We sought to explore the effectiveness of Naturopathic care on chronic low back pain. METHODS: This study was a randomized clinical trial. We randomized 75 postal employees with low back pain of longer than six weeks duration to receive Naturopathic care (n = 39 or standardized physiotherapy (n = 36 over a period of 12 weeks. The study was conducted in clinics on-site in postal outlets. Participants in the Naturopathic care group received dietary counseling, deep breathing relaxation techniques and acupuncture. The control intervention received education and instruction on physiotherapy exercises using an approved education booklet. We measured low back pain using the Oswestry disability questionnaire as the primary outcome measure, and quality of life using the SF-36 in addition to low back range of motion, weight loss, and Body Mass Index as secondary outcomes. RESULTS: Sixty-nine participants (92% completed eight weeks or greater of the trial. Participants in the Naturopathic care group reported significantly lower back pain (-6.89, 95% CI. -9.23 to -3.54, p = <0.0001 as measured by the Oswestry questionnaire. Quality of life was also significantly improved in the group receiving Naturopathic care in all domains except for vitality. Differences for the aggregate physical component of the SF-36 was 8.47 (95% CI, 5.05 to 11.87, p = <0.0001 and for the aggregate mental component was 7.0 (95% CI, 2.25 to 11.75, p = 0.0045. All secondary outcomes were also significantly improved in the group receiving Naturopathic care: spinal flexion (p<0.0001, weight-loss (p = 0.0052 and Body Mass Index (-0.52, 95% CI, -0.96 to -0.08, p = 0.01. CONCLUSIONS: Naturopathic care provided significantly greater improvement than physiotherapy advice for patients with chronic low back pain. TRIAL REGISTRATION: Controlled-Trials

    Full Text Available Abstract Background Mechanisms underlying pain in chronic pancreatitis (CP are incompletely understood. Our previous data showed that astrocytes were actively involved. However, it was unclear how astrocytic activation was induced in CP conditions. In the present study, we hypothesized that toll-like receptors (TLRs were involved in astrocytic activation and pain behavior in CP-induced pain. Results To test our hypothesis, we first investigated the changes of TLR2-4 in the rat CP model induced by intrapancreatic infusion of trinitrobenzene sulfonic acid (TNBS. Western blot showed that after TNBS infusion, TLR3, but not TLR2 or TLR4, was increased gradually and maintained at a very high level for up to 5 w, which correlated with the changing course of mechanical allodynia. Double immunostaining suggested that TLR3 was highly expressed on astrocytes. Infusion with TLR3 antisense oligodeoxynucleotide (ASO dose-dependently attenuated CP-induced allodynia. CP-induced astrocytic activation in the spinal cord was also significantly suppressed by TLR3 ASO. Furthermore, real-time PCR showed that IL-1β, TNF-α, IL-6 and monocyte chemotactic protein-1 (MCP-1 were significantly increased in spinal cord of pancreatic rats. In addition, TLR3 ASO significantly attenuated CP-induced up-regulation of IL-1β and MCP-1. Conclusions These results suggest a probable "TLR3-astrocytes-IL-1β/MCP-1" pathway as a positive feedback loop in the spinal dorsal horn in CP conditions. TLR3-mediated neuroimmune interactions could be new targets for treating persistent pain in CP patients.

    Experimental evidence suggests that vitamin D has anticarcinogenic properties; however, a nested case-control study conducted in a population of male Finnish smokers found that higher 25-hydroxyvitamin D [25(OH)D], the best indicator of vitamin D status as determined by the sun and diet, was associated with a significant 3-fold increased risk for pancreatic cancer. We conducted a nested case-control study in the Prostate, Lung, Colorectal, and Ovarian Screening Trial cohort of men and women 55 to 74 years of age at baseline to test whether prediagnostic serum 25(OH)D concentrations were associated with pancreatic cancer risk. Between 1994 and 2006, 184 incident cases of pancreatic adenocarcinoma occurred (follow-up to 11.7 years). Two controls (n = 368) who were alive at the time the case was diagnosed were selected for each case and matched by age, race, sex, and calendar date of blood draw (to control for seasonal variation). We calculated odds ratios (OR) and 95% confidence intervals (95% CI) using conditional logistic regression, adjusting for smoking and body mass index. Vitamin D concentrations were not associated with pancreatic cancer overall (highest versus lowest quintile, >82.3 versus <45.9 nmol/L: OR, 1.45; 95% CI, 0.66-3.15; P trend = 0.49). However, positive associations were observed among subjects with low estimated annual residential solar UBV exposure, but not among those with moderate to high annual exposure (P interaction = 0.015). We did not confirm the previous strong positive association between 25(OH)D and pancreatic cancer; however, the increased risk among participants with low residential UVB exposure is similar.

    Full Text Available BACKGROUND: Pancreatic beta-cell ATP-sensitive potassium (K ATP channels are critical links between nutrient metabolism and insulin secretion. In humans, reduced or absent beta-cell K ATP channel activity resulting from loss-of-function K ATP mutations induces insulin hypersecretion. Mice with reduced K ATP channel activity also demonstrate hyperinsulinism, but mice with complete loss of K ATP channels (K ATP knockout mice show an unexpected insulin undersecretory phenotype. Therefore we have proposed an "inverse U" hypothesis to explain the response to enhanced excitability, in which excessive hyperexcitability drives beta-cells to insulin secretory failure without cell death. Many patients with type 2 diabetes treated with antidiabetic sulfonylureas (which inhibit K ATP activity and thereby enhance insulin secretion show long-term insulin secretory failure, which we further suggest might reflect a similar progression. METHODS AND FINDINGS: To test the above hypotheses, and to mechanistically investigate the consequences of prolonged hyperexcitability in vivo, we used a novel approach of implanting mice with slow-release sulfonylurea (glibenclamide pellets, to chronically inhibit beta-cell K ATP channels. Glibenclamide-implanted wild-type mice became progressively and consistently diabetic, with significantly (p < 0.05 reduced insulin secretion in response to glucose. After 1 wk of treatment, these mice were as glucose intolerant as adult K ATP knockout mice, and reduction of secretory capacity in freshly isolated islets from implanted animals was as significant (p < 0.05 as those from K ATP knockout animals. However, secretory capacity was fully restored in islets from sulfonylurea-treated mice within hours of drug washout and in vivo within 1 mo after glibenclamide treatment was terminated. Pancreatic immunostaining showed normal islet size and alpha-/beta-cell distribution within the islet, and TUNEL staining showed no evidence of apoptosis

    Although certain risk factors can identify individuals who are most likely to develop chronic pain, few interventions to prevent chronic pain have been identified. To facilitate the identification of preventive interventions, an IMMPACT meeting was convened to discuss research design considerations for clinical trials investigating the prevention of chronic pain. We present general design considerations for prevention trials in populations that are at relatively high risk for developing chronic pain. Specific design considerations included subject identification, timing and duration of treatment, outcomes, timing of assessment, and adjusting for risk factors in the analyses. We provide a detailed examination of 4 models of chronic pain prevention (ie, chronic postsurgical pain, postherpetic neuralgia, chronic low back pain, and painful chemotherapy-induced peripheral neuropathy). The issues discussed can, in many instances, be extrapolated to other chronic pain conditions. These examples were selected because they are representative models of primary and secondary prevention, reflect persistent pain resulting from multiple insults (ie, surgery, viral infection, injury, and toxic or noxious element exposure), and are chronically painful conditions that are treated with a range of interventions. Improvements in the design of chronic pain prevention trials could improve assay sensitivity and thus accelerate the identification of efficacious interventions. Such interventions would have the potential to reduce the prevalence of chronic pain in the population. Additionally, standardization of outcomes in prevention clinical trials will facilitate meta-analyses and systematic reviews and improve detection of preventive strategies emerging from clinical trials.

    This study aimed to investigate the occurrence of and determine the risk factors for steatorrhea in chronic pancreatitis (CP). It was based on analysis of both retrospectively and prospectively acquired database for CP patients admitted to our center from January 2000 to December 2013. Demographic data, course of disease, medical history, and follow-up evaluations of patients were documented in detail. Cumulative rate of steatorrhea was calculated by using the Kaplan-Meier method. For risk factor analysis, multivariate analysis by Cox proportional hazards regression model was performed. A total of 2,153 CP patients were included with a mean follow-up duration of 9.3 years. Approximately 14% (291/2,153) of CP patients presented with steatorrhea at diagnosis of CP. Cumulative rates of steatorrhea at 1, 5, 10, and 20 years after diagnosis of CP were 4.27% (95% CI: 3.42%-5.34%), 12.53% (95% CI: 10.74%-14.59%), 20.44% (95% CI: 17.37%-23.98%) and 30.82% (95% CI: 20.20%-45.21%), respectively. Male gender (HR = 1.771, p = 0.004), diabetes (HR = 1.923, p alcohol abuse (HR = 1.503, p = 0.025) and pancreaticoduodenectomy (HR = 2.901, p diabetes, alcohol abuse and pancreaticoduodenectomy lead to increased risk of steatorrhea in CP patients.

    Intestinal dysbiosis and its functional implications in chronic pancreatitis (CP) have not been elaborately studied. We evaluated the taxonomic and functional alterations in intestinal microbiota in 30 well-characterised patients with CP (16 without, 14 with diabetes) and 10 healthy controls. The patients with CP and diabetes had significantly longer disease duration and greater degree of malnutrition. There was increase in plasma endotoxin concentrations from controls to CP non-diabetics to CP diabetics. We observed significant differences in richness and alpha diversity between the groups. We also observed increase in the Firmicutes:Bacteroidetes ratio in CP patients without and with diabetes. There was reduction in abundance of Faecalibacterium prausnitzii and Ruminococcus bromii from controls to CP non-diabetics to CP diabetics. On the other hand, there was increase in LPS (endotoxin) synthetic pathways (KEGG orthology) in the groups. Faecalibacterium prausnitzii abundance correlated negatively with plasma endotoxin and glycemic status; while plasma endotoxin correlated positively with blood glucose and negatively with plasma insulin. Our results have important implications for future studies exploring mechanistic insights on secondary diabetes in CP. PMID:28255158

    Background Evidence on small intestinal bacterial overgrowth (SIBO) in patients with chronic pancreatitis (CP) is conflicting. Aim The purpose of this study was to perform a systematic review and meta-analysis on the prevalence of SIBO in CP and to examine the relationship of SIBO with symptoms and nutritional status. Methods Case-control and cross-sectional studies investigating SIBO in CP patients were analysed. The prevalence of positive tests was pooled across studies, and the rate of positivity between CP cases and controls was calculated. Results In nine studies containing 336 CP patients, the pooled prevalence of SIBO was 36% (95% confidence interval (CI) 17–60%) with considerable heterogeneity (I2 = 91%). A sensitivity analysis excluding studies employing lactulose breath test gave a pooled prevalence of 21.7% (95% CI 12.7–34.5%) with lower heterogeneity (I2 = 56%). The odds ratio for a positive test in CP vs controls was 4.1 (95% CI 1.6–10.4) (I2 = 59.7%). The relationship between symptoms and SIBO in CP patients varied across studies, and the treatment of SIBO was associated with clinical improvement. Conclusions One-third of CP patients have SIBO, with a significantly increased risk over controls, although results are heterogeneous, and studies carry several limitations. The impact of SIBO and its treatment in CP patients deserve further investigation.

    We report the case of a patient suffering from idiopathic chronic pancreatitis (ICP) and compound heterozygous for mutations G542X and S1235R of the cystic fibrosis transmembrane regulator (CFTR) gene. The patient had normal sweat test and no other clinical sign usually linked with a typical or moderate pathology (bronchiectasis, nasal polyposis, congenital absence of the vas deferens) of the CFTR gene. G542X is a severe mutation, which is usually found in classical cystic fibrosis when associated with other severe mutations. S1235R is a quite rare abnormality recently reported as being potentially pathogenic when combined in trans with a second CF mutation. Our case is quite similar to the only other six patients in the literature in whom only the pancreas is affected and who bear a rare mutation with moderate effect. The history and the clinical features of our patient indicate an unambiguous isolated ICP in which the presence of the S1235R mutation--in trans with regard to G542X--is likely responsible for the ICP phenotype. This case could throw light on some of the as yet poorly known abnormalities of the CFTR gene in the ICP phenotype.

    Chronic inflammation may promote development of coronary heart disease. Studies on the relationship between chronic pancreatitis (CP) and cardiovascular diseases are scant.We conducted a nationwide retrospective cohort study to determine the risk of acute coronary syndrome (ACS) in patients with CP.We randomly selected a comparison cohort of individuals without CP from the Taiwan National Health Insurance Research Database (N = 23.74 million) and frequency-matched them with patients with CP from 2000 to 2010 in a 1:4 ratio according to age, sex, and index year. The follow-up period lasted from the index date of the new CP diagnosis to the date of ACS diagnosis, censoring, or the end of 2011. We analyzed the risk of ACS by using Cox proportional-hazard models.In total, 17,405 patients with CP and 69,620 individuals without CP were followed for 84,430 and 417,426 person-years. Most patients with CP were men, and the mean age of the patients was 48.3 ± 15.0 years. The overall ACS incidence was 2.15-fold higher in the CP cohort than in the non-CP cohort (4.89 vs 2.28 per 10,000 person-years) with an adjusted hazard ratio (aHR) of 1.40 (95% confidence interval [CI] 1.20-1.64). Compared with individuals without CP, patients with CP aged ≤39 years exhibited the highest risk of ACS (aHR 2.14, 95% CI 1.13-4.02), followed by those aged 40 to 54 years (aHR 1.66, 95% CI 1.23-2.24) and those aged 55 to 69 years (aHR 1.53, 95% CI 1.15-2.03).CP may become an independent risk factor for ACS.

    Full Text Available Inflammation is part of the body’s immune response in order to remove harmful stimuli – like pathogens, irritants or damaged cells - and start the healing process. Recurrent or chronic inflammation on the other side seems a predisposing factor for carcinogenesis and has been found associated with cancer development. In chronic pancreatitis mutations of the cationic trypsinogen (PRSS1 gene have been identified as risk factors of the disease. Hereditary pancreatitis is a rare cause of chronic pancreatic inflammation with an early onset, mostly during childhood. Hereditary pancreatitis often starts with recurrent episodes of acute pancreatitis and the clinical phenotype is not very much different from other etiologies of the disease. The long-lasting inflammation however generates a tumor promoting environment and represents a major risk factor for tumor development This review will reflect our knowledge concerning the specific risk of hereditary pancreatitis patients to develop pancreatic cancer.

    Mutation of Kirsten rat sarcoma viral oncogene homolog (KRAS) and chronic pancreatitis are the most common pathogenic events involved in human pancreatic carcinogenesis. In the process of long-standing chronic inflammation, aberrant metabolites of arachidonic acid play a crucial role in promoting carcinogenesis, in which the soluble epoxide hydrolase (sEH), as a pro-inflammatory enzyme, generally inactivates anti-inflammatory epoxyeicosatrienoic acids (EETs). Herein, we determined the effect of our newly-synthesized novel compound trans-4-{4-[3-(4-chloro-3-trifluoromethyl-phenyl)-ureido]-cyclohexyloxy}-pyridine-2-carboxylic acid methylamide (t-CUPM), a dual inhibitor of sEH and RAF1 proto-oncogene serine/threonine kinase (c-RAF), on inhibiting the development of pancreatitis and pancreatic intraepithelial neoplasia (mPanIN) in LSL-Kras(G12D)/Pdx1-Cre mice. The results showed that t-CUPM significantly reduced the severity of chronic pancreatitis, as measured by the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The progression of low-grade mPanIN I to high-grade mPanIN II/III was significantly suppressed. Inhibition of mutant Kras-transmitted phosphorylation of mitogen-activated protein kinase's kinase/extracellular signal-regulated kinases was demonstrated in pancreatic tissues by western blots. Quantitative real-time polymerase chain reaction analysis revealed that t-CUPM treatment significantly reduced the levels of inflammatory cytokines including tumor necrosis facor-α, monocyte chemoattractant protein-1, as well as vascular adhesion molecule-1, and the levels of Sonic hedgehog and Gli transcription factor (Hedgehog pathway). Analysis of the eicosanoid profile revealed a significant increase of the EETs/dihydroxyeicosatrienoic acids ratio, which further confirmed sEH inhibition by t-CUPM. These results indicate that simultaneous inhibition of sEH and c-RAF by t-CUPM is important in preventing chronic pancreatitis and carcinogenesis.

The effects of GLP-1 agonists on pancreatic endocrine cells are well studied; however, there is little information on effects on other pancreatic tissues that might be involved in inflammatory processes. Pancreatic stellate cells (PSCs) can have an important role in pancreatitis, secreting various inflammatory cytokines/chemokines, as well as collagen. In this study, we investigated GLP-1R occurrence in normal pancreas, acute pancreatitis (AP)/chronic pancreatitis (CP), and the effects of GLP-1 analog on normal PSCs, their ability to stimulate inflammatory mediator secretion or proliferation. GLP-1 receptor (GLP-1R) expression/localization in normal pancreas and pancreatitis (AP/CP) tissues were evaluated with histological/immunohistochemical analysis. PSCs were isolated from male Wistar rats. GLP-1R expression and effects of GLP-1 analog on activated PSCs was examined with real-time PCR, MTS assays and western blotting. In normal pancreas, pancreatic β cells expressed GLP-1R, with only low expression in acinar cells, whereas in AP or CP, acinar cells, ductal cells and activated PSCs expressed GLP-1R. With activation of normal PSCs, GLP-1R is markedly increased, as is multiple other incretin-related receptors. The GLP-1 analog, liraglutide, did not induce inflammatory genes expression in activated PSCs, but induced proliferation. Liraglutide activated multiple signaling cascades in PSCs, and the extracellular signal-regulated kinase pathway mediated the PSCs proliferation. GLP-1Rs are expressed in normal pancreas and there is marked enhanced expression in AP/CP. GLP-1-agonist induced cell proliferation of activated PSCs without increasing release of inflammatory mediators. These results suggest chronic treatment with GLP-1R agonists could lead to proliferation/chronic

    There has been an increase in the number of chronic pain clinical trials in which the treatments being evaluated did not differ significantly from placebo in the primary efficacy analyses despite previous research suggesting that efficacy could be expected. These findings could reflect a true lack of efficacy or methodological and other aspects of these trials that compromise the demonstration of efficacy. There is substantial variability among chronic pain clinical trials with respect to important research design considerations, and identifying and addressing any methodological weaknesses would enhance the likelihood of demonstrating the analgesic effects of new interventions. An IMMPACT consensus meeting was therefore convened to identify the critical research design considerations for confirmatory chronic pain trials and to make recommendations for their conduct. We present recommendations for the major components of confirmatory chronic pain clinical trials, including participant selection, trial phases and duration, treatment groups and dosing regimens, and types of trials. Increased attention to and research on the methodological aspects of confirmatory chronic pain clinical trials has the potential to enhance their assay sensitivity and ultimately provide more meaningful evaluations of treatments for chronic pain.

    AIM: Endoscopic metal stenting (EMS) offers good results in short to medium term follow-up for bile duct stenosis associated with chronic pancreatitis (CP);however, longer follow-up is needed to determine if EMS has the potential to become the treatment of first choice.METHODS: EMS was performed in eight patients with severe common bile duct stenosis due to CR After the resolution of cholestasis by endoscopic naso-biliary drainage three patients were subjected to EMS while,the other five underwent EMS following plastic tube stenting. The patients were followed up for more than5 years through periodical laboratory tests and imaging techniques.RESULTS: EMS was successfully performed in all the patients. Two patients died due to causes unrelated to the procedure: one with an acute myocardial infarction and the other with maxillary carcinoma at 2.8 and 5.5years after EMS, respectively. One patient died with cholangitis because of EMS clogging 3.6 years after EMS.None of these three patients had showed symptoms of cholestasis during the follow-up period. Two patients developed choledocholithiasis and two suffered from duodenal ulcers due to dislodgement of the stent between 4.8 and 7.3 years after stenting; however, they were successfully treated endoscopically. Thus, five of eight patients are alive at present after a mean follow-up period of 7.4 years.CONCLUSION: EMS is evidently one of the very promising treatment options for bile duct stenosis associated with CP, provided the patients are closely followed up; thus setting a system for their prompt management on emergency is desirable.

    AIM: To darify whether serum chemoldne and cytokine levels can become useful biological and functional markers to assess the severity of chronic pancreatitis (CP). This study aimed at darifying whether serum chemokine and cytokine levels can become useful biological and functional markers to assess the severity of CP. METHODS: Serum monocyte chemoattractant protein-1 (MCP-1), transforming growth factor beta-1 (TGF-β1), and soluble type fractalkine (s-fractalkine) concentrations were examined in patients with CP (n = 109) and healthy controls (n = 116). Severity of disease was classified in patients with CP by a staging system. Relationships between stage-specific various clinical factors and serum MCP-1, TGF-β1, and s-fractalkine levels were investigated. Furthermore, 57 patients with non-alcoholic CP were similarly evaluated in order to exclude influence of alcohol intake. RESULTS: Patients with CP showed significant higher levels of serum TGF-β1 and s-fractalkine, but not MCP-1, compared to the controls. Serum TGF-β1 in the severe stage and s-fractalkine in the mild and the severe stage of CP significantly increased compared to those of controls. However, it was observed that both TGF-β1 and s-fractalkine levels were affected by alcohol intake. In patients with non-alcoholic CP, serum TGF-β1 showed significant increase in the moderate stage of CP, and serum s-fractalkine revealed significant increase in the early stage of CP. CONCLUSION: It is suggested that the measurement of serum F-fractalkine is useful to diagnose early-stage CP. Moreover, the combined determination of both, s-fractalkine and TGF-β1, in human sera may be helpful in evaluating the severity status of CP.

    Full Text Available Context Heterotopic pancreas is usually an incidental finding during pathologic evaluation of gastrointestinal polyps or lesions encoun-tered during endoscopy for nonspecific symptoms or unrelated conditions. However, the same neoplastic processes that occur in normal pancreas also can occur in pancreatic heterotopias. Case report We report two cases of intraductal papillary mucinous neoplasms arising in pancreatic heterotopia within the duodenum of two patients. These cases are among the first reports of neoplasia occurring in pancre-atic heterotopia of the duodenum. Both patients are being managed expectantly, as there is currently no consensus regarding the proper follow up in these cases, particularly those that have been incompletely excised. Conclusion These cases highlight the potential for neo-plasia in pancreatic heterotopia and emphasize the importance of careful evaluation of these lesions. Close clinical follow up and possible excision may be warranted in patients with concerning pathologic or clinical findings.

    Pancreatitis is defined as the inflammation of the pancreas and considered the most common pancreatic disease in children and adults. Imaging plays a significant role in the diagnosis, severity assessment, recognition of complications and guiding therapeutic interventions. In the setting of pancreatitis, wider availability and good image quality make multi-detector contrastenhanced computed tomography(MD-CECT) the most used imaging technique. However, magnetic resonance imaging(MRI) offers diagnostic capabilities similar to those of CT, with additional intrinsic advantages including lack of ionizing radiation and exquisite soft tissue characterization. This article reviews the proposed definitions of revised Atlanta classification for acute pancreatitis, illustrates a wide range of morphologic pancreatic parenchymal and associated peripancreatic changes for different types of acute pancreatitis. It also describes the spectrum of early and late chronic pancreatitis imaging findings and illustrates some of the less common types of chronic pancreatitis, with special emphasis on the role of CT and MRI.

    Full Text Available Choric pancreatitis is an actual medical and psychological problem in Ukraine. The aim of the work was to study the features of coping in patients with chronic pancreatitis of alcoholic and biliary etiology.Methods. For detecting coping-mechanisms the standard method WCQ Р of Lazarus was used. The study of addictive tendencies was carried out with the help of questionnaire AUDIT and UDIT-tests oriented on patterns of dependent behavior.Results. The study of features of coping-mechanisms and an addiction to dependent behavior in patients with chronic pancreatitis revealed intergroup and intragroup differences. Confrontation and low levels of self-control, responsibility and positive assessment were intrinsic for respondents with alcoholic etiology of pancreatitis. Women demonstrated the high addiction to the search of social support, men – to distancing. As to an addictive behavior there was revealed that the typical common tendencies were the consumption of coffee, alcohol, internet-dependence, the specific ones for women – TV, shopping-dependencies, for men – workaholism in patients with biliary and computer-addiction in patients with alcoholic chronic pancreatitis. Intergroup differences were demonstrated by an addiction to disorder of food behavior in patients with biliary and consumption of alcohol and smoking in respondents with alcoholic etiology of pancreatitis.Conclusions. The revealed differences in coping-strategies of patients with different nosological forms of chronic pancreatitis give important information for detecting the targets of medical and psychological influence and constructing of differentiated program of medical and psychological help to patients of this type

    Objectives To systematically assess registration details of ongoing randomised controlled trials (RCTs) targeting 10 common chronic conditions and registered at ClinicalTrials.gov and to determine the prevalence of (1) trial records excluding patients with concomitant chronic condition(s) and (2) those specifically targeting patients with concomitant chronic conditions. Design Systematic review of trial registration records. Data sources ClinicalTrials.gov register. Study selection All ongoing RCTs registered from 1 January 2014 to 31 January 2015 that assessed an intervention targeting adults with coronary heart disease (CHD), hypertension, heart failure, stroke/transient ischaemic attack, atrial fibrillation, type 2 diabetes, chronic obstructive pulmonary disease, painful condition, depression and dementia with a target sample size ≥100. Data extraction From the trial registration records, 2 researchers independently recorded the trial characteristics and the number of exclusion criteria and determined whether patients with concomitant chronic conditions were excluded or specifically targeted. Results Among 319 ongoing RCTs, despite the high prevalence of the concomitant chronic conditions, patients with these conditions were excluded in 251 trials (79%). For example, although 91% of patients with CHD had a concomitant chronic condition, 69% of trials targeting such patients excluded patients with concomitant chronic condition(s). When considering the co-occurrence of 2 chronic conditions, 31% of patients with chronic pain also had depression, but 58% of the trials targeting patients with chronic pain excluded patients with depression. Only 37 trials (12%) assessed interventions specifically targeting patients with concomitant chronic conditions; 31 (84%) excluded patients with concomitant chronic condition(s). Conclusions Despite widespread multimorbidity, more than three-quarters of ongoing trials assessing interventions for patients with chronic conditions

    Acute pancreatitis is an inflammatory disease characterized by interstitial edema, inflammatory cell infiltration, and acinar cell necrosis, depending on its severity. Regardless of the extent of tissue injury, acute pancreatitis is a completely reversible process with evident normal tissue architecture after recovery. Its pathogenic mechanism has been known to be closely related to intracellular digestive enzyme activation. In contrast to acute pancreatitis, chronic pancreatitis is character...

    Autoimmune pancreatitis is a relatively rare form of chronic pancreatitis which is characterized by a lymphoplasmatic infiltrate with a storiform fibrosis and often goes along with painless jaundice and discrete discomfort of the upper abdomen. Clinically we distinguish between two subtypes, which differ in terms of their histology, clinical picture and prognosis. Type 1 autoimmune pancreatitis is the pancreatic manifestation of the IgG4-associated syndrome which also involves other organs. About one third of the patients can only be diagnosed after either histological prove or a successful steroid trail. Type 2 is IgG4-negative with the histological picture of an idiopathic duct centric pancreatitis and is to higher degree associated with inflammatory bowel disease. A definitive diagnosis can only be made using biopsy. Usually both forms show response to steroid treatment, but in type 1 up to 50 % of the patients might develop a relapse. The biggest challenge and most important differential diagnosis remains the discrimination of AIP from pancreatic cancer, because also AIP can cause mass of the pancreatic head, lymphadenopathy and ductal obstruction. This article summarizes recent advances on epidemiology, clinical presentation, diagnostic strategy, therapy and differential diagnosis in this relatively unknown disease.

    Full Text Available The most common cause of chronic pancreatitis (CP is alcohol abuse. The aim of the present study was to identify patients with genetic predisposition to CP abusing alcohol. The question posed was whether CP manifests at a younger age and diabetes mellitus develops earlier in individuals with genetic predisposition. The study encompassed 79 patients with alcoholic chronic pancreatitis (ACP and control group (100 persons. The following mutations were determined: R122H and N29I of PRSS1 and N34S of SPINK1 as well as E366K and E288V of SERPINA 1. No R122H and N291 mutations were observed in the group of ACP patients and in controls. Moreover, there was no E288V mutation. In 79 ACP patients, six SPINK 1 (N34S/wt mutations were observed. In the control group, one heterozygous SPINK 1N34S gene mutation was found (P=0.0238. Two PiZ mutations were identified in patients with ACP and one analogical mutation in controls. Amongst patients with ACP as well as SPINK1 and PiZ mutations, the onset of disease was observed earlier and developed earlier. The prevalence of SPINK1 mutation is higher in patients with ACP than in healthy populations. This mutation together with the effects of alcohol accelerates the development of ACP and of diabetes mellitus.

    Exocrine pancreatic digestive enzymes are essential for the digestion of dietary components and are regulated by them. Chronic excess dietary high fat (HF) consumption is a contributing factor of diet-induced obesity (DIO) and associated chronic diseases and requires adaptation by the pancreas. The aim of the present study was to investigate the effects of chronic HF diet feeding on exocrine pancreatic digestive enzyme transcript levels in DIO C57BL/6J mice. C57BL/6J mice were fed diets containing either 10 or 45% energy (E%) derived from fat for 12 weeks (n 10 mice per diet group). Pancreatic tissue and blood samples were collected at 0, 4 and 12 weeks. The expression of a panel of exocrine pancreatic digestive enzymes was analysed using quantitative RT-PCR and Western blot analysis. The HF (45 E%) diet-fed C57BL/6J mice developed obesity, hyperleptinaemia, hyperglycaemia and hyperinsulinaemia. The transcript levels of pancreatic lipase (PL), pancreatic lipase-related protein 2 (PLRP2) and pancreatic phospholipase A2 (PLA2) were initially elevated; however, they were down-regulated to basal control levels at week 12. The transcript levels of colipase were significantly affected by diet and time. The protein levels of PL and PLRP2 responded to HF diet feeding. The transcript levels of amylase and proteases were not significantly affected by diet and time. The transcript levels of specific lipases in hyperinsulinaemic, hyperleptinaemic and hyperglycaemic DIO C57BL/6J mice are down-regulated. However, these mice compensate for this by the post-transcriptional regulation of the levels of proteins that respond to dietary fat. This suggests a complex regulatory mechanism involved in the modulation of fat digestion.

    The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori infection and chronic corpus atrophic gastritis. Conditional logistic regression models were applied to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs), adjusted for matching factors and other potential confounders. Our results showed that pancreatic cancer risk was neither associated with H. pylori seropositivity (OR = 0.96; 95% CI: 0.70, 1.31) nor CagA seropositivity (OR = 1.07; 95% CI: 0.77, 1.48). We also did not find any excess risk among individuals seropositive for H. pylori but seronegative for CagA, compared with the group seronegative for both antibodies (OR = 0.94; 95% CI: 0.63, 1.38). However, we found that chronic corpus atrophic gastritis was non-significantly associated with an increased pancreatic cancer risk (OR = 1.35; 95% CI: 0.77, 2.37), and although based on small numbers, the excess risk was particularly marked among individuals seronegative for both H. pylori and CagA (OR = 5.66; 95% CI: 1.59, 20.19, p value for interaction < 0.01). Our findings provided evidence supporting the null association between H. pylori infection and pancreatic cancer risk in western European populations. However, the suggested association between chronic corpus atrophic gastritis and pancreatic cancer risk warrants independent verification in future studies, and, if confirmed, further studies on the underlying mechanisms.

  7. Pancreas divisum and duodenal diverticula as two causes of acute or chronic pancreatitis that should not be overlooked: a case report

    Directory of Open Access Journals (Sweden)

    De Filippo Massimo

    2008-05-01

    Full Text Available Abstract Introduction Pancreas divisum is a congenital anatomical anomaly characterized by the lack of fusion of the ventral and dorsal parts of the pancreas during the eighth week of fetal development. This condition is found in 5% to 14% of the general population. In pancreas divisum, the increased incidence of acute and chronic pancreatitis is caused by inadequate drainage of secretions from the body, tail and part of the pancreatic head through an orifice that is too small. The incidence of diverticula in the second part of the duodenum is found in approximately 20% of the population. Compression of the duodenal diverticula at the end of the common bile duct leads to the formation of biliary lithiasis (a principal cause of acute pancreatitis, pain associated with biliary lithiasis owing to compression of the common bile duct (at times with jaundice, and compression of the last part of Wirsung's duct or the hepatopancreatic ampulla (ampulla of Vater that may lead to both acute and chronic pancreatitis. Case presentation We describe the radiological findings of the case of a 75-year-old man with recurrent acute pancreatitis due to a combination of pancreas divisum and duodenal diverticula. Conclusion Magnetic resonance cholangiopancreatography is advisable in patients with recurrent pancreatitis (both acute and chronic since it is the most appropriate noninvasive treatment for the study of the pancreatic system (and the eventual presence of pancreas divisum and the biliary systems (eventual presence of biliary microlithiasis. Moreover, it can lead to the diagnostic suspicion of duodenal diverticula, which can be confirmed through duodenography with X-ray or computed tomography scan with a radio-opaque contrast agent administered orally.

  8. Endoscopic pancreatic duct stent placement for inflammatory pancreatic diseases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The role of endoscopic therapy in the management of pancreatic diseases is continuously evolving; at present most pathological conditions of the pancreas are successfully treated by endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic ultrasound (EUS),or both. Endoscopic placement of stents has played and still plays a major role in the treatment of chronic pancreatitis, pseudocysts, pancreas divisum, main pancreatic duct injuries, pancreatic fistulae, complications of acute pancreatitis, recurrent idiopathic pancreatitis,and in the prevention of post-ERCP pancreatitis. These stents are currently routinely placed to reduce intraductal hypertension, bypass obstructing stones, restore lumen patency in cases with dominant, symptomatic strictures,seal main pancreatic duct disruption, drain pseudocysts or fluid collections, treat symptomatic major or minor papilla sphincter stenosis, and prevent procedure-induced acute pancreatitis. The present review aims at updating and discussing techniques, indications, and results of endoscopic pancreatic duct stent placement in acute and chronic inflammatory diseases of the pancreas.

    Pancreatitis is inflammation of pancreas and caused by a number of factors including pancreatic duct obstruction, alcoholism, and mutation in the cationic trypsinogen gene. Pancreatitis is represented as acute pancreatitis with acute inflammatory responses and; chronic pancreatitis characterized by marked stroma formation with a high number of infiltrating granulocytes (such as neutrophils, eosinophils), monocytes, macrophages and pancreatic stellate cells (PSCs). These inflammatory cells are known to play a central role in initiating and promoting inflammation including pancreatic fibrosis, i.e., a major risk factor for pancreatic cancer. A number of inflammatory cytokines are known to involve in promoting pancreatic pathogenesis that lead pancreatic fibrosis. Pancreatic fibrosis is a dynamic phenomenon that requires an intricate network of several autocrine and paracrine signaling pathways. In this review, we have provided the details of various cytokines and molecular mechanistic pathways (i.e., Transforming growth factor-β/SMAD, mitogen-activated protein kinases, Rho kinase, Janus kinase/signal transducers and activators, and phosphatidylinositol 3 kinase) that have a critical role in the activation of PSCs to promote chronic pancreatitis and trigger the phenomenon of pancreatic fibrogenesis. In this review of literature, we discuss the involvement of several pro-inflammatory and anti-inflammatory cytokines, such as in interleukin (IL)-1, IL-1β, IL-6, IL-8 IL-10, IL-18, IL-33 and tumor necrosis factor-α, in the pathogenesis of disease. Our review also highlights the significance of several experimental animal models that have an important role in dissecting the mechanistic pathways operating in the development of chronic pancreatitis, including pancreatic fibrosis. Additionally, we provided several intermediary molecules that are involved in major signaling pathways that might provide target molecules for future therapeutic treatment strategies for

Methods Following resection of pancreatic adenocarcinoma patients were randomized to pre and post CRT 5-FU vs. pre and post CRT G. 5-FU = continuous (CI) at 250 mg/m2/day. G = 1000 mg/m2 weekly; both given over 3 weeks pre and 12 weeks post - CRT. CRT = 50.4 Gy with CI 5-FU. Primary endpoint was survival for all patients and for pancreatic head tumor patients. Results Four hundred and fifty-one patients were eligible. Univariate analysis showed no difference in OS. Pancreatic head tumor patients (n=388) had a median survival and 5-year OS of 20.5 months and 22% with G vs. 17.1 months and 18% with 5-FU. On multivariate analysis, patients on the G arm with pancreatic head tumors experienced a trend towards improved OS (p=0.08). First site of relapse local recurrence in 28% of patients vs. distant relapse in 73%. Conclusion(s) The sequencing of 5-FU CRT with G as done in this trial is not associated with a statistically significant improvement in OS. Despite local recurrence being approximately half of that reported in previous adjuvant trials, distant disease relapse still occurs in ≥ 70% of patients. These findings serve as the basis for the recently activated EORTC/US Intergroup RTOG 0848 phase III adjuvant trial evaluating the impact of CRT after completion of a full course of G. PMID:21499862

    Background and objectives Increased water intake may benefit kidney function. Prior to initiating a larger randomised controlled trial (RCT), we examined the safety and feasibility of asking adults with chronic kidney disease (CKD) to increase their water intake. Design, setting, participants and measurements Beginning in October 2012, we randomly assigned 29 adults with stage 3 CKD (estimated glomerular filtration rate (eGFR) 30–60 mL/min/1.73 m2 and albuminuria) to one of the two groups of water intake: hydration (n=18) or standard (n=11). We asked the hydration group to increase their water intake by 1.0–1.5 L/day (in addition to usual intake, depending on sex and weight) for 6 weeks, while the control group carried on with their usual intake. Participants collected a 24 h urine sample at baseline and at 2 and 6 weeks after randomisation. Our primary outcome was the between-group difference in change in 24 h urine volume from baseline to 6 weeks. Results (63%)of participants were men, 81% were Caucasians and the average age was 61 years (SD 14 years). The average baseline eGFR was 40 mL/min/1.73 m2 (SD 11 mL/min/1.73 m2); the median albumin to creatinine ratio was 19 mg/mmol (IQR 6–74 mg/mmol). Between baseline and 6-week follow-up, the hydration group's average 24 h urine volume increased by 0.7 L/day (from 2.3 to 3.0 L/day) and the control group's 24 h urine decreased by 0.3 L/day (from 2.0 to 1.7 L/day; between-group difference in change: 0.9 L/day (95% CI 0.4 to 1.5; p=0.002)). We found no significant changes in urine, serum osmolality or electrolyte concentrations, or eGFR. No serious adverse events or changes in quality of life were reported. Conclusions A pilot RCT indicates adults with stage 3 CKD can successfully and safely increase water intake by up to 0.7 L/day in addition to usual fluid intake.

    Since the discovery of the Hedgehog (Hh) pathway in drosophila melanogaster, our knowledge of the role of Hh in embryonic development, inflammation, and cancerogenesis in humans has dramatically increased over the last decades. This is the case especially concerning the pancreas, however, real therapeutic breakthroughs are missing until now. In general, Hh signaling is essential for pancreatic organogenesis, development, and tissue maturation. In the case of acute pancreatitis, Hh has a protective role, whereas in chronic pancreatitis, Hh interacts with pancreatic stellate cells, leading to destructive parenchym fibrosis and atrophy, as well as to irregular tissue remodeling with potency of initiating cancerogenesis. In vitro and in situ analysis of Hh in pancreatic cancer revealed that the Hh pathway participates in the development of pancreatic precursor lesions and ductal adenocarcinoma including critical interactions with the tumor microenvironment. The application of specific inhibitors of components of the Hh pathway is currently subject of ongoing clinical trials (phases 1 and 2). Furthermore, a combination of Hh pathway inhibitors and established chemotherapeutic drugs could also represent a promising therapeutic approach. In this review, we give a structured survey of the role of the Hh pathway in pancreatic development, pancreatitis, pancreatic carcinogenesis and pancreatic cancer as well as an overview of current clinical trials concerning Hh pathway inhibitors and pancreas cancer.

    Full Text Available Abstract Objective In general, chronic pancreatitis (CP primarily requires conservative treatment. The chronic pain syndrome and complications make patients seek surgical advice, frequently after years of progression. In the past, surgical procedures involving drainage as well as resection have been employed successfully. The present study compared the different surgical strategies. Patients and Methods From March 2000 until April 2005, a total of 51 patients underwent surgical treatment for CP at the Department of surgery, University of Schleswig-Holstein, Campus Lübeck. Out of those 51 patients, 39 (76.5% were operated according to the Frey procedure, and in 12 cases (23.5% the Whipple procedure was performed. Patient data were documented prospectively throughout the duration of the hospital stay. The evaluation of the postoperative pain score was carried out retrospectively with a validated questionnaire. Results Average operating time was 240 minutes for the Frey group and 411 minutes for the Whipple group. The medium number of blood transfusions was 1 in the Frey group and 4.5 in the Whipple group. Overall morbidity was 21% in the Frey group and 42% in the Whipple group. 30-day mortality was zero for all patients. During the median follow-up period of 50 months, an improvement in pain score was observed in 93% of the patients of the Frey group and 67% of the patients treated according to the Whipple procedure. Conclusion The results show that both the Frey procedure as well as partial pancreaticoduodenectomy are capable of improving chronic pain symptoms in CP. As far as later endocrine and exocrine pancreatic insufficiency is concerned, however, the extended drainage operation according to Frey proves to be advantageous compared to the traditional resection procedure by Whipple. Accordingly, the Frey procedure provides us with an organ-preserving surgical procedure which treats the complications of CP sufficiently, thus being an

    Chronic edema is a multifactorial condition affecting patients with various diseases. Although the pathophysiology of edema varies, compression therapy is a basic tenant of treatment, vital to reducing swelling. Clinical trials are disparate or lacking regarding specific protocols and application recommendations for compression materials and methodology to enable optimal efficacy. Compression therapy is a basic treatment modality for chronic leg edema; however, the evidence base for the optimal application, duration and intensity of compression therapy is lacking. The aim of this document was to present the proceedings of a day-long international expert consensus group meeting that examined the current state of the science for the use of compression therapy in chronic edema. An expert consensus group met in Brighton, UK, in March 2010 to examine the current state of the science for compression therapy in chronic edema of the lower extremities. Panel discussions and open space discussions examined the current literature, clinical practice patterns, common materials and emerging technologies for the management of chronic edema. This document outlines a proposed clinical research agenda focusing on compression therapy in chronic edema. Future trials comparing different compression devices, materials, pressures and parameters for application are needed to enhance the evidence base for optimal chronic oedema management. Important outcomes measures and methods of pressure and oedema quantification are outlined. Future trials are encouraged to optimize compression therapy in chronic edema of the lower extremities.

    Full Text Available Background and Aim. Mice with alymphoplasia (aly/aly mutation characterized by a lack of lymph nodes, Peyer's patches, and well-defined lymphoid follicles in the spleen were found. In this study, we used splenectomized aly/aly mice to elucidate the effects of secondary lymphoid organs in the development of aly/aly autoimmune pancreatitis. Methods. Forty-eight 10-week-old aly/aly mice were divided into two groups for splenectomy and sham operation. Histological and immunohistochemical analyses of the pancreas were performed at the ages of 20, 30, and 40 weeks old after operation, respectively. Results. Our results showed that mononuclear cell infiltration was restricted to the interlobular connective tissues at the age of 20 weeks, and not increase obviously at the age of 30 and 40 weeks in splenectomized aly/aly mice. Furthermore, an apparent decrease in the expressions of CD4+ T, CD8+ T, and B cells was detected in the pancreatic tissues compared with sham aly/aly mice, however, no significant difference in macrophage expression between mice with and without a splenectomy. Conclusions. Inflammation infiltration and development of the pancreatitis in aly/aly mice were suppressed effectively after splenectomy, which was, at least partly, correlated to inhibition of the infiltration of T and B cells in pancreatic tissues but not to macrophages.

  1. [Etiological factors of acute pancreatitis].

    Acute pancreatitis develops immediately after the causative impulse, while chronic pancreatitis develops after the long-term action of the noxious agent. A typical representative of acute pancreatitis is biliary pancreatitis, chronic pancreatitis develops in alcoholism and has a long latency. As alcoholic pancreatitis is manifested at first as a rule by a potent attack, it is classified in this stage as acute pancreatitis. The most frequent etiological factors in our civilization are thus cholelithiasis and alcoholism (both account for 20-50% in different studies). The assumed pathogenetic principles in acute biliary pancreatitis are the common canal of both efferent ducts above the obturated papilla, duodenopancreatic reflux and intrapancreatic hypertension. A detailed interpretation is however lacking. The pathogenesis of alcoholic pancreatitis is more complicated. Among others some part is played by changes in the calcium concentration and fusion of cellular membranes. Idiopathic pancreatitis occurs in up to 10%, part of the are due to undiagnosed alcoholism and cholelithiasis. Other etiologies are exceptional. Similarly as in cholelithiasis pancreatitis develops also during other pathological processes in the area of the papilla of Vater such as dysfunction of the sphincter of Oddi, ampulloma and juxtapapillary diverticulum, it is however usually mild. The incidence of postoperative pancreatitis is declining. Its lethality is 30% and the diagnosis is difficult. In the pathogenesis changes of the ion concentration are involved, hypoxia and mechanical disorders of the integrity of the gland. Pancreatitis develops in association with other infections--frequently in mumps, rarely in hepatitis, tuberculosis, typhoid and mycoses. Viral pancreatitis is usually mild. In parasitoses pancreatitis develops due to a block of the papilla Vateri. In hyperparathyroidism chronic pancreatitis is more likely to develop, recent data are lacking. As to dyslipoproteinaemias

    BACKGROUND: There is a growing evidence that matrix metalloproteinase (MMP)-2 and MMP-9 (gelatinases) play an important role in the pathogenesis of numerous disorders, especially with inflammatory etiology and extracellular matrix (ECM) remodeling. Despite the fact that gelatinases involve in liver cirrhosis is provided in the literature, their role in the pathogenesis of chronic pancreatitis and non-specific inflammatory bowel diseases is still under investigation. DATA SOURCES: We carried out a PubMed search of Englishlanguage articles relevant to the involvement of gelatinases in the pathogenesis of liver fibrosis, pancreatitis, and non-specific inflammatory bowel diseases. RESULTS: The decreased activity of gelatinases, especially MMP-2, is related to the development of liver fibrosis, probably due to the decrease of capability for ECM remodeling. Similar situation can be found in chronic pancreatitis; however, reports on this matter are rare. The presence of non-specific inflammatory bowel diseases results in MMP-9 activity elevation. CONCLUSION: The fluctuation of gelatinases activity during liver fibrosis, chronic pancreatitis and non-specific inflammatorybowel diseases is observed, but the exact role of these enzymes demands further studies.

    Full Text Available Pancreatic pseudocyst develops in both acute and chronic pancreatitis. It is an entity likely to either remain asymptomatic or develop devastating complications. Despite being diagnosed easily, treatment exercise is still at crossroads whether in the form of internal or external drainage or endoscopic, laparoscopic, or open intervention with a good radiological guidance. The therapeutic dilemma whether to treat a patient with a pancreatic pseudocyst, as well as when and with what technique, is a difficult one. This paper is intended to get information about diagnostic and therapeutic exercises most appropriate for acute and chronic pancreatic pseudocyst.

    Full Text Available Differential diagnosis of solid pancreatic lesions remains as an important clinical challenge, mainly for the differentiation between mass forming chronic pancreatitis, autoimmune pancreatitis and pancreatic adenocarcinoma. Endoscopic ultrasound (EUS, computed tomography (CT and magnetic resonance imaging (MRI can all provide valuable and complementary information in this setting. Among them, EUS has the unique ability to obtain specimens for histopathological diagnosis and can therefore play a crucial role in the evaluation patients with inconclusive findings on initial examinations. Nowadays, new developed techniques associated to EUS, like elastography and contrast enhancement, have shown promising results for the differential diagnosis of these pancreatic lesions.El diagnóstico diferencial de las lesiones sólidas pancreáticas permanece como un reto clínico importante, sobre todo para la diferenciación entre la masa de conformación pancreatitis crónica, pancreatitis autoinmune y el adenocarcinoma de páncreas.

    Full Text Available BACKGROUND The condition manifests as recurrent intractable abdominal pain. 1 This is the most important indication for surgical procedures. The pain is caused by increased pancreatic parenchymal and ductal pressure. Another cause is that chronic inflammation of the pancreas may lead to fibrosis of the peripancreatic capsule and perilobular parenchyma, which impairs local and regional blood flow, therefore causing pain through tissue ischaemia and acidosis. 2 This is the rationalisation behind adding the head coring to the decompression surgeries that had been classically in practice. METHODS This is a retrospective study. The study period spans over from January 2003 to December 2013, which is a 10-year period. Patients with intractable and non-relenting abdominal pain and a diagnosis of chronic pancreatitis with evidence of fibrosis of head of pancreas in imaging studies were included. 35 patients were randomly allocated for Head coring and LPJ by lottery method. The patients were analysed for duration of surgery, hospital stay, operative/postoperative complications and assessment of postoperative pain relief. Pain relief was assessed as complete (No analgesic required, satisfactory (Tolerable pain with normal daily activities and unsatisfactory (Hospitalisation and hampered daily activities. RESULTS Alcohol consumption (65.71% was the main cause of pancreatitis in the study group, followed by gallstones (14.28% and idiopathic (20% cause. Head coring (120 minutes takes a median operative time of 30 minutes more when done adjuvant to LPJ (90 minutes. Incidence of complications were comparable in both the surgeries. The common complications of prolonged ileus and wound infection are in the percentage of 12.5% in only LPJ and 15.78% in adjuvant head coring surgeries. Pain relief was good when the complete and satisfactory groups were compared. But there is not much of difference in unsatisfactory group comparison. CONCLUSION A 30 minutes

    2016-01-01

    Full Text Available Extra-abdominal complications of pancreatitis such as pancreaticopleural fistulae are rare. A pancreaticopleural fistula occurs when inflammation of the pancreas and pancreatic ductal disruption lead to leakage of secretions through a fistulous tract into the thorax. The underlying aetiology in the majority of cases is alcohol-induced chronic pancreatitis. The diagnosis is often delayed given that the majority of patients present with pulmonary symptoms and frequently have large, persistent pleural effusions. The diagnosis is confirmed through imaging and the detection of significantly elevated amylase levels in the pleural exudate. Treatment options include somatostatin analogues, thoracocentesis, endoscopic retrograde cholangiopancreatography (ERCP with pancreatic duct stenting, and surgery. The authors present a case of pancreatic pseudocyst pleural fistula in a woman with gallstone pancreatitis presenting with recurrent pneumonias and bilateral pleural effusions.

    Full Text Available Abstract Background Chronic whiplash is a common and costly problem. Sensory hypersensitivity is a feature of chronic whiplash that is associated with poor responsiveness to physical treatments such as exercise. Modalities such as dry-needling have shown some capacity to modulate sensory hypersensitivity, suggesting that when combined with advice and exercise, such an approach may be more effective in the management of chronic whiplash. The primary aim of this project is to investigate the effectiveness of dry-needling, advice and exercise for chronic whiplash. Method/Design A double-blind randomised controlled trial will be conducted. 120 participants with chronic whiplash, grade II will be randomised to receive either 1 dry-needling, advice and exercise or 2 sham dry-needling, advice and exercise. All participants will receive an educational booklet on whiplash. Participants who are randomised to Group 1 will receive 6 treatments of combined dry-needling and exercise delivered in the first 3 weeks of the 6 week program, and 4 treatments of exercise only in the last 3 weeks of the program. Participants randomised to Group 2 will receive an identical protocol, except that a sham dry-needling technique will be used instead of dry-needling. The primary outcome measures are the Neck Disability Index (NDI and participants' perceived recovery. Outcomes will be measured at 6, 12, 24 and 52 weeks after randomization by an assessor who is blind to the group allocation of the participants. In parallel, an economic analysis will be conducted. Discussion This trial will utilise high quality trial methodologies in accordance with CONSORT guidelines. The successful completion of this trial will provide evidence of the effectiveness and cost-effectiveness of a combined treatment approach for the management of chronic whiplash.

    A number of pharmacologic treatments examined in recent randomized clinical trials (RCTs) have failed to show statistically significant superiority to placebo in conditions in which their efficacy had previously been demonstrated. Assuming the validity of previous evidence of efficacy and the comparability of the patients and outcome measures in these studies, such results may be a consequence of limitations in the ability of these RCTs to demonstrate the benefits of efficacious analgesic treatments vs placebo ("assay sensitivity"). Efforts to improve the assay sensitivity of analgesic trials could reduce the rate of falsely negative trials of efficacious medications and improve the efficiency of analgesic drug development. Therefore, an Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials consensus meeting was convened in which the assay sensitivity of chronic pain trials was reviewed and discussed. On the basis of this meeting and subsequent discussions, the authors recommend consideration of a number of patient, study design, study site, and outcome measurement factors that have the potential to affect the assay sensitivity of RCTs of chronic pain treatments. Increased attention to and research on methodological aspects of clinical trials and their relationships with assay sensitivity have the potential to provide the foundation for an evidence-based approach to the design of analgesic clinical trials and expedite the identification of analgesic treatments with improved efficacy and safety.

    It is the major pathogenesis of chronic pancreatitis with portal hypertension (PHT) that the splenic veincompression or thrombosis, resulting in splenic vein occlusion. It usually shows symptoms of both chronic pancreatitis and PHT. The most common symptoms of chronic pancreatitis is that chronic upper abdominal and lumbar back pain. The performance of PHT is the different degrees of splenomegaly and hypersplenism, and isolated gastric varices, but the upper gastrointestinal bleeding is rare. It can be diagnosed by Doppler ultrasound, CT, MRI and angiography. Treatment should be aimed at both the primary disease and PHT. The individual treatment should be emphasized. The chronic pancreatitis with PHT can be cured with good prognosis.%慢性胰腺炎并发门静脉高压症(PHT)的主要发病机制为脾静脉受压或血栓形成,造成脾静脉闭塞;通常同时表现慢性胰腺炎和PHT症状,慢性上腹痛及腰背部疼痛是慢性胰腺炎最常见症状,PHT的表现是不同程度的脾肿大和脾功能亢进,孤立的胃底静脉曲张、上消化道出血不多见.通过多普勒超声、CT、MRI以及血管成像多可得出明确诊断.治疗应既针对原发病又要针对门静脉高压症,强调个体化治疗.由慢性胰腺炎引起的PHT是可以治愈的.

    Pancreatitis is an inflammatory condition of the pancreas which, in its chronic form, involves tissue destruction, exocrine and endocrine insufficiency, increased risk of pancreatic cancer, and an extensive fibrotic pathology which is due to unrelenting collagen deposition by pancreatic stellate cells (PSC). In response to noxious agents such as alcohol-excessive consumption of which is a major cause of pancreatitis in the West-normally quiescent PSC undergo a phenotypic and functional transition to activated myofibroblasts which produce and deposit collagen at high levels. This process is regulated by connective tissue growth factor (CCN2), expression of which is highly up-regulated in activated PSC. We show that CCN2 production by activated PSC is associated with enhanced expression of microRNA-21 (miR-21) which was detected at high levels in activated PSC in a murine model of alcoholic chronic pancreatitis. A positive feedback loop between CCN2 and miR-21 was identified that resulted in enhancement of their respective expression as well as that of collagen α1(I). Both miR-21 and CCN2 mRNA were present in PSC-derived exosomes, which were characterized as 50-150 nm CD9-positive nano-vesicles. Exosomes from CCN2-GFP- or miR-21-GFP-transfected PSC were taken up by other PSC cultures, as shown by direct fluorescence or qRT-PCR for GFP. Collectively these studies establish miR-21 and CCN2 as participants in a positive feedback loop during PSC activation and as components of the molecular payload in PSC-derived exosomes that can be delivered to other PSC. Thus interactions between cellular or exosomal miR-21 and CCN2 represent novel aspects of fibrogenic regulation in PSC. Summary Chronic injury in the pancreas is associated with fibrotic pathology which is driven in large part by CCN2-dependent collagen production in pancreatic stellate cells. This study shows that CCN2 up-regulation in PSC is associated with increased expression of miR-21 which, in turn, is able to

    The pathophysiology of pancreatic autodigestion is poorly understood. Pancreatitis affects all age groups, and the diagnosis is sometimes missed when serum amylase and lipase activities are not measured in the child with abdominal pain. Acute pancreatitis in children has become a more commonly seen condition and the causes have varied. Laboratory and radiological studies play an important role in determining the diagnosis and prognosis. Family history is important in the diagnosis of idiopathic hereditary pancreatitis. Most acute episodes resolve with supportive care, but the mortality in acute pancreatitis is currently about 15% (Hadorn et al., 1980). Endoscopic retrograde cholangiopancreatography or an endoscopic retrograde pancreatogram may be necessary to investigate relapses of pancreatitis. Chronic pancreatitis can be a life-threatening condition requiring lifetime medical management.

    Pain is a common symptom of pancreatic disease and is frequently difficult to manage. Pain relief provided by narcotics is often suboptimal and is associated with significant side effects. An alternative approach to pain management in pancreatic disease is the use of celiac plexus block (CPB) or neurolysis (CPN). Originally performed by anesthesiologists and radiologists via a posterior approach, recent advances in endoscopic ultrasonography (EUS) have made this technique an attractive altern...

    SUMMARY American tegumentary leishmaniasis is an infectious disease caused by a protozoan of the genus Leishmania. Pentavalent antimonials are the first choice drugs for cutaneous leishmaniasis (CL), although doses are controversial. In a clinical trial for CL we investigated the occurrence of pancreatic toxicity with different schedules of treatment with meglumine antimoniate (MA). Seventy-two patients were allocated in two different therapeutic groups: 20 or 5 mg of pentavalent antimony (Sb5+)/kg/day for 20 or 30 days, respectively. Looking for adverse effects, patients were asked about abdominal pain, nausea, vomiting or anorexia in each medical visit. We performed physical examinations and collected blood to evaluate serum amylase and lipase in the pre-treatment period, and every 10 days during treatment and one month post-treatment. Hyperlipasemia occurred in 54.8% and hyperamylasemia in 19.4% patients. Patients treated with MA 20 mg Sb5+ presented a higher risk of hyperlipasemia (p = 0.023). Besides, higher MA doses were associated with a 2.05 higher risk ratio (p = 0.003) of developing more serious (moderate to severe) hyperlipasemia. The attributable fraction was 51% in this group. Thirty-six patients presented abdominal pain, nausea, vomiting or anorexia but only 47.2% of those had hyperlipasemia and/ or hyperamylasemia. These findings suggest the importance of the search for less toxic therapeutic regimens for the treatment of CL. PMID:27680173

    We aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice in Germany run by a Chinese-born medical doctor trained in western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups (78 standardized and 72 individualized acupuncture). Patients received either standardized acupuncture or individualized acupuncture. Treatment encompassed between 10 and 15 treatments based on individual symptoms with two treatments per week. The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale (0 mm = no pain, 100 mm = worst imaginable pain). No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7 (95% CI, 1460.4; 2077.1); standardized acupuncture 1482.9 (1177.2; 1788.7); group difference, 285.8 (-33.9; 605.5) P = 0.080). In this single-center trial, individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain. As a next step, a multicenter noninferiority study should be performed to investigate whether standardised acupuncture treatment for chronic low back pain might be applicable in a broader usual care setting.

    Full Text Available Abstract Background Pain is often a dominant clinical feature of chronic pancreatitis but the frequency and severity is highly variable between subjects. We hypothesized that genetic polymorphisms contribute to variations in clinical pain patterns. Since genetic variations in the GTP cyclohydrolase (GCH1 gene have been reported to protect some patients from pain, we investigated the effect of the "pain protective haplotype" in well characterized patients with chronic pancreatitis (CP or recurrent acute pancreatitis (RAP from the North American Pancreatitis Study 2 (NAPS2. Results Subjects in the NAPS2 study were asked to rank their pain in one of 5 categories reflecting different levels of pain frequency and severity. All subjects were genotyped at rs8007267 and rs3783641 to determine the frequency of the GCH1 pain-protective haplotype. In Caucasian subjects the frequency of the pain-protective GCH1 haplotype was no different in the control group (n = 236, CP patients (n = 265, RAP patients (N = 131, or in CP patients subclassified by pain category compared to previously reported haplotype frequencies in the general Caucasian population. Conclusion The GCH1 pain-protective haplotype does not have a significant effect on pain patterns or severity in RAP or CP. These results are important for helping to define the regulators of visceral pain, and to distinguish different mechanisms of pain.

    Since the discovery of the Hedgehog(Hh)pathway in drosophila melanogaster,our knowledge of the role of Hh in embryonic development,inflammation,and cancerogenesis in humans has dramatically increased over the last decades.This is the case especially concerning the pancreas,however,real therapeutic breakthroughs are missing until now.In general,Hh signaling is essential for pancreatic organogenesis,development,and tissue maturation.In the case of acute pancreatitis,Hh has a protective role,whereas in chronic pancreatitis,Hh interacts with pancreatic stellate cells,leading to destructive parenchym fibrosis and atrophy,as well as to irregular tissue remodeling with potency of initiating cancerogenesis.In vitro and in situ analysis of Hh in pancreatic cancer revealed that the Hh pathway participates in the development of pancreatic precursor lesions and ductal adenocarcinoma including critical interactions with the tumor microenvironment.The application of specific inhibitors of components of the Hh pathway is currently subject of ongoing clinical trials(phases 1 and 2).Furthermore,a combination of Hh pathway inhibitors and established chemotherapeutic drugs could also represent a promising therapeutic approach.In this review,we give a structured survey of the role of the Hh pathway in pancreatic development,pancreatitis,pancreatic carcinogenesis and pancreatic cancer as well as an overview of current clinical trials concerning Hh pathway inhibitors and pancreas cancer.

    Effective therapeutic options for patients living with chronic pain are limited. The pain relieving effect of cannabinoids remains unclear. A systematic review of randomized controlled trials (RCTs) examining cannabinoids in the treatment of chronic non-cancer pain was conducted according to the PRISMA statement update on the QUORUM guidelines for reporting systematic reviews that evaluate health care interventions. Cannabinoids studied included smoked cannabis, oromucosal extracts of cannabis based medicine, nabilone, dronabinol and a novel THC analogue. Chronic non-cancer pain conditions included neuropathic pain, fibromyalgia, rheumatoid arthritis, and mixed chronic pain. Overall the quality of trials was excellent. Fifteen of the eighteen trials that met the inclusion criteria demonstrated a significant analgesic effect of cannabinoid as compared with placebo and several reported significant improvements in sleep. There were no serious adverse effects. Adverse effects most commonly reported were generally well tolerated, mild to moderate in severity and led to withdrawal from the studies in only a few cases. Overall there is evidence that cannabinoids are safe and modestly effective in neuropathic pain with preliminary evidence of efficacy in fibromyalgia and rheumatoid arthritis. The context of the need for additional treatments for chronic pain is reviewed. Further large studies of longer duration examining specific cannabinoids in homogeneous populations are required.

The Chronic Care Model represents an evidence-based framework for the care for chronically ill. An increasing number of studies showed that implementing elements of the Chronic Care Model improves patient relevant outcomes and process parameters. However, most of these findings have been performed in settings different from the Swiss health care system which is dominated by single handed practices. Methods/Design CARAT is a cluster randomized controlled trial with general practitioners as the unit of randomization (trial registration: ISRCTN05947538. The study challenges the hypothesis that implementing several elements of the Chronic Care Model via a specially trained practice nurse improves the HbA1c level of diabetes type II patients significantly after one year (primary outcome. Furthermore, we assume that the intervention increases the proportion of patients who achieve the recommended targets regarding blood pressure ( Discussion This study challenges the hypothesis that the Chronic Care Model can be easily implemented by a practice nurse focused approach. If our results will confirm this hypothesis the suggestion arises whether this approach should be implemented in other chronic diseases and multimorbid patients and how to redesign care in Switzerland.

    BACKGROUND:The presence of pancreatic ductal intraepithelial neoplasia in patients with chronic pancreatitis is a risk factor for development of pancreatic adenocarcinoma. METHOD: A case of pancreatic ductal adenocarcinoma associated with pancreatic ductal intraepithelial neoplasia was diagnosed in the setting of chronic pancreatitis. RESULTS:Distal pancreatectomy combined with splenec-tomy was performed with a diagnosis of pancreatic body carcinoma. Histopathological examination suggested adenocarcinoma associated with pancreatic ductal intraepithelial neoplasia. The tumor was detected in the remaining head of the pancreas, for which a total pancreatectomy was done. CONCLUSIONS: When a patient with pancreatic ductal intraepithelial neoplasia associated with adenocarcinoma of the pancreas in the setting of chronic pancreatitis is at an increased risk of recurrence in the remaining pancreatic parenchyma, total pancreatectomy may be feasible.

    2008-09-01

    Diabetes mellitus is a common disease among patients with pancreatic cancer and chronic pancreatitis, disorders of the exocrine pancreas. Different clinical features of diabetes are associated with these two conditions: hyperinsulinemia and peripheral insulin resistance are the prevailing diabetic traits in pancreatic cancer, whereas reduced islet cell mass and impaired insulin secretion are typically observed in chronic pancreatitis. Whether or not a causal relationship exists between diabetes and pancreatic carcinoma is an intriguing but unanswered question. Diabetes often precedes pancreatic cancer and is thus regarded as a potential risk factor for malignancy. Conversely, pancreatic cancer may secrete diabetogenic factors. Given these findings, there is increasing interest in whether close monitoring of the glycemic profile may aid early detection of pancreatic tumor lesions.

    Acute pancreatitis is a frequent inflammatory and necrotic process of pancreas and peripancreatic field. To detect the presence of infected or sterile necrotic components and hemorrhage of the pancreatic paranchyma is important for therapeutic approach. Chronic pancreatitis is characterized by irreversible exocrine dysfunction, progressive loss of pancreatic tissue and morphological changes of the pancreatic canal. Imaging modalities play a primary role in the management of both acute and chronic pancreatitis. CT and MR imaging confirm the diagnosis and detect the severity of disease. In chronic pancreatitis, MRCP after Secretin administration, Spiral CT and endoscopic US seems to replace diagnostic ERCP. However differentiation of pseudotumor of chronic pancreatitis from the pancreatic carcinoma is difficult with either imaging modalities.

    Full Text Available Kara L Raphael, Field F Willingham Division of Digestive Diseases, Department of Medicine, Emory University School of Medicine, Atlanta, GA, USA Abstract: Hereditary pancreatitis (HP is a rare cause of acute, recurrent acute, and chronic pancreatitis. It may present similarly to other causes of acute and chronic pancreatitis, and often there has been a protracted evaluation prior to the diagnosis of HP. Since it was first described in 1952, multiple genetic defects that affect the action of digestive enzymes in the pancreas have been implicated. The most common mutations involve the PRSS1, CFTR, SPINK1, and CTRC genes. New mutations in these genes and previously unrecognized mutations in other genes are being discovered due to the increasing use of next-generation genomic sequencing. While the inheritance pathways of these genetic mutations may be variable and complex, sometimes involving coinheritance of other mutations, the clinical presentation of patients tends to be similar. Interactions with environmental triggers often play a role. Patients tend to present at an early age (prior to the second decade of life and have a significantly increased risk for the development of pancreatic adenocarcinoma. Patients with HP may develop sequelae of chronic pancreatitis such as strictures and fluid collections as well as exocrine and endocrine insufficiency. Management of patients with HP involves avoidance of environmental triggers, surveillance for pancreatic adenocarcinoma, medical therapy for endocrine and exocrine insufficiency, pain management, and endoscopic or surgical treatment for complications. Care for affected patients should be individualized, with an emphasis on early diagnosis and multidisciplinary involvement to develop a comprehensive treatment strategy.

    Pancreatic cancer is molecularly diverse, with few effective therapies. Increased mutation burden and defective DNA repair are associated with response to immune checkpoint inhibitors in several other cancer types. We interrogated 385 pancreatic cancer genomes to define hypermutation and its causes. Mutational signatures inferring defects in DNA repair were enriched in those with the highest mutation burdens. Mismatch repair deficiency was identified in 1% of tumors harboring different mechanisms of somatic inactivation of MLH1 and MSH2. Defining mutation load in individual pancreatic cancers and the optimal assay for patient selection may inform clinical trial design for immunotherapy in pancreatic cancer.

    Full Text Available Abstract Background Use of acupuncture has widely increased in patients with chronic low back pain. However, the evidence supporting its efficacy remains unclear. In this article, we report the design and the protocol of a multi-center randomized sham-controlled trial to treat chronic low back pain. Our goal is to verify the effect of acupuncture on chronic low back pain. Methods/Design This study is a multi-center randomized sham-controlled trial with 2 parallel arms. Participants included in the study met the following criteria: 1 low back pain lasting for at least the last 3 months, 2 a documented ≥ 5 points on a 10 cm visual analog scale for bothersomeness of low back pain at the time of screening and 3 between 18 and 65 years of age. Participants were blinded to the real and sham acupuncture treatments. The real acupuncture treatment group received real acupuncture 2 times a week, during a total of 12 sessions over 6 weeks. The control group received sham acupuncture during the same period. In order to assess the primary and secondary outcome measures, the participants were asked to fill out a questionnaire at the baseline and 6, 8, 12 and 24 weeks after starting the treatments. The primary outcome was measured using the visual analog scale for bothersomeness of low back pain at 8 weeks after the initiation of treatments. Discussion The result of this trial (which will be available in 2010 will demonstrate the efficacy of using acupuncture to treat chronic low back pain.

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months.

    Full Text Available To determine whether treatment with omega-3 fatty acids (ω-3 FA provides benefits to patients with acute pancreatitis (AP. The Cochrane Library, PubMed, Embase, Web of Science, and Chinese Biomedical Literature Database were searched. Data analysis was performed using Revman 5.2 software. A total of eight randomized controlled trials (RCTs were included. Overall, ω-3 FA treatment resulted in a significantly reduced risk of mortality (RR 0.35; 95% CI 0.16 to 0.75, p < 0.05, infectious complications (RR 0.54; 95% CI 0.34 to 0.85, p < 0.05 and length of hospital stay (MD –6.50; 95% CI −9.54 to −3.46, p < 0.05, but not length of ICU stay (MD −1.98; 95% CI −6.92 to 2.96, p > 0.05. In subgroup analysis, only patients who received ω-3 FA parenterally had some statistically significant benefits in terms of mortality (risk ratio (RR 0.37; 95% confidence interval (CI 0.16 to 0.86, p < 0.05, infectious complications (RR 0.5; 95% CI 0.28 to 0.9, p < 0.05 and length of hospital stay (mean difference (MD −8.13; 95% CI −10.39 to −5.87, p < 0.001. The administration of ω-3 FA may be beneficial for decreasing mortality, infectious complications, and length of hospital stay in AP, especially when used parenterally. Large and rigorously designed RCTs are required to elucidate the efficacy of parenteral or enteral ω-3 FA treatment in AP.

    The usefulness of enteral nutrition via a nasointestinal tube for patients who develop postoperative pancreatic fistula (POPF) after miscellaneous pancreatectomy procedures has been reported. However, no clear evidence regarding whether oral intake is beneficial or harmful during management of POPF after distal pancreatectomy (DP) is currently available.To investigate the effects of oral food intake on the healing process of POPF after DP.Multi-institutional randomized controlled trial in Nagoya University Hospital and 4 affiliated hospitals.Patients who developed POPF were randomly assigned to the dietary intake (DI) group (n = 15) or the fasted group (no dietary intake [NDI] group) (n = 15). The primary endpoint was the length of drain placement.No significant differences were found in the length of drain placement between the DI and NDI groups (12 [6-58] and 12 [7-112] days, respectively; P = 0.786). POPF progressed to a clinically relevant status (grade B/C) in 5 patients in the DI group and 4 patients in the NDI group (P = 0.690). POPF-related intra-abdominal hemorrhage was found in 1 patient in the NDI group but in no patients in the DI group (P = 0.309). There were no significant differences in POPF-related intra-abdominal hemorrhage, the incidence of other complications, or the length of the postoperative hospital stay between the 2 groups.Food intake did not aggravate POPF and did not prolong drain placement or hospital stay after DP. There may be no need to avoid oral DI in patients with POPF.

    Purpose: The aim of this trial was to evaluate the efficacy and toxicity of S-1 and concurrent radiation therapy for locally advanced pancreatic cancer (PC). Methods and Materials: Locally advanced PC patients with histologically or cytologically confirmed adenocarcinoma or adenosquamous carcinoma, who had no previous therapy were enrolled. Radiation therapy was delivered through 3 or more fields at a total dose of 50.4 Gy in 28 fractions over 5.5 weeks. S-1 was administered orally at a dose of 80 mg/m{sup 2} twice daily on the day of irradiation during radiation therapy. After a 2- to 8-week break, patients received a maintenance dose of S-1 (80 mg/m{sup 2}/day for 28 consecutive days, followed by a 14-day rest period) was then administered until the appearance of disease progression or unacceptable toxicity. The primary efficacy endpoint was survival, and the secondary efficacy endpoints were progression-free survival, response rate, and serum carbohydrate antigen 19-9 (CA19-9) response; the safety endpoint was toxicity. Results: Of the 60 evaluable patients, 16 patients achieved a partial response (27%; 95% confidence interval [CI], 16%-40%). The median progression-free survival period, overall survival period, and 1-year survival rate of the evaluable patients were 9.7 months (95% CI, 6.9-11.6 months), 16.2 months (95% CI, 13.5-21.3 months), and 72% (95%CI, 59%-82%), respectively. Of the 42 patients with a pretreatment serum CA19-9 level of {>=}100 U/ml, 34 (81%) patients showed a decrease of greater than 50%. Leukopenia (6 patients, 10%) and anorexia (4 patients, 7%) were the major grade 3-4 toxicities with chemoradiation therapy. Conclusions: The effect of S-1 with concurrent radiation therapy in patients with locally advanced PC was found to be very favorable, with only mild toxicity.

  9. Pancreatic pseudocyst

    Pancreatic pseudocysts are complications of acute or chronic pancreatitis. Initial diagnosis is accomplished most often by cross-sectional imaging. Endoscopic ultrasound with fine needle aspiration has become the preferred test to help distinguish pseudocyst from other cystic lesions of the pancreas. Most pseudocysts resolve spontaneously with supportive care. The size of the pseudocyst and the length of time the cyst has been present are poor predictors for the potential of pseudocyst resolution or complications, but in general, larger cysts are more likely to be symptomatic or cause complications. The main two indications for some type of invasive drainage procedure are persistent patient symptoms or the presence of complications (infection, gastric outlet or biliary obstruction, bleeding). Three different strategies for pancreatic pseudocysts drainage are available: endoscopic (transpapillary or transmural) drainage, percutaneous catheter drainage, or open surgery. To date, no prospective controlled studies have compared directly these approaches. As a result, the management varies based on local expertise, but in general, endoscopic drainage is becoming the preferred approach because it is less invasive than surgery, avoids the need for external drain, and has a high long-term success rate. A tailored therapeutic approach taking into consideration patient preferences and involving multidisciplinary team of therapeutic endoscopist, interventional radiologist and pancreatic surgeon should be considered in all cases.

    Full Text Available BACKGROUND: Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP. Several clinical trials used glyceryl trinitrate (GTN to prevent the incidence of post-ERCP pancreatitis (PEP. However, the results were still controversial. OBJECTIVE: To conduct a meta-analysis of published, full-length, randomized controlled trials evaluating the effect of prophylactic GTN on the prevention of PEP, improve the rate of cannulation and the prevention of hyperamylasemia. METHODS: Literature searches were conducted using PubMed, EMBASE, The Cochrane Library and Web of Knowledge databases, using keywords "post-ERCP" and "pancreatitis" and limited in randomized controlled trials. RESULTS: Twelve RCTs involving 2649 patients were included. Eleven RCTs compared GTN with placebo for PEP prevention. Meta-analysis showed the overall incidence of PEP was significantly reduced by GTN treatment (RR 0.67; 95% CI, 0.52-0.87. Nevertheless, GTN administration did not decrease the incidence of moderate to severe PEP (RR 0.70; 95% CI, 0.42-1.15. Subgroup analyses revealed that GTN administered by sublingual was more effective than transdermal and topical in reducing the incidence of PEP. Besides, the prophylactic effect of GTN was far more obvious in the group of high PEP incidence than in the group of low PEP incidence. Additionally, the incidence of hyperamylasemia was significantly reduced by GTN treatment (RR 0.69; 95% CI, 0.54-0.90. No differences of the successful cannulation rate of bile ducts (RR 1.03; 95% CI, 0.99-1.06 attributable to GTN were observed. CONCLUSION: Prophylactic use of GTN reduced the overall incidence of PEP and hyperamylasemia. However, GTN was not helpful for the severity of PEP and the rate of cannulation.

    Full Text Available Abstract Background Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS. As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS. Methods A total of 56 patients with chronic PFPS were randomized into two treatment groups: an arthroscopy group (N = 28, treated with knee arthroscopy and an 8-week home exercise program, and a control group (N = 28, treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and function at 9 months following randomization. Secondary outcomes were visual analog scales (VASs to assess activity-related symptoms. We also estimated the direct healthcare costs. Results Both groups showed marked improvement during the follow-up. The mean improvement in the Kujala score was 12.9 (95% confidence interval (CI 8.2–17.6 in the arthroscopy group and 11.4 (95% CI 6.9–15.8 in the control group. However, there was no difference between the groups in mean improvement in the Kujala score (group difference 1.1 (95% CI -7.4 - 5.2 or in any of the VAS scores. Total direct healthcare costs in the arthroscopy group were estimated to exceed on average those of the control group by €901 per patient (p Conclusion In this controlled trial involving patients with chronic PFPS, the outcome when arthroscopy was used in addition to a home exercise program was no better than when the home exercise program was used alone.

    Editors' Summary Background. Diabetes is an increasingly common chronic disease characterized by high blood sugar (glucose) levels. In normal people, blood sugar levels are controlled by the hormone insulin. Insulin is released by β-cells in the pancreas when blood glucose levels rise after eating (glucose is produced by the digestion of food). In fasting people, membrane proteins called ATP-sensitive potassium (KATP) channels keep the β-cell in a “hyperpolarized” state in which they do not s...

    The purpose of this randomized noninferiority trial was to compare video teleconferencing (VTC) versus in-person (IP) delivery of an 8-week acceptance and commitment therapy (ACT) intervention among veterans with chronic pain (N = 128) at post-treatment and at 6-month follow-up. The primary outcome was the pain interference subscale of the Brief Pain Inventory. Secondary outcomes included measures of pain severity, mental and physical health-related quality of life, pain acceptance, activity level, depression, pain-related anxiety, and sleep quality. In intent to treat analyses using mixed linear effects modeling, both groups exhibited significant improvements on primary and secondary outcomes, with the exception of sleep quality. Further, improvements in activity level at 6-month follow-up were significantly greater in the IP group. The noninferiority hypothesis was supported for the primary outcome and several secondary outcomes. Treatment satisfaction was similar between groups; however, significantly more participants withdrew during treatment in the VTC group compared with the IP group, which was moderated by activity level at baseline. These findings generally suggest that ACT delivered via VTC can be as effective and acceptable as IP delivery for chronic pain. Future studies should examine the optimal delivery of ACT for patients with chronic pain who report low levels of activity. This trial was registered at ClinicalTrials.gov (NCT01055639).

    Some patients have persistence of profound fatigue, myalgias, arthralgias without arthritis, dysesthesia/paresthesia, and mood and memory disturbances after standard courses of antibiotic treatment for Lyme disease. This constellation of symptoms has been variously referred to as "chronic Lyme disease," "post-Lyme disease syndrome," and "post-treatment chronic Lyme disease." Persistent symptoms have been reported in patients who are seropositive for IgG antibodies against Borrelia burgdorferi as well as in patients who are seronegative. The cause or causes of persistent symptoms in these patients have not been clearly defined and are controversial. Because of the temporal association of these symptoms with infection with B. burgdorferi, some patients have been treated with prolonged courses of antibiotics. Case reports and uncontrolled trials have reported the efficacy of prolonged antibiotic therapy, often with relapse of the symptoms after discontinuation of therapy. To date, only one randomized, placebo-controlled, double-blind trial of antibiotic therapy for these patients has been published. An abstract of a second placebo-controlled trial of antibiotic therapy in a smaller cohort has also been presented. This paper will describe this patient population in detail and will review the clinical, microbiological, and selected biochemical and immunologic parameters and their responses to antibiotic treatment in the setting of a controlled trial.

    Idiopathic chronic fatigue is an exclusion diagnosis established when no chronic disease is found. Spirulina platensis is an alga with a rich content of proteins, vitamins, minerals and amino acids and is considered as a bioactive additive with multiple effects, among them being effects against fatigue. However, despite the worldwide utilization of Spirulina, there are only a few quality studies with it and none concerning fatigue. The N-of-1 randomized trials are made on one patient, and by this kind of study the efficacy of a treatment on that particular patient can be assessed. A series of four N-of-1 double-blind, randomized trials were performed on four physicians who complained of chronic fatigue. Each patient was his own control and received three pairs of treatments comprising 4 weeks of spirulina and 4 weeks of placebo. Spirulina platensis was administered in a dose of 3 g/day. For each pair, the order of treatments was randomized. Outcome measures were severity of fatigue measured on a 10-point scale. The scores of fatigue were not significantly different between spirulina and placebo. Spirulina administered in a dose of 3 g/day did not ameliorate fatigue more than the placebo in any of the four subjects, and possibly it has no effect on chronic fatigue.

  20. Physiotherapy for sleep disturbance in chronic low back pain: a feasibility randomised controlled trial.

    Hurley, Deirdre A

    2010-01-01

    Sleep disturbance is becoming increasingly recognised as a clinically important symptom in people with chronic low back pain (CLBP, low back pain >12 weeks), associated with physical inactivity and depression. Current research and international clinical guidelines recommend people with CLBP assume a physically active role in their recovery to prevent chronicity, but the high prevalence of sleep disturbance in this population may be unknowingly limiting their ability to participate in exercise-based rehabilitation programmes and contributing to poor outcomes. There is currently no knowledge concerning the effectiveness of physiotherapy on sleep disturbance in people with chronic low back pain and no evidence of the feasibility of conducting randomized controlled trials that comprehensively evaluate sleep as an outcome measure in this population.

Laparoscopic cholecystectomy is the gold standard treatment for prevention of further attacks of acute biliary pancreatitis. Bile duct calculi detected at intraoperative cholangiography in patients with mild attacks of pancreatitis may be safely managed with laparoscopic bile duct exploration. Laparoscopic internal drainage of large, persistent and symptomatic pancreatic pseudocysts is safely applicable to most patients, achieves adequate drainage and facilitates debridement, and brings recognised benefits over open surgery and endoscopic approaches. Laparoscopic pancreatic necrosectomy for infected necrosis is feasible in some patients but the benefits of this approach in this high-risk group of patients remain to be shown. Staging laparoscopy and laparoscopic ultrasound avoids unnecessary laparotomy in approximately one-fifth of patients with pancreatic cancer, but their routine application in patients with ampullary and duodenal cancers is not warranted. The majority of patients with periampullary cancer have locally advanced or metastatic disease at presentation and their management is entirely palliative. Laparoscopic surgery therefore has its place in the relief of biliary and gastric outlet obstruction, and has its advantages over endoscopic biliary and duodenal stenting in patients with predicted better prognosis, though these advantages ought to be confirmed in randomised controlled trials. Thoracoscopic splanchnicectomy is beneficial in the short-to-medium term for the palliation of intractable opiate-dependent abdominal pain of locally advanced pancreatic cancer and that of chronic pancreatitis with demonstrable improvements in quality of life.

    Pancreatic cancer is a relatively uncommon tumor, but even with early diagnosis, mortality rates are high, explaining why this form of cancer has now become a common cause of cancer mortality. There are no screening tests for early detection of pancreatic cancer. It is more common in men than women and is predominantly a disease of elderly people. There is wide variation in the incidence of pancreatic cancer around the world, suggesting that environmental factors are important in the pathogenesis. Smoking is the major known risk factor for pancreatic cancer, while dietary factors seem to be less important. Other possible risk factors include chronic pancreatitis, obesity and type 2 diabetes. Numerous inherited germ line mutations are associated with pancreatic cancer. Of these, hereditary pancreatitis confers the greatest risk, while BRCA2 mutations are the commonest inherited disorder. Polymorphisms in genes that control detoxification of environmental carcinogens and metabolic pathways may alter the risk of pancreatic cancer.

    Endoscopic ultrasonography is an established diagnostic tool for pancreatic masses and chronic pancreatitis. In recent years there has been a growing interest in the worldwide medical community in autoimmune pancreatitis (AIP), a form of chronic pancreatitis caused by an autoimmune process. This paper reviews the current available literature about the endoscopic ultrasonographic findings of AIP and the role of this imaging technique in the management of this protean disease.

    Full Text Available Autoimmune pancreatitis is a rare type of chronic pancreatitis. It is supposed to be a pancreatic manifestation of an immune-complex modulated systemic disorder. In contrast, pancreatic adenocarcinoma is the most frequent malignant neoplasm of the pancreas. Within the rare type of focal autoimmune pancreatitis, only few presentations with multifocal pancreatic lesions have been described. Herein we report a case of a 58-year-old patient with autoimmune pancreatitis presenting with bifocal manifestations of the pancreatic head and tail, mimicking pancreatic adenocarcinoma clinically, on computed tomography and magnetic resonance imaging. Typical imaging findings of autoimmune pancreatitis are compared with typical findings in pancreatic carcinoma. The diagnostic dilemma of differentiating between both entities is discussed. A review of the present literature regarding multifocal presence of autoimmune pancreatitis is performed.

    Full Text Available Abstract Background Chronic non-specific low-back pain (LBP is one of the most common and expensive musculoskeletal disorders in industrialized countries. Similar to other countries in the world, LBP is a common health and socioeconomic problem in Iran. One of the most widely used modalities in the field of physiotherapy for treating LBP is therapeutic ultrasound. Despite its common use, there is still inconclusive evidence to support its effectiveness in this group of patients. This randomised trial will evaluate the effectiveness of continuous ultrasound in addition to exercise therapy in patients with chronic LBP. Methods and design A total of 46 patients, between the ages 18 and 65 years old who have had LBP for more than three months will be recruited from university hospitals. Participants will be randomized to receive continuous ultrasound plus exercise therapy or placebo ultrasound plus exercise therapy. These groups will be treated for 10 sessions during a period of 4 weeks. Primary outcome measures will be functional disability and pain intensity. Lumbar flexion and extension range of motion, as well as changes in electromyography muscle fatigue indices, will be measured as secondary outcomes. All outcome measures will be measured at baseline, after completion of the treatment sessions, and after one month. Discussion The results of this trial will help to provide some evidence regarding the use of continuous ultrasound in chronic LBP patients. This should lead to a more evidence-based approach to clinical decision making regarding the use of ultrasound for LBP. Trial registration Netherlands Trial Register (NTR: NTR2251

    Src tyrosine kinases are overexpressed in pancreatic cancers, and the oral Src inhibitor saracatinib has shown antitumor activity in preclinical models of pancreas cancer. We performed a CTEP-sponsored Phase II clinical trial of saracatinib in previously treated pancreas cancer patients, with a primary endpoint of 6-month survival. A Simon MinMax two-stage phase II design was used. Saracatinib (175 mg/day) was administered orally continuously in 28-day cycles. In the unselected portion of the study, 18 patients were evaluable. Only two (11%) patients survived for at least 6 months, and three 6-month survivors were required to move to second stage of study as originally designed. The study was amended as a biomarker-driven trial (leucine rich repeat containing protein 19 [LRRC19] > insulin-like growth factor-binding protein 2 [IGFBP2] "top scoring pairs" polymerase chain reaction [PCR] assay, and PIK3CA mutant) based on preclinical data in a human pancreas tumor explant model. In the biomarker study, archival tumor tissue or fresh tumor biopsies were tested. Biomarker-positive patients were eligible for the study. Only one patient was PIK3CA mutant in a 3' untranslated region (UTR) portion of the gene. This patient was enrolled in the study and failed to meet the 6-month survival endpoint. As the frequency of biomarker-positive patients was very low (pancreatic cancer patients treated with a Src inhibitor based on a biomarker would improve 6-month survival, we demonstrate that testing pancreatic tumor samples for a biomarker-driven, multicenter study in metastatic pancreas cancer is feasible.

    The incidence of chronic pancreatitis (CP) is increasing, and dyslipidemia severely affects the health of middle-aged and elderly people. We investigated the association between blood lipid levels and CP. The serum lipid metabolic indices of 48 patients with CP (CP group) were summarized retrospectively. The physical examination results of 40 randomly selected healthy individuals were used as the normal control (NC) group. Statistical analyses of the blood lipid data were performed between the 2 groups using the case-control study method. High-density lipoprotein-cholesterol (HDL-c) levels decreased and fasting blood glucose (GLU) levels increased in the CP group compared with those in the NC group (P<0.01). Pearson correlation analysis results showed that serum amylase (AMY) was positively correlated with low-density lipoprotein-cholesterol (LDL-c; r=0.414, P<0.05), and urine AMY (UAMY) was positively correlated with total cholesterol (TC; r=0.614, P<0.01) and LDL-c (r=0.678, P<0.01). A binary logistic regression analysis showed that GLU (odds ratio [OR], 5.052; P<0.01) and TC (OR, 1.074; P<0.01) may be risk factors for CP, whereas HDL-c may be a CP protective factor (OR, 0.833; P<0.01). The HDL-c levels decreased and GLU levels increased in the CP group compared with those in the NC group; AMY was positively correlated with LDL-c and UAMY was positively correlated with TC and LDL-c; GLU and TC may be risk factors for CP; and HDL-c may be a CP protective factor. This may be the first time that such results have been reported. These findings will contribute to primary prevention and control of CP progression.

    Full Text Available Abstract Background Hand eczema has a one-year prevalence of approximately 10 % in the general Danish population. Often the disease becomes chronic with numerous implications for the individual’s daily life, occupation and quality of life. However, no guidelines of self-management recommendations beyond the acute stage are given. Self-management of the disease is pivotal and involves self-monitoring of the condition, medication adherence, and preventive behaviour. Interventions best to support the individual in this ongoing process need to be developed. Methods/design This paper describes the design of a randomised clinical trial to test a newly developed intervention of individual counselling versus conventional information. 300 patients consecutively referred to dermatologic treatment at two different settings are individually randomised to either the intervention programme, named ‘The Healthy Skin Clinic’ or to the control group. Block-wise randomisation according to setting and gender is carried out. The intervention offers a tool for self-monitoring; basic and specific individual counselling; the possibility of asynchronous communication with the intervention team; and an electronic patient dialogue forum. Primary outcome variable is objective assessment of the hand eczema severity performed at baseline prior to randomisation, and repeated at six months follow-up. Secondary outcome variables are dermatology related life quality and perceived global burden of disease. Discussion The trial aims at evaluating a newly developed guidance programme which is expected to support self-management of patients referred to dermatology treatment due to chronic hand eczema. The design of the protocol is pragmatic with blinding of neither participants nor the investigator. Thus, in the interpretation of the results, the investigator takes into account effects that may be attributed to actors of the interventions rather than the intervention per se as

    Full Text Available This paper reports on the findings of a user trial of a mHealth application for pressure ulcer (bedsore documentation. Pressure ulcers are a leading iatrogenic cause of death in developed countries and significantly impact quality of life for those affected. Pressure ulcers will be an increasing public health concern as the population ages. Electronic information systems are being explored to improve consistency and accuracy of documentation, improve patient and caregiver experience and ultimately improve patient outcomes. A software application was developed for Android Smartphones and tablets and was trialed in a personal care home in Western Canada. The software application provides an electronic medical record for chronic wounds, replacing nurses’ paper-based charting and is positioned for integration with facility’s larger eHealth framework. The mHealth application offers three intended benefits over paper-based charting of chronic wounds, including: (1 the capacity for remote consultation (telehealth between facilities, practitioners, and/or remote communities, (2 data organization and analysis, including built-in alerts, automatically-generated text-based and graph-based wound histories including wound images, and (3 tutorial support for non-specialized caregivers. The user trial yielded insights regarding the software application’s design and functionality in the clinical setting, and highlighted the key role of wound photographs in enhancing patient and caregiver experiences, enhancing communication between multiple healthcare professionals, and leveraging the software’s telehealth capacities.

    Full Text Available INTRODUCTION: The exact mechanism of chronic nonbacterial prostatitis has not been yet elucidated and the outcome with the current management is dismal. In this trial, we studied the effect of allopurinol in the treatment of this disease. MATERIALS AND METHODS: In this randomized double blind controlled trial, a calculated sample size of 56 were grouped into "intervention group" who received allopurinol (100 mg tds for 3 months with ofloxacin (200 mg tds for 3 weeks (n = 29 and "control group" who received placebo tablets with ofloxacin (n = 27. Patients’ scores based on the National Institute of Health Chronic Prostatitis Symptom Score were recorded before therapy and then every month during the study. A four-glass study was performed before intervention and after 3 months. RESULTS: The 2 groups were similar regarding outcome variables. In the first month of study, a significant but similar improvement in symptom scores was observed in both groups. Microscopic examination of prostate massage and post-massage samples were also similar in both groups. No side effects due to allopurinol were observed in patients. CONCLUSION: We did not find any advantage for allopurinol in the management of chronic prostatitis versus placebo in patients receiving routine antibacterial treatment.

    Objectives To determine the feasibility of conducting a randomized clinical trial designed to compare two methods of manual therapy (myofascial physical therapy (MPT) and global therapeutic massage (GTM)) among patients with urologic chronic pelvic pain syndromes. Materials and Methods Our goal was to recruit 48 subjects with chronic prostatitis/chronic pelvic pain syndrome or interstitial cystitis/painful bladder syndrome at six clinical centers. Eligible patients were randomized to either MPT or GTM and were scheduled to receive up to 10 weekly treatments, each 1 hour in duration. Criteria to assess feasibility included adherence of therapists to prescribed therapeutic protocol as determined by records of treatment, adverse events which occurred during study treatment, and rate of response to therapy as assessed by the Patient Global Response Assessment (GRA). Primary outcome analysis compared response rates between treatment arms using Mantel-Haenszel methods. Results Twenty-three (49%) men and 24 (51%) women were randomized over a six month period. Twenty-four (51%) patients were randomized to GTM, 23 (49%) to MPT; 44 (94%) patients completed the study. Therapist adherence to the treatment protocols was excellent. The GRA response rate of 57% in the MPT group was significantly higher than the rate of 21% in the GTM treatment group (p=0.03). Conclusions The goals to judge feasibility of conducting a full-scale trial of physical therapy methods were met. The preliminary findings of a beneficial effect of MPT warrants further study.

    Full Text Available Background/Aim: Oxidative stress plays a major role in the pathogenesis of pancreatitis. Antioxidant therapy in the form of high-dose vitamin has been used for the treatment of severe acute pancreatitis with equivocal results. We wished to evaluate the efficacy and safety of antioxidant (vitamin A, vitamin C, vitamin E therapy in patients with severe acute pancreatitis. Setting and design: This was a single-center, prospective, randomized, open-label with blinded endpoint assessment study of antioxidant therapy, conducted in the emergency department attached to our hospital. Materials and Methods: Thirty-nine patients with severe acute pancreatitis were randomly assigned to antioxidant treatment group (n=19 or a control group (n=20 within 96 hours of developing symptoms. Patients in the antioxidant group received antioxidants (vitamin A, vitamin E, vitamin C in addition to the standard treatment provided to both the groups for a period of 14 days. The primary outcome variable was presence of organ dysfunction at day 7. The secondary outcome variables were length of hospital stay, multiorgan dysfunction (MODS at day 7, recovery at the end of 4 weeks, complications, and mortality. The change in markers of oxidative stress from baseline was also measured. Results: We demonstrated no significant difference in organ dysfunction (P=1.0, MODS (P=0.8, and length of hospital stay (P=0.29 between the two groups. All the patients survived in the antioxidant-treated group, whereas two patients died in the control group. The change in the levels of malondialdehyde, superoxide dismutase, and reduced glutathione were not significantly different in the two groups at day 7. Univariate analysis showed marginal benefit with antioxidant treatment (P=0.034 in patients with severe acute pancreatitis. Conclusions: This randomized study demonstrates that there is no significant benefit from antioxidant therapy in patients with established severe acute pancreatitis.

    In 31 patients with pancreatitis, the amylase to creatinine clearance ratio (CACR) was significantly greater than for controls (10.7 +/- 1.7 vs. 2.6 +/- 0.3, P less than .001). Sixteen pancreatitis patients with serum amylase (SAm) within the normal range had a mean CACR significantly greater than that of 19 hospital control patients with normal SAm (9.2 +/- 1.5 vs. 3.0 +/- 0.4, P less than .001). For control patients a highly significant inverse correlation between SAm and CACR was observed. No relationship was detected between these parameters for pancreatitis patients. The results suggest that the CACR may be of aid in establishing the diagnosis of pancreatitis even in patients without hyperamylasemia.

    Full Text Available Abstract Background Human ß-defensins are a family of antimicrobial peptides located at the mucosal surface. Both sequence multi-site variations (MSV and copy-number variants (CNV of the defensin-encoding genes are associated with increased risk for various diseases, including cancer and inflammatory conditions such as psoriasis and acute pancreatitis. In a case–control study, we investigated the association between MSV in DEFB104 as well as defensin gene (DEF cluster copy number (CN, and pancreatic ductal adenocarcinoma (PDAC and chronic pancreatitis (CP. Results Two groups of PDAC (N=70 and CP (N=60 patients were compared to matched healthy control groups CARLA1 (N=232 and CARLA2 (N=160, respectively. Four DEFB104 MSV were haplotyped by PCR, cloning and sequencing. DEF cluster CN was determined by multiplex ligation-dependent probe amplification. Neither the PDAC nor the CP cohorts show significant differences in the DEFB104 haplotype distribution compared to the respective control groups CARLA1 and CARLA2, respectively. The diploid DEF cluster CN exhibit a significantly different distribution between PDAC and CARLA1 (Fisher’s exact test P=0.027, but not between CP and CARLA2 (P=0.867. Conclusion Different DEF cluster b CN distribution between PDAC patients and healthy controls indicate a potential protective effect of higher CNs against the disease.

    Background Chronic diseases, like diabetes mellitus, heart disease and cancer are leading causes of death and disability. These conditions are at least partially preventable or modifiable, e.g. by enhancing patients’ self-management. We aimed to examine the effectiveness of telephone-based health coaching (TBHC) in chronically ill patients. Methods and Findings This prospective, pragmatic randomized controlled trial compares an intervention group (IG) of participants in TBHC to a control group (CG) without TBHC. Endpoints were assessed two years after enrolment. Three different groups of insurees with 1) multiple conditions (chronic campaign), 2) heart failure (heart failure campaign), or 3) chronic mental illness conditions (mental health campaign) were targeted. The telephone coaching included evidence-based information and was based on the concepts of motivational interviewing, shared decision-making, and collaborative goal setting. Patients received an average of 12.9 calls. Primary outcome was time from enrolment until hospital readmission within a two-year follow-up period. Secondary outcomes comprised the probability of hospital readmission, number of daily defined medication doses (DDD), frequency and duration of inability to work, and mortality within two years. All outcomes were collected from routine data provided by the statutory health insurance. As informed consent was obtained after randomization, propensity score matching (PSM) was used to minimize selection bias introduced by decliners. For the analysis of hospital readmission and mortality, we calculated Kaplan-Meier curves and estimated hazard ratios (HR). Probability of hospital readmission and probability of death were analysed by calculating odds ratios (OR). Quantity of health service use and inability to work were analysed by linear random effects regression models. PSM resulted in patient samples of 5,309 (IG: 2,713; CG: 2,596) in the chronic campaign, of 660 (IG: 338; CG: 322) in the

    In nonrandomized trials, neoadjuvant treatment was reported to prolong survival in patients with pancreatic cancer. As neoadjuvant chemoradiation is established for the treatment of rectal cancer we examined the value of neoadjuvant chemoradiotherapy in pancreatic cancer in a randomized phase II trial. Radiological staging defining resectability was basic information prior to randomization in contrast to adjuvant therapy trials resting on pathological staging. Patients with resectable adenocarcinoma of the pancreatic head were randomized to primary surgery (Arm A) or neoadjuvant chemoradiotherapy followed by surgery (Arm B), which was followed by adjuvant chemotherapy in both arms. A total of 254 patients were required to detect a 4.33-month improvement in median overall survival (mOS). The trial was stopped after 73 patients; 66 patients were eligible for analysis. Twenty nine of 33 allocated patients received chemoradiotherapy. Radiotherapy was completed in all patients. Chemotherapy was changed in 3 patients due to toxicity. Tumor resection was performed in 23 vs. 19 patients (A vs. B). The R0 resection rate was 48 % (A) and 52 % (B, P = 0.81) and (y)pN0 was 30 % (A) vs. 39 % (B, P = 0.44), respectively. Postoperative complications were comparable in both groups. mOS was 14.4 vs. 17.4 months (A vs. B; intention-to-treat analysis; P = 0.96). After tumor resection, mOS was 18.9 vs. 25.0 months (A vs. B; P = 0.79). This worldwide first randomized trial for neoadjuvant chemoradiotherapy in pancreatic cancer showed that neoadjuvant chemoradiation is safe with respect to toxicity, perioperative morbidity, and mortality. Nevertheless, the trial was terminated early due to slow recruiting and the results were not significant. ISRCTN78805636; NCT00335543. (orig.)

    Full Text Available The efficacy of magnesium sulphate in chronic obstructive pulmonary disease (COPD was assessed by conducting a systematic review of published randomized clinical trials through extensive searches in MEDLINE and SCOPUS with no date limits, as well as manual review of journals. Outcome measures varied depending on route(s of administration of magnesium sulphate and medications co-administered. Risk of bias was evaluated and quality of evidence was graded. Four (4 randomized trials were included. All trials had a moderate risk of bias and were of average methodological quality. Magnesium sulphate given intravenously did not seem to have an immediate bronchodilatory effect; however it appears to potentiate the bronchodilatory effect of inhaled beta-2 agonists. Increase in peak expiratory flow rate (PEFR at 30 and 45 min was greater in those who received magnesium sulphate compared to placebo (P = 0.03, although the mean percentage change in PEFR was just 24%, without significant differences in dyspnoea scores, hospital admission rates, or emergency department readmission rates compared to placebo. Nebulized magnesium sulphate with salbutamol versus nebulized salbutamol with saline placebo showed no significant differences is forced expiratory volume in 1 s (FEV 1 measured at 90 min after adjustment for baseline FEV 1 (P = 0.34 or differences in the need for hospital admission. Combined inhalational and intravenous magnesium sulphate versus intravenous saline placebo and nebulized ipratropium bromide were comparable in terms of hospital admission, intubation and death, but the ipratropium bromide group showed better bronchodilator effect and improvement in arterial blood gas parameters. Overall, trial evidence for trial evidence for magnesium sulphate in acute exacerbation of COPD is poor, and further well-designed trials are needed.

    Full Text Available The U.S. Department of Health and Human Services vision and strategic framework on multiple chronic conditions (MCCs incorporates recommendations designed to facilitate research that will improve our knowledge about interventions and systems that will benefit individuals with MCCs (or multimorbidity. The evidence base supporting the management of patients with MCCs will be built both through intervention trials specifically designed to address multimorbidity and identification of MCCs in participants across the clinical trial range. This article specifically focuses on issues relating to external validity with specific reference to trials involving patients with MCCs. The exclusion of such patients from clinical trials has been well documented. Randomized control trials (RCTs are considered the “gold standard” of evidence, but may have drawbacks in relation to external validity, particularly in relation to multimorbidity. It may, therefore, be necessary to consider a broader range of research methods that can provide converging evidence on intervention effects to address MCCs. Approaches can also be taken to increase the usefulness of RCTs in general for providing evidence to inform multimorbidity management. Additional improvements to RCTs would include better reporting of inclusion and exclusion criteria and participant characteristics in relation to MCCs. New trials should be considered in terms of how they will add to the existing evidence base and should inform how interventions may work in different settings and patient groups. Research on treatments and interventions for patients with MCCs is badly needed. It is important that this research includes patient-centered measures and that generalizability issues be explicitly addressed.

    Pancreatic cancer exhibits an extraordinarily high level of resistance to almost any kind of systemic therapy evaluated in clinical trials so far. Therefore, the identification of novel therapeutic targets is urgently required. High-throughput screens have emerged as an important tool to identify putative targets for diagnosis and therapy in an unbiased manner. More than a decade ago, microarray technology was introduced to identify differentially expressed genes in pancreatic cancer as compared to normal pancreas, chronic pancreatitis and other cancer types located in close proximity to the pancreas. In addition, proteomic screens have facilitated the identification of differentially secreted proteins in body fluids of pancreatic cancer patients, serving as possible biomarkers. Recently, RNA interference-based loss-of-function screens have been used to identify functionally relevant genes, whose knock-down has impact on pancreatic cancer cell viability, thereby representing potential new targets for therapeutic intervention. This review summarizes recent results of transcriptional, proteomic and functional screens in pancreatic cancer and discusses potentials and limitations of the respective technologies as well as their impact on future therapeutic developments.

    Nightmares and sleep disturbance are fundamental concerns for victims of trauma. This study examined the efficacy of a manualized cognitive-behavioral treatment (CBT) for chronic nightmares in trauma-exposed individuals via a randomized clinical trial. Participants were randomly assigned to a treatment group or wait-list control group, with 27 participants completing the treatment. At the 6-month follow-up assessment, 84% of treated participants reported an absence of nightmares in the previous week. Significant decreases were also reported in symptoms of depression and posttraumatic stress, fear of sleep, and number of sleep problems, while sleep quality and quantity improved. The present study adds to the growing literature indicating this brief CBT as a first-line treatment for trauma-exposed individuals with chronic nightmares.

    Full Text Available NCIC Clinical Trials Group PA.3 was a randomized control trial that demonstrated improved overall survival (OS in patients receiving erlotinib in addition to gemcitabine for locally advanced or metastatic pancreatic cancer. Prior to therapy, patients had plasma samples drawn for future study. We sought to identify biomarkers within these samples.Using the proximity ligation assay (PLA, a probe panel was built from commercially available antibodies for 35 key proteins selected from a global genetic analysis of pancreatic cancers, and used to quantify protein levels in 20 uL of patient plasma. To determine if any of these proteins levels independently associated with OS, univariate and mulitbaraible Cox models were used. In addition, we examined the associations between biomarker expression and disease stage at diagnosis using Fisher's exact test. The correlation between Erlotinib sensitivity and each biomarkers was assessed using a test of interaction between treatment and biomarker.Of the 569 eligible patients, 480 had samples available for study. Samples were randomly allocated into training (251 and validation sets (229. Among all patients, elevated levels of interleukin-8 (IL-8, carcinoembryonic antigen (CEA, hypoxia-inducible factor 1-alpha (HIF-1 alpha, and interleukin-6 were independently associated with lower OS, while IL-8, CEA, platelet-derived growth factor receptor alpha and mucin-1 were associated with metastatic disease. Patients with elevated levels of receptor tyrosine-protein kinase erbB-2 (HER2 expression had improved OS when treated with erlotinib compared to placebo. In conclusion, PLA is a powerful tool for identifying biomarkers from archived, small volume serum samples. These data may be useful to stratify patient outcomes regardless of therapeutic intervention.ClinicalTrials.gov NCT00040183.

    Full Text Available Abdominal bloating is a common and bothersome symptom of chronic idiopathic constipation. The objective of this trial was to evaluate the efficacy and safety of linaclotide in patients with chronic idiopathic constipation and concomitant moderate-to-severe abdominal bloating.This Phase 3b, randomized, double-blind, placebo-controlled clinical trial randomized patients to oral linaclotide (145 or 290 μg or placebo once daily for 12 weeks. Eligible patients met Rome II criteria for chronic constipation upon entry with an average abdominal bloating score ≥5 (self-assessment: 0 10-point numerical rating scale during the 14-day baseline period. Patients reported abdominal symptoms (including bloating and bowel symptoms daily; adverse events were monitored. The primary responder endpoint required patients to have ≥3 complete spontaneous bowel movements/week with an increase of ≥1 from baseline, for ≥9 of 12 weeks. The primary endpoint compared linaclotide 145 μg vs. placebo.The intent-to-treat population included 483 patients (mean age=47.3 years, female=91.5%, white=67.7%. The primary endpoint was met by 15.7% of linaclotide 145 μg patients vs. 7.6% of placebo patients (P<0.05. Both linaclotide doses significantly improved abdominal bloating vs. placebo (P<0.05 for all secondary endpoints, controlling for multiplicity. Approximately one-third of linaclotide patients (each group had ≥50% mean decrease from baseline in abdominal bloating vs. 18% of placebo patients (P<0.01. Diarrhea was reported in 6% and 17% of linaclotide 145 and 290 μg patients, respectively, and 2% of placebo patients. AEs resulted in premature discontinuation of 5% and 9% of linaclotide 145 μg and 290 μg patients, respectively, and 6% of placebo patients.Once-daily linaclotide (145 and 290 μg significantly improved bowel and abdominal symptoms in chronic idiopathic constipation patients with moderate-to-severe baseline abdominal bloating; in particular

    Full Text Available Functionally, the pancreas consists of two types of tissues: exocrine and endocrine. Exocrine pancreatic disorders mainly involve acute and chronic pancreatitis. Acute pancreatitis typically is benign, while chronic pancreatitis is considered a risk factor for developing pancreatic cancer. Pancreatic carcinoma is the fourth leading cause of cancer related deaths worldwide. Most pancreatic cancers develop in the exocrine tissues. Endocrine pancreatic tumors are more uncommon, and typically are less aggressive than exocrine tumors. However, the endocrine pancreatic disorder, diabetes, is a dominant cause of morbidity and mortality. Importantly, different growth factors and their receptors play critical roles in pancreatic pathogenesis. Hence, an improved understanding of how various growth factors affect pancreatitis and pancreatic carcinoma is necessary to determine appropriate treatment. This chapter describes the role of different growth factors such as vascular endothelial growth factor (VEGF, insulin-like growth factor (IGF, platelet derived growth factor (PDGF, fibroblast growth factor (FGF, epidermal growth factor (EGF, and transforming growth factor (TGF in various pancreatic pathophysiologies. Finally, the crosstalk between different growth factor axes and their respective signaling mechanisms, which are involved in pancreatitis and pancreatic carcinoma, are also discussed.

    Hereditary pancreatitis is an autosomal dominant disease with incomplete penetrance (80%), accounting for approximately 1% of all cases of pancreatitis. It is characterized by the onset of recurrent attacks of acute pancreatitis in childhood and frequent progression to chronic pancreatitis. Whitcomb et al. identified the cationic trypsinogen gene (PRSS1) on chromosome 7q35 as the site of the mutation that causes hereditary pancreatitis. The European registry of hereditary pancreatitis and familial pancreatic cancer (EUROPAC) aims to identify and make provisions for those affected by hereditary pancreatitis and familial pancreatic cancer. The most common mutations in hereditary pancreatitis are R122H, N29I and A16V but many families have been described with clinically defined hereditary pancreatitis where there is no PRSS1 mutation. It is known that the cumulative lifetime risk (to age 70 years) of pancreatic cancer is 40% in individuals with hereditary pancreatitis. This subset of individuals form an ideal group for the development of a screening programme aimed at detecting pancreatic cancer at an early stage in an attempt to improve the presently poor long-term survival. Current screening strategies involve multimodality imaging (computed tomography, endoluminal ultrasound) and endoscopic retrograde cholangiopancreatography for pancreatic juice collection followed by molecular analysis of the DNA extracted from the juice. The potential benefit of screening (curative resection) must be balanced against the associated morbidity and mortality of surgery. Philosophically, the individual's best interest must be sought in light of the latest advances in medicine and science following discussions with a multidisciplinary team in specialist pancreatic centres.

    2006-12-01

    Full Text Available Abstract Background Acupuncture is increasingly being used for many conditions including chronic neck pain. However the evidence remains inconclusive, indicating the need for further well-designed research. The aim of this study was to conduct a pilot randomised controlled parallel arm trial, to establish key features required for the design and implementation of a large-scale trial on acupuncture for chronic neck pain. Methods Patients whose GPs had diagnosed neck pain were recruited from one general practice, and randomised to receive usual GP care only, or acupuncture (up to 10 treatments over 3 months as an adjunctive treatment to usual GP care. The primary outcome measure was the Northwick Park Neck Pain Questionnaire (NPQ at 3 months. The primary analysis was to determine the sample size for the full scale study. Results Of the 227 patients with neck pain identified from the GP database, 28 (12.3% consenting patients were eligible to participate in the pilot and 24 (10.5% were recruited to the trial. Ten patients were randomised to acupuncture, receiving an average of eight treatments from one of four acupuncturists, and 14 were randomised to usual GP care alone. The sample size for the full scale trial was calculated from a clinically meaningful difference of 5% on the NPQ and, from this pilot, an adjusted standard deviation of 15.3%. Assuming 90% power at the 5% significance level, a sample size of 229 would be required in each arm in a large-scale trial when allowing for a loss to follow-up rate of 14%. In order to achieve this sample, one would need to identify patients from databases of GP practices with a total population of 230,000 patients, or approximately 15 GP practices roughly equal in size to the one involved in this study (i.e. 15,694 patients. Conclusion This pilot study has allowed a number of recommendations to be made to facilitate the design of a large-scale trial, which in turn will help to clarify the existing evidence

    Full Text Available A recent genome-wide association study (GWAS identified association with variants in X-linked CLDN2 and MORC4, and PRSS1-PRSS2 loci with chronic pancreatitis (CP in North American patients of European ancestry. We selected 9 variants from the reported GWAS and replicated the association with CP in Indian patients by genotyping 1807 unrelated Indians of Indo-European ethnicity, including 519 patients with CP and 1288 controls. The etiology of CP was idiopathic in 83.62% and alcoholic in 16.38% of 519 patients. Our study confirmed a significant association of 2 variants in CLDN2 gene (rs4409525-OR 1.71, P = 1.38 x 10-09; rs12008279-OR 1.56, P = 1.53 x 10-04 and 2 variants in MORC4 gene (rs12688220-OR 1.72, P = 9.20 x 10-09; rs6622126-OR 1.75, P = 4.04x10-05 in Indian patients with CP. We also found significant association at PRSS1-PRSS2 locus (OR 0.60; P = 9.92 x 10-06 and SAMD12-TNFRSF11B (OR 0.49, 95% CI [0.31-0.78], P = 0.0027. A variant in the gene MORC4 (rs12688220 showed significant interaction with alcohol (OR for homozygous and heterozygous risk allele -14.62 and 1.51 respectively, P = 0.0068 suggesting gene-environment interaction. A combined analysis of the genes CLDN2 and MORC4 based on an effective risk allele score revealed a higher percentage of individuals homozygous for the risk allele in CP cases with 5.09 fold enhanced risk in individuals with 7 or more effective risk alleles compared with individuals with 3 or less risk alleles (P = 1.88 x 10-14. Genetic variants in CLDN2 and MORC4 genes were associated with CP in Indian patients.

    This article presents current MR imaging techniques for the pancreas, and review a spectrum of MR imaging features of various pancreatic diseases. These include: 1) congenital anomalies such as anomalous union of pancreatobiliary ducts, divisum, and annular pancreas, 2) inflammatory diseases, including acute or chronic pancreatitis with complications, groove pancreatitis, and autoimmune pancreatitis, tumor-forming pancreatitis, 3) pancreatic neoplasms, including adenocarcinoma, islet cell tumors, and cystic neoplasms (microcystic adenoma, mucinous cystic neoplasms, and intraductal mucin-producing pancreatic tumor). Particular attention is paid to technical advances in MR imaging of the pancreas such as fat-suppression, MR pancreatography (single- or multi-slice HASTE), and thin-section 3D multiphasic contrast-enhanced dynamic sequences. Imaging characteristics that may lead to a specific diagnosis or narrow the differential diagnosis are also discussed.

    AIM: To summarize progress in the study of K-ras gene studies in pancreatic cancer and its potential clinical significance in screening test for early detection of pancreatic cancer, and to differentiate pancreatic cancer from chronic pancreatitis in recent decade.METHODS: Literature search (MEDLINE 1986-2003) was performed using the key words K-ras gene, pancreatic cancer, chronic pancreatitis, and diagnosis. Two kind of opposite points of view on the significance of K-ras gene in detection early pancreatic cancer and differentiation pancreatic cancer from chronic pancreatitis were investigated.The presence of a K-ras gene mutation at codon 12 has been seen in 75-100% of pancreatic cancers, and is not rare in patients with chronic pancreatitis, and represents an increased risk of developing pancreatic cancer. However, the significance of the detection of this mutation in specimens obtained by needle aspiration from pure pancreatic juice and from stools for its utilization for the detection of early pancreatic cancer, and differentiation pancreatic cancer from chronic pancreatitis remains controversial. CONCLUSION: The value of K-ras gene mutation for the detection of early pancreatic cancer and differentiation pancreatic cancer from chronic pancreatitis remains uncertains in clinical pratice. Nevertheless, K-ras mutation screening may increase the sensitivity of FNA and ERP cytology and may be useful in identifying pancreatitis patients at high risk for developing cancer, and as a adjunct with cytology to differentiate pancreatic cancer from chronic pancreatitis.

    Full Text Available AbstractMelodic Intonation Therapy (MIT is a language production therapy for severely non-fluent aphasic patients using melodic intoning and rhythm to restore language. Although many studies have reported its beneficial effects on language production, randomized controlled trials (RCT examining the efficacy of MIT are rare. In an earlier publication, we presented the results of an RCT on MIT in subacute aphasia and found that MIT was effective on trained and untrained items. Further, we observed a clear trend in improved functional language use after MIT. Subacute aphasic patients receiving MIT improved considerably on language tasks measuring connected speech and daily life verbal communication. Here, we present the results of a pilot RCT on MIT in chronic aphasia and compare these to the results observed in subacute aphasia. We used a multicenter waiting-list randomized controlled trial design. Patients with chronic (>1 year post-stroke aphasia were randomly allocated to the experimental group (6 weeks MIT or to the control group (6 weeks no intervention followed by 6 weeks MIT. Assessments were done at baseline (T1, after 6 weeks (T2, and 6 weeks later (T3. Efficacy was evaluated at T2 using univariable linear regression analyses. Outcome measures were chosen to examine several levels of therapy success: improvement on trained items, generalization to untrained items, and generalization to verbal communication. Of 17 included patients, 10 were allocated to the experimental condition and 7 to the control condition. MIT significantly improved repetition of trained items (β=13.32, p=.02. This effect did not remain stable at follow-up assessment. In contrast to earlier studies, we found only a limited and temporary effect of MIT, without generalization to untrained material or to functional communication. The results further suggest that the effect of MIT in chronic aphasia is more restricted than its effect in earlier stages post stroke. This

    Full Text Available Abstract Background Chronic back pain is a major public health problem and the primary reason patients seek acupuncture treatment. Therefore, an objective assessment of acupuncture efficacy is critical for making informed decisions about its appropriate role for patients with this common condition. This study addresses methodological shortcomings that have plagued previous studies evaluating acupuncture for chronic low back pain. Methods and Design A total of 640 participants (160 in each of four arms between the ages of 18 and 70 years of age who have low back pain lasting at least 3 months will be recruited from integrated health care delivery systems in Seattle and Oakland. They will be randomized to one of two forms of Traditional Chinese Medical (TCM acupuncture needling (individualized or standardized, a "control" group (simulated acupuncture, or to continued usual medical care. Ten treatments will be provided over 7 weeks. Study participants and the "Diagnostician" acupuncturists who evaluate participants and propose individualized treatments will be masked to the acupuncture treatment actually assigned each participant. The "Therapist" acupuncturists providing the treatments will not be masked but will have limited verbal interaction with participants. The primary outcomes, standard measures of dysfunction and bothersomeness of low back pain, will be assessed at baseline, and after 8, 26, and 52 weeks by telephone interviewers masked to treatment assignment. General health status, satisfaction with back care, days of back-related disability, and use and costs of healthcare services for back pain will also be measured. The primary analysis comparing outcomes by randomized treatment assignment will be analysis of covariance adjusted for baseline value. For both primary outcome measures, this trial will have 99% power to detect the presence of a minimal clinically significant difference among all four treatment groups and over 80% power for

    Objective To study the metabolite features of acute necrotizing pancreatitis (ANP) and chronic pancreatitis (CP) in rats.Methods A total of 22 Wistar rats were divided into ANP group (n =7 ),CP group (n =6) and the control group (n =9).ANP model was induced peritoneous injection of 20% Larginine,and the rats were sacrificed 12 hours later.CP model was induced by intravenously injection of DBTC (8 mg/kg body weight),and the rats were sacrificed after 2 months.The rats in the control group received same amount of saline.Serum amylase was determined and pancreatic tissues were pathologically examined.Metabolic changes of pancreatic tissues in vitro were studied by high resolution magic angle spinning nuclear magnetic resonance (MAS NMR ),and analyzed by using principal components analysis (PCA).Characteristic metabolites of ANP and CP were compared. Results Compared with the control group,increased leucine,iso-leucine and valine levels were observed in ANP group,however,the opposite trends were observed in CP group.Phosphocholine,glycerophosphocholine,choline levels were increased and fatty acids,lactate,betaine,glycine levels were decreased in both ANP and CP groups.The lipid content in CP group were significantly higher than that in ANP group and the increased taurine was only observed in CP group. Conclusions There were obvious metabolic features in pancreatic tissue in rats with pancreatitis disorders,and the increased taurine could be used as biomarker to discriminate ANP and CP.%目的 用代谢组学方法研究大鼠胰腺组织代谢特征,以期发现胰腺炎症的标记性代谢物.方法 Wistar大鼠22只,按数字表法随机分成急性坏死性胰腺炎组(ANP,7只)、慢性胰腺炎组(CP,6只)和对照组(9只).ANP组经腹腔注射20%L-精氨酸溶液制模;CP组经尾静脉注射二丁基二氯基锡(DBTC)溶液制模;对照组注射等量生理盐水.检测血清淀粉酶含量,胰腺组织行病理学检查.利用高分辨魔角旋转核
