    Full Text Available Background: Optimized RNA extraction from tissues and cell lines consists of four main stages regardless of the method of extraction: 1 homogenizing, 2 effective denaturation of proteins from RNA, 3 inactivation of ribonuclease, and 4 removal of any DNA, protein, and carbohydrate contamination. Isolation of undamaged intact RNA is challenging when the related tissue contains high levels of RNase. Various technical difficulties occur during extraction of RNA from pancreatic tissue due to spontaneous autolysis. Since standard routine protocols yield unacceptable results in pancrease, we have designed a simple method for RNA extraction by comparing different protocols. Methods: We obtained 20-30 mg pancreatic tissues in less than 2 min from 30 rats. Several methods were performed to extract RNA from pancreatic tissue and evaluate its integrity. All methods were performed three times to obtain reproducible results. Results: Immersing pancreatic tissue in RNA-later for 24 h at -80ºC yielded high quality RNA by using the TriPure reagent which was comparable to the commercial RNeasy Micro Kit. The quality of RNA was evaluated by spectrophotometer, electrophoresis and RT-PCR. We separated intact 28S and 18S ribosomal RNA (rRNA when our procedure was compared with the RNeasy Micro Kit. Finally, full length of the actin gene was amplified by RT-PCR. Conclusion: We designed a simple, fast, cost-effective method for complete RNA extraction from the least amount of quantitatively intact pancreatic tissue

    Objective: Antioxidant, anti-inflammatory, analgesic and antimicrobial activities of Tribulus terrestris (T. terrestris) could be helpful in the treatment of acute pancreatitis; thus, this study was designed to investigate the effects of T. terrestris on cerulein-induced acute pancreatitis in mice. Materials and Methods: Three doses (100, 200 and 400 mg/kg) of T. terrestris hydro-alcoholic extract were administered both orally (60 minutes before pancreatitis induction, p.o.) and intra-peritoneally (30 minutes before pancreatitis induction, i.p.) to different groups of mice (n=6). Pancreatitis was induced by five injections (i.p.) of cerulein 50μg/kg body weight with 1 hr intervals. Animals were euthanized 5 hr after the last injection of cerulein and tissue injures were assessed biochemically and pathologically. Results: T. terrestris extract 200 and 400mg/kg (p.o.) and T. terrestris extract 400 mg/kg (i.p.) reduced pancreatic tissue myeloperoxidase (MPO) activity and serum amylase and lipase levels and alleviated histological parameters. Conclusion: These data suggest that T. terrestris hydro-alcoholic extract was effective in protecting against experimental acute pancreatitis and possibly the efficacy depends on dose and route of administration.

    The aim of this study is to search new anti-obesity and anti-diabetic agents from plant and spices crude extracts as alternative to synthetic drugs. The inhibitory effect of 72 extracts was evaluated, in vitro, on lipase and amylase activities. Aqueous extracts of cinnamon and black tea exhibited an appreciable inhibitory effect on pancreatic amylase with IC 50 values of 18 and 87 μg, respectively. Aqueous extracts of cinnamon and mint showed strong inhibitory effects against pancreatic lipase with IC 50 of 45 and 62 μg, respectively. The presence of bile salts and colipase or an excess of interface failed to restore the lipase activity. Therefore, the inhibition of pancreatic lipase, by extracts of spices and plants, belongs to an irreversible inhibition. Crude extract of cinnamon showed the strongest anti-lipase and anti-amylase activities which offer a prospective therapeutic approach for the management of diabetes and obesity.

    Full Text Available Diabetes mellitus is associated with reductions in glutathione, supporting the critical role of oxidative stress in its pathogenesis. Antioxidant food components such as flavonoids have a protective role against oxidative stress-induced degenerative and age-related diseases. Flavonoids constitute an important part of the human diet; they can be found in most plant foods, including green tea, grapes or cocoa and possess multiple biological activities. This study investigates the chemo-protective effect of a cocoa phenolic extract (CPE containing mainly flavonoids against oxidative stress induced by tert-butylhydroperoxide (t-BOOH on Ins-1E pancreatic beta cells. Cell viability and oxidative status were evaluated. Ins-1E cells treatment with 5–20 μg/mL CPE for 20 h evoked no cell damage and did not alter ROS production. Addition of 50 μM t-BOOH for 2 h increased ROS and carbonyl groups content and decreased reduced glutathione level. Pre-treatment of cells with CPE significantly prevented the t-BOOH-induced ROS and carbonyl groups and returned antioxidant defences to adequate levels. Thus, Ins-1E cells treated with CPE showed a remarkable recovery of cell viability damaged by t-BOOH, indicating that integrity of surviving machineries in the CPE-treated cells was notably protected against the oxidative insult.

    Acute pancreatitis is the acute inflammation of pancreas and peripancreatic tissues, and distant organs are also affected. The aim of this study was to investigate the effect of Urtica dioica extract (UDE) treatment on cerulein induced acute pancreatitis in rats. Twenty-one Wistar Albino rats were divided into three groups: Control, Pancreatitis, and UDE treatment group. In the control group no procedures were performed. In the pancreatitis and treatment groups, pancreatitis was induced with intraperitoneal injection of cerulein, followed by intraperitoneal injection of 1 ml saline (pancreatitis group) and 1 ml 5.2% UDE (treatment group). Pancreatic tissues were examined histopathologically. Pro-inflammatory cytokines (tumor necrosis factor-α), amylase and markers of apoptosis (M30, M65) were also measured in blood samples. Immunohistochemical staining was performed with Caspase-3 antibody. Histopathological findings in the UDE treatment group were less severe than in the pancreatitis group (5.7 vs 11.7, p = 0.010). TNF-α levels were not statistically different between treated and control groups (63.3 vs. 57.2, p = 0.141). UDE treatment was associated with less apoptosis [determined by M30, caspase-3 index (%)], (1.769 vs. 0.288, p = 0.056; 3% vs. 2.2%, p = 0.224; respectively). UDE treatment of pancreatitis merits further study.

    The leaves of Morus alba (Moraceae) have been traditionally used for the treatment of metabolic diseases including diabetes and hyperlipidemia. Thus, inhibitory effect of M. alba leaves on pancreatic lipase and their active constituents were investigated in this study. Twenty phenolic compounds including ten flavonoids, eight benzofurans, one stilbene and one chalcones were isolated from the leaves of M. alba. Among the isolated compounds, morachalcone A (20) exerted strong pancreatic lipase inhibition with IC50 value of 6.2 μM. Other phenolic compounds containing a prenyl group showed moderate pancreatic lipase inhibition with IC50 value of <50 μM. Next, extraction conditions with maximum pancreatic lipase inhibition and phenolic content were optimized using response surface methodology with three-level-three-factor Box-Behnken design. Our results suggested the optimized extraction condition for maximum pancreatic lipase inhibition and phenolic content as ethanol concentration of 74.9%; temperature 57.4 °C and sample/solvent ratio, 1/10. The pancreatic lipase inhibition and total phenolic content under optimized condition were found to be 58.5% and 26.2 μg GAE (gallic acid equivalent)/mg extract, respectively, which were well matched with the predicted value.

    Grapefruit seed extract (GSE) has been shown to exert antibacterial, antifungal and antioxidant activity possibly due to the presence of naringenin, the flavonoid with cytoprotective action on the gastric mucosa. No study so far has been undertaken to determine whether this GSE is also capable of preventing acute pancreatic damage induced by ischemia/reperfusion (I/R), which is known to result from reduction of anti-oxidative capability of pancreatic tissue, and whether its possible preventive effect involves an antioxidative action of this biocomponent. In this study carried out on rats with acute hemorrhagic pancreatitis induced by 30 min partial pancreatic ischemia followed by 6 h of reperfusion, the GSE or vehicle (vegetable glycerin) was applied intragastrically in gradually increasing amounts (50-500 microl) 30 min before I/R. Pretreatment with GSE decreased the extent of pancreatitis with maximal protective effect of GSE at the dose 250 microl. GSE reduced the pancreatitis-evoked increase in serum lipase and poly-C specific ribonuclease activity, and attenuated the marked fall in pancreatic blood flow and pancreatic DNA synthesis. GSE administered alone increased significantly pancreatic tissue content of lipid peroxidation products, malondialdehyde and 4-hydroxyalkens, and when administered before I/R, GSE reduced the pancreatitis-induced lipid peroxidation. We conclude that GSE exerts protective activity against I/R-induced pancreatitis probably due to the activation of antioxidative mechanisms in the pancreas and the improvement of pancreatic blood flow.

    Cholesterol control is fundamental for prevention of cardiovascular disorders. In this work, the hypocholesterolemic activity of an aqueous Opuntia ficus-indica extract (AOE) was tested in triton-induced mice. The inhibitory activity on pancreatic lipase enzyme was evaluated in vitro by the same extract. Furthermore, polyphenol content of the extract was evaluated. Hypercholesterolemia was induced in three groups of mice by intraperitoneal administration of Triton WR-1339. After induction of hypercholesterolemia, the groups were treated with an AOE (500 mg/kg) and saline solution and the positive control group with orlistat, respectively. Cholesterol levels were measured 24 h later in peripheral blood. The levels of blood cholesterol after administration of AOE significantly decreased compared to negative control. The inhibitory activity of AOE on pancreatic lipase enzyme was evaluated at concentrations from 60 to 1000 μg/mL. The AOE inhibited the pancreatic lipase with an IC50 = 588.5 μg/mL. The AOE had a high content of polyphenolic compounds. These results show that AOE is able to prevent hypercholesterolemia by pancreatic lipase inhibition, in part due to its polyphenolic compounds.

    Background Kaempferol is one of the most important constituents in ginkgo flavonoids. Recent studies indicate kaempferol may have anti-tumor activities. The objective in this study was to determine the effect and mechanisms of kaempferol on pancreatic cancer cell proliferation and apoptosis. Materials and Methods Pancreatic cancer cell lines MIA PaCa-2 and Panc-1 were treated with Kampferol, and the inhibitory effects of kaempferol on pancreatic cancer cell proliferation were examined by direct cell counting, 3H-thymidine incorporation and MTS assay. Lactate dehydrogenase (LDH) release from cells was determined as an index of cytotoxicity. Apoptosis was analyzed by TUNEL assay. Results Upon the treatment with 70 μM kaempferol for 4 days, MIA PaCa-2 cell proliferation was significantly inhibited by 79% and 45.7% as determined by direct cell counting and MTS assay, respectively, compared with control cells (Pkaempferol significantly inhibited Panc-1 cell proliferation. Kaempferol treatment also significantly reduced 3H-thymidine incorporation in both MIA PaCa-2 and Panc-1 cells. Combination treatment of low concentrations of kaempferol and 5-fluorouracil (5-FU) showed an additive effect on the inhibition of MIA PaCa-2 cell proliferation. Furthermore, kaempferol had a significantly less cytotoxicity than 5-FU in normal human pancreatic ductal epithelial cells (P=0.029). In both MIA PaCa-2 and Panc-1 cells, apoptotic cell population was increased when treated with kaempferol in a concentration-dependent manner. Conclusions Ginkgo biloba extract kaempferol effectively inhibits pancreatic cancer cell proliferation and induces cancer cell apoptosis, which may sensitize pancreatic tumor cells to chemotherapy. Kaempferol may have clinical applications as adjuvant therapy in the treatment of pancreatic cancer. PMID:18570926

    Full Text Available Abstract Background There has been a long standing interest in the identification of medicinal plants and derived natural products for developing cancer therapeutics. Our study focuses upon pancreatic cancer, due to its high mortality rate, that is attributed in part to the lack of an effective chemotherapeutic agent. Previous reports on the use of medicinal plant extracts either alone or alongside conventional anticancer agents in the treatment of this cancer have shown promising results. This work aims to investigate the therapeutic properties of a library of medicinal plants from Bangladesh. Methods 56 extracts of 44 unique medicinal plants were studied. The extracts were screened for cytotoxicity against the pancreatic adenocarcinoma cell line Panc-1, using a label-free biosensor assay. The top cytotoxic extracts identified in this screen were tested on two additional pancreatic cancer cell lines (Mia-Paca2 and Capan-1 and a fibroblast cell line (Hs68 using an MTT proliferation assay. Finally, one of the most promising extracts was studied using a caspase-3 colorimetric assay to identify induction of apoptosis. Results Crude extracts of Petunia punctata, Alternanthera sessilis, and Amoora chittagonga showed cytotoxicity to three cancer cell lines with IC50 values ranging between 20.3 - 31.4 μg/mL, 13.08 - 34.9 μg/mL, and 42.8 - 49.8 μg/mL, respectively. Furthermore, treatment of Panc-1 cells with Petunia punctata was shown to increase caspase-3 activity, indicating that the observed cytotoxicity was mediated via apoptosis. Only Amoora chittagonga showed low cytotoxicity to fibroblast cells with an IC50 value > 100 μg/mL. Conclusion Based upon the initial screening work reported here, further studies aimed at the identification of active components of these three extracts and the elucidation of their mechanisms as cancer therapeutics are warranted.

    Moringa stenopetala has been used in traditional health systems to treat diabetes mellitus. One of the successful methods to prevent of the onset of diabetes is to control postprandial hyperglycemia by the inhibition of α-glucosidase and pancreatic α-amylase activities, resulting in the aggressive delay of the carbohydrate digestion of absorbable monosaccharides. The aim of the present study is to investigate the effect of the extract of the leaves of Moringa stenopetala on α-glucosidase, pancreatic α-amylase, pancreatic lipase, and pancreatic cholesterol esterase activities, and, therefore find out the relevance of the plant in controlling blood sugar and lipid levels. The dried leaves of Moringa stenopetala were extracted with hydroalcoholic solvent and dried using rotary vapor under reduced pressure. The dried extracts were determined for the total phenolic compounds, flavonoid content and condensed tannins content by using Folin-Ciocateu's reagent, AlCl3 and vanillin assay, respectively. The dried extract of plant-based food was further quantified with respect to intestinal α-glucosidase (maltase and sucrase) inhibition and pancreatic α-amylase inhibition by glucose oxidase method and dinitrosalicylic (DNS) reagent, respectively. The phytochemical analysis indicated that flavonoid, total phenolic, and condensed tannin contents in the extract were 71.73 ± 2.48 mg quercetin equivalent/g of crude extract, 79.81 ± 2.85 mg of gallic acid equivalent/g of crude extract, 8.82 ± 0.77 mg catechin equivalent/g of crude extract, respectively. The extract inhibited intestinal sucrase more than intestinal maltase with IC50 value of 1.47 ± 0.19 mg/ml. It also slightly inhibited pancreatic α-amylase, pancreatic lipase and pancreatic cholesterol esterase. The result demonstrated the beneficial biochemical effects of Moringa stenopetala by inhibiting intestinal α-glucosidase, pancreatic cholesterol esterase and pancreatic lipase activities. A

    Full Text Available Objective: To analyze K-ras gene from induced pancreatic cancer rats administered with Momordicacharantia and Ocimumbasilicum leaf extracts. Methods: Twenty-five (25 adult rats weighing between 90–120 g were divided into 5 groups namely RA, RB, RC, NC and PC, each group had 5 rats. The PC which served as the control was fed with normal fish meal and water ad libitum; the NC which is the negative control received 20 mg/ml/week of Nitrosamines only while other groups received different concentrations of aqueous extract of both M. charantia and O. basilicum (200 mg, 100 mg, 50 mg and Nitrosamine. Qualitative phytochemical screening of the aqueous extract of both M. charantia and O. basilicum was carried out. The extraction of DNA was done using Jena Bioscience DNA preparation kit and the protocol was based on the spin column based genomic DNA purification from blood, animal and plant cells. Agarose gel electrophoresis was used to analyze the K-ras gene extracted from the pancreas tissues of experimental rats while hematoxylinand eosin staining was used for histological assay. Results: Phytochemical screening revealed the presence of alkaloids, tannins, flavonoids, saponins and glycosides in M. charantia while saponins, tannins and glycosides were discovered in O. basilicum. Significant reduction in the weight of rats treated with 200 mg of aqueous extracts of M. charantia and O. basilicum while rats that were dosed with nitrosamines only showed a slight increase in weight in the first three weeks when compared to the positive control. Histological studies revealed that there is both enlargement and reduction in the islet cell size, with one of the sections showing a normal islet cell size. While the agarose gel electrophoresis revealed that there may be possibility of prevention of damage to k-ras gene as a result of the effect of plants extract. Conclusion: This work has shown that the leaf extracts of both M. charantia and O. basilicum

    Full Text Available Endophytic Streptomyces sp. AEBg12 isolated from Zingiber cassumunar (Bangle is known to produce pancreatic lipase inhibitory compound. However, the characteristics of this active compound has not been reported yet. This study aimed to determine the characteristics of pancreatics inhibitory compound produced by Streptomyces sp. AEBg12 and to assess the role of endophytic actinobacteria in producing pancreatic lipase inhibitor using endophytic-free bangle tissue culture, wild bangle and compared with the activity of Streptomyces sp. AEBg12 endophytes. Supernatant of Streptomyces sp. AEBg12 was extracted using ethanol, ethyl acetate, and n-hexane solvents. Toxicity test was performed using larvae of shrimp Artemia salina. The results showed that the best solvent to obtain pancreatic lipase inhibitor compounds was ethanol. Phytochemical analysis showed that ethanolic extract of endophytic Streptomyces sp. AEBg12 contained flavonoids. IC50 value of ethanol extract was 180.83 µg/ml. The result of TLC showed that ethanolic extract of Streptomyces AEBg12 had a blue luminescence band indicated that there were either flavone, flavanones, flavonols or isoflavones. Inhibitory activity of Streptomyces sp. AEBg12 was higher than wild bangle and bangle tissue culture. The information from this study can be be used as a basic data for further characterization of the active compound, which might be developed as an antiobesity agent through its pancreatic lipase inhibitory activity.

    2004-01-01

    Porcine pancreatic alpha-amylase (PPA) was allowed to react with herbal extracts containing rosmarinic acid (RA) and purified RA. The derivatized enzyme-phytochemical mixtures obtained were characterized for residual amylase activity. These in vitro experiments showed that the amylase activity was inhibited in the presence of these phytochemicals. The extent of amylase inhibition correlated with increased concentration of RA. RA-containing oregano extracts yielded higher than expected amylase inhibition than similar amount of purified RA, suggesting that other phenolic compounds or phenolic synergies may contribute to additional amylase inhibitory activity. The significance of food-grade, plant-based amylase inhibitors for modulation of diabetes mellitus and other oxidation-linked diseases is hypothesized and discussed.

    Olea europaea L. leaves are an agricultural waste product with a high concentration of phenolic compounds; especially oleuropein. Oleuropein has been shown to exhibit anti-proliferative activity against a number of cancer types. However, they have not been tested against pancreatic cancer, the fifth leading cause of cancer related death in Western countries. Therefore, water, 50% ethanol and 50% methanol extracts of Corregiola and Frantoio variety Olea europaea L. leaves were investigated for their total phenolic compounds, total flavonoids and oleuropein content, antioxidant capacity and anti-proliferative activity against MiaPaCa-2 pancreatic cancer cells. The extracts only had slight differences in their phytochemical properties, and at 100 and 200 μg/mL, all decreased the viability of the pancreatic cancer cells relative to controls. At 50 μg/mL, the water extract from the Corregiola leaves exhibited the highest anti-proliferative activity with the effect possibly due to early eluting HPLC peaks. For this reason, olive leaf extracts warrant further investigation into their potential anti-pancreatic cancer benefits.

    The extract of ginger (Zingiber officinale Roscoe) and its major pungent components, [6]-shogaol and [6]-gingerol, have been shown to have an anti-proliferative effect on several tumor cell lines. However, the anticancer activity of the ginger extract in pancreatic cancer is poorly understood. Here, we demonstrate that the ethanol-extracted materials of ginger suppressed cell cycle progression and consequently induced the death of human pancreatic cancer cell lines, including Panc-1 cells. The underlying mechanism entailed autosis, a recently characterized form of cell death, but not apoptosis or necroptosis. The extract markedly increased the LC3-II/LC3-I ratio, decreased SQSTM1/p62 protein, and enhanced vacuolization of the cytoplasm in Panc-1 cells. It activated AMPK, a positive regulator of autophagy, and inhibited mTOR, a negative autophagic regulator. The autophagy inhibitors 3-methyladenine and chloroquine partially prevented cell death. Morphologically, however, focal membrane rupture, nuclear shrinkage, focal swelling of the perinuclear space and electron dense mitochondria, which are unique morphological features of autosis, were observed. The extract enhanced reactive oxygen species (ROS) generation, and the antioxidant N-acetylcystein attenuated cell death. Our study revealed that daily intraperitoneal administration of the extract significantly prolonged survival (P = 0.0069) in a peritoneal dissemination model and suppressed tumor growth in an orthotopic model of pancreatic cancer (P < 0.01) without serious adverse effects. Although [6]-shogaol but not [6]-gingerol showed similar effects, chromatographic analyses suggested the presence of other constituent(s) as active substances. Together, these results show that ginger extract has potent anticancer activity against pancreatic cancer cells by inducing ROS-mediated autosis and warrants further investigation in order to develop an efficacious candidate drug.

    Full Text Available The extract of ginger (Zingiber officinale Roscoe and its major pungent components, [6]-shogaol and [6]-gingerol, have been shown to have an anti-proliferative effect on several tumor cell lines. However, the anticancer activity of the ginger extract in pancreatic cancer is poorly understood. Here, we demonstrate that the ethanol-extracted materials of ginger suppressed cell cycle progression and consequently induced the death of human pancreatic cancer cell lines, including Panc-1 cells. The underlying mechanism entailed autosis, a recently characterized form of cell death, but not apoptosis or necroptosis. The extract markedly increased the LC3-II/LC3-I ratio, decreased SQSTM1/p62 protein, and enhanced vacuolization of the cytoplasm in Panc-1 cells. It activated AMPK, a positive regulator of autophagy, and inhibited mTOR, a negative autophagic regulator. The autophagy inhibitors 3-methyladenine and chloroquine partially prevented cell death. Morphologically, however, focal membrane rupture, nuclear shrinkage, focal swelling of the perinuclear space and electron dense mitochondria, which are unique morphological features of autosis, were observed. The extract enhanced reactive oxygen species (ROS generation, and the antioxidant N-acetylcystein attenuated cell death. Our study revealed that daily intraperitoneal administration of the extract significantly prolonged survival (P = 0.0069 in a peritoneal dissemination model and suppressed tumor growth in an orthotopic model of pancreatic cancer (P < 0.01 without serious adverse effects. Although [6]-shogaol but not [6]-gingerol showed similar effects, chromatographic analyses suggested the presence of other constituent(s as active substances. Together, these results show that ginger extract has potent anticancer activity against pancreatic cancer cells by inducing ROS-mediated autosis and warrants further investigation in order to develop an efficacious candidate drug.

    Full Text Available Background Diabetes mellitus is a metabolic disorder characterized by high blood glucose level caused due to deficiency of insulin secretion or insulin function. The inhibition of carbohydrate hydrolyzing enzymes such as α-amylase can be an important strategy for decrease postprandial blood glucose level in patients with type II diabetes. Plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. Objectives The aim of the present study is to investigate the effect of the ethanolic extract of Capparis spinosa on pancreatic α-amylase activities to find out the relevance of the plant in controlling blood sugar. Materials and Methods In this experimental study, root and leaves of C. spinosa were tested for α-amylase inhibition. Different concentrations (1.56, 3.12, 6.25, 12.5 and 25 mg/mL of extracts were incubated with enzyme substrate solution and the spectrometric method used for measure enzyme activity. Also acarbose was used as the standard inhibitor. Results Both root and leaves extracts showed inhibition of α-amylase (root = 97.31% and leaves = 98.92%. The root and leaves extracts of C. spinosa exhibited appreciable α-amylase inhibitory activity with an IC50 values 5.93 mg/mL and 3.89 mg/mL respectively, when compared with acarbose (IC50 value 0.038 mg/mL. Conclusions This study supports that root and leaves extracts of C. spinosa exhibit considerable α-amylase inhibitory activities. These results could be useful for developing functional foods by combination of plant-based foods for treatment of diabetes mellitus.

    Diabetes is a major public health concern. In spite of continuous new drug development to treat diabetes, herbal remedies remain a potential adjunct therapy to maintain better glycemic control while also imparting few side-effects. Portulaca oleracea has been traditionally used to manage several diseases due to the anti-oxidant and anti-atherogenic effects it imparts. To better understand the mechanisms associated with potential protective effect of P. oleracea extract against diabetes, alloxan-induced diabetic rats were used in this study. Forty Wistar rats (male, 7-8-wk-old, 140-160 g) were divided into four groups (n = 10/group): Group I (control), Group II (P. oleracea-treated; gavaged with P. oleracea extract daily [at 250 mg/kg] for 4 weeks), Group III (diabetic control; daily IP injection of alloxan [at 75 mg/kg] for 5 days) and Group IV (P. oleracea-pre-treated diabetic; gavaged with P. oleracea extract daily [at 250 mg/kg] for 4 weeks and then daily IP injection of alloxan [at 75 mg/kg] for 5 days). Body weight, food consumption, blood (serum) levels of glucose, C peptide, Hb A1C, insulin, tumor necrosis factor (TNF)-α and interleukin (IL)-6 were determined for all groups. The results indicated that while Hb A1C, serum levels of glucose, TNF-α and IL-6 were all significantly decreased in the P. oleracea-pre-treated diabetic rats, these hosts also had significant increases in C peptide and insulin compared to levels in the counterpart diabetic rats. These results were confirmed by the histopathological assessments which showed marked improvement of the destructive effect on pancreatic islet cells induced by alloxan. P. oleracea extract is a general tissue protective and regeneartive agent, as evidenced by increasing β-cell mass and therefore improved the glucose metabolism. Thus, stimulation of Portulaca oleracea signaling in β- cells may be a novel therapeutic strategy for diabetes prevention.

    Fewer than 6% patients with adenocarcinoma of the pancreas live up to five years after diagnosis. Chemotherapy is currently the standard treatment, however, these tumors often develop drug resistance over time. Agents for increasing the cytotoxic effects of chemotherapy or reducing the cancer cells' chemo-resistance to the drugs are required to improve treatment outcome. Nuclear factor kappa B (NF-kB), a pro-inflammatory transcription factor, reportedly plays a significant role in the resistance of pancreatic cancer cells to apoptosis-based chemotherapy. This study investigated the effect of aqueous Moringa Oleifera leaf extract on cultured human pancreatic cancer cells - Panc-1, p34, and COLO 357, and whether it can potentiates the effect of cisplatin chemotherapy on these cells. The effect of Moringa Oleifera leaf extract alone and in combination with cisplatin on the survival of cultured human pancreatic cancer cells was evaluated by XTT-based colorimetric assay. The distribution of Panc-1 cells in the cell cycle following treatment with Moringa leaf extract was evaluated by flow cytometry, and evaluations of protein levels were via immunoblotting. Data of cell survival following combined treatments were analyzed with Calcusyn software. Moringa Oleifera leaf extract inhibited the growth of all pancreatic cell lines tested. This effect was significant in all cells following exposure to ≥0.75 mg/ml of the extract. Exposure of Panc-1 cells to Moringa leaf extract induced an elevation in the sub-G1 cell population of the cell-cycle, and reduced the expression of p65, p-IkBα and IkBα proteins in crude cell extracts. Lastly, Moringa Oleifera leaf extract synergistically enhanced the cytotoxic effect of cisplatin on Panc-1 cells. Moringa Oleifera leaf extract inhibits the growth of pancreatic cancer cells, the cells NF-κB signaling pathway, and increases the efficacy of chemotherapy in human pancreatic cancer cells.

Hence, this study was designed to evaluate the hypoglycemic and pancreas protective effects of VAC hydroalcoholic extract in D-galactose-induced aging female mice. In the present experimental study, 72 adult female Naval Medical Research Institute (NMRI) mice (weighing 30-35 g) were divided into 6 groups of control, VAC hydroalcoholic extract, D-galactose, D-galactose + VAC hydroalcoholic extract, aged, aged + VAC hydroalcoholic extract. The aged model was prepared by subcutaneous injection of D-galactose for 45 days and, VAC hydroalcoholic extract was gavaged twice a day in the last 7 days. 24 h after the last drug and extract administrations, serum samples and pancreatic tissues were removed to evaluate experimental and histological determinations. Serum glucose level decreased in VAC, D-galactose and, aged-treated groups compared to the control ( P < 0.05). Insulin level increased in VAC and decreased in D-galactose and aged VAC-treated mice compared to the control ( P < 0.05). Homeostasis model assessment-estimated insulin resistance (HOMA-IR) increased in D-galactose, aging, and VAC hydroalcoholic extract groups ( P < 0.05) and, administration of VAC hydroalcoholic extract improved HOMA-IR in D-galactose and aging treated animals. Despite the size of pancreatic islets decreased in aged and D-galactose groups, VAC administration recovered it. Present data showed that VAC hydroalcoholic extract has hypoglycemic and pancreatic protective effects in natural aged and aging model mice.

    Full Text Available Pancreatic cancer is one of the most aggressive cancer entities, with an extremely poor 5-year survival rate. Therefore, novel therapeutic agents with specific modes of action are urgently needed. Marine organisms represent a promising source to identify new pharmacologically active substances. Secondary metabolites derived from marine algae are of particular interest. The present work describes cellular and molecular mechanisms induced by an HPLC-fractionated, hydrophilic extract derived from the Baltic brown seaweed Fucus vesiculosus (Fv1. Treatment with Fv1 resulted in a strong inhibition of viability in various pancreatic cancer cell lines. This extract inhibited the cell cycle of proliferating cells due to the up-regulation of cell cycle inhibitors, shown on the mRNA (microarray data and protein level. As a result, cells were dying in a caspase-independent manner. Experiments with non-dividing cells showed that proliferation is a prerequisite for the effectiveness of Fv1. Importantly, Fv1 showed low cytotoxic activity against non-malignant resting T cells and terminally differentiated cells like erythrocytes. Interestingly, accelerated killing effects were observed in combination with inhibitors of autophagy. Our in vitro data suggest that Fv1 may represent a promising new agent that deserves further development towards clinical application.

    Full Text Available In Korea, soy (Glycine max (L. Merr. leaves are eaten as a seasonal vegetable or pickled in soy sauce. Ethyl acetate extracts of soy leaves (EASL are enriched in pterocarpans and have potent α-glucosidase inhibitory activity. This study investigated the molecular mechanisms underlying the anti-diabetic effect of EASL in C57BL/6J mice with high-fat diet (HFD-induced type 2 diabetes. Mice were randomly divided into normal diet (ND, HFD (60 kcal% fat diet, EASL (HFD with 0.56% (wt/wt EASL, and Pinitol (HFD with 0.15% (wt/wt pinitol groups. Weight gain and abdominal fat accumulation were significantly suppressed by EASL. Levels of plasma glucose, HbA1c, and insulin in the EASL group were significantly lower than those of the HFD group, and the pancreatic islet of the EASL group had greater size than those of the HFD group. EASL group up-regulated neurogenin 3 (Ngn3, paired box 4 (Pax4, and v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (MafA, which are markers of pancreatic cell development, as well as insulin receptor substrate 1 (IRS1, IRS2, and glucose transporter 4 (GLUT4, which are related to insulin sensitivity. Furthermore, EASL suppressed genes involved in hepatic gluconeogenesis and steatosis. These results suggest that EASL improves plasma glucose and insulin levels in mice with HDF-induced type 2 diabetes by regulating β-cell proliferation and insulin sensitivity.

    Full Text Available Objective: To investigate the effect of aqueous extract of Momordica charantia (karela (M. charantia fruits on blood glucose level, pancreatic weight changes and histopathology of pancreatic changes in the streptozotocin (STZ induced diabetic rats. Methods: Thirty-six albino rats were used in the experiment; diabetes mellitus was induced in 30 adult albino rats, using intraperitoneal injection of 55 mg/kg STZ. Six non diabetic rats remained as control (T1 . The diabetic rats were randomly assigned into five equal groups: diabetic control (T2 without any treatment, groups T3, T4, T5 and T6 were treated with aqueous extract of karela fruits daily at a doses of 250, 500 and 750 mg/kg and glibenclamide (5 mg/kg up to 90 d, respectively. At Day 90, all rats were sacrificed, the pancreases of the rats were excised and processed. Results: The results of this study indicate that aqueous extract of M. charantia fruits was able to reduce blood glucose level significantly compared with the diabetic control group (P<0.01. Histopathologically, STZ resulted severe necrotic changes in pancreatic islets. Tissues sections of pancreas in the treated groups showed regeneration of β cells and increased size of pancreatic islets. Conclusions: The present study suggests that oral feeding of M. charantia fruit juice has a significant anti-hyperglycemic effect and may have a role in the regeneration of the β cells in STZ diabetic rats.

    Pancreatic ductal calculi are most often associated with chronic pancreatitis. Radiological features of chronic pancreatitis are readily evident in the presence of these calculi. However, acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. A 59-year-old man presented with a first episode of acute pancreatitis. Contrast enhanced computerized tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) revealed a calculus in the main pancreatic duct in the head of the pancreas causing acute pancreatitis. There were no features suggestive of chronic pancreatitis on CT scanning. The episode acute pancreatitis was managed conservatively. ERCP extraction of the calculus failed as the stone was impacted in the main pancreatic duct resulting in severe acute pancreatitis. Once this resolved, a transduodenal exploration and extraction of the pancreatic ductal calculus was performed successfully. Crystallographic analysis revealed the composition of the calculus was different to that seen in chronic pancreatitis, but more in keeping with a calculus of biliary origin. This could be explained by migration of the biliary calculus via the common channel into the main pancreatic duct. Following the operation the patient made an uneventful recovery and was well at two-year follow up. Acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. Failing endoscopic extraction, transduodenal exploration and extraction is a safe option after resolution of acute pancreatitis.

    Chronic pancreatitis is an ongoing inflammatory process that may over time lead to mal digestion, malabsorption and diabetic syndrome. Identification of risk (etiological) factors based on classifications TIGAR-O or later M-ANNHEIM. These factors (environmental and / or genetic) leads to failure of the stability of the digestive and lysosomal enzymes in the acinar cells, resulting in premature activation of digestive enzymes in the pancreas, and repeated nekroinflamation and fibrosis. The incidence has of the upward trend. Clinically the disease manifests itself in most cases with pain and possibly with nonspecific dyspeptic troubles. Decisive role in the diagnosis playing imaging methods, trans abdominal ultrasonography, computed tomography, magnetic resonance imaging, magnetic cholangiopancretography and foremost endoscopic ultrasonography, which has the highest sensitivity and specificity. Endoscopic retrograde cholangiopancreatography is currently regarded as a method for therapy, not for diagnosis. Less importance is now attached to a functional test. Symptomatic treatment is usually conservative. Abstinence is necessary, easily digestible, but calorie-rich diet with reduced fat. Most patients needed treatment with analgesics. In case of insufficient effect of analgesics is necessary to consider endoscopic therapy or surgery. If the external secretory insufficiency is present are served pancreatic extracts. Diabetic syndrome requires insulin delivery. Generally, chronic pancreatitis is a disease treatable but incurable. Proportion of patients are also dying of pancreatic cancer. (author)

    Chronic pancreatitis is a debilitating condition often associated with severe abdominal pain and exocrine and endocrine dysfunction. The underlying cause is multifactorial and involves complex interaction of environmental, genetic, and/or other risk factors. The pathology is dependent on the underlying pathogenesis of the disease. This review describes the clinical, gross, and microscopic findings of the main subtypes of chronic pancreatitis: alcoholic chronic pancreatitis, obstructive chronic pancreatitis, paraduodenal ("groove") pancreatitis, pancreatic divisum, autoimmune pancreatitis, and genetic factors associated with chronic pancreatitis. As pancreatic ductal adenocarcinoma may be confused with chronic pancreatitis, the main distinguishing features between these 2 diseases are discussed. Copyright © 2016 Elsevier Inc.

    Full Text Available Objective: To evaluate the effect of ethanolic extract of seeds of Linum usitatissimum (EELU in hyperglycemia associated reactive oxygen species (ROS production in peripheral blood mononuclear cells (PBMNCs and pancreatic antioxidant enzymes in alloxan induced diabetic rat. Methods: Diabetes was induced in male Wistar rats by alloxan (120 mg/kg, i.p. . After acute and subacute treatment serum glucose was determined. Oral glucose tolerance test (OGTT was performed in EELU pretreated animals. ROS production in PBMNCs and pancreatic antioxidant enzymes were measured in alloxan induced diabetic rat. Results: Our results showed that, treatment of EELU (200 and 400 mg/kg significantly reduced serum glucose level in acute and subacute study. The antihyperglycaemic effects of EELU showed onset at 4th h (P<0.001 and peak effect at 6th h (P<0.001. The effect was sustained until 24th h with 400 mg/kg. In subacute study, significant antihyperglycaemic effect was observed from 14th day (P<0.001 onwards. In EELU treated rat the body weight was significantly (P<0.001 increased as compared to diabetic group on 21st day onwards. In OGTT, increased glucose utilization was observed. Treatment of EELU 400 mg/kg showed significant reversal in pancreatic GSH (P<0.01 and SOD (P<0.05 indicating antioxidant nature of EELU. Flow cytometric estimation of total ROS production in PBMNCs in diabetic rats was significantly increased (P<0.001, whereas EELU treatment showed significant (P<0.001 decrease in PBMNCs ROS. Conclusions: It is concluded from the investigation that EELU showed antihyperglycaemic effect mediated through inhibition of ROS level in PBMNCs and preservation of endogenous antioxidant enzymes in pancreatic tissue in alloxan induced diabetic rat.

    Introduction Oleandrin, a cardiac glycoside, exerts strong anti-proliferative activity against various human malignancies in in vitro cells. Here, we report the antitumor efficacy of PBI-05204, a supercritical C0₂ extract of Nerium oleander containing oleandrin, in a human pancreatic cancer Panc-1 orthotopic model. Results While all the control mice exhibited tumors by the end of treatment, only 2 of 8 mice (25%) treated for 6 weeks with PBI-05204 (40 mg/kg) showed dissectible tumor at the end of the treatment period. The average tumor weight (222.9 ± 116.9 mg) in mice treated with PBI-05204 (20 mg/kg) was significantly reduced from that in controls (920.0 ± 430.0 mg) (p PBI-05204 (40 mg/kg) treated group showed that the pancreatic tissues of 5/6 mice were normal while the remaining mouse had a tumor the largest diameter of which was less than 2.3 mm. In contrast, while gemcitabine alone did not significantly reduce tumor growth, PBI-05204 markedly enhanced the antitumor efficacy of gemcitabine in this particular model. Ki-67 staining was reduced in pancreatic tumors from mice treated with PBI-05204 (20 mg/kg) compared to that of control, suggesting that PBI-05204 inhibited the proliferation of the Panc-1 tumor cells. PBI-05204 suppressed expression of pAkt, pS6, and p4EPB1 in a concentration-dependent manner in both Panc-1 tumor tissues and human pancreatic cancer cell lines, implying that this novel botanical drug exerts its potent antitumor activity, at least in part, through down-regulation of PI3k/Akt and mTOR pathways.

  6. Protective Effects of the Mushroom Lactarius deterrimus Extract on Systemic Oxidative Stress and Pancreatic Islets in Streptozotocin-Induced Diabetic Rats

    2015-01-01

    Full Text Available The aim of this study was to assess the in vivo effects of the extract of the medicinal mushroom, Lactarius deterrimus, when administered (60 mg/kg, i.p. daily for four weeks to streptozotocin- (STZ- induced diabetic rats. Diabetic rats treated with the L. deterrimus extract displayed several improved biochemical parameters in the circulation: reduced hyperglycemia, lower triglyceride concentration and reduced glycated hemoglobin, glycated serum protein, and advanced glycation end product (AGE levels. This treatment also adjusted the diabetes-induced redox imbalance. Thus, higher activities of the antioxidative enzymes, superoxide dismutase, and catalase in the circulation were accompanied by increased levels of free intracellular thiols and glutathionylated proteins after treatment with the L. deterrimus extract. In addition to a systemic antioxidant effect, the administration of the extract to diabetic rats also had a positive localized effect on pancreatic islets where it decreased AGE formation, and increased the expression of chemokine CXCL12 protein that mediates the restoration of β-cell population through the activation of the serine/threonine-specific Akt protein kinase prosurvival pathway. As a result, the numbers of proliferating cell nuclear antigen- (PCNA- and insulin-positive β-cells were increased. These results show that the ability of the L. deterrimus extract to alleviate oxidative stress and increase β-cell mass represents a therapeutic potential for diabetes management.

We report a case of a 59-year-old Southeast Asian male who presented with fever, weight loss, and obstructive jaundice. CT scan revealed pancreatic mass and enlarged peripancreatic lymph nodes. Endoscopic ultrasound-guided fine needle aspiration confirmed the presence of mycobacterium tuberculosis. Patient also had high immunoglobulin G4 levels suggestive of autoimmune pancreatitis. He was started on antituberculosis medications and steroids. Clinically, he responded to treatment. Follow-up imaging showed findings suggestive of chronic pancreatitis. Discussion. Pancreatic tuberculosis and autoimmune pancreatitis can mimic pancreatic malignancy. Accurate diagnosis is imperative as unnecessary surgical intervention can be avoided. Endoscopic ultrasound-guided fine needle aspiration seems to be the diagnostic test of choice for pancreatic masses. Long-term follow-up is warranted in cases of chronic pancreatitis.

    This study sought to investigate the ameliorative effects of ethanol extract Artocarpus heterophyllus (EAH) in alloxan-induced diabetic rats. The rats were divided into 6 groups, with groups 1 and 2 serving as nondiabetic and diabetic control, respectively; group 3 serving as diabetic rats treated with 5 mg/kg glibenclamide; and groups 4 to 6 were diabetic rats treated with 50, 100, and 150 mg/kg of EAH, respectively. Assays determined were serum insulin, lipid peroxidation, and antioxidant enzyme activities. EAH stem bark reduced fasting blood glucose and lipid peroxidation levels and increased serum insulin levels and activities of antioxidant enzymes. Data obtained demonstrated the ability of EAH stem bark to ameliorate pancreatic β-cell dysfunction in alloxan-induced diabetic rats.

    Pancreatic trauma occurs in approximately 4% of all patients sustaining abdominal injuries. The pancreas has an intimate relationship with the major upper abdominal vessels, and there is significant morbidity and mortality associated with severe pancreatic injury. Immediate resuscitation and investigations are essential to delineate the nature of the injury, and to plan further management. If main pancreatic duct injuries are identified, specialised input from a tertiary hepatopancreaticobiliary (HPB) team is advised. A comprehensive online literature search was performed using PubMed. Relevant articles from international journals were selected. The search terms used were: 'pancreatic trauma', 'pancreatic duct injury', 'radiology AND pancreas injury', 'diagnosis of pancreatic trauma', and 'management AND surgery'. Articles that were not published in English were excluded. All articles used were selected on relevance to this review and read by both authors. Pancreatic trauma is rare and associated with injury to other upper abdominal viscera. Patients present with non-specific abdominal findings and serum amylase is of little use in diagnosis. Computed tomography is effective in diagnosing pancreatic injury but not duct disruption, which is most easily seen on endoscopic retrograde cholangiopancreaticography or operative pancreatography. If pancreatic injury is suspected, inspection of the entire pancreas and duodenum is required to ensure full evaluation at laparotomy. The operative management of pancreatic injury depends on the grade of injury found at laparotomy. The most important prognostic factor is main duct disruption and, if found, reconstructive options should be determined by an experienced HPB surgeon. The diagnosis of pancreatic trauma requires a high index of suspicion and detailed imaging studies. Grading pancreatic injury is important to guide operative management. The most important prognostic factor is pancreatic duct disruption and in these cases

    Full Text Available Background: Autoimmune pancreatitis is a recently described type of pancreatitis of presumed autoimmune etiology. Autoimmune pancreatitis is often misdiagnosed as pancreatic cancer difficult, since their clinical presentations are often similar. The concept of autoimmune pancreatitis was first published in 1961. Since then, autoimmune pancreatitis has often been treated not as an independent clinical entity but rather as a manifestation of systemic disease. The overall prevalence and incidence of the disease have yet to be determined, but three series have reported the prevalence as between 5 and 6 % of all patients with chronic pancreatitis. Patient vary widely in age, but most are older than 50 years. Patients with autoimmune pancreatitis usually complain of the painless jaundice, mild abdominal pain and weight loss. There is no laboratory hallmark of the disease, even if cholestatic profiles of liver dysfunction with only mild elevation of amylase and lipase levels have been reported.Conclusions: Proposed diagnostic criteria contains: (1 radiologic imaging, diffuse enlargement of the pancreas and diffusely irregular narrowing of the main pancreatic duct, (2 laboratory data, elevated levels of serum ã-globulin and/or IgG, specially IgG4, or the presence of autoantibodies and (3 histopathologic examination, fibrotic change with dense lymphoplasmacytic infiltration in the pancreas. For correct diagnosis of autoimmune pancreatitis, criterion 1 must be present with criterion 2 and/or 3. Autoimmune pancreatitis is frequently associated with rheumatoid arthritis, Sjogren’s syndrome, inflammatory bowel disease, tubulointersticial nephritis, primary sclerosing cholangitis and idiopathic retroperitoneal fibrosis. Pancreatic biopsy using an endoscopic ultrasound-guided fine needle aspiration biopsy is the most important diagnostic method today. Treatment with corticosteroids leads to the and resolution of pancreatic inflamation, obstruction and

    Traumatic pancreatitis should be considered as a diagnostic possibility when trauma to the epigastrium is followed by phenomena suggestive of intra-abdominal injury. The presence or absence of hyperamylasemia should be established immediately. Even when traumatic pancreatitis is believed to exist, any suggestion of injury to other viscera should indicate laparotomy. Retroperitoneal rupture of the duodenum may simulate traumatic pancreatitis in all respects, including hyperamylasemia. X-ray studies may be of value in differentiation. Non-complicated traumatic pancreatitis is best treated conservatively. Gunshot and knife wounds of the pancreas should be drained. PMID:13094537

    To summarize recent data on classification systems, cause, risk factors, severity prediction, nutrition, and drug treatment of acute pancreatitis. Comparison of the Revised Atlanta Classification and Determinant Based Classification has shown heterogeneous results. Simvastatin has a protective effect against acute pancreatitis. Young black male, alcohol, smoldering symptoms, and subsequent diagnosis of chronic pancreatitis are risk factors associated with readmissions after acute pancreatitis. A reliable clinical or laboratory marker or a scoring system to predict severity is lacking. The PYTHON trial has shown that oral feeding with on demand nasoenteric tube feeding after 72 h is as good as nasoenteric tube feeding within 24 h in preventing infections in predicted severe acute pancreatitis. Male sex, multiple organ failure, extent of pancreatic necrosis, and heterogeneous collection are factors associated with failure of percutaneous drainage of pancreatic collections. The newly proposed classification systems of acute pancreatitis need to be evaluated more critically. New biomarkers are needed for severity prediction. Further well designed studies are required to assess the type of enteral nutritional formulations for acute pancreatitis. The optimal minimally invasive method or combination to debride the necrotic collections is evolving. There is a great need for a drug to treat the disease early on to prevent morbidity and mortality.

  13. A novel method for RNA extraction from FFPE samples reveals significant differences in biomarker expression between orthotopic and subcutaneous pancreatic cancer patient-derived xenografts.

    Next-generation sequencing (NGS) can identify and validate new biomarkers of cancer onset, progression and therapy resistance. Substantial archives of formalin-fixed, paraffin-embedded (FFPE) cancer samples from patients represent a rich resource for linking molecular signatures to clinical data. However, performing NGS on FFPE samples is limited by poor RNA purification methods. To address this hurdle, we developed an improved methodology for extracting high-quality RNA from FFPE samples. By briefly integrating a newly-designed micro-homogenizing (mH) tool with commercially available FFPE RNA extraction protocols, RNA recovery is increased by approximately 3-fold while maintaining standard A260/A280 ratios and RNA quality index (RQI) values. Furthermore, we demonstrate that the mH-purified FFPE RNAs are longer and of higher integrity. Previous studies have suggested that pancreatic ductal adenocarcinoma (PDAC) gene expression signatures vary significantly under in vitro versus in vivo and in vivo subcutaneous versus orthotopic conditions. By using our improved mH-based method, we were able to preserve established expression patterns of KRas-dependency genes within these three unique microenvironments. Finally, expression analysis of novel biomarkers in KRas mutant PDAC samples revealed that PEAK1 decreases and MST1R increases by over 100-fold in orthotopic versus subcutaneous microenvironments. Interestingly, however, only PEAK1 levels remain elevated in orthotopically grown KRas wild-type PDAC cells. These results demonstrate the critical nature of the orthotopic tumor microenvironment when evaluating the clinical relevance of new biomarkers in cells or patient-derived samples. Furthermore, this new mH-based FFPE RNA extraction method has the potential to enhance and expand future FFPE-RNA-NGS cancer biomarker studies.

    Syzygium cumini (L.) Skeels (Myrtaceae) has been traditionally used to treat a number of illnesses. Ethnopharmacological studies have particularly addressed antidiabetic and metabolic-related effects of extracts prepared from its different parts, especially seed, and pulp-fruit, however. there is a lack of studies on phytochemical profile and biological properties of its leaf. As there is considerable interest in bioactive compounds to treat metabolic syndrome and its clustered risk factors, we sought to characterize the metabolic effects of hydroethanolic extract of S. cumini leaf (HESc) on lean and monosodium L-glutamate (MSG)-induced obese rats. HPLC-MS/MS characterization of the HESc polyphenolic profile, at 254 nm, identified 15 compounds pertaining to hydrolysable tannin and flavanol subclasses. At 60 days of age, both groups were randomly assigned to receive HESc (500 mg/kg) or vehicle for 30 days. At the end of treatment, obese+HESc exhibited significantly lower body weight gain, body mass index, and white adipose tissue mass, compared to obese rats receiving vehicle. Obese rats treated with HESc showed a twofold increase in lipolytic activity in the periepididymal fat pad, as well as, brought triglyceride levels in serum, liver and skeletal muscle back to levels close those found in lean animals. Furthermore, HESc also improved hyperinsulinemia and insulin resistance in obese+HESc rats, which resulted in partial reversal of glucose intolerance, as compared to obese rats. HESc had no effect in lean rats. Assessment of ex vivo glucose-stimulated insulin secretion showed HESc potentiated pancreatic function in islets isolated from both lean and obese rats treated with HESc. In addition, HESc (10–1000 μg/mL) increased glucose stimulated insulin secretion from both isolated rat islets and INS-1E β-cells. These data demonstrate that S. cumini leaf improved peripheral insulin sensitivity via stimulating/modulating β-cell insulin release, which was associated

    Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

    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.

    Early diagnosis of pancreatic trauma has always been challenging because of the lack of correlation between the initial clinical symptomatology, radiologic and laboratory findings, and the severity of the injury. Thanks to the improved performance of spiral CT scanning and magnetic resonance pancreatography, it is now often possible to make an early diagnosis of pancreatic contusion, to localize the site of the injury, and (most importantly) to identify injury to the main pancreatic duct which has major implications for the management of the case. When the trauma victim is unstable, radiologic work-up may be impossible and urgent laparotomy is required. Control of hemorrhage is the primary concern here and a damage control approach with packing may be appropriate; if the pancreatic head has been destroyed, a pancreaticoduodenectomy with delayed reconstruction may be required. If the trauma victim is stable, the treatment strategy will be governed by a variety of parameters--age, clinical condition, associated local anatomic findings (pancreatitis, injury to the duodenum or biliary tract), involvement of the pancreatic duct, and localization of the injury within the gland (to right or left of the mesenteric vessels).

    Despite the recent technological advances in imaging, abdominal ultrasonography continues to be the first diagnostic test indicated in patients with a suspicion of pancreatic disease, due to its safety, accessibility and low cost. It is an essential technique in the study of inflammatory processes, since it not only assesses changes in pancreatic parenchyma, but also gives an indication of the origin (bile or alcoholic). It is also essential in the detection and tracing of possible complications as well as being used as a guide in diagnostic and therapeutic punctures. It is also the first technique used in the study of pancreatic tumors, detecting them with a sensitivity of around 70% and a specificity of 90%.

    Autoimmune pancreatitis (AIP) is a chronic fibroinflammatory disease of the pancreas that belongs to the spectrum of immunoglobulin G-subclass4-related diseases (IgG4-RD) and typically presents with obstructive jaundice. Idiopathic duct-centric pancreatitis (IDCP) is a closely related but distinct disease that mimics AIP radiologically but manifests clinically most commonly as recurrent acute pancreatitis in young individuals with concurrent inflammatory bowel disease. IgG4 levels are often elevated in AIP and normal in IDCP. Histologically, lymphoplasmacytic acinar inflammation and storiform fibrosis are seen in both. In addition, the histologic hallmark of IDCP is the granulocyte epithelial lesion: intraluminal and intraepithelial neutrophils in medium-sized and small ducts with or without granulocytic acinar inflammation often associated with destruction of ductal architecture. Initial treatment of both AIP and IDCP is with oral corticosteroids for duration of 4 weeks followed by a gradual taper. Relapses are common in AIP and relatively uncommon in IDCP, a relatively rare disease for which the natural history is not well understood. For patients with relapsing AIP, treatment with immunomodulators and more recently rituximab has been recommended. Although rare instances of pancreaticobiliary malignancy has been reported in patients with AIP, overall the lifetime risk of developing pancreatic cancer does not appear to be elevated.

Violations of endocrine pancreas arises in 6.5-38 % of patients with acute pancreatitis. However, there is still no clear understanding of the pathogenetic mechanisms of hormonal dysfunction of the pancreas in acute pancreatitis, there is no uniform algorithms for its correction. Aim of the research was to study the endocrine function of pancreas in acute pancreatitis. To define the role of endocrine pancreatic function in the etiology and pathogenesis of the acute pancreatitis. To assess the prospects of the use of pancreatic hormones in the treatment and predicting the outcomes of acute pancreatitis. Materials and methods of the research Survey of publications in specialized periodical medical journals, PubMed sources developed by the National Center for Biotechnology Information. Search in PubMed was carried out in the following databases: MEDLINE, Pre MEDLINE. Results of the research. In a significant proportion of patients who recovered from acute pancreatitis, exocrine and endocrine functional impairments were found. This finding was not detected only in patients after severe acute pancreatitis. Routine evaluation of pancreatic function after acute pancreatitis should be considered. The comparative analysis of the synthetic analogues (somatostatin, calcitonin, leu-enkefalin-dalargin influence on the glucose metabolism of rats in acute pancreatitis of was made. Physiological reaction of beta-cells is preserved in infusion of somatostatin. However, infusion of calcitonin results in the distortion of counterregulatory action of insulin and glucagon.

Despite of all advanced diagnostic methods the disease is in most cases recognised too late when the tumor is not resectable.Conclusions. Only in 20–30% of patients with pancreatic cancer surgical resection is possible, and even in this group 5year survival is very low. In the patients where the tumor is not resectable, sometimes only palliative procedures are indicated and sometimes only simptomatic therapy is possible. The average survival period in this group of patients is 12–20 months. Adjuvant chemo and radiotherapy has not shown much of benefit and the prognosis is still very bad.

    Abstract : Cancer patients experience weight loss for a variety of reasons, commencing with the tumor's metabolism (Warburg effect) and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

  13. Autoimmune pancreatitis can develop into chronic pancreatitis

    Science.gov (United States)

    2014-01-01

    Autoimmune pancreatitis (AIP) has been recognized as a distinct type of pancreatitis that is possibly caused by autoimmune mechanisms. AIP is characterized by high serum IgG4 and IgG4-positive plasma cell infiltration in affected pancreatic tissue. Acute phase AIP responds favorably to corticosteroid therapy and results in the amelioration of clinical findings. However, the long-term prognosis and outcome of AIP remain unclear. We have proposed a working hypothesis that AIP can develop into ordinary chronic pancreatitis resembling alcoholic pancreatitis over a long-term course based on several clinical findings, most notably frequent pancreatic stone formation. In this review article, we describe a series of study results to confirm our hypothesis and clarify that: 1) pancreatic calcification in AIP is closely associated with disease recurrence; 2) advanced stage AIP might have earlier been included in ordinary chronic pancreatitis; 3) approximately 40% of AIP patients experience pancreatic stone formation over a long-term course, for which a primary risk factor is narrowing of both Wirsung’s and Santorini’s ducts; and 4) nearly 20% of AIP patients progress to confirmed chronic pancreatitis according to the revised Japanese Clinical Diagnostic Criteria, with independent risk factors being pancreatic head swelling and non-narrowing of the pancreatic body duct.

    Acute pancreatitis is one of the most frequent gastrointestinal causes of hospital admission in the United States. Chronic pancreatitis, although lower in incidence, significantly reduces patients' quality of life. Pancreatic cancer is associated with a high mortality rate and is one of the top 5 causes of death from cancer. The burden of pancreatic disorders is expected to increase over time. The risk and etiology of pancreatitis differ with age and sex, and all pancreatic disorders affect the black population more than any other race. Gallstones are the most common cause of acute pancreatitis, and early cholecystectomy eliminates the risk of future attacks. Alcohol continues to be the single most important risk factor for chronic pancreatitis. Smoking is an independent risk factor for acute and chronic pancreatitis, and its effects could synergize with those of alcohol. Significant risk factors for pancreatic cancer include smoking and non-O blood groups. Alcohol abstinence and smoking cessation can alter the progression of pancreatitis and reduce recurrence; smoking cessation is the most effective strategy to reduce the risk of pancreatic cancer.

    Type 2 diabetes mellitus, which is usually a result of wrong dietary habits and reduced physical activity, represents 85-95% of all diabetes cases and among other diet related diseases is the major cause of deaths. The disease is characterized mainly by hyperglycemia, which is associated with attenuated insulin sensitivity or beta cells dysfunction caused by multiple stimuli, including oxidative stress and loss of insulin secretion. Since polyphenols possess multiple biological activities and constitute an important part of the human diet, they have recently emerged as critical phytochemicals in type 2 diabetes prevention and treatment. Their hypoglycemic action results from their antioxidative effect involved in recovering of altered antioxidant defenses and restoring insulin secreting machinery in pancreatic cells, or abilities to inhibit the activity of carbohydrates hydrolyzing enzymes (α-amylase and α-glucosidase) or protein tyrosine phosphatase 1B (PTP1B), which is known as the major negative regulator in insulin signaling. This study investigates the total phenolic content (Folin-Ciocalteu and HPLC methods) and antioxidant capacity (ABTS) of 20 polyphenolic extracts obtained from selected edible plants, which were screened in terms of α -amylase, α - glucosidase and protein tyrosine phosphatase 1B inhibitors or protective agents against oxidative stress induced by tertbutylhydroperoxide (t-BOOH) in βTC3 pancreatic beta cells used as a model target for antidiabetes drugs. The study concludes that Chaenomeles japonica, Oenothera paradoxa and Viburnum opulus may be promising natural sources for active compounds with antidiabetic properties.

    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.

    The main principles of treatment of external postoperative pancreatic fistulas are viewed in the article. Pancreatic trauma was the reason of pancreatic fistula in 38.7% of the cases, operations because of acute pancreatitis - in 25.8%, and pancreatic pseudocyst drainage - in 35.5%. 93 patients recovered after the treatment. Complex conservative treatment of EPF allowed to close fistulas in 74.2% of the patients with normal patency of the main pancreatic duct (MPD). The usage of octreotide 600-900 mcg daily for at least 5 days to decrease pancreatic secretion was an important part of the conservative treatment. Endoscopic papillotomy was performed in patients with major duodenal papilla obstruction and interruption of transporting of pancreatic secretion to duodenum. Stent of the main pancreatic duct was indicated in patients with extended pancreatic duct stenosis to normalize transport of pancreatic secretion to duodenum. Surgical formation of anastomosis between distal part of the main pancreatic duct and gastro-intestinal tract was carried out when it was impossible to fulfill endoscopic stenting of pancreatic duct either because of its interruption and diastasis between its ends, or in the cases of unsuccessful conservative treatment of external pancreatic fistula caused by drainage of pseudocyst.

    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.

    The current study was designed to evaluate the various antioxidant potentials and inhibitory effects of phenolic-rich leaf extracts of Bridelia ferruginea (BF) on the in vitro activities of some key enzymes involved in the metabolism of carbohydrates. In this study, BF leaf free and bound phenolic-rich extracts were used. We quantified total phenolic and flavonoid contents, and evaluated several antioxidant activities using assays for ferric reducing antioxidant power, total antioxidant activity (phosphomolybdenum reducing ability), 1,1-diphenyl-2-picrylhydrazyl and thiobarbituric acid reactive species. Also, extracts were tested for their ability to inhibit α-amylase and α-glucosidase activity. The total phenolic and total flavonoid contents in the free phenolic extract of BF were significantly greater than in the bound phenolic extract. Also, all the antioxidant activities considered were significantly greater in the free phenolic extract than in the bound phenolic extract. In the same vein, the free phenolic-rich extract had a significantly higher percentage inhibition against α-glucosidase activity (IC 50  = 28.5 µg/mL) than the bound phenolic extract (IC 50  = 340.0 µg/mL). On the contrary, the free phenolic extract (IC 50  = 210.0 µg/mL) had significantly lower inhibition against α-amylase than the bound phenolic-rich extract (IC 50  = 190.0 µg/mL). The phenolic-rich extracts of BF leaves showed antioxidant potentials and inhibited two key carbohydrate-metabolizing enzymes in vitro. Copyright © 2018 Shanghai Changhai Hospital.

    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 contrast-enhanced 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.

    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

  9. Pancreatic Exocrine Insufficiency in Pancreatic Cancer

    2017-02-01

    Full Text Available Abstract: Cancer patients experience weight loss for a variety of reasons, commencing with the tumor’s metabolism (Warburg effect and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

    There has been no definite examining technique for the early diagnosis of pancreatic diseases, especially small cancers of the pancreas less than 3 cm. Plain abdominal X-rays do not produce reliable roentgenological signs of acute pancreatitis, but the advent of CT has elucidated the condition to some extent. Upper gastrointestinal series are alleged to demonstrate abnormal findings in 80% of cases of pancreatic cancer or cyst. Pancreatic RI scintigraphy expresses the function and anatomy, and the sensitivity with 75 Se is 88%, similar to 87% by US and 80% by CT. Although endoscopic retrograde cholangiopancreatography visualizes extrapancreatic secretory function, as well as the morphology of pancreas, differentiation is not easy in many cases. The greatest indication for US was cysts. The detection rate of pancreatic cancers is similar between plain and contrast CTs, and pancreatic angiography is not specific for pancreatic cancers.

    This study aimed to investigate the impairment of pancreatic endocrine function and the associated risk factors after acute pancreatitis (AP). Fifty-nine patients were subjected to tests of pancreatic function after an attack of pancreatitis. The mean time after the event was 3.5 years. Pancreatic endocrine function was evaluated by fasting blood glucose (FBG), glycosylated hemoglobin, fasting blood insulin, and C-peptide. Homeostasis model assessment was used to evaluate insulin resistance and islet β-cell function. Pancreatic exocrine function was evaluated by fecal elastase 1. Factors that could influence endocrine function were also investigated. Nineteen patients (32%) were found to have elevated FBG, whereas 5 (8%) had abnormal glycosylated hemoglobin levels. The levels of FBG, fasting blood insulin, and C-peptide were higher in patients than in controls (P endocrine insufficiency. Pancreatic exocrine functional impairment was found at the same time. Endocrine functional impairment with insulin resistance was found in patients after AP. Obesity, hyperlipidemia, and diabetes-related symptoms increased the likelihood of developing functional impairment after AP.

    The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

    Pancreatic cancer remains one of the most difficult diseases to cure. Japan pancreas society guidelines for management of pancreatic cancer indicate therapeutic algorithm according to the clinical stage. For locally limited pancreatic cancer (cStage I, II, III in Japanese classification system), surgical resection is recommended, however prognosis is still poor. Major randomized controlled trials of resected pancreatic cancer indicates that adjuvant chemotherapy is superior to observation and gemcitabine is superior to 5-fluorouracil (FU). For locally advanced resectable pancreatic cancer (cStage IVa in Japanese classification system (JCS)), we perform neoadjuvant chemoradiotherapy. Phase I study established a recommended dose of 800 mg gemcitabine and radiation dose of 36 Gy. For locally advanced nonresectable pancreatic cancer (cStage IVa in JCS), chemoradiotherapy followed by chemotherapy is recommended. Although pancreatic cancer is chemotherapy resistant tumor, systemic chemotherapy is recommended for metastatic pancreatic cancer (cStage IVb in JCS). Single-agent gemcitabine is the standard first line agent for the treatment of advanced pancreatic cancer. Meta-analysis of chemotherapy showed possibility of survival benefit of gemcitabine combination chemotherapy over gemcitabine alone. We hope gemcitabine combination chemotherapy or molecular targeted therapy will improve prognosis of pancreatic cancer in the future. (author)

    Full Text Available Pancreatic ductal adenocarcinoma (PDA accounts for 95% of all pancreatic cancers. About 230,000 PDA cases are diagnosed worldwide each year. PDA has the lowest five-year survival rate as compared to others cancers. PDA in Poland is the fifth leading cause of death after lung, stomach, colon and breast cancer. In our paper we have analysed the newest epidemiological research, some of it controversial, to establish the best practical solution for pancreatic cancer prevention in the healthy population as well as treatment for patients already diagnosed with pancreatic cancer. We found that PDA occurs quite frequently but is usually diagnosed too late, at its advanced stage. Screening for PDA is not very well defined except in subgroups of high-risk individuals with genetic disorders or with chronic pancreatitis. We present convincing, probable, and suggestive risk factors associated with pancreatic cancer, many of which are modifiable and should be introduced and implemented in our society.

    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.

    Full Text Available Abstract Hereditary chronic pancreatitis (HCP is a very rare form of early onset chronic pancreatitis. With the exception of the young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. As well, diagnostic criteria and treatment of HCP resemble that of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile duct and duodenal obstruction, and rarely pancreatic cancer. Fortunately, most patients have a mild disease. Mutations in the PRSS1 gene, encoding cationic trypsinogen, play a causative role in chronic pancreatitis. It has been shown that the PRSS1 mutations increase autocatalytic conversion of trypsinogen to active trypsin, and thus probably cause premature, intrapancreatic trypsinogen activation disturbing the intrapancreatic balance of proteases and their inhibitors. Other genes, such as the anionic trypsinogen (PRSS2, the serine protease inhibitor, Kazal type 1 (SPINK1 and the cystic fibrosis transmembrane conductance regulator (CFTR have been found to be associated with chronic pancreatitis (idiopathic and hereditary as well. Genetic testing should only be performed in carefully selected patients by direct DNA sequencing and antenatal diagnosis should not be encouraged. Treatment focuses on enzyme and nutritional supplementation, pain management, pancreatic diabetes, and local organ complications, such as pseudocysts, bile duct or duodenal obstruction. The disease course and prognosis of patients with HCP is unpredictable. Pancreatic cancer risk is elevated. Therefore, HCP patients should strongly avoid environmental risk factors for pancreatic cancer.

    Obstruction of the pancreatic duct can lead to pancreatic fibrosis. We investigated the correlation between the extent of pancreatic fibrosis and the postoperative exocrine and endocrine pancreatic function. Fifty-five patients who were treated for pancreatic and periampullary carcinoma and 19 patients with chronic pancreatitis were evaluated. Exocrine pancreatic function was evaluated by fecal elastase-1 test, while endocrine pancreatic function was assessed by plasma glucose level. The extent of fibrosis, duct dilation and endocrine tissue loss was examined histopathologically. A strong correlation was found between pancreatic fibrosis and elastase-1 level less than 100 microg/g (p pancreatic insufficiency. A strong correlation was found between pancreatic fibrosis and endocrine tissue loss (p pancreatic fibrosis nor endocrine tissue loss were correlated with the development of postoperative diabetes mellitus. Duct dilation alone was neither correlated with exocrine nor with endocrine function loss. The majority of patients develop severe exocrine pancreatic insufficiency after pancreatoduodenectomy. The extent of exocrine pancreatic insufficiency is strongly correlated with preoperative fibrosis. The loss of endocrine tissue does not correlate with postoperative diabetes mellitus. Preoperative dilation of the pancreatic duct per se does not predict exocrine or endocrine pancreatic insufficiency postoperatively. Copyright 2008 S. Karger AG, Basel.

    One of the diseases involving a potential risk of developing chronic pancreatitis is acute pancreatitis. Of the overall number of 231 individuals followed with a diagnosis of chronic pancreatitis, 56 patients were initially treated for acute pancreatitis (24.2 %). Within an interval of 12- 24 months from the first attack of acute pancreatitis, their condition gradually progressed to reached the picture of chronic pancreatitis. The individuals included in the study abstained (from alcohol) following the first attack of acute pancreatitis and no relapse of acute pancreatitis was proven during the period of their monitoring. The etiology of acute pancreatitis identified alcohol as the predominant cause (55.3 %), biliary etiology was proven in 35.7 %. According to the revised Atlanta classification, severe pancreatitis was established in 69.6 % of the patients, the others met the criterion for intermediate form, those with the light form were not included. Significant risk factors present among the patients were smoking, obesity and 18 %, resp. 25.8 % had pancreatogenous diabetes mellitus identified. 88.1 % of the patients with acute pancreatitis were smokers. The majority of individuals with chronic pancreatitis following an attack of acute pancreatitis were of a productive age from 25 to 50 years. It is not only acute alcoholic pancreatitis which evolves into chronic pancreatitis, we have also identified this transition for pancreatitis of biliary etiology.

    Transplantation of insulin-producing tissue offers a physiologic approach to restoration of glycemic control. Whereas transplantation of vascularized pancreatic grafts has recently achieved encouraging results, pancreatic islet cell transplantation holds the promise of low morbidity and reduced requirements for agressive immunosuppression for recipients. Islet cell transplantation was recently demonstrated to induce euglycemia with insulin independence. Imagesp1656-a PMID:21221366

    To differentiate the pancreatic adenocarcinoma from focal pancreatitis on CT and ERCP in cases of focal pancreatic enlargement. We analysed CT findings of 66 patients of pancreatic adenocarcinoma (n = 45) or focal pancreatitis (n = 21) with respect to size, density, calcification, pancreatic or biliary duct dilatation, fat plane obliteration around the vessels, direction of retroperitoneal extension, lymphadenopathy, pseudocyst formation and atrophy of pancreas. ERCP available in 48 patients were analysed in respect to morphologic appearance of CBD and pancreatic duct, and distance between the two ducts. The patients in focal pancreatitis were younger with more common history of alcohol drinking. There was no statistical difference in calcifications of the mass (18% in the adenocarcinoma, 33% in the focal pancreatitis), but a tendency of denser, larger number of calcifications was noted in focal pancreatitis. The finding of fat plane obliteration around the vessels were more common in pancreatic adenocarcinoma, and fascial thickenings were more prominent in focal pancreatitis, although not statistically significant. On ERCP, there were no differential points of CBD, pancreatic duct morphology, but distance between the two ducts at the lesion center was more wider in focal pancreatitis. Differentiating focal pancreatitis from pancreatic adenocarcinoma is difficult. However, we should consider the possibility of focal pancreatitis in cases of patients with young age, having alcoholic history in association with CT findings of large numbers of and dense calcifications, and ERCP findings of prominent separation of two duct at the lesion center

    In people with acute pancreatitis, it is unclear what the role should be for medical treatment as an addition to supportive care such as fluid and electrolyte balance and organ support in people with organ failure. To assess the effects of different pharmacological interventions in people with acute pancreatitis. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2016, Issue 9), MEDLINE, Embase, Science Citation Index Expanded, and trial registers to October 2016 to identify randomised controlled trials (RCTs). We also searched the references of included trials to identify further trials. We considered only RCTs performed in people with acute pancreatitis, irrespective of aetiology, severity, presence of infection, language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and extracted data. We did not perform a network meta-analysis as planned because of the lack of information on potential effect modifiers and differences of type of participants included in the different comparisons, when information was available. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) for the binary outcomes and rate ratios with 95% CIs for count outcomes using a fixed-effect model and random-effects model. We included 84 RCTs with 8234 participants in this review. Six trials (N = 658) did not report any of the outcomes of interest for this review. The remaining 78 trials excluded 210 participants after randomisation. Thus, a total of 7366 participants in 78 trials contributed to one or more outcomes for this review. The treatments assessed in these 78 trials included antibiotics, antioxidants, aprotinin, atropine, calcitonin, cimetidine, EDTA (ethylenediaminetetraacetic acid), gabexate, glucagon, iniprol, lexipafant, NSAIDs (non-steroidal anti-inflammatory drugs), octreotide, oxyphenonium, probiotics, activated protein C, somatostatin, somatostatin plus omeprazole, somatostatin

    Full text: Acute pancreatitis (AP) is an acute inflammatory process of the pancreas with variable involvement of peripancreatic tissues or remote organ systems. Mild AP accounts for 75-80% of the cases and it is characterized by interstitial oedema, absent or minimal organ dysfunction, lack of complications and, usually, uneventful recovery. Severe AP is characterized by pancreatic necrosis, protracted clinical course, high incidence of complications, and high mortality rate. The diagnosis of acute pancreatitis (AP) is generally based on clinical and laboratory findings. The role of imaging is to confirm diagnosis, to assess disease severity - especially by detecting pancreatic necrosis-, to reveal complications of the disease and to guide interventions). Contrast- enhanced multidetector CT is the current 'gold standard' imaging modality in the evaluation of patients with AP. The spectrum of findings seen on CT ranges from a normal appearance to diffuse pancreatic enlargement with poorly defined pancreatic contour and heterogeneous attenuation. Stranding of the fat surrounding the pancreas and fluid collections in the anterior pararenal space, the peritoneal cavity or elsewhere, acquiring the form of the anatomic space where they are developed, may also be disclosed. Lack of pancreatic parenchyma enhancement is indicative of the presence of pancreatic necrosis. CT may reveal biliary tract calculi, calcifications in patients with AP combined with chronic pancreatitis- and air in an inflamed pancreas. Pancreatic abscess is usually seen on CT as a focal low attenuation area with a thick wall that may exhibit enhancement following i.v. contrast media administration. Haemorrhage, pseudoaneurysms, renal and splenic parenchyma complications can also be demonstrated by CT. Balthazar et.al have developed CT classification and severity scores based on the presence of fluid collections and pancreatic necrosis. These scores correlate with the incidence of morbidity and

    Background Acute pancreatitis is a serious medical disorder with no current therapies directed to the molecular pathogenesis of the disorder. Inflammation, inappropriate intracellular activation of digestive enzymes, and parenchymal acinar cell death by necrosis are the critical pathophysiologic processes of acute pancreatitis. Thus, it is necessary to elucidate the key molecular signals that mediate these pathobiologic processes and develop new therapeutic strategies to attenuate the appropriate signaling pathways in order to improve outcomes for this disease. A novel serine/threonine protein kinase D (PKD) family has emerged as key participants in signal transduction, and this family is increasingly being implicated in the regulation of multiple cellular functions and diseases. Methods This review summarizes recent findings of our group and others regarding the signaling pathway and the biological roles of the PKD family in pancreatic acinar cells. In particular, we highlight our studies of the functions of PKD in several key pathobiologic processes associated with acute pancreatitis in experimental models. Results Our findings reveal that PKD signaling is required for NF-κB activation/inflammation, intracellular zymogen activation, and acinar cell necrosis in rodent experimental pancreatitis. Novel small-molecule PKD inhibitors attenuate the severity of pancreatitis in both in vitro and in vivo experimental models. Further, this review emphasizes our latest advances in the therapeutic application of PKD inhibitors to experimental pancreatitis after the initiation of pancreatitis. Conclusions These novel findings suggest that PKD signaling is a necessary modulator in key initiating pathobiologic processes of pancreatitis, and that it constitutes a novel therapeutic target for treatments of this disorder.

    Full Text Available Scrub typhus is a rickettsial infection prevalent in most parts of India. Acute pancreatitis with pseudocyst formation is a rare complication of this condition. This paper reports acute renal failure, pancreatitis and pseudocyst formation in a 48-year-old female with scrub typhus. Ultrasonography of the abdomen revealed a bulky pancreas with fluid seen along the body of the pancreas in the lesser sac. The infection was successfully treated with doxycycline and supportive treatment. Pancreatitis was managed conservatively. This case report highlights the importance of identifying and managing uncommon complications of a common tropical disease for optimum outcome.

    Full Text Available Chronic pancreatitis is a progressive inflammatory disease resulting in permanent structural damage of the pancreas. It is mainly characterized by recurring epigastric pain and pancreatic insufficiency. In addition, progression of the disease might lead to additional complications, such as pseudocyst formation or development of pancreatic cancer. The medical and surgical treatment of chronic pancreatitis has changed significantly in the past decades. With regard to surgical management, pancreatic head resection has been shown to be a mainstay in the treatment of severe chronic pancreatitis because the pancreatic head mass is known to trigger the chronic inflammatory process. Over the years, organ-preserving procedures, such as the duodenum-preserving pancreatic head resection and the pylorus-preserving Whipple, have become the surgical standard and have led to major improvements in pain relief, preservation of pancreatic function, and quality of life of patients.

    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.

    1981-01-01

    It is important to understand which pancreatic function tests are available and how to interpret them when evaluating patients with malabsorption. Available direct tests are the secretin stimulation test, the Lundh test meal, and measurement of serum or fecal enzymes. Indirect tests assess pancreatic exocrine function by measuring the effect of pancreatic secretion on various nutrients. These include triglycerides labeled with carbon 14, cobalamin labeled with cobalt 57 and cobalt 58, and para-aminobenzoic acid bound to a dipeptide. Of all these tests the secretin stimulation test is the most accurate and reliable if done by experienced personnel. However, the indirect tests are simpler to do and appear to be comparable to the secretin test at detecting pancreatic exocrine insufficiency. These indirect tests are becoming clinically available and clinicians should familiarize themselves with the strengths and weaknesses of each

    Full Text Available Pancreatic cancer’s high mortality rate equates closely with its incidence, thereby showing the need for development of biomarkers of its increased risk and a better understanding of its genetics, so that high-risk patients can be better targeted for screening and early potential lifesaving diagnosis. Its phenotypic and genotypic heterogeneity is extensive and requires careful scrutiny of its pattern of cancer associations, such as malignant melanoma associated with pancreatic cancer, in the familial atypical multiple mole melanoma syndrome, due to the CDKN2A germline mutation. This review is designed to depict several of the hereditary pancreatic cancer syndromes with particular attention given to the clinical application of this knowledge into improved control of pancreatic cancer.

    To improve the diagnostic accuracy of pancreatic carcinoma and chronic pancreatitis. The CT findings of 154 cases with pancreatic carcinoma, chronic pancreatitis and mis-diagnosed other pancreatic diseases proven clinically and pathologically were analysed. Slice thickness of 8 mm and slice interval of 8 mm were used and thin-section scan and enhancement study were performed in some cases. The main signs in degassing and differential diagnosis between pancreatic carcinoma and chronic pancreatitis included: (1) focal or diffuse enlargement and density abnormality of pancreas; (2) dilated common bile duct was suddenly obstructed, peripancreatic blood vessels were invaded and cancerous thrombus was revealed, enlargement of abdominal lymph nodes and metastasis in the liver were discovered; (3) calcium deposit in the pancreatic duct area and dilated pancreatic duct which passed through the lesion or not; (4) presence and location of pancreatic cyst and its relationship to pancreatic contour. CT is the imaging modality of choice in the diagnosis of pancreatic carcinoma and chronic pancreatitis at present. The diagnostic accuracy of CT was over 90% in this series

    Pancreatic trauma (PT) is associated with high morbidity and mortality; the therapeutic options remain debated. Retrospective study of PT treated in the University Hospital of Grenoble over a 22-year span. The decision for initial laparotomy depended on hemodynamic status as well as on associated lesions. Main pancreatic duct lesions were always searched for. PT lesions were graded according to the AAST classification. Of a total of 46 PT, 34 were grades II or I. Hemodynamic instability led to immediate laparotomy in 18 patients, for whom treatment was always drainage of the pancreatic bed; morbidity was 30%. Eight patients had grade III injuries, six of whom underwent immediate operation: three underwent splenopancreatectomy without any major complications while the other three who had simple drainage required re-operation for peritonitis, with one death related to pancreatic complications. Four patients had grades IV or V PT: two pancreatoduodenectomies were performed, with no major complication, while one patient underwent duodenal reconstruction with pancreatic drainage, complicated by pancreatic and duodenal fistula requiring a hospital stay of two months. The post-trauma course was complicated for all patients with main pancreatic duct involvement. Our outcomes were similar to those found in the literature. In patients with distal PT and main pancreatic duct involvement, simple drainage is associated with high morbidity and mortality. For proximal PT, the therapeutic options of drainage versus pancreatoduodenectomy must be weighed; pancreatoduodenectomy may be unavoidable when the duodenum is injured as well. Two-stage (resection first, reconstruction later) could be an effective alternative in the emergency setting when there are other associated traumatic lesions. Copyright © 2016.

    2015-09-01

    Biliary obstruction in chronic calcific pancreatitis (CCP) is often caused by inflammatory or fibrotic strictures of the bile duct, carcinoma of head of pancreas or less commonly by compression from pseudocysts. Pancreatic calculi causing ampullary obstruction and leading to obstructive jaundice is extremely rare. The medical records of all patients with CCP or biliary obstruction who underwent endoscopic retrograde cholangiopancreatography (ERCP) over 4 years between 2010-2014 at Kasturba Medical College, Manipal were analyzed. Five patients of CCP with impacted pancreatic calculi at the ampulla demonstrated during ERCP were identified. All 5 presented with biliary obstruction and were incidentally detected to have CCP when evaluated for the same; 3 patients had features of cholangitis. All the patients were managed successfully by endoscopic papillotomy and extraction of pancreatic calculi from the ampulla with resolution of biliary obstruction. Pancreatic calculus causing ampullary obstruction, though very rare, should be considered as a possibility in patients with CCP complicated by biliary obstruction. Endoscopic therapy is affective in the resolution of biliary obstruction in such patients.

    Before the concept of autoimmune pancreatitis (AIP) was established, this form of pancreatitis had been recognized as lymphoplasmacytic sclerosing pancreatitis or non-alcoholic duct destructive chronic pancreatitis based on unique histological features. With the discovery in 2001 that serum IgG4 concentrations are specifically elevated in AIP patients, this emerging entity has been more widely accepted. Classical cases of AIP are now called type 1 as another distinct subtype (type 2 AIP) has been identified. Type 1 AIP, which accounts for 2% of chronic pancreatitis cases, predominantly affects adult males. Patients usually present with obstructive jaundice due to enlargement of the pancreatic head or thickening of the lower bile duct wall. Pancreatic cancer is the leading differential diagnosis for which serological, imaging, and histological examinations need to be considered. Serologically, an elevated level of IgG4 is the most sensitive and specific finding. Imaging features include irregular narrowing of the pancreatic duct, diffuse or focal enlargement of the pancreas, a peri-pancreatic capsule-like rim, and enhancement at the late phase of contrast-enhanced images. Biopsy or surgical specimens show diffuse lymphoplasmacytic infiltration containing many IgG4+ plasma cells, storiform fibrosis, and obliterative phlebitis. A dramatic response to steroid therapy is another characteristic, and serological or radiological effects are normally identified within the first 2 or 3 weeks. Type 1 AIP is estimated as a pancreatic manifestation of systemic IgG4-related disease based on the fact that synchronous or metachronous lesions can develop in multiple organs (e.g. bile duct, salivary/lacrimal glands, retroperitoneum, artery, lung, and kidney) and those lesions are histologically identical irrespective of the organ of origin. Several potential autoantigens have been identified so far. A Th2-dominant immune reaction and the activation of regulatory T-cells are assumed

    Full Text Available Acute pancreatitis is a medical emergency. Alcohol and gallstones are the most common etiologies accounting for 60%-75% cases. Other important causes include postendoscopic retrograde cholangiopancreatography procedure, abdominal trauma, drug toxicity, various infections, autoimmune, ischemia, and hereditary causes. In about 15% of cases the cause remains unknown (idiopathic pancreatitis. Metabolic conditions giving rise to pancreatitis are less common, accounting for 5%-10% cases. The causes include hypertriglyceridemia, hypercalcemia, diabetes mellitus, porphyria, and Wilson′s disease. The episodes of pancreatitis tend to be more severe. In cases of metabolic pancreatitis, over and above the standard routine management of pancreatitis, careful management of the underlying metabolic abnormalities is of paramount importance. If not treated properly, it leads to recurrent life-threatening bouts of acute pancreatitis. We hereby review the pathogenesis and management of various causes of metabolic pancreatitis.

  6. CT of pancreatitis

    One hundred and two cases of acute and chronic pancreatitis were studied by computed tomography. Fluid collection was detected by CT in 45 cases, and the common extrapancreatic sites of involvement included the lesser sac (13 cases), anterior pararenal space (9 cases), transverse mesocolon (7 cases) and posterior pararenal space (5 cases). Ten cases of spontaneous resolution of pancreatic pseudocysts were encountered. Cystojejunostomy was done on 6 patients. A 4-to-6-weeks time interval has been currently accepted as necessary for pseudocyst wall maturation. However, the surgery was not possible in two patients in this series since the cyst wall was too thin. It is considered that the time over 3 months is required for surgical anastomosis of the cyst to the gastrointestinal tract. Pancreatic abscess has become the most common cause of death from pancreatitis. In this series pancreatic abscess occurred in 8 patients. Gas collection in the pancreas was observed in only one patient. In the other patients, pseudocysts had become infected and converted to abscesses. The CT number of 4 infected pseudocysts was less than 15 HU. Thus, it was not possible to distinguish infected from noninfected pseudocysts by CT. The author studied 9 patients with focal inflammatory mass of the pancreas with histologically proved severe fibrosis. All masses were small. Angiography showed occlusion or marked stenosis of the splenic vein in 3 cases. The postcontract CT (after intravenous bolus injection) in 7 cases of focal inflammatory mass demonstrated almost equal enhanced effect of the mass as compared with the adjacent normal pancreatic parenchyma. This finding is considered to be useful in distinguishing inflammatory mass from pancreatic carcinoma. (author)

    Full text: Introduction: Computed Tomography (CT) is the imaging modality of choice for the diagnosis and staging of acute pancreatitis and its complications. Objectives and tasks: The purpose of this presentation is to demonstrate the findings in CT images which are useful for staging acute pancreatitis according to Balthazar, their significance and restrictions. Materials and methods: CT images from patients who were referred to our Department for an abdominal CT scan for the diagnosis or/and staging of acute pancreatitis were retrospectively studied. Results: In acute pancreatitis, CT helps to stage the severity of inflammatory process, to detect pancreatic necrosis and to depict local complications. CT severity index (CTSI), which was proposed by Balthazar et al, combines the grade of pancreatitis with the extent of pancreatic necrosis assigning points to the patients in order to find the severity index which scales from 0-10. More points are given for a higher grade of pancreatitis and for more extensive necrosis. Types of pancreatitis according to CTSI are: interstitial (Balthazar grade A-C), exudative (Balthazar grade D or E), necrotising (Balthazar grade E, CTSI:10) and central gland necrotising. Patients with pancreatitis but no collections or necrosis have an interstitial (mild) pancreatitis. In exudative pancreatitis there is normal enhancement of the entire pancreas associated with extensive peripancreatic collections. Necrotizing (severe) pancreatitis is characterized by protacted clinical course, high incidence of local complications and high mortality rate. Central gland necrosis is a subtype of necrotizing pancreatitis. Conclusions: The combination of CT imaging and clinical and laboratory evaluation allows the early diagnosis of acute pancreatitis. Acute pancreatitis may vary from a mild uneventful disease to a severe life-threatening illness with multisystemic organ failure. Thus, it is crucial to identify patients who are at high risk of severe

    Pancreatic and peripancreatic fluid collections may develop after severe acute pancreatitis. Organized fluid collections such as pancreatic pseudocyst and walled-off pancreatic necrosis (WOPN) that mature over time may require intervention to treat obstructive or constitutional symptoms related to the size and location of the collection as well as possible infection. Endoscopic, open surgical and minimally invasive techniques are described to treat post-inflammatory pancreatic fluid collections. Surgical intervention may be required to treat collections containing necrotic pancreatic parenchyma or in locations not immediately apposed to the stomach or duodenum. Comprising a blend of the surgical approach and the clinical benefits of minimally invasive surgery, the robot-assisted technique of pancreatic cystgastrostomy with pancreatic debridement is described.

    2016-01-01

    Pancreatolithiasis, or pancreatic calculi (PC), is a sequel of chronic pancreatitis (CP) and may occur in the main ducts, side branches or parenchyma. Calculi are the end result, irrespective of the etiology of CP. PC contains an inner nidus surrounded by successive layers of calcium carbonate. These calculi obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Both endoscopic therapy and surgery aim to clear these calculi and decrease ductal hypertension. In small PC, endoscopic retrograde cholangiopancreatography (ERCP) followed by sphincterotomy and extraction is the treatment of choice. Large calculi require fragmentation by extracorporeal shock wave lithotripsy (ESWL) prior to their extraction or spontaneous expulsion. In properly selected cases, ESWL followed by ERCP is the standard of care for the management of large PC. Long-term outcomes following ESWL have demonstrated good pain relief in approximately 60% of patients. However, ESWL has limitations. Per oral pancreatoscopy and intraductal lithotripsy represent techniques in evolution, and in current practice their use is limited to centers with considerable expertise. Surgery should be offered to all patients with extensive PC, associated multiple ductal strictures or following failed endotherapy. PMID:27784844

    Drugs are thought to be a rare cause for acute pancreatitis; however 525 different drugs are listed in the World Health Organization (WHO) database suspected to cause acute pancreatitis as a side effect. Many of them are widely used to treat highly prevalent diseases. The true incidence is not entirely clear since only few systematic population based studies exist. The majority of the available data are derived from case reports or case control studies. Furthermore, the causality for many of these drugs remains elusive and for only 31 of these 525 dugs a definite causality was established. Definite proof for causality is defined by the WHO classification if symptoms reoccur upon rechallenge.In the actual algorithm the diagnosis is confirmed if no other cause of acute pancreatitis can be detected, and the patient is taking one of the suspected drugs.

    2014-01-01

    Pancreatic transplantation, performed alone or in conjunction with kidney transplantation, is an effective treatment for advanced type I diabetes mellitus and select patients with type II diabetes mellitus. Following advancements in surgical technique, postoperative management, and immunosuppression, pancreatic transplantation has significantly improved the length and quality of life for patients suffering from pancreatic dysfunction. While computed tomography (CT) and magnetic resonance imaging (MRI) have more limited utility, ultrasound is the preferred initial imaging modality to evaluate the transplanted pancreas; gray-scale assesses the parenchyma and fluid collections, while Doppler interrogation assesses vascular flow and viability. Ultrasound is also useful to guide percutaneous interventions for the transplanted pancreas. With knowledge of the surgical anatomy and common complications, the abdominal radiologist plays a central role in the perioperative and postoperative evaluation of the transplanted pancreas

    To investigate hypoglycaemic, hypolipidaemic and pancreatic beta cell regeneration activities of Momordica charantia L fruits (MC). Alloxan-induced diabetic rabbits were treated with methanolic and ethanolic MC extract. Effects of plant extracts and the drug glibenclamide on serum glucose, lipid profile and pancreatic beta cell were determined after two weeks of treatment. Serum glucose and lipid profiles were assayed by kit methods. Pancreatic tissue histopathology was performed to study pancreatic beta cell regeneration. Momordica charantia extracts produced significant hypoglycaemic effects (p Momordica charantia supplementations were unable to normalize glucose and lipid profiles. Glibenclamide, a standard drug, not only lowered hyperglycaemia and hyperlipidaemia but also restored the normal levels. Regeneration of pancreatic beta cells by MC extracts was minimal, with fractional improvement produced by glibenclamide. The most significant finding of the present study was a 28% reduction in hyperglycaemia by MC ethanol extracts. To determine reliable antidiabetic potentials of MC, identification of the relevant antidiabetic components and underlying mechanisms is warranted. PMID:25429471

    Full Text Available Lymphangioma of the pancreas is a rare benign tumor of lymphatic origin. Retroperitoneal lymphangiomas account for 1% of all lymphangiomas. Herein, we report a case of cystic pancreatic lymphangioma diagnosed in 34 year-old female patient who was hospitalized for a slight pain in the epigastrium and vomiting. Radiological imaging revealed a large multiloculated cystic abdominal mass with enhancing septations involving the upper retroperitoneum. During the laparoscopic surgery, a well circumscribed polycystic tumor was completely excised preserving the pancreatic duct. The patient made a complete recovery and is disease-free 12 months postoperatively.

In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

    Pancreatic heterotopias (HP) are rare. They can occur at any age with a slight male predominance. These lesions are usually asymptomatic and they are often found incidentally during upper or lower GI endoscopy or during the anatomo-pathological examination of an organ which was resected for other reasons; they can be isolated or associated with a digestive pathology. We report, through observation, the association of HP with serous cystadenoma of the pancreas discovered during examinations to identify the etiology of isolated abdominal pain. The aim of this study is to analyse clinical and histological features of this rare pathology.

    Heterotopic pancreatic parenchyma recapitulates the normal pancreas in extrapancreatic locations and, on rare occasions, can even give rise to pancreatic adenocarcinoma. The genetic signatures of pancreatic adenocarcinoma and its precursor lesions are well characterized. We explored the genetic alterations in precursor lesions (intraductal papillary mucinous neoplasms [IPMN], pancreatic intraepithelial neoplasia [PanIN]) in patients with pancreatic heterotopias but without concomitant pancreatic ductal adenocarcinomas. This allowed us to determine whether the stereotypical dysplasia--infiltrating carcinoma sequence also occurs in these extrapancreatic foci. Seven cases of heterotopic pancreas with ductal precursor lesions were identified. These included 2 IPMNs with focal high-grade dysplasia and 5 PanINs with low- to moderate-grade dysplasia (PanIN grades 1-2). Neoplastic epithelium was microdissected and genomic DNA was extracted. Sequencing of commonly mutated hotspots (KRAS, TP53, CDKN2A, SMAD4, BRAF, and GNAS) in pancreatic ductal adenocarcinoma and its precursor lesions was performed. Both IPMNs were found to have KRAS codon 12 mutations. The identification of KRAS mutations suggests a genetic pathway shared with IPMN of the pancreas. No mutations were identified in our heterotopic PanINs. One of the possible mechanisms for the development of dysplasia in these lesions is field effect. At the time of these resections, there was no clinical or pathologic evidence of a prior or concomitant pancreatic lesion. However, a clinically undetectable lesion is theoretically possible. Therefore, although a field effect cannot be excluded, there was no evidence for it in this study. Copyright © 2015 Elsevier Inc. All rights reserved.

    Chronic pancreatitis has long been thought to be mainly associated with immoderate alcohol consumption. The observation that only ∼10% of heavy drinkers develop chronic pancreatitis not only suggests that other environmental factors, such as tobacco smoke, are potent additional risk factors, but also that the genetic component of pancreatitis is more common than previously presumed. Either disease-causing or protective traits have been indentified for mutations in different trypsinogen genes, the gene for the trypsin inhibitor SPINK1, chymotrypsinogen C, and the cystic fibrosis transmembane conductance regulator (CFTR). Other factors that have been proposed to contribute to pancreatitis are obesity, diets high in animal protein and fat, as well as antioxidant deficiencies. For the development of pancreatic cancer, preexisting chronic pancreatitis, more prominently hereditary pancreatitis, is a risk factor. The data on environmental risk factors for pancreatic cancer are, with the notable exception of tobacco smoke, either sparse, unconfirmed or controversial. Obesity appears to increase the risk of pancreatic cancer in the West but not in Japan. Diets high in processed or red meat, diets low in fruits and vegetables, phytochemicals such as lycopene and flavonols, have been proposed and refuted as risk or protective factors in different trials. The best established and single most important risk factor for cancer as well as pancreatitis and the one to clearly avoid is tobacco smoke. Copyright © 2011 S. Karger AG, Basel.

    Full text: Our purpose was to evaluate the gallbladder (GB) emptying in pts with chronic pancreatitis and to determine whether or not the use of pancreatic extract has an impact in improving that function. The GB emptying was evaluated in 11 patients (pts) with mild to moderate chronic pancreatitis, and in 10 normal volunteers. Pts and controls who presented any kind of condition that could interfere with the gastric or gallbladder emptying were excluded. The GB ejection fraction was calculated at 30, 45, and 60 minutes after a standardized fatty meal ingestion. In the pts group, this evaluation was obtained in two different periods of time, without and with the addition of pancreatic extract. The gastric emptying was previously determined in all patients and controls with Technetium-99m-sulfur colloid mixed in the same fatty meal used for the hepatobiliary scans. The results disclosed that the GB ejection fraction at 60 minutes was significantly lower in patients compared to controls ( 0,05). The gastric emptying was similar between the two groups (p>0,05). In conclusion, mild to moderate chronic pancreatitis is associated with GB function impairment. Our results suggest that the delay in GB emptying does not depend exclusively on the alteration in the intestinal phase of the GB stimulation, but may be a result of multiple other factors

    Patients with predicted severe necrotizing pancreatitis as diagnosed by C-reactive protein (>150 mg/L) and/or contrast-enhanced computed tomography should be managed in the intensive care unit. Prophylactic broad-spectrum antibiotics reduce infection rates and survival in severe necrotizing pancreatitis. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy is a causative therapy for gallstone pancreatitis with impacted stones, biliary sepsis, or obstructive jaundice. Fine needle aspiration for bacteriology should be performed to differentiate between sterile and infected pancreatic necrosis in patients with sepsis syndrome. Infected pancreatic necrosis in patients with clinical signs and symptoms of sepsis is an indication for surgery. Patients with sterile pancreatic necrosis should be managed conservatively. Surgery in patients with sterile necrosis may be indicated in cases of persistent necrotizing pancreatitis and in the rare cases of "fulminant acute pancreatitis." Early surgery, within 14 days after onset of the disease, is not recommended in patients with necrotizing pancreatitis. The surgical approach should be organ-preserving (debridement/necrosectomy) and combined with a postoperative management concept that maximizes postoperative evacuation of retroperitoneal debris and exudate. Minimally invasive surgical procedures have to be regarded as an experimental approach and should be restricted to controlled trials. Cholecystectomy should be performed to avoid recurrence of gallstone-associated acute pancreatitis.

    2017-03-01

    Full Text Available Eosinophilic pancreatitis is a rare form of recurrent acute pancreatitis that demonstrates distinct histologic features, including diffuse, periductal, acinar, and septal inflammatory infiltrates comprised of a pure or predominant population of eosinophils, eosinophilic phlebitis and arteritis, and localized eosinophilic infiltrates with pseudocyst formation. It is associated with elevated serum immunoglobulin E levels, an elevated eosinophil count with systemic manifestations, and eosinophilic infiltrates in other organs of the gastrointestinal tract. We present a case of eosinophilic pancreatitis in a 44-year-old man who was diagnosed after pancreatic resection for recurrent bouts of acute pancreatitis. While the gross and histologic evaluations matched other reported cases of eosinophilic pancreatitis, our patient had only minimal peripheral eosinophilia, no reported history of symptoms related to elevated eosinophilia or immunoglobulin E, and only mild eosinophilic infiltrates in his gallbladder.

    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

    Background & Aims Acute pancreatitis increases morbidity and mortality from organ necrosis by mechanisms that are incompletely understood. Dendritic cells (DCs) can promote or suppress inflammation, depending on their subtype and context. We investigated the roles of DC in development of acute pancreatitis. Methods Acute pancreatitis was induced in CD11c.DTR mice using caerulein or L-arginine; DCs were depleted by administration of diphtheria toxin. Survival was analyzed using Kaplan-Meier analysis. Results Numbers of MHC II+CD11c+DC increased 100-fold in pancreas of mice with acute pancreatitis, to account for nearly 15% of intra-pancreatic leukocytes. Intra-pancreatic DC acquired an immune phenotype in mice with acute pancreatitis; they expressed higher levels of MHC II and CD86 and increased production of interleukin-6, membrane cofactor protein (MCP)-1, and tumor necrosis factor (TNF)-α. However, rather than inducing an organ-destructive inflammatory process, DC were required for pancreatic viability; the exocrine pancreas died in mice that were depleted of DC and challenged with caerulein or L-arginine. All mice with pancreatitis that were depleted of DC died from acinar cell death within 4 days. Depletion of DC from mice with pancreatitis resulted in neutrophil infiltration and increased levels of systemic markers of inflammation. However, the organ necrosis associated with depletion of DC did not require infiltrating neutrophils, activation of NF-κB, or signaling by mitogen-activated protein kinase or TNF-α. Conclusions DC are required for pancreatic viability in mice with acute pancreatitis and might protect organs against cell stress. PMID:21801698

    Autoimmune pancreatitis (AIP) is a newly developed concept for a peculiar type of pancreatitis, and at present is recognized as a pancreatic lesion reflecting IgG4-related systemic disease. It is of utmost importance to differentiate AIP from pancreatic cancer to avoid unnecessary surgery. The current management strategies for AIP, including its clinical features, diagnostic criteria, clinical subtypes, steroid therapy and prognosis are discussed, based on our 66 AIP cases and papers searched in PubMed from 1992 to March 2011, using the term 'autoimmune pancreatitis'. A new clinicopathological entity, an 'IgG4-related sclerosing disease' is also mentioned. AIP should be considered in the differential diagnosis in elderly male patients presented with obstructive jaundice and pancreatic mass. Steroids are a standard therapy for AIP, but their regimen including maintenance therapy should be evaluated in prospective trials.

    2017-06-01

    Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay. Moreover, new technologies, such as intraoperative fluorescence guidance and augmented reality will define additional indications for robot-assisted pancreatic surgery.

    Pancreatic cancer is one of the most deadly solid tumors, with an overall 5-year survival rate of less than 5%. Due to a non-specific clinical presentation, it is often diagnosed at an advanced stage and is rarely amenable for curative treatment. Therefore early diagnosis and appropriate staging are still essential to define the best care and to improve patient survival. Several imaging modalities are currently available for the evaluation of pancreatic cancer. This review focuses on different techniques and discusses the diagnostic management of patients with pancreatic cancer.

    Full Text Available Pancreatic cancer is the fourth leading cause of cancer death with a median survival of 6 months and a dismal 5-year survival rate of 3-5%. The development and progression of pancreatic cancer are caused by the activation of oncogenes, the inactivation of tumor suppressor genes and the deregulation of many signalling pathways. Therefore, the strategies targeting these molecules as well as their downstream signalling could be promising for the prevention and treatment of pancreatic cancer. However, although targeted therapies for pancreatic cancer have yielded encouraging results in vitro and in animal models, these findings have not been translated into improved outcomes in clinical trials. This failure is due to an incomplete understanding of the biology of pancreatic cancer and to the selection of poorly efficient or imperfectly targeted agents. In this review, we will critically present the current knowledge regarding the molecular, biochemical, clinical and therapeutic aspects of pancreatic cancer.

    Pancreatic cancer is the fourth leading cause of cancer death with a median survival of 6 months and a dismal 5-year survival rate of 3–5%. The development and progression of pancreatic cancer are caused by the activation of oncogenes, the inactivation of tumor suppressor genes, and the deregulation of many signaling pathways. Therefore, the strategies targeting these molecules as well as their downstream signaling could be promising for the prevention and treatment of pancreatic cancer. However, although targeted therapies for pancreatic cancer have yielded encouraging results in vitro and in animal models, these findings have not been translated into improved outcomes in clinical trials. This failure is due to an incomplete understanding of the biology of pancreatic cancer and to the selection of poorly efficient or imperfectly targeted agents. In this review, we will critically present the current knowledge regarding the molecular, biochemical, clinical, and therapeutic aspects of pancreatic cancer.

    CT was found to be a reliable, often specific, and noninvasive method for detecting pancreatic diseases. In a study of pancreatic lesions, 37 cases having satisfactory operative and histological proofs were analyzed by CT at PMC from Jan. 1986 to Oct. 1987. The results were as following: 1. Male:female is 26:11. 2. The incidence of pancreatic disease were as follows: 1) Pancreatic cancer:21 cases (56%) a.Head:12 cases b.Body:4 cases c.Tail:1 case d.Body and tail:1 case e.Uncinate process:2 cases f.Entire pancreas: 1 case 2) Acute pancreatitis: 6 cases (16%) 3) Chronic pancreatitis:5 cases (14%) 3. The characteristic CT findings: 1) 100% of pancreatic head cancer showed focal mass or alteration of pancreatic head contour and biliary tree dilatation, and 33% (7/12) fat line obliteration. 2) All of other pancreatic cancer except head appeared as focal mass or contour alteration and fat line obliteration. 3) Total 6 cases of acute pancreatitis showed that 5 cases diffuse enlargement of pancreas, 3 fluid collection (2 cases:left anterior pararenal and posterior pararenal space and lesser sac, 1 case:only pancreas body) and 1 case abscess formation. 4) Total 5 cases of chronic pancreatitis revealed diffuse enlargement 2 cases and atrophy 1 case, pancreatic ductal dilatation 3 cases, calcification 2 cases, and biliary tree dilatation with CBD tapering appearance 1 case. 5) All cases of pseudocysts were well marginated cystic lesions that located at head in 3 cases and tail 3 cases, and 4 cases were well defined pure cystic masses but 1 case was well capsulated cyst with multiple internal septation

    Pancreatic scintiphotography was performed in 108 cases of patients with diabetes mellitus. Scintiphotos were taken at 30 min. after intravenous injection of approximately 200μCi of 75 Se-selenomethionine using a Toshiba gamma camera. The relationship between the degree of pancreatic uptake of 75 Se-selenomethionine and the types and duration of diabetes, vascular complications and the average range of fasting blood sugar levels were studied. In some cases, pancreatic scintiphotos were taken at 10, 30 and 50 min. after injection of 75 Se-selenomethionine, and the degrees of the pancreatic uptake were compared on each time course. Only two out of 24 cases of insulin-dependent diabetics showed normal pancreatic scintiphotos. On the other hand, two out of 47 cases of mild diabetics treated with diet alone showed no uptake in pancreatic scintiphotos. There was a tendency toward abnormal pancreatic scintiphotos in chronic diabetics. Especially, of the 15 cases who had diabetes for more than eleven years, only one case showed a normal pancreatic scintiphoto. Abnormal pancreatic scintiphotos were found more frequently in the group of poorly controlled diabetics than in the group of well controlled diabetics. In cases showing normal pancreatic scintiphotos, diabetic retinopathy was less frequently found. Out of 36 cases which had sequential pancreatic scintiphotos, hypertension and/or arteriosclerosis were found more frequently in the 20 cases which showed a delay in reaching a plateau of the activity. However, the uptake in sequential pancreatic scintiphotos showed no definite correlation between diabetic retinopathy and other diabetic conditions. (auth.)

    Food allergy, a commonly increasing problem worldwide, defined as an adverse immune response to food. A variety of immune-related effector cells such as mast cells, eosinophils, neutrophils, and T cells are involved in food-related allergic responses categorized as IgE mediated, non-IgE mediated, and mixed (IgE and non-IgE) depending upon underlying immunological mechanisms. The dietary antigens mainly target the gastrointestinal tract including pancreas that gets inflamed due to food allergy and leads acute pancreatitis. Reports indicate several food proteins induce pancreatitis; however, detailed underlying mechanism of food-induced pancreatitis is unexplored. The aim of the review is to understand and update the current scenario of food-induced pancreatitis. A comprehensive literature search of relevant research articles has been performed through PubMed, and articles were chosen based on their relevance to food allergen-mediated pancreatitis. Several cases in the literature indicate that acute pancreatitis has been provoked after the consumption of mustard, milk, egg, banana, fish, and kiwi fruits. Food-induced pancreatitis is an ignored and unexplored area of research. The review highlights the significance of food in the development of pancreatitis and draws the attention of physicians and scientists to consider food allergies as a possible cause for initiation of pancreatitis pathogenesis.

    Chronic pancreatitis is a progressive inflammatory disease giving rise to several complications that need to be treated accordingly. Because pancreatic surgery has significant morbidity and mortality, less invasive therapy seems to be an attractive option. This paper reviews current state-of-the-art strategies to treat chronic pancreatitis without surgery and the current guidelines for the medical therapy of chronic pancreatitis. Endoscopic therapy of complications of chronic pancreatitis such as pain, main pancreatic duct strictures and stones as well as pseudocysts is technically feasible and safe. The long-term outcome, however, is inferior to definitive surgical procedures such as resection or drainage. On the other hand, the medical therapy of pancreatic endocrine and exocrine insufficiency is well established and evidence based. Endoscopic therapy may be an option to bridge for surgery and in children/young adolescents and those unfit for surgery. Pain in chronic pancreatitis as well as treatment of pancreatic exocrine insufficiency follows established guidelines. Copyright © 2013 S. Karger AG, Basel.

    Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5 to 8%. There is no clear pathophysiological basis, but elevated parathyroid hormone and high serum calcium levels could be responsible for calcium deposit in the pancreatic ducts and activation of pancreatic enzymes, which may be the main risk factor for developing acute pancreatitis. The aim of this report is to describe four cases. Four cases are reported of severe pancreatitis associated with hypercalcaemia secondary to primary hyperparathyroidism; three of them with complications (two pseudocysts and one pancreatic necrosis). Cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, studies showed the parathyroid adenoma. Surgical resection was the definitive treatment in all four cases. None of the patients had recurrent acute pancreatitis events during follow-up. Acute pancreatitis secondary to hypercalcaemia of primary hyperparathyroidism is rare; however, when it occurs it is associated with severe pancreatitis. It is suspected in patients with elevated serum calcium and high parathyroid hormone levels. Imaging techniques such as cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, should be performed, to confirm clinical suspicion. Surgical resection is the definitive treatment with excellent results. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    Impaired glucose tolerance or frank diabetes mellitus is known to occur more frequently in patients with pancreatic cancer than in the general population. At the time of the diagnosis of pancreatic cancer, more than 70% of patients taking the glucose tolerance test show diabetes or impaired glucose tolerance (1). Relationship among diabetes mellitus and pancreatic cancer is vague but sure, although neither the nature nor the sequence of the possible cause – effect relationship has been established. The reason for the high frequency of glucose intolerance in patients with pancreatic cancer remains controversial. (author)

    Pancreatic cancer is the fourth comment cause of cancer-related death in men. Most patients with pancreatic cancer are diagnosed at advanced, non-resectable stage. Late detection, early metastases, difficult surgical approached, cancer resistant to systemic chemo and radiotherapy - all contribute to its in faust prognosis. Only about 5 % of patients will live 5 years after diagnosis. Gemcitabine - based combination treatments is the standard for advanced pancreatic cancer. The combination of fluorouracil, folinic acid, irinotecan and oxaliplatin led to median survival of 11 months. No standard second-line treatment exists for pancreatic cancer. (author)

    The purpose of this study was to evaluate the cationic trypsinogen gene in miniature schnauzers for possible mutations. Genetic mutations have been linked with hereditary pancreatitis in humans. Four miniature schnauzers were selected on the basis of a clinical history of pancreatitis. One healthy miniature schnauzer and 1 healthy mixed breed canine were enrolled as controls. DNA was extracted from these canines using a commercial kit. Primers were designed to amplify the entire canine cationic trypsinogen cDNA sequence. A polymerase chain reaction (PCR) was performed and products were purified and sequenced. All sequences were then compared. The healthy control canine, a healthy miniature schnauzer, and the 4 miniature schnauzers with pancreatitis showed identical sequences of the cationic trypsinogen gene to the published sequence. We conclude that, in contrast to humans with hereditary pancreatitis, mutations of the cationic trypsinogen gene do not play a major role in the genesis of pancreatitis in the miniature schnauzer.

Because of its relatively small volume, the complete pancreas can be scanned in a single breathhold. For pancreatic examinations, 1 continuous, 1- second scans with a table feed of 10 mm/sec were obtained on a Siemens SOMATOM Plus. Contrast material (50 mL) was power injected immediately before the start of measurements. CT images were reconstructed from the volume data set at 2-mm intervals. Fifty-six patients with pancreatitis, carcinoma or metastases of the pancreas; endocrine-active tumors; or Echinococcus were examined with both conventional and spiral CT

    Ductal adenocarcinoma is the most frequent solid tumor of the pancreas. This tumor has distinct features including early obstruction of the pancreatic duct, diminished enhancement after administration of contrast material due to desmoplastic growth, high propensity to infiltrate adjacent structures and to metastasize into the liver and the peritoneum. Hormone active endocrine tumors cause specific clinical symptoms. Imaging is aimed at localization of these hypervascular tumors. Non hormone active tumors are most frequently malignant and demonstrate very varying features. Cystic pancreatic tumors are increasingly detected by means of cross sectional imaging. Exact classification can be achieved with knowledge of the macropathology and considering clinical presentation as well as age and gender of the patients. (orig.)

    Pancreatic cancer sometimes occurs during the course of chronic pancreatitis. This study aimed to identify risk factors for developing pancreatic cancer associated with chronic pancreatitis. The incidence of pancreatic cancer developing in 218 patients with chronic pancreatitis and clinical features of the chronic pancreatitis patients who developed pancreatic cancer were studied. Nine patients developed pancreatic cancer. Average period from the diagnosis of chronic pancreatitis to the diagnosis of pancreatic cancer was 9.6 years. All pancreatic cancers were diagnosed at an advanced stage. Only 2 patients had been followed-up periodically. There were no significant differences between chronic pancreatitis patients who developed pancreatic cancer and those who did not in male/female ratio (3.5 vs. 8), average age on diagnosis (65.0 vs. 56.5), alcoholic/non-alcoholic chronic pancreatitis (1.6 vs. 2.6), smoking habits (62.5% vs. 70.7%), diabetes mellitus (77.8% vs. 54.4%), and continued alcohol drinking (37.5% vs. 53.1%). Over the period examined, 4% of chronic pancreatitis patients developed pancreatic cancer. Sex ratio, onset age, etiology, smoking habits, diabetes mellitus, and continued alcohol drinking were not significant risk factors for developing pancreatic cancer in chronic pancreatitis patients. Periodic follow-up due to the possibility of pancreatic cancer is necessary in chronic pancreatitis patients.

    Malabsorption due to severe pancreatic exocrine insufficiency is one of the most important late features of chronic pancreatitis. Generally, steatorrhea is more severe and occurs several years prior to malabsorption of other nutrients because synthesis and secretion of lipase are impaired more rapidly, its intraluminal survival is shorter, and the lack of pancreatic lipase activity is not compensated for by nonpancreatic mechanisms. Patients suffer not only from nutritional deficiencies but also from increased nutrient delivery to distal intestinal sites, causing symptoms by profound alteration of upper gastrointestinal secretory and motor functions. Adequate nutrient absorption requires delivery of sufficient enzymatic activity into the duodenal lumen simultaneously with meal nutrients. The following recommendations are based on modern therapeutic concepts: 25,000 to 40,000 units of lipase per meal using pH-sensitive pancreatin microspheres, with dosage increases, compliance checks, and differential diagnosis in case of treatment failure. Still, in most patients, lipid digestion cannot be completely normalized by current standard therapy, and future developments are needed to optimize treatment.

    Fragments of the nafenopin-induced pancreatic acinar cell carcinoma of rat have been examined in vitro for patterns of intracellular protein transport and carbamylcholine-induced protein discharge. Continuous incubation of the fragments with [3H]-leucine for 60 minutes resulted in labeling of rough endoplasmic reticulum, Golgi cisternae, and mature zymogen granules, revealed by electron microscope autoradiography. This result indicates transport of newly synthesized protein from the rough endoplasmic reticulum to mature zymogen granules in approximately 60 minutes. The secretagogue carbamylcholine induced the discharge of radioactive protein by carcinoma fragments pulse-chase labeled with [3H]-leucine. A maximal effective carbamylcholine concentration of 10(-5) M was determined. The acinar carcinoma resembles normal exocrine pancreas in the observed rate of intracellular protein transport and effective secretagogue concentration. However, the acinar carcinoma fragments demonstrated an apparent low rate of carbamylcholine-induced radioactive protein discharge as compared with normal pancreatic lobules or acinar cells. It is suggested that the apparent low rate of radioactive protein discharge reflects functional immaturity of the acinar carcinoma. Possible relationships of functional differentiation to the heterogeneous cytodifferentiation of the pancreatic acinar carcinoma are discussed

    A correlation of several clinical parameters and pancreatitis morphological alterations observed in chronic alcoholics with and without pancreatic is presented. Three groups of patients were studied: asymptomatic chronic alcoholics (24); non-alcoholic controls (10); and cases with advanced chronic pancreatitis (6). Clinical, biochemical and functional studies were performed. Morphological studies were made on surgical biopsy specimens in light and electron microscopy. The results of this study showed: 1) fat accumulates within pancreatic acinar cells in alcoholics drinking more than 80 g of ethanol per day; 2) ultrastructural changes found in acinar cells of the alcoholics are similar to those described for liver cells; 3) the alterations found in alcoholics without pancreatitis are also observed in those with advanced chronic pancreatitis. An attempt to correlate the sequential changes in the histopathology of alcoholic pancreatic disease with the clinical picture and secretory patterns was made. According to these observations, admitting the ultrastructural similarities between the liver and the pancreas and the recently demonstrated abnormalities of lipid metabolism in pancreatic cells in experimental animal research, the authors postulate a toxic-metabolic mechanism as a likely hypothesis for the pathogenesis of chronic alcoholic inflammation of the pancreas.

    Pancreatic cancer is an aggressive malignancy with a poor prognosis. The disease and its treatment can cause significant nutritional impairments that often adversely impact patient quality of life (QOL). The pancreas has both exocrine and endocrine functions and, in the setting of cancer, both systems may be affected. Pancreatic exocrine insufficiency (PEI) manifests as weight loss and steatorrhea, while endocrine insufficiency may result in diabetes mellitus. Surgical resection, a central component of pancreatic cancer treatment, may induce or exacerbate these dysfunctions. Nutritional and metabolic dysfunctions in patients with pancreatic cancer lack characterization, and few guidelines exist for nutritional support in patients after surgical resection. We reviewed publications from the past two decades (1995-2016) addressing the nutritional and metabolic status of patients with pancreatic cancer, grouping them into status at the time of diagnosis, status at the time of resection, and status of nutritional support throughout the diagnosis and treatment of pancreatic cancer. Here, we summarize the results of these investigations and evaluate the effectiveness of various types of nutritional support in patients after pancreatectomy for pancreatic adenocarcinoma (PDAC). We outline the following conservative perioperative strategies to optimize patient outcomes and guide the care of these patients: (1) patients with albumin 10% should postpone surgery and begin aggressive nutrition supplementation; (2) patients with albumin endocrine and exocrine pancreatic insufficiency alongside implementation of appropriate treatment to improve the patient's quality of life.

  5. Diet and Pancreatic Cancer Prevention

    Full Text Available Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

Data obtained from a pre-existing base from hospitalized patients with diagnosis of acute necrotizing pancreatitis in the specialized unit of "Unidad de Pancreatitis Aguda Grave del Hospital Nacional Edgardo Rebagliati Martins" between 2000 and 2010. Data included patients with diagnosis of acute necrotizing pancreatitis, of ages 18 and over. Data from 215 patients with acute necrotizing pancreatitis was included. Patients from Group A represented 32% (68) and from Group B 68% (147). Group A had a average of 39 hospitalized days and Group B had an average of 56 days (p=0.01). From Group A 22% had more than 50% of necrosis while 43% of Group B had this extension of necrosis (p pancreatitis, based on the presence of necrosis, behave likewise. It is an extended necrosis, described as more than 50% of pancreatic necrosis, and not the presence itself which will determine additional complications during the course of disease and a greater mortality.

    Advances over the past decade have indicated that a complex interplay between environmental factors, genetic predisposition, alcohol abuse, and smoking lead towards the development of chronic pancreatitis. Chronic pancreatitis is a complex disorder that causes significant and chronic incapacity in patients and a substantial burden on the society. Major advances have been made in the etiology and pathogenesis of this disease and the role of genetic predisposition is increasingly coming to the fore. Advances in noninvasive diagnostic modalities now allow for better diagnosis of chronic pancreatitis at an early stage of the disease. The impact of these advances on surgical treatment is beginning to emerge, for example, patients with certain genetic predispositions may be better treated with total pancreatectomy versus lesser procedures. Considerable controversy remains with respect to the surgical management of chronic pancreatitis. Modern understanding of the neurobiology of pain in chronic pancreatitis suggests that a window of opportunity exists for effective treatment of the intractable pain after which central sensitization can lead to an irreversible pain syndrome in patients with chronic pancreatitis. Effective surgical procedures exist for chronic pancreatitis; however, the timing of surgery is unclear. For optimal treatment of patients with chronic pancreatitis, close collaboration between a multidisciplinary team including gastroenterologists, surgeons, and pain management physicians is needed.

    Patients with a first episode of acute pancreatitis can develop recurrent or chronic pancreatitis (CP). However, little is known about the incidence or risk factors for these events. We performed a cross-sectional study of 669 patients with a first episode of acute pancreatitis admitted to 15 Dutch hospitals from December 2003 through March 2007. We collected information on disease course, outpatient visits, and hospital readmissions, as well as results from imaging, laboratory, and histology studies. Standardized follow-up questionnaires were sent to all available patients to collect information on hospitalizations and interventions for pancreatic disease, abdominal pain, steatorrhea, diabetes mellitus, medications, and alcohol and tobacco use. Patients were followed up for a median time period of 57 months. Primary end points were recurrent pancreatitis and CP. Risk factors were evaluated using regression analysis. The cumulative risk was assessed using Kaplan-Meier analysis. Recurrent pancreatitis developed in 117 patients (17%), and CP occurred in 51 patients (7.6%). Recurrent pancreatitis developed in 12% of patients with biliary disease, 24% of patients with alcoholic etiology, and 25% of patients with disease of idiopathic or other etiologies; CP occurred in 3%, 16%, and 10% of these patients, respectively. Etiology, smoking, and necrotizing pancreatitis were independent risk factors for recurrent pancreatitis and CP. Acute Physiology and Chronic Health Evaluation II scores at admission also were associated independently with recurrent pancreatitis. The cumulative risk for recurrent pancreatitis over 5 years was highest among smokers at 40% (compared with 13% for nonsmokers). For alcohol abusers and current smokers, the cumulative risks for CP were similar-approximately 18%. In contrast, the cumulative risk of CP increased to 30% in patients who smoked and abused alcohol. Based on a retrospective analysis of patients admitted to Dutch hospitals, a first

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

    Pediatric acute pancreatitis has been on the rise in the last decades, with an incidence close to adult pancreatitis. In the majority of cases acute pancreatitis resolves spontaneously, but in a subset of children the disease progresses to severe acute pancreatitis with attendant morbidity and mortality. Pediatric acute pancreatitis in this era is recognized as a separate entity from adult acute pancreatitis given that the causes and disease outcomes are different. There are slow but important advances made in understanding the best management for acute pancreatitis in children from medical, interventional, and surgical aspects. Supportive care with fluids, pain medications, and nutrition remain the mainstay for acute pancreatitis management. For complicated or severe pancreatitis, specialized interventions may be required with endoscopic or drainage procedures. Surgery has an important but limited role in pediatric acute pancreatitis.

    Since ancient times the increase of size and hardness sometimes presented by the abdominal structure known as the pancreas has attracted attention. Portal was the first to describe the clinical signs of chronic pancreatitis in 1803. In 1815, Fleischman speculated about the potential role of excessive alcohol consumption. Comfort coined the term "chronic relapsing pancreatitis" in 1946 and described hereditary pancreatitis 6 years later. Zuidema defined tropical pancreatitis in 1959 and 2 years later Sarles described another form of pancreatitis to which Yoshida gave the name autoimmune pancreatitis in 1995. Groove pancreatitis was described by Potet in 1970. Obstructive pancreatitis was defined in 1984 and Ammann identified idiopathic pancreatitis 3 years later. This article gives a historical account of the pioneers who developed the knowledge of how to assess the characteristics that allowed the different forms of chronic pancreatitis to be defined.

    The classification of accumulative patterns with the pancreatic scintigram findings of chronic pancreatitis and carcinoma of the pancreas were compared with endoscopic retrograde pancreatography (ERP) findings and Pancreozymin-Secretin test (P-S test). I) The frequency of pancreatic cancer was 93%, whilst, the chronic pancreatitis was 88% in the abnormal pancreatic scintigram. II) In the scintigram the type II (localyzed defect shadows) of pancreatic cancer was comparatively high and it is proportional to evidence. derived from ERP. Localized diagnostic certainty is helpful, although the two tests are related. The P-S test is only restricted to the carcinoma of head, whilst, scintigram is more useful to detect the carcinoma of the body and tail of the pancreas. III) As for the chronic pancreatitis, there are various accumulative patterns. This is resemblance to that of ERP findings, but in the P-S normal test, it showed discrepancy in part of the result. Particularly, in the type I (slightly generalized low uptake with density silhouette) and type II. Therefore in order to obtain an accurate diagnosis, it is essential to have both the P-S test and scintigram. (author)

  1. Pancreatic islet transplantation

    2009-09-01

    Full Text Available Abstract Background No formulation of exogenous insulin available to date has yet been able to mimic the physiological nictemeral rhythms of this hormone, and despite all engineering advancements, the theoretical proposal of developing a mechanical replacement for pancreatic β cell still has not been reached. Thus, the replacement of β cells through pancreas and pancreatic islet transplantation are the only concrete alternatives for re-establishing the endogenous insulin secretion in type 1 diabetic patients. Since only 1 to 1.5% of the pancreatic mass corresponds to endocrine tissue, pancreatic islets transplantation arises as a natural alternative. Data from the International Islet Transplant Registry (ITR from 1983 to December 2000 document a total of 493 transplants performed around the world, with progressively worse rates of post-transplant insulin independence. In 2000, the "Edmonton Protocol" introduced several modifications to the transplantation procedure, such as the use of a steroid-free immunosuppression regimen and transplantation of a mean islet mass of 11,000 islet equivalents per kilogram, which significantly improved 1-year outcomes. Although the results of a 5-year follow-up in 65 patients demonstrated improvement in glycemic instability in a significant portion of them, only 7.5% of the patients have reached insulin independence, indicating the need of further advances in the preservation of the function of transplanted islet. In addition to the scarcity of organs available for transplantation, islets transplantation still faces major challenges, specially those related to cell loss during the process of islet isolation and the losses related to the graft site, apoptosis, allorejection, autoimmunity, and immunosuppression. The main strategies to optimize islet transplantation aim at improving all these aspects. Conclusion Human islet transplantation should be regarded as an intervention that can decrease the frequency of

    2010-01-01

    A 25-year-old caucasian lady presented to the Accident & Emergency department complaining of acute onset severe epigastric pain radiating through to the back with associated nausea and vomiting. A diagnosis of acute pancreatitis was made. Symptoms commenced after the third dose of Metronidazole therapy prescribed for a recurrent periodontal abscess. The patient described a similar episode 10 months previously. On neither occasion were any other medications being taken, there was no history of alcohol abuse and no other gastro-intestinal aetiology could be identified on imaging. Symptoms resolved quickly upon discontinuation of the antibiotic agent. We conclude therefore that Metronidazole can reasonably be identified as the only potential causative agent.

    A patient who underwent 95% pancreatectomy with autotransplantation of the body and tail of the gland to the femoral area for chronic pancreatitis is presented. The pain resolved, and the patient's blood glucose level remained within normal limits. High levels of insulin were found in the iliac vein on the transplanted side. Patency of the graft was demonstrated by technetium scan and arteriography and followed by a color-coded Doppler imaging system. Segmental pancreatic autotransplantation offers a method of relieving pain with preservation of endocrine function in selected patients with chronic pancreatitis.

    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.

    2015-01-01

    Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On the other hand, the release of extracellular hemoglobin into the circulation from the ascitic fluid in severe necrotizing pancreatitis enhances lipid peroxidation in plasma and the inflammatory infiltrate into the lung and up-regulates the HIF–VEGF pathway, contributing to the systemic inflammatory response. Therefore, redox signaling and oxidative stress contribute to the local and systemic inflammatory response during acute pancreatitis. PMID:25778551

    In spite of continuous research efforts directed at early detection and treatment of pancreatic cancer, the outlook for patients affected by the disease remains dismal. With most cases still being diagnosed at advanced stages, no improvement in survival prognosis is achieved with current diagnostic imaging approaches. In the absence of a dominant precancerous condition, several risk factors have been identified including family history, chronic pancreatitis, smoking, diabetes mellitus, as well as certain genetic disorders such as hereditary pancreatitis, cystic fibrosis, familial atypical multiple mole melanoma, and Peutz-Jeghers and Lynch syndromes. Most pancreatic carcinomas, however, remain sporadic. Current progress in experimental molecular techniques has enabled detailed understanding of the molecular processes of pancreatic cancer development. According to the latest information, malignant pancreatic transformation involves multiple oncogenes and tumor-suppressor genes that are involved in a variety of signaling pathways. The most characteristic aberrations (somatic point mutations and allelic losses) affect oncogenes and tumor-suppressor genes within RAS, AKT and Wnt signaling, and have a key role in transcription and proliferation, as well as systems that regulate the cell cycle (SMAD/DPC, CDKN2A/p16) and apoptosis (TP53). Understanding of the underlying molecular mechanisms should promote development of new methodology for early diagnosis and facilitate improvement in current approaches for pancreatic cancer treatment.

    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. Since patients suffering from chronic pancreatitis experience severe pain, opioids are often prescribed as pain treatment. Opioids have intrinsic effects on gastrointestinal motility and hence can modify the absorption of other drugs taken at the same time. Furthermore, the increased fluid absorption caused by opioids will decrease water available for drug dissolution and may hereby affect absorption of the drug. As stated above many factors can influence drug absorption and metabolism in patients with chronic pancreatitis. The factors may not have clinical relevance, but may explain inter-individual variations in responses to a given drug, in patients with chronic pancreatitis.

    Chronic pancreatitis (CP) is an inflammatory disease of the pancreas characterized by progressive fibrotic destruction of the pancreatic secretory parenchyma. Despite the heterogeneity in pathogenesis and involved risk factors, processes such as necrosis/apoptosis, inflammation or duct obstruction are involved. This fibrosing process ultimately leads to progressive loss of the lobular morphology and structure of the pancreas, deformation of the large ducts and severe changes in the arrangement and composition of the islets. These conditions lead to irreversible morphological and structural changes resulting in impairment of both exocrine and endocrine functions. The prevalence of the disease is largely dependent on culture and geography. The etiological risk-factors associated with CP are multiple and involve both genetic and environmental factors. Throughout this review the M-ANNHEIM classification system will be used, comprising a detailed description of risk factors such as: alcohol-consumption, nicotine-consumption, nutritional factors, hereditary factors, efferent duct factors, immunological factors and miscellaneous and rare metabolic factors. Increased knowledge of the different etiological factors may encourage the use of further advanced diagnostic tools, which potentially will help clinicians to diagnose CP at an earlier stage. However, in view of the multi factorial disease and the complex clinical picture, it is not surprising that treatment of patients with CP is challenging and often unsuccessful.

    This research aimed to discover the potential of inoculated Aquilaria malaccensis extract as a new and safe lipase inhibitor. The phenolic compounds in this plant are expected to promote inhibitory activity towards pancreatic lipase enzyme. Inoculated Aquilaria malaccensis was selected for this research, wherein the parts of this species (bark and leaves) were extracted via hydro distillation process. The extracts of this plant which are hydrosol, oil, and leaves were analyzed for phyto chemical compound via Fourier Transform Infrared Spectroscopy (FTIR). FTIR analysis of the extracts of inoculated Aquilaria malccensis revealed the presence of hydroxyl functional group in both leaves and hydrosol extracts but absence in oil. This validate the presence of phenolic compound in hydrosol and leaves extract. Therefore, the leaves and hydrosol extracts have potential as an anti-obesity agent by inhibiting pancreatic lipase.

    Full Text Available The pancreas is an unusual location for metastases from other primary cancers. Rarely, pancreatic metastases from kidney or colorectal cancers have been reported. However, a variety of other cancers may also spread to the pancreas. We report an exceptional case of pancreatic metastasis from prostate cancer. Differences in management between primary and secondary pancreatic tumors make recognition of metastases to the pancreas an objective of first importance. Knowledge of unusual locations for metastatic spread will reduce diagnostic delay and lead to a timely delivery of an appropriate treatment.

    Acute pancreatitis is a common disease that can progress to gland necrosis, which imposes significant risk of morbidity and mortality. In general, the treatment for pancreatitis is a supportive therapy. However, there are several reasons to escalate to surgery or another intervention. This review discusses the pathophysiology as well as medical and interventional management of necrotizing pancreatitis. Current evidence suggests that patients are best served by delaying interventions for at least 4 weeks, draining as a first resort, and debriding recalcitrant tissue using minimally invasive techniques to promote or enhance postoperative recovery while reducing wound-related complications.

    Sun exposure has been associated with lower death rates for pancreatic cancer in ecological studies. Skin exposure to solar ultra-violet B radiation induces cutaneous production of precursors to 25-hydroxy (OH) vitamin D (D) and is considered the primary contributor to vitamin D status in most populations. Pancreatic islet and duct cells express 25-(OH) D3-1α-hydroxylase that generates the biologically active 1,25-dihydroxy(OH)2 D form. Thus, 25(OH)D concentrations could affect pancreatic fun...

    Pancreatic cancer is currently one of the deadliest of the solid malignancies. However, surgery to resect neoplasms of the pancreas is safer and less invasive than ever, novel drug combinations have been shown to improve survival, advances in radiation therapy have resulted in less toxicity, and enormous strides have been made in our understanding of the fundamental genetics of pancreatic cancer. These advances provide hope but they also increase the complexity of caring for patients. It is clear that multidisciplinary care that provides comprehensive and coordinated evaluation and treatment is the most effective way to manage patients with pancreatic cancer. PMID:23856911

  5. Pancreatic tissue fluid pressure and pain in 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...

    Chronic pancreatitis is suggested to be one of the risk factors for the development of pancreatic cancer. The aim of this study was to confirm the high incidence of pancreatic cancer in patients with chronic pancreatitis in Japan and to determine the factors associated with the risk for pancreatic cancer in patients with chronic pancreatitis. The working group of the Research Committee of Intractable Disease supported by the Ministry of Health, Labour and Welfare of Japan carried out a nationwide survey to investigate the relationship between chronic pancreatitis and pancreatic cancer. This retrospective study included patients diagnosed with chronic pancreatitis who had had at least 2 years of follow-up. They were contacted through 22 Japanese referral centers experienced in the management of chronic pancreatitis. The standardized incidence ratio (95 CI) of pancreatic cancer was 11.8 (7.1-18.4). The incidence of pancreatic cancer was significantly lower in patients who had received surgery for chronic pancreatitis than in those who had not undergone surgery (hazard ratio estimated by Cox regression 0.11; 95% CI, 0.0014-0.80; P = .03). Patients who continued to drink alcohol after diagnosis of chronic pancreatitis showed a significantly higher incidence of pancreatic cancer than those who stopped drinking after diagnosis of chronic pancreatitis (hazard ratio, 5.07; 95% CI, 1.13-22.73; P = .03). This study confirmed that chronic pancreatitis is an important risk factor for the development of pancreatic cancer in Japan. Patients who underwent surgery for the treatment of chronic pancreatitis had significantly lower incidences of pancreatic cancer. Surgery for chronic pancreatitis may inhibit the development of pancreatic cancer in patients with chronic pancreatitis. Copyright © 2013 Mosby, Inc. All rights reserved.

    Full Text Available Pancreatic cancer is an aggressive malignancy with a poor prognosis. The disease and its treatment can cause significant nutritional impairments that often adversely impact patient quality of life (QOL. The pancreas has both exocrine and endocrine functions and, in the setting of cancer, both systems may be affected. Pancreatic exocrine insufficiency (PEI manifests as weight loss and steatorrhea, while endocrine insufficiency may result in diabetes mellitus. Surgical resection, a central component of pancreatic cancer treatment, may induce or exacerbate these dysfunctions. Nutritional and metabolic dysfunctions in patients with pancreatic cancer lack characterization, and few guidelines exist for nutritional support in patients after surgical resection. We reviewed publications from the past two decades (1995–2016 addressing the nutritional and metabolic status of patients with pancreatic cancer, grouping them into status at the time of diagnosis, status at the time of resection, and status of nutritional support throughout the diagnosis and treatment of pancreatic cancer. Here, we summarize the results of these investigations and evaluate the effectiveness of various types of nutritional support in patients after pancreatectomy for pancreatic adenocarcinoma (PDAC. We outline the following conservative perioperative strategies to optimize patient outcomes and guide the care of these patients: (1 patients with albumin < 2.5 mg/dL or weight loss > 10% should postpone surgery and begin aggressive nutrition supplementation; (2 patients with albumin < 3 mg/dL or weight loss between 5% and 10% should have nutrition supplementation prior to surgery; (3 enteral nutrition (EN should be preferred as a nutritional intervention over total parenteral nutrition (TPN postoperatively; and, (4 a multidisciplinary approach should be used to allow for early detection of symptoms of endocrine and exocrine pancreatic insufficiency alongside implementation of

    Magnetic resonance (MR) imaging plays an important role in the diagnosis and staging of acute and chronic pancreatitis and may represent the best imaging technique in the setting of pancreatitis due to its unmatched soft tissue contrast resolution as well as non-ionizing nature and higher safety profile of intravascular contrast media, making it particularly valuable in radiosensitive populations such as pregnant patients, and patients with recurrent pancreatitis requiring multiple follow-up examinations. Additional advantages include the ability to detect early forms of chronic pancreatitis and to better differentiate adenocarcinoma from focal chronic pancreatitis. This review addresses new trends in clinical pancreatic MR imaging emphasizing its role in imaging all types of acute and chronic pancreatitis, pancreatitis complications and other important differential diagnoses that mimic pancreatitis.

    Full Text Available Groove Pancreatitis (GP is a rare form of focal chronic pancreatitis involving the pancreatico-duodenal groove (PDG. GP was first described by Becker in 1973. Though, GP has been described so many years ago, it is still unfamiliar among most physicians because of lack of sufficient case studies and clinical similarity of GP to conventional pancreatitis. Imaging based differentiation of GP from other lesions, like pancreatic and periampullary adenocarcinoma is also not possible in all the cases, unless there are typical findings favoring GP. Since, the line of treatment and outcome is totally different in these two conditions, appreciation of the fine differences between these two entities is very significant. Groove pancreatitis is symptomatically treated with medicines and only for patients with continuous and severe symptoms which are not amenable to medical treatment surgical management is considered. Radiological differentiation of GP from pancreatic and periampullary malignancies will help to avoid unnecessary surgery in the initial stages. We report two cases of GP, one of pure and other of segmental form where we found typical imaging features which pointed to the diagnosis of GP with a small discussion about the Computed tomography (CT and Magnetic Resonance Imaging (MRI appearance of this entity as well as its differential diagnosis.

    Chronic pancreatitis (CP) is an irreversible, inflammatory process, which is characterized by progressive fibrosis of the pancreas and leads to abdominal pain, endocrine and exocrine insufficiency. Surgical therapy is indicated by the absence of pain relief and local complications. The target of the surgical approach is to relieve the pancreatic and bile ducts and resection of the fibrotic and calcified parenchyma. Drainage procedures, such as the Partington-Rochelle method, are used in patients with isolated congestion of the pancreatic duct without further organ complications, such as inflammatory processes of the pancreatic head; however, patients with CP often have an inflammatory swelling of the pancreatic head. In this case classical pancreatoduodenectomy (PD) or organ-sparing duodenum-preserving pancreatic head resection (DPPHR) with its various techniques (e.g. Beger, Frey, Bern and V‑shape) can be applied. Due to similar long-term results PD should be carried out in cases of suspicion or detection of malignancies and DPPHR for treatment of CP.

    Pancreatic duct stone (PDS) is a common complication of chronic pancreatitis. Surgery is a common therapeutic option for PDS. In this study we assessed the surgical procedures for PDS in patients with chronic pancreatitis at our hospital. Between January 2004 and September 2009, medical records from 35 patients diagnosed with PDS associated with chronic pancreatitis were retrospectively reviewed and the patients were followed up for up to 67 months. The 35 patients underwent ultrasonography, computed tomography, or both, with an overall accuracy rate of 85.7%. Of these patients, 31 underwent the modified Puestow procedure, 2 underwent the Whipple procedure, 1 underwent simple stone removal by duct incision, and 1 underwent pancreatic abscess drainage. Of the 35 patients, 28 were followed up for 4-67 months. There was no postoperative death before discharge or during follow-up. After the modified Puestow procedure, abdominal pain was reduced in patients with complete or incomplete stone clearance (P>0.05). Steatorrhea and diabetes mellitus developed in several patients during a long-term follow-up. Surgery, especially the modified Puestow procedure, is effective and safe for patients with PDS associated with chronic pancreatitis. Decompression of intraductal pressure rather than complete clearance of all stones predicts postoperative outcome.

    Autoimmune pancreatitis (AIP) is a rare disease, the pathophysiological understanding of which has been greatly improved over the last years. The most common form, type 1 AIP belongs to the IgG4-related diseases and must be distinguished from type 2 AIP, which is a much rarer entity associated with chronic inflammatory bowel disease. Clinically, there is an overlap with pancreatic cancer. Imaging and further criteria, such as serological and histological parameters are utilized for a differentiation between both entities in order to select the appropriate therapy and to avoid the small but ultimately unnecessary number of pancreatectomies. The diagnostics of AIP are complex, whereby the consensus criteria of the International Association of Pancreatology have become accepted as the parameters for discrimination. These encompass five cardinal criteria and one therapeutic criterion. By applying these criteria AIP can be diagnosed with a sensitivity of 84.9 %, a specificity of 100 % and an accuracy of 93.8 %. The diagnosis of AIP is accomplished by applying several parameters of which two relate to imaging. As for the routine diagnostics of the pancreas these are ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI). Important for the differential diagnosis is the exclusion of signs of local and remote tumor spread for which CT and MRI are established. The essential diagnostic parameter of histology necessitates sufficient sample material, which cannot usually be acquired by a fine needle biopsy. CT or MRI are the reference standard methods for identification of the optimal puncture site and imaging-assisted (TruCut) biopsy. In patients presenting with unspecific upper abdominal pain, painless jaundice combined with the suspicion of a pancreatic malignancy in imaging but a mismatch of secondary signs of malignancy, AIP should also be considered as a differential diagnosis. As the diagnosis of AIP only partially relies on imaging radiologists also

    1983-01-01

    Pancreatic scintigraphy was performed on 67 diabetic patients (42 males and 25 females) in order to study exocrine pancreatic functions in primary diabetes. Relationships between visualization and the onset age, sex, morbid period, presence or absence of retinitis, good or poor control of blood glucose control and the therapeutic modality of diabetes were examined. Abnormality was detected in 34 cases (50.7%), being frequent among male patients in their 50s. The more serious the diabetes, i.e., with a longer morbid period, poorer blood glucose control and worse retinitis, the higher was the frequency of abnormality in pancreatic visualization. The frequency of abnormality was high in association with insulin treatment, oral tablets and single dietary treatment in that order. The more severe the hypoinsulinism, the higher was the frequency of abnormality. This technique can be used as a screening means for exocrine pancreatic function tests on diabetics. (Chiba, N.)

    Gastrointestinal toxicity is uncommon among patients treated with angiotensin II receptor antagonists. A 58-year-old man presented with nausea, vomiting and constant pain in the epigastrium that radiated to the flanks. He received treatment with valsartan (160 mg daily) for hypertension. The clinical, biochemical and radiological findings were compatible with a diagnosis of acute pancreatitis. After the patient achieved a clinical and biochemical recovery, the valsartan therapy was started again. Six weeks later, he returned to the hospital with an attack of pancreatitis. Subsequently, he returned with repeated attacks of pancreatitis twice, and the valsartan was discontinued. Ten months after the treatment, the patient had no complaints. When severe abdominal symptoms occur for no apparent reason during treatment with valsartan, a diagnosis of pancreatitis should be considered.

    Background To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. Methods The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. Results A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Conclusions Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation. Randomized studies should compare the respective outcomes of robot-assisted, laparoscopic and open pancreatic surgery. PMID:23216773

    Clinical pancreatic islet transplantation can be considered one of the safest and least invasive transplant procedures. Remarkable progress has occurred in both the technical aspects of islet cell processing and the outcomes of clinical islet transplantation. With >1,500 patients treated since 2000, this therapeutic strategy has moved from a curiosity to a realistic treatment option for selected patients with type 1 diabetes mellitus (that is, those with hypoglycaemia unawareness, severe hypoglycaemic episodes and glycaemic lability). This Review outlines the techniques required for human islet isolation, in vitro culture before the transplant and clinical islet transplantation, and discusses indications, optimization of recipient immunosuppression and management of adjunctive immunomodulatory and anti-inflammatory strategies. The potential risks, long-term outcomes and advances in treatment after the transplant are also discussed to further move this treatment towards becoming a more widely available option for patients with type 1 diabetes mellitus and eventually a potential cure.

    Full Text Available Postpolypectomy bleeding and perforation are the most common complications of colonoscopy. A case of acute pancreatitis and ileus after colonoscopy is described. A 60-year-old woman underwent a gastroscopy and colonoscopy for investigation of iron deficiency anemia. Gastroscopy was normal; however, the colonoscope could not be advanced beyond the splenic flexure due to a tight angulation. Two polypectomies were performed in the descending colon. After the procedure, the patient developed a distended, tender abdomen. Bloodwork was remarkable for an elevated amylase level. An abdominal x-ray and computed tomography scan showed pancreatitis (particularly of the tail, a dilated cecum and a few air-fluid levels. The patient improved within 24 h of a repeat colonoscopy and decompression tube placement. The patient had no risk factors for pancreatitis. The causal mechanism of pancreatitis was uncertain but likely involved trauma to the tail of the pancreas during the procedure. Our patient developed ileus, likely secondary to pancreatitis. The present case is the first report of clinical pancreatitis and ileus associated with colonoscopy.

  1. Pancreatic Stones: Treat or Ignore?

    Directory of Open Access Journals (Sweden)

    DA Howell

    1999-01-01

    Full Text Available Painful, chronic pancreatitis is of complex etiology, but increasing clinical experience suggests that removal of pancreatic duct stones in many cases significantly improves patients’ symptoms. The development and refinement of therapeutic endoscopic retrograde choledochopancreatography have permitted improved access to the pancreatic duct, which makes the development of new techniques of stone fragmentation and fragment removal a much more successful nonsurgical intervention. A major step forward has been the understanding of the safety and efficacy of pancreatic sphincterotomy, which is necessary for the removal of these difficult stones. The recognition that extracorporeal shock wave lithotripsy can be delivered safely with good efficacy has revolutionized the nonsurgical management of pancreatic duct stones. Nevertheless, advanced and sophisticated therapeutic endoscopy is necessary to achieve clearance of the duct, which can generally be accomplished in the majority of selected patients. State-of-the-art treatments are described, and some new approaches using pancreatoscopy and electrohydrolic lithotripsy are discussed. Newly recognized long term complications are reviewed. Finally, it must be recognized that chronic pancreatitis is an ongoing disease that does not have a simple treatment or cure, and frequently represents a process of remissions and relapses requiring interventions and problem solving.

    Pancreatic pseudocyst is a collection of necrotic tissue, old blood and secretions that escaped from the pancreas damaged by pancreatitis, trauma and chronic alcoholism. There is no epithelial cell lining the cystic wall. With the advent of ultrasound and CT more accurate diagnosis can be made. Our study was carried out to analyse the radiological and clinical findings of 32 cases of pancreatic pseudocysts confirmed at Wonju College of Medicine Yonsei University from Jan. 1979 to Aug. 1986. The results are as follows: 1. Male to female ratio was 4.3:1 Incidence was the most common in 4th decades. 2. The most frequent symptom was epigastric pain (100%). 3. In a total of 32 cases, 15 cases had a underlying cause of pancreatitis, 9 cases abdominal trauma. 4. In laboratory findings, serum amylase level was elevated in 23 cases, leucocytosis in 10 cases. 5. On chest films, the lungs were mostly normal. Soft tissue mass density in 12 cases was the most common finding on abdomen films. 6. UGI series were helpful in directing attention by pancreatic pseudocysts' location and size. 7. Ultrasonogram using primary procedure for the detection of pseudocyst (23 cases) disclosed anechoic lesion in 8 cases, mixed echo lesion in 15 cases. Mixed echo patterns, in terms of internal echo patters, were echogenic spots (8 cases), septation and echogenic spots (3 cases), fluid-fluid level (3 cases), etc. 8. CT scanning is the best imaging procedure, providing detailed morphologic information about the pancreatic pseudocyst and surrounding tissue.

    2013-05-01

    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 (ppancreatic components coincidently within 3-D pancreatic tissues. It is a prospect for intravital observation of dynamic events under natural physiological conditions, and might help uncover the key mechanisms of exocrine pancreatic diseases, leading to more effective treatments.

    We had developed the Unifying-Autoimmune-Pancreatitis-Criteria (U-AIP) to diagnose autoimmune pancreatitis (AiP) within the M-ANNHEIM classification of chronic pancreatitis. In 2011, International-Consensus-Diagnostic-Criteria (ICDC) to diagnose AiP have been published. We had applied the U-AIP long before the ICDC were available. The aims of the study were, first, to describe patients with AiP diagnosed by the U-AIP; second, to compare diagnostic accuracies of the U-AIP and other diagnostic systems; third, to evaluate the clinical applicability of the U-AIP. From 1998 until 2008, we identified patients with AiP using U-AIP, Japanese-, Korean-, Asian-, Mayo-HISORt-, Revised-Mayo-HISORt- and Italian-criteria. We retrospectively verified the diagnosis by ICDC and Revised-Japanese-2011-criteria, compared diagnostic accuracies of all systems and evaluated all criteria in consecutive patients with pancreatitis (2009 until 2010, Pancreas-Outpatient-Clinic-Cohort, n = 84). We retrospectively validated our diagnostic approach in consecutive patients with a pancreatic lesion requiring surgery (Surgical-Cohort, n = 98). Overall, we identified 21 patients with AiP. Unifying-Autoimmune-Pancreatitis-Criteria and ICDC presented the highest diagnostic accuracies (each 98.8%), highest Youden indices (each 0.95238), and highest proportions of diagnosed patients (each n = 20/21, U-AIP/ICDC vs. other diagnostic systems, p Pancreatitis-Criteria revealed a satisfactory clinical applicability and offered an additional approach to diagnose AiP.

    Chronic pancreatitis may lead to steatorrhea, enteric hyperoxaluria, and kidney damage. However, the prevalence and determinants of hyperoxaluria in chronic pancreatitis patients as well as its association with renal function decline have not been investigated.We performed an observational study. Urine oxalate to creatinine ratio was assessed on 2 independent random urine samples in consecutive adult patients with chronic pancreatitis followed at the outpatient clinic from March 1 to October 31, 2012. Baseline characteristics and annual estimated glomerular filtration rate (eGFR) change during follow-up were compared between patients with hyper- and normo-oxaluria.A total of 48 patients with chronic pancreatitis were included. The etiology of the disease was toxic (52%), idiopathic (27%), obstructive (11%), autoimmune (6%), or genetic (4%). Hyperoxaluria (defined as urine oxalate to creatinine ratio >32 mg/g) was found in 23% of patients. Multivariate regression analysis identified clinical steatorrhea, high fecal acid steatocrit, and pancreatic atrophy as independent predictors of hyperoxaluria. Taken together, a combination of clinical steatorrhea, steatocrit level >31%, and pancreatic atrophy was associated with a positive predictive value of 100% for hyperoxaluria. On the contrary, none of the patients with a fecal elastase-1 level >100 μg/g had hyperoxaluria. Longitudinal evolution of eGFR was available in 71% of the patients, with a mean follow-up of 904 days. After adjustment for established determinants of renal function decline (gender, diabetes, bicarbonate level, baseline eGFR, and proteinuria), a urine oxalate to creatinine ratio >32 mg/g was associated with a higher risk of eGFR decline.Hyperoxaluria is highly prevalent in patients with chronic pancreatitis and associated with faster decline in renal function. A high urine oxalate to creatinine ratio in patients with chronic pancreatitis is best predicted by clinical steatorrhea, a high acid

    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. Copyright © 2012.

    l-asparaginase has been an element in the treatment for acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma since the late 1960s and remains an essential component of their combination chemotherapy. Among the major toxicities associated with l-asparaginase therapy are pancreatitis, allergic reactions, thrombotic events, hepatotoxicity and hyperlipidaemia. Acute pancreatitis is one of the most common reasons for stopping treatment with l-asparaginase. Short-term complications of asparaginase-associated pancreatitis include development of pseudocysts and pancreatic necrosis. Long-term complications include chronic pancreatitis and diabetes. The pathophysiology of asparaginase-associated pancreatitis remains to be uncovered. Individual clinical and genetic risk factors have been identified, but they are only weak predictors of pancreatitis. This review explores the definition, possible risk factors, treatment and complications of asparaginase-associated pancreatitis. © 2012 Blackwell Publishing Ltd.

    The role of obesity in relation to various disease processes is being increasingly studied, with reports over the last several years increasingly mentioning its association with worse outcomes in acute disease. Obesity has also gained recognition as a risk factor for severe acute pancreatitis (SAP).The mortality in SAP may be as high as 30% and is usually attributable to multi system organ failure (MSOF) earlier in the disease, and complications of necrotizing pancreatitis later [9-11]. To date there is no specific treatment for acute pancreatitis (AP) and the management is largely expectant and supportive. Obesity in general has also been associated with poor outcomes in sepsis and other pathological states including trauma and burns. With the role of unsaturated fatty acids (UFA) as propagators in SAP having recently come to light and with the recognition of acute lipotoxicity, there is now an opportunity to explore different strategies to reduce the mortality and morbidity in SAP and potentially other disease states associated with such a pathophysiology. In this review we will discuss the role of fat and implications of the consequent acute lipotoxicity on the outcomes of acute pancreatitis in lean and obese states and during acute on chronic pancreatitis.

    Full Text Available Acute pancreatitis (AP is an inflammatory disease presenting from mild localized inflammation to severe infected necrotic pancreatic tissue. In the literature, there are a few cases of hypothermia-induced AP. However, the association between hypothermia and AP is still a myth. Generally, mortality from acute pancreatitis is nearly 3–6%. Here, we present a 40-year-old chronic alcoholic female who presented with acute pancreatitis induced by transient hypothermia. A 40-year-old chronic alcoholic female was hypothermic at 81°F on arrival which was improved to 91.7°F with warming blanket and then around 97°F in 8 h. Laboratory tests including complete blood count, lipid panel, and comprehensive metabolic panels were within the normal limit. Serum alcohol level was 0.01, amylase 498, lipase 1,200, ammonia 26, serum carboxyhemoglobin level 2.4, and β-HCG was negative. The entire sepsis workup was negative. During rewarming period, she had one episode of witnessed generalized tonic-clonic seizure. It was followed by transient hypotension. Fluid challenge was successful with 2 L of normal saline. Sonogram (abdomen showed fatty liver and trace ascites. CAT scan (abdomen and pelvis showed evidence of acute pancreatitis without necrosis, peripancreatic abscess, pancreatic mass, or radiopaque gallstones. The patient was managed medically and later discharged from the hospital on the 4th day as she tolerated a normal low-fat diet. In our patient, transient hypothermia from chronic alcohol abuse and her social circumstances might predispose to microcirculatory disturbance resulting in acute pancreatitis. Early and aggressive fluid resuscitation prevents complications.

    A 42 year-old woman with severe acute pancreatitis had drainage of the pancreatic bed, cholecystostomy and jejunostomy on admission, but symptoms were not improved. Fourteen days after admission, clinical sepsis and septisemia were recognized. Dynamic CT scanning of the pancreas showed near total pancreatic necrosis. Symptoms were improved after necrosectomy of the pancreas and debridement of the peripancreatic necrotic tissue were performed. Our experience suggests the usefulness of dynamic CT scanning for detection of pancreatic necrosis in severe acute pancreatitis. (author)

    Acute pancreatitis may be the first manifestation of pancreatic cancer. The aim of this study was to assess the risk of pancreatic cancer after a first episode of acute pancreatitis. Between March 2004 and March 2007, all consecutive patients with a first episode of acute pancreatitis were prospectively registered. Follow-up was based on hospital records audit, radiological imaging, and patient questionnaires. Outcome was stratified based on the development of chronic pancreatitis. We included 731 patients. The median follow-up time was 55 months. Progression to chronic pancreatitis was diagnosed in 51 patients (7.0%). In this group, the incidence rate per 1000 person-years for developing pancreatic cancer was 9.0 (95% confidence interval, 2.3-35.7). In the group of 680 patients who did not develop chronic pancreatitis, the incidence rate per 1000 person-years for developing pancreatic cancer in this group was 1.1 (95% confidence interval, 0.3-3.3). Hence, the rate ratio of pancreatic cancer was almost 9 times higher in patients who developed chronic pancreatitis compared with those who did not (P = 0.049). Although a first episode of acute pancreatitis may be related to pancreatic cancer, this risk is mainly present in patients who progress to chronic pancreatitis.

    In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.

    To investigate the radiological findings prognostic for the development of pancreatic adenocarcinoma in a cohort of patients with hepatocellular carcinoma, using multiphasic computed tomography (CT). A case-cohort study performed in a single university hospital. A database of patients who received hepatocellular carcinoma (HCC) treatment and trimonthly follow-up with four-phase dynamic CT was used (n = 1848). The cohort group was randomly extracted from the database (n = 103). The case group comprised nine patients from the database who developed pancreatic adenocarcinoma. The radiological findings were assessed during follow-up (average, 32 months). The incidence of pancreatic mass, inhomogeneous parenchyma, loss of fatty marbling and main pancreatic duct dilatation gradually increased from 4 to 13 months before the diagnosis of pancreatic adenocarcinoma. There was a significantly higher incidence of pancreatic mass, inhomogeneous parenchyma and loss of fatty marbling on CT at baseline (average, 34 months before diagnosis) in the case group compared with the cohort group (P values < 0.01) and those findings at baseline were revealed as prognostic factors for pancreatic carcinogenesis, respectively (log-rank test, P values < 0.001). Several radiological findings observed on multiphasic CT can assist in predicting pancreatic carcinogenesis well in advance. (orig.)

    Endoscopy and surgery are the treatment modalities of choice for patients with chronic pancreatitis and dilated pancreatic duct (obstructive chronic pancreatitis). Physicians face, without clear consensus, the choice between endoscopy or surgery for this group of patients. To assess and compare the effects and complications of surgical and endoscopic interventions in the management of pain for obstructive chronic pancreatitis. We searched the following databases in The Cochrane Library: CENTRAL (2014, Issue 2), the Cochrane Database of Systematic Reviews (2014, Issue 2), and DARE (2014, Issue 2). We also searched the following databases up to 25 March 2014: MEDLINE (from 1950), Embase (from 1980), and the Conference Proceedings Citation Index - Science (CPCI-S) (from 1990). We performed a cross-reference search. Two review authors independently performed the selection of trials. All randomised controlled trials (RCTs) of endoscopic or surgical interventions in obstructive chronic pancreatitis. We included trials comparing endoscopic versus surgical interventions as well as trials comparing either endoscopic or surgical interventions to conservative treatment (i.e. non-invasive treatment modalities). We included relevant trials irrespective of blinding, the number of participants randomised, and the language of the article. We used standard methodological procedures expected by The Cochrane Collaboration. Two authors independently extracted data from the articles. We evaluated the methodological quality of the included trials and requested additional information from study authors in the case of missing data. We identified three eligible trials. Two trials compared endoscopic intervention with surgical intervention and included a total of 111 participants: 55 in the endoscopic group and 56 in the surgical group. Compared with the endoscopic group, the surgical group had a higher proportion of participants with pain relief, both at middle/long-term follow-up (two to

    While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

    Objective: To assess the CT manifestations and diagnostic value in the pancreatic tuberculosis(PTB)with review of the literatures. Methods: All cases of PTB proved by surgery or biopsy were examined with plain and enhanced CT scans. Results: The CT findings in one case with multiple-nodular type of PTB were diffuse enlargement of the pancreas with multiple, nodular, and low-density lesions; The nodular lesions had peripheral enhancement. 7 cases of local type of PTB encroached on pancreatic head. 4 cases showed local soft tissue masses with multiple flecked calcifications in 2 cases and mild enhancement in one case; Cystic masses was found in 2 cases, with mural calcification in 1 case and multi-loculated cystic mass in 1 case, respectively; Massive pancreatic head calcification was demonstrated in one case. In these 8 cases of PTB, the lesion extended out of pancreas in 4 cases, including abdominal tuberculous lymph nodes, tuberculous peritonitis, and hepatosplenic tuberculosis. Conclusion: CT findings of PTB were various but had some characteristics. Pancreatic masses with multiple flecked calcification or mild enhancement could suggest the diagnosis. Abdominal tuberculosis accompanied with the pancreatic lesion, especially tuberculous lymph nodes, was highly suggestive of the diagnosis of PTB

  3. Cystic Lesions in Autoimmune Pancreatitis

    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

    Pancreatic pseudocyst occurs as a complication of pancreatitis or trauma, which results in the escape of pancreatitis enzymes from the parenchyma or ductal system of pancreas. At that time, serum amylase may have retuned to normal level, and the patient may be subjectively asymptomatic. In this phase, the radiologic findings are relatively greater significance than laboratory data. In the conventional radiologic study, pancreatic pseudocyst have been frequently confused with other retroperitoneal mass, but recently with clinical application of ultrasound and CT scan, more accurate diagnosis can be obtained. The brief results are as follows: 1. Male to female ratio was 3 : 2 in 15 patients. Incidence was more common in young adult age. Most frequent symptom was epigastric pain, and which was noted in 11 cases of patients. 7 cases of patients had past history of abdominal trauma and past history of pancreatitis was only in 1 case. Most common laboratory findings was leukocytosis in 8 cases of patients and elevated serum amylase was also noted in 7 cases. 2. In each 5 cases of patients, plain chest roentgenologic evidence of left side pleural effusion and hemidiaphragm elevation were observed. 3. On flat abdomen film, soft mass shadow was visualized in 8 cases of patients. On UGI series, evidence of retrogastric space widening was observed in 11 cases of patients. 4. The location of pseudocyst is mainly in body and tail of pancrease in 11 cases of patients. 5. More accureable diagnosis can be obtained through application of ultrasound and CT scan

    Pancreatic exocrine insufficiency (PEI) occurs when the amounts of enzymes secreted into the duodenum in response to a meal are insufficient to maintain normal digestive processes. The main clinical consequence of PEI is fat maldigestion and malabsorption, resulting in steatorrhoea. Pancreatic exocrine function is commonly assessed by conducting a 3-day faecal fat test and by measuring levels of faecal elastase-1 and serum trypsinogen. Pancreatic enzyme replacement therapy is the mainstay of treatment for PEI. In adults, the initial recommended dose of pancreatic enzymes is 25,000 units of lipase per meal, titrating up to a maximum of 80,000 units of lipase per meal. In infants and children, the initial recommended dose of pancreatic enzymes is 500 units of lipase per gram of dietary fat; the maximum daily dose should not exceed 10,000 units of lipase per kilogram of bodyweight. Oral pancreatic enzymes should be taken with meals to ensure adequate mixing with the chyme. Adjunct therapy with acid-suppressing agents may be useful in patients who continue to experience symptoms of PEI despite high-dose enzyme therapy. A dietitian experienced in treating PEI should be involved in patient management. Dietary fat restriction is not recommended for patients with PEI. Patients with PEI should be encouraged to consume small, frequent meals and to abstain from alcohol. Medium-chain triglycerides do not provide any clear nutritional advantage over long-chain triglycerides, but can be trialled in patients who fail to gain or to maintain adequate bodyweight in order to increase energy intake.

    Abdominal tuberculosis (TB) is one of the most common forms of extra-pulmonary tuberculosis and is responsible for considerable morbidity and mortality globally. Tuberculosis can involve any part of the gastrointestinal tract from mouth to anus, the peritoneum, liver, spleen and the pancreatobiliary system. The occurrence of abdominal TB is independent of pulmonary disease in most patients, with a reported incidence of co-existing pulmonary disease varying from 6 to 38% worldwide. We report a case of pancreatic tuberculosis also involving the vertebrae, which was initially treated as a case of pancreatic cancer. (author)

    Fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) has been widely used for the diagnosis of pancreatic cancer. Because autoimmune pancreatitis is easily misdiagnosed as pancreatic cancer and can be tested for by FDG-PET analysis based on the presence of suspected pancreatic cancer, we attempted to clarify the differences in FDG-PET findings between the two conditions. We compared FDG-PET findings between 15 patients with autoimmune pancreatitis and 26 patients with pancreatic cancer. The findings were evaluated visually or semiquantitatively using the maximum standardized uptake value and the accumulation pattern of FDG. FDG uptake was found in all 15 patients with autoimmune pancreatitis, whereas it was found in 19 of 26 patients (73.1%) with pancreatic cancer. An accumulation pattern characterized by nodular shapes was significantly more frequent in pancreatic cancer, whereas a longitudinal shape indicated autoimmune pancreatitis. Heterogeneous accumulation was found in almost all cases of autoimmune pancreatitis, whereas homogeneous accumulation was found in pancreatic cancer. Significantly more cases of pancreatic cancer showed solitary localization, whereas multiple localization in the pancreas favored the presence of autoimmune pancreatitis. FDG uptake by the hilar lymph node was significantly more frequent in autoimmune pancreatitis than in pancreatic cancer, and uptake by the lachrymal gland, salivary gland, biliary duct, retroperitoneal space, and prostate were seen only in autoimmune pancreatitis. FDG-PET is a useful tool for differentiating autoimmune pancreatitis from suspected pancreatic cancer, if the accumulation pattern and extrapancreatic involvement are considered. IgG4 measurement and other current image tests can further confirm the diagnosis. (author)

    An important question in systems biology is what role the underlying molecular mechanisms play in disease progression. The relationship between chronic pancreatitis and pancreatic cancer needs further exploration in a system view. We constructed the disease network based on gene expression data and protein-protein interaction. We proposed an approach to discover the underlying core network and molecular factors in the progression of pancreatic diseases, which contain stages of chronic pancreatitis and pancreatic cancer. The chronic pancreatitis and pancreatic cancer core network and key factors were revealed and then verified by gene set enrichment analysis of pathways and diseases. The key factors provide the microenvironment for tumor initiation and the change of gene expression level of key factors bridge chronic pancreatitis and pancreatic cancer. Some new candidate genes need further verification by experiments. Transcriptome profiling-based network analysis reveals the importance of chronic pancreatitis genes and pathways in pancreatic cancer development on a system level by computational method and they can be therapeutic targets.

    The usefulness of dynamic MRI study using contrast media is studied on pancreatic tumors. This method was useful in detecting small lesion of pancreatic tumor, however, T1-weighted SE method was more useful in detecting swelling lesions or diagnosing degree of tumors. Although endocrine tumors are depicted by contrast media, careful attention is needed since there are some hypovascular cases. T2-weighted image is commonly performed to detect the morphology of cystic content and the correlation between the pancreas and bile duct in cystic tumors, however, dynamic study was more useful in proving vascularity of serous cystadenoma and differentiating malignant or benign mucous cystic tumors by depicting intracystic torous components. In performing MR imaging on pancreatic diseases, it is necessary to select appropriate imaging procedure, and dynamic study should be included and used in a rational manner. (S.Y.)

    -dependent manner. But perhaps equally importantly, GLP-1’s glucose lowering effects are attributable to a strong inhibition of glucagon secretion, and, thereby, a reduction of hepatic glucose output. The effects of GLP-1 on insulin secretion are mediated by binding of the hormone to the receptor (GLP-1r......) on the pancreatic β-cell, which increases intracellular cAMP levels and sets in motion a plethora of events that lead to secretion. In contrast, the inhibitory effect of GLP-1 on the α-cell may be indirect, involving paracrine intra-islet regulation by somatostatin and possibly also insulin, although GLP-1 also...... inhibits glucagon secretion in patients with type 1 diabetes mellitus. Besides these acute effects on the endocrine pancreas, GLP-1 also appears to have a positive effect on β-cell mass.

    The aim of this study was to analyze the gallbladder motor function in chronic pancreatitis (C) patients. Gallbladder emptying was evaluated in 11 patients, without and with addition of pancreatic extract and in ten controls. The results were compared and analyzed statistically. The ejection fraction (E F) of the gallbladder (GB) at 30, 45 and 60 minutes were calculated by using Tc-9 9 m DISIDA scintigraphy. The E F of GB at 60 minutes was significantly higher in the controls when compared to patients, although the results between patients were similar without and with addition of pancreatic extract. The results suggest that the delay in the GB emptying does not depend on the eventual alteration in the intestinal phase of the vesicular stimulation, but it probably results from a mechanic factor, which depends on the chronic pathological process located in the head of the pancreas.

    Percutaneous interventional therapy plays an important role in treating complications of acute and chronic pancreatitis. With the development of cross-sectional imaging and advanced interventional techniques, percutaneous drainage has become the preferred treatment for pancreatic fluid collections such as acute collections, pseudocysts and abscesses. Abscess and pancreatic hemorrhage are the most life threatening complications of pancreatitis. Massive hemorrhage is rare but frequently lethal. As a rule, bleeding complications of pancreatitis require prompt diagnosis and an aggressive surgical approach. In unstable patients with a severely bleeding pseudoaneurysm, hemostasis can be obtained by occlusion with mechanical devices.

    In 1998, Lankisch and Banks reported that the prevalence of chronic pancreatitis appeared to be in the range of 3-10 per 100,000 people in many parts of the world [1]. They also emphasized that the most important medical problems associated with the disease included abdominal pain, steatorrhea, diabetes mellitus and the possibility that chronic pancreatitis may be considered a premalignant condition [2, 3]. In 2002, in a well-written review, Banks pointed out that the two important forms were...

    Purpose: To clarify if the portal venous phase is helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis. Materials and methods: MDCT and MRI of groove pancreatic carcinomas (n = 7) and groove pancreatitis (n = 15) were retrospectively reviewed by two radiologists independently. The signal intensity on T2-weighted images was subjectively assessed. The presence or absence of common bile duct (CBD) and main pancreatic duct (MPD) strictures, calcifications, and cystic lesions was evaluated. Additionally, the appearance of groove pancreatic carcinoma and that of groove pancreatitis in the portal venous phase on dynamic MDCT and MRI were compared. Results: There were no significant differences in the signal intensity on T2-weighted images and in the presence or absence of CBD and MPD strictures, calcifications, and cystic lesions between groove pancreatic carcinomas and groove pancreatitis. However, patchy focal enhancement in the portal venous phase was more commonly observed in groove pancreatitis than groove pancreatic carcinoma (Reviewers 1 and 2: 14/15 [93.3%] vs. 1/7 [14.3%], P < 0.0001). In addition, peripheral enhancement was only seen in groove pancreatic carcinomas (Reviewer 1: 4/7 [57.1%] vs. 0/15 [0%], P < 0.005, and Reviewer 2: 3/7 [42.9%] vs. 0/15 [0%], P < 0.05). Conclusion: The portal venous phase may be helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis.

    The purpose of this study was to characterize the incidence, clinical features, and prognosis of acute pancreatitis in cats with hepatic lipidosis. Of 13 cats histologically diagnosed with hepatic lipidosis between July 1988, and November 1989, 5(38%) were also histologically diagnosed with acute pancreatitis. In cats with hepatic lipidosis alone, the signalment, history, physical examination, and clinicopathologic findings were generally indistinguishable from those of cats with concurrent acute pancreatitis except that cats with acute pancreatitis were more likely to be cachectic and to have coagulation abnormalities. Hepatomegaly was seen on abdominal radiographs in both groups. Of the 5 cats with concurrent acute pancreatitis, abdominal ultrasonography detected 1 cat with a hypoechoic pancreas and 5 with peritoneal effusion; those abnormalities were not seen in cats without concurrent acute pancreatitis. Cats with concurrent acute pancreatitis had only a 20% recovery rate, compared with a 50% recovery rate in cats with hepatic lipidosis alone. We conclude that cats with hepatic lipidosis should be rigorously evaluated for concurrent acute pancreatitis because of 1) the rate of disease coincidence, 2) the inability of signalment, history, physical examination, and clinicopathologic findings to adequately distinguish between hepatic lipidosis and acute pancreatitis, 3) the worse prognosis associated with concurrent acute pancreatitis, and 4) the opposing nutritional strategies for hepatic lipidosis and acute pancreatitis.

    Purpose of review In this article, we review important advances in our understanding of the mechanisms of pancreatitis. Recent Findings The relative contribution of intra-pancreatic trypsinogen activation and NFκB activation, the two major early independent cellular events in the etiology of pancreatitis, have been investigated using novel genetic models. Trypsinogen activation has traditionally held the spotlight for many decades as it is believed to be the central pathogenic event of pancreatitis However, recent experimental evidence points to the role of trypsin activation in early acinar cell damage but not in the inflammatory response of acute pancreatitis through NFκB activation. Further, chronic pancreatitis in the caerulein model develops independently of typsinogen activation. Sustained activation of the NFκB pathway, but not persistent intra-acinar expression of active trypsin, was shown to result in chronic pancreatitis. Calcineurin-NFAT signaling was shown to mediate downstream effects of pathologic rise in intracellular calcium. IL-6 was identified as a key cytokine mediating pancreatitis-associated lung injury. Summary Recent advances challenge the long-believed trypsin-centered understanding of pancreatitis. It is becoming increasingly clear that activation of intense inflammatory signaling mechanisms in acinar cells is crucial to the pathogenesis of pancreatitis, which may explain the strong systemic inflammatory response in pancreatitis.

    2017-10-01

    Pancreatic cancer, adenocarcinoma, generally rapidly progresses, and if a metastatic lesion is detected, chemotherapy is applied even in solitary metastasis. However, surgical resection for solitary metastasis have been reported to achieve long survival in some pancreatic cancer patients. In a prospective study of surgery for hepatic and lymph node oligometastasis of pancreatic cancer, long survival of 5 years or more was reported around 10%. Furthermore, longer survival and fewer rerecurrence were achieved with surgery in lung metastasis than in liver metastasis and loco-regional recurrence. Although there has been no establishment of concept or no consensus of treatment strategy for oligometastasis in pancreatic cancer, some patients with pancreatic cancer have long disease-free survival by surgery for oligometastasis. A population of pancreatic cancer patients who have benefits of surgery for oligometastasis should be identified, and it is necessary to establish treatments for oligometastasis as standard treatments in pancreatic cancer.

  2. Imaging in the diagnosis of chronic pancreatitis

    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.

    Tropical chronic pancreatitis is a form of idiopathic chronic pancreatitis that has not previously been described in Spain. Typically it is related to dietary factors and malnutrition, although genetic factors may also play a significant role in the development of the disease. We report a case of chronic tropical pancreatitis in a 27-year-old woman from the Dominican Republic domiciled in Spain since 1992. The patient was admitted to our hospital for acute pancreatitis that fulfilled the diagnostic criteria (clinical and radiological) for chronic tropical pancreatitis. This case has led us to review this uncommon entity. Because of the increasing number of immigrants from tropical countries, chronic tropical pancreatitis will probably need to be taken into account in the differential diagnosis of chronic pancreatitis in our patients.

    Andrographis paniculata (Burm. f.) Nees is a plant that originates from India and grows widely to Southeast which used for several purposes mainly as treatment of diabetes mellitus so the aim of this study was evaluate andrographolide for its pancreatic effect in neonatal streptozotocin (STZ)-induced diabetic rats, a model of type 2 diabetic rats. Diabetic condition was induced with an intraperitoneal injection of 90 mg kg(-1) streptozotocin in two-day-old rats. After three months, the neonatal STZ-induced diabetic rats were treated with andrographolide or andrographolide-enriched extract of A. paniculata (AEEAP) for 8 consecutive days. Pancreatic effect was evaluated by estimating mainly the preprandial and postprandial blood glucose levels and other parameters such as morphology of pancreatic islet, beta cells density and morphology and immunohistochemically pancreatic insulin. Andrographolide significantly (p < 0.05) decreased the levels of blood glucose and improved diabetic rat islet and beta cells. However, AEEAP exhibited moderate hypoglycaemic effects on the blood glucose levels. Moderate changes in beta cells were observed after AEEAP treatment. They could restore decreasing of pancreatic insulin contents. Based on these results andrographolide and AEEAP exhibited pancreatic actions in neonatal STZ-induced diabetic rats. The activity of andrographolide was more effective than this of AEEAP.

    Chronic pancreatitis is a putative risk factor for pancreatic cancer. The aim of this study was to examine the magnitude and temporality of this association. We searched MEDLINE and EMBASE for observational studies investigating the association between chronic pancreatitis and pancreatic cancer. We computed overall effect estimates (EEs) with associated 95% confidence intervals (CIs) using a random-effects meta-analytic model. The EEs were stratified by length of follow-up from chronic pancreatitis diagnosis to pancreatic cancer (lag period). Robustness of the results was examined in sensitivity analyses. We identified 13 eligible studies. Pooled EEs for pancreatic cancer in patients with chronic pancreatitis were 16.16 (95% CI: 12.59-20.73) for patients diagnosed with pancreatic cancer within 2 years from their chronic pancreatitis diagnosis. The risk of pancreatic cancer in patients with chronic pancreatitis decreased when the lag period was increased to 5 years (EE: 7.90; 95% CI: 4.26-14.66) or a minimum of 9 years (EE: 3.53; 95% CI: 1.69-7.38). In conclusion, chronic pancreatitis increases the risk of pancreatic cancer, but the association diminishes with long-term follow-up. Five years after diagnosis, chronic pancreatitis patients have a nearly eight-fold increased risk of pancreatic cancer. We suggest that common practice on inducing a 2-year lag period in these studies may not be sufficient. We also recommend a close follow-up in the first years following a diagnosis of chronic pancreatitis to avoid overlooking a pancreatic cancer.

    X-ray diagnosis of the pancreatic gland calculous damage as well as chronic pancreatitis have been studied in 23 patients. A methodologic approach to examination of this group of patients was defined. Posteroanterior radiography has been shown to be of decisive importance in diagnosis of the calcified pancreatic gland. Duodenography and choleduodenography both considerably promote recognition of chronic pancreatitis. The radiologic method also allows one to reveal a series of complications: the common bile duct compression, duodenal stenosis, pancreatic tumor in the presence of chronic pancreatitis, malabsorption syndrome

    Most people with cystic fibrosis (80% to 90%) need pancreatic enzyme replacement therapy to prevent malnutrition. Enzyme preparations need to be taken whenever food is taken, and the dose needs to be adjusted according to the food consumed. A systematic review on the efficacy and safety of pancreatic enzyme replacement therapy is needed to guide clinical practice, as there is variability between centres with respect to assessment of pancreatic function, time of commencing treatment, dose and choice of supplements. This is an updated version of a published review. To evaluate the efficacy and safety of pancreatic enzyme replacement therapy in children and adults with cystic fibrosis and to compare the efficacy and safety of different formulations of this therapy and their appropriateness in different age groups. Also, to compare the effects of pancreatic enzyme replacement therapy in cystic fibrosis according to different diagnostic subgroups (e.g. different ages at introduction of therapy and different categories of pancreatic function). We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings. Most recent search: 15 July 2016.We also searched an ongoing trials website and the websites of the pharmaceutical companies who manufacture pancreatic enzyme replacements for any additional trials. Most recent search: 22 July 2016. Randomised and quasi-randomised controlled trials in people of any age, with cystic fibrosis and receiving pancreatic enzyme replacement therapy, at any dosage and in any formulation, for a period of not less than four weeks, compared to placebo or other pancreatic enzyme replacement therapy preparations. Two authors independently assessed trials and extracted outcome data. They also assessed the risk of bias of the trials included in the review. One

    Pancreatic polypeptide (PP) and peptide YY (PYY) are inhibitors of pancreatic exocrine secretion in vivo but not in vitro, which suggests intermediate mechanisms of action. To examine the role of pancreatic blood flow in these inhibitory effects, xenon-133 gas clearance was used to measure pancreatic blood flow while simultaneously measuring pancreatic exocrine secretion. PP or PYY (400 pmol/kg/h) was administered during the intermediate hour of a 3-h secretin (125 ng/kg/h)/cholecystokinin octapeptide (CCK-8) (50 ng/kg/h) infusion. Exocrine secretion and pancreatic blood flow during the PP or PYY hours were compared with that observed in the first and third hours of the secretin/CCK-8 infusion. PP and PYY significantly inhibited secretin/CCK-8-induced pancreatic exocrine secretion. In addition, PYY (but not PP) significantly reduced pancreatic blood flow during secretin/CCK-8 stimulation. Nevertheless, there was no correlation between pancreatic blood flow and bicarbonate or protein outputs. It is concluded that changes in pancreatic blood flow do not mediate the inhibitory effects of PP or PYY on the exocrine pancreas

    Full Text Available The dire prognosis of pancreatic cancer has not markedly improved during past decades. The present study was carried out to explore the effect of Qingyihuaji formula (QYHJ on inhibiting pancreatic cancer and prolonging survival in related Notch signaling pathway. Proliferation of pancreatic cancer cells (SW1990 and PANC-1 was detected by MTT assay at 24, 48, and 72 h with exposure to various concentrations (0.08–50 mg/mL of QYHJ water extract. Pancreatic tumor models of nude mice were divided into three groups randomly (control, QYHJ, and gemcitabine. mRNA and protein expression of Notch target genes (Hes-1, Hey-1, Hey-2, and Hey-L in dissected tumor tissue were detected. Results showed that proliferation of SW1990 cells and PANC-1 cells was inhibited by QYHJ water extract in a dose-dependent and time-dependent manner. QYHJ effectively inhibited tumor growth and prolonged survival time in nude mice. Expression of both Hes-1 and Hey-1 was decreased significantly in QYHJ group, suggesting that Hes-1 and Hey-1 in Notch signaling pathway might be potential targets for QYHJ treatment. This research could help explain the clinical effectiveness of QYHJ and may provide advanced pancreatic cancer patients with a new therapeutic option.

    Abnormal pancreatic function tests have been reported to precede the imaging findings of chronic pancreatitis. Magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP) is increasingly accepted as the primary imaging modality for the detection of structural changes of early mild chronic pancreatitis. The aim of this study was to evaluate MRI/MRCP findings in patients with symptoms consistent with chronic pancreatitis who have normal Secretin Endoscopic Pancreatic Function test. A retrospective study of 32 patients referred for evaluation of chronic abdominal pain consistent with chronic pancreatitis and reported normal standard abdominal imaging (ultrasound, computed tomography, or MRI). All patients underwent Secretin Endoscopic Pancreatic Function testing and pancreatic MRI/MRCP at our institution. We reviewed the MRI/MRCP images in patients who had normal Secretin Endoscopic Pancreatic Function testing. MRI/MRCP images were assessed for pancreatic duct morphology, gland size, parenchymal signal and morphology, and arterial contrast enhancement. Of the 32 patients, 23 had normal Secretin Endoscopic Pancreatic Function testing, and 8 of them had mild to marked spectrum of abnormal MRI/MRCP findings that were predominantly focal. Frequencies of the findings were as follows: pancreatic duct stricture (n=3), pancreatic duct dilatation (n=3), side branch ectasia (n=4), atrophy (n=5), decreased arterial enhancement (n=5), decreased parenchymal signal (n=1), and cavity formation (n=1). The remaining15 patients had normal pancreatic structure on MRI/MRCP. Normal pancreatic function testing cannot exclude abnormal MRI/MRCP especially focal findings of chronic pancreatitis. Further studies needed to verify significance of these findings and establish MRI/MRCP imaging criteria for the diagnosis of chronic pancreatitis.

    Circumportal pancreas is a rare congenital pancreatic anomaly with encasement of the portal vein and/or the superior mesenteric vein by pancreatic tissue. It is often overlooked on cross-sectional imaging studies and can be encountered during pancreatic surgery. Pancreatic head resection with circumportal pancreas is technically difficult and bears an increased risk of postoperative pancreatic fistula. A retrospective chart review of our data base for all patients who had undergone pancreatic head resection between 2004 and 2015 was performed. We identified six patients out of 1102 patients who had undergone pancreatic head surgery in the study period. CT-scan and MRI were never able to identify circumportal pancreas prior to surgery. The right hepatic an artery derived from the superior mesenteric artery in four cases (67%). Additional resection of the pancreatic body was always performed. Postoperative course was uneventful in all cases without occurrence of pancreatic fistula. Circumportal pancreas is a rare entity every pancreatic surgeon should be aware of. It is difficult to identify on cross-sectional imaging studies. A right hepatic artery arising from the superior mesenteric artery should raise suspicion of circumportal pancreas. Additional pancreatic tissue resection should be performed during pancreatic head resections to avoid pancreatic fistula.

    2011-01-01

    The diagnosis of traumatic pancreatic injury in the acute stage is difficult to establish blood tests and abdominal findings alone. Moreover, to determine treatment strategies, it is important not only that a pancreatic injury is diagnosed but also whether a pancreatic ductal injury can be found. At our center, to diagnose isolated pancreatic injuries, we actively perform endoscopic retrograde pancreatography (ERP) in addition to abdominal CT at the time of admission. For cases with complications such as abdominal and other organ injuries, we perform a laparotomy to ascertain whether a pancreatic duct injury is present. In regard to treatment options, for grade III injuries to the pancreatic body and tail, we basically choose distal pancreatectomy, but we also consider the Bracy method depending on the case. As for grade III injuries to the pancreatic head, we primarily choose pancreaticoduodenectomy, but also apply drainage if the situation calls for it. However, pancreatic injuries are often complicated by injuries of other regions of the body. Thus, diagnosis and treatment of pancreatic injury should be based on a comprehensive decision regarding early prioritization of treatment, taking hemodynamics into consideration after admission, and how to minimize complications such as anastomotic leak and pancreatic fistulas.

    2015-01-01

    Pancreatic cancer is one of the most lethal malignancies. Significant progresses have been made in understanding of pancreatic cancer pathogenesis, including appreciation of precursor lesions or premalignant pancreatic intraepithelial neoplasia (PanINs), description of sequential transformation from normal pancreatic tissue to invasive pancreatic cancer and identification of major genetic and epigenetic events and the biological impact of those events on malignant behavior. However, the currently used therapeutic strategies targeting tumor epithelial cells, which are potent in cell culture and animal models, have not been successful in the clinic. Presumably, therapeutic resistance of pancreatic cancer is at least in part due to its drastic desmoplasis, which is a defining hallmark for and circumstantially contributes to pancreatic cancer development and progression. Improved understanding of the dynamic interaction between cancer cells and the stroma is important to better understanding pancreatic cancer biology and to designing effective intervention strategies. This review focuses on the origination, evolution and disruption of stromal molecular and cellular components in pancreatic cancer, and their biological effects on pancreatic cancer pathogenesis.

    Pancreatic trauma is associated with high morbidity and mortality. Diagnosis is often difficult and surgery poses a formidable challenge. Data from 17 patients of pancreatic trauma gathered from a prospectively maintained database were analysed and the following parameters were considered: mode of injury, diagnostic modalities, associated injury, grade of pancreatic trauma and management. Pancreatic trauma was graded from I through IV, as per Modified Lucas Classification. The median age was 39 years (range 19-61). The aetiology of pancreatic trauma was blunt abdominal trauma in 14 patients and penetrating injury in 3. Associated bowel injury was present in 4 cases (3 penetrating injury and 1 blunt trauma) and 1 case had associated vascular injury. 5 patients had grade I, 3 had grade II, 7 had grade III and 2 had grade IV pancreatic trauma. Contrast enhanced computed tomography scan was used to diagnose pancreatic trauma in all patients with blunt abdominal injury. Immediate diagnosis could be reached in only 4 (28.5%) patients. 7 patients responded to conservative treatment. Of the 10 patients who underwent surgery, 6 required it for the pancreas and the duodenum. (distal pancreatectomy with splenectomy-3, pylorus preserving pancreatoduodenectomy-1, debridement with external drainage-1, associated injuries-duodenum-1). Pancreatic fistula, recurrent pancreatitis and pseudocyst formation were seen in 3 (17.05%), 2 (11.7%) and 1 (5.4%) patient respectively. Death occurred in 4 cases (23.5%), 2 each in grades III and IV pancreatic trauma. Contrast enhanced computed tomography scan is a useful modality for diagnosing, grading and following up patients with pancreatic trauma. Although a majority of cases with pancreatic trauma respond to conservative treatment, patients with penetrating trauma, and associated bowel injury and higher grade pancreatic trauma require surgical intervention and are also associated with higher morbidity and mortality.

    Full Text Available Objective: To analyze the assessment value of the quantitative indexes of pancreatic CT perfusion scanning for malignant degree of pancreatic cancer. Methods: A total of 58 patients with space-occupying pancreatic lesions were divided into 20 patients with pancreatic cancer and 38 patients with benign pancreatic lesions after pancreatic CT perfusion. Patients with pancreatic cancer received palliative surgery, and the cancer tissue and para-carcinoma tissue specimens were collected during operation. The differences in pancreatic CT perfusion scanning parameter values and serum tumor marker levels were compared between patients with pancreatic cancer and patients with benign pancreatic lesions, mRNA expression levels of malignant molecules in pancreatic cancer tissue and para-carcinoma tissue were further determined, and the correlation between pancreatic CT perfusion scanning parameter values and malignant degree of pancreatic cancer was analyzed. Results: CT perfusion scanning BF, BV and Per values of patients with pancreatic cancer were lower than those of patients with benign pancreatic lesions; serum CA19-9, CEA, CA125 and CA242 levels were higher than those of patients with benign pancreatic lesions (P<0.05; mRNA expression levels of Bcl-2, Bcl-xL and survivin in pancreatic cancer tissue samples were higher than those in paracarcinoma tissue samples, and mRNA expression levels of P53 and Bax were lower than those in para-carcinoma tissue samples (P<0.05; CT perfusion scanning parameters BF, BV and Per values of patients with pancreatic cancer were negatively correlated with CA19-9, CEA, CA125 and CA242 levels in serum as well as mRNA expression levels of Bcl-2, Bcl-xL and survivin in pancreatic cancer tissue, and positively correlated with mRNA expression levels of P53 and Bax in pancreatic cancer tissue (P<0.05. Conclusions: Pancreatic CT perfusion scanning is a reliable way to judge the malignant degree of pancreatic cancer and plays a

    Discriminating between autoimmune pancreatitis (AIP), chronic pancreatitis (CP), and pancreatic ductal adenocarcinoma (PDAC) can be challenging. In this retrospective study, levels of serum and tissue cytokines were analyzed as part of the clinical strategy for the preoperative differentiation between AIP and PDAC. The identification of differential cytokine profiles may help to prevent unnecessary surgical resection and allow optimal treatment of these pathologies. To compare the cytokine profiles of AIP, CP, and PDAC patients, serum and pancreatic tissue homogenates were subjected to multiplex analysis of 17 inflammatory mediators. In total, serum from 73 patients, composed of 29 AIP (14 AIP-1 and 15 AIP-2), 17 CP, and 27 PDAC, and pancreatic tissue from 36 patients, including 12 AIP (six AIP-1 and six AIP-2), 12 CP, and 12 PDAC, were analyzed. Comparing AIP and PDAC patients' serum, significantly higher concentrations were found in AIP for interleukins IL-1β, IL-7, IL-13, and granulocyte colony-stimulating factor (G-CSF). G-CSF also allowed discrimination of AIP from CP. Furthermore, once AIP was divided into subtypes, significantly higher serum levels for IL-7 and G-CSF were measured in both subtypes of AIP and in AIP-2 for IL-1β when compared to PDAC. G-CSF and TNF-α were also significantly differentially expressed in tissue homogenates between AIP-2 and PDAC. The cytokines IL-1β, IL-7, and G-CSF can be routinely measured in patients' serum, providing an elegant and non-invasive approach for differential diagnosis. G-CSF is a good candidate to supplement the currently known serum markers in predictive tests for AIP and represents a basis for a combined blood test to differentiate AIP and particularly AIP-2 from PDAC, enhancing the possibility of appropriate treatment.

    The Frey procedure has become the standard operative treatment in chronic painful pancreatitis. Biliary diversion could be combined when associated with common bile duct obstruction. The aim of the present study was to evaluate the impact of the type of biliary diversion combined with the Frey procedure on late morbidity. The data from consecutive patients undergoing the Frey procedure and having a minimum follow-up of 2 years were extracted from a maintained prospective database. The mean endpoint was the rate of secondary biliary stricture after the Frey procedure combined with biliary diversion (bilioenteric anastomosis or common bile duct reinsertion in the resection cavity). Between 2006 and 2013, 55 consecutive patients underwent the Frey procedure. Twenty-nine patients had common bile duct obstruction (52.7%). The technique of biliary diversion resulted in bilioenteric anastomosis in 19 patients (65.5%) and common bile duct reinsertion in 10 patients (34.5%). Preoperative characteristics and early surgical outcomes were comparable. Pain control was similar. There was significantly more secondary biliary stricture after common bile duct reinsertion than after bilioenteric anastomosis (60% vs 11%, P = .008). Combined bilioenteric anastomosis during the Frey procedure is an efficient technique for treating common bile duct obstruction that complicates chronic painful pancreatitis. Bilioenteric anastomosis was associated with less secondary biliary stricture than common bile duct reinsertion in the pancreatic resection cavity. Copyright © 2016 Elsevier Inc.

    Full Text Available Acute biliary pancreatitis is one of the major causes of acute pancreatitis.Gallstones, biliary sludge and microlithiasis, especially in pancreatitis without detectable reason, can be the cause of acute pancreatitis. Acute biliary pancreatitis has many controversions in the literature, and its classification and guidelines are being updated very frequently. Atlanta classifications which determine the definitions and guidelines about acute pancreatitis were renewed and published in 2013. It has various clinical aspects, ranging from a mild form which is easily treated, to a severe form that causes complications leading to mortality. The pathogenesis of this disease has not been fully elucidated and several theories have been suggested. New scoring systems and laboratory methods such as proteomics have been suggested for both diagnosis and to predict disease severity, and research on these topics is still in progress. Novel therapeutic approaches with technological developments such as ERCP, ES, MRCP, and EUS are also suggested.

    Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis

    Chronic pancreatitis has been considered over the past years as a single disease, alcohol-induced and different from acute pancreatitis, in terms of etiology and prognosis. Actually, the introduction of a new concept of chronic pancreatitis, now considered as a fibroinflammatory process caused by multiple factors (toxic-metabolic, genetic, immunologic, obstructive), allow to better understand the pathogenesis of this complex disease. Furthermore, the discover of peculiar forms of chronic pancreatitis (autoimmune, paraduodenal, associated to gene mutations), different in term of clinical aspects, findings at imaging, prognosis and therapy, radically changed the concept of the disease. In this brief review, we described the impact of this new concept in the comprehension of pathogenesis, in the definition of peculiar forms of chronic pancreatitis, and in the clinical and therapeutic approach of chronic pancreatitis.

    Purpose: Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by a variety of extra-pancreatic involvements which are frequently misdiagnosed as lesions of corresponding organs. The purpose of this study was to clarify the diagnostic imaging features of extra-pancreatic lesions associated with autoimmune pancreatitis. Materials and methods: We retrospectively analyzed diagnostic images of 90 patients with autoimmune pancreatitis who underwent computer-assisted tomography, magnetic resonance imaging, and/or gallium-67 scintigraphy before steroid therapy was initiated. Results: AIP was frequently (92.2%) accompanied by a variety of extra-pancreatic lesions, including swelling of lachrymal and salivary gland lesions (47.5%), lung hilar lymphadenopathy (78.3%), a variety of lung lesions (51.2%), wall thickening of bile ducts (77.8%), peri-pancreatic or para-aortic lymphadenopathy (56.0%), retroperitoneal fibrosis (19.8%), a variety of renal lesions (14.4%), and mass lesions of the ligamentum teres (2.2%). Characteristic findings in CT and MRI included lymphadenopathies of the hilar, peri-pancreatic, and para-aortic regions; wall thickening of the bile duct; and soft tissue masses in the kidney, ureters, aorta, paravertebral region, ligamentum teres, and orbit. Conclusions: Recognition of the diagnostic features in the images of various involved organs will assist in the diagnosis of autoimmune pancreatitis and in differential diagnoses between autoimmune pancreatitis-associated extra-pancreatic lesions and lesions due to other pathologies.

    We report a 50-year-old male with pseudocysts in the pancreatic tail associated with chronic pancreatitis successfully treated by transpapillary cyst drainage. He had previously undergone ultrasonography-guided percutaneous cyst drainage for a pancreatic pseudocyst in our hospital. He was readmitted due to abdominal pain and fever. Computed tomography showed recurrence of a pseudocyst in the pancreatic tail measuring 5 cm in diameter. Since conservative treatment failed, endoscopic retrograde pancreatography was performed. There was communication between the pseudocyst and the main pancreatic duct, and pancreatic duct stenosis proximal to the pseudocyst. First, transpapillary pancreatic duct drainage was performed using a plastic stent, but the pseudocyst did not decrease in size and became infected. After removal of the stent, a pigtail type nasocystic catheter was placed in the pseudocyst via the pancreatic duct. The pseudocyst infection immediately disappeared, and the pseudocyst gradually decreased and disappeared. After removal of the nasocystic catheter, no recurrence was observed. As transpapillary drainage of pancreatic pseudocyst, cyst drainage and pancreatic duct drainage have been reported. In our patient with pseudocyst in the pancreatic tail, duct drainage was ineffective and the pseudocyst was infected, whereas cyst drainage was very effective. We considered that cyst drainage by a nasocystic catheter was the first-line therapy as the transpapillary drainage of the pancreatic pseudocyst.

    Pancreatic ductal obstruction leading to ductal dilation and recurrent pancreatitis is uncommon in children. Treatment is dependent upon etiology but consists of decompression of the pancreatic duct (PD) proximally, if possible, by endoscopic retrograde cholangiopancreatography (ERCP) intervention or surgical decompression with pancreaticojejunal anastomosis. After institutional review board approval, we retrospectively reviewed the records for 2 children who underwent lateral pancreaticojejunostomy for pancreatic ductal dilation. Data, including demographics, diagnostic studies, operative details, complications, outcomes, and follow-up, were analyzed. Case 1 was a 4-year-old female with pancreatic ductal obstruction with multiple episodes of recurrent pancreatitis and failure of ERCP to clear her PD of stones. She underwent a laparoscopic cholecystectomy with a lateral pancreaticojejunostomy (Puestow procedure). She recovered well with no further episodes of pancreatitis and normal pancreatic function 4 years later. Case 2 was a 2-year-old female who developed recurrent pancreatitis and was found to have papillary stenosis and long common bile-PD channel. Despite multiple sphincterotomies, laparoscopic cholecystectomy, and laparoscopic hepaticoduodenostomy, she continued to experience episodes of pancreatitis. She underwent a laparoscopy converted to open lateral pancreaticojejunostomy. Her recovery was also smooth having had no episodes of pancreatitis or hospital admissions for over 2 years following the Puestow. Indication for lateral pancreaticojejunostomy or Puestow procedure is rare in children and even less often performed using laparoscopy. In our small experience, both patients with pancreatic ductal obstruction managed with Puestow's procedure enjoy durable symptom and pain relief in the long term.

  3. Surgical therapy in chronic pancreatitis.

    Chronic pancreatitis (CP) is an inflammatory disease of the pancreas which causes chronic pain, as well as exocrine and endocrine failure in the majority of patients, together producing social and domestic upheaval and a very poor quality of life. At least half of patients will require surgical intervention at some stage in their disease, primarily for the treatment of persistent pain. Available data have now confirmed that surgical intervention may produce superior results to conservative and endoscopic treatment. Comprehensive individual patient assessment is crucial to optimal surgical management, however, in order to determine which morphological disease variant (large duct disease, distal stricture with focal disease, expanded head or small duct/minimal change disease) is present in the individual patient, as a wide and differing range of surgical approaches are possible depending upon the specific abnormality within the gland. This review comprehensively assesses the evidence for these differing approaches to surgical intervention in chronic pancreatitis. Surgical drainage procedures should be limited to a small number of patients with a dilated duct and no pancreatic head mass. Similarly, a small population presenting with a focal stricture and tail only disease may be successfully treated by distal pancreatectomy. Long-term results of both of these procedure types are poor, however. More impressive results have been yielded for the surgical treatment of the expanded head, for which a range of surgical options now exist. Evidence from level I studies and a recent meta-analysis suggests that duodenum-preserving resections offer benefits compared to pancreaticoduodenectomy, though the results of the ongoing, multicentre ChroPac trial are awaited to confirm this. Further data are also needed to determine which of the duodenum-preserving procedures provides optimal results. In relation to small duct/minimal change disease total pancreatectomy represents the only

    2011-10-01

    In this paper, we propose a novel method that combines PubMed knowledge and Electronic Health Records to develop a weighted Bayesian Network Inference (BNI) model for pancreatic cancer prediction. We selected 20 common risk factors associated with pancreatic cancer and used PubMed knowledge to weigh the risk factors. A keyword-based algorithm was developed to extract and classify PubMed abstracts into three categories that represented positive, negative, or neutral associations between each risk factor and pancreatic cancer. Then we designed a weighted BNI model by adding the normalized weights into a conventional BNI model. We used this model to extract the EHR values for patients with or without pancreatic cancer, which then enabled us to calculate the prior probabilities for the 20 risk factors in the BNI. The software iDiagnosis was designed to use this weighted BNI model for predicting pancreatic cancer. In an evaluation using a case-control dataset, the weighted BNI model significantly outperformed the conventional BNI and two other classifiers (k-Nearest Neighbor and Support Vector Machine). We conclude that the weighted BNI using PubMed knowledge and EHR data shows remarkable accuracy improvement over existing representative methods for pancreatic cancer prediction.

  5. Hedgehog signaling and therapeutics in pancreatic cancer.

    LENUS (Irish Health Repository)

    Kelleher, Fergal C

    2012-02-01

    OBJECTIVE: To conduct a systematic review of the role that the hedgehog signaling pathway has in pancreatic cancer tumorigenesis. METHOD: PubMed search (2000-2010) and literature based references. RESULTS: Firstly, in 2009 a genetic analysis of pancreatic cancers found that a core set of 12 cellular signaling pathways including hedgehog were genetically altered in 67-100% of cases. Secondly, in vitro and in vivo studies of treatment with cyclopamine (a naturally occurring antagonist of the hedgehog signaling pathway component; Smoothened) has shown that inhibition of hedgehog can abrogate pancreatic cancer metastasis. Thirdly, experimental evidence has demonstrated that sonic hedgehog (Shh) is correlated with desmoplasia in pancreatic cancer. This is important because targeting the Shh pathway potentially may facilitate chemotherapeutic drug delivery as pancreatic cancers tend to have a dense fibrotic stroma that extrinsically compresses the tumor vasculature leading to a hypoperfusing intratumoral circulation. It is probable that patients with locally advanced pancreatic cancer will derive the greatest benefit from treatment with Smoothened antagonists. Fourthly, it has been found that ligand dependent activation by hedgehog occurs in the tumor stromal microenvironment in pancreatic cancer, a paracrine effect on tumorigenesis. Finally, in pancreatic cancer, cells with the CD44+CD24+ESA+ immunophenotype select a population enriched for cancer initiating stem cells. Shh is increased 46-fold in CD44+CD24+ESA+ cells compared with normal pancreatic epithelial cells. Medications that destruct pancreatic cancer initiating stem cells are a potentially novel strategy in cancer treatment. CONCLUSIONS: Aberrant hedgehog signaling occurs in pancreatic cancer tumorigenesis and therapeutics that target the transmembrane receptor Smoothened abrogate hedgehog signaling and may improve the outcomes of patients with pancreatic cancer.

    In 2015, the Australasian Pancreatic Club (APC) published the Australasian guidelines for the management of pancreatic exocrine insufficiency (http://pancreas.org.au/2016/01/pancreatic-exocrine-insufficiency-guidelines). Pancreatic exocrine insufficiency (PEI) occurs when normal digestion cannot be sustained due to insufficient pancreatic digestive enzyme activity. This may be related to a breakdown, at any point, in the pancreatic digestive chain: pancreatic stimulation; synthesis, release or transportation of pancreatic enzymes; or synchronisation of secretions to mix with ingested food. Main recommendations: The guidelines provide advice on diagnosis and management of PEI, noting the following: A high prevalence of PEI is seen in certain diseases and conditions, such as cystic fibrosis, acute and chronic pancreatitis, pancreatic cancer and pancreatic surgery. The main symptoms of PEI are steatorrhoea or diarrhoea, abdominal pain, bloating and weight loss. These symptoms are non-specific and often go undetected and untreated. PEI diagnosis is predominantly based on clinical findings and the presence of underlying disease. The likelihood of PEI in suspected patients has been categorised into three groups: definite, possible and unlikely. If left untreated, PEI may lead to complications related to fat malabsorption and malnutrition, and have an impact on quality of life. Pancreatic enzyme replacement therapy (PERT) remains the mainstay of PEI treatment with the recommended adult initial enzyme dose being 25 000-40 000 units of lipase per meal, titrating up to a maximum of 75 000-80 000 units of lipase per meal. Adjunct acid-suppressing therapy may be useful when patients still experience symptoms of PEI on high dose PERT. Nutritional management by an experienced dietitian is essential. Changes in management as a result of these guidelines: These are the first guidelines to classify PEI as being definite, possible or unlikely, and provide a diagnostic algorithm to

    Full Text Available Pancreatic ductal adenocarcinoma (PDAC constitutes 90% of pancreatic cancers. PDAC is a complex and devastating disease with only 1%–3% survival rate in five years after the second stage. Treatment of PDAC is complicated due to the tumor microenvironment, changing cell behaviors to the mesenchymal type, altered drug delivery, and drug resistance. Considering that pancreatic cancer shows early invasion and metastasis, critical research is needed to explore different aspects of the disease, such as elaboration of biomarkers, specific signaling pathways, and gene aberration. In this review, we highlight the biomarkers, the fundamental signaling pathways, and their importance in targeted drug delivery for pancreatic cancers.

    Pancreatic ductal adenocarcinoma (PDAC) constitutes 90% of pancreatic cancers. PDAC is a complex and devastating disease with only 1%-3% survival rate in five years after the second stage. Treatment of PDAC is complicated due to the tumor microenvironment, changing cell behaviors to the mesenchymal type, altered drug delivery, and drug resistance. Considering that pancreatic cancer shows early invasion and metastasis, critical research is needed to explore different aspects of the disease, such as elaboration of biomarkers, specific signaling pathways, and gene aberration. In this review, we highlight the biomarkers, the fundamental signaling pathways, and their importance in targeted drug delivery for pancreatic cancers.

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    The incidence of acute pancreatitis (AP) is increasing and it is associated with a major healthcare concern. New insights in the pathophysiology, better imaging techniques, and novel treatment options for complicated AP prompted the update of the 1992 Atlanta Classification. Updated nomenclature for pancreatic collections based on imaging criteria is proposed. Adoption of the newly Revised Classification of Acute Pancreatitis 2012 by radiologists should help standardise reports and facilitate accurate conveyance of relevant findings to referring physicians involved in the care of patients with AP. This review will clarify the nomenclature of pancreatic collections in the setting of AP.

    Pancreatitis is an inflammatory disease of the pancreas characterized by dysregulated activity of digestive enzymes, necrosis, immune infiltration, and pain. Repeated incidence of pancreatitis is an important risk factor for pancreatic cancer. Legumain, a lysosomal cysteine protease, has been linked to inflammatory diseases such as atherosclerosis, stroke, and cancer. Until now, legumain activation has not been studied during pancreatitis. We used a fluorescently quenched activity-based probe to assess legumain activation during caerulein-induced pancreatitis in mice. We detected activated legumain by ex vivo imaging, confocal microscopy, and gel electrophoresis. Compared with healthy controls, legumain activity in the pancreas of caerulein-treated mice was increased in a time-dependent manner. Legumain was localized to CD68+ macrophages and was not active in pancreatic acinar cells. Using a small-molecule inhibitor of legumain, we found that this protease is not essential for the initiation of pancreatitis. However, it may serve as a biomarker of disease, since patients with chronic pancreatitis show strongly increased legumain expression in macrophages. Moreover, the occurrence of legumain-expressing macrophages in regions of acinar-to-ductal metaplasia suggests that this protease may influence reprogramming events that lead to inflammation-induced pancreatic cancer.

    Full Text Available 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.

    Pancreatic duct disruption accompanied by pancreatic trauma is very severe. Endoscopic retrograde pancreatography (ERP) is considered the main diagnostic modality. However, it is invasive and can be associated with significant complications. We diagnosed pancreatic trauma based on only Computed tomography (CT) scan data. We operated based on specific signs of pancreatic injuries on CT scans, such as edema or hematoma of the pancreatic parenchyma, fractures or lacerations of the pancreas, active hemorrhage and, in all cases, there were main pancreatic duct injuries. Certain drainage of the pancreatic juice is necessary for pancreatic duct disruption. The operation method was selected according to the location of the damage. If it is at all possible pancreas preserving surgery should be performed. It is necessary to select the operation according to the patient's age and general condition, the cause of the injury, the range of the injury, and the experience of the surgeon. When the main duct injury was not certain, ERP during the operation was very useful. We report on a method of endoscopically treating a pseudocyst, which has adhered to the stomach, secondary to pancreatic main duct disruption. Transgastric placement of a stent into the pseudocyst is possible in restricted cases. (author)

    Hypertrigliceridemia is the third most common cause of acute pancreatitis. The risk of developing acute pancreatitis is 5% in healthy patients and 4% during pregnancy with triglyceride levels >1,000mg/dl. During pregnancy there are changes in the lipid profile that increase between two and four times triglyceride levels. Its increase in excessive form produces an oxidative environment with injury of the endothelium and appearance of complications such as preeclampsia or pancreatitis. We present the case of a pregnant woman with pancreatitis secondary to hypertriglyceridemia. Copyright © 2017 Sociedad Española de Arteriosclerosis. Publicado por Elsevier España, S.L.U.

    Full Text Available Pancreatic cancer carries a poor prognosis as most patients present with advanced disease and preferred chemotherapy regimens offer only modest effects on survival. Risk factors include smoking, obesity, heavy alcohol, and chronic pancreatitis. Pancreatic cancer has a complex relationship with diabetes, as diabetes can be both a risk factor for pancreatic cancer and a result of pancreatic cancer. Insulin, insulin-like growth factor-1 (IGF-1, and certain hormones play an important role in promoting neoplasia in diabetics. Metformin appears to reduce risk for pancreatic cancer and improve survival in diabetics with pancreatic cancer primarily by decreasing insulin/IGF signaling, disrupting mitochondrial respiration, and inhibiting the mammalian target of rapamycin (mTOR pathway. Other potential anti-tumorigenic effects of metformin include the ability to downregulate specificity protein transcription factors and associated genes, alter microRNAs, decrease cancer stem cell proliferation, and reduce DNA damage and inflammation. Here, we review the most recent knowledge on risk factors and treatment of pancreatic cancer and the relationship between diabetes, pancreatic cancer, and metformin as a potential therapy.

  4. Endoscopic Palliation for Pancreatic Cancer

    Full Text Available Pancreatic cancer is devastating due to its poor prognosis. Patients require a multidisciplinary approach to guide available options, mostly palliative because of advanced disease at presentation. Palliation including relief of biliary obstruction, gastric outlet obstruction, and cancer-related pain has become the focus in patients whose cancer is determined to be unresectable. Endoscopic stenting for biliary obstruction is an option for drainage to avoid the complications including jaundice, pruritus, infection, liver dysfunction and eventually failure. Enteral stents can relieve gastric obstruction and allow patients to resume oral intake. Pain is difficult to treat in cancer patients and endoscopic procedures such as pancreatic stenting and celiac plexus neurolysis can provide relief. The objective of endoscopic palliation is to primarily address symptoms as well improve quality of life.

    Cell replacement therapy could represent an attractive alternative to insulin injections for the treatment of diabetes. However, this approach requires a thorough understanding of the molecular switches controlling the specification of the different pancreatic cell-types in vivo. These are derived from an apparently identical pool of cells originating from the early gut endoderm, which are successively specified towards the pancreatic, endocrine, and hormone-expressing cell lineages. Numerous studies have outlined the crucial roles exerted by transcription factors in promoting the cell destiny, defining the cell identity and maintaining a particular cell fate. This review focuses on the mechanisms regulating the morphogenesis of the pancreas with particular emphasis on recent findings concerning the transcription factor hierarchy orchestrating endocrine cell fate allocation.

  6. Apoptosis: Targets in Pancreatic Cancer

    Directory of Open Access Journals (Sweden)

    Kalthoff Holger

    2003-01-01

    Full Text Available Abstract Pancreatic adenocarcinoma is characterized by poor prognosis, because of late diagnosis and lack of response to chemo- and/or radiation therapies. Resistance to apoptosis mainly causes this insensitivity to conventional therapies. Apoptosis or programmed cell death is a central regulator of tissue homeostasis. Certain genetic disturbances of apoptotic signaling pathways have been found in carcinomas leading to tumor development and progression. In the past few years, the knowledge about the complex pathways of apoptosis has strongly increased and new therapeutic approaches based on this knowledge are being developed. This review will focus on the role of apoptotic proteins contributing to pancreatic cancer development and progression and will demonstrate possible targets to influence this deadly disease.

  7. Surgery of malignant pancreatic tumors

    Loos, M.; Friess, H.; Kleeff, J.

    2009-01-01

    Ductal adenocarcinoma is the most common malignant tumor of the pancreas. Despite great efforts in basic and clinical pancreatic cancer research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection represents the only curative treatment option and 5-year survival rates of 20-25% can be achieved following curative resection and adjuvant chemotherapy. Although pancreatic surgery is considered one of the most technically demanding and challenging procedures, there has been constant progress in surgical techniques and advances in perioperative care with a modern interdisciplinary approach including anesthesiology, oncology, radiology and nursing. This has reduced morbidity and especially mortality rates in high-volume centers. Among extended resection procedures multivisceral and venous resections are technically feasible and should be considered if a complete tumor resection can be achieved. Multimodal regimens have shown promising results, however, only adjuvant chemotherapy is supported by solid evidence from randomized controlled trials. (orig.) [de

    The pathogenic mechanism of pancreatitis is poorly understood. Recent evidence implicates defective autophagy in pancreatitis responses; however, the pathways mediating impaired autophagy in pancreas remain largely unknown. Here, we investigate the role of lysosome associated membrane proteins (LAMPs) in pancreatitis. We analyzed changes in LAMPs in experimental models and human pancreatitis, and the underlying mechanisms: LAMP de-glycosylation and degradation. LAMP cleavage by cathepsin B (CatB) was analyzed by mass spectrometry. We used mice deficient in LAMP-2 to assess its role in pancreatitis. Pancreatic levels of LAMP-1 and LAMP-2 greatly decrease across various pancreatitis models and in human disease. Pancreatitis does not trigger LAMPs' bulk de-glycosylation, but induces their degradation via CatB-mediated cleavage of LAMP molecule close to the boundary between luminal and transmembrane domains. LAMP-2 null mice spontaneously develop pancreatitis that begins with acinar cell vacuolization due to impaired autophagic flux, and progresses to severe pancreas damage characterized by trypsinogen activation, macrophage-driven inflammation, and acinar cell death. LAMP-2 deficiency causes a decrease in pancreatic digestive enzymes content, stimulates the basal and inhibits CCK-induced amylase secretion by acinar cells. The effects of LAMP-2 knockout and acute cerulein pancreatitis overlap, which corroborates the pathogenic role of LAMP decrease in experimental pancreatitis models. The results indicate a critical role for LAMPs, particularly LAMP-2, in maintaining pancreatic acinar cell homeostasis, and provide evidence that defective lysosomal function, resulting in impaired autophagy, leads to pancreatitis. Mice with LAMP-2 deficiency present a novel genetic model of human pancreatitis caused by lysosomal/autophagic dysfunction.

    Full Text Available Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or other organ systems. The severe form of the disease occurs in 10-20% of cases, and usually requires prolonged hospitalization due to a frequent local and systemic complications. Additionally, considerable mortality despite diagnostic and therapeutic advances, makes this disease a serious health problem nowadays. The aim of this study was to conduct a review of randomized controlled trials to determine differences in the efficiency between standard methods of treatment for severe acute pancreatitis and new treatment ways in terms of decreased mortality. Search of the 'Medline' database of original scientific papers and systematic review articles was made, using a combination of the following keywords: acute pancreatitis, treatment, mortality. In total 914 papers were found, published in the last 13 years; 14 of 64 randomized controlled clinical trials met the selection criteria and were eligible for inclusion. From a total of 16 papers, the conservative treatment was related to 11, which includes some of the new treatment methods, while the effects of new methods of treatment have been the subject of research in the four studies. Combined endoscopic and surgical treatment was applied in only one study. The largest sample of 290 patients was included in the study with platelet activation factor antagonist, while the smallest sample of 22 patients was used in the study that compared total parenteral with enteral nutrition. Continuous regional arterial infusion of protease inhibitors in combination with antibiotics, intravenous supplementation of alanyl-glutamine dipeptide and the early, high-volume continuous veno-venous hemofiltration showed the best results in the treatment of patients with severe acute pancreatitis. Also, the use of low molecular weight heparin and enteral nutrition significantly reduced mortality.

    Saw palmetto is a frequently used botanical agent in benign prostatic enlargement (BPH). Although it has been reported to cause cholestatic hepatitis and many medical conditions, Saw palmetto has not been implicated in acute pancreatitis. We report a case of a probable Saw palmetto induced acute hepatitis and pancreatitis. A 55-year-old reformed alcoholic, sober for greater than 15 years, presented with severe non-radiating epigastric pain associated with nausea and vomiting. His only significant comorbidity is BPH for which he intermittently took Saw palmetto for about four years. Physical examination revealed normal vital signs, tender epigastrium without guarding or rebound tenderness. Cullen and Gray Turner signs were negative. Complete blood count and basic metabolic profile were normal. Additional laboratory values include a serum amylase: 2,152 mmol/L, lipase: 39,346 mmol/L, serum triglyceride: 38 mmol/L, AST: 1265, ALT: 1232 and alkaline phosphatase was 185. Abdominal ultrasound and magnetic resonance cholangiography revealed sludge without stones. A hepatic indole diacetic acid scan was negative. Patient responded clinically and biochemically to withdrawal of Saw palmetto. Two similar episodes of improvements followed by recurrence were noted with discontinuations and reinstitution of Saw Palmetto. Simultaneous and sustained response of hepatitis and pancreatitis to Saw palmetto abstinence with reoccurrence on reinstitution strongly favors drug effect. "Natural" medicinal preparations are therefore not necessarily safe and the importance of detailed medication history (including "supplements") cannot be over emphasized.

  11. Pancreatic Expression database: a generic model for the organization, integration and mining of complex cancer datasets

    2007-11-01

    Full Text Available Abstract Background Pancreatic cancer is the 5th leading cause of cancer death in both males and females. In recent years, a wealth of gene and protein expression studies have been published broadening our understanding of pancreatic cancer biology. Due to the explosive growth in publicly available data from multiple different sources it is becoming increasingly difficult for individual researchers to integrate these into their current research programmes. The Pancreatic Expression database, a generic web-based system, is aiming to close this gap by providing the research community with an open access tool, not only to mine currently available pancreatic cancer data sets but also to include their own data in the database. Description Currently, the database holds 32 datasets comprising 7636 gene expression measurements extracted from 20 different published gene or protein expression studies from various pancreatic cancer types, pancreatic precursor lesions (PanINs and chronic pancreatitis. The pancreatic data are stored in a data management system based on the BioMart technology alongside the human genome gene and protein annotations, sequence, homologue, SNP and antibody data. Interrogation of the database can be achieved through both a web-based query interface and through web services using combined criteria from pancreatic (disease stages, regulation, differential expression, expression, platform technology, publication and/or public data (antibodies, genomic region, gene-related accessions, ontology, expression patterns, multi-species comparisons, protein data, SNPs. Thus, our database enables connections between otherwise disparate data sources and allows relatively simple navigation between all data types and annotations. Conclusion The database structure and content provides a powerful and high-speed data-mining tool for cancer research. It can be used for target discovery i.e. of biomarkers from body fluids, identification and analysis

    2016-01-01

    Abstract Few data are present in the literature on the relationship between atorvastatin use and acute pancreatitis. The aim of this study was to explore this issue in Taiwan. Using representative claims data established from the Taiwan National Health Insurance Program, this case–control study consisted of 5810 cases aged 20 to 84 years with a first-time diagnosis of acute pancreatitis during the period 1998 to 2011and 5733 randomly selected controls without acute pancreatitis. Both cases and controls were matched by sex, age, comorbidities, and index year of diagnosing acute pancreatitis. Subjects who at least received 1 prescription for other statins or nonstatin lipid-lowering drugs were excluded from the study. If subjects never had 1 prescription for atorvastatin, they were defined as never use of atorvastatin. Current use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted ≤7 days before the date of diagnosing acute pancreatitis. Late use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted >7 days before the date of diagnosing acute pancreatitis. The odds ratio with 95% confidence interval of acute pancreatitis associated with atorvastatin use was calculated by using the logistic regression analysis. The logistic regression analysis revealed that the odds ratio of acute pancreatitis was 1.67 for subjects with current use of atorvastatin (95% confidence interval 1.18, 2.38), when compared with subjects with never use of atorvastatin. The odds ratio decreased to 1.15 for those with late use of atorvastatin (95% confidence interval 0.87, 1.52), but without statistical significance. Current use of atorvastatin is associated with the diagnosis of acute pancreatitis. Clinically, clinicians should consider the possibility of atorvastatin-associated acute pancreatitis when patients present with a diagnosis of acute pancreatitis without a definite etiology but are taking

    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.

    For patients with chronic pancreatitis and a dilated pancreatic duct, ductal decompression is recommended. We conducted a randomized trial to compare endoscopic and surgical drainage of the pancreatic duct. All symptomatic patients with chronic pancreatitis and a distal obstruction of the pancreatic duct but without an inflammatory mass were eligible for the study. We randomly assigned patients to undergo endoscopic transampullary drainage of the pancreatic duct or operative pancreaticojejunostomy. The primary end point was the average Izbicki pain score during 2 years of follow-up. The secondary end points were pain relief at the end of follow-up, physical and mental health, morbidity, mortality, length of hospital stay, number of procedures undergone, and changes in pancreatic function. Thirty-nine patients underwent randomization: 19 to endoscopic treatment (16 of whom underwent lithotripsy) and 20 to operative pancreaticojejunostomy. During the 24 months of follow-up, patients who underwent surgery, as compared with those who were treated endoscopically, had lower Izbicki pain scores (25 vs. 51, Psurgical drainage (P=0.007). Rates of complications, length of hospital stay, and changes in pancreatic function were similar in the two treatment groups, but patients receiving endoscopic treatment required more procedures than did patients in the surgery group (a median of eight vs. three, PSurgical drainage of the pancreatic duct was more effective than endoscopic treatment in patients with obstruction of the pancreatic duct due to chronic pancreatitis.

    The aim of this prospective study was to assess pancreatic exocrine function in patients recovering from a first attack of acute pancreatitis, and to evaluate its relationship to severity of attack, extent of pancreatic necrosis and severity of pancreatic endocrine insufficiency. Between December 2000 and November 2001, 23 patients were prospectively evaluated. Pancreatic exocrine function was measured by the faecal elastase-1 test and insufficiency was classified as moderately impaired or severely impaired. Pancreatic necrosis was determined by contrast-enhanced CT scan, and its extent was categorised according to Balthazar's classification. The severity of pancreatic endocrine insufficiency was categorised according to insulin dependence. Attacks were classified as mild (n = 16) or severe (n = 7) according to the Atlanta criteria. Pancreatic exocrine insufficiency was significantly more frequent in patients recovering from severe attacks than mild (n = 6, 86% vs. n = 2, 13%; p = 0.002), and in those who developed pancreatic necrosis or pseudocyst than those who did not (6 of 7 patients vs. 2 of 16 patients, and 5 of 5 patients vs. 3 of 18 patients respectively; p = 0.002). The development of exocrine insufficiency correlated strongly with the extent of pancreatic necrosis (r = -0.754, p pancreatic endocrine insufficiency (n = 4, r = -0.453, p = 0.03). Pancreatic exocrine insufficiency is a common occurrence in patients recovering from severe acute pancreatitis, and its severity correlates with the extent of pancreatic necrosis and the severity of concomitant pancreatic endocrine insufficiency.

    Biomarker testing can be helpful to monitor disease progression after resection of pancreatic cancer. This systematic review aims to give an overview of the literature on the diagnostic value of serum tumor markers for the detection of recurrent pancreatic cancer during follow-up. A systematic search was performed to 2 October 2017. All studies reporting on the diagnostic value of postoperatively measured serum biomarkers for the detection of pancreatic cancer recurrence were included. Data on diagnostic accuracy of tumor markers were extracted. Forest plots and pooled values of sensitivity and specificity were calculated. Four articles described test results of CA 19-9. A pooled sensitivity and specificity of respectively 0.73 (95% CI 0.66-0.80) and 0.83 (95% CI 0.73-0.91) were calculated. One article reported on CEA, showing a sensitivity of 50% and specificity of 65%. No other serum tumor markers were discussed for surveillance purposes in the current literature. Although testing of serum CA 19-9 has considerable limitations, CA 19-9 remains the most used serum tumor marker for surveillance after surgical resection of pancreatic cancer. Further studies are needed to assess the role of serum tumor marker testing in the detection of recurrent pancreatic cancer and to optimize surveillance strategies.

    2011-01-01

    Extraction of large pancreatic and common bile duct (CBD) calculi has always challenged the therapeutic endoscopist. Extracorporeal shockwave lithotripsy (ESWL) is an excellent tool for patients with large pancreatic and CBD calculi that are not amenable to routine endotherapy. Pancreatic calculi in the head and body are targeted by ESWL, with an aim to fragment them to ESWL with 5000 shocks being delivered at each session. The use of epidural anesthesia helped in reducing patient movement. This, together with the better focus achieved with newer third-generation lithotripters, prevents collateral tissue damage and minimizes the complications. Complications in our experience with nearly 1300 patients were minimal, and no extension of hospital stay was required. Similar rates of clearance of pancreatic and biliary calculi with minimal adverse effects have been reported from the centers where ESWL is performed regularly. In view of its high efficiency, non-invasive nature and low complication rates, ESWL can be offered as the first-line therapy for selected patients with large pancreatic and CBD calculi.

  4. Animal models for investigating chronic pancreatitis

    Science.gov (United States)

    2011-01-01

    Chronic pancreatitis is defined as a continuous or recurrent inflammatory disease of the pancreas characterized by progressive and irreversible morphological changes. It typically causes pain and permanent impairment of pancreatic function. In chronic pancreatitis areas of focal necrosis are followed by perilobular and intralobular fibrosis of the parenchyma, by stone formation in the pancreatic duct, calcifications in the parenchyma as well as the formation of pseudocysts. Late in the course of the disease a progressive loss of endocrine and exocrine function occurs. Despite advances in understanding the pathogenesis no causal treatment for chronic pancreatitis is presently available. Thus, there is a need for well characterized animal models for further investigations that allow translation to the human situation. This review summarizes existing experimental models and distinguishes them according to the type of pathological stimulus used for induction of pancreatitis. There is a special focus on pancreatic duct ligation, repetitive overstimulation with caerulein and chronic alcohol feeding. Secondly, attention is drawn to genetic models that have recently been generated and which mimic features of chronic pancreatitis in man. Each technique will be supplemented with data on the pathophysiological background of the model and their limitations will be discussed. PMID:22133269

    Thirteen patients with resectable pancreatic carcinoma were examined by computed tomography (CT). Nine had a mass, 2 had dilatation of the main pancreatic duct, 1 appeared to have ductal dilatation, and 1 had no sign of abnormality. Resectable carcinoma was diagnosed retrospectively in 8 cases, based on the following criteria: a mass with a distinct contour, frequently containing a tiny or irregular low-density area and accompanied by dilatation of the caudal portion of the main pancreatic duct without involvement of the large vessels, liver, or lymph nodes. Including unresectable cancer, chronic pancreatitis, and obstructive jaundice from causes other than cancer, the false-positive rate was less than 6%. However, a small cancer without change in pancreatic contour is difficult to detect with CT

    Estrogen, whether therapeutic or physiologic, can cause hypertriglyceridemia. Hypertriglyceridemia-induced pancreatitis is a rare complication. We report 2 women who developed estrogen-associated severe hypertriglyceridemia with pancreatitis. The first patient developed pancreatitis secondary to hypertriglyceridemia associated with in vitro fertilization cycles. Marked reduction in her triglyceride was achieved with dietary restrictions and fibrate. The second patient developed pancreatitis secondary to hypertriglyceridemia during her pregnancies. She was noncompliant with the treatment; therefore, her triglyceride remained high after delivery. In both patients, no hypertriglyceridemia-associated genes mutations were identified, although the second patient had strong polygenic susceptibility to hypertriglyceridemia. Estrogen-induced severe hypertriglyceridemia with pancreatitis can be a life-threatening condition. Screening in high-risk patients is crucial to prevent subsequent complications.

    Full Text Available Thyroid storm is an acute, life-threatening exacerbation and sudden releasing large amounts of thyroid hormone in a short period of time. Nevertheless, critical aggravation of hyperthyroidism typically resulted from concurrent disorder. Synchronous management of thyroid storm along with its precipitant, such as infection is recommended. We described the case of an acute biliary pancreatitis complicated with a thyroid storm. The patient was successfully managed with a quick surgical intervention and further critical care for thyroid storm. Although it is widely believed that pancreatitis is seldom concurrent with thyrotoxicosis, thyroid storm can be precipitated by a variety of factors, including intra-abdominal infections such as acute pancreatitis or perforated peptic ulcer. In conclusion, acute pancreatitis in patients with thyrotoxicosis seems to be extremely rare, but such patients should be managed intensively against underlying thyroid disorders as well as pancreatitis.

    Full Text Available Pancreatic α-amylase inhibitors offer an effective strategy to lower the levels of post prandial hyperglycemia via control of starch breakdown. Eleven Ayurvedic Indian medicinal plants with known hypoglycemic properties were subjected to sequential solvent extraction and tested for α-amylase inhibition, in order to assess and evaluate their inhibitory potential on pancreatic α-amylase. Analysis of 91 extracts, showed that 10 exhibited strong Human Pancreatic Amylase (HPA inhibitory potential. Of these, 6 extracts showed concentration dependent inhibition with IC50 values, namely, cold and hot water extracts from Ficus bengalensis bark (4.4 and 125 μgmL-1, Syzygium cumini seeds (42.1 and 4.1 μgmL-1, isopropanol extracts of Cinnamomum verum leaves (1.0 μgmL-1 and Curcuma longa rhizome (0.16 μgmL-1. The other 4 extracts exhibited concentration independent inhibition, namely, methanol extract of Bixa orellana leaves (49 μgmL-1, isopropanol extract from Murraya koenigii leaves (127 μgmL-1, acetone extracts from C. longa rhizome (7.4 μgmL-1 and Tribulus terrestris seeds (511 μgmL-1. Thus, the probable mechanism of action of the above fractions is due to their inhibitory action on HPA, thereby reducing the rate of starch hydrolysis leading to lowered glucose levels. Phytochemical analysis revealed the presence of alkaloids, proteins, tannins, cardiac glycosides, flavonoids, saponins and steroids as probable inhibitory compounds.

  12. Acute recurrent pancreatitis: Etiopathogenesis, diagnosis and treatment

    2014-01-01

    Acute recurrent pancreatitis (ARP) refers to a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion. Recurrence of pancreatitis generally occurs in a setting of normal morpho-functional gland, however, an established chronic disease may be found either on the occasion of the first episode of pancreatitis or during the follow-up. The aetiology of ARP can be identified in the majority of patients. Most common causes include common bile duct stones or sludge and bile crystals; sphincter of oddi dysfunction; anatomical ductal variants interfering with pancreatic juice outflow; obstruction of the main pancreatic duct or pancreatico-biliary junction; genetic mutations; alcohol consumption. However, despite diagnostic technologies, the aetiology of ARP still remains unknown in up to 30% of cases: in these cases the term “idiopathic” is used. Because occult bile stone disease and sphincter of oddi dysfunction account for the majority of cases, cholecystectomy, and eventually the endoscopic biliary and/or pancreatic sphincterotomy are curative in most of cases. Endoscopic biliary sphincterotomy appeared to be a curative procedure per se in about 80% of patients. Ursodeoxycholic acid oral treatment alone has also been reported effective for treatment of biliary sludge. In uncertain cases toxin botulin injection may help in identifying some sphincter of oddi dysfunction, but this treatment is not widely used. In the last twenty years, pancreatic endotherapy has been proven effective in cases of recurrent pancreatitis depending on pancreatic ductal obstruction, independently from the cause of obstruction, and has been widely used instead of more aggressive approaches.

  13. Update on endoscopic pancreatic function testing

    Hormone-stimulated pancreatic function tests (PFTs) are considered the gold standard for measuring pancreatic exocrine function. PFTs involve the administration of intravenous secretin or cholecystokinin, followed by collection and analysis of pancreatic secretions. Because exocrine function may decline in the earliest phase of pancreatic fibrosis, PFTs are considered accurate for diagnosing chronic pancreatitis. Unfortunately, these potentially valuable tests are infrequently performed except at specialized centers, because they are time consuming and complicated. To overcome these limitations, endoscopic PFT methods have been developed which include aspiration of pancreatic secretions through the suction channel of the endoscope. The secretin endoscopic pancreatic function test (ePFT) involves collection of duodenal aspirates at 15, 30, 45 and 60 min after secretin stimulation. A bicarbonate concentration greater than 80 mmol/L in any of the samples is considered a normal result. The secretin ePFT has demonstrated good sensitivity and specificity compared with various reference standards, including the "Dreiling tube" secretin PFT, endoscopic ultrasound, and surgical histology. Furthermore, a standard autoanalyzer can be used for bicarbonate analysis, which allows the secretin ePFT to be performed at any hospital. The secretin ePFT may complement imaging tests like endoscopic ultrasound (EUS) in the diagnosis of early chronic pancreatitis.This paper will review the literature validating the use of ePFT in the diagnosis of exocrine insufficiency and chronic pancreatitis. Newer developments will also be discussed, including the feasibility of combined EUS/ePFT, the use of cholecystokinin alone or in combination with secretin, and the discovery of new protein and lipid pancreatic juice biomarkers which may complement traditionalfluid analysis.

    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.

  17. β-Cell regeneration through the transdifferentiation of pancreatic cells: Pancreatic progenitor cells in the pancreas.

    Science.gov (United States)

    Kim, Hyo-Sup; Lee, Moon-Kyu

    2016-05-01

    Pancreatic progenitor cell research has been in the spotlight, as these cells have the potential to replace pancreatic β-cells for the treatment of type 1 and 2 diabetic patients with the absence or reduction of pancreatic β-cells. During the past few decades, the successful treatment of diabetes through transplantation of the whole pancreas or isolated islets has nearly been achieved. However, novel sources of pancreatic islets or insulin-producing cells are required to provide sufficient amounts of donor tissues. To overcome this limitation, the use of pancreatic progenitor cells is gaining more attention. In particular, pancreatic exocrine cells, such as duct epithelial cells and acinar cells, are attractive candidates for β-cell regeneration because of their differentiation potential and pancreatic lineage characteristics. It has been assumed that β-cell neogenesis from pancreatic progenitor cells could occur in pancreatic ducts in the postnatal stage. Several studies have shown that insulin-producing cells can arise in the duct tissue of the adult pancreas. Acinar cells also might have the potential to differentiate into insulin-producing cells. The present review summarizes recent progress in research on the transdifferentiation of pancreatic exocrine cells into insulin-producing cells, especially duct and acinar cells.

    Objective: To study the MR cholangiopancreatography (MRCP) characteristics of different pancreatic diseases, and to identify the diagnostic value of MRCP for pancreatic diseases. Methods: One hundred and eleven patients with suspected pancreatic diseases underwent MRCP examination. The MRCP sequences included thick-slice turbo spin echo (TSE) and thin-slice half-Fourier acquisition single shot turbo spin echo (HASTE) sequences. The pancreatic diseases included pancreatic carcinoma (n=46), chronic pancreatitis (n=39), peri-ampullar carcinoma (n=23), and choledocholith (n=3). Results: (1) The abnormal manifestation of pancreatic duct was observed in 37 cases of pancreatic carcinoma, 24 cases of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma. Dilated pancreatic duct with smooth and regular caliber was observed in 33 cases of pancreatic carcinoma, 0 case of chronic pancreatitis, and 12 cases of peri-ampullar carcinoma, and statistical analysis showed significant difference (χ 2 =57.911, P 2 =60.343, P 2 =61.217, P 2 =34.654, P 2 =54.593, P<0.01). Conclusion: Different MRI characteristics were observed in various pancreatic diseases respectively. MRCP can show the subtle differences among the pancreatic diseases, and is very helpful in the diagnosis and differential diagnosis of pancreatic diseases

    Diabetes mellitus is a group of diseases defined by persistent hyperglycaemia. Type 2 diabetes, the most prevalent form, is characterised initially by impaired insulin sensitivity and subsequently by an inadequate compensatory insulin response. Diabetes can also develop as a direct consequence of other diseases, including diseases of the exocrine pancreas. Historically, diabetes due to diseases of the exocrine pancreas was described as pancreatogenic or pancreatogenous diabetes mellitus, but recent literature refers to it as type 3c diabetes. It is important to note that type 3c diabetes is not a single entity; it occurs because of a variety of exocrine pancreatic diseases with varying mechanisms of hyperglycaemia. The most commonly identified causes of type 3c diabetes are chronic pancreatitis, pancreatic ductal adenocarcinoma, haemochromatosis, cystic fibrosis, and previous pancreatic surgery. In this Review, we discuss the epidemiology, pathogenesis, and clinical relevance of type 3c diabetes secondary to chronic pancreatitis and pancreatic ductal adenocarcinoma, and highlight several important knowledge gaps.

    Pancreatectomy, including pancreatoduodenectomy and distal pancreatectomy, often causes postoperative pancreatic exocrine insufficiency (PEI). Our aim was to clarify a relationship between remnant pancreatic volume and postoperative PEI. A total of 227 patients who underwent pancreatoduodenectomy or distal pancreatectomy were enrolled in this study. All patients underwent a (13)C-labeled mixed triglyceride breath test to assess pancreatic exocrine function and abdominal dynamic computed tomography for assessing remnant pancreatic volume after pancreatectomy at a median of 7 months postoperatively. The percent (13)CO2 cumulative dose at 7 hours (% dose (13)C cum 7 h) pancreatectomy were performed in 174 (76.7%) and 53 (23.3%) patients, respectively. Of the 227 patients, 128 (56.3%) developed postoperative PEI. Postoperative % dose (13)C cum 7 h was strongly correlated with remnant pancreatic volume (r = .509, P pancreatectomy (P pancreatectomy. Remnant pancreatic volume may predict postoperative PEI in patients who undergo pancreatectomy. Copyright © 2016 Elsevier Inc. All rights reserved.

  3. Role of chymotrypsin C in development and progression of pancreatitis and pancreatic cancer

    Directory of Open Access Journals (Sweden)

    LIU Zejie

    2016-11-01

    Full Text Available Chymotrypsin C (CTRC is a trypsinogen synthesized by pancreatic acinar cells and secreted by pancreatic duct cells and belongs to the family of serine chymotrypsin. The main function of CTRC is to regulate the balance between activation and degradation of trypsin and maintain the structural and functional integrity of the pancreas. CTRC gene mutations can cause abnormal activation of trypsinogen and abnormal degradation of trypsin and then lead to the development of pancreatitis. The downregulation or absence of CTRC expression may be associated with the development and metastasis of pancreatic cancer. This article introduces the structure and biological function of CTRC and its mechanism of action in the development and progression of pancreatitis and pancreatic cancer.

    Solid pseudopapillary pancreatic tumor is a rare tumor affecting young women. Case reports have presented pregnancy outcomes after pancreaticoduodenectomy (Whipple procedure) in pregnancy for this neoplasm. We report a case of a woman who underwent a preconception Whipple procedure for a solid pseudopapillary pancreatic tumor who experienced recurrent pancreatitis confined to pregnancy. A 28-year-old gravida 2 para 1 woman with a history of a Whipple procedure for a solid pseudopapillary pancreatic tumor 2 years prior had three episodes of severe pancreatitis in pregnancy. She was managed conservatively with each episode. She delivered at term and did not have a recurrence in the 8 months since her delivery. Recurrent pancreatitis in pregnancy after a preconception Whipple procedure can be managed conservatively without surgical intervention.

    Hypertriglyceridemia (HTG) is a well established but underestimated cause of acute (AP) and recurrent AP (RAP). The clinical presentation of HTG-induced pancreatitis (HTG pancreatitis) is similar to other causes. Pancreatitis secondary to HTG is typically seen in the presence of one or more secondary factors (uncontrolled diabetes, alcoholism, medications, pregnancy) in a patient with an underlying common genetic abnormality of lipoprotein metabolism (Familial combined hyperlipidemia or Familial HTG). Less commonly, a patient with rare genetic abnormality (Familial chylomicronemic syndrome) with or without an additional secondary factor is encountered. The risk of AP in patients with serum triglycerides >1000 mg/dl and >2000 mg/dl is ∼5% and 10-20% respectively. It is not clear whether HTG pancreatitis is more severe than when it is due to other causes. Clinical management of HTG pancreatitis is similar to that of other causes. Insulin infusion in diabetic patients with HTG can rapidly reduce triglyceride levels. Use of apheresis is still experimental and better designed studies are needed to clarify its role in management of HTG pancreatitis. Diet, lifestyle changes, control of secondary factors are key to the treatment and medications are useful adjuncts to long term management of triglyceride levels. Control of triglyceride levels to well below 500 mg/dl can effectively prevent recurrences of pancreatitis. PMID:24172179

    Pancreatitis, which is most generally described as any inflammation of the pancreas, is a serious condition that manifests in either acute or chronic forms. Chronic pancreatitis results from irreversible scarring of the pancreas, resulting from prolonged inflammation. Six major etiologies for chronic pancreatitis have been identified: toxic/ metabolic, idiopathic, genetic, autoimmune, recurrent and severe acute pancreatitis, and obstruction. The most common symptom associated with chronic pancreatitis is pain localized to the upper-to-middle abdomen, along with food malabsorption, and eventual development of diabetes. Treatment strategies for acute pancreatitis include fasting and short-term intravenous feeding, fluid therapy, and pain management with narcotics for severe pain or nonsteroidal anti-inflammatories for milder cases. Patients with chronic disease and symptoms require further care to address digestive issues and the possible development of diabetes. Dietary restrictions are recommended, along with enzyme replacement and vitamin supplementation. More definitive outcomes may be achieved with surgical or endoscopic methods, depending on the role of the pancreatic ducts in the manifestation of disease.

    Full Text Available Treatment of pain in chronic pancreatitis includes medical, endoscopic and surgical therapy. Medical treatment may involve the use of analgesics, pancreatic enzymes, antioxidants and removal of risk factors. However, a substantial number of patients do not experience pain relief with medical treatment, and those with local complications cannot be treated medically indefinitely. These require endoscopic or surgical therapy. Endoscopic therapy has involved the use of a pancreatic sphincterotomy, b stent placement, c nasopancreatic drainage, d pseudocyst drainage, e extra corporeal shock wave lithotripsy (ESWL, and f dilatation of strictures. The current options for surgical therapy include: a partial pancreatic resections, b extended pancreatic drainage procedures (which involve additional subtotal resection of the head or a deep coring out of the head, or c pure pancreatic drainage procedures. In effect surgical procedures provide a more thorough drainage of the ductal system than pancreatic stent placement. This is especially true in the complex ductal arrangement of the head of the pancreas, where simple drainage of the duct or stent placement by endoscopy is unlikely to provide thorough drainage and relief of symptoms.

    Autoimmune pancreatitis (AIP) remains one of the rarer forms of pancreatitis but has become increasingly well recognized and widely diagnosed as it is an important differential, particularly due to the dramatic response to appropriate therapy. It is now best considered as part of a multisystem disease and the notion of “IgG4-related systemic sclerosing disease” has become widely recognized as the number of extra-pancreatic associations of AIP grows. More recently AIP has been classified into two subtypes: lymphoplasmacytic sclerosing pancreatitis (LPSP) and idiopathic duct-centric pancreatitis (IDCP) with distinct geographical, age and sex distributions for the two subtypes, in addition to different pathological characteristics. The role of imaging is crucial in AIP and should be considered in conjunction with clinical, serological, and histopathological findings to make the diagnosis. Radiologists are uniquely placed to raise the possibility of AIP and aid the exclusion of significant differentials to allow the initiation of appropriate management and avoidance of unnecessary intervention. Radiological investigation may reveal a number of characteristic imaging findings in AIP but appearances can vary considerably and the focal form of AIP may appear as a pancreatic mass, imitating pancreatic carcinoma. This review will illustrate typical and atypical appearances of AIP on all imaging modes. Emphasis will be placed on the imaging features that are likely to prove useful in discriminating AIP from other causes prior to histopathological confirmation. In addition, examples of relevant differential diagnoses are discussed and illustrated

    Purpose: To define the evolution patterns of blunt pancreatic trauma, and to point out the CT features most significant for the diagnosis. Material and Methods: Ten cases of pancreatic trauma, observed over a period of about 10 years, were analyzed in retrospect. The cases were divided into 3 groups according to the time that had elapsed between trauma and first CT: Early phase (within 72 h: n=3/10); late phase (after 10 days: n=3/10); and following pancreatic drainage (n=4/10). Results: In the early phase, one case showed a blood collection surrounding the pancreatic head and duodenum, and displacing the mesenteric vessels to the left. In the 2 other cases it was possible to demonstrate a tear in the pancreas at the neck, perpendicular to the main pancreatic axis. In the late phase in all 3 cases, one cystic lesion was present at the site of the tear, either surrounding the gland or embedded - more or less deeply - within the parenchyma. One of the lesions subsided spontaneously; the 2 others required surgery. In the postoperative phase, an external fistula was demonstrated in 2 cases following percutaneous drainage of pancreatic cysts; the fistula was fed by a cystic lesion in the pancreatic neck. In the 2 other cases a pseudocyst developed. (orig.)

    Full Text Available Tropical Calcific Pancreatitis (TCP is a type of chronic calcific nonalcoholic pancreatitis. Similar to nonalcoholic chronic pancreatitis, it presents in the second and third decades of life; however this type is reported mostly in the developing tropical and subtropical countries. It is associated with the formation of pancreatic calculi and a high probability of developing insulin-dependent diabetes mellitus. Epidemiologic studies have shown that these patients have an increased risk of developing pancreatic carcinoma. The etiology of TCP remains uncertain, with the current consensus suggesting genetics as well as possible toxicity from consuming large amounts of cassava, a tuber. Definite diagnosis of TCP requires younger age of onset, history of malnutrition, and presence of diabetes mellitus along with extensive pancreatic calcification and ductal calculi. When patients meet most but not all of these conditions the term Idiopathic Chronic Pancreatitis (ICP is used. This is a case of a 44-year-old man who presented with most features seen in TCP, and however, was diagnosed with ICP.

    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.

    Full Text Available Background. The prevalence of pancreatitis in children with digestive disorders is 5–25 %. Aim of research: to determine the prevalence of pancreatic pathology in children. Material and methods. The research was conducted on the basis of department of gastroenterology of Chernivtsi Regional Clinical Children’s Hospital during 2013–2015. Results. The overall prevalence of chronic pancreatitis in children of Chernivtsi region is 1.8 %. It should also be noted that 66 % of children with chronic gastroduodenitis and 100 % of children with duodenal bulb ulcer had ultrasound changes of pancreas. Signs of chronic pancreatitis were detected in 1 child with celiac disease and 4 children with lactose intolerance; 17 children had identified ultrasound signs of pancreatic fibrosis, and reduced elastase‑1 in stool, which can be considered as signs of chronic pancreatitis; 9 children had identified ultrasound signs of structural changes of pancreas, but the level of elastase‑1 was normal (patients with recurrent pancreatitis; 18 children had no ultrasound changes of pancreas and no deviation in the structure and the level of elastase‑1. Conclusion. The chronic pancreatitis in children is often associated with pain (epigastric paroxysmal pain with frequent changes of pain location, dyspeptic (often manifested by nausea and vo­miting and astheno-vegetative syndromes which are associated with disharmonious physical development. All patients with chronic pancreatitis were revealed to have focal or linear fibrotic changes in the parenchyma of the pancreas, nonspecific changes in coprogram and a significant reduction of elastase‑1 level in blood.

    Seventeen cases of cancers in and adjacent to the pancreas were studied by high resolution and wide field real time ultrasonographic scanner with 3.5 MHz linear array electronically focusing transducer. The result were as follows: 1. In a total of 17 cases, 7 cases were pancreatic cancers and the rests were 3 cases of ampulla of Vaster cancer, 3 cases of distal CBD cancers, and 4 cases of metastatic cancers, respectively. 2. Pancreatic cancers were located mainly in head portion, and metastatic cancers were noted in head, tail, and retropancreatic areas. 3. The sizes of all distal CBD cancer were less than 1.8 cm, usually smaller than other tumors, and the size of metastatic cancers were variable (1-6 cm). 4. The shape, margin, contour and echogenicity of the tumors were variable. 5. Pancreatic duct showed marked dilatation in one of pancreatic cancer, and mild dilatation in one of ampulla of Vater cancer. 6. The caliber of extrahepatic duct were moderately or markedly dilated in nearly all cases except 2 cases of pancreatic body cancer. 7. The pancreatic margin is partially obliterated in pancreatic and ampulla of Vater cancers but not in distal CBD cancer. 8. Gallbladder enlargement is secondary change due to the obstruction of extrahepatic bile duct. 9. Effects on the vessels are due to not only direct mass effect but direct invasion resulting in obliteration. The most commonly involved vessels are spleno-portal junction, splenic vein and portal vein. In case of pancreatic cancer in uncinate process, the superior mesenteric vessels are displaced anteriorly. 10. Surrounding metastatic lesions were suspected in pancreatic and ampulla of Vater cancer, but not seen in distal CBD cancer. 11. Ascites were seen in only two cases of metastasis

    Lipemia retinalis is a visible ophthalmic manifestation of severe hypertriglyceridemia. It may also be the only systemic sign present if triglycerides are acutely elevated in an asymptomatic patient. It may be the harbinger of more serious complications, such as acute pancreatitis and coronary artery disease. A 39-year-old woman presented for a diabetic eye examination. Dilated fundus examination found diffuse whitening of the retinal arteries and veins. The patient was asymptomatic without other remarkable ocular or systemic signs. The patient subsequently experienced an episode of acute pancreatitis. After a relative normalization of the triglyceride levels, the retina returned to baseline appearance. The patient's ocular health is monitored annually, and her endocrinologist modified the treatment regimen for improved lipid control. Although lipemia retinalis does not typically result in vision loss, it is a sign of a systemic condition that can have potentially fatal consequences. While the retinal appearance normalizes soon after resolution of the acute lipid imbalance, a multidisciplinary approach is necessary to obtain the desirable systemic outcome. Optometrists play a critical role in prompt referral of these patients for appropriate management of their lipids. Published by Elsevier Inc.

    The present article analyzes the main presentations on acute pancreatitis (AP) in Digestive Disease Week 2013. Perfusion computed tomography allows early diagnosis of pancreatic necrosis. Neutrophil gelatinase-associated lipocalin predicts the development of acute renal failure, severe AP and death. Factors associated with greater fluid sequestration in AP are alcoholic etiology, an elevated hematocrit, and the presence of criteria of systemic inflammatory response syndrome; fluid sequestration is associated with a worse outcome. True pseudocysts (fluid collections without necrosis for more than 4 weeks) are a highly infrequent complication in AP. Patients with necrotic collections have a poor prognosis, especially if associated with infection. A meta-analysis on fluid therapy suggests that early aggressive fluid administration is associated with higher mortality and more frequent respiratory complications. According to a meta-analysis, enteral nutrition initiated within 24 hours of admission improves the outcome of AP compared with later initiation of enteral nutrition. Pentoxifylline could be a promising alternative in AP; a double-blind randomized study showed that this drug reduced the length of hospital and intensive care unit stay, as well as the need for intensive care unit admission. The association of octreotide and celecoxib seems to reduce the frequency of organ damage compared with octreotide alone. Mild AP can be managed in the ambulatory setting through hospital-at-home units after a short, 24-hour admission. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Mimosa pudica is used in traditional medicine for treating various disorders such as inflammatory conditions, diarrhoea, insomnia, alopecia, urogenital infections and wounds. The present study investigated the effect of M. pudica extract (MPE) on L-arginine-induced acute necrotising pancreatitis in rats. The ethanolic extract of M. pudica leaves was studied for the presence of quercetin and gallic acid using high-performance liquid chromatography. Four groups were employed-normal control rats, L-arginine control rats (two intraperitoneal [i.p.] injections of 2 g/kg at an interval of 1 h), MPE-treated rats (400 mg/kg orally) and melatonin-treated rats (positive control 10 mg/kg i.p.), which were further divided into subgroups according to time points (24 h, 3 days and 14 days). Serum amylase, lipase, tumour necrosis factor-α (TNF-α), pancreatic amylase, nucleic acid content, protein, transforming growth factor-β1 (TGF-β1), thiobarbituric reactive substances, glutathione, nitrite/nitrate, collagen content and histopathological examination were carried out. MPE significantly improved acute necrotising pancreatitis by modulating diagnostic markers of pancreatitis such as serum lipase and pancreatic amylase, inflammation (TNF-α), and oxidative and nitrosative stress. Moreover, MPE administration induced regenerative changes in the pancreas evidenced by increased levels of pancreatic proteins, nucleic acid content and histopathology report. In addition, MPE improved TGF-β1 and collagen levels thereby preventing fibrosis. The current investigation indicates the novel role of MPE in reducing the severity of acute necrotising pancreatitis by plausible mechanisms such as anti-inflammatory and anti-fibrotic activity and by promoting repair and regeneration of the pancreas.

    The histopathology of advanced chronic alcoholic pancreatitis is dominated by cellular degeneration, atrophy and fibrosis. Sequential changes in the histopathology of alcoholic pancreatic disease has been defined and traced from initial injury to end-stage disease. These sequential histopathologies have been correlated with clinical syndrome and secretory patterns. The data are more consistent with a toxic-metabolic pathogenesis of alcoholic pancreatitis than the previous Big Duct and Small Duct hypotheses.

    Despite the identification of some efficient drugs for the treatment of metastatic pancreatic cancer, this tumor remains one of the most lethal cancers and is characterized by a strong resistance to therapies. Pancreatic cancer has some unique features including the presence of a microenvironment filled with immunosuppressive mediators and a dense stroma, which is both a physical barrier to drug penetration and a dynamic entity involved in immune system control. Therefore, the immune system has been hypothesized to play an important role in pancreatic cancer. Thus, therapies acting on innate or adaptive immunity are being investigated. Here, we review the literature, report the most interesting results and hypothesize future treatment directions.

    Diagnostic imaging is an important tool to evaluate pancreatic neoplasms. We describe the imaging features of pancreatic malignancies and their benign mimics. Accurate detection and staging are essential for ensuring appropriate selection of patients who will benefit from surgery and for preventing unnecessary surgeries in patients with unresectable disease. Ultrasound, multidetector computed tomography with multiplanar reconstruction and magnetic resonance imaging can help to do a correct diagnosis. Radiologists should be aware of the wide variety of anatomic variants and pathologic conditions that may mimic pancreatic neoplasms. The knowledge of the most important characteristic key findings may facilitate the right diagnosis.

    Although the total number of patients in these various high-risk groups is relatively small, they nevertheless provide excellent models for studying the cause, natural history, pathogenesis, and treatment of pancreatic cancer. These patients would also benefit greatly from procedures capable of detecting cancer at an early stage. This knowledge would be useful for the much commoner sporadic form of pancreatic cancer, in which diagnosis is almost always late and prognosis fatal. With early diagnosis, surgical resection before the cancer's extension beyond the organ's anatomic confines could be curative. The establishment of a National Familial Pancreatic Cancer Registry is essential and would increase the availability of these invaluable families for medical research.

Primary hydatid disease of the pancreas is very rare and acute pancreatitis secondary to hydatid cyst has rarely been reported. We report the case of a 38-year-old man who presented acute pancreatitis. A diagnosis of hydatid cyst of the pancreas, measuring 10 cm, was established by abdominal computed tomography before surgery. The treatment consisted of a distal pancreatectomy. The postoperative period was uneventful. Additionally, a review of the literature regarding case reports of acute pancreatitis due to pancreatic hydatid cyst is presented.

    A duodenum-preserving pancreatic head resection (DPPHR) was first reported by Beger et al. in 1980. However, its application has been limited to chronic pancreatitis because of it is a subtotal pancreatic head resection. In 1990, we reported duodenum-preserving total pancreatic head resection (DPTPHR) in 26 cases. This opened the way for total pancreatic head resection, expanding the application of this approach to tumorigenic morbidities such as intraductal papillary mucinous tumor (IMPT), other benign tumors, and small pancreatic cancers. On the other hand, Nakao et al. reported pancreatic head resection with segmental duodenectomy (PHRSD) as an alternative pylorus-preserving pancreatoduodenectomy technique in 24 cases. Hirata et al. also reported this technique as a new pylorus-preserving pancreatoduodenostomy with increased vessel preservation. When performing DPTPHR, the surgeon should ensure adequate duodenal blood supply. Avoidance of duodenal ischemia is very important in this operation, and thus it is necessary to maintain blood flow in the posterior pancreatoduodenal artery and to preserve the mesoduodenal vessels. Postoperative pancreatic functional tests reveal that DPTPHR is superior to PPPD, including PHSRD, because the entire duodenum and duodenal integrity is very important for postoperative pancreatic function.

    Four members of the PAX family, PAX2, PAX4, PAX6 and PAX8 are known to be expressed in the pancreas. Accumulated evidences indicate that several pancreatic expressed PAX genes play a significant role in pancreatic development/functionality and alterations in these genes are involved in the pathogenesis of pancreatic diseases. Areas covered: In this review, we summarize the ongoing research related to pancreatic PAX genes in diabetes mellitus and pancreatic neuroendocrine tumors. We dissect the current knowledge at different levels; from mechanistic studies in cell lines performed to understand the molecular processes controlled by pancreatic PAX genes, to in vivo studies using rodent models that over-express or lack specific PAX genes. Finally, we describe human studies associating variants on pancreatic-expressed PAX genes with pancreatic diseases. Expert opinion: Based on the current literature, we propose that future interventions to treat pancreatic neuroendocrine tumors and diabetes mellitus could be developed via the modulation of PAX4 and/or PAX6 regulated pathways.

    Pancreatic stellate cells (PSCs) interact with pancreatic cancer cells in the tumor microenvironment. Cell constituents including microRNAs may be exported from cells within membranous nanovesicles termed exosomes. Exosomes might play a pivotal role in intercellular communication. This study aimed to clarify the microRNA signature of PSC-derived exosomes and their effects on pancreatic cancer cells. Exosomes were prepared from the conditioned medium of immortalized human PSCs. MicroRNAs were prepared from the exosomes and their source PSCs, and the microRNA expression profiles were compared by microarray. The effects of PSC-derived exosomes on proliferation, migration, and the mRNA expression profiles were examined in pancreatic cancer cells. Pancreatic stellate cell-derived exosomes contained a variety of microRNAs including miR-21-5p. Several microRNAs such as miR-451a were enriched in exosomes compared to their source PSCs. Pancreatic stellate cell-derived exosomes stimulated the proliferation, migration and expression of mRNAs for chemokine (C - X - C motif) ligands 1 and 2 in pancreatic cancer cells. The stimulation of proliferation, migration, and chemokine gene expression by the conditioned medium of PSCs was suppressed by GW4869, an exosome inhibitor. We clarified the microRNA expression profile in PSC-derived exosomes. Pancreatic stellate cell-derived exosomes might play a role in the interactions between PSCs and pancreatic cancer cells.

    Benign and malignant pathologies of the pancreas can result in a relevant chronic disease burden. This is aggravated by morbidities resulting from surgical resections as well as from progression of the underlying condition. The aim was to summarize the current evidence regarding epidemiology, pathophysiology, diagnosis and treatment of endocrine and exocrine pancreatic insufficiency, as well as of pancreatic pseudocysts. A selective literature search was performed and a summary of the currently available data on the surgical sequelae after pancreatic resection is given. Reduction of healthy pancreatic parenchyma down to 10-15 % leads to exocrine insufficiency with malabsorption and gastrointestinal complaints. Orally substituted pancreatic enzymes are the therapy of choice. Loss of pancreatic islets and/or islet function leads to endocrine insufficiency and pancreoprivic diabetes mellitus. Inflammatory, traumatic and iatrogenic injuries of the pancreas can lead to pancreatic pseudocysts, which require endoscopic, interventional or surgical drainage if symptomatic. Finally, pancreatic surgery harbors the long-term risk of gastrointestinal anastomotic ulcers, bile duct stenosis, portal vein thrombosis and chronic pain syndrome. As the evidence is limited, an interdisciplinary and individually tailored approach for delayed pancreatic morbidity is recommended.

Several reports have been published describing pancreatic cancer in the setting of AIP. Case Report. The case of a 53-year-old man who presented with abdominal pain, jaundice, and radiological features of autoimmune pancreatitis, with a “sausage-shaped” pancreas and bulky pancreatic head with portal vein impingement, is presented. He had a normal serum IgG4 and only mildly elevated Ca-19.9. Initial endoscopic ultrasound-(EUS- guided fine-needle aspiration (FNA of the pancreas revealed an inflammatory sclerosing process only. A repeat EUS guided biopsy following biliary decompression demonstrated both malignancy and features of autoimmune pancreatitis. At laparotomy, a uniformly hard, bulky pancreas was found with no sonographically definable mass. A total pancreatectomy with portal vein resection and reconstruction was performed. Histology revealed adenosquamous carcinoma of the pancreatic head and autoimmune pancreatitis and squamous metaplasia in the remaining pancreas. Conclusion. This case highlights the diagnostic and management difficulties in a patient with pancreatic cancer in the setting of serum IgG4-negative, Type 2 AIP.

    Research highlights: → Recent studies have shown that pancreatic stellate cells (PSCs) promote the progression of pancreatic cancer. → Pancreatic cancer cells co-cultured with PSCs showed loose cell contacts and scattered, fibroblast-like appearance. → PSCs decreased the expression of epithelial markers but increased that of mesenchymal markers, along with increased migration. → This study suggests epithelial-mesenchymal transition as a novel mechanism by which PSCs contribute to the aggressive behavior of pancreatic cancer cells. -- Abstract: The interaction between pancreatic cancer cells and pancreatic stellate cells (PSCs), a major profibrogenic cell type in the pancreas, is receiving increasing attention. There is accumulating evidence that PSCs promote the progression of pancreatic cancer by increasing cancer cell proliferation and invasion as well as by protecting them from radiation- and gemcitabine-induced apoptosis. Because epithelial-mesenchymal transition (EMT) plays a critical role in the progression of pancreatic cancer, we hypothesized that PSCs promote EMT in pancreatic cancer cells. Panc-1 and SUIT-2 pancreatic cancer cells were indirectly co-cultured with human PSCs isolated from patients undergoing operation for pancreatic cancer. The expression of epithelial and mesenchymal markers was examined by real-time PCR and immunofluorescent staining. The migration of pancreatic cancer cells was examined by scratch and two-chamber assays. Pancreatic cancer cells co-cultured with PSCs showed loose cell contacts and a scattered, fibroblast-like appearance. The expression of E-cadherin, cytokeratin 19, and membrane-associated β-catenin was decreased, whereas vimentin and Snail (Snai-1) expression was increased more in cancer cells co-cultured with PSCs than in mono-cultured cells. The migration of pancreatic cancer cells was increased by co-culture with PSCs. The PSC-induced decrease of E-cadherin expression was not altered by treatment with anti

    Generation of unlimited functional pancreatic β cells is critical for the study of pancreatic biology and treatment of diabetes mellitus. Recent advances have suggested several promising directions, including directed differentiation of pancreatic β cells from pluripotent stem cells, reprogramming of pancreatic β cells from other types of somatic cells, and stimulated proliferation and enhanced functions of existing pancreatic β cells. Small molecules are useful in generating unlimited numbers of functional pancreatic cells in vitro and could be further developed as drugs to stimulate endogenous pancreatic regeneration. Here, we provide an updated summary of recent major achievements in pancreatic β cell differentiation, reprogramming, proliferation, and function. These studies will eventually lead to significant advances in the field of pancreatic biology and regeneration. © The Author 2017.

  16. Analysis of related risk factors for pancreatic fistula after pancreaticoduodenectomy

    Directory of Open Access Journals (Sweden)

    Qi-Song Yu

    2016-08-01

    Full Text Available Objective: To explore the related risk factors for pancreatic fistula after pancreaticoduodenectomy to provide a theoretical evidence for effectively preventing the occurrence of pancreatic fistula. Methods: A total of 100 patients who were admitted in our hospital from January, 2012 to January, 2015 and had performed pancreaticoduodenectomy were included in the study. The related risk factors for developing pancreatic fistula were collected for single factor and Logistic multi-factor analysis. Results: Among the included patients, 16 had pancreatic fistula, and the total occurrence rate was 16% (16/100. The single-factor analysis showed that the upper abdominal operation history, preoperative bilirubin, pancreatic texture, pancreatic duct diameter, intraoperative amount of bleeding, postoperative hemoglobin, and application of somatostatin after operation were the risk factors for developing pancreatic fistula (P<0.05. The multi-factor analysis showed that the upper abdominal operation history, the soft pancreatic texture, small pancreatic duct diameter, and low postoperative hemoglobin were the dependent risk factors for developing pancreatic fistula (OR=4.162, 6.104, 5.613, 4.034, P<0.05. Conclusions: The occurrence of pancreatic fistula after pancreaticoduodenectomy is closely associated with the upper abdominal operation history, the soft pancreatic texture, small pancreatic duct diameter, and low postoperative hemoglobin; therefore, effective measures should be taken to reduce the occurrence of pancreatic fistula according to the patients’ own conditions.

    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. (orig.) [de

    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.

    1981-01-01

    Adenocarcinoma of the pancreas is not a radioresistant neoplasm, as was once believed. The data now suggest that in some instances this cancer may be radiocurable. This fact seems to justify the risk of pancreatic biopsy even in the face of unresectable disease, for it is well known that many benign conditions imitate pancreatic cancer. Clinical benefit from radiation for pancreatic cancer treatment is dose related. Careful delineation of tumor margins, precision treatment planning, and precision dose delivery can minimize damage to adjacent normal tissues. Interstitial implantation and intraoperative electron beam therapy are being studied as methods of accurate dose delivery for pancreatic cancer. Fractionation studies and high LET studies are in embryonic stages. Combined modality regimens may have much to offer in terms of improved palliation and survival for patients with localized adenocarcinoma of the pancreas

    Full Text Available Vildagliptin has not been associated with the development of acute pancreatitis in postmarketing reports except one case report from Sydney, Australia. We present the case report of 42 year old male, diabetic, with no historyof alcohol use, on vildagliptin 50 mg and metformin 500 mg daily since 6 months, who presented with severe abdominal pain radiating to back, nausea and fever. On evaluation, serum pancreatic enzymes were elevated, triglycerides were not raised and ultrasound showed swollen and echogenic pancreas, loss of peripancreatic fat plane and pancreatic duct was not dilated. Vildagliptin was stopped and the pancreatits resolved. On Follow up, no secondary cause was not identified. This appears to be the first reported case of acute pancreatitis from India probably attributable to use of vildagliptin, thus raising the possibility that this rare reaction may be a class effect of the DPP-4 inhibitors.

    Acute pancreatitis is one of the most common GI conditions requiring acute hospitalisation and has a rising incidence. In recent years, important insights on the management of acute pancreatitis have been obtained through numerous randomised controlled trials. Based on this evidence, the treatment of acute pancreatitis has gradually developed towards a tailored, multidisciplinary effort, with distinctive roles for gastroenterologists, radiologists and surgeons. This review summarises how to diagnose, classify and manage patients with acute pancreatitis, emphasising the evidence obtained through randomised controlled trials. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    As endoscopic ultrasound (EUS) is the most sensitive imaging modality for diagnosing pancreatic disorders, it can demonstrate subtle alterations in the pancreatic parenchymal and ductal structure even before traditional imaging and functional testing demonstrate any abnormality. In spite...... of this fact and abundant literature, the exact role of EUS in the diagnosis of chronic pancreatitis (CP) is still not established. The EUS features to diagnose CP have evolved over a period from a pure qualitative approach to more advanced and complicated scoring systems incorporating multiple parenchymal...... to define the exact role of these criteria. The measurement of strain ratio using quantitative EUS elastography and thus allowing quantification of pancreatic fibrosis seems to be a promising new technique....

    2014-01-01

    Full Text Available Acute pancreatitis caused by severe gestational hypertriglyceridemia is a rare complication of pregnancy. Acute pancreatitis has been well associated with gallstone disease, alcoholism, or drug abuse but rarely seen in association with severe hypertriglyceridemia. Hypertriglyceridemia may occur in pregnancy due to normal physiological changes leading to abnormalities in lipid metabolism. We report a case of severe gestational hypertriglyceridemia that caused acute pancreatitis at full term and was successfully treated with postpartum therapeutic plasma exchange. Patient also developed several other complications related to her substantial hypertriglyceridemia including preeclampsia, chylous ascites, retinal detachment, pleural effusion, and chronic pericarditis. This patient had no previous family or personal history of lipid abnormality and had four successful prior pregnancies without developing gestational hypertriglyceridemia. Such a severe hypertriglyceridemia is usually seen in patients with familial chylomicronemia syndromes where hypertriglyceridemia is exacerbated by the pregnancy, leading to fatal complications such as acute pancreatitis.

    2011-01-01

    Pancreatic cancer is the fourth leading cause of cancer related death. The difficulty in detecting pancreatic cancer at an early stage, aggressiveness and the lack of effective therapy all contribute to the high mortality. Epidermal growth factor receptor (EGFR) is a transmembrane glycoprotein, which is expressed in normal human tissues. It is a member of the tyrosine kinase family of growth factors receptors and is encoded by proto-oncogenes. Several studies have demonstrated that EGFR is over-expressed in pancreatic cancer. Over-expression correlates with more advanced disease, poor survival and the presence of metastases. Therefore, inhibition of the EGFR signaling pathway is an attractive therapeutic target. Although several combinations of EGFR inhibitors with chemotherapy demonstrate inhibition of tumor-induced angiogenesis, tumor cell apoptosis and regression in xenograft models, these benefits remain to be confirmed. Multimodality treatment incorporating EGFR-inhibition is emerging as a novel strategy in the treatment of pancreatic cancer

    Between 1980 to 1989, 24 patients with unresectable pancreatic cancer (10 with localized tumor alone and 14 with distant metastases) have been treated with external beam radiation at Sapporo National Hospital, Hokkaido Cancer Center. Response rate of pancreatic tumor treated with external beam radiation was 33.3% (7/21) with no complete response. Median survival time of the patients with localized tumor was 10 months and that of the patients with distant metastases was 3 months. Relief of pain occurred in 92.9% (12/13) of patients having pain due to pancreatic tumor and in 75% (3/4) of patients having pain due to bone metastases. Major complication was gastric ulcer which developed in 5 patients of 21 patients given stomach irradiation. We concluded that unresectable pancreatic cancer would be frequently indicated for radiotherapy. (author).

    Histologic characteristics have proven to be very useful for classifying different types of tumors of the pancreas. As a result, the major tumor types in the pancreas have long been classified based on their microscopic appearance. Recent advances in whole exome sequencing, gene expression profiling, and knowledge of tumorigenic pathways have deepened our understanding of the underlying biology of pancreatic neoplasia. These advances have not only confirmed the traditional histologic classification system, but also opened new doors to early diagnosis and targeted treatment. This review discusses the histopathology, genetic and epigenetic alterations and potential treatment targets of the five major malignant pancreatic tumors - pancreatic ductal adenocarcinoma, pancreatic neuroendocrine tumor, solid-pseudopapillary neoplasm, acinar cell carcinoma and pancreatoblastoma.

    The objectives of the present study were to determine nutritional status, pancreatic function, and morphological changes of the pancreatic remnant after pancreatic tumor resection in children. The nutritional status was evaluated by the patterns of growth. Pancreatic function was evaluated by using a questionnaire, the Bristol stool form chart, the serum levels of fasting blood glucose, and hemoglobin A1c (HbA1c). Morphological changes of the pancreatic remnant were evaluated by computed tomography, magnetic resonance image, or magnetic resonance cholangiopancreatography. The present study consisted of 6 patients with pancreatic tumor (5 solid pseudopapillary tumors of the pancreas and 1 pancreatoblastoma) who underwent the following operations: tumor enucleation (3), distal pancreatectomy with splenectomy (1), and pylorus-preserving pancreatoduodenectomy (PPPD [2]). The serum levels of HbA1c have been gradually elevated in 2 patients with PPPD. A significant decrease in pancreatic parenchymal thickness and dilatation of the main pancreatic duct were observed in 2 patients with PPPD. Endocrine pancreatic insufficiency after PPPD may be explainable by obstructive pancreatitis after operation. Taking together the results of pancreatic endocrine function and morphological changes of pancreatic remnant after PPPD, tumor enucleation should be considered as surgical approach in children with pancreas head tumor whenever possible.

    2005-08-01

    Major injuries of the pancreas are uncommon, but may result in considerable morbidity and mortality because of the magnitude of associated vascular and duodenal injuries or underestimation of the extent of the pancreatic injury. Prognosis is influenced by the cause and complexity of the pancreatic injury, the amount of blood lost, duration of shock, speed of resuscitation and quality and nature of surgical intervention. Early mortality usually results from uncontrolled or massive bleeding due to associated vascular and adjacent organ injuries. Late mortality is a consequence of infection or multiple organ failure. Neglect of major pancreatic duct injury may lead to life-threatening complications including pseudocysts, fistulas, pancreatitis, sepsis and secondary haemorrhage. Careful operative assessment to determine the extent of gland damage and the likelihood of duct injury is usually sufficient to allow planning of further management. This strategy provides a simple approach to the management of pancreatic injuries regardless of the cause. Four situations are defined by the extent and site of injury: (i) minor lacerations, stabs or gunshot wounds of the superior or inferior border of the body or tail of the pancreas (i.e. remote from the main pancreatic duct), without visible duct involvement, are best managed by external drainage; (ii) major lacerations or gunshot or stab wounds in the body or tail with visible duct involvement or transection of more than half the width of the pancreas are treated by distal pancreatectomy; (iii) stab wounds, gunshot wounds and contusions of the head of the pancreas without devitalisation of pancreatic tissue are managed by external drainage, provided that any associated duodenal injury is amenable to simple repair; and (iv) non-reconstructable injuries with disruption of the ampullary-biliary-pancreatic union or major devitalising injuries of the pancreatic head and duodenum in stable patients are best treated by

    Chronic pancreatitis (CP) is characterized by abnormal pancreatic morphology and impaired endocrine and exocrine function. However, little is known about the relationship between pancreatic morphology and function, and also the association with the etiology and clinical manifestations of CP. The aim was to explore pancreatic morphology and function with advanced MRI in patients with CP and healthy controls (HC) METHODS: Eighty-two patients with CP and 22 HC were enrolled in the study. Morphological imaging parameters included pancreatic main duct diameter, gland volume, fat signal fraction and apparent diffusion coefficient (ADC) values. Functional secretin-stimulated MRI (s-MRI) parameters included pancreatic secretion (bowel fluid volume) and changes in pancreatic ADC value before and after secretin stimulation. Patients were classified according to the modified Cambridge and M-ANNHEIM classification system and fecal elastase was collected. All imaging parameters differentiated CP patients from HC; however, correlations between morphological and functional parameters in CP were weak. Patients with alcoholic and non-alcoholic etiology had comparable s-MRI findings. Fecal elastase was positively correlated to pancreatic gland volume (r = 0.68, P = 0.0016) and negatively correlated to Cambridge classification (r = -0.35, P pancreatic gland volume was significantly decreased in the severe stages of CP (P = 0.001). S-MRI provides detailed information about pancreatic morphology and function and represents a promising non-invasive imaging method to characterize pancreatic pathophysiology and may enable monitoring of disease progression in patients with CP.

    Surgery, when possible, is the treatment of choice for the uncommon endocrine tumours of pancreas. Unresectable cases are usually treated with cytostatic drugs or α-interferon. We describe a patient with unresectable, locally advanced endocrine pancreatic carcinoma (measuring 5 x 5 x 6 cm) that was totally cured by external radiation therapy only (40 Gy). This case together with four cases in the literature indicate that external radiation therapy should be considered in locally unresectable endocrine pancreatic carcinomas. (author)

Such a study proves to be highly informative permitting early detection of false pancreatic cysts and observation of the stages of their formation and development of complications. The ultrasound method has advantages for the investigation of patients in early time of false cyst formation and provides an opportunity to detect formations of minimum sizes

    Radiological and ultrasonographic studies of ten patients with surgically confirmed pancreatic pseudocysts were reviewed. All of them were male, with previous story of chronic alcoholism and clinical evidences of pancreatitis. The most important radiological finding consisted of a mass opacifying the epigastrium, displacing the stomach and bowel loops. ultrasound studies showed that the lesions were predominantly cystic, rounded or oval-shaped with smooth or irregular contours and of various sizes.

    We report a case of histopathologically proven autoimmune pancreatitis in an 11-year-old boy. Abdominal US and MRI showed a focal swelling of the pancreatic head, the latter also showing delayed contrast enhancement. There was diffuse irregular pancreatic duct narrowing, compression of the intrapancreatic common bile duct, and mild proximal biliary dilatation on MR cholangiopancreatography. Laboratory results revealed normal serum IgG and subclass 4 with negative autoimmune antibodies, and slightly elevated carbohydrate antigen 19-9. This highlights the differentiation of autoimmune pancreatitis from pancreatic head cancer and, to a lesser extent, other forms of pancreatitis in children. (orig.)

    Full Text Available Abstract Introduction Mediastinal pancreatic pseudocysts represent a rare complication of acute or chronic pancreatitis. Case presentation A 55-year-old man with a history of chronic pancreatitis was admitted with intermittent dyspnea, dysphagia and weight loss. Chest X-ray, computed tomography and magnetic resonance imaging revealed a large paracardial pancreatic pseudocyst causing cardiac and esophageal compression. Conclusion Mediastinal pancreatic pseudocysts are a rare complication of chronic pancreatitis. These pseudocysts may lead to isolated thoracic symptoms. For accurate diagnostic and therapy planning, a multimodal imaging approach is necessary.

    Twenty-eight patients with pancreatic carcinoma, 23 (82 %) of whom had Stage III or IV, received intraoperative radiotherapy (IOR) with curative or non-curative surgery. Electron beams (10 to 18 MeV) with doses of 20 to 40 Gy were delivered to the tumor. Eight of 26 patients with unresectable tumor had postoperative external irradiation of 10.5 to 50 Gy. Abdominal and back pain relief was achieved after IOR in 12 (71 %) and in 6 (60 %) of the 26 patients, respectively. Appetite was promoted in 11 patients. In the case of unresectable carcinoma, survival time tended to prolong in the 8 patients receiving both IOR and postoperative external irradiation. One patient developed perforation of the colon probably caused by IOR. (Namekawa, K.)

    Full text: Learning objectives: to learn about the main imaging diagnostic findings of AIP and the International Consensus Diagnostic Criteria (ICDC); to understand the best strategies for distinguishing AIP from pancreatic cancer; to emphasise the central role of radiology in the era of “clinical decision making” Autoimmune Pancreatitis (AIP) was first described in 1961 and represents a rare form of immune mediated chronic pancreatitis which is characterised by a marked infiltration of lymphocytes and plasma cells into pancreatic tissue. Whilst the majority of cases present with diffuse gland involvement, approximately 30% of patient’s demonstrate either segmental or focal involvement of the pancreas. Clinical presentation is very variable with patients describing a range of symptoms. Imaging plays a central role in the diagnosis and management of AIP and knowledge of the radiological appearances, which can vary significantly due to the various degrees of fibrosis and inflammatory infiltrate, is critical. Cardinal features include focal or diffuse pancreatic enlargement with the loss of normal lobular architecture. Post contrast enhancement features of the pancreas may also be useful. In addition, pancreatic duct involvement as demonstrated by single or multiple focal strictures with limited more proximal dilatation is common as well as infiltration of the common bile duct.Whilst multimodality appearances may suggest a diagnosis of AIP correlation with clinical history, serology and histopathology is mandatory in order to accurately diagnose atypical cases

    Pancreas secretes fluid rich in digestive enzymes and bicarbonate. The alkaline secretion is important in buffering of acid chyme entering duodenum and for activation of enzymes. This secretion is formed in pancreatic ducts, and studies to date show that plasma membranes of duct epithelium express H(+)/HCO(3)(-) transporters, which depend on gradients created by the Na(+)/K(+)-ATPase. However, the model cannot fully account for high-bicarbonate concentrations, and other active transporters, i.e. pumps, have not been explored. Here we show that pancreatic ducts express functional gastric and non-gastric H(+)-K(+)-ATPases. We measured intracellular pH and secretion in small ducts isolated from rat pancreas and showed their sensitivity to H(+)-K(+) pump inhibitors and ion substitutions. Gastric and non-gastric H(+)-K(+) pumps were demonstrated on RNA and protein levels, and pumps were localized to the plasma membranes of pancreatic ducts. Quantitative analysis of H(+)/HCO(3)(-) and fluid transport shows that the H(+)-K(+) pumps can contribute to pancreatic secretion in several species. Our results call for revision of the bicarbonate transport physiology in pancreas, and most likely other epithelia. Furthermore, because pancreatic ducts play a central role in several pancreatic diseases, it is of high relevance to understand the role of H(+)-K(+) pumps in pathophysiology.

    Mild pancreatitis has been reported as a consequence of anorexia nervosa, bulimia nervosa, or what has been termed the "dietary chaos syndrome". Either chronic malnutrition, or refeeding after periods of malnutrition, may precipitate acute pancreatitis through several pathogenetic mechanisms. A 26-year-old woman with a ten-year history of anorexia and bulimia presented with a third episode of acute pancreatitis in three months. The patient had been abstinent from alcohol for many years. Imaging studies during all three admissions failed to identify any biliary disease, including gallstones or biliary sludge. A cholecystectomy was performed, with a normal intraoperative cholangiogram, and no abnormalities on pathologic examination of the gallbladder and bile. The patient was discharged on hospital day 10 with no pain, and she has begun to return to regular eating habits. Pancreatitis has not recurred after 6 months of follow up. We have identified 14 cases in the literature of acute pancreatitis associated with anorexia or bulimia. In the absence of evidence for gallstone, alcohol or metabolic etiologies, eating disorders may contribute to the pathophysiology of some idiopathic cases of pancreatitis.

    The pancreatic trauma is rare, compared with the injuries of the other abdominal organs and occurs in 0.2-6 per cent of the cases of abdominal trauma. The aim of this essay is to demonstrate the Authors' experience in the treatment of five cases of pancreatic injury during the last five years, as well as to retrospect the contemporary bibliography, connected with the diagnostic and curative approach of the pancreatic trauma. The diagnosis of the pancreatic trauma is difficult and many times, late. In their experience of pancreatic trauma, the Authors ascertained the pancreatic injury during the laparotomy which was made in order to treat other abdominal injuries. The surgical techniques were chosen taking into account the extent of the injury, the detection and the existence of accompanying. Marginal resection of pancreas, splenectomy and drainage were applied to three patients, suture of the pancreas and drainage to one patient, drainage alone and treatment of synchronous rupture of the duodenum to one patient. The mortality was 0%. Came whereas the morbidity came basically on the seriousness of the accompanying injuries.

    Chronic pancreatitis (CP) is a rare disease in Chile, without a clear explanation for this low prevalence. To analyze the characteristics of our patients with pancreatitis. Retrospective analysis of a database of patients with pancreatitis of a clinical hospital. Morphological proof of diagnosis (calcifications/calculi, alterations of ducts, local complication or histology) was obtained for every patient. History of acute pancreatitis was recorded and exocrine-endocrine function was assessed. We retrieved information of 121 patients with pancreatitis (86 males) in a period of 20 years. The number of cases increased markedly every five years. The calculated incidence and prevalence was 0.8/100,000/year and 6/100,000, respectively. Pancreatic calcifications were initially observed in 93 patients and became evident during the follow-up in another six patients. Severe pain or local complications occurred in 27 patients, requiring surgery in 10 or endoscopic treatment in 15. During the years of follow-up, 55 patients were free of symptoms. Exocrine and endocrine insufficiency was demonstrated and treated in 81 and 67 patients, respectively. Alcoholic etiology was evident in 40% of patients. In 29% no etiology was identified. Mapuche origin was exceptional. Late diagnosis of CP is common, since most of our patients presented with advanced stages. Even though CP is increasingly diagnosed in our hospitals, the number of cases is still far fewer when compared to other countries. Underdiagnosis alone cannot explain this difference and genetic factors might be of importance.

    To evaluate the role of palliative surgical treatment in patients with advanced pancreatic carcinoma. Study Design: Case series. Place and Duration of Study: Surgical Ward of Khyber Teaching Hospital, Peshawar, from January 2005 to January 2009. Methodology: The study included patients with pancreatic carcinoma admitted with advanced, unresectable carcinoma of the pancreas. Patients with resectable tumours and with previous history of gastric or biliary surgery were excluded. Palliative procedures were performed after assessment of the tumour and its confirmation as unresectable on ultrasound and CT scan + ERCP. Postoperatively all patients were referred to oncologist. Complications and mortality were noted. Results: There were 40 patients, including 24 males and 16 females with mean age 58.72 +- 6.42 years. The most common procedure performed was triple bypass in 21 (52.50%) patients followed by choledocho-, cholecysto-, hepaticoand gastro-jejunostomy in various combinations. Wound infection occurred in 7 patients and was more common in patients with co-morbidities. Biliary leakage occurred in 03 patients. Postoperative cholangitis occurred in 3 patients while 7 patients had minor leak from the drain site. Four patients developed UTI, while 5 patients had signs of delayed gastric emptying. Two patients had upper gastrointestinal bleeding. Three patients died due to septicemia and multiple organs failure. Rest of the patients were discharged in stable state. The mean hospital stay was 8.40 +- 3.48 days and median survival was 7.72 +- 2.39 months. Conclusion: Surgical palliation for the advanced carcinoma pancreas can improve the quality of life of patients and is associated with minimum morbidity and mortality. (author)

    Recently the physiological relationship between the phospholipid effect and secretagogue-induced cellular function has begun to be understood. In this study, the authors investigated acute and chronic effects of ethanol on phosphatidylinositol (PI) synthesis and breakdown in pancreatic acini. Five pairs of male Wistar rats were intragastrically infused for 30 days with high fat diet (25% total calories) plus ethanol or isocaloric dextrose. After intoxication, isolated in HEPES media, followed by 30 min incubation with CCK-8 (0, 100, 300 or 600 pM) and ethanol (0 or 100 mM). Acinar lipids were extracted and counted for labeled PI. Incorporation of 3 H-inositol into alcoholic acinar PI was reduced to 38.2% of that in controls. A percent maximal PI break down by CCK-8 was similar in the two groups (13-24% of basal). However, the magnitude of PI breakdown was markedly lower in alcoholic acini (482 vs 1081 dpm) due to the decreased PI synthesis rate. The presence of 100 mM ethanol in the media further inhibited the breakdown by 50% in this group. These results strongly indicate that chronic ethanol intoxication inhibits PI synthesis and breakdown in pancreatic acini, and that this inhibition can be potentiated by acute ethanol administration

    Acute pancreatitis is an inflammatory condition caused by intracellular activation and extravasation of inappropriate proteolytic enzymes determining destruction of pancreatic parenchyma and peripancreatic tissues. This is a fairly common clinical condition with two main presentations, namely, endematous pancreatitis - a less severe presentation - and necrotizing pancreatitis - the most severe presentation that affects a significant part of patients. The radiological evaluation, particularly by computed tomography, plays a fundamental role in the definition of the management of severe cases, especially regarding the characterization of local complications with implications in the prognosis and in the definition of the therapeutic approach. New concepts include the subdivision of necrotizing pancreatitis into the following presentations: pancreatic parenchymal necrosis with concomitant peripancreatic tissue necrosis, and necrosis restricted to peripancreatic tissues. Moreover, there was a systematization of the terms acute peripancreatic fluid collection, pseudocyst, post-necrotic pancreatic/peripancreatic fluid collections and walled-off pancreatic necrosis. The knowledge about such terms is extremely relevant to standardize the terminology utilized by specialists involved in the diagnosis and treatment of these patients. (author)

    Autoimmune pancreatitis (AIP) has the potential to progress to a chronic state that forms pancreatic stones. The aim of this study was to clarify the risk factors underlying pancreatic stone formation in AIP. Sixty-nine patients with AIP who had been followed for at least 3 years were enrolled for evaluation of clinical and laboratory factors as well as computed tomography and endoscopic retrograde cholangiopancreatography findings. During the course of this study, increased or de novo stone formation was seen in 28 patients, who were defined as the stone-forming group. No stones were observed in 32 patients, who were defined as the non-stone-forming group. Nine patients who had stones at diagnosis but showed no change during the course of this study were excluded from our cohort. Univariate analysis revealed no significant differences in clinical or laboratory factors associated with AIP-specific inflammation between the two groups. However, pancreatic head swelling (P = 0.006) and narrowing of both Wirsung's and Santorini's ducts in the pancreatic head region (P = 0.010) were significantly more frequent in the stone-forming group. Furthermore, multivariate analysis identified Wirsung and Santorini duct narrowing at diagnosis as a significant independent risk factor for pancreatic stone formation (OR 4.4, P = 0.019). A primary risk factor for pancreatic stone formation in AIP was narrowing of both Wirsung's and Santorini's ducts, which most presumably led to pancreatic juice stasis and stone development.

    The effect of intravenous infusion of synthetic human pancreatic polypeptide (HPP) or a rabbit anti-PP serum on pancreatic exocrine secretion was studied in 10 dogs with gastric and Thomas duodenal cannulas. The infusion of HPP, achieved a plasma PP concentration that mimicked the peak plasma concentration of PP in both interdigestive and postprandial states. This dose of HPP significantly inhibited pancreatic secretion in the interdigestive state. By contrast, immunoneutralization of circulating PP by a rabbit anti-PP serum resulted in significant increases in both interdigestive and postprandial pancreatic secretion, including water, bicarbonate, and protein. The increase in the pancreatic secretion paralleled a decrease in circulating PP level, which lasted for as long as 5 days. Furthermore, the anti-PP serum blocked the inhibitory action of exogenous HPP on pancreatic exocrine secretion. The present study indicates that endogenous PP plays a significant role in the regulation of the pancreatic exocrine secretion in both interdigestive and digestive states. Thus the authors conclude that PP is another hormone regulating pancreatic exocrine secretion in dogs

    The most common aetiologies of acute pancreatitis (AP) are gallstones, alcohol and idiopathic. The impact of the aetiology of AP on the extent and morphology of pancreatic and extrapancreatic necrosis (EXPN) has not been clearly established. The aim of the present study was to assess the influence of aetiology on the presence and location of pancreatic necrosis in patients with AP. We carried out a post-hoc analysis of a previously established multicentre cohort of patients with AP in whom a computed tomography was available for review. Clinical data were obtained from the medical records. All computed tomographies were revised by the same expert radiologist. The impact of aetiology on pancreatic and EXPN was calculated. In total, 159 patients with necrotizing pancreatitis were identified from a cohort of 285 patients. The most frequent aetiologies were biliary (105 patients, 37%), followed by alcohol (102 patients, 36%) and other aetiologies including idiopathic (78 patients, 27%). No relationship was found between the aetiology and the presence of pancreatic necrosis, EXPN, location of pancreatic necrosis or presence of collections. We found no association between the aetiology of AP and the presence, extent and anatomical location of pancreatic necrosis.

    To determine the prevalence and time course of pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis. Relevant literature cited in three major biomedical journal databases (EMBASE, MEDLINE, and Scopus) was reviewed independently by two authors. There were no language constraints but the search was limited to human studies. Studies included were cohort studies of adult patients who were discharged after an attack of acute pancreatitis. Patients were excluded if they were under 18 years of age or had a previous diagnosis of prediabetes or diabetes mellitus, pancreatic exocrine insufficiency, or chronic pancreatitis. The main outcome measure was the prevalence of concomitant pancreatic exocrine insufficiency in patients who were diagnosed with prediabetes and diabetes mellitus after an attack of acute pancreatitis. Subgroup analysis was conducted for patients who were diagnosed with prediabetes only and those who were diagnosed with diabetes mellitus only. Subgroup analysis looking at the time course of concomitant pancreatic exocrine and endocrine insufficiency was also conducted. Pooled prevalence and corresponding 95% confidence intervals were calculated for all outcome measures and P-values pancreatitis was 43% (95%CI: 30%-56%). The pooled prevalence of pancreatic exocrine insufficiency in individuals after acute pancreatitis was 29% (95%CI: 19%-39%). The prevalence of concomitant pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes was 40% (95%CI: 25%-55%). The prevalence of concomitant pancreatic exocrine insufficiency among individuals with prediabetes alone and diabetes mellitus alone was 41% (95%CI: 12%-75%) and 39% (95%CI: 28%-51%), respectively. Further analysis showed that the prevalence of concomitant pancreatic exocrine insufficiency in individuals with prediabetes or diabetes decreases over time after an attack of acute pancreatitis

    Background: Because survival after pancreaticoduodenectomy for cancer is limited, it is difficult to assess longterm pancreaticojejunal anastomotic patency. However, in patients with benign disease, pancreaticojejunal anastomotic stenosis may become problematic. What happens when pancreaticojejunal anastomosis revision is undertaken? Methods: Patients undergoing pancreatic anastomotic revision after pancreatic head resection for benign disease between 1997 and 2007 at the Medical University of South Carolina were identified. A retrospective chart review and analysis were undertaken with the approval of the Institutional Review Board for the Evaluation of Human Subjects. Longterm follow-up was obtained by patient survey at a clinic visit or by telephone. Results: During the study period, 237 patients underwent pancreatic head resection. Of these, 27 patients (17 women; median age 42 years) underwent revision of pancreaticojejunal anastomosis. Six patients (22%) had a pancreatic leak or abscess at the time of the index pancreatic head resection. The indication for revision of anastomosis was intractable pain. All patients underwent preoperative magnetic resonance cholangiopancreatography (MRCP), which indicated anastomotic stricture in 18 patients (63%). Nine other patients underwent exploration based on clinical suspicion caused by recurrent pancreatitis and stenosis was confirmed at the time of surgery. Six patients (22%) had perioperative complications after revision. The median length of stay was 12 days. There were no perioperative deaths; however, late mortality occurred in four patients (15%). Six of 23 survivors (26%) at the time of follow-up (median 56 months) reported longterm pain relief. Conclusions: Stricture of the pancreaticojejunal anastomosis after pancreatic head resection presents with recurrent pancreatitis and pancreatic pain. MRCP has good specificity in the diagnosis of anastomotic obstruction, but lacks sensitivity. Pancreaticojejunal revision

    Highlights: ► Pancreatic stellate cells (PSCs) promote the progression of pancreatic cancer. ► Pancreatic cancer cells co-cultured with PSCs showed enhanced spheroid formation. ► Expression of stem cell-related genes ABCG2, Nestin and LIN28 was increased. ► Co-injection of PSCs enhanced tumorigenicity of pancreatic cancer cells in vivo. ► This study suggested a novel role of PSCs as a part of the cancer stem cell niche. -- Abstract: The interaction between pancreatic cancer cells and pancreatic stellate cells (PSCs), a major profibrogenic cell type in the pancreas, is receiving increasing attention. There is accumulating evidence that PSCs promote the progression of pancreatic cancer by increasing cancer cell proliferation and invasion as well as by protecting them from radiation- and gemcitabine-induced apoptosis. Recent studies have identified that a portion of cancer cells, called “cancer stem cells”, within the entire cancer tissue harbor highly tumorigenic and chemo-resistant phenotypes, which lead to the recurrence after surgery or re-growth of the tumor. The mechanisms that maintain the “stemness” of these cells remain largely unknown. We hypothesized that PSCs might enhance the cancer stem cell-like phenotypes in pancreatic cancer cells. Indirect co-culture of pancreatic cancer cells with PSCs enhanced the spheroid-forming ability of cancer cells and induced the expression of cancer stem cell-related genes ABCG2, Nestin and LIN28. In addition, co-injection of PSCs enhanced tumorigenicity of pancreatic cancer cells in vivo. These results suggested a novel role of PSCs as a part of the cancer stem cell niche.

    Full Text Available Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP. Pancreatic duct guidewire placement method (PGW is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP. The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts. This study aimed to investigate whether PGW increased the risk of PEP in patients with pancreatic duct diameter ≤ 3 mm.We analyzed 332 patients with pancreatic duct ≤ 3 mm who performed first time ERCP session. The primary endpoint was the rate of adverse event of PEP. We evaluated the risk of PEP in patients who had undergone PGW compared to those who had not, using the inverse probability of treatment weighting (IPTW analysis.PGW was found to be an independent risk factor for PEP by univariate analysis (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.12-5.38; p = 0.03 after IPTW in patients with pancreatic duct diameter ≤ 3 mm. Adjusted for all covariates, PGW remained an independent risk factor for PEP (OR, 3.12; 95% CI, 1.33-7.33; p = 0.01.Our results indicate that PGW in patients with pancreatic duct diameter ≤ 3 mm increases the risk of PEP.

    Pancreatic adenocarcinomas and diabetes mellitus are responsible for the deaths of around two million people each year worldwide. Patients with chronic pancreatitis do not die directly of this disease, except where the pathology is hereditary. Much current literature supports the involvement of bile salt-dependent lipase (BSDL), also known as carboxyl ester lipase (CEL), in the pathophysiology of these pancreatic diseases. The purpose of this review is to shed light on connections between chronic pancreatitis, diabetes, and pancreatic adenocarcinomas by gaining an insight into BSDL and its variants. This enzyme is normally secreted by the exocrine pancreas, and is diverted within the intestinal lumen to participate in the hydrolysis of dietary lipids. However, BSDL is also expressed by other cells and tissues, where it participates in lipid homeostasis. Variants of BSDL resulting from germline and/or somatic mutations (nucleotide insertion/deletion or nonallelic homologous recombination) are expressed in the pancreas of patients with pancreatic pathologies such as chronic pancreatitis, MODY-8, and pancreatic adenocarcinomas. We discuss the possible link between the expression of BSDL variants and these dramatic pancreatic pathologies, putting forward the suggestion that BSDL and its variants are implicated in the cell lipid metabolism/reprogramming that leads to the dyslipidemia observed in chronic pancreatitis, MODY-8, and pancreatic adenocarcinomas. We also propose potential strategies for translation to therapeutic applications.

    The objective of this study was to investigate the value of low-dose whole pancreatic computed tomography (CT) perfusion integrated with individualized dual-energy CT (DECT) scanning in the diagnosis of pancreatic adenocarcinoma. Twenty patients with pancreatic adenocarcinoma underwent pancreatic CT perfusion as well as individualized dual-phase DECT pancreatic scans. Perfusion characteristics of non-tumourous pancreatic parenchyma and pancreatic adenocarcinoma were analysed. Weighted-average 120 kVp images and the optimal monoenergetic images in dual phase were reconstructed and the contrast noise ratio (CNR) of pancreas-to-tumour were compared. There were significant difference on blood flow as well as blood volume between pancreatic adenocarcinoma and the non-tumourous pancreatic parenchyma (P < 0.05), whereas no difference on permeability (P > 0.05). CNRs of pancreas-to-tumour in individualized pancreatic phase were significantly higher than those in venous phase (P < 0.05), and CNRs of optimal monoenergetic images were higher than those on weighted-average 120 kVp images (P < 0.05) in both phase. Total effective radiation dose of CT examination was around 9.32–13.75 mSv. Low-dose whole pancreatic CT perfusion can provide functional information, and the individualized pancreatic phase DECT scan is the optimal method for detecting pancreatic adenocarcinomas. The integration of the two techniques has great value in clinical application.

    Among late postoperative complications of pancreatectomy are the exocrine and endocrine pancreatic insufficiencies. The presence of exocrine pancreatic insufficiency imposes, as standard treatment, pancreatic enzyme replacement. Patients with chronic pancreatitis, with intractable pain or any complications with surgical treatment, are likely to present exocrine pancreatic insufficiency or have this condition worsened requiring adequate dose of pancreatic enzymes. The aim of this study is to compare the required dose of pancreatic enzyme and the enzyme replacement cost in post pancreatectomy patients with and without chronic pancreatitis. Observational cross-sectional study. In the first half of 2015 patients treated at the clinic of the Department of Gastrointestinal Surgery at Hospital das Clínicas, Universidade de São Paulo, Brazil, who underwent pancreatectomy for at least 6 months and in use of enzyme replacement therapy were included in this series. The study was approved by the Research Ethics Committee. The patients were divided into two groups according to the presence or absence of chronic pancreatitis prior to pancreatic surgery. For this study, Ptreatment was R$ 2150.5 ± 729.39; R$ 2118.18 ± 731.02 in patients without pancreatitis and R$ 2217.74 ± 736.30 in patients with pancreatitis. There was no statistically significant difference in the cost of treatment of enzyme replacement post pancreatectomy in patients with or without chronic pancreatitis prior to surgical indication.

  14. Role of autophagy in development and progression of acute pancreatitis

    Directory of Open Access Journals (Sweden)

    YANG Shuli

    2014-08-01

    Full Text Available Acute pancreatitis is considered an autodigestive disorder in which inappropriate activation of trypsinogen to trypsin within pancreatic acinar cells leads to the development of pancreatitis. Autophagy is an evolutionarily preserved degradation process of cytoplasmic cellular constituents, and it is one of the early pathological processes in acute pancreatitis. Autophagic flux is impaired in acute pancreatitis, which mediates the key pathologic responses of this disease. Impaired autophagy, dysfunction of lysosomes, and dysregulation of autophagy suggest a disorder of the endolysosomal pathway in acute pancreatitis. The role of autophagy in acute pancreatitis is discussed from the aspects of autophagic process, autophagy and activation of trypsinogen, impaired autophagy and acute pancreatitis, and defective autophagy promoting inflammation.

    During a 3-year-period 39 patients with chronic pancreatitis were subjected to roentgen examinations and exocrine pancreatic function tests (EPFT). Computer tomography (CT) was carried out in 36 of these, and revealed pancreatic disease in 29, while characteristic findings of chronic pancreatitis were demonstrated in 24 patients. CT was particularly valuable in diagnosing intra- and extrapancreatic pseudocysts and pancreatic abscesses complicating chronic pancreatitis. At endoscopic retrograde pancreatography (ERP) pathologic alterations were demonstrated in 23 of 24 patients, and was diagnostic for chronic pancreatitis in 20 patients. The cannulation failed in 7 patients. The results indicate that ERP cannot be replaced by CT. ERP is still needed for detailed demonstration of the pancreatic duct system, especially preoperatively. Conventional films of the abdomen, EPFT and angiography were the least sensitive tests. (Auth.)

    Pancreatic trauma treatment depends on pancreatic ductal injury. We examined the usefulness and problems of diagnostic imaging, such as enhanced CT, ERP, and CT after ERP, in pancreatic trauma. Subjects were 12 patients with pancreatic trauma treated in our hospital between April 1993 and March 2000. Enhanced CT was performed in 6 patients undergoing diagnostic imagings and ERP in 4 of the 6. Overall diagnostic accuracy of pancreatic ductal injury in enhanced CT was 16.7% and accuracy in ERP with CT after ERP was 100%. Intraoperative diagnosis of main pancreatic ductal injury was difficult in 1 of 2 patients in whom ERP failed. The importance of preoperative diagnostic imaging is thus clear. We expect that MRCP, recently evaluated in pancreatic disease diagnosis, will become a new pancreatic trauma modality. (author)

    Full Text Available Objective: to define a role of various maintenance modes, such as enteral tube feeding (ETF and complete parenteral feeding in different phases of acute pancreatitis (AP. Subjects and materials. The impact of various modes of nutritional support on pancreatic secretory activity and the course of AP was comparatively analyzed in 774 patients (mean age 45.3±4.7 years with AP. The criteria for evaluation of the activities of the pancreas and its inflammatory process activity were considered to be clinical and laboratory parameters (pain, body temperature, hemogram, amylasemia, the degree of dynamic ileus and abdominal inflammatory infiltrate, and the level of gastrointestinal peptides, and ultrasonographic and computed tomographic data. The additional impact of different types of protein-calorie provision on pancreatic secretory activity was studied in 23 patients with external pancreatic fistulas, by using debetometry. Results. ETF was shown to have a stimulating effect on pancreatic secretion and AP worsening when it was used in the early phases of the disease. The optimum time of complete parenteral feeding (days 5—14 after the onset of the disease and the criteria for the possible initiation of ETF were determined. Emphasis was laid on the important role of enteral feeding in a package of therapeutic measures in AP in the phase of pyonecrotic lesions. Conclusion. The proposed nutritional support tactics along with mini-invasive surgical treatments could reduce postoperative and overall mortality rates to 4.2 and 3.7%, respectively. Key words: acute pancreatitis, protein-calorie provision, nutritional support, enteral tube feeding, parenteral feeding, intestinal lavage, pancreatic secretion.

    Objective: To determine the specificity and sensitivity of plasma and urinary trypsinogen activation peptide (TAP) concentrat. Design: Retrospective analysis of clinical cases. Procedure: Dogs were classified into three groups: healthy animals, dogs with confirmed pancreatitis and dogs with nonpancreatic disease, which clinically or biochemically resembled pancreatitis. This last group was further subdivided into dogs with renal and those with nonrenal disease. The plasma and urinary TAP concentration was determined by a competitive enzyme immunoassay. Clinical cases additionally had serum trypsin-like immunoreactivity concentration measured, as well as radiography and ultrasound of the abdomen and further diagnostic procedures. Nonparametric analysis of variance (Kruskal-Wallis test) was performed using Statistix 4.0 program. Results: There was a wide range of urinary TAP concentration in healthy dogs (mean 52.30 nmol/L, standard deviation 55.25) that made interpretation of urinary TAP concentrations difficult in the other groups. There was a narrow reference range for plasma TAP (mean 2.67 nmol/L, standard deviation 0.93). Plasma and urinary TAP concentrations, as well as urinary TAP to creatinine ratio, were all increased in dogs that died with necrotising pancreatitis. Values were not increased in mild, interstitial pancreatitis. Increased plasma TAP concentrations were also present in dogs with severe renal disease. Conclusion: Plasma TAP concentration isa good prognostic indicator in naturally occurring pancreatitis in dogs. The failure of TAP to increase in mild pancreatitis, and the increase present in severe renal disease, suggests its measurement has limited application as a sole diagnostic tool for canine pancreatitis. Further investigations are required in order to explain the large variability of urinary TAP concentration and the presence of circulating TAP in healthy dogs

    Acute and chronic pancreatitis are becoming increasingly more severe diseases in the western world with far-reaching consequences for the individual patient as well as the socioeconomic situation. This article gives an overview of the contribution of radiological imaging to the diagnostics and therapy of both forms of the disease. Acute pancreatitis can be subdivided into severe (20 %) and mild manifestations. The diagnostics should be performed with computed tomography (CT) or magnetic resonance imaging (MRI) for assessing necrosis or potential infections only in severe forms of pancreatitis. In chronic pancreatitis transabdominal ultrasound should initially be adequate for assessment of the pancreas. For the differential diagnosis between pancreatic carcinoma and chronic pancreatitis, MRI with magnetic resonance cholangiopancreatography (MRCP) followed by an endoscopic ultrasound-guided fine needle aspiration is the method of choice. For the primary diagnosis for acute and chronic pancreatitis ultrasound examination is the modality of first choice followed by radiological CT and MRI with MRCP examinations. (orig.) [German] Akute und chronische Pankreatitis sind in der westlichen Welt zunehmende schwere Krankheitsbilder mit tiefgreifenden Konsequenzen fuer den einzelnen Patienten sowie soziooekonomisch.

Die akute Pankreatitis kann in eine schwere (20 %) und milde Verlaufsform unterteilt werden. Lediglich bei den schweren Formen sollte eine CT- oder MRT-Diagnostik bzgl. der Beurteilung von Nekrosen und moeglichen Infektionen erfolgen. Bei der chronischen Pankreatitis genuegt zunaechst eine Beurteilung des Pankreas durch transabdominellen Ultraschall.

    Full Text Available Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptors, platelet-derived growth factor receptors, and c-Kit approved for the treatment of renal cell carcinoma and soft tissue sarcoma. Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopanib treatment for cutaneous angiosarcoma. The patient was an 82-year-old female diagnosed with cutaneous angiosarcoma. She had been refractory to docetaxel treatment and began pazopanib therapy. Three months after pazopanib treatment, CT imaging of the abdomen showed the swelling of the pancreas and surrounding soft tissue inflammation without abdominal pain. After she continued pazopanib treatment for 2 months, she presented with nausea and appetite loss. Abdominal CT showed the worsening of the surrounding soft tissue inflammation of the pancreas. Serum amylase and lipase levels were 296 and 177 IU/l, respectively. She was diagnosed with acute pancreatitis induced by pazopanib treatment and was managed conservatively with discontinuation of pazopanib, but the symptoms did not improve. Subsequently, an abdominal CT scan demonstrated the appearance of a pancreatic pseudocyst. She underwent endoscopic ultrasound-guided pseudocyst drainage using a flared-end fully covered self-expandable metallic stent. Then, the symptoms resolved without recurrence. Due to the remarkable progress of molecular targeted therapy, the oncologist should know that acute pancreatitis was recognized as a potential adverse event of pazopanib treatment and could proceed to severe acute pancreatitis.

    There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma. Carbohydrate antigen 19-9 (CA 19-9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up. One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis. In this study we will assess the value of panels of serum molecules related to pancreatic cancer physiopathology to determine whether alone or in combination could help to discriminate between these two pathologies. CA 19-9, carcinoembryonic antigen (CEA), C-reactive protein, albumin, insulin growth factor-1 (IGF-1) and IGF binding protein-3 were measured using routine clinical analyzers in a cohort of 47 pancreatic adenocarcinoma, 20 chronic pancreatitis and 15 healthy controls. The combination of CA 19-9, IGF-1 and albumin resulted in a combined area under the curve (AUC) of 0.959 with 93.6% sensitivity and 95% specificity, much higher than CA 19-9 alone. An algorithm was defined to classify the patients as chronic pancreatitis or pancreatic cancer with the above specificity and sensitivity. In an independent validation group of 20 pancreatic adenocarcinoma and 13 chronic pancreatitis patients, the combination of the four molecules classified correctly all pancreatic adenocarcinoma and 12 out of 13 chronic pancreatitis patients. Although this panel of markers should be validated in larger cohorts, the high sensitivity and specificity values and the convenience to measure these parameters in clinical laboratories shows great promise for improving pancreatic adenocarcinoma diagnosis.

    Objective: To compare serum lipase and amylase activity levels in patients with tuberculosis (TB against those of healthy controls. Methods: Serum lipase and amylase activity levels were measured in 99 patients and 143 healthy controls using the Vitros 250 Chemistry analyser. Reference ranges for serum lipase and amylase were 23–300 U/L and 30–110 U/L, respectively. Results: Lipase was higher in patients with MTB than in controls (81.5 IU/L versus 66.5 IU/L, p = 0.006. Similarly, amylase was higher in the MTB patient group (76 IU/L versus 60 IU/L, p < 0.001. The Pearson correlation coefficient for lipase versus amylase (R was higher in the controls (R = 0.351, p < 0.0001 compared with MTB patients (R = 0.217, p = 0.035. Amongst MTB patients, lipase activity correlated positively with erythrocyte sedimentation rate (ESR (R = 0.263, p = 0.013, but not with haemoglobin concentration or treatment duration. A weak inverse correlation was noted between ESR and treatment duration (R = -0.222, p = 0.028. Conclusion: Pancreatic enzyme levels differ between MTB patients and normal controls; however, this difference still lies within the normal range. The concomitant increase of lipase with ESR, an inflammatory marker, could conceivably suggest a causal relationship. Further research is necessary to characterise MTB-derived enzymes for diagnostic and therapeutic utility.

    Full Text Available Pegaspargase is used to treat acute lymphocytic leukemia (ALL. Pegaspargase definitely has its benefits in treating ALL; however we cannot lose sight of one of its very rare but potentially deadly complications, acute pancreatitis. Clinicians should monitor triglycerides while the patient is on treatment with Pegaspargase and suspect acute pancreatitis if the patient develops abdominal pain. If pancreatitis occurs, therapy should be stopped immediately and not reinstituted. For patients with hypertriglyceridemia without pancreatitis, discontinuation of therapy should be considered.

    Patients could develop endocrine and exocrine pancreatic insufficiency after acute pancreatitis (AP), but the morbidity, risk factors and outcome remain unclear. The aim of the present study was to evaluate the incidence of endocrine and exocrine pancreatic insufficiency after AP and the risk factors of endocrine pancreatic insufficiency through a long-term follow-up investigation. Follow-up assessment of the endocrine and exocrine function was conducted for the discharged patients with AP episodes. Oral Glucose Tolerance Test (OGTT) and faecal elastase-1(FE-1) test were used as primary parameters. Fasting blood-glucose (FBG), fasting insulin (FINS), glycosylated hemoglobin HBA1c, 2-h postprandial blood glucose (2hPG), Homa beta cell function index (HOMA-β), homeostasis model assessment of insulin resistance (HOMA-IR) and FE-1 were collected. Abdominal contrast-enhanced computed tomography (CECT) was performed to investigate the pancreatic morphology and the other related data during hospitalization was also collected. One hundred thirteen patients were included in this study and 34 of whom (30.1%) developed diabetes mellitus (DM), 33 (29.2%) suffered impaired glucose tolerance (IGT). Moreover, 33 patients (29.2%) developed mild to moderate exocrine pancreatic insufficiency with 100μg/gpancreatic insufficiency with FE-1pancreatic necrosis was significant higher than that in the non-pancreatic necrosis group (X 2  = 13.442,P = 0.001).

HOMA-IR (P = 0.002, OR = 6.626), Wall-off necrosis (WON) (P = 0.013, OR = 184.772) were the risk factors. The integrated morbidity of DM and IGT after AP was 59.25%, which was higher than exocrine pancreatic insufficiency. 6.2% and 29.2% of patients developed severe and mild to moderate exocrine pancreatic insufficiency, respectively. The extent of pancreatic necrosis>50%, WON and insulin resistance were

    This research study sought to improve the treatment of pancreatic cancer by improving the drug delivery of a promising AKT/PDK1 inhibitor, PHT-427, in poly(lactic-co-glycolic) acid (PLGA) nanoparticles. PHT-427 was encapsulated in single-emulsion and double-emulsion PLGA nanoparticles (SE-PLGA-427 and DE-PLGA-427). The drug release rate was evaluated to assess the effect of the second PLGA layer of DE-PLGA-427. Ex vivo cryo-imaging and drug extraction from ex vivo organs was used to assess the whole-body biodistribution in an orthotopic model of MIA PaCa-2 pancreatic cancer. Anatomical magnetic resonance imaging (MRI) was used to noninvasively assess the effects of 4 weeks of nanoparticle drug treatment on tumor size, and diffusion-weighted MRI longitudinally assessed changes in tumor cellularity. DE-PLGA-427 showed delayed drug release and longer drug retention in the pancreas relative to SE-PLGA-427. Diffusion-weighted MRI indicated a consistent decrease in cellularity during drug treatment with both types of drug-loaded nanoparticles. Both SE- and DE-PLGA-427 showed a 6-fold and 4-fold reduction in tumor volume relative to untreated tumors and an elimination of primary pancreatic tumor in 68% of the mice. These results indicated that the PLGA nanoparticles improved drug delivery of PHT-427 to pancreatic tumors, which improved the treatment of MIA PaCa-2 pancreatic cancer.

    Full Text Available Hypertriglyceridemia is a rare cause of pancreatitis. In treatment pancreatic rest, lifestyle changes, medications (fibrates, n-3 polyunsaturated fatty acids, and nicotinic acid are essential. Many experimental treatment modalities have been reported as insulin and heparin infusion and plasmapheresis. In this study we present the hypertriglyceridemia-induced pancreatitis treated with supportive care.

    We examined 20 prediagnostic CTs from 16 patients for whom the diagnosis of pancreatic cancer was delayed until full diagnostic CT was performed. Three radiologists independently reviewed the prediagnostic CTs along with 50 CTs of control subjects, including patients without pancreatic disease (n = 38) or with chronic pancreatitis without calcification visible on CT (n=12). The reviewers recorded the presence of biliary or pancreatic ductal dilation, interruption of the pancreatic duct, distal parenchymal atrophy, contour abnormality and focal hypoattenuation. Frequency, sensitivity and specificity of the significant findings were calculated. Logistic regression analysis was performed. Findings indicative of pancreatic cancer were seen on 85% (17/20) of the prediagnostic CTs. Patients with pancreatic cancer were significantly (p<0.05) more likely to show focal hypoattenuation, pancreatic duct dilation, interruption of the pancreatic duct, and distal parenchymal atrophy, with sensitivities and specificities of 75%/84%, 50%/78%, 45%/82% and 45%/96%, respectively. Focal hypoattenuation and distal parenchymal atrophy were the independent predictors of pancreatic cancer with odds ratios of 20.92 and 11.22, respectively. In conclusion, focal hypoattenuation and pancreatic duct dilation with or without interruption, especially when accompanied by distal parenchymal atrophy, were the most useful findings for avoiding delayed diagnosis of pancreatic cancer.

    Acute pancreatitis is the leading cause of acute hospitalization for gastrointestinal diseases. The course of acute pancreatitis is often mild and self-limiting, but in 15-25% of patients, pancreatitis is severe with an increased mortality risk. Infectious complications, and especially bacterial

    Conclusions: Estimating serum calcium after an episode of unexplained pancreatitis is important and can help minimize delay in diagnosing primary hyperparathyroidism, and possibly prevent the progression of pancreatitis. Parathyroidectomy improves the clinical outcome of primary hyperparathyroidism and prevents further attacks of pancreatitis.

    Neither goblet cells nor ductal glands were found in the pancreatic ducts. Secretion of both neutral and sulfated materials by the epithelial lining the pancreatic ducts, suggesting that they are acting not only to facilitate the transport of the pancreatic juice, but also as a protective barrier to protect the gland from autodigestion.
