Abstract
This research aimed to assess the effect of pharmacotherapy alone versus the combination of pharmacotherapy and endoscopic stenting on the quality of life (QoL) outcomes of chronic pancreatitis patients. Chronic pancreatitis, an inflammatory disease, often presents with persistent pain, affecting patients' quality of life. Thirty patients treated either with pharmacotherapy alone or with the addition of endoscopic stenting were analyzed. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) was used to gather data on the patients' QoL. Results showed that both treatment groups experienced improvements in global health, role functioning, fatigue, and abdominal pain scores over follow-ups. Specifically, the stenting group saw notable enhancements in global health and role functioning. The study's conclusions provide valuable insights into the potential benefits of both treatments, with stenting offering significant improvements in certain QoL parameters. However, the sample size and source limit generalizability, suggesting the need for more extensive research across diverse settings.

Abstract
Pancreatitis is a debilitating disease involving inflammation and fibrosis of the exocrine pancreas. Recurrent or chronic forms of pancreatitis are a significant risk factor for pancreatic ductal adenocarcinoma. While genetic factors have been identified for both pathologies, environmental stresses play a large role in their etiology. All cells have adapted mechanisms to handle acute environmental stress that alters energy demands. A common pathway involved in the stress response involves endoplasmic reticulum stress and the unfolded protein response (UPR). While rapidly activated by many external stressors, in the pancreas the UPR plays a fundamental biological role, likely due to the high protein demands in acinar cells. Despite this, increased UPR activity is observed in response to acute injury or following exposure to risk factors associated with pancreatitis and pancreatic cancer. Studies in animal and cell cultures models show the importance of affecting the UPR in the context of both diseases, and inhibitors have been developed for several specific mediators of the UPR. Given the importance of the UPR to normal acinar cell function, efforts to affect the UPR in the context of disease must be able to specifically target pathology vs. physiology. In this review, we highlight the importance of the UPR to normal and pathological conditions of the exocrine pancreas. We discuss recent studies suggesting the UPR may be involved in the initiation and progression of pancreatitis and PDAC, as well as contributing to chemoresistance that occurs in pancreatic cancer. Finally, we discuss the potential of targeting the UPR for treatment.

Abstract
BACKGROUND The exocrine function of the pancreas is controlled by the autonomic nervous system (ANS), and autonomic neuropathy is a common and serious complication of diabetes. There are many factors contributing to the development of autonomic neuropathy in diabetic patients. Cardiovascular tests have been developed to evaluate the function of the ANS. This study investigated the relationship between cardiovascular autonomic neuropathy (CAN) and pancreas exocrine insufficiency (PEI) in diabetic patients. METHODS This study evaluated 110 individuals with type 2 diabetes mellitus (T2DM) and 40 healthy volunteers. Autonomous neuropathy tests were utilized to diagnose patients, and Ewing and Clarke's criteria were employed to assess the severity of autonomous dysfunction. Stool samples were also collected from patients to measure fecal elastase-1 (FE-1). RESULTS A 65.5% incidence of PEI was observed in DM patients. There was no significant correlation among the duration of disease, C-peptide, HbA1c, and PEI, respectively (P = .782, P = .521, P = .580). However, a significant difference between DM patients and controls in terms of cardiac dysautonomia (P = .001) was seen. Moreover, a statistically significant correlation between the degree of cardiac dysautonomia and FE-1 level was observed within the patient group (P =.001). CONCLUSION It is possible that the disruption of exocrine hormone secretion in the pancreas due to the impairment of enteropancreatic reflexes is secondary to diabetic autonomic neuropathy and resulting in PEI. This study also showed that autonomic neuropathy might develop and cause PEI in diabetic patients without known added confounding factors.

Abstract
Exocrine pancreatic insufficiency (EPI) is defined as the maldigestion of foods due to inadequate pancreatic secretion, which can be caused by alterations in its stimulation, production, transport, or interaction with nutrients at duodenal level. The most frequent causes are chronic pancreatitis in adults and cystic fibrosis in children. The prevalence of EPI is high, varying according to its etiology, but it is considered to be underdiagnosed and undertreated. Its importance lies in the quality of life impairment that results from the malabsorption and malnutrition and in the increased morbidity and mortality, being associated with osteoporosis and cardiovascular events. The diagnosis is based on a set of symptoms, indicators of malnutrition, and an indirect non-invasive test in at-risk patients. The treatment of choice combines non-restrictive dietary measures with pancreatic enzyme replacement therapy to correct the associated symptoms and improve the nutritional status of patients. Non-responders require the adjustment of pancreatic enzyme therapy, the association of proton pump inhibitors, and/or the evaluation of alternative diagnoses such as bacterial overgrowth. This review offers an in-depth overview of EPI in order to support the proper management of this entity based on updated and integrated knowledge of its etiopathogenesis, prevalence, diagnosis, and treatment.

Abstract
Pancreatic islet transplantation is a reliable approach for treating insulin-deficient diabetes. This established β-cell replacement approach has shown considerable improvements in the last 2 decades. It has helped achieve metabolic homeostasis and safe outcomes for a subset of patients with type 1 diabetes and severe pancreatitis. Nutrition support, until recently, was considered as a secondary factor, merely identified as a means of providing all the necessary nutrients for such patients. However, new literature suggests that several factors, such as the route, timing, quantity, and composition of all the nutrients administered, have key disease-altering properties and are vital during the perioperative management of such patients. This review will highlight the benefits of performing the clinical islet transplantation on a subgroup of patients with type 1 diabetes and pancreatitis and summarize new data that identify the pivotal role of nutrition support as a critical intervention in their management.

Abstract
Background: Exocrine pancreatic insufficiency results from the destruction of the pancreatic parenchyma and is diagnosed by using direct or indirect tests, both of which have shortcomings. Chronic pancreatitis is the most frequent cause of this pathology in adults. Methods: Patients meeting radiological or histological diagnostic criteria of chronic pancreatitis are enrolled and the stool elastase test is conducted, considering fecal elastase levels >200 µg/g to represent normal pancreatic function, and levels <200 μg/g to indicate the presence of exocrine pancreatic insufficiency. Additionally, we determine the body mass index of the patients and study their nutritional status and main biochemical and hematological variables, including their glucose and hemoglobin A1c (HbA1c) levels. Results: Exocrine pancreatic insufficiency is detected in 60% of the patients. Among these, 83.3% are severe cases, and 72% of the latter also are diagnosed with endocrine pancreatic insufficiency (diabetes mellitus). During the nutritional status study, HbA1c levels are significantly higher, and magnesium and prealbumin levels are significantly lower in patients with exocrine pancreatic insufficiency than in those without this disease. Conclusions: Exocrine and endocrine pancreatic insufficiency are highly prevalent among patients with chronic pancreatitis and an early diagnosis of these diseases is vital to improve the clinical management of these patients and reduce their risk of mortality.

Abstract
OBJECTIVES Pancreatic exocrine insufficiency (PEI) is a common complication of chronic pancreatitis. However, little is known about the natural course of PEI and the effect of pancreatic enzyme replacement therapy on symptoms. The aim of this study was to evaluate the natural course and treatment of PEI in a nationwide cohort of patients with chronic pancreatitis. METHODS Patients with chronic pancreatitis were selected from the multicenter Dutch Chronic Pancreatitis Registry. Patients were classified in 3 groups: definite PEI, potential PEI, and no PEI. Definite PEI and no PEI were compared regarding the course of disease, symptoms, treatment, and quality of life. RESULTS Nine hundred eighty-seven patients were included from 29 centers, of which 304 patients (31%) had definite PEI; 451 (46%), potentially PEI; and 232 (24%), no PEI. Patients with definite PEI had significantly more malabsorption symptoms, a lower body mass index, and aberrant defecation. Lowered quality of life was not independently associated with PEI. Of the PEI patients using pancreatic enzyme replacement therapy, 47% still reported steatorrhea. CONCLUSIONS Pancreatic exocrine insufficiency is associated with malabsorption symptoms and a lower body mass index. Some form of pancreatic enzyme replacement therapy is reasonably effective in alleviating malabsorption symptoms, but improvement of treatment is needed.

Abstract
INTRODUCTION We assessed whether positive microbiological cultures from the islet preparation had any effect on the risk of infectious complications (IC) after total pancreatectomy with islet autotransplantation (TPIAT) in our center. METHODS We analyzed preservation fluid and final islet product surveillance cultures with reference to clinical data of patients undergoing TPIAT. All patients received routine prophylactic broad-spectrum antibiotics. RESULTS The study involved 10 men and 18 women with a median age of 39 years. Over 30% of surveillance cultures during pancreas processing grew bacterial strains with predominantly polymicrobial contaminations (13 of 22 (59%)). At least one positive culture was identified in almost half of the patients (46%) undergoing TPIAT and a third had both surveillance cultures positive. Infectious complications affected 50% of patients. After excluding cases of PICC line-associated bacteremia/fungemia present on admission, incidence of IC was higher in cases of positive final islet product culture than in those with negative result (57% vs. 21%), which also corresponded with the duration of chronic pancreatitis (p = 0.04). Surgical site infections were the most common IC, followed by fever of unknown origin. There was no concordance between pathogens isolated from the pancreas and those identified during the infection. CONCLUSIONS While IC was common among TPIAT patients, we found no concordance between pathogens isolated from the pancreas and those identified during infection. Contamination of the final islet product was of clinical importance and could represent a surrogate marker for higher susceptibility to infection.

Abstract
We describe the rational use of enteric coated and unprotected replacement pancreatic enzymes for treatment of malabsorption due to pancreatic insufficiency and for pancreatic pain. Enteric coated formulations mix poorly with food allowing separation of enzymes and nutrients when emptying from the stomach. The site of dissolution of the enteric coating in the intestine is also unpredictable and enzymes may not be released until the distal intestine. Together, these barriers result in the lack of dose-response such that the strategy of increasing the dosage following a suboptimal effect is often ineffective. The ability to maintain the intragastric pH ≥4 with the combination of proton pump inhibitors and antacids suggests that it should be possible to reliably obtain a good response with uncoated enzymes. We also discuss the recognition, treatment and prevention of nutritional deficiencies associated with pancreatic insufficiency and recommend a test and treat strategy to identify and resolve nutritional deficits. Finally, we focus on mechanisms causing pain that may be amenable to therapy with pancreatic enzymes. Pain due to malabsorbed digestive contents can be prevented by successful therapy of malabsorption. Feedback inhibition of endogenous pancreatic secretion can prevent pain associated with pancreatic secretion but requires use of non-enteric coated formulations.

Abstract
OBJECTIVES Reliable pancreatic function tests in patients with chronic pancreatitis (CP) are needed. This cohort study identified malabsorption in people with CP compared with healthy people and then investigated short-term pancreatic enzyme replacement therapy (PERT) and fat malabsorption, nutritional status, and quality of life (QOL). METHODS Subjects with CP were evaluated before and after PERT and compared with the healthy cohort using coefficient of fat absorption (CFA), stool bomb calorimetry, and the malabsorption blood test (MBT). Anthropometrics, micronutrients, and QOL data were collected. Group means at baseline and after PERT were analyzed. RESULTS The 24 subjects with CP had greater stool energy loss (5668 cal/g [standard deviation {SD}, 753] vs 5152 cal/g [SD, 418], P < 0.01), reduced triglyceride absorption (MBT, 8.3 mg·h/dL [SD, 4.3] vs 17.7 mg·h/dL [SD, 10.3], P < 0.001), lower fat intake, and poorer QOL. Differences in CFA were not significant (90.9% [SD, 12.8] vs 95.4% [SD, 9.3]). After PERT, triglyceride absorption (Δ = 1.7 [SD, 3], P < 0.05) and QOL increased. CONCLUSIONS The MBT detected changes in triglyceride absorption in the absence of CFA changes. The MBT may be helpful in guiding PERT initiation in patients with CP before significant morbidity.

Does the Healthy Eating Index and Mediterranean Diet Score Identify the Nutritional Adequacy of Dietary Patterns in Chronic Pancreatitis? Dig Dis Sci 2019; 64:2318-2326. [PMID: 30798461 DOI: 10.1007/s10620-019-05536-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2018] [Accepted: 02/14/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Chronic pancreatitis (CP) is a progressive, irreversible disease characterized by maldigestion and frequently accompanied by epigastric pain, exocrine insufficiency, and/or endocrine insufficiency. There is limited information about the dietary patterns in CP from which to guide medical nutrition therapy recommendations. METHODS Study design was a cross-sectional, case-control study comparing subjects with CP (n = 52) to healthy controls (n = 48). Vioscreen™ food frequency questionnaire was used to assess the dietary pattern and nutrient intake in both groups. Dietary quality scores (the Healthy Eating Index, Mediterranean Diet score), and daily energy, macronutrient, and micronutrient intake levels were compared between groups. ANALYSIS Two sample t tests and Wilcoxon rank sum tests were used to evaluate differences in continuous variables, and Chi-squared tests were used for categorical variables. RESULTS CP was associated with a lower body mass index (BMI) (24 vs. 31 mg/kg2; p < 0.001), lower HEI (57 vs. 65; p = 0.002), and aMED scores (29 vs. 32; p = 0.043) compared to healthy controls. Subjects with CP in the highest BMI quartile had the highest median aMED score compared to those in the lowest BMI quartile. There were no differences in kilocalories, macronutrients, or fat-soluble vitamin intake between groups, with the exception that vitamin K intake was lower in the CP group. CONCLUSIONS The overall quality of dietary intake is lower in subjects with CP compared to controls when assessed by two independent nutritional measurement tools. Further research is needed to examine contributing factors, such as food insecurity and coexisting endocrine or exocrine insufficiency, to dietary patterns in patients with CP from which to guide evidence-based recommendations for medical nutritional therapy.

Abstract
Purpose Pancreatitis can lead to systemic inflammatory response, but the relationship between lymphocyte changes and patients with pancreatitis remains unclear. In this study, we evaluated the feedback function of changes in peripheral lymphocyte subsets on the condition of patients with pancreatitis. Materials and Methods 131 acute pancreatitis (AP) patients and 11 chronic pancreatitis (CP) patients constituted the patients' group; 20 healthy individuals were enrolled as healthy controls (HC). Serum concentration of C-reactive protein (CRP), amylase, and lipase and the frequency and absolute number of many types of peripheral lymphocytes (including T, B, NK, CD16+/CD56+ T, CD4+ T, CD8+ T, CD4+CD8+ T, and CD4−CD8− T cells) were detected on admission and the seventh day of standard treatment. Besides, the length of hospital stay was recorded. Results The absolute number of all lymphocytes we studied decreased in patients with CP and in patients with almost all types of AP. The frequency change of lymphocytes varies among the different types of AP. During disease onset, B cell frequency correlated positively with CRP concentration and NK cell frequency correlated positively with amylase and lipase concentration. B cell frequency and CD4+ T cell absolute number were recovering towards normal after short-term treatment. The frequency of B cells and NK cells correlated positively with the length of hospital stay. Conclusions B cells and NK cells closely correlate with patients' condition and may help to diagnose AP more accurately and reflect treatment effect of AP in time, affecting the recovery speed of patients with M-AP, which may help physicians to better understand the pathophysiology of pancreatitis.

Abstract
BACKGROUND Chronic pancreatitis (CP) can lead to severe pancreatic exocrine insufficiency (PEI). Pancreatic enzyme replacement therapy (PERT) is well established, but knowledge of the physiological response to increasing doses on fecal fat- and energy loss is scarce. METHODS We included 10 patients with CP and established PEI and 12 healthy controls for a prospective interventional study. Subjects received no PERT in the first week followed by four weeks PERT incrementally increasing doses every week. For each week, three-day stool collection followed three days registration of nutritional intake. We measured the fecal output of fat and energy by van de Kamer titration and decomposition vessel calorimetry, respectively. We calculated fecal fat- and energy loss per day, the coefficient of fat absorption (CFA) and coefficient of energy absorption (CEA). RESULTS Without PERT treatment, CP patients with PEI had significantly higher daily fecal fat and energy loss (p = .022; p = .035) compared to HC. In CP patients, there was a significant reduction of fecal fat and energy loss (p = .045; p = .037) when PERT doses reached maximum intake of 75,000 units per meal. In CP patients, there was a strong positive correlation between fecal loss of energy and fat (r = 0.99), and between fecal loss of energy and daily stool weight (r = 0.97). CFA and CEA correlated negatively with daily fecal fat loss (r = -0.72) and fecal energy loss (r = -0.65). CONCLUSIONS PERT reduces fecal energy and fat loss in patients with CP and PEI. Fecal energy loss in CP patients is strongly dependent on fecal fat loss, and on fecal weight.

Abstract
BACKGROUND The optimal nutritional therapy in the field of pancreatic surgery is still debated. METHODS An international panel of recognized pancreatic surgeons and pancreatologists decided that the topic of nutritional support was of importance in pancreatic surgery. Thus, they reviewed the best contemporary literature and worked to develop a position paper to provide evidence supporting the integration of appropriate nutritional support into the overall management of patients undergoing pancreatic resection. Strength of recommendation and quality of evidence were based on the approach of the grading of recommendations assessment, development and evaluation Working Group. RESULTS The measurement of nutritional status should be part of routine preoperative assessment because malnutrition is a recognized risk factor for surgery-related complications. In addition to patient's weight loss and body mass index, measurement of sarcopenia and sarcopenic obesity should be considered in the preoperative evaluation because they are strong predictors of poor short-term and long-term outcomes. The available data do not show any definitive nutritional advantages for one specific type of gastrointestinal reconstruction technique after pancreatoduodenectomy over the others. Postoperative early resumption of oral intake is safe and should be encouraged within enhanced recovery protocols, but in the case of severe postoperative complications or poor tolerance of oral food after the operation, supplementary artificial nutrition should be started at once. At present, there is not enough evidence to show the benefit of avoiding oral intake in clinically stable patients who are complicated by a clinically irrelevant postoperative pancreatic fistula (a so-called biochemical leak), while special caution should be given to feeding patients with clinically relevant postoperative pancreatic fistula orally. When an artificial nutritional support is needed, enteral nutrition is preferred whenever possible over parenteral nutrition. After the operation, regardless of the type of pancreatic resection or technique of reconstruction, patients should be monitored carefully to assess for the presence of endocrine and exocrine pancreatic insufficiency. Although fecal elastase-1 is the most readily available clinical test for detection of pancreatic exocrine insufficiency, its sensitivity and specificity are low. Pancreatic enzyme replacement therapy should be initiated routinely after pancreatoduodenectomy and in patients with locally advanced disease and continued for at least 6 months after surgery, because untreated pancreatic exocrine insufficiency may result in severe nutritional derangement. CONCLUSION The importance of this position paper is the consensus reached on the topic. Concentrating on nutritional support and therapy is of utmost value in pancreatic surgery for both short- and long-term outcomes.

Abstract
OBJECTIVES Wide variations exist in how physicians manage the nutritional aspects of children affected by acute pancreatitis (AP), acute recurrent pancreatitis (ARP), and chronic (CP) pancreatitis. Better consensus for optimal management is needed. METHODS This consensus statement on nutrition in pediatric pancreatic diseases was developed through a joint ESPGHAN-NASPGHAN working group that performed an evidence-based search of the literature on nutrition in AP, ARP, and CP with a focus on pediatrics. The literature was summarized, quality of evidence reviewed, and expert recommendations developed. The authorship met to discuss the evidence and statements. Voting on recommendations occurred over 2 rounds based on feedback. A consensus of at least 75% was required to approve a recommendation. Areas requiring further research were identified. RESULTS AND DISCUSSION The literature on nutrition in pediatric pancreatitis is limited. Children with mild AP benefit from starting an early nutritional regimen in the course of the attack. Early nutrition should be attempted in severe AP when possible; enteral nutrition is preferred over parenteral nutrition. Children with ARP are likely to tolerate and benefit from a regular diet. Children with CP need ongoing assessment for growth and nutritional deficiencies, exocrine and endocrine insufficiencies. CONCLUSIONS This document presents the first authoritative recommendations on nutritional considerations in pediatric pancreatitis. Future research should address the gaps in knowledge particularly relating to optimal nutrition for AP in children, role of diet or dietary supplements on recurrent attacks of pancreatitis and pain episodes, monitoring practices to detect early growth and nutritional deficiencies in CP and identifying risk factors that predispose children to these deficiencies.

Abstract
INTRODUCTION Visceral adipose tissue (VAT) is a risk factor for diabetes and we investigated the amount of VAT in patients with chronic pancreatitis (CP). METHODS Serial patients with CP seen between January 2015 and June 2016 were included in this cross-sectional, observational study. The study population was divided into alcoholic CP (group 1; N = 67) and tropical CP (group 2; N = 35). VAT was estimated using bioelectric impedance analysis (BIA) and dual energy X-ray absorptiometry (DEXA) methods. The results were analyzed by appropriate statistical methods. RESULTS The study participants (85 male, 17 female) had a mean (SD) age of 40.8 (12.6) years, CP duration of 3.7 (4.7) years, and body mass index of 22.5 (3.2) kg/m2. Pancreatogenic diabetes was seen in 54 patients and the total body fat percentage was lower in the alcoholic CP group. VAT mass was similar in both the groups (p = 0.8749). CP patients with diabetes had a higher VAT mass (436 vs. 341 g) than those without diabetes (p = 0.0132). DEXA and BIA correlated in estimation of total body fat (p < 0.0001) but not in VAT (p = 0.0922). CONCLUSION VAT is a determinant in the development of diabetes, even in patients with CP. DEXA is a better modality for VAT estimation in comparison to BIA.

Diagnosis of exocrine pancreatic insufficiency in chronic pancreatitis: 13C-Mixed Triglyceride Breath Test versus Fecal Elastase. Pancreatology 2017; 17:580-585. [PMID: 28291656 DOI: 10.1016/j.pan.2017.03.002] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2017] [Revised: 03/01/2017] [Accepted: 03/05/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Pancreatic enzyme replacement therapy (PERT) is indicated in case of clinically relevant exocrine pancreatic insufficiency (EPI). Clinical trials addressing PERT have used the coefficient of fat absorption (CFA) to define EPI but this test is cumbersome to perform. Our aim was to compare two easier-to-perform tests to detect clinically relevant EPI: Fecal Elastase-1 (FE-1) and 13C-Mixed Triglyceride Breath Test (TGBT). METHODS We prospectively included 54 patients with chronic pancreatitis (CP), 24.1% operated, 29.6% had EPI. EPI was defined as a CFA <93%. The sensitivity (Se), specificity (Sp), positive (PPV) and negative (NPV) predictive values for different cut-offs of FE-1 and TGBT were calculated. RESULTS The area under the ROC curve for FE-1/TGBT was 0.861/0.876 for the global sample, 0.842/0.794 for non-operated patients and 0.917/1 for operated patients respectively. Se, Sp, PPV and NPV for a cut-off of FE-1 <200 μg/g were 93.8%, 63.2%, 51.7% and 96% respectively. The best cut-off point for FE-1 was 84 μg/g, which yielded an 87.5% Se, 81.6% Sp, 66.7% PPV and 93.9% NPV. The same parameters for a TGBT <29% were 81.3%, 84.2%, 68.4% and 91.4% respectively. The best cut-off point for TGBT was <23%, which yielded an 81.3% Se, 94.7% Sp, 86.7% PPV and 92.3% NPV. Diabetes was associated to decreased FE-1 levels, even in multivariate analysis. CONCLUSIONS FE-1 and TGBT showed similar results for the diagnosis of EPI in CP. In non-operated CP patients, TGBT does not offer any advantage to FE-1 but in operated CP patients TGBT seems a more accurate test.

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

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

Abstract
Typical clinical symptoms of chronic pancreatitis are vague and non-specific and therefore diagnostic tests are required, none of which provide absolute diagnostic certainly, especially in the early stages of disease. Recently-published guidelines bring much needed structure to the diagnostic work-up of patients with suspected chronic pancreatitis. In addition, novel diagnostic modalities bring promise for the future. The assessment and diagnosis of pancreatic exocrine insufficiency remains challenging and this review contests the accepted perspective that steatorrhea only occurs with > 90% destruction of the gland.

Preclinical pharmacokinetic, biodistribution, imaging and therapeutic efficacy of (177)Lu-Labeled glycated bombesin analogue for gastrin-releasing peptide receptor-positive prostate tumor targeting. Nucl Med Biol 2014; 42:234-41. [PMID: 25498002 DOI: 10.1016/j.nucmedbio.2014.10.008] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2014] [Revised: 10/14/2014] [Accepted: 10/15/2014] [Indexed: 10/24/2022]
Abstract
UNLABELLED The gastrin-releasing peptide receptor (GRPR) has been shown to be overexpressed in many human tumors, including prostate, colon, gastric, breast, pancreatic, and small cell lung cancers. Because bombesin (BBS) binds to GRPR with high affinity, BBS derivatives have been labeled with various radionuclides and have been demonstrated to be successful candidates for peptide receptor radiotherapy (PRRT). The present study describes the in vitro and in vivo preclinical characteristics of (177)Lu-DOTA-Lys(glucose)-4 aminobenzoic acid-BBS7-14 ((177)Lu-DOTA-gluBBN) to prepare radiolabeled candidates for the treatment of GRPR-expressing prostate tumors. METHODS (177)Lu-DOTA-gluBBN was prepared as previously published [1]. Human prostate PC-3 tumor cells were used to determine the binding (Kd) retention and efflux of (177)Lu-DOTA-gluBBN. Pharmacokinetic, imaging, and radiotherapy studies were performed in PC-3 xenografted mice. RESULTS The Kd value of (177)Lu-DOTA-gluBBN was 0.63 nM, with a maximum binding capacity (Bmax) of 669.7 fmol/10(6) cells (4.04×10(5) GRPR/cell). During a 2-hr incubation, 90.1±0.4% of the cell-associated radio-peptide was internalized, and 56.3±7.1% of the internalized radio-peptide was externalized in vitro. High amounts of the radio-peptide were rapidly accumulated in a PC-3 tumor in vivo, and the % ID/g of the tumor was 12.42±2.15 1 hr p.i. The radio-peptide was quickly cleared from the blood, yielding tumor-to-blood ratios of 39.22±17.36 at 1 hr p.i. and 330.67±131.23 at 24hr p.i. In addition, (177)Lu-DOTA-gluBBN was clearly visualized in PC-3 tumors 1 hr p.i. and significantly inhibited the tumor growth (P<0.05). Treatment-related toxicity in the pancreas and kidneys was not observed, except for slight glomerulopathy. CONCLUSIONS The pharmacokinetic, imaging, and therapy studies suggest that this (177)Lu-DOTA-gluBBN has promising characteristics for application in nuclear medicine, namely, for the diagnosis and treatment of GRPR-overexpressing prostate tumors.
