Abstract
BACKGROUND An abnormal and chronic rise of pancreatic enzymes in the blood is most often due to pancreatic diseases, primarily inflammatory or neoplastic, or to numerous extra-pancreatic pathologies. Benign chronic pancreatic hyperenzymemia was described for the first time - as a separate nosological entity - in 1996 by Lucio Gullo et al. They demonstrated the existence of a benign chronic pancreatic hyperenzymemia in asymptomatic subjects and without clinical implications; however, a follow-up of at least 1-2 years is necessary during which no specific symptomatology or morpho-functional impairment of the pancreas should occur, also evaluated through the aid of instrumental diagnostic investigations such as ultrasonography (US), computed tomography (CT) or magnetic resonance cholangio pancreatography (MRCP). METHODS This study was performed with the analysis of a group of 43 subjects arrived at the observation of the Gastroenterology Team of Policlinico Hospital G. Rodolico in Catania-Italy which presented a chronic pancreatic hyperenzymemia, in order to establish the actual benignity of this condition over time. RESULTS During the follow-up, pancreatic alterations and hyperenzymemia were found in 10 patients, while hyperenzymemia was not associated with pancreatic modification in 33 patients. CONCLUSIONS Because of this enzymatic elevation - often conspicuous and lasting - the patient is often particularly anxious. For the same reason, the patient frequently undergoes very expensive laboratory and instrumental diagnostic methods. Good knowledge of the syndrome makes it possible to manage the event more rationally, also to reduce management costs to a minimum.

Abstract
Background Ectopic visceral fat is a major risk factor for obesity complications including insulin resistance and metabolic syndrome. Ultrasonography is a simple bedside screening tool used for the assessment of ectopic visceral fat including fatty pancreas. This study investigates the association between insulin resistance, metabolic syndrome and fatty pancreas detected by ultrasound in children with obesity. Methods This case-control study included 50 prepubertal obese (body mass index [BMI] ≥95th age- and sex-specific percentiles) and 30 lean children (BMI 5th-85th age- and sex-specific percentiles) as the control group. Clinical and laboratory parameters of metabolic syndrome including anthropometric indices of central obesity, blood pressure, fasting glucose and lipid profile were measured. Homeostasis model assessment-insulin resistance (HOMA-IR) was used to assess insulin resistance. Ultrasonographic assessment for pancreatic fat was done for all children. Results Fifty-eight percent of obese children had fatty pancreas. Obese children with fatty pancreas had a higher rate of metabolic syndrome (p=0.013) and insulin resistance than those with non-fatty pancreas (p=0.012). Regression analysis revealed that fatty pancreas is an independent predictor of metabolic syndrome and insulin resistance. Fatty pancreas increases the risk for metabolic syndrome (odds ratio [OR] 11.40; 95% confidence interval [CI]: 2.69-48.22) and insulin resistance (OR 7.85; 95% CI: 2.20-28.05) in children with obesity. Conclusions Obese children have higher pancreatic fat accumulation than lean children. Obese children with fatty pancreas are more susceptible to insulin resistance and metabolic syndrome.

Abstract
After the first description of fatty pancreas in 1933, the effects of pancreatic steatosis have been poorly investigated, compared with that of the liver. However, the interest of research is increasing. Fat accumulation, associated with obesity and the metabolic syndrome (MetS), has been defined as “fatty infiltration” or “nonalcoholic fatty pancreas disease” (NAFPD). The term “fatty replacement” describes a distinct phenomenon characterized by death of acinar cells and replacement by adipose tissue. Risk factors for developing NAFPD include obesity, increasing age, male sex, hypertension, dyslipidemia, alcohol and hyperferritinemia. Increasing evidence support the role of pancreatic fat in the development of type 2 diabetes mellitus, MetS, atherosclerosis, severe acute pancreatitis and even pancreatic cancer. Evidence exists that fatty pancreas could be used as the initial indicator of “ectopic fat deposition”, which is a key element of nonalcoholic fatty liver disease and/or MetS. Moreover, in patients with fatty pancreas, pancreaticoduodenectomy is associated with an increased risk of intraoperative blood loss and post-operative pancreatic fistula.

Age-related changes in pancreatic elasticity: When should we be concerned about their effect on strain elastography? ULTRASONICS 2016; 69:90-96. [PMID: 27070288 DOI: 10.1016/j.ultras.2016.03.018] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2015] [Revised: 03/07/2016] [Accepted: 03/28/2016] [Indexed: 06/05/2023]
Abstract
BACKGROUND Ultrasound strain elastography is one of the useful methods for evaluating pancreatic lesions. During aging, several pancreatic parenchymal changes occur that may interfere with the interpretation of the ultrasound images. We studied age-related changes in pancreatic elasticity using transabdominal ultrasound strain elastography in subjects without known pancreatic disease. METHODS This study was conducted at Nagoya University Hospital, which is an academic medical center, and included 102 subjects (66 women and 39 men) aged 20-85years (mean 58.6±17.5) who underwent transabdominal ultrasonography for screening and follow-up for non-pancreatic diseases. Strain elastography of the pancreas was performed, and the results were subjected to quantitative strain histogram analysis. The correlations of age with four elastographic parameters (Mean, Standard deviation, Skewness, and Kurtosis) and other findings, including hyperechoic pancreas, hyperechoic liver, and diabetes, were evaluated. RESULTS There was a significant correlation between increasing age and elastographic parameters such as the Mean (P=0.004), Skewness (P=0.007), and Kurtosis (P=0.03), and these differences became significant after the age of 40. The prevalence of hyperechoic pancreas increased with age (P<0.001), and the Means were lower in those with hyperechoic pancreas (P=0.004) and a higher body mass index (BMI, P=0.008). No significant correlations with diabetes, hyperechoic liver, or elastographic parameters were demonstrated. CONCLUSION Strain elastography demonstrated elastographic changes in the pancreas with aging that included a decreasing Mean and increasing Skewness and Kurtosis after the age of 40. The prevalence of pancreatic hyperechogenicity increased, and the pancreatic hyperechogenicity was significantly negatively correlated with the Mean.

Abstract
Emerging evidence shows that elevated cholesterol levels are detrimental to health. However, it is unclear whether there is an association between cholesterol and the pituitary. We investigated the effects of a high-cholesterol diet on pituitary hormones using in vivo animal studies and an epidemiological study. In the animal experiments, rats were fed a high-cholesterol or control diet for 28 weeks. In rats fed the high-cholesterol diet, serum levels of thyroid-stimulating hormone (TSH; also known as thyrotrophin), luteinising hormone (LH) and follicle-stimulating hormone (FSH) produced by the basophilic cells of the anterior pituitary were elevated in a time-dependent manner. Among these hormones, TSH was the first to undergo a significant change, whereas adrenocorticotrophic hormone (ACTH), another hormone produced by basophilic cells, was not changed significantly. As the duration of cholesterol feeding increased, cholesterol deposition increased gradually in the pituitary. Histologically, basophilic cells, and especially thyrotrophs and gonadotrophs, showed an obvious increase in cell area, as well as a potential increase in their proportion of total pituitary cells. Expression of the β-subunit of TSH, FSH and LH, which controls hormone specificity and activity, exhibited a corresponding increase. In the epidemiological study, we found a similar elevation of serum TSH, LH and FSH and a decrease in ACTH in patients with hypercholesterolaemia. Significant positive correlations existed between serum total cholesterol and TSH, FSH or LH, even after adjusting for confounding factors. Taken together, the results of the present study suggest that the high-cholesterol diet affected the levels of hormones derived from anterior pituitary basophilic cells. This phenomenon might contribute to the pituitary functional disturbances described in hypercholesterolaemia.

Abstract
BACKGROUND Recent advances in diabetic research involve the evaluation of agents that can regenerate or reverse pancreatic dysfunction. Although gallic acid (GA) has been reported as an antidiabetic agent, its ability to directly reverse altered biochemical parameters in diabetic pancreas has not been demonstrated. METHODS Male albino rats with diabetes induced by the administration of streptozotocin (STZ) (50 mg/kg, intraperitoneally) were treated with oral administration of GA. Antioxidants (enzymatic and non-enzymatic), purinergic enzymes, δ-aminolevulinic acid dehydratase and lactate dehydrogenase were evaluated in the pancreas of both diabetic and nondiabetic animals. RESULTS The pharmacological effect of GA was accompanied by a restoration of the observed decreased levels of vitamin C and reduced glutathione in the pancreas of STZ-treated rats. GA also caused a marked reduction in the high levels of thiobarbituric acid reactive substances observed in the STZ-induced diabetic group. Furthermore, GA also improves the free radical scavenging property, Fe2+ chelating ability and Fe3+ reducing property of the pancreas of diabetic animals. Finally, the inhibition of pancreatic catalase, glutathione S-transferase, δ-aminolevulinic acid dehydratase and lactate dehydrogenase and increased activity of purinergic enzymes accompanied by hyperglycemia were prevented by GA in the pancreas. CONCLUSIONS The direct influence and consequent restoration of altered biochemical conditions in the pancreatic tissue of diabetic animal models by GA makes it a promising antidiabetic candidate especially in pancreatic cell regeneration.

Abstract
PURPOSE To attempt a quantitative analysis of pancreatic echogenicity on transabdominal ultrasonography (US) and evaluate the correlation between pancreatic echogenicity and metabolic syndrome (MetS). METHODS We retrospectively evaluated transabdominal sonograms from 286 subjects. Mean pancreatic body brightness, mean perihepatic fat brightness, and the pancreato-perihepatic fat index (PPHFI) were measured, and reproducibility was analyzed using intraclass correlation coefficients. Associations between the PPHFI and MetS components were analyzed. The optimal PPHFI cutoff value to predict MetS was calculated. RESULTS Reproducibility was good for mean pancreatic body brightness, mean perihepatic fat brightness, and PPHFI with intraclass correlation coefficients of 0.98, 0.95, and 0.95, respectively. Each MetS component showed a significant association with PPHFI. Waist circumference had the strongest association (r = 0.55, p < 0.0001). PPHFI was significantly higher in the MetS (+) group than the MetS (-) group (p < 0.0001), and PPHFI was an independent factor predicting MetS (p = 0.02; odds ratio, 2.89). The best PPHFI cutoff value to predict MetS was 1.97, with a relatively high negative predictive value of 94.1%. CONCLUSIONS We quantitatively analyzed pancreatic echogenicity using the PPHFI on US and found that an increased PPHFI was significantly correlated with MetS. Because increased PPHFI on US may indicate MetS, radiologists and clinicians need to be aware of its implications.

Abstract
BACKGROUND Many authors advocate lipase as the preferred serological test for the diagnosis of pancreatitis and a cut-off level of three or more times the upper limit of normal (ULN) is often quoted. The literature contains no systematic review that explores alternative causes of a lipase level over three times as high as the ULN. Such a review was therefore the objective of this study. METHODS The EMBASE and MEDLINE databases (1985 to August 2013) were searched for all eligible articles. Predetermined data were extracted and independently analysed by two reviewers. RESULTS In total, data from 58 studies were included in the final analysis. The following causes other than pancreatitis of lipase levels exceeding three times the ULN were found: reduced clearance of lipase caused by renal impairment or macrolipase formation; other hepatobiliary, gastroduodenal, intestinal and neoplastic causes; critical illness, including neurosurgical pathology; alternative pancreatic diagnoses, such as non-pathological pancreatic hyperenzymaemia, and miscellaneous causes such as diabetes, drugs and infections. CONCLUSIONS A series of differential diagnoses for significant serum lipase elevations (i.e. exceeding three times the ULN) has been provided by this study. Clinicians should utilize this knowledge in the interpretation and management of patients who have lipase levels over three times as high as the ULN, remaining vigilant for an alternative diagnosis to pancreatitis. The medical officer should be aware of the possibility of incorrect diagnosis in the asymptomatic patient.

Abstract
Purpose In Korea, there are few reports regarding the infiltration of fat tissue in pancreatic parenchyma in surgically resected organs. It is necessary to ascertain the correlation between the presence of fat tissue in the resection margin of the pancreas and the surgery outcome. Methods Fifty four patients who underwent pancreatic resection from Jan. 2007 to Nov. 2008 were enrolled in this study. Pathologic examination was performed to determine the presence of fat tissue in resected pancreatic parenchyma. Statistical correlation between the presence of fat tissue with clinical parameters and postoperative complication rates was analyzed. Results Among the specimens of all fifty four patients, fat tissue was found in 32 specimens of patients (59.3%). Female gender and patients whose body mass index exceeded 24 kg/m2 were statistically correlated with the presence of the fat tissue in pancreatic parenchyma. There was no statistical relationship between infiltration of fat tissue with postoperative complications. Conclusion This study may serve as the base data for study in radiological imaging in detecting pancreatic tissue. A further larger scaled study is needed to validate the result of this study.

Abstract
There is an ongoing discussion on how to diagnose a hyperechogenic pancreas and what is the clinical significance of diffusely hyperechogenic pancreas. Computerized tomography and magnetic resonance imaging are the more appropriate methods to diagnose pancreatic hyperechogenicity when compared with transcutaneous or endoscopic ultrasound examination. More importantly, pancreatic hyperechogenicity may not be a certain indicator of pancreatic fat infiltration. Even if it is true, we do not know the clinical significances of pancreatic fat accumulation. Some suggested that excess fat in the pancreas is associated with chronic pancreatitis. However, several histological studies on human alcoholic chronic pancreatitis did not prove the presence of fatty pancreas in such cases. Thus, except for aging, it is very rare to have truly steatotic pancreas in the absence of certain human diseases.

Abstract
More research is now focused on pancreatic steatosis. Multiple definitions, clinical associations and synonyms for pancreatic steatosis are described in the literature and can be confusing. The integration and comparison of several studies concerning this topic is therefore challenging. In the past, pancreatic steatosis was considered an innocuous condition, a bystander of many underlying diseases (such as congenital syndromes, hemochromatosis and viral infection). However, evidence that pancreatic steatosis (strongly associated with obesity and the metabolic syndrome) has a role in type 2 diabetes mellitus, pancreatic exocrine dysfunction, acute pancreatitis, pancreatic cancer and the formation of pancreatic fistula after pancreatic surgery is emerging. This Review focuses on the different etiological factors and the clinical consequences of pancreatic steatosis.

Abstract
OBJECTIVE Prospectively to evaluate patients with chronic asymptomatic pancreatic hyperenzymemia in order to identify possible pancreatic and non-pancreatic diseases. MATERIAL AND METHODS Seventy-five asymptomatic subjects with long-standing pancreatic hyperenzymemia (45 M, 30 F; mean age+/-SD 51.5+/-16.0 years, range 19-78 years, mean duration+/-SD of pancreatic hyperenzymemia 14.7+/-7.0 months, range 7-34 months) and normal ultrasonographic evaluation were included in this study. The subjects enrolled were carefully interviewed and prospectively evaluated. All patients underwent blood screening. An additional abdominal ultrasound was also carried out and, if considered necessary, other imaging and endoscopic evaluation procedures were used. RESULTS The follow-up of the patients after enrollment in the study was 3.3+/-1.8 years (mean+/-SD). In 38 patients (50.7%), pancreatic or extrapancreatic disease was diagnosed: 20 patients had chronic pancreatitis, 1 had autoimmune chronic pancreatitis, 1 had a benign cyst of the pancreas, 2 had serous cystadenomas, 5 had an intraductal papillary mucinous tumor of the pancreas, 3 had a ductal pancreatic adenocarcinoma, 4 patients had chronic viral hepatitis, and 2 had Crohn's disease. In 37 subjects (49.3%), no pancreatic or extrapancreatic diseases were found (3 subjects had macroamylasemia, 3 had familial hyperenzymemia, 31 had chronic non-pathological pancreatic hyperenzymemia). CONCLUSIONS Subjects having an increase of either amylase or lipase serum levels should undergo a thorough diagnostic work-up prior to establishing the existence of chronic non-pathological pancreatic hyperenzymemia.

Abstract
OBJECTIVES Persistently high serum pancreatic enzymes in asymptomatic subjects are considered a benign idiopathic condition called "non-pathological chronic pancreatic hyperenzymemia" (CPH). However, recent studies with advanced imaging techniques have brought to light abnormal pancreatic findings in a significant proportion of these subjects. The objective of this study was to evaluate pancreatic ductal morphology by secretin-enhanced magnetic resonance cholangiopancreatography (MRCP-S) in subjects with CPH and compare MRCP imaging before and after secretin injection. METHODS In total, 25 consecutive patients with CPH were investigated by MRCP and MRCP-S and compared with 28 consecutive age-matched controls with recurrent upper abdominal pain and normal pancreatic enzymemia. RESULTS MRCP-S showed abnormal pancreatic morphological findings in 13 of the 25 CPH cases (52%) and 1/28 controls (3.6%) (P<0.001). MRCP findings consistent with a diagnosis of chronic pancreatitis, according to the Cambridge classification, were detected in eight CPH cases (32%) after secretin injection but none of the controls. Secretin stimulation boosted the diagnostic yield of MRCP for the diagnosis of chronic pancreatitis fourfold. Pancreas divisum was identified in two CPH cases and one control. A 15-min persisting dilation of the main pancreatic duct was noted in three cases in each group. Compared with MRCP, MRCP-S showed significantly fewer CPH patients with normal findings (P<0.02). CONCLUSIONS MRCP-S detected ductal findings consistent with chronic pancreatitis in one-third of CPH cases. Pancreas divisum and some dysfunction at the level of Vater's papilla were reported in 8 and 12% of the patients, respectively. MRCP-S is to be recommended, instead of MRCP, in the diagnostic work-up of CPH subjects.

Abstract
AIM: To investigate the clinical implications of lipid deposition in the pancreas (fatty pancreas).
METHODS: The subjects of this study were 293 patients who had undergone abdominal computed tomography (CT) and sonography. Fatty pancreas was diagnosed by sonographic findings and subdivided into mild, moderate, and severe fatty pancreas groups comparing to the retroperitoneal fat echogenicity.
RESULTS: Fatty pancreas was associated with higher levels for visceral fat, waist circumference, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterol, triglyceride, high density lipoprotein, free fatty acid, γ-GTP, insulin, and the homeostasis model assessment of insulin resistance (HOMA-IR) than the control group (P < 0.05). HOMA-IR, visceral fat, triglyceride, and ALT also tended to increase with the degree of fat deposition in the pancreas on sonography. In a multivariate logistic regression analysis, HOMA-IR, visceral fat, and ALT level were independently related to fatty pancreas after adjustment for age, body mass index, and lipid profile. The incidence of metabolic syndrome in the fatty pancreas group was significantly higher than in the control group, and the numbers of metabolic syndrome parameters were significantly higher in the fatty pancreas group (P < 0.05).
CONCLUSION: Sonographic fatty pancrease showed higher insulin resistance, visceral fat area, triglyceride, and ALT levels than normal pancreases. Fatty pancreas also showed a strong correlation with metabolic syndrome.

Abstract
Benign pancreatic hyperenzymemia is a newly identified syndrome characterized by an abnormal increase in serum pancreatic enzymes in the absence of pancreatic disease. The hyperenzymemia can occur sporadically or in a familial form, and all of the pancreatic enzymes show elevations. Although the condition is persistent, the enzyme elevations fluctuate considerably, even temporarily returning to normal levels at times. In this review the main characteristics of this syndrome are described.
