| 1 | Infected pancreatic necrosis: Not necessarily a late event in acute pancreatitis显示文摘It is widely believed that infection of pancreatic necrosis is a late event in the natural course of acute pancreatitis. This paper discusses the available data on the timing of pancreatic infection. It appears that infected pancreatic necrosis occurs early in almost a quarter of patients. This has practical implications for the type, timing and duration of preventive strategies used in these patients. There are also implications for the classification of severity in patients with acute pancreatitis. Given that the main determinants of severity are both local and systemic complications and that they can occur both early and late in the course of acute pancreatitis, the classification of severity should be based on their presence or absence rather than on when they occur. To do otherwise, and in particular overlook early infected pancreatic necrosis, may lead to a misclassification error and fallacies of clinical studies in patients with acute pancreatitis. | Maxim S Petrov Vincent Chong John A Windsor | 2011 | World Journal of Gastroenterology2011，17，27： | 10 |
| 2 | Relationship between the exocrine and endocrine pancreas after acute pancreatitis显示文摘AIM:To determine the prevalence and time course of pancreatic exocrine insufficiency in individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.METHODS: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 withdiabetes 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<0.05 were deemed statistically significant.RESULTS:Eight clinical studies comprising of 234patients met all eligibility criteria.The pooled prevalence of newly diagnosed prediabetes or diabetes in individuals after acute 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.CONCLUSION:Pancreatic exocrine insufficiency occurs in 40%of individuals with newly diagnosed prediabetes or diabetes mellitus after acute pancreatitis.Further studies are needed to investigate the pathogenesis of diabetes in this setting. | Stephanie L M Das James I C Kennedy Rinki Murphy Anthony R J Phillips John A Windsor Maxim S Petrov | 2014 | World Journal of Gastroenterology2014，20，45： | 9 |
| 3 | Pancreatic enzymes and abdominal adipose tissue distribution in new-onset prediabetes/diabetes after acute pancreatitis显示文摘BACKGROUND New-onset prediabetes/diabetes after acute pancreatitis(NODAP)is the most common sequela of pancreatitis,and it differs from type 2 prediabetes/diabetes mellitus(T2DM).AIM To study the associations between circulating levels of pancreatic amylase,pancreatic lipase,chymotrypsin and fat phenotypes in NODAP,T2DM,and health.METHODS Individuals with NODAP(n=30),T2DM(n=30),and sex-matched healthy individuals(n=30)were included.Five fat phenotypes(intra-pancreatic fat,liver fat,skeletal muscle fat,visceral fat,and subcutaneous fat)were determined using the same magnetic resonance imaging protocol and scanner magnet strength for all participants.One-way analysis of covariance,linear regression analysis,and relative importance analysis were conducted.RESULTS Intra-pancreatic fat deposition(IPFD)was higher in NODAP(9.4%±1.8%)and T2DM(9.8%±1.1%)compared with healthy controls(7.8%±1.9%)after adjusting for covariates(P=0.003).Similar findings were observed in regards to visceral fat volume(P=0.005),but not subcutaneous fat volume,liver fat,or skeletal muscle fat.Both IPFD(β=-2.201,P=0.023)and visceral fat volume(β=-0.004,P=0.028)were significantly associated with circulating levels of pancreatic amylase in NODAP,but not in T2DM or healthy individuals.Of the five fat phenotypes,IPFD explained the highest amount of variance in pancreatic amylase concentration(R2=15.3%out of 41.2%).None of the phenotypes contributed meaningfully to the variance in pancreatic lipase or chymotrypsin.CONCLUSION Both NODAP and T2DM are characterized by increased IPFD and visceral fat volume.However,only NODAP is characterized by significant inverse associations between the two fat phenotypes and pancreatic amylase. | Juyeon Ko Loren Skudder-Hill Jaelim Cho Sakina H Bharmal Maxim S Petrov | 2021 | World Journal of Gastroenterology2021，27，23： | 5 |
| 4 | Post-pancreatitis diabetes mellitus and excess intra-pancreatic fat deposition as harbingers of pancreatic cancer显示文摘Progress in the fight against pancreatic cancer has been hampered by many factors.One of them is the inability to detect the disease early in overwhelming majority of patients.The present paper outlines a novel way in which progress could be accelerated.This includes a focus on two harbingers—post-pancreatitis diabetes mellitus and excess intra-pancreatic fat deposition—that converge at affecting the tumor macroenvironment and microenvironment specifically in the pancreas,not other organs.The two entities have the potential to be incorporated into future screening strategies with a view to early detecting of pancreatic cancer. | Maxim S Petrov | 2021 | World Journal of Gastroenterology2021，27，17： | 2 |
