Recurrence rates and risk factors for recurrence after first episode of acute pancreatitis: A systematic review and meta-analysis. Eur J Intern Med 2023; 116:72-81. [PMID: 37330318 DOI: 10.1016/j.ejim.2023.06.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/09/2023] [Accepted: 06/10/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND There are a certain number of acute pancreatitis (AP) patients who may suffer from multiple episodes and develop recurrent acute pancreatitis (RAP), but recurrence rates and associated risk factors for RAP vary significantly in the published literature. METHODS We searched PubMed, Web of Science, Scopus, and Embase databases to identify all publications reporting AP recurrence until October 20th, 2022. Meta-analysis and meta-regression were performed to calculate the pooled estimates using the random-effects model. RESULTS A total of 36 studies met the inclusion criteria and all were used in pooled analyses. The overall rate of recurrence after first-time AP was 21% (95% CI, 18%- 24%), and pooled rates in biliary, alcoholic, idiopathic, and hypertriglyceridemia etiology patients were 12%, 30%, 25%, and 30%, respectively. After managing underlying causes post-discharge, the recurrence rate decreased (14% versus 4% for biliary, 30% versus 6% for alcoholic, and 30% versus 22% for hypertriglyceridemia AP). An increased risk of recurrence was reported in patients with a smoking history (odds ratio [OR] = 1.99), alcoholic etiology (OR = 1.72), male sex (hazard ratio [HR] = 1.63), and local complications (HR = 3.40), while biliary etiology was associated with lower recurrence rates (OR = 0.38). CONCLUSION More than one-fifth of AP patients experienced recurrence after discharge, with the highest recurrence rate in alcoholic and hypertriglyceridemia etiologies, and managing underlying causes post-discharge was related to decreased incidence. In addition, smoking history, alcoholic etiology, male gender, and presence of local complications were independent risks for the recurrence.

Diabetes mellitus as a consequence of acute severe pancreatitis: Unraveling the mystery. World J Diabetes 2023; 14:1212-1225. [PMID: 37664472 PMCID: PMC10473947 DOI: 10.4239/wjd.v14.i8.1212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 05/19/2023] [Accepted: 07/06/2023] [Indexed: 08/11/2023] Open
Abstract
The occurrence of diabetes mellitus (DM) in pancreatitis is being increasingly recognized lately. Diabetes can develop not only with chronic pancreatitis but even after the first episode of acute pancreatitis (AP). The incidence of diabetes after AP varies from 18% to 23% in 3 years and reaches up to 40% over 5 years. The exact pathogenesis of diabetes after AP is poorly understood and various mechanisms proposed include loss of islet cell mass, AP-induced autoimmunity, and alterations in the insulin incretin axis. Risk factors associated with increased risk of diabetes includes male sex, recurrent attacks of pancreatitis, presence of pancreatic exocrine insufficiency and level of pancreatitic necrosis. Diagnosis of post-pancreatitis DM (PPDM) is often excluded. Treatment includes a trial of oral antidiabetic drugs in mild diabetes. Often, insulin is required in uncontrolled diabetes. Given the lack of awareness of this metabolic disorder after AP, this review will evaluate current information on epidemiology, risk factors, diagnosis and management of PPDM and identify the knowledge gaps.

Post-acute pancreatitis diabetes: A complication waiting for more recognition and understanding. World J Gastroenterol 2023; 29:4405-4415. [PMID: 37576704 PMCID: PMC10415972 DOI: 10.3748/wjg.v29.i28.4405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 06/22/2023] [Accepted: 07/11/2023] [Indexed: 07/26/2023] Open
Abstract
Post-acute pancreatitis diabetes (PAPD) is the second most common type of diabetes below type 2 diabetes mellitus. Due to the boom in research on this entity carried out during the last decade, its recognition has increased. However, much of the medical community still does not recognize it as a medium and long-term complication of acute pancreatitis (AP). Recent prospective cohort studies show that its incidence is about 23% globally and 34.5% in patients with severe AP. With the overall increase in the incidence of AP this complication will be certainly seen more frequently. Due to its high morbidity, mortality and difficult control, early detection and treatment are essential. However, its risk factors and pathophysiological mechanisms are not clearly defined. Its diagnosis should be made excluding pre-existing diabetes and applying the criteria of the American Diabetes Association after 90 d of resolution of one or more AP episodes. This review will show the evidence published so far on the incidence and prevalence, risk factors, possible pathophysiological mechanisms, clinical outcomes, clinical characteristics and preventive and corrective management of PAPD. Some important gaps needing to be clarified in forthcoming studies will also be discussed.

Quality of life after severe acute pancreatitis: systematic review. BJS Open 2023; 7:zrad067. [PMID: 37619216 PMCID: PMC10449419 DOI: 10.1093/bjsopen/zrad067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 04/13/2023] [Accepted: 05/14/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Severe acute pancreatitis, the most severe form of acute pancreatitis, can alter pancreatic morphology, physiology, and function resulting in long-term morbidity, even after a single episode. This review assesses long-term outcomes and quality of life of severe acute pancreatitis. METHODS A comprehensive literature review was conducted across MEDLINE, Embase, Scopus, and PubMed electronic databases on 18 January 2021 and updated on 26 April 2022 to ensure no new literature had been omitted. All studies were prospective or retrospective, included adult patients (>18 years) presenting with acute pancreatitis for whom data on long-term outcomes specifically after severe acute pancreatitis were reported. Quantitative and qualitative data extraction and synthesis were carried out and no meta-analysis was performed. Outcome measures included aetiology and mortality of severe acute pancreatitis, length of stay, endocrine and exocrine pancreatic insufficiency, chronic symptoms, and quality of life compared with healthy controls as assessed by validated questionnaires. RESULTS Fourteen retrospective cohort studies were included, for a total of 779 patients, using quality of life questionnaires. The most common aetiology of severe acute pancreatitis was biliary (36 per cent) followed by alcoholic (29 per cent). Mortality rate ranged from 5 to 35 per cent and length of stay ranged from 2 to 367 days. Quality of life was somewhat lower in patients with exocrine insufficiency, but unaffected by endocrine insufficiency or chronic symptoms. Quality of life was more likely to be reduced in the first 4 years but normalize thereafter and was more likely to be negatively affected where alcohol was the aetiology. In four studies, the relationship between disease severity and lower quality of life was investigated, and a significant correlation was found. CONCLUSION The review shows how a single episode of severe acute pancreatitis can have a variable effect on long-term quality of life, which is different to previous studies showing a strong reduction in quality of life. This could indicate that in current times treatment modalities are more effective.

Pre-existing, Concurrent/Early-Onset, and Late-Onset Diabetes in Chronic Pancreatitis: Do Outcomes Differ? Dig Dis Sci 2022; 68:1519-1524. [PMID: 36318379 DOI: 10.1007/s10620-022-07742-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 10/17/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND/AIMS Diabetes secondary to endocrine insufficiency in chronic pancreatitis (CP) may develop at any time during the disease course. We sought to evaluate the differences in clinical characteristics and outcomes in CP patients with pre-existing, early-onset, and late-onset diabetes. METHODS We reviewed CP patients seen at our Pancreas Center during 2016-2021. We divided them into four groups: those without diabetes, with pre-existing diabetes, with early-onset diabetes, and with late-onset diabetes. We then compared clinical characteristics and outcomes. RESULTS We identified 450 patients with CP: 271 without diabetes, 99 with pre-existing diabetes, 51 with early-onset diabetes, and 29 with late-onset diabetes. Early-onset diabetics were younger (54.1 vs 57.3 vs 62.5 vs 61.9 years), had more alcohol-related CP (45.1% vs 31.7% vs 32.3% vs 31%), had higher HbA1C levels (8.02% vs 5.11% vs 7.71% vs 7.66%), were more likely to be on insulin (78.4% vs 0% vs 48.4% vs 65.5%), and used more opioids (64.7% vs 43.9% vs 55.1% vs 44.8%) and gabapentinoids (66.7% vs 43.5% vs 48% vs 60.7%) compared to other groups (p < 0.05). Patients who developed diabetes after CP diagnosis had more exocrine insufficiency (72.4% vs 70.6% vs 65.7% vs 53.1%), anatomical complications, and interventions for pain control (p < 0.05). There was no difference in pancreatic cancer in the four groups. CONCLUSION CP patients who are younger and use alcohol are at higher risk of having early-onset diabetes and have poorer glucose control compared other CP patients. Patients who develop diabetes after CP diagnosis have worse outcomes and use more resources.

Combination of Body Mass Index and Fasting Blood Glucose Improved Predictive Value of New-Onset Prediabetes or Diabetes After Acute Pancreatitis: A Retrospective Cohort Study. Pancreas 2022; 51:388-393. [PMID: 35695791 PMCID: PMC9257058 DOI: 10.1097/mpa.0000000000002025] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 04/07/2022] [Indexed: 12/10/2022]
Abstract
OBJECTIVES We sought to evaluate whether combining body mass index (BMI) and fasting blood glucose (FBG) can refine the predictive value of new-onset prediabetes/diabetes after acute pancreatitis (NODAP). METHODS In this retrospective cohort study, we used Kaplan-Meier analysis to compare differences in the NODAP rate among 492 patients with different BMI or FBG levels, or with the combination of these 2 factors mentioned above. RESULTS In all, 153 of 492 (31.1%) eligible patients finally developed NODAP. According to univariate and multivariate analyses, BMI (hazard ratio, 2.075; 95% confidence interval, 1.408-3.060; P < 0.001) and FBG (hazard ratio, 2.544; 95% confidence interval, 1.748-3.710; P < 0.001) were important predictors of the incidence of NODAP. Subsequently, we divided 492 eligible patients into 3 groups according to the median BMI and FBG values, and found that the NODAP rate in the high-risk group was significantly higher than that in the medium-risk group ( P = 0.018) or the low-risk group ( P < 0.001). CONCLUSIONS Body mass index and FBG are independent predictors of NODAP. The combination of BMI and FBG can refine the prediction of NODAP and identify candidates for clinical prevention.

Abstract
Objective To compare the conventional treatment and continuous veno-venous haemofiltration (CVVH) in severe acute pancreatitis (SAP) for the prevention of pseudocyst and walled-off necrosis. Patients and Methods. Forty-two patients were divided into two treatment groups: conventional treatment group contained 24 patients and CVVH had 18. Conventional treatment group patients were treated symptomatically and according to the causes. CVVH group patients were treated symptomatically, and CVVH was done within 2 hours of admission. Results In both groups, there was a decrease in amylase, lipase, CRP, IL-6, IL-10, TNF-alpha, Ranson score, Balthazar score, and APACHE-II score after 72 hours, but the decrease was significantly greater in CVVH patients. There were no any local pancreatic complications in CVVH patients, but 1 patient had an acute peripancreatic fluid collection, 2 patients had pseudocyst, and 2 patients had walled-off necrosis (WON), and a mortality one was seen in the conventional treatment group. Conclusion The present study shows that early CVVH may be able to prevent the formation of pseudocyst and win in SAP patients.

Non-Alcoholic Fatty Liver Disease (NAFLD) Is an Independent Risk Factor for Developing New-Onset Diabetes After Acute Pancreatitis: A Multicenter Retrospective Cohort Study in Chinese Population. Front Endocrinol (Lausanne) 2022; 13:903731. [PMID: 35692404 PMCID: PMC9174455 DOI: 10.3389/fendo.2022.903731] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 04/20/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Numerous studies validated frequent glucose dysfunction in patients with acute pancreatitis (AP). However, the prevalence of new-onset diabetes in individuals after a first episode of AP varies widely among previous studies. This study aims to determine the incidence of post-acute pancreatitis diabetes mellitus (PPDM-A) in Chinese people and further identify potential risk factors that influence diabetes development in patients with AP. METHODS This was a multi-center retrospective cohort study including 6009 inpatients with a first attack of AP. A total of 1804 patients with AP without known endocrine pancreatic disorders or other pancreatic exocrine diseases were eligible for analysis. Data was collected from medical records by hospital information system and telephone follow-ups after discharge. The multiple logistic regression analysis was established to evaluate the potential influencing factors of PPDM-A. RESULTS The prevalence of newly diagnosed diabetes after a first episode of AP in China was 6.2%. Data showed that patients who developed PPDM-A were more likely to be younger (X2 = 6.329, P = 0.012), experienced longer hospital stays (X2 = 6.949, P = 0.008) and had a higher frequency of overweight or obesity (X2 = 11.559, P = 0.003) compared to those with normal glycemia. The frequency of stress hyperglycemia on admission (X2 = 53.815, P < 0.001), hyperlipidemia (X2 = 33.594, P < 0.001) and non-alcoholic fatty liver disease (NAFLD) (X2 = 36.335, P < 0.001) were significantly higher among individuals with PPDM-A compared with control group. Also, patients with PPDM-A were more likely to be hyperlipidemic AP (X2 = 16.304, P = 0.001) and show a higher degree of severity (X2 = 7.834, P = 0.020) and recurrence rate (X2 = 26.908, P < 0.001) of AP compared to those without diabetes. In addition, multiple logistic regression analysis indicated that stress hyperglycemia, hyperlipidemia, NAFLD and repeated attacks of AP were the independent influence factors for developing PPDM-A. CONCLUSION Our study first demonstrated the prevalence of secondary diabetes in Chinese patients after AP. The disorder of glucose metabolism in individuals with AP should be regularly evaluated in clinical practice. Further studies are needed to verify the relationship between liver and pancreas in keeping glucose homeostasis under AP condition.

Longer-term outcome of acute pancreatitis: 5 years follow-up. JGH Open 2021; 5:1323-1327. [PMID: 34950774 PMCID: PMC8674540 DOI: 10.1002/jgh3.12679] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 11/03/2021] [Accepted: 11/05/2021] [Indexed: 01/06/2023]
Abstract
Background and Aim Following an index episode of acute pancreatitis, sometimes the inflammation subsides completely, but sometimes inflammation persists and progresses to chronic pancreatitis, which may be or may not be preceded by recurrent acute pancreatitis. Some patients may also develop diabetes mellitus. There is only limited information on the longer‐term outcome of patients with acute pancreatitis. The aim of this study was to evaluate the longer‐term consequences of acute pancreatitis in the form of the development of recurrent attacks of acute pancreatitis, chronic pancreatitis, diabetes, or pancreatic carcinoma. Methods The index study included 122 patients who presented with their first episode of acute pancreatitis. This retrospective, cross‐sectional survey was performed 5 years after the index episode. Results Of the 122 patients, 96 were available for follow‐up while 4 were known to have died (one from pancreatic cancer). On reassessment after 5 years, 28 of 96 patients had further episodes of pancreatitis. Fifteen patients were diagnosed as having recurrent acute pancreatitis, 13 patients were diagnosed as having chronic pancreatitis, while 17 developed new‐onset diabetes. Recurrent acute pancreatitis was more common in younger patients, while chronic pancreatitis was associated with alcohol abuse and a more severe index episode. The development of diabetes was more common with advanced age. Conclusions In this study, a good proportion of patients progressed to chronic pancreatitis and diabetes within 5 years after surviving acute pancreatitis.

Abstract
Diabetes following acute pancreatitis (AP) is becoming increasingly recognized. It is unclear what subtype of diabetes mellitus (DM) occurs; however, type 3c diabetes mellitus (T3cDM) is gaining increasing recognition. T3cDM has differing pathophysiology than other subtypes of DM and therefore differing disease course and treatment. Current studies have examined the incidence and prevalence of DM following AP, and meta-analyses have shown around 15% develop DM at 1 year with an increasing proportion developing DM at 5 years. It has been observed that some patients have transient hyperglycemia following AP episode with a subset developing persistent impaired glucose metabolism; however, the exact timeline is not well defined. The data on risk factors for developing DM after AP is limited and mixed; however, it is likely that severity of AP may impact the propensity to develop DM. Screening guidelines have not been established following AP; however, screening 1-year post-event will likely capture a sizable proportion of newly developed DM. The endocrine and exocrine pancreas are closely linked, and studies have found significant overlap in dysfunction of both after AP. Finally, there are some data to suggest that diabetes predisposes patients to structural changes in the pancreas and increased risk of developing AP.

Abstract
PURPOSE Patients with a first attack of acute pancreatitis (AP) can develop recurrent acute pancreatitis (RAP). Hence, this study aimed to investigate the clinical features of the disease and the risk factors for RAP. METHODS We performed a retrospective study of 522 patients from Jan 1 to Dec 31, 2006. All patients with AP were followed for 36 months. The primary end point was the rate of RAP. The secondary end points were the risk factors that were evaluated by Cox regression analysis. The cumulative risk of RAP was assessed using Kaplan-Meier analysis. RESULTS 56 of the 522 patients (10.7%) developed RAP. Among those RAP patients, 37 (7.1%) experienced one relapse, 10 (1.9%) experienced two relapses, and 9 (1.7%) experienced three or more relapses. Univariate analysis indicated that age (p = 0.016), male sex, etiology of AP (p = 0.001), local complications (p = 0.001) and Length of stay (LOS) (p = 0.007) were associated with RAP. Multivariate analysis with the Cox proportional hazards model showed that male sex (HR = 2.486, 95% CI, 0.169-0.960, p = 0.04), HTG-associated etiology (HR = 5.690, 95% CI, 2.138-15.146, p = 0.001), alcohol-associated etiology (HR = 5.867, 95% CI, 1.446-23.803, p = 0.013) and current local complications at index admission (HR = 8.917, 95% CI, 3.650-21.789, p = 0.001) were significant independent risk factors for RAP. CONCLUSIONS A first attack of AP led to RAP in 10.7% of patients within 3 years. Male sex was significantly associated with RAP. The etiologies of alcohol and HTG and local complications were the strongest risk factors for recurrent disease. Patients with these characteristics should be given special attention and followed-up closely.

Abstract
BACKGROUND Necrotizing pancreatitis survivors develop complications beyond infected necrosis that often require invasive intervention. Remarkably few data have cataloged these late complications after acute necrotizing pancreatitis resolution. We sought to identify the types and incidence of complications after necrotizing pancreatitis. DESIGN An observational study was performed evaluating 647 patients with necrotizing pancreatitis captured in a single-institution database between 2005 and 2017 at a tertiary care hospital. Retrospective review and analysis of newly diagnosed conditions attributable to necrotizing pancreatitis was performed. Exclusion criteria included the following: death before disease resolution (n = 57, 9%) and patients lost to follow-up (n = 12, 2%). RESULTS A total of 578 patients were followed for a median of 46 months (range, 8 months to 15 y) after necrotizing pancreatitis. In 489 (85%) patients 1 or more complications developed and included symptomatic disconnected pancreatic duct syndrome (285 of 578, 49%), splanchnic vein thrombosis (257 of 572, 45%), new endocrine insufficiency (195 of 549, 35%), new exocrine insufficiency (108 of 571, 19%), symptomatic chronic pancreatitis (93 of 571, 16%), incisional hernia (89 of 420, 21%), biliary stricture (90 of 576, 16%), chronic pain (44 of 575, 8%), gastrointestinal fistula (44 of 578, 8%), pancreatic duct stricture (30 of 578, 5%), and duodenal stricture (28 of 578, 5%). During the follow-up period, a total of 340 (59%) patients required an invasive intervention after necrotizing pancreatitis resolution. Invasive pancreatobiliary intervention was required in 230 (40%) patients. CONCLUSION Late complications are common in necrotizing pancreatitis survivors. A broad variety of problems manifest themselves after resolution of the acute disease process and often require invasive intervention. Necrotizing pancreatitis patients should be followed lifelong by experienced clinicians.

Abstract
Background and Aims: Patients who have an episode of acute pancreatitis (AP) frequently develop diabetes mellitus (DM) over time. The reported incidence of DM after AP varies depending on the severity, etiology and the extent of pancreatic necrosis during AP. We performed a systematic review to determine the incidence of new-onset DM after AP episode (s), and compared the rate of DM in AP patients based upon different disease characteristics. Methods: A total of 31 relevant studies with 13894 subjects were collected from Medline, Embase, and Web of Science. Stata 15 software was used for data analyses in the meta-analysis. Results: The random-effects pooled incidence was 23.0% for DM (95% CI 16.0-31.0%) and 15.0% (95% CI 9.0-23.0%) for DM treated with insulin. We noted substantial heterogeneity in incidence estimates for DM and DM treated with insulin (I 2 = 95.61 and 71.78%; both p < 0·001). The DM incidence was higher in the populations that had a severe AP (SAP) episode than in those with mild acute pancreatitis (MAP) (39 vs. 14%). Patients that displayed pancreatic necrosis during the AP attack(s) had a higher frequency of DM than those without necrosis (37 vs. 11%). In addition, the pooled incidence of DM was higher after alcoholic compared to biliary AP (28 vs. 12%). The incidence of insulin use after SAP and alcoholic AP was 21 and 18%, respectively, with very low heterogeneities. According to duration of follow-up, the pooled rate of DM and insulin use within 5 years after AP was 20 and 14%, while the rate associated with follow-up duration of more than 5 years was elevated to 37 and 25%, respectively. On meta-regression, year of publication, male proportion, age at DM test, and duration of follow-up were neither positively nor negatively associated with the incidence of DM and DM treated with insulin in patients who had a prior AP attack. Conclusion: Patients with AP developed DM after discharge from hospital with a frequency of about 23%. SAP, alcoholic AP and acute necrotizing pancreatitis (ANP) were associated with increased incidence of DM. Assessments of severity, etiology, and pancreatic necrosis are critical for predicting DM development after AP.

Abstract
BACKGROUND Diabetes mellitus can occur after acute pancreatitis (AP), but there are currently no tools for evaluating the risk of developing diabetes after an attack of AP. The aim of the study was to develop a nomogram for prediction of new-onset diabetes mellitus after the first attack of AP. PATIENTS AND METHODS We enrolled 616 patients with first-attack AP. We collected and statistically analyzed demographic data (age, BMI, and duration of hospitalization) and laboratory data (glucose, low-density lipoprotein cholesterol, triglyceride, and cholesterol). RESULTS Univariate analysis suggested duration of hospitalization (P=0.0003), BMI (P=0.0059), cholesterol (P=0.0005), triglyceride (P=0.0005), hemoglobin (P=0.0229), and glucose (P<0.001) at admission were significantly associated with newly developed diabetes after the first-attack AP. Multivariate analysis showed that age [odds ratio (OR)=1.01; 95% confidence interval (CI): 1.00-1.03; P=0.045], BMI (OR=1.06; 95% CI: 1.01-1.12; P=0.018), glucose (OR=1.07; 95% CI: 1.02-1.12; P=0.008), triglyceride (OR=1.03; 95% CI: 1.00-1.06; P=0.035), and low-density lipoprotein-cholesterol (OR=1.18; 95% CI: 1.00-1.38; P=0.044) at admission were important predictors. CONCLUSION The nomogram is a potentially clinically useful tool for predicting new-onset diabetes, which is currently clinically unprecedented. This finding is not confined to the patients with severe AP but is also for patients who have recovered from mild AP. The nomogram must to be validated externally.

Abstract
OBJECTIVE This study aimed to develop a diagnostic model that predicts acute pancreatitis (AP) risk before imaging. METHODS Emergency department patients with serum lipase elevated to 3 times the upper limit of normal or greater were identified retrospectively (September 1, 2013-August 31, 2015). An AP diagnosis was established by expert review of full hospitalization records. Candidate predictors included demographic and clinical characteristics at presentation. Using a derivation set, a multivariable logistic regression model and corresponding point-based scoring system was developed to predict AP. Discrimination accuracy and calibration were assessed in a separate validation set. RESULTS In 319 eligible patients, 182 (57%) had AP. The final model (area under curve, 0.92) included 8 predictors: number of prior AP episodes; history of cholelithiasis; no abdominal surgery (prior 2 months); time elapsed from symptom onset; pain localized to epigastrium, of progressively worsening severity, and severity level at presentation; and extent of lipase elevation. At a diagnostic risk threshold of 8 points or higher (≥99%), the model identified AP with a sensitivity of 45%, and a specificity and a positive predictive value of 100%. CONCLUSIONS In emergency department patients with lipase elevated to 3 times the upper limit of normal or greater, this model helps identify AP risk before imaging. Prospective validation studies are needed to confirm diagnostic accuracy.

Abstract
Objective The aim of this study was to investigate the effect of high-volume hemofiltration (HVHF) on ameliorating immune dysfunction in patients with severe acute pancreatitis (SAP). Methods Twelve patients diagnosed with SAP admitted to the intensive care unit of general surgery, Jinling Hospital, from January 2004 to December 2006 were included in this study. They were assigned to the standard medical therapy group (SMT group, n=4) or HVHF group (n=8) immediately after enrollment, in a 1:2 ratio. The SMT group were given standard treatment for SAP, while the HVHF group were given standard as well as 72-hour HVHF treatment initiated within 2 hours after enrollment. Patients in the 2 groups were comparable for the baseline clinical parameters. All patients were monitored over a 72-hour observation period for continuous clinical status, blood cell counts including monocytes, CD4+ and CD8+ T cells, and HLA-DR expression on monocytes. Blood samples were collected from those patients at 0, 6, 12, 24, 48, and 72 hour after enrollment for measurement of plasma Th1-type cytokines (interleukin-1 [IL-1], IL-2, interferon-γ [IFN-γ], and tumor necrosis factor-α [TNF-α]) and Th2-type cytokines (IL-4, IL-5, IL-6, IL-10, and IL-13) using ELISA. Results Within 72 hours, all measured cytokines except IL-4 were maintained at high levels, accompanied with a low level of peripheral monocytes, CD4+ and CD8+ T cell counts, and HLA-DR expression. Seventy-two hours later, plasma cytokines IFN-γ, IL-1, IL-2, IL-5, IL-10, and IL-13 (p<0.05), but not TNF-α and IL-6, in patients in the HVHF group were significantly reduced, while there was no change for these parameters in the SMT group. Plasma levels of IFN-γ, TNF-α, IL-1, IL-2, IL-5, and IL-13 in the HVHF group were significantly lower than those in the SMT group. Peripheral CD4+ and CD8+ T cells, monocyte count, and HLA-DR expression were increased significantly (p<0.05) only in the HVHF group, not in the SMT group. HLA-DR expression in the HVHF group was significant higher than that in the SMT group (p<0.05). Conclusions HVHF significantly reduced plasma inflammatory cytokine concentrations including those of IFN-γ, TNF-α, IL-1, IL-2, IL-5, and IL-13, while it increased monocyte HLA-DR expression in patients with SAP. The association of plasma cytokine reduction and cellular immune function recovery and clinical outcome needs further investigation.

Abstract
BACKGROUND The prevalence of metabolic diseases continues to rise worldwide, with a growing recognition of metabolic dysregulation after acute inflammatory diseases such as acute pancreatitis (AP). Adipokines and cytokines play an important role in metabolism and the course of AP, but there is a paucity of research investigating their relationship with pancreatic hormones after AP. This study aimed to explore associations between pancreatic hormones and adipokines as well as cytokines to provide insights into the pathophysiology of altered pancreatic hormone secretion following AP [corrected]. METHODS A total of 83 patients previously diagnosed with AP and no prior diabetes or pre-diabetes were recruited into this cross-sectional follow up study. Fasting venous blood samples were collected to analyse a panel of pancreatic hormones and derivatives (amylin, C-peptide, glucagon, insulin, pancreatic polypeptide, somatostatin), adipokines (adiponectin, leptin, retinol binding protein-4, and resistin), and cytokines (interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and tumour necrosis factor-α (TNF-α)). Linear regression analyses were used, and potential confounders were adjusted for in multivariate analyses. RESULTS Insulin was significantly associated with IL-6 in both unadjusted and adjusted models (p = .029 and p = .040, respectively). Amylin was significantly associated with MCP-1 in the unadjusted model (p = .046), and TNF-α in unadjusted and adjusted models (p = .025 and p = .027, respectively). CONCLUSIONS Insulin and amylin have a strong positive association with pro-inflammatory cytokines in patients following an episode of AP. These associations have possible relevance in the development of diabetes associated with diseases of the exocrine pancreas, providing the opportunity to develop novel treatment paradigms.

Predictors for early readmission in acute pancreatitis (AP) in the United States (US) - A nationwide population based study. Pancreatology 2017; 17:534-542. [PMID: 28583749 DOI: 10.1016/j.pan.2017.05.391] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2017] [Revised: 05/23/2017] [Accepted: 05/25/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND & AIMS Population based data on the burden and patterns of acute pancreatitis (AP) early readmissions (≤30-days) are limited. METHODS 2013 Nationwide Readmission Database (NRD) was queried. AP etiology was determined using associated diagnoses codes. Proportion, reasons for readmission, and associated costs were evaluated. Multivariate logistic regression analysis was performed to identify independent predictors for 30-day readmission. RESULTS After exclusions, we identified 178,541 patients with primary diagnosis of AP (mean age 53 ± 17 years, 51% male). 13.7% were readmitted ≤30 days [7.1% in acute biliary pancreatitis (ABP) patients with index cholecystectomy (CCY), 16.3% in ABP patients without CCY, and 14.3% in non-biliary AP patients (p < 0.0001)]. Reasons for readmission included AP, chronic pancreatitis, Pseudocyst/walled off necrosis, biliary tract disease, smoldering symptoms and others. On multivariate analysis male gender, comorbidity status (≥3), non-biliary etiology, organ failure, Pseudocyst/walled off necrosis complications, and patients discharged to extended care facilities were associated with increased risk of readmission. ABP patients with index CCY had a significantly lower risk of early unplanned readmission (odds ratio 0.45, p < 0.0001) but ABP patients with index ERCP did not (p = 0.96). CONCLUSIONS About 1 in 7 AP patients had a 30-day readmission after index hospitalization and about half of these were related to AP. Our data confirms the higher risk of readmission in alcohol and idiopathic AP and a lower risk in ABP. Risk of early unplanned readmission is significantly lower in ABP patients who underwent CCY and not ERCP during index hospitalization. Cholecystectomy should be performed in all ABP patients as per recommended guidelines.

Glucose Variability Measures as Predictors of Oral Feeding Intolerance in Acute Pancreatitis: A Prospective Pilot Study. Dig Dis Sci 2017; 62:1334-1345. [PMID: 28293757 DOI: 10.1007/s10620-017-4530-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 03/01/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND Oral feeding intolerance (OFI) is a common complication in patients with acute pancreatitis (AP). Variations in blood glucose are associated with impaired gastrointestinal function but, to date, measures of glucose variability have not been investigated to predict OFI in patients with AP. AIM To investigate the usefulness of several glucose variability measures in predicting the occurrence of OFI early in the course of AP. METHODS In this prospective cohort study, six measures of glucose variability were calculated prior to the occurrence of OFI. Multivariate binary logistic regression analyses were conducted, and the diagnostic performance and accuracy of glucose variability measures were assessed. RESULTS Of the 95 prospectively enrolled patients, 21 (22%) developed OFI. After adjusting for confounders, admission blood glucose concentration and mean blood glucose concentration were significantly associated with OFI [odds ratio 1.49 (95% confidence interval 1.01-2.20) and odds ratio 1.67 (95% confidence interval 1.07-2.61), respectively]. Both admission blood glucose and mean blood glucose had an area under the curve of 0.83 and positive likelihood ratios of 6.45 and 10.19, respectively. Blood glucose concentration before refeeding, standard deviation of blood glucose concentration, coefficient of variation, and mean amplitude of glycemic excursions were not significantly associated with OFI. CONCLUSION In-hospital blood glucose concentrations are associated with subsequent development of OFI in patients with AP. In particular, admission blood glucose and mean blood glucose could be useful predictors of OFI in this setting.

Abstract
Hyperglycemia is commonly observed during acute and critical illness. Recent studies have investigated the risk of developing diabetes after acute and critical illness, but the relationship between degree of in-hospital hyperglycemia and new-onset diabetes has not been investigated. This study examines the evidence for the relationship between in-hospital hyperglycemia and prevalence of new-onset diabetes after acute and critical illness. A literature search was performed of the MEDLINE, EMBASE, and Scopus databases for relevant studies published from January 1, 2000, through August 4, 2016. Patients with no history of diabetes before hospital discharge were included in the systematic review. In-hospital glucose concentration was classified as normoglycemia, mild hyperglycemia, or severe hyperglycemia for the meta-analysis. Twenty-three studies were included in the systematic review, and 18 of these (111,078 patients) met the eligibility criteria for the meta-analysis. The prevalence of new-onset diabetes was significantly related to in-hospital glucose concentration and was 4% (95% CI, 2%-7%), 12% (95% CI, 9%-15%), and 28% (95% CI, 18%-39%) for patients with normoglycemia, mild hyperglycemia, and severe hyperglycemia, respectively. The prevalence of new-onset diabetes was not influenced by disease setting, follow-up duration, or study design. In summary, this study found stepwise growth in the prevalence of new-onset diabetes with increasing in-hospital glucose concentration. Patients with severe hyperglycemia are at the highest risk, with 28% developing diabetes after hospital discharge.

Abstract
The prognosis of advanced chronic pancreatitis (CP) is poor with the mortality rate approximately two-fold higher than the general population according to a survey of the prognosis of CP. From this standpoint, the concept of early CP was propagated in Japan in 2009 to encourage the medical treatment for the earlier stages of CP. That is, picking up the patients suspicious for early CP and then providing medical treatment for them are very important not only for patients, but also for health care economics. In this review, we described some potential factors associated with the development of CP (alcohol, smoking, past history of acute pancreatitis, aging, gallstone, and gender) that are extremely important to discover patients with early-stage CP.

Abstract
BACKGROUND Most studies of acute necrotizing pancreatitis (ANP) focus on short-term outcomes. We evaluated long-term survival and outcomes following ANP. METHODS Patients treated for ANP at the University of Pittsburgh Medical Center from 2001 to 2008 were studied. Data on presentation and course during initial hospitalization and follow-up (median 34 months) was extracted. RESULTS Mean age of patients (n = 167) was 53 ± 16 years; 70 % were male, 94 % white, 71 % transfers, 52 % biliary etiology, and 78 % had first-attack of acute pancreatitis. Majority had severe disease with high Acute Physiology and Chronic Health Evaluation II (APACHE-II) score (median 11), length of stay (median 26 days), intensive care unit (ICU) admission (87 %), presence of systemic inflammatory response syndrome (SIRS) (90 %), persistent organ failure (60 %), and infected necrosis (50 %). Intervention was needed in 74 %. Eighteen (10.8 %) patients died during index hospitalization, 9 (5.4 %) during the first year, and 13 (7.8 %) after 1 year. Median survival was significantly shorter when compared with age- and sex-matched US general population (9.1 vs. 26.1 years, p < 0.001). Increasing age (HR 1.05), persistent organ failure (HR 4.5), and >50 % necrosis (HR 3.8) were independent predictors of death at 1 year. In eligible patients, new-onset diabetes, oral pancreatic enzyme replacement therapy, and disability were noted in 45, 25, and 53 %, respectively. CONCLUSION ANP significantly impacts long-term survival. A high proportion of patients develop functional derangement and disability following ANP.

Abstract
BACKGROUND & AIMS 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. METHODS 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. RESULTS 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. CONCLUSIONS Based on a retrospective analysis of patients admitted to Dutch hospitals, a first episode of acute pancreatitis leads to recurrent pancreatitis in 17% of patients, and almost 8% of patients progress to CP within 5 years. Progression was associated independently with alcoholic etiology, smoking, and a history of pancreatic necrosis. Smoking is the predominant risk factor for recurrent disease, whereas the combination of alcohol abuse and smoking produces the highest cumulative risk for chronic pancreatitis.

Abstract
BACKGROUND & AIM Acute pancreatitis (AP) and chronic pancreatitis (CP) traditionally have been thought to be distinct diseases, but there is evidence that AP can progress to CP. Little is known about the mechanisms of pancreatitis progression. We performed a meta-analysis to quantify the frequency of transition of AP to CP and identify risk factors for progression. METHODS We searched PubMed, Scopus, and Embase for studies of patients with AP who developed CP, published from 1966 through November 2014. Pooled prevalence and 95% confidence intervals (CIs) were calculated for these outcomes, and sensitivity, subgroup, and meta-regression analyses were conducted. RESULTS We analyzed 14 studies, which included a total of 8492 patients. The pooled prevalence of recurrent AP was 22% (95% CI, 18%-26%), and the pooled prevalence of CP was 10% (95% CI, 6%-15%). Sensitivity analyses yielded a pooled prevalence of CP of 10% (95% CI, 4%-19%) and 36% (95% CI, 20%-53%) in patients after the first occurrence and recurrent AP, respectively. Subgroup analyses found alcohol use and smoking to be the largest risk factors for the development of CP, with pooled prevalence values of 65% (95% CI, 48%-56%) and 61% (95% CI, 47%-73%), respectively. Meta-regression analysis found that men were more likely than women to transition from AP to CP. CONCLUSIONS Ten percent of patients with a first episode of AP and 36% of patients with recurrent AP develop CP; the risk is higher among smokers, alcoholics, and men. Prospective clinical studies are needed to study pancreatitis progression.

Abstract
BACKGROUND Diabetes mellitus (DM) is common in the general population and it poses a heavy burden to society in the form of long-term disability, healthcare use and costs. The pancreas is a key player in glucose homeostasis, but the occurrence of newly diagnosed DM after acute pancreatitis (AP), the most frequent disease of the pancreas, has never been assessed systematically. The aim of this study was to conduct a systematic literature review to determine the prevalence and time course of DM and related conditions after the first attack of AP as well as the impact of covariates. METHODS Relevant literature cited in three electronic databases (Scopus, EMBASE and MEDLINE) was reviewed independently by two authors. The main outcome measures studied were newly diagnosed prediabetes, DM, or DM treated with insulin. Pooled prevalence and 95% CIs were calculated for all outcomes. RESULTS A total of 24 prospective clinical studies, involving 1102 patients with first episode of AP, met all the eligibility criteria. Prediabetes and/or DM was observed in 37% (95% CI 30% to 45%) individuals after AP. The pooled prevalence of prediabetes, DM and treatment with insulin after AP was 16% (95% CI 9% to 24%), 23% (95% CI 16% to 31%), and 15% (95% CI 9% to 21%), respectively. Newly diagnosed DM developed in 15% of individuals within 12 months after first episode of AP and the risk increased significantly at 5 years (relative risk 2.7 (95% CI 1.9 to 3.8)). A similar trend was observed with regard to treatment with insulin. The severity of AP, its aetiology, individuals' age and gender had minimal effect on the studied outcomes. CONCLUSIONS Patients with AP often develop prediabetes and/or DM after discharge from hospital, and have a greater than twofold increased risk of DM over 5 years. Further studies are warranted to determine the optimal strategy for its detection and whether the risk of developing DM after AP can be reduced.

Abstract
BACKGROUND Severe acute pancreatitis (SAP) still has a high mortality rate. Coupled plasma filtration adsorption (CPFA) and continuous veno-venous hemofiltration (CVVH) are 2 extracorporeal blood purification techniques. We hypothesized that CPFA combined with CVVH could preferentially improve prognosis and suppress clinical manifestations of SAP. METHODS In this observational cohort study, 25 patients with SAP were enrolled, in which 12 received CPFA plus CVVH treatment (group 1), and 13 received CVVH therapy (group 2). All the patients underwent a successive 10-day intervention. Clinical indicators were detected before or after the intervention and the results were compared between the 2 groups. The feasibility and the survival rate were evaluated on day 28. RESULTS Compared with group 2, oxygenation index (PaO(2)/FiO(2)), mean arterial pressure, serum amylase, and blood urine nitrogen showed significant differences (all P<0.01) and serum TNF-α, IL-1β, IL-6 were reduced and IL-10 was elevated with time in group 1 (all P<0.01). Liver functions, electrolyte, and acid-base balance did not show significant difference before and after the 10-day treatment with CPFA plus CVVH compared with CVVH (P>0.05). No therapy-related adverse reactions were noted in both groups. Twenty-eight-day survival rate of group 1 was higher than that in group 2 [91.7% (11/12) vs. 53.8% (7/13), P<0.05]. CONCLUSIONS CPFA combined with CVVH was an effective and safe method for treatment of SAP patients, the mechanism being related to its effect on regulating the level of cytokines and serum amylase.

Abstract
A 14-yr-old girl presented with eruptive xanthomata and hypertriglyceridemia. This rare presentation led to diagnoses of diabetes and familial dysbetalipoproteinemia. Type 1 diabetes is a common childhood illness often presenting in adolescence. However, this patient's past medical history revealed valproate-induced severe acute pancreatitis with necrosis at the age of 5 yr. Diabetes, in this case, developed 9 yr later as a result of inadequate pancreatic tissue to support increasing insulin requirements during growth and adolescence. Diabetes was discovered only after the appearance of cutaneous eruptive xanthomata, which appeared due to the previously undiagnosed genetic dyslipidemia. Although the relationship between xanthomata, hypertriglyceridemia, and diabetes may be well known in adults, in children, xanthomata are very rarely the presenting feature of diabetes of any cause. The patient was treated with insulin which induced rapid resolution of hypertriglyceridemia and gradual disappearance of xanthomata. This case acknowledges the rarity of diabetes presenting with xanthomata in adolescence, highlights the importance of searching for an underlying dyslipidemia in such a case, and presents diabetes as a long-term complication of acute pancreatitis in children.

Abstract
The pancreas is a dual organ with exocrine and endocrine functions. The interrelationship of the endocrine-exocrine parts of the pancreas is a complex one, but recent clinical and experimental studies have expanded our knowledge. Many disorders primarily of the exocrine pancreas, often solely in the clinical realm of gastroenterologists are associated with diabetes mellitus (DM). Although, the DM becoming disorders are often grouped with type 2 diabetes, the pathogenesis, clinical manifestations and management differ. We review here data on the association of exocrine-endocrine pancreas, the many hormones of the pancreas and their possible effects on the exocrine functions followed by data on the epidemiology, pathogenesis, and management of DM in chronic pancreatitis, cystic fibrosis, pancreatic cancer, and clinical states after pancreatic surgery.

Hyperglycemia and diabetes mellitus in children with pancreatitis. J Pediatr 2011; 158:612-616.e1. [PMID: 21093873 DOI: 10.1016/j.jpeds.2010.09.066] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2010] [Revised: 07/29/2010] [Accepted: 09/29/2010] [Indexed: 01/15/2023]
Abstract
OBJECTIVE To assess the risk factors for developing hyperglycemia and diabetes mellitus (DM) in children with pancreatitis. STUDY DESIGN Patients (from infants to age 21 years) hospitalized with acute pancreatitis (AP), acute recurrent pancreatitis (ARP), and chronic pancreatitis were studied retrospectively. Subjects with known DM or cystic fibrosis before presentation with pancreatitis were excluded. RESULTS A total of 176 patients met the study criteria. Of these, 140 had AP, 29 had ARP, and 7 had chronic pancreatitis. Severe pancreatitis was associated with hyperglycemia; 41% of the patients with hyperglycemia required insulin, and 8 patients (4.5%) developed DM requiring insulin by the time of discharge. These 8 patients with postpancreatitis DM were more likely to be overweight. Five of the 8 patients had a seizure disorder, and 4 had another comorbidity, such as mental retardation or cerebral palsy. Seven of the 8 patients who developed DM had a single episode of AP, and one patient had ARP. CONCLUSIONS Our findings indicate that hyperglycemia and DM can occur with pancreatitis. In some cases, postpancreatitis DM was associated with mental retardation, seizure disorder, and use of antiseizure medication. As opposed to adults who develop DM after chronic pancreatitis, children can develop DM due to a single episode of AP.

Abstract
Animal and clinical studies have shown that alcohol and its metabolic products, endotoxin, viral infection, drinking pattern, smoking, obesity, genetic variability, and gene polymorphisms were very important in the pathogenesis of alcoholic acute pancreatitis (AAP). The morbidity of AAP has been increased in the past decade, and male gender is strongly associated with increased risk of AAP. The mortality of AAP is high, while the quality of life of survivors of severe AAP is low. In this paper, we review the pathogenesis and clinical characteristics of AAP.

Pancreatic functional impairment following acute necrotizing pancreatitis: long-term outcome of a non-surgically treated series. Dig Liver Dis 2010; 42:149-52. [PMID: 19836318 DOI: 10.1016/j.dld.2009.08.007] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2009] [Revised: 07/21/2009] [Accepted: 08/24/2009] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Patients who survive an episode of acute necrotizing pancreatitis may develop endocrine and exocrine pancreatic functional impairment; often these patients have undergone pancreatic surgery during the acute episode. Aim of this study is to report the results of a long-term follow-up of patients recovering from an episode of acute necrotizing pancreatitis which had not been treated surgically during the index hospital admission. DESIGN AND SUBJECTS Sixty-five consecutive patients enrolled between January 1990 and December 1993, prospectively followed through December 2006. RESULTS Median follow-up period was 179.5 months (range 156-203). 40 patients (61.5%) who completed follow-up were analysed. Endocrine function: 2 patients (5%) were diabetic before the pancreatitis episode, and 6 (15.7%) developed overt diabetes; diabetes appeared within the 3rd year after acute pancreatitis in 2 patients, between the 3rd and 4th year in 2 patients, and between the 5th and 6th year in the last 2 patients. Exocrine function: 9 patients (22.5%) showed fecal elastase impairment; in all patients ultrasound was normal and fecal elastase returned above the normal limit during follow-up. CONCLUSIONS After an episode of acute necrotizing pancreatitis treated without surgery, the endocrine and exocrine function is not frequently impaired after long-term follow-up. Reduction in exocrine function is transient and complete recovery is achieved in all patients within a few years.

Abstract
This review highlights advances in acute pancreatitis (AP) made in the past year. We focus on clinical aspects of AP - severe disease especially - and risk stratification tools to guide the clinical care of patients. Most patients with AP have mild disease that requires a diagnostic evaluation, self-limited supportive care, and a short hospital stay. In patients with potentially severe AP, it is important for clinicians to use available risk-stratifying tools to identify high-risk patients and initiate timely interventions such as aggressive fluid resuscitation, close monitoring, early initiation of enteral nutrition, and appropriate use of endoscopic retrograde cholangio-pancreatography. This approach decreases morbidity and possibly mortality and is supported by evidence drawn from recent clinical guidelines, historical literature, and the highest quality studies published in the last year.

Abstract
AIM: To explore the therapeutic effect of pancreatic clearance pills (Qingyi pian) on severe acute pancreatitis.
METHODS: From January 1997 to December 2007, 272 cases of severe acute pancreatitis were randomly divided into traditional Chinese medicine group and control group. Their recurrence and nutritional status were recorded.
RESULTS: The 1-year AP recurrence rate after discharge was 46.3% (126/272). The 1-year AP recurrence rate of the Chinese medicine group was significantly lower than that of the control group (39.9% vs 53.0%, P < 0.05). Nutritional damage score at 6 and 12 mo after discharge was significantly lower in Chinese herb group than in the control group (t = 2.23, 2.77, P < 0.05 or 0.01).
CONCLUSION: Use of pancreatic clearance pills within the first 3 months after discharge reduces long-term AP recurrence rate and improves nutritional status for SAP patients.
