Structured alcohol cessation support program versus current practice in acute alcoholic pancreatitis (PANDA): Study protocol for a multicentre cluster randomised controlled trial.

BACKGROUND/OBJECTIVES: The most important risk factor for recurrent pancreatitis after an episode of acute alcoholic pancreatitis is continuation of alcohol use. Current guidelines do not recommend any specific treatment strategy regarding alcohol cessation. The PANDA trial investigates whether implementation of a structured alcohol cessation support program prevents pancreatitis recurrence after a first episode of acute alcoholic pancreatitis. METHODS: PANDA is a nationwide cluster randomised superiority trial. Participating hospitals are randomised for the investigational management, consisting of a structured alcohol cessation support program, or current practice. Patients with a first episode of acute pancreatitis caused by harmful drinking (AUDIT score >7 and < 16 for men and >6 and < 14 for women) will be included. The primary endpoint is recurrence of acute pancreatitis. Secondary endpoints include cessation or reduction of alcohol use, other alcohol-related diseases, mortality, quality of life, quality-adjusted life years (QALYs) and costs. The follow-up period comprises one year after inclusion. DISCUSSION: This is the first multicentre trial with a cluster randomised trial design to investigate whether a structured alcohol cessation support program reduces recurrent acute pancreatitis in patients after a first episode of acute alcoholic pancreatitis, as compared with current practice. TRIAL REGISTRATION: Netherlands Trial Registry (NL8852). Prospectively registered.

Inpatient Alcohol Cessation Counseling Is Associated With a Lower 30-Day Hospital Readmission in Acute Alcoholic Pancreatitis.

BACKGROUND: Alcohol use is a common cause of recurrent acute pancreatitis. Thus, guidelines recommend providing alcohol prevention resources during hospitalization. There is limited data on the real-world implementation of this recommendation. We aimed to assess how often inpatients admitted with alcohol-induced acute pancreatitis (AAP) receive counseling and to determine the impact of counseling on readmissions for AAP. METHODS: We retrospectively studied patients admitted with AAP at a tertiary care center from 2008 to 2018. We compared demographics, clinical features, and outcomes in patients who did and did not receive counseling. Outcomes studied were the proportion of patients with AAP receiving counseling, and readmission rates for AAP at 30 days and 1 year. RESULTS: A total of 243 patients with AAP were identified, of which 115 had inpatient alcohol counseling (47%). Demographic data were comparable between the 2 groups. Fewer patients receiving alcohol counseling were readmitted at 30 days compared with patients not receiving counseling (19.3% vs. 31.2%, P =0.048). At 1 year, the 2 groups had similar readmission rates. On multivariate analysis, patients who received counseling were half as likely to be readmitted in 30 days compared with those who did not receive counseling [odds ratio=0.52 (0.27, 0.98), P =0.046]. CONCLUSIONS: We note that <50% of patients receive alcohol counseling. Patients receiving alcohol counseling were less likely to be readmitted at 30 days, inferring possible value in the intervention provided. Similar readmission rates at 1 year suggest that the single intervention may not have a durable effect on alcohol prevention.

Acute pancreatitis.

Acute pancreatitis is an unpredictable and potentially lethal disease. The prognosis mainly depends on the development of organ failure and secondary infection of pancreatic or peripancreatic necrosis. In the past 10 years, treatment of acute pancreatitis has moved towards a multidisciplinary, tailored, and minimally invasive approach. Despite improvements in treatment and critical care, severe acute pancreatitis is still associated with high mortality rates. In this Seminar, we outline the latest evidence on diagnostic and therapeutic strategies for acute pancreatitis.

Thirty-Day Readmission Among Patients with Alcoholic Acute Pancreatitis.

BACKGROUND/OBJECTIVES: Alcoholic acute pancreatitis (AAP) comprises the second most common cause of acute pancreatitis in the USA, and there is lack of data regarding 30-day specific readmission causes and predictors. We aim to identify 30-day readmission rate, causes, and predictors of readmission. METHODS: Retrospective analysis of the 2016 National Readmission Database of adult patients readmitted within 30 days after an index admission for AAP. RESULTS: Totally, 76,609 AAP patients were discharged from the hospital in 2016. The 30-day readmission rate was 12%. The main cause of readmission was another episode of AAP. Readmission was not associated with higher mortality (1.3% vs. 1.2%; P = 0.21) or prolonged length of stay (5.2 vs. 5.0 days; P = 0.06). The total health care economic burden was $354 million in charges and $90 million in costs. Independent predictors of readmission were having Medicaid insurance, a Charlson comorbidity index score ≥ 3, use of total parenteral nutrition, opioid abuse disorder, prior pancreatic cyst, chronic alcoholic pancreatitis, and other chronic pancreatitis. Obesity was associated with lower odds of readmission. CONCLUSION: Readmission rate for AAP is high and its primary cause are recurrent episodes of AAP. Alcohol and substance abuse pose a high burden on our health care system. Public health strategies should be targeted to provide alcohol abuse disorder rehabilitation and cessation resources to alleviate the burden on readmission, the health care system and to improve patient outcomes.

Alcohol Reduction to Reduce Relapse in Acute Alcoholic Pancreatitis-Missed Opportunities.

AIM: Resuming drinking is a main contributant to recurrence in alcoholic pancreatitis. We assessed current clinical practice in the Netherlands regarding alcohol in managing patients with a first episode of acute alcoholic pancreatitis. METHODS: A survey was distributed to 35 hospitals affiliated with the Dutch Pancreatitis Study Group. We evaluated current support based on various components of brief interventions, the participation of psychosocial healthcare providers, the cooperation with the primary care physicians and the presence of a protocol and its implementation. RESULTS: The response rate was 100% (n = 35). Psychoeducation is the most frequently performed intervention in current support treatment (97% of hospitals). In 17% of hospitals, healthcare providers with a psychosocial background routinely participate in current support treatment; 37% of hospitals create an individual treatment plan in which goals regarding alcohol cessation are specified and only 46% of hospitals provide the primary care physician with specific discharge information; 31% of hospitals indicate that the treatment is uniformly performed within their division of Gastroenterology. Protocols are available in 3% of the hospitals surveyed. Opportunities to involve the patient's social network were not given sufficient priority. CONCLUSION: Among Dutch hospitals, there is no routine management strategy with regard to enhancing treatment for heavy alcohol use in alcoholic pancreatitis patients. There is a need to test a validated support program in randomized studies. Meanwhile, possible opportunities for effecting change are often missed.

Percutaneous Endoscopic Step-Up Therapy Is an Effective Minimally Invasive Approach for Infected Necrotizing Pancreatitis.

BACKGROUND: Infected pancreatic necrosis (IPN) is a major complication of acute pancreatitis (AP), which may require necrosectomy. Minimally invasive surgical step-up therapy is preferred for IPN. AIM: To assess the effectiveness of percutaneous endoscopic step-up therapy in patients with IPN and identify predictors of its success. METHODS: Consecutive patients with AP hospitalized to our tertiary care academic center were studied prospectively. Patients with IPN formed the study group. The treatment protocol for IPN was percutaneous endoscopic step-up approach starting with antibiotics and percutaneous catheter drainage, and if required necrosectomy. Percutaneous endoscopic necrosectomy (PEN) was performed using a flexible endoscope through the percutaneous tract under conscious sedation. Control of sepsis with resolution of collection(s) was the primary outcome measure. RESULTS: A total of 415 patients with AP were included. Of them, 272 patients had necrotizing pancreatitis and 177 (65%) developed IPN. Of these 177 patients, 27 were treated conservatively with antibiotics alone, 56 underwent percutaneous drainage alone, 53 required underwent PEN as a step-up therapy, 1 per-oral endoscopic necrosectomy, and 52 required surgery. Of the 53 patients in the PEN group, 42 (79.2%) were treated successfully-34 after PEN alone and 8 after additional surgery. Eleven of 53 patients died due to organ failure-7 after PEN and 4 after surgery. Independent predictors of mortality were > 50% necrosis and early organ failure. CONCLUSION: Percutaneous endoscopic step-up therapy is an effective strategy for IPN. Organ failure and extensive pancreatic necrosis predicted a suboptimal outcome in patients with infected necrotizing pancreatitis.

Acute management of pancreatitis: the key to best outcomes.

Acute pancreatitis (AP) accounts for over 230 000 US and 28 000 UK hospital admissions annually. Abdominal pain is the most common presenting symptom in AP but may not reflect severity. The clinical challenge is identifying the 20% of patients in whom AP will be severe. We summarise the common aetiologies, the risk stratification strategies including the simplified Bedside Index for Severity in Acute Pancreatitis, acute management approaches in the initial presentation setting, conditions for using advance imaging and opinions on antibiotic use. Some warning signs of impending complications are also discussed.

The Intensity of Brief Interventions in Patients with Acute Alcoholic Pancreatitis Should be Increased, Especially in Young Patients with Heavy Alcohol Consumption.

AIMS: After the first acute alcoholic pancreatitis (AAP), active repeated brief interventions (BIs) have been shown to protect against recurrent acute pancreatitis (RAP). However, in daily hospital practice the treatment of alcohol problems varies. Our aim was to study BIs performed in the clinic during AAP and whether this prevents from future RAP episodes. METHODS: Data on all patients discharged between 10/2010 and 10/2012 with acute pancreatitis as the primary diagnosis were obtained from the hospital database. Patients with the first attack of AAP were included in the study. Documented BIs during hospitalization for AAP and RAP and the development of RAP and chronic pancreatitis during median (range) follow-up of 4.2 (0.2-6.1) years were analyzed. Patients were also contacted with a mailed questionnaire. RESULTS: A total of 74 patients with first AAP during the study period were included. Of these, 32% developed RAP during follow-up. Of the patients, 72% received a documented BI during initial hospitalization, with no difference between patients who later did or did not develop RAP (71 vs. 72%; ns). Younger age (OR = 0.96, 95% CI = 0.92-1.00) and higher AUDIT points (P = 0.044; OR = 5.6; 95% CI = 1.02-30.9 for ≥20 AUDIT points) were associated with RAP. AUDIT test had 70% sensitivity and 71% specificity at a cut-off value of 20 points for predicting RAP. CONCLUSIONS: Only 72% of the patients received a documented BI during the initial hospitalization for AAP. The in-hospital BI as such did not prevent the development of RAP. Young patients with AUDIT points ≥20 are especially at high risk for developing RAP and should be included in a more intense follow-up care program to maximize prevention. SHORT SUMMARY: During hospitalization for acute alcoholic pancreatitis (AAP), one third of the patients did not receive brief interventions (BIs). The in-hospital BI by itself was not sufficient enough to prevent disease recurrence in follow-up of 4 years. Young age and higher AUDIT-points were significant risk factors for recurrent attacks of AAP.

Acute Pancreatitis: Etiology, Pathology, Diagnosis, and Treatment.

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

Acute pancreatitis.

Acute pancreatitis, an inflammatory disorder of the pancreas, is the leading cause of admission to hospital for gastrointestinal disorders in the USA and many other countries. Gallstones and alcohol misuse are long-established risk factors, but several new causes have emerged that, together with new aspects of pathophysiology, improve understanding of the disorder. As incidence (and admission rates) of acute pancreatitis increase, so does the demand for effective management. We review how to manage patients with acute pancreatitis, paying attention to diagnosis, differential diagnosis, complications, prognostic factors, treatment, and prevention of second attacks, and the possible transition from acute to chronic pancreatitis.

The Impact of Social Work Intervention in Alcohol-Induced Pancreatitis in Ireland: a Single-Center Experience.

AIM: To evaluate the effect on recurrent admission for alcohol-induced pancreatitis (that can be up to 48%) of a brief social work intervention for alcohol dependence in a single center in Ireland METHODS: Retrospective cohort study of patients admitted with acute alcohol-induced pancreatitis to a tertiary hospital in Ireland from January 2009 to December 2012. RESULTS: The relapse rate in the cohort of 160 patients with alcohol-induced pancreatitis was 28.1%. There was no difference in the relapse rate of those patients who received a social work intervention compared with those who did not (ANOVA, P = 0.229). The employment status was a significant risk factor for relapse (ANOVA, P = 0.027), but did not differ between those who did, and did not, receive the intervention. CONCLUSION: Although the cohort size did not allow great statistical power, it appears that our hospital's current social work intervention for alcohol-induced pancreatitis is ineffective in preventing relapse. Long-term prospective studies are required to formulate and better implement more efficacious interventions for such patients.

Alcoholic severe acute pancreatitis with positive culture of pancreatic juice treated by nasopancreatic drainage.

BACKGROUND: Severe acute pancreatitis (SAP) is a serious disease associated with alcoholism and has a high mortality rate. Effective treatments have not been established. METHODS: A 58-year-old man was admitted due to alcoholic SAP. Endoscopic retrograde cholangiopancreatography revealed pancreatic calculi at the pancreas head and a stricture in the pancreatic duct from the pancreas head to the body. Endoscopically, nasopancreatic drainage (NPD) was placed through the minor papilla to the pancreas tail beyond the stricture. RESULTS: Pancreatic juice culture was positive for Streptococcus and Enterobacter. The day after NPD, upper abdominal pain was relieved. After changing NPD to a pancreatic stent, the patient was discharged on day 21 post-NPD. CONCLUSION: Alcoholic SAP may reflect aggravation of chronic pancreatitis. The possibility of acute bacterial inflammation should be considered in all cases of chronic alcoholic pancreatitis who present with severe features of inflammation, even in the early stages of an attack. Treatment of this subset of cases by drainage could be of great importance and NPD may be the preferred method.

Activity of neutrophil elastase reflects the progression of acute pancreatitis.

OBJECTIVE: Neutrophil elastase (NE) concentration is associated with progression of acute pancreatitis (AP), but measuring total NE concentration includes biologically inactive NE. This study aims to investigate the relationship between NE activity and the aetiology and severity of AP and associated organ failure. METHODS: Seventy-five patients admitted to our surgery department with a first episode of AP during 2004-2005 were age- and sex-matched to 20 healthy volunteers (controls). NE activity was assessed using venous blood samples obtained on patient admission and after 1, 2 and 14 days. One sample was also taken from each control. ANOVA was used for statistical comparison between groups. RESULTS: Baseline NE activity (geometric mean; 95% confidence intervals) differed between patients (58.6 nM of substrate 7-amino-4-methylcoumarin [AMC]/hour; 48.52-70.72) and controls (31.5 nM AMC/hour; 25.5-39.0) (p = 0.0003), and did not correlate with time between symptom onset and admission. Patients with alcohol-induced AP demonstrated higher mean activity (59.1 nM AMC/h; 44.7-78.2) than those with gallstone-induced AP (41.7 nM AMC/h; 33.9-51.4) (p = 0.0496). NE activity was higher overall in patients with predicted severe AP (60.9 nM AMC/h; 48.0-77.2) than in those with predicted mild AP (42.1 nM AMC/h; 34.9-50.8) (p = 0.027). Patients with respiratory failure had higher NE activity (82.5 nM AMC/h; 57.5-118.4) than those without (43.9 nM AMC/h; 37.6-51.3) (p = 0.0024). CONCLUSIONS: NE activity was associated with predicted severity of AP and AP-associated respiratory failure. Specific NE inhibitors may have therapeutic potential in acute pancreatitis.

Asian chronic pancreatitis: the common and the unique.

Chronic pancreatitis (CP) is a disabling condition worldwide that presents as pain, maldigestion, and diabetes. It is usually perceived as alcohol related, or classified as idiopathic otherwise. However, this is true only for Western countries. Asian CP comprises not only alcohol-related CP but also tropical pancreatitis (TP). Tropical pancreatitis is a unique entity commonly found in South Asia. It shares similar presentations with other CPs for pain and maldigestion. However, its diabetes is more ketosis resistant. Non-surgical approach like endoscopic therapy plus extracoporeal shock wave lithotripsy provides better outcome for TP than other CPs, because of its less strictured pancreatic duct that is more amenable to endoscopic stone clearance. Diagnosis of CP in Asia mainly relies on image studies such as ultrasonography ± computed tomography (CT) scan, and non-invasive tests on fecal chymotrypsin, serum trypsin, and serum pancreatic isoamylase. Endoscopic ultrasonography and intestinal tubing tests are used mainly in some research centers. Autoimmune pancreatitis (AIP) is another CP originated from Asia in large series and subsequently being recognized in the West. AIP patients seldom present with maldigestion until the disease progresses to a very late stage and this occurs in less than one third of patients. In contrast, AIP is usually presented as pseudotumor of the pancreatic head, causing obstructive jaundice. Immunoglobulin G4 level is typically elevated in AIP and can be used as a marker for responsiveness. Without a need of surgery, steroids are the standard treatment. Those who relapse and are resistant to steroids should be placed on long-term immunosuppressive agents.

Management of pancreatic ascites complicating alcoholic chronic pancreatitis.

INTRODUCTION: Pancreatic ascites (PA) is an unusual and little studied complication of chronic alcoholic pancreatitis. Management is complex and is based mainly on empirical data. The aim of this retrospective work was to analyse the management of PA at our centre. PATIENTS AND METHODS: A total of 24 patients with PA complicating chronic alcoholic pancreatitis were managed at the Lille University Hospital between 2004 and 2018. Treatment was initially medical and then, in case of failure, interventional (endoscopic, radiological and/or surgical). Data regarding epidemiology, therapeutic and follow-up data were collected retrospectively. RESULTS: Twenty-four patients were analysed; median follow-up was 18.5 months [6.75-34.25]. Exclusively medical treatment was effective in three of four patients, but, based on intention to treat, medical therapy alone was effective in only two out of 24 patients. Of 17 patients treated endoscopically, treatment was successful in 15 of them. Of the 15 who underwent surgery, external surgical drainage was effective in 13. Multimodal treatment, initiated after 6.5 days [4-13.5] of medical treatment, was effective in 12 out of 14 patients. In total, 21 patients were successfully treated (87%) with a morbidity rate of 79% and a mortality rate of 12.5% (n=3). CONCLUSION: PA gives rise to significant morbidity and mortality. Conservative medical treatment has only a limited role. If medical treatment fails, endoscopic and then surgical treatment allow a favourable outcome in more than 80% of patients.

The recurrence of acute alcohol-associated pancreatitis can be reduced: a randomized controlled trial.

BACKGROUND & AIMS: In the long term, half of patients with their first alcohol-associated acute pancreatitis (AP) develop acute recurrence, alcohol consumption being the main risk factor. None of the recent national or international guidelines for treatment include recommendations aimed to decrease recurrences, possibly because of a lack of studies. This study investigated whether AP recurrences can be reduced. METHODS: One hundred and twenty patients admitted to a university hospital for their first alcohol-associated AP were randomized either to repeated intervention (n = 59) or initial intervention only (n = 61). The patients in the 2 groups did not differ. A registered nurse performed an intervention in both groups before discharge, after which it was repeated in the study group at 6-month intervals at the gastrointestinal outpatient clinic. Acute recurrences during the next 2 years were monitored. RESULTS: There were 9 recurrent AP episodes in 5 patients in the repeated-intervention group compared with 20 episodes (P = .02) in 13 patients (P = .04) in the control group. The recurrence rates were similar during the first 6 months (4 vs 5 episodes), after which the repeated-intervention group had fewer recurrences than the control group (5 vs 15 episodes; P = .02). CONCLUSIONS: The repeated visits at 6-month intervals at the gastrointestinal outpatient clinic, consisting of an intervention against alcohol consumption, appear to be better than the single standardized intervention alone during hospitalization in reducing the development of recurrent AP during a 2-year period.

New insights into alcoholic pancreatitis and pancreatic cancer.

Pancreatitis and pancreatic cancer represent two major diseases of the exocrine pancreas. Pancreatitis exhibits both acute and chronic manifestations. The commonest causes of acute pancreatitis are gallstones and alcohol abuse; the latter is also the predominant cause of chronic pancreatitis. Recent evidence indicates that endotoxinemia, which occurs in alcoholics due to increased gut permeability, may trigger overt necroinflammation of the pancreas in alcoholics and one that may also play a critical role in progression to chronic pancreatitis (acinar atrophy and fibrosis) via activation of pancreatic stellate cells (PSCs). Chronic pancreatitis is a major risk factor for the development of pancreatic cancer, which is the fourth leading cause of cancer-related deaths in humans. Increasing attention has been paid in recent years to the role of the stroma in pancreatic cancer progression. It is now well established that PSCs play a key role in the production of cancer stroma and that they interact closely with cancer cells to create a tumor facilitatory environment that stimulates local tumor growth and distant metastasis. This review summarizes recent advances in our understanding of the pathogenesis of alcoholic pancreatitis and pancreatic cancer, with particular reference to the central role played by PSCs in both diseases. An improved knowledge of PSC biology has the potential to provide an insight into pathways that may be therapeutically targeted to inhibit PSC activation, thereby inhibiting the development of fibrosis in chronic pancreatitis and interrupting stellate cell-cancer cell interactions so as to retard cancer progression.
