Aronen A, Aittoniemi J, Huttunen R, Nikkola A, Nikkola J, Limnell O, Nordback I, Sand J, Laukkarinen J. Plasma level of soluble urokinase plasminogen activator receptor (suPAR) predicts long-term mortality after first acute alcohol-induced pancreatitis. Eur J Intern Med 2019; 64:72-75. [PMID: 31060962 DOI: 10.1016/j.ejim.2019.04.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Revised: 02/03/2019] [Accepted: 04/19/2019] [Indexed: 11/25/2022]
Abstract
BACKGROUND Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker associated with inflammatory and certain malignancies. Earlier we have shown that plasma suPAR (P-suPAR) predicts severity of acute alcohol-induced pancreatitis (AAP) on admission. Our aim was to investigate whether P-suPAR levels predict AAP recurrences or mortality during long-term follow-up after first AAP. METHODS Eighty-three patients (median age 47.5, range 25-71 years) suffering their first AAP during 2001-2005 were recruited and followed prospectively for 9 years with a median follow-up time of 7.0 (range 0.3-9.8) years. P-suPAR was measured by enzyme-linked immunosorbent assay (ELISA) from the samples taken at follow-up visits. Survival was registered in November 2014. RESULTS P-suPAR level on admission or after recovery of the first AAP did not predict the recurrence of AAP. However, higher P-suPAR measured after recovery of first AAP (3.6 vs. 2.9 ng/mL) predicted mortality during follow-up period (hazard ratio 1.48, p = .008). Cut-off value for P-suPAR indicating a higher risk for 10-year mortality resulted a value of ≥3.4 ng/mL. When adjusted for other covariates, P-suPAR above cut-off level retained its statistical significance as an independent factor. CONCLUSIONS P-suPAR level on admission or after recovery of the first AAP does not predict the recurrence of AAP during long-term follow-up. However, P-suPAR ≥3.4 mg/mL measured after recovery from first AAP is associated with an increased risk of 10-year mortality as an independent factor. This can be used to detect patients with highest risk after AAP, in order to focus the preventive healthcare actions.

Abstract
INTRODUCTION Acute Pancreatitis (AP) is an emerging health problem world-wide and it is a major cause of admissions for gastrointestinal disease in many countries. Amongst the more common causes (alcohol and gallstones), recent evidence has emerged indicating that smoking is an independent risk factor for AP. However, the mechanisms involved in smoking-induced AP have not been completely elucidated. This review puts together all the published evidence in literature to present the clinical and laboratory evidence relating smoking to the causation of AP. DISCUSSION The two main metabolites from cigarette smoke, namely nicotine and NNK are able to induce functional and histological changes within the pancreas consistent with AP. The major mechanisms involved include their action on acinar cells and zymogen secretion through pathways involving CCK and the nicotinic preganglionic receptors. Effects on the pancreatic microvasculature may be mediated through the nitric oxide pathway. There is indirect evidence to suggest that nicotine and acrolein may lead to CFTR dysfunction thereby influencing ductal secretion. However, direct evidence for this effect is needed. The effect of cigarette smoke metabolites on stellate cells and the islets warrants further investigation in the context of pathogenesis of AP. CONCLUSION Using a step-wise approach, the review revisits the effects of the various metabolites of cigarette smoke on the constituents of the pancreas (exocrine, endocrine, neurohormonal, stellate cells, ductal system) and highlights their proven, and potential, mechanisms in triggering off an attack of AP.

Abstract
There is paucity of literature on the relation of obesity with recurrent and chronic pancreatitis. We recorded the clinical details and the outcome of five patients with recurrent pancreatitis who had components of the metabolic syndrome. Their age ranged from 8 to 20 years. All five patients had acanthosis nigricans. Body mass index (BMI) could not be evaluated as these patients lost weight following episodes of pancreatitis. Three patients had two or more first-degree relatives who had diabetes mellitus. Only one patient had severe necrotizing pancreatitis. Coexisting liver disease was seen in two patients. Elevated serum cholesterol levels and moderately elevated serum triglycerides along with elevated serum amylase levels observed in these patients suggest possibility of a different mechanism from that of hypertriglyceridemia-related pancreatitis. Evaluation of pancreatic steatosis should be considered in patients with pancreatitis in the setting of metabolic syndrome.

Abstract
This paper gives practical guidelines for diagnosis and treatment of chronic pancreatitis. Statements have been elaborated by working teams of experts, by searching for and analysing the literature, and submitted to a consensus process by using a Delphi modified procedure. The statements report recommendations on clinical and nutritional approach, assessment of pancreatic function, treatment of exocrine pancreatic failure and of secondary diabetes, treatment of pain and prevention of painful relapses. Moreover, the role of endoscopy in approaching pancreatic pain, pancreatic stones, duct narrowing and dilation, and complications was considered. Recommendations for most appropriate use of various imaging techniques and of ultrasound endoscopy are reported. Finally, a group of recommendations are addressed to the surgical treatment, with definition of right indications, timing, most appropriate procedures and techniques in different clinical conditions and targets, and clinical and functional outcomes following surgery.

Abstract
OBJECTIVES To assess the evidence for tobacco smoking as a risk factor for the causation of chronic pancreatitis. METHODS We performed a meta-analysis with random-effects models to estimate pooled relative risks (RRs) of chronic pancreatitis for current, former, and ever smokers, in comparison to never smokers. We also performed dose-response, heterogeneity, publication bias, and sensitivity analyses. RESULTS Ten case-control studies and 2 cohort studies that evaluated, overall, 1705 patients with chronic pancreatitis satisfied the inclusion criteria. When contrasted to never smokers, the pooled risk estimates for current smokers was 2.8 (95% confidence interval [CI], 1.8-4.2) overall and 2.5 (95% CI, 1.3-4.6) when data were adjusted for alcohol consumption. A dose-response effect of tobacco use on the risk was ascertained: the RR for subjects smoking less than 1 pack per day was 2.4 (95% CI, 0.9-6.6) and increased to 3.3 (95% CI, 1.4-7.9) in those smoking 1 or more packs per day. The risk diminished significantly after smoking cessation, as the RR estimate for former smokers dropped to a value of 1.4 (95% CI, 1.1-1.9). CONCLUSIONS Tobacco smoking may enhance the risk of developing chronic pancreatitis. Recommendation for smoking cessation, besides alcohol abstinence, should be incorporated in the management of patients with chronic pancreatitis.

Abstract
BACKGROUND/AIMS Obesity is a known risk factor for severe acute pancreatitis (AP). Since alcoholic chronic pancreatitis (ACP) is closely linked to alcoholic AP, overweight before disease onset might impact on incidence and outcome of ACP, and represent an additional risk factor for ACP. This issue has not been investigated, despite discussions on the 'hypercaloric-high-fat' hypothesis as an additional risk factor for ACP for many years. METHODS The study is part of our prospective long-term study of a large, mixed, medical/surgical series of ACP patients. All cooperative patients were studied according to a protocol regarding clinical symptoms, physical status, routine laboratory tests, pancreatic function and pancreatic morphology (e.g. calcification) at yearly follow-ups. Our study includes 227 ACP patients with recorded body mass index (BMI) before disease onset followed up on average for 18 years from chronic pancreatitis (CP) onset. RESULTS Males predominated (89.9%), age at onset averaged at 36 years, and exocrine insufficiency (97.4%) and calcification (88.1%) developed in virtually all patients. Surgery for B-type pain was performed in 57.7%, and death occurred in 62.8%. Overweight before disease onset was found in 54.2% (obesity in 15.0%) compared to 37.7% (3.1%) from a contemporary male control population. The highest BMI before disease onset did not impact on some major variables of ACP such as gender, age, progression of exocrine insufficiency, diabetes and calcification, and mortality from CP, except for a delayed progression rate of ACP indices in the surgical series. CONCLUSION Overweight before disease onset appears to be another risk factor for ACP, supporting the 'hypercaloric-high-fat' hypothesis. and IAP.

Abstract
BACKGROUND AND AIMS It is not completely understood whether smoking contributes to chronic pancreatitis (CP). Past studies have included mostly patients with alcohol-related and severe CP. Our aim was to assess the relationship of smoking and CP adjusting for alcohol and other clinical risk factors. METHODS A cross-sectional study was performed of patients referred to the pancreatic disease clinic in the past 2 years with abdominal pain and suspected CP. Patients were questioned on their smoking and alcohol habits. Patients underwent an etiological workup and diagnostic evaluation for early and late CP comprised of computed tomography scan and combined endoscopic ultrasound and secretin endoscopic pancreatic function test if indicated. Logistic regression was used to determine the association of current smoking with CP adjusting for other risk factors. RESULTS The adjusted odds ratio (OR) for current smoking was 1.99 (95% CI 1.01, 3.91). Other significant predictors included consumption of > or =10 alcohol drinks/week, advancing age, history of acute pancreatitis, and the presence of another etiological factor. Smoking was also independently associated with exocrine insufficiency (OR 2.00, 95% CI 1.07, 3.75) and calcifications (OR 2.68, 95% CI 1.03, 6.94). CONCLUSION Active cigarette smoking is associated with CP adjusting for alcohol and other risk factors. and IAP.

Abstract
Chronic pancreatitis is a multifactorial disease. Mutations in the chymotrypsin C gene may encourage the development of chronic pancreatitis. Smoking is an important factor in the development and progression of chronic pancreatitis. The signs identified in endoscopic ultrasound should be categorized when diagnosing chronic pancreatitis, since not all have the same diagnostic value. The clinical manifestations of autoimmune pancreatitis are more varied than initially described and depend on the population studied. The criteria used for the diagnosis of autoimmune pancreatitis have not been well defined and treatment may require the use of immunomodulators. Antioxidant therapy has beneficial effects in the long term in patients with chronic pancreatitis. Some clinical manifestations found in patients with irritable bowel syndrome may be caused by unidentified pancreatic insufficiency. Capsule endoscopy shows that cystic fibrosis presents signs of small bowel enteropathy.

Abstract
OBJECTIVE In an earlier retrospective study we showed that 46% of patients with acute alcoholic pancreatitis had recurrent attacks within 10-20 years, about 30% having a recurrence during the first 3 years. The aim of this prospective follow-up study was to determine the risk factors associated with recurrences. MATERIAL AND METHODS Sixty-eight patients, (59 M, 9 F, mean age 46 years, range 25-71 years) who survived their first acute alcohol-induced pancreatitis from January 2001 to January 2004 volunteered to participate in the study. The diagnostic criteria for acute pancreatitis were epigastric pain, serum amylase > 3 times the upper normal range, elevated serum C-reactive protein (CRP), and signs of acute pancreatitis in imaging. Other etiologies were excluded. Alcohol consumption and dependency were detected by the Alcohol Use Disorders Identification Test (AUDIT) and the Short Alcohol Dependence Data (SADD), respectively, and by attempting to evaluate recent use in grams of pure alcohol. Social and demographic data of the patients, smoking, body mass index, and the severity of the pancreatitis were recorded. Serum and fecal markers of the endocrine and exocrine function and secretin-stimulated MRCP were studied. The patients were followed for a median 38 (25-61) months for recurrences, and at the 2-year time-point had a follow-up visit to investigate any changes in alcohol consumption. RESULTS Seventeen (25%) patients had recurrences of acute alcoholic pancreatitis during the follow-up. Pre-illness alcohol consumption, the severity of the pancreatitis, patient's social or demographic data, pancreatic function tests or morphologic changes in MRCP, or smoking did not correlate with recurrence. None of the 13 patients with consistent total abstinence from alcohol at 2 years developed recurrent pancreatitis compared with 17 out of 51 (33%) patients with at least some alcohol consumption (p = 0.02). Use of other sedatives than alcohol before the first attack of pancreatitis was an independent risk factor associated with recurrence (HR = 6.95, 95% CI 2.45-19.72, p < 0.001). A lower reduction in dependency on alcohol (less decreased SADD points) during 2 years was associated with a higher recurrence rate (HR = 0.921/each reduced point, 95% CI 0.872-0.974, p=0.004). CONCLUSIONS Contrary to chronic pancreatitis, smoking was not found to be a risk factor for recurrent episodes after the first attack of acute alcoholic pancreatitis. Abstinence from alcohol protects against recurrent pancreatitis. Patients who developed recurrent acute pancreatitis had increased dependency on alcohol, demonstrated by the use of other sedatives in addition to alcohol and supported by the less decreased dependency during the follow-up.

Abstract
Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.

Abstract
Only a small proportion of heavy drinking individuals develop pancreatitis. The environmental and host cofactors shown to have an association with alcoholic pancreatitis are smoking and race. The known genetic variations and polymorphisms do not seem to play an important role in alcoholic pancreatitis. Newer developments in the understanding of complex disorders allow clinicians to understand better the role of cofactors and interactions between known and yet unknown environmental and genetic factors in causing alcoholic pancreatitis.

Abstract
OBJECTIVES The aim of the study was to assess the effect of cigarette smoking on the endocrine pancreatic function by determining the levels of serum glucose and plasma insulin as well as by defining immunohistochemical localization of insulin and glucagon in tissue specimens of the pancreata derived from healthy persons and smoking and nonsmoking patients with diagnosed chronic pancreatitis (CP). METHODS The oxidative method was used to measure fasting glycemia in blood plasma and the method enzyme-linked immunoassay to determine the level of insulin in plasma. Immunohistochemical localization of hormones in paraffin tissue specimens of the pancreas was performed using the LSAB2-HRP visual test with polyclonal insulin and glucagon antibodies. The intensity of immunohistochemical reaction was calculated with digital imaging methodology. RESULTS The study revealed a substantially higher level of serum glucose in smoking CP patients and in healthy persons compared with nonsmoking patients and healthy persons, whereas insulin concentration in smoking patients was statistically lower than in nonsmokers. Smoking patients showed significantly lower expression of insulin and glucagon in the pancreas compared with nonsmoking patients and healthy persons. CONCLUSIONS Impairment of the endocrine function of beta and alpha cells in the pancreatic islets is frequently manifested by complications in pancreatitis resulting among others from long-term smoking.

Abstract
BACKGROUND/AIMS Obesity has been associated with a worse prognosis in acute pancreatitis. According to some authors, obesity favours the development of local complications, while according to other reports obese patients presented more frequently systemic complications. Few studies find a relationship between obesity and mortality in acute pancreatitis. We conducted a meta-analysis of several reports that evaluate the relationship between obesity and the outcome of acute pancreatitis in order to assess its prognostic role in this disease. METHODS A MEDLINE search was conducted from 1965 to December 2002 with search terms including obesity, body mass index (BMI) and pancreatitis. A total of 12 reports were identified. Of these, only four studies included patients with mild and severe acute pancreatitis and measured obesity by BMI. The end points of the meta-analysis were the severity of acute pancreatitis, local complications, systemic complications and mortality. Obesity was defined when BMI was > or =30 kg/m2. Pooled odds ratio (OR) and confidence intervals (CI) were calculated according to the Mantel-Haenszel method, and heterogeneity was assessed by the multiplicative inverse variance method. RESULTS A total of 607 patients were evaluated. There was no heterogeneity for the variables severity, systemic complications, local complications and mortality among the included studies. Severe AP was significantly more frequent in obese patients (OR 2.6, 95% CI 1.5-4.6). Furthermore, those patients developed significantly more systemic (OR 2.0, 95% CI 1.1-4.6) and local complications (OR 4.3, 95% CI 2.4-7.9). Mortality in obese patients was only slightly higher (OR 1.3, 95% CI 0.5-3.6). CONCLUSION Obesity is a prognostic factor favouring the development of systemic and local complications in this disease. Therefore, it should be used routinely as part of the initial assessment of the severity of a case of acute pancreatitis.

Abstract
An increasing number of novel mutations are associated with chronic pancreatitis. Some cause a high-penetrance, autosomal dominant type of clinical picture (eg, mutations at codons 29 and 122 of the cationic trypsinogen gene), whereas others have a low penetrance or are frequent in the general population (eg, mutations in Kazal type 1 [SPINK1] and in codons 16, 22, and 23 of the cationic trypsinogen gene) and act as disease modifiers. The results of recent studies indicate that smoking adversely affects the course and complications of chronic pancreatitis (more frequent and faster rate of calcification and higher risk of development of pancreatic cancer). Thus, regardless of the cause of chronic pancreatis, patients with this condition should not smoke. Using current diagnostic criteria, the accuracy of endoscopic ultrasound for the diagnosis of chronic pancreatitis is not good. For example, 39% of dyspeptic persons without any other evidence of chronic pancreatitis fulfilled the endoscopic ultrasound criteria for chronic pancreatitis. Diabetes frequently occurs in chronic pancreatitis, but it is not prevented or increased by pancreatic surgery. Islet cell autotransplantation holds promise for the prevention of diabetes in patients requiring total pancreatectomy if the pancreas is not extensively fibrotic. Splenic vein occlusion is present in 7% of patients undergoing surgery for chronic pancreatitis, but fewer than one fifth of these patients have variceal bleeding before or after surgery.
