Hypophosphatemia Is More Common and Is Prognostic of Poorer Outcomes in Severe Alcoholic Pancreatitis.

OBJECTIVES: The aim of this study was to determine if hypophosphatemia is more common in patients with severe alcohol-induced acute pancreatitis (AAP). METHODS: This is a retrospective, single institution, cohort study that analyzed 147 patients admitted to the hospital for AAP. Multivariate logistic regression was used to determine if hypophosphatemia would be related to clinical outcomes of disease severity. RESULTS: Hypophosphatemia was more common in patients with severe AAP at admission; in addition, all patients with severe AAP (100%) eventually developed hypophosphatemia during admission, relative to those with mild (43%) and moderately severe (54%) AAP. The magnitude of the lowest phosphate measurement obtained during admission was lower in patients with severe AAP (mean, 1.5 mg/dL, standard deviation [SD], 0.5 mg/dL) relative to those with mild (mean, 2.6 mg/dL; SD, 0.9 mg/dL) and moderately severe (mean, 2.3 mg/dL; SD, 0.9 mg/dL) AAP (P < 0.001). Finally, patients who developed hypophosphatemia during admission were more likely to require intensive care unit admission (P < 0.001), vasopressors (P = 0.01), or intubation (P = 0.003). CONCLUSIONS: Hypophosphatemia is more common and of greater magnitude in patients admitted to the hospital with severe AAP. In addition, patients with severe AAP who develop hypophosphatemia during admission are more likely to have poorer clinical outcomes.

Five-year mortality trends associated with chronic pancreatitis in South Korea: A population based cohort study.

BACKGROUND: Chronic pancreatitis (CP) is associated with all-cause and cancer-related mortality; however, the risk of mortality associated with alcoholic and non-alcoholic CP remains controversial. This study investigated whether CP increased the risk of 5-year all-cause and cancer-specific mortality compared to a control population. METHODS: This population-based study used data from a sample cohort of the National Health Insurance Service (NHIS) database in South Korea. CP was defined as disease code K86.0 (alcohol-induced CP) and K86.1 (other CP and non-alcoholic CP) from the tenth edition of the International Classification of Diseases. RESULTS: The prevalence of chronic alcoholic pancreatitis increased from 0.01% in 2002 to 0.07% in 2015, and the prevalence of chronic non-alcoholic pancreatitis increased from 0.08% in 2002 to 0.50% in 2015. In the 2010 NHIS cohort (n = 826,909), CP was associated with an increased risk of 5-year all-cause mortality (hazard ratio [HR] = 1.25, 95% confidence interval [CI]: 1.25 to 1.66, P < 0.001). Additionally, non-alcoholic CP was associated with an increased risk of 5-year all-cause mortality (HR = 1.47, 95% CI: 1.27 to 1.71, P < 0.001); in contrast, alcohol-induced CP was not significantly associated with mortality risk (P = 0.569). Similar tendencies were observed for the 5-year cancer-related mortality risk. CONCLUSIONS: In South Korea, the prevalence of alcoholic and non-alcoholic CP increased during 2002-2015. CP may be an independent risk factor for 5-year all-cause and cancer-related mortality. In this study, this association was more evident in patients with non-alcoholic CP.

Etiology and mortality in severe acute pancreatitis: A multicenter study in Japan.

BACKGROUND/OBJECTIVES: Severe acute pancreatitis (SAP) has a high mortality rate despite ongoing attempts to improve prognosis through a various therapeutic modalities. This study aimed to delineate etiology-based routes that may guide clinical decisions for the treatment of SAP. METHODS: Using data from a recent retrospective multicenter study in Japan, we analyzed the association between clinical outcomes, mainly in-hospital mortality and pancreatic infection, and various etiologies while considering confounding factors. We performed additional multivariate analyses and built decision tree models. RESULTS: The 1097 participating patients were classified into the following groups by etiology: alcohol (n = 436, 39.7%); cholelithiasis (n = 230, 21.0%); idiopathic (n = 227, 20.7%); and others (n = 204, 18.6%). Mortality at hospital discharge was 8.4%, 12.2%, 16.7%, and 16.2% in the alcohol, cholelithiasis, idiopathic, and others groups, respectively. According to multivariable analysis, early enteral nutrition (EN) was significantly associated with reduced in-hospital mortality only in the cholelithiasis group. However, there was a consistent association between age and the need for mechanical ventilation and increased mortality, regardless of etiology. Our decision tree models presented different contributing factors depending on the etiology and patient background. Interaction analysis showed that EN and the use of prophylactic antibiotics may influence these results differently according to etiology. CONCLUSIONS: No study has yet used comprehensive models to investigate etiology-related prognostic factors for SAP; our results can, therefore, be used as a reference for improving clinical decisions.

Revised Marshall Score: A New Approach to Stratifying the Severity of Acute Pancreatitis.

BACKGROUND: Modified Marshall Score is one of the severity scores for acute pancreatitis (AP) and is included in the Revised Atlanta Classification, but given its utilization of a set serum creatinine level (sCr), it may misclassify stable patients with chronic kidney disease (CKD) to a more severe class just due to their elevated sCr. AIMS: Our study aims to evaluate the role of CKD in AP and the possibility of utilizing acute kidney injury (AKI) into developing a new scoring system. METHODS: We retrospectively reviewed the electronic medical records of three hundred consecutive patients who were diagnosed with AP during hospitalization. Multiple demographic variables and clinical course indices were collected. Univariate logistic regression was then applied to predict mortality and ICU admission. Finally, receiver operating curve was utilized to compare original versus New Revised Marshall Score. RESULTS: Two hundred and eight-four (284) patients had a definitive diagnosis of AP. When comparing patients who had AKI on admission to those without AKI, the AKI group showed statistically significant higher mortality rate (5.6% vs. 1.1%, p = 0.04). Finally, we substituted the renal part of Marshall Score with our AKIN and we plotted the New "Revised" Marshall Score, which showed a higher AUROC compared to the original modified version (C-statistics 0.93 vs. 0.89, p < 0.05). CONCLUSION: We found that AKI predicts mortality and outperforms the use of a fixed sCr value alone. The use of our New Revised Marshall Score can accurately classify AP severity, avoiding misclassification of AP severity and providing better patient care.

Plasma level of soluble urokinase plasminogen activator receptor (suPAR) predicts long-term mortality after first acute alcohol-induced pancreatitis.

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.

Polymorphisms at PRSS1-PRSS2 and CLDN2-MORC4 loci associate with alcoholic and non-alcoholic chronic pancreatitis in a European replication study.

OBJECTIVE: Several genetic risk factors have been identified for non-alcoholic chronic pancreatitis (NACP). A genome-wide association study reported an association of chronic pancreatitis (CP) with variants in PRSS1-PRSS2 (rs10273639; near the gene encoding cationic trypsinogen) and CLDN2-MORC4 loci (rs7057398 in RIPPLY1 and rs12688220 in MORC4). We aimed to refine these findings in a large European cohort. DESIGN: We studied 3062 patients with alcohol-related CP (ACP) or NACP and 5107 controls. Also, 1559 German patients with alcohol-associated cirrhosis or alcohol dependence were included for comparison. We performed several meta-analyses to examine genotype-phenotype relationships. RESULTS: Association with ACP was found for rs10273639 (OR, 0.63; 95% CI 0.55 to 0.72). ACP was also associated with variants rs7057398 and rs12688220 in men (OR, 2.26; 95% CI 1.94 to 2.63 and OR, 2.66; 95% CI 2.21 to 3.21, respectively) and in women (OR, 1.57; 95% CI 1.14 to 2.18 and OR 1.71; 95% CI 1.41 to 2.07, respectively). Similar results were obtained when German patients with ACP were compared with those with alcohol-associated cirrhosis or alcohol dependence. In the overall population of patients with NACP, association with rs10273639 was absent (OR, 0.93; 95% CI 0.79 to 1.01), whereas rs7057398 of the X chromosomal single nucleotide polymorphisms was associated with NACP in women only (OR, 1.32; 95% CI 1.15 to 1.51). CONCLUSIONS: The single-nucleotide polymorphisms rs10273639 at the PRSS1-PRSS2 locus and rs7057398 and rs12688220 at the CLDN2-MORC4 locus are associated with CP and strongly associate with ACP, but only rs7057398 with NACP in female patients.

Mortality, cancer, and comorbidities associated with chronic pancreatitis: a Danish nationwide matched-cohort study.

BACKGROUND & AIMS: We aimed to assess the risk of death, cancer, and comorbidities among patients with alcoholic and nonalcoholic chronic pancreatitis (CP). METHODS: We performed a nationwide retrospective cohort study, collecting data from Danish registries from 1995 through 2010. We evaluated the prevalences and incidences of death, cancers, and comorbidities among subjects with CP (cases) compared with age- and sex-matched individuals (controls). In total, 11,972 cases (71,814 person-years) and 119,720 controls (917,436 person-years) were included in the analysis. Hazard ratios (HR) were estimated by Cox proportional hazards regression. RESULTS: Forty-six percent of the cases died during the follow-up period, compared with 13.0% of controls (mean age, 63.7 vs 72.1 y; P < .0001), corresponding to a HR of 5.0 for CP (95% confidence interval [CI], 4.8-5.2). Cancer was a frequent cause of death among cases (10.2%) and controls (3.3%). Cancer (particularly pancreatic cancer) was a frequent cause of death among cases; the HR was 6.9 (95% CI, 7.5-11.8). Alcoholic CP did not produce a higher risk for cancer or death than nonalcoholic CP. Cerebrovascular disease (HR, 1.3; 95% CI, 1.2-1.4), chronic pulmonary disease (HR, 1.9; 95% CI, 1.8-2.1), ulcer disease (HR, 3.6; 95% CI, 3.3-3.9), diabetes (HR, 5.2; 95% CI, 5.0-5.6), and chronic renal disease (HR, 1.7; 95% CI, 1.5-1.9) occurred more frequently among patients with CP, but myocardial infarction did not (HR, 0.9; 95% CI, 0.8-1.0). CONCLUSIONS: Based on a Danish nationwide cohort study, individuals with CP are at higher risk for death from cancer (particularly pancreatic cancer) and have a higher incidence of comorbidities than people without CP.

The incidence of acute pancreatitis: impact of social deprivation, alcohol consumption, seasonal and demographic factors.

BACKGROUND: The incidence of acute pancreatitis has increased sharply in many European countries and the USA in recent years. AIM: To establish trends in incidence and mortality for acute pancreatitis in Wales, UK, and to assess how incidence may be linked to factors including social deprivation, seasonal effects and alcohol consumption. METHODS: Use of record linked inpatient, mortality and primary care data for 10,589 hospitalised cases of acute pancreatitis between 1999 and 2010. RESULTS: The incidence of acute pancreatitis was 30.0 per 100,000 population overall, mortality was 6.4% at 60 days. Incidence increased significantly from 27.6 per 100,000 in 1999 to 36.4 in 2010 (average annual increase = 2.7% per year), there was little trend in mortality (0.2% average annual reduction). The largest increases in incidence were among women aged <35 years (7.9% per year) and men aged 35-44 (5.7%) and 45-54 (5.3%). Incidence was 1.9 times higher among the most deprived quintile of patients compared with the most affluent (3.9 times higher for alcoholic acute pancreatitis and 1.5 for gallstone acute pancreatitis). Acute pancreatitis was increased significantly during the Christmas and New Year weeks by 48% (95% CI = 24-77%) for alcoholic aetiology, but not for gallstone aetiology (9%). Alcoholic admissions were increased with higher consumption of spirits and beer, but not wine. CONCLUSIONS: The study shows an elevated rate of alcoholic acute pancreatitis during the Christmas and New Year period. Acute pancreatitis continues to rise, most rapidly for young women, while alcoholic acute pancreatitis is linked strongly with social deprivation.

Endoscopic botulinum toxin injection for the treatment of diabetic gastropathy in pancreas and islet-cell transplant patients.

OBJECTIVES: Gastroparesis is a well-recognized, long-term complication of diabetes. Prokinetic drugs are often not effective, prompting the development of alternative therapies. We report our experience of using one such alternative, endoscopic botulinum toxin injection, to ameliorate diabetic gastropathy in association with pancreas and islet-cell transplant patients. MATERIALS AND METHODS: Three male diabetic patients aged 42 to 55 years had been treated with botulinum toxin in our center. Two patients were both after-simultaneous pancreas-kidney transplant and 1 was awaiting islet-cell transplant after pancreatectomy. Mechanical gastric outlet obstruction was first excluded by radiological and endoscopic studies. Between 100 and 200 IU of toxin were then injected in the prepyloric region using an endoscopic technique. A subjective scoring scale was used to assess symptoms before and after botulinum therapy. RESULTS: Improvement in subjective symptom severity scoring was seen in all patients, with a posttreatment improvement from 55% to 91%. Such improvement was temporary in 2 patients and long-lasting in 1 patient. CONCLUSIONS: The time for improvement of gastric autonomic function after pancreas or islet-cell transplantation remains unclear. Some patients may continue to be symptomatic, leading to increasing morbidity. However, endoscopic botulinum injections may provide short-term relief while waiting for improvement and spare patients the morbidity associated with more-invasive therapies.

Mannan-binding lectin and mannan-binding lectin-associated serine protease 2 in acute pancreatitis.

OBJECTIVES: Complement activation may play a prominent role in acute pancreatitis (AP). Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) participate in complement activation. The objective of the present study was to evaluate the role of MBL and MASP-2 as markers in AP with regard to etiology, inflammatory activity, severity, and development of multiorgan failure. METHODS: Sixty patients with AP were included. All patients were diagnosed and treated according to a standardized regimen. Blood samples were obtained immediately on admission and again on days 1, 2, and 14. RESULTS: Both MBL (P < 0.001) and MASP-2 (P = 0.002) levels changed significantly over time, but without any significant relation to severity, multiorgan failure, or mortality. We found significantly higher levels of MBL (P = 0.04) in alcohol- than in gallstone-induced AP, but no significant difference in MASP-2 levels. CONCLUSIONS: The MBL and MASP-2 acted as acute-phase reactants, but overall, they were not markers for severity, multiorgan failure, nor for mortality in AP. Our results suggest that MBL and MASP-2 play only a minor role in the inflammatory response in AP.

Progression from acute to chronic pancreatitis: prognostic factors, mortality, and natural course.

OBJECTIVES: Knowledge of the natural course of acute pancreatitis (AP) and risk of progression to chronic pancreatitis (CP) is limited. The aims were to describe: (1) the incidence of progression from AP to CP, (2) prognostic factors for progression, and (3) the natural course and mortality of progressive AP. METHODS: During 1977 to 1982, patients admitted to hospitals in Copenhagen with a diagnosis of AP or CP were included in a prospective cohort and followed up by the Danish registries in 2008. The subcohort analyses comprised 352 AP patients. RESULTS: Progressive AP was found in 85 patients (24.1%) during follow-up; 48.2% developed from alcoholic AP, 47.0% from idiopathic AP, and 4.8% from other causes. The mortality rate for patients with progressive AP was 2.7 times higher than in patients with nonprogressive acute pancreatitis, and 5.3 to 6.5 times higher than in the background population. In Cox regression analyses corrected for age, only smoking was of significance for the progression from AP to CP. CONCLUSIONS: Acute pancreatitis can progress to CP, not only from alcoholic but also from nonalcoholic AP. Smoking was the strongest risk factor associated with progression. The mortality rate for these patients was 5 to 6 times the mortality rate in the population.

Epidemiological study of pancreatic diabetes in Japan in 2005: a nationwide study.

OBJECTIVES: There have been few epidemiological studies on pancreatic diabetes. In this study, we determined the incidence and pathology of pancreatic diabetes in Japan. METHODS: We examined the epidemiology of pancreatic diabetes in Japan in 2005 by using a nationwide stratified random-sampling method. Especially, we focused on newly developed diabetes in association with the occurrence of pancreatic disease (true pancreatic diabetes). RESULTS: A total of 19,500 individuals received treatment for true pancreatic diabetes, accounting for 0.8% of patients with diabetes. Prevalence was estimated to be 15.2 per 100,000 with an annual onset incidence of 1.1 per 100,000. With regard to the complications in true pancreatic diabetes, the incidence of retinopathy was lower than that in types 1 and 2 diabetes. Among true pancreatic diabetes with chronic pancreatitis, alcoholic pancreatitis was found in the largest sector. Furthermore, as many as 53.7% were continuous drinkers, and 66.7% received insulin therapy. The frequency of hypoglycemia was high in regular drinkers treated with insulin. Hypoglycemia was a major cause of death in patients who were on insulin and continuous drinkers. CONCLUSION: We clarified the epidemiology of pancreatic diabetes in Japan. Patients with chronic pancreatitis-associated pancreatic diabetes should receive lifestyle guidance focused on drinking cessation.

Incidence, prevalence, etiology, and prognosis of first-time chronic pancreatitis in young patients: a nationwide cohort study.

BACKGROUND/AIMS: Publications on etiology of chronic pancreatitis (CP) are infrequent. Etiologies today encompass genetic disorders. We wanted to describe etiologies of today and identify patients with genetic disorders like hereditary pancreatitis (HP), mutations in Serine Protease Inhibitor Kazal type1 (SPINK1), and the Cystic Fibrosis Transmembrane Conductance Regulator gene (CFTR) among patients formerly considered to have idiopathic CP. METHODS: Data on patients diagnosed with first-time CP < 30 years of age in Denmark identified in the Danish National Registry of Patients were retrieved. Patients previously considered to have idiopathic pancreatitis were offered genetic counseling and evaluation for HP, SPINK1, and CFTR mutations. RESULTS: In the period 1980-2004, 580 patients < 30 years of age presented with CP, the standardized prevalence ratio of CP increased from 11.7 per 100,000 person years in 1980-1984 to 17.0 per 100,000 in 2000-2004 (p < 0.001). The odds ratio (OR) having gallstone-related CP increased in the latter time period, especially in women, that of alcohol-induced CP decreased over time. OR having idiopathic CP increased in the latter period; 50% of patients with idiopathic pancreatitis accepted genetic reevaluation; 28 patients had a genetic mutation that totally or partly could explain their pancreatitis, nine of these had two, and 11 patients had HP. CONCLUSION: The prevalence of CP, especially in women, increased over time. Genetic causes that partly or totally could explain the CP were found in 54.90% (95% CI (40.45-68.62)) of those with idiopathic CP, as a minimum estimation 1.9% (95% CI (1.00-3.47)) of the total cohort had HP.

Binge drinking aggravates the outcomes of first-attack severe acute pancreatitis.

OBJECTIVES: To study the association of binge drinking and the outcomes of severe acute pancreatitis (SAP). METHODS: This retrospective study included 347 patients with first-attack SAP from January 2001 to February 2004. On the basis of the history of binge drinking or not, the patients were divided into the alcohol (n = 77) and the control groups (n = 270). Clinical data of the 2 groups were compared. RESULTS: Patient age and comorbidity were similar between the 2 groups. There were more men (64, 83.1%) than women (13, 16.9%; P < 0.05) in the alcohol and the control groups (111, 41.1%; P < 0.05). The 2 groups had significant differences in admission serum triglyceride levels (5.0 +/- 5.0 vs 3.0 +/- 3.5, P < 0.05), Balthazar computed tomographic score (6.3 +/- 5.4 vs 4.2 +/- 4.5, P < 0.05), and Acute Physiology and Chronic Heath Evaluation II score (19.1 +/- 5.1 vs 16.2 +/- 6.0, P < 0.05). Total mortality and the incidences of complications were higher in the alcohol group than in the control group (P < 0.05). CONCLUSIONS: Binge drinking might be a contributor to the aggravation of first-attack SAP.
