BACKGROUND: Data on the incidence and clinical relevance of gallstones in patients with suspected acute alcoholic pancreatitis are lacking and are essential to minimize the risk of recurrent acute pancreatitis. The aim of this study was to assess the incidence of gallstones and the associated rate of recurrent acute pancreatitis in patients with presumed acute alcoholic pancreatitis. METHODS: Between 2008 and 2019, 23 hospitals prospectively enrolled patients with acute pancreatitis. Those diagnosed with their first episode of presumed acute alcoholic pancreatitis were included in this study. The term gallstones was used to describe the presence of cholelithiasis or biliary sludge found during imaging. The primary outcome was pancreatitis recurrence during 3 years of follow-up. RESULTS: A total of 334 patients were eligible for inclusion, of whom 316 were included in the follow-up analysis. Gallstone evaluation, either during the index admission or during follow-up, was performed for 306 of 334 patients (91.6%). Gallstones were detected in 54 patients (17.6%), with a median time to detection of 6 (interquartile range 0-42) weeks. During follow-up, recurrent acute pancreatitis occurred in 121 of 316 patients (38.3%), with a significantly higher incidence rate for patients with gallstones compared with patients without gallstones (59% versus 34.2% respectively; P < 0.001), while more patients with gallstones had stopped drinking alcohol at the time of their first recurrence (41% versus 24% respectively; P = 0.020). Cholecystectomy was performed for 19 patients with gallstones (36%). The recurrence rate was lower for patients in the cholecystectomy group compared with patients who did receive inadequate treatment or no treatment (5/19 versus 19/34 respectively; P = 0.038). CONCLUSION: Gallstones were found in almost one in every five patients diagnosed with acute alcoholic pancreatitis. Gallstones were associated with a higher rate of recurrent pancreatitis, while undergoing cholecystectomy was associated with a reduction in this rate.

OBJECTIVES: One consequence of social distancing during the coronavirus disease 2019 (COVID-19) pandemic was an increase in alcohol use disorders. We postulated that this would be associated with a rise in alcohol-related gastrointestinal and liver disease. METHODS: Using Explorys Inc., an aggregate of electronic health records from US health care systems from 1999 to June 2021, we identified patients with "alcoholic hepatitis," "inflammation of pancreas caused by alcohol," and "alcoholic gastritis," based on Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT). We compared patients utilizing health care during the pandemic to those before it. RESULTS: We identified 8,445,720 patients treated from June 21, 2020 to June 20, 2021 ("COVID cohort") and 65,587,860 patients treated before this ("pre-COVID cohort"). African American patients were more likely to be treated for all causes during COVID-19 [odds ratio (OR): 1.65; P <0.0001]. Alcoholic hepatitis (OR: 2.77), alcoholic pancreatitis (OR: 3.67), and alcoholic gastritis (OR: 1.70) (for each, P <0.0001) were more likely in all patients in the COVID cohort. African Americans in the COVID cohort were more likely to be diagnosed with alcoholic hepatitis (OR: 2.63), alcoholic pancreatitis (OR: 2.17), and alcoholic gastritis (OR: 3.09) [for each, P <0.0001]. CONCLUSIONS: The prevalence of alcohol-related liver and gastrointestinal disease increased during COVID-19. We suspect these increases are associated with increased alcohol use disorder resulting from the stress of social isolation. These data suggest COVID-19 disproportionately affected African Americans in overall health care utilization and increased burden of alcoholic gastrointestinal and liver disease.

BACKGROUND: Chronic pancreatitis (CP) is a risk factor for pancreatic ductal adenocarcinoma (PDAC); nevertheless, the true incidence of PDAC in CP patients in the United States remains unclear. AIMS: We evaluated the risk of developing PDAC two or more years after a new diagnosis of CP. METHODS: Retrospective study of veterans from September 1999 to October 2015. A three-year washout period was applied to exclude patients with preexisting CP and PDAC. PDAC risk was evaluated in patients with new-diagnosis CP and compared with controls without CP using Cox-proportional hazards model. CP, PDAC, and other covariates were extracted using ICD-9 codes. RESULTS: After exclusions, we identified 7,883,893 patients [new-diagnosis CP - 21,765 (0.28%)]. PDAC was diagnosed in 226 (1.04%) patients in the CP group and 15,858 (0.20%) patients in the control group (p < 0.001). CP patients had a significantly higher PDAC risk compared to controls > 2 years [adjusted hazard ratio (HR) 4.28, 95% confidence interval (CI) 3.74-4.89, p < 0.001], 5 years (adjusted HR 3.32, 95% CI 2.75-4.00, p < 0.001) and 10 years of follow-up (adjusted HR 3.14, 95% CI 1.99-4.93, p < 0.001), respectively. By multivariable analysis, age (odds ratio 1.02, 95% CI 1.00-1.03, p = 0.03), current smoker (odds ratio 1.67, 95% CI 1.02-2.74, p = 0.042), current smoker + alcoholic (odds ratio 2.29, 95% CI 1.41-3.52, p < 0.001), and diabetes (odds ratio 1.51, 95% CI 1.14-1.99, p = 0.004) were the independent risk factors for PDAC. CONCLUSION: Our data show that after controlling for etiology of CP and other cofactors, the risk of PDAC increased in CP patients after two years of follow-up, and risk was consistent and sustained beyond 5 years and 10 years of follow-up.

INTRODUCTION: Although coexistence of alcohol-related liver disease (ALD) and pancreatitis (ALP) is seen in clinical practice, a clear understanding of the overlap between these diseases is lacking. Moreover, the relative risks for certain population groups have not been studied. We determined the prevalence and coexistence of ALD and ALP in patients with an alcohol use disorder using retrospective analysis of a large patient cohort from Western Pennsylvania. We specifically emphasized the analysis of underrepresented populations, including women and blacks. METHODS: We identified all unique patients who received care in UPMC health system during 2006-2017 with at least one International Classification of Diseases versions 9 and/or 10 codes for alcohol misuse, ALD and pancreatitis. We noted their sex, race and age of first diagnosis and duration of contact. RESULTS: Among 89,774 patients that fit our criteria, the prevalence of ALD, ALP and coexistent ALD and ALP in patients with alcohol misuse was 11.7%, 7.4% and 2.5%, respectively. Prevalence of ALP in ALD was 16.4%, and ALD in ALP was 33.1%. Prevalence of ALP in ALD was slightly more prevalent in women (18.6% vs. 15.6%, p < 0.001). Prevalence of ALP in ALD was 2-4 folds greater in blacks than other races. DISCUSSION: A sizeable fraction of patients with ALD or ALP has coexistent disease. This is the first study to identify that blacks are at a higher risk for ALP in the presence of ALD. Future studies should define the clinical impact of coexistent disease on clinical presentation and short- and long-term outcomes.

BACKGROUND/OBJECTIVES: In chronic pancreatitis (CP), progressive fibrosis of the pancreas leads to exocrine and endocrine insufficiency and, finally, to pancreatic burnout. Alcohol consumption is associated with fibrosis in the pancreas and the liver, and the activation of stellate cells plays a central role in the induction of fibrosis in both organs. However, the relationship between pancreatic burnout and liver cirrhosis (LC) is still poorly understood in patients with alcoholic CP (ACP). METHODS: We performed a single-center, retrospective, cross-sectional study with 537 CP patients. We analyzed the clinical presence of early and advanced pancreatic burnout and stated LC in cases of typical alterations in histology, liver stiffness measurement, cross-sectional imaging, or ultrasound. We analyzed further clinical parameters. RESULTS: The frequency of advanced pancreatic burnout was 6.5% for ACP (20/306) and 4% for non-ACP (8/206; p = 0.20; χ2 test). Advanced pancreatic burnout was not associated with the amount of alcohol consumption (p = 0.34) but with the disease duration (p = 0.0470) and rate of calcification (p = 0.0056). Furthermore, advanced pancreatic burnout was associated with LC (p < 0.0001) but cannot be explained by the amount of alcohol consumption. In ACP with alcohol consumption >80 g/day, an isolated LC was significantly more frequently detectable (14%, without pancreatic burnout) than an isolated advanced pancreatic burnout (1%, without LC). These results were confirmed by multivariable analyses. CONCLUSIONS: We identified a close association between LC and pancreatic burnout. The disease duration positively correlates with the development of pancreatic burnout. The liver seems to be more vulnerable to alcohol than the pancreas.

BACKGROUND/OBJECTIVES: Alcohol is the most common etiology of recurrent acute pancreatitis and chronic pancreatitis. The extent and timing of drinking that increases the transient risk of acute pancreatitis is yet unknown. METHODS: We designed a case-crossover study to determine the effective hazard period of drinking in relation to episodes of pancreatitis. We aim to evaluate the dose-response relationship between excess drinking and pancreatitis comparing the extent of drinking during case and control periods from the same individual. We aim to recruit 160 patients hospitalized with acute pancreatitis, whose AUDIT-C score reaches 3 or higher. Interviews of each enrolled patient to define their 15-day history of alcohol consumption employing the timeline follow-back method. Long-term drinking and smoking will be investigated as modifiers of the impact of short-term excess drinking. Patients are followed-up for evaluation of usual alcohol consumption during asymptomatic periods following the index hospitalization. Blood and urine specimens are collected while the patients are hospitalized and during a standard-of-care follow-up visit. RESULTS: We have recruited 31 patients to date, with a median age of 33 years. Females and non-White participants make up 26% and 35% of the enrolled population, respectively. Forty-eight % of patients have had a prior history of acute pancreatitis. CONCLUSIONS: Our study will shed light on the impact of short-term changes in drinking on triggering acute pancreatitis. It will provide data on other covarying factors of drinking and behaviors changes after 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.

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.

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.

INTRODUCTION: Vascular complications such as venous thrombosis (VT) and pseudoaneurysm are not uncommon in patients with chronic pancreatitis (CP). The aim of this study to was to evaluate the prevalence and risk factors for vascular complications in patients with CP. METHODS: A retrospective analysis of a prospectively maintained database of patients with CP presenting from January 2002 to August 2019 was performed. Venous thrombosis and pseudoaneurysm were identified using radiological imaging, and their risk factors were identified using multivariate Cox-proportional hazards. RESULTS: Of 1363 patients with CP, 166 (12.2%) had vascular complications. Isolated VT was present in 132, pseudoaneurysm in 17, and both in 17 patients. They were more commonly seen in males and alcoholic CP (ACP), and less commonly in patients with pancreatic atrophy and calcification. It involved the vessels in the closest proximity to the pancreas, VT most commonly involving the splenic vein whereas pseudoaneurysm most commonly involved the splenic artery. Alcoholic CP [odds ratio (OR) 2.1, p = 0.002], pseudocyst (OR 4.6, p < 0.001) and inflammatory head mass (OR 3.1, p = 0.006) were independent risk factors for VT, whereas ACP (OR 3.49, p = 0.006) and pseudocyst (OR 3.2, p = 0.002) were independent risk factors for pseudoaneurysm. Gastrointestinal bleed occurred in 3.5% patients, and more commonly in patients with pseudoaneurysm than VT (64.7% vs 15.9%), and in patients with ACP in comparison to other etiologies (p < 0.001). CONCLUSION: Vascular complications are a common complication of CP, VT being more frequent than pseudoaneurysm. Pseudocyst and ACP are independent risk factors for the development of vascular complications.

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.

Objective: To analyze the incidence of acute alcoholic pancreatitis and of severe alcoholic liver disease (ALD) and its association with per capita alcohol consumption with identification of both alcoholic cirrhosis (AC) and severe alcoholic hepatitis (AH), in a population-based setting.Methods: A search was undertaken in diagnoses database for diagnostic codes in order to find patients hospitalized with incident acute alcoholic pancreatitis (AP) and alcoholic liver disease in Iceland in 2001-2015. Diagnoses were verified in all patients who were retrospectively reviewed. Those with ALD had either AC or AH. Alcohol sales during the study period were obtained from Statistics Iceland.Results: Overall, 273 patients with acute AP, mean age at diagnosis 50 (14) years, 74% males and 159 patients with ALD, mean age 57 (11) years, 73% males, were identified. Mean per capita alcohol consumption was 6.95 (0.4) liters and increased by 21% over the study period. The annual incidence of AP increased from 4.2 per 100.000 to 9.5 and ALD from 1.6 to 6.1 per 100.000. Trend analysis showed a significant annual increase of 7% (RR 1.07, 95%CI 1.04-1.10) for AP and an annual increase of 10.5% (RR 1.10, 95%CI 1.06-1.15) for ALD. The increase was only significant in males.Conclusions: Increase per capita alcohol consumption over a 15 year study period was associated with an increase in the incidence of severe alcoholic liver disease and alcohol-related acute pancreatitis in males but not in females.

BACKGROUND/OBJECTIVES: In Finland the incidence of chronic pancreatitis (CP) is high compared to that in most European countries. Recent epidemiological data is lacking. Our aim was to investigate the current epidemiologic and behavioural data on CP patients in Finland. METHODS: CP patients according to M-ANNHEIM criteria in Tampere University Hospital (TAUH) during 2014-2015 were included. Aetiology, time from diagnosis, pancreatic function, treatment, complications, smoking, alcohol consumption (AUDIT) and quality of life (QoL) (QLQ C30, PAN26) were gathered. RESULTS: 235 CP patients (57 (26-88) years, 65% men) were included. Time since diagnosis was 5.5 (1-41) years. Aetiology was alcohol in 67%, and smoking contributed in 54%. Of these patients 78% continued smoking and 58% continued to consume alcohol even after CP diagnosis. CP related complications were common. Pseudocysts were more common in alcohol related CP than in non-alcohol related CP (60% vs. 38%, p < 0.05). Reported QoL and pain were worse in the CP patients than in controls. Alcohol consumption differed from that of the Finnish population; the CP patients were either total abstainers or heavy alcohol consumers. CONCLUSIONS: CP constitutes a great burden on the health care system and on the patients. The patients frequently develop complications and symptoms and their QoL is inferior to that of controls. The most important measure to halt the progression of CP would be to prevent acute phases and for patients to stop smoking, which does not happen in many CP patients. It would be beneficial to increase awareness among CP patients and medical professionals.

BACKGROUND: Genetic predisposition plays an important role in the development of alcoholic pancreatitis (AP), with previous studies suggesting that genetics variants in certain genes, such asCYP2E1 and CTRC, partially explain individual susceptibility to this disease. Therefore, the aim of this work was to conduct a systematic review and meta-analysis of existing studies that analyzed how polymorphisms within CYP2E1 and CTRC genes influence the risk of AP. MATERIAL AND METHODS: We performed a systematic review of studies that analyzed the genotype distribution of CYP2E1 and CTRC allelic variants among patients with AP and a group of controls. A meta-analysis was conducted using a random effects model. Odds ratios (ORs) and their confidence intervals (CIs) were calculated. RESULTS: The T allele of theCTRC 180 C > T variant was significantly more prevalent among patients with AP compared to all controls (OR = 1.79, 95% CI = 1.43-2.24; P < 0.00001) and healthy subjects (OR = 1.84, 95% CI = 1.46-2.31; P < 0.00001). The Trp variant of CTRC Arg254Trp polymorphism was also more prevalent in patients with AP; however, these results were not significant after excluding one study. We found no clear evidence that CYP2E1-DraI or of CYP2E1-RsaI/PstI polymorphisms modulate the risk of developing AP. CONCLUSIONS: Our meta-analysis supports that the T allele ofCTRC 180C > T polymorphisms modulates the risk of alcoholic pancreatitis. No clear evidence was found for the remaining SNPs being associated with this disease.

Alcohol is a major cause of acute and chronic pancreatitis. There have been some recent advances in the understanding of the mechanisms underlying alcoholic pancreatitis, which include perturbation in mitochondrial function and autophagy and ectopic exocytosis, with some of these cellular events involving membrane fusion soluble N-ethylmaleimide-sensitive factor receptor protein receptor proteins. Although new insights have been unraveled recently, the precise mechanisms remain complex, and their finer details have yet to be established. The overall pathophysiology of pancreatitis involves not only the pancreatic acinar cells but also the stellate cells and duct cells. Why only some are more susceptible to pancreatitis and with increased severity, while others are not, would suggest that there may be undefined protective factors or mechanisms that enhance recovery and regeneration after injury. Furthermore, there are confounding influences of lifestyle factors such as smoking and diet, and genetic background. Whereas alcohol and smoking cessation and a generally healthy lifestyle are intuitively the advice given to these patients afflicted with alcoholic pancreatitis in order to reduce disease recurrence and progression, there is as yet no specific treatment. A more complete understanding of the pathogenesis of pancreatitis from which novel therapeutic targets could be identified will have a great impact, particularly with the stubbornly high fatality (>30%) of severe pancreatitis. This review focuses on the susceptibility factors and underlying cellular mechanisms of alcohol injury on the exocrine pancreas.

BACKGROUND/OBJECTIVES: Carboxyl ester lipase is a pancreatic enzyme encoded by CEL, an extremely polymorphic human gene. Pathogenic variants of CEL either increases the risk for chronic pancreatitis (CP) or cause MODY8, a syndrome of pancreatic exocrine and endocrine dysfunction. Here, we aimed to characterize a novel duplication allele of CEL (CEL-DUP2) and to investigate whether it associates with CP or pancreatic cancer. METHODS: The structure of CEL-DUP2 was determined by a combination of Sanger sequencing, DNA fragment analysis, multiplex ligation-dependent probe amplification and whole-genome sequencing. We developed assays for screening of CEL-DUP2 and analyzed cohorts of idiopathic CP, alcoholic CP and pancreatic cancer. CEL protein expression was analyzed by immunohistochemistry. RESULTS: CEL-DUP2 consists of an extra copy of the complete CEL gene. The allele has probably arisen from non-allelic, homologous recombination involving the adjacent pseudogene of CEL. We found no association between CEL-DUP2 carrier frequency and CP in cohorts from France (cases/controls: 2.5%/2.4%; P = 1.0), China (10.3%/8.1%; P = 0.08) or Germany (1.6%/2.3%; P = 0.62). Similarly, no association with disease was observed in alcohol-induced pancreatitis (Germany: 3.2%/2.3%; P = 0.51) or pancreatic cancer (Norway; 2.5%/3.2%; P = 0.77). Notably, the carrier frequency of CEL-DUP2 was more than three-fold higher in Chinese compared with Europeans. CEL protein expression was similar in tissues from CEL-DUP2 carriers and controls. CONCLUSIONS: Our results support the contention that the number of CEL alleles does not influence the risk of pancreatic exocrine disease. Rather, the pathogenic CEL variants identified so far involve exon 11 sequence changes that substantially alter the protein's tail region.

OBJECTIVE: Concomitant occurrence of alcoholic chronic pancreatitis (ACP) and alcoholic liver cirrhosis (ALC) is rare with few reported cases. The present study aimed to identify the potential risk factors of chronic pancreatitis (CP) and liver cirrhosis (LC) in ALC patients and ACP patients, respectively. METHODS: A retrospective analysis was performed on 536 patients with CP and 647 ALC patients without CP (Group A). Among the 536 CP patients, 213 ACP cases were divided into two groups: ACP with LC (Group B, n = 52) and ACP without LC (Group C, n = 161). A comparison between Group A and B was carried out to identify the potential risk factors of CP in ALC patients, while Group B and C were compared to determine the independent risk factors of LC in ACP patients. RESULTS: Concomitant occurrence of ACP and ALC accounted for 24.4% (52/213) in this cohort. Significant risk factors for CP in ALC patients included smoking [odds ratio (OR), 2.557; 95% confidence interval (CI): 1.531-5.489; P = 0.003] and multiple bouts of acute pancreatitis (OR, 4.813; 95% CI: 3.625-12.971; P < 0.001). Hepatitis B virus (HBV) infection (OR, 4.237; 95% CI: 1.742-7.629; P = 0.012) was the only independent risk factor associated with LC in ACP patients. CONCLUSION: HBV infection exacerbated liver damage in ACP patients. Alcoholic patients who smoked and suffered from ongoing bouts of acute pancreatitis are prone to develop CP.

OBJECTIVES: The aim of this study was to assess the occurrence of new-onset diabetes mellitus (DM) after chronic pancreatitis (CP) diagnosis via systematic review and meta-analysis. METHODS: A systematic review of literature and meta-analysis of relevant reports were performed. The primary outcome measures studied were newly diagnosed DM and DM treated with insulin. For the binary outcomes, pooled prevalence and 95% confidence interval (CI) were calculated. METHODS: Fifteen studies involving 8970 patients were eligible. The incidence of new-onset DM after CP diagnosis was 30% (95% CI, 27%-33%). Among all patients, 17% (95% CI, 13%-22%) developed insulin-dependent new-onset DM. The prevalence of newly diagnosed DM after CP diagnosis increased from 15% within 36 months to 33% after 60 months. The proportion of alcoholic CP, sex, age, and body mass index had minimal effect on the studied outcomes. CONCLUSIONS: This systematic review identified a clinically relevant risk of new-onset DM after CP diagnosis. Therefore, patients should be informed of the risk of DM and monitored.
