Abstract
OBJECTIVES The association between the use of statins and the incidence of acute pancreatitis (AP) has yielded inconsistent findings. While statins have been implicated as an aetiology for drug-induced pancreatitis, more recent studies have found statin use is associated with a reduced risk of pancreatitis. We sought to examine the association between the use of any statin medications and the risk of AP using large real-world data. DESIGN All data were collected retrospectively, but individuals were prospectively followed forward in time to determine the outcome of interest using International Classification of Diseases, 10th Revision, Clinical Modification codes indicating a diagnosis of AP. A stratified Cox proportional hazards regression model was conducted to examine the association of statins use with AP. SETTINGS Merative MarketScan claims database 2017-2020. PARTICIPANTS Individuals who filled any statin prescriptions with at least 80% proportion of days covered between 1 January 2017 and 31 December 2017 and were continuously enrolled in the database from 2016 to 2020. We also identified non-users of statins and constructed multiple strata of individuals based on the 14 confounders of interest. RESULTS Among 1 695 914 individuals, 226 314 had filled their statins prescription during the study period. Unadjusted incidence rates of AP generally showed higher rates among statins users. The unadjusted incidence rate and 95% CI per 1000 person-years of follow-up was 0.63 (95% CI: 0.61 to 0.66) for non-statin users, versus 0.92 (95% CI: 0.86 to 0.98) for statins users. However, a stratified Cox proportional hazards regression analysis yielded a HR of 0.92 (95% CI: 0.84 to 1.01) for statins users, indicating no difference between the two groups. CONCLUSIONS In this large real-world analysis, use of statins was not associated with a higher risk of AP in this US healthcare setting.

Pharmacological and Endoscopic Interventions for Prophylaxis of Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis. Gastroenterology Res 2023; 16:149-156.

Abstract
Background Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) represents the most common serious complication after endoscopic retrograde cholangiopancreatography (ERCP). Rectal non-steroidal anti-inflammatory drugs (NSAIDs) and pancreatic duct stenting (PDS) are the prophylactic interventions with more evidence and efficacy; however, PEP still represents a significant source of morbidity, mortality, and economic burden. Chronic statin use has been proposed as a prophylactic method that could be cheap and relatively safe. However, the evidence is conflicting. We aimed to evaluate the impact of endoscopic and pharmacological interventions including chronic statin and aspirin use, on the development of PEP. Methods A retrospective cohort study evaluated consecutive patients undergoing ERCP at John H. Stroger, Jr. Hospital of Cook County in Chicago from January 2015 to March 2018. Univariate and multivariate analyses were performed using logistic regression. Results A total of 681 ERCPs were included in the study. Twelve (1.76%) developed PEP. Univariate, multivariate, and subgroup analyses did not show any association between chronic statin or aspirin use and PEP. PDS and rectal indomethacin were protective in patients undergoing pancreatic duct injection. Pancreatic duct injection, female sex, and younger age were associated with a higher risk. History of papillotomy was associated with lower risk only in the univariate analysis (all P values < 0.05). Conclusion Chronic use of statins and aspirin appears to add no additional benefit to prevent ERCP pancreatitis. Rectal NSAIDs, and PDS after appropriate patient selection continue to be the main prophylactic measures. The lower incidence at our center compared with the reported data can be explained by the high rates of rectal indomethacin and PDS, the use of noninvasive diagnostic modalities for patient selection, and the expertise of the endoscopists.

Abstract
Chronic pancreatitis (CP) is a chronic progressive inflammatory disease of the pancreas, caused by multiple factors and accompanied by irreversible impairment of pancreatic internal and external secretory functions. Pathologically, atrophy of the pancreatic acini, tissue fibrosis or calcification, focal edema, inflammation, and necrosis are observed. Clinical manifestations include recurrent or persistent abdominal pain, diarrhea, emaciation, and diabetes. In addition, CP is prone to develop into pancreatic cancer(PC) due to persistent inflammation and fibrosis. The disease course is prolonged and the clinical prognosis is poor. Currently, clinical treatment of CP is still based on symptomatic treatment and there is a lack of effective etiological treatment. Encouragingly, experiments have shown that a variety of active substances have great potential in the etiological treatment of chronic pancreatitis. In this paper, we will review the pathogenesis of CP, as well as the research progress on anti-inflammatory and anti-fibrotic therapies, which will provide new ideas for the development of subsequent clinical studies and formulation of effective treatment programs, and help prevent CP from developing into pancreatic cancer and reduce the prevalence of PC as much as possible.

Abstract
BACKGROUND Patients with acute pancreatitis (AP) have at least a 2-fold higher risk for developing postpancreatitis diabetes mellitus (PPDM). No therapies have prevented PPDM. Statins were demonstrated to possibly lower the incidence and severity of AP but have not been studied to prevent PPDM. METHODS Data from a commercial insurance claim database (Optum Clinformatics) were used to assess the impact of statins on patients without pre-existing DM admitted for a first episode of AP in 118,479 patients. Regular statin usage was defined as filled statin prescriptions for at least 80% of the year prior to AP. The primary outcome was defined as PPDM. We constructed a propensity score and applied inverse probability of treatment weighting to balance baseline characteristics between groups. Using Cox proportional hazards regression modeling, we estimated the risk of PPDM, accounting for competing events. RESULTS With a median of 3.5 years of follow-up, the 5-year cumulative incidence of PPDM was 7.5% (95% confidence interval [CI], 6.9% to 8.0%) among regular statin users and 12.7% (95% CI, 12.4% to 12.9%) among nonusers. Regular statin users had a 42% lower risk of developing PPDM compared with nonusers (hazard ratio, 0.58; 95% CI, 0.52 to 0.65; P < .001). Irregular statin users had a 15% lower risk of PPDM (hazard ratio, 0.85; 95% CI, 0.81 to 0.89; P < .001). Similar benefits were seen with low, moderate, and high statin doses. CONCLUSIONS In a large database-based study, statin usage reduced the risk of developing DM after acute pancreatitis. Further prospective studies with long-term follow-up are needed to study the impact of statins on acute pancreatitis and prevention of PPDM.

Abstract
OBJECTIVES Quantify the risk of drug-induced pancreatitis (DIP) from angiotensin-converting enzyme inhibitors (ACEis) and 3-hydroxy-3-methyl-glutaryl-CoA reductase inhibitors (statins). METHODS Retrospective cohort analysis using IBM Explorys (1999-2019), a pooled, deidentified clinical database of more than 63 million patients across the United States. Odds ratios were calculated to determine the risk of DIP from ACEi, statins, and both medications together. χ2 testing assessed the relationship between age, sex, ethnicity, insurance status, and mortality among patients with DIP from ACEi, statins, or both combined. RESULTS Acute pancreatitis (AP) was found in 280,740 patients. Odds ratios for ACEi, statins, and both combined were 6.12, 4.97, and 5.72, respectively. Thirty-eight percent of all-cause AP occurs in adults older than 65 years. Acute pancreatitis from ACEi and statins occurs in 49% and 56% of patients older than 65 years, respectively. Men and patients older than 65 years are at higher risk of DIP from ACEi and statins. Patients on Medicaid are at higher risk of DIP from statins, and Asian patients are at highest risk of DIP from ACEi. CONCLUSIONS We found that ACEi and statins increase the odds of DIP. Although ACEis and statins are critical medications for many patients, clinicians should consider using alternatives in patients with AP of unclear etiology.

Abstract
BACKGROUND There is limited evidence on the role of chronic statin therapy in the prevention of acute pancreatitis after ERCP. The aim of this meta-analysis was to evaluate the efficacy of statins in the prophylaxis of post-ERCP pancreatitis. RESEARCH DESIGN AND METHODS Bibliographic search was performed through May 2020. The primary outcome was post-ERCP pancreatitis rate. An additional endpoint was the rate of severe pancreatitis. RESULTS Nine studies, of which 1 prospective and 8 retrospective series, with 9374 patients were included. Baseline clinical and technical features were well balanced between the two study groups. Overall, pooled rate of post-ERCP pancreatitis was 4.8% (3.2%-6.4%) in the statin group and 7.1% (5.9%-8.3%) in the control group, with no difference in terms of pancreatitis rate (odds ratio 0.66, 95% confidence interval 0.43-1.02). This finding was confirmed in the multivariate analysis adjusted for several clinical and technical characteristics (adjusted odds ratio 0.68, 0.40-1.15). No difference was observed between the two study groups in terms of severe pancreatitis rate (odds ratio 1.07, 0.61-1.89). CONCLUSIONS Our meta-analysis seems to suggest the non-superiority of chronic statin therapy in preventing post-ERCP pancreatitis.
