RESUMEN
INTRODUCTION: Opioids used to manage severe pain in acute pancreatitis (AP) might exacerbate the disease through effects on gastrointestinal and immune functions. Methylnaltrexone, a peripherally acting µ-opioid receptor antagonist, may counteract these effects without changing analgesia. METHODS: This double-blind, randomized, placebo-controlled trial included adult patients with AP and systemic inflammatory response syndrome at 4 Danish centers. Patients were randomized to receive 5 days of continuous intravenous methylnaltrexone (0.15 mg/kg/d) or placebo added to the standard of care. The primary end point was the Pancreatitis Activity Scoring System score after 48 hours of treatment. Main secondary outcomes included pain scores, opioid use, disease severity, and mortality. RESULTS: In total, 105 patients (54% men) were randomized to methylnaltrexone (n = 51) or placebo (n = 54). After 48 hours, the Pancreatitis Activity Scoring System score was 134.3 points in the methylnaltrexone group and 130.5 points in the placebo group (difference 3.8, 95% confidence interval [CI] -40.1 to 47.6; P = 0.87). At 48 hours, we found no differences between the groups in pain severity (0.0, 95% CI -0.8 to 0.9; P = 0.94), pain interference (-0.3, 95% CI -1.4 to 0.8; P = 0.55), and morphine equivalent doses (6.5 mg, 95% CI -2.1 to 15.2; P = 0.14). Methylnaltrexone also did not affect the risk of severe disease (8%, 95% CI -11 to 28; P = 0.38) and mortality (6%, 95% CI -1 to 12; P = 0.11). The medication was well tolerated. DISCUSSION: Methylnaltrexone treatment did not achieve superiority over placebo for reducing the severity of AP.
RESUMEN
AIM: To study social disparity in acute pancreatitis (AP) and chronic pancreatitis (CP).We also aimed at exploring whether an interaction exists between alcohol intake and socioeconomic factors. METHODS: Prospective cohort study based on data from 271 696 men and women participating in the Danish National Health Surveys 2010, and 2013. Information on alcohol and smoking parameters, body mass index (BMI), diet, and education, were self-reported and information on family income was obtained from administrative registers. Outcome variables (acute and chronic pancreatitis) were obtained from national health registers. RESULTS: The incidence rate ratio (IRR) of developing AP and CP increased with decreasing family income. Compared to participants in the highest income quintile, participants in the lowest income quintile had 43 (95% CI: 14-80%), 99 (95% CI: 26-214%), and 56% (95% CI: 26-94%) higher incidence rates of AP, CP, and all pancreatitis, respectively. The associations persisted after adjustment for alcohol intake, smoking, BMI, and diet.Likewise, participants with only primary school education had an IRR for an AP of 1.30 (95% CI: 1.06-1.59) compared to those with higher education after adjustment for baseline year, age, and sex. We found no interactions between alcohol intake and income or between alcohol intake and education in relation to neither AP, CP, nor all pancreatitis. CONCLUSION: This large prospective population study showed a significant social disparity in incidence rates of pancreatitis by family income, with higher rates among those with the lowest income and education independent of risk factors such as alcohol intake, smoking, BMI, and diet.

Chronic pancreatitis (CP) is the end-stage of continuous inflammation and fibrosis in the pancreas evolving from acute- to recurrent acute-, early, and, finally, end-stage CP. Currently, prevention is the only way to reduce disease burden. In this setting, early detection is of great importance. Due to the anatomy and risks associated with direct sampling from pancreatic tissue, most of our information on the human pancreas arises from circulating biomarkers thought to be involved in pancreatic pathophysiology or injury. The present review provides the status of circulating biomarkers involved in the development of and progression to CP.

BACKGROUND AND AIMS: Pancreatic walled-off necrosis (WON) carries significant mortality and morbidity risks, often necessitating intensive care unit (ICU) admission. This retrospective study aimed to evaluate whether routine biochemical parameters at the time of the index endoscopic procedure could predict ICU admission and 1-year mortality following endoscopic treatment of WON. MATERIALS AND METHODS: We retrospectively identified 201 consecutive patients who underwent endoscopic drainage for WON between January 1, 2010, and December 31, 2020. Associations between routine biochemical blood tests and outcomes were assessed using logistic regression models. RESULTS: Within 1 year of the index endoscopy, 31 patients (15.4%) died, and 40 (19.9%) were admitted to the ICU due to sepsis. Preoperative electrolyte disturbances were more prevalent among ICU-admitted patients and nonsurvivors. Hyperkalemia, hypoalbuminemia, and elevated urea were significant predictors of 1-year mortality, while hypernatremia, elevated serum creatinine, and hypoalbuminemia predicted ICU admission. Predictive models exhibited good discriminative ability, with an AUC of 0.84 (95% CI,0,75-0.93) for 1-year mortality and 0.86 (95%CI, 0.79-0.92) for ICU admission. CONCLUSIONS: Preoperative imbalances in routine blood tests effectively predict adverse outcomes in endoscopically treated WON patients.
