Plasmatic Oxidative and Metabonomic Profile of Patients with Different Degrees of Biliary Acute Pancreatitis Severity

(1) Background: Acute pancreatitis (AP) is an inflammatory process of the pancreas with variable involvement of the pancreatic and peripancreatic tissues and remote organ systems. The main goal of this study was to evaluate the inflammatory biomarkers, oxidative stress (OS), and plasma metabolome of patients with different degrees of biliary AP severity to improve its prognosis. (2) Methods: Twenty-nine patients with biliary AP and 11 healthy controls were enrolled in this study. We analyzed several inflammatory biomarkers, multifactorial scores, reactive oxygen species (ROS), antioxidants defenses, and the plasma metabolome of biliary AP and healthy controls. (3) Results: Hepcidin (1.00), CRP (0.94), and SIRI (0.87) were the most accurate serological biomarkers of AP severity. OS played a pivotal role in the initial phase of AP, with significant changes in ROS and antioxidant defenses relating to AP severity. Phenylalanine (p < 0.05), threonine (p < 0.05), and lipids (p < 0.01) showed significant changes in AP severity. (4) Conclusions: The role of hepcidin and SIRI were confirmed as new prognostic biomarkers of biliary AP. OS appears to have a role in the onset and progression of the AP process. Overall, this study identified several metabolites that may predict the onset and progression of biliary AP severity, constituting the first metabonomic study in the field of biliary AP.

Morbid Obesity Does Not Impact Mortality, Rate of Endoscopy in Patients With Biliary Acute Pancreatitis: A US Nationwide Analysis

Introduction: Morbid obesity (MO) is associated with increased mortality in various conditions including acute pancreatitis. Interventions are challenging in patients with MO due to higher prevalence of comorbidities that may affect airway and cardiopulmonary management. Biliary acute pancreatitis (BAP) is the most common etiology for acute pancreatitis in the US. Population-based studies on the effect of obesity on biliary acute pancreatitis are lacking. This study aimed to assess the impact of MO on outcomes of patients with BAP. Methods: Data was obtained from the Nationwide Inpatient Sample database for 2016 and 2017. Hospital discharges of patients 18 years and over with a principal diagnosis of BAP were included. This cohort was divided based on BMI into nonobese patients (BMI &lt;30) and morbidly obese (MO) patients (BMI &gt;/=40.0). Patients with BMI between 30.0–39.9 were excluded. Primary outcome was inpatient mortality. Secondary outcomes included rate of endoscopic procedures, length of hospital stay (LOS), total hospital charges (THC), discharge diagnoses of hypocalcemia, septic shock, acute renal failure (AKI) and acute respiratory failure (ARF). Multivariate regression analysis was used to adjust for patients’ sociodemographic factors, Charlson comorbidity index as well as hospital characteristics as confounders. Results: A total of 128995 hospitalizations were principally for BAP, with 75.7% and 12.0% of these patients classified as nonobese and MO respectively. There was a significantly higher proportion of females (66.1 vs 54.5%, p&lt;0.001) and lower mean age (50.1 vs 58.7 years, p&lt;0.001) in patients with MO. There was no significant difference in adjusted odds of mortality (aOR=1.34, 95% CI: 0.88 - 2.03, p=0.174), or rate of endoscopy (aOR 1.00 95% CI: 0.91 - 1.11, p=0.958), in MO compared with patients who were nonobese. However, MO patients had increased mean LOS of 0.8 days (95% CI: 0.5 - 1.0, p&lt;0.001), increased mean THC of $10760 (95% CI: 7077 - 14442, p&lt;0.001), increased odds of hypocalcemia (aOR=1.60, 95% CI: 1.22 - 2.09, p=0.001), septic shock (aOR=2.13, 95% CI: 1.39 - 3.25, p&lt;0.001), and AKI (aOR=1.48, 95% CI: 1.30 - 1.68, p&lt;0.001). Conclusion: Even though we did not find any significative difference in mortality, patients with MO appear to have and increased LOS and THC, as well as more complications like septic shock, AKI, and hypocalcemia. This calls for a greater recognition of this association for further research studies and to recognize this potential association during clinical practice.

Az akut pancreatitist követő kórházi visszavételi arány mint minőségi mutató

Összefoglaló. Bevezetés: Az akut pancreatitis az egyik leggyakoribb kórházi felvételt igénylő gastrointestinalis kórkép. A korai visszavételi arány egyrészt az ellátást jellemző minőségi mutató, másrészt az akut pancreatitis 1 éves mortalitásának legerősebb prognosztikai faktora. Célkitűzés: A korai visszavétel arányának, illetve okainak vizsgálata klinikánkon akut pancreatitis diagnózisával kezelt betegek körében. Módszerek: Retrospektív vizsgálatunkat azon 18 év feletti betegek körében végeztük, akiket a 2010. január és 2018. december közötti időszakban akut pancreatitis diagnózisával kezeltünk klinikánkon, és az első emissziótól számítva 30 napon belül újból felvételre kerültek. A betegek adatait az Akut Pancreatitis Regiszter és a betegnyilvántartó rendszer (MedSol ) segítségével gyűjtöttük össze. A biliaris, illetve nem biliaris akut pancreatitises eseteket hasonlítottuk össze az epidemiológiai adatok, a visszavétel oka, a visszavételig eltelt átlagos időtartam, és a visszavétel időtartama, valamint kimenetele vonatkozásában. Eredmények: Akut pancreatitis diagnózisával 647 beteg került felvételre. Közülük 28 beteg került újrafelvételre. A leggyakoribb okok között 1) peripancreaticus szövődmények, 2) epés panaszok és 3) az akut pancreatitis kiújulása szerepel. A biliaris és a nem biliaris pancreatitises eseteket összehasonlítva, a visszavétel oka epés panasz volt az előbbi csoport 65,5%-ában és az utóbbi 15%-ában. A középsúlyos pancreatitises esetek száma szignifikánsan magasabbnak adódott a nem biliaris csoportban. Következtetés: A középsúlyos/súlyos pancreatitises esetek aránya magasabb volt a nem biliaris pancreatitises csoportban. Biliaris pancreatitis esetén javasolt index-cholecystectomia végzése. Orv Hetil. 2021; 162(11): 413–418. Summary. Introduction: Acute pancreatitis is the leading cause of hospitalization among gastrointestinal diseases. The early readmission rate is a quality marker and the strongest prognostical factor of 1-year mortality of acute pancreatitis. Objective: To investigate the rate and cause of early readmission among patients treated with acute pancreatitis at our clinic. Methods: Our retrospective study was conducted among patients (>18 years) treated with acute pancreatitis between January 2010 and December 2018 at our clinic, by whom unplanned readmission happened <30 days from emission. Personal data were collected from the Hungarian Pancreas Registry. Data of biliary and non-biliary acute pancreatitis cases were compared concerning epidemiological data, cause of readmission, mean time elapsed until readmission, its duration and outcome. Results: 647 patients were diagnosed with acute pancreatitis. Of them, 28 patients had early readmission. The most common causes were 1) local pancreatic complications, 2) biliary and 3) recurrence of acute pancreatitis. By investigating the biliary and non-biliary pancreatitis cases separately, the cause of readmission was biliary in 65.5% and 15%, respectively. The number of moderately severe pancreatitis cases was significantly higher in the non-biliary group. Conclusion: The proportion of moderate/severe diseases was higher in the non-biliary pancreatitis group. In the case of biliary pancreatitis, it is suggested to perform index cholecystectomy.

Incidence and risk factors of oral feeding intolerance in acute pancreatitis: results from an international, multicenter, prospective cohort study

Background Inability to advance to an oral diet, or oral feeding intolerance, is a common complication in patients with acute pancreatitis associated with worse clinical outcomes. The factors related to oral feeding intolerance are not well studied. Objective We aimed to determine the incidence and risk factors of oral feeding intolerance in acute pancreatitis. Methods Patients were prospectively enrolled in the Acute Pancreatitis Patient Registry to Examine Novel Therapies in Clinical Experience (APPRENTICE), an international acute pancreatitis registry, between 2015 and 2018. Oral feeding intolerance was defined as worsening abdominal pain and/or vomiting after resumption of oral diet. The timing of the initial feeding attempt was stratified based on the day of hospitalization. Multivariable logistic regression was performed to assess for independent risk factors/predictors of oral feeding intolerance. Results Of 1233 acute pancreatitis patients included in the study, 160 (13%) experienced oral feeding intolerance. The incidence of oral feeding intolerance was similar irrespective of the timing of the initial feeding attempt relative to hospital admission day ( P = 0.41). Patients with oral feeding intolerance were more likely to be younger (45 vs. 50 years of age), men (61% vs. 49%) and active alcohol users (44% vs. 36%). They also had higher blood urea nitrogen (20 vs. 15 mg/dL; P<0.001) and hematocrit levels (41.7% vs. 40.5%; P = 0.017) on admission; were more likely to have a non-biliary acute pancreatitis etiology (69% vs. 51%), systemic inflammatory response syndrome of 2 or greater on admission (49% vs. 35%) and at 48 hours (50% vs. 26%;), develop pancreatic necrosis (29% vs. 13%), moderate to severe acute pancreatitis (41% vs. 24%) and have a longer hospital stay (10 vs. 6 days; all P<0.04). The adjusted analysis showed that systemic inflammatory response syndrome of 2 or greater at 48 hours (odds ratio 3.10; 95% confidence interval 1.83–5.25) and a non-biliary acute pancreatitis etiology (odds ratio 1.65; 95% confidence interval 1.01–2.69) were independent risk factors for oral feeding intolerance. Conclusion Oral feeding intolerance occurs in 13% of acute pancreatitis patients and is independently associated with systemic inflammatory response syndrome at 48 hours and a non-biliary etiology.
