Background and Objectives: The purpose of this study is to use contrast-enhanced computed tomography to categorize individuals with acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis according to the updated Atlanta classification, and to describe the kind of collections in these patients. After that, we'll determine how severe it is using the new Atlanta categorization. And using the BISAP clinical rating system, discuss the disease's clinical progression and severity. Ultimately, we hope to link these observations to improved patient care. Materials and Methods: The study period began June 2022 to May 2023, conducted at the Department of Radiodiagnosis, Dr. Patnam Mahender Reddy Institute of Medical Sciences, Chevella, Hyderabad, India. This prospective observational study took place in a hospital setting. The sample size for this study was 200 patients. Primary data was obtained by the investigator from patients diagnosed with acute pancreatitis and admitted to the surgery or medicine wards at our hospital for CT scans. Results: Patients in our study group tended to be male, and alcoholism was the leading cause of their condition. In addition, interstitial edematous pancreatitis and mild acute pancreatitis accounted for the vast majority of cases. They achieved favorable clinical outcomes with a BISAP score of less than 3. Acute necrotizing pancreatitis and interstitial edema were both classified as moderately severe. Necrotizing pancreatitis was the most common kind of the severe acute form. Clinical outcomes were unsatisfactory for the majority of these individuals. Grades in the moderately severe range lie between the mild and severe varieties. Clinical result was found to correlate positively with BISAP rating, and the updated Atlanta categorization. Conclusion: Acute pancreatitis imaging results can now be more uniformly described and recorded in clinical practice according to the new Atlanta classification system. Acute pancreatitis patients can now be more accurately triaged, predicted, and treated thanks to the integration of the new Atlanta classification and BISAP clinical grading. [ABSTRACT FROM AUTHOR]

High-density lipoprotein cholesterol (HDL-C) is reported as a biomarker of systemic inflammation and multi-organ failure (MOF), which has been rarely investigated in acute pancreatitis (AP), a frequent condition in the emergency department (ED). The objective was to study the predictive capacity of the decrease in HDL-C to the progression of MOF in AP in the ED; analyzing 114 patients with AP for one year in a longitudinal and prospective study, AP severity was obtained by the Atlanta classification, in relation to modified Marshall and Bedside Index for Severity in Acute Pancreatitis (BISAP) scores, and clinical and laboratory parameters in a 48 h hospital stay. The area under the receiver operating characteristic (ROC) curve was used to estimate the validity of the predictor and define optimal cut-off points. It was found that AP was classified as severe in 24.5%, mainly for biliary etiology (78.9%) and female sex (73.6%). As a biomarker, HDL-C decreased from 31.6 to 29.5 mg/dL in a 48 h stay (p < 0.001), correlating negatively with the increase in severity index > 2 and the modified Marshall (p < 0.032) and BISAP (p < 0.009) scores, finding an area under the ROC curve with a predictive capacity of 0.756 (95% CI, 0.614–0.898; p < 0.004) and a cut-off point of 28.5 mg/dL (sensitivity: 79%, specificity: 78%), demonstrating that the decrease in HDL-C levels serves as a useful indicator with a predictive capacity for MOF in mild to severe AP, during a 48 h hospital stay in the ED.

The CT features, clinical characteristics, severity of AP, and presence of persistent SIRS between the two groups were compared. Univariate and multivariate analyses were performed to determine the risk factors for predicting SIRS. The diagnostic performances of the risk factors were evaluated by receiver operating characteristic (ROC) curve analysis.Results: Among the 189 patients, 49.7% (94/189) had preexisting FL. On CT, AP patients with preexisting FL were more likely to develop necrosis (23.4% vs 10.5%, p=0.021), local complications (45.7% vs 29.5%, p=0.025) and persistent SIRS (59.6% vs 27.4%, p< 0.001). Multivariate analysis showed that preexisting FL (OR=2.863, 95% CI: 1.264– 6.486, p=0.012), APACHE II≥ 6 (OR=1.334, 95% CI: 1.117– 1.594, p=0.002), and MCTSI ≥ 4 (OR=1.489, 95% CI: 1.046– 2.119, p=0.027) could be independent risk factors for persistent SIRS. The areas under the ROC curve of preexisting FL, APACHE II, and MCISI in diagnosing AP patients with persistent SIRS were 0.664, 0.703, and 0.783, respectively.Conclusion: Patients with preexisting FL were more likely to develop necrosis and local complications on CT and present more severe AP and persistent SIRS. Preexisting FL can be an independent risk factor in predicting the presence of persistent SIRS in patients with AP.Keywords: acute pancreatitis, fatty liver, severity, systemic inflammatory response syndrome, Atlanta classification

Introduction: In this study, we aimed to examine the prognostic importance of the c - reactive protein (CRP)/albumin ratio in predicting acute necrotizing pancreatitis. Methods: The study included 100 patients diagnosed with acute interstitial pancreatitis and 50 patients diagnosed with necrotizing pancreatitis between 2015 and 2020, all over the age of 18. Results: The CRP/albumin ratio was higher in the acute necrotizing pancreatitis group compared to the interstitial pancreatitis group (94.0 vs 34.0; p <0.001, respectively). Multivariable analysis revealed CRP/albumin ratio [OR: 1.075 (1.029-1.123), p = 0.001], source of infection [OR: 4.698 (2.078-10.620), p < 0.001], and lactate dehydrogenase [OR: 1.006 (1.002-1.010), p = 0.004] to be significantly predictive of developing necrotizing pancreatitis. A prediction value of CRP/albumin ratio >70.6 was found to be a significant marker in predicting necrotizing pancreatitis (Sensitivity: 76.0%; Specificity: 85.4%; AUC: 0.881; p < 0.001). In addition, to demonstrate the nonlinear relationship between CRP/albumin and the probability of necrotizing pancreatitis, cubic spline regression analysis was applied, showing that the probability of necrotizing pancreatitis increased in relation to the increase of the CRP/albumin ratio. Conclusion: We conclude that the CRP/albumin ratio is a predictor of acute necrotizing pancreatitis. We believe that the CRP/albumin ratio is an inexpensive, sensitive, and easy-to-use predictor of acute necrotizing pancreatitis that can be used for both diagnosis and treatment follow-up.

A number of scoring systems were developed to prospectively predict the severity of acute pancreatitis so that early aggressive therapy can be initiated. The present study aimed to establish the role of red cell distribution width (RDW) and neutrophil lymphocyte ratio (NLR) as severity predictors of acute pancreatitis by comparing these parameters with the well-established Acute Physiological and Chronic Health Evaluation II (APACHE II) score. A prospective observational single-center cohort study was conducted on adult patients of acute pancreatitis. RDW, NLR, and APACHE II score were calculated at the time of admission. RDW and NLR were repeated at 24 h, 48 h, 72 h, and at 96 h. The primary outcome studied was the association of RDW and NLR with severity of acute pancreatitis. The sample size was 57 patients. The mean scores of RDW and NLR at admission, at 24 h, at 48 h, at 72 h, and at 96 h, were significantly greater than in moderately severe and severe acute pancreatitis, and the same was true for APACHE II score at admission. On comparing sensitivity, no significant difference was seen between RDW, NLR, and APACHE II score. Specificity of APACHE II was significantly higher when compared to RDW and NLR. Our study showed that RDW and NLR can be used as independent prognostic markers for predicting the severity of acute pancreatitis. However, APACHE II score continues to be the gold standard in this regard. [ABSTRACT FROM AUTHOR]

Objective: To compare the Glasgow scoring system and modified CTSI scoring system regarding its ability to predict the severe nature of acute pancreatitis according to the revised Atlanta classification in a tertiary care hospital in Pakistan. Study Design: Comparative cross-sectional study. Place and Duration of Study: General Surgery Department, Combined Military Hospital, Rawalpindi from July 2020 to Jul 2021. Methodology: Forty patients ranging from 30 to 70 years of age with acute pancreatitis, some of them were admitted to our hospital and others were received in the Emergency Department. Glasgow and modified CTSI scores were calculated for all cases. Results: Glasgow and CTSI scoring systems were compared according to the Atlanta Classification. The data in our study showed a mean Glasgow score of 2.475 ± 2.975, whereas the mean CTSI score was 5.575 ± 2.458. In predicting severe acute pancreatitis using the AUC graph, the CTSI scoring system had a higher accuracy (0.994) than Glasgow score (0.987). For mild and moderately severe acute pancreatitis, both Glasgow and CTSI showed significance (p<0.01). Conclusion: CTSI scoring is more accurate in detecting the severity of acute pancreatitis. Glasgow was close behind, but it is not an accurate indicator. [ABSTRACT FROM AUTHOR]

Introduction: There is an upsurge in the incidence of acute pancreatitis over the last few decades; although the case fatality rate has remained unchanged. This may either be due to increased incidence of gallstone disease or improvement in diagnostic modalities. It is a potentially life threatening disease with varying severity of presentation. Methods: This observational analytical study was conducted in the Department of General Surgery in our hospital for a period of one year. All patients of acute pancreatitis were included in the study as per inclusion & exclusion criteria. Observations and Results: Total 62 Patients were included in the study. Gall stones disease is the most common cause of acute pancreatitis. The mean age of the patients in the study was 39 years. 28 females and 34 male patients were present. 22 patients of the patients had severe disease as per Atlanta classification. Four out of these 22 severe pancreatitis patients expired. All patients in the severe pancreatitis group had mild to life threatening complications and pleural effusion was the most common followed by necrosis. There was notable difference in terms of hospital stay between mild group and severe group of AP. Conclusion: The clinician should be aware that acute pancreatitis can occur in any age group and gender due to different etiology. The severity of AP does not depend on etiology, age or gender and it is associated with significant morbidity and mortality. SAP can be diagnosed on clinicoradiological basis and appropriate management can be done in those patients.

In recent years, there have been further advances in understanding of the acute pancreatic inflammation and its complications. Among these are emerging concepts such as peripancreatic necrosis and main duct injury secondary to necrotizing pancreatitis. To remain relevant to the clinical teams, radiologists need to be aware of these advances in knowledge and their reports should provide key points of information that may impact patient management. This article provides an up to date review of acute pancreatitis.

Early diagnosis of severe acute pancreatitis (AP) is important to reduce morbidity and mortality. We investigated the association between the triglyceride and glucose index (TyG index) and the prognosis of severe AP (SAP). The TyG index was calculated as: ln [fasting triglycerides (mg/dL) x fasting plasma glucose (mg/dL)]/2. Multivariable logistic regression analyses were used to investigate the independent association between the TyG index and the severity of AP. In this study, 373 patients with AP were recruited from three hospitals. The TyG index was higher in the SAP group than in the non-SAP group. Further, the TyG index was higher than in patients admitted to an intensive care unit and those who died of AP. The TyG index was an independent predictive factor for SAP (odds ratio 7.14, 95% confidence interval 2.80–18.19). The area under the curve increased significantly, from 0.738 to 0.830, after adding the TyG index to a predictive SAP model. Our findings suggest that the TyG index is an independent prognostic factor in patients with AP and could be used as a simple prognostic indicator for SAP. [ABSTRACT FROM AUTHOR]

Background: We aimed to investigate the prognostic importance of platelet-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio(NLR) combination for patients diagnosed with acute pancreatitis and its relationship with mortality. Methods: This retrospective study was included 142 patients diagnosed with acute pancreatitis. Ranson, Atlanta and BISAP 0h, 24h and 48h scores of the patients were calculated by examining their patient files. The patients were divided into three groups as low-risk, medium-risk and high-risk patients according to their PLR and NLR levels. Results: The number of patients with acute pancreatitis complications such as necrotizing pancreatitis, acute renal failure, sepsis and cholangitis was significantly higher in the high-risk group compared to other groups. Mortality rate was found to be 90% in the high-risk group, 16% in the medium-risk group, and 1.9% in the low-risk group. The number of patients with a Ranson score of 5 and 6, a severe Atlanta score, a BISAP 0h score of 3 and 4, a BISAP 24h and 48h score of 4 and 5 was higher in the high-risk group compared to other groups. PLR-NLR combination, Atlanta and Ranson scores, and C-reactive protein level were determined to be independent risk factors predicting mortality in stepwise regression model. PLR-NLR combination had the highest area under curve value in terms of predicting acute pancreatitis prognosis and had a similar diagnostic discrimination with other scoring systems. Conclusions: In our study it was found that PLR-NLR combination had a similar prognostic importance with other scoring systems used to determine acute pancreatitis prognosis.

Coronavirus disease 2019 (COVID-19) typically presents with pulmonary symptoms. Extra-pulmonary symptomatology of COVID-19 has drawn significant attention. However, information about the incidence, course and outcomes of acute pancreatitis in these patients is still limited. [ABSTRACT FROM AUTHOR]

Aims of this study: Severe acute pancreatitis has been defined recently based on the persistence of organ failure at 48 hours of admission. The bedside index for severity in acute pancreatitis (BISAP) score, a simplified scoring system to predict severity of acute pancreatitis, is proposed to be useful in early risk stratification of acute pancreatitis. Our aim was to prospectively compare BISAP score with the already established acute physiology and chronic health evaluation II (APACHE II) and modified computed tomography severity index (CTSI) scores in predicting the severity of acute pancreatitis. Materials and methods: A total of 87 consecutive cases presenting with the first attack of acute pancreatitis were included in the study. Acute physiology and chronic health evaluation II and BISAP scores were calculated from the worst parameters in the first 24 hours, and modified CTSI was reported at 48 hours of admission. Receiver-operating characteristic (ROC) curves were plotted, and predictive accuracy of each score was calculated from the area under the curve. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for each score. Results: A total of 20 patients (23%) had severe acute pancreatitis with a total of 11 mortalities (12.64%), 10 of them in the severe acute pancreatitis group. Acute physiology and chronic health evaluation II, modified CTSI, and BISAP score all correlated well with each other. Modified CTSI and BISAP score also correlated with duration of hospital stay. Areas under the curve for APACHE II (≥8), modified CTSI (≥8), and BISAP score (≥2) were 0.826, 0.806, and 0.811, respectively, suggesting similar predictive accuracy. Conclusion: The BISAP score was similar to APACHE II and modified CTSI in terms of accuracy, sensitivity, specificity, and NPV. It is much easier to calculate and a useful risk stratification tool. It should be used for early triage and referral to a high dependency unit. [ABSTRACT FROM AUTHOR]

Acute pancreatitis (AP) is divided into two types: interstitial edematous and necrotizing. AP severity is classified clinically into mild, moderately severe, and severe, depending on the presence and persistence of organ failure and local or systemic complications. The revised Atlanta classification divides the clinical course of AP into an early (first week) and late phase (after first week) and the clinical phase determines the role of imaging. Imaging has a limited role in the early phase. In the early phase with typical presentations of AP, ultrasound is usually the only appropriate modality and is used for the detection of gallstones. CT and MRI are appropriate in the early phase in equivocal presentations. In the late phase (or at least 48-72 hours after presentation), CT and MRI play a primary role in the imaging of patients with AP for evaluation of etiology, complications, extent of disease, intervention, and follow-up; CT is particularly useful in patients with suspected acute hemorrhage. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is available in the text Objective: The aim of this study was to compare and validate the different classifications of severity in acute pancreatitis (AP) and to investigate which characteristics of the disease are associated with worse outcomes. Summary of Background Data: AP is a heterogeneous disease, ranging from uneventful cases to patients with considerable morbidity and high mortality rates. Severity classifications based on legitimate determinants of severity are important to correctly describe the course of disease. Methods: A prospective multicenter cohort study involving patients with AP from 23 hospitals in Spain. The Atlanta Classification (AC), Revised Atlanta Classification (RAC), and Determinant-based Classification (DBC) were compared. Binary logistic multivariate analysis was performed to investigate independent determinants of severity. Results: A total of 1655 patients were included; 70 patients (4.2%) died. RAC and DBC were equally superior to AC for describing the clinical course of AP. Although any kind of organ failure was associated with increased morbidity and mortality, persistent organ failure (POF) was the most significant determinant of severity. All local complications were associated with worse outcomes. Infected pancreatic necrosis correlated with high morbidity, but in the presence of POF, it was not associated to higher mortality when compared with sterile necrotizing pancreatitis. Exacerbation of previous comorbidity was associated with increased morbidity and mortality. Conclusion: The RAC and DBC both signify an advance in the description and differentiation of AP patients. Herein, we describe the complications of the disease independently associated to morbidity and mortality. Our findings are valuable not only when designing future studies on AP but also for the improvement of current classifications. [ABSTRACT FROM AUTHOR]

Abstract: Background and Aim: Severe acute pancreatitis (SAP) has considerable mortality and morbidity rates. Although many indices have been developed to classify the severity of acute pancreatitis (AP), an optimal method for predicting SAP has not been identified. The ratio of apolipoprotein B to A‐I (apoB/A‐I) is associated with metabolic syndrome and inflammatory status. This study investigated the association between severity of AP and serum apoB/A‐I ratio. Methods: Patients with AP were prospectively enrolled at Yonsei University Wonju College of Medicine from March 2015 to August 2016. The severity of AP was assessed according to the revised Atlanta classification criteria (Atlanta 2012). Results: Of 191 patients with AP, 134 (70.2%) had mild AP, 42 (22%) had moderately severe AP, and 15 (7.9%) had SAP; apoB/A‐I ratio was highest in patients with SAP (P = 0.001). The apoB/A‐I ratio was positively correlated with Atlanta classification, computed tomography severity index, and Bedside index for severity of AP. The apoB/A‐I ratio showed the highest predictive value for SAP in patients with AP compared with apolipoprotein B or apolipoprotein A‐I alone. Conclusion: Serum apoB/A‐I ratio appears to have value for predicting SAP in patients with AP. [ABSTRACT FROM AUTHOR]

Background/Objectives We aim to assess which tools for severity stratification in acute pancreatitis are used in today's daily clinical practice and to what extent the new Atlanta classification is being implemented by the medical community in Switzerland. Methods The heads of surgical, medical and emergency departments of Swiss hospitals ( n = 83) that directly treat patients with acute pancreatitis were given access to an online survey and asked to forward the questionnaire to their team. The questionnaire consisted of 16 items, including questions about the specialty background of the participants, the allocation of patients with AP, severity assessment, patient management, the role of imaging procedures, and future perspectives. Results A total of 233 participants from 63 hospitals responded (response rate, 74%). A vast majority of participants [198 (87%)] does assess severity. The most frequently used tools are the Ranson [108 (87%)] and APACHE II scores [28 (23%)]. A majority of the participants were not satisfied with the currently available tools to assess severity [130 (59%)]. A minority [15 (12%)] use the revised Atlanta classification to assess the degree of severity in AP. Conclusions The Ranson score remains the dominant risk stratification tool in clinical practice in Switzerland, followed by the APACHE II score. Other modern instruments, such as the Atlanta 2012 classification, have not yet earned broad recognition and have not reached daily practice. Further efforts must be made to expand physicians' awareness of their existence and significance. [ABSTRACT FROM AUTHOR]

Acute pancreatitis (AP) is an inflammatory disease of highly variable severity, ranging from mild cases with low mortality to severe cases with high mortality. Numerous biomarkers have been studied as potential early predictors of the severity of this disease so that treatment can be optimally tailored to prevent complications. We aim to present and discuss the most relevant biomarkers for early severity assessment in AP that have been studied to date. We review the current literature on biomarkers that have been used to predict the severity in AP. C-reactive protein (CRP) is still considered to be the gold standard, with a cut-off value of 150 mg/ml 48 h after disease onset. Other markers, including procalcitonin (PCT) and interleukin 6 (IL-6) have been implemented in some hospitals, but are not used on a routine basis. Most other markers, including acute phase proteins (LBP, SAA, PTX3), cytokines (Il-8, TNF-a, MIF), activation peptides of pancreatic proteases (TAP, CAPAP, PLAP), antiproteases (AAT, a2M), adhesion molecules (ICAM-1, selectins, E-cadherin) and leukocyte-derived enzymes (PA2, PMN-E) have shown some promising results but have not been routinely implemented. Furthermore, new and interesting biomarkers (Copeptin, TRX-1, Ang-2, E-2) have shown good results, but more research is needed to determine if they could play a role in the future. Various reasons why new markers for disease severity have not been adopted in daily routine include low accuracy, cumbersome laboratory techniques and high cost. Despite these difficulties, research is still very active in finding new markers to predict the severity of AP. [ABSTRACT FROM PUBLISHER]

Acute pancreatitis (AP) is a disease spectrum ranging from mild to severe with an unpredictable natural course. Majority of cases (80%) are mild and self-limiting. However, severe AP (SAP) has a mortality risk of up to 30%. Establishing aetiology and risk stratification are essential pillars of clinical care. Idiopathic AP is a diagnosis of exclusion which should only be used after extended investigations fail to identify a cause. Tenets of management of mild AP include pain control and management of aetiology to prevent recurrence. In SAP, patients should be resuscitated with goal-directed fluid therapy using crystalloids and admitted to critical care unit. Routine prophylactic antibiotics have limited clinical benefit and should not be given in SAP. Patients able to tolerate oral intake should be given early enteral nutrition rather than nil by mouth or parenteral nutrition. If unable to tolerate per-orally, nasogastric feeding may be attempted and routine post-pyloric feeding has limited evidence of clinical benefit. Endoscopic retrograde cholangiopancreatogram should be selectively performed in patients with biliary obstruction or suspicion of acute cholangitis. Delayed step-up strategy including percutaneous retroperitoneal drainage, endoscopic debridement, or minimal-access necrosectomy are sufficient in most SAP patients. Patients should be monitored for diabetes mellitus and pseudocyst., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2022.

Accurate diagnosis and description of the various findings in acute pancreatitis is important for treatment. The original Atlanta classification for acute pancreatitis sought to create a uniform system for classifying the severity of acute pancreatitis as well as common language to describe the various events that can occur in acute pancreatitis. The goal was to allow accurate communication between physicians using standardized language so correct treatment options could be used. Since that time, advances in the understanding of acute pancreatitis as well as improvements in both interventions and imaging have led to criticisms of the system and its abandonment by physicians. A 2007 revision of the Atlanta classifications sought to address many of these issues. This article will explain the changes to the Atlanta classification system and provide pictorial examples of the findings in acute pancreatitis as described by the Atlanta classification system.

Background: Both, acute and chronic pancreatitis represent complex disease patterns, whose effective treatment is based on structured diagnostics and therapy by a multi-professional team. There are different systems for an improved objectivity in the classification of the severity of the disease OBJECTIVES: Overview of the common classifications of acute and chronic pancreatitis., Materials and Methods: Literature research of currently used classifications of acute and chronic pancreatitis. Evaluation of the current chronic pancreatitis guideline., Results: For acute pancreatitis, the modified Atlanta Classification and the "determinant-based" classification are most widely used. These classifications are complemented by clinical risk scores such as the Marshall Score and the SOFA Score. In chronic pancreatitis, the image-based Cambridge classification was established. For clinical assessment further classifications such as the ABC classification and the M‑ANNHEIM classification are applied evaluating leading symptoms such as pain, exocrine and endocrine pancreatic insufficiency.

Background: The atherogenic index of plasma (AIP) reflects the levels of triglycerides (TG) and high-density lipoprotein (HDL) cholesterol. The purpose of this study was to assess the relationship between the AIP and severe acute pancreatitis (SAP). Materials and methods: Patients with acute pancreatitis (AP) were prospectively enrolled from March 2015 to June 2019. The severity of AP was classified according to the 2012 revised Atlanta classification. Mild and moderately severe AP were categorized as non-SAP. The AIP is calculated as log(TG/HDL). Results: A total of 323 patients were enrolled. The etiologies of AP were gallstone in 171 patients (52.9%), alcohol in 122 patients (37.8%), and hypertriglyceridemia in 30 patients (9.3%). Twenty-four patients (7.4%) were classified as SAP. The AIP was significantly higher in the SAP group compared to the non-SAP group (p < 0.001). The AIP was positively correlated with the Atlanta classification (R = 0.256, p < 0.001). In multivariate analysis, the AIP was found to be an independent predictive factor for SAP (OR = 4.571; CI = 1.913–10.922; p = 0.001). Conclusions: The AIP is a potential biomarker for the prediction of SAP in clinical practice. This result provides that impaired lipid metabolism is associated with the severity of pancreatitis.

Background: Early diagnosis of severe acute pancreatitis (AP) is important to reduce morbidity and mortality. We investigated the association between the triglyceride and glucose index (TyG index) and the prognosis of severe AP (SAP)., Methods: The TyG index was calculated as: ln [fasting triglycerides (mg/dL) x fasting plasma glucose (mg/dL)]/2. Multivariable logistic regression analyses were used to investigate the independent association between the TyG index and the severity of AP., Results: In this study, 373 patients with AP were recruited from three hospitals. The TyG index was higher in the SAP group than in the non-SAP group. Further, the TyG index was higher than in patients admitted to an intensive care unit and those who died of AP. The TyG index was an independent predictive factor for SAP (odds ratio 7.14, 95% confidence interval 2.80-18.19). The area under the curve increased significantly, from 0.738 to 0.830, after adding the TyG index to a predictive SAP model., Conclusions: Our findings suggest that the TyG index is an independent prognostic factor in patients with AP and could be used as a simple prognostic indicator for SAP., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2020 IAP and EPC.

Acute pancreatitis (AP) is a common disease that may involve pancreas and peripancreatic tissues with a prevalence of up to 50 per 100,000 individuals for year. The Atlanta classification was assessed for the first time in 1992 and modified in 2012 in order to describe morphological features of AP and its complications. AP can be morphologically distinguished in two main types: interstitial edematous pancreatitis (IEP) and necrotizing pancreatitis (NEP). This classification is very important because the presence of necrosis is directly linked to local or systemic complications, hospital stays and death. Magnetic resonance (MR) is very useful to characterize morphological features in AP and its abdominal complications. Particularly we would like to underline the diagnostic, staging and prognostic role of T1-weighted images with fat suppression that could be significant to assess many features of the AP inflammatory process and its complications (detection of the pancreatic contour, pancreatic necrosis, presence of haemorrhage). Signs of inflammatory and edema are instead observed by T1-weighted images. MR cholangiopancreatography (MRCP) is necessary to study the main pancreatic duct and the extrahepatic biliary tract and contrast-enhancement magnetic resonance imaging (MRI) allows to assess the extent of necrosis and vascular injuries., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/gs-20-554).

The ongoing pandemic of Coronavirus disease-2019 (COVID-19) has spread over 200 countries worldwide, affecting >2 million people and >120,000 deaths. COVID-19 is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The most common symptoms include cough, shortness of breath, and fever. However, gastrointestinal manifestations of COVID-19 are increasingly being recognized. Herein, we report a case of COVID-19 who presented with acute pancreatitis (AP) without any other risk factors., Competing Interests: Declaration of competing interest None., (Copyright © 2020 IAP and EPC.
