Abstract
Acute pancreatitis (AP) is a sudden-onset inflammatory disease of the pancreas. The severity of AP is classified into mild, moderate, and severe categories based on the presence and persistence of organ failure. Severe acute pancreatitis (SAP) can be associated with significant morbidity and mortality. It requires early recognition for appropriate timely management. Prognostic scores for predicting SAP incorporating many clinical, laboratory, and radiological parameters have been developed in the past. However, all of these prognostic scores have low positive predictive value for SAP and some of these scores require >24 h for assessment. There is a need to develop biomarkers that can accurately identify patients at risk for SAP early in the course of the presentation. In this review, we aim to provide a summary of the most commonly utilized prognostic scores for AP and discuss future directions.

Abstract
Background Severe acute pancreatitis (SAP) has a mortality rate as high as 40%. Early identification of SAP is required to appropriately triage and direct initial therapies. The purpose of this study was to develop a prognostic model that identifies patients at risk for developing SAP of patients managed according to a guideline-based standardized early medical management (EMM) protocol. Methods This single-center study included all patients diagnosed with acute pancreatitis (AP) and managed with the EMM protocol Methodist Acute Pancreatitis Protocol (MAPP) between April 2017 and September 2022. Classification and regression tree (CART®; Professional Extended Edition, version 8.0; Salford Systems, San Diego, CA), univariate, and logistic regression analyses were performed to develop a scoring system for AP severity prediction. The accuracy of the scoring system was measured by the area under the receiver operating characteristic curve. Results A total of 516 patients with mild (n=436) or moderately severe and severe (n=80) AP were analyzed. CART analysis identified the cutoff values: creatinine (CR) (1.15 mg/dL), white blood cells (WBC) (10.5 × 109/L), procalcitonin (PCT) (0.155 ng/mL), and systemic inflammatory response system (SIRS). The prediction model was built with a multivariable logistic regression analysis, which identified CR, WBC, PCT, and SIRS as the main predictors of severity. When CR and only one other predictor value (WBC, PCT, or SIRS) met thresholds, then the probability of predicting SAP was >30%. The probability of predicting SAP was 72% (95%CI: 0.59-0.82) if all four of the main predictors were greater than the cutoff values. Conclusions Baseline laboratory cutoff values were identified and a logistic regression-based prognostic model was developed to identify patients treated with a standardized EMM who were at risk for SAP.

Abstract
BACKGROUND Acute pancreatitis (AP) with critical illness is linked to increased morbidity and mortality. Current risk scores to identify high-risk AP patients have certain limitations. OBJECTIVE To develop and validate a machine learning tool within 48 h after admission for predicting which patients with AP will develop critical illness based on ubiquitously available clinical, laboratory, and radiologic variables. METHODS 5460 AP patients were enrolled. Clinical, laboratory, and imaging variables were collected within 48 h after hospital admission. Least Absolute Shrinkage Selection Operator with bootstrap method was employed to select the most informative variables. Five different machine learning models were constructed to predictive likelihood of critical illness, and the optimal model (APCU) was selected. External cohort was used to validate APCU. APCU and other risk scores were compared using multivariate analysis. Models were evaluated by area under the curve (AUC). The decision curve analysis was employed to evaluate the standardized net benefit. RESULTS Xgboost was constructed and selected as APCU, involving age, comorbid disease, mental status, pulmonary infiltrates, procalcitonin (PCT), neutrophil percentage (Neu%), ALT/AST, ratio of albumin and globulin, cholinesterase, Urea, Glu, AST and serum total cholesterol. The APCU performed excellently in discriminating AP risk in internal cohort (AUC = 0.95) and external cohort (AUC = 0.873). The APCU was significant for biliogenic AP (OR = 4.25 [2.08-8.72], P < 0.001), alcoholic AP (OR = 3.60 [1.67-7.72], P = 0.001), hyperlipidemic AP (OR = 2.63 [1.28-5.37], P = 0.008) and tumor AP (OR = 4.57 [2.14-9.72], P < 0.001). APCU yielded the highest clinical net benefit, comparatively. CONCLUSION Machine learning tool based on ubiquitously available clinical variables accurately predicts the development of AP, optimizing the management of AP.

Abstract
Acute pancreatitis has a diverse etiology and natural history, and some patients have severe complications with a high risk of mortality. The prediction of the severity of acute pancreatitis should be achieved by a careful ongoing clinical assessment coupled with the use of a multiple-factor scoring system and imaging studies. Over the past 40 years, various scoring systems have been suggested to predict the severity of acute pancreatitis. However, there is no definite and ideal scoring system with a high sensitivity and specificity. The interest in new biological markers and predictive models for identifying severe acute pancreatitis testifies to the continued clinical importance of early severity prediction. Although contrast-enhanced computed tomography (CT) is considered the gold standard for diagnosing pancreatic necrosis, early scanning for the prediction of severity is limited because the full extent of pancreatic necrosis may not develop within the first 48 h of presentation. This article provides an overview of the available scoring systems and biochemical markers for predicting severe acute pancreatitis, with a focus on their characteristics and limitations.

Abstract
BACKGROUND Infection in acute pancreatitis will worsen the disease prognosis. The aim of our study was to analyze the role of procalcitonin as a prognostic biomarker for infections and clinical severity. METHOD A prospective single-cohort observational study of patients diagnosed of acute pancreatitis (n = 152) was designed. PCT determination was tested on admission (first 72 h). Infections (biliary, extrapancreatic and infected pancreatic necrosis), need for antibiotics, urgent ERCP and severity scores for acute pancreatitis was assessed. ROC curves were designed and the area under the curve was calculated. Logistic regression for multivariate analysis was performed to evaluate the association between procalcitonin optimal cut-off level and major complications. RESULTS PCT >0.68 mg/dL had higher incidence of global infection, acute cholangitis, bacteraemia, infected pancreatic necrosis, use of antibiotics in general, and need for urgent ERCP. In the multivariate regressions analysis, PCT >0.68 mg/dL at admission demonstrated to be a strong risk factor for complications in acute pancreatitis. DISCUSSION PCT levels can be used as a reliable laboratory test to predict infections and the clinical severity of acute pancreatitis. High levels of PCT predict antibiotics prescription as well as the need for urgent ERCP in patients with concomitant clinically severe cholangitis.

Abstract
Introduction: Acute pancreatitis (AP) is a common gastrointestinal disease with a wide spectrum of severity and morbidity. Developed in 1974, the Ranson score was the first scoring system to prognosticate AP. Over the past decades, while the Ranson score remains widely used, it was identified to have certain limitations, such as having low predictive power. It has also been criticized for its 48-hour requirement for computation of the final score, which has been argued to potentially delay management. With advancements in our understanding of AP, is the Ranson score still relevant as an effective prognostication system for AP?Areas covered: This review summarizes the available evidence comparing Ranson score with other conventional and novel scoring systems, in terms of prognostic accuracy, benefits, limitations and clinical applicability. It also evaluates the effectiveness of Ranson score with regard to the Revised Atlanta Classification.Expert opinion: The Ranson score consistently exhibits comparable prognostic accuracy to other newer scoring systems, and the 48-hour timeframe for computing the full Ranson score is an inherent strength, not a weakness. These aspects, coupled with relative ease of use, practicality and universality of the score, advocate for the continued relevance of the Ranson score in modern clinical practice.

Abstract
Background and study aims Endothelial cell specific molecule-1 (ESM-1), also known as endocan, is a soluble proteoglycan secreted by human vascular endothelial cells. In some studies, it has been found that endocan have important effects on cell adhesion, inflammation and angiogenesis. In this study, we aimed to evaluate the endocan level in patients with pancreatitis and the availability of endocan level in determining the severity of the disease. Patients and methods A total of 42 patients with pancreatitis and 33 healthy individuals were included in the study. The serum endocan levels in patients were evaluated 1st and 3 th days after the symptom's onset. Current scoring systems and the relationship between the severity of the disease and endocan levels were evaluated. Results The endocan levels of the patients on day 1 are significantly correlated only with the APACHE II score (p=0.039 r=0.319), while the endocan values on day 3 are significantly correlated with the BISAP (bedside index of severity in acute pancreatitis) (p=0.013 r=0.380), APACHE II (Acute Physiology and Chronic Health Evaluation)(p<0.001; r=0.53) and Ranson (p=0.037 r=0.32) scores. The cutoff level of endocan (day 3) was calculated 92.2 pg/ml (83% sensitivity and 50% specificity; p=0.039 area under the curve 0.706) for severe pancreatitis when considering the patients with a score of 8 or higher in the APACHE II scoring system. Conclusion Serum endocan level can be used as a marker of prognosis in patients with pancreatitis. However, studies involving large populations are needed on this matter.

Abstract
BACKGROUND The COVID-19 pandemic caused by SARS-CoV-2 commenced in Wuhan China in 2019 and soon spread worldwide. SARS-CoV-2 enters the cell by binding to the ACE II receptor and begins viral replication. The effects and clinical findings of SARS-CoV-2 on the liver, kidney, heart, gastrointestinal (GI) system and especially lungs have been widely discussed. However, the effects on the pancreas-another organ that also expresses ACE II-have not been studied. METHODS This work prospectively evaluated data from 316 patients who were admitted with a diagnosis of COVID-19 pneumonia. The patients were categorized into three according to the severity of pneumonia (mild, severe, critical). Demographic data, rate of pancreatitis, biochemical parameters, and radiological images from each group were analyzed. The patients were divided into two groups and outcomes were compared: COVID-19 patients with acute pancreatitis (Group P) and without acute pancreatitis (Group C). RESULTS The median age was 54 (18-87), and the median age for patients with acute pancreatitis was 55 (26-84). As an expected finding, we found a positive correlation between advanced age and mortality (p = 0.0003). 12.6% of the patients had acute pancreatitis. While pancreatitis was not seen in patients on mild status, the rate of pancreatitis was 32.5% in critical patients. Hospitalization and mortality rates were higher in patients with COVID-19 accompanied by acute pancreatitis (p = 0.0038 and p < 0.0001, respectively). C-Reactive Protein (CRP) and ferritin were significantly higher in those who had pancreatitis (p < 0.0001). D-Dimer and procalcitonin levels had only a small difference (p = 0.1127 and p = 0.3403, respectively). CONCLUSION Acute pancreatitis alone is a clinical condition that can lead to mortality and may be one of the reasons for the exaggerated immune response developing in the progression of COVID-19. Our results point out that the presence of pancreatic damage triggered by SARS-CoV-2 can deteriorate the clinical condition of patients and the mortality rate may increase in these patients.

Abstract
Acute pancreatitis (AP) is an inflammatory disorder of the pancreas that, when classified as severe, is associated with high morbidity and mortality. Promptly identifying the severity of AP is of extreme importance for improving clinical outcomes. The aim of this study was to compare the prognostic value of serological biomarkers, ratios, and multifactorial scores in patients with acute biliary pancreatitis and to identify the best predictors. In this observational and prospective study, the biomarkers, ratios and multifactorial scores were evaluated on admission and at 48 h of the symptom onset. On admission, regarding the AP severity, the white blood count (WBC) and neutrophil-lymphocyte ratio (NLR), and regarding the mortality, the WBC and the modified Marshall score (MMS) showed the best predictive values. At 48 h, regarding the AP severity, the hepcidin, NLR, systemic inflammatory response index (SIRI) and MMS and regarding the mortality, the NLR, hepcidin and the bedside index for severity in AP (BISAP) score, showed the best predictive values. The present study enabled the identification, for the first time, of SIRI as a new prognostic tool for AP severity, and validated hepcidin and the NLR as better prognostic markers than C-reactive protein (CRP) at 48 h of symptom onset.

Abstract
BACKGROUND Acute pancreatitis is a common disease, the incidence of which is 75-100/100,000/year in Finland. The worldwide incidence of acute pancreatitis is increasing. The identified mildcases usually show rapid recovery with conservative treatment allowing early discharge. Severe cases need early intensive care to reduce the risk of serious complications such as multi-organ failure. The revised Atlanta classification of acute pancreatitis was introduced in 2012-2013. A recurrent acute pancreatitis is defined as two or more well-documented separate attacks of acute pancreatitis with complete resolution in between. Alcoholic pancreatitis is the most common recurrent acute pancreatitis type. METHODS In this review current severity classifications and literature on the prevention of recurrent acute pancreatitis are analyzed. RESULTS The severity of the disease is classified as mild, moderately severe, and severe acute pancreatitis. Novel entities include acute peripancreatic fluid collections in mild acute pancreatitis and acute necrotic collections in necrotizing acute pancreatitis lesser than 4 weeks after the onset and pancreatic pseudocyst in mild acute pancreatitis and walled-off necrosis in necrotizing acute pancreatitis more than 4 weeks after the onset of the disease. After the first attack of alcohol-induced acute pancreatitis, 46% of the patients develop at least one recurrence within 10- to 20-year follow-up. With repeated intervention against alcohol consumption, it is possible to reduce the recurrences. Removing the gall bladder after biliary pancreatitis is the key preventing recurrences. In mild cases, even during the index admission; in severe cases, it is recommended to wait until the inflammatory changes have resolved. Of total, 59% of the idiopathic pancreatitis had sludge of stones in the gall bladder. In other etiologies, addressing the etiological factor may prevent recurrent acute pancreatitis. CONCLUSIONS This review describes current use of novel severity classifications and also different possibilities to prevent recurrent acute pancreatitis with different etiologies including idiopathic.

Abstract
Early diagnosis of sepsis is often difficult in clinical practice, whilst it can be vital for positive patient outcomes in sepsis management. Any delay in diagnosis and treatment may lead to significant organ failure and can be associated with elevated mortality rates. Early diagnosis and effective management of sepsis can allow for prompt antibiotic therapy and a potential reduction in mortality; it can also minimize the unnecessary use of antibiotics. Furthermore, vitamin D supplementation, which is commonly used in the intensive care units to reduce mortality, may interfere with the ability to use procalcitonin (PCT) as a means of assessing clinical progression. This paper aims to explore the diagnostic and prognostic value of serum levels of PCT as an early marker of sepsis and to assess whether it can be used as a guide for using antibiotic therapy. Several serum-based biomarkers such as C-reactive protein, lactate, presepsin, and cytokines, such as interleukin-1 (IL-1), and IL-6 have been evaluated as early indicators of sepsis but none have been proven sensitive and/or specific enough to make a definitive diagnosis. Finally the potential benefits and disadvantages of using serum levels of PCT to diagnose and monitor patients with sepsis and septic shock will be briefly discussed.

Abstract
INTRODUCTION Severe acute pancreatitis has a high mortality and its early identification is important for management and risk stratification. The bedside index for severity in acute pancreatitis (BISAP) is a simple scoring system done at admission which predicts the severity of pancreatitis. Procalcitonin is an inflammatory marker which is raised very early and helps in early prediction of the severity of disease. This study aims to evaluate the BISAP score and Procalcitonin in prognostication of acute pancreatitis. METHODS A prospective observational study of 60 patients presenting with acute pancreatitis was done at XXX Medical College and Hospital from July 2015 to June 2016. BISAP, APACHE-II, Ranson criteria, and CT severity index (CTSI) of all patients were calculated. Procalcitonin card test was done for all patients. The patients were stratified according by BISAP score and procalcitonin positivity into categories of severe pancreatitis, organ failure and pancreatic necrosis, as well as the number of deaths. The comparison of BISAP with other scoring systems, Procalcitonin (PCT), C-reactive protein (CRP), hematocrit, and body mass index (BMI) was done by the area under the receiver-operating curve (AUC) to prediction of severe acute pancreatitis, organ failure, necrosis, and death. RESULTS Of the 60 patients, 14 (23.3%) developed severe acute pancreatitis, 11 (18.3%) Organ failure, 21 (35%) pancreatic necrosis and 7 (11.6%) died. A BISAP score of ≥3 was a statistically significant cutoff value. AUCs for predicting severe pancreatitis and death of BISAP were 0.875 and 0.740respectively, similar to those for Ranson criteria (0.802, 0.763) and APACHE-II (0.891, 0.769) and greater than AUCs for CTSI (0.641, 0.554). The AUC for prediction of organ failure were 0.906, 0.833, 0.874 and 0.623 for BISAP, Ranson criteria, APACHE-II, and CTSI respectively. AUCs for PCT predicting severity, organ failure, and death were 0.940, 0.923 and 0.769 respectively were similar to BISAP but greater than those for CRP (0.755, 0.719, 0.693), hematocrit (0.540, 0.570, 0.550), and BMI (0.493, 0.523, 0.497). CONCLUSION The BISAP predicts severity, organ failure and death, in acute pancreatitis very well.It is as good as APACHE-II but better than Ranson criteria, CTSI, CRP, hematocrit, and BMI. PCT is a promising inflammatory marker with prediction rates similar to BISAP.

Abstract
OBJECTIVES This pilot study aimed to determine the feasibility of serum values of osteonectin, adiponectin, transforming growth factor beta 1, and neurotensin being used in clinical practice to predict the severity of acute pancreatitis. METHODS Blood samples were collected from 45 consecutive newly diagnosed acute pancreatitis patients and 30 matched healthy controls. The 2 groups were matched according to age, sex, weight, height, diabetes, smoking, and alcohol consumption. The aforementioned markers were measured using enzyme-linked immunosorbent assay kits. RESULTS Characteristics of acute pancreatitis patients and healthy controls were comparable. Osteonectin values differed significantly (P < 0.0001). Median/lower quartile/upper quartile of osteonectin levels for acute pancreatitis patients and healthy controls were 263.5/110.3/490.36 and 63.2/46.1/87.2 ng/mL, respectively. Two patients died, 1 patient underwent necrosectomy, and 4 patients had a prolonged intensive care unit/hospital stay. Acute Physiology and Chronic Health Evaluation II and Systemic Inflammatory Response Syndrome scores neither predicted serum values of any of the measured substances nor the clinical outcome (need for intervention, prolonged intensive care unit/hospital stay and mortality). Osteonectin was the only independent predictor for clinical outcome (P = 0.007). CONCLUSIONS Serum osteonectin strongly discriminates healthy individuals from acute pancreatitis patients. Serum osteonectin shows promise in the prediction of the clinical outcome.

Abstract
The last two decades have seen the emergence of significant evidence that has altered certain aspects of the management of acute pancreatitis. While most cases of acute pancreatitis are mild, the challenge remains in managing the severe cases and the complications associated with acute pancreatitis. Gallstones are still the most common cause with epidemiological trends indicating a rising incidence. The surgical management of acute gallstone pancreatitis has evolved. In this article, we revisit and review the methods in diagnosing acute pancreatitis. We present the evidence for the supportive management of the condition, and then discuss the management of acute gallstone pancreatitis. Based on the evidence, our local institutional pathways, and clinical experience, we have produced an outline to guide clinicians in the management of acute gallstone pancreatitis.

Abstract
Timely recognition of systemic bacterial infections in pediatric care setting is the basis for effective treatment and control. This review provides an overview of procalcitonin (PCT) as an early marker for the detection of severe, invasive bacterial infection in children. Almost all articles on biochemical property and clinical studies in PubMed and Scopus databases regarding their use in pediatric infections and the use of PCT as a marker of bacterial infections were examined. Various methods and analyzers are currently available for the evaluation of PCT. Employment of PCT in the identification of neonatal bacterial infection is a complex process in some conditions. Age specific cut-off, underlying syndrome, and maternal antibiotics usage should be considered when PCT is to be applied in neonates. PCT might be false-negative in these conditions. However, if used appropriately, it can lead to a higher specificity than other immunologic markers. Due to its correlation with the severity of infection, PCT can consequently be used as a prognostic indicator especially for sepsis and urinary tract infection. It is, therefore, a practical supplementary means for the identification of bacterial infections in pediatric health settings.

Abstract
BACKGROUND The treatment of people with pancreatic necrosis differs from that of people with oedematous pancreatitis. It is important to know the diagnostic accuracy of serum C-reactive protein (CRP), serum procalcitonin, and serum lactate dehydrogenase (LDH) as a triage test for the detection of pancreatic necrosis in people with acute pancreatitis, so that an informed decision can be made as to whether the person with pancreatic necrosis needs further investigations such as computed tomography (CT) scan or magnetic resonance imaging (MRI) scan and treatment for pancreatic necrosis started. There is currently no standard clinical practice, although CRP, particularly an increasing trend of CRP, is often used as a triage test to determine whether the person requires further imaging. There is also currently no systematic review of the diagnostic test accuracy of CRP, procalcitonin, and LDH for the diagnosis of pancreatic necrosis in people with acute pancreatitis. OBJECTIVES To compare the diagnostic accuracy of CRP, procalcitonin, or LDH (index test), either alone or in combination, in the diagnosis of necrotising pancreatitis in people with acute pancreatitis and without organ failure. SEARCH METHODS We searched MEDLINE, Embase, Science Citation Index Expanded, National Institute for Health Research (NIHR HTA and DARE), and other databases until March 2017. We searched the references of the included studies to identify additional studies. We did not restrict studies based on language or publication status, or whether data were collected prospectively or retrospectively. We also performed a 'related search' and 'citing reference' search in MEDLINE and Embase. SELECTION CRITERIA We included all studies that evaluated the diagnostic test accuracy of CRP, procalcitonin, and LDH for the diagnosis of pancreatic necrosis in people with acute pancreatitis using the following reference standards, either alone or in combination: radiological features of pancreatic necrosis (contrast-enhanced CT or MRI), surgeon's judgement of pancreatic necrosis during surgery, or histological confirmation of pancreatic necrosis. Had we found case-control studies, we planned to exclude them because they are prone to bias; however, we did not locate any. Two review authors independently identified the relevant studies from the retrieved references. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data, including methodological quality assessment, from the included studies. As the included studies reported CRP, procalcitonin, and LDH on different days of admission and measured at different cut-off levels, it was not possible to perform a meta-analysis using the bivariate model as planned. We have reported the sensitivity, specificity, post-test probability of a positive and negative index test along with 95% confidence interval (CI) on each of the different days of admission and measured at different cut-off levels. MAIN RESULTS A total of three studies including 242 participants met the inclusion criteria for this review. One study reported the diagnostic performance of CRP for two threshold levels (> 200 mg/L and > 279 mg/L) without stating the day on which the CRP was measured. One study reported the diagnostic performance of procalcitonin on day 1 (1 day after admission) using a threshold level of 0.5 ng/mL. One study reported the diagnostic performance of CRP on day 3 (3 days after admission) using a threshold level of 140 mg/L and LDH on day 5 (5 days after admission) using a threshold level of 290 U/L. The sensitivities and specificities varied: the point estimate of the sensitivities ranged from 0.72 to 0.88, while the point estimate of the specificities ranged from 0.75 to 1.00 for the different index tests on different days of hospital admission. However, the confidence intervals were wide: confidence intervals of sensitivities ranged from 0.51 to 0.97, while those of specificities ranged from 0.18 to 1.00 for the different tests on different days of hospital admission. Overall, none of the tests assessed in this review were sufficiently accurate to suggest that they could be useful in clinical practice. AUTHORS' CONCLUSIONS The paucity of data and methodological deficiencies in the studies meant that it was not possible to arrive at any conclusions regarding the diagnostic test accuracy of the index test because of the uncertainty of the results. Further well-designed diagnostic test accuracy studies with prespecified index test thresholds of CRP, procalcitonin, LDH; appropriate follow-up (for at least two weeks to ensure that the person does not have pancreatic necrosis, as early scans may not indicate pancreatic necrosis); and clearly defined reference standards (of surgical or radiological confirmation of pancreatic necrosis) are important to reliably determine the diagnostic accuracy of CRP, procalcitonin, and LDH.

Abstract
Acute pancreatitis is a common digestive disease of which the severity may vary from mild, edematous to severe, necrotizing disease. An improved outcome in the severe form of the disease is based on early identification of disease severity and subsequent focused management of these high-risk patients. However, the ability of clinicians to predict, upon presentation, which patient will have mild or severe acute pancreatitis is not accurate. Prospective systems using clinical criteria have been used to determine severity in patients with acute pancreatitis, such as the Ranson's prognostic signs, Glasgow score, and the acute physiology and chronic health evaluation II score (APACHE II). Their application in clinical practise has been limited by the time delay of at least 48 h to judge all parameters in the former two and by being cumbersome and time-consuming in the latter. Contrast-enhanced computed tomography is presently the most accurate non-invasive single method to evaluate the severity of acute pancreatitis. It cannot, however, be performed to all patients with acute pancreatitis. Therefore, considerable interest has grown in the development of reliable biochemical markers that reflect the severity of acute pancreatitis. In this article we critically appraise current and new severity markers of acute pancreatitis in their ability to distinguish between mild and severe disease and their clinical utility.

Abstract
Infection is a life-threatening complication after liver transplantation (LT). A recent outbreak of multidrug-resistant Pseudomonas aeruginosa triggered changes in our infection control measures. This study investigated the usefulness of our bundled interventions against postoperative infection after LT. This before-and-after analysis enrolled 130 patients who underwent living donor or deceased donor LT between January 2011 and October 2014. We initiated 3 measures after January 2013: (1) we required LT candidates to be able to walk independently; (2) we increased the hand hygiene compliance rate and contact precautions; and (3) we introduced procalcitonin (PCT) measurement for a more precise determination of empirical antimicrobial treatment. We compared factors affecting the emergence of drug-resistant microorganisms, such as the duration of antimicrobial and carbapenem therapy and hospital stay, and outcomes such as bacteremia and death from infection between before (n = 77) and after (n = 53) the LT suspension period. The utility of PCT measurement was also evaluated. Patients' backgrounds were not significantly different before and after the protocol revision. Incidence of bacteremia (44% versus 25%; P = 0.02), detection rate of multiple bacteria (18% versus 4%; P = 0.01), and deaths from infections (12% versus 2%; P = 0.04) significantly decreased after the protocol revision. Duration of antibiotic (42.3 versus 25.1 days; P = 0.002) and carbapenem administration (15.1 versus 5.2 days; P < 0.001) and the length of postoperative hospital stay (85.4 versus 63.5 days; P = 0.048) also decreased after the protocol revision. PCT mean values were significantly higher in the bacteremia group (10.10 ng/mL), compared with the uneventful group (0.65 ng/mL; P = 0.002) and rejection group (2.30 ng/mL; P = 0.02). One-year overall survival after LT significantly increased in the latter period (71% versus 94%; P = 0.001). In conclusion, the bundled interventions were useful in preventing infections and lengthening overall survival after LT.

Abstract
BACKGROUND Necrotizing pancreatitis is a challenging condition that requires surgical treatment commonly and is associated with substantial morbidity and mortality. Over the past decade, new definitions have been developed for standardization of severity of acute and necrotizing pancreatitis, and new management techniques have emerged based on prospective, randomized clinical trials. METHODS Review of English-language literature. RESULTS A new international classification of acute pancreatitis has been developed by PANCREA (Pancreatitis Across Nations Clinical Research and Education Alliance) to replace the Atlanta Classification. It is based on the actual local (whether pancreatic necrosis is present or not, whether it is sterile or infected) and systemic determinants (whether organ failure is present or not, whether it is transient or persistent) of severity. Early management requires goal-directed fluid resuscitation (with avoidance of over-resuscitation and abdominal compartment syndrome), assessment of severity of pancreatitis, diagnostic computed tomography (CT) imaging to assess for necrotizing pancreatitis, consideration of endoscopic retrograde cholangiopancreatography (ERCP) for biliary pancreatitis and early enteral nutrition support. Antibiotic prophylaxis is not recommended. Therapeutic antibiotics are required for treatment of documented infected pancreatic necrosis. The initial treatment of infected pancreatic necrosis is percutaneous catheter or endoscopic (transgastric/transduodenal) drainage with a second drain placement as required. Lack of clinical improvement after these initial procedures warrants consideration of minimally invasive techniques for pancreatic necrosectomy including video-assisted retroperitoneal debridement (VARD), minimally invasive retroperitoneal pancreatectomy (MIRP), or transluminal direct endoscopic necrosectomy (DEN). Open necrosectomy is associated with substantial morbidity, but to date no randomized trial has documented superiority of either minimally invasive or open surgical technique. Additional trials are underway to address this. CONCLUSIONS Severe acute and necrotizing pancreatitis requires a multi-disciplinary treatment strategy that must be individualized for each patient. Optimal treatment of necrotizing pancreatitis now requires a staged, multi-disciplinary, minimally invasive "step-up" approach that includes a team of interventional radiologists, therapeutic endoscopists, and surgeons.

Abstract
OBJECTIVE The aim of this study was to investigate the influence of the greater splanchnic nerve (GSN) transection on the pathophysiological process of acute necrotizing pancreatitis (ANP). METHODS The dogs were divided into a sham operation (SO) group, ANP group, and ANP with bilateral GSN transection (GSNT) group. Dogs in the GSNT group underwent bilateral GSNT immediately after ANP induction. The levels of serum pancreatic amylase (AMY), calcium, high-sensitivity C-reactive protein (HCRP), tumor necrosis factor α (TNF-α), interleukin 10 (IL-10), and neutrophile granulocyte (NEU) counts were monitored dynamically, and the pathological examinations of the pancreas was performed at postoperative day 7. RESULTS All the parameters among the 3 groups showed no differences before the experiment (P > 0.05). At different postoperative times, the NEU count and serum AMY, TNF-α, HCRP, and IL-10 were significantly increased; however, the serum calcium had decreased in the ANP group versus SO (P < 0.05). The postoperative serum IL-10 and calcium levels were higher, and TNF-α, HCRP, and NEU counts were lower in the GSNT group compared with those in the ANP group (P < 0.05); as for AMY, no significant difference was found between the 2 groups (P > 0.05). The pancreas pathological scoring of the GSNT group was lower versus the ANP group (P < 0.05). CONCLUSIONS Greater splanchnic nerve transection can alleviate development of pathophysiological processes in ANP.

Abstract
Acute pancreatitis is a potentially life threatening disease. The spectrum of severity of the illness ranges from mild self-limiting disease to a highly fatal severe necrotizing pancreatitis. Despite intensive research and improved patient care, overall mortality still remains high, reaching up to 30–40% in cases with infected pancreatic necrosis. Although little is known about the exact pathogenesis, it has been widely accepted that premature activation of digestive enzymes within the pancreatic acinar cell is the trigger that leads to autodigestion of pancreatic tissue which is followed by infiltration and activation of leukocytes. Extensive research has been done over the past few decades regarding their role in diagnosis and prognostic evaluation of severe acute pancreatitis. Although many standalone biochemical markers have been studied for early assessment of severity, C-reactive protein still remains the most frequently used along with Interleukin-6. In this review we have discussed briefly the pathogenesis and the role of different biochemical markers in the diagnosis and severity evaluation in acute pancreatitis.

Ferreira ADF, Bartelega JA, Urbano HCDA, de Souza IKF. Acute pancreatitis gravity predictive factors: which and when to use them? ARQUIVOS BRASILEIROS DE CIRURGIA DIGESTIVA : ABCD = BRAZILIAN ARCHIVES OF DIGESTIVE SURGERY 2015; 28:207-11.

Abstract
INTRODUCTION Acute pancreatitis has as its main causes lithiasic biliary disease and alcohol abuse. Most of the time, the disease shows a self-limiting course, with a rapid recovery, only with supportive treatment. However, in a significant percentage of cases, it runs with important local and systemic complications associated with high mortality rates. AIM To present the current state of the use of these prognostic factors (predictive scores) of gravity, as the time of application, complexity and specificity. METHOD A non-systematic literature review through 28 papers, with emphasis on 13 articles published in indexed journals between 2008 and 2013 using Lilacs, Medline, Pubmed. RESULTS Several clinical, laboratory analysis, molecular and image variables can predict the development of severe acute pancreatitis. Some of them by themselves can be determinant to the progression of the disease to a more severe form, such as obesity, hematocrit, age and smoking. Hematocrit with a value lower than 44% and serum urea lower than 20 mg/dl, both at admission, appear as risk factors for pancreatic necrosis. But the PCR differentiates mild cases of serious ones in the first 24 h. Multifactorial scores measured on admission and during the first 48 h of hospitalization have been used in intensive care units, being the most ones used: Ranson, Apache II, Glasgow, Iget and Saps II. CONCLUSION Acute pancreatitis is a disease in which several prognostic factors are employed being useful in predicting mortality and on the development of the severe form. It is suggested that the association of a multifactorial score, especially the Saps II associated with Iget, may increase the prognosis accuracy. However, the professional's preferences, the experience on the service as well as the available tools, are factors that have determined the choice of the most suitable predictive score.

Abstract
BACKGROUND The nervous system interacts dynamically with the immune system to modulate inflammation through humoral and neural pathways. However, the influence of visceral nerve (VN) on acute necrotizing pancreatitis (ANP) has drawn little attention. AIM To investigate the influence of VN on the pathophysiological process of ANP in dogs. METHODS The dogs were divided into a sham operation (SO) group, ANP group, ANP + vagal nerve trunk transection (VNTT) group, and ANP + greater splanchnic nerve transection (GSNT) group. The VNTT and GSNT groups underwent VNTT and GSNT respectively immediately after ANP induction. The levels of serum pancreatic amylase (AMY), calcium, high-sensitivity C-reactive protein (HCRP), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-10 (IL-10) were monitored dynamically and the pathological examinations of the pancreas was performed at postoperative day 7. RESULTS All serum parameters among the four groups showed no differences before the experiment (p > 0.05). At different postoperative times, the serum TNF-α, IL-1β, HCRP, and AMY were significantly increased, however, the serum calcium and IL-10 had dropped in the ANP group versus SO group (p < 0.05); an alike variation trend occurred between the VNTT group and ANP group (p < 0.05); an opposite variation trend occurred between the GSNT group and the ANP group (p < 0.05). The pancreas pathological scoring of VNTT group was highest in the four groups (p < 0.05) and GSNT group was lower versus ANP group (p < 0.05). CONCLUSIONS The GSNT has been shown to alleviate development of ANP, however, VNTT may exacerbate the ANP.

Abstract
Procalcitonin (PCT) is used as a biomarker for the diagnosis of sepsis, severe sepsis and septic shock. At the same time, PCT has also been used to guide antibiotic therapy. This review outlines the main indications for PCT measurement and points out possible pitfalls. The classic indications for PCT measurement are: (i) confirmation or exclusion of diagnosis of sepsis, severe sepsis, or septic shock, (ii) severity assessment and follow up of systemic inflammation mainly induced by microbial infection, and (iii) individual, patient adapted guide of antibiotic therapy and focus treatment. Using serially monitored PCT levels, the duration and need of antibiotic therapy can be better adapted to the individual requirements of the patient. This individualized approach has been evaluated in various studies, and it is recommended to be a part of an antibiotic stewardship program.

Abstract
Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infection and sepsis. Studies have demonstrated its role in the setting of sepsis and acute pancreatitis. This study aims to analyze and compare the prognostic efficacy of plasma procalcitonin strip test in acute pancreatitis. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma procalcitonin was estimated by the semiquantitative strip test. The study included a total of 50 patients diagnosed to have acute pancreatitis. Data was collected and statistically analyzed using SPSS version 17. Thirty-nine out of the 50 patients (78 %) were males with a mean age of 46.8 years (range, 25-78 years) and 25 patients (50 %) had ethanol-induced pancreatitis, while 13 patients (26 %) had gall stone pancreatitis. Plasma PCT values were found to correlate better than CRP levels and total leukocyte count with the total duration of hospitalization, ITU, and ICU stay, as well as with the progression to severe acute pancreatitis. A cut off for plasma PCT of >2 ng/mL was found to be 100 % sensitive and 100 % specific and a cut off for CRP of >19 mg/dL was 70 % sensitive and 65 % specific for predicting the progression to severe acute pancreatitis. Plasma PCT also correlated well with antibiotic requirement. A cut off value of >0.5 ng/mL for plasma PCT was 100 % sensitive and 80 % specific and a cut off value of >18 mg/dL for CRP was 86 % sensitive and 63 % specific for predicting antibiotic requirement. Plasma procalcitonin is an early and reliable prognostic indicator in acute pancreatitis. The procalcitonin strip test is a rapid test which is useful in analyzing prognosis in patients with acute pancreatitis.

Abstract
Acute pancreatitis has a mortality rate of 5-10%. Early deaths are mainly due to multiorgan failure and late deaths are due to septic complications from pancreatic necrosis. The recently described 2012 Revised Atlanta Classification and the Determinant Classification both provide a more accurate description of edematous and necrotizing pancreatitis and local complications. The 2012 Revised Atlanta Classification uses the modified Marshall scoring system for assessing organ dysfunction. The Determinant Classification uses the sepsis-related organ failure assessment scoring system for organ dysfunction and, unlike the 2012 Revised Atlanta Classification, includes infected necrosis as a criterion of severity. These scoring systems are used to assess systemic complications requiring intensive therapy unit support and intra-abdominal complications requiring minimally invasive interventions. Numerous prognostic systems and markers have been evaluated but only the Glasgow system and serum CRP levels provide pragmatic prognostic accuracy early on. Novel concepts using genetic, transcriptomic and proteomic profiling and also functional imaging for the identification of specific disease patterns are now required.

Abstract
Background. Multifactorial scorings, radiological scores, and biochemical markers may help in early prediction of severity, pancreatic necrosis, and mortality in patients with acute pancreatitis (AP).
Methods. BISAP, APACHE-II, MOSS, and SIRS scores were calculated using data within 24 hrs of admission, whereas Ranson and Glasgow scores after 48 hrs of admission; CTSI was calculated on day 4 whereas IL-6 and CRP values at end of study. Predictive accuracy of scoring systems, sensitivity, specificity, and positive and negative predictive values of various markers in prediction of severe acute pancreatitis, organ failure, pancreatic necrosis, admission to intensive care units and mortality were calculated. Results. Of 72 patients, 31 patients had organ failure and local complication classified as severe acute pancreatitis, 17 had pancreatic necrosis, and 9 died (12.5%). Area under curves for Ranson, Glasgow, MOSS, SIRS, APACHE-II, BISAP, CTSI, IL-6, and CRP in predicting SAP were 0.85, 0.75, 0.73, 0.73, 0.88, 0.80, 0.90, and 0.91, respectively, for pancreatic necrosis 0.70, 0.64, 0.61, 0.61, 0.68, 0.61, 0.75, 0.86, and 0.90, respectively, and for mortality 0.84, 0.83, 0.77, 0.76, 0.86, 0.83, 0.57, 0.80, and 0.75, respectively. Conclusion. CRP and IL-6 have shown a promising result in early detection of severity and pancreatic necrosis whereas APACHE-II and Ranson score in predicting AP related mortality in this study.

Abstract
BACKGROUND Acute pancreatitis remains as one of the most difficult and challenging digestive disorder to predict in terms of clinical course and outcome. Every case has an individual course and therefore acute pancreatitis remains challenging and fascinating. Due to this variability, many different scoring systems have evolved during the last decades. Every scoring system has advantages and disadvantages. Not every scoring system is capable of assessing the clinical time course of the disease, some are only suitable for the time of initial presentation. AIM This paper will give an overview on the development of different widely used scoring systems and their performance in assessing severity and prognosis of acute pancreatitis. CONCLUSION Severity assessment means objective quantification of overall severity of illness. Early and reliable stratification of severity is required to decide best treatment of the individual patient, preparation for possible evolving complications or for referral to specialist centers. No single scoring system is able to cover the entire range of problems associated with treatment and assessment of acute pancreatitis. In our clinical experience, we recommend hematocrit upon admission, daily sequential organ failure assessment score and procalcitonin, C-reactive protein on day 3 and CT severity index beyond the first week. These scoring tools together with close clinical follow-up of the patient ultimately lead to an optimized treatment of this challenging disease.

Abstract
BACKGROUND/AIMS The bedside index of severity in acute pancreatitis (BISAP) is a new, convenient, prognostic multifactorial scoring system. As more data are needed before clinical application, we compared BISAP, the serum procalcitonin (PCT), and other multifactorial scoring systems simultaneously. METHODS Fifty consecutive acute pancreatitis patients were enrolled prospectively. Blood samples were obtained at admission and after 48 hours and imaging studies were performed within 48 hours of admission. The BISAP score was compared with the serum PCT, Ranson's score, and the acute physiology and chronic health examination (APACHE)-II, Glasgow, and Balthazar computed tomography severity index (BCTSI) scores. Acute pancreatitis was graded using the Atlanta criteria. The predictive accuracy of the scoring systems was measured using the area under the receiver-operating curve (AUC). RESULTS The accuracy of BISAP (≥ 2) at predicting severe acute pancreatitis was 84% and was superior to the serum PCT (≥ 3.29 ng/mL, 76%) which was similar to the APACHE-II score. The best cutoff value of BISAP was 2 (AUC, 0.873; 95% confidence interval, 0.770 to 0.976; p < 0.001). In logistic regression analysis, BISAP had greater statistical significance than serum PCT. CONCLUSIONS BISAP is more accurate for predicting the severity of acute pancreatitis than the serum PCT, APACHE-II, Glasgow, and BCTSI scores.

Abstract
Acute pancreatitis (AP) continues to be a clinical challenge. The mortality of patients with AP with adverse outcomes like organ failure and infected necrosis can be as high as 43 %. Highly accurate predictors of adverse outcomes are necessary to identify the high-risk patients so that they can be meticulously monitored and managed. However, there are no ideal predictors till date. Over the past several years, a number of single- and multi-parameter predictors have been identified and tested for prediction of adverse outcomes in AP. Out of the different tools tested, blood urea nitrogen and the harmless acute pancreatitis score appears to be useful and feasible in the management of AP under Indian conditions. Other single-parameter predictors like serum creatinine, hematocrit, erythrocyte sedimentation rate, C-reactive protein, and D-dimer need to be put to further tests in high-quality prospective studies with large sample size at the community level. Multi-parameter prediction tools like the bedside index of severity of acute pancreatitis may not be appealing in day-to-day clinical practice.

Abstract
Objective To determine if B cell activating factor of the tumor necrosis factor family (BAFF) acts as an acute phase reactant and predicts severity of acute pancreatitis. Methods 40 patients with acute pancreatitis were included in this single center cohort pilot study. Whole blood and serum was analyzed on day of admission and nine consecutive days for BAFF, c-reactive protein (CRP), interleukin-6 (IL-6), procalcitonin (PCT), and leucocyte numbers. Different severity Scores (Ranson, APACHE II, SAPS II, SAPS III) and the clinical course of the patient (treatment, duration of stay, duration ICU) were recorded. Results Serum BAFF correlates with CRP, an established marker of severity in acute pancreatitis at day of admission with a timecourse profil similar to IL-6 over the first nine days. Serum BAFF increases with Ranson score (Kruskal-Wallis: Chi2 = 10.8; p = 0.03) similar to CRP (Kruskal-Wallis: Chi2 = 9.4; p = 0.05 ). Serum BAFF, IL-6, and CRP levels are elevated in patients that need intensive care for more than seven days and in patients with complicated necrotizing pancreatitis. Discriminant analysis and receiver operator characteristics show that CRP (wilks-lambda = 0.549; ROC: AUC 0.948) and BAFF (wilks-lambda = 0.907; ROC: AUC 0.843) serum levels at day of admission best predict severe necrotizing pancreatitis or death, outperforming IL-6, PCT, and number of leucocytes. Conclusion This study establishes for the first time BAFF as an acute phase reactant with predictive value for the course of acute pancreatitis. BAFF outperforms established markers in acute pancreatitis, like IL-6 and PCT underscoring the important role of BAFF in the acute inflammatory response.

Abstract
BACKGROUND/AIMS Early assessment of disease severity and vigilant patient monitoring are key factors for adequate treatment of acute pancreatitis (AP). The aim of this study was to determine the correlation of procalcitonin (PCT) serum concentrations and intra-abdominal pressure (IAP) as prognostic markers in early stages of AP. METHODS This prospective observational study included 51 patients, of which 29 had severe AP (SAP). Patients were evaluated with the Acute Physiology And Chronic Health Evaluation (APACHE II) score, C-reactive protein (CRP) and PCT serum concentrations and IAP at 24 h from admission. PCT was measured three times in the 1st week of disease and three times afterward, while IAP was measured daily. PCT and IAP values correlated with each other, and also compared with APACHE II score and CRP values. RESULTS PCT, IAP, CRP values and APACHE II score at 24 h after hospital admission were significantly elevated in patients with SAP. There was significant correlation between PCT and IAP values measured at 24 h of admission, and between maximal PCT and IAP values. Sensitivity/specificity for predicting AP severity at 24 h after admission was 89%/69% for APACHE II score, 75%/86% for CRP, 86%/63% for PCT and 75%/77% for IAP. CONCLUSIONS Increased IAP was accompanied by increased PCT serum concentration in patients with AP. PCT and IAP can both be used as early markers of AP severity.

Abstract
BACKGROUND/AIMS The aim of this study is to assess serum procalcitonin (PCT) for early prediction of severe acute pancreatitis compared with multiple scoring systems and biomarkers. METHODS Forty-four patients with acute pancreatitis confirmed by radiological evidences, laboratory assessments, and clinical manifestation were prospectively enrolled. All blood samples and image studies were obtained within 24 hours of admission. RESULTS Acute pancreatitis was graded as severe in 19 patients and mild in 25 patients according to the Atlanta criteria. Levels of serum PCT were significantly higher in severe acute pancreatitis (p=0.001). The accuracy of serum PCT as a predicting marker was 77.3%, which was similar to the acute physiology and chronic health examination (APACHE)-II score, worse than the Ranson score (93.2%) and better than the Balthazar CT index (65.9%). The most effective cut-off level of serum PCT was estimated at 1.77 ng/mL (AUC=0.797, 95% CI=0.658-0.935). In comparision to other simple biomarkers, serum PCT had more accurate value (77.3%) than C-reactive protein (68.2%), urea (75.0%) and lactic dehydrogenase (72.7%). Logistic regression analysis revealed that serum PCT has statistical significance in acute severe pancreatitis. Assessment of serum PCT levels and length of hospital stay by simple linear regression analysis revealed effective p-value with low R square level, which could make only possibilty for affection of serum PCT to admission duration (r2=0.127, p=0.021). CONCLUSIONS Serum PCT was a promising simple biomarker and had similar accuracy of APACHE-II scores as predicting severity of acute pancreatitis.

Abstract
Acute pancreatitis (AP) is an important cause of morbidity and mortality worldwide and the annual incidence appears to be increasing. It presents as a mild self-limiting illness in 80% of patients. However, one-fifth of these develop a severe complicated life-threatening disease requiring intensive and prolonged therapeutic intervention. Alcohol and gallstone disease remain the commonest causes of AP but metabolic abnormalities, obesity and genetic susceptibility are thought be increasingly important aetiological factors. The prompt diagnosis of AP and stratification of disease severity is essential in directing rapid delivery of appropriate therapeutic measures. In this review, the range of diagnostic and prognostic assays, severity scoring systems and radiological investigations used in current clinical practice are described, highlighting their strengths and weaknesses. Increased understanding of the complex pathophysiology of AP has generated an array of new potential diagnostic assays and these are discussed. The multidisciplinary approach to management of severe pancreatitis is outlined, including areas of controversy and novel treatments.

Abstract
BACKGROUND Urinary tract infection (UTI) is a common problem in children. The aim of this study was to determine the usefulness of the procalcitonin (PCT) rapid test in the diagnosis of renal involvement in children with urinary tract infection. METHODS Through a case series study, PCT and C-reactive protein rapid tests were measured in children with proven UTI at the Tehran Children's Medical Center, Iran. One-hundred patients aged 1 month-14 years old (19 boys and 81 girls) with documented UTI were enrolled in the study. RESULTS Of 100 children, 62 patients (62%) had renal involvement on the basis of abnormal Tc-dimercaptosuccinic acid scintigraphy and 38 patients (38%) had infection restricted to the lower urinary tract. There were no differences related to age or gender among the groups. The sensitivity and specificity of PCT were 77% and 89%, respectively, in prediction of renal involvement, whereas C-reactive protein had a sensitivity of 80% and a specificity of 65%. CONCLUSION We concluded that a rapid determination of PCT concentration could be useful for the management of children with febrile UTI in the emergency room.

Buhaescu I, Yood RA, Izzedine H. Serum procalcitonin in systemic autoimmune diseases--where are we now? Semin Arthritis Rheum 2010; 40:176-83.

Abstract
OBJECTIVES To review the current evidence regarding the value of measuring procalcitonin (PCT) levels in patients with systemic autoimmune diseases, with a focus on the evidence for diagnostic and analytical performance of this biomarker. A brief description of the pathophysiological basis of this biomarker is also included. METHODS Using PubMed from the National Library of Medicine, relevant English literature on PCT in patients with different systemic autoimmune diseases, from 1990 to 2009, was reviewed. The search used keywords referring to procalcitonin and systemic lupus erythematosus, antineutrophil cytoplasmic antibody-associated systemic vasculitis, Goodpasture syndrome, rheumatoid arthritis, and giant cell arteritis. RESULTS When used in the appropriate clinical setting, the measurement of serum PCT levels is valuable as a marker of severe systemic bacterial and fungal infections and sepsis. Information regarding plasma PCT levels in patients with active underlying systemic autoimmune diseases is limited, primarily from observational studies and case series, with considerable variability of patient characteristics and clinical settings. In the detection of systemic infection concomitant with autoimmune diseases, PCT had a diagnostic sensitivity of 53 to 100% and a specificity of 84 to 97% (depending on the selection criteria) and was superior to other inflammatory markers tested. Most of the studies used a semiquantitative test for PCT measurement (functional assay sensitivity <0.5 ng/mL), which can explain the low sensitivity of the test. PCT levels were not significantly affected by renal function abnormalities or immunosuppressive agents. Although high PCT levels commonly occurred with infection, elevated levels of PCT could be found in patients with vasculitis without evidence of infection, often correlated with high disease activity scores. CONCLUSIONS Significantly elevated PCT levels offer good specificity and sensitivity for systemic infection in patients with systemic autoimmune diseases, regardless of the use of corticosteroids or immunosuppressive agents. PCT measurement may add to diagnostic accuracy in patients with systemic autoimmune diseases who present with a febrile illness, especially when highly sensitive PCT assays and specific PCT cutoff ranges are used in a predefined clinical setting (reflecting the likelihood of infection versus an autoimmune disease flare). However, there are limitations when using this biomarker in patients with systemic autoimmune diseases. PCT levels should not replace the necessary extensive diagnostic workup, which should include a thorough history and physical examination, combined with appropriate immunological, microbiological, radiological, and histological data.

Abstract
Acute pancreatitis has a variable etiology and natural history, and some patients have severe complications with a significant risk of death. The prediction of severe disease should be achieved by careful ongoing clinical assessment coupled with the use of a multiple factor scoring system and imaging studies. Over the past 30 years several scoring systems have been developed to predict the severity of acute pancreatitis. However, there are no complete scoring index with high sensitivity and specificity till now. The interest in new biological markers and predictive models for identifying severe acute pancreatitis testifies to the continued clinical importance of early severity prediction. Among them, IL-6, IL-10, procalcitonin, and trypsinogen activation peptide are most likely to be used in clinical practice as predictors of severity. Even if contrast-enhanced CT has been considered the gold standard for diagnosing pancreatic necrosis, early scanning for the prediction of severity is limited because the full extent of pancreatic necrosis may not develop within the first 48 hour of presentation.

Abstract
BACKGROUND Many studies have evaluated serum levels of procalcitonin (PCT) as a predictor in the development of severe acute pancreatitis (SAP) and infected pancreatic necrosis (IPN). This study assesses the value of PCT as a marker of development of SAP and IPN. METHODS Medline, Web of Science, the Cochrane clinical trials register, and international conference proceedings were searched systematically for prospective studies, which evaluated the usefulness of PCT as a marker of SAP and IPN. The sensitivity, specificity, and diagnostic odds ratios (DORs) were calculated for each study, and the study quality and heterogeneity among the studies were evaluated. RESULTS Twenty-four of 59 studies identified were included in data extraction. The sensitivity and specificity of PCT for development of SAP were 0.72 and 0.86, respectively (area under the curve [AUC] = 0.87; DOR = 14.9; 95% confidence interval [CI] = 5.6-39.8), albeit with a significant degree of heterogeneity (Q = 28.56, P < .01). The sensitivity and specificity of PCT for prediction of infected pancreatic necrosis were 0.80 and 0.91 (AUC = 0.91; DOR = 28.3; 95% CI = 13.8-58.3) with no significant heterogeneity (Q = 7.83, P = .18). No significant heterogeneity was observed among the studies when only higher quality studies (AUC = 0.91; DOR = 30.7; 95% CI = 10.7-87.8) or studies that used a cutoff PCT level >0.5 ng/mL (AUC = 0.88, 32.8; 95% CI = 10.1-106.6) were included. CONCLUSION Serum measurements of PCT may be valuable in predicting the severity of acute pancreatitis and the risk of developing infected pancreatic necrosis.

Abstract
BACKGROUND/AIMS At present, there is no simple test for predicting severity in acute pancreatitis. We investigated the use of an assay of soluble E-cadherin (sE-cadherin). METHODS Concentrations of sE-cadherin, from 19 patients with mild acute pancreatitis, 7 patients with severe acute pancreatitis, 11 patients with other acute gastrointestinal pathologies, and 12 healthy subjects were measured using a commercially available sandwich ELISA kit based on two monoclonal antibodies specific to the extracellular fragment of human E-cadherin. Measurements were made at 12 hours or less from onset of pain and also at 24 and 48 hours after onset of pain. RESULTS Mean (standard deviation) concentration of sE-cadherin in patients with severe acute pancreatitis at <12 hours was 17780 ng/mL (7853), significantly higher than that of healthy volunteers 5180 ng/mL (1350), P = .0039, patients with other gastrointestinal pathologies 7358 ng/mL (6655), P = .0073, and also significantly higher than that of patients with mild pancreatitis, 7332 ng/mL (2843), P = .0019. DISCUSSION Serum sE-cadherin could be an early (within 12 hours) objective marker of severity in acute pancreatitis. This molecule warrants further investigation in the form of a large multicentre trial.

Abstract
BACKGROUND Acute pancreatitis has a variable natural history and in a proportion of patients is associated with severe complications and a significant risk of death. The various tools available for risk assessment in acute pancreatitis are reviewed. METHODS Relevant medical literature from PubMed, Ovid, Embase, Web of Science and The Cochrane Library websites to May 2008 was reviewed. RESULTS AND CONCLUSION Over the past 30 years several scoring systems have been developed to predict the severity of acute pancreatitis in the first 48-72 h. Biochemical and immunological markers, imaging modalities and novel predictive models may help identify patients at high risk of complications or death. Recently, there has been a recognition of the importance of the systemic inflammatory response syndrome and organ dysfunction.

Abstract
OBJECTIVES Of patients with acute pancreatitis (AP), 20% develop severe attacks that need early and intensive therapy. Yet, to administer such treatment, it is important to classify early on the patients with mild and severe pancreatitis. The aim of this study was to evaluate the role of serum amyloid A, C-reactive protein, procalcitonin, and routinely measured parameters in the early prediction of the course of AP. METHODS A total of 40 consecutive patients with AP confirmed by computed tomography were prospectively enrolled in the study-29 were graded as mild and 11 were graded as severe. Blood samples were obtained on admission and 24 hours thereafter. RESULTS Procalcitonin concentration in both measurements was significantly higher in patients with severe pancreatitis, and the cutoff level was estimated at 0.5 ng/mL. Although serum amyloid A and C-reactive protein levels rose significantly during the period of observation, these were not differentiated between both groups. Among the routinely measured parameters, a prognostic value was found for total calcium concentration, lactic dehydrogenase activity, and glucose concentration. CONCLUSIONS The best efficiency in the early prediction of severe AP would be achieved with the measurement of procalcitonin, total calcium level, and lactic acid dehydrogenase activity immediately after admission to the ward.

Abstract
Severity stratification is a critical issue in acute pancreatitis that strongly influences diagnostic and therapeutic decision making. According to the widely used Atlanta classification, "severe" disease comprises various local and systemic complications that are associated with an increased risk of mortality. However, results from recent clinical studies indicate that these complications vary in their effect on outcome, and many are not necessarily life threatening on their own. Therefore, "severe," as defined by Atlanta, must be distinguished from "prognostic," aiming at nonsurvival. In the first week after disease onset, pancreatitis-related organ failure is the preferred variable for predicting severity and prognosis because it outweighs morphologic complications. Contrast-enhanced CT and MRI allow for accurate stratification of local severity beyond the first week after symptom onset. Among the biochemical markers, C-reactive protein is still the parameter of choice to assess attack severity, although prognostic estimation is not possible. Other markers, including pancreatic protease activation peptides, interleukins-6 and -8, and polymorphonuclear elastase are useful early indicators of severity. Procalcitonin is one of the most promising single markers for assessment of major complications and prognosis throughout the disease course.

Abstract
Acute pancreatitis begins with pancreatic injury, elicits an acute inflammatory response, and encompasses a variety of potential complications in a subset of patients. Early determination of severity and risk of complications is crucial for instituting immediate interventions to improve outcome. The severity of acute pancreatitis is a function of the amount of pancreas that is injured and the intensity of the inflammatory response. Early death is mainly linked to an overwhelming inflammatory response leading to cardiovascular collapse or acute respiratory distress syndrome, whereas late death is associated with infected pancreatic necrosis and sepsis. This article reviews recent advancements in understanding the pathogenesis, immunology, and genetics of severe acute pancreatitis, and the literature on laboratory-based markers, which predict a severe clinical course and pancreatic necrosis.

Abstract
BACKGROUND Pancreatic infections and sepsis are major complications in severe acute pancreatitis (AP) with significant impact on management and outcome. We investigated the value of Procalcitonin (PCT) for identifying patients at risk to develop pancreatic infections in severe AP. METHODS A total of 104 patients with predicted severe AP were enrolled in five European academic surgical centers within 96 hours of symptom onset. PCT was measured prospectively by a semi-automated immunoassay in each center, C-reactive protein (CRP) was routinely assessed. Both parameters were monitored over a maximum of 21 consecutive days and in weekly intervals thereafter. RESULTS In contrast to CRP, PCT concentrations were significantly elevated in patients with pancreatic infections and associated multiorgan dysfunction syndrome (MODS) who all required surgery (n = 10) and in nonsurvivors (n = 8) early after onset of symptoms. PCT levels revealed only a moderate increase in patients with pancreatic infections in the absence of MODS (n = 7), all of whom were managed nonoperatively without mortality. A PCT value of > or =3.5 ng/mL on 2 consecutive days was superior to CRP > or =430 mg/L for the assessment of infected necrosis with MODS or nonsurvival as determined by ROC analysis with a sensitivity and specificity of 93% and 88% for PCT and 40% and 100% for CRP, respectively (P < 0.01). The single or combined prediction of the two major complications was already possible on the third and fourth day after onset of symptoms with a sensitivity and specificity of 79% and 93% for PCT > or =3.8 ng/mL compared with 36% and 97% for CRP > or =430 mg/L, respectively (P = 0.002). CONCLUSION Monitoring of PCT allows early and reliable assessment of clinically relevant pancreatic infections and overall prognosis in AP. This single test parameter significantly contributes to an improved stratification of patients at risk to develop major complications.

Abstract
BACKGROUND Severity prediction is difficult early in the course of acute pancreatitis. Markers of pancreatic injury, or inflammatory activation are candidate markers of severity. The aim of the present study was to assess predictive abilities of carboxypeptidase-B activation peptide (CAPAP-B) and soluble L-selectin (sL-selectin) using samples collected on admission to hospital. METHODS Patients with acute pancreatitis and disease (acute abdomen) and normal controls were studied. Samples were collected at admission and daily for 5 days. There were significant differences between mild and severe pancreatitis in urinary and plasma CAPAP-B on admission, C-reactive protein on day 3 and acute physiology and chronic health evaluation (APACHE)-II scores. Prediction of severity with CAPAP-B on admission was as good as with APACHE-II score after 48 h. Carboxypeptidase-B activation peptide was not raised in disease controls. By contrast, sL-selectin was lowered in all cases of acute pancreatitis, and in disease controls. There was no difference between mild and severe pancreatitis. CONCLUSION Urinary CAPAP-B, a marker of acinar injury, can be used to predict severity of acute pancreatitis at the time of admission to hospital, but sL-selectin has no value in this regard. The extent of acinar injury may be a more important early marker of severity than markers of inflammatory activation.

Abstract
PURPOSE This study was designed to evaluate the diagnostic accuracy of serum procalcitonin (PCT) for the diagnosis of severity in acute pancreatitis (AP), compared with routine clinical, biochemical, radiological, and combination severity scoring systems. METHODS Quantitative meta-analysis was performed on prospective studies, comparing serum PCT, against validated scoring systems for diagnosing severe AP. The sensitivity, specificity, and diagnostic odds ratio were calculated for each study. Summary receiver operating characteristic (SROC) curves and subgroup analysis were undertaken. Study quality and heterogeneity were evaluated. Meta-regression meta-analysis was used to evaluate the effect of using serum PCT in the diagnostic accuracy severity scoring in AP. RESULTS Summary receiver operating characteristic analysis of nine studies showed an overall sensitivity and specificity of 74% (range: 66%-81%) and 83% (range: 79%-87%), respectively. Overall unweighted area under the curve (AUC) was 0.91 (DOR = 16.26 95% CI: 5.68-46.60), demonstrating significant heterogeneity (Q-value = 25.32; P = 0.001). When high-quality studies alone were evaluated, there was an increase in the overall sensitivity (89%); however, specificity was similar (82%), with an overall unweighted AUC of 0.94 (DOR 41.46, 95% CI: 17.95-95.80), with no significant heterogeneity. Meta-regression analysis confirmed the significant effect of study quality on the diagnostic accuracy of severity scoring using serum PCT (P = 0.025). CONCLUSIONS The use of PCT for severity scoring in AP has a moderate sensitivity but higher specificity. However, the overall accuracy for predicting severity in AP is high. The prognosis of severity, especially early on (<48 hours from onset of symptoms), and the evaluation of potential infectious complications of AP may be the most useful factors to assess in subsequent clinical trials to identify its exact application in clinical practice in the management of AP.
