[PMID: 39125854 PMCID: PMC11311934 DOI: 10.3390/ijms25158283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2024] [Revised: 07/24/2024] [Accepted: 07/27/2024] [Indexed: 08/12/2024] Open
Abstract
Acute pancreatitis (AP) is a significant cause of morbidity, even in children, and is frequently associated with systemic manifestations. There are many cytokines involved in the inflammatory response characteristic of this disease. Interleukin 6 (IL-6) is one of the most important cytokines involved in AP, beginning from cellular injury and continuing to the systemic inflammatory response and distant organ involvement. IL-6 is a multifunctional cytokine that regulates acute-phase response and inflammation. It is produced by various cells and exerts its biological role on many cells through its high-affinity complex receptor. IL-6 has been investigated as a predicting maker for severe forms of AP. Many studies have validated the use of IL-6 serum levels in the first 48 h as a reliable marker for severe evolution and multisystemic involvement. Still, it has not been used in daily practice until now. This review discusses the main binding mechanisms by which IL-6 triggers cellular response and the AP pathogenetic mechanisms in which IL-6 is involved. We then emphasize the promising role of IL-6 as a prognostic marker, which could be added as a routine marker at admission in children with AP.

Relevance of Procalcitonin Levels as a Marker of Severity and Predictor of Mortality, Initiation and Duration of Antibiotics in Patients Admitted with Acute Pancreatitis: A Retrospective Cohort Study. Clin Exp Gastroenterol 2024; 17:31-39. [PMID: 38352170 PMCID: PMC10863456 DOI: 10.2147/ceg.s453345] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 02/07/2024] [Indexed: 02/16/2024] Open
Abstract
Introduction Procalcitonin levels have been studied to predict the benefit of adding antibiotics in a patient with acute pancreatitis. Through this study, we are searching for any possible correlation between serum procalcitonin levels and the severity of acute pancreatitis (included acute on chronic cases) to determine whether procalcitonin levels can predict a benefit from antibiotic therapy in acute pancreatitis. Methods This is a retrospective cohort study involving patients with acute pancreatitis and acute on chronic pancreatitis. We included all hospitalized patients admitted to Kern Medical from January 2020 to October 2022 with a diagnosis of acute pancreatitis in a consecutive manner. The primary outcome studied was mortality related to the pancreatitis episode. Logistic regression was used to control numerous confounders. Results Based on univariate analysis of procalcitonin, we found starting antibiotics on the day of admission statistically significant. We also found the median differences in mortality to be mildly significant (difference = 0.79, p = 0.0640) based on procalcitonin values. In a multivariate analysis of ln(procalcitonin), we found lipase (p = 0.0249), duration of antibiotics (p = 0.0009), multi-organ failure (p = 0.0045) to be statistically significant, and lactate being mildly significant in the multivariate model (p = 0.0643). Conclusion The procalcitonin level can predict the initiation of antibiotics, duration of antibiotics, multi-organ failure, and mortality in patients with acute pancreatitis.

[PMID: 38317108 PMCID: PMC10840143 DOI: 10.1186/s12876-024-03148-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 01/25/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND AND AIMS Severe acute pancreatitis (SAP) is potentially lethal. Considering the role of inflammation in the progression of acute pancreatitis (AP), this study aims to develop a model based on inflammatory indexes for identifying the presence of SAP. METHODS Overall, 253 patients with AP who were consecutively admitted between July 2018 and November 2020 were screened, of whom 60 had SAP. Systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), neutrophil-to-platelet ratio (NPR), systemic inflammation response index (SIRI), platelet-to-albumin ratio (PAR), C-reactive protein-to-albumin ratio (CAR), C-reactive protein-to-lymphocyte ratio (CLR), and triglyceride glucose (TyG) index were calculated. Multivariate logistic regression analyses were performed to identify independent risk factors of SAP. Then, inflammation-based models were established. Receiver operating characteristics (ROC) curve analyses were performed. Area under ROC curve (AUROC) was calculated. RESULTS Diabetes mellitus, fatty liver, high white blood cell count (WBC), C-reactive protein (CRP), red blood cell distribution width (RDW), procalcitonin (PCT), SII, NLR, NPR, CAR, CLR, and TyG index, and a low LMR were significantly associated with SAP. Considering the collinearity among these variables, 10 multivariate logistic regression analyses were separately performed. Finally, four independent inflammation-based models were established. Of them, the best one, which was calculated as follows: 1.204*fatty liver (yes = 1; no = 0) + 0.419*PCT + 0.005*CLR - 2.629, had an AUROC of 0.795 with a specificity of 73.4% and a sensitivity of 71.7%. CONCLUSION The inflammation-based model consisting of fatty liver, PCT, and CLR has a good diagnostic performance for SAP.

Persistently High Procalcitonin and C-Reactive Protein Are Good Predictors of Infection in Acute Necrotizing Pancreatitis: A Systematic Review and Meta-Analysis. Int J Mol Sci 2024; 25:1273. [PMID: 38279274 PMCID: PMC10816999 DOI: 10.3390/ijms25021273] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 01/09/2024] [Accepted: 01/17/2024] [Indexed: 01/28/2024] Open
Abstract
Infected necrotizing pancreatitis (INP) is associated with an increased risk of organ failure and mortality. Its early recognition and timely initiation of antibiotic therapy can save patients' lives. We systematically searched three databases on 27 October 2022. In the eligible studies, the presence of infection in necrotizing pancreatitis was confirmed via a reference test, which involved either the identification of gas within the necrotic collection through computed tomography imaging or the examination of collected samples, which yielded positive results in Gram staining or culture. Laboratory biomarkers compared between sterile necrotizing pancreatitis and INP were used as the index test, and our outcome measures included sensitivity, specificity, the receiver operating characteristic (ROC) curve and area under the ROC curve (AUC). Within the first 72 hours (h) after admission, the AUC of C-reactive protein (CRP) was 0.69 (confidence interval (CI): 0.62-0.76), for procalcitonin (PCT), it was 0.69 (CI: 0.60-0.78), and for white blood cell count, it was 0.61 (CI: 0.47-0.75). After the first 72 h, the pooled AUC of CRP showed an elevated level of 0.88 (CI: 0.75-1.00), and for PCT, it was 0.86 (CI: 0.60-1.11). The predictive value of CRP and PCT for infection is poor within 72 h after hospital admission but seems good after the first 72 h. Based on these results, infection is likely in case of persistently high CRP and PCT, and antibiotic initiation may be recommended.

Abstract
To reveal dysregulated metabolism hallmark that was associated with a severe acute pancreatitis (SAP) phenotype. In this study, LC-MS/MS-based targeted metabolomics was used to analyze plasma samples from 106 acute pancreatitis (AP) patients (34 mild, 38 moderate, and 34 severe) admitted within 48 hours from abdominal pain onset and 41 healthy controls. Temporal metabolic profiling was performed on days 1, 3, and 7 after admission. A random forest (RF) was performed to significantly determine metabolite differences between SAP and non-SAP (NSAP) groups. Mass spectrometry imaging (MSI) and immunohistochemistry were conducted for the examination of pancreatic metabolite and metabolic enzyme alterations, respectively, on necrosis and paracancerous tissues. Simultaneously determination of serum and pancreatic tissue metabolic alterations using an L-ornithine-induced AP model to discover metabolic commonalities. Twenty-two significant differential metabolites screened by RF were selected to build an accurate model for the prediction of SAP from NSAP (AUC = 0.955). Six of 22 markers were found by MSI with significant alterations in pancreatic lesions, reduced ornithine-related metabolites were also identified. The abnormally expressed arginase2 and ornithine transcarboxylase were further discovered in combination with time-course metabolic profiling in the SAP animal models, the decreased ornithine catabolites were found at a late stage of inflammation, but ornithine-associated metabolic enzymes were activated during the inflammatory process. The plasma metabolome of AP patients is distinctive, which shows promise for early SAP diagnosis. AP aggravation is linked to the activated ornithine metabolic pathway and its inadequate levels of catabolites in in-situ lesion.

Abstract
To investigate the correlation of serum pentraxin 3 (PTX-3), soluble interleukin-2 receptor (SIL-2R), C-reactive protein (CRP), procalcitonin (PCT) levels, and acute physiology and chronic health evaluation II (APACHE II) scores in patients with severe acute pancreatitis (SAP). A total of 30 patients with SAP from October 2020 to October 2021 were selected as the SAP group, and 42 patients with mild acute pancreatitis (MAP) or moderate-severe acute pancreatitis (MSAP) was selected as the control group. The serum levels of PTX-3, SIL-2R, CRP, PCT, and APACHE II scores were evaluated. The serum levels of PTX-3, SIL-2R, CRP, PCT, and APACHE II scores at admission in the SAP group were significantly higher than those in the control group (all P < .05). Spearman analysis showed that serum PTX-3, SIL-2R, CRP, and PCT levels were positively correlated with APACHE II scores (all P < .05). The mortality rate within 28 days was 26.7% in the SAP group; moreover, the serum PTX-3, SIL-2R, CRP, and PCT levels and APACHE II scores at admission in the death group were significantly higher than those in the survival group (all P < .05). The receiver operating curve showed that the combined prediction value of all indicators (PTX-3 + SIL-2R + CRP + PCT + APACHE II) was superior to the single indicators, and the diagnostic sensitivity and specificity were 90.9% and 84.2%, respectively. Serum PTX-3, SIL-2R, CRP, and PCT levels and APACHE II scores have high guiding significance in early diagnosis and prognostic evaluation of SAP patients.

Abstract
Background Acute necrotizing pancreatitis (NP), a severe form of acute pancreatitis (AP), has higher mortality and worse outcome than non-necrotizing pancreatitis (non-NP). Infected NP is a devastating subgroup of NP. To date neither NP nor infected NP has robust prediction strategies, which may delay early recognition and timely intervention. Recent studies revealed correlations between disturbed gut microbiota and AP severity. Some features of intestinal microbiota have the potential to become biomarkers for NP prediction. Methods We performed 16S rRNA sequencing to analyze gut microbiota features in 20 healthy controls (HC), and 58 AP patients on hospital admission. The AP patients were later classified into NP and non-NP groups based on subsequent diagnostic imaging features. Random forest regression model and ROC curve were applied for NP and infected NP prediction. PIRCUSt2 was used for bacterial functional pathway prediction analysis. Results We found that the three groups (HC, NP, and non-NP) had distinct microorganism composition. NP patients had reduced microbial diversity, higher abundance of Enterobacteriales, but lower abundance of Clostridiales and Bacteroidales compared with the non-NP group. Correlation analyses displayed that intestine bacterial taxonomic alterations were related to severity, ICU admission, and prognosis. By pathway prediction, species more abundant in NP patients had positive correlation with synthesis and degradation of ketone bodies, and benzoate degradation. Enterococcus faecium (ASV2) performed best in discriminating NP and non-NP patients. Finegoldia magna (ASV3) showed the maximal prediction capacity among all ASVs and had comparable accuracy with Balthazar CT to detect patients with infected NP. Conclusions Our study suggests that NP patients have distinct intestinal microbiota on admission compared to non-NP patients. Dysbiosis of intestinal microbiota might influence NP progression through ketone body or benzoate metabolism. Enterococcus faecium and Finegoldia magna are potential predictors for NP and infected NP. Our findings explore biomarkers which may inform clinical decision-making in AP and shed light on further studies on NP pathophysiology and management.

The role of procalcitonin as a prognostic factor for acute cholangitis and infections in acute pancreatitis: a prospective cohort study from a European single center. HPB (Oxford) 2022; 24:875-884. [PMID: 34802942 DOI: 10.1016/j.hpb.2021.10.016] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 10/16/2021] [Accepted: 10/27/2021] [Indexed: 12/12/2022]
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
PURPOSE Acute pancreatitis is a potentially life-threatening condition with a wide spectrum of clinical presentation and illness severity. An infection of pancreatic necrosis (IPN) results in a more than twofold increase in mortality risk as compared with patients with sterile necrosis. We sought to identify prognostic factors for the development of IPN among adult patients with severe or necrotizing pancreatitis. METHODS We conducted this prognostic review in accordance with systematic review methodology guidelines. We searched six databases from inception through March 21, 2021. We included English language studies describing prognostic factors associated with the development of IPN. We pooled unadjusted odds ratio (uOR) and adjusted odds ratios (aOR) for prognostic factors using a random-effects model. We assessed risk of bias using the Quality in Prognosis Studies tool and certainty of evidence using the GRADE approach. RESULTS We included 31 observational studies involving 5,210 patients. Factors with moderate or higher certainty of association with increased IPN risk include older age (uOR, 2.19; 95% confidence interval [CI], 1.39-3.45, moderate certainty), gallstone etiology (aOR, 2.35; 95% CI, 1.36-4.04, high certainty), greater than 50% necrosis of the pancreas (aOR, 3.61; 95% CI, 2.15-6.04, high certainty), delayed enteral nutrition (aOR, 2.09; 95% CI, 1.26-3.47, moderate certainty), multiple or persistent organ failure (aOR, 11.71; 95% CI, 4.97-27.56, high certainty), and invasive mechanical ventilation (uOR, 12.24; 95% CI, 2.28-65.67, high certainty). CONCLUSION This meta-analysis confirms the association between several clinical early prognostic factors and the risk of IPN development among patients with severe or necrotizing pancreatitis. These findings provide the foundation for the development of an IPN risk stratification tool to guide more targeted clinical trials for prevention or early intervention strategies. LEVEL OF EVIDENCE Systematic review and meta-analysis, Level IV.

Oxid Comparative Analysis of the Significance of Bisap and Mews Score for an Early Assessment of Illness Severity and Treatment Outcome of Acute Pancreatitis. SERBIAN JOURNAL OF EXPERIMENTAL AND CLINICAL RESEARCH 2021. [DOI: 10.2478/sjecr-2019-0013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Abstract
The aim of this study was to determine the significance of the use of the BISAP score, which is specific for patients with AP, in relation to the application of the MEWS score that is important for assessing the condition of critically ill patients in intensive care units, but is not specific for patients with AP. The research was conducted as a cohort prospective study and included patients of both sexes, older than 18 and diagnosed with AP. BISAP and MEWS score were monitored at least at four time points: on admission to the hospital (zero), 48 hours, 72 hours and 7 days after admission to the hospital.
High levels of discrimination between patients with fatal outcome and cured patients are determined in both cases, with discrimination at MEWS being somewhat higher than BISAP score. The BISAP0 had the best discrimination for BISAP score, AUROC (0.807) and also MEWS0 for MEWS score, AUROC (0.899). In our research, the highest sensitivity was shown by BISAP7d (92.1%) and MEWS48 (88.1%), and a high specificity of 87.5% had BISAP score, 48h, 72h and MEWS score at all four points of measurement.
BISAP score has a better prognostic value in relation to the form of pancreatitis, the development of complications and the outcome. However, the calculation of the MEWS score is based on monitoring the basic vital parameters so that its application is much simpler and does not require additional costs.

Atherogenic Index of Plasma Is a Potential Biomarker for Severe Acute Pancreatitis: A Prospective Observational Study. J Clin Med 2020; 9:jcm9092982. [PMID: 32942753 PMCID: PMC7565847 DOI: 10.3390/jcm9092982] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 09/11/2020] [Accepted: 09/14/2020] [Indexed: 02/07/2023] Open
Abstract
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.

Abstract
BACKGROUND In recent decades, an increasing number of patients have received minimally invasive intervention for infected pancreatic necrosis (IPN) because of the benefits in reducing postoperative multiple organ failure and mortality. However, there are limited published data regarding infection recurrence after treatment of this patient population.
AIM To investigate the incidence and prediction of infection recurrence following successful minimally invasive treatment in IPN patients.
METHODS Medical records for 193 IPN patients, who underwent minimally invasive treatment between February 2014 and October 2018, were retrospectively reviewed. Patients, who survived after the treatment, were divided into two groups: one group with infection after drainage catheter removal and another group without infection. The morphological and clinical data were compared between the two groups. Significantly different variables were introduced into the correlation and multivariate logistic analysis to identify independent predictors for infection recurrence. Sensitivity and specificity for diagnostic performance were determined.
RESULTS Of the 193 IPN patients, 178 were recruited into the study. Of them, 9 (5.06%) patients died and 169 patients survived but infection recurred in 13 of 178 patients (7.30%) at 7 (4-10) d after drainage catheters were removed. White blood cell (WBC) count, serum C-reactive protein (CRP), interleukin-6, and procalcitonin levels measured at the time of catheter removal were significantly higher in patients with infection than in those without (all P < 0.05). In addition, drainage duration and length of the catheter measured by computerized tomography scan were significantly longer in patients with infection (P = 0.025 and P < 0.0001, respectively). Although these parameters all correlated positively with the incidence of infection (all P < 0.05), only WBC, CRP, procalcitonin levels, and catheter length were identified as independent predictors for infection recurrence. The sensitivity and specificity for infection prediction were high in WBC count (≥ 9.95 × 109/L) and serum procalcitonin level (≥ 0.05 ng/mL) but moderate in serum CRP level (cut-off point ≥ 7.37 mg/L). The catheter length (cut-off value ≥ 8.05 cm) had a high sensitivity but low specificity to predict the infection recurrence.
CONCLUSION WBC count, serum procalcitonin, and CRP levels may be valuable for predicting infection recurrence following minimally invasive intervention in IPN patients. These biomarkers should be considered before removing the drainage catheters.

Abstract
PURPOSE The present study aimed to research the relationships between arterial lactate levels and pancreatic infection in moderately severe acute pancreatitis. METHODS This study retrospectively analyzed data from 503 patients with moderately severe acute pancreatitis from January 1, 2013, to March 31, 2018. The baseline characteristics on admission were compared between patients with and without elevated arterial lactate levels. The parameters and laboratory data were compared between patients with and without pancreatic infections at admission. Univariate and multivariate logistic regression analyses were used to assess the value of elevated arterial lactate levels for identifying high-risk patients. P ≤ 0.05 was considered statistically significant. RESULTS A total of 49 (9.2%) patients were diagnosed with pancreatic infections. Compared with patients without pancreatic infections, pancreatic infection patients had significantly increased arterial lactate levels at admission (1.5 ± 0.7 vs. 2.5 ± 0.9; P < 0.01). Multivariate logic analysis still showed that higher arterial lactate levels in moderately severe acute pancreatitis was an independent risk factor for developing pancreatic infections (hazard ratio: 6.31, 95% CI 3.01-13.24; P < 0.01). Arterial lactate level ≥2.1 mmol/L and procalcitonin level ≥0.5 ng/mL at admission had area under the receiver operating characteristic curves of 0.83 and 0.72, with sensitivity of 67.2% and 87%, and specificity of 82.0% and 60%, respectively, for the prediction of pancreatic infection in moderately severe acute pancreatitis. CONCLUSIONS Our results indicate that a higher arterial lactate level is independently associated with pancreatic infection in patients with moderately severe acute pancreatitis and may be used as a tool to identify high-risk patients.

Abstract
Background Predicting severe acute pancreatitis (AP) in the early clinical stage is important for low morbidity and mortality. Delta neutrophil index (DNI) is used to detect infection and inflammation, but no previous studies have evaluated the usefulness of DNI as an early predictor of progression to severe AP (SAP). Methods The medical records of patients who were diagnosed with AP at the emergency department (ED) of Wonju Severance Christian Hospital from January 2012 to August 2016 were retrospectively reviewed. The initial DNI obtained in the ED was compared with other inflammatory markers to predict SAP. Multivariate logistic regression was used for statistical analysis. Results Of the 209 cases included in the analysis, 13 were classified as SAP. Compared to the DNI of the mild to moderately SAP group, that in the SAP group was considerably higher. The DNI showed a positive correlation with the Atlanta classification and bedside index of severity in AP. Using multivariate logistic regression analysis, DNI was an independent predictor of early SAP detection (odds ratio 1.122, 95% CI 1.045-1.205, p = 0.001). Among the biomarkers, DNI had the highest predictive value for SAP. Conclusions The DNI measured in the ED at presentation is a potentially useful adjunctive marker to predict SAP.

New Risk Factors for Infected Pancreatic Necrosis Secondary to Severe Acute Pancreatitis: The Role of Initial Contrast-Enhanced Computed Tomography. Dig Dis Sci 2019; 64:553-560. [PMID: 30465178 DOI: 10.1007/s10620-018-5359-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Accepted: 10/29/2018] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIMS Pancreatic necrosis is a risk factor for poor prognosis of acute pancreatitis (AP). However, the associations between the findings on initial contrast-enhanced computed tomography (CT) of the pancreas and infected pancreatic necrosis (IPN) are unclear. METHODS This was a retrospective cohort study. Patients with severe AP (SAP) from January 2014 to December 2016 at the First Affiliated Hospital of Nanchang University were enrolled and assigned to an IPN group and a non-IPN group. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and IPN development. A receiver operating characteristic (ROC) curve was generated for the qualified independent risk factor. RESULTS Forty-two patients with IPN were compared with 100 patients without IPN. Contrast-enhanced CT was performed 7 (range 3-10) days after AP onset. Multivariate stepwise logistic regression analyses showed that the number of acute peripancreatic fluid collections (APFCs) (OR 1.328, P = 0.006), presence of peripancreatic and pancreatic parenchymal necrosis (OR 4.001, P = 0.001), and gastrointestinal wall thickening (OR 3.353, P = 0.006) were independent risk factors for IPN secondary to SAP. The area under an ROC curve for the number of APFCs was 0.714, the sensitivity was 78.60%, and the specificity was 57.30% at a cutoff value of 4.5. CONCLUSIONS The number of APFCs, presence of peripancreatic and pancreatic parenchymal necrosis, and gastrointestinal wall thickening were independent risk factors associated with IPN. As initial contrast-enhanced CT (about 7 days from AP onset) plays an important role in predicting IPN, it is important for clinicians to consider initial imaging of the pancreas.

Abstract
Objective The primary objective of this article is to identify risk factors for infected pancreatic necrosis (IPN) in patients admitted to the intensive care unit (ICU) for severe acute pancreatitis. We also described outcomes of IPN. Background Acute pancreatitis is common and associated with multiple, potentially life-threatening complications. Over the last decade, minimally invasive procedures have been developed to treat IPN. Methods We retrospectively studied consecutive patients admitted for severe acute pancreatitis to the ICUs of the Nantes University Hospital in France, between 2012 and 2015. Logistic regression was used to evaluate potential associations linking IPN to baseline patient characteristics and outcomes. Results Of the 148 included patients, 26 (17.6%) died. IPN developed in 62 (43%) patients and consistently required radiological, endoscopic, and/or surgical intervention. By multivariate analysis, factors associated with IPN were number of organ failure (OF) (for ≥ 3: OR, 28.67 (6.23-131.96), p < 0.001) and portosplenomesenteric venous thrombosis (OR, 8.16 (3.06-21.76)). Conclusion IPN occurred in nearly half our ICU patients with acute pancreatitis and consistently required interventional therapy. Number of OFs and portosplenomesenteric venous thrombosis were significantly associated with IPN. Early management of OF may reduce IPN incidence, and management of portosplenomesenteric venous thrombosis should be investigated.

Abstract
BACKGROUND AND AIM Predicting severe pancreatitis is important for early aggressive management of patients with acute pancreatitis (AP). Despite the established role of diabetes mellitus (DM) in the risk of AP, the impact of DM on the clinical outcome in AP has not been fully elucidated. The objective of this study was to assess the risk of mortality and severity in AP among patients with type-2 DM. METHODS Patients diagnosed with first attacks of AP were enrolled from January 2013 to June 2015. RESULTS A total of 201 patients (63.2% male, mean age, 59.4 y) with AP were included. Etiologies included gallstones (51.2%), alcohol (37.3%), hypertriglyceridemia (2%), and idiopathic causes (9.5%). There were 54 AP patients (26.9%) with type-2 DM. Severity indices in AP, such as Atlanta Classification (severe), Ranson score, and Bedside Index of Severity in Acute Pancreatitis, were higher in subjects with DM than those without DM. Prevalence of intensive care unit admission and mortality were higher in AP patients with DM compared with those without DM. The association between DM and increased risk of mortality in AP remained statistically significant even after adjustments for confounding factors and Atlanta Classification (odds ratio, 7.76, 95% confidence interval, 1.26-47.63, P=0.027). CONCLUSIONS Type-2 DM was associated with severity and increased mortality in patients with AP. Our findings provide evidence of the potential role of DM in the pathogenesis and management of severe AP.

Abstract
OBJECTIVES The aims of this study were to assess whether copeptin, pro-atrial natriuretic peptide, proadrenomedullin, and cortisol are associated with disease severity in patients with acute pancreatitis (AP) and to compare their ability in predicting organ failure or death. METHODS From April 2011 to January 2015, 142 patients with AP were included in this prospective single-center study and observed for 4 days. Disease severity was rated by the Atlanta 1992 and 2012 criteria and organ failure by the modified Marshall score. The aforementioned laboratory markers, C-reactive protein, and procalcitonin were measured. RESULTS Patients with moderate to severe AP showed significantly higher plasma concentrations of all biomarkers than did those with mild AP. Overall, 30 organ failures or deaths occurred. All biomarkers except cortisol had only modest discriminatory ability, with areas under the receiver operating characteristic curve (AUCs) between 0.44 and 0.66. Cortisol showed an AUC of 0.78 compared with the Acute Physiology and Chronic Health Evaluation II score with an AUC of 0.75. CONCLUSIONS Cortisol was the best predictor of organ failure or death. All biomarkers were associated with disease severity to a similar degree as C-reactive protein, the criterion-standard marker in AP. Further studies are warranted to define their clinical role.

Utilizing Multiparameter Scores and Procalcitonin as Prognosis Markers for the Degree of Severity of Acute Pancreatitis. CURRENT HEALTH SCIENCES JOURNAL 2017; 43:311-317. [PMID: 30595895 PMCID: PMC6286460 DOI: 10.12865/chsj.43.04.04] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/04/2017] [Accepted: 12/16/2017] [Indexed: 01/21/2023]
Abstract
ABSTRACT: Aim: Corroborating the Ranson, Marshall, computer tomography severity index
(EPIC score) multiparameter tests with the biological marker procalcitonin in
order to establish the degree of severity of acute pancreatitis for therapeutic
management and rate of complications. Material and method: 20 patients were
surveyed, diagnosed with acute pancreatitis in the surgery clinic of the
Military Emergency Hospital Dr. Ștefan Odobleja, between 2016-2017, with the aim
of determining the clinical, etiological and severity diagnosis by corroborating
the multiparameter scores with the plasma level of procalcitonin. Results:
Following the use of multiparameter scores to identify the degree of severity of
acute pancreatitis, we established that the best prediction is achieved by the
Ranson score and the computer tomography severity index (EPIC score), with an
accuracy of 90% . As for the values of the correlation coefficient, this
was highly significant when correlating Ranson score and procalcitonin (r
= 0.918). Other correlations were also highly significant, with values of
r = 0.797 when correlating EPIC score and procalcitonin, and r = 0.736
when correlating Marshall score with procalcitonin. Conclusion: Our study
achieved an early identification of the severe form of acute pancreatitis, by
using the multiparameter tests and the biologic marker procalcitonin, allowing
for the appropriate therapy to be implemented and thus decreasing the
complication rate of this pathological entity. Levels of serum procalcitonin
exceeded the normal limit of 2 ng/ml for 37.5% of the intermediate -
severe form patients, and for 100% of the severe form patients. The
levels of procalcitonin were highly correlated with the Ranson score, with a
slightly lower correlation for the Marshall and EPIC scores.

Abstract
Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

HPB (Oxford) 2017; 19:874-880.

Abstract
BACKGROUND Using revised Atlanta classification defined outcomes, we compare absolute values in C-reactive protein (CRP), with interval changes in CRP, for severity stratification in acute pancreatitis (AP). METHODS A retrospective study of all first incidence AP was conducted over a 5-year period. Interval change in CRP values from admission to day 1, 2 and 3 was compared against the absolute values. Receiver-operator characteristic (ROC) curve and likelihood ratios (LRs) were used to compare ability to predict severe and mild disease. RESULTS 337 cases of first incidence AP were included in our analysis. ROC curve analysis demonstrated the second day as the most useful time for repeat CRP measurement. A CRP interval change >90 mg/dL at 48 h (+LR 2.15, -LR 0.26) was equivalent to an absolute value of >150 mg/dL within 48 h (+LR 2.32, -LR 0.25). The optimal cut-off for absolute CRP based on new, more stringent definition of severity was >190 mg/dL (+LR 2.72, -LR 0.24). CONCLUSION Interval change in CRP is a comparable measure to absolute CRP in the prognostication of AP severity. This study suggests a rise of >90 mg/dL from admission or an absolute value of >190 mg/dL at 48 h predicts severe disease with the greatest accuracy.

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
Intracranial infection is a common clinical complication after craniotomy. We aimed to explore the diagnostic and prognostic value of dynamic changing procalcitonin (PCT) in early intracranial infection after craniotomy. A prospective study was performed on 93 patients suspected of intracranial infection after craniotomy. Routine peripheral venous blood was collected on the day of admission, and C reactive protein (CRP) and PCT levels were measured. Cerebrospinal fluid (CSF) was collected for routine biochemical, PCT and culture assessment. Serum and CSF analysis continued on days 1, 2, 3, 5, 7, 9, and 11. The patients were divided into intracranial infection group and non-intracranial infection group; intracranial infection group was further divided into infection controlled group and infection uncontrolled group. Thirty-five patients were confirmed with intracranial infection after craniotomy according to the diagnostic criteria. The serum and cerebrospinal fluid PCT levels in the infected group were significantly higher than the non-infected group on day 1 (P<0.05, P<0.01). The area under curve of receiver operating characteristics was 0.803 for CSF PCT in diagnosing intracranial infection. The diagnostic sensitivity and specificity of CSF PCT was superior to other indicators. The serum and CSF PCT levels have potential value in the early diagnosis of intracranial infection after craniotomy. Since CSF PCT levels have higher sensitivity and specificity, dynamic changes in this parameter could be used for early detection of intracranial infection after craniotomy, combined with other biochemical indicators.

Abstract
INTRODUCTION The development of pancreatic infection is associated with the development of a deteriorating disease with subsequent high morbidity and mortality. There is agreement that in mild pancreatitis there is no need to use antibiotics; in severe pancreatitis it would appear to be a logical choice to use antibiotics to prevent secondary pancreatic infection and decrease associated mortality. MATERIALS AND METHODS A non-systematic review of current evidence, meta-analyses and randomized controlled trials was conducted to assess the role of prophylactic antibiotics in acute pancreatitis and whether it might improve morbidity and mortality in pancreatitis. RESULTS Mixed evidence was found to support and refute the role of prophylactic antibiotics in acute pancreatitis. Most studies have failed to demonstrate much benefit from its routine use. Data from our unit suggested little benefit of their routine use, and showed that the mortality of those treated with antibiotics was significantly higher compared with those not treated with antibiotics (9% vs 0%, respectively, P = 0.043). In addition, the antibiotic group had significantly higher morbidity (36% vs 5%, respectively, P = 0.002). CONCLUSIONS Antibiotics should be used in patients who develop sepsis, infected necrosis-related systemic inflammatory response syndrome, multiple organ dysfunction syndrome or pancreatic and extra-pancreatic infection. Despite the many other factors that should be considered, prompt antibiotic therapy is recommended once inflammatory markers are raised, to prevent secondary pancreatic infection. Unfortunately, there remain many unanswered questions regarding the indications for antibiotic administration and the patients who benefit from antibiotic treatment in acute pancreatitis.

Abstract
BACKGROUND & OBJECTIVES Infected pancreatic necrosis (IPN) is associated with increased morbidity and mortality. Gut barrier dysfunction has been shown to increase the risk of bacterial translocation from the gut into the pancreatic bed. The primary aim of the study is to evaluate if ileus, a clinical marker of gut barrier dysfunction, can predict the development of IPN. METHODS A retrospective cohort study of patients with necrotizing pancreatitis (NP) was conducted from 2000 to 2014. Ileus was defined as ≥2 of the following criteria: nausea/vomiting; inability to tolerate a diet, absence of flatus, abdominal distension and features of ileus on imaging. Extensive necrosis was defined as >30% nonenhancing pancreatic parenchyma on contrast-enhanced CT. Multivariable cox proportional hazard analysis was used to evaluate known and potential predictors of IPN. RESULTS 142 patients were identified with NP, 61 with IPN and 81 with sterile necrosis. In comparison to a diagnosis of ileus documented in the medical chart, the ileus criteria had a sensitivity, specificity and positive and negative predictive value of 100%, 93%, 78% and 100%, respectively. On multivariate cox proportional hazard analysis, ileus [HR:2.6; 95%CI:1.4-4.9] and extensive necrosis [HR:2.8; 95%CI:1.3-5.8] were independently associated with the development of IPN while there was no association with bacteremia [HR:1.09; 95%CI:0.6-2.1]. CONCLUSION Ileus in NP can be accurately defined using surgical criteria. Ileus is independently associated with the future development of IPN. Further studies will be needed to determine if ileus can serve as a clinical marker to direct therapeutic interventions aimed at reducing the incidence of IPN.

Abstract
OBJECTIVES To assess the influence of infection on mortality in necrotizing pancreatitis. METHODS Eligible prospective and retrospective studies were identified through manual and electronic searches (August 2015). The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). Meta-analyses were performed with subgroup, sensitivity, and meta-regression analyses to evaluate sources of heterogeneity. RESULTS We included 71 studies (n = 6970 patients). Thirty-seven (52%) studies used a prospective design and 25 scored ≥5 points on the NOS suggesting a low risk of bias. Forty studies were descriptive and 31 studies evaluated invasive interventions. In total, 801 of 2842 patients (28%) with infected necroses and 537 of 4128 patients (13%) with sterile necroses died with an odds ratio [OR] of 2.57 (95% confidence interval [CI], 2.00-3.31) based on all studies and 2.02 (95%CI, 1.61-2.53) in the studies with the lowest bias risk. The OR for prospective studies was 2.96 (95%CI, 2.51-3.50). In sensitivity analyses excluding studies evaluating invasive interventions, the OR was 3.30 (95%CI, 2.81-3.88). Patients with infected necrosis and organ failure had a mortality of 35.2% while concomitant sterile necrosis and organ failure was associated with a mortality of 19.8%. If the patients had infected necrosis without organ failure the mortality was 1.4%. CONCLUSIONS Patients with necrotizing pancreatitis are more than twice as likely to die if the necrosis becomes infected. Both organ failure and infected necrosis increase mortality in necrotizing pancreatitis.

Abstract
OBJECTIVES We aimed to compare the prognostic value of various predictors and complex scoring systems for prediction of severe acute pancreatitis (SAP) according to the revised Atlanta classification. METHODS C-reactive protein (CRP) and procalcitonin were obtained on admission, and CRP level 24 hours after admission (CRP2) was measured. Various scoring systems including Ranson, Acute Physiology and Chronic Health Examination (APACHE II), the Bedside Index for Severity in Acute Pancreatitis, and Computed Tomography Severity Index (CTSI) were calculated. RESULTS There were 146 patients with acute pancreatitis (mean age, 50.6 ± 18.3 years; 63% male), of which 43 patients (29.5%) received a diagnosis of moderately severe AP, and 17 patients (11.6%) received a diagnosis of SAP. In patients with moderately severe acute pancreatitis to SAP, CTSI (odds ratio [OR], 10.46; 95% confidence interval [CI], 4.3-25.43; P < 0.001), APACHE II (OR, 3.87; 95% CI, 1.18-12.64; P = 0.025), and CRP2 (OR, 4.5; 95% CI, 1.53-13.1; P = 0.006) were strongly related to moderately severe acute pancreatitis and SAP. In patients with SAP compared with mild to moderately severe AP, procalcitonin (OR, 4.36; 95% CI, 1.01-18.96; P = 0.049) was the only factor strongly associated with SAP. CONCLUSIONS Procalcitonin was the best predictor for patients with SAP; CTSI, APACHE II, and CRP2 were valuable predictors for patients with moderately severe acute pancreatitis and SAP.

Abstract
Infectious diseases are among the most common reasons for admission to hospital and can easily lead to sepsis. Sepsis is globally associated with increased mortality, and although biomarkers could help clinicians in the early diagnosis of sepsis and immediate onset of antibiotics, there are always questions to be answered about their usefulness in the prognosis of infectious diseases. This article reviews some of the available biomarkers used in infectious diseases and sepsis in order to evaluate their utility to predict mortality and unfavourable outcome. Several studies present the pros and cons of each compound, but it is obvious that the ideal biomarker, with high sensitivity and specificity, cost effectiveness and with definite cut-off ranges and time of blood sampling, is yet to be found.

Abstract
Objective To observe the effect of electroacupuncture (EA) and manual acupuncture (MA) at ST25 on inflammatory mediators and nuclear factor κ-B (NF-κB) activation in rats with sodium taurocholate-induced severe acute pancreatitis (SAP). Methods Eighty-eight male Sprague–Dawley rats were randomly divided into four groups: control (sham-operated), SAP, SAP+EA and SAP+MA (n=22 each). A SAP model was established by injecting 3.5% sodium taurocholate 1 mL/kg into the pancreatic duct. In each group, animals were killed at t=3 h (n=7), 6 h (n=7) and 12 h (n=8) after the procedure. Pancreatic expression of NF-κB was examined by immunohistochemical staining. The levels of tumour necrosis factor α (TNF-α) and interleukin 6 (IL-6) in serum were determined by ELISA. Pathological changes in the pancreas were examined microscopically. Results Serum levels of TNF-α and IL-6 increased and morphological changes consistent with tissue damage were observed in the pancreas of SAP rats. NF-κB p65 expression was significantly higher in the SAP group than in the sham-operated group (p<0.05). Treatment with acupuncture at ST25 attenuated morphological damage and reduced levels of TNF-α and IL-6 in serum. NF-κB p65 expression was also significantly reduced by acupuncture at ST25 in the pancreas at 6 and 12 h after the procedure (p<0.05). There were no significant differences between the SAP+EA and SAP+MA groups. Conclusions Acupuncture at ST25 might have a therapeutic effect on rats with SAP through inhibition of NF-κB expression and a reduction in the release of pro-inflammatory cytokines.

Abstract
CONTEXT: Pancreatic necrosis is a local complication of acute pancreatitis. The development of secondary infection in pancreatic necrosis is associated with increased mortality. Pancreatic necrosectomy is the mainstay of invasive management. AIMS: Surgical approach has significantly changed in the last several years with the advent of enhanced imaging techniques and minimally invasive surgery. However, there have been only a few case series related to laparoscopic approach, reported in literature to date. Herein, we present our experience with laparoscopic management of pancreatic necrosis in 28 patients. MATERIALS AND METHODS: A retrospective study of 28 cases [20 men, 8 women] was carried out in our institution. The medical record of these patients including history, clinical examination, investigations, and operative notes were reviewed. The mean age was 47.8 years [range, 23-70 years]. Twenty-one patients were managed by transgastrocolic, four patients by transgastric, two patients by intra-cavitary, and one patient by transmesocolic approach. RESULTS: The mean operating time was 100.8 min [range, 60-120 min]. The duration of hospital stay after the procedure was 10-18 days. Two cases were converted to open (7.1%) because of extensive dense adhesions. Pancreatic fistula was the most common complication (n = 8; 28.6%) followed by recollection (n = 3; 10.7%) and wound infection (n = 3; 10.7%). One patient [3.6%] died in postoperative period. CONCLUSIONS: Laparoscopic pancreatic necrosectomy is a promising and safe approach with all the benefits of minimally invasive surgery and is found to have reduced incidence of major complications and mortality.

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
BACKGROUND Persistent organ failure and infected pancreatic necrosis are major determinants of mortality in acute pancreatitis, but there is a gap in the literature assessing the best available predictors of these two determinants. The purpose of this review was to investigate the utility of predictors of persistent organ failure and infected pancreatic necrosis in patients with acute pancreatitis, both alone and in combination. METHODS We performed a systematic search of the literature in 3 databases for prospective studies evaluating predictors of persistent organ failure, infected pancreatic necrosis, or both, with strict eligibility criteria. RESULTS The best predictors of persistent organ failure were the Japanese Severity Score and Bedside Index of Severity in Acute Pancreatitis when the evaluation was performed within 48h of admission, and blood urea nitrogen and Japanese Severity Score after 48h of admission. Systemic Inflammation Response Syndrome was a poor predictor of persistent organ failure. The best predictor of infected pancreatic necrosis was procalcitonin. CONCLUSIONS Based on the best available data, it is justifiable to use blood urea nitrogen for prediction of persistent organ failure after 48h of admission and procalcitonin for prediction of infected pancreatic necrosis in patients with confirmed pancreatic necrosis. There is no predictor of persistent organ failure that can be justifiably used in clinical practice within 48h of admission.

Abstract
AIM to evaluate the association between serum levels of procalcitonin and C-reactive protein, on the first 3 postoperative days, and the appearance of postoperative intra-abdominal infection. METHOD Prospective observational study including 67 patients operated on for colo-rectal, gastric and pancreatic cancer. Serum levels of procalcitonin and C-reactive protein were analyzed before surgery and daily until the third postoperative day. Values of procalcitonin (PCT) and C-reactive protein (CRP) were recorded as well as their accuracy for detection of postoperative intra-abdominal infection (PIAI). RESULTS The incidence of postoperative intra-abdominal infection was 13.4%. CRP serum levels at 72h, PCT serum levels at 24, 48 and 72h and the ratio between serum levels of CRP at 72hours and serum levels of CRP at 48hours (CRP D3/CRP D2) were significantly associated with the appearance of postoperative intra-abdominal infection. The highest sensitivity corresponded to PCT at 72hours (88.9%); the highest specificity and positive predictive value corresponded to the ratio CRP D3/CRP D2 (96.49% and 71.4%, respectively); the highest negative predictive value to procalcitonin at 72h and 24h. CONCLUSIONS Serum levels of PCT are significantly associated with the appearance of postoperative intra-abdominal infection. Sensitivity and predictive positive values are low, but negative predictive value is high, even at 24h after surgery.

Abstract
Biomarker-guided initiation of antibiotic therapy has been studied in four conditions: acute pancreatitis, lower respiratory tract infection (LRTI), meningitis, and sepsis in the ICU. In pancreatitis with suspected infected necrosis, initiating antibiotics best relies on fine-needle aspiration and demonstration of infected material. We suggest that PCT be measured to help predict infection; however, available data are insufficient to decide on initiating antibiotics based on PCT levels. In adult patients suspected of community-acquired LRTI, we suggest withholding antibiotic therapy when the serum PCT level is low (<0.25 ng/mL); in patients having nosocomial LRTI, data are insufficient to recommend initiating therapy based on a single PCT level or even repeated measurements. For children with suspected bacterial meningitis, we recommend using a decision rule as an aid to therapeutic decisions, such as the Bacterial Meningitis Score or the Meningitest®; a single PCT level ≥0.5 ng/mL also may be used, but false-negatives may occur. In adults with suspected bacterial meningitis, we suggest integrating serum PCT measurements in a clinical decision rule to help distinguish between viral and bacterial meningitis, using a 0.5 ng/mL threshold. For ICU patients suspected of community-acquired infection, we do not recommend using a threshold serum PCT value to help the decision to initiate antibiotic therapy; data are insufficient to recommend using PCT serum kinetics for the decision to initiate antibiotic therapy in patients suspected of ICU-acquired infection. In children, CRP can probably be used to help discontinue therapy, although the evidence is limited. In adults, antibiotic discontinuation can be based on an algorithm using repeated PCT measurements. In non-immunocompromised out- or in- patients treated for RTI, antibiotics can be discontinued if the PCT level at day 3 is < 0.25 ng/mL or has decreased by >80-90%, whether or not microbiological documentation has been obtained. For ICU patients who have nonbacteremic sepsis from a known site of infection, antibiotics can be stopped if the PCT level at day 3 is < 0.5 ng/mL or has decreased by >80% relative to the highest level recorded, irrespective of the severity of the infectious episode; in bacteremic patients, a minimal duration of therapy of 5 days is recommended.

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
AIM: To conduct a systematic evaluation of predisposing factors to infection secondary to severe acute pancreatitis (SAP).
METHODS: The clinical data for 42 patients with infection secondary to SAP who were treated from January 2000 to January 2008 at Tianjin Nankai Hospital were retrospectively analyzed. Univariate and multivariate models were used to find predisposing factors to infection secondary to SAP.
RESULTS: The interval between onset and admission (effective treatment time), APACHE-Ⅱscore, CT score, PO2, intestinal function recovery time, and BE were significantly associated with the development of secondary infection in patients with SAP (OR = 2.846, 7.286, 34.833, 0.350, 24.273, 0.194, all P < 0.05).
CONCLUSION: The time from onset to admission, APACHE-Ⅱ score, CT score, PO2, intestinal function recovery time, and BE are predisposing factors to infection secondary to SAP.

Abstract
SIGNIFICANCE Oxidative stress plays an important role in the pathogenesis of both acute and chronic pancreatitis. Although its impact is well investigated and has been studied clinically in chronic pancreatitis, it is less well defined for acute pancreatitis. RECENT ADVANCES Pathophysiological aspects of oxidative stress in acute pancreatitis have shown that reactive oxidative species (ROS) participate in the inflammatory cascade, and mediate inflammatory cell adhesion and consecutive tissue damage. Furthermore, ROS are involved in the generation of pain as another important clinical feature of patients suffering from acute pancreatitis. CRITICAL ISSUES Despite sufficient basic and experimental knowledge and evidence, the step from bench to bedside has not been successfully performed. Only a limited number of clinical studies are available that can give convincing evidence for the use of antioxidants in the clinical setting of acute pancreatitis. FUTURE DIRECTIONS Future studies are required to evaluate potential benefits of antioxidative substances to attenuate the severity of acute pancreatitis. Special focus should be put on the aspect of pain generation and the progression from mild to severe acute pancreatitis in the clinical setting.

Abstract
PURPOSE The diagnosis and treatment of secondary infection of pancreatic necrotic tissue remain a major challenge. The level of soluble triggering receptor expressed on myeloid cells (sTREM-1) in fine needle aspiration (FNA) fluid may be a good marker of infected necrosis. METHODS Patients with a clinical suspicion of secondary infection of necrotic tissue were enrolled. The serum levels of C-reactive protein, amylase, procalcitonin (PCT), and sTREM-1 and the fluid levels of sTREM-1, PCT, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and amylase were examined. When infected necrosis was defined, the first step was percutaneous or endoscopic drainage. If there was no improvement after 72 h, an open necrosectomy was performed. RESULTS In 30 patients with suspected infection, 18 patients were diagnosed as having secondary infection of necrotic tissue. The levels of sTREM-1 and PCT in FNA fluid were found to have the closest correlation with the diagnosis of infected necrosis [sTREM-1: area under the receiver operating characteristic curve (AUC) 0.972; 95% confidence interval (95%CI) 0.837-1.000; PCT: AUC 0.903; 95%CI 0.670-0.990, P > 0.05]. A fluid sTREM-1 cutoff value of 285.6 pg/ml had a sensitivity of 94.4% and a specificity of 91.7%. In a multiple logistic regression analysis, an sTREM-1 level of more than 285 pg/ml and a PCT level of more than 2.0 ng/ml in FNA fluid were independent predictors of infected necrosis. CONCLUSIONS The fluid level of sTREM-1 will help in the rapid and accurate diagnosis of secondary infection of necrotic tissue in patients with severe acute pancreatitis (SAP).

Abstract
Infection and/or sepsis biomarkers should help to make the diagnosis and thus initiate therapy earlier, help to differentiate between infectious and sterile inflammation, allow the use of more-specific antimicrobials, shorten the time of antimicrobial use, and ideally identify distinct phenotypes that may benefit from specific adjunctive sepsis therapies. Procalcitonin (PCT) was proposed as a sepsis and infection marker more than 15 years ago. Meanwhile, PCT has been evaluated in various clinical settings. In this review the present use of PCT on the ICU and in critically ill patients is summarized, included it's role for diagnosis of severe sepsis and septic shock and antibiotic stewardship with PCT.

Abstract
BACKGROUND/AIMS Artificial neural networks (ANNs) are non-linear pattern recognition techniques, which can be used as a tool in medical decision-making. The aim of this study was to construct and validate an ANN model for early prediction of the severity of acute pancreatitis (AP). METHODS Patients treated for AP from 2002 to 2005 (n = 139) and from 2007 to 2009 (n = 69) were analyzed to develop and validate the ANN model. Severe AP was defined according to the Atlanta criteria. RESULTS ANNs selected 6 of 23 potential risk variables as relevant for severity prediction, including duration of pain until arrival at the emergency department, creatinine, hemoglobin, alanine aminotransferase, heart rate, and white blood cell count. The discriminatory power for prediction of progression to a severe course, determined from the area under the receiver-operating characteristic curve, was 0.92 for the ANN model, 0.84 for the logistic regression model (p = 0.030), and 0.63 for the APACHE II score (p < 0.001). The numbers of correctly classified patients for a sensitivity of 50 and 75% were significantly higher for the ANN model than for logistic regression (p = 0.002) and APACHE II (p < 0.001). CONCLUSION The ANN model identified 6 risk variables available at the time of admission, including duration of pain, a finding not being presented as a risk factor before. The severity classification developed proved to be superior to APACHE II. and IAP.

Abstract
We report a severely infected necrotizing pancreatitis managed with hand-assisted laparoscopic necrosectomy along with a review of the relevant literature. Minimally invasive necrosectomy has been shown to be efficient and advantageous in managing necrotizing pancreatitis. Multiple techniques have been advocated over the last decade. Laparoscopic pancreatic debridement is a feasible option for some patients with necrotizing pancreatitis. We selected hand-assisted laparoscopic pancreatic necrosectomy, which has gained some favor over open necrosectomy because of the morbidity and mortality associated with laparotomy. We report on an Indian male patient who presented with acute abdomen and severe jaundice. A CT scan of the abdomen showed severe necrotizing pancreatitis. After conservative management failed, a hand-assisted laparoscopic pancreatic necrosectomy was performed. The patient recovered and was discharged 4 weeks after surgery.

Abstract
The objective of the present study was to measure serum C-reactive protein (CRP) concentrations in 32 dogs with acute abdomen syndrome at presentation and after 48-72 hr. Data were evaluated to determine if there was an association between CRP concentration and outcome, and if CRP concentration correlated with the white blood cell (WBC) count at both time points. An immunoturbidimetric assay for human CRP, previously validated for use in dogs, was used for serum CRP analysis. Increased serum CRP concentrations were found in 21 dogs at presentation. Fifteen of these dogs had declining serum CRP concentrations by 48-72 hr, but 3 of the 15 dogs were later euthanized. Serum CRP concentrations increased by 48-72 hr in 4 dogs. Of the 32 dogs, 4 were dead or were euthanized prior to the 48-72 hr time point. No significant difference between initial CRP concentration and outcome was found (P = 0.054). Initial and 48-72 hr CRP values taken together were significantly different between outcome groups (P < 0.001). Serum CRP concentrations that were elevated at both time points were associated with a poor prognosis. No correlation was found between CRP concentrations and WBC counts at presentation (P = 0.83); however, a significant correlation was noted at 48-72 hr (P = 0.03). Evaluation of sequential CRP concentrations in dogs with acute abdomen syndrome may be helpful in assessing clinical response to treatment and predicting outcome. Also, serum CRP may be better in detecting tissue injury and/or inflammation at presentation than WBC counts in select cases.

Serum profiles of C-reactive protein, interleukin-8, and tumor necrosis factor-alpha in patients with acute pancreatitis. HPB SURGERY : A WORLD JOURNAL OF HEPATIC, PANCREATIC AND BILIARY SURGERY 2010; 2009:878490. [PMID: 20130823 PMCID: PMC2814374 DOI: 10.1155/2009/878490] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2009] [Revised: 07/28/2009] [Accepted: 11/16/2009] [Indexed: 12/22/2022]
Abstract
Background-Aims. Early prediction of the severity of acute pancreatitis would lead to prompt intensive treatment resulting in improvement of the outcome. The present study investigated the use of C-reactive protein (CRP), interleukin IL-8 and tumor necrosis factor-α (TNF-α) as prognosticators of the severity of the disease.
Methods. Twenty-six patients with acute pancreatitis were studied. Patients with APACHE II score of 9 or more formed the severe group, while the mild group consisted of patients with APACHE II score of less than 9. Serum samples for measurement of CRP, IL-8 and TNF-α were collected on the day of admission and additionally on the 2nd, 3rd and 7th days.
Results. Significantly higher levels of IL-8 were found in patients with severe acute pancreatitis compared to those with mild disease especially at the 2nd and 3rd days (P = .001 and P = .014, resp.). No significant difference for CRP and TNF-α was observed between the two groups. The optimal cut-offs for IL-8 in order to discriminate severe from mild disease at the 2nd and 3rd days were 25.4 pg/mL and 14.5 pg/mL, respectively.
Conclusions. IL-8 in early phase of acute pancreatitis is superior marker compared to CRP and TNF-α for distinguishing patients with severe disease.

The value of procalcitonin at predicting the severity of acute pancreatitis and development of infected pancreatic necrosis: systematic review. Surgery 2009; 146:72-81. [PMID: 19541012 DOI: 10.1016/j.surg.2009.02.013] [Citation(s) in RCA: 113] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2008] [Accepted: 02/20/2009] [Indexed: 12/12/2022]
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
Prompt diagnosis, intervention, and risk assessment are critical in caring for septic patient but remain difficult with currently available methods. Biomarkers may become useful adjuncts to clinicians and ultimately serve as targets for future therapeutic trials in sepsis. The most relevant markers are reviewed in this article, including interleukin-6, C-reactive protein, procalcitonin, triggering receptor expressed on myeloid cells-1, and biomarker panels.

Adiponectin deficiency is associated with severe polymicrobial sepsis, high inflammatory cytokine levels, and high mortality. Surgery 2009; 145:550-7.

Abstract
BACKGROUND Adiponectin, a key substance in metabolic syndrome, is known to have anti-inflammatory properties. The relationship between adiponectin and sepsis in vivo is unclear. In this study, the possible involvement of adiponectin in polymicrobial sepsis was investigated using adiponectin-knockout (APN-KO) mice that underwent cecal ligation and puncture (CLP) and received the peroxisome proliferator-activated receptor gamma (PPAR-gamma) that increases the plasma adiponectin concentration. METHODS APN-KO and wild-type (WT) mice underwent either CLP or a sham operation. The plasma adiponectin, endotoxin, tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6) levels were determined before and at 2, 4, 6, 8, 12, 16, and 24 hours after the procedures, and the survival rates were compared. Mice were injected with rosiglitazone, a selective PPAR-gamma agonist, and compared survival rates after CLP with those without rosiglitazone. RESULTS After CLP, APN-KO mice had a significantly higher mortality than WT mice. The plasma endotoxin, TNF-alpha, and IL-6 levels in APN-KO mice were significantly higher than those in WT mice 24 hours after CLP. Within 4 hours after CLP, the plasma adiponectin level in WT mice decreased to half of the initial levels. Pre-CLP treatment with PPAR-gamma was shown to increase the plasma adiponectin level and to improve significantly mortality of WT mice during sepsis; mortality among APN-KO mice did not improve. CONCLUSION These results suggest that adiponectin deficiency may cause the high mortality and the high inflammatory cytokine levels in mice with polymicrobial sepsis.
