Assessment of early factors for identification or prediction severe acute pancreatitis in pregnancy

BACKGROUND Acute pancreatitis in pregnancy(APIP)is a rare and serious condition,and severe APIP(SAPIP)can lead to pancreatic necrosis,abscess,multiple organ dysfunction,and other adverse maternal and infant outcomes.Therefore,early identification or prediction of SAPIP is important.AIM To assess factors for early identification or prediction of SAPIP.METHODS The clinical data of patients with APIP were retrospectively analyzed.Patients were classified with mild acute pancreatitis or severe acute pancreatitis,and the clinical characteristics and laboratory biochemical indexes were compared between the two groups.Logical regression and receiver operating characteristic curve analyses were performed to assess the efficacy of the factors for identification or prediction of SAPIP.RESULTS A total of 45 APIP patients were enrolled.Compared with the mild acute pancreatitis group,the severe acute pancreatitis group had significantly increased(P<0.01)heart rate(HR),hemoglobin,neutrophil ratio(NEUT%),and neutrophil–lymphocyte ratio(NLR),while lymphocytes were significantly decreased(P<0.01).Logical regression analysis showed that HR,NEUT%,NLR,and lymphocyte count differed significantly(P<0.01)between the groups.These may be factors for early identification or prediction of SAPIP.The area under the curve of HR,NEUT%,NLR,and lymphocyte count in the receiver operating characteristic curve analysis was 0.748,0.732,0.821,and 0.774,respectively.The combined analysis showed that the area under the curve,sensitivity,and specificity were 0.869,90.5%,and 70.8%,respectively.CONCLUSION HR,NEUT%,NLR,and lymphocyte count can be used for early identification or prediction of SAPIP,and the combination of the four factors is expected to improve identification or prediction of SAPIP.

Acute pancreatitis:A review of diagnosis,severity prediction and prognosis assessment from imaging technology,scoring system and artificial intelligence

Acute pancreatitis(AP)is a potentially life-threatening inflammatory disease of the pancreas,with clinical management determined by the severity of the disease.Diagnosis,severity prediction,and prognosis assessment of AP typically involve the use of imaging technologies,such as computed tomography,magnetic resonance imaging,and ultrasound,and scoring systems,including Ranson,Acute Physiology and Chronic Health Evaluation II,and Bedside Index for Severity in AP scores.Computed tomography is considered the gold standard imaging modality for AP due to its high sensitivity and specificity,while magnetic resonance imaging and ultrasound can provide additional information on biliary obstruction and vascular complications.Scoring systems utilize clinical and laboratory parameters to classify AP patients into mild,moderate,or severe categories,guiding treatment decisions,such as intensive care unit admission,early enteral feeding,and antibiotic use.Despite the central role of imaging technologies and scoring systems in AP management,these methods have limitations in terms of accuracy,reproducibility,practicality and economics.Recent advancements of artificial intelligence(AI)provide new opportunities to enhance their performance by analyzing vast amounts of clinical and imaging data.AI algorithms can analyze large amounts of clinical and imaging data,identify scoring system patterns,and predict the clinical course of disease.AI-based models have shown promising results in predicting the severity and mortality of AP,but further validation and standardization are required before widespread clinical application.In addition,understanding the correlation between these three technologies will aid in developing new methods that can accurately,sensitively,and specifically be used in the diagnosis,severity prediction,and prognosis assessment of AP through complementary advantages.

Effect of Chaishao Chengqi Decoction on inflammation and prognosis of moderate and severe acute pancreatitis of heat stagnation and Fu-organ excess type

Objective:To explore the curative effect of Chaishao Chengqi Decoction on moderate to severe acute pancreatitis of heat stagnation and Fu-organ excess type and its effect on inflammatory reaction,and to provide new ideas for clinical treatment and prognosis evaluation.Methods:60 patients with moderate to severe acute pancreatitis of heat stagnation and Fu-organ excess type from June 2017 to June 2019 were randomly divided into control group treated with conventional therapy and treatment group treated with Chaishao Chengqi Decoction for 2 weeks.The differences of clinical efficacy and TCM syndromes between the two groups were compared.Ranson score,Balthazar CTSI score,SIRS score and modified Marshall score were recorded before and after treatment.The levels of inflammatory factors and oxidative stress-related molecules were compared before and after treatment.Result:After treatment,the total effective rates of the control group and the treatment group were 80.0%and 93.3%,respectively,with statistical difference(χ2=8.845,P=0.027);after treatment,the total effective rates of TCM syndromes evaluation of the control group and the treatment group were 76.7%and 93.3%,respectively,with statistical difference(χ2=10.024,P=0.012);after treatment,the Ranson score,Balthazar CTSI score,SIRS score and improved Marshall score were all significantly decreased(P<0.05),and the decrease was more significant in the treatment group(P<0.05);after treatment,the serum levels of TNF-α,IL-6 and MDA were significantly decreased in both groups,and superoxide dismutase(SOD)was significantly increased(P<0.05),and the treatment group improved more(P<0.05).Conclusion:Chaishao Chengqi Decoction has a good curative effect on moderate to severe acute pancreatitis of heat stagnation and Fu-organ excess type,and can effectively improve inflammatory response and oxidative stress,which has a high clinical significance.

Prognostic value of red blood cell distribution width for severe acute pancreatitis

BACKGROUND Severe acute pancreatitis(SAP)is a common condition in the intensive care unit(ICU)and has a high mortality.Early evaluation of the severity and prognosis is very important for SAP therapy.Recently,red blood cell distribution(RDW)was associated with mortality of sepsis patients and could be used as a predictor of prognosis.Similarly,RDW may be associated with the prognosis of SAP patients and be used as a prognostic indicator for SAP patients.AIM To investigate the prognostic value of RDW for SAP patients.METHODS We retrospectively enrolled SAP patients admitted to the ICU of the First Affiliated Hospital of China Medical University from June 2015 to June 2017.According to the prognosis at 90 d,SAP patients were divided into a survival group and a non-survival group.RDW was extracted from a routine blood test.Demographic parameters and RDW were recorded and compared between the two groups.The receiver operator characteristic(ROC)curve was constructed and Cox regression analysis was performed to investigate the prognostic value of RDW for SAP patients.RESULTS In this retrospective cohort study,42 SAP patients were enrolled,of whom 22 survived(survival group)and 20 died(non-survival group).The baseline parameters were comparable between the two groups.The coefficient of variation of RDW(RDW-CV),standard deviation of RDW(RDW-SD),Acute Physiology and Chronic Health Evaluation II(APACHE II)score,and Sequential Organ Failure Assessment(SOFA)score were significantly higher in the non-survival group than in the survival group(P<0.05).The RDW-CV and RDW-SD were significantly correlated with the APACHE II score and SOFA score,respectively.The areas under the ROC curves(AUCs)of RDW-CV and RDW-SD were all greater than those of the APACHE II score and SOFA score,among which,the AUC of RDW-SD was the greatest.The results demonstrated that RDW had better prognostic value for predicting the mortality of SAP patients.When the RDW-SD was greater than 45.5,the sensitivity for predicting prognosis was 77.8%and the specificity was 70.8%.Both RDW-CV and RDW-SD could be used as independent risk factors to predict the mortality of SAP patients in multivariate logistic regression analysis and univariate Cox proportional hazards regression analysis,similar to the APACHE II and SOFA scores.CONCLUSION The RDW is greater in the non-surviving SAP patients than in the surviving patients.RDW is significantly correlated with the APACHE II and SOFA scores.RDW has better prognostic value for SAP patients than the APACHE II and SOFA scores and could easily be used by clinicians for the treatment of SAP patients.

Perirenal space blocking restores gastrointestinal function in patients with severe acute pancreatitis

AIM:To investigate effects of perirenal space blocking(PSB)on gastrointestinal function in patients with severe acute pancreatitis(SAP).METHODS:Forty patients with SAP were randomly allocated to receive PSB or no PSB(NPSB).All the SAP patients received specialized medical therapy(SMT).Patients in the PSB group received PSB+SMT when hospitalized and after diagnosis,whereas patients in the NPSB group only received SMT.A modifed gastrointestinal failure(GIF)scoring system was used to assess the gastrointestinal function in SAP patients after admission.Pain severity(visual analog scale,0 to100)was monitored every 24 h for 72 h.RESULTS:Modified GIF score decreased in both groups during the 10-d study period.The median score decrease was initially significantly greater in the PSB group than in the NPSB group after PSB was per-formed.During the 72-h study period,pain intensity decreased in both groups.The median pain decrease was significantly greater in the PSB group than in the NPSB group at single time points.Patients in the PSB group had significantly lower incidences of hospital mortality,multiple organ dysfunction syndrome,systemic inflammatory response syndrome,and pancreatic infection,and stayed in the intensive care unit for a shorter duration.However,no difference in terms of operation incidence was found between the two groups.CONCLUSION:PSB could ameliorate gastrointestinal dysfunction or failure during the early stage of SAP.Moreover,PSB administration could improve prognosis and decrease the mortality of SAP patients.

Enteral nutrition in treatment of severe acute pancreatitis

Objective: To observe the role and the timing of EN inthe treatment of patients with severe acute pancreatitis(SAP).Methods: Eleven patients with severe acute pancreatitisunderwent systemic nutrition support were studied.EN was given through jejunostomy tube (or Beng-mark tube) after a period of PN maintenance. ENstarted when serum and urine amylase activity re-turned to normal with regular peristaltic sound, defe-cation or break wind. The sequence of preparationwas as follows: saline glucose→chemically defined di-et→polymeric diet→normal diet.Results: In all the patients, none died. The rate of latecomplications was lower, and the levels of serum albu-min and transferritin significantly increased in thepost-EN period as compared with the pre-EN period,although the count of lymphocytes was less changed.Conclusions: Nutritional support should be trans-formed from PN to EN as early as possible during thetreatment of patients with severe acute pancreatitis. ENcould not only continue sufficient nutritional support,but also avoid the unfavorable effects of long-timePN, thus reducing complications as well as mortality.

Effect of admission hypertriglyceridemia on the episodes of severe acute pancreatitis

AIM: To investigate the effect of admission hypertriglyceridemia (HTG) on the episodes of severe acute pancreatitis (SAP). METHODS: One hundred and seventy-six patients with SAP were divided into HTG group (n = 45) and control group (n = 131) according to admission triglyceride (TG) 5.65 mmol/L and < 5.65 mmol/L, respectively. Demographics, etiology, underlying diseases, biochemical parameters, Ranson' s score, acute physiology and chronic heath evaluation (APACHE ) score, Balthazar's computed tomography (CT) score, complications and mortality were compared. Correlation between admission TG and 24-h APACHE score was analyzed. RESULTS: SAP patients with HTG were younger (40.8 ± 9.3 years vs 52.6 ± 13.4 years, P < 0.05) with higher etiology rate of overeating, high-fat diet (40.0% vs 14.5%, P < 0.05) and alcohol abuse (46.7% vs 23.7%, P < 0.01), incidence rate of hypocalcemia (86.7% vs 63.4%, P < 0.01) and hypoalbuminemia (84.4% vs 60.3%, P < 0.01), 24-h APACHE score (13.6 ± 5.7 vs 10.7 ± 4.6, P < 0.01) and admission serum glucose (17.7 ± 7.7 vs 13.4 ± 6.1, P < 0.01), complication rate of renal failure (51.1% vs 16.8%, P < 0.01), shock (37.9% vs 14.5%, P < 0.01) and infection (37.4% vs 18.3%, P < 0.01) and mortality (13.1% vs 9.1%, P < 0.01). Logistic regression analysis showed a positive correlation between admission TG and 24-h APACHE score (r = 0 .509, P = 0.004).CONCLUSION: The clinical features of SAP patients with HTG are largely consistent with previous studies. HTG aggravates the episodes of SAP.

Medical imaging for pancreatic diseases:Prediction of severe acute pancreatitis complicated with acute respiratory distress syndrome

In this editorial we comment on the article published in the recent issue of the World Journal of Gastroenterology[2022;28(19):2123-2136].We pay attention to how to construct a simpler and more reliable new clinical predictive model to early identify patients at high risk of acute respiratory distress syndrome(ARDS)associated with severe acute pancreatitis(SAP),and to early predict the severity of organ failure from chest computed tomography(CT)findings in SAP patients.As we all know,SAP has a sudden onset,is a rapidly changing condition,and can be complicated with ARDS and even multiple organ dysfunction syndrome,and its mortality rate has remained high.At present,there are many clinical scoring systems for AP,including the bedside index for severity in AP,acute physiology and chronic health evaluation II,systemic inflammatory response syndrome,Japanese severe score,quick sepsis-related organ failure assessment,etc.However,some of these scoring systems are complex and require multiple and difficult clinical parameters for risk stratification.Although the aforementioned biomarkers are readily available,their ability to predict ARDS varies.Accordingly,it is extremely necessary to establish a simple and valuable novel model to predict the development of ARDS in AP.In addition,the extra-pancreatic manifestations of AP patients often involve the chest,among which pleural effusion and pulmonary consolidation are the more common complications.Therefore,by measuring the semi-quantitative indexes of chest CT in AP patients,such as the amount of pleural effusion and the number of lobes involved as pulmonary consolidation,it has important reference value for the early diagnosis of SAP complicated with ARDS and is expected to provide a basis for the early treatment of ARDS.

Impact of alanyl-glutamine dipeptide on severe acute pancreatitis in early stage

AIM:To evaluate the therapeutic effect of alanyl- glutamine dipeptide (AGD) in the treatment of severe acute pancreatitis (SAP) in early and advanced stage. METHODS: Eighty patients with SAP were randomized and received 100 mL/d of 20% AGD intravenously for 10 d starting either on the day of (early treatment group) or 5 d after (late treatment group) admission. Groups had similar demographics, underlying diseases, Ranson score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score, and Balthazar’s computed tomography (CT) score at the beginning of the study and underwent similar other medical and nutritional management. RESULTS: The duration of acute respiratory distress syndrome (2.7 ± 3.3 d vs 12.7 ± 21.0 d, P < 0.01), renal failure (1.3 ± 0.5 d vs 5.3 ± 7.3 d, P < 0.01), acute hepatitis (3.2 ± 2.3 d vs 7.0 ± 7.1 d, P < 0.01), shock (1.7 ± 0.4 d vs 4.8 ± 3.1 d, P < 0.05), encephalopathy (2.3 ± 1.9 d vs 9.5 ± 11.0 d, P < 0.01) and enteroparalysis (2.2 ± 1.4 d vs 3.5 ± 2.2 d, P < 0.01) and hospital stay (28.8 ± 9.4 d vs 45.2 ± 27.1 d, P < 0.01) were shorter in the early treatment group than in the late treatment group. The 15-d APACHE Ⅱ score was lower in the early treatment group than in the late treatment group (5.0 ± 2.4 vs 8.6 ± 3.6, P < 0.01). The infection rate (7.9% vs 26.3%, P < 0.05), operation rate (13.2% vs 34.2%, P < 0.05) and mortality (5.3% vs 21.1%, P < 0.05) in the early treatment group were lower than in the late treatment group.CONCLUSION: Early treatment with AGD achieved a better clinical outcome in SAP patients.

Role of oxygen free radicals in patients with acute pancreatitis

The generation of oxygen free radicals has been implicated in the pathogenesis of experimental pancreatitis.The aim of this study was to determine the role of oxygen free radicals in patients with acute pancreatitis.METHODS: The plasma levels of C-reactive protein (CRP),lipid peroxide (LPO), myeloperoxidase (MPO) and superoxide dismutase (SOD) were measured in 13 patients with acute pancreatitis and 14 healthy volunteers.RESULTS: Among the patients with acute pancreatitis, there were higher plasma levels of LPO and MPO and lower SOD activity in patients with severe pancreatitis than in those with mild pancreatitis. However, there was no significant difference in the serum marker of oxidative stress no matter what the etiology was. The LPO level was especially correlated with the concentration of serum CRP and CT severity index.CONCLUSION: The oxygen free radicals may be closely associated with inflammatory process and the severity of acute pancreatitis. Especially, the concentration of plasma LPO is a meaningful index for determining the severity of the disease.

BISAP评分、NIR、HCT及钙离子评估急性胰腺炎严重程度及预后的临床价值

目的:探讨急性胰腺严重床旁指数(BISAP)评分、中性粒细胞和淋巴细胞比(NLR)、红细胞比容(HCT)、血清钙离子(Ca^(2+))与急性胰腺炎(AP)严重程度和预后的关系。方法:选取371例AP患者为研究对象,根据病情分为轻症AP组(MAP组,n=220)、中度重症AP组(MSAP组,n=111)及重症AP组(SAP组,n=40);根据患者预后分为死亡组(n=15)和生存组(n=356)。比较不同病情患者临床资料(性别、年龄、住院时间、住院费用)及不同病情和预后患者实验室检查指标[中性粒细胞与淋巴细胞比值(NLR)、红细胞比容(HCT)、Ca^(2+)、AP严重程度床旁指数(BISAP)评分],分析实验室检查指标与AP严重程度和预后的关系。结果:不同病情患者NLR、HCT、Ca^(2+)、BISAP评分均有统计学差异(P<0.05),且随病情加重,NLR、HCT、BISAP评分均增加(P<0.05),Ca^(2+)水平均降低(P<0.05)。生存组患者NLR、HCT水平及BISAP评分均低于死亡组(P<0.05),Ca^(2+)水平高于死亡组(P<0.05)。ROC曲线分析显示,NLR、HCT、Ca^(2+)水平与BISAP评分预测AP患者预后死亡的曲线下面积(AUC)分别为0.857(95%CI:0.817~0.891)、0.842(95%CI:0.801~0.878)、0.806(95%CI:0.762~0.845)、0.870(95%CI:0.831~0.902);灵敏度分别为80.00%、66.67%、73.33%、93.33%,特异度分别为92.70%、93.26%、80.06%、76.40%,均对AP患者预后死亡有较好的预测价值(P<0.05)。结论:NLR、HCT及血清钙离子水平及BISAP评分指标均可辅助评估AP病情严重程度,并对患者预后有一定的预测价值。

急性胰腺炎不同部位受累的炎症活跃程度、磁共振成像及临床特征对比研究

目的:探讨急性胰腺炎(AP)胰腺不同部位受累(亚型)的炎症活跃程度、磁共振成像(MRI)表现和临床特征。方法:选取257例AP患者作为研究对象,根据胰腺不同受累部位将患者分为三组:Ⅰ型组(主要累及胰头,n=76);Ⅱ型组(主要累及胰体和胰尾,n=118)及Ⅲ型组(主要累及整个胰腺,n=63),观察并比较各组患者入院炎症活跃程度、MRI表现和临床特征。结果:Ⅲ型组入院时炎症活跃程度、病因、C反应蛋白(CRP)水平、严重程度、住院天数、坏死发生率、局部并发症及临床和影像学严重程度评分与Ⅰ型组和Ⅱ型组比较,差异有统计学意义(P<0.05)。全胰腺受累入院炎症活跃程度最高,且是最严重的亚型,主要病因是高脂血症。入院胰腺炎活跃程度评分(PASS)>140分对中重度和重度AP具有最佳预测值(AUC=0.746),且局部并发症(OR=2.58,95%CI:1.262~5.287,P=0.009)和亚型(OR=1.406,95%CI:1.065~1.857,P=0.016)是AP活跃的独立危险因素。结论:根据胰腺不同受累部位将急性胰腺炎分为三个亚型,揭示了各亚型入院时炎症活跃程度、临床和影像学特征。新的分类方法有助于更加简便从影像学维度描述AP的特征。
