Risk factors and their interactive effects on severe acute pancreatitis complicated with acute gastrointestinal injury

BACKGROUND There are many risk factors for severe acute pancreatitis(SAP)complicated with acute gastrointestinal injury(AGI),but few reports on the interaction between these risk factors.AIM To analyze the risk factors for SAP complicated with AGI and their interactive effects.METHODS We selected 168 SAP patients admitted to our hospital between December 2019 and June 2022.They were divided into AGI group and non-AGI group according to whether AGI was present.Demographic data and laboratory test data were compared between the two groups.The risk factors for SAP with concomitant AGI were analyzed using multifactorial logistic regression,and an analysis of the interaction of the risk factors was performed.RESULTS The percentage of patients with multiple organ dysfunction syndrome,acute physiological and chronic health scoring system II(APACHE II)score,white blood cell count and creatinine(CRE)level was higher in the AGI group than in the non-AGI group.There was a statistically significant difference between the two groups(P<0.05).Logistic regression analysis indicated that an APACHE II score>15 and CRE>100μmol/L were risk factors for SAP complicating AGI.The interaction index of APACHE II score and CRE level was 3.123.CONCLUSION An APACHE II score>15 and CRE level>100μmol/L are independent risk factors for SAP complicated with AGI,and there is a positive interaction between them.

Predictors of the outcomes of acute-on-chronic hepatitis B liver failure

AIM： To identify the risk factors in predicting the out- come of acute-on-chronic hepatitis B liver failure pa- tients. METHODS： We retrospectively divided 113 patients with acute-on-chronic liver failure-hepatitis B virus （ACLF-HBV） and without concurrent hepatitis C or D virus infection and hepatocellular carcinoma into two groups according to their outcomes after anti-HBV therapy. Their demographic, clinical, and biochemical data on the day of diagnosis and after the first week of treatment were analyzed using the Mann-Whitney U test, Fisher＇s exact test, and a multiple logistic regres- sion analysis. RESULTS： The study included 113 patients （87 men and 26 women） with a mean age of 49.84 years. Fifty- two patients survived, and 61 patients died. Liver failure （85.2%）, sepsis （34.4%）, and multiple organ failure （39.3%） were the main causes of death. Mul- tivariate analyses showed that Acute Physiology and Chronic Health Evaluation （APACHE） Ⅱ scores ≥ 12 [odds ratio （OR） = 7.160, 95% CI： 2.834-18.092, P 〈 0.001] and positive blood culture （OR = 13.520, 95% CI： 2.740-66.721, P = 0.001） on the day of diagnosis and model for end-stage liver disease （MELD） scores 28 （OR = 8.182, 95% CI： 1.884-35.527, P = 0.005） after the first week of treatment were independent predictors of mortality. CONCLUSION： APACHE II scores on the day of diag- nosis and MELD scores after the first week of anti-HBV therapy are feasible predictors of outcome in ACLF- HBV patients.

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.

Prediction of the severity of acute pancreatitis on admission by urinary trypsinogen activation peptide: A meta-analysis

AIM: To undertake a meta-analysis on the value of urinary trypsinogen activation peptide (uTAP) in predicting severity of acute pancreatitis on admission.METHODS: Major databases including Medline, Embase, Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in the Cochrane Library were searched to identify all relevant studies from January 1990 to January 2013. Pooled sensitivity, specificity and the diagnostic odds ratios (DORs) with 95%CI were calculated for each study and were compared to other systems/biomarkers if mentioned within the same study. Summary receiver-operating curves were conducted and the area under the curve (AUC) was evaluated.RESULTS: In total, six studies of uTAP with a cut-off value of 35 nmol/L were included in this meta-analysis. Overall, the pooled sensitivity and specificity of uTAP for predicting severity of acute pancreatitis, at time of admission, was 71% and 75%, respectively (AUC = 0.83, DOR = 8.67, 95%CI: 3.70-20.33). When uTAP was compared with plasma C-reactive protein, the pooled sensitivity, specificity, AUC and DOR were 0.64 vs 0.67, 0.77 vs 0.75, 0.82 vs 0.79 and 6.27 vs 6.32, respectively. Similarly, the pooled sensitivity, specificity, AUC and DOR of uTAP vs Acute Physiology and Chronic Health Evaluation II within the first 48 h of admission were found to be 0.64 vs 0.69, 0.77 vs 0.61, 0.82 vs 0.73 and 6.27 vs 4.61, respectively.CONCLUSION: uTAP has the potential to act as a stratification marker on admission for differentiating disease severity of acute pancreatitis.

Clinical significance of melatonin concentrations in predicting the severity of acute pancreatitis

AIM: To assess the value of plasma melatonin in predicting acute pancreatitis when combined with the acute physiology and chronic health evaluation?II?(APACHEII) and bedside index for severity in acute pancreatitis (BISAP) scoring systems.METHODS: APACHEII and BISAP scores were calculated for 55 patients with acute physiology (AP) in the first 24 h of admission to the hospital. Additionally, morning (6:00 AM) serum melatonin concentrations were measured on the first day after admission. According to the diagnosis and treatment guidelines for acute pancreatitis in China, 42 patients suffered mild AP (MAP). The other 13 patients developed severe AP (SAP). A total of 45 healthy volunteers were used in this study as controls. The ability of melatonin and the APACHEII and BISAP scoring systems to predict SAP was evaluated using a receiver operating characteristic (ROC) curve. The optimal melatonin cutoff concentration for SAP patients, based on the ROC curve, was used to classify the patients into either a high concentration group (34 cases) or a low concentration group (21 cases). Differences in the incidence of high scores, according to the APACHEII and BISAP scoring systems, were compared between the two groups.RESULTS: The MAP patients had increased melatonin levels compared to the SAP (38.34 ng/L vs 26.77 ng/L) (P = 0.021) and control patients (38.34 ng/L vs 30.73 ng/L) (P = 0.003). There was no significant difference inmelatoninconcentrations between the SAP group and the control group. The accuracy of determining SAP based on the melatonin level, the APACHEII score and the BISAP score was 0.758, 0.872, and 0.906, respectively, according to the ROC curve. A melatonin concentration ≤ 28.74 ng/L was associated with an increased risk of developing SAP. The incidence of high scores (≥ 3) using the BISAP system was significantly higher in patients with low melatonin concentration (≤ 28.74 ng/L) compared to patients with high melatonin concentration (> 28.74 ng/L) (42.9% vs 14.7%, P = 0.02). The incidence of high APACHEII scores (≥ 10) between the two groups was not significantly different.CONCLUSION: The melatonin concentration is closely related to the severity of AP and the BISAP score. Therefore, we can evaluate the severity of disease by measuring the levels of serum melatonin.

Association between acute pancreatitis and peptic ulcer disease

AIM:To evaluate the relationship between peptic ulcer disease(PUD) and acute pancreatitis.METHODS:A cohort of 78 patients with acute pancreatitis were included in this study.The presence of PUD and the Helicobacter pylori(H.pylori) status were assessed by an endoscopic method.The severity of acute pancreatitis was assessed using Ranson's score,the Acute Physiology and Chronic Health Evaluation(APACHE) □ score,computed tomography severity indexand the clinical data during hospitalization,all of which were compared between the patients with and without PUD.The risk factors for PUD were also evaluated.RESULTS:Among 78 patients,41 patients(52.6%) with acute pancreatitis suffered from PUD,but only 13(31.7%) patients with PUD were infected by H.pylori.On univariate analysis,male gender,an etiology of alcohol-induced pancreatitis,a history of smoking or alcohol consumption,elevated triglyceride and C-reactive protein levels,and high APACHE □ score were signif icantly associated with PUD.However,on multivariate logistic regressionanalysis,the APACHE □ score(odds ratio:7.69;95% conf idence interval:1.78-33.33;P < 0.01) was found to be the only independent risk factor for PUD.CONCLUSION:Patients with acute pancreatitis are liable to suffer from PUD.PUD is associated with severeacute pancreatitis according to the APACHE □ score,and treatment for PUD should be considered for patients with severe acute pancreatitis.

Predictors of irreversible intestinal resection in patients with acute mesenteric venous thrombosis

BACKGROUND Acute mesenteric venous thrombosis(AMVT)can cause a poor prognosis.Prompt transcatheter thrombolysis(TT)can achieve early mesenteric revascularization.However,irreversible intestinal ischemia still occurs and the mechanism is still unclear.AIM To evaluate the clinical outcomes of and to identify predictive factors for irreversible intestinal ischemia requiring surgical resection in AMVT patients treated by TT.METHODS The records of consecutive patients with AMVT treated by TT from January 2010 to October 2017 were retrospectively analyzed.We compared patients who required resection of irreversible intestinal ischemia to patients who did not require.RESULTS Among 58 patients,prompt TT was carried out 28.5 h after admission.A total of 42(72.4%)patients underwent arteriovenous combined thrombolysis,and 16(27.6%)underwent arterial thrombolysis alone.The overall 30-d mortality rate was 8.6%.Irreversible intestinal ischemia was indicated in 32(55.2%)patients,who had a higher 30-d mortality and a longer in-hospital stay than patients without resection.The significant independent predictors of irreversible intestinal ischemia were Acute Physiology and Chronic Health Evaluation(APACHE)II score(odds ratio=2.368,95% confidence interval:1.047-5.357,P=0.038)and leukocytosis(odds ratio=2.058,95% confidence interval:1.085-3.903,P=0.027).Using the receiver operating characteristic curve,the cutoff values of the APACHE II score and leukocytosis for predicting the onset of irreversible intestinal ischemia were calculated to be 8.5 and 12×10^9/L,respectively.CONCLUSION Prompt TT could achieve a favorable outcome in AMVT patients.High APACHE II score and leukocytosis can significantly predict the occurrence of irreversible intestinal ischemia.Therefore,close monitoring of these factors may help with the early identification of patients with irreversible intestinal ischemia,in whom ultimately surgical resection is required,before the initiation of TT.

Different phenotypes of monocytes in patients with newonset mild acute pancreatitis

AIM To evaluate the numbers of different subsets of monocytes and their associations with the values of clinical measures in mild acute pancreatitis(MAP) patients.METHODS The study included one group of 13 healthy controls and another group of 24 patients with new-onset MAP. The numbers of different subsets of monocytes were examined in these two groups of subjects by flow cytometry. The concentrations of plasma interleukin(IL)-10 and IL-12 were determined by cytometric bead array. The acute physiology and chronic health evaluation(APACHE) II scores of individual patients were evaluated, and the levels of plasma C-reactive protein(CRP) as well as the activities of amylase and lipase were measured. RESULTS In comparison with that in the controls, significantly increased numbers of CD14+CD163-, CD14+CD163-MAC387+ M1 monocytes, but significantly reduced numbers of CD14+CD163+IL-10+ M2 monocytes were detected in the MAP patients(P < 0.01 or P < 0.05). Furthermore, significantly higher levels of plasma IL-10 and IL-12 were observed in the MAP patients(P < 0.01 for all). More importantly, the levels of plasma CRP were positively correlated with the numbers of CD14+CD163-(R = 0.5009, P = 0.0127) and CD14+CD163-MAC387+(R = 0.5079, P = 0.0113) M1 monocytes and CD14+CD163+CD115+ M2 monocytes(R = 0.4565, P = 0.0249) in the patients. The APACHE II scores correlated with the numbers of CD14+CD163+CD115+(R = 0.4581, P = 0.0244) monocytes and the levels of plasma IL-10(R = 0.4178, P = 0.0422) in the MAP patients. However, there was no significant association among other measures tested in this population. CONCLUSION Increased numbers of CD14+CD163- and CD14+ CD163-MAC387+ monocytes may contribute to the pathogenesis of MAP, and increased numbers of CD14+CD163+CD115+ monocytes may be a biomarker for evaluating the severity of MAP.

目的 探讨中性粒细胞与淋巴细胞比值(NLR)结合红细胞分布宽度(RDW)对急诊老年脓毒症病人疾病严重程度和预后的评估意义。方法 收集2019年1月到2022年2月在首都医科大学宣武医院急诊科就诊及住院治疗的老年脓毒症病人169例。病人入急诊后给予生化全项、血气分析、全血细胞计数、降钙素原(PCT)、胸部计算机体层摄影(CT)、病原学检查等。依据以上检查结果进行急性生理与慢性健康状况评估(APACHEⅡ)。根据病人入急诊时合并脓毒性休克情况分为脓毒症组114例和脓毒性休克组55例。随访28 d,依据病人死亡情况分成生存组125例和死亡组44例。分别比较脓毒性休克组和脓毒症组、生存组和死亡组病人NLR、白细胞计数(WBC)、PCT、RDW和APACHEⅡ评分的区别,进行NLR、RDW与PCT及APACHEⅡ评分的相关性分析;分析RDW、NLR及2个指标相互结合评估老年脓毒症病人死亡风险的受试者工作特征曲线下面积(AUC)和PCT曲线下面积的区别。结果 脓毒症休克组病人PCT、NLR、RDW和APACHEⅡ评分分别为(1.86±1.04)μg/L、9.63±3.92、(14.95±3.49)%和(16.75±3.53)分,均明显高于脓毒症组的(1.38±1.06)μg/L、7.87±3.94、(12.74±3.83)%、(14.61±2.87)分(P<0.01);WBC在脓毒症死亡组与生存组比较差异无统计学意义(P=0.361),死亡组APACHEⅡ评分、NLR、PCT和RDW分别为(18.52±2.41)分、(10.64±3.74)、(2.55±1.14)μg/L和(15.98±3.69)%,均大于生存组的(14.17±2.71)分、7.67±3.82、(1.19±0.81)μg/L、(12.57±3.43)%(P<0.01),RDW和NLR均与APACHEⅡ评分和PCT具有相关性(均P<0.01);PCT的AUC 95%CI为0.86(0.80,0.92),APACHEⅡ评分的AUC 95%CI为0.88(0.83,0.93),RDW的AUC 95%CI为0.75(0.66,0.83),NLR的AUC95%CI为0.73(0.64,0.81),RDW和NLR的AUC均小于PCT(P=0.048,0.024),但RDW与NLR联合的AUC为0.80,与PCT比较差异无统计学意义(P=0.363)。结论 NLR及RDW两个指标都能够在急诊老年脓毒症病人的病情和预后评估中有较好的应用价值,二者联合的应用价值与PCT相近。

急诊危重病患者血清硫化氢浓度与APACHEⅢ评分及预后关系的研究

目的探讨急诊监护室(EICU)危重病患者血清硫化氢(H2S)浓度改变与急性生理学及慢性健康状况评分Ⅲ(APACHEⅢ)及预后的关系。方法采用分光光度法检测72例入住EICU的危重病患者及12例健康体检者的血清H2S浓度,并对危重病患者进行APACHEⅢ评分;分析血清H2S浓度与APACHEⅢ评分及死亡率的关系。结果72例患者血清H2S浓度为(45.6±17.2)μmol/L,存活组血清H2S浓度(41.1±14.7)μmol/L,死亡组血清H2S浓度(62.8±15.5)μmol/L,两组比较差异有统计学意义(P<0.01);72例患者APACHEⅢ评分(43.6±26.0)分,存活组APACHEⅢ评分(37.7±22.2)分,死亡组APACHEⅢ评分(65.0±29.6)分,两组比较差异有统计学意义(P<0.01)。血清H2S浓度与APACHEⅢ评分呈正相关(r=0.7422,P<0.01),随各组血清H2S浓度增高,APACHEⅢ评分值亦增高(F=33.69,P<0.001),各组死亡率也随之增高(χ2=24.48,P<0.01)。结论急诊危重病患者血清H2S浓度较健康者明显增高,对判断病情及预后有一定的作用。
