Methods : Twentyfour SAP patients who admitted to hospital within 72h after onset were randomized into treatment group (n=12) and control group (n=12). The patients in the treatment group were treated by Yihuo Qingxia method, and the control group were administrated with placebo.The level of the serum mcp1 of the patients on the first,3rd,5th,7thday were measured, as well as the incidence and the duration of disfunction of the organs were compared.〖WTHZ〗Results :There were no statistical significance in admission Rason scores, CT scores, Acute physiology and chronic health evaltionⅡscores(APACHEⅡscores)(Pgt;005). The level of the serum Monocyte chemoattractant protein1 of the treatment group was lower than that of the placebo group generally(Plt;005).At the 3rd day after onset,the serum mcp1 level of the control group was significantly higher than that of the treament group(Plt;005).The incidence of the control group of the intestin disfunction and hepatic inadequacy was obviously higher than those of the treatment group,and the duration of the former was longer than that of the latter,but with no satistical significance. Conclusion :Yihuo Qingxia method can effectively cut down the level of the serum mcp1 of severe pancreatitis patients.
ObjectiveTo investigate predictive value of a new blood biochemical scoring system (CPWAG scoring system) on severity and mortality of acute pancreatitis (AP).MethodsThe AP patients who met the inclusion and exclusion criteria in our hospital from January 2017 to June 2019 were collected, then were divided into severe acute pancreatitis (SAP) group and non-SAP group according to the latest Atlanta classification. The differences of clinical characteristics and related blood biochemical indicators between the SAP group and the non-SAP group were compared. Univariate logistic regression analysis was used to screen blood biochemical risk indicators related to SAP. The receiver operating characteristic (ROC) curve was used to obtain the best cut-off value corresponding to the maximum Youden index of statistical significant risk factors and was assigned as 0 or 1 point according to different situations. At the same time, the pleural effusion of the BISAP score was included and assigned as 0 (yes) or 1 (no) point, then the CPWAG score was obtained by adding the point of the above indexes.The areas under the ROC curve (AUC) of the CPWAG, BISAP, APACHEⅡ, CTSI, and Ranson scoring systems in predicting severity and death of AP patients were also compared.ResultsA total of 451 patients with AP were included in this study, including 85 patients with SAP and 366 patients with non-SAP. Compared with the non-SAP group, the etiology of AP was mainly biliary (P<0.05), with higher levels of white blood cell count (WBC), C reactive protein (CRP), procalcitonin (PCT), and glucose (P<0.05), greater red blood cell distribution width value (P<0.05), longer prothrombin time (PT) and hospital stay (P<0.05), lower albumin (ALB) and blood calcium levels (P<0.05), higher BISAP, APACHEⅡ, CTSI and Ranson points (P<0.05), and higher proportions of patients with pleural effusion, multiple organ dysfunction syndrome, and death (P<0.05) in the SAP group. The highest score of the CPWAG scoring system included CRP, PCT, WBC, ALB, glucose, blood calcium, and pleural effusion was 7. With the increase of CPWAG score, the proportion of SAP and death patients showed an increasing trend (P<0.001). The AUC of the CPWAG scoring system in predicting SAP was 0.866, which was higher than those of Ranson (AUC=0.722, Z=5.317, P<0.001), APACHEⅡ (AUC=0.706, Z=5.019, P<0.001), and CTSI (AUC=0.805, Z=1.962, P=0.005) scoring system, but which had no statistically significant difference as compared with the BISAP scoring system (AUC=0.819, Z=1.816, P=0.070). The AUC of the CPWAG scoring system in predicting death had a high ability (AUC=0.823), which had no significant differences as compared with the Ranson, APACHEⅡ, CTSI, and BISAP scoring systems (P>0.05).ConclusionThe CPWAG score is valuable in predicting the severity and mortality of AP patients, allowing accurate and early assessment of AP patients.
【Abstract】Objective To investigate a more rational modality which is in the treatment of severe acute pancreatitis (SAP) and effective in preventing liver from damages due to SAP. Methods SAP model was established by retrograde injection of 5% sodium taurocholate (1.0 ml) in the subserosa of pancreas in rats (n=80) weighting 200-250 g.The rats were catheterized using PE-50 angiocatheter from femoral artery to celiac trunk. Then they were randomly divided into four groups. Twenty animals served as controls (A group) and received only fluid infusion. The 40 animals, B and C group (20 animals in each one group) received continuous regional arterial infusion (CRAI) of somatostatin （4 μɡ/kg） and the medicines improving microcirculatory (dextran-40 1.5 ml, dopamine hydrochloride 5 μg/kg, anisodaminum 1.5 ml/kg) respectively. The other 20 animals (D group) were treated by somatostatin combined with the medicine improving microcirculatory through CRAI simultaneously with the induction of pancreatitis. The AST, ALT, ALP and serum amylase were recorded, the liver and pancreas tissue were observed pathologicaly after 6 hours. Results There were a ignificant decrease in the serum amylase in B group (Plt;0.05) and D group (Plt;0.05). The AST, ALT, ALP was decreased in B and D group (Plt;0.05). The damage to liver and pancreas were reduced in D group. Conclusion CRAI is effective in preventing liver damages due to SAP and is an effective way in the treatment of SAP.
【Abstract】Objective To study the influence of early hemofiltration on plasma concentrations of proinflammatory cytokines TNF-α and IL-1β and their transcription levels in severe acute pancreatitis (SAP) pigs. Methods The model of SAP was induced by retrograde injection of artificial bile into pancreatic duct in pigs. Animals were divided randomly into two groups: SAP hemofiltration treatment group (HF group, n=8) and SAP no hemofiltration treatment group (NHF group, n=8). TNF-α and IL-1β plasma concentrations were measured by ELISA. Their transcription levels in the tissues of pancreas, liver and lung were assayed by semi-quantitative reverse transcription polymerase chain reaction. Results After hemofiltration treatment, the plasma concentrations of TNF-α and IL-1β increased gradually but were lower than those of NHF group at the same time spot 〔at 6 h after hemofiltration treatment, (618±276) pg/ml vs (1 375±334) pg/ml and (445±141) pg/ml vs (965±265) pg/ml, P＜0.01〕. At 6 h after hemofiltration treatment, the transcription levels of TNF-α and IL-1β in tissues of pancreas, liver and lung were lower than in NHF group (57.8±8.9 vs 85.7±17.4, 48.0±8.1 vs 78.1±10.2, 46.2±9.6 vs 82.4±10.5; 55.9±9.0 vs 82.2±15.7, 40.6±9.2 vs 60.0±10.6, 35.7±9.8 vs 58.1±9.3, P＜0.01). Conclusion Early hemofiltration can reduce TNF-α and IL-1β plasma concentrations and transcription levels in SAP pigs.
Objective To investigate the mechanism of radix salviae miltiorrhizae (RSM) injection in treatment of pancreatitis through observing the changes of activity of nuclear factor-kappa B (NF-κB) in pancreas of rats with severe acute pancreatitis (SAP) and the influence of RSM injection upon NF-κB in pancreas tissue. Methods Seventy-five rats were randomly divided into 3 groups: normal control group, SAP group and RSM treatment group, which were injected with normal saline, normal saline or RSM in the peritoneal cavity, respectively. The model of SAP rats was made by injecting L-arginine into peritoneal cavity and by subcutaneous injection at the same time. The concentrations of amylase in plasma and in ascites were measured respectively, and the expression of NF-κB in pancreas tissues was determined by immunohistochemistry. Results The levels of amylase in plasm and ascites in SAP group and RSM treatment group increased significantly with the increased expression of NF-κB in pancreas tissue, but it was also found that both the level of amylase and the expression of NF-κB in RSM treatment group were significantly lower compared with those in SAP group, and the survival time of RSM treatment group was longer than SAP group with less pathological injury in the pancreas tissues. Conclusion RSM may be effective for the treatment of pancreatitis by degrading the expression of NF-κB.
ObjectiveTo explore the relationship between blood glucose variability index and persistent organ failure (POF) in acute pancreatitis (AP). MethodsWe prospectively included those patients who were diagnosed with AP with hyperglycemia and were hospitalized in the West China Center of Excellence for Pancreatitis of West China Hospital of Sichuan University from July 2019 to November 2021. The patients were given blood glucose monitoring at least 4 times a day for at least 3 consecutive days. The predictive value of blood glucose variability index for POF in patients with AP was analyzed. ResultsA total of 559 patients with AP were included, including 95 cases of POF. Comparing with those without POF, patients with AP complicated by POF had higher levels of admission glucose (11.0 mmol/L vs. 9.6 mmol/L), minimum blood glucose (6.8 mmol/L vs. 5.8 mmol/L), mean blood glucose (9.6 mmol/L vs. 8.7 mmol/L), and lower level of coefficient of variation of blood glucose (16.6 % vs. 19.0 %), P<0.05. Logistic regression analyses after adjustment for confounding factors showed that the risk of POF increased with the increase of admission glucose [OR=1.11, 95%CI (1.04, 1.19), P=0.002], minimum blood glucose [OR=1.28, 95%CI (1.10, 1.48), P=0.001] and mean blood glucose [OR=1.18, 95%CI (1.04, 1.33), P=0.010]; with the higher level of coefficient of variation of blood glucose [OR=0.95, 95%CI (0.92, 0.99), P=0.021], the risk of POF decreased. The results of area under the curve (AUC) of the receiver operator curves showed that AG [AUC=0.787, 95%CI (0.735, 0.840)] had the highest accuracy in predicting POF, with sensitivities of 60.0% and specificities of 84.7%. ConclusionHigh admission glucose, minimum blood glucose, mean blood glucose, and low coefficient of variation of blood glucose were risk factors for the development of POF in patients with hyperglycemic AP on admission.
To evaluate the role of octreotide in the treatment of severe acute pancreatitis (SAP). Seventy-six patients were divided into two groups (octreotide group, n＝38, control group, n＝38). All patients were treated by the same conservative regime. The octreotide group received octreotide. Results: The abdominal symptoms and signs, WBC count, serum amylase level, and volume of ascites were more effective controlled, with fewer complications occurred in octreotide group. Conclusion: Octreotide has a beneficial effect on the treatment of SAP, but the mechanism will be further investigated.
ObjectiveTo investigate correlation of bedside index for severity in acute pancreatitis (BISAP) and computed tomography severity index (CTSI) or modified CT severity index (MCTSI) in assessing severe acute pancreatitis (SAP). MethodsThirty-eight patients confirmed SAP from July 2015 to October 2015 in West China Hospital of Sichuan University were prospectively included into this study. Contrast-enhanced multi-detector-row CT scan was performed for all the patients. The abnormal imaging features, such as pancreatic and peri-pancreatic inflammatory changes, involvement of other organs, and local complications, were observed and used to calculate by CTSI score and MCTSI score. The clinical data were also collected to calculate BISAP score and as compared with CTSI score and MCTSI score. ResultsThe results of BISAP score were as follows:3 cases gradeⅠ(8.9%), 20 cases gradeⅡ(52.6%), 15 cases gradeⅢ(39.5%). The results of CTSI score were as follows:6 cases gradeⅠ(15.8%), 22 cases gradeⅡ(57.9%), 10 cases gradeⅢ(26.3%). The results of MCTSI score were as follows:2 cases gradeⅠ(5.3%), 19 cases gradeⅡ(50.0%), 17 cases gradeⅢ(44.7%). The results of interobserver agreement were good (BISAP:Kappa=1, P < 0.01; CTSI:Kappa=0.748, 95% CI 0.00-0.076, P < 0.01; MCTSI:Kappa=0.788, 95% CI 0.00-0.076, P < 0.01). There was a positive correlation between CTSI score (rs=0.385, P=0.001) or MCTSI score (rs=0.326, P=0.004) and BISAP score using the Spearman test. ConclusionThere is a weak correlation between CTSI score or MCTSI score and BISAP score.
Severe acute pancreatitis (SAP) is a serious acute inflammatory disease with complex pathogenesis, rapid progression, high mortality, extensive treatment, and heavy socioeconomic burden, which is often complicated by systemic multiple organ dysfunction. Renal replacement therapy (RRT) is essential for removing inflammatory mediators, cytokines or other toxins, as well as stabilizing the internal environment. Therefore, RRT is utilized as an organ support technology in the clinical management of SAP. Currently, there is no consensus regarding when and under what circumstances RRT can be employed in patients with SAP. In this paper, the pathogenesis of SAP and the indications and timing of initiation of RRT will be discussed.
ObjectiveTo systematically review the efficacy and safety of early abdominal paracentesis drainage (APD) in patients with severe acute pancreatitis (SAP). MethodsThe PubMed, Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were searched to collect randomized controlled trials and cohort studies on the management of SAP via early APD from inception to December 10, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software and Stata 17.0 software. ResultsEighteen studies were included, with a total sample size of 2 685 patients. The meta-analysis showed that early APD could decrease mortality (OR=0.49, 95%CI 0.35 to 0.69, P<0.01) and the incidences of multiple organ failure (OR=0.56, 95%CI 0.45 to 0.71, P<0.01), ARDS (OR=0.54, 95%CI 0.41 to 0.71, P<0.01), and infectious complications (OR=0.72, 95%CI 0.57 to 0.92, P<0.01) and also reduce the need for further interventions and the total cost incurred during hospitalization, reduce the length of hospital stay, and reduce the number of days spent in the intensive care unit. However, there were no significant differences in the incidence of pneumonia, bacteremia, and sepsis between the two groups. ConclusionThe treatment of SAP via early APD, which has high clinical value, could decrease the incidence of multiple organ failure, improve the prognosis of patients, and reduce the associated mortality rate. Moreover, APD does not increase the risk of infection-related complications. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
