Network Pharmacology Analysis and Retrospective Cohort Study Revealing the Effect of Qingyi Decoction on Intestinal Paralysis in Patients with Severe Acute Pancreatitis.

Intestinal dysfunction plays an important role in the clinical progress and prognosis of severe acute pancreatitis (SAP). Qingyi decoction (QYD) has shown beneficial effects on intestinal function recovery, but the prevention actions of the QYD on intestinal paralysis and its mechanism have not been fully explored. The possible molecular mechanism was unraveled by network pharmacology, including active ingredients and potential target prediction, as well as GO, KEGG, and REATCOME pathway enrichment analyses. The potential interactions between the main active ingredients of the QYD and core genes were explored by molecular docking. A retrospective cohort study on 137 patients with SAP from Tianjin Nankai Hospital was conducted to evaluate the preventive effect of QYD on intestinal paralysis. A total of 110 active ingredients in QYD were screened out, and 37 key targets were predicted by network pharmacology. GO, KEGG, and REATCOME enrichment analyses showed that bioinformatics annotation of the hub genes was mainly involved in intestinal epithelial functions and inflammatory response pathways. The main components of QYD possessed good affinity with IL-6, TNF, CASP3, CXCL8, and CRP by molecular docking. Patients who used QYD plus usual care seemed to have fewer intestinal paralysis rates, lower risk of renal insufficiency, ARDS and blood purification therapy, and shorter hospital and ICU stays. The multivariable regression analyses indicated that the mode of nasogastric and enemas administration of QYD (P = 0.010) and timely intervention with QYD (P = 0.045) were the independent protective factors for intestinal paralysis prevention in patients with SAP. In conclusion, QYD can be used as an effective adjuvant procedure to prevent the occurrence and development of intestinal paralysis in patients with SAP. The mechanisms may be involved in the anti-inflammatory response and maintenance of intestinal epithelial function.

Analysis of factors influencing onset and survival of patients with severe acute pancreatitis: Aclinical study.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas, and the prognosis of severe AP (SAP) is poor. The study aimed to identify promising biomarkers for predicting the occurrence and survival outcome of SAP patients. Two hundred and fortyAP patients were retrospectively recruited, in which 72 cases with SAP. Blood test was done for collection of laboratory indicators. After treatment, the mortality of patients was recorded. Patients in the SAP group had higher intensive care unit admissions and longer hospital stays (p < .001). Among laboratory parameters, significantly high values of C-reactive protein (CRP),triglycerides and glucose (TyG) index, Von willebrand factor antigen (vWF:Ag) and D-dimer were found in SAP groups relative to non-SAP ones. Receiver operating characteristiccurve indicated the good performance of CRP, TyG index, vWF:Ag and D-dimer in SAP diagnosis. Among all SAP cases, 51 survived while 21 died. TyG index (odds ratio [OR] = 6.914, 95% confidence interval [CI] = 1.193-40.068, p = .028), vWF:Ag (OR = 7.441, 95%CI = 1.236-244.815, p = .028), and D-dimer (OR = 7.987, 95%CI = 1.251-50.997, p = .028) were significantly related to survival outcome of SAP patients by multiple logistic regression analysis. Both TyG index and vWF showed favorable efficiency in predicting overall prognosis. The area under the curve for the multivariate model (PRE = -35.908 + 2.764 × TyG + 0.021 × vWF:Ag) was 0.909 which was greater than 0.9, indicating its excellent performance in prognosis prediction. CRP, TyG index, vWF:Ag, and D-dimer values on admission may be potential clinical predictors of the development of SAP. Moreover, TyG index and vWF:Ag may be helpful to predict survival outcome.

The impact of skeletal muscle index at the third lumbar spine on nosocomial deterioration and short-term prognosis in acute pancreatitis: a retrospective observational study.

To investigate the impact of the third lumbar skeletal muscle index (L3-SMI) assessed by CT on the in-hospital severity and short-term prognosis of acute pancreatitis. A total of 224 patients with severe acute pancreatitis admitted to Yantaishan Hospital from January 2021 to June 2022 were selected as the subjects. Based on the in-hospital treatment outcomes, they were divided into a mortality group of 59 cases as well as a survival group of 165 cases. Upon admission, general information such as the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, along with the abdominal CT images of each patient, were analyzed. The L3-SMI was calculated, and the Modified CT Severity Index (MCTSI) and Balthazar CT grade were used to assess the severity of in-hospital complications of acute pancreatitis. The evaluation value of L3-SMI for the prognosis of severe acute pancreatitis was analyzed, as well as the factors influencing the prognosis of severe acute pancreatitis. No statistically significant differences in gender, age, BMI, etiology, duration of anti-inflammatory drug use, and proportion of surgical patients between the survival and mortality groups were observed. But the mortality group showed higher proportions of patients with an elevated APACHE II score upon admission, mechanical ventilation, and renal replacement therapy, compared to the survival group, with statistically significant differences (P < 0.001). Furthermore, the mortality group had higher MCTSI scores (6.42 ± 0.69) and Balthazar CT grades (3.78 ± 0.45) than the survival group, with statistically significant differences (P < 0.001). The mortality group also had a lower L3-SMI (39.68 ± 3.25) compared to the survival group (42.71 ± 4.28), with statistically significant differences (P < 0.001). L3-SMI exhibited a negative correlation with MCTSI scores and Balthazar CT grades (r = -0.889, -0.790, P < 0.001). Logistic regression analysis, with mortality of acute pancreatitis patients as the dependent variable and MCTSI scores, Balthazar CT grades, L3-SMI, APACHE II score upon admission, mechanical ventilation, and renal replacement therapy as independent variables, revealed that MCTSI scores and L3-SMI were risk factors for mortality in acute pancreatitis patients (P < 0.001). Logistic regression analysis using the same variables confirmed that all these factors were risk factors for mortality in acute pancreatitis patients. This study confirmed that diagnosing muscle depletion using L3-SMI is a valuable radiological parameter for predicting in-hospital severity and short-term prognosis in patients with acute pancreatitis.

Effect of vitamin D binding protein gene polymorphism on susceptibility and prognosis of severe acute pancreatitis

To investigate the effect of vitamin D binding protein (DBP) gene polymorphism on susceptibility and prognosis of severe acute pancreatitis (SAP). A prospective study was conducted. Eighty-three patients with SAP who were admitted to the department of general surgery of Tianjin Fifth Central Hospital from March 2018 to March 2021 were selected as the research objects, and 83 healthy people in the same period were selected as controls. Peripheral blood RNA was extracted and reverse transcribed into cDNA, and the genotype and allele frequency of DBP gene rs7041 locus were detected by fluorescence quantitative analyzer. Hardy-Weinberg equilibrium was used to test the genetic balance. On the day of admission, serum C-reactive protein (CRP) level was detected by scattering immunoturbidimetry, serum procalcitonin (PCT) level was detected by electrochemiluminescence, serum DBP level was detected by enzyme-linked immunosorbent assay (ELISA), and neutrophil to lymphocyte ratio (NLR) was calculated automatically by the instrument. The length of intensive care unit (ICU) stay, the length of hospital stay and prognosis during hospitalization of patients were statistically analyzed. Multivariate Logistic regression analysis was used to screen the influencing factors of SAP occurrence. The results of Hardy-Weinberg equilibrium test showed that the distribution of gene polymorphisms in the two groups of subjects conformed to the law of genetic equilibrium. The frequencies of TT genotype and T allele of DBP gene rs7041 locus in the patients of SAP group were significantly higher than those in the healthy control group [TT genotype: 34.94% (29/83) vs. 9.64% (8/83), T allele: 55.42% (92/166) vs. 38.55% (64/166), both P < 0.01], and the frequency of GT genotype was significantly lower than that in the healthy control group [40.96% (34/83) vs. 57.83% (48/83), P < 0.05]. There was no significant difference in the frequency of GG genotype between the healthy control group and SAP group [32.53% (27/83) vs. 24.10% (20/83), P > 0.05]. Further multivariate Logistic regression analysis showed that TT genotype [odds ratio (OR) = 2.831, 95% confidence interval (95%CI) was 1.582-5.067, P < 0.001] and T allele (OR = 2.533, 95%CI was 1.435-4.472, P < 0.001) of DBP gene rs7041 locus were independent risk factors for SAP in healthy people, while GT genotype was a protective factor for SAP (OR = 0.353, 95%CI was 0.143-0.868, P = 0.041). The levels of CRP, PCT, NLR and DBP in patients with TT genotype of DBP gene rs7041 locus were significantly higher than those in patients with GG/GT genotype on the day of admission in SAP group [CRP (mg/L): 43.25±13.25 vs. 31.86±12.83, PCT (μg/L): 1.53±0.24 vs. 1.21±0.20, NLR: 3.15±0.53 vs. 2.71±0.48, DBP (μg/L): 87.78±19.64 vs. 70.58±18.67, all P < 0.01]. The length of ICU stay in patients with TT genotype of DBP gene rs7041 locus in SAP group was significantly longer than that in patients with GG/GT genotype (days: 11.35±1.58 vs. 9.71±1.35, P < 0.01). The length of hospital stay of patients with TT genotype was longer than that of patients with GG/GT genotype (days: 23.41±3.64 vs. 23.17±3.57), and the in-hospital mortality was higher than that of patients with GG/GT genotype [34.48% (10/29) vs. 29.63% (16/54)], but the difference was not statistically significant (both P > 0.05). The risk of SAP was significantly increased in patients with TT genotype of rs7041 locus of DBP gene, and the mechanism may be related to the increase of DBP expression. And carrying the TT genotype will prolong the ICU hospitalization time of SAP patients, but the effect on prognosis is not obvious.

Association between albumin or prealbumin levels at different stages and prognosis in severe acute pancreatitis: a 5-year retrospective study

Severe acute pancreatitis (SAP) is a common abdominal disorder contributing to high mortality and open laparotomy rates. The role of exogenous infused albumin in fluid resuscitation or continuous therapy has always been an unanswered question. In early stage after onset, SAP patients with higher serum albumin or prealbumin show a better prognosis. In this study, we tried to disclose the linkage between albumin/prealbumin and SAP prognosis and establish a new goal-directed therapy involving albumin and prealbumin. Pearson’s chi-squared test and the Mann–Whitney U test were used to compare the descriptive data between surviving and non-surviving patients. Three days, 4–7 days, 8–14 days and 15–28 days after SAP onset were defined as stages 1–4. The average concentrations of albumin and prealbumin were calculated, and receiver operating characteristic (ROC) curves were drawn to screen out the best cutoff values associated with poor prognostic outcomes, including laparotomy and failure to survive. Kaplan–Meier survival curves and log-rank tests were used to validate the effect of the cut-off values. A total of 199 admitted patients were enrolled in this study. According to the analysis of the ROC curve, the serum albumin value should be raised to 35, 37, 40 and 42 g/L in the 1–4 stage after onset. Serum prealbumin values should be raised to 108, 180, and 181 g/L in stages 2–4 after onset. The validity of the above data was confirmed by Kaplan–Meier survival curves. Serum albumin and prealbumin levels in the early stage of SAP are significantly relevant to prognosis. Albumin should be infused from the fluid resuscitation stage to continuous therapy in order to reach the targets mentioned above. The increase in prealbumin depends on the early initiation of enteral nutrition and this also helps to ameliorate the prognosis.

Elevated serum ferritin levels are associated with severity and prognosis of severe acute pancreatitis: a preliminary cohort study

BackgroundSerum ferritin (SF), as an acute-phase response protein, is used to reflect the degree of oxidative stress and systemic inflammatory responses. This study was designed to assess the effect of elevated SF levels on the severity of acute pancreatitis (AP).MethodsFrom January 2013 to December 2020, 200 consecutive patients with AP were retrospectively reviewed to analyze the relationships among the etiologies of pancreatitis, the severity of the disease and SF levels. The receiver operating characteristic (ROC) curve and logistic regression analysis were used to assess whether elevated SF levels could predict the onset of organ failure in AP.Results92 (46%) had high SF levels (> 275 ng/ml). SF levels were not associated with the etiology of AP disease. Among patients with high SF levels, there was a significant increase in the proportion of patients with severe AP (23.1% vs. 76.9%) and a higher proportion of systemic inflammatory response scores (25.9% vs. 44.6%) in comparison to patients with normal SF levels. The area under the ROC curve for SF in predicting persistent organ failure was 0.812 [95% confidence interval 0.721–0.904].ConclusionsF concentrations were positively correlated with the severity of AP, and quantitative assessment of SF can predict disease severity and organ failure in patients with AP.

DIA-Based Proteomic Analysis of Plasma Protein Profiles in Patients with Severe Acute Pancreatitis

Acute pancreatitis (AP) is a pancreatic inflammatory disease that varies greatly in course and severity. To further the understanding of the pathology of AP, we carried out data-independent acquisition-based proteomic analyses using proteins extracted from the plasma of patients with severe acute pancreatitis (SAP) (experimental group) and healthy volunteers (control group). Compared to the control group, there were 35 differentially expressed proteins (DEPs) in the plasma of patients with SAP. Of those, the expression levels for 6 proteins were significantly increased, and 29 proteins were significantly decreased. Moreover, six candidate biomarkers—VWF, ORM2, CD5L, CAT, IGLV3-10, and LTF—were matched as candidate biomarkers of the disease severity of AP. The area under the receiver operating characteristic of 0.903 (95% CI: 0.839, 0.967) indicated that this combination of these six candidate biomarkers had a good prediction accuracy for predicting the severity of AP. Our study provides specific DEPs that may be useful in the diagnosis and prognosis of SAP, which suggests new theoretical bases for the occurrence and development of SAP and offers potential novel treatment strategies for SAP.

Intra-abdominal Pressure as a Prognostic Factor in Severe Acute Pancreatitis

Abstract Objective:To assess the prognostic value of Intra-abdominal Pressure in severe acute pancreatitis, compare it to APACHE II, to determine when to intervene based on intra abdominal pressure. Materials and Methods:We studied the role of intra-abdominal pressure measurement as a prognostic index and its applicability to determine the timing of intervention in cases of severe acute pancreatitis as a prospective cohort study from 2010- 2012, at Kamineni Hospital, L.B Nagar, Hyderabad. All patients who were admitted with severe acute pancreatitis and consented to take part in the study were enrolled. All patients were evaluated clinically, radiologically, biochemically and by the prognostic indices – APACHE II, Ranson criteria and intra-abdominal pressure measurement. A total of 55 patients were enrolled in this study. Intra-abdominal pressure was measured by intravesical technique using a Foley catheter.Intra-abdominal pressure was measured every 12 hours. Within 24 hours of admission, APACHE II score was obtained. Multivariate analysis was utilised for statistics. Results:Males comprised 73% of study population. Mean age was 41.23± 13.74 years (17- 83 years). Ten patients (18.81%) died. Among the non-survivors, the intra-abdominal pressure (20.1± 3.1073 Vs 8.97± 4.39) and the APACHE II (17.5 ±4.09 Vs3.93 ±4.345),were significantly greater, P value &lt;0.0001. The AUC for intra-abdominal pressureat 24 hours and at 72 hours was &gt;0.7, which is highly significant. The sensitivity for intra-abdominal pressure(&gt;13 mm Hg) at 72 hours as a marker for mortality was 100%. Conclusion:The Intra-abdominal pressure monitoring is rapid, reproducible, inexpensive and minimally invasive, and can be used as a marker of the severity and prognosis of severe acute pancreatitis. Intra-abdominal pressure could potentially be used to guide the timing of intervention. Compared to APACHE II, which is inclusive of multiple parameters, intra-abdominal pressure can serve the same purpose as a single prognostic index. Further, we recommend a large, multicentric studies to conclusively establish the predictive power of intra-abdominal pressure in acute pancreatitis and whether interventions known to reduce intra-abdominal pressure, can alter the ultimate outcome.

Effects of Indwelling Pleural Catheter on Severe Acute Pancreatitis: A Retrospective Study.

Background Pleural effusion (PE) is an important predictor for severity and prognosis of severe acute pancreatitis (SAP). However, there are few studies focused on the effects and timing of indwelling pleural catheter (IPC) on SAP. Considering this, we designed a retrospective study to verify the relationship between PE and severity of SAP and observe the effects and timing of IPC in SAP. Methods A total of 309 SAP patients were enrolled. Based on the presence or absence of PE and IPC and IPC time, the enrolled patients were divided into 6 groups. Then, baseline parameters, disease severity, critical complications, ventilator supporting time (VST), length of stay (LOS), and 60-day mortality were compared between each two groups. Results PE was a risk factor for death of SAP, but not an independent risk factor. SAP patients with PE rather without PE had higher critical complication rates (p < 0.001), along with longer VST (p < 0.001) and LOS (p < 0.001). And the critical complication rates were lower in group 1 (IPC within 1 week of onset) than group 2 (IPC after 1 week of onset). Further, patients in group 1 also had shorter LOS (p = 0.042) and VST (p = 0.001) than those in group 2. In addition, the survival analysis showed the risk of death in the PE group was higher than the non-PE group (HR 6.6, 95% CI, 3.67–11.86, and p < 0.001). And the risk of death in group 1 was lower than group 2 (HR 0.26, 95% CI, 0.08–0.84, and p = 0.025). Conclusions PE is a risk factor for death of SAP, but not an independent risk factor. IPC, especially IPC within 1 week of onset, has clinical practical value in SAP.

Luzhou-Feier powder reduces inflammatory response and improves intestinal immune barrier in rats with severe acute pancreatitis.

As we know, nutritional support plays a key role in the treatment of severe acute pancreatitis (SAP). Since total parenteral nutrition (TPN) was discovered, the mortality of SAP had been greatly reduced. But researchers recently demonstrated that the prognosis of SAP could be improved by early enteral nutrition (EEN), which has been a priority for nutritional support in patients with SAP. However, implementation of total enteral nutrition is often challenging in the early stage of SAP. If the enteral nutrition is overused, the burden on the gastrointestinal tract will be aggravated. Under such circumstances, the combination of enteral and parenteral nutrition for nutritional support of SAP patients would be a better choice. Therefore, in this study, we compared the efficacy of two enteral nutrition agents: traditional nutritional supplement named Luzhou-Feier powder (LZ-FP) and enteral nutritional suspension (TPF) combined with parenteral nutrition to total parenteral nutrition (TPN) in the treatment of SAP rats. Our analysis revealed that the combination of enteral nutrition and parenteral nutrition was more effective than TPN in SAP. And LZ-FP met the requirements for enteral nutrition of SAP supporting its clinical application in SAP. PRACTICAL APPLICATIONS: Luzhou-Feier powder (LZ-FP) is a traditional Chinese nutritional supplement that was originally developed as a nutritional supplement for infants and is currently used for nutritional support in patients with chronic and consumptive diseases. Our research investigated the effect and its possible mechanisms of LZ-FP as early trophic enteral nutrition in SAP rats and compared it with TPF and TPN which have been used clinically. We found that LZ-FP helped to reduce inflammatory response and improve the intestinal immune barrier of SAP. The curative effect of LZ-FP was comparable to that of TPF. And this effect may be achieved by inducing the secretion of gut hormones. Our research indicates that LZ-FP should be considered as an enteral nutrition preparation for SAP.

Triglyceride and glucose (TyG) index is an effective biomarker to identify severe acute pancreatitis

BackgroundEarly diagnosis of severe acute pancreatitis (AP) is important to reduce morbidity and mortality. We investigated the association between the triglyceride and glucose index (TyG index) and the prognosis of severe AP (SAP). MethodsThe TyG index was calculated as: ln [fasting triglycerides (mg/dL) x fasting plasma glucose (mg/dL)]/2. Multivariable logistic regression analyses were used to investigate the independent association between the TyG index and the severity of AP. ResultsIn this study, 373 patients with AP were recruited from three hospitals. The TyG index was higher in the SAP group than in the non-SAP group. Further, the TyG index was higher than in patients admitted to an intensive care unit and those who died of AP. The TyG index was an independent predictive factor for SAP (odds ratio 7.14, 95% confidence interval 2.80–18.19). The area under the curve increased significantly, from 0.738 to 0.830, after adding the TyG index to a predictive SAP model. ConclusionsOur findings suggest that the TyG index is an independent prognostic factor in patients with AP and could be used as a simple prognostic indicator for SAP.

Procalcitonin, C-reactive Protein, and Neutrophil Ratio Contribute to the Diagnosis and Prognosis of Severe Acute Pancreatitis

We aimed to explore the significance of procalcitonin (PCT), C-reactive protein (CRP) and neutrophil ratio (N%) in the early diagnosis, treatment, and prognosis of severe acute pancreatitis (SAP). A total of 104 patients with SAP (SAP group) and 101 patients with mild acute pancreatitis (MAP) (MAP group) admitted to Affiliated Hospital of Jining Medical University, Jining, China were enrolled. The PCT and CRP in serum were detected by a full-automatic biochemical analyzer, and N% in peripheral blood was measured by a hemocyte analyzer. The peripheral blood PCT, CRP, and N% in the SAP group were significantly higher than those in the MAP group (P<0.001). Multivariate Logistic regression analysis showed that acute physiology and chronic health evaluation II (APACHE II) score, Ranson score, PCT, CRP, and N% were independent risk factors for SAP. The receiver operating characteristic (ROC) curve showed that the area under curve (AUC) of PCT, CRP, and N% in diagnosing SAP were 0.906, 0.840, and 0.834 respectively, while that of combined detection was 0.972. The AUC of PCT, CRP, and N% in diagnosing SAP death were 0.907, 0.900, and 0.894, respectively. Peripheral blood PCT, CRP, and N% contribute to the diagnosis and prognosis of SAP.

Expression and clinical significance of microRNA-21-3p and microRNA-551-5p in patients with acute pancreatitis

To investigate the diagnostic and diagnostic values of plasma microRNA-21-3p (miR-21-3p) and miR-551-5p expression in patients with acute pancreatitis (AP). A prospective observational study was conducted. AP patients admitted to the Third People's Hospital of Hainan Province from January 1st 2017 to December 31st 2019 were enrolled. The patients were divided into mild acute pancreatitis (MAP) group, moderate severe acute pancreatitis (MSAP) group and severe acute pancreatitis (SAP) group according to their severity. Fasting venous blood was collected from all subjects the day after admission, and real-time quantitative polymerase chain reaction (PCR) as used to detect the expression levels of plasma miR-21-3p and miR-551-5p. Rehabilitation, discharge or death were end points of study. In addition, 50 healthy people in the same period were selected as the control group. The receiver operating characteristic (ROC) curve was used to analyze the value of the expression levels of plasma miR-21-3p and miR-551-5p for the diagnosis and prognosis of SAP. Pearson correlation was used to analyze the relationship between the expressions of miR-21-3p and miR-551-5p in SAP patients. A total of 164 AP patients were enrolled, including 72 MAP patients, 47 MSAP patients and 45 SAP patients. Among the SAP patients, 27 cases survived and 18 cases died. There were no deaths in MAP group and MSAP group. The levels of plasma miR-21-3p and miR-551-5p in AP group were significantly higher than those in control group [miR-21-3p (2-ΔΔCt): 2.17±0.90 vs. 0.65±0.12, miR-551-5p (2-ΔΔCt): 1.80±0.73 vs. 0.42±0.08, both P < 0.01]. The expression levels of plasma miR-21-3p and miR-551-5p in AP patients increased gradually with the aggravation of the disease (F values were 11.635, 10.204 respectively, both P < 0.01), and the expression levels of plasma miR-21-3p and miR-551-5p in SAP group were significantly higher than those in MSAP group and MAP group [miR-21-3p (2-ΔΔCt): 3.16±1.08 vs. 1.85±0.71, 1.70±0.64; miR-551-5p (2-ΔΔCt): 2.63±0.95 vs. 1.52±0.46, 1.36±0.40; all P < 0.01]. ROC curve analysis showed that the area under the ROC curve (AUC) and 95% confidence interval (95%CI) of the joint diagnosis of SAP with miR-21-3p and miR-551-5p were significantly higher than that of miR-21-3p or miR-551-5p alone [0.898 (0.841-0.960) vs. 0.820 (0.763-0.882), 0.806 (0.748-0.867), Z1 = 4.480, Z2 = 4.916, both P < 0.05], and the sensitivity was 90.7% and the specificity was 85.0%. The expression levels of plasma miR-21-3p and miR-551-5p in the death group of SAP patients were significantly higher than those in the survival group [miR-21-3p (2-ΔΔCt): 3.75±1.17 vs. 2.66±0.87, miR-551-5p (2-ΔΔCt): 3.17±1.04 vs. 2.24±0.83, both P < 0.01]. ROC curve analysis showed that the AUC and 95%CI of the combined prediction of death in SAP patients with miR-21-3p and miR-551-5p were significantly higher than that of miR-21-3p or miR-551-5p alone [0.933 (0.875-0.996) vs. 0.856 (0.794-0.917), 0.816 (0.759-0.874), Z1 = 4.395, Z2 = 5.520, both P < 0.05], and the sensitivity was 95.2% and the specificity was 87.5%. Correlation analysis showed a positive correlation between the expression level of plasma miR-21-3p and miR-551-5p in SAP patients (r = 0.827, P < 0.001). The increased expression of plasma miR-21-3p and miR-551-5p are positively correlated with the severity of AP patients. The combination of the two items has a better value in the diagnosis and prognosis evaluation of SAP.

Circulating CD14+CD163+CD115+ M2 monocytes are associated with the severity of new onset severe acute pancreatitis in Chinese patients

BackgroundDespite the role of monocytes in the pathogenesis of severe acute pancreatitis (SAP), it remains unclear how different subtypes of monocytes regulate and contribute to this pathogenesis. MethodsWe examined the numbers of different subsets of monocytes by flow cytometry in 21 SAP, 15 mild acute pancreatitis (MAP) and 13 healthy controls (HC). The concentrations of plasma cytokines were assessed by cytometric bead array. Disease severity was evaluated based on the acute physiology and chronic health evaluation (APACHE) II score and plasma C-reactive proteins (CRP) levels. ResultsCompared with the numbers in MAP patients and HC, we observed that the numbers of CD14+CD163−, CD14+CD163−MAC387+, CD14+CD163−IL-12+ M1 monocytes, and CD115+, CD204+, IL-10+ M2 monocytes were significantly increased in SAP patients. In addition, these patients showed higher plasma levels of interleukin (IL)-12 and IL-10. Furthermore, the number of CD14+CD163−, CD14+CD163−MAC387+ M1 monocytes and the plasma IL-12 concentration showed a positive association with the CRP level, while the number of CD204+, IL-10+ M2 monocytes and the plasma IL-10 concentration showed a positive correlation with the APACHE II score. Importantly, the CD115+ M2 subset displayed a positive correlation with both the CRP level and APACHE II score, and treatment of SAP significantly reduced the number of this subset. ConclusionsThe CD14+CD163+CD115+ M2 monocyte count appears to be important factor in determining the severity and prognosis of SAP. Both the pro- and anti-inflammatory monocytes appear to participate in the pathogenesis of SAP.

Effect of early controlled fluid resuscitation combined with traditional Chinese medicine treatment on the prognosis of severe acute pancreatitis

Effect of early controlled fluid resuscitation combined with traditional Chinese medicine treatment on the prognosis of severe acute pancreatitis

The Prognosis of Severe Acute Pancreatitis Varies According to the Segment Presenting With Low Enhanced Pancreatic Parenchyma on Early Contrast-Enhanced Computed Tomography: A Multicenter Cohort Study.

The aim of this study was to investigate the outcomes of severe acute pancreatitis (SAP) according to the segment presenting with low enhanced pancreatic parenchyma (LEPP) on early contrast-enhanced computed tomography. This was a post hoc analysis of a multicenter, retrospective study conducted at 44 institutions in Japan. Patients diagnosed as having SAP according to the Japanese Severity Score between January 2009 and December 2013 were included. We compared the effect of LEPP in each segment on mortality. A total of 1097 patients were assessed. The numbers of patients with LEPP in the pancreatic head (Ph), body (Pb), or tail (Pt) were 272, 273, and 204 (with some overlaps), respectively. In multivariate analysis, LEPP in Ph and Pt was significantly related to mortality (odds ratio [OR], 1.94; 95% confidence interval [CI], 1.11-3.40 [P < 0.05], for LEPP in Ph; OR, 2.44; 95% CI, 1.27-4.67 [P < 0.05], for LEPP in Pt), but LEPP in Pb was unrelated to mortality (OR, 0.70; 95% CI, 0.35-1.37; P = 0.30). Presence of LEPP in Ph and Pt on early contrast-enhanced computed tomography was independently associated with increased mortality in SAP. These patients require close observation to ensure timely and adequate intervention.

Increased admission serum cold-inducible RNA-binding protein concentration is associated with prognosis of severe acute pancreatitis

BackgroundCold-inducible RNA-binding protein (CIRP) is a pro-inflammatory cytokine. This study assessed its relation to disease severity and major adverse events (namely local complications, organ failure and in-hospital mortality) of severe acute pancreatitis (SAP) and its discriminatory ability for SAP. MethodsThis prospective and observational study recruited a total of 102 SAP patients, 48 patients with mild acute pancreatitis and 102 healthy individuals. Serum CIRP concentrations were determined using enzyme-linked immunosorbent assay. ResultsSerum CIRP concentrations were significantly higher in patients compared to controls. Serum CIRP concentrations were highly correlated with the circulating concentrations of common inflammatory mediators (i.e., procalcitonin, C-reactive protein and white blood cell) and the traditional predictors of disease severity (namely Acute Physiology and Chronic Health Care Evaluation II score, Ranson score, multiple organ dysfunction score and sequential organ failure assessment score). CIRP in serum was an independent predictor for major adverse events. Serum CIRP concentrations showed high predictive value for major adverse events, and possessed high discriminatory performance for SAP. Moreover, its effects significantly exceeded those of the preceding inflammatory mediators. ConclusionsIncreased serum CIRP concentrations clearly reflect SAP severity and prognosis and significantly distinguish SAP, substantializing CIRP as a potential SAP biomarker.

Serological diagnosis and prognosis of severe acute pancreatitis by analysis of serum glycoprotein 2.

Glycoprotein 2 (GP2), the pancreatic major zymogen granule membrane glycoprotein, was reported to be elevated in acute pancreatitis in animal models. Enzyme-linked immunosorbent assays (ELISAs) were developed to evaluate human glycoprotein 2 isoform alpha (GP2a) and total GP2 (GP2t) as specific markers for acute pancreatitis in sera of 153 patients with acute pancreatitis, 26 with chronic pancreatitis, 125 with pancreatic neoplasms, 324 with non-pancreatic neoplasms, 109 patients with liver/biliary disease, 67 with gastrointestinal disease, and 101 healthy subjects. GP2a and GP2t levels were correlated with procalcitonin and C-reactive protein in 152 and 146 follow-up samples of acute pancreatitis patients, respectively. The GP2a ELISA revealed a significantly higher assay accuracy in contrast to the GP2t assay (sensitivity ≤3 disease days: 91.7%, specificity: 96.7%, positive likelihood ratio [LR+]: 24.6, LR-: 0.09). GP2a and GP2t levels as well as prevalences were significantly elevated in early acute pancreatitis (≤3 disease days) compared to all control cohorts (p<0.05, respectively). GP2a and GP2t levels were significantly higher in patients with severe acute pancreatitis at admission compared with mild cases (p<0.05, respectively). Odds ratio for GP2a regarding mild vs. severe acute pancreatitis with lethal outcome was 7.8 on admission (p=0.0222). GP2a and GP2t levels were significantly correlated with procalcitonin [Spearman's rank coefficient of correlation (ρ)=0.21, 0.26; p=0.0110, 0.0012; respectively] and C-reactive protein (ρ=0.37, 0.40; p<0.0001; respectively). Serum GP2a is a specific marker of acute pancreatitis and analysis of GP2a can aid in the differential diagnosis of acute upper abdominal pain and prognosis of severe acute pancreatitis.
