ABSTRACT
Producto de una pancreatitis aguda (PA) puede haber una diabetes posterior o una hiperglicemia transitoria durante el episodio de PA. La incidencia de PA en edad pediátrica es de hasta 12,2 casos por 100 000 niños al año y sólo el 4 a 5% desarrollan luego diabetes. Con respecto a la hiperglicemia transitoria en niños, la información es escasa y no se ha hecho publicaciones al respecto en nuestro país. Se reporta el caso de una niña con hiperglicemia transitoria secundaria a una PA necrotizante grave. Es importante realizar un monitoreo constante de los niveles de glucosa y el tratamiento oportuno de la hiperglicemia en niños con PA ya que, al menos en adultos, se asocia a PA severa y mayor mortalidad.
As a result of acute pancreatitis (AP), there may be subsequent diabetes or transient hyperglycemia during the episode of AP. The incidence of AP in pediatric age is up to 12.2 cases per 100,000 children per year and only 4 to 5% later develop diabetes. Regarding transient hyperglycemia in children, information is scarce, and no publications have been made about it in our country. The case of a girl with transient hyperglycemia secondary to severe necrotizing AP is reported. It is important to constantly monitor glucose levels and timely manage hyperglycemia in children with AP since, at least in adults, it is associated with severe AP and higher mortality.
ABSTRACT
Objective:To investigate the effect of T-lymphocyte and subpopulation counts on the prognosis of severe acute pancreatitis (SAP) patients.Methods:The clinical data of 90 patients with SAP diagnosed at the Shanghai General Hospital between January 2019 and June 2022 were retrospectively analyzed, and the patients were divided into good prognosis and poor prognosis group according to whether they were diagnosed for 28 d. The general information of the patients was recorded, including blood-related immunological indicators within 24 h of diagnosis, including leukocytes, neutrophils, lymphocytes, monocytes, CD 3+ , CD 4+ , CD 8+ T-lymphocyte count and CD 4+ /CD 8+ T-lymphocyte ratio, IgG4 level; blood inflammation index procalcitonin, albumin level and APACHEⅡ score at admission; survival and complication status of patients at 28 d of diagnosis. Non-parametric Mann-Whitney U test was used to analyze the correlation between each index and the prognosis of the patients. The subject operating characteristic curve (ROC) of patients was plotted, and area under curve (AUC) was calculated to assess the value of CD 3+ and CD 4+ T-lymphocytes in predicting the prognosis of SAP. Results:The majority of SAP patients were male (65.6%). The main cause of SAP was gallstone (56.7%), followed by hyperlipidemia (35.6%). At 28 days after diagnosis, 85(94.4%) patients survived, and 39 of them were cured and included in the good prognosis group. Forty-six cases were complicated with infection, multiple organ dysfunction syndrome (MODS) and local pancreatic complications, and 5 cases (5.56%) died; and a total of 51 cases were included in the poor prognosis group. Compared with the good prognosis group, the number of CD 3+ T-lymphocytes [366(268, 498) cells /μl vs 709(578, 999) cells /μl], CD 4+ T-lymphocytes [209(120, 298) cells /μl vs 486(303, 548) cells /μl] and albumin level (33.9 g/L vs 35.9 g/L) within 24 hours in the poor prognosis group were significantly lower, while the level of procalcitonin (1.02 ng/ml vs 0.43 ng/ml) and APACHEⅡ score [7(4, 10) vs 5(3, 8)] were significantly increased, and all the differences were statistically significant (all P value <0.05). ROC curve analysis showed that the AUC values for CD 3+ and CD 4+ T-lymphocyte counts within 24 hours for predicting poor prognosis of SAP were 0.857 (95% CI 0.696-1.000) and 0.867 (95% CI 0.708-1.000), respectively. The cut-off values were 524 cells /μl and 301 cells /μl, the sensitivity were both 85.7%, and the specificity were 78.6% and 85.7%, respectively. Conclusions:The significant decrease of peripheral blood CD 3+ and CD 4+ T-lymphocyte count within 24 h of SAP diagnosis has a certain predictive value for the prognosis of patients with SAP.
ABSTRACT
Objective:To construct a risk prediction model for infection with Klebsiella pneumonia (KP) for patients with severe acute pancreatitis (SAP).Methods:Retrospective analysis was done on the clinical data of 109 SAP patients who were admitted to Shanghai General Hospital, between March 2016 and December 2021. Patients were classified into infection group ( n=25) and non-infection group ( n=84) based on the presence or absence of KP infection, and the clinical characteristics of the two groups were compared. The least absolute shrinkage and selection operator (LASSO) algorithm was used to reduce the dimension of the variables with statistical significance in univariate analysis. A nomogram prediction model was created by incorporating the optimized features from the LASSO regression model into the multivariate logistic regression analysis. Receiver operating characteristic curve (ROC) was drawn and the area under curve (AUC) was calculated; and consistency index (C-index) were used to assess the prediction model's diagnostic ability. Results:A total of 25 strains of KP were isolated from 109 patients with SAP, of which 21(84.0%) had multi-drug resistance. 20 risk factors (SOFA score, APACHEⅡ score, Ranson score, MCTSI score, mechanical ventilation time, fasting time, duration of indwelling of the peritoneal drainage tube, duration of deep vein indwelling, number of invasive procedures, without or with surgical intervention, without or with endoscopic retrograde cholangiopancreatography (ERCP), types of high-level antibiotics used, digestion disorders, abnormalities in blood coagulation, metabolic acidosis, pancreatic necrosis, intra-abdominal hemorrhage, intra-abdominal hypertension, length of ICU stay and total length of hospital stay) were found to be associated with KP infection in SAP patients by univariate analysis. The four variables (APACHEⅡ score, duration of indwelling of the peritoneal drainage tube, types of high-level antibiotics used, and total length of hospital stay) were extracted after reduced by LASSO regression. These four variables were found to be risk factors for KP infection in SAP patients by multiple logistic regression analysis (all P value <0.05). Nomogram prediction model for KP infection in SAP was established based on the four variables above. The verification results of the model showed that the C-index of the model was 0.939, and the AUC was 0.939 (95% CI 0.888-0.991), indicating that the nomogram model had relatively accurate prediction ability. Conclusions:This prediction model establishes integrated the basic clinical data of patients, which could facilitate the risk prediction for KP infection in patients with SAP and thus help to formulate better therapeutic plans for patients.
ABSTRACT
ABSTRACT Alcoholic foamy degeneration (AFD) is an uncommon presentation of alcoholic liver disease (ALD) with characteristic histologic findings of foamy-looking hepatocytes due to the presence of abundant microvesicles of fat within the cytoplasm predominantly in perivenular and midzonal regions without inflammation and fibrosis. It is underdiagnosed as the patients quickly recover after alcoholic abstinence and are rarely caught on biopsies. AFD has better prognosis than alcoholic hepatitis, and the injury mechanism is different, warranting a different diagnosis. We present an uncommon case of AFD incidentally diagnosed during autopsy in a chronic alcoholic and diabetic man.

Conclusion Current evidence shows that biliary etiology and alcoholic etiology are unique influencing factors for ANP in the Eastern population, while Ranson score is a unique influencing factor in the Western population.BMI and extent of necrosis ≥30% are unique influencing factors for IPN in the Eastern population, while alcoholic etiology is a unique influencing factor in the Western population.
ABSTRACT
Objective To investigate the value of pancreatitis activity scoring system (PASS) score, Bedside Index for Severity in Acute Pancreatitis (BISAP) score, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE-Ⅱ) score, harmless acute pancreatitis score (HAPS), and Ranson score in evaluating the severity and prognosis of hypertriglyceridemia acute pancreatitis (HTGAP). Methods A retrospective analysis was performed for the clinical data of 300 patients with HTGAP who were admitted to General Hospital of Ningxia Medical University from January 2016 to January 2022, and according to the disease severity, these patients were divided into mild acute pancreatitis (MAP) group, moderate-severe acute pancreatitis (MSAP) group, and severe acute pancreatitis (SAP) group. Clinical data and the above scores were compared between the three groups. The chi-square test was used for comparison of categorical data between groups; an analysis of variance was used for continuous data with homogeneity of variance, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted according to disease severity, and related indicators were compared in terms of the area under the ROC curve (AUC). Results There were significant differences between the three groups in PASS score ( F =219.351, P < 0.01), Ranson score ( χ 2 =83.084, P < 0.01), APACHE-Ⅱ score ( χ 2 =43.388, P < 0.01), and BISAP score ( χ 2 = 50.785, P < 0.01). Compared with the other four scoring systems in evaluating and predicting disease severity, PASS score had the highest sensitivity of 0.945 and the largest AUC of 0.963, followed by Ranson score with a sensitivity of 0.655 and an AUC of 0.819. Conclusion For patients with HTGAP, PASS score can more accurately assess the severity and prognosis of HTGAP patients and thus holds promise for clinical application.

ABSTRACT
Objective:To investigate the relationship between serum interleukin-6 and interleukin-10 levels and clinical prognosis in patients with severe acute pancreatitis.Methods:Ninety-two patients with severe acute pancreatitis who received treatment in The Second People's Hospital of Liaocheng from August 2018 to July 2021 were included in this study. Serum interleukin (IL)-6 and IL-10 levels were detected. The Bedside Index of Severity in Acute Pancreatitis (BISAP) score was evaluated. Clinical interventions were performed. The relationship between serum IL-6 and IL-10 levels and the clinical prognosis of severe acute pancreatitis was investigated.Results:Serum IL-6 level [(103.75 ± 15.53) ng/L] was highest in patients who died. Serum IL-10 level [(97.33 ± 13.06) ng/L] was highest in patients with local complications. The highest number of patients with a prognostic outcome of death [26 (37.14%)] was found in patients with a BISAP score ≥ 3. Serum IL-6 level in patients with severe acute pancreatitis was positively correlated with the BISAP score ( r = 0.62, P < 0.05), and serum IL-6 level and BISAP score were negatively correlated with serum IL-10 level ( r = -0.57, -0.61, both P < 0.05). Conclusion:Increased or decreased serum IL-6 and IL-10 levels in patients with severe acute pancreatitis indicate that the patient's condition tends to worsen, and timely intervention according to serum IL-6 and IL-10 levels can improve the clinical prognosis of severe acute pancreatitis.
ABSTRACT
Objective:To construct the prediction model of SAP complicated with intra-abdominal hypertension (IAH), and evaluate the prediction efficiency of the model.Methods:The clinical data of 322 SAP patients admitted to the emergency department of Cangzhou Hospital of Integrated Chinese and Western Medicine in Hebei Province from January 2017 to December 2021 were retrospectively analyzed. They were divided into IAH group ( n=153) and control group ( n=169) according to whether they had IAH complications or not. The clinical characteristics and laboratory test results of the two groups were compared. Multifactor logistic step-up regression was used to analyze the risk factors of SAP patients complicated with IAH. A nomogram model for predicting SAP complicated with IAH was established by using R software. The receiver operating characteristic curve (ROC) of the model was plotted, and the area under the curve (AUC) was calculated to evaluate its prediction efficiency. Calibration chart, Hosmer-Lemesshow test and decision curve analysis were used to evaluate the prediction accuracy and clinical application value of the model. The Bootstrap method was applied to verify the model internally. Results:In IAH group, cases with body mass index, CRP, procalcitonin (PCT), WBC, acute physiological and chronic health assessmentⅡ (APACHEⅡ) score, modified CT Severity Index score (MCTSI), incidence of complications (abdominal effusion, abdominal infection, gastrointestinal dysfunction, shock, multiple organ dysfunction syndrome), mechanical ventilation, the number of high-volume fluid reactivation (24 h≥4 L) were more than those in control group; serum albumin and serum calcium in IAH group were lower than those in control group, and the differences were statistically significant (all P value <0.05). Multivariate logistic regression analysis showed that serum albumin ( OR=0.815, 95% CI 0.710-0.937), CRP ( OR=1.005, 95% CI 1.002-1.008), MCTSI ( OR=2.043, 95% CI 1.695-2.463), complication of gastrointestinal dysfunction ( OR=4.179, 95% CI 2.170-8.049), and high-volume fluid resuscitation ( OR=4.265, 95% CI 2.269-8.015) were independent risk factors for IAH in SAP.The Nomogram prediction model was established using the five factors above as parameters, and the AUC value for predicting IAH complication was 0.886. The Hosmer-Lemesshow test showed a high consistency between the prediction results and the actual clinical observation results ( P=0.189). The results of decision curve analysis showed that the prediction probability of the model was between 10% and 85%, which could bring more benefits to patients. Conclusions:The early prediction model of SAP with concurrent IAH is successfully established, which can better predict the risk of SAP with concurrent IAH.
ABSTRACT
Objective:To explore the effect of probiotics Lactiplantibacillus plantarum(LP) WCFS1 by gavage on acute necrotizing pancreatitis (ANP) and associated ileum injury in mice. Methods:Twenty-four healthy male mice were gavaged with broad-spectrum antibiotics for 3 weeks to establish microbiota-depleted mice, and then randomly divided into control group (CON), ANP model group (ANP), LP gavage group (LP) and LP gavage and ANP induced group (LP+ ANP) , with 6 mice in each group. Mice in LP and LP+ ANP group were treated by gavage of LP (1×10 9 CFU/ml, 0.2 ml/day per mouse) for 1 week, while CON and ANP were gavaged with sterile phosphate buffered saline for 1 week instead. The ANP model was induced by intraperitoneal injection with caerulein (100 μg/kg) for 10 times with 1-hour interval between two injections and the 10th injection with lipopolysaccharide(LPS) 5 mg/kg intraperitoneally, and the mice were sacrificed 2 h later. Levels of LP in stool and ileal mucosa were detected by real-time PCR; the pancreas and ileum were collected for pathological examination to observe the extent of tissue inflammation and to score the pathology. Serum amylase activities were determined by enzymatic kinetic chemistry; serum inflammators levels and intestinal permeability were detected by ELISA; levels of inflammators in pancreatic and ileal tissues were detected by real-time PCR; ileal tight-junction proteins (occludin, claudin-1 and ZO-1) were measured by immunofluorescence staining. Results:LP levels in the stool and ileal mucosa of mice were significantly increased after LP gavage, and the differences were statistically significant (913.30±39.12 vs 2.39±1.39, 23.11±0.50 vs 1.38±0.28, all P value <0.05). The pathological scores of pancreatic tissue of CON, LP, ANP and LP+ ANP group were (0.26±0.41), (0.17±0.26), (8.55±0.46) and (6.30±0.45); the serum amylase activities were (219.70±19.73), (217.60±11.30), (2896.24±98.32) and (1837.13±131.60)U/L, IL-1β were (0.87±0.28), (1.4±0.85), (67.41±6.45) and (36.33±5.65)pg/ml, IL-6 were (0.74±0.27), (0.16±0.16), (280586.12±39163.92) and (107912.75±31283.47)pg/ml, IL-10 were (35.52±5.27), (50.99±15.34), (2008.45±184.83) and (3070.35±403.71)pg/ml; the expression level of pancreatic IL-1β mRNA was 1.42±0.39, 0.95±25, 20.53±0.50 and 10.69±1.01, IL-6 mRNA was 1.31±0.44, 0.93±0.023, 21.97±1.71 and 11.54±1.75, IL-10 mRNA was 0.93±0.14, 0.75±0.15, 0.99±0.21 and 1.76±0.19; there was no significant difference between LP and CON group, and pancreatic pathological scores, serum amylase、IL-1β and IL-6 levels, and the expression level of pancreatic IL-1β and IL-6 mRNA were significantly decreased in LP+ ANP group compared with those in ANP group, while serum IL-10 levels and the expression level of pancreatic IL-10 mRNA were significantly increased compared with ANP group, and all the differences were statistically significant (all P values <0.05). The pathological scores of ileal tissue of CON, LP, ANP and LP+ ANP group were 0, 0, (3.17±0.41) and (1.67±0.52); the levels of serum DAO of CON, LP, ANP and LP+ ANP group were (0.03±0.03), (0.02±0.02), (0.50±0.05) and (0.49±0.06)ng/ml; LPS levels were (2.75±0.35), (3.74±0.28), (7.19±0.92) and (5.88±0.38)ng/ml; the expression level of ileal IL-1β mRNA was 1.21±0.20, 1.17±0.09, 1.81±0.25 and 1.63±0.21; IL-6 mRNA was 1.01±0.29, 2.83±0.42, 54.45±8.50 and 16.87±4.42; IL-10 mRNA was 1.12±0.41, 6.09±2.51, 11.65±1.47 and 29.86±2.93.

Conclusions:LP WCFS1 gavage could ameliorate the injury of pancreatic and ileal barrier in caerulein-induced ANP mice.
ABSTRACT
Objective:To analyse the clinical efficacy and outcome of early abdominal paracentesis drainage (APD) in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 107 SAP patients with massive abdominal fluid in Shanghai General People Hospital from May 2017 to December 2021 were collected and analyzed. Patients were divided into APD group ( n=56) and NO-APD group ( n=51) according to whether they underwent APD or not within 3 days after admission. The APD group was then divided into abdominal compartment syndrome (ACS) subgroup ( n=29) and NO-ACS subgroup ( n=27) according to whether ACS had occurred or not at the time of puncture. Patients' general data, the duration of systemic inflammatory response (SIRS), length of ICU stay, the trends of intra-abdominal pressure and inflammatory indicators (white blood cell count and the content of C-reactive protein) within 1-3 days after admission, incidence of infection complication, step-up therapy, discharge or death were recorded. Results:The intra-abdominal pressure were 18.6±5.6mmHg , 13.7±4.2mmHg (1 mmHg=0.133 kpa) in APD group and NO-APD group, respectively. The intra-abdominal pressure of APD group was significantly higher than that of NO-APD group, and the difference was statistically significant ( P=0.000). Compared with NO-APD group, the duration of SIRS was significantly shortened in APD group [3(2, 4) days vs 4(3, 6) days, P=0.029]. On day 1, 2 and 3 after admission, the intra-abdominal pressure was 18.6±5.6 mmHg, 16.4±4.7 mmHg and 13.5±3.9 mmHg in APD group, and was 13.7±4.2 mmHg, 12.3±3.6 mmHg and 11.0±2.6 mmHg in NO-APD group, respectively. The intra-abdominal pressure of the APD group dropped faster than the NO-APD group ( P=0.004). The white blood cell count was (14.8±4.8), (10.5±4.5) and (9.0±3.8)×10 9/L in APD group, and was (14.2±5.4), (12.3±7.3), (11.7±5.3)×10 9/L in NO-APD group, respectively. Compared with the NO-APD group, the decrease rate of white blood cell count was faster in APD group ( P=0.006). The C-reactive protein content was (153.6±47.1), (150.4±10.5) and (108.8±49.4)mg/L in APD group, and were (174.8±31.1), (191.6±29.4) and (186.8±45.5)mg/L in NO-APD group . The content of C-reactive protein in APD group decreased significantly, while that in NO-APD group did not decrease. There was a significant difference between the two groups ( P=0.009). In the subgroup comparisons, the duration of SIRS in the ACS subgroup was significant longer than that in the NO-ACS subgroup [4(3, 5) days vs 2(1, 3)days, P=0.000]. Compared between the two groups and two subgroups respectively, there were no statistically significant differences on length of ICU stay, infection complication rate, advanced treatment rate and mortality. Conclusions:For SAP patients with abdominal fluid, APD in the early stage could shorten the duration of SIRS, decrease intra-abdominal pressure rapidly, improve inflammatory indicators, but could not improve the clinical outcome.
ABSTRACT
Objective:To evaluate the clinical efficacy of continuous renal replacement therapy (CRRT) with adsorptive filter oXiris in the treatment of severe acute pancreatitis (SAP).Methods:The clinical data of 5 SAP patients who received the treatment of absorptive filter oXiris in Department of Critical Care Medicine of Shanghai General Hospital from February 2021 to February 2022 were collected. The changes of inflammatory indicators, hemodynamics, acid-base balance indicators and organ function indicators were compared before and 24 h after treatment.Results:Before the treatment of oXiris, 3 patients had pancreatic necrotic infection, and all the five patients had systemic inflammatory response syndrome(SIRS), acute respiratory and circulatory failure and acute renal injury. At 24 h after the treatment with oXiris, the levels of inflammatory indicators such as white blood cell count [(13.4±5.0)×10 9/L vs (25.8±10.0)×10 9/L), CRP [(149.6±68.3)mg/L] vs (289.0±129.4)mg/L] and procalcitonin [3.7(1.4, 17.7)ng/ml vs 12.2(3.2, 62.9)ng/ml] in the blood samples from the patients were greatly decreased. Hemodynamics were obviously improved; heart rate [(107.4±9.5)bpm/min vs (143.4±9.7)bpm/min] was decreased, and the mean artery pressure [(87±5)mmHg vs (73±13)mmHg], 1 mmHg=0.133 kPa] tended to be stabilized. Metabolic acidosis was significantly improved; pH value (7.4±0.0 vs 7.2±0.1) and base excess (-2.1±2.5 vs -14.5±6.1) were increased, while lactic acid [(2.6±1.2)mmol/L vs (10.62±6.55)mmol/L] was decreased. Organ dysfunctions were improved; PaO 2/FiO 2 value (241.7±58.5 vs 115.9±53.6) was increased, while serum creatinine [(148.0±42.5)μmol/L vs (232.8±77.4)μmol/L], intra-abdominal pressure [(18.6±4.5)mmHg vs (24.2±4.0)]mmHg, modified Marshall score [3(3.0, 4.0) vs 6(5.5, 9.0)] and APACHEⅡ score (17.6±2.9 vs 26.0±5.2) were decreased. All the differences above were statistically significant (all P value <0.05). Conclusions:It is safe and feasible to treat SAP patients with CRRT by using oXiris in clinical practice, which may have the functions of clearing inflammatory mediators, stabilizing hemodynamics and acid-base balance and improving organ function.
ABSTRACT
Presentamos el caso de un varón de 64 años quien, tras un primer episodio de pancreatitis aguda necrotizante, reingresa a los 20 días por cuadro de dolor epigástrico intenso y posteriormente episodio de hemorragia digestiva alta en forma de hematemesis y melenas con inestabilización hemodinámica. Se realiza en ese momento gastroscopia urgente objetivándose probable fistula gastrointestinal en bulbo duodenal con coágulo adherido sin sangrado activo en ese momento por lo que se realiza angio-TC urgente que revela colección peripancreática necrótica con presencia de sangrado activo en su interior, procedente de la arteria pancreatoduodenal. La arteriografía urgente identificó imagen compatible con pseudoaneurisma arterial dependiente de la rama de arteria pancreatoduodenal, que fue embolizada con éxito. Desgraciadamente el paciente falleció en las horas posteriores, como consecuencia de un shock séptico secundario a colección pancreática infectada.
We present the case of a 64-year-old man who, after a first episode of acute pancreatitis, was readmitted 20 days later due to severe epigastric pain and later an episode of upper gastrointestinal bleeding in the form of hematemesis and melena with hemodynamic instability. An urgent gastroscopy was performed at that time, revealing a probable gastrointestinal fistula in the duodenal bulb with an adherent clot without active bleeding at that time, so an urgent CT angiography was performed that revealed a necrotic peripancreatic collection with the presence of active bleeding inside from the pancreatoduodenal artery. Urgent arteriography identified an image compatible with arterial pseudoaneurysm dependent on the pancreaticoduodenal artery branch, which was successfully embolized. Unfortunately, the patient died a few hours later as a result of septic shock secondary to an infected pancreatic collection.
ABSTRACT
RESUMEN Introducción: La pancreatitis es la inflamación del páncreas exocrino, resultado del daño a las células acinares. Sus características clínicas principales son el dolor abdominal y la elevación de los niveles séricos de amilasa y lipasa. La evolución es muy variable, desde una recuperación completa de un primer episodio, hasta una enfermedad crónica debilitante, o la muerte. Objetivos: Caracterizar a los pacientes ingresados en la unidad de cuidados intensivos, con el diagnóstico de pancreatitis aguda y evaluarlos según los criterios de gravedad. Métodos: Se realizó un estudio descriptivo en el que se revisaron 46 historias clínicas de pacientes ingresados con diagnóstico de pancreatitis aguda en la unidad de terapia intensiva polivalente, desde enero del 2014 a diciembre del 2019. Se confeccionó una base de datos con las variables edad, etiología, complicaciones, letalidad y la aplicación de escalas de Ranson, APACHE II y Balthazar-Hill, para evaluar evolutivamente la gravedad y pronóstico. Se hizo un análisis de frecuencias de dichas variables. Resultados: La edad de mayor incidencia correspondió a los grupos menores de 61 años, con predominio del sexo masculino. La causa más frecuente fue la litiasis vesicular y el alcoholismo, para un 43,4 % y 34,7 % respectivamente. El 47,8 % presentó la forma leve de la enfermedad. La letalidad fue del 21,7 %. Conclusiones: Son más frecuentes las formas graves de la enfermedad; la insuficiencia renal aguda y la insuficiencia respiratoria aguda son las complicaciones más representativas.
ABSTRACT Introduction: Pancreatitis is the inflammation of the exocrine pancreas, as a result of damage to the acinar cells. Its main clinical features are abdominal pain and elevated serum levels of amylase and lipase. The evolution is very variable, from a complete recovery from a first episode, to a debilitating chronic disease, or death. Objectives: To characterize patients admitted to the intensive care unit with a diagnosis of acute pancreatitis and to evaluate them according to severity criteria. Methods: A descriptive study was carried out in which 46 medical records of patients admitted with a diagnosis of acute pancreatitis in the multipurpose intensive care unit were reviewed, from January 2014 to December 2019. A database was created with the variables age, etiology, complications, lethality and the application of the Ranson, APACHE II and Balthazar-Hill scales, to evaluate severity and prognosis. An analysis of the frequencies of these variables was carried out. Results: The age with the highest incidence corresponded to groups under 61 years of age, with a predominance of males. The most frequent cause was gallstones and alcoholism, for 43.4 % and 34.7 % respectively. 47.8 % presented the mild form of the disease. The lethality was 21.7 %. Conclusions: Severe forms of the disease are more frequent; acute renal failure and acute respiratory failure are the most representative complications.
ABSTRACT
Objection To investigate the value of CT based radiomics in predicting progression of early acute pancreatitis (AP). Methods:From November 2013 to February 2021, 109 patients diagnosed with AP according to the new revised Atlanta classification in Yijishan Hospital of Wannan Medical College were retrospectively analyzed. The patients were divided into progressive group (40 cases) and non-progressive group (69 cases) according to the follow-up results. All patients underwent plain and enhanced abdominal CT scan within a week of onset. The patients were divided into training set (77 cases, including 28 cases in progressive group and 49 cases in non-progressive group) and validation set (32 cases, including 12 cases in progressive group and 20 cases in non-progressive group) in a ratio of 7∶3 using a computer completely random method. Manual region of interest mapping was performed on all levels of pancreas on the plain scan, arterial phase, venous phase and delayed phase CT images, then performed 3D fusion. AK software was used to extract texture features. The minimum redundancy maximum relevance and minimum absolute shrinkage and selection operator regression analysis were used to select features and establish radiomics labels of the plain scan, arterial phase, venous phase, delayed phase and combining the 4 sequences. The multiple logistic regression analysis was used to establish the clinical model by combining clinical features and CT features, and the comprehensive model was established by combining clinical features, CT features and imaging radiomics label. The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of each model in predicting early AP progression and the decision curve analysis (DCA) was used to evaluate the clinical application value of each model.Results:In the training set, logistic regression results showed that edge was an independent predictor (OR=0.16, P=0.033). The clinical model was established using edge and serum calcium level, and its areas under the ROC curve (AUC) in the training set and validation set were 0.69 and 0.70, respectively. Totally 14, 11, 13, 13 and 9 optimal texture features were extracted from the plain scan, arterial phase, venous phase, delayed phase and combined sequence images, respectively. The delay phase image radiomics label had relatively better predictive performance in training set and validation set, and the AUC were both 0.85. The comprehensive model was established based on the delayed phase image radiomics label (OR=2.22, P<0.001) and edge (OR=0.02, P=0.042), and the AUC in the training set and validation set was 0.90 and 0.86, respectively. DCA showed that both the comprehensive model and the delayed phase radiomics label had better benefits. Conclusions:CT radiomics model has high value for predicting progression of AP, and its clinical benefits exhibited superior performance of clinical model.
ABSTRACT
Objective:To evaluate the value of radiomics analysis based on enhanced MRI in predicting the recurrence of acute pancreatitis (AP).Methods:From January 2017 to December 2020, 201 patients diagnosed with AP were collected retrospectively in the Affiliated Hospital of North Sichuan Medical College. These patients underwent plain and enhanced MRI within 7 days after onset. After clinical follow-up, 102 cases were classified as non-recurrence AP group and 99 cases were classified as recurrent acute pancreatitis (RAP) group. They were divided into training set (140 cases, 71 cases in non-recurrence AP group, 69 cases in RAP group) and validation set (61 cases, 31 cases in non-recurrence AP group, 30 cases in RAP group) using a random number table method. The independent sample t-test, Mann-Whitney U test or χ 2 test were used to compare the clinical characteristics between the two groups, and the clinical characteristics with statistical differences were included in logistic regression to construct the clinical model. The quantitative features of radiomics were extracted based on the late arterial-phase images of contrast-enhanced MRI. The best radiomics features retained after dimensionality reduction were used to construct the radiomics model through logistic regression analysis, and a combined model was constructed by combining the clinical features. The prediction ability of the models was evaluated by the receiver operating characteristic curve, and the area under the curve (AUC) was compared by DeLong test. Results:There were statistical differences in gender, severity, local complications, hyperlipidemia and smoking between non-recurrence AP group and RAP group (all P<0.05). Hyperlipidemia was an independent risk factor for AP recurrence (OR=5.236, 95%CI 2.710-10.101). The 9 best radiomics features by dimensionality reduction were selected to construct a radiomics model. The AUCs of clinical model, radiomics model and combined model in the training set were 0.803, 0.944 and 0.978 respectively, and those in the validation set were 0.678, 0.940 and 0.955 respectively. In the training set and the validation set, the prediction ability of the radiomics model and combined model were higher than those of the clinical model (training set: Z=3.28, 4.83, P=0.001,<0.001; validation set: Z=3.48, 4.05, both P<0.001). Conclusions:The radiomics model based on late arterial-phase enhanced MRI has good quantitative prediction ability for the recurrence of AP, which can provide a reference for the prevention and treatment of RAP.
ABSTRACT
Objective:To establish an early prediction Nomogram model for severe acute pancreatitis(SAP) complicated with acute renal injury (AKI), and evaluate the prediction efficiency of the model.Methods:The clinical data of 295 SAP patients hospitalized in Zhejiang Rongjun Hospital from July 2017 to June 2021 were retrospectively analyzed, and the patients were divided into AKI group ( n=61) and non-AKI group ( n=234) according to whether complicated with AKI. The common characters, clinical data and laboratory examination results were compared. The risk factors for SAP complicated with AKI was analyzed by multivariate logistic regression analysis, and a nomogram prediction model was established by R software. The receiver operating characteristic (ROC) curve was drawn and the area under the curve (AUC) was calculated to evaluate its prediction performance. Results:The acute physiology and chronic health assessment Ⅱ (APACHEⅡ) and Ranson score, the incidence of abdominal compartment syndrome (ACS) and systemic inflammatory response syndrome (SIRS), the cases of shock and mechanical ventilation, and the levels of blood lactic acid (BLA), blood creatinine (Scr), urea nitrogen (BUN), C-reactive protein (CRP), procalcitonin (PCT) and cystatin C(Cys C) in peripheral blood were significantly higher in AKI group than those in non-AKI group, while the levels of blood calcium were lower than those in non-AKI group, and the differences were statistically significant (all P value <0.05). Multivariate logistic regression analysis showed that APACHEⅡ score ( OR=1.185, 95% CI 1.074-1.308, P=0.001), Ranson score ( OR=12.668, 95% CI 5.102-31.456, P<0.001), Scr ( OR=1.028, 95% CI 1.002-1.054, P=0.034), PCT ( OR=4.298, 95% CI 1.379-13.395, P<0.001) and Cys C ( OR=38738.38, 95% CI 43.190-347459.41, P<0.001) were independent risk factors for SAP complicated AKI. Serum calcium ( OR=0.0001, 95% 0.000-0.048, P<0.001) was an independent protective factor for SAP complicated AKI. A Nomogram prediction model based on the six factors above were established, and its AUC, sensitivity and specificity to predict AKI were 0.987, 99.0% and 98.5% in the training set, and were 0.976, 98.6% and 94.2% in the validation set. Conclusions:This study successfully established an early prediction model with high predict value for SAP complicated with AKI, which can efficiently predict the risk of SAP with concurrent AKI.
ABSTRACT
Objective:To investigate the effects of telomerase reverse transcriptase (TERT) on neutrophils apoptosis in rats with acute necrotizing pancreatitis (ANP).Methods:Twenty-four Sprague Dawley (SD) rats were randomly divided into three groups including control group, ANP (3h、6h) group and TERT inhibitor(BIBR1532)group using random number method with 6 in each group. ANP rats were induced by retrograde injection of 5% sodium taurocholate into the pancreaticcobiliary duct. After 3 and 6 hours, the fresh neutrophils were collected and isolated from peripheral blood of ANP rats. Rats were intraperitoneally injected with 2 mg/kg BIBR1532. After ANP modeling for 3 h, rats were killed and peripheral neutrophils were collected. Subsequently, the expression of TERT mRNA in neutrophils was tested by real-time quantitative PCR; the protein levels of TERT, BCL-xL and Bax were determined by Western blotting; neutrophil apoptosis was detected by flow cytometry; TNF-α and IL-6 were assayed by Elisa; the rat pancreatic tissue was pathologically examined.Results:In neutrophils from control group, ANP 3 h group, ANP 6 h group and BIBR1532 group, TERT mRNA was 1.03±0.26, 3.31±1.07, 5.21±0.78 and 1.95±0.49; TERT protein expression was 0.09±0.03, 0.43±0.12, 0.58±0.11 and 0.22±0.07; Bcl-xL protein expression was 0.19±0.05, 0.50±0.07, 0.85±0.04 and 0.40±0.11; Bax protein expression was 0.29±0.08, 0.23±0.03, 0.17±0.02 and 0.43±0.12; apoptosis rate was 10.03±0.74%, 7.99±0.27%, 6.65±0.36% and 22.98±2.86%. TERT mRNA and protein expression and Bcl-xL protein expression in ANP 3 h and 6 h group were higher than those in control group, but Bax preotein expression and apoptosis rate were lower than those in control group; TERT mRNA and protein expression and Bcl-xL protein expression in BIBR1532 group were lower than those in ANP 3 h group, but Bax protein expression and apoptosis rate in BIBR1532 group were higher than those in ANP 3 h group; and all the differences were statistically significant (all P value <0.05). The level of TNF-α was [(96.67±27.12)ng/L, (382.30±46.33)ng/L and (206.88±36.42)ng/L], IL-6 was [(43.34±14.50)ng/L, (134.21±16.13)ng/L and (88.06±13.05)ng/L in control, ANP 3 h and BIBR1532 group; those in ANP 3 h group were all higher than those in control group, but those in BIBR1532 group were lower than those in ANP 3 h group; all the differences were statistically significant (all P value <0.05). Compared with ANP group, the morphology of pancreatic tissue was obviously alleviated in BIBER1532 group. Conclusions:TERT expression is obviously increased in peripheral neutrophils in ANP rats, and apoptosis rate of neutrophils from ANP rats is greatly increased after TERT inhibitor treatment, demonstrating that TERT could inhibit the apoptosis of peripheral neutrophil in ANP rats.
ABSTRACT
Objective:To explore the core targets and potential molecular mechanisms of tetramethylpyrazine in the treatment of rats with acute necrotizing pancreatitis (ANP) based on network pharmacology.Methods:The related co-targets of tetramethylpyrazine and ANP were screened out by traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and human disease information-related databases (CTD, DisGeNET, GeneCards, OMIM); Uniprot data were used to co-link and put into the STRING database to build protein-protein interaction (PPI) networks; the Cytoscape software was used for further analysis and the key targets were obtained by using the cytoHubba plug-in. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on these key targets, and finally the molecular docking models were constructed by using PyMol and AutoDockTools software. 30 male SD rats were randomly divided into the control group, ANP group, and tetramethylpyrazine treatment group (tetramethylpyrazine group). ANP rats were induced by retrograde infusion of 4% sodium taurocholate into the biliary-pancreatic duct, and the tetramethylpyrazine group rats were injected with 10 ml/kg tetramethylpyrazine through the abdominal cavity after ANP was induced. After 12 h, pancreatic tissue was taken, a pathological examination was performed routinely, and immunohistochemical staining was performed to observe the protein expression of key targets in pancreatic tissue. Blood was taken from orbits, and then the serum IL-6 and tumor necrosis factor-α (TNF-α) levels were measured by enzyme-linked immunosorbent assay (ELISA).Results:The drug platform screened 137 tetramethylpyrazine action targets, and the disease database screened out 513 ANP-related targets; then 25 targets were obtained through intersection, finally resulting in a total of 5 key targets: albumin (ALB), epidermal growth factor receptor (EGFR), caspase 3 (CASP3), mitogen-activated protein kinase 1 (MAPK1) and B-cell lymphoma-2-like protein 1 (BCL2L1). GO functional enrichment analysis of biological processes mainly involved reproductive structure or system development, response to antibiotics, chemical stress and reactive oxygen species, and the cellular components were mainly vesicle lumen, membrane raft, membrane microdomain, and secretory granule lumen; molecular functions mainly included SH2 domain, phosphotyrosine residue, protease binding, protein tyrosine kinase and nuclear receptor activity; KEGG pathway enrichment analysis were mainly enriched in Ras signaling pathway, PI3K-Akt signaling pathway, platinum drug resistance, phospholipase D signaling pathway, and EGFR tyrosine kinase inhibitor resistance. The average binding energy of the 5 key targets molecule docking was -4.20 kcal/mol. After hematoxylin-eosin staining, it could be seen that the gland structure of rats in the ANP group was disordered, the interlobular space was significantly increased, and neutrophil infiltration was observed in the acinar, perivascular and gland space. The pancreatic lobule space of tetramethylpyrazine group rats was slightly increased, with mild neutrophil infiltration. The protein expressions of EGFR, CASP3 and MAPK1 in the ANP group were significantly higher compared with those in the control group, and EGFR, CASP3 and MAPK1 expression in tetramethylpyrazine group was significantly lower than those in ANP group ( P<0.01); the protein expression of BCL2L1 in the ANP group were significantly higher than that in control group, and the protein expression of BCL2L1 in tetramethylpyrazine group were significantly higher than that in ANP group (all P value <0.05). The serum levels of IL-6 and TNF-α in the ANP group were significantly higher than those in the control group, and IL-6 and TNF-α in tetramethylpyrazine group were significantly lower than those in the ANP group (all P value <0.01). Conclusions:Tetramethylpyrazine could reduce the inflammatory response and oxidative stress injury after ANP by activating a variety of signaling pathways, enhancing the expression of anti-apoptotic genes, and blocking the enzymatic cascade reaction of apoptotic caspase, thus playing a protective role in pancreatic tissues of rats with ANP.
ABSTRACT
Objective:To analyze the effects of infectious complications [infected pancreatic necrosis (IPN) and extra-pancreatic infection (EPI)] on the outcomes of patients with severe acute pancreatitis (SAP), and evaluate the differences in infection time, infection site and infecting species between SAP patients with infections complications.Methods:The clinical data of 66 SAP patients with combined infectious complications admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were retrospectively analyzed, and SAP patients were divided into IPN group ( n=7), EPI group ( n=14) and co-infection (EPI+ IPN) group ( n=45) according to the type of infection. Whether the study data conformed to a normal distribution was assessed by the Shapiro-Wilk test, normally distributed measures were expressed as mean ± standard deviation ( ± s), and ANOVA was used for comparison between groups; skewed measures were expressed as median (interquartile range) [ M ( Q1, Q3)], and the rank-sum test was used for comparison between groups. Bonferroni correction was used for multiple group comparisons ( P value significance level reduced to 0.017). Quantitative data were compared between groups using the χ2 test or Fisher's exact probability method. Results:There were no statistical differences between the three groups in terms of baseline data at admission (gender, age, etiology, modified CTSI score, degree of pancreatic necrosis, and number of organ failure) ( P>0.05), patients in the EPI group were referred earlier than the other two groups ( P<0.05). In clinical treatment, patients in the IPN group and co-infection group required multiple minimally invasive interventions compared with those in the EPI group ( P<0.05), and the number of patients requiring combined nutritional support, length of intensive care unit stay, and total length of hospital stay were higher in the co-infection group than in the other two groups ( P<0.05). In addition, 360 strains of pathogenic bacteria were cultured in this study, with Gram-negative bacteria being the most common, and patients with SAP were more likely to have EPI in the early stage of disease onset, with bacteremia and respiratory tract infections in the early stage (≤14 d), and bacteremia, urinary tract infections, and catheter-associated infections in the late stage (>14 d). Conclusions:Among patients with SAP, patients in the co-infection group had higher surgical intervention, nutritional support and length of hospital stay than those in the single infection group. It is advisable to prioritize EPI in SAP patients with suspected infections, and the common infectious strains in SAP patients are still predominantly Gram-negative bacteria, and clinicians need to adjust the treatment plan in a timely manner according to the changes in patients′ conditions.
