Síndrome inflamatorio de reconstitución inmunológica (SIRS) en la salud reproductiva / Immune reconstitution inflammatory syndrome (IRIS) in reproductive health

Resumen El embarazo es un proceso que genera grandes cambios inmunitarios en los cuales participan los linfocitos T con respuestas proinflamatorias (Th1/Th17) y antiinflamatorias (Th2/Treg), con la finalidad de mantener el óptimo estado y desarrollo fetal. En la infección por VIH estos ambientes inmunológicos son afectados directamente con el descenso de las células TCD4. El uso de antirretrovirales (ART) ha permitido que las mujeres que viven con VIH puedan disminuir de manera importante la posibilidad de infectar a sus productos con el virus. El embarazo, enfermedades autoinmunes y el uso de ART son factores conocidos para el desarrollo del síndrome inflamatorio de reconstitución inmunológica debido a la recuperación abrupta de la respuesta inmunitaria. En esta revisión describimos parte de estos cambios en el embarazo y puerperio sin patología añadida, además proponemos un posible comportamiento en los perfiles Th1/Th2 en mujeres que viven con VIH que reciben ART y cursan el primer año posparto.

Abstract Pregnancy is a process which generate great immunologic changes with participation of T lymphocytes with inflammatory (Th1/Th17) and anti-inflammatory response (Th2/Treg), with the purpose of maintain the optimum condition and fetal development. In HIV infection this immunological ambient are affected directly due the decrease of T CD4 cells. The use of antiretrovirals (ART) has allowed that women living with HIV can decrease the possibility to infect their newborns with the virus. The pregnancy, autoimmune diseases, and the use of ART are known factors for the progress of immune reconstitution inflammatory syndrome due to the abrupt recovery of immune response. In this review we describe some of these changes during the pregnancy and puerperium without any disease added, furthermore we propose a possible behavior of Th1/Th2 profile in women who live with HIV and receive ART during the first year of postpartum.

AN OBSERVATIONAL STUDY TO EVALUATE THE USEFULNESS OF PROCALCITONIN AS A BIOMARKER OF SEPSIS IN THE EARLY STRATIFICATION OF ADULT PATIENTS ADMITTED TO THE INTENSIVE CARE UNIT WITH SUSPECTED INFECTION

Serum Procalcitonin(PCT) has become useful as a biomarker to assist in the diagnosis of sepsis, as well as related infectious or in?ammatory conditions. It is a soluble protein liberated into the circulation of patients in response to severe systemic in?ammation, in particular by bacterial infection. The aim of this study was to evaluate the usefulness of Procalcitonin as a biomarker of sepsis in the early strati?cation of adult patients admitted to the intensive care unit with suspected infection.Patients are randomly divided into two groups , Group-1: comprising those patients with a bacterial infection (SIRS with Sepsis) and Group -2: comprising patients without a bacterial infection (SIRS without Sepsis). we found that elevated PCT concentrations (> 0.5ng/ml) were detected in a signi?cantly higher proportion of patients with SIRS with sepsis compared to those with SIRS without sepsis so we concluded that PCT is an excellent marker providing the additive effect to improve the predictive power for diagnosing sepsis, for assessing severity of sepsis, and also for predicting the outcome/prognosis.

Evaluation of urine L-FABP Point of care kit in the Philippines as predictive marker of clinical severity of COVID-19 (EPOCH COVID study)

Background@#The search for simple clinical and laboratory markers to help predict the clinical severity of patients presenting with COVID-19 has prompted this study to look at the predictive value of urine L-FABP (Liver Type-Fatty Acid Binding Protein) point-of-care test kit at the initial presentation of COVID-19 patients to the hospital.@*Methods@#The validation study prospectively included 109 consecutive patients with mild to moderate COVID-19, mean age of 52.2 years (range 19-84) presenting at the Emergency Rooms of 4 participating Metro-Manila hospitals from February to April 2021, with available data for analysis for 103 patients. Urine L-FABP POC (Point-of-Care) test and other clinical parameters and the level of severity of COVID-19 were determined at Day 0, Day 4 and Day 7. Computations for Sensitivity, Specificity, Positive and Negative Predictive values and Likelihood ratios were performed.@*Results@#Twenty-three patients tested positive for urine L-FABP, out of the 103 patients analyzed, while 80 tested negative. Of the 23 patients who tested positive for urine L-FABP, 6 has progressed in severity, while 17 did not progressed. Of the 80 patients who tested negative for urine L-FABP, 13 progressed, while 67 did not progressed in severity. Giving a Sensitivity of 31.58%, Specificity of 79.76%, Positive predictive value of 26.09%, Negative predictive value of 83.75%. Combining urine L-FABP and initial clinical parameters like SIRS (Systemic Inflammatory Response Syndrome) criteria to predict progression of severity yielded a higher Specificity of 91.67 % and Negative Predictive value of 84.62%.@*Conclusions@#The study shows the utility of initial urine L-FABP POC test as a negative screening test in triaging adult patients presenting to the ER with mild to moderate COVID-19. Patients at the ER with a negative urine L-FABP test, will most likely not progressed to severe COVID-19. Combining clinical parameters like SIRS Criteria with the urine L-FABP result can increase the negative predictive value.

Prognostic accuracy of qSOFA, NEWS, SIRS criteria for in-hospital mortality among patients with suspected infection presenting to the Emergency Department in a tertiary hospital in Cebu City. A prospective study

Introduction@#Sepsis has been redefined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The quick sepsis-related organ failure assessment (qSOFA) is a simple tool developed to prompt clinicians to consider patients at high risk for poor outcome. Studies have compared its utility with National Early Warning Score (NEWS) and the systemic inflammatory response syndrome (SIRS) criteria. These scoring systems may be utilized to prognosticate illness severity among patients with suspected infection and may be relevant in low- and middle-income settings where laboratory data are not readily available.@*Objective@#To determine and compare the accuracy of qSOFA, NEWS, and SIRS criteria in predicting in-hospital mortality in patients suspected to have infection presenting at the emergency department (ED)@*Methods@#This is a prospective cohort study. Patients ≥18 years old with suspected infection admitted to the ED between June 2018 to July 2018 were included in the study. SIRS, NEWS, and qSOFA scores were collected at presentation and patients were followed up until expired or discharged.@*Results@#A final population of 213 were included in the study with a mean age of 47 years (SD 21.2) and 124 (58.2%) females. The most common site of infection was respiratory (33.8%). Twelve patients (5.6%) died in-hospital. Among patients with qSOFA≥2, mortality rate was at 38% vs 3.5% for qSOFA<2. Specificity for mortality was highest for qSOFA (96%). Sensitivity was highest for SIRS (75%). SIRS, qSOFA, and NEWS had no significant difference in predicting in-hospital mortality with an area under the receiver operating curve of 0.659, 0.711, 0.711 respectively.@*Conclusion@#SIRS, qSOFA, and NEWS have similar prognostic accuracy to predict mortality but have limited use when applied individually which brings into question the sole utility of qSOFA despite its high specificity. It is reasonable to further validate or develop new scoring systems with higher predictive accuracy appropriate across different populations.

Síndrome postimplantación en la reparación aórtica endovascular / Post implantation syndrome in endovascular aortic repair

Resumen Introducción: El síndrome postimplantación es un trastorno frecuente, producido en el posoperatorio inmediato posterior al tratamiento endovascular de la enfermedad aórtica, caracterizado por la presencia de anorexia, dolor lumbar, leucocitosis, fiebre y elevación de la proteína C reactiva, asociado ocasionalmente a disminución del recuento de plaquetas o alteración de la coagulación. Objetivos: Determinar la incidencia y morbilidad asociada al síndrome postimplantación, posterior a la reparación endovascular de la patología aórtica. Material y Métodos: Estudio observacional y descriptivo, donde se analiza la presencia del síndrome post implantación en pacientes sometidos a Reparación endovascular torácica aórtica (TEVAR) y Reparación endovascular de aneurisma (EVAR), durante un período de 10 años (2009 al 2019), en el Hospital Dr. Eduardo Pereira de Valparaíso, Chile. Resultados: Se incluyeron 112 reparaciones endovasculares, 72,32% correspondientes a EVAR y 27,68% a TEVAR, incidencia del síndrome post implantación (17,85%), factores de riesgo asociados: edad ≤ 75 años, uso de endoprótesis compuesta por poliester, recubrimiento aórtico ≥ 20cm y tiempo quirúrgico >180 min; (p < 0,05), evidenciando en este grupo de pacientes mayor readmisión, estancia hospitalaria y morbilidad cardiovascular (p < 0,05). Discusión: El síndrome post implantación conduce a una recuperación posoperatoria más exigente, aumentando la morbilidad cardiovascular, readmisión y estancia hospitalaria, con los correspondientes riesgos y costos asociados, en consecuencia podría considerarse una complicación de la reparación aórtica endovascular. Conclusión: La respuesta inflamatoria puede ser intensa posterior a la reparación endovascular de la aorta, el grupo de pacientes que desarrolla este síndrome, amerita una estrecha vigilancia, con énfasis durante el primer mes de post operatorio.

Introduction: Postimplantation syndrome is a common disorder, produced in the immediate postoperative period after endovascular treatment of aortic disease, characterized by anorexia, thoracic or low back pain, leukocytosis, fever and elevation of C-reactive protein, occasionally associated with decreased platelet count or coagulation disorders. Aim: To assess postimplantation syndrome after endovascular aortic repair. Material and Methods: This is an observational, and descriptive study; we analyze the presence of postimplantation syndrome, in 112 successive endovascular repairs of the thoracic and abdominal aorta, over a period of 10 years (2009 to 2019), in the Hospital Dr. Eduardo Pereira in Valparaíso, Chile. Results: 112 endovascular repairs were performed, 81 cases (72.32%) corresponding to EVAR and 31 cases (27.68%) to TEVAR, incidence of post-implantation syndrome was 17.85%. Associated risk factors were age ≤ 75 years, use of polyester stent grafts, aortic covered ≥ 20 cm, surgical time ≥ 180 min, (p < 0.05). As a consequence, in this group of patients, there were associated with greater readmission rates, hospital stay rates and cardiovascular morbidity (p < 0.05). Discussion: The post-implantation syndrome leads to an increase in cardiovascuar morbidy hospital stay rates and a slower postoperative recovery, with the corresponding associated risks and costs, therefore it could be considered a complication of endovascular aortic repair. Conclusion: The inflammatory response after endovascular repair of the aorta, may be intense in some patients, the group of patients who develop this syndrome deserve close monitoring, with emphasis during the first month after surgery.

SIRS y qSOFA como Predictores de Mortalidad en Sepsis Pediátrica

Resumen Introducción: La sepsis pediátrica continúa siendo una causa importante de mortalidad en países de bajos y medianos ingresos, su reconocimiento temprano en emergencias requiere del uso de criterios que nos permitan predecir anticipadamente la gravedad del paciente. Objetivo: nuestro estudio pretende comparar los criterios de SIRS y qSOFA en cuanto a su capacidad discriminatoria en mortalidad en sepsis pediátrica. Métodos: realizamos un estudio multicéntrico, prospectivo en servicios de emergencias incluyendo niños con sospecha de sepsis subsecuentemente ingresados a UTIP, en los cuales se evaluaron los puntajes en SIRS y qSOFA comparándolos con los resultados al egreso. Resultados: se enrolaron 64 pacientes, admitidos en estadios de Sepsis (19%), Shock Séptico (20,6%) y con Disfunción Multiorgánica (60,4%), con una mortalidad respectivamente de 9,5%, 14,3% y 76,2%; en 33,9% de los casos se pudo rescatar algún germen. Evaluando los criterios SIRS vemos que la ausencia de ellos se asocia con mayor sobrevivencia (p=0,044; OR 0,618: IC95% 0,5020,761), Por otro lado, 2 o más criterios qSOFA se asocia con mayor mortalidad (p=0,047; OR 3,52: IC95% 1,090-11,371). Conclusión: ambos criterios utilizados para definir sepsis en pediatría demostraron su utilidad, el uso del score qSOFA dada a su estrecha relación con la mortalidad puede emplearse para anticipar alteraciones orgánicas potencialmente mortales.

Abstract Introduction: Pediatric sepsis continues to be one of the main causes of mortality in low and middle-income countries, its early recognition in emergencies requires the use of criteria that allow us to predict the severity of the patient. Objective: our study aims to compare the SIRS criteria and qSOFA regarding its discriminatory capacity in mortality in children with sepsis. Methods: a prospective multicenter study was carried out in emergency services enrolling children with suspected sepsis subsequently admitted to the PICU, in which the scores in qSOFA and SIRS were evaluated comparing them with the results at hospital discharge. Results: 64 patients were enrolled, admitted in emergency in Sepsis (19%), Septic Shock (20.6%) and with Multiple Organ Dysfunction (60.4%) stage, with a mortality respectively of 9.5% and 14.3% and 76.2%; germ could be rescued in 33.9% of the cases; Evaluating the SIRS criteria, we see that the absence of them is associated with lower mortality (p = 0.044; OR 0.618: 95% CI 0.502-0.761); otherwise, 2 or more qSOFA criteria are associated with higher mortality (p = 0.047 ; OR 3.52: 95% CI 1.090-11.371). Conclusion: both criteria used to define sepsis in pediatrics demonstrated their usefulness, the use of the qSOFA score given its close relationship with mortality can be used to anticipate life-threatening organ alterations.

SIRS o no SIRS: ¿es esa la infección? Una revisión crítica de los criterios de definición de sepsis / SIRS or not SIRS: Is that the infection? A critical review of the sepsis definition criteria

Resumen El enfoque moderno de la sepsis se ha centrado en la creación de consensos globales que utilizan distintos criterios para pesquisarla en forma precoz, con el fin de disminuir la morbimortalidad asociada a ella. Hasta la aparición del tercer y último consenso de adultos (Sepsis-3), el síndrome de respuesta inflamatoria sistémica (SIRS) fue el pilar diagnóstico utilizado por defecto en todas las edades. En Sepsis-3 se decidió retirar el SIRS, lo que generó un debate internacional sobre la oportunidad de dicho cambio. Esta revisión narrativa desarrolla la historia de las distintas definiciones de sepsis centradas en SIRS, las fortalezas, las debilidades y la pertinencia de los distintos elementos que ocasionaron el debate. Dada la ausencia de actualizaciones pediátricas en Sepsis-3, se hace especial énfasis en las implicaciones para las futuras definiciones de sepsis en esta etapa de la vida.

Abstract The modern approach to sepsis has focused on creating a global consensus with different criteria to early investigate it in order to reduce the morbidity and mortality associated with this complex entity. Until the third and last consensus of adults (Sepsis-3), the systemic inflammatory response syndrome (SIRS) was the diagnostic pillar used by default for all ages. In Sepsis-3, it was decided to withdraw the SIRS, which generated an international debate about the timing of such change. This narrative review develops the history of the different definitions of sepsis focused on SIRS, their strengths and weaknesses, and the relevance of the different elements that caused the debate. Given the absence of pediatric updates in Sepsis-3, a particular emphasis is placed on the implications for future definitions of sepsis at this stage of life

Systemic inflammatory response syndrome as a predictor of poorer outcomes in diabetic foot infection: a prospective analytical study

Background: This study was done to diagnose the severity of infection in a group of hospitalized diabetic foot infection (DFI) patients based on the presence or absence of systemic inflammatory response syndrome (SIRS) and compare the outcomes.Methods: This was a single-center cohort study, in which 50 consecutive DFI patients having SIRS and 50 consecutive patients not having SIRS were included. Patients were followed for the duration of the hospital stay; parameters for glycaemic control, minor and major amputation, microbial culture, duration of hospital and ICU stay and mortality was recorded.Results: The relative risk of major amputation among the patients of DFI who presented with SIRS was 2.66 times higher compared to who was not having SIRS at presentation (95% CI, 1.56-4.55). The presence of polymicrobial infection also had a statistically significant association with the incidence of major amputation. The duration of hospital stay was ~9.5 days longer in the DFI patients who presented with SIRS compared to who was not having SIRS at the time of presentation [8.00 (4.00-20.50) days versus 17.50 (10.75-38.25) days]. DFI patients with SIRS required a significantly prolonged ICU.Conclusions: SIRS can be used as objective criteria to predict poorer outcomes in the diabetic foot infection patient and also to classify it.

Sepsis en Cirugía / Sepsis in Surgery

Resumen La sepsis constituye una causa frecuente de muerte por lo que es muy importante el diagnóstico precoz para conseguir un manejo oportuno y eficiente. Las definiciones y consensos han ido sufriendo modificaciones a lo largo del tiempo por lo que el equipo médico quirúrgico debe estar atento a estos cambios y debe mantenerse en constante actualización. El consenso de Sepsis-3, propone el uso del qSOFA y SOFA con el fin de mejorar la especificidad del reconocimiento de pacientes de mayor gravedad; no obstante, esto se logra a expensas de una menor sensibilidad, es por esto que los criterios clásicos de SIRS deben seguir utilizándose ante la sospecha de sepsis. Es clave la identificación temprana de los pacientes para que el resultado de las medidas a tomar sea el óptimo. La sepsis quirúrgica sigue siendo un cuadro clínico difícil de reconocer y manejar, es una urgencia que requiere medidas iniciales durante la primera hora de sospecha por lo que es transcendental para el cirujano conocer estas medidas, para poder planificar una posible cirugía de urgencia con el respaldo médico adecuado, según corresponda. El objetivo de esta revisión es que el cirujano y el equipo médico actualicen los cambios de los consensos de sepsis en cuanto al diagnóstico y al manejo bajo una mirada crítica y conozcan también el enfrentamiento adecuado de una sepsis quirúrgica para, de esta manera, mejorar la sobrevida de nuestros pacientes.

Sepsis constitutes a frequent cause of death, early diagnosis is essential to achieve proper management. Definitions and consensus have undergone modifications over time, so the surgical and medical team must be aware of these changes and must be constantly updated. The consensus of Sepsis-3 proposes the use of qSOFA and SOFA in order to improve the specificity of the recognition of patients with greater severity; however, this is achieved at the expense of lower sensitivity, so that the standard SIRS criteria should continue to be used when sepsis is suspected.The early identification of patients is very important to optimize the handling of the medical team. Surgical sepsis remains a difficult clinical picture to recognize and manage. It is an emergency that requires initial actions during the first hour of suspicion. By this it is important for the surgeon to know these actions that allow him or her to plan a possible emergency surgery when appropriate with adequate medical support. The objective of this update is for surgeon and medical team to know the changes in sepsis consensus regarding diagnosis and management under a critical view, as well as to know the therapeutic approach of a surgical sepsis to improve the survival of our patients.

Antimicrobial utilization pattern in Systemic Inflammatory Response Syndrome positive septicemia: a prospective study in an apex hospital in South Delhi

Background: Despite significant advances in critical care, mortality and morbidity in severe sepsis and septic shock remain high, this may be explained by the fact that in sepsis bacterial infection triggers the innate immune response, setting in motion a cascade of pro-inflammatory and anti-inflammatory cytokines leading to what we recognize as the systemic inflammatory response syndrome (SIRS). It has been thought that this self-propagating cascade drives the progression to severe sepsis and septic shock with increasing degrees of cellular injury and end-organ dysfunction, therefor early initiation of empirical antimicrobial agent is crucial and life-saving atleast in high risk patient. This study aimed to see the outcome (recover or mortality) of patients diagnosed by using SIRS criteria.Methods: Total of 105 patients of suspected sepsis fulfilling SIRS criteria (SIRS ?2), were included in study. Study population were administered appropriate empirical antimicrobial depending on the source of infection and followed till the final outcome (complete recovery or death).Results: Out of 105 patients included in study based on SIRS criteria, 87 (82.85%) were confirmed to be having septicemia on further evaluation. In majority of patient primary source of infection were respiratory tract (44.76%) and most commonly employed and effective empirical antimicrobial were a combination piperacillin with tazobactum and amikacin (40%). 92.39% patients recovered with empirical antimicrobial, with total in-hospital mortality rate of 7.61%.Conclusions: Early initiation of appropriate antimicrobial by using SIRS as an indicator for the early diagnosis of septicemia is crucial in the management of septicemia and prevention of development of severe sepsis, septic shock.

Comparison of diagnostic and prognostic value of serum procalcitonin and serum lactate in pediatric sepsis

Background: The clinical manifestations of sepsis are highly variable. The signs of both infection and organ dysfunction may be subtle, and thus the most recent international consensus guidelines provide a long list of warning signs of incipient sepsis. Lactic acid, which is a by-product of anaerobic metabolism, can be used as a marker of tissue hypoperfusion. It is being used widely. Procalcitonin has more recently been studied in children.Methods: Totally 60 Children admitted with Septic Shock in PICU between Ages 3 Months to 12 Years were assessed for Serum Lactate & Serum Procalcitonin levels. Evaluation of the biomarkers was done on individual and combinational basis using receiver operating characteristics curve.Results: Out of 60 children, male were 40, female were 20 children. In stage-1 serum lactate' level was 47.83 (mg/dl) sensitivity is about 35.63 and specificity was 63.82' off p-value <0.065**.In stage -2 serum procalcitonin was 49.62 (mg/dl) sensitivity is about 37.77 and specificity was 69.28' off p-value <0.549**.In stage -3 serum procalcitonin was 52.89 (mg/dl) sensitivity is about 41.63 and specificity was 73.89' off p-value <0.651**Conclusions: Early recognition of risk factors will help in timely appropriate therapy and thereby will help in reducing mortality and morbidity in pediatric septic shock. The results suggest that PCT is valid for auxiliary diagnosis of septic conditions in children and used as an indicator of the severity of patients.

Resumen: Introducción: La detección temprana de sepsis es fundamental para disminuir la mortalidad de este padecimiento. Hasta el momento, ninguna escala clínica ni biomarcador ha sido útil en su diagnóstico y detección precoz. Los niveles de actividad de la acetilcolinesterasa se han propuesto como un biomarcador muy prometedor para la detección de sepsis y choque séptico. Objetivo: Estudiar la utilidad de los niveles de acetilcolinesterasa en el diagnóstico de sepsis. Material y métodos: Estudio observacional y prospectivo, en pacientes de la Unidad de Cuidados Intensivos del Hospital San Ángel Inn Universidad con diagnóstico de inestabilidad hemodinámica, clasificados con presencia o no de sepsis, tomándose niveles de acetilcolinesterasa al ingreso. Resultados: Se evaluaron 44 pacientes, 27% con sepsis. Los valores de acetilcolinesterasa tuvieron validez diagnóstica para predecir sepsis (AUC: 0.852 IC 95%: 0.726-0.977, p < 0.001), con un punto de corte de 3,956 U/L, sensibilidad = 81%, especificidad = 75%. El valor de neutrófilos con corte < 74% también tuvo valor predictor de sepsis (AUC: 0,710 IC 95%: 0,512-0,907, p = 0.034) sensibilidad = 75%, especificidad = 75%. Conclusiones: En pacientes con inestabilidad hemodinámica con niveles de acetilcolinesterasa mayores de 4,000 U/L se descarta sepsis como causa de choque.

Abstract: Introduction: Early detection of sepsis is essential to reduce mortality from this condition. So far, no clinical scale or biomarker has been useful in its diagnosis and early detection. Levels of acetylcholinesterase activity have been proposed as a very promising biomarker for the detection of sepsis and septic shock. Objective: To study the usefulness of acetylcholinesterase levels in the diagnosis of sepsis. Material and methods: Observational and prospective study in patients of the Intensive Care Unit of the Hospital San Ángel Inn Universidad with diagnosis of hemodynamic instability, classified with or without sepsis, taking acetylcholinesterase levels at admission. Results: 44 patients were evaluated, 27% with sepsis. The acetylcholinesterase values ​​presented a normal distribution and had diagnostic validity to predict sepsis (AUC: 0.852 95% CI: 0.726-0.977, p < 0.001), with a cut-off value of < 3,956 U/L, sensitivity = 81%, specificity = 75%. The value of neutrophils with a cut < 74% also had a predictive value of sepsis (AUC: 0.710 95% CI: 0.512-0.907, p = 0.034) sensitivity = 75%, specificity = 75%. Conclusions: In patients with hemodynamic instability with acetylcholinesterase levels greater than 4,000 U/L, sepsis is ruled out as the cause of shock.

Conclusões: Em pacientes com instabilidade hemodinâmica com níveis de acetilcolinesterase superiores a 4,000 U/L a sepse é descartada como causa de choque.

The values of SOFA score, qSOFA score and SIRS criteria in predicting the prognosis of adult patients with suspect infection / 中华急诊医学杂志

Objective To investigate the clinical values of SOFA score,qSOFA score and SIRS criteria in predicting the prognosis of patients with suspected infection in the emergency department.Methods From January 2015 to April 2017,487 patients aged over 18 years were suspected to be infected and admitted to hospital.SOFA,qSOFA,and SIRS scores were calculated.The mortality and the requirement of ICU treatment were used as prognostic factors for evaluating the validity of each score.The prognostic value of each scoring system was evaluated by the area under the receiver operating characteristic curve (AUROC).Results In 487 patients,the hospital mortality rate was 4.9％,and requirement of ICU treatment rate was 17％.SOFA score predicting hospital mortality and requirement of ICU treatment (AUROC 0.905) were superior to other scores (qSOFA-WBC:AUROC 0.778,qSOFA:AUROC 0.769,SIRS:AUROC 0.64).Compared with the SIRS criteria,patients with a score of ＞1 had higher qSOFA scores (94.47％),but lower sensitivity (44.86％);although SIRS criteria had a higher sensitivity (77.57％),they were less specific (42.63％).When qSOFA was added to the condition of leukocyte abnormalities (＜4× 109/L or ＞ 10× 109/L),the prognosis was improved and the sensitivity and specificity for prognosis were 73.83％ and 71.84％ (qSOFA-WBC score,＞1),respectively.In patients with qSOFA-WBC score,only 6 patients (negative predictive value of 94.2％) died or required ICU treatment.Conclusion The SOFA score is superior to qSOFA and SIRS in predicting the prognosis of patients with suspect infection,and qSOFA-WBC is superior to qSOFA and SIRS in predicting low risk.

Risk factors associated with systemic inflammatory response syndrome after percutaneous nephrolithotomy in China:A Meta-analysis / 中国内镜杂志

Objective To explore the risk factors of systemic inflammatory response syndrome crisis (SIRS) after percutaneous nephrolithotomy (PCNL) in China. Methods Databases of CNKI, CBM, WanFan and VIP were searched to retrieve studies about systemic inflammatory response syndrome after percutaneous nephrolithotomy to October, 2016. Results 18 studies involving 5,323 patients were included. The results of meta-analysis showed that:a) univariate analysis indicated that renal insufficiency [O(R) =2.78, 95%CI (1.96 to 3.95), P = 0.000], preoperative positive urine culture [O(R) = 3.41, 95%CI (1.89 to 6.15), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 3.78, 95%CI (3.02 to 4.72), P = 0.000], diabetes mellitus [O(R) = 2.14, 95%CI (1.33 to 3.45), P = 0.002], pelvic positive urine culture [O(R)= 5.14, 95%CI (2.46 to 10.73), P = 0.000] and operation time ≥120 min [O(R) = 2.31, 95%CI (1.40 to 3.82), P = 0.001] were the risk factors of SIRS; b) multivariate analysis showed that, preoperative positive urine culture [O(R) = 6.83, 95%CI (2.82 to 16.57), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 5.43, 95%CI (3.51 to 8.41), P = 0.000], diabetes mellitus [O(R) = 2.85, 95%CI (1.45 to 5.58), P = 0.002], pelvic positive urine culture [O(R) = 4.30, 95%CI (1.30 to 14.21), P = 0.020] and operation time ≥120 min [O(R) = 2.72, 95%CI (1.62 to 4.59), P = 0.000] were the independent risk factors of MCAT. Conclusion The independent risk factors of SIRS for patients after PCNL are diabetes mellitus, preoperative positive urine culture, preoperative routine urine leucocyte positive, pelvic positive urine culture and operation time. However, due to the quantity and low quality of the included literature, the conclusion needs the support from high quality studies.

The results of meta-analysis showed that:a) univariate analysis indicated that renal insufficiency [O(R) =2.78, 95%CI (1.96 to 3.95), P = 0.000], preoperative positive urine culture [O(R) = 3.41, 95%CI (1.89 to 6.15), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 3.78, 95%CI (3.02 to 4.72), P = 0.000], diabetes mellitus [O(R) = 2.14, 95%CI (1.33 to 3.45), P = 0.002], pelvic positive urine culture [O(R)= 5.14, 95%CI (2.46 to 10.73), P = 0.000] and operation time ≥120 min [O(R) = 2.31, 95%CI (1.40 to 3.82), P = 0.001] were the risk factors of SIRS; b) multivariate analysis showed that, preoperative positive urine culture [O(R) = 6.83, 95%CI (2.82 to 16.57), P = 0.000], preoperative routine urine leucocyte positive [O(R) = 5.43, 95%CI (3.51 to 8.41), P = 0.000], diabetes mellitus [O(R) = 2.85, 95%CI (1.45 to 5.58), P = 0.002], pelvic positive urine culture [O(R) = 4.30, 95%CI (1.30 to 14.21), P = 0.020] and operation time ≥120 min [O(R) = 2.72, 95%CI (1.62 to 4.59), P = 0.000] were the independent risk factors of MCAT. Conclusion The independent risk factors of SIRS for patients after PCNL are diabetes mellitus, preoperative positive urine culture, preoperative routine urine leucocyte positive, pelvic positive urine culture and operation time. However, due to the quantity and low quality of the included literature, the conclusion needs the support from high quality studies.

Role of Procalcitonin and C-reactive protein in differentiating culture negative bacterial sepsis and systemic inflammatory response

Background: It is very important to distinguish between non-infectious systemic inflammatory response (SIRS) and culture negative sepsis as the management of the two conditions is different this often creates diagnostic challenge in day to day practice. The aim of present study is to investigate the diagnostic accuracy of serum PCT and CRP to differentiate between culture negative bacterial sepsis and non-infective SIRS. We have also studied their diagnostic efficacy in culture-positive sepsis. Materials and methods: 178 cases who were admitted in acute medical care unit in tertiary care centre, were included in the study. The cases were divided into three groups. Group I (culture positive sepsis) patients with positive microbial culture and 2 or more signs of sepsis. Group II (culture negative sepsis) includes patients with 2 or more sign of SIRs and clinical suspicion of infection with negative culture result. Group III (non-infective SIRs) includes patient with 2 or more sign of SIRS without evidence of any infection. Samples were collected for blood culture, differential count, PCT and CRP along with other routine investigation. The diagnostic performance of PCT and CRP was demonstrated with ROC curve analysis. Results: The median Procalcitonin was approximately 9 fold higher in culture negative group compared to non-infective SIRS and it was statistically significant (P<0.01) whereas CRP showed Siraj Ahmed Khan, Iyyapu Krishna Mohan, Bhavya Sirivelu, Rachel Jacob. Role of Procalcitonin and C-reactive protein in differentiating culture negative bacterial sepsis and systemic inflammatory response. IAIM, 2017; 4(3): 24-29. Page 25 only 2-3 fold increase between these groups. ROC curve analysis for PCT and CRP between culture negative and SIRS groups for prediction of systemic infection were performed. The area under the curve for PCT and CRP were 0.986 and 0.785 respectively. Conclusion: Biomarkers such as PCT and CRP are strongly associated with infection likelihood and sepsis and they can serve as useful adjuncts to routine clinical information. These markers were also able to distinguish between patients with non-infective SIRS and sepsis.

The role of heparin-binding protein in the diagnosis and prognosis of sepsis syndrome in pediatric patients at the Philippine Children's Medical Center

@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> The burden of sepsis is global despite measures to improve its prompt recognition. However, there is no single reliable parameter for its early detection. Heparin-binding protein (HBP) is a new and promising biomarker for sepsis. Presently, there are no published reports in children apart from a limited study on UTI.</p><p style="text-align: justify;"><strong>OBJECTIVE:</strong> To evaluate the role of HBP as a diagnostic tool and prognostic marker of sepsis syndrome among pediatric patients.</p><p style="text-align: justify;"><strong>METHODS:</strong> This prospective cohort study enrolled pediatric patients who were categorized as SIRS or sepsis syndrome. HBP assay was determined on Day1. Likewise, blood culture was taken. A 7-day observation period using PELOD scoring was done. Final category as SIRS or sepsis syndrome was done on Day7. Statistical analysis was done to know relationship of HBP level to SIRS and sepsis.</p><p style="text-align: justify;"><strong>RESULTS:</strong> 106 patients were included in this study. There was statistical significance in the correlation of HBP assay with presence of growth in blood culture and toxic granulations, length of ventilator support, and development of complications including mortality. The cutoff point was >125ng/mL. Sensitivity and specificity for HBP in sepsis syndrome were 98.31% and 97.87% respectively. Positive predictive value was 98.3%. Negative predictive value was 97.9%. Positive likelihood ratio was 46.2. Negative likelihood ratio was 0.017. Risk ratio was 47.6. Subjects with HBP level of >125 ng/mL had 47.6 times the risk of having sepsis syndrome as compared to those with level</p><p style="text-align: justify;"><strong>CONCLUSION & RECOMMENDATIONS</strong>: Elevated HBP level is a useful diagnostic and prognostic marker for childhood sepsis syndrome. Determination of HBP levels at different time intervals within a longer observation period may give a more accurate description of subject's clinical improvement or progression to MODS or mortality.</p>

Prognostic value of procalcitonin in patients with acute paraquat intoxication / 中华急诊医学杂志

Objective To study the prognostic value of procalcitonin (PCT) level in the outcome of patients with paraquat poisoning (PQ).Methods The clinical data of 128 patients with acute PQ admitted to emergency department were collected from March 2013 through March 2014.The patients were divided into two groups:the death group and the survival group (survival of 28 days).Poisoning doses,urine concentration of PQ,time elapsed from poisoning to admission,and time elapsed from poisoning to gastrolavage were documented.And on the 1 st day,the 3rd day and the 7th day after poisoning,serum PCT were detected.The level of PCT was used to investigate the prognostic values in patients with acute PQ in the death group and survival group.Results Of 128 cases,72 (56.3％) survived and 56 died in 28 days.Among them,the level of PCT increased to some extent in the first day in 90 cases,and 48 patients died.According to trend analysis,the levels of PCT in death group on the 1st day,the 3rd day and the 7th day after PQ were significantly higher than those in survival group [ld:(0.96 ±0.13) vs.(0.08 ±0.01),3d:(1.12 ±0.14) vs.(0.28 ±0.05),7d:(1.22 ±0.14) vs.(0.20 ±0.03),P ＜0.01].There was a trend of escalating PCT levels in death group,whereas the PCT level reached the peak on the 3st day and decreased gradually in the following days in survival group.The early PCT level was obviously related to poisoning doses,urine concentration,CRP,WBC,ALT,CR (the coefficient of association were 0.794,0.723,0.724,0.332,0.700,0.414,respectively,P＜0.01).Conclusions The serum level of PCT increased in patients with acute PQ was significantly positively correlated with the oral dose and urine concentration of paraquat,and it can be used as an indicator for PQ severity.There is important clinical significance in detecting the change of serum level of PCT for estimating the condition of patients and evaluating the prognosis.

Key Points for Curbing Cardiopulmonary Bypass Inflammation

PURPOSE: Cardiopulmonary bypass (CPB) procedures are thought to activate systemic inflammatory reaction syndrome (SIRS). Strategies to curb systemic inflammation have been previously described. However, none of them is adequate, since "curbing" the extent of the inflammatory response requires a multimodal approach. The aim of the present mini-review is to discuss the main key points about the main principles in cardiopulmonary bypass curbing inflammation. METHODS: No systematic literature search (MEDLINE) and extracted data from the accumulated experience of the authors. The preconceived idea of an association between severe inflammation and coagulation disorders is reviewed. Also, some fundamental concepts, CPB inflammatory biomarkers, the vasoplegic syndrome and the need forindividual CPB protocols for children, diabetes and old patients, are discussed. CONCLUSION: The ways in which surgical technique (atraumatic vein harvest, biocompatibility and shear resistance of the circuit, monitoring, minimizing organ ischemia, minimal cross-clamping trauma, and blood management) are thought to curb SIRS induced by CPB and affect positively the patient outcome.Improved patient outcomes are strongly associated with these modalities of care, more than single or combinatorial drug strategies (aprotinin, tranexamic acid, pentoxifylline) or CPB modalities (minicircuits, heparin-coated circuits, retrograde autologous prime).
