    Full Text Available Introducción La sepsis es la principal causa de mortalidad en unidades de cuidado crítico, factores de riesgo de mortalidad como la edad, el género y las escalas de severidad han sido estudiados. En nuestra población de estudio las otras complicaciones durante la hospitalización fueron las más relacionadas con el descenlace. Materiales y métodos Estudio de cohorte de 150 pacientes admitidos a unidad de cuidado critico de cuatro unidades del área metropolitana de Bucaramanga, con diagnostico de sepsis severa o choque séptico fueron estudiados mediante un cuestionario sobre variables socio-económicas, clínicas y microbiológicas. Se realizó análisis bivariado con pruebas t de student y chi cuadrado. El análisis multivariado mediante regresión de cox con el tiempo al evento como variable de descenlace. Resultados Los pacientes sobrevivientes tuvieron un promedio de edad de 64 años y los no sobrevivientes de 67 años, sin que se demostraran diferencias estadísticas entre los dos grupos de pacientes. No se encontraron diferencias en cuanto al género. El factor de riesgo más importante asociado a mortalidad por sepsis fueron las complicaciones durante la hospitalización, incluso luego de ajustar por el puntaje sofá inicial, el sitio de infección y los indicadores de respuesta inflamatoria como la hiperlactatemia e hiperbilirrubinemia. Conclusiones Se encontraron tres modelos de riesgo para mortalidad por sepsis con otras complicaciones durante la hospitalización como el factor de riesgo más relevante y el control glicemico como el factor de protección más importante.

    2006-09-01

    Full Text Available El metapneumovirus humano (hMPV es un nuevo agente causal de infección aguda del tracto respiratorio, recientemente reportado tras su hallazgo en niños, jóvenes, adultos y ancianos. Las manifestaciones clínicas producidas por el hMPV son indistinguibles de aquellas provocadas por los virus respiratorios clásicamente conocidos, y varían desde infección asintomática hasta neumonía complicada. Por otro lado, se han descrito casos de exacerbación de asma bronquial asociados a la infección con hMPV. En este trabajo se describe el caso de un niño hospitalizado que presentó una crisis asmática bronquial severa con sospecha de una infección viral asociada. Por el test de inmunofluorescencia indirecta no se detectaron virus sincicial respiratorio (VSR, adenovirus, virus influenza a - b ni virus parainfluenza 1, 2 y 3. En un intento por detectar la presencia de hMPV, se realizó una RT-PCR para la amplificación de los genes N y F con resultado positivo. Conforme a nuestro conocimiento, esta sería la primera descripción de un caso de exacerbación de asma asociado a hMPV en nuestra región. Los resultados de este estudio serían similares a los reportados por otros autores, quienes postulan que, a semejanza de lo que ocurre con el VSR, una infección por hMPV puede gatillar una enfermedad respiratoria crónica, como el asma.Human Metapneumovirus (hMPV is a recently reported agent of acute infection in the respiratory tract. It has been found in children as well as in young adults and elders. The clinical manifestations produced by hMPV are indistinguishable from those by common respiratory virus, and can evolve from asymptomatic infection into severe pneumonia. On the other hand, some authors have described cases of bronchial asthma exacerbation associated with hMPV infection. In this work we report a case of a child who presented a severe bronchial asthmatic crisis with a suspected viral associated infection. Immunofluorescence tests

    Full Text Available Antecedentes/Objetivo : Las enfermedades cardiovasculares y la depresión son comunes y, muchas veces, coexistentes empeorando la calidad de vida. Además, existen trastornos de funciones cognitivas omnipresentes en pacientes con insuficiencia cardiaca. Se obser - van deficiencias de distinto nivel de severidad en varios dominios cognitivos. Asimismo, en la depresión existen problemas cognitivos que podrían perjudicar el funcionamiento cotidiano, obstaculizar la adaptación a la enfermedad y empeorar los pronósticos. El objetivo de este trabajo fue evaluar la relación entre calidad de vida, intensificación de trastornos depresivos y trastornos de ciertos aspectos de las funciones ejecutivas y me - moria en pacientes con insuficiencia cardiaca grave y estable. Método : Los estudios se realizaron en un grupo de 50 pacientes con insuficiencia cardiaca grave y estable, y otro de 50 pacientes con enfermedad coronaria, pero sin insuficiencia cardiaca. Resultados : Los resultados de las pruebas cognitivas son notablemente peores en el grupo con insufi - ciencia cardiaca en comparación con el grupo control. Se observó una calidad de vida considerablemente peor y unos resultados significativamente más altos en la prueba BDI- II. No se demostró que los trastornos cognitivos influyeran en el empeoramiento de la calidad de vida. Sin embargo, se observó que los síntomas de depresión influían en la calidad de vida. Conclusiones : El factor que afecta significativamente la calidad de vida es la intensificación de los síntomas depresivos.

    La Inmunodeficiencia Severa Combinada (IDSC es una enfermedad
    de origen genético, que se puede heredar de forma autosómica
    recesiva o ligada al cromosoma X. La IDSC se caracteriza por un
    defecto en el número y la diferenciación de los linfocitos T y NK. Los
    individuos afectados desarrollan diarrea crónica, infecciones persistentes y severas como neumonía, septicemia e infecciones fúngicas.
    Estos pacientes presentan retardo en el crecimiento y pueden morir a
    temprana edad si no se realiza una terapia de corrección genética o un
    trasplante de células hematopoyéticas. Las mutaciones responsables
    de la IDSC comprometen principalmente el gen de la cadena gama

    Full Text Available INTRODUCCIÓN. El objetivo de esta investigación fue determinar los factores de riesgo asociados al fallo renal agudo (FRA en un grupo de niños con sepsis grave atendidos entre enero del 2004 y diciembre del 2008. MÉTODOS. Se realizó un estudio observacional y analítico con una muestra de 171 pacientes. Se constituyeron dos grupos: el de estudio, integrado por 38 pacientes con estado de choque séptico o disfunción múltiple de órganos (DMO y FRA, y un grupo control, conformado por 133 niños en igual estadio de sepsis pero con función renal normal. Se revisaron las historias clínicas y se tuvieron en cuenta variables epidemiológicas, factores de riesgo de FRA y evolución de los casos. RESULTADOS. La incidencia de FRA fue del 22,2 %, y aunque disminuyó considerablemente en los 3 últimos años del estudio, la mortalidad fue del 42,1 %, mayoritariamente en el DMO (89,5 %. Se encontró dependencia entre la insuficiencia renal y la respuesta diurética no adecuada a la fluidoterapia (51,2 %, la inestabilidad hemodinámica por más de 24 h (46,5 %, la disfunción miocárdica (43,3 % y el uso de medicamentos nefrotóxicos (42,8 %. CONCLUSIONES. La respuesta diurética no adecuada a la fluidoterapia, la inestabilidad hemodinámica por más de 24 h, la disfunción miocárdica y el uso de medicamentos nefrotóxicos incrementan el riesgo de FRA en la sepsis grave, la cual duplica la mortalidad en relación con los pacientes que conservan la función renal. No obstante, la prevención de las formas graves de sepsis y un tratamiento adecuado de ésta disminuyen la incidencia de FRA.INTRODUCTION: The aim of present research was to determine the risk factor associated with the acute renal failure (ARF in a group of children with severe sepsis seen between January, 2004 and December, 2008.

    Full Text Available La lepra es una patología infecciosa de carácter crónico, caracterizada por un amplio compromiso cutáneo, asociado a neuropatía, con bajas tasas de mortalidad, pero con un alto índice de discapacidad. Es causada por la infección por el bacilo, Mycobacterium leprae. A pesar que se conoce desde la antigüedad se considera un problema persistente de salud pública en áreas subtropicales donde es endémica. Su mecanismo de transmisión, es por medio de gotitas respirato-rias. Su espectro clínico es muy variado, depende de la forma en que el sistema inmunitario del huésped reacciona frente al agente infeccioso, por lo que se reconocen los polos determinados como tuberculoide y lepromatoso, una forma indeterminada y borderline. Por otro lado se considera que la reacciones lepróticas (tipo 1, tipo 2 y fenómeno de lucio son complicaciones de la hiperreactividad inmunológica que aparece cuando se afecta el equilibrio inmunológico en el huésped. En 1982 la Organización Mundial de la Salud estableció la terapia multidrogas como herramienta eficaz para el control de esta entidad. Actualmente el régimen farmacológico se establece teniendo en cuenta la clasificación que distingue al enfermo en paucibacilar y multibacilar. Presentamos un paciente masculino de 64 años, con antecedente de lepra lepromatosa multibacilar desde hace 3 años, con tratamiento irregular, suspendido 6 meses antes de clínica de ingreso consistente sepsis de origen urinario, con posterior septicemia asociada al catéter, a quien se le realiza tratamiento antibiótico de amplio espectro, con evolución satisfactoria del estado hemodinámico y manejo de la lepra ambulatorio.

    2015-05-01

    Full Text Available El asma es una enfermedad frecuente de fisiopatología compleja. El asma severa constituye aproximadamente el 5% de la población de asmáticos, sin embargo representa un desafío clínico y una carga sanitaria importante. Estudios recientes demuestran la existencia de fenotipos en todo el espectro de gravedad. La eosinofilia en esputo y sangre ha demostrado utilidad como marcador de inflamación Th-2 y de respuesta clínica a esteroides, sin embargo aún no existe mucho conocimiento sobre el asma no-eosinofílica. Los tratamientos actuales en asma se enfocan a estrategias de terapia escalonada según severidad, pero en pacientes con asma severa se requiere también del manejo multidisciplinario de las comorbilidades y la determinación del fenotipo, para aplicar terapias más especificas. El desarrollo acelerado de nuevos tratamientos en asma severa como consecuencia del mejor conocimiento de los distintos fenotipos ha ampliado el arsenal terapéutico para un enfrentamiento personalizado y específico en los pacientes con asma severa.

    Full Text Available Resumen La obesidad es una enfermedad compleja y multifactorial que puede iniciarse en la infancia, y se caracteriza por un exceso de grasa corporal que coloca al individuo en una situación de riesgo para la salud. La práctica regular de actividad física/ejercicio físico se ha convertido en uno de los objetivos principales de los planes de salud pública, debido a su relación con la prevención y tratamiento de la obesidad. En población infantil europea, el hábito de ejercicio físico es bajo y disminuye al aumentar la edad. Los objetivos del estudio fueron: (i mostrar la metodología de las sesiones desarrolladas en un programa de ejercicio físico dirigido en niños con obesidad severa, y (ii describir las ventajas e inconvenientes de las sesiones desarrolladas en el día a día con esta población. Las conclusiones que se pueden extraer de este trabajo son: (a en esta población resulta importante plantear actividades cooperativas, en el que todos tengan posibilidades de participar independientemente de sus características y habilidades individuales y (b en ocasiones y debido a la heterogeneidad observada durante las sesiones, es importante plantear y establecer varias actividades paralelas, aunando más si cabe las motivaciones y gustos de los participantes.

    Full Text Available Resumen La obesidad es una enfermedad compleja y multifactorial que puede iniciarse en la infancia, y se caracteriza por un exceso de grasa corporal que coloca al individuo en una situación de riesgo para la salud. La práctica regular de actividad física/ejercicio físico se ha convertido en uno de los objetivos principales de los planes de salud pública, debido a su relación con la prevención y tratamiento de la obesidad. En población infantil europea, el hábito de ejercicio físico es bajo y disminuye al aumentar la edad. Los objetivos del estudio fueron: (i mostrar la metodología de las sesiones desarrolladas en un programa de ejercicio físico dirigido en niños con obesidad severa, y (ii describir las ventajas e inconvenientes de las sesiones desarrolladas en el día a día con esta población. Las conclusiones que se pueden extraer de este trabajo son: (a en esta población resulta importante plantear actividades cooperativas, en el que todos tengan posibilidades de participar independientemente de sus características y habilidades individuales y (b en ocasiones y debido a la heterogeneidad observada durante las sesiones, es importante plantear y establecer varias actividades paralelas, aunando más si cabe las motivaciones y gustos de los participantes.

    Full Text Available This study presents the results obtained from the evaluation, by specialist judges, of the Supports Intensity Scale (SIS, Spanish version, to determine its suitability for the Mexican population with severe mental illness (SMI. The instrument, originally designed for people with intellectual disabilities, is consistent with the multidimensional concept of quality of life and the social model of disability. The semantic equivalence of the items adjusted by specialist judges, the reliability of the subscales, using Cronbach’s alpha, and the concurrent validity between the SIS and the Global Functioning Assessment (GAF were analyzed. The mean similarity to the original was 9.91 from a total of 10 (sd=0.14. The reliability coefficients were above 0.95 and the correlations between the SIS and the GAF were medium to high and significant. In conclusion, in the Mexican context, the SIS scale can be used to understand the needs and expectations of people with mental illness.Mostramos resultados obtenidos en la evaluación de jueces expertos en la Escala de Intensidad de Apoyos (SIS, versión española, para determinar su adecuación a la población mexicana con Enfermedad Mental Severa (EMS.

A diferencia de la EPOC por cigarrillo (EPOC-C, para un mismo nivel de obstrucción, en la EPOC por leña (EPOC-L, la DLCO está menos disminuida, sugiriendo menos enfisema. Por tanto, el objetivo de este estudio fue comparar los hallazgos en la TCAR en mujeres con EPOC-L y con EPOC- C. MÉTODOS: Veintidós mujeres con EPOC severa (VEF1/CVF OBJECTIVE: Wood smoke exposure is a risk factor for COPD. For a given degree of airway obstruction, the reduction in DLCO is smaller in individuals with wood smoke-related COPD than in those with smoking-related COPD, suggesting that there is less emphysema in the former. The objective of this study was to compare HRCT findings between women with wood smoke-related COPD and women with smoking-related COPD. METHODS: Twenty-two women with severe COPD (FEV1/FVC ratio < 70% and FEV1 < 50% were divided into two groups: those with wood smoke-related COPD (n = 12 and those with smoking-related COPD (n = 10. The two groups were compared regarding emphysema scores and airway involvement (as determined by HRCT; and functional abnormalities-spirometry results, DLCO, alveolar volume (VA, the DLCO/VA ratio, lung volumes, and specific airway resistance (sRaw. Results: There were no significant differences between the two groups in terms of FEV1, sRaw, or lung hyperinflation. Decreases in DLCO and in the DLCO/VA ratio were greater in the smoking-related COPD group subjects, who also had higher emphysema scores, in comparison with the wood smoke-related COPD group subjects. In the wood smoke-related COPD group, HRCT scans howed no significant emphysema, the main findings being peribronchial thickening, bronchial dilation, and subsegmental atelectasis. CONCLUSIONS: Female patients with severe wood smoke-related COPD do not appear to develop emphysema, although they do show severe airway involvement. The reduction in DLCO and VA, with a normal DLCO

    Full Text Available El estafilococo coagulasa negativa es actualmente un importante patógeno nosocomial y agente causal de infección en el neonato. Cepas multirresistentes comúnmente aisladas de recién nacidos sometidos a cuidados intensivos dificultan la terapéutica, por lo que se hace necesario el empleo de combinaciones antibióticas que garanticen un efecto antibacteriano más eficiente. Se presentan los resultados obtenidos en un paciente con bronconeumonía adquirida por Staphylococcus haemolyticus multirresistente y que fue sometido a tratamiento combinado de azlocillin y amikacina. Se estudió el patrón de resistencia de la cepa para 30 antibióticos por métodos de difusión y dilución, así como la efectividad in vitro de la combinación antibiótica aplicada por el método del «tablero de ajedrez». Se observó en los resultados in vitro una marcada potencialización de la actividad aminoglucosídica por la presencia del antibiótico beta-lactámico, resultado que se correspondió con una excelente respuesta in vivo.Negative-coagulase Staphyloccocus, is at present time an important nosocomial pathogen and a causal agent of neonatal infection. Multirresistant strains commonly isolated from newborn under intensive care, make difficult treatment, so it is necessary use of antibiotic combination to assure a more efficient antibacterial effect. We present results obtained in a patient presenting with acquired bronchopneumonia from multirresistant Staphylococcus haemolyticus who received a combination of Azlocillin and Amikacin. Resistance pattern to this strain was studied by diffusion and dilution methods, as well as in vitro effectiveness of antibiotic combination, applied by "Chequerboard" method. In in vitro results, we found a significant potentiation of aminoglucoside activity by presence of Beta-lactamic antibiotic, result corresponding to an in vivo excellent response.

    Educators are under tremendous pressure to ensure that their students perform well on tests.  Unfortunately, this pressure has caused some educators to cheat.  The purpose of this study was to investigate the types of, and degrees to which, a sample of teachers in Arizona were aware of, or had themselves engaged in test-related cheating practices as a function of the high-stakes testing policies of No Child Left Behind. A near census sample of teachers was surveyed, with valid responses obtained from about 5 percent, totaling just over 3,000 teachers. In addition, one small convenience sample of teachers was interviewed, and another participated in a focus group. Data revealed that cheating occurs and that educators can be quite clever when doing so. But how one defines cheating makes it difficult to quantify the frequency with which educators engage in such practices. Our analysis thus required us to think about a taxonomy of cheating based on the definitions of 1st, 2nd, and 3rd degree offenses in the field of law. These categories were analyzed to help educators better define, and be more aware of others' and their own cheating practices, in an attempt to inform local testing policies and procedures.

    Sepsis is a common cause of hospital admission worldwide and contributes significantly to morbidity and mortality. The definition of sepsis has evolved from the 1991 American College of Chest Physicians/Society of Critical Care Medicine definition based on the criteria of systemic inflammatory response syndrome, to the 2016 Sepsis-3 definition that incorporates the Sequential Organ Failure Assessment score. The landmark trial on protocolised early goal-directed therapy was published in 2001, but three subsequent multicentre randomised controlled trials (ProCESS, ARISE, and ProMISe) in 2014-2015 did not confirm a survival benefit with protocolised care. Over the years, there has been considerable improvement in sepsis outcome and management that hinges on early detection; timely source control; prompt, appropriate, and correctly dosed antibiotics; aggressive fluid resuscitation; and shock reversal. These are all directed by repeated bedside assessment. This article summarises recent developments and landmark trials that should guide current sepsis management.

Rapid recognition of sepsis as the cause of deterioration is desirable, so effective treatment can be initiated rapidly. Traditionally, diagnosis was based on presence of two...... or more positive SIRS criteria due to infection. However, recently published sepsis-3 criteria put more emphasis on organ dysfunction caused by infection in the definition of sepsis.

  9. Biomarkers of sepsis

    Science.gov (United States)

    2013-01-01

    Sepsis is an unusual systemic reaction to what is sometimes an otherwise ordinary infection, and it probably represents a pattern of response by the immune system to injury. A hyper-inflammatory response is followed by an immunosuppressive phase during which multiple organ dysfunction is present and the patient is susceptible to nosocomial infection. Biomarkers to diagnose sepsis may allow early intervention which, although primarily supportive, can reduce the risk of death. Although lactate is currently the most commonly used biomarker to identify sepsis, other biomarkers may help to enhance lactate’s effectiveness; these include markers of the hyper-inflammatory phase of sepsis, such as pro-inflammatory cytokines and chemokines; proteins such as C-reactive protein and procalcitonin which are synthesized in response to infection and inflammation; and markers of neutrophil and monocyte activation. Recently, markers of the immunosuppressive phase of sepsis, such as anti-inflammatory cytokines, and alterations of the cell surface markers of monocytes and lymphocytes have been examined. Combinations of pro- and anti-inflammatory biomarkers in a multi-marker panel may help identify patients who are developing severe sepsis before organ dysfunction has advanced too far. Combined with innovative approaches to treatment that target the immunosuppressive phase, these biomarkers may help to reduce the mortality rate associated with severe sepsis which, despite advances in supportive measures, remains high.

    For more than two decades, sepsis was defined as a microbial infection that produces fever (or hypothermia), tachycardia, tachypnoea and blood leukocyte changes. Sepsis is now increasingly being considered a dysregulated systemic inflammatory and immune response to microbial invasion that produces organ injury for which mortality rates are declining to 15–25%. Septic shock remains defined as sepsis with hyperlactataemia and concurrent hypotension requiring vasopressor therapy, with in-hospital mortality rates approaching 30–50%. With earlier recognition and more compliance to best practices, sepsis has become less of an immediate life-threatening disorder and more of a long-term chronic critical illness, often associated with prolonged inflammation, immune suppression, organ injury and lean tissue wasting. Furthermore, patients who survive sepsis have continuing risk of mortality after discharge, as well as long-term cognitive and functional deficits. Earlier recognition and improved implementation of best practices have reduced in-hospital mortality, but results from the use of immunomodulatory agents to date have been disappointing. Similarly, no biomarker can definitely diagnose sepsis or predict its clinical outcome. Because of its complexity, improvements in sepsis outcomes are likely to continue to be slow and incremental.

    Full Text Available There is a higher sepsis rate in the intensive care unit (ICU patients, which is one of the most important causes for patient death, but the sepsis lacks specific clinical manifestations. Exploring sensitive and specific molecular markers for infection that accurately reflect infection severity and prognosis is very clinically important. In this article, based on our previous study, we introduce some new biomarkers with high sensitivity and specificity for the diagnosis and predicting the prognosis and severity of sepsis. Increase of serum soluble(s triggering receptor expressed on myeloid cells-1 (sTREM-1 suggests a poor prognosis of septic patients, and changes of locus rs2234237 of sTREM-1 may be the one of important mechanisms. Additionally, urine sTREM-1 can provide an early warning of possible secondary acute kidney injury (AKI in sepsis patients. Serum sCD163 level was found to be a more important factor than procalcitonin (PCT and C-reactive protein (CRP in prognosis of sepsis, especially severe sepsis. Moreover, urine sCD163 also shows excellent performance in the diagnosis of sepsis and sepsis-associated AKI. Circulating microRNAs, such as miR-150, miR-297, miR-574-5p, miR -146a , miR-223, miR -15a and miR-16, also play important roles in the evaluation of status of septic patients. In the foreseeable future, newly-emerging technologies, including proteomics, metabonomics and trans-omics, may exert profound effects on the discovery of valuable biomarkers for sepsis.

    Sepsis is the life-threatening condition with organ dysfunction caused by dysregulated host response to the infection. Septic shock is part of sepsis where circulatory abnormalities and cellular metabolism occur. Sepsis and septic shock are still a problem in the world, where one in four people with sepsis will die. As well as any trauma case, acute myocardial infarction, or stroke, early identification and appropriate treatment of sepsis immediately after sepsis will improve the prognosis of the patient. Comprehensive management of septic patients is required, ranging from infection controls that include antibiotic administration and infection source control as well as hemodynamic stabilization that included fluid resuscitation and vasoactive drug delivery.

    Three therapeutic principles most substantially improve organ dysfunction and survival in sepsis: early, appropriate antimicrobial therapy; restoration of adequate cellular perfusion; timely source control. The new definitions of sepsis and septic shock reflect the inadequate sensitivity, specify, and lack of prognostication of systemic inflammatory response syndrome criteria. Sequential (sepsis-related) organ failure assessment more effectively prognosticates in sepsis and critical illness. Inadequate cellular perfusion accelerates injury and reestablishing perfusion limits injury. Multiple organ systems are affected by sepsis and septic shock and an evidence-based multipronged approach to systems-based therapy in critical illness results in improve outcomes.

    Full Text Available Micronutrients are nutrients which are needed by the body to perform the function of body. The amounts is less than 100% μg per day and consist of vitamins and minerals. It cannot be synthesized in the body. Research in the US mentioned that the rate prevalence of sepsis is tended to be increased 8.7 % annually. In sepsis, nutrition is one of the important component which could drive the success treatment. Micronutrient, especially a vitamin which is soluble in fats, it would be toxic if the number exceed the capability of body to receive it. Although there are guidance and mutual agreement about sepsis using, it still need to concern on micronutrient which potentially giving bad effect. In sepsis case, micronutrients also determine the success of treatment due to redistribution of vitamin and trace element from circulation to the tissue which involved in the proteins formation and immune system. The conclusions of the latest 7 experiments and 4 random controlled studies of multi-centre support the micronutrients supplementation because it can decrease mortality rate. However, it still need to be aware to the toxicity of fat soluble micronutrient if the doses are excessive.

    Full Text Available Sepsis associated encephalopathy (SAE is a common but poorly understood neurological complication of sepsis. It is characterized by diffuse brain dysfunction secondary to infection elsewhere in the body without overt CNS infection. The pathophysiology of SAE is complex and multifactorial including a number of intertwined mechanisms such as vascular damage, endothelial activation, breakdown of the blood brain barrier, altered brain signaling, brain inflammation, and apoptosis. Clinical presentation of SAE may range from mild symptoms such as malaise and concentration deficits to deep coma. The evaluation of cognitive dysfunction is made difficult by the absence of any specific investigations or biomarkers and the common use of sedation in critically ill patients. SAE thus remains diagnosis of exclusion which can only be made after ruling out other causes of altered mentation in a febrile, critically ill patient by appropriate investigations. In spite of high mortality rate, management of SAE is limited to treatment of the underlying infection and symptomatic treatment for delirium and seizures. It is important to be aware of this condition because SAE may present in early stages of sepsis, even before the diagnostic criteria for sepsis can be met. This review discusses the diagnostic approach to patients with SAE along with its epidemiology, pathophysiology, clinical presentation, and differential diagnosis.

  20. Sepsis attenuates the anabolic response to skeletal muscle contraction.

    Electrically stimulated muscle contraction is a potential clinical therapy to treat sepsis-induced myopathy; however, whether sepsis alters contraction-induced anabolic signaling is unknown. Polymicrobial peritonitis was produced by cecal ligation and puncture (CLP) in male C57BL/6 mice and time-matched, pair-fed controls (CON). At ∼24 h post-CLP, the right hindlimb was electrically stimulated via the sciatic nerve to evoke maximal muscle contractions, and the gastrocnemius was collected 2 h later. Protein synthesis was increased by muscle contraction in CON mice. Sepsis suppressed the rate of synthesis in both the nonstimulated (31%) and stimulated (57%) muscle versus CON. Contraction of muscle in CON mice increased the phosphorylation of mTORC1 (mammalian target of rapamycin [mTOR] complex 1) substrates S6K1 (70-kd ribosomal protein S6 kinase 1) Thr (8-fold), S6K1 ThrSer (7-fold) and 4E-BP1 Ser (11-fold). Sepsis blunted the contraction-induced phosphorylation of S6K1 Thr (67%), S6K1 ThrSer (46%), and 4E-BP1 Ser (85%). Conversely, sepsis did not appear to modulate protein elongation as eEF2 Thr phosphorylation was decreased similarly by muscle contraction in both groups. Mitogen-activated protein kinase signaling was discordant following contraction in septic muscle; phosphorylation of extracellular signal-regulated kinase ThrTyr and p38 ThrTyr was increased similarly in both CON and CLP mice, while sepsis prevented the contraction-induced phosphorylation of JNK ThrTyr and c-JUN Ser. The expression of interleukin 6 and tumor necrosis factor α (TNF-α) mRNA in muscle was increased by sepsis, and contraction increased TNF-α to a greater extent in muscle from septic than CON mice. Injection of the mTOR inhibitor Torin2 in separate mice confirmed that contraction-induced increases in S6K1 and 4E-BP1 were mTOR mediated. These findings demonstrate that resistance to contraction-induced anabolic signaling occurs during sepsis and is predominantly mTORC1-dependent.

    las etiologías más frecuentes se localizan a nivel colónico. El objetivo es analizar el manejo diagnóstico-terapéutico de las HDB severas cuya etiología se localizaba en el intestino delgado. Pacientes y métodos: entre 1975 y marzo del 2002 ingresaron en nuestro servicio 12 HDB severas originadas en el intestino delgado. Todos consultaron por rectorragia franca, precisando al menos transfusión de 3 unidades de concentrados de hematíes. La edad media fue de 54 ± 21 años, el 58% eran mujeres, y el 83% había presentado cuadros previos de HDB. Resultados: en once casos (92% se realizó una endoscopia digestiva alta y baja urgente no objetivando el origen del sangrado. La arteriografía se indicó en 7 pacientes (58%, localizando en 5 de ellos el sangrado. En dos casos se hizo una gammagrafía mostrando en uno un divertículo de Meckel y en el otro fue normal. Todos se intervinieron, 8 (67% de urgencias, encontrándose un tumor en 9 casos y un divertículo de Meckel en 3, realizándose resección de todas las lesiones. La histología informó de leiomioma en 7 casos, de divertículo de Meckel en 3, de leiomioblastoma en 1 y de angioma en el caso restante. Tras un seguimiento medio de 132 ± 75 meses, fue éxitus el leiomioblastoma, y recidivó el angioma, el cual fue embolizado radiológicamente con éxito. Conclusiones: la HDB severa de origen en intestino delgado debe considerarse como posibilidad etiológica cuando la endoscopia digestiva no objetiva el origen del sangrado, siendo la arteriografía una técnica diagnóstica útil para localizar el sangrado. La cirugía supone el tratamiento definitivo del proceso, confirma la etiología, y descarta la presencia de malignidad.

    2012-03-01

    Full Text Available Introduction. Endotoxin, a component of the cell wall of Gram-negative bacteria is a major contributor to the pathogenesis of septic shock and multiple organ failure (MOF. Its entry into the bloodstream stimulates monocytes/macrophages which once activated produce and release cytokines, nitric oxide and other mediators that induce systemic inflammation, endothelial damage, organ dysfunction, hypotension (shock and MOF.The aim of this study is to evaluate the usefulness of a quantitative test for the dosage of endotoxin to determine the risk of severe Gram-negative sepsis. Materials and methods. In the period January 2009 - June 2011 we performed 897 tests for 765 patients, mostly coming from the emergency room and intensive care, of which 328 (43% women (mean age 53 and 437 (57% male (mean age 49. Fifty-nine patients, no statistically significant difference in sex, were monitored by an average of two determinations of EA.All patients had procalcitonin values significantly altered.The kit used was EAA (Endotoxin Activity Assay Estor Company, Milan, which has three ranges of endotoxin activity (EA: low risk of sepsis if <0.40 units, medium if between 0.40 and 0.59; high if 0.60. Results. 78 out of 765 patients (10% had a low risk, 447 (58% a medium risk and 240 (32% a high risk.The dosage of EA, combined with that of procalcitonin, has allowed a more targeted antibiotic therapy. Six patients in serious clinical conditions were treated by direct hemoperfusion with Toraymyxin, a device comprising a housing containing a fiber polypropylene and polystyrene with surface-bound polymyxin B, an antibiotic that removes bacterial endotoxins from the blood. Conclusions.The test is useful in risk stratification as well as Gram negative sepsis, to set and monitor targeted therapies, also based on the neutralization of endotoxin.

    Full Text Available Objective. To comparatively analyze the efficiency of methods for extracorporeal detoxification (ED of the body in abdominal sepsis (AS and to choose the optimum detoxifying methods in relation to the level of endotoxicosis.Material and methods. 56 patients (41 males and 15 females; mean age 39.4±12.2 years with surgical abdominal infection of various genesis, complicated by the development of sepsis whose treatment included ED methods, were examined. The level of intoxication and the efficiency of detoxification were evaluated by general clinical and biochemical blood parameters, the leukocytic intoxication index, the levels of low and medium molecular-weight substances in the body’s media. Hemosorption, plasmapheresis, hemodialysis, hemodiafiltration, and hemofiltration were used for detoxification.Results. Surgical abdominal infection is accompanied by endotoxemia that has no clear nosological specificity, but it depends on the pattern of a clinical course of the disease and is most pronounced in the septic syndrome. In AS, 80.4% of the patients are observed to have an irreversible decompensation phase and a terminal degree of endotoxicosis, which require detoxification. The use of different ED methods according to the level of intoxication may reduce the level of endotoxicosis and yield a persistent beneficial effect in 85.2% of cases of its application. Conclusion. Filtration and dialysis techniques (hemodialysis, hemofiltration, and hemodiafiltration are the methods of choice in AS. Hemosorption and plasmapheresis may be recommended for use at the early stages of endotoxicosis development and in preserved renal excretory function.

    Sepsis morbidity and mortality exacts a toll on patients and contributes significantly to healthcare costs. Preclinical models of sepsis have been used to study disease pathogenesis and test new therapies, but divergent outcomes have been observed with the same treatment even when using the same sepsis model. Other disorders such as diabetes, cancer, malaria, obesity and cardiovascular diseases have used standardized, preclinical models that allow laboratories to compare results. Standardized models accelerate the pace of research and such models have been used to test new therapies or changes in treatment guidelines. The National Institutes of Health (NIH) mandated that investigators increase data reproducibility and the rigor of scientific experiments and has also issued research funding announcements about the development and refinement of standardized models. Our premise is that refinement and standardization of preclinical sepsis models may accelerate the development and testing of potential therapeutics for human sepsis, as has been the case with preclinical models for other disorders. As a first step towards creating standardized models, we suggest 1) standardizing the technical standards of the widely used cecal ligation and puncture model and 2) creating a list of appropriate organ injury and immune dysfunction parameters. Standardized sepsis models could enhance reproducibility and allow comparison of results between laboratories and may accelerate our understanding of the pathogenesis of sepsis.

    2005-06-01

    Although it is considered that metabolic and nutritional support must be part of the management of septic patients, it has not been conclusively shown that nutritional support will improve survival or complications from sepsis. Specific data on this issue are scarce since there are few studies that have investigated specialized nutritional support in septic patients. Thus, most of the recommendations are based on outcomes obtained in severely ill patients with different pathologies. It is assumed that nutritional support should be carried out through the enteral route whenever possible, as in other critically ill patients. The energetic waste in these patients is highly variable, although in general terms the hypermetabolic situation may be classified as moderate. An adjustment factor of 1.25-1.30 is recommended for the Harris-Benedict's equation to calculate the caloric intake. Septic patients should receive a hyperproteic intake. The amount of glucose administered should not exceed 70% of non-protein calories, and lipids intake should not exceed 40%. With regards to micronutrients, it is recommended to increase the supply of those with antioxidant properties (vitamin E, carotenes, vitamin C, selenium). There are data to consider that the use of diets enriched with pharmaco-nutrients (both with parenteral and enteral routes) may be beneficial in septic patients, although there is some controversy when interpreting the outcomes.

    Both experimental and clinical evidence suggest a suppression of T-cell function in burn and sepsis. The objective of the present study was to evaluate splenocyte and purified T-cell proliferative response and IL-2 production in septic neonatal rats. We also examined if alterations in T-cell proliferation and IL-2 production in neonatal sepsis is due to elevation in PGE2. PGE2 is known to play a significant role in T-cell suppression during sepsis in adults. Sepsis was induced in 15-day-old neonatal Sprague-Dawley rats by implanting 0.1 cm3 of fecal pellet impregnated with Escherichia coli (50 CFU) and Bacteroides fragilis (10(3) CFU). Animals receiving fecal pellets without the bacteria were designated as sterile. A group of septic and sterile rats were treated with PGE2 synthesis inhibitors, NS398 and resveratrol. These treatments of animals allowed us to evaluate the role of PGE2 in T-cell suppression during neonatal sepsis. Splenocytes as well as purified T cells were prepared and then proliferative response and IL-2 productive capacities were measured. A significant suppression of splenocyte proliferation and IL-2 production was noticed in both sterile and septic animals compared to the T cells from unoperated control rats. In contrast, the proliferation and IL-2 production by nylon wool purified T cells in sterile rats was not significantly different from control rats, whereas, a significant suppression in Con A-mediated T-cell proliferation and IL-2 production noticed in septic rat T cells compared to the sterile and control rat T cells. Such decrease in T-cell proliferation and IL-2 production was accompanied with 20-25% deaths in neonates implanted with septic pellets. No mortality was noted in sterile-implanted neonates. Treatment of animals with COX-1 inhibitor had no effect on T-cell proliferation response in both septic and sterile groups, whereas COX-2 inhibitor abrogated the decrease in T-cell proliferative response in the septic group.

    2017-07-01

    MicroRNAs have been found to be of high significance in the regulation of various genes and processes in the body. Sepsis is a serious clinical problem which arises due to the excessive host inflammatory response to infection. The non-specific clinical features and delayed diagnosis of sepsis has been a matter of concern for long time. MicroRNAs could enable better diagnosis of sepsis and help in the identification of the various stages of sepsis. Improved diagnosis may enable quicker and more effective treatment measures. The initial acute and transient phase of sepsis involves excessive secretion of pro-inflammatory cytokines which causes severe damage. MicroRNAs negatively regulate the toll-like receptor signaling pathway and regulate the production of inflammatory cytokines during sepsis. Likewise, microRNAs have shown to regulate the vascular barrier and endothelial function in sepsis. They are also involved in the regulation of the apoptosis, immunosuppression, and organ dysfunction in later stages of sepsis. Their importance at various levels of the pathophysiology of sepsis has been discussed along with the challenges and future perspectives. MicroRNAs could be key players in the diagnosis and staging of sepsis. Their regulation at various stages of sepsis suggests that they may have an important role in altering the outcome associated with sepsis.

    Full Text Available BACKGROUND Of the 130 million babies born worldwide each year, 26 million are born in India alone. Four million babies die with in first 30 days of birth and another four million are stillborn. Newborn mortality represents 40% of all deaths of children less than five years of age. Of the four million deaths each year, nearly 98% occur in developing countries. Globally major causes of neonatal deaths are due to preterm births (28%, sepsis or pneumonia (26% and birth asphyxia (23%. Neonatal sepsis is one of the commonest causes of neonatal deaths in the developing world accounting to 30-50% of all neonatal deaths per year. The present study is intended to help the practising paediatrician to accurately diagnose the sepsis early using the specific laboratory tests and avert the progression of the disease. METHODS It is an observational cross-sectional study in NICU, Mahatma Gandhi Memorial Hospital. The study was conducted in the period November 2013 to October 2014. After admission, detailed history and thorough clinical examination was done. Required data was entered in a pre-set proforma and statistical analysis was done. Blood culture was sent. Bacterial culture and sensitivity was checked. RESULTS In proven sepsis, 50.25% were Gram-positive, 43.65% were Gram-negative and 6.09% were fungal sepsis Candida. Klebsiella (32.48% was the most common organism followed by Coagulase positive Staphylococcus (25.38% and CONS (20.81%. In this study, Gram-negative sepsis was more common in preterm and Gram-positive sepsis was more common in term neonates. Early onset sepsis was the common presentation of proven sepsis, Klebsiella was common organism causing EOS. Whereas CONS was commonest causing late onset sepsis. Among Gram-negative organisms, 58.1% and 27.9% were resistant to cefotaxime and ampicillin+sulbactam respectively.

    Full Text Available Sepsis is a syndrome related to severe infections. It is defined as the systemic host response to microorganisms in previously sterile tissues and is characterized by end-organ dysfunction away from the primary site of infection. The normal host response to infection is complex and aims to identify and control pathogen invasion, as well as to start immediate tissue repair. Both the cellular and humoral immune systems are activated, giving rise to both anti-inflammatory and proinflammatory responses. The chain of events that leads to sepsis is derived from the exacerbation of these mechanisms, promoting massive liberation of mediators and the progression of multiple organ dysfunction. Despite increasing knowledge about the pathophysiological pathways and processes involved in sepsis, morbidity and mortality remain unacceptably high. A large number of immunomodulatory agents have been studied in experimental and clinical settings in an attempt to find an efficacious anti-inflammatory drug that reduces mortality. Even though preclinical results had been promising, the vast majority of these trials actually showed little success in reducing the overwhelmingly high mortality rate of septic shock patients as compared with that of other critically ill intensive care unit patients. Clinical management usually begins with prompt recognition, determination of the probable infection site, early administration of antibiotics, and resuscitation protocols based on "early-goal" directed therapy. In this review, we address the research efforts that have been targeting risk factor identification, including genetics, pathophysiological mechanisms and strategies to recognize and treat these patients as early as possible.

    Full Text Available Sepsis is a lethal syndrome with a high incidence and a weighty economy burden. The pathophysiology of sepsis includes inflammation, immune dysfunction, and dysfunction of coagulation, while sepsis-induced cardiomyopathy (SIC, defined as a global but reversible dysfunction of both sides of the heart induced by sepsis, plays a significant role in all of the aspects above in the pathogenesis of sepsis. The complex pathogenesis of SIC involves a combination of dysregulation of inflammatory mediators, mitochondrial dysfunction, oxidative stress, disorder of calcium regulation, autonomic nervous system dysregulation, and endothelial dysfunction. The treatments for SIC include the signal pathway intervention, Chinese traditional medicine, and other specific therapy. Here, we reviewed the latest literatures on the mechanisms and treatments of SIC and hope to provide further insights to researchers and create a new road for the therapy of sepsis.

  2. Experimental sepsis impairs humoral memory in mice.

    Directory of Open Access Journals (Sweden)

    Christian Pötschke

    Full Text Available Patients with sepsis are often immune suppressed, and experimental mouse models of sepsis also display this feature. However, acute sepsis in mice is also characterized by a generalized B cell activation and plasma cell differentiation, resulting in a marked increase in serum antibody concentration. Its effects on humoral memory are not clearly defined. We measured the effects of experimental sepsis on long-term immunological memory for a defined antigen: we induced colon ascendens stent peritonitis (CASP 8 weeks after 2 rounds of immunization with ovalbumin. Four weeks later, the antigen-specific bone marrow plasma cell count had doubled in immunized non-septic animals, but remained unchanged in immunized septic animals. Sepsis also caused a decrease in antigen-specific serum antibody concentration. We conclude that sepsis weakens humoral memory by impeding the antigen-specific plasma cell pool's development, which is not complete 8 weeks after secondary immunization.

Sepsis-associated liver dysfunction is mainly resulted from systemic or microcirculatory disturbances, spillovers of bacteria and endotoxin (lipopolysaccharide, LPS, and subsequent activation of inflammatory cytokines as well as mediators. Three main cell types of the liver which contribute to the hepatic response in sepsis are Kupffer cells (KCs, hepatocytes and liver sinusoidal endothelial cells (LSECs. In addition, activated neutrophils, which are also recruited to the liver and produce potentially destructive enzymes and oxygen-free radicals, may further enhance acute liver injury. The clinical manifestations of sepsis-associated liver dysfunction can roughly be divided into two categories: Hypoxic hepatitis and jaundice. The latter is much more frequent in the context of sepsis. Hepatic failure is traditionally considered as a late manifestation of sepsis-induced multiple organ dysfunction syndrome. To date, no specific therapeutics for sepsis-associated liver dysfunction are available. Treatment measure is mainly focused on eradication of the underlying infection and management for severe sepsis. A better understanding of the pathophysiology of liver response in sepsis may lead to further increase in survival rates.

    Full Text Available Bajo la perspectiva del interaccionismo simbólico se analiza como influyen los factores del entorno en la relación de cuidado establecida por cuidadores primarios de personas con enfermedad mental severa en México. El cuidado se encuentra circunscrito al ámbito familiar dado el escaso desarrollo de una red social que proporcione los apoyos necesarios para favorecer la integración social. A esta situación han contribuido la naturalización cultural de los roles que desempeñan las mujeres como cuidadoras natas y las personas con enfermedad mental como dependientes, favoreciendo de esta forma la aceptación de alternativas como la institucionalización. La visualización del cuidado como responsabilidad individual favorece la situación de vulnerabilidad social, emocional y económica en la que se encuentran los cuidadores primarios y personas con enfermedad mental de este estudio.Under the perspective of symbolic interactionism analyzes how environmental factors influence the relationship of care provided by primary caregivers of people with severe mental illness in Mexico. The care is restricted to the family given the limited development of a social network to provide the necessary support to promote social integration. This situation has contributed the cultural naturalization of the roles that women plays as natural born caregivers and people with mental illness as a dependent person, consequently, encouraging the acceptance of alternatives such as institutionalization. The display of care as individual responsibility benefits the vulnerable social, emotional and economic situation, in which are the primary caregivers and people with mental illness in this study.

    Full Text Available Sepsis can sometimes be difficult to substantiate, and its distinction from non-infectious conditions in critically ill patients is often a challenge. Serum procalcitonin (PCT assay is one of the biomarkers of sepsis. The present study was aimed to assess the usefulness of PCT assay in critically ill patients with suspected sepsis. The study included 40 patients from the intensive care unit with suspected sepsis. Sepsis was confirmed clinically and/or by positive blood culture. Serum PCT was assayed semi-quantitatively by rapid immunochromatographic technique (within 2 hours of sample receipt. Among 40 critically ill patients, 21 had clinically confirmed sepsis. There were 12 patients with serum PCT ≥10 ng/ml (8, blood culture positive; 1, rickettsia; 2, post-antibiotic blood culture sterile; and 1, non-sepsis; 7 patients with PCT 2-10 ng/ml (4, blood culture positive; 1, falciparum malaria; 2, post-antibiotic blood culture sterile; 3 patients with PCT of 0.5 to 2 ng/ml (sepsis in 1 patient; and 18 patients with PCT < 0.5 ng/ml (sepsis in 2 patients. Patients with PCT ≥ 2 ng/ml had statistically significant correlation with the presence of sepsis (P<0.0001. The PCT assay revealed moderate sensitivity (86% and high specificity (95% at a cut-off ≥ 2 ng/ml. The PCT assay was found to be a useful biomarker of sepsis in this study. The assay could be performed and reported rapidly and provided valuable information before availability of culture results. This might assist in avoiding unwarranted antibiotic usage.

    Full Text Available The aim of this study is to evaluate additional hospitalisation costs and intangible costs (mortality in patients with sepsis (intended as severe sepsis or sepsis shock in Italy. The evaluation is based on clinical data from the Italian Sepsis Study, a prospective, multicentre study conducted in 99 Intensive Care Units (ICUslocated across Italy. Each ICU enrolled the first two (or three patients admitted each month, during the year April 1993 to March 1994. In particular, data collected included the Average Length Of Stay (ALOS in ICU and later in the regular ward, and the mortality within four weeks and in hospital. Out of the 2,946 patients enrolled, 2,641 never developed sepsis and were considered as the control group (comparability was confirmed based on gender, age, and comorbidity. The additional (respective to the control group ALOSs of the patients with sepsis were valued in monetary terms using per diem full costs, inflated to 2000: 1,033.43 Euro for l day in ICU (published data and 299.54 Euro for l day in the regular ward (estimated data based on published materials. Statistical significance was tested with Student t test. The hospitalisation cost of a patient with sepsis (21,571.88 Euro is significantly higher (+86% than that patient without sepsis (11,590.84 Euro, due to a longer (+ 163% stay in the expensive ICU, not balanced by shorter stay in the regular ward. Also intangible costs are significantly higher: the risk for an ICU patient with sepsis to die in hospital is 3 times higher than that of an ICU patient without sepsis. In particular, those patients developing sepsis after admission are more costly and with a higher mortality risk.

    Sepsis is characterized by microvascular dysfunction and thrombophilia. Several methionine metabolites may be relevant to this sepsis pathophysiology. S-adenosylmethionine (SAM) serves as the methyl donor for trans-methylation reactions. S-adenosylhomocysteine (SAH) is the by-product of these reactions and serves as the precursor to homocysteine. Relationships between plasma total homocysteine concentrations (tHcy) and vascular disease and thrombosis are firmly established. We hypothesized that SAM, SAH, and tHcy levels are elevated in patients with sepsis and associated with mortality. This was a combined case-control and prospective cohort study consisting of 109 patients with sepsis and 50 control participants without acute illness. The study was conducted in the medical and surgical intensive care units of the University of Rochester Medical Center. Methionine, SAM, SAH, and tHcy concentrations were compared in patients with sepsis versus control participants and in sepsis survivors versus nonsurvivors. Patients with sepsis had significantly higher plasma SAM and SAH concentrations than control participants (SAM: 164 [107-227] vs73 [59-87 nM], P sepsis patients compared to healthy control participants (4 [2-6]) vs 7 [5-9] μM; P = .04). In multivariable analysis, quartiles of SAM, SAH, and tHcy were independently associated with sepsis ( P = .006, P = .05, and P Sepsis nonsurvivors had significantly higher plasma SAM and SAH concentrations than survivors (SAM: 223 [125-260] vs 136 [96-187] nM; P = .01; SAH: 139 [81-197] vs 86 [55-130] nM, P = .006). Plasma tHcy levels were similar in survivors vs nonsurvivors. The associations between SAM or SAH and hospital mortality were no longer significant after adjusting for renal dysfunction. Methionine metabolite concentrations are abnormal in sepsis and linked with clinical outcomes. Further study is required to determine whether these abnormalities have pathophysiologic significance.

  16. Lactic acidosis, hyperlactatemia and sepsis

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Among hospitalized patients, lactic acidosis represents the most common cause of metabolic acidosis. Lactate is not just a metabolic product of anaerobic glycolysis but is triggered by a variety of metabolites even before the onset of anaerobic metabolism as part of an adaptive response to a hypermetabolic state. On the basis of such considerations, lactic acidosis is divided into two classes: inadequate tissue oxygenation (type A and absence of tissue hypoxia (type B. Lactic acidosis is characterized by non-specific symptoms but it should be suspected in all critical patients who show hypovolemic, hypoxic, in septic or cardiogenic shock or if in the presence of an unexplained high anion gap metabolic acidosis. Lactic acidosis in sepsis and septic shock has traditionally been explained as a result of tissue hypoxia when whole-body oxygen delivery fails to meet whole body oxygen requirements. In sepsis lactate levels correlate with increased mortality with a poor prognostic threshold of 4 mmol/L. In hemodynamically stable patients with sepsis, hyperlactatemia might be the result of impaired lactate clearance rather than overproduction. In critically ill patients the speed at which hyperlactatemia resolves with appropriate therapy may be considered a useful prognostic indicator. The measure of blood lactate should be performed within 3 h of presentation in acute care setting. The presence of lactic acidosis requires early identification of the primary cause of shock for the best appropriate treatment. Since most cases of lactic acidosis depend on whole-body oxygen delivery failure, the maximization of systemic oxygen delivery remains the primary therapeutic option. When initial resuscitation does not substantially or completely correct lactic acidosis, it is also essential to consider other causes. The treatment of acidosis with buffering agents (specifically bicarbonate is generally advocated only in the setting of severe acidosis. Ongoing

    Many patients meeting criteria for severe sepsis are not given a sepsis-related diagnosis by emergency physicians (EP). This study 1) compares emergency department (ED) interventions and in-hospital outcomes among patients with severe sepsis, based on the presence or absence of sepsis-related diagnosis, and 2) assesses how adverse outcomes relate to three-hour sepsis bundle completion among patients fulfilling severe sepsis criteria but not given a sepsis-related diagnosis. We performed a retrospective cohort study using patients meeting criteria for severe sepsis at two urban, academic tertiary care centers from March 2015 through May 2015. We included all ED patients with the following: 1) the 1992 Consensus definition of severe sepsis, including two or more systemic inflammatory response syndrome criteria and evidence of organ dysfunction; or 2) physician diagnosis of severe sepsis or septic shock. We excluded patients transferred to or from another hospital and those <18 years old. Patients with an EP-assigned sepsis diagnosis created the "Physician Diagnosis" group; the remaining patients composed the "Consensus Criteria" group. The primary outcome was in-hospital mortality. Secondary outcomes included completed elements of the current three-hour sepsis bundle; non-elective intubation; vasopressor administration; intensive care unit (ICU) admission from the ED; and transfer to the ICU in < 24 hours. We compared proportions of each outcome between groups using the chi-square test, and we also performed a stratified analysis using chi square to assess the association between failure to complete the three-hour bundle and adverse outcomes in each group. Of 418 patients identified with severe sepsis we excluded 54, leaving 364 patients for analysis: 121 "Physician Diagnosis" and 243 "Consensus Criteria." The "Physician Diagnosis" group had a higher in-hospital mortality (12.4% vs 3.3%, P < 0.01) and compliance with the three-hour sepsis bundle (52.1% vs 20.2%, P

    The sepsis syndrome represents a disease continuum, including severe sepsis and septic shock associated with high mortality. One of the main problems in severe sepsis and septic shock, resulting in organ failure and death, are disturbances in the hemostasis due to sepsis-related coagulopathy. Sepsis-related coagulopathy affects not only traditional coagulation factors, but also the platelets and endothelium. Functional testing of the hemostatic system has found application in critical illness. Thrombelastography (TEG) provides an overview of the hemostatic system allowing for an evaluation of interactions between coagulation factors and platelets. Additionally, the role of the endothelium during sepsis can be explored through testing of biomarkers of endothelial damage. The three studies comprising this PhD thesis all investigate important aspects of the disturbed hemostasis during sepsis, including endothelial damage. Together, the specific findings from the three studies improve the existing understanding of sepsis-related coagulopathy, and the possible influences of some of the treatments offered these patients. The first study investigates the occurrence of antimicrobial-induced thrombocytopenia among critically ill patients. In sepsis, thrombocytopenia is a predictor of poor outcome, and reports, of mainly casuistic nature, have previously hypothesized that specific antimicrobial agents could induce in sepsis-related thrombocytopenia. This hypothesis was tested using a randomized designed set-up, encompassing 1147 critically ill patients, and no significant difference in risk of thrombocytopenia was observed among patients receiving large amounts of antimicrobials vs. patients receiving standard-of-care. As a consequence, the risk of antimicrobial-induced thrombocytopenia in the general population of critically ill patients seemingly does not represent a substantial problem and thrombocytopenia during critical illness is most likely due to other factors such

    Background To be able to diagnose and treat sepsis better it is important not only to improve the knowledge about definitions and pathophysiology, but also to gain more insight into specialists' perception of, and attitude towards, the current diagnosis and treatment of sepsis. Methods The study was conducted as a prospective, international survey by structured telephone interview. The subjects were intensive care physicians and other specialist physicians caring for intensive care unit (ICU) patients. Results The 1058 physicians who were interviewed (including 529 intensivists) agreed that sepsis is a leading cause of death on the ICU and that the incidence of sepsis is increasing, but that the symptoms of sepsis can easily be misattributed to other conditions. Physicians were concerned that this could lead to under-reporting of sepsis. Two-thirds (67%) were concerned that a common definition is lacking and 83% said it is likely that sepsis is frequently missed. Not more than 17% agreed on any one definition. Conclusion There is a general awareness about the inadequacy of the current definitions of sepsis. Physicians caring for patients with sepsis recognise the difficulty of defining and diagnosing sepsis and are aware that they miss the diagnosis frequently. PMID:15566585

The available information on sepsis patients is not enough to recommend or to discard the routine evaluation of triglyceride (TG levels at the onset of sepsis. The aim of this study was to investigate the association of hypertriglyceridemia and clinical outcome (or mortality in patients with severe sepsis. Materials and methods: Between January 1 and December 31, 2011, a total of 84 patients with sepsis from the intensive internal care unit at the Kayseri Training and Research Hospital, Kayseri, Turkey, were investigated retrospectively. Sepsis was defined according to the American College of Chest Physicians/Society of Critical Care Medicine/European Society of Intensive Care Medicine consensus conference definitions. For each patient, survival was recorded at the end of the last day of hospitalization as dead or alive. The TG values were taken retrospectively from the records, which were performed routinely for each patient with sepsis at the time of diagnosis. TG >150 mg/dL was considered as hypertriglyceridemia. Results: The percentages of male and female patients were 44% and 56%, respectively. The mean age of patients was 71.49±11.071 years. The percentage of patients with TG values more than 150 mg/dL was 81% (25/31 in the non-survivor group and 19% (6/31 in the survivor group.

    The gastrointestinal tract has long been hypothesized to function as "the motor" of multiple organ dysfunction syndrome. The gastrointestinal microenvironment is comprised of a single cell layer epithelia, a local immune system, and the microbiome. These three components of the intestine together play a crucial role in maintaining homeostasis during times of health. However, the gastrointestinal microenvironment is perturbed during sepsis, resulting in pathologic changes that drive both local and distant injury. In this review, we seek to characterize the relationship between the epithelium, gastrointestinal lymphocytes, and commensal bacteria during basal and pathologic conditions and how the intestinal microenvironment may be targeted for therapeutic gain in septic patients.

This management bundle was advocated by the Scottish Patient Safety Programme as part of its Acute Adult campaign launched in 2008 and adopted by NHS Tayside in 2012. Despite this, the Emergency Department (ED) of Ninewells Hospital, a tertiary referral centre and major teaching hospital in Scotland, was displaying poor success in the Sepsis 6. We therefore set out to improve compliance by evaluating the application of all aspects of the NHS Tayside Sepsis 6 bundle within one hour of ED triage time, to identify what human factors may influence achieving the one hour The Sepsis 6 bundle. This allowed us to tailor a number of specific interventions including educational sessions, regular audit and personal feedback and check list Sepsis 6 sticker. These interventions promoted a steady increase in compliance from an initial rate of 51.0% to 74.3%. The project highlighted that undifferentiated patients create a challenge in initiating the Sepsis 6. Pyrexia is a key human factor-trigger for recognising sepsis with initial nursing assessment being vital in recognition and identifying the best area (resus) of the department to manage severely septic patients. EDs need to recognise these challenges and develop educational and feedback plans for staff and utilise available resources to maximise the Sepsis 6 compliance.

    Care Kumaraswamy and colleagues have investigated whether plasma apolipoprotein M (apoM) is affected during different grades of sepsis, septic shock and systemic inflammatory response syndrome. Interestingly, plasma apoM was significantly decreased in all groups of patients with a relationship...... to severity of disease. This identifies apoM as a potential new biomarker in sepsis. It also underscores the possibility that altered high-density lipoprotein in sepsis patients can affect the course of disease.

    Toll-like receptors are vital transmembrane receptors that initiate the innate immune response to many micro-organisms. The discovery of these receptors has improved our understanding of host-pathogen interactions, and these receptors play an important role in the pathogenesis of multiple neonatal conditions such as sepsis and brain injury. Toll-like receptors, especially TLRs 2 and 4, are associated with necrotizing enterocolitis, periventricular leukomalacia and sepsis.

    The gut is a continuously renewing organ, with cell proliferation, migration and death occurring rapidly under basal conditions. Since the impact of critical illness on cell movement from crypt base to villus tip is poorly understood, the purpose of this study was to determine how sepsis alters enterocyte migration. Wild type, transgenic and knockout mice were injected with 5-bromo-2'deoxyuridine (BrdU) to label cells in S phase before and after the onset of cecal ligation and puncture and were sacrificed at pre-determined endpoints to determine distance proliferating cells migrated up the crypt-villus unit. Enterocyte migration rate was decreased from 24-96 hours following sepsis. BrdU was not detectable on villi 6 days after sham laparotomy, meaning all cells had migrated the length of the gut and been exfoliated into its lumen. However, BrdU positive cells were detectable on villi 10 days after sepsis. Multiple components of gut integrity altered enterocyte migration. Sepsis decreased crypt proliferation, which further slowed enterocyte transit as mice injected with BrdU after the onset of sepsis (decreased proliferation) had slower migration than mice injected with BrdU prior to the onset of sepsis (normal proliferation). Decreasing intestinal apoptosis via gut-specific overexpression of Bcl-2 prevented sepsis-induced slowing of enterocyte migration. In contrast, worsened intestinal hyperpermeability by genetic deletion of JAM-A increased enterocyte migration. Sepsis therefore significantly slows enterocyte migration, and intestinal proliferation, apoptosis and permeability all affect migration time, which can potentially be targeted both genetically and pharmacologically.

    Severe sepsis, a syndrome characterized by systemic inflammation and acute organ dysfunction in response to infection, is a major healthcare problem affecting all age groups throughout the world. Anaesthetists play a central role in the multidisciplinary management of patients with severe sepsis from their initial deterioration at ward level, transfer to the diagnostic imaging suite, and intraoperative management for emergency surgery. The timely administration of appropriate i.v. antimicrobial therapy is a crucial step in the care of patients with severe sepsis who may require surgery to control the source of sepsis. Preoperative resuscitation, aimed at optimizing major organ perfusion, is based on judicious use of fluids, vasopressors, and inotropes. Intraoperative anaesthesia management requires careful induction and maintenance of anaesthesia, optimizing intravascular volume status, avoidance of lung injury during mechanical ventilation, and ongoing monitoring of arterial blood gases, lactate concentration, haematological and renal indices, and electrolyte levels. Postoperative care overlaps with ongoing management of the severe sepsis syndrome patient in the intensive care unit. These patients are by definition, high risk, already requiring multiple supports, and require experienced and skilful decision-making to optimize their chances of a favourable outcome. Similar to acute myocardial infarction, stroke, or acute trauma, the initial hours (golden hours) of clinical management of severe sepsis represent an important opportunity to reduce morbidity and mortality. Rapid clinical assessment, resuscitation and surgical management by a focused multidisciplinary team, and early effective antimicrobial therapy are the key components to improved patient outcome.

    Definitions of sepsis and septic shock were last revised in 2001. Considerable advances have since been made into the pathobiology (changes in organ function, morphology, cell biology, biochemistry, immunology, and circulation), management, and epidemiology of sepsis, suggesting the need for reexamination. To evaluate and, as needed, update definitions for sepsis and septic shock. A task force (n = 19) with expertise in sepsis pathobiology, clinical trials, and epidemiology was convened by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. Definitions and clinical criteria were generated through meetings, Delphi processes, analysis of electronic health record databases, and voting, followed by circulation to international professional societies, requesting peer review and endorsement (by 31 societies listed in the Acknowledgment). Limitations of previous definitions included an excessive focus on inflammation, the misleading model that sepsis follows a continuum through severe sepsis to shock, and inadequate specificity and sensitivity of the systemic inflammatory response syndrome (SIRS) criteria. Multiple definitions and terminologies are currently in use for sepsis, septic shock, and organ dysfunction, leading to discrepancies in reported incidence and observed mortality. The task force concluded the term severe sepsis was redundant. Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. For clinical operationalization, organ dysfunction can be represented by an increase in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score of 2 points or more, which is associated with an in-hospital mortality greater than 10%. Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone.

    Full Text Available Mohammad Rashid Shahidi Bonjar,1 Leyla Shahidi Bonjar2 1School of Dentistry, 2College of Pharmacy, Kerman University of Medical Sciences, Kerman, Iran Abstract: The present paper proposes a prospective auxiliary treatment for sepsis. There exists no record in the published media on the subject. As an auxiliary therapy, efficacious extracorporeal removal of sepsis-causing bacterial antigens and their toxins (BATs from the blood of septic patients is discussed. The principal component to this approach is a bacterial polyvalent antibody-column (BPVAC, which selectively traps wide spectrum of BATs from blood in an extracorporeal circuit, and detoxified blood returns back to the patient’s body. BPVAC treatment would be a device of targeted medicine. Detoxification is performed under supervision of trained personnel using simple blood-circulating machines in which blood circulates from the patient to BPVAC and back to the patient aseptically. BPVACs’ reactive sites consist of carbon nanotubes on which a vast spectra of polyvalent BATs-antibodies are bond to. The devise acts as a biological filter that selectively immobilizes harmful BATs from intoxicated blood; however, no dialysis is involved. For effective neutralization, BPVAC provides large contact surface area with blood. BPVAC approach would have advantages of: 1 urgent neutralization of notorious BATs from blood of septic patients; 2 applicability in parallel with conventional treatments; 3 potential to minimize side effects of the malady; 4 applicability for a vast range of BATs; 5 potential to eliminate contact of BATs with internal tissues and organs; 6 tolerability by patients sensitive to antiserum injections; 7 capability for universal application; 8 affectivity when antibiotic-resistant bacteria are involved and the physician has no or limited access to appropriate antibiotics; and 10 being a single-use, disposable, and stand-alone device.

    Despite advances in supportive care and use of antibiotics, sepsis preserves its importance due to its high mortality and morbidity for neonates. Identifying the causative agents and antibiotic resistance yearly in a neonatal intensive care unit (NICU) helps the physician to choose the most appropriate empirical therapy. In this study we aimed to evaluate positive blood cultures and antibiotic susceptibilities of newborns with proven sepsis during the years 2000-2002 in our NICU. The charts of babies with sepsis were evaluated for clinical characteristics, positive cultures and antimicrobial susceptibilities, retrospectively. Although most of the admitted patients were premature (76.5%), the frequency of proven sepsis was quite low, at 9.1% among 909 newborns. Mortality rate in sepsis was 16%. The most commonly isolated micro-organisms were coagulase-negative staphylococci (CoNS) (31.3%), fungi (19.2%), Staphylococcus aureus (13%) and Klebsiella pneumoniae (10.5%). Methicillin resistance for CoNS was 92.3% and for S. aureus was 72.7%. In the last year, a significant increase in the frequency of Klebsiella pneumoniae (8.3 vs 14.2%), CoNS (27.1 vs 37.1%), Pseudomonas aeruginosa (2.1 vs 8.6%) and fungal infections (18.8 vs 20%) was observed compared to the previous years. An initial empirical antibiotic therapy for late-onset sepsis was designed with teicoplanin + piperacillin-tazobactam/meropenem + antifungal (fluconazole or amphotericin B) as the best combination to cover this spectrum until the culture results arrive. However, this combination is only compatible with our results and may not be applied in all units. Every unit must follow the bacterial spectrum and antibacterial resistance patterns to choose their specific empirical treatment strategy for nosocomial infections.

    This article examines the contemporary knowledge and uncertainties about the burden of pregnancy-associated severe sepsis (PASS), and its manifestations, management, and outcomes. There are relatively sparse data on PASS, related in part to infrequent reports and varying use of terminology and case definitions. PASS remains rare, although its incidence appears to be rapidly rising in some high-resource countries, affecting especially women with limited resources, minorities, and those with chronic illness. High level of clinician vigilance and rapid initiation of appropriate antimicrobial therapy, coupled with effective systemic support for organ dysfunction and correction of occult and overt hypoperfusion are the keys to limit adverse outcomes. However, timely diagnosis and provision of effective care remain a challenge, with reported prevalent delay in recognition and delivery of time-sensitive care interventions among maternal decedents. The mortality rate of PASS has been rising and its case fatality, although relatively low, has remained unchanged, in contrast to the outcome gains in the general population. The long-term sequelae of PASS remain unknown. The relatively limited contemporary data on PASS suggest a rising public health hazard in the obstetric population in high-resource countries, with ongoing challenges in assuring consistent provision of time-sensitive care.

    Full Text Available We sought to create a screening tool with improved predictive value for pediatric severe sepsis and septic shock that can be incorporated into the electronic medical record and actively screen all patients arriving at a pediatric Emergency Department (ED. Gold standard severe sepsis cases were identified using a combination of coded discharge diagnosis and physician chart review from 7,402 children who visited a pediatric ED over two months. The tool’s identification of severe sepsis was initially based on International Consensus Conference on Pediatric Sepsis (ICCPS parameters that were refined by an iterative, virtual process that allowed us to propose successive changes in sepsis detection parameters in order to optimize the tool’s predictive value based on receiver operating curve (ROC characteristics. Age-specific normal and abnormal values for heart rate (HR and respiratory rate (RR were empirically derived from 143,603 children seen in a second pediatric ED over three years. Univariate analyses were performed for each measure in the tool to assess its association with severe sepsis and to characterize it as an early or late indicator of severe sepsis. A split-sample was used to validate the final, optimized tool. The final tool incorporated age-specific thresholds for abnormal HR and RR and employed a linear temperature correction for each category. The final tool’s positive predictive value was 48.7%, a significant, nearly three-fold improvement over the original ICCPS tool. False positive Systemic Inflammatory Response Syndrome (SIRS identifications were nearly six-fold lower.

    Zonulin is a eukaryotic protein structurally similar to Vibrio cholerae's zonula occludens toxin. It plays an important role in the opening of small intestine tight junctions. The loss of gut wall integrity during sepsis might be pivotal and has been described in various experimental as well as human studies. Increased levels of zonulin could be demonstrated in diseases associated with increased intestinal inflammation, such as celiac disease and type 1 diabetes. We therefore investigated the role of plasma levels of zonulin in patients with sepsis as a non-invasive marker of gut wall integrity. Plasma level of zonulin was measured in 25 patients with sepsis, severe sepsis or septic shock according to ACCP/SCCM criteria at the first day of diagnosed sepsis. 18 non-septic post-surgical ICU-patients and 20 healthy volunteers served as control. Plasma levels were determined by using commercially available ELISA kit. Data are given as median and interquartile range (IQR). Significantly higher plasma concentration of zonulin were found in the sepsis group: 6.61 ng/mL (IQR 3.51-9.46), as compared to the to the post-surgical control group: 3.40 ng/mL (IQR 2.14-5.70) (P = 0.025), as well as to the healthy group: 3.55 ng/mL (IQR 3.14-4.14) (P = 0.008). We were able demonstrate elevated levels of plasma zonulin, a potential marker of intestinal permeability in septic patients. Increased zonulin may serve as an additional mechanism for the observed increased intestinal permeability during sepsis and SIRS.

    Rationale: The epidemiology of post–acute care use and hospital readmission after sepsis remains largely unknown. Objectives: To examine the rate of post–acute care use and hospital readmission after sepsis and to examine risk factors and outcomes for hospital readmissions after sepsis. Methods: In an observational cohort study conducted in an academic health care system (2010–2012), we compared post–acute care use at discharge and hospital readmission after 3,620 sepsis hospitalizations with 108,958 nonsepsis hospitalizations. We used three validated, claims-based approaches to identify sepsis and severe sepsis. Measurements and Main Results: Post–acute care use at discharge was more likely after sepsis, driven by skilled care facility placement (35.4% after sepsis vs. 15.8%; P Readmission rates at 7, 30, and 90 days were higher postsepsis (P readmission risk was present regardless of sepsis severity (27.3% after sepsis and 26.0–26.2% after severe sepsis). After controlling for presepsis characteristics, the readmission risk was found to be 1.51 times greater (95% CI, 1.38–1.66) than nonsepsis hospitalizations. Readmissions after sepsis were more likely to result in death or transition to hospice care (6.1% vs. 13.3% after sepsis; P readmissions after sepsis hospitalizations included age, malignancy diagnosis, hospitalizations in the year prior to the index hospitalization, nonelective index admission type, one or more procedures during the index hospitalization, and low hemoglobin and high red cell distribution width at discharge. Conclusions: Post–acute care use and hospital readmissions were common after sepsis. The increased readmission risk after sepsis was observed regardless of sepsis severity and was associated with adverse readmission outcomes. PMID:25751120

    Intestinal barrier dysfunction is thought to contribute to the development of multiple organ dysfunction syndrome in sepsis. Although there are similarities in clinical course following sepsis, there are significant differences in the host response depending on the initiating organism and time course of the disease, and pathways of gut injury vary widely in different preclinical models of sepsis. The purpose of this study was to determine whether the timecourse and mechanisms of intestinal barrier dysfunction are similar in disparate mouse models of sepsis with similar mortalities. FVB/N mice were randomized to receive cecal ligation and puncture (CLP) or sham laparotomy, and permeability was measured to fluoresceinisothiocyanate conjugated-dextran (FD-4) six to 48 h later. Intestinal permeability was elevated following CLP at all timepoints measured, peaking at 6 to 12 h. Tight junction proteins claudin 1, 2, 3, 4, 5, 7, 8, 13, and 15, Junctional Adhesion Molecule-A (JAM-A), occludin, and ZO-1 were than assayed by Western blot, real-time polymerase chain reaction, and immunohistochemistry 12 h after CLP to determine potential mechanisms underlying increases in intestinal permeability. Claudin 2 and JAM-A were increased by sepsis, whereas claudin-5 and occludin were decreased by sepsis. All other tight junction proteins were unchanged. A further timecourse experiment demonstrated that alterations in claudin-2 and occludin were detectable as early as 1 h after the onset of sepsis. Similar experiments were then performed in a different group of mice subjected to Pseudomonas aeruginosa pneumonia. Mice with pneumonia had an increase in intestinal permeability similar in timecourse and magnitude to that seen in CLP. Similar changes in tight junction proteins were seen in both models of sepsis although mice subjected to pneumonia also had a marked decrease in ZO-1 not seen in CLP. These results indicate that two disparate, clinically relevant models of sepsis

    Mortality of severe sepsis remains at 40% to 50%. Intensive efforts over the past two decades have only marginally improved outcome. Improving outcome in sepsis depends on understanding its pathophysiology, which involves triggers, responses of the organism, and dysfunction. Stress, injury, or infection trigger host responses, including local and systemic orchestrated mechanisms. Dysfunction and outcome depend on both trigger and response. Blood coagulation, inflammation, immunity, and fibrinolysis are critical components of the organism's responses. Understanding their role in sepsis pathophysiology is the key to effective treatment. Relevant studies were identified by a systematic literature search, complemented by manual search of individual citations. Using PubMed, 'sepsis' yields more than 62,000 references, 'plasminogen activators' more than 21,000. The selection of citations was guided by preference for reviews that expand important threads of argumentation. Single original studies were included when relevant to critical points. This analytical review describes the essential elements of pathophysiology and the current status of sepsis treatment. Based on this context, an emerging therapeutic option will be discussed: plasminogen activators.

    Sepsis mortality may be improved by early recognition and appropriate treatment based on evidence-based guidelines. An intervention was developed that focused on earlier identification of sepsis, early antimicrobial administration, and an educational program that was disseminated throughout all hospital units and services. There were 1331 patients with sepsis during the intervention period and 1401 patients with sepsis during the control period. After controlling for expected mortality, patients in the intervention period had 30% lower odds of dying (odds ratio = 0.70, 95% confidence interval [CI] = 0.57 to 0.84). They also had 1.07 fewer days on average in the intensive care unit (95% CI = -1.98 to -0.16), 2.15 fewer hospital days (95% CI = -3.45 to -0.86), and incurred on average $1949 less in hospital costs, although the effect on costs was not statistically significant. Continued incremental improvement and sustainment is anticipated through organizational oversight, continued education, and initiation of an automated electronic sepsis alert function. © The Author(s) 2014.

    Full Text Available Las miopatías inflamatorias son un grupo de enfermedades caracterizadas por debilidad muscular proximal y las causas mayores incluyen la polimiositis (PM, dermatomiositis y miositis por cuerpos de inclusión. Las complicaciones respiratorias son comunes y adquieren importancia por la incidencia sobre el pronóstico. Las tres formas de compromiso frecuentes son la enfermedad pulmonar intersticial, la neumopatía aspirativa y la incapacidad ventilatoria (IV por debilidad de los músculos respiratorios, que en su forma severa es de ocurrencia excepcional. Se presenta una paciente con IV sin compromiso del parénquima pulmonar, que requirió asistencia respiratoria mecánica por 4 meses con «destete» exitoso.The inflammatory diseases of muscle are a group of disorders characterized by proximal muscle weakness. Most cases fall into three major diagnostic categories, polymyositis (PM, dermatomyositis and inclusion body myositis. Respiratory complications are a common feature and are an important cause of morbidity and mortality. The three main types of pulmonary involvement are interstitial lung disease, aspiration pneumonia and ventilatory incapacity (VI due to muscle weakness. There are few reported cases in which mechanical ventilation has been used in patients with PM and VI in absense of lung disease. We present a patient with PM and VI due to muscle weakness who underwent therapy maintenance with mechanical ventilator and was weaned 4 months later.

    Based on recent clinical, epidemiological, and pathophysiological data, a third international consensus conference was carried out to define new criteria of sepsis in February 2016. This review presents the different items of this new definition, their limitations and their contribution to research and diagnosis of sepsis, in comparison with the previous definitions. Incidence, management, and pathophysiological knowledge of sepsis have improved over the past 20 years. However, sepsis still evolves to a mortal outcome, in one case out of five, with no new recent or specific therapy showing its efficacy on the patient's prognosis. These findings have led to the development of new definition. The new definition of sepsis incorporates relevant clinical and biological criteria such as SOFA score or serum lactate levels. It no longer takes into account the items of the systemic inflammatory response syndrome, which present a lack of specificity. It also simplifies the different stages of severity by deleting the term of 'severe sepsis' and by defining septic shock as a subset of sepsis. This definition, endorsed by only two international societies of intensive care, has some limitations and so merits prospective validation at different levels.

    This work presents the role of Gram-negative bacteria endotoxins, pro- and anti-inflammatory cytokines and reactive oxygen species (ROS) in the complex and not fully explained pathogenesis of sepsis. The so-called "respiratory burst" of neutrophils and the antioxidant mechanisms of the host are also discussed. The work focuses on possible approaches to the management of sepsis connected with immunotherapy. Neutralization of endotoxin lipopolysaccharide (LPS), anti-tumor necrosis factor alpha (TNF-alpha) therapy with monoclonal antibodies or pentoxifylline (PTXF), as well as soluble recombinant cytokine agonists and antagonists used in clinical trials are taken into consideration. In addition, cytokine manipulation therapy, anti-adhesion techniques, glucocorticoides and antioxidant barrier interference are also described. So far there has been no immunotherapy of sepsis in children of proven clinical efficacy, which prompts an aggressive examination of the immune system aimed at affecting its function.

    Sepsis is a clinical syndrome that results from the dysregulated inflammatory response to infection that leads to organ dysfunction. The resulting losses to society in terms of financial burden, morbidity, and mortality are enormous. We provide a review of sepsis, its underlying pathophysiology, and guidance for diagnosis and management of this common disease. Current established treatments include appropriate antimicrobial agents to target the underlying infection, optimization of intravascular volume to improve stroke volume, vasopressors to counteract vasoplegic shock, and high-quality supportive care. Appropriate implementation of established treatments combined with novel therapeutic approaches promises to continue to decrease the impact of this disease.

    IMPORTANCE The Third International Consensus Definitions Task Force defined sepsis as “life-threatening organ dysfunction due to a dysregulated host response to infection.” The performance of clinical criteria for this sepsis definition is unknown. OBJECTIVE To evaluate the validity of clinical criteria to identify patients with suspected infection who are at risk of sepsis. DESIGN, SETTINGS, AND POPULATION Among 1.3 million electronic health record encounters from January 1, 2010, to December 31, 2012, at 12 hospitals in southwestern Pennsylvania, we identified those with suspected infection in whom to compare criteria. Confirmatory analyses were performed in 4 data sets of 706 399 out-of-hospital and hospital encounters at 165 US and non-US hospitals ranging from January 1, 2008, until December 31, 2013. EXPOSURES Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score, systemic inflammatory response syndrome (SIRS) criteria, Logistic Organ Dysfunction System (LODS) score, and a new model derived using multivariable logistic regression in a split sample, the quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA) score (range, 0–3 points, with 1 point each for systolic hypotension [≤100 mm Hg], tachypnea [≥22/min], or altered mentation). MAIN OUTCOMES AND MEASURES For construct validity, pairwise agreement was assessed. For predictive validity, the discrimination for outcomes (primary: in-hospital mortality; secondary: in-hospital mortality or intensive care unit [ICU] length of stay ≥3 days) more common in sepsis than uncomplicated infection was determined. Results were expressed as the fold change in outcome over deciles of baseline risk of death and area under the receiver operating characteristic curve (AUROC). RESULTS In the primary cohort, 148 907 encounters had suspected infection (n = 74 453 derivation; n = 74 454 validation), of whom 6347 (4%) died.

    Conclusion: Resistin levels were higher in premature newborns with sepsis and correlated with IL-6 levels, which is an indicator of neonatal sepsis. This suggests that resistin may also be used in the diagnosis of neonatal sepsis. However, it has limited value when compared with the other inflammatory markers including C-reactive protein, procalcitonin, and IL-6.

    Las infecciones constituyen una de las principales causas de muerte en el periodo neonatal. El diagnóstico de sepsis neonatal representa un gran desafío ya que los recién nacidos presentan signos clínicos muy inespecíficos y los exámenes auxiliares tienen una baja sensibilidad. Con el objetivo de mejorar el diagnóstico correcto de esta patología proponemos un algoritmo de vigilancia diagnóstica para sepsis neonatal tardía en el Perú y países de la región. El algoritmo permite clasificar a los episodios como sepsis confirmada, probable o posible, y sobretodo busca identificar aquellos episodios que no corresponden a sepsis, evitando calificar otras patologías como “sepsis”. Un mejor diagnóstico permitiría tener tasas más reales de sepsis neonatal, mejorar el uso de antibióticos y evitar sus efectos negativos en el recién nacido, así como una visión más exacta de su impacto en la salud pública.

    Sepsis-induced suppression in T-cell proliferation follows deranged Ca(2+) signaling in adult rats. In preliminary studies, we observed suppression in T-cell proliferation in septic neonatal rats as well. In this study, we assessed splenic T-cell cytosolic Ca(2+) concentration, [Ca(2+)](i), as its elevation plays an important role in T-cell proliferation. Also, we investigated the role of PGE(2) in sepsis-related changes in T-cell [Ca(2+)](i) in animals pretreated with cyclooxygenase-1 (COX-1) inhibitor (resveratrol) and cyclooxygenase-2 (COX-2) inhibitor (NS-398). Sepsis was induced in 15-day-old rat pups by intraperitoneal implantation of fecal pellets containing Escherichia coli and Bacteroides fragilis. The sham group consisted of pups implanted with sterile fecal pellets. Septic and sham pups were sacrificed 24 h after implantation and their spleens were removed. The spleens from sham and septic pups, along with spleens from unoperated control pups, were processed for single cell suspensions, and T cells were isolated using nylon wool columns. Fura-2 fluorophotometry was employed for the measurement of [Ca(2+)](i) (in nM units) in T cells stimulated with concanavalin A (ConA). Our results show that ConA-mediated T-cell [Ca(2+)](i) response is significantly suppressed in septic neonatal rats. Pretreatment of pups with COX-2, but not COX-1 inhibitor, prevented the decrease in the [Ca(2+)](i) response. These findings suggest that PGE(2) might induce the attenuation in T-cell Ca(2+) signaling during sepsis in neonatal rats. Copyright 2001 S. Karger AG, Basel

    Microglial polarization in response to brain inflammatory conditions is a crescent field in neuroscience. However, the effect of systemic inflammation, and specifically sepsis, is a relatively unexplored field that has great interest and relevance. Sepsis has been associated with both early and late harmful events of the central nervous system, suggesting that there is a close link between sepsis and neuroinflammation. During sepsis evolution it is supposed that microglial could exert both neurotoxic and repairing effects depending on the specific microglial phenotype assumed. In this context, here it was reviewed the role of microglial polarization during sepsis-associated brain dysfunction. Copyright © 2017 Elsevier B.V. All rights reserved.

    Sepsis is an acute systemic inflammatory disease. Glucocorticoids (GCs), which function by binding to the GC receptor GR have very powerful anti-inflammatory activities, yet they are hardly useful in sepsis. We can thus consider sepsis as a GC resistant disease. We here review the literature which has investigated this GC resistance, and summarize the mechanisms of GC resistance that have been observed in other diseases and in experimental models. We also discuss the importance of GC resistance in sepsis, in terms of the contribution of this phenomenon to the pathogenesis of sepsis. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Neutrophil migration under normal and sepsis conditions.

    Science.gov (United States)

    2015-01-01

    Neutrophil migration is critical for pathogen clearance and host survival during severe sepsis. Interaction of neutrophil adhesion receptors with ligands on endothelial cells results in firm adhesion of the circulating neutrophils, followed by neutrophil activation and directed migration to sites of infection through the basement membrane and interstitial extracellular matrix. Proteolytic enzymes and reactive oxygen species are produced and released by neutrophils in response to a variety of inflammatory stimuli. Although these mediators are important for host defense, they also promote tissue damage. Excessive neutrophil migration during the early stages of sepsis may lead to an exaggerated inflammatory response with associated tissue damage and subsequent organ dysfunction. On the other hand, dysregulation of migration and insufficient migratory response that occurs during the latter stages of severe sepsis contributes to neutrophils' inability to contain and control infection and impaired wound healing. This review discusses the major steps and associated molecules involved in the balance of neutrophil trafficking, the precise regulation of which during sepsis spells life or death for the host.

    Full Text Available Abstract Background Sepsis (bloodstream infection is the leading cause of death in non-surgical intensive care units. It is diagnosed in 750,000 US patients per annum, and has high mortality. Current understanding of sepsis is predominately observational and correlational, with only a partial and incomplete understanding of the physiological dynamics underlying the syndrome. There exists a need for dynamical models of sepsis progression, based upon basic physiologic principles, which could eventually guide hourly treatment decisions. Results We present an initial mathematical model of sepsis, based on metabolic rate theory that links basic vascular and immunological dynamics. The model includes the rate of vascular circulation, a surrogate for the metabolic rate that is mechanistically associated with disease progression. We use the mass-specific rate of blood circulation (SRBC, a correlate of the body mass index, to build a differential equation model of circulation, infection, organ damage, and recovery. This introduces a vascular component into an infectious disease model that describes the interaction between a pathogen and the adaptive immune system. Conclusion The model predicts that deviations from normal SRBC correlate with disease progression and adverse outcome. We compare the predictions with population mortality data from cardiovascular disease and cancer and show that deviations from normal SRBC correlate with higher mortality rates.

    Sepsis is one of the biggest challenges in critical care nowadays. Defining sepsis is a difficult task on its own and its diagnosis and treatment requires well trained, devoted personnel with interdisciplinary collaboration in order to provide the patients the best chance for survival. Immediate resuscitation, early adequate antimicrobial therapy, source control and highly sophisticated organ support on the intensive care units are all inevitable necessities for successful recovery. To help fast and accurate diagnosis biomarkers have been measured for decades. Procalcitonin (PCT) is one of the most studied, but the results are conflicting. Sepsis means a very loose cohort of a large heterogeneous patient population, hence defining certain cut off values for PCT to differentiate between different severities of the disease is almost impossible. Clinicians first have to understand the pathophysiological background of sepsis to be able to interpret correctly the PCT results. Nevertheless, PCT has been shown to have the best sensitivity and specificity to indicate infection, antibiotic appropriateness and stopping therapy. In this article we will focus on some important aspects of pathophysiology and advice on how to implement that in the everyday clinical practice. We believe that this multimodal evaluation of the clinical picture together with PCT results can be a useful tool to make the most out of the PCT results, and do the best for patients on the ICU.

    Critical illness is characterized by oxidative stress which leads to multiple organ failure, and sepsis-related organ dysfunction remains the most common cause of death in the intensive care unit. Over the last 2 decades, different antioxidant therapies have been developed to improve outcomes in septic patients. According to recent evidence, selenium therapy should be considered the cornerstone of the antioxidant strategies. Selenium given as selenious acid or sodium selenite should be considered as a drug or pharmaconutrient with prooxidant and cytotoxic effects when a loading dose in intravenous bolus form is administered, particularly in the early stage of severe sepsis/septic shock. To date, several phase ii trials have demonstrated that selenium therapy may be able to decrease mortality, improve organ dysfunction and reduce infections in critically ill septic patients. The effect of selenium therapy in sepsis syndrome must be confirmed by large, well designed phase iii clinical trials. The purpose of this review is to discuss current evidence on selenium pharmaconutrition in sepsis syndrome. Copyright © 2013 Elsevier España, S.L. and SEMICYUC. All rights reserved.

    Sepsis can increase the amount of triglyceride as well as change the functional and structural components of lipoproteins. The triglyceride level is directly proportional to the severity of sepsis and associated with a systemic inflammatory response. The study aims to determine the correlation between the severity of bacterial sepsis with triglyceride value. An observational study with case control design from January2017 to March 2017 in 30 sepsis and 30 non-sepsis patients at H. Adam Malik General Hospital Medan. We examined Procalcitonin (PCT) and triglyceride level on the 1st, 3rd and 5th day and then analyzed using MannWhitney to assess their correlation.The triglyceride value in the sepsis group was 120 ± 5.1 mg/dl on day 1, non-sepsis 117.53 ± 36.37mg/dl. However, on the fifth day, the sepsis group of triglyceride values was 124.2±50.29mg/dl and the non-sepsis group triglyceride values 134.03±68.12mg/dl. There was no specific connection between the severity of sepsis and triglyceride value in a patient with sepsis.

    Neutrophils are key effectors in the host's immune response to sepsis. Excessive stimulation or dysregulated neutrophil functions are believed to be responsible for sepsis pathogenesis. However, the mechanisms regulating functional plasticity of neutrophils during sepsis have not been fully determined. We investigated the role of autophagy in neutrophil functions during sepsis in patients with community-acquired pneumonia. Neutrophils were isolated from patients with sepsis and stimulated with phorbol 12-myristate 13-acetate (PMA). The levels of reactive oxygen species generation, neutrophil extracellular trap (NET) formation, and granule release, and the autophagic status were evaluated. The effect of neutrophil autophagy augmentation was further evaluated in a mouse model of sepsis. Neutrophils isolated from patients who survived sepsis showed an increase in autophagy induction, and were primed for NET formation in response to subsequent PMA stimulation. In contrast, neutrophils isolated from patients who did not survive sepsis showed dysregulated autophagy and a decreased response to PMA stimulation. The induction of autophagy primed healthy neutrophils for NET formation and vice versa. In a mouse model of sepsis, the augmentation of autophagy improved survival via a NET-dependent mechanism. These results indicate that neutrophil autophagy primes neutrophils for increased NET formation, which is important for proper neutrophil effector functions during sepsis. Our study provides important insights into the role of autophagy in neutrophils during sepsis.

    IMPORTANCE Definitions of sepsis and septic shock were last revised in 2001. Considerable advances have since been made into the pathobiology (changes in organ function, morphology, cell biology, biochemistry, immunology, and circulation), management, and epidemiology of sepsis, suggesting the need for reexamination. OBJECTIVE To evaluate and, as needed, update definitions for sepsis and septic shock. PROCESS A task force (n = 19) with expertise in sepsis pathobiology, clinical trials, and epidemiology was convened by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. Definitions and clinical criteria were generated through meetings, Delphi processes, analysis of electronic health record databases, and voting, followed by circulation to international professional societies, requesting peer review and endorsement (by 31 societies listed in the Acknowledgment). KEY FINDINGS FROMEVIDENCE SYNTHESIS Limitations of previous definitions included an excessive focus on inflammation, the misleading model that sepsis follows a continuum through severe sepsis to shock, and inadequate specificity and sensitivity of the systemic inflammatory response syndrome (SIRS) criteria. Multiple definitions and terminologies are currently in use for sepsis, septic shock, and organ dysfunction, leading to discrepancies in reported incidence and observed mortality. The task force concluded the term severe sepsis was redundant. RECOMMENDATIONS Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. For clinical operationalization, organ dysfunction can be represented by an increase in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score of 2 points or more, which is associated with an in-hospital mortality greater than 10%. Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a

    Full Text Available Sepsis is a complication of severe infection associated with high mortality and open diagnostic issues. Treatment strategies are currently limited and essentially based on prompt recognition, aggressive supportive care and early antibiotic treatment. In the last years, extensive antibiotic use has led to selection, propagation and maintenance of drug-resistant microorganisms. In this context, several biomarkers have been proposed for early identification, etiological definition, risk stratification and improving antibiotic stewardship in septic patient care. Among these molecules, only a few have been translated into clinical practice. In this review, we provided an updated overview of established and developing biomarkers for sepsis, focusing our attention on their pathophysiological profile, advantages, limitations, and appropriate evidence-based use in the management of septic patients.

    Tension-free vaginal tape (TVT), is a commonly performed, low risk procedure for treatment of stress urinary incontinence (SUI). Severe complications are rare, but can be potentially life threatening. We present a case of 66 year old patient who sustained bladder perforation at the time of TVT procedure and subsequently developed sepsis rapidly leading to multi-organ failure and triggering sequence of serious complications. During her inpatient stay she required ITU admission, emergency laparotomy, TVT mesh removal, bowel resection due to ischemic colitis and anticoagulation for pulmonary embolism. Despite of clinical picture of sepsis her microbiology tests were almost consistently negative. This case emphasise importance of awareness and quick recognition of TVT related complications. Patient ultimately survived and recovered thanks to timely and coordinated management by the multidisciplinary team of doctors.

The limited knowledge of the pathophysiology in association with the lack of in vitro diagnostic methods for the certain and quick determination of the causative microbiological agents and their antibiotic resistance means the condition is still critical and of high impact in health care. The current gold standard method to detect the sepsis-causing pathogens, which is based on blood culture, is still insufficiently sensitive and slow. The new culture-independent molecular biology-based techniques can lead to the identification of a broad range of microorganisms and resistance markers within a few hours and with high sensitivity and specificity; nevertheless, limitations of, for example, the polymerase chain reaction-based methods still hamper their application in the clinical routine. This review summarizes the in vitro diagnostic methods and their approach in the clinical diagnosis of the bloodstream infections, and explores their advantages and disadvantages at the current state of the art. A quick analysis of the future prospective in multiplex technologies for microbiological diagnosis of sepsis is also provided. Keywords: PCR, PCR/ESI-MS, microarray, MALDI-TOF, next

    Full Text Available Over the past decade, sepsis has been diagnosed according to consensus guidelines established in 1991 as an infection in addition to the symptoms of systemic inflammatory response syndrome (SIRS. In addition to the previous criteria, the 2001 conference added several new diagnostic criteria for sepsis. Of particular interest was the inclusion of the biomarkers procalcitonin (PCT and C-reactive protein (CRP, despite the overall conclusion that it was premature to use biomarkers for sepsis diagnosis. The primary recommendation of the panel was the implementation of the Predisposition, insult Infection, Response, and Organ dysfunction (PIRO.The immune system has traditionally been devided into innate and adaptive components, each of which has a different role and function in defending the host against infectious agents. Stimulation of different TLRs induces distinct patterns of gene expression, which not only leads to the activation of innate immunity but also increasing evidence supports an additional critical role for TLRs in orchestrating the development of adaptive immune responses. The superantigens are able to induce toxic shock syndrome and can sometimes cause multiple organ failure via adaptive immune system. The superantigenic activity of the bacterial exotoxins can be attributed to their ability to cross-link major histocompatibility complex class II molecules on antigen-presenting cells outside the peptide groove with T-cell receptors to form a trimolecular complex. This trimolecular interaction leads to uncontrolled release of a number of proinflammatory cytokines. Proinflammatory cytokines especially IFN-γ and TNF-α, the key cytokines causing toxic shock syndrome. KEYWORDS: sepsis, innate immunity, adaptive.

    The aim of our study was to analyze clinical and biological characteristics of immunocompromised patients with staphylococcal sepsis and to compare with the same data in non-immunocompromised patients. The diagnosis of sepsis was made based on Bone criteria. MiniAPI system ID 32 STAPH was used for identification and antibiotic susceptibility was assessed by ATB STAPH method and by E-test for oxacillin and vancomycin. Among the 147 patients with Staphylococcus aureus sepsis--66.67% had concomitant immunosuppressive conditions (diabetes mellitus, liver diseases, renal failure, corticotherapy, etc). We have found a significant correlation between the immunosuppressed status and MRSA (methicillin-resistant Staphylococcus aureus) involvement (p = 0.0018) and also, between this group of patients and treatment failure (p = 0.0012). Because of the high rate of MRSA involvement in systemic infections in the Eastern region of Romania first intention treatment of patients with staphylococcal infections and conditions of immunosuppression must include antibiotics effective against methicillin-resistant strains.

    Clostridium septicum is an unusual anaerobic, gram-positive, gas-producing bacillus, which has been identified as a cause of fulminant rapidly fatal infection in humans. Infection with C. septicum usually occurs in patients with cancer, patients receiving immunosuppressive chemotherapy, or patients with a nonmalignant hematological disorder such as hemolytic uremic syndrome. C. septicum infection most commonly involves the abdomen, and a recent review article has identified 164 cases in the medical literature describing the abdominal findings in this disease. Intracranial manifestation of C. septicum infection are less common and include meningitis, cerebritis, abscess formation and pneumocephalus. There have been only 12 documented cases in the English literature describing central nervous system lesions associated with C. septicum. We present a case report of a 56-year-old man in whom septicemia due to C. septicum developed as a complication of Crohn's disease. To our knowledge, there has never been a previous report of C. septicum sepsis related to underlying Crohn's disease. Our case is also remarkable in that an intracerebral gas collection developed at the site of a mycotic infarct related to C. septicum bacteremia, Intracranial, intraparenchymal gas formation related to anaerobic infection is extremely rare; to our knowledge, this radiological finding related to C. septicum sepsis has been described in only 1 previous case report in the medical literature. We also describe the intra-abdominal manifestations of C. septicum sepsis that occurred in this patient as well as the associated radiographic and pathologic findings. (author)

Esta molécula es liberada de la bacteria a la circulación exhibiendo una amplia variedad de efectos tóxicos y pro-inflamatorios, los cuales están asociados al lípido A y a su vez están relacionados a la patogénesis de la sepsis. Muchos de los fenómenos fisiológicos producidos por el LPS resultan de la capacidad de esta molécula de activar las células del sistema inmune del huésped, entre ellas monocitos, macrófagos y leucocitos polimorfonucleares. Este proceso produce una inflamación local, proceso beneficioso para el huésped. Sin embargo, si la cantidad de LPS liberado excede cierta concentración crítica umbral, la exacerbada liberación de citoquinas inflamatorias como Factor de Necrosis Tumoral (TNF-a e interleuquinas (IL resulta en sepsis grave, lo que hace necesario encontrar nuevas opciones terapéuticas capaces de neutralizar la endotoxina circulante.

    Full Text Available BACKGROUND Sepsis refers to the systemic response to serious infection. It can be response to the infection caused by any class of microorganism. The presence of bacteraemia is an indicator of disseminated infection and generally indicates a poorer prognosis when associated with localised disease. This study was undertaken to study the diagnostic and prognostic value of Procalcitonin (PCT in patients with sepsis. AIM To study the diagnostic and prognostic value of Procalcitonin (PCT in patients with sepsis. MATERIALS AND METHODS Fifty patients of age more than 18 years with sepsis admitted in KMC Hospitals, Mangalore, from August 2008 to June 2010 were subjects in the study after due permission from institution and informed consent from the patients. Diagnosis of sepsis was made according to criteria by ACCP/SCCM definition for sepsis. Definitive aetiological diagnosis requires isolation of microorganism from the blood and local site of infection, Gram stain and culture of the material from the primary site of infection for the microbial aetiology was taken. Other appropriate laboratory investigations depending upon requirement were done as mentioned in the investigations. RESULTS Out of total 50 patients, 23 patients were in group of sepsis, 14 were in group of severe sepsis while 13 had septic shock. Maximum number of the study patients were in the age group of 51-60 years. 52% of the study patients were male and 48% were female. Most common symptom in patients with sepsis was fever. Most common sign in the patient with sepsis is tachycardia followed by high temperature and then tachypnoea. Most common source of sepsis was respiratory infection followed by UTI. CONCLUSION Our data suggest the possibility that the addition of Procalcitonin into the standard workup of critically ill patients with suspected sepsis could increase diagnostic certainty and improve patient management.

    To provide an update to "Surviving Sepsis Campaign Guidelines for Management of Sepsis and Septic Shock: 2012." A consensus committee of 55 international experts representing 25 international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict-of-interest (COI) policy was developed at the onset of the process and enforced throughout. A stand-alone meeting was held for all panel members in December 2015. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development. The panel consisted of five sections: hemodynamics, infection, adjunctive therapies, metabolic, and ventilation. Population, intervention, comparison, and outcomes (PICO) questions were reviewed and updated as needed, and evidence profiles were generated. Each subgroup generated a list of questions, searched for best available evidence, and then followed the principles of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to assess the quality of evidence from high to very low, and to formulate recommendations as strong or weak, or best practice statement when applicable. The Surviving Sepsis Guideline panel provided 93 statements on early management and resuscitation of patients with sepsis or septic shock. Overall, 32 were strong recommendations, 39 were weak recommendations, and 18 were best-practice statements. No recommendation was provided for four questions. Substantial agreement exists among a large cohort of international experts regarding many strong recommendations for the best care of patients with sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for these critically ill patients with high mortality.

    In accordance with Rory's Regulations, hospitals across New York State developed and implemented protocols for sepsis recognition and treatment to reduce variations in evidence informed care and preventable mortality. The New York Department of Health sought to develop a risk assessment model for accurate and standardized hospital mortality comparisons of adult septic patients across institutions using case-mix adjustment. Retrospective evaluation of prospectively collected data. Data from 43,204 severe sepsis and septic shock patients from 179 hospitals across New York State were evaluated. Prospective data were submitted to a database from January 1, 2015, to December 31, 2015. None. Maximum likelihood logistic regression was used to estimate model coefficients used in the New York State risk model. The mortality probability was estimated using a logistic regression model. Variables to be included in the model were determined as part of the model-building process. Interactions between variables were included if they made clinical sense and if their p values were less than 0.05. Model development used a random sample of 90% of available patients and was validated using the remaining 10%. Hosmer-Lemeshow goodness of fit p values were considerably greater than 0.05, suggesting good calibration. Areas under the receiver operator curve in the developmental and validation subsets were 0.770 (95% CI, 0.765-0.775) and 0.773 (95% CI, 0.758-0.787), respectively, indicating good discrimination. Development and validation datasets had similar distributions of estimated mortality probabilities. Mortality increased with rising age, comorbidities, and lactate. The New York Sepsis Severity Score accurately estimated the probability of hospital mortality in severe sepsis and septic shock patients. It performed well with respect to calibration and discrimination. This sepsis-specific model provides an accurate, comprehensive method for standardized mortality comparison of adult

Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for these critically ill patients with high mortality.

    Objective: To observe the effect of sepsis single-disease manage system on the improvement of sepsis treatment and the value in predicting mortality in patients with sepsis. Methods: A retrospective study was conducted. Patients with sepsis admitted to the Department of Surgical Intensive Care Unit of Sun Yat-Sen University First Affiliated Hospital from September 22, 2013 to May 5, 2015 were enrolled in this study. Sepsis single-disease manage system (Rui Xin clinical data manage system, China data, China) was used to monitor 25 clinical quality parameters, consisting of timeliness, normalization and outcome parameters. Based on whether these quality parameters could be completed or not, the clinical practice was evaluated by the system. The unachieved quality parameter was defined as suspicious parameters, and these suspicious parameters were used to predict mortality of patients with receiver operating characteristic curve (ROC). Results: A total of 1 220 patients with sepsis were enrolled, included 805 males and 415 females. The mean age was (59±17) years, and acute physiology and chronic health evaluation (APACHE Ⅱ) scores was 19±8. The area under ROC curve of total suspicious numbers for predicting 28-day mortality was 0.70; when the suspicious parameters number was more than 6, the sensitivity was 68.0% and the specificity was 61.0% for predicting 28-day mortality. In addition, the area under ROC curve of outcome suspicious number for predicting 28-day mortality was 0.89; when the suspicious outcome parameters numbers was more than 1, the sensitivity was 88.0% and the specificity was 78.0% for predicting 28-day mortality. Moreover, the area under ROC curve of total suspicious number for predicting 90-day mortality was 0.73; when the total suspicious parameters number was more than 7, the sensitivity was 60.0% and the specificity was 74.0% for predicting 90-day mortality. Finally, the area under ROC curve of outcome suspicious numbers for predicting 90

    Full Text Available Sepsis, a dysregulated host response to infection that causes life-threatening organ dysfunction, is a highly heterogeneous syndrome with no specific treatment. Although sepsis can be caused by a wide variety of pathogenic organisms, endothelial dysfunction leading to vascular leak is a common mechanism of injury that contributes to the morbidity and mortality associated with the syndrome. Perturbations to the angiopoietin (Ang/Tie2 axis cause endothelial cell activation and contribute to the pathogenesis of sepsis. In this review, we summarize how the Ang/Tie2 pathway is implicated in sepsis and describe its prognostic as well as therapeutic utility in life-threatening infections.

    Sepsis after hip fracture typically develops from one of the 3 potential infectious sources: urinary tract infection (UTI), pneumonia, and surgical site infection (SSI). The purpose of this investigation is to determine (1) the proportion of cases of sepsis that arises from each of these potential infectious sources; (2) baseline risk factors for developing each of the potential infectious sources; and (3) baseline risk factors for developing sepsis. The National Surgical Quality Improvement Program database was searched for geriatric patients (aged >65 years) who underwent surgery for hip fracture during 2005-2013. Patients subsequently diagnosed with sepsis were categorized according to concomitant diagnosis with UTI, SSI, and/or pneumonia. Multivariate regression was used to test for associations while adjusting for baseline characteristics. Among the 466 patients who developed sepsis (2.4% of all patients), 157 (33.7%) also had a UTI, 135 (29.0%) also had pneumonia, and 36 (7.7%) also had SSI. The rate of sepsis was elevated in patients who developed UTI (13.0% vs 1.7%; P sepsis (21.0% vs 3.8%; P Sepsis occurs in about 1 in 40 patients after geriatric hip fracture surgery. Of these septic cases, 1 in 3 is associated with UTI, 1 in 3 with pneumonia, and 1 in 15 with SSI. The cause of sepsis is often unknown on clinical diagnosis, and this distribution of potential infectious sources allows clinicians for direct identification and treatment.

    Full Text Available Sepsis is a common complication after severe trauma and burn, and also one of the main causes of death. Recently, although some new progresses were seen in antibiotic therapy, the mortality of sepsis is still on the rise, and the death rate as a result of sepsis is higher than a total of that of prostate cancer, breast cancer and AIDS. Therefore, sepsis has obviously become one of the serious ailments threatening human health. The present paper introduced the international definition of sepsis, severe sepsis and septic shock, the current researches on diagnosis and therapy, and proposed that we should not only pay attention to pathogenesis and treatment, but also to sepsis prevention in sepsis researches, and we should try to find out the breakthrough in the interaction and dynamic balance between human being and pathogenic factors. Researches on the strategies to revert strong toxicity of infectious agents to non-toxic or weak pathogenic factors, and to conduct further research concerning biological characteristics of microorganisms and mechanism of drug resistance in order to render them to lose the drug resistance ability, or to increase its sensitivity to the drugs. The above suggested approaches might form the future strategies for preventing and controlling sepsis.

    Sepsis represents the progressive underlying inflammatory pathway secondary to any infectious illness, and ultimately is responsible for most infectious disease-related deaths. Addressing issues related to sepsis has been recognized as an important step towards reducing morbidity and mortality in developing countries, where the majority of the 7.5 million annual deaths in children under 5 years of age are considered to be secondary to sepsis. However, despite its prevalence, sepsis is largely neglected. Application of sepsis definitions created for use in resource-rich countries are neither practical nor feasible in most developing country settings, and alternative definitions designed for use in these settings need to be established. It has also been recognized that the inflammatory state created by sepsis increases the risk of post-discharge morbidity and mortality in developed countries, but exploration of this issue in developing countries is lacking. Research is urgently required to characterize better this potentially important issue.

    Full Text Available Objective  To investigate the prevalence and risk factors of post-traumatic sepsis, and to evaluate the rationality of the 1992, 2001 and 2012 international sepsis definitions in diagnosing post-traumatic sepsis in a trauma intensive care unit (ICU in China. Methods  A one-day cross-sectional survey of trauma patients who met the inclusion criteria was conducted from 8:00 a.m., June 16, 2014 to 8:00 a.m., June 17, 2014 in the trauma ICU of Daping Hospital. The survey data included demographic information, clinical characteristics, pertinent scores (APACHE Ⅱ, SOFA, GCS, ISS and injury mechanism. According to the definition of sepsis as depicted in the 1992, 2001, and 2012 "International Guideline of Sepsis", the patients were divided into A, B and C groups. The infection site, infection pathogens, and key medical treatment were recorded, the infection identified, and the 28day mortality recorded. A positive pathogen culture of respiratory and urinary tracts, blood, cerebrospinal fluid, and wound secretion was adopted as the diagnostic "gold standard" for septic infection. The diagnostic sensitivity and specificity of the three versions of the guidelines were statistically analyzed and the diagnostic feasibility of each definition was assessed. Results  A total of 30 trauma patients were enrolled, twenty-three patients met the 1992 sepsis criteria, 22 met the 2001 criteria, and 20 met the 2012 criteria. The prevalence rates were 76.7%, 73.3%, and 66.7%, respectively, and there was no significant statistical difference. Four patients died within 28 days, which was in line with the diagnostic criteria of the three versions of the sepsis criteria. The 28-day mortality in the three sepsis guidelines groups was 17.4%, 18.2%, and 25.0%, respectively, indicating no statistical difference. By adopting culture-positive pathogens as the "gold standard" of septic infection, the diagnostic sensitivity and specificity of the group A was 77.8% and 25

    RESUMEN El objetivo de este estudio fue analizar el uso de la punción lumbar (PL) en las sospechas de sepsis neonatal tardía. Se recomienda realizar una PL en la evaluación de toda sospecha de sepsis neonatal tardía. Se utilizó una cohorte de 414 neonatos con peso al nacer <2000g en tres hospitales de Lima. Se realizó la PL en 45/214 (21,0%) sospechas de sepsis y en 13/48 (27,1%) sepsis confirmadas por hemocultivo. Se diagnosticó meningitis en 8/214 (3,7%) sospechas y en 8/45 (17,5%) episodios en los que se realizó la PL. El tiempo de tratamiento de los episodios sin PL fue similar a los episodios de sepsis con meningitis descartada y menor a los episodios de meningitis. El uso de la PL es bajo, lo que puede resultar en meningitis no diagnosticadas y tratadas inadecuadamente. Es necesario reforzar la importancia de la PL en la evaluación de sepsis neonatal.

    We aimed to assess the knowledge, attitudes, and perceptions of resident physicians regarding sepsis in general and the Surviving Sepsis Campaign Guidelines in particular. After institutional review board approval, we surveyed internal medicine (IM) and emergency medicine (EM) house staff from 3 separate institutions. House staff were notified of the survey via e-mail from their residency director or chief resident. The survey was Internet-based (using http://www.surveymonkey.com ), voluntary, and anonymous. The Surviving Sepsis Campaign Guidelines were used to develop the survey. The survey was open between December 2015 and April 2016. No incentives for participation were given. Reminder e-mails were sent approximately every 3 to 4 weeks to all eligible participants. Comparisons of responses were evaluated using the N-1 2-proportion test. A total of 133 responses were received. These included 84 from IM house staff, 27 from EM house staff, and 22 who selected "other." Eighty (101/126) percent reported managing at least 1 patient with sepsis in the preceding 30 days, 85% (97/114) rated their knowledge of the Surviving Sepsis Guidelines as "very familiar" or at least "somewhat familiar," and 84% (91/108) believed their training in the diagnosis and management of sepsis was "excellent" or at least "good." However, 43% (47/108) reported not receiving any feedback on their treatment of patients with sepsis in the last 30 days, while 24% (26/108) received feedback once. Both IM and EM house staff received comparable rates of feedback (62% vs 48%, respectively; P = .21). For the 3 questions that directly tested knowledge of the guidelines, the scores of the IM and EM house staff were similar. Notably, house staff on the Surviving Sepsis Campaign Guidelines is warranted, along with more consistent feedback regarding their diagnosis and management of sepsis.

    Full Text Available Emphysematous cystitis (EC is a rare, rapidly progressive infection characterized by gas formation within the bladder wall. Gas production is mainly due to fermentation of glucose or albumin by the pathogenic organisms. We present the case of a patient with EC who presented with severe sepsis of unknown origin. He was also found to have two vesical calculi and a horseshoe kidney. EC was diagnosed on ultrasonography which showed circumferential, acoustic shadowing around the bladder wall. Computed tomography (CT confirmed the diagnosis. Rapid healing could be achieved with appropriate antibiotics and bladder drainage. Endoscopic disintegration of the stones was performed three weeks later, and follow-up was uneventful.

    2012-08-01

    Full Text Available OBJECTIVE: Sepsis is a common condition encountered in hospital environments. There is no effective treatment for sepsis, and it remains an important cause of death at intensive care units. This study aimed to discuss some methods that are available in clinics, and tests that have been recently developed for the diagnosis of sepsis. METHODS: A systematic review was performed through the analysis of the following descriptors: sepsis, diagnostic methods, biological markers, and cytokines. RESULTS: The deleterious effects of sepsis are caused by an imbalance between the invasiveness of the pathogen and the ability of the host to mount an effective immune response. Consequently, the host's immune surveillance fails to eliminate the pathogen, allowing it to spread. Moreover, there is a pro-inflammatory mediator release, inappropriate activation of the coagulation and complement cascades, leading to dysfunction of multiple organs and systems. The difficulty achieve total recovery of the patient is explainable. There is an increased incidence of sepsis worldwide due to factors such as aging population, larger number of surgeries, and number of microorganisms resistant to existing antibiotics. CONCLUSION: The search for new diagnostic markers associated with increased risk of sepsis development and molecules that can be correlated to certain steps of sepsis is becoming necessary. This would allow for earlier diagnosis, facilitate patient prognosis characterization, and prediction of possible evolution of each case. All other markers are regrettably constrained to research units.

    The incidence and mortality of sepsis and severe sepsis in hospitalised patients is seasonal and consistently highest during the winter. The primary aim of this study was to measure the seasonal variation in the prevalence of emergency department (ED) patients with sepsis. This cross-sectional study was performed over two four-week periods in the summer and in the winter, respectively. The clinical records of all patients presenting to the ED during the study periods were retrospectively screened to determine if they met the criteria for “uncomplicated” sepsis and severe sepsis or septic shock. The prevalence of “uncomplicated” sepsis was higher in the winter (43.9 per 1000) compared to the summer (30.7 per 1000). The prevalence of severe sepsis or septic shock was also higher in the winter (17.7 per 1000) compared to the summer (11.7 per 1000). This quantitatively demonstrates the increased ED burden of sepsis in the winter that can be used to inform healthcare planning and resource allocation.

    Test whether inadequate exercise is related to sepsis mortality. Mortality surveillance of an epidemiological cohort of 155,484 National Walkers' and Runners' Health Study participants residing in the United States. Deaths were monitored for an average of 11.6-years using the National Death index through December 31, 2008. Cox proportional hazard analyses were used to compare sepsis mortality (ICD-10 A40-41) to inadequate exercise (<1.07 METh/d run or walked) as measured on their baseline questionnaires. Deaths occurring within one year of the baseline survey were excluded. Sepsis was the underlying cause in 54 deaths (sepsis(underlying)) and a contributing cause in 184 deaths (sepsis(contributing)), or 238 total sepsis-related deaths (sepsis(total)). Inadequate exercise was associated with 2.24-fold increased risk for sepsis(underlying) (95%CI: 1.21 to 4.07-fold, P = 0.01), 2.11-fold increased risk for sepsis(contributing) (95%CI: 1.51- to 2.92-fold, P<10(-4)), and 2.13-fold increased risk for sepsis(total) (95%CI: 1.59- to 2.84-fold, P<10(-6)) when adjusted for age, sex, race, and cohort. The risk increase did not differ significantly between runners and walkers, by sex, or by age. Sepsis(total) risk was greater in diabetics (P = 10(-5)), cancer survivors (P = 0.0001), and heart attack survivors (P = 0.003) and increased with waist circumference (P = 0.0004). The sepsis(total) risk associated with inadequate exercise persisted when further adjusted for diabetes, prior cancer, prior heart attack and waist circumference, and when excluding deaths with cancer, or cardiovascular, respiratory, or genitourinary disease as the underlying cause. Inadequate exercise also increased sepsis(total) risk in 2163 baseline diabetics (4.78-fold, 95%CI: 2.1- to 13.8-fold, P = 0.0001) when adjusted, which was significantly greater (P = 0.03) than the adjusted risk increase in non-diabetics (1.80-fold, 95%CI: 1.30- to 2.46-fold, P = 0

    Hotchkiss, Richard S.; Monneret, Guillaume; Payen, Didier

    2014-01-01

    Sepsis — severe life-threatening infection with organ dysfunction — initiates a complex interplay of host pro- and anti-inflammatory processes. In a real sense, sepsis can be considered a race to the death between the pathogens and the host immune system. It is the proper balance between the often competing pro- and anti-inflammatory pathways that determines the fate of the individual. Although the field of sepsis research has witnessed the failure of many highly-touted clinical trials, a better understanding of the pathophysiological basis of the disorder and the mechanisms responsible for the associated pro- and anti-inflammatory responses is leading to a novel approach to treat this highly lethal condition. Biomarker-guided immunotherapy administered to patients at the proper immune phase of sepsis represents a potential major advance in the treatment of sepsis and more broadly in the field of infectious disease.

    Rapid and accurate diagnosis of neonatal sepsis is highly warranted because of high associated morbidity and mortality. The aim of this study was to evaluate the performance of a novel multiplex PCR assay for diagnosis of late-onset sepsis and to investigate the value of bacterial DNA load (BDL) determination as a measure of infection severity. This cross-sectional study was conducted in a neonatal intensive care unit. Preterm and/or very low birth weight infants suspected for late-onset sepsis were included. Upon suspicion of sepsis, a whole blood sample was drawn for multiplex PCR to detect the eight most common bacteria causing neonatal sepsis, as well as for blood culture. BDL was determined in episodes with a positive multiplex PCR. In total, 91 episodes of suspected sepsis were investigated, and PCR was positive in 53 (58%) and blood culture in 60 (66%) episodes, yielding no significant difference in detection rate (p = 0.17). Multiplex PCR showed a sensitivity of 77%, specificity of 81%, positive predictive value of 87%, and negative predictive value of 68% compared with blood culture. Episodes with discordant results of PCR and blood culture included mainly detection of coagulase-negative staphylococci (CoNS). C-reactive protein (CRP) level and immature to total neutrophil (I/T) ratio were lower in these episodes, indicating less severe disease or even contamination. Median BDL was high (4.1 log 10 cfu Eq/ml) with a wide range, and was it higher in episodes with a positive blood culture than in those with a negative blood culture (4.5 versus 2.5 log 10 cfu Eq/ml; p PCR provides a powerful assay to enhance rapid identification of the causative pathogen in late-onset sepsis. BDL measurement may be a useful indicator of severity of infection.

    2018-01-01

    Sepsis, the life-threatening organ dysfunction caused by a dysregulated host response to infection, is difficult to identify and to prognosticate for. In people with sepsis, procalcitonin (PCT) measurement aids diagnosis, enables therapeutic monitoring and improves prognostic accuracy. This study used a commercial canine PCT assay to measure plasma PCT concentrations in dogs with gastric dilatation volvulus (GDV) syndrome and in dogs with sepsis. It was hypothesised that dogs with GDV syndrome and with sepsis have greater plasma PCT concentrations than healthy dogs and that dogs with sepsis have greater PCT concentrations than dogs with GDV syndrome. Before analysing canine plasma samples, the ability of the assay to identify canine PCT, in addition to assay imprecision and the lower limit of detection were established. The assay had low imprecision with coefficients of variation ≤4.5 per cent. The lower limit of detection was 3.4 pg/ml. Plasma PCT concentrations were measured in 20 dogs with sepsis, in 32 dogs with GDV syndrome and in 52 healthy dogs. Median (IQR) PCT concentration in dogs with sepsis 78.7 pg/ml (39.1–164.7) was significantly greater than in healthy dogs 49.8 pg/ml (36.2–63.7) (P=0.019), but there were no significant differences between PCT concentrations in dogs with GDV syndrome and controls (P=0.072) or between dogs with sepsis and GDV syndrome (P=1.000). Dogs with sepsis have significantly increased plasma PCT concentrations compared with healthy dogs, although considerable overlap between these populations was identified. Future investigations should confirm this finding in other populations and evaluate the diagnostic and prognostic value of PCT in dogs with sepsis. PMID:29682292

    Prompt recognition and aggressive early treatment are the only effective measures against invasive meningococcal disease (IMD). Anti-inflammatory adjunctive treatment remains controversial and difficult to assess in patients with IMD. The purpose of this study was to evaluate the effect of dexamethasone (DXM) as adjunctive treatment in different clinical forms of IMD, and attempt to answer if DXM should be routinely used in the treatment of IMD. In this non-interventional clinical study (NIS), 39 patients with meningococcal septicaemia with or without of meningitis were included, and compared regarding the impact of dexamethasone (DXM), as an adjunctive treatment, on the outcome of IMD. SPSS statistics is used for statistical processing of data. Thirty (76.9%) patients with IMD had sepsis and meningitis, and 9 (23.1%) of them had sepsis alone. Dexamethasone was used in 24 (61.5%) cases, in both clinical groups. The overall mortality rate was 10.3%. Pneumonia was diagnosed in 6 patients (15.4%), arthritis in 3 of them (7.7%), and subdural effusion in one patient (2.6%). The data showed a significant statistical difference on the length of hospitalization, and WBC normalization in groups of patients treated with DXM. The use of DXM as adjunctive therapy in invasive meningococcal disease has a degree of proven benefits and no harmful effects. In fighting this very dangerous and complex infection, even a limited benefit is sufficient to recommend the use of DXM as adjunctive treatment in invasive meningococcal disease.

    Cytomegalovirus (CMV) reactivation in non-immune-suppressed critically ill patients is an area of increasing interest. CMV has long been appreciated as a pathogen in immunocompromised hosts. CMV reactivates in approximately one-third of latently infected non-immune-suppressed hosts during critical illness; however, its role as a pathogen in these patients remains unclear. CMV reactivation has been linked to bacterial sepsis and likely results from inflammation, transient immune compromise, and viral epigenetic changes. While CMV may improve immune response to some bacterial infections, other data suggest that CMV induces exaggerated responses to severe infections that may be harmful to latently infected hosts. These results also suggest that previous infection history may explain significant differences seen between human septic responses and murine models of sepsis. While critically ill human hosts clearly have worse outcomes associated with CMV reactivation, determining causality remains an area of investigation, with randomized control trials currently being performed. Here we review the current literature and highlight areas for future investigation.

    The Surviving Sepsis Campaign guidelines are designed to decrease mortality through consistent application of a 7-element bundle. This study evaluated the impact of improvement in bundle adherence using a time-series analysis of compliance with the bundle elements before and after interventions intended to improve the process, while also looking at hospital mortality. This article describes interventions used to improve bundle compliance and hospital mortality in patients admitted through the emergency department with sepsis, severe sepsis, or septic shock. Quality improvement methodology was used to develop high-impact interventions that led to dramatically improved adherence to the Surviving Sepsis Campaign guidelines bundle. Improved performance was associated with a significant decrease in the in-hospital mortality of severe sepsis patients presenting to the emergency department.

    The study aimed to construct and manage an acute respiratory distress syndrome (ARDS)/sepsis registry that can be used for data warehousing and clinical research. The workflow methodology and software solution of research electronic data capture (REDCap) was used to construct the ARDS/sepsis registry. Clinical data from ARDS and sepsis patients registered to the intensive care unit (ICU) of our hospital formed the registry. These data were converted to the electronic case report form (eCRF) format used in REDCap by trained medical staff. Data validation, quality control, and database management were conducted to ensure data integrity. The clinical data of 67 patients registered to the ICU between June 2013 and December 2013 were analyzed. Of the 67 patients, 45 (67.2%) were classified as sepsis, 14 (20.9%) as ARDS, and eight (11.9%) as sepsis-associated ARDS. The patients' information, comprising demographic characteristics, medical history, clinical interventions, daily assessment, clinical outcome, and follow-up data, was properly managed and safely stored in the ARDS/sepsis registry. Data efficiency was guaranteed by performing data collection and data entry twice weekly and every two weeks, respectively. The ARDS/sepsis database that we constructed and manage with REDCap in the ICU can provide a solid foundation for translational research on the clinical data of interest, and a model for development of other medical registries in the future.

    Sepsis is a leading killer of children worldwide with numerous differentially expressed genes reported to be associated with sepsis. Identifying core pathways in an individual is important for understanding septic mechanisms and for the future application of custom therapeutic decisions. Samples used in the study were from a control group (n=18) and pediatric sepsis group (n=52). Based on Kauffman's attractor theory, differentially expressed pathways associated with pediatric sepsis were detected as attractors. When the distribution results of attractors are consistent with the distribution of total data assessed using support vector machine, the individualized pathway aberrance score (iPAS) was calculated to distinguish differences. Through attractor and Kyoto Encyclopedia of Genes and Genomes functional analysis, 277 enriched pathways were identified as attractors. There were 81 pathways with Ppathways with Ppathway clusters and four sample clusters. Thus, in the majority pediatric sepsis samples, core pathways can be detected as different from accumulated normal samples. In conclusion, a novel procedure that identified the dysregulated attractors in individuals with pediatric sepsis was constructed. Attractors can be markers to identify pathways involved in pediatric sepsis. iPAS may provide a correlation score for each of the signaling pathways present in an individual patient. This process may improve the personalized interpretation of disease mechanisms and may be useful in the forthcoming era of personalized medicine.

    Full Text Available Sepsis remains a major cause of morbidity and mortality in surgical patients and trauma victims, mainly due to sepsis-induced multiple organ dysfunction. In contrast to preclinical studies, most clinical trials of promising new treatment strategies for sepsis have fails to demonstrate efficacy. Although many reasons could account for this discrepancy, the misinterpretation of preclinical data obtained from experimental studies, and especially the use of animal models that do not adequately mimic human sepsis may have been contributing factors. In this review, the benefits and limitations of various animal models of sepsis are discussed to clarify the extend to which findings are relevant to human sepsis, particularly with respect to the subsequent design and execution of clinical trials. Such models include intravascular infusion of endotoxin or live bacteria, bacterial peritonitis, cecal ligation and perforation, soft tissue infection, pneumonia or meningitis models, using different animal species including rats, mice, rabbits, dogs, pigs, sheep and nonhuman primates. Despite several limitations, animal models remain essential in the development of all new therapies for sepsis and septic shock, because they provide fundamental information about the pharmacokinetics, toxicity, and mechanism of drug action that cannot be duplicated by other methods. New therapeutic agents should be studies in infection models, even after the initiation of the septic process. Furthermore, debility conditions need to be reproduced to avoid the exclusive use of healthy animals, which often do not represent the human septic patient.

    Full Text Available In elderly population sepsis is one of the leading causes of intensive care unit (ICU admissions in the United States. Sepsis-induced delirium (SID is the most frequent cause of delirium in ICU (1. Together delirium and SID represent under recognized public health problems which place an increasing financial burden on the US health care system, currently estimated at 143 to 152 billion dollars per year (2. The interest in SID was recently reignited as it was demonstrated that, contrary to prior beliefs, cognitive deficits induced by this condition may be irreversible and lead to dementia (3-4. Conversely, it is construed that diagnosing SID early or mitigating its full blown manifestations may preempt geriatric cognitive disorders. Biological markers specific for sepsis and SID would facilitate the development of potential therapies, monitor the disease process and at the same time enable elderly individuals to make better informed decisions regarding surgeries which may pose the risk of complications, including sepsis and delirium.This article proposes a battery of peripheral blood markers to be used for diagnostic and prognostic purposes in sepsis and SID. Though each individual marker may not be specific enough, we believe that together as a battery they may achieve the necessary accuracy to answer two important questions: who may be vulnerable to the development of sepsis, and who may develop SID and irreversible cognitive deficits following sepsis?

    To determine the frequency of early onset neonatal sepsis in newborn with various duration of preterm premature rupture of membranes (PPROM). Study Design: Cross sectional study. Place and Duration of Study: Neonatal Intensive Care Unit Combined Military Hospital, Lahore from November 2009 to November 2010. Material and Methods: Neonates of singleton pregnancies complicated by preterm premature rupture of the membranes (PPROM) with delivery between 30 and 36 weeks gestation were included in the study. The overall frequency of neonatal sepsis was calculated on clinical and serological basis. Comparison of the frequency of sepsis among groups with varying duration of rupture of membranes was done. Results: Out of 164 babies, 84 (51.2%) were female and 80 (48.8%) were male. Mean maternal age was 23 years (range: 18-36 years). Mean gestational age was 33 weeks (range: 30-36 weeks). Sepsis was suspected in 41(25%) babies on clinical grounds. C-reactive protein was raised in 36 (22%) neonates. There was statistically insignificant difference between clinical versus serological diagnosis (p=0.515). Frequency of neonatal sepsis was significantly higher in mothers with longer duration of rupture of membrane (p < 0.001). Conclusion: Frequency of neonatal sepsis was observed to be 22%. PPROM is an important risk factor for early onset neonatal sepsis. (author)

  10. Neonatal sepsis: Highlighting the principles of diagnosis and management

    Full Text Available Neonatal sepsis is a clinical syndrome consisting of nonspecific symptoms and signs of infection, accompanied by a bacteraemia in the first 28 days of life. The risk of neonatal sepsis and death increases with decreasing birth weight and gestational age. South African data have reported the overall incidence of neonatal sepsis to be 8.5 - 10%, with late-onset sepsis accounting for most of these infections. The diagnosis of neonatal sepsis is not always straightforward, and the initiation and continuation of antimicrobials in these situations relies on good clinical judgment. The need for empirical antimicrobials is driven by the existence of risk factors for early-onset sepsis and clinical symptoms and signs of late-onset sepsis. Antimicrobial stewardship programmes should be in place to guide clinicians to either stop, change, or continue antimicrobials. Institution-specific knowledge of the most common pathogens and the antimicrobial susceptibility pattern is important to prevent the emergence of further antimicrobial resistance.

  11. Importance of measuring lactate levels in children with sepsis.

    Sepsis is a major public health problem as well as one of the leading causes of preventable death in children because of failure to recognise the early signs and symptoms and to resuscitate rapidly. Blood lactate levels are used to assess the severity of sepsis and the effectiveness of resuscitation. Lactate levels are easily obtainable and should be checked in all patients admitted with suspected sepsis within six hours of presentation. The test should be repeated four and eight-hours post-diagnosis of sepsis. For the diagnosis of sepsis, patients' clinical symptoms, along with the combined analysis of partial pressure of oxygen, carbon dioxide and lactate levels, should be used. A multitude of factors can cause elevated lactate levels and so clinicians should use elevated levels cautiously by considering all other aetiologies. This article, which focuses on practice in Australia but makes reference to the UK, discusses the importance of measuring lactate levels in sepsis, the pathophysiology of lactate production, causes of elevated lactate levels, lactate measurement, nursing management of patients with elevated lactate levels, limitations of using lactate as a biomarker for diagnosing sepsis and implications for practice. ©2012 RCN Publishing Company Ltd.

    Systemic inflammatory response syndrome (SIRS) and sepsis can be challenging to diagnose in cats. Retrospectively, we investigated the diagnostic and prognostic potential of serum amyloid A (SAA), a major feline acute-phase protein (APP), in a population of critically ill cats with SIRS related to trauma or sepsis. A total of 56 SIRS cats (trauma n = 27; sepsis n = 29) were included and compared with healthy controls ( n = 18). SAA concentration was significantly increased in SIRS cats compared to controls, confirming its potential for the detection of systemic inflammation in this species. Significantly higher values of SAA were detected in cats belonging to the sepsis group; however, according to the results of the receiver operating characteristic curve analysis, the value of using SAA (>81 mg/L) to discriminate septic cats was only moderate (AUC = 0.76). Additionally, cats with sepsis had significantly higher serum bilirubin concentrations and toxic neutrophil changes compared to the trauma group. Overall, 38 of 56 cats were survivors; 18 of 56 were non-survivors, with 83% of the non-survivors (15 of 18) belonging to the sepsis group. Serum bilirubin concentration, but not SAA, was able to predict outcome. Prospective studies are needed to assess the potential of SAA in the diagnosis of feline sepsis and outcome prediction.

    Full Text Available Context: There is a logical connection with biomarkers, trauma, and sepsis. This review paper provides new information and clinical practice implications. Biomarkers are very important especially in pediatrics. Procalcitonin and other biomarkers are helpful in identifying neonatal sepsis, defense mechanisms of the immune system. Pediatric trauma and sepsis is very important both in infants and in children. Stress management both in trauma is based upon the notion that stress causes an immune imbalance in susceptible individuals. Evidence Acquisition: Data sources included studies indexed in PubMed, a meta- analysis, predictive values, research strategies, and quality assessments. A recent paper by one of the authors stated marked increase in serum procalcitonin during the course of a septic process often indicates an exacerbation of the illness, and a decreasing level is a sign of improvement. A review of epidemiologic studies on pediatric soccer patients was also addressed. Keywords for searching included biomarkers, immunity, trauma, and sepsis. Results: Of 50 reviewed articles, 34 eligible articles were selected including biomarkers, predictive values for procalcitonin, identifying children at risk for intra-abdominal injuries, blunt trauma, and epidemiology, a meta-analysis. Of neonatal associated sepsis, the NF-kappa B pathway by inflammatory stimuli in human neutrophils, predictive value of gelsolin for the outcomes of preterm neonates, a meta-analysis interleukin-8 for neonatal sepsis diagnosis. Conclusions: Biomarkers are very important especially in pediatrics. Procalcitonin and other biomarkers are helpful in identifying neonatal sepsis, defense mechanisms, and physiological functions of the immune system. Pediatric trauma and sepsis is very important both in infants and in children. Various topics were covered such as biomarkers, trauma, sepsis, inflammation, innate immunity, role of neutrophils and IL-8, reactive oxygen species

    To ascertain and compare microbial growth pattern in blood culture of septic neonates who were either totally breast or formula fed. Study Design: Cross sectional study. Place and Duration of Study: The Children's Hospital Lahore, Pakistan from Feb 2012 to Dec 2012. Methodology: All clinically septic neonates, who were either exclusively breast fed or formula fed, were enrolled in the study. They were divided into two groups and studied for the type of organisms grown on blood culture. Group-A were breast fed and group-B were formula fed. Neonates who were blood culture negative or had growth of multiple organisms or had incomplete data or who died / left against medical advice before completing the required data or babies receiving milk feeding from multiple sources or no feeding at all were excluded. BACTEC technique was used for obtaining bacterial growth. SPSS version 19 was used for statistical analysis. Results: A total of 380 clinically septic neonates were enrolled. Each group consisted of 190 subjects. Incidence of culture positive sepsis in breast fed and in formula fed was 6.7% and 15.7% respectively (p-value = 0.0001). Overall, gram-negative organisms constituted the majority (16.1%). Thirty seven percent cultures grew coagulase negative Staphylococcus (CoNS) followed by Klebsiella spp (23.4%). In group A, gram-negative and gram-positive organisms were equally distributed whilst in group-B, gram-negative organisms were three times more frequent than gram-positive organisms. Predominant pattern of organisms was also different in the two groups. In group-A, CoNS was predominant while in group-B, Klebsiella spp. was most frequent. Conclusion: Culture positive sepsis is more than two times greater in formula fed babies and is caused predominantly by gram-negative organisms whilst in breast fed babies, CoNS is the commonest organism.

    2015-01-01

    Conclusion: There is insufficient evidence to justify the routine use of β-blockers in sepsis. A large adequately powered multi-centered randomized controlled clinical trial is required to address the question on the efficacy of β-blocker usage in sepsis. This trial should also consider a number of important questions including the choice of β-blocker used, optimal dosing, timing of intervention, duration of intervention and discontinuation of the drug. Until such time based on the available evidence, there is no place for the use of β-blockers in sepsis in current clinical practice.

  16. Implications of the new sepsis definition on research and practice.

    2017-04-01

    The Society of Critical-Care Medicine and the European Society of Intensive Care Medicine recently announced a marked change in the sepsis definition. A task force of 19 sepsis clinicians and researchers made the change based on advances in the pathobiological understanding of the septic process. The task force determined that there were numerous justifications for a revision of the sepsis definition, which are outlined in this article. The systemic inflammatory response criteria have been replaced by the Sequential Organ Failure Assessment (SOFA) score in the newly operationalized definition (Singer et al., 2016). In addition to the definition change, the task force recommended using the new quick SOFA (qSOFA) score in non-ICU settings, as a risk stratification tool to identify patients who may be septic or be at risk of developing sepsis. The change in definition will likely have a negative impact on sepsis research in the short-term as hospitals adjust their coding for the new definition, but may result in less misclassification bias and improved research data in the long-term. While the intent of the SCCM/ESICM task force was to better define sepsis for coding and epidemiological research purposes, there is the potential for improved patient outcomes if clinicians are better able to differentiate between sepsis and inflammatory events. The qSOFA tool may also aid clinicians in recognizing sepsis in a quicker manner, leading to more timely treatment, and potentially better outcomes. While the new operationalized Sepsis-3 definition appears on the surface to be an improvement over the previous iterations, it remains to be seen if research data will be more robust using the new criteria. There is the potential for better patient outcomes if clinicians are better able to differentiate sepsis from inflammatory events with the new definition, and if sepsis cases are recognized sooner with qSOFA. Future research on the impact of this definition change on research and

    We report seven patients in whom five dropped surgical clips and two gallstones were visualized in the peritoneal cavity, on radiological studies. In two, subphrenic abscesses and empyemas developed as a result of dropped clips into the peritoneal cavity during or following laparoscopic cholecystectomy. In one of these two, a clip was removed surgically from the site of an abscess. In two other patients dropped gallstones, and in three, dropped clips led to no complications. These were seen incidentally on studies done for other indications. Abdominal abscess secondary to dropped gallstones is a well-recognized complication of laparoscopic cholecystectomy (LC). We conclude that even though dropped surgical clips usually do not cause problems, they should be considered as a risk additional to other well-known causes of post-LC abdominal sepsis

    Neonatal infections are a major cause of death worldwide. Simple procedures for identifying infants with infection that need referral for treatment are therefore of major public health importance. We investigated 3303 infants Ethiopia, The Gambia, Papua New Guinea and The Philippines, using a standardized approach. Historical factors and clinical signs predicting sepsis, meningitis, hypoxemia, deaths and an ordinal scale indicating severe disease were investigated by logistic regression, and the performance of simple combination rules was explored. In multivariable analysis, reduced feeding ability, no spontaneous movement, temperature >38 degrees C, being drowsy/unconscious, a history of a feeding problem, history of change in activity, being agitated, the presence of lower chest wall indrawing, respiratory rate >60 breaths/min, grunting, cyanosis, a history of convulsions, a bulging fontanel and slow digital capillary refill were independent predictors of severe disease. The presence of any 1 of these 14 signs had a sensitivity for severe disease (defined as sepsis, meningitis, hypoxemia, or radiologically proven pneumonia) of 87% and a specificity of 54%. More stringent combinations, such as demanding 2 signs from the list, resulted in a considerable loss of sensitivity. By contrast only slight loss of sensitivity and considerable gain of specificity resulted from reducing the list to 9 signs. Requiring the presence of fever and any other sign produced a diagnostic rule with extremely low sensitivity (25%). Physical signs can be used to identify young infants at risk of severe disease, however with limited specificity, resulting in large numbers of unnecessary referrals. Further studies are required to validate and refine the prediction of severe disease, especially in the first week of life, but there appear to be limits on the accuracy of prediction that is achievable.

    Purpose: Prompt recognition and aggressive early treatment are the only effective measures against invasive meningococcal disease (IMD). Anti-inflammatory adjunctive treatment remains controversial and difficult to assess in patients with IMD. The purpose of this study was to evaluate the effect of dexamethasone (DXM) as adjunctive treatment in different clinical forms of IMD, and attempt to answer if DXM should be routinely used in the treatment of IMD. Methods: In this non-interventional clinical study (NIS), 39 patients with meningococcal septicaemia with or without of meningitis were included, and compared regarding the impact of dexamethasone (DXM), as an adjunctive treatment, on the outcome of IMD. SPSS statistics is used for statistical processing of data. Results: Thirty (76.9%) patients with IMD had sepsis and meningitis, and 9 (23.1%) of them had sepsis alone. Dexamethasone was used in 24 (61.5%) cases, in both clinical groups. The overall mortality rate was 10.3%. Pneumonia was diagnosed in 6 patients (15.4%), arthritis in 3 of them (7.7%), and subdural effusion in one patient (2.6%). The data showed a significant statistical difference on the length of hospitalization, and WBC normalization in groups of patients treated with DXM. Conclusion: The use of DXM as adjunctive therapy in invasive meningococcal disease has a degree of proven benefits and no harmful effects. In fighting this very dangerous and complex infection, even a limited benefit is sufficient to recommend the use of DXM as adjunctive treatment in invasive meningococcal disease. PMID:28974828

    This study evaluated the accuracy and utility of the In-111 labeled WBC imaging in a series of patients who were suspected of having musculoskeletal sepsis. The labeling of the WBCs was patterned after a method previously described, in which the WBCs are labeled with In-111 oxine in plasma. The WBCs from 100 ml of blood are separated and incubated with In-111 oxine complex, and then 500 μCi. of the labeled cells were reinjected into the patient. Images of the areas in question were obtained at 24 hrs. In some instances, 48 hour images were also obtained. Images were interpreted using consistent criteria. Forty imaging procedures were done on 39 patients. These included 39 total joint protheses, and 17 other images to evaluate possible osteomyelitis, septic arthritis or deep abscesses. Of these studies, 15 were positive, and 42 negative. The findings were then correlated with operative culture and pathology in 21, aspiration cultures and gram stains in 14, and with clinical findings in the remaining 21. This correlation showed 41 true negatives, 12 true positives, 1 false negative, and 2 false positives. The sensitivity was 92.9% and the specificity was 95.2%l. The false negative occurred in a patient on chronic suppressive antibiotic therapy for an infected total hip replacement. The false positive images occurred in a patient with active rheumatoid arthritis and in a patient imaged one month post operative placement of the prosthesis. These images were very useful in several septic patients who had many possible sites of infection. The authors conclude that In-III imaging is an accurate and useful non-invasive method of evaluating musculoskeletal sepsis

    To quantify the coinciding improvement in the clinical diagnosis of sepsis, its documentation in the electronic health records, and subsequent medical coding of sepsis for billing purposes in recent years. We examined 98,267 hospitalizations in 66,208 patients who met systemic inflammatory response syndrome criteria at a tertiary care center from 2008 to 2012. We used g-computation to estimate the causal effect of the year of hospitalization on receiving an International Classification of Diseases, Ninth Revision, Clinical Modification discharge diagnosis code for sepsis by estimating changes in the probability of getting diagnosed and coded for sepsis during the study period. When adjusted for demographics, Charlson-Deyo comorbidity index, blood culture frequency per hospitalization, and intensive care unit admission, the causal risk difference for receiving a discharge code for sepsis per 100 hospitalizations with systemic inflammatory response syndrome, had the hospitalization occurred in 2012, was estimated to be 3.9% (95% confidence interval [CI], 3.8%-4.0%), 3.4% (95% CI, 3.3%-3.5%), 2.2% (95% CI, 2.1%-2.3%), and 0.9% (95% CI, 0.8%-1.1%) from 2008 to 2011, respectively. Patients with similar characteristics and risk factors had a higher of probability of getting diagnosed, documented, and coded for sepsis in 2012 than in previous years, which contributed to an apparent increase in sepsis incidence.

    Pentraxin-3 (PTX-3) is an acute-phase protein involved in inflammatory and infectious processes. This study assesses its diagnostic and prognostic value in patients with sepsis or septic shock in a medical intensive care unit (ICU). The study includes 213 ICU patients with clinical criteria of sepsis and septic shock. 77 donors served as controls. Plasma levels of PTX-3, procalcitonin (PCT) and interleukin-6 were measured on day 1, 3 and 8. PTX-3 correlated with higher lactate levels as well as with APACHE II and SOFA scores (p = 0.0001). PTX-3 levels of patients with sepsis or septic shock were consistently significantly higher than in the control group (p ≤ 0.001). Plasma levels were able to discriminate sepsis and septic shock significantly on day 1, 3 and 8 (range of AUC 0.73-0.92, p = 0.0001). Uniform cut-off levels were defined at ≥5 ng/ml for at least sepsis, ≥9 ng/ml for septic shock (p = 0.0001). PTX-3 reveals diagnostic value for sepsis and septic shock during the first week of intensive care treatment, comparable to interleukin-6 according to latest Sepsis-3 definitions. NCT01535534 .

    Purpose: To evaluate the diagnostic relevance of CT in patients with sepsis of unknown origin. Material and Methods: Sixty-three consecutive intensive care patients with suspicion of an abscess and negative or inconclusive previous radiological examinations were included. CT was performed using the helical technique. A total of 45 abdominal and 38 chest examinations were evaluated. Results: 5/38 examinations of the chest revealed the source of sepsis (pleural empyema 2, lung abscess 1, mediastinitis 1, retrosternal abscess 1). 7/45 abdominal CT examinations showed the source of sepsis (intraabdominal abscess 2, hepatic abscess 3, intestinal perforation 1, gangrenous colitis 1). Conclusion: CT is useful for the evaluation of patients with fever or sepsis without a known source. Due to the detection of a spetic focus by CT, 19% of the patients in our study could be immediately referred to causal therapy as percutaneous drainage or surgery. (orig.)

    Sepsis, with its often devastating consequences for patients and their families, remains a major public health concern that poses an increasing financial burden. Early resuscitation together with the elucidation of the biological pathways and pathophysiological mechanisms with the use of "-omics" technologies have started changing the clinical and research landscape in sepsis. Metabolomics (i.e., the study of the metabolome), an "-omics" technology further down in the "-omics" cascade between the genome and the phenome, could be particularly fruitful in sepsis research with the potential to alter the clinical practice. Apart from its benefit for the individual patient, metabolomics has an impact on public health that extends beyond its applications in medicine. In this review, we present recent developments in metabolomics research in sepsis, with a focus on pneumonia, and we discuss the impact of metabolomics on public health, with a focus on free/libre open source software. © 2018 S.

    Sepsis is a critical clinical syndrome which keep puzzling the medical profession for many years. Recently, the results from several large-scale trials challenged the necessity of early goal directed therapy (EGDT) in surviving sepsis bundle, These trials were not opposed to EGDT but bring new concept that it is essential to utilize therapy with multiple monitoring measures in order to minimize injury while guarantee the safety . Deeper understanding in the pathogenesis of sepsis gives rise to the update of its definition based on vital organ dysfunction. The importance of dynamic monitoring in defining sepsis also need to be emphasized. Developing more effective monitoring measures could provide better treatments, thus improve the prognosis of septic patients.

    2017-11-01

    Systemic Inflammatory Response Syndrome (SIRS) and sepsis remain leading causes of death. Despite many similarities, the two entities are very distinct clinically and immunologically. T-Lymphocytes play a key pivotal role in the pathogenesis and ultimately outcome following both SIRS and sepsis. Integrins are essential in the trafficking and migration of lymphocytes. They also serve vital roles in efficient wound healing and clearance of infections. Here, we investigate whether integrin expression, specifically β1 (CD29) and β2 (CD18), are disrupted in SIRS and sepsis, and assess differences in integrin expression between these two critically ill clinical categories. T-Lymphocytes were isolated from whole blood collected from ICU patients exhibiting SIRS or sepsis. Samples were analyzed for CD18 (β2) and CD29 (β1) on CD3 + T cells through flow cytometry. Septic patients were stratified into either exclusively abdominal or non-abdominal sources of sepsis. CD18 was almost ubiquitously expressed on CD3 + T cells irrespective of clinical condition. However, CD29 (β1 integrin) was lowest in SIRS patients (20.4% of CD3 + T cells) when compared with either septic patients (35.5%) or healthy volunteers (54.1%). Furthermore, there was evidence of compartmentalization in septic patients, where abdominal sources had a greater percentage of CD3 + CD29 + T cells (41.7%) when compared with those with non-abdominal sources (29.5%). Distinct differences in T-cell integrin expression exists between patients in SIRS versus sepsis, as well as relative to the source of sepsis. Further work is needed to understand cause and effect relative to the progression from SIRS into sepsis.

    Identifying modifiable factors for sepsis-associated encephalopathy may help improve patient care and outcomes. We conducted a retrospective analysis of a prospective multicenter database. Sepsis-associated encephalopathy (SAE) was defined by a score on the Glasgow coma scale (GCS) sepsis at ICU admission, of whom 1341 (53%) had sepsis-associated encephalopathy. After adjusting for baseline characteristics, site of infection, and type of admission, the following factors remained independently associated with sepsis-associated encephalopathy: acute renal failure [adjusted odds ratio (aOR) = 1.41, 95% confidence interval (CI) 1.19-1.67], hypoglycemia 10 mmol/l (aOR = 1.37, 95% CI 1.09-1.72), hypercapnia >45 mmHg (aOR = 1.91, 95% CI 1.53-2.38), hypernatremia >145 mmol/l (aOR = 2.30, 95% CI 1.48-3.57), and S. aureus (aOR = 1.54, 95% CI 1.05-2.25). Sepsis-associated encephalopathy was associated with higher mortality, higher use of ICU resources, and longer hospital stay. After adjusting for age, comorbidities, year of admission, and non-neurological SOFA score, even mild alteration of mental status (i.e., a score on the GCS of 13-14) remained independently associated with mortality (adjusted hazard ratio = 1.38, 95% CI 1.09-1.76). Acute renal failure and common metabolic disturbances represent potentially modifiable factors contributing to sepsis-associated encephalopathy. However, a true causal relationship has yet to be demonstrated. Our study confirms the prognostic significance of mild alteration of mental status in patients with sepsis.

  2. Role of C5 Activation Products in Sepsis

    Directory of Open Access Journals (Sweden)

    Peter A. Ward

    2010-01-01

    Full Text Available Complement activation products are known to be generated in the setting of both experimental and human sepsis. C5 activation products (C5a anaphylatoxin and the membrane attack complex [MAC] C5b-9 are generated during sepsis following infusion of endotoxin, or after cecal ligation and puncture (CLP, which produces polymicrobial sepsis. C5a reacts with its receptors C5aR and C5L2 in a manner that creates the “cytokine storm”, and is associated with development of multiorgan failure (MOF. A number of other complications arising from the interaction of C5a with its receptors include apoptosis of lymphoid cells, loss of innate immune functions of neutrophils (PMNs, polymorphonuclear leukocytes, cardiomyopathy, disseminated intravascular coagulation, and complications associated with MOF. Neutralization of C5a in vivo or absence/blockade of C5a receptors greatly reduces the adverse events in the setting of sepsis, markedly attenuates MOF, and greatly improves survival. Regarding the possible role of C5b-9 in sepsis, the literature is conflicting. Some studies suggest that C5b-9 is protective, while other studies suggest the contrary. Clearly, in human sepsis, C5a and its receptors may be logical targets for interception.

    Finely tuned to respond quickly to infections, neutrophils have amazing abilities to migrate fast and efficiently towards sites of infection and inflammation. Although neutrophils ability to migrate is perturbed in patients after major burns, no correlations have yet been demonstrated between altered migration and higher rate of infections and sepsis in these patients when compared to healthy individuals. To probe if such correlations exist, we designed microfluidic devices to quantify the neutrophil migration phenotype with high precision. Inside these devices, moving neutrophils are confined in channels smaller than the neutrophils and forced to make directional decisions at bifurcations and around posts. We employed these devices to quantify neutrophil migration across 18 independent parameters in 74 blood samples from 13 patients with major burns and 3 healthy subjects. Blinded, retrospective analysis of clinical data and neutrophil migration parameters revealed that neutrophils isolated from blood samples collected during sepsis migrate spontaneously inside the microfluidic channels. The spontaneous neutrophil migration is a unique phenotype, typical for patients with major burns during sepsis and often observed one or two days before the diagnosis of sepsis is confirmed. The spontaneous neutrophil migration phenotype is rare in patients with major burns in the absence of sepsis, and is not encountered in healthy individuals. Our findings warrant further studies of neutrophils and their utility for early diagnosing and monitoring sepsis in patients after major burns.

    As immunosuppressive therapy and allograft survival have improved, the increased incidence of sepsis has become a major hurdle of disease-free survival after renal transplantation. We identified 112 of 957 kidney transplant recipients (KTRs) with sepsis. In all, 31 KTRs developed severe sepsis or septic shock, and 30 KTRs died from sepsis. KTRs without sepsis were used for comparison. CMV-specific and alloreactive T cells were measured using an interferon-γ Elispot assay. The extent of immunosuppression was quantified by lymphocyte subpopulations. Five-year patient survival was 70.3% with sepsis compared to 88.2% without (Psepsis (Psepsis (Psepsis was associated with decreased CD3+ and CD4+ T cells pre-transplantation (Psepsis (Psepsis (Psepsis show inferior patient survival and allograft function.

  5. Role of Circulating Lymphocytes in Patients with Sepsis

    2014-01-01

    Full Text Available Sepsis is a systemic inflammatory response syndrome due to infection. The incidence rate is estimated to be up to 19 million cases worldwide per year and the number of cases is rising. Infection triggers a complex and prolonged host response, in which both the innate and adaptive immune response are involved. The disturbance of immune system cells plays a key role in the induction of abnormal levels of immunoregulatory molecules. Furthermore, the involvement of effector immune system cells also impairs the host response to the infective agents and tissue damage. Recently, postmortem studies of patients who died of sepsis have provided important insights into why septic patients die and showed an extensive depletion of CD4 and CD8 lymphocytes and they found that circulating blood cells showed similar findings. Thus, the knowledge of the characterization of circulating lymphocyte abnormalities is relevant for the understanding of the sepsis pathophysiology. In addition, monitoring the immune response in sepsis, including circulating lymphocyte subsets count, appears to be potential biomarker for predicting the clinical outcome of the patient. This paper analyzes the lymphocyte involvement and dysfunction found in patients with sepsis and new opportunities to prevent sepsis and guide therapeutic intervention have been revealed.

    Full Text Available Background. Despite extensive research and an improved standard of care, sepsis remains a disorder with a high mortality rate. Sepsis is accompanied by severe metabolic alterations. Methods. We evaluated 117 patients with sepsis (severe sepsis [n=19] and septic shock [n=98] who were admitted to the intensive care unit. Serum cholesterol, triglyceride (TG, high-density lipoprotein (HDL, low-density lipoprotein (LDL, free fatty acid (FFA, and apolipoprotein (Apo A-I levels were measured on days 0, 1, 3, and 7. Results. Nonsurvivors had low levels of cholesterol, TG, HDL, LDL, and Apo A-I on days 0, 1, 3, and 7. In a linear mixed model analysis, the variations in TG, LDL, FFA, and Apo A-I levels over time differed significantly between the groups (p=0.043, p=0.020, p=0.005, and p=0.015, resp.. According to multivariate analysis, TG levels and SOFA scores were associated with mortality on days 0 and 1 (p=0.018 and p=0.008, resp.. Conclusions. Our study illustrated that TG levels are associated with mortality in patients with sepsis. This may be attributable to alterations in serum lipid metabolism during sepsis, thus modulating the host response to inflammation in critically ill patients.

    An increasing number of patients survive sepsis; however, we lack valid data on the long-term impact on morbidity from prospective observational studies. Therefore, we designed an observational cohort to quantify mid-term and long-term functional disabilities after intensive care unit (ICU)-treated sepsis. Ultimately, findings for the Mid-German Sepsis Cohort (MSC) will serve as basis for the implementation of follow-up structures for patients with sepsis and help to increase quality of care for sepsis survivors. All patients surviving ICU-treated sepsis are eligible and are recruited from five study centres in Germany (acute care hospital setting in Jena, Halle/Saale, Leipzig, Bad Berka, Erfurt; large long-term acute care hospital and rehabilitation setting in Klinik Bavaria Kreischa). Screening is performed by trained study nurses. Data are collected on ICU management of sepsis. On written informed consent provided by patients or proxies, follow-up is carried out by trained research staff at 3, 6 and 12 months and yearly thereafter. The primary outcome is functional disability as assessed by (instrumental) activities of daily living. Other outcomes cover domains like mortality, cognitive, emotional and physical impairment, and resource use. The estimated sample size of 3000 ICU survivors is calculated to allow detection of relevant changes in the primary outcome in sepsis survivors longitudinally. The study is conducted according to the current version of the Declaration of Helsinki and has been approved by four local/federal responsible institutional ethics committees and by the respective federal data protection commissioners. Results of MSC will be fed back to the patients and published in peer-reviewed journals.

    Full Text Available The leading pathophysiological changes during sepsis include systemic abnormalities in the immune
    response. Due to the general character of these disturbances, sepsis is usually studied as a homogenous clinical
    condition. We aimed to compare the immune response in intraabdominal sepsis (IAS and pneumonia-derived
    sepsis (PDS. The following cell populations were examined: white blood cell count (WBC, monocytes, lymphocytes:
    CD3+, CD4+ and CD8+ T cells, B cells, and NK cells. In both studied groups (i.e. IAS and PDS, the
    WBC was elevated. However, it was significantly higher in the IAS group than in the PDS group. The difference
    was due to a lower granulocyte count, as well as a lower monocyte count in PDS. We found no significant
    correlation between the total lymphocyte number and CD3+CD8+ T cells in either form of sepsis. Similarly, we
    observed no correlation between the total lymphocyte number and the NK cells subset in IAS. However, the
    numbers of CD3+CD8+ and NK cells correlated similarly in both types of sepsis. Both studied types of sepsis
    induced profound lymphocytopenia, with marked loss of CD8+ T cells and the NK cells. However, the similar
    relation between them, which was independent of the infection type, suggests that the NK and CD3+CD8+ cells
    have shared mechanisms of regulation. The primary site of infection has an impact on the global immune reaction.
    These alternations include especially myeloid cells: granulocytes and monocytes which disappear from peripheral
    blood during PDS, but increase in IAS.

    Prior sepsis studies evaluating antibiotic timing have shown mixed results. To evaluate the association between antibiotic timing and mortality among patients with sepsis receiving antibiotics within 6 hours of emergency department registration. Retrospective study of 35,000 randomly selected inpatients with sepsis treated at 21 emergency departments between 2010 and 2013 in Northern California. The primary exposure was antibiotics given within 6 hours of emergency department registration. The primary outcome was adjusted in-hospital mortality. We used detailed physiologic data to quantify severity of illness within 1 hour of registration and logistic regression to estimate the odds of hospital mortality based on antibiotic timing and patient factors. The median time to antibiotic administration was 2.1 hours (interquartile range, 1.4-3.1 h). The adjusted odds ratio for hospital mortality based on each hour of delay in antibiotics after registration was 1.09 (95% confidence interval [CI], 1.05-1.13) for each elapsed hour between registration and antibiotic administration. The increase in absolute mortality associated with an hour's delay in antibiotic administration was 0.3% (95% CI, 0.01-0.6%; P = 0.04) for sepsis, 0.4% (95% CI, 0.1-0.8%; P = 0.02) for severe sepsis, and 1.8% (95% CI, 0.8-3.0%; P = 0.001) for shock. In a large, contemporary, and multicenter sample of patients with sepsis in the emergency department, hourly delays in antibiotic administration were associated with increased odds of hospital mortality even among patients who received antibiotics within 6 hours. The odds increased within each sepsis severity strata, and the increased odds of mortality were greatest in septic shock.

    We proposed a review of present literature and systematic analysis of present literature to summarize the evidence on the use of β-blockers on the outcome of a patient with severe sepsis and septic shock. Medline, EMBASE, Cochrane Library were searched from 1946 to December 2013. The bibliography of all relevant articles was hand searched. Full-text search of the grey literature was done through the medical institution database. The database search identified a total of 1241 possible studies. The citation list was hand searched by both the authors. A total of 9 studies were identified. Most studies found a benefit from β-blocker administration in sepsis. This included improved heart rate (HR) control, decreased mortality and improvement in acid-base parameters. Chronic β-blocker usage in sepsis was also associated with improved mortality. The administration of β-blockers during sepsis was associated with better control of HR. The methodological quality of all the included studies, however, was poor. There is insufficient evidence to justify the routine use of β-blockers in sepsis. A large adequately powered multi-centered randomized controlled clinical trial is required to address the question on the efficacy of β-blocker usage in sepsis. This trial should also consider a number of important questions including the choice of β-blocker used, optimal dosing, timing of intervention, duration of intervention and discontinuation of the drug. Until such time based on the available evidence, there is no place for the use of β-blockers in sepsis in current clinical practice.

Addressing issues related to sepsis has been recognized as an important step towards reducing morbidity and mortality in developing countries, where the majority of the 7.5 million annual deaths in children under 5 years of age are considered to be secondary to sepsis. However, despite its prevalence, sepsis is largely neglected. Application of sepsis definitions created for use in resource-rich countries are neither practical nor feasible in most developing country settings, and alternative definitions designed for use in these settings need to be established. It has also been recognized that the inflammatory state created by sepsis increases the risk of post-discharge morbidity and mortality in developed countries, but exploration of this issue in developing countries is lacking. Research is urgently required to characterize better this potentially important issue.Keywords: children, pediatric sepsis, developing countries

    Pregnancy is associated with an increased risk of infection related to its associated mechanical and physiological changes. Sepsis remains among the top causes of maternal death worldwide and is associated with substantial maternal morbidity. However, there are sparse data on pregnancy-associated severe sepsis (PASS), related in part to infrequent reports, varying case definitions and methodological approach, small cohort size, and often limited focus on severe sepsis in selected phases of pregnancy outcomes. Available reports vary, but indicate that PASS is a rare but likely increasing complication, and it is more likely to develop with increased maternal age, among minority women, the poor, those lacking health insurance, those with chronic illness or pregnancy-associated complications, and following invasive procedures. Obstetric sites of infection are the most prevalent, but non-obstetric infections often underlie pregnancy-associated severe sepsis, though the source of infection is often not readily apparent during initial care. Women with PASS can have a rapidly fatal course and require heightened clinician vigilance for early diagnosis and timely effective intervention. Nevertheless, available reports raise concerns about prevalent substandard care of these patients, contributing to adverse outcomes. The case fatality of PASS appears lower than that in the general population with severe sepsis, while the long-term outcomes of survivors remain unknown.

    Full Text Available Objective: to evaluate the microcirculation system in critical conditions caused by abdominal sepsis for a further differentiated approach to intensive care. Subjects and methods. Twenty-four patients with abdominal sepsis (mean age 42.9±0.9 years were examined; a control group consisted of 35 apparently healthy individuals (mean age 40.1±2.1 years. Over 11 days, the microcirculatory bed was evaluated by cutaneous laser Doppler flowmetry by means of a ЛАКК-02 laser capillary blood flow analyzer made in the Russian Federation (LAZMA Research-and-Production Association, by using a basic light guide for percutaneous microcirculation studies. Results. Throughout the study, tissue blood perfusion remained in the patients with sepsis due to the higher effect of mainly active components of vascular tone regulation on the microvascular bed. In a poor outcome, there was a reduction in both active and passive regulatory effects on tissue perfusion chiefly due to local (myogenic factors. Conclusion. The findings suggest that the patients with sepsis have microcirculatory regulation changes aimed at maintaining tissue perfusion. A follow-up of the microcirculation may be useful in choosing intensive care tactics and predicting disease outcome.

    Despite advances in management over the last several decades, sepsis and acute respiratory distress syndrome (ARDS) still remain major clinical challenges and the leading causes of death for patients in intensive care units (ICUs) due to insufficient understanding of the pathophysiological mechanisms of these diseases. However, recent studies have shown that histones, also known as chromatin-basic structure proteins, could be released into the extracellular space during severe stress and physical challenges to the body (e.g., sepsis and ARDS). Due to their cytotoxic and proinflammatory effects, extracellular histones can lead to excessive and overwhelming cell damage and death, thus contributing to the pathogenesis of both sepsis and ARDS. In addition, antihistone-based treatments (e.g., neutralizing antibodies, activated protein C, and heparin) have shown protective effects and have significantly improved the outcomes of mice suffering from sepsis and ARDS. Here, we review researches related to the pathological role of histone in context of sepsis and ARDS and evaluate the potential value of histones as biomarkers and therapeutic targets of these diseases.

    This study was undertaken to observe the characteristics of blood pressure variability (BPV) and sepsis and to investigate changes in blood pressure and its value on the severity of illness in patients with sepsis. Blood parameters, APACHE II score, and 24-hour ambulatory BP were analyzed in 89 patients with sepsis. In patients with APACHE II score>19, the values of systolic blood pressure (SBPV), diasystolic blood pressure (DBPV), non-dipper percentage, cortisol (COR), lactate (LAC), platelet count (PLT) and glucose (GLU) were significantly higher than in those with APACHE II score ≤19 (Pblood cell (WBC), creatinine (Cr), PaO2, C-reactive protein (CRP), adrenocorticotropic hormone (ACTH) and tumor necrosis factor α (TNF-α) were not statistically significant (P>0.05). Correlation analysis showed that APACHE II scores correlated significantly with SBPV and DBPV (P0.05). Logistic regression analysis of SBPV, DBPV, APACHE II score, and LAC was used to predict prognosis in terms of survival and non-survival rates. Receiver operating characteristics curve (ROC) showed that DBPV was a better predictor of survival rate with an AUC value of 0.890. However, AUC of SBPV, APACHE II score, and LAC was 0.746, 0.831 and 0.915, respectively. The values of SBPV, DBPV and non-dipper percentage are higher in patients with sepsis. DBPV and SBPV can be used to predict the survival rate of patients with sepsis.

    Sepsis represents the host's systemic inflammatory response to a severe infection. It causes substantial human morbidity resulting in hundreds of thousands of deaths each year. Despite decades of intense research, the basic mechanisms still remain elusive. In either experimental animal models of sepsis or human patients, there are substantial physiological changes, many of which may result in subsequent organ injury. Variations in age, gender, and medical comorbidities including diabetes and renal failure create additional complexity that influence the outcomes in septic patients. Specific system-based alterations, such as the coagulopathy observed in sepsis, offer both potential insight and possible therapeutic targets. Intracellular stress induces changes in the endoplasmic reticulum yielding misfolded proteins that contribute to the underlying pathophysiological changes. With these multiple changes it is difficult to precisely classify an individual's response in sepsis as proinflammatory or immunosuppressed. This heterogeneity also may explain why most therapeutic interventions have not improved survival. Given the complexity of sepsis, biomarkers and mathematical models offer potential guidance once they have been carefully validated. This review discusses each of these important factors to provide a framework for understanding the complex and current challenges of managing the septic patient. Clinical trial failures and the therapeutic interventions that have proven successful are also discussed. PMID:23899564

    Sepsis is a significant cause of mortality and morbidity and is often associated with increased hospital resource utilization, prolonged intensive care unit (ICU) and hospital stay. The economic burden associated with sepsis is huge. With advances in medicine, there are now aggressive goal oriented treatments that can be used to help these patients. If we were able to predict which patients may be at risk for sepsis we could start treatment early and potentially reduce the risk of mortality and morbidity. Analytic methods currently used in clinical research to determine the risk of a patient developing sepsis may be further enhanced by using multi-modal analytic methods that together could be used to provide greater precision. Researchers commonly use univariate and multivariate regressions to develop predictive models. We hypothesized that such models could be enhanced by using multiple analytic methods that together could be used to provide greater insight. In this paper, we analyze data about patients with and without sepsis using a decision tree approach and a cluster analysis approach. A comparison with a regression approach shows strong similarity among variables identified, though not an exact match. We compare the variables identified by the different approaches and draw conclusions about the respective predictive capabilities,while considering their clinical significance.

    Sepsis continues to be a leading cause of mortality and morbidity in the intensive care unit. Cardiovascular dysfunction in sepsis is associated with worse short- and long-term outcomes. Sepsis-related myocardial dysfunction is noted in 20%-65% of these patients and manifests as isolated or combined left or right ventricular systolic or diastolic dysfunction. Echocardiography is the most commonly used modality for the diagnosis of sepsis-related myocardial dysfunction. With the increasing use of ultrasonography in the intensive care unit, there is a renewed interest in sepsis-related myocardial dysfunction. This review summarises the current scope of literature focused on sepsis-related myocardial dysfunction and highlights the use of basic and advanced echocardiographic techniques for the diagnosis of sepsis-related myocardial dysfunction and the management of sepsis and septic shock.

    The sepsis burden on acute care services in middle-income countries is a cause for concern. We estimated incidence, prevalence, and mortality of sepsis in adult Brazilian intensive care units (ICUs) and association of ICU organisational factors with outcome. We did a 1-day point prevalence study with follow-up of patients in ICU with sepsis in a nationally representative pseudo-random sample. We produced a sampling frame initially stratified by geographical region. Each stratum was then stratified by hospitals' main source of income (serving general public vs privately insured individuals) and ICU size (ten or fewer beds vs more than ten beds), finally generating 40 strata. In each stratum we selected a random sample of ICUs so as to enrol the total required beds in 1690 Brazilian adult ICUs. We followed up patients until hospital discharge censored at 60 days, estimated incidence from prevalence and length of stay, and generated national estimates. We assessed mortality prognostic factors using random-effects logistic regression models. On Feb 27, 2014, 227 (72%) of 317 ICUs that were randomly selected provided data on 2632 patients, of whom 794 had sepsis (30·2 septic patients per 100 ICU beds, 95% CI 28·4-31·9). The ICU sepsis incidence was 36·3 per 1000 patient-days (95% CI 29·8-44·0) and mortality was observed in 439 (55·7%) of 788 patients (95% CI 52·2-59·2). Low availability of resources (odds ratio [OR] 1·67, 95% CI 1·02-2·75, p=0·045) and adequacy of treatment (OR 0·56, 0·37-0·84, p=0·006) were independently associated with mortality. The projected incidence rate is 290 per 100 000 population (95% CI 237·9-351·2) of adult cases of ICU-treated sepsis per year, which yields about 420 000 cases annually, of whom 230 000 die in hospital. The incidence, prevalence, and mortality of ICU-treated sepsis is high in Brazil. Outcome varies considerably, and is associated with access to adequate resources and treatment. Our results show the

    Sepsis is a major healthcare problem and leading cause of death worldwide. UK hospital mortality statistics and payments for patient episodes of care are calculated on clinical coding data. The accuracy of these data depends on the quality of coding. This study aimed to investigate whether patients with significant bacteraemia are coded for sepsis and to estimate the financial costs of miscoding. Of 54 patients over a one-month period with a significant bacteraemia, only 19% had been coded for sepsis. This is likely to lead to falsely high calculated hospital mortality. Furthermore, this resulted in an underpayment of £21,000 for one month alone. Copyright © 2016 The Healthcare Infection Society. All rights reserved.

    Full Text Available Sepsis related coagulopathy ranges from mild laboratory alterations up to severe disseminated intravascular coagulation (DIC. There is evidence that DIC is involved in the pathogenesis of microvascular dysfunction contributing to organ failure. Additionally, the systemic activation of coagulation, by consuming platelets and coagulation factors, may cause bleeding. Thrombin generation via the tissue factor/factor VIIa route, contemporary depression of antithrombin and protein C anticoagulant system, as well as impaired fibrin degradation, due to high circulating levels of PAI-1, contribute to enhanced intravascular fibrin deposition. This deranged coagulopathy is an independent predictor of clinical outcome in patients with severe sepsis. Innovative supportive strategies aiming at the inhibition of coagulation activation comprise inhibition of tissue factor-mediated activation or restoration of physiological anticoagulant pathways, as the administration of recombinant human activated protein C or concentrate. In spite of some promising initial studies, additional trials are needed to define their clinical effectiveness in adults and children with severe sepsis.

    Introduction: Sepsis is a major problem in humans and both the incidence and mortality is increasing. Multiple microabcesses can be found in the brain of septic patients. Staphylococcus aureus is one of the most common causes of sepsis and brain abscesses. S. aureus is also a frequent cause...... of spontaneous porcine pyemia including endocarditis and associated brain lesions. We present a porcine model of haematogenous S. aureus induced brain infection. Materials and Methods: Twelve pigs received an intravenous injection of S. aureus of 108 CFU/kg body weight once at 0h or twice at 0h and 12h. Four...... pigs were kept as controls. The pigs were euthanized in groups of four at either 6, 12, 24 or 48 h post infection. The brain was collected from all the animals and examined histologically. Results: All the inoculated pigs developed sepsis and 7 out of 12 animals had microabscesses in the prosencephalon...

    Platelets play a critical role in vascular inflammation through the podoplanin and collagen/fibrin receptors, C-type-lectin-like-2 (CLEC-2) and glycoprotein VI (GPVI), respectively. Both receptors regulate endothelial permeability and prevent peri-vascular bleeding in inflammation. Here we show that platelet-specific deletion of CLEC-2 but not GPVI leads to enhanced systemic inflammation and accelerated organ injury in two mouse models of sepsis-intra-peritoneal lipopolysaccharide and cecal ligation and puncture. CLEC-2 deficiency is associated with reduced numbers of podoplanin-expressing macrophages despite increased cytokine and chemokine levels in the infected peritoneum. Pharmacological inhibition of the interaction between CLEC-2 and podoplanin regulates immune cell infiltration and the inflammatory reaction during sepsis, suggesting that activation of podoplanin underlies the anti-inflammatory action of platelet CLEC-2. We suggest podoplanin-CLEC-2 as a novel anti-inflammatory axis regulating immune cell recruitment and activation in sepsis.

    Sepsis is an infection-induced syndrome, mostly caused by bacteria, of organ dysfunctions that caused by host response dysregulations. One of the simplest sepsis-indicator is platelet and its indexes. A new platelet parameter called immature platelet count (IPF) became theinterest in this study. The study aims to see whether IPF could assess sepsis severity by procalcitonin (PCT).Sixty-four of seventy-one patients with increased PCT were included in this cross-sectional study and separated into three groups based on their PCT levels. IPF showed no significance among the three groups (p-value>0.05) while platelet count was significant (p-valuesepsis severity based on PCT showed larger platelet count, as the result of platelet destructions caused by pro-inflammatory cytokines and endotoxins.

    Aim: To evaluate renal volume and attenuation changes in patients with sepsis on contrast-enhanced computed tomography (CT) with respect to the severity of sepsis. Materials and methods: Forty-four patients with sepsis who underwent CT before and after the onset of sepsis were retrospectively analysed. Renal volume and CT attenuation value of the renal cortex on contrast-enhanced CT were measured for each patient and changes in renal volume and CT attenuation value from before to after the onset of sepsis were calculated. The changes were correlated with the severity of sepsis (Sepsis-related Organ Failure Assessment [SOFA] score). The time course of the renal volume and CT attenuation changes were also evaluated. Results: Renal volume increased by 17.6% and CT attenuation value decreased by 19% after the onset of sepsis with statistically significant differences (p<0.001 for both renal volume and CT attenuation changes). The renal volume and CT attenuation changes had significant correlations with the SOFA score (r=0.36, p=0.018 and −0.43, p=0.005, respectively). The time course of the renal volume and CT attenuation changes seemed to be gradual compared to that of the SOFA score and to lag behind the peak of the SOFA score. Conclusion: In patients with sepsis, the renal volume increases and the CT attenuation value decreases in proportion to the severity of sepsis. The changes may lag behind the peak of severity of sepsis and can be observed for a relatively long time after a patient's recovery from sepsis. - Highlights: • The renal volume increases and the renal enhancement on contrast-enhanced CT decreases in patients with sepsis. • The degrees of these changes are correlated with severity of sepsis. • These changes may lag behind the peak of severity of sepsis and last for a long time after a patient's recovery from sepsis.

    Sepsis is among the leading causes of morbidity, mortality, and cost overruns in critically ill patients. Early intervention with antibiotics improves survival in septic patients. However, no clinically validated system exists for real-time prediction of sepsis onset. We aimed to develop and validate an Artificial Intelligence Sepsis Expert algorithm for early prediction of sepsis. Observational cohort study. Academic medical center from January 2013 to December 2015. Over 31,000 admissions to the ICUs at two Emory University hospitals (development cohort), in addition to over 52,000 ICU patients from the publicly available Medical Information Mart for Intensive Care-III ICU database (validation cohort). Patients who met the Third International Consensus Definitions for Sepsis (Sepsis-3) prior to or within 4 hours of their ICU admission were excluded, resulting in roughly 27,000 and 42,000 patients within our development and validation cohorts, respectively. None. High-resolution vital signs time series and electronic medical record data were extracted. A set of 65 features (variables) were calculated on hourly basis and passed to the Artificial Intelligence Sepsis Expert algorithm to predict onset of sepsis in the proceeding T hours (where T = 12, 8, 6, or 4). Artificial Intelligence Sepsis Expert was used to predict onset of sepsis in the proceeding T hours and to produce a list of the most significant contributing factors. For the 12-, 8-, 6-, and 4-hour ahead prediction of sepsis, Artificial Intelligence Sepsis Expert achieved area under the receiver operating characteristic in the range of 0.83-0.85. Performance of the Artificial Intelligence Sepsis Expert on the development and validation cohorts was indistinguishable. Using data available in the ICU in real-time, Artificial Intelligence Sepsis Expert can accurately predict the onset of sepsis in an ICU patient 4-12 hours prior to clinical recognition. A prospective study is necessary to determine the

  13. Toxin Mediates Sepsis Caused by Methicillin-Resistant Staphylococcus epidermidis.

    Full Text Available Bacterial sepsis is a major killer in hospitalized patients. Coagulase-negative staphylococci (CNS with the leading species Staphylococcus epidermidis are the most frequent causes of nosocomial sepsis, with most infectious isolates being methicillin-resistant. However, which bacterial factors underlie the pathogenesis of CNS sepsis is unknown. While it has been commonly believed that invariant structures on the surface of CNS trigger sepsis by causing an over-reaction of the immune system, we show here that sepsis caused by methicillin-resistant S. epidermidis is to a large extent mediated by the methicillin resistance island-encoded peptide toxin, PSM-mec. PSM-mec contributed to bacterial survival in whole human blood and resistance to neutrophil-mediated killing, and caused significantly increased mortality and cytokine expression in a mouse sepsis model. Furthermore, we show that the PSM-mec peptide itself, rather than the regulatory RNA in which its gene is embedded, is responsible for the observed virulence phenotype. This finding is of particular importance given the contrasting roles of the psm-mec locus that have been reported in S. aureus strains, inasmuch as our findings suggest that the psm-mec locus may exert effects in the background of S. aureus strains that differ from its original role in the CNS environment due to originally "unintended" interferences. Notably, while toxins have never been clearly implied in CNS infections, our tissue culture and mouse infection model data indicate that an important type of infection caused by the predominant CNS species is mediated to a large extent by a toxin. These findings suggest that CNS infections may be amenable to virulence-targeted drug development approaches.

    Full Text Available Objective To investigate the distribution characteristics of organs with liquid sequestration during fluid resuscitation in rats with sepsis. Methods Fifty male Wistar rats were randomly divided into five groups: control group (n=10, sepsis group (n=10, crystalloid group (n=10, albumin group (n=10, and artificial colloid (HAES group (n=10. The sepsis model was reproduced by cecal ligation and puncture. The mean arterial pressure was monitored with carotid artery intubation. Twelve hours after fluid infusion by micro-infusion pump via the femoral vein, tissues from the heart, liver, lungs, kidney (right, and small intestine were harvested to observe the pathological changes and calculate the tissue water content. Results The water content of every visceral tissue was higher in the sepsis group than in the control group (P < 0.05; the water content in the heart, liver, and lung tissues was higher in the albumin group than in the crystalloid group (P < 0.05. The water content in both albumin and crystalloid groups was higher than that in the sepsis group (P < 0.05. Moreover, the water content in the heart, liver, and lungs in the HAES group was lower than that in the crystalloid and albumin groups (P < 0.05. Cellular injuries were more severe in the heart, liver, and lungs than in the intestine and kidney in the crystalloid group and albumin group under electron-microscope. Conclusion Liquid sequestration exists mainly in the lungs, heart, and liver of rats with sepsis during fluid resuscitation. The phenomenon is less evident in the kidney and small intestine. Artificial colloid can reduce capillary leak with a good volume expansion effect.

    Sepsis-triggered immune paralysis including T-cell dysfunction increase susceptibility to infection. Gamma interferon (IFNg) exert beneficial effects in patients with sepsis. Herein, we speculated that IFNg may attenuate T-cell dysfunction induced by sepsis, although the mechanisms remain elusive. To test this hypothesis, we used a model based on cecal ligation and puncture (CLP) to induce sepsis in mice. Male C57BL/6 mice were pretreated with recombinant human IFNg (0.01μg/g of body weight) before CLP. The immunophenotyping of cell surface receptor expression, and regulatory T cells (CD4+CD25+Foxp3+) were quantified by flow cytometry. Immunohistochemical staining was performed to evaluate the loss of immune effector cells. Formation of IFNg and interleukin 4 (IL-4) in the spleen and plasma levels of TNF-α, IL-6, high-mobility group box 1 (HMGB1) were determined using enzyme-linked immunosorbent assay. IFNg markedly inhibited the reduction in cytokine secretion from lipopolysaccharide (LPS)-stimulated splenocytes. IFNg-treated mices had significantly decreased percentages of programmed cell death 1 (PD-1) receptors, increased the percentages of positive costimulatory receptor CD28 on CD4 T cells expressing. IFNg markedly reduced T-cell apoptosis through upregulating the expression of Bcl-2. CLP-induced formation of regulatory T cells in the spleen was abolished in IFNg -treated mices. Moreover, IFNg treatment reduced plasma levels of TNF-α, IL-6, HMGB1. IFNg can be a powerful regulator of immune function under sepsis conditions. Therefore, targeted immune-enhancement with IFNg may be a valid therapeutic approach in sepsis. Copyright © 2017 Elsevier Inc. All rights reserved.

    There is limited literature on neonatal bacterial sepsis in New World (NW) camelids. Bacterial culture-positive crias have clinical differences based on the specific bacterial genera isolated. Bacterial culture-positive NW camelid crias blood gas abnormalities, potentially complicating diagnosis. Affected crias may not have localizing signs at presentation and are not usually febrile, although hypothermia, tachypnea, and tachycardia are relatively common. Total protein concentration was not a substitute for immunoglobulin G measurement in septic crias in this study. Familiarity with the clinical presentation and common pathogens isolated should improve early recognition and treatment and ultimately outcome of crias with sepsis.

    Sepsis-associated encephalopathy (SAE), a complication of sepsis, is often complicated by acute and long-term brain dysfunction. SAE is associated with electroencephalogram pattern changes and abnormal neuroimaging findings. The major processes involved are neuroinflammation, circulatory dysfunction, and excitotoxicity. Neuroinflammation and microcirculatory alterations are diffuse, whereas excitotoxicity might occur in more specific structures involved in the response to stress and the control of vital functions. A dysfunction of the brainstem, amygdala, and hippocampus might account for the increased mortality, psychological disorders, and cognitive impairment. This review summarizes clinical and paraclinical features of SAE and describes its mechanisms at cellular and structural levels. Copyright © 2016 Elsevier Inc. All rights reserved.

Se conformaron 2 grupos de estudio: a Ventilados (26 pacientes y b No ventilados (60 pacientes, entre los que no existían diferencias con respecto a sexo, peso, edad gestacional, pero sí en cuanto al puntaje de Apgar y correspondieron los valores más bajos de éste a los ventilados. No hubo diferencias entre ambos grupos de estudio con respecto a la evolución del neurodesarrollo, pero se detectó una mayor proporción de secuelas neurológicas severas en el grupo de ventilados con relación a los no ventilados (19,2 vs 1,7 %. Las alteraciones del neurodesarrollo más frecuentemente encontradas en los ventilados fueron dentro de las ligeras: la hiperactividad, las alteraciones reflejas, los trastornos transitorios del tono muscular y el retraso ligero del lenguaje.

    Progranulin, a widely expressed protein, has multiple physiological functions. The functional role of progranulin in the host response to sepsis remains unknown. To assess the role of progranulin in the host response to sepsis. Effects of progranulin on host response to sepsis were determined. Progranulin concentrations were significantly elevated in adult (n = 74) and pediatric (n = 26) patients with sepsis relative to corresponding healthy adult (n = 36) and pediatric (n = 17) control subjects, respectively. By using a low-lethality model of nonsevere sepsis, we observed that progranulin deficiency not only increased mortality but also decreased bacterial clearance during sepsis. The decreased host defense to sepsis in progranulin-deficient mice was associated with reduced macrophage recruitment, with correspondingly impaired chemokine CC receptor ligand 2 (CCL2) production in peritoneal lavages during the early phase of sepsis. Progranulin derived from hematopoietic cells contributed to host defense in sepsis. Therapeutic administration of recombinant progranulin not only rescued impaired host defense in progranulin-deficient mice after nonsevere sepsis but also protected wild-type mice against a high-lethality model of severe sepsis. Progranulin-mediated protection against sepsis was closely linked to improved peritoneal macrophage recruitment. In addition, CCL2 treatment of progranulin-deficient mice improved survival and decreased peritoneal bacterial loads during sepsis, at least in part through promotion of peritoneal macrophage recruitment. This proof-of-concept study supports a central role of progranulin-dependent macrophage recruitment in host defense to sepsis, opening new opportunities to host-directed therapeutic strategy that manipulate host immune response in the treatment of sepsis.

    There is a need for a clear and actionable definition of maternal sepsis, in order to better assess the burden of this condition, trigger timely and effective treatment and allow comparisons across facilities and countries. The objective of this study was to review maternal sepsis definitions and identification criteria and to report on the results of an expert consultation to develop a new international definition of maternal sepsis. All original and review articles and WHO documents, as well as clinical guidelines providing definitions and/or identification criteria of maternal sepsis were included. A multidisciplinary international panel of experts was surveyed through an online consultation in March-April 2016 on their opinion on the existing sepsis definitions, including new definition of sepsis proposed for the adult population (2016 Third International Consensus Definitions for Sepsis and Septic Shock) and importance of different criteria for identification of maternal sepsis. The definition was agreed using an iterative process in an expert face-to-face consensus development meeting convened by WHO and Jhpiego. Standardizing the definition of maternal sepsis and aligning it with the current understanding of sepsis in the adult population was considered a mandatory step to improve the assessment of the burden of maternal sepsis by the expert panel. The literature review and expert consultation resulted in a new WHO consensus definition "Maternal sepsis is a life-threatening condition defined as organ dysfunction resulting from infection during pregnancy, child-birth, post-abortion, or post-partum period". Plans are in progress to validate the new WHO definition of maternal sepsis in a large international population. The operationalization of the new maternal sepsis definition requires generation of a set of practical criteria to identify women with sepsis. These criteria should enable clinicians to focus on the timely initiation of actionable elements of

    Olenick, Evelyn M; Zimbro, Kathie S; DʼLima, Gabrielle M; Ver Schneider, Patricia; Jones, Danielle

    The Sepsis "Sniffer" Algorithm (SSA) has merit as a digital sepsis alert but should be considered an adjunct to versus an alternative for the Nurse Screening Tool (NST), given lower specificity and positive predictive value. The SSA reduced the risk of incorrectly categorizing patients at low risk for sepsis, detected sepsis high risk in half the time, and reduced redundant NST screens by 70% and manual screening hours by 64% to 72%. Preserving nurse hours expended on manual sepsis alerts may translate into time directed toward other patient priorities.

    Sepsis, iron loading, and aging cause independent increases in gut epithelial and splenic apoptosis. It is unknown how their combination will affect apoptosis and systemic cytokine levels. Hfe-/- mice (a murine homologue of hemochromatosis) abnormally accumulate iron in their tissues. Aged (24-26 months) or mature (16-18 months) Hfe-/- mice and wild type (WT) littermates were subjected to cecal ligation and puncture (CLP) or sham laparotomy. Intestine, spleen, and blood were harvested 24 h later and assessed for apoptosis and cytokine levels. Gut epithelial and splenic apoptosis were low in both aged septic and sham Hfe-/- mice, regardless of the amount of iron in their diet. Mature septic WT mice had increased apoptosis compared to age-matched sham WT mice. Mature septic Hfe-/- mice had similar levels of intestinal cell death to age-matched septic WT mice but higher levels of splenic apoptosis. Apoptosis was significantly lower in septic aged Hfe-/- mice than septic mature Hfe-/- animals. Interleukin-6 was elevated in septic aged Hfe-/- mice compared to sham mice. Although sepsis, chronic iron dysregulation, and aging each increase gut and splenic apoptosis, their combination yields cell death levels similar to sham animals despite the fact that aged Hfe-/- mice are able to mount an inflammatory response following CLP and mature Hfe-/- mice have elevated sepsis-induced apoptosis. Combining sepsis with two risk factors that ordinarily increase cell death and increase mortality in CLP yields an apoptotic response that could not have been predicted based upon each element in isolation.

    Objective(s) In the last few years, serum procalcitonin has been proposed as an early marker of infections in neonates, with varying results. In this study, we aimed to investigate the value of procalcitonin, and C- reactive protein in establishing the diagnosis of neonatal sepsis. Materials and Methods Blood samples were collected at admission from 69 neonates with suspected infection (admitted to the Neonatal Intensive Care Units at Alzahra and Dr Beheshti Hospital in and Fatema-Zahra in Najafabad from May 2005 to April 2006). Patients were categorized in different groups according to clinical symptoms of sepsis, bacteriological and laboratory results. Group I consisted of 20 newborns with positive blood cultures and other biological tests which suggested infection. Group II consisted of 49 neonates with negative blood cultures but had two or three of clinical signs of sepsis. The control group included 18 healthy neonates with physiological hyperbilirubinemia and no clinical and biological data of infection, referred to the hospital for bilirubin determination. Procalcitonin and C-reactive protein (CRP) were determined by immunoluminometric assay and nephlometry method respectively. Results Mean levels of procalcitonin and CRP in septic neonates (group I) were significantly higher than the other two groups (P< 0.005). Sensitivity, specificity, positive predictive value and negative predictive value were determined for all markers and compared with each other. Conclusion We conclude that procalcitonin is a better marker than CRP in the diagnosis of neonatal sepsis. PMID:23493845

    Full Text Available Objective: to evaluate the efficiency of extracorporeal detoxification techniques in patients with abdominal sepsis. Subjects and methods. Three hundred and seventy-nine patients with acute generalized peritonitis were examined. Extracorporeal detoxifying techniques were used during conventional therapy in Group 1 (n=319; the other patients received only traditional therapy (a control group. The time course of changes in the parameters of toxemia, a hemostasiogram, and an immunogram were examined. Results. The study indicated significantly reduced endotoxemia and better blood aggregation resulting from the use of plasmapheresis, cryoplasmasorption, and plasmasorption, as well as stimulated immunity when the above techniques were combined with autoblood photomodification and extracorporeal immunopharmacotherapy in patients with abdominal sepsis. In severe abdominal sepsis and infectious-toxic shock, there was regression of multiple organ dysfunction and lower mortality when venovenous hemofiltration was applied. Conclusion. A differential approach to using active detoxifying techniques is needed, by taking into account the severity of the disease. Key words: abdominal sepsis, detoxifying techniques.

    To review the accuracy of the pediatric consensus definition of sepsis in term neonates and to determine the definition of neonatal sepsis used. The review focused primarily on pediatric literature relevant to the topic of interest. Neonatal sepsis is variably defined based on a number of clinical and laboratory criteria that make the study of this common and devastating condition very difficult. Diagnostic challenges and uncertain disease epidemiology necessarily result from a variable definition of disease. In 2005, intensivists caring for children recognized that as new drugs became available, children would be increasingly studied and thus, pediatric-specific consensus definitions were needed. Pediatric sepsis criteria are not accurate for term neonates and have not been examined in preterm neonates for whom the developmental stage influences aberrations associated with host immune response. Thus, specific consensus definitions for both term and preterm neonates are needed. Such definitions are critical for the interpretation of observational studies, future training of scientists and practitioners, and implementation of clinical trials in neonates.

    2010-12-01

    Sepsis and acute lung injury continue to be major causes of morbidity and mortality worldwide despite advances in our understanding of pathophysiology and the discovery of new management strategies. Recent investigations show that stem cells may be beneficial as prognostic biomarkers and novel therapeutic strategies in these syndromes. This article reviews the potential use of endogenous adult tissue-derived stem cells in sepsis and acute lung injury as prognostic markers and also as exogenous cell-based therapy. A directed systematic search of the medical literature using PubMed and OVID, with particular emphasis on the time period after 2002, was done to evaluate topics related to 1) the epidemiology and pathophysiology of sepsis and acute lung injury; and 2) the definition, characterization, and potential use of stem cells in these diseases. DATA SYNTHESIS AND FINDINGS: When available, preferential consideration was given to prospective nonrandomized clinical and preclinical studies. Stem cells have shown significant promise in the field of critical care both for 1) prognostic value and 2) treatment strategies. Although several recent studies have identified the potential benefit of stem cells in sepsis and acute lung injury, further investigations are needed to more completely understand stem cells and their potential prognostic and therapeutic value.

    The purpose of this study was to define the relationship in polymicrobial sepsis (in adult male C57BL/6 mice) between heart dysfunction and the appearance in plasma of extracellular histones. Procedures included induction of sepsis by cecal ligation and puncture and measurement of heart function using echocardiogram/Doppler parameters. We assessed the ability of histones to cause disequilibrium in the redox status and intracellular [Ca(2+)]i levels in cardiomyocytes (CMs) (from mice and rats). We also studied the ability of histones to disturb both functional and electrical responses of hearts perfused with histones. Main findings revealed that extracellular histones appearing in septic plasma required C5a receptors, polymorphonuclear leukocytes (PMNs), and the Nacht-, LRR-, and PYD-domains-containing protein 3 (NLRP3) inflammasome. In vitro exposure of CMs to histones caused loss of homeostasis of the redox system and in [Ca(2+)]i, as well as defects in mitochondrial function. Perfusion of hearts with histones caused electrical and functional dysfunction. Finally, in vivo neutralization of histones in septic mice markedly reduced the parameters of heart dysfunction. Histones caused dysfunction in hearts during polymicrobial sepsis. These events could be attenuated by histone neutralization, suggesting that histones may be targets in the setting of sepsis to reduce cardiac dysfunction. © FASEB.

  14. VIP as a potential therapeutic agent in gram negative sepsis.

    Ibrahim, Hiba; Barrow, Paul; Foster, Neil

    2012-12-01

    Gram negative sepsis remains a high cause of mortality and places a great burden on public health finance in both the developed and developing world. Treatment of sepsis, using antibiotics, is often ineffective since pathology associated with the disease occurs due to dysregulation of the immune system (failure to return to steady state conditions) which continues after the bacteria, which induced the immune response, have been cleared. Immune modulation is therefore a rational approach to the treatment of sepsis but to date no drug has been developed which is highly effective, cheap and completely safe to use. One potential therapeutic agent is VIP, which is a natural peptide and is highly homologous in all vertebrates. In this review we will discuss the effect of VIP on components of the immune system, relevant to gram negative sepsis, and present data from animal models. Furthermore we will hypothesise on how these studies could be improved in future and speculate on the possible different ways in which VIP could be used in clinical medicine.

    Objective: To study the patterns of causative bacteria and antibiotic resistance in neonatal sepsis. Results: Among 228 cases included in the study, the male to female ratio was 2.1 to 1. The gestational age was less than 36 weeks in 68 (30%) cases and low birth weight babies were 143 (62.6%). History of birth asphyxia was present in 103 (45%) cases. There were 142 (62.3%) cases of early onset ( 7 days). Out of 233 positive blood cultures Escherichia coli was found to be commonest (47.8%, n =111, p<0.05) both in early onset (47.8%, n=68, p <0.05) and late onset sepsis (47.3%,n=43, p<0.05). Staphylococcus aureus was the most common among gram positive organism. Resistance to cefotaxime, ceftazidime and amikacin was 34% to 80% and to ciprofloxacin 13% to 72%. A total of 64 cases (28%) died. Mortality was four times higher in early onset sespis. Conclusion: Gram negative bacteria are the commenst cause of neonatal sepsis. The resistance to the commonly used antibiotics is alarmingly high. Mortality is four times higher in early one set sepsis. (author)

    The relationship between sepsis-induced CNS dysfunction and changes in brain blood flow remains unknown, and animal studies examining the influence of sepsis on cerebral blood flow (CBF) do not satisfactorily address that relationship. We measured CBF and cerebrovascular reactivity to CO 2 in nine patients with sepsis syndrome using the 133 Xe clearance technique. Mean CBF was 29.6 +/- 15.8 (SD) ml/100 g.min, significantly lower than the normal age-matched value in this laboratory of 44.9 +/- 6.2 ml/100 g.min (p less than .02). This depression did not correlate with changes in mean arterial pressure. Despite the reduction in CBF, the specific reactivity of the cerebral vasculature to changes in CO 2 was normal, 1.3 +/- 0.9 ml/100 g.min/mm Hg. Brain blood flow is reduced in septic humans; the contribution of this reduction to the metabolic and functional changes observed in sepsis requires further study

    Sepsis and other infections are associated with late cardiovascular events. Although persistent inflammation is implicated, a causal relationship has not been established. We tested whether sepsis causes vascular inflammation and accelerates atherosclerosis. We performed prospective, randomized animal studies at a university research laboratory involving adult male ApoE-deficient (ApoE-/-) and young C57B/L6 wild-type (WT) mice. In the primary study conducted to determine whether sepsis accelerates atherosclerosis, we fed ApoE-/- mice (N = 46) an atherogenic diet for 4 months and then performed cecal ligation and puncture (CLP), followed by antibiotic therapy and fluid resuscitation or a sham operation. We followed mice for up to an additional 5 months and assessed atheroma in the descending aorta and root of the aorta. We also exposed 32 young WT mice to CLP or sham operation and followed them for 5 days to determine the effects of sepsis on vascular inflammation. ApoE-/- mice that underwent CLP had reduced activity during the first 14 days (38% reduction compared to sham; P < 0.001) and sustained weight loss compared to the sham-operated mice (-6% versus +9% change in weight after CLP or sham surgery to 5 months; P < 0.001). Despite their weight loss, CLP mice had increased atheroma (46% by 3 months and 41% increase in aortic surface area by 5 months; P = 0.03 and P = 0.004, respectively) with increased macrophage infiltration into atheroma as assessed by immunofluorescence microscopy (0.52 relative fluorescence units (rfu) versus 0.97 rfu; P = 0.04). At 5 months, peritoneal cultures were negative; however, CLP mice had elevated serum levels of interleukin 6 (IL-6) and IL-10 (each at P < 0.05). WT mice that underwent CLP had increased expression of intercellular adhesion molecule 1 in the aortic lumen versus sham at 24 hours (P = 0.01) that persisted at 120 hours (P = 0.006).

    Full Text Available The Surviving Sepsis Campaign (SSC guidelines describe best practice for the management of severe sepsis and septic shock in developed countries, but most deaths from sepsis occur where healthcare is not sufficiently resourced to implement them. Our objective was to define the feasibility and basis for modified guidelines in a resource-restricted setting.We undertook a detailed assessment of sepsis management in a prospective cohort of patients with severe sepsis caused by a single pathogen in a 1,100-bed hospital in lower-middle income Thailand. We compared their management with the SSC guidelines to identify care bundles based on existing capabilities or additional activities that could be undertaken at zero or low cost. We identified 72 patients with severe sepsis or septic shock associated with S. aureus bacteraemia, 38 (53% of who died within 28 days. One third of patients were treated in intensive care units (ICUs. Numerous interventions described by the SSC guidelines fell within existing capabilities, but their implementation was highly variable. Care available to patients on general wards covered the fundamental principles of sepsis management, including non-invasive patient monitoring, antimicrobial administration and intravenous fluid resuscitation. We described two additive care bundles, one for general wards and the second for ICUs, that if consistently performed would be predicted to improve outcome from severe sepsis.It is feasible to implement modified sepsis guidelines that are scaled to resource availability, and that could save lives prior to the publication of international guidelines for developing countries.

    To identify the barriers to implementation of the Sepsis Six pathway. Research has suggested that compliance with the Sepsis Six pathway remains low. A convenience sample of doctors and nurses from one emergency department, two medical wards and two surgical wards were asked to complete a survey questionnaire. Data from 108 respondents were available for analysis. Doctors and nurses agreed that lack of sepsis recognition during observation rounds and failure to associate sepsis with deranged temperature and blood results acted as barriers to the identification of sepsis. Doctors and nurses agreed that nursing delays and knowledge deficits were the top barriers leading to delay in sepsis treatment. Knowledge deficits, lack of resources and practical issues were barriers identified in this survey. This will inform the educational and process needs of both doctors and nurses in order to improve sepsis care.

    Sepsis is common, often fatal and requires rapid interventions to improve outcomes. While the optimal management of sepsis in the intensive care setting is the focus of extensive research interest, the mainstay of the recognition and initial management of sepsis will occur outside the intensive care setting. Therefore, it is key that institutions and clinicians remain well informed of the current updates in sepsis management and continue to use them to deliver appropriate and timely interventions to enhance patient survival. This review discusses the latest updates in sepsis care including the new consensus definition of sepsis, the outcome of the proCESS, ProMISe and ARISE trials of early goal directed therapy (EGDT), and the most recent guidelines from the Surviving Sepsis Campaign. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available Sepsis, a systemic inflammatory response to infection, is the major cause of death in intensive care units (ICUs. The mortality rate of sepsis remains high even though the treatment and understanding of sepsis both continue to improve. Sinomenine (SIN is a natural alkaloid extracted from Chinese medicinal plant Sinomenium acutum, and its hydrochloride salt (Sinomenine hydrochloride, SIN-HCl is widely used to treat rheumatoid arthritis (RA. However, its role in sepsis remains unclear. In the present study, we investigated the role of SIN-HCl in sepsis induced by cecal ligation and puncture (CLP in BALB/c mice and the corresponding mechanism. SIN-HCl treatment improved the survival of BALB/c mice that were subjected to CLP and reduced multiple organ dysfunction and the release of systemic inflammatory mediators. Autophagy activities were examined using Western blotting. The results showed that CLP-induced autophagy was elevated, and SIN-HCl treatment further strengthened the autophagy activity. Autophagy blocker 3-methyladenine (3-MA was used to investigate the mechanism of SIN-HCl in vitro. Autophagy activities were determined by examining the autophagosome formation, which was shown as microtubule-associated protein light chain 3 (LC3 puncta with green immunofluorescence. SIN-HCl reduced lipopolysaccharide (LPS-induced inflammatory cytokine release and increased autophagy in peritoneal macrophages (PM. 3-MA significantly decreased autophagosome formation induced by LPS and SIN-HCl. The decrease of inflammatory cytokines caused by SIN-HCl was partially aggravated by 3-MA treatment. Taken together, our results indicated that SIN-HCl could improve survival, reduce organ damage, and attenuate the release of inflammatory cytokines induced by CLP, at least in part through regulating autophagy activities.

    Full Text Available Sepsis is one of the major causes of death and is the biggest obstacle preventing improvement of the success rate in curing critical illnesses. Currently, isotonic solutions are used in fluid resuscitation technique. Several studies have shown that hypertonic saline applied in hemorrhagic shock can rapidly increase the plasma osmotic pressure, facilitate the rapid return of interstitial fluid into the blood vessels, and restore the effective circulating blood volume. Here, we established a rat model of sepsis by using the cecal ligation and puncture approach. We found that intravenous injection of hypertonic saline dextran (7.5% NaCl/6% dextran after cecal ligation and puncture can improve circulatory failure at the onset of sepsis. We found that the levels of tumor necrosis factor-α, interleukin-1β, interleukin-6 and intracellular adhesion molecule 1 levels in the lung tissue of cecal ligation and puncture rats treated with hypertonic saline dextran were significantly lower than the corresponding levels in the control group. We inferred that hypertonic saline dextran has a positive immunoregulatory effect and inhibits the overexpression of the inflammatory response in the treatment of sepsis. The percentage of neutrophils, lung myeloperoxidase activity, wet to dry weight ratio of lung tissues, histopathological changes in lung tissues, and indicators of arterial blood gas analysis was significantly better in the hypertonic saline dextran-treated group than in the other groups in this study. Hypertonic saline dextran-treated rats had significantly improved survival rates at 9 and 18 h compared to the control group. Our results suggest that hypertonic saline dextran plays a protective role in acute lung injury caused after cecal ligation and puncture. In conclusion, hypertonic/hyperoncotic solutions have beneficial therapeutic effects in the treatment of an animal model of sepsis.

    To provide a series of recommendations based on the best available evidence to guide clinicians providing nursing care to patients with severe sepsis. Modified Delphi method involving international experts and key individuals in subgroup work and electronic-based discussion among the entire group to achieve consensus. We used the Surviving Sepsis Campaign guidelines as a framework to inform the structure and content of these guidelines. We used the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system to rate the quality of evidence from high (A) to very low (D) and to determine the strength of recommendations, with grade 1 indicating clear benefit in the septic population and grade 2 indicating less confidence in the benefits in the septic population. In areas without complete agreement between all authors, a process of electronic discussion of all evidence was undertaken until consensus was reached. This process was conducted independently of any funding. Sixty-three recommendations relating to the nursing care of severe sepsis patients are made. Prevention recommendations relate to education, accountability, surveillance of nosocomial infections, hand hygiene, and prevention of respiratory, central line-related, surgical site, and urinary tract infections, whereas infection management recommendations related to both control of the infection source and transmission-based precautions. Recommendations related to initial resuscitation include improved recognition of the deteriorating patient, diagnosis of severe sepsis, seeking further assistance, and initiating early resuscitation measures. Important elements of hemodynamic support relate to improving both tissue oxygenation and macrocirculation. Recommendations related to supportive nursing care incorporate aspects of nutrition, mouth and eye care, and pressure ulcer prevention and management. Pediatric recommendations relate to the use of antibiotics, steroids, vasopressors and

    Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly and remains among the most challenging ICU-managed disease. Beside severe pulmonary hypertension, lung hypoplasia and major abdominal surgery, infective complications remain major determinants of outcome. However, the specific incidence of sepsis as well as associated risk factors is unknown. This prospective, 4-year observational study took place in the pediatric intensive care and neonatal medicine department of the Paris South University Hospitals (Le Kremlin-Bicêtre, France), CDH national referral center and involved 62 neonates with CDH. During their ICU stay, 28 patients (45%) developed 38 sepsis episodes. Ventilator-associated pneumonia (VAP: 23/38; 31.9 VAP per 1000 days of mechanical ventilation) and central line-associated blood stream infections (CLABSI: 5/38; 5.5 per 1000 line days) were the most frequently encountered infections. Multivariate analysis showed that gestational age at birth and intra-thoracic position of liver were significantly associated with the occurrence of sepsis. Infected patients had longer duration of mechanical and noninvasive ventilation (16.2 and 5.8 days, respectively), longer delay to first feeding (1.2 days) and a longer length of stay in ICU (23 days), but there was no difference in mortality. Healthcare-associated infections, and more specifically VAP, are the main infective threat in children with CDH. Sepsis has a significant impact on the duration of ventilator support and ICU length of stay but does not impact mortality. Low gestational age and intra-thoracic localization of the liver are two independent risk factors associated with sepsis.

    Justification: Pediatric sepsis is a commonly encountered global issue. Existing guidelines for sepsis seem to be applicable to the developed countries, and only few articles are published regarding application of these guidelines in the developing countries, especially in resource-limited countries such as India and Africa. Process: An expert representative panel drawn from all over India, under aegis of Intensive Care Chapter of Indian Academy of Pediatrics (IAP) met to discuss and draw guidelines for clinical practice and feasibility of delivery of care in the early hours in pediatric patient with sepsis, keeping in view unique patient population and limited availability of equipment and resources. Discussion included issues such as sepsis definitions, rapid cardiopulmonary assessment, feasibility of early aggressive fluid therapy, inotropic support, corticosteriod therapy, early endotracheal intubation and use of positive end expiratory pressure/mechanical ventilation, initial empirical antibiotic therapy, glycemic control, and role of immunoglobulin, blood, and blood products. Objective: To achieve a reasonable evidence-based consensus on the basis of published literature and expert opinion to formulating clinical practice guidelines applicable to resource-limited countries such as India. Recommendations: Pediatric sepsis guidelines are presented in text and flow chart format keeping resource limitations in mind for countries such as India and Africa. Levels of evidence are indicated wherever applicable. It is anticipated that once the guidelines are used and outcomes data evaluated, further modifications will be necessary. It is planned to periodically review and revise these guidelines every 3–5 years as new body of evidence accumulates. PMID:20606908

    The Center for Medicare and Medicaid Services adopted the Early Management Bundle, Severe Sepsis/Septic Shock (SEP-1) performance measure to the Hospital Inpatient Quality Reporting Program in July 2015 to help address the high mortality and high cost associated with sepsis. The SEP-1 performance measure requires, among other critical interventions, timely administration of antibiotics to patients with sepsis or septic shock. The multistakeholder workgroup recognizes the need for SEP-1 but strongly believes that multiple antibiotics listed in the antibiotic tables for SEP-1 are not appropriate and the use of these antibiotics, as called for in the SEP-1 measure, is not in alignment with prudent antimicrobial stewardship. To promote the appropriate use of antimicrobials and combat antimicrobial resistance, the workgroup provides recommendations for appropriate antibiotics for the treatment of sepsis. © The Author 2017.

    The Sepsis-3 Task Force updated the clinical criteria for sepsis, excluding the need for systemic inflammatory response syndrome (SIRS) criteria. The clinical implications of the proposed flowchart including the quick Sequential (Sepsis-related) Organ Failure Assessment (qSOFA) and SOFA scores are unknown. To perform a clinical decision-making analysis of Sepsis-3 in patients with community-acquired pneumonia. This was a cohort study including adult patients with community-acquired pneumonia from two Spanish university hospitals. SIRS, qSOFA, the Confusion, Respiratory Rate and Blood Pressure (CRB) score, modified SOFA (mSOFA), the Confusion, Urea, Respiratory Rate, Blood Pressure and Age (CURB-65) score, and Pneumonia Severity Index (PSI) were calculated with data from the emergency department. We used decision-curve analysis to evaluate the clinical usefulness of each score and the primary outcome was in-hospital mortality. Of 6,874 patients, 442 (6.4%) died in-hospital. SIRS presented the worst discrimination, followed by qSOFA, CRB, mSOFA, CURB-65, and PSI. Overall, overestimation of in-hospital mortality and miscalibration was more evident for qSOFA and mSOFA. SIRS had lower net benefit than qSOFA and CRB, significantly increasing the risk of over-treatment and being comparable with the "treat-all" strategy. PSI had higher net benefit than mSOFA and CURB-65 for mortality, whereas mSOFA seemed more applicable when considering mortality/intensive care unit admission. Sepsis-3 flowchart resulted in better identification of patients at high risk of mortality. qSOFA and CRB outperformed SIRS and presented better clinical usefulness as prompt tools for patients with community-acquired pneumonia in the emergency department. Among the tools for a comprehensive patient assessment, PSI had the best decision-aid tool profile.

    Newborn sepsis is one of the major public health concerns worldwide. Also in our neonatal care unit, it is one of the major problems and especially infections with Enterobacteriaceae were noted to pose an increasing problem in the last years. Data collection was done retrospectively for 2011. Early onset sepsis was defined as having a positive blood culture within 72 h and late onset sepsis after 72 h of delivery. Out of 599 patients being admitted, 58 newborns were assessed having a neonatal sepsis. Of these 58 newborns with sepsis, 11 were diagnosed within 72 h post delivery (early onset) and 47 were diagnosed after 72 h post delivery (late onset). The percentage of Enterobacteriaceae causing late onset sepsis was 57.5 %. Among these, Klebsiella pneumoniae could be isolated in 29.8 %, Enterobacter cloacae in 12.8 %, Enterobacter aerogenes in 8.5 %, and Escherichia coli in 6.4 % of late onset sepsis. Majority of the strains showed a resistance to antibiotics used in empiric treatment. Antibiotic prophylaxis/treatment from birth until the onset of late onset sepsis could be analyzed in 20 out of 27 newborns with late onset sepsis caused by Enterobacteriaceae. A regimen of empirical antibiotic treatment containing aminopenicillin and/or gentamicin was administered in 16 newborns and that of cephalosporin in 14 out of 20 newborns for at least 5 days before onset of sepsis. The association of empiric long-term antibiotic treatment and the high number of late onset sepsis with often multiresistant Enterobacteriaceae might be causal and urges for a change in general antibiotic prophylaxis/treatment in newborns admitted to the neonatal care unit of our hospital.

    The consensus definition of severe sepsis requires suspected or proven infection, organ failure, and signs that meet two or more criteria for the systemic inflammatory response syndrome (SIRS). We aimed to test the sensitivity, face validity, and construct validity of this approach. We studied data from patients from 172 intensive care units in Australia and New Zealand from 2000 through 2013. We identified patients with infection and organ failure and categorized them according to whether they had signs meeting two or more SIRS criteria (SIRS-positive severe sepsis) or less than two SIRS criteria (SIRS-negative severe sepsis). We compared their characteristics and outcomes and assessed them for the presence of a step increase in the risk of death at a threshold of two SIRS criteria. Of 1,171,797 patients, a total of 109,663 had infection and organ failure. Among these, 96,385 patients (87.9%) had SIRS-positive severe sepsis and 13,278 (12.1%) had SIRS-negative severe sepsis. Over a period of 14 years, these groups had similar characteristics and changes in mortality (SIRS-positive group: from 36.1% [829 of 2296 patients] to 18.3% [2037 of 11,119], P<0.001; SIRS-negative group: from 27.7% [100 of 361] to 9.3% [122 of 1315], P<0.001). Moreover, this pattern remained similar after adjustment for baseline characteristics (odds ratio in the SIRS-positive group, 0.96; 95% confidence interval [CI], 0.96 to 0.97; odds ratio in the SIRS-negative group, 0.96; 95% CI, 0.94 to 0.98; P=0.12 for between-group difference). In the adjusted analysis, mortality increased linearly with each additional SIRS criterion (odds ratio for each additional criterion, 1.13; 95% CI, 1.11 to 1.15; P<0.001) without any transitional increase in risk at a threshold of two SIRS criteria. The need for two or more SIRS criteria to define severe sepsis excluded one in eight otherwise similar patients with infection, organ failure, and substantial mortality and failed to define a transition point in

  1. Arterial versus venous lactate: a measure of sepsis in children.

    This study assessed the agreement between arterial and venous blood lactate and pH levels in children with sepsis. This retrospective, three-year study involved 60 PICU patients, with data collected from electronic or paper patient records. The inclusion criteria comprised of children (≤17 years old) with sepsis and those who had a venous blood gas taken first with an arterial blood gas taken after within one hour. The lactate and pH values measured through each method were analysed. There is close agreement between venous and arterial lactate up to 2 mmol/L. As this value increases, this agreement becomes poor. The limits of agreement (LOA) are too large (±1.90 mmol/L) to allow venous and arterial lactate to be used interchangeably. The mean difference and LOA between both methods would be much smaller if derived using lactate values under 2.0 mmol/L. There is close agreement between arterial and venous pH (MD = -0.056, LOA ± 0.121). However, due to extreme variations in pH readings during sepsis, pH alone is an inadequate marker. A venous lactate ≤2 mmol/L can be used as a surrogate for arterial lactate during early management of sepsis in children. However, if the value exceeds 2 mmol/L, an arterial sample must confirm the venous result. What is known: • In children with septic shock, a blood gas is an important test to show the presence of acidosis and high lactic acid. Hyperlactataemia on admission is an early predictor of outcome and is associated with a greater mortality risk. • An arterial sample is the standard for lactate measurement, however getting a sample may be challenging in the emergency department or a general paediatric ward. Venous samples are quicker and easier to obtain. Adult studies generally advise caution in replacing venous lactate values for the arterial standard, whilst paediatric studies are limited in this area. What is new: • This is the first study assessing the agreement between arterial and peripheral venous

    Sepsis remains the leading cause of death in the surgical intensive care unit. Prior studies have demonstrated a survival benefit of remote ischemic conditioning (RIC) in many disease states. The aim of this study was to determine the effects of RIC on survival in sepsis in an animal model and to assess alterations in inflammatory biochemical profiles. We hypothesized that RIC alters inflammatory biochemical profiles resulting in decreased mortality in a septic mouse model. Eight to 12 week C57BL/6 mice received intra-peritoneal injection of 12.5-mg/kg lipopolysaccharide (LPS). Septic animals in the experimental group underwent RIC at 0, 2, and 6 h after LPS by surgical exploration and alternate clamping of the femoral artery. Six 4-min cycles of ischemia-reperfusion were performed. Primary outcome was survival at 5-d after LPS injection. Secondary outcome was to assess the following serum cytokine levels: interferon-γ (IFN-γ), interleukin (IL)-10, IL-1β, and tumor necrosis factoralpha (TNFα) at the baseline before LPS injection, 0 hour after LPS injection, and at 2, 4, 24 hours after induction of sepsis (RIC was performed at 2 h after LPS injection). Kaplan-Meier survival analysis and log-rank test were used. ANOVA test was used to compare cytokine measurements. We performed experiments on 44 mice: 14 sham and 30 RIC mice (10 at each time point). Overall survival was higher in the experimental group compared to the sham group (57% versus 21%; P = 0.02), with the highest survival rate observed in the 2-hour post-RIC group (70%). On Kaplan-Meier analysis, 2-h post-RIC group had increased survival at 5 days after LPS (P = 0.04) with hazard ratio of 0.3 (95% confidence interval = 0.09-0.98).

    The study on the degree of agreement among three established sepsis diagnosis criteria become the necessity to investigate the best sepsis diagnosis criteria in Indonesia further. A cross-sectional study of adult Emergency Room patients hospitalized with a diagnosis of infection in CiptoMangunkusumo Hospital, Indonesia was conducted during March and April 2017. We recorded diagnosis, gender, age, comorbidities, infection source, and origin. Every subject was classified into sepsis and non-sepsis based on 1991, 2001 and sepsis-3 criteria. Raw % and Kappa agreement coefficients (κ) were calculated according to previously established formula to measure the degree of agreement among three diagnostic criteria. As many as 278 subjects were included in this study. The raw % agreement and κ between 1991 and 2001 criteria is 69.07% and 0.34 respectively. The raw % agreement and κ between 2001 and sepsis-3 criteria is 56.12% and 0.15 respectively. The raw % agreement and κ between 1991 and sepsis-3 criteria is 48.19% and -0.02. In conclusions, there is afair agreement between 1991 and 2001 criteria, poor agreement between 2001 and sepsis-3 criteria, and poor disagreement between 1991 and sepsis-3 criteria. This necessitates further Indonesian study of the best diagnosis criteria to diagnose an infected patient with sepsis.

    Full Text Available Sepsis is a major healthcare problem and current estimates suggest that the incidence of sepsis is approximately 750,000 annually. Sepsis is caused by an inability of the immune system to eliminate invading pathogens. It was recently proposed that endogenous mediators produced during sepsis can contribute to the immune dysfunction that is observed in sepsis. Endocannabinoids that are produced excessively in sepsis are potential factors leading to immune dysfunction, because they suppress immune cell function by binding to G-protein-coupled CB(2 receptors on immune cells. Here we examined the role of CB(2 receptors in regulating the host's response to sepsis.The role of CB(2 receptors was studied by subjecting CB(2 receptor wild-type and knockout mice to bacterial sepsis induced by cecal ligation and puncture. We report that CB(2 receptor inactivation by knockout decreases sepsis-induced mortality, and bacterial translocation into the bloodstream of septic animals. Furthermore, CB(2 receptor inactivation decreases kidney and muscle injury, suppresses splenic nuclear factor (NF-kappaB activation, and diminishes the production of IL-10, IL-6 and MIP-2. Finally, CB(2 receptor deficiency prevents apoptosis in lymphoid organs and augments the number of CD11b(+ and CD19(+ cells during CLP.Taken together, our results establish for the first time that CB(2 receptors are important contributors to septic immune dysfunction and mortality, indicating that CB(2 receptors may be therapeutically targeted for the benefit of patients suffering from sepsis.

    Patients surviving sepsis demonstrate sustained inflammation, which has been associated with long-term complications. One of the main mechanisms behind sustained inflammation is a metabolic switch in parenchymal and immune cells, thus understanding metabolic alterations after sepsis may provide important insights to the pathophysiology of sepsis recovery. In this study, we explored metabolomics in a novel Drosophila melanogaster model of surviving sepsis using Nuclear Magnetic Resonance (NMR), to determine metabolite profiles. We used a model of percutaneous infection in Drosophila melanogaster to mimic sepsis. We had three experimental groups: sepsis survivors (infected with Staphylococcus aureus and treated with oral linezolid), sham (pricked with an aseptic needle), and unmanipulated (positive control). We performed metabolic measurements seven days after sepsis. We then implemented metabolites detected in NMR spectra into the MetExplore web server in order to identify the metabolic pathway alterations in sepsis surviving Drosophila. Our NMR metabolomic approach in a Drosophila model of recovery from sepsis clearly distinguished between all three groups and showed two different metabolomic signatures of inflammation. Sham flies had decreased levels of maltose, alanine, and glutamine, while their level of choline was increased. Sepsis survivors had a metabolic signature characterized by decreased glucose, maltose, tyrosine, beta-alanine, acetate, glutamine, and succinate. PMID:28009836

    Under "Rory's Regulations," New York State Article 28 acute care hospitals were mandated to implement sepsis protocols and report patient-level data. This study sought to determine how well cases reported under state mandate align with discharge records in a statewide administrative database. Observational cohort study. First 27 months of mandated sepsis reporting (April 1, 2014, to June 30, 2016). Hospitalizations with sepsis at New York State Article 28 acute care hospitals. Sepsis regulations with mandated reporting. We compared cases reported to the New York State Department of Health Sepsis Clinical Database with discharge records in the Statewide Planning and Research Cooperative System database. We classified discharges as 1) "coded sepsis discharges"-a diagnosis code for severe sepsis or septic shock and 2) "possible sepsis discharges," using Dombrovskiy and Angus criteria. Of 111,816 sepsis cases reported to the New York State Department of Health Sepsis Clinical Database, 105,722 (94.5%) were matched to discharge records in Statewide Planning and Research Cooperative System. The percentage of coded sepsis discharges reported increased from 67.5% in the first quarter to 81.3% in the final quarter of the study period (mean, 77.7%). Accounting for unmatched cases, as many as 82.7% of coded sepsis discharges were potentially reported, whereas at least 17.3% were unreported. Compared with unreported discharges, reported discharges had higher rates of acute organ dysfunction (e.g., cardiovascular dysfunction 63.0% vs 51.8%; p New York State Department of Health Sepsis Clinical Database. Incomplete reporting appears to be driven more by underrecognition than attempts to game the system, with minimal bias to risk-adjusted hospital performance measurement.

  9. Sepsis Induces a Dysregulated Neutrophil Phenotype That Is Associated with Increased Mortality

    Full Text Available Background. Neutrophil dysfunction in sepsis has been implicated in the pathogenesis of multiorgan failure; however, the role of neutrophil extracellular traps (NETs remains uncertain. We aimed to determine the sequential changes in ex vivo NETosis and its relationship with mortality in patients with sepsis and severe sepsis. Methods. This was a prospective observational cohort study enrolling 21 healthy age-matched controls and 39 sepsis and 60 severe sepsis patients from acute admissions to two UK hospitals. Patients had sequential bloods for the ex vivo assessment of NETosis in response to phorbol-myristate acetate (PMA using a fluorometric technique and chemotaxis using time-lapse video microscopy. Continuous data was tested for normality, with appropriate parametric and nonparametric tests, whilst categorical data was analysed using a chi-squared test. Correlations were performed using Spearman’s rho. Results. Ex vivo NETosis was reduced in patients with severe sepsis, compared to patients with sepsis and controls (p=0.002. PMA NETosis from patients with septic shock was reduced further (p<0.001 compared to controls. The degree of metabolic acidosis correlated with reduced NETosis (p<0.001, and this was replicated when neutrophils from healthy donors were incubated in acidotic media. Reduced NETosis at baseline was associated with an increased 30-day (p=0.002 and 90-day mortality (p=0.014 in sepsis patients. These findings were accompanied by defects in neutrophil migration and delayed apoptosis. Resolution of sepsis was not associated with the return to baseline levels of NETosis or migration. Conclusions. Sepsis induces significant changes in neutrophil function with the degree of dysfunction corresponding to the severity of the septic insult which persists beyond physiological recovery from sepsis. The changes induced lead to the failure to effectively contain and eliminate the invading pathogens and contribute to sepsis

    OBJECTIVE: In the present hypothesis-generating study, we investigated whether spontaneous blood pressure oscillations are suppressed to lower frequencies, and whether abolished oscillations are associated with an adverse outcome in mechanically ventilated patients with sepsis. METHODS: We...... retrospectively subjected invasive steady-state blood pressure recordings from 65 mechanically ventilated patients with sepsis to spectral analysis. Modified spectral bands were visually identified by plotting spectral power against frequency. RESULTS: Modified middle-frequency and low-frequency (MF' and LF......') oscillations were absent in 9% and 22% of the patients, respectively. In patients in whom spontaneous blood pressure oscillations were preserved, the MF' oscillations occurred at 0.021 Hz (median, interquartile range 0.013-0.030), whereas the LF' oscillations occurred at 0.009 Hz (median, interquartile range 0...

    Full Text Available Acute renal failure (ARF is a common complication of sepsis and carries a high mortality. Renal replacement therapy (RRT during the acute stage is the mainstay of therapy. Va-rious modalities of RRT are available. Continuous RRT using convective methods are preferred in sepsis-induced ARF, especially in hemodynamically unstable patients, although clear evidence of benefit over intermittent hemodialysis is still not available. Peritoneal dialysis is clearly inferior, and is not recommended. Early initiation of RRT is probably advantageous, although the optimal timing of dialysis is yet unknown. Higher doses of RRT are more likely to be beneficial. Use of bio-compatible membranes and bicarbonate buffer in the dialysate are preferred. Anticoagulation during dialysis must be carefully adjusted and monitored.

    A full term, previously normal 2 1/2-month-old black boy was transferred to our hospital from an outlying facility on hospital day 5 for failure to thrive. Three weeks before transfer, the infant was hospitalized for a diarrheal illness with fever. The baby received 3 days of ceftriaxone empirically and was discharged home after the sepsis evaluation was negative. Mild diarrhea and steady weight loss continued and the baby was readmitted. Blood culture done on admission grew Flavobacterium meningosepticum, an organism previously described as an uncommon cause of sepsis in neonates and immunocompromised individuals. As it is water-borne, it has been associated with infection via contaminated water. This organism is usually resistant to antibiotics commonly used for empiric treatment. To our knowledge, this is the first reported case of Flavobacterium bacteremia associated with a prodromal and concurrent diarrheal illness.

    Perianal sepsis with ecthyma gangrenosum is a severe and potentially mutilating complication in immunocompromised children. Therapies include antimicrobial treatment, incision and drainage, generous tissue debridement, and skin transplantation. We describe 3 children with acute lymphoblastic leukemia having sepsis with Pseudomonas aeruginosa in febrile neutropenia and severe perianal infections treated relatively early with a protective colostomy. Indications for colostomy were nonhealing wounds, and ceaseless pain. All patients showed a rapid reduction of pain. Complete wound healing was seen in 2 patients, and considerable pain reduction and increased quality of life were seen in a third patient during palliative care. These results suggest that a protective colostomy should be considered early in the management of immunocompromised children with ecthyma gangrenosum.

    Rocky Mountain spotted fever (RMSF) is a disease caused by the Gram-negative coccobacillus Rickettsia ricketsii which has been on the rise since the last decade in the USA. The symptoms are common to the many viral diseases, and the classic triad of fever, rash and headache is not always present when RMSF is diagnosed. It may progress to severe cases such as renal failure, disseminated intravascular coagulation and septicaemia. This report aims to present a fulminant case of RMSF associated with sepsis. It describes a female patient's case that quickly progressed to sepsis and death. The patient showed non-specific symptoms for 5 days before being admitted to a hospital. The fact that she lived in an area highly infested with Amblyomma aureolatum ticks was unknown to the medical staff until the moment she died.

  2. Effect of bacterial sepsis on gluconeogenic capacity in the rat

    1988-01-01

    Since sepsis places increased demands on the host for energy and on other substrates for tissue repair and host defense, hepatic gluconeogenesis is critical for the host's adaptation to sepsis. Substrate-stimulated gluconeogenesis (i.e., gluconeogenic capacity) was assessed by the alanine load method in mannoheptulose-pretreated rats made septic by cecal ligation after laparotomy, as well as by cecal ligation and puncture after laparotomy. Fasted rats subjected to laparotomy only (sham-ligated) and fasted, nonoperated rats (controls) were investigated simultaneously. Following an overnight (-18 to 0 hr) fast, nonoperated animals converted 17.9 +/- 1.5% of [ 14 C]alanine to [ 14 C]glucose. Continued fasting in nonoperated animals resulted in enhanced (P less than 0.05) gluconeogenic capacity (6 hr = 27.2 +/- 3.0%; 24 hr = 26.2 +/- 1.9%; and 48 hr = 28.5 +/- 2.6%) relative to Time 0. Laparotomy alone (sham ligation) delayed the fasting-induced increase (P less than 0.05) in gluconeogenesis capacity (6 hr = 21.1 +/- 1.2%; 24 hr = 18.5 +/- 1.3%; 48 hr = 27.8 +/- 1.0%) relative to Time 0. In contrast, postoperative sepsis produced a sustained depression (P less than 0.05) of gluconeogenic capacity relative to nonoperated sham-ligated controls at 48 hr (cecal ligation, 18.4 +/- 1.4%; and cecal ligation and puncture, 18.8 +/- 1.2%). Thus, (1) fasting enhances hepatic gluconeogenic capacity; (2) surgical trauma transiently blunts the gluconeogenic response to fasting; and (3) sepsis undermines the gluconeogenic response to fasting

    The role of extracorporeal therapies (ECTs) in sepsis is unclear and is a strongly debated topic in critical-care medicine. Unfortunately, much of this debate arises because we lack a clear understanding of what defines the stage and severity of the disease, and the pivotal pathophysiological events dictating outcomes. In the absence of this knowledge, ECTs remain among a large group of therapies with high promise but unproven efficacy.

    To investigate the potential additive effects of blood transfusion and sepsis on colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival after colon cancer surgery. Perioperative blood transfusions are associated with infectious complications and increased risk of cancer recurrence through systemic inflammatory effects. Furthermore, recent studies have suggested an association among sepsis, subsequent systemic inflammation, and adverse cardiovascular outcomes. However, no study has investigated the association among transfusion, sepsis, and disease-specific survival in postoperative patients. The New York State Cancer Registry and Statewide Planning and Research Cooperative System were queried for stage I to III colon cancer resections from 2004 to 2011. Propensity-adjusted survival analyses assessed the association of perioperative allogeneic blood transfusion, sepsis, and 5-year colon cancer disease-specific survival, cardiovascular disease-specific survival, and overall survival. Among 24,230 patients, 29% received a transfusion and 4% developed sepsis. After risk adjustment, transfusion and sepsis were associated with worse colon cancer disease-specific survival [(+)transfusion: hazard ratio (HR) 1.19, 95% confidence interval (CI) 1.09-1.30; (+)sepsis: HR 1.84, 95% CI 1.44-2.35; (+)transfusion/(+)sepsis: HR 2.27, 95% CI 1.87-2.76], cardiovascular disease-specific survival [(+)transfusion: HR 1.18, 95% CI 1.04-1.33; (+)sepsis: HR 1.63, 95% CI 1.14-2.31; (+)transfusion/(+)sepsis: HR 2.04, 95% CI 1.58-2.63], and overall survival [(+)transfusion: HR 1.21, 95% CI 1.14-1.29; (+)sepsis: HR 1.76, 95% CI 1.48-2.09; (+)transfusion/(+)sepsis: HR 2.36, 95% CI 2.07-2.68] relative to (-)transfusion/(-)sepsis. Additional analyses suggested an additive effect with those who both received a blood transfusion and developed sepsis having even worse survival. Perioperative blood transfusions are associated with shorter survival

    Epidural use has been associated with a higher rate of neonatal sepsis evaluation. Epidural-related fever explains some of the increase but not the excess of neonatal sepsis evaluations in afebrile women We studied 1109 women who had singleton term pregnancies and who presented in spontaneous labor and were afebrile during labor (24 hours or sustained fetal heart rate of >160 beats per minute. Minor criteria included a maternal temperature of 99.6 degrees F to 100.4 degrees F, rupture of membranes for 12 to 24 hours, maternal admission white blood cell count of >15 000 cells/mL(3), or an Apgar score of 24 hours (6.2% vs 3.4%), low-grade fever of 99.6 degrees F to 100.4 degrees F (24.3% vs 5.2%), and rupture of membranes for 12 to 24 hours (21.4% vs 5.2%) than women without epidural. Epidural analgesia is associated with increased rates of major and minor criteria for neonatal sepsis evaluations in afebrile women.

    This study assessed the extent and mechanism of complement activation in community-acquired sepsis at presentation to the emergency department (ED) and following 24 hours of quantitative resuscitation. A prospective pilot study of patients with severe sepsis and healthy controls was conducted among individuals presenting to a tertiary care ED. Resuscitation, including antibiotics and therapies to normalize central venous and mean arterial pressure (MAP) and central venous oxygenation, was performed on all patients. Serum levels of Factor Bb (alternative pathway), C4d (classical and mannose-binding lectin [MBL] pathway), C3, C3a, and C5a were determined at presentation and 24 hours later among patients. Twenty patients and 10 healthy volunteer controls were enrolled. Compared to volunteers, all proteins measured were abnormally higher among septic patients (C4d 3.5-fold; Factor Bb 6.1-fold; C3 0.8-fold; C3a 11.6-fold; C5a 1.8-fold). Elevations in C5a were most strongly correlated with alternative pathway activation. Surprisingly, a slight but significant inverse relationship between illness severity (by sequential organ failure assessment [SOFA] score) and C5a levels at presentation was noted. Twenty-four hours of structured resuscitation did not, on average, affect any of the mediators studied. Patients with community-acquired sepsis have extensive complement activation, particularly of the alternative pathway, at the time of presentation that was not significantly reversed by 24 hours of aggressive resuscitation.

    Full Text Available Thyroid storm is a rare but life-threatening condition, which can be induced by many critical diseases. We reported a 40-year-old woman with thyroid goiter manifesting with acute sepsis-induced hyperthyroidism. She mainly presented with abdominal bloating, diarrhea, lower limbs edema and exertional dyspnea. The lactate was 9.5 mmol/L and procalcitonin was 3.8 ng/mL, suggesting acute sepsis. The thyroid echo showed bilateral thyroid goiter. Relevant data included a thyroid-stimulating hormone level of 0.03 μIU/mL; free tetraiodothyronine, 5.67 ng/dL; thyroid-stimulating hormone receptor antibody, 76.9% (normal range, < 14%; and antimicrosomal antibody titer, 1:102400 (normal range, < 1:100, suggesting toxic goiter with thyroid storm. Piperacillin/tazobactam, methimazole and Lugol's iodine achieved a good outcome. The symptoms of early sepsis and those of thyroid storm could be similar. Therefore, a careful history taking, a thorough physical examination and a high degree of suspicion could make early diagnosis and appropriate treatment.

    The CT imaging and clinical presentation in 14 children with coexistent intracranial sepsis and sinusitis were reviewed. A routine CT head scan (10-mm thick semi-axial slices through the cranium done before and after intravenous contrast medium administration) was found to be an inadequate initial investigation as the intracranial collection was missed in four patients and the abnormal sinuses not shown in six. In half the children the dagnosis of sinusitis was unsuspected at the time of admission. The dominant clinical features were fever, intense headache and facial swelling in early adolescent males. In this clinical setting we recommend: (1) The routine scan is extended through the frontal and ethmoidal sinuses and photographed at a window level and width showing both bone detail and air/soft tissue interfaces; (2) direct coronal projections are performed through the anterior cranial fossa if no collection is seen on the routine study; (3) an early repeat scan within 48 h if the initial study shows no intracranial pathology but the fronto-ethomoidal sinuses are abnormal and there is a high clinical supicion of intracranial sepsis; and (4) in the presence of intracranial sepsis the vault is viewed at bone window settings to exclude cranial osteomyelitis.

    Full Text Available Despite advances in modern medicine, sepsis remains a complex syndrome that has been associated with significant morbidity and mortality. Multiple organ failure associated with sepsis leads to high mortality and morbidity. About 28 - 50% deaths have been reported in patients with sepsis. The number of sepsis patients is increasing, with considerable burden on healthcare facilities. Various factors leading to a rise in the incidence of sepsis are (1 Improvement of diagnostic procedures (2 Increase in the number of immunocompromised patients taking treatment for various autoimmune disease, carcinomas, organ transplantation (3 Advances in intensive procedures (4 Nosocomial infections (5 Extensive use of antibiotics. With the better understanding of sepsis various modalities to modify pathophysiological response of septic patients have developed. Activated protein C and low-dose corticosteroid therapy have been tried in patients, with variable results.

    The rate of pediatric severe sepsis is reported to be on the rise in the United States, increasing by approximately 6000 cases annually. The goal of this study was to determine the rate of pediatric sepsis per 100 000 inpatient discharges over time. The 2006, 2009, and 2012 Agency for Healthcare Research and Quality Healthcare Cost Utilization Project Kid's Inpatient Databases were used to analyze the rate of sepsis in children over time. The rate of pediatric sepsis has increased over time from 92.8 per 100 000 in 2006 to 158.7 per 100 000 in 2012. Children less than a year old with Medicaid coverage and 3 or more procedures during hospitalization have significantly higher rates than their counterparts. This study helps clarify the population demographics that are at greater risk for sepsis infections. Understanding the at-risk population aids policymakers and care providers in targeting these populations and make drastic changes to sepsis policies.

    The prognosis for late-onset sepsis depends largely on a timely diagnosis. We assess central-peripheral temperature difference monitoring as a marker for late-onset neonatal sepsis diagnosis. We performed a prospective, observational study focusing on a cohort of 129 very low-birth-weight infants. Thermal gradient alteration was defined as a difference of > 2°C maintained during 4 hours. We then determined its association with the late-onset sepsis variable through logistic regression. We enrolled 129 preterm babies in 52 months. Thermal gradient alterations showed an adjusted odds ratio for late-onset sepsis of 23.60 (95% confidence interval [CI], 6.80-81.88), with a sensitivity of 83% and negative predictive value of 94%. In 71% of cases, thermal gradient alteration was the first clinical sign of sepsis, while C-reactive protein was peripheral temperature differences are an early sign of evolving late-onset sepsis.

    Infectious diseases and sepsis, as a severe and potential medical condition in which the immune system overreacts and finally turns against itself, are a worldwide problem. As a matter of fact, it is considered the main cause of mortality in intensive care. For such a pathology, a timely diagnosis is essential, since it has been shown that each hour of delay in the administration of an effective pharmacological treatment increases the mortality rate of 7%. Therefore, the advent of a POCT platform for sepsis is highly requested by physicians. Biomarkers have gained importance for the diagnosis and treatment monitoring of septic patients, since biomarkers can indicate the severity of sepsis and can differentiate bacterial from viral and fungal infection, and systemic sepsis from local infection. The present paper deals with the development of fluorescence-based bioassays for the sepsis biomarkers and their integration on a multianalyte chip. Among the different biomarker candidates, the attention was focused on procalcitonin (PCT), C-reactive protein (CRP) and interleukine-6 (IL-6) as well as on soluble urokinase plasminogen activator receptor (suPAR) recently proposed as a very effective inflammatory marker, potentially capable of acting also as a prognostic biomarker. Starting point of this new setup was an already developed fluorescence-based optical platform, which makes use of multichannel polymethylmetacrylate chips for the detection of different bioanalytes, and the serial interrogation of the microfluidic channels of the chip. The novel proposed optical setup makes use of a suitable fluorescence excitation and detection scheme, capable of performing the simultaneous interrogation of all the channels. For the excitation part of the optical setup, a diffractive optical element is used which generates a pattern of parallel lines, for the simultaneous excitation of all the channels and for the optimization of the optical power distribution. For the detection part

    In spite of over half a century of research, sepsis still constitutes a major problem in health care delivery. Although advances in research have significantly increased our knowledge of the pathogenesis of sepsis and resulted in better prognosis and improved survival outcome, sepsis still remains a major challenge in modern medicine with an increase in occurrence predicted and a huge socioeconomic burden. It is generally accepted that sepsis is due to an initial hyperinflammatory response. However, numerous efforts aimed at targeting the proinflammatory cytokine network have been largely unsuccessful and the search for novel potential therapeutic targets continues. Recent studies provide compelling evidence that dysregulated anti-inflammatory responses may also contribute to sepsis mortality. Our previous studies on the role of regulatory T cells and phosphoinositide 3-kinases in sepsis highlight immunological approaches that could be explored for sepsis therapy. In this article, we review the current and emerging concepts in sepsis, highlight novel potential therapeutic targets and immunological approaches for sepsis treatment and propose a biphasic treatment approach for management of the condition. © 2016 S.

    Annually affecting over 18 million people worldwide, sepsis is common, deadly, and costly. Despite significant effort by the Surviving Sepsis Campaign and other initiatives, sepsis remains underrecognized and undertreated. Research indicates that educating providers may improve sepsis diagnosis and treatment; thus, the Stanford School of Medicine has developed a mobile-accessible, case-based, online game entitled Septris (http://med.stanford.edu/septris/). Septris, launched online worldwide in December 2011, takes an innovative approach to teaching early sepsis identification and evidence-based management. The free gaming platform leverages the massive expansion over the past decade of smartphones and the popularity of noneducational gaming.The authors sought to assess the game's dissemination and its impact on learners' sepsis-related knowledge, skills, and attitudes. In 2012, the authors trained Stanford pregraduate (clerkship) and postgraduate (resident) medical learners (n = 156) in sepsis diagnosis and evidence-based practices via 20 minutes of self-directed game play with Septris. The authors administered pre- and posttests. By October 2014, Septris garnered over 61,000 visits worldwide. After playing Septris, both pre- and postgraduate groups improved their knowledge on written testing in recognizing and managing sepsis (P game scores with sepsis knowledge.

    Several diagnostic methods for the evaluation and monitoring were used to find out the pro-inflammatory status, as well as incidence of sepsis in critically ill patients. One such recent method is based on investigating the genetic polymorphisms and determining the molecular and genetic links between them, as well as other sepsis-associated pathophysiologies. Identification of genetic polymorphisms in critical patients with sepsis can become a revolutionary method for evaluating and monitoring these patients. Similarly, the complications, as well as the high costs associated with the management of patients with sepsis, can be significantly reduced by early initiation of intensive care.

    Abstract Decreased ADAMTS 13 activity has been reported in severe sepsis and in sepsis-induced disseminated intravascular coagulation. This study aimed to investigate the role of ADAMTS 13 in different pediatric sepsis syndromes and evaluate its relationship with disease severity and outcome. We prospectively collected cases of sepsis treated in a pediatric intensive care unit, between July 2012 and June 2014 in Chang Gung Children's Hospital in Taoyuan, Taiwan. Clinical characteristics and ADAMTS-13 activity were analyzed. All sepsis syndromes had decreased ADAMTS 13 activity on days 1 and 3 of admission compared to healthy controls. Patients with septic shock had significantly decreased ADAMTS 13 activity on days 1 and 3 compared to those with sepsis and severe sepsis. There was a significant negative correlation between ADAMTS 13 activity on day 1 and day 1 PRISM-II, PELOD, P-MOD, and DIC scores. Patients with mortality had significantly decreased ADAMTS 13 activity on day 1 than survivors, but not on day 3. Different pediatric sepsis syndromes have varying degrees of decreased ADAMTS 13 activity. ADAMTS 13 activity is strongly negatively correlated with disease severity of pediatric sepsis syndrome, whereas decreased ADAMTS 13 activity on day 1 is associated with increased risk of mortality.

    Long noncoding RNAs (lncRNAs) are becoming promising biomarker candidates in various diseases as assessed via sequencing technologies. Sepsis is a life-threatening disease without ideal biomarkers. The aim of this study was to investigate the expression profile of lncRNAs in the peripheral blood of sepsis patients and to find potential biomarkers of sepsis. A lncRNA expression profile was performed using peripheral blood from three sepsis patients and three healthy volunteers using microarray screening. The differentially expressed lncRNAs were validated by real-time quantitative polymerase chain reaction (qRT-PCR) in a further set of 22 sepsis patients and 22 healthy volunteers. Among 1316 differentially expressed lncRNAs, 771 were downregulated and 545 were upregulated. Results of the qRT-PCR were consistent with the microarray data. lncRNA ENST00000452391.1, uc001vji.1, and uc021zxw.1 were significantly differentially expressed between sepsis patients and healthy volunteers. Moreover, lncRNA ENST00000504301.1 and ENST00000452391.1 were significantly differentially expressed between sepsis survivors and nonsurvivors. The lncRNA expression profile in the peripheral blood of sepsis patients significantly differed from that of healthy volunteers. Circulating lncRNAs may be good candidates for sepsis biomarkers.

    New definitions of sepsis and septic shock were published in early 2016, updating old definitions that have not been revisited since 2001. These new definitions should profoundly affect sepsis research. In addition, these papers present clinical criteria for identifying infected patients who are highly likely to have or to develop sepsis or septic shock. In contrast to previous approaches, these new clinical criteria are evidence based. In this review, two of the authors of the new definitions detail the content of the papers and explore the implications for shock and sepsis researchers.

    The Global Sepsis Initiative recommends prevention of sepsis through immunizations, vitamins, breast feeding, and other important interventions. In our study, we consider a second set of proposals for preventing intensive care admissions for sepsis in tropical Africa, which have been specifically designed to further prevent ICU admissions for sepsis in the group A nation hospital setting. To reduce admissions with severe sepsis in an ICU of a group A nation through the identification of challenges leading to preventable, foreseeable, or nosocomial sepsis specific to our setting. Malawi is one of the poorest countries in the world. Lacking the ability to comply with standard sepsis treatment, we conducted over 4 years several studies, audits, and surveys to identify challenges leading to preventable pediatric sepsis in our setting. We developed a method to identify malnourished children through a "gatekeeper" in the theaters without any equipment, tried to implement the World Health Organization's Safe Surgery Campaign checklist, evaluated our educational courses for the districts to improve the quality of referrals, looked into the extreme fasting times discovered in our hospital, trained different cadres in the districts to deal with peripartal and posttraumatic sepsis, and identified the needs in human resources to deal with pediatric sepsis in our setting. Six foci were identified as promising to work on in future. Focus 1: Preventing elective operations and procedures in malnourished children in the hospital and in the district: 134 of 145 nurses (92.4%) and even 25 of 31 African laymen (80.6%) were able to identify malnourished children with their own fingers. Focus 2: Preventing sepsis-related problems in emergencies through the implementation of the Safe Surgery Campaign checklist: only 100 of 689 forms (14.5%) were filled in due to challenges in ownership, communication responsibility, and time constraints.

    Thrombopoietin (TPO), a growth factor primarily involved in regulating thrombopoiesis, has been recently implicated in the pathogenesis of sepsis. TPO levels are, indeed, greatly increased in patients with sepsis compared to control subjects, and correlate with sepsis severity. The aim of this study was to evaluate TPO as predictive biomarker of sepsis and of sepsis severity in patients entering the emergency department (ED) with systemic inflammatory response syndrome (SIRS). This was a prospective observational study. Ours is a sub-study of the 'Need-speed trial', a multi-center observational study involving six Italian centers affiliated to the GREAT Italian Network. TPO was measured by ELISA. We enrolled 13 patients with SIRS (6 with acute pancreatitis, 3 with acute heart failure, 1 with pulmonary embolism, and 3 with allergic reactions), and 40 patients with sepsis, eight of whom had severe sepsis and three septic shock. TPO was significantly higher in patients with sepsis than with SIRS. In addition, TPO was higher in patients with severe sepsis than with sepsis, and in patients with septic shock than with severe sepsis, although these differences did not reach the statistical significance. Our preliminary results suggest that TPO may have the potential to be considered a promising early biomarker for both the diagnosis of sepsis and the assessment of sepsis severity in patients with SIRS entering the ED.

    Thrombopoietin (TPO) is a humoral growth factor that does not induce platelet aggregation per se, but enhances platelet activation in response to several agonists. Circulating levels of TPO are increased in patients with sepsis and are mainly related to sepsis severity. To investigate the potential contribution of elevated TPO levels in platelet activation during burn injury complicated or not by sepsis. We studied 22 burned patients, 10 without and 12 with sepsis, and 10 healthy subjects. We measured plasma levels of TPO, as well as leukocyte-platelet binding and P-selectin expression. The priming activity of plasma from burned patients or healthy subjects on platelet aggregation and leukocyte-platelet binding, and the role of TPO in these effects were also studied in vitro. Burned patients without and with sepsis showed higher circulating TPO levels and increased monocyte-platelet binding compared with healthy subjects. Moreover, TPO levels, monocyte-platelet binding and P-selectin expression were significantly higher in burned patients with sepsis than in burned patients without sepsis. In vitro, plasma from burned patients without and with sepsis, but not from healthy subjects, primed platelet aggregation, monocyte-platelet binding and platelet P-selectin expression. The effect of plasma from burned patients with sepsis was significantly higher than that of plasma from burned patients without sepsis. An inhibitor of TPO prevented the priming effect of plasma from burned patients. Increased TPO levels may enhance platelet activation during burn injury and sepsis, potentially participating in the pathogenesis of multi-organ failure in these diseases.

    Sepsis kills almost 5,000 children annually, accounting for 16% of pediatric health care spending in the United States. We sought to identify sepsis within the Electronic Health Record (EHR) of a quaternary children's hospital to characterize disease incidence, improve recognition and response, and track performance metrics. Methods are organized in a plan-do-study-act cycle. During the "plan" phase, electronic definitions of sepsis (blood culture and antibiotic within 24 hours) and septic shock (sepsis plus vasoactive medication) were created to establish benchmark data and track progress with statistical process control. The performance of a screening tool was evaluated in the emergency department. During the "do" phase, a novel inpatient workflow is being piloted, which involves regular sepsis screening by nurses using the tool, and a regimented response to high risk patients. Screening tool use in the emergency department reduced time to antibiotics (Fig. 1). Of the 6,159 admissions, EHR definitions identified 1,433 (23.3%) between July and December 2016 with sepsis, of which 159 (11.1%) had septic shock. Hospital mortality for all sepsis patients was 2.2% and 15.7% for septic shock (Table 1). These findings approximate epidemiologic studies of sepsis and severe sepsis, which report a prevalence range of 0.45-8.2% and mortality range of 8.2-25% (Table 2). 1-5 . Implementation of a sepsis screening tool is associated with improved performance. The prevalence of sepsis conditions identified with electronic definitions approximates the epidemiologic landscape characterized by other point-prevalence and administrative studies, providing face validity to this approach, and proving useful for tracking performance improvement.

    This study was aimed to investigate the role of erythrocyte, platelet and reticulocyte (RET) parameters, measured by new haematological analyser Sysmex XN and C reactive protein (CRP), for early diagnosis of sepsis during intensive care unit (ICU) stay. The study population consisted of 62 ICU patients, 21 of whom developed sepsis during ICU stay and 41 who did not. The performance for early diagnosing of sepsis was calculated as area under the curve (AUC) of receiver operating characteristics curves analysis. Compared with CRP (AUC 0.81), immature platelet fraction (IPF) (AUC 0.82) showed comparable efficiency for identifying the onset of sepsis. The association with the risk of developing sepsis during ICU stay was also assessed. One day before the onset of sepsis, a decreased of RET% was significantly associated with the risk of developing sepsis (OR=0.35, 95% CI 0.14 to 0.87), whereas an increased of IPF absolute value (IPF#) was significantly associated with the risk of developing sepsis (OR=1.13, 95% CI 1.03 to 1.24) 2 days before the onset of sepsis. The value of CRP was not predictive of sepsis at either time points. IPF# and RET% may provide valuable clinical information for predicting the risk of developing sepsis, thus allowing early management of patients before the onset of clinically evident systemic infections. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Microvascular dysfunction plays a key role in the pathology of sepsis, leading to multi-organ failure, and death. Circulating endothelial progenitor cells (cEPCs) are critically involved in the maintenance of the vascular homeostasis in both physiological and pathological contexts. In this study, concentration of cEPCs in preterm infants with sepsis was determined to recognize whether the EPC mobilization would affect the clinical outcome of infantile sepsis. One hundred and thirty-three preterm infants (81 with sepsis and 52 without sepsis) were enrolled in this study. The release of EPCs in circulation was first quantified. Thereafter, these cells were cultivated and biological features of these cells such as, proliferation and colony forming efficiency were analyzed. The levels of chemoattractant cytokines were also measured in infants. In mouse models of sepsis, effects of VEGF and SDF-1 as well as anti-VEGF and anti-SDF-1 were evaluated in order to shed light upon the role which the EPC mobilization plays in the overall survival of septic animals. Circulating EPCs were significantly higher in preterm infants with sepsis than in the non-sepsis group. Serum levels of VEGF, SDF-1, and Angiopoietin-2 were also higher in preterm infants with sepsis than in control non-sepsis. In the animal experiments, injection of VEGF and SDF-1 prompted the mobilization of EPCs, leading to an improvement in survival whereas injection of anti-VEGF and anti-SDF-1 was associated with significant deterioration of survival. Overall, our results demonstrated the beneficial effects of EPC release in preterm infants with sepsis, with increased mobilization of these cells was associated with improved survival. J. Cell.

    To evaluate the association between stent dwelling time and sepsis after ureteroscopy, and identify risk factors for sepsis in this setting. The prospectively collected database of a single institution was queried for all patients who underwent ureteroscopy for stone extraction between 2010 and 2016. Demographic, clinical, preoperative and operative data were collected. The primary study endpoint was sepsis within 48 h of ureteroscopy. Logistic regressions were performed to identify predictors of post-ureteroscopy sepsis in the ureteroscopy cohort and specifically in patients with prior stent insertion. Between October 2010 and April 2016, 1 256 patients underwent ureteroscopy for stone extraction. Risk factors for sepsis included prior stent placement, female gender and Charlson comorbidity index. A total of 601 patients had a ureteric stent inserted before the operation and were included in the study cohort, in which the median age was 56 years, 90 patients were women (30%), and 97 patients were treated for positive preoperative urine cultures (16.1%). Postoperative sepsis, Sepsis rates after stent dwelling times of 1, 2, 3 and >3 months were 1, 4.9, 5.5 and 9.2%, respectively. On multivariate analysis, stent dwelling time, stent insertion because of sepsis, and female gender were significantly associated with post-ureteroscopy sepsis in patients with prior stent placement. Patients who undergo ureteroscopy after ureteric stent insertion have a higher risk of postoperative sepsis. Prolonged stent dwelling time, sepsis as an indication for stent insertion, and female gender are independent risk factors. Stent placement should be considered cautiously, and if inserted, ureteroscopy should be performed within 1 month. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    Premature infants can experience cardiorespiratory events such as apnea after immunization in the neonatal intensive care unit (NICU). These changes in clinical status may precipitate sepsis evaluations. This study evaluated whether sepsis evaluations are increased after immunizations in the NICU. We conducted a retrospective cohort study of infants older than 53 days who were vaccinated in the NICU at the KPMCP (Kaiser Permanente Medical Care Program). Chart reviews were carried out before and after all immunizations were administered and for all sepsis evaluations after age 53 days. The clinical characteristics of infants on the day before receiving a sepsis evaluation were compared between children undergoing post-immunization sepsis evaluations and children undergoing sepsis evaluation at other times. The incidence rate of sepsis evaluations in the post-immunization period was compared with the rate in a control time period not following immunization using Poisson regression. A total of 490 infants met the inclusion criteria. The rate of fever was increased in the 24 h period after vaccination (2.3%, Pimmunization than during the control period, although this was not statistically significant (P=0.09). Infants undergoing a sepsis evaluation after immunization were more likely to have an apneic, bradycardic or moderate-to-severe cardiorespiratory event in the day before the evaluation than were infants undergoing sepsis evaluations at other times (Pimmunization in the NICU, routine vaccination was not associated with increased risk of receiving sepsis evaluations. Providers may be deferring immunizations until infants are clinically stable, or may have a higher threshold for initiating sepsis evaluations after immunization than at other times.

  3. Ensemble models of neutrophil trafficking in severe sepsis.

    Directory of Open Access Journals (Sweden)

    Sang Ok Song

    Full Text Available A hallmark of severe sepsis is systemic inflammation which activates leukocytes and can result in their misdirection. This leads to both impaired migration to the locus of infection and increased infiltration into healthy tissues. In order to better understand the pathophysiologic mechanisms involved, we developed a coarse-grained phenomenological model of the acute inflammatory response in CLP (cecal ligation and puncture-induced sepsis in rats. This model incorporates distinct neutrophil kinetic responses to the inflammatory stimulus and the dynamic interactions between components of a compartmentalized inflammatory response. Ensembles of model parameter sets consistent with experimental observations were statistically generated using a Markov-Chain Monte Carlo sampling. Prediction uncertainty in the model states was quantified over the resulting ensemble parameter sets. Forward simulation of the parameter ensembles successfully captured experimental features and predicted that systemically activated circulating neutrophils display impaired migration to the tissue and neutrophil sequestration in the lung, consequently contributing to tissue damage and mortality. Principal component and multiple regression analyses of the parameter ensembles estimated from survivor and non-survivor cohorts provide insight into pathologic mechanisms dictating outcome in sepsis. Furthermore, the model was extended to incorporate hypothetical mechanisms by which immune modulation using extracorporeal blood purification results in improved outcome in septic rats. Simulations identified a sub-population (about 18% of the treated population that benefited from blood purification. Survivors displayed enhanced neutrophil migration to tissue and reduced sequestration of lung neutrophils, contributing to improved outcome. The model ensemble presented herein provides a platform for generating and testing hypotheses in silico, as well as motivating further experimental

    New strategies need to be developed for the early recognition and rapid response for the management of sepsis. To achieve this purpose, the Multidisciplinary Sepsis Team (MST) developed the Computerised Sepsis Protocol Management (PIMIS). The aim of this study was to evaluate the convenience of using PIMIS, as well as the activity of the MST. An analysis was performed on the data collected from solicited MST consultations (direct activation of PIMIS by attending physician or telephone request) and unsolicited ones (by referral from the microbiology laboratory or an automatic referral via the hospital vital signs recording software [SIDCV]), as well as the hospital department, source of infection, treatment recommendation, and acceptance of this. Of the 1,581 first consultations, 65.1% were solicited consultations (84.1% activation of PIMIS and 15.9% by telephone). The majority of unsolicited consultations were generated by the microbiology laboratory (95.2%), and 4.8% from the SIDCV. Referral from solicited consultations were generated sooner (5.63days vs 8.47days; P<.001) and came from clinical specialties rather than from the surgical ward (73.0% vs 39.1%; P<.001). A recommendation was made for antimicrobial prescription change in 32% of first consultations. The treating physician accepted 78.1% of recommendations. The high rate of solicited consultations and acceptance of recommended prescription changes suggest that a MST is seen as a helpful resource, and that PIMIS software is perceived to be useful and convenient to use, as it is the main source of referral.

    Intra-abdominal infections are a common problem for the general surgeon and major sources of morbidity and mortality in the intensive care unit. Some of these patients present with peritonitis that can rapidly progress to septic shock. The basic principles of care include prompt resuscitation, antibiotics, and source control. This article will use a detailed case study to outline the management of a patient with severe intra-abdominal infection from diverticulitis from initial resuscitation to reconstruction. Components of the Surviving Sepsis Campaign as they pertain to surgical patients are discussed and updated, and the concept of damage control general surgery is applied. Copyright © 2012.

    Full Text Available Pyomyoma, also known as suppurative leiomyoma, is a rare clinical complication that occurs when a leiomyoma undergoes infarction and subsequent infection. A high index of suspicion is required to make the diagnosis and can be guided by a classic triad of symptoms that includes abdominal pain, sepsis without an obvious source, and a history of leiomyoma. In the vast majority of these cases, total abdominal hysterectomy is required to avoid severe morbidity and potential mortality. We present an unusual case of a postpartum pyomyoma that was successfully treated without the need for hysterectomy. With strong clinical suspicion, early diagnosis, and appropriate management, some affected patients may preserve fertility.

    Sepsis is a major cause of morbidity and mortality, especially at the extremes of age. To understand the human age-specific transcriptomic response to sepsis, a multi-cohort, pooled analysis was conducted on adults, children, infants, and neonates with and without sepsis. Nine public whole-blood gene expression datasets (636 patients) were employed. Age impacted the transcriptomic host response to sepsis. Gene expression from septic neonates and adults was more dissimilar whereas infants and children were more similar. Neonates showed reductions in inflammatory recognition and signaling pathways compared to all other age groups. Likewise, adults demonstrated decreased pathogen sensing, inflammation, and myeloid cell function, as compared to children. This may help to explain the increased incidence of sepsis-related organ failure and death in adults. The number of dysregulated genes in septic patients was proportional to age and significantly differed among septic adults, children, infants, and neonates. Overall, children manifested a greater transcriptomic intensity to sepsis as compared to the other age groups. The transcriptomic magnitude for adults and neonates was dramatically reduced as compared to children and infants. These findings suggest that the transcriptomic response to sepsis is age-dependent, and diagnostic and therapeutic efforts to identify and treat sepsis will have to consider age as an important variable.

    Sepsis is commonly associated with enhanced generation of reactive oxygen metabolites, leading to multiple organ dysfunctions. The aim of this study was to examine the putative protective role of estradiol against sepsis-induced oxidative organ damage. Sepsis was induced by cecal ligation and puncture method in Wistar albino rats. Sham-operated (control) and sepsis groups received saline or estradiol propionate (10 mg/kg) intraperitoneally immediately after the operation and at 12 h. Twenty-four hours after the surgery, rats were decapitated and malondialdehyde, glutathione levels, and myeloperoxidase activity were determined in the liver and ileum, while oxidant-induced tissue fibrosis was determined by collagen contents. Tissues were also examined microscopically. Serum aspartate aminotransferase, alanine aminotransferase levels, and lactate dehydrogenase were measured for the evaluation of liver functions and tissue damage, respectively. Tumor necrosis factor-alpha was also assayed in serum samples. In the saline-treated sepsis group, glutathione levels were decreased significantly, while the malondialdehyde levels, myeloperoxidase activity, and collagen content were increased in the tissues (P Liver function tests and tumor necrosis factor-alpha levels, which were increased significantly (P < 0.001) following sepsis, were decreased (P < 0.05 to P < 0.001) with estradiol treatment. The results demonstrate the role of oxidative mechanisms in sepsis-induced tissue damage, and estradiol, by its antioxidant properties, ameliorates oxidative organ injury, implicating that treatment with estrogens might be applicable in clinical situations to ameliorate multiple organ damage induced by sepsis.

    Sepsis is a major worldwide cause of morbidity and mortality. Most sepsis epidemiologic data are from the Western literature. Sparse data from India describe the epidemiology of infection rather than sepsis which is a host response to infection. This study describes the epidemiology of sepsis in the Intensive Care Unit (ICU) of an Indian tertiary care hospital. A prospective study conducted between June 2006 and May 2011. All consecutively admitted patients during the 5 year study >=18 years of age were included and data obtained from hospital in-patient records. Variables measured were the incidence of severe sepsis, ICU, hospital, and 28-day mortality, the median length of ICU stay, median Acute Physiology and Chronic Health Evaluation II (APACHE II) score, infection site, and microbial profile. There were 4711 admissions during the study with 282 (6.2%, 95% confidence interval 2.3, 13.1) admissions with severe sepsis. ICU mortality, hospital mortality, and 28-day mortality were 56%, 63.6%, and 62.8%, respectively. Predominant infection site was respiratory tract. The most common organisms were Gram-negative microbes. The most common microbe was Acinetobacter baumanni. Median APACHE II score on admission was 22 (interquartile range 16-28) and median length of ICU stay was 8 days. Severe sepsis attributable mortality was 85%. Severe sepsis is common in Indian ICUs and is mainly due to Gram-negative organisms. ICU mortality is high in this group and care is resource intensive due to increased length of stay.

    Sepsis represents a global health problem in terms of morbidity, mortality, social and economic costs. Although usually managed in Intensive Care Units, sepsis showed an increased prevalence among Internal Medicine wards in the last decade. This is substantially due to the ageing of population and to multi-morbidity. These characteristics represent both a risk factor for sepsis and a relative contra-indication for the admission to Intensive Care Units. Although there is a lack of literature on the management of sepsis in Internal Medicine, the outcome of these patients seems to be gradually improving. This is due to Internists' increased adherence to guidelines and "bundles". The routine use of SOFA score helps physicians in the definition of septic patients, even if the optimal score has still to come. Point-of-care ultrasonography, lactates, procalcitonin and beta-d-glucan are of help for treatment optimization. The purpose of this narrative review is to focus on the management of sepsis in Internal Medicine departments, particularly on crucial concepts regarding diagnosis, risk assessment and treatment. Key Messages Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. The prevalence of sepsis is constantly increasing, affecting more hospital patients than any other disease. At least half of patients affected by sepsis are admitted to Internal Medicine wards. Adherence to guidelines, routine use of clinical and lab scores and point-of-care ultrasonography are of help for early recognition of septic patients and treatment optimization.

DESIGN SETTING AND PARTICIPANTS: Retrospective cohort study from 646,988 patient discharges with severe sepsis from 3,487 hospitals in the Nationwide Inpatient Sample from 2002 to 2011. EXPOSURES: The exposure of interest was the mean yearly sepsis case volume per hospital divided into tertiles. MAIN OUTCOMES AND MEASURES: Inpatient mortality. RESULTS: Compared with the highest tertile of severe sepsis volume (>60 cases per year, the odds ratio for inpatient mortality among persons admitted to hospitals in the lowest tertile (≤10 severe sepsis cases per year was 1.188 (95% CI: 1.074-1.315, while the odds ratio was 1.090 (95% CI: 1.031-1.152 for patients admitted to hospitals in the middle tertile. Similarly, improved survival was seen across the tertiles with an adjusted inpatient mortality incidence of 35.81 (95% CI: 33.64-38.03 for hospitals with the lowest volume of severe sepsis cases and a drop to 32.07 (95% CI: 31.51-32.64 for hospitals with the highest volume. CONCLUSIONS AND RELEVANCE: We demonstrate an association between a higher severe sepsis case volume and decreased mortality. The need for a systems-based approach for improved outcomes may require a high volume of severely septic patients.

    To compute the financial and mortality impact of InSight, an algorithm-driven biomarker, which forecasts the onset of sepsis with minimal use of electronic health record data. This study compares InSight with existing sepsis screening tools and computes the differential life and cost savings associated with its use in the inpatient setting. To do so, mortality reduction is obtained from an increase in the number of sepsis cases correctly identified by InSight. Early sepsis detection by InSight is also associated with a reduction in length-of-stay, from which cost savings are directly computed. InSight identifies more true positive cases of severe sepsis, with fewer false alarms, than comparable methods. For an individual ICU with 50 beds, for example, it is determined that InSight annually saves 75 additional lives and reduces sepsis-related costs by $560,000. InSight performance results are derived from analysis of a single-center cohort. Mortality reduction results rely on a simplified use case, which fixes prediction times at 0, 1, and 2 h before sepsis onset, likely leading to under-estimates of lives saved. The corresponding cost reduction numbers are based on national averages for daily patient length-of-stay cost. InSight has the potential to reduce sepsis-related deaths and to lead to substantial cost savings for healthcare facilities.

    Full Text Available Sepsis is the leading cause of death in intensive care units in the US, and it is known that chronic alcohol use is associated with higher incidence of sepsis, longer ICU stays, and higher mortality from sepsis. Both sepsis and chronic alcohol use are associated with immune deficits such as decreased lymphocyte numbers, impaired innate immunity, delayed-type hypersensitivity reactions, and susceptibility to infections; however, understanding of specific pathways of interaction or synergy between these two states of immune dysregulation is lacking. This study therefore sought to elucidate mechanisms underlying the immune dysregulation observed during sepsis in the setting of chronic alcohol exposure. Using a murine model of chronic ethanol ingestion followed by sepsis induction via cecal ligation and puncture, we determined that while CD4+ and CD8+ T cells isolated from alcohol fed mice eventually expressed the same cellular activation markers (CD44, CD69, and CD43 and effector molecules (IFN-γ, TNF as their water fed counterparts, there was an overall delay in the acquisition of these phenotypes. This early lag in T cell activation was associated with significantly reduced IL-2 production at a later timepoint in both the CD4+ and CD8+ T cell compartments in alcohol sepsis, as well as with a reduced accumulation of CD8dim activated effectors. Taken together, these data suggest that delayed T cell activation may result in qualitative differences in the immune response to sepsis in the setting of chronic alcohol ingestion.

    A system to provide surveillance, diagnosis, and protocolized management of surgical intensive care unit (SICU) sepsis was undertaken as a performance improvement project. A system for sepsis management was implemented for SICU patients using paper followed by a computerized system. The hypothesis was that the computerized system would be associated with improved process and outcomes. A system was designed to provide early recognition and guide patient-specific management of sepsis including (1) modified early warning signs-sepsis recognition score (MEWS-SRS; summative point score of ranges of vital signs, mental status, white blood cell count; after every 4 hours) by bedside nurse; (2) suspected site assessment (vascular access, lung, abdomen, urinary tract, soft tissue, other) at bedside by physician or extender; (3) sepsis management protocol (replicable, point-of-care decisions) at bedside by nurse, physician, and extender. The system was implemented first using paper and then a computerized system. Sepsis severity was defined using standard criteria. In January to May 2012, a paper system was used to manage 77 consecutive sepsis encounters (3.9 ± 0.5 cases per week) in 65 patients (77% male; age, 53 ± 2 years). In June to December 2012, a computerized system was used to manage 132 consecutive sepsis encounters (4.4 ± 0.4 cases per week) in 119 patients (63% male; age, 58 ± 2 years). MEWS-SRS elicited 683 site assessments, and 201 had sepsis diagnosis and protocol management. The predominant site of infection was abdomen (paper, 58%; computer, 53%). Recognition of early sepsis tended to occur more using the computerized system (paper, 23%; computer, 35%). Hospital mortality rate for surgical ICU sepsis (paper, 20%; computer, 14%) was less with the computerized system. A computerized sepsis management system improves care process and outcome. Early sepsis is recognized and managed with greater frequency compared with severe sepsis or septic shock. The system

    The detection of musculoskeletal sepsis, especially following joint replacement, continues to be a challenging problem. Often, even with invasive diagnostic evaluation, the diagnosis of infection remains uncertain. This is a report on the first 55 Indium-111 white blood cell (WBC) images performed in 39 patients for the evaluation of musculoskeletal sepsis. There were 40 negative and 15 positive Indium-111 WBC images. These were correlated with operative culture and tissue pathology, aspiration culture, and clinical findings. Thirty-eight images were performed for the evaluation of possible total joint sepsis (8 positive and 30 negative images); 17 for the evaluation of nonarthroplasty-related musculoskeletal sepsis (7 positive and 10 negative images). Overall, there were 13 true-positive, 39 true-negative, two false-positive, and one false-negative images. Indium-111 WBC imaging is a sensitive and specific means of evaluating musculoskeletal sepsis, especially following total joint replacement

    Full Text Available Background/Aims: Pediatric sepsis is a disease that threatens life of children. The incidence of pediatric sepsis is higher in developing countries due to various reasons, such as insufficient immunization and nutrition, water and air pollution, etc. Exploring the potential genes via different methods is of significance for the prevention and treatment of pediatric sepsis. This study aimed to identify potential genes associated with pediatric sepsis utilizing analysis of gene network and entropy. Methods: The mRNA expression in the blood samples collected from 20 septic children and 30 healthy controls was quantified by using Affymetrix HG-U133A microarray. Two condition-specific protein-protein interaction networks (PINs, one for the healthy control and the other one for the children with sepsis, were deduced by combining the fundamental human PINs with gene expression profiles in the two phenotypes. Subsequently, distinct modules from the two conditional networks were extracted by adopting a maximal clique-merging approach. Delta entropy (ΔS was calculated between sepsis and control modules. Results: Then, key genes displaying changes in gene composition were identified by matching the control and sepsis modules. Two objective modules were obtained, in which ribosomal protein RPL4 and RPL9 as well as TOP2A were probably considered as the key genes differentiating sepsis from healthy controls. Conclusion: According to previous reports and this work, TOP2A is the potential gene therapy target for pediatric sepsis. The relationship between pediatric sepsis and RPL4 and RPL9 needs further investigation.

    Recent studies indicate that death certificate-based single-cause-of-death diagnoses can substantially underestimate the contribution of sepsis to mortality in the general population and among maternal decedents. There are no population-based data in the United States on the patterns of the contribution of sepsis to pregnancy-associated deaths. We studied the Texas Inpatient Public Use Data File to identify pregnancy-associated hospitalizations with reported hospital death during 2001-2010. We then examined the annual reporting of sepsis, and that of other reported most common causes of maternal death, including hemorrhage, embolism, preeclampsia/eclampsia, cardiovascular conditions, cardiomyopathy, cerebrovascular accidents, and anesthesia complications. The annual rate of sepsis among decedents, its trend over time, and changes of its annual rank among other examined potential causes of maternal death were assessed. There were 557 pregnancy-associated hospital deaths during study period. Sepsis was reported in 131 (23.5%) decedents. Sepsis has been increasingly reported among decedents, rising by 9.1%/year (P = 0.0025). The rank of sepsis, as compared to the other examined potential causes of maternal death rose from the 5th in 2001 to 1st since 2008. At the end of the last decade, sepsis has been reported in 28.1% of pregnancy-associated deaths. More than one potential cause of maternal death was reported in 39% of decedents. Sepsis has become the most commonly reported potential cause of death among maternal decedents in the present cohort, noted in over 1 in 4 fatal hospitalizations by the end of the last decade. Although causality cannot be inferred from administrative data, given its known contribution to maternal death, it is likely that sepsis plays an increasing role in fatal maternal hospital outcomes. The prevalent co-reporting of multiple potential causes of maternal death in the present cohort underscores the complexity of determining the sources of

    Despite advances in neonatal care, sepsis remains a major cause of morbidity and mortality in neonates worldwide. Pathway cross-talk analysis might contribute to the inference of the driving forces in bacterial sepsis and facilitate a better understanding of underlying pathogenesis of neonatal sepsis. This study aimed to explore the critical pathways associated with the progression of neonatal sepsis by the pathway cross-talk analysis. By integrating neonatal transcriptome data with known pathway data and protein-protein interaction data, we systematically uncovered the disease pathway cross-talks and constructed a disease pathway cross-talk network for neonatal sepsis. Then, attract method was employed to explore the dysregulated pathways associated with neonatal sepsis. To determine the critical pathways in neonatal sepsis, rank product (RP) algorithm, centrality analysis and impact factor (IF) were introduced sequentially, which synthetically considered the differential expression of genes and pathways, pathways cross-talks and pathway parameters in the network. The dysregulated pathways with the highest IF values as well as RPpathways in neonatal sepsis. By integrating three kinds of data, only 6919 common genes were included to perform the pathway cross-talk analysis. By statistic analysis, a total of 1249 significant pathway cross-talks were selected to construct the pathway cross-talk network. Moreover, 47 dys-regulated pathways were identified via attract method, 20 pathways were identified under RPpathways with the highest IF were also screened from the pathway cross-talk network. Among them, we selected 8 common pathways, i.e. critical pathways. In this study, we systematically tracked 8 critical pathways involved in neonatal sepsis by integrating attract method and pathway cross-talk network. These pathways might be responsible for the host response in infection, and of great value for advancing diagnosis and therapy of neonatal sepsis. Copyright © 2017

    Sepsis, severe sepsis and septic shock are among the most common conditions handled in the emergency department (ED). According to new Sepsis Guidelines, early diagnosis and treatment are the keys to improve survival. Plasma C-reactive protein (CRP) and procalcitonin (PCT) levels, when associated with documented or suspected infection, are now part of the definitions of sepsis. Blood culture is the gold standard method for detecting microorganisms but it requires too much time for results to be known. Sensitive biomarkers are required for early diagnosis and as indexes of prognosis sepsis. CRP is one of the acute phase proteins synthesized by the liver: it has a great sensitivity but a very poor specificity for bacterial infections. Moreover, the evolution of sepsis does not correlate with CRP plasma changes. In recent years PCT has been widely used for sepsis differential diagnosis, because of its close correlation with infections, but it still retains some limitations and false positivity (such as in multiple trauma and burns). Soluble CD14 subtype (sCD14-ST), also known as presepsin, is a novel and promising biomarker that has been shown to increase significantly in patients with sepsis, in comparison to the healthy population. Studies pointed out the capability of this biomarker for diagnosing sepsis, assessing the severity of the disease and providing a prognostic evaluation of patient outcome. In this mini review we mainly focused on presepsin: we evaluate its diagnostic and prognostic roles in patients presenting to the ED with systemic inflammatory response syndrome (SIRS), suspected sepsis or septic shock.
