Association between serum triglyceride level and severity of acute biliary pancreatitis.

BACKGROUND: Acute biliary pancreatitis (ABP) is the most common type of acute pancreatitis. However, the effect of serum triglyceride (TG) levels on the severity of ABP remains unclear. The aim of this study was to assess the correlation between serum TG levels and the severity of ABP. METHODS: Data from 526 ABP patients was analyzed in this study. The patients were divided into normal and elevated groups according to the TG level measured within 24 h after admission, and the elevated group was further divided into mild, moderate, and severe elevated groups. The demographic data and clinical outcomes of each group were compared. RESULTS: Of the 526 ABP patients, 394 were in the normal TG group and 132 were in the elevated TG group (36 mild, 57 moderate, and 39 severe). The elevated group was younger (51.5 ± 12.9 vs. 58.9 ± 13.9), predominantly male (66.7% vs. 45.2%), had more history of diabetes (22.7% vs. 12.4%) and hyperlipidemia (19.7% vs. 0.8%), and developed systemic inflammatory response syndrome (SIRS) (25.8% vs. 15.5%), persistent organ failure (POF) (11.4% vs. 2.8%), and local complications (62.9% vs. 42.1%) more frequently compared to the normal group (P < 0.05). The incidence of SIRS, POF, acute peripancreatic fluid collection (APFC), and acute necrotic collection (ANC) increased with increasing TG levels (Ptrend < 0.05). In multivariate analysis, TG was independently associated with POF, APFC, and ANC in increments of 100 mg/dl (P < 0.05), and there was a linear relationship between TG levels and POF, APFC, and ANC (non-linear P > 0.05, P overall <0.05). In addition, nonalcoholic fatty liver disease is not a risk factor for POF, ANC, and APFC in ABP patients. CONCLUSIONS: Elevated serum TG levels were independently associated with more severe ABP. The incidence of POF, APFC, and ANC in ABP patients increased with the increase of TG levels, with a linear relationship.

Systemic inflammatory response syndrome in patients with severe fever with thrombocytopenia syndrome: prevalence, characteristics, and impact on prognosis.

BACKGROUND: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging zoonosis with a high fatality rate in China. Previous studies have reported that dysregulated inflammatory response is associated with disease pathogenesis and mortality in patients with SFTS. This investigation aimed to evaluate the prevalence and characteristics of systemic inflammatory response syndrome (SIRS), and its impact on prognosis. METHODS: Data on demographic characteristics, comorbid conditions, clinical manifestations, laboratory parameters, and survival time of patients with SFTS were collected. Patients were divided into the non-SIRS and SIRS groups according to the presence of SIRS, then their clinical data were compared. RESULTS: A total of 290 patients diagnosed with SFTS were retrospectively enrolled, including 126(43.4%) patients with SIRS. Patients in the non-survivor group had more prevalence of SIRS than patients in the survivor group (P < 0.001), and SIRS (adjusted OR 2.885, 95% CI 1.226-6.786; P = 0.005) was shown as an independent risk factor for prognosis of patients with SFTS. Compared with patients without SIRS, patients with SIRS had lower WBC and neutrophils counts, and fibrinogen levels, but higher AST, LDH, amylase, lipase, CK, CK-MB, troponin I, APTT, thrombin time, D-dimer, CRP, IL-6, SAA levels, and viral load. The cumulative survival rate of patients with SIRS was significantly lower than that of patients without SIRS. Patients with SIRS also showed a higher incidence of bacterial or fungal infections than patients without SIRS. CONCLUSIONS: SIRS is highly frequent in patients with SFTS, and it is associated with high mortality.

Prophylactic Intra-abdominal Drainage is Associated With Lower Postoperative Complications in Patients With Crohn's Disease: A Randomized Controlled Trial.

BACKGROUND: Prophylactic intraoperative drains have been shown not superior for patients underwent intestinal surgery. However, for patients with Crohn's disease (CD), this needs further exploration. METHODS: In this pilot study, CD patients were randomly assigned to drain (n = 50) and no-drain (n = 50) groups. The primary endpoint was the rate of postoperative prolonged ileus (PPOI). The secondary endpoints were postoperative abdominal ascites, postoperative systemic inflammatory response syndrome (SIRS) and C-reactive protein (CRP) levels. RESULTS: The incidences of PPOI and postoperative abdominal ascites were significantly lower in the drain group (12% vs 44%; 0% vs 24%, both P < .05). Postoperative SIRS incidence and CRP levels were significantly increased in the no-drain group [36% vs 10%; 54.9 vs 34.3 mg/L, both P < .05]. In multivariate analysis, prophylactic drainage was the independent protective factor for PPOI and postoperative LOS. CONCLUSIONS: Prophylactic drainage may be associated with improved clinical outcomes in CD patients.

Association of systemic inflammatory response index and plaque characteristics with the severity and recurrence of cerebral ischemic events.

AIM: We aimed to investigate the relationship between systemic inflammatory response index (SIRI) and intracranial plaque features, as well as the risk factors related to the severity and recurrence of cerebral ischemic events. METHODS: We enrolled 170 patients with cerebral ischemic events. Baseline demographic characteristics and laboratory indicators were collected from all participants. All patients were assessed by high-resolution magnetic resonance vessel wall imaging for culprit plaque characteristics and intracranial atherosclerotic burden. Outpatient or telephone follow-up were conducted at 1, 3, and 6 months after discharge. RESULTS: SIRI levels were significantly associated with the enhanced plaque number (r = 0.205, p = 0.007), total plaque stenosis score (r = 0.178, p = 0.020), total plaque enhancement score (r = 0.222, p = 0.004), intraplaque hemorrhage (F = 5.630, p = 0.004), and plaque surface irregularity (F = 3.986, p = 0.021). Higher SIRI levels (OR = 1.892), total plaque enhancement score (OR = 1.392), intraplaque hemorrhage (OR = 3.370) and plaque surface irregularity (OR = 2.846) were independent risk factors for moderate-severe stroke, and these variables were significantly positively correlated with NIHSS (P < 0.05 for all). In addition, higher age (HR = 1.063, P = 0.015), higher SIRI levels (HR = 2.003, P < 0.001), and intraplaque hemorrhage (HR = 4.482, P = 0.008) were independently associated with recurrent stroke. CONCLUSIONS: Higher SIRI levels may have adverse effects on the vulnerability and burden of intracranial plaques, and links to the severity and recurrence of ischemic events. Therefore, SIRI may provide important supplementary information for evaluating intracranial plaque stability and risk stratification of patients.

Chronic liver disease is an important risk factor for worse outcomes in acute pancreatitis: a systematic review and meta-analysis.

Chronic liver diseases (CLD) affect 1.5 billion patients worldwide, with dramatically increasing incidence in recent decades. It has been hypothesized that the chronic hyperinflammation associated with CLD may increase the risk of a more severe course of acute pancreatitis (AP). This study aims to investigate the underlying impact of CLD on the outcomes of AP. A systematic search was conducted in Embase, Medline, and Central databases until October 2022. Studies investigating patients with acute pancreatitis and CLD, were included in the meta-analysis. A total of 14,963 articles were screened, of which 36 were eligible to be included. CLD was a risk factor for increased mortality with an odds ratio (OR) of 2.53 (CI 1.30 to 4.93, p = 0.01). Furthermore, renal, cardiac, and respiratory failures were more common in the CLD group, with ORs of 1.92 (CI 1.3 to 2.83, p = 0.01), 2.11 (CI 0.93 to 4.77, p = 0.062) and 1.99 (CI 1.08 to 3.65, p = 0.033), respectively. Moreover, the likelihood of developing Systemic Inflammatory Response Syndrome (SIRS) was significantly higher, with an OR of 1.95 (CI 1.03 to 3.68, p = 0.042). CLD is an important risk factor for worse outcomes in AP pancreatitis, leading to higher mortality and increased rates of local and systemic complications.

Infection, Inflammation, and Poststroke Cognitive Impairment.

BACKGROUND: Infection and inflammation are dementia risk factors in population-based cohorts; however, studies in stroke are scarce. We determined the prevalence of infection after stroke and routinely measured inflammatory biomarkers during hospitalization and their associations with acute and 6-month cognitive impairment. METHODS AND RESULTS: A prospective stroke cohort completed the Oxford Cognitive Screen at ≤2 weeks and 6 months after stroke. Infection, inflammatory markers (C-reactive protein, white cell count, and neutrophil/lymphocyte ratio), and systemic inflammatory response syndrome were ascertained throughout admission with electronic patient records supplemented by hand searches. Associations with acute and 6-month global and domain-specific cognitive impairment were analyzed using multivariable regression, adjusting for demographic/vascular factors and stroke severity. Among 255 patients (mean age, 73.9 [SD, 12.6] years; 46.3% women; mean education, 12.6 [SD, 3.7] years; median National Institutes of Health Stroke Scale score 5 [range, minimum-maximum, 0-30]), infection was present in 90 patients (35.3%) at mean 4.4 (SD, 6.9) days after stroke, consisting predominantly of pneumonia (47/90; 52%) and urinary tract infection (39/90; 43%). Admission white cell count was elevated in 25.1% (n=64; mean, 9.5×109/L [SD, 3.2×109/L]), C-reactive protein in 41.2% (n=105; mean, 27.5 [SD, 50.9 mg/L]), neutrophil/lymphocyte ratio in 55.7% (n=97; mean, 5.5 [SD, 4.5]), and systemic inflammatory response syndrome in 26.6% (n=53 [45.2%] positive during hospitalization). Infection was associated with acute and 6-month poststroke cognitive impairment (P<0.05adj) with stronger associations acutely for severe infection (infection+systemic inflammatory response syndrome; P=0.03adj). Acute language, executive function and attention domain impairments, and 6-month number processing impairment were associated with infection (P<0.05adj). No significant relationships were found for any biomarker and cognitive impairment. CONCLUSIONS: Infection and elevations in routinely measured inflammatory biomarkers are common following stroke; however, only infection is associated with poststroke cognitive impairment, suggesting that increases in these biomarkers may be nonspecific. Infection may present a tractable target for reducing poststroke cognitive impairment.

Acute liver failure with a massive upper GI bleed meeting the criteria of MIS-C.

Multisystem inflammatory syndrome in children (MIS-C) is a known complication of COVID-19. There is still limited knowledge about this condition. Here, we report the case of a previously healthy toddler boy, who presented with acute liver failure and duodenal lesions resulting in severe haematemesis and haemorrhagic shock, requiring intensive care unit care. The patient had persistent transaminitis, a deranged coagulation profile, inflammatory markers were elevated, and laboratory tests were negative for common infectious hepatitis aetiologies as well as COVID-19 Reverse transcription polymerase chain reaction. His COVID-19 antibody was reactive. Upper gastrointestinal endoscopy revealed a Forrest grade III duodenal ulcer. Looking into the constellation of symptoms and laboratory findings a confirmed diagnosis of acute viral hepatitis caused by MIS-C was made. Hence, he was given intravenous methylprednisolone along with intravenous immunoglobulins, after which he improved clinically and transaminitis resolved. The patient was discharged on clinical improvement and was doing fine on follow-up up to 6 months.

Consenso sobre el tratamiento del síndrome inflamatorio multisistémico asociado a COVID-19 / Consensus on treatment of multisystemic inflammatory syndrome associated with COVID-19

La pandemia ocasionada por el nuevo coronavirus (SARS-CoV-2), declarada por la Organización Mundial de la Salud OMS) en marzo de 2020, afecta a un reducido número de pacientes pediátricos, quienes presentan, en su mayoría, compromiso respiratorio leve y evolución favorable. Sin embargo, en niños previamente sanos, comenzó a observarse un aumento de casos definidos como síndrome inflamatorio multisistémico (SIM-C) o similar a Kawasaki (Kawasaki-like) asociado a la enfermedad por el nuevo coronavirus (COVID-19) (KL-C) que evolucionan al shock y requieren internación en la unidad de cuidados intensivos.Los cuadros de SIM-C y los KL-C se caracterizan por fiebre, signos de inflamación, síntomas gastrointestinales y disfunción cardiovascular; las formas graves de presentación tienen mayor incidencia de hipotensión y/o shock. En el laboratorio se observan marcadores de inflamación, hipercoagulabilidad y daño miocárdico. El tratamiento farmacológico de primera línea consiste en la administración de inmunoglobulina por vía intravenosa más ácido acetilsalicílico por vía oral.Se recomienda un abordaje multidisciplinario para un diagnóstico certero y un tratamiento temprano y eficaz para disminuir la morbimortalidad.

The pandemic caused by the SARS-CoV-2 virus declared by the WHO in March 11th 2020, affects a small number of pediatric patients, who mostly present mild respiratory compromise and favorable evolution.However began to be observed in previously healthy children, an increase in cases defined as "Multisystemic Inflammatory Syndrome" (MIS-C) or "Kawasaki-like" post-COVID 19 (KL-C) that evolve to shock and require hospitalization in the Pediatric Intensive Care Unit.MIS-C and KL-C are characterized by fever; signs of inflammation, gastrointestinal symptoms, and cardiovascular dysfunction, associated with sever forms of presentation with higher incidence of hypotension and/or shock. In the laboratory, markers of inflammation, hypercoagulability and myocardial damage are observed. First-line drug treatment consists of intravenous immunoglobulin plus oral acetylsalicylic acid.A multidisciplinary approach is recommended for an accurate diagnosis and an early and effective treatment, in order to reduce morbidity and mortality.

Compromiso cardiovascular en pacientes con síndrome inflamatorio pediátrico multisistémico, asociado a infección por SARS-CoV-2 / Cardiovascular involvement in pediatric patients with SARS-CoV-2 associated to multisystemic inflammatory syndrome

Se caracteriza por presentar compromiso multiorgánico con parámetros inflamatorios elevados y manifestaciones clínicas graves, siendo el corazón el órgano más severamente comprometido. OBJETIVO: Describir las características clínicas y de laboratorio de 23 pacientes con diagnóstico de PIMS con compromiso cardiovascular hospitalizados en un centro único. MÉTODO: Se efectuó un estudio retrospectivo analizando los hallazgos clínicos y de laboratorio junto a las manifestaciones cardiovasculares que presentaron estos pacientes. RESULTADOS: 23/29 pacientes con PIMS (78%) presentaron manifestaciones digestivas y mucocutáneas. Las manifestaciones cardiovasculares fueron: Síndrome Kawasaki y "Kawasaki like" sin compromiso coronario en 15/23 (65%) y con compromiso coronario en 3 (13%). Shock en 9 pacientes (39%), injuria miocárdica- miocarditis en 8 (35%) y derrame pericárdico en 13 (56%). Trastornos del ritmo cardíaco se observaron en 6 pacientes (26%). La terapia más utilizada fue inmunoglobulina y corticoides. 18 /23 requirieron manejo en unidades de intermedio y/o intensivo. Un 70% de los pacientes se recuperó del compromiso cardiovascular antes del alta. CONCLUSIÓN: El compromiso cardiovascular en PIMS es la complicación más frecuente de esta enfermedad, que se acompaña de manifestaciones inmunológicas y hematológicas graves lo que hace necesario un tratamiento multidisciplinario para un mejor manejo de estos pacientes.

INTRODUCTION: Pediatric Multisystemic Inflammatory Syndrome (PIMS) has emerged as a new disease in children, secondary to SARSCoV-2 infection. It is characterized by multi-organ involvement with elevated inflammatory parameters and severe clinical manifestations, the heart being the organ most severely involved. OBJETIVE: to describe the clinical and laboratory characteristics of 23 patients diagnosed with PIMS with cardiovascular involvement hospitalized in a single center. METHOD: We conducted a retrospective study in which we analyzed the clinical and laboratory findings along with the cardiovascular manifestations presented by these patients. Results: 23/29 patients with PIMS and cardiovascular involvement were selected, 78% had digestive and mucocutaneous manifestations. Cardiovascular manifestations consisted of KawasakiKawasaki like syndrome without coronary involvement in 15/23 (65%) and coronary involvement in 3 (13%). Nine patients developed shock (39%), 8 (35%) myocardial injury in and 13 (56%) pericardial effusion.. Heart rhythm disorders were observed in 6 patients (26%). The main therapy was immunoglobulin and corticosteroids. 18 /23 required management in intermediate and/or intensive care unit. 70% of patients recovered from cardiovascular involvement before discharge. CONCLUSION: Cardiovascular involvement in PIMS is the most frequent complication of this disease, but it is associated with severe immunological and hematological manifestations, which makes necessary a multidisciplinary treatment for a better management

Dianas de la respuesta inflamatoria sistémica desde nuevas perspectivas / Targets of the systemic inflammatory response from new perspectives

Introducción: Existen enfermedades que tienen en su sustento, la respuesta inflamatoria,¿es posible identificar la diana que enmarca el efecto deletéreo de la respuesta inflamatoria? Objetivo: Analizar las expresiones de la respuesta inflamatoria sistémica y sus consecuencias en la morbilidad y mortalidad. Métodos: Se realizó una búsqueda, fundamentalmente en SciELO, con las palabras clave: respuesta inflamatoria sistémica, daño múltiple de órganos, respuesta inflamatoria y sus combinaciones; en idioma español. Se presenta una revisión narrativa a partir del análisis de los documentos obtenidos. Desarrollo: Los mecanismos defensivos de manera no controlada, producen autoagresión del endotelio vascular. La respuesta se acompaña de fallo inmunológico sistémico y disreactividad en la respuesta inflamatoria. La lesión del endotelio vascular, el incremento del consumo de oxígeno, citocinas elevadas en la circulación, activación de la cascada de coagulación y mediadores vasoactivos tienen influencia en esta respuesta. La isquemia intestinal, secundaria al síndrome compartimental abdominal, es causante directa de la translocación bacteriana. La inflamación persistente, asociada a un intenso proceso catabólico conduce a la caquexia y la inmunosupresión. Conclusión: Son múltiples las dianas que se activan en la respuesta inflamatoria sistémica, que explican su disbalance: la disfunción del endotelio vascular y la microcirculación, la disfunción mitocondrial y el estrés oxidativo, la citoprotección celular. Puede haber un punto de convergencia en la necesidad del diagnóstico temprano de esta respuesta disreactiva y en su intento de modulación oportuna(AU)

Introduction: There are diseases that have in their basics, the inflammatory response, is it possible to identify the target that frames the deleterious effect of the inflammatory response? Objective: To analyze the manifestations of the systemic inflammatory response and its consequences in morbidity and mortality. Methods: A search was performed, mainly in SciElo, with the key words: systemic inflammatory response, multiple organ damage, inflammatory response and their combinations; in Spanish language. A narrative review is presented based on the analysis of the documents obtained. Body: The defensive mechanisms in an uncontrolled way, produce self-aggression of the vascular endothelium. The response is accompanied by systemic immune failure and reactivity problems in the inflammatory response. Vascular endothelial injury, increased oxygen consumption, elevated cytokines in the circulation, activation of the coagulation cascade and vasoactive mediators have an influence on this response. Intestinal ischemia, secondary to abdominal compartment syndrome, is a direct cause of bacterial translocation. Persistent inflammation, associated with an intense catabolic process, leads to cachexia and immunosuppression. Conclusion: There are multiple targets that are activated in the systemic inflammatory response, which explain their imbalance: vascular endothelial dysfunction and microcirculation, mitochondrial dysfunction and oxidative stress, cell cytoprotection. There may be a point of convergence in the need for early diagnosis of this dis-reactive response and in its attempt at timely modulation(AU)

Síndrome de respuesta inflamatoria sistémica como indicador pronóstico en pacientes cirróticos hospitalizados / Systemic inflammatory response syndrome as prognostic indicator in hospitalized cirrhotic patients

Objetivo: La inflamación sistémica empeora los trastornos circulatorios en el paciente cirrótico y recientemente el síndrome de respuesta inflamatoria sistémica (SRIS) podría ser un indicador pronóstico en ellos. El objetivo del estudio fue determinar si la presencia de SRIS al ingreso en pacientes cirróticos hospitalizados está asociada a complicaciones o mortalidad. Materiales y métodos: Estudio de cohortes retrospectiva, realizado en el Hospital Nacional Daniel Alcides Carrión. Se admitieron pacientes cirróticos hospitalizados desde julio 2008 hasta diciembre 2010 sin comorbilidades importantes, neoplasia maligna, infección VIH, o estancia fue menor a 72 horas. Se evaluó presencia de SRIS al ingreso y la aparición de complicaciones o muerte después de 72 horas del ingreso. Resultados: Fueron 150 pacientes cirróticos admitidos, se excluyeron 6, tres por supervivencia menor a las 72 horas, uno por neoplasia, uno por insuficiencia cardiaca severa y dos por insuficiencia renal crónica. En total 144 pacientes ingresaron al estudio, 95 (66%) pacientes presentaron SRIS al ingreso. No hubo diferencia significativa en cuanto a edad, sexo, etiología, en ambos grupos. SRIS estuvo asociado a mayores puntajes de MELD y Child-Pugh Turcotte. De los pacientes con SRIS, 41 (43%) se complicaron y 16 (16,8%) fallecieron, mientras que del grupo sin SRIS 5 (10,2%) se complicaron y 2 (4%) fallecieron, (p<0,0001y p=0,028 respectivamente). Las complicaciones más frecuentes fueron las infecciones y encefalopatía hepática. En el análisis multivariado SRIS estuvo asociado a complicaciones (p<0,006) mas no a mortalidad (p<0,276). Conclusiones: SRIS es frecuente en pacientes cirróticos hospitalizados y está asociado a complicaciones intrahospitalarias.

Objective: The systemic inflammation worsens circulatory disorders in cirrhotic patients and recently the systemic inflammatory response syndrome (SIRS) may be a prognostic indicator therein. The aim of the study was to determine whether the presence of SIRS at admission in hospitalized cirrhotic patients is associated with complications or mortality. Materials and methods: A retrospective cohorts study was conducted at the Daniel Alcides Carrion National Hospital. Hospitalized cirrhotic patients admitted from July 2008 to December 2010 without significant comorbidities, malignancy, HIV infection, or stay less than 72 hours were included. Presence of SIRS at admission and the occurrence of complications or death after 72 hours of admission were evaluated. Results: 150 cirrhotic patients were admitted, six were excluded; three for lower survival at 72 hours, one for neoplasia, one for severe heart failure and two for chronic renal failure. One hundred forty four patients were included, 95 (66%) patients had SIRS at admission. There was no significant difference in age, sex, etiology, in both groups. SIRS was associated with higher scores of MELD and Child-Turcotte Pugh. Of the group of patients with SIRS, 41 (43%) had complications and 16 (16.8%) died, while the group without SIRS 5 (10.2%) had complications and two (4%) died (p<0.0001 and p=0.028 respectively). The most common complications were infections and hepatic encephalopathy. In multivariate analysis SIRS was associated with complications (p<0.006) but not with mortality (p<0.276). Conclusions: SIRS is common in hospitalized cirrhotic patients and is associated with in-hospital complications.

Corioamnionitis histológica y morbimortalidad neonatal: aproximación al síndrome de respuesta inflamatoria fetal / Chorioamnionitis neonatal morbidity: approach to fetal inflammatory response syndrome

Antecedentes: El síndrome de respuesta inflamatoria fetal (SRIF) es una entidad relacionada con la presencia de inflamación intrauterina y suele asociarse a infección intraamniótica. Su consecuencia más grave es la lesión cerebral y posterior desarrollo de parálisis cerebral. Objetivo: Evaluar la relación entre el síndrome de respuesta inflamatoria fetal y el desarrollo de complicaciones neonatales. Método: Estudio descriptivo y retrospectivo, realizado en el Hospital Universitario La Paz de Madrid, buscando una aproximación al SRIF desde la corioamnionitis histológica/funiculitis. El grupo de estudio constituido por 35 gestaciones simples pretérmino recogidas durante el primer semestre de 2008 y en las que la anatomía patológica de la placenta y anexos ovulares demostró la presencia de una corioamnionitis histológica y/o funiculitis. Resultados: Siete casos (20 por ciento) presentaban clínica sospechosa de infección intraamniótica, si bien en 28 gestantes (80 por ciento) existían factores de riesgo asociados al síndrome de respuesta inflamatoria fetal. Mortalidad perinatal en el grupo estudiado fue de 11,4 por ciento (4 casos). Sólo en 2 pacientes (5,7 por ciento) se pudo relacionar la muerte con el SRIF. En 28 recién nacidos (80 por ciento) se encontró algún tipo de patología, siendo la misma inherente a dicho síndrome en 17 casos (48,6 por ciento), destacando sepsis neonatal (40 por ciento), leucomalacia periventricular (14,3 por ciento) y displasia broncopulmonar (5,7 por ciento). Conclusión: Se comprueba el alto riesgo neonatal del SRIF. El conocimiento de esta condición, abre una serie de controversias diagnósticas y terapéuticas que obliga a una reevaluación de los protocolos actuales de manejo de la amenaza de parto pretérmino y la rotura prematura de membranas de pretérmino.

Background: The fetal inflammatory response syndrome (FIRS) is an entity related to intrauterine inflammation which is commonly associated with intraamniotic infection. The most serious consequence is the neurologic damage and the subsequent development of cerebral palsy. Aims: To evaluate the relationship between the fetal inflammatory response syndrome and the development of neonatal complications. Method: Descriptive and retrospective study realized in "La Paz" University Hospital of Madrid, looking for an approximation to the FIRS from histologic chorioamnionitis/funisitis. Group of study constituted by 35 single preterm gestations collected during the first semester of 2008 and in which the pathologic anatomy study of the placenta and annexes showed the presence of histological corioamnionitis and / or funisitis. Results: Suspicious clinic was found in 7 cases (20 percent) but in 28 cases (80 percent) risk factors associated to FIRS were present. Perinatal mortality found was 11.4 percent (4 cases). Only in 2 cases (5.7 percent) the cause was relationated with FIRS. Pathology associated was found in 28 newborn (80 percent), being 17 cases (48.6 percent) pathology associated with the fetal inflammatory response syndrome, enhancing neonatal sepsis (40 percent), periventricular leukomalacia (14.3 percent), and bronchopulmonar dysplasia (5.7 percent). Conclusion: It is verified that FIRS enteals a high neonatal risk. The knowledge of this entity opens some diagnostic and therapeutic controversies. Current management protocols of preterm labor and preterm premature rupture of membranes should be revised.

Avaliação do impacto da aplicação de manobra de hiperinsuflação pulmonar sobre a resposta inflamatória sistêmica e colapso pulmonar em pacientes submetidos a procedimentos cirúrgicos sob ventilação espontânea / Assessing the impact of lung hyperinflation maneuver on systemic inflammatory response and lung collapse in patients undergoing surgeries under spontaneous ventilation

JUSTIFICATIVA E OBJETIVOS: O uso de manobras de hiperinsuflação pulmonar (MHP) reverte atelectasias intraoperatórias. Contudo, pode induzir resposta inflamatória sistêmica de origem pulmonar. O objetivo deste estudo foi testar o impacto da aplicação de MHP sobre a resposta inflamatória sistêmica e sobre a estrutura pulmonar em pacientes submetidos à anestesia subaracnoidea. MÉTODO: Após aprovação do Comitê de Ética institucional e obtenção do consentimento escrito pós-informado, 20 pacientes submetidos a procedimentos cirúrgicos de pequeno e médio porte foram alea torizados em dois grupos: 1) Controle (GC) e 2) MHP (GMHP). Uma hora após a instalação do bloqueio espinhal, foi realizada MHP no GMHP aplicando-se pressão positiva nas vias aéreas em dois níveis (BIPAP) com pressão expiratória de 20 cmH2O e pressão inspiratória de 20 cmH2O durante 1 a 2 minutos. TNFα, IL-1, IL-6, IL-8, IL-10 e IL-12 foram medidos no sangue através de técnica de citometria de fluxo nos momentos basal, 90, 180 e 780 minutos. Os volumes e peso pulmonares foram computados a partir de tomografias computadorizadas obtidas imediatamente após a cirurgia. RESULTADOS: A aplicação de MHP resultou em redução da fração de parênquima pulmonar não aerado (7,5 ± 4,3 por cento no Grupo Controle versus 4 ± 2,1 por cento no Grupo MHP, p = 0,02), sem alterações nos volumes pulmonares. Foi observada elevação progressiva nos valores plasmáticos das interleucinas IL-1, IL-6, IL-8 e IL-10, similar nos dois grupos. Os níveis plasmáticos de TNFα e IL-12 foram indetectáveis durante o estudo. CONCLUSÕES: A aplicação de MHP única reduziu a fração de atelectasias, porém não amplificou a resposta inflamatória observada em pacientes com pulmões normais submetidos a cirurgias de pequeno e médio portes sob anestesia subaracnoidea.

BACKGROUND AND OBJECTIVES: Lung hyperinflation maneuvers (LHM) reverse intraoperative atelectasis; however, they can lead to pulmonary-induced systemic inflammatory response. The objective of this study was to determine the impact of LHM on systemic inflammatory response and lung structure in patients undergoing subarachnoid block. METHODS: After approval by the Ethics Committee of the institution and signing the informed consent, 20 patients undergoing small and medium surgical procedures were randomly separated into two groups: 1) control (CG), and 2) LHM (LHMG). One hour after the spinal anesthesia, LHM was performed in LHMG by applying bilevel positive pressure in the airways (BIPAP) with an expiratory pressure of 20 cmH2O and inspiratory pressure of 20 cmH2O for 1 to 2 minutes. Blood levels of TNFα, IL-1, IL-6, IL-8, IL-10, and IL-12 were determined by flow cytometry at baseline and at 90, 180, and 780 minutes. Lung volumes and weights were determined using CT scans obtained immediately after the surgery. RESULTS: The use of LHM resulted in a reduction in the fraction of non-aerated pulmonary parenchyma (7.5 ± 4.3 percent, in the Control Group, vs. 4 ± 2.1 percent, in the LHM Group, p = 0.02) without changing pulmonary volumes. A progressive increase in plasma levels of IL-1, IL-6, IL-8, and IL-10, similar in both groups, was observed. Plasma levels of TNFα and IL-12 were undetectable during the study. CONCLUSIONS: The use of LHM reduced the incidence of atelectasis, but it did not amplify the inflammatory response in patients with normal lungs undergoing small and medium surgeries under subarachnoid block.

Los niveles plasmáticos de FNT< y IL-12 no se detectaron durante el estudio. CONCLUSIONES: La aplicación de MHP única redujo la fracción de atelectasias, sin embargo, no amplificó la respuesta inflamatoria observada en pacientes con pulmones normales sometidos a cirugías de pequeño y mediano porte bajo anestesia subaracnoidea.

Choque cardiogênico: disfunção mecânica e inflamatória / Cardiogenic shock: a mechanical and inflammatory dysfunction

O choque cardiogênico é caracterizado como um estado de hipoperfusão sistêmica secundária a disfunção cardíaca grave. Clinicamente é definido como pressão sistólica abaixo de 90mmHg ou queda da pressão arterial média de 30 mmHg em relação ao basal. Em termos hemodinâmicos, é definido como índice cardíaco menor que 1,8 1/min/m2 sem suporte ou entre 2,0 1/min/m2 e 2,2 1/min/m2 com suporte, além de pressão capilar pulmonar elevada em, pelo menos, 15 mmHg. Sua principal etiologia é o infarto agudo do miocárdio com supradesnivelamento de ST. Estudos recentes tem demonstrado que cerca de 20 por cento dos pacientes com choque cardiogênico evoluem com características clínicas e hemodinâmicas de resposta inflamatória sistêmica caracterizada por febre, leucocitose e diminuição da resistência vascular sistêmica. Neste artigo discutiremos esses aspectos e as implicações dessa apresentação.
