Proceso de enfermería en paciente con choque séptico desde la perspectiva del déficit de autocuidado (caso clínico) / Nursing process in a patient with septic shock from the perspective of self-care deficit

El choque séptico es un estado de hipoperfusión tisular definido como subcategoría de la sepsis en la que las alteraciones circulatorias y del metabolismo celular pueden aumentar considerablemente la mortalidad. A nivel mundial, el choque séptico ocupa el segundo lugar como causa de muerte no coronaria en la Unidad de Cuidados Intensivos (UCI), con una incidencia anual del 10%, y con una mortalidad hospitalaria de 18 a 35%. Objetivo: Describir el abordaje del Proceso de Atención de Enfermería en el paciente con choque séptico y desde la perspectiva del déficit de autocuidado. Metodología: El caso clínico se fundamentó en las etapas del Proceso de Atención de Enfermería (PAE), en la Teoría Enfermera del Déficit de Autocuidado (TEDA) de Dorothea Orem y en herramientas taxonómicas para el abordaje individualizado del plan de cuidados. Resultados: Paciente de 68 años en el servicio de Cuidados Intensivos Adultos, cursa la primera hora del posoperatorio por nefrectomía izquierda secundaria a absceso perirenal, que condiciona a choque séptico. Se abordó el PAE con apoyo del TEDA siendo prioritaria la etiqueta diagnóstica disminución del gasto cardiaco. Conclusiones: La aplicación de las teorías y modelos de enfermería proporcionan un marco de referencia para otorgar cuidados de calidad en los diferentes ámbitos de desempeño, incluyendo unidades de atención de cuidados intensivos. Resulta indispensable usar la metodología del PAE que permite dar evidencia de la profesionalización del cuidado, al usar un lenguaje técnico, con el apoyo de la Teoría de Orem y con las herramientas taxonómicas[AU]

Septic shock is a state of tissue hypoperfusion defined as a subcategory of sepsis in which circulatory and cellular metabolism alterations can considerably increase mortality. Worldwide, septic shock ranks second as a cause of non-coronary death in the Intensive Care Unit (ICU), with an annual incidence of 10%, and a hospital mortality of 18 to 35%. Objective: To describe the approach to the Nursing Care Process in patients with septic shock and from the perspective of self-care deficit. Methodology: The clinical case was based on the stages of the Nursing Care Process (PAE), on the Nursing Theory of Self-Care Deficit (TEDA) by Dorothea Orem and on taxonomic tools for the individualized approach to the care plan. Results: A 68-year-old patient, in the Adult Intensive Care service, undergoes the first postoperative hour due to left nephrectomy secondary to perirenal abscess, which conditions septic shock. The PAE was approached with the support of the TEDA, with a priority being the dignostic label reduction of cardiac output. Conclusions: The application of nursing theories and models provide a frame of reference to provide quality care in different areas of performance, including intensive care units. It is essential to use the PAE methodology that allows to give evidence of the professionalization of care, by using technical language, with the support of Orem's Theory and with taxonomic tools[AU]

Asociación entre índice de masa corporal y mortalidad en pacientes críticos con choque séptico / Association between body mass index and mortality in critical ill patients with septic shock

INTRODUCCIÓN. La paradoja de la obesidad propone que, en determinadas enfermedades, los enfermos con obesidad tienen menor mortalidad. OBJETIVO. Asociar el índice de masa corporal con la mortalidad a 30 días en adultos con choque séptico. MATERIALES Y MÉTODOS. Estudio observacional, analítico, retrospectivo, multicéntrico. Se analizaron 673 pacientes con choque séptico, ingresados en terapia intensiva de dos hospitales de la ciudad de la ciudad de Quito ­ Ecuador, durante enero 2017 - diciembre 2019. Criterios de inclusión: Mayores a 18 años, choque séptico, registro de peso, talla y condición vital al día 30. Criterios de exclusión: Orden de no reanimación, embarazadas, protocolo de donación de órganos, cuidados paliativos. Las variables se recolectaron a partir de las historias clínicas digitales y físicas de los centros participantes. Las estimaciones de riesgo calculadas se presentaron como OR (Odds Ratio) en el análisis bivariado y OR Adj (OR ajustado) para el análisis multivariado. Un valor de p <0.05 se consideró estadísticamente significativo. Todos los análisis estadísticos se realizaron usando el software estadístico R® (Versión 4.1.2). RESULTADOS. La edad promedio fue de 65 años, índice de masa corporal promedio 25,9 Kg/m2 (+4,9 Kg/m2). El 54,3% tuvo índice de masa corporal > 25 Kg/m2. La mortalidad general fue 49.2%. Sujetos con sobrepeso y obesidad tuvieron menor mortalidad, OR: 0,48 (IC 95%: 0.34, 0.68; p <0.0001) y OR 0.45 (IC 95 %: 0.28, 0.70; p =0.001) respectivamente, con similar tendencia en el análisis multivariado. Los sujetos con peso bajo tuvieron la mayor mortalidad (OR: 2.12. IC 95%: 0.91 - 5.54. p: 0.097). DISCUSIÓN. Los resultados obtenidos apoyan la teoría de paradoja de obesidad, sin embargo, no se realizó evaluación según los niveles de obesidad. CONCLUSIÓN. La mortalidad en choque séptico es menor en sujetos con sobrepeso y obesidad comparada con sujetos con peso normal o bajo peso.

The obesity paradox proposes that, in certain diseases, patients with obesity have lower mortality. OBJECTIVE. To associate body mass index with 30-day mortality in adults with septic shock. MATERIALS AND METHODS. Observational, analytical, retrospective, multicenter, retrospective study. We analyzed 673 patients with septic shock, admitted to intensive care in two hospitals in the city of Quito - Ecuador, during January 2017 - December 2019. Inclusion criteria: older than 18 years, septic shock, weight, height and vital condition at day 30. Exclusion criteria: Do not resuscitate order, pregnant women, organ donation protocol, palliative care. Variables were collected from the digital and physical medical records of the participating centers. Calculated risk estimates were presented as OR (Odds Ratio) in bivariate analysis and OR Adj (adjusted OR) for multivariate analysis. A p value <0.05 was considered statistically significant. All statistical analyses were performed using R® statistical software (Version 4.1.2). RESULTS. The mean age was 65 years, mean body mass index 25.9 kg/m2 (+4.9 kg/m2). Body mass index > 25 kg/m2 was 54.3%. Overall mortality was 49.2%. Overweight and obese subjects had lower mortality, OR: 0.48 (95% CI: 0.34, 0.68; p<0.0001) and OR 0.45 (95 % CI: 0.28, 0.70; p=0.001) respectively, with similar trend in multivariate analysis. Underweight subjects had the highest mortality (OR: 2.12. 95% CI: 0.91 - 5.54. p: 0.097). DISCUSSION. The results obtained support the obesity paradox theory, however, assessment according to obesity levels was not performed. CONCLUSIONS. Mortality in septic shock is lower in overweight and obese subjects compared to normal weight or underweight subjects.

Application of bedside ultrasound in the evaluation of volume responsiveness in patients with septic shock / 中国医师杂志

Objective:To evaluate the value of bedside ultrasound in evaluating volume responsiveness of patients with septic shock.Methods:A total of 102 patients with septic shock admitted to ICU of the First Affiliated Hospital of Hebei North University from April 2018 to February 2021 were selected. Patients were divided into response group and non-response group according to the value of stroke volume increase (ΔSV) after volume loading test (VE), and the hemodynamic parameters before and after VE were compared between the two groups. Pearson correlation was used to analyze the relationship between ΔSV and hemodynamic indexes. Receiver operating characteristic (ROC) curve was drawn to analyze the sensitivity and specificity of each hemodynamic index in evaluating volumetric reactivity in patients with septic shock.Results:Of the 102 patients, 54 responded and 48 did not. Before VE, the distensibility index of inferior vena cava (ΔIVC 1), espiratory variability index of inferior vena cava (ΔIVC 2), respiratory variability of aortic peak velocity (ΔVpeak AO), brachial artery maximum velocity variability (ΔVpeak BA) and respiratory rate of peak flow velocity of femoral artery (ΔVpeak CFA) in response group were higher than those in non-response group (all P<0.05), but there was no statistical significance in heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP) between 2 groups (all P>0.05). After VE, the HR, ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA in response group were significantly decreased, while MAP and CVP were significantly increased (all P<0.05). The CVP was significantly decreased in the non-response group ( P<0.05), while other indexes were not significantly changed. Before VE, the ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA were positively correlated with ΔSV ( r=0.589, 0.647, 0.697, 0.621, 0.766; all P<0.05). There was no correlation between CVP and ΔSV ( r=-0.345, P>0.05). Before VE, the area under the curve of ΔIVC 1, ΔIVC 2, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA were all >0.7, indicating high sensitivity and specificity. Conclusions:Bedside ultrasound monitoring ΔIVC, ΔVpeak AO, ΔVpeak BA and ΔVpeak CFA can better evaluate the volume response of patients with septic shock, and can provide a reference basis for clinical fluid resuscitation treatment.

Effects of phentolamine on cardiac function, myocardial injury index, and hemodynamics in septic patients with myocardial injury / 中国基层医药

Objective:To investigate the efficacy of phenolamine in the treatment of sepsis-induced myocardial dysfunction and its effect on cardiac function, myocardial injury index, and hemodynamics in patients.Methods:The clinical data of 79 patients with sepsis-induced myocardial dysfunction who received treatment in Huangshi Central Hospital, Edong Healthcare Group from February 2017 to February 2020 were retrospectively analyzed. These patients were divided into a control group (without phenolamine treatment, n = 41) and an observation group (with phenolamine treatment, n = 38) according to whether they received phenolamine treatment or not. Clinical efficacy, cardiac function, myocardial injury index, and hemodynamic index pre- and post-treatment were compared between the two groups. Results:There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Intensive care unit length of stay and mechanical ventilation duration in the observation group were (9.33 ± 3.52) days and 83.00 (28.50, 138.00) hours, which were significantly shorter than (12.17 ± 4.15) days and 111.00 (47.50, 169.00) hours in the control group ( t = 3.26, Z = -2.27, both P < 0.05). The response rate in the observation group was significantly higher than that in the control group [81.58% (31/38) vs. 60.98% (25/41), χ2 = 4.05, P < 0.05]. After 7 days of treatment, the left ventricular ejection fraction in each group was significantly increased, and the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in each group were significantly decreased compared with before treatment (all P < 0.05). After 7 days of treatment, the left ventricular ejection fraction in the observation group was significantly higher than that in the control group ( t = 3.29, P < 0.05), and left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly lower than those in the control group ( t = 5.94, 11.21, both P < 0.05). N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in each group were significantly decreased with time (both P < 0.05). At 24 and 72 hours and 7 days after treatment, N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in the observation group were significantly lower than those in the control group (both P < 0.05). After 7 days of treatment, heart rate in each group decreased significantly compared with that before treatment (both P < 0.05), mean arterial pressure, cardiac index, and stroke output index in each group increased significantly compared with those before treatment (all P < 0.05). After 7 days of treatment, heart rate in the observation group was significantly lower than that in the control group ( t = 4.90, P < 0.05), and mean arterial pressure, cardiac index, and stroke output index in the observation group were significantly higher than those in the control group ( t = 4.37, 3.23, 6.01, all P < 0.05). Conclusion:Phentolamine can improve hemodynamics, reduce myocardial injury and improve cardiac function in patients with sepsis-induced myocardial dysfunction.

COVID-19, shock séptico refractario y terapia extracorpórea de purificación sanguínea con OXIRIS® / Management of refractory septic shock with blood purification therapy using a special filter: report of one case

Sepsis is one of the leading causes of death in critically ill patients with COVID-19 and blood purification therapies have a role to immunomodulate the excessive inflammatory response and improve clinical results. One of the devices designed for these therapies is the oXiris® filter, allowing to perform renal replacement therapy combined with selective adsorption of endotoxins and cytokines. We report a 55-year-old male with COVID who developed a septic shock secondary to a sepsis caused by Pseudomona aeruginosa, refractory to the usual management. A veno-venous continuous hemofiltration was started using the oXiris® filter for 48 hours. Subsequently, there was an improvement in clinical perfusion parameters and a reduction in inflammatory markers. The patient was discharged from the intensive care one month later.

Compliance of sepsis hour-1 bundle strategy for patients with septic shock in emergency department / 中华全科医师杂志

Objective:To investigate the implementation status of sepsis hour-1 bundle strategy for patients with septic shock in emergency department.Methods:A total of 116 septic shock patients admitted to the emergency department from January 2020 to December 2020 were included in this prospective study, and the implementation of sepsis bundles and the clinical outcomes of patients were recorded.Results:Among 116 patients, 20 cases (17.2%) had lactic acid monitored within 1 h, 20 cases (17.2%) had blood culture before antibiotics, 82 cases (70.1%) received broad-spectrum antibiotics, 16 cases (13.8%) received fluid resuscitation ≥30 ml/kg, and 57 cases (49.1%) received vasoactive drugs during resuscitation. Finally, the sepsis hour-1 bundle strategy was fully implemented only in 13 cases (11.2%). Compared with the group with incomplete implementation of sepsis hour-1 bundle strategy, the volume of fluid recovery in the group with full implementation was significantly increased [33.7 (30.0,37.5) vs. 8.9(7.3,10.8) ml/kg, Z=-4.78, P<0.001], mean artery blood pressure significantly increased [70.0 (70.0,76.7) vs. 67.7 (61.7,76.7)mmHg(1 mmHg=0.133 kPa) , Z=-2.00, P<0.001], and lactic acid significantly decreased [3.0 (2.0,3.2) vs. 4.4 (3.7,7.2) mmol/L, Z=-2.76, P=0.006]. However, there were no significant differences in ICU mortality, in-hospital mortality and 28-day mortality between the two groups ( P>0.05). Conclusions:Septic shock patients in emergency department have poor compliance with the implementation of sepsis hour-1 bundle strategy, and relevant management training should be strengthened.

Analysis on 42 cases of septic shock caused by an invasive pneumococcal disease / 中国基层医药

Objective:To investigate the clinical characteristics of septic shock caused by an invasive pneumococcal disease (IPD) and analyze the factors that affect the prognosis of this disease.Methods:We retrospectively analyzed the clinical data of 42 children with an IPD-caused septic shock, who received treatment in The Second Hospital of Jiaxing from January 2015 to December 2020, and evaluated the clinical characteristics and prognosis of this disease.Results:The age of the included children averaged 1.3 (0.75, 4.15) years. The Pediatric Index of Mortality 2 was (23.38 ± 9.26) points. Infections were primarily in the blood and brain. Eighteen cases were sensitive to penicillin, 20 cases to cefepime, 22 cases to cefotaxime, and 20 cases to meropenem, vancomycin, and linezolid simultaneously. The mortality was 61.90% (26/42). The Pediatric Index of Mortality 2 [(37.17 ± 10.58) points vs. (0.92 ± 0.39) points, t = 17.45, P < 0.001], and the rate of children developing an intracranial hypertension crisis (69.23% vs. 25.03%) ( χ2 = 7.77, P = 0.05) were significantly higher in the death group than in the survival group. Compared with the survival group, the thoracic infection rate was significantly lower in the death group (7.69% vs. 50.00%, P < 0.05). Conclusion:Most children with an IPD-caused septic shock are young, and most infection sites are in the brain and blood. The IPD-caused septic shock is highly resistant to cephalosporins and penicillin and has high mortality because of an intracranial hypertension crisis. The IPD-caused septic shock should be screened and treated as early as possible.

Diagnostic and prognostic valuation of CD64, heparin binding protein and procalcitonin in children with sepsis shock / 中国医师进修杂志

Objective:To investigate the value of serum CD64, heparin binding protein (HBP) and procalcitonin (PCT) in early diagnosis of septic shock and its prognostic value.Methods:The clinical data of 40 children with sepsis (sepsis group) and 40 children with septic shock (septic shock group) in Children′s Hospital of Xuzhou Medical University from January 2018 to November 2021 were retrospectively analyzed. PCT was detected by chemiluminescence, HBP was detected by enzyme-linked immunosorbent assay, and CD 64 was detected by flow cytometry. All children were followed up within 1 month after discharge, and the occurrence of poor prognosis (including multiple organ failure and death) was recorded. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of serum CD 64, HBP and PCT for septic shock. Multivariate Logistic regression was used to analyze the independent risk factors for poor prognosis in children with septic shock. Results:The serum CD 64, HBP and PCT in septic shock group were significantly higher than those in sepsis group: 0.667 ± 0.120 vs. 0.501 ± 0.115, (116.46 ± 11.41) μg/L vs. (87.34 ± 23.49) μg/L and (11.41 ± 1.25) μg/L vs. (9.29 ± 1.31) μg/L respectively, and there were statistical differences ( P<0.05). ROC curve analysis result showed that the area under curve (AUC) of serum CD 64, HBP and PCT for predicting septic shock were 0.837, 0.894 and 0.880 respectively, and the optimal cut-off values were 0.586, 106.2 μg/L and 11.28 μg/L respectively; the AUC of serum CD 64, HBP and PCT combined detection for predicting septic shock was 0.914, with a sensitivity of 75.7%, specificity of 96.0%, and accuracy of 71.7%. According to the optimal cut-off values of serum CD 64, HBP and PCT, 40 children with septic shock were divided into high expression group and low expression group. The prognosis was good in 25 cases and bad in 15 cases. The incidence of poor prognosis in CD 64 high expression group, HBP high expression group and PCT high expression group was significantly higher than that in corresponding CD 64 low expression group, HBP low expression group and PCT low expression group: 56.52% (13/23) vs. 2/17, 10/17 vs. 21.74% (5/23) and 11/18 vs. 18.18% (4/22), and there was statistical difference ( P<0.01 or <0.05). Multivariate Logistics regression analysis result showed that serum CD64, HBP and PCT were independent risk factors for poor prognosis in children with septic shock ( OR = 0.818, 1.204 and 3.633; 95% CI 0.674 to 0.994, 1.022 to 1.419 and 1.090 to 12.108; P = 0.043, 0.026 and 0.036). Conclusions:The serum levels of CD 64, HBP and PCT in children with septic shock are significantly increased, which play an important role in the occurrence and development of septic shock, and which have predictive value for septic shock. The combined detection of the 3 indexes could be used to evaluate the prognosis, with a higher predictive value.

ABSTRACT Objective To describe the clinical characteristics and treatment of children with sepsis, severe sepsis, and septic shock at a pediatric emergency department of a public hospital. Methods A retrospective, observational study. The medical records of patients included in the hospital Pediatric Sepsis Protocol and patients with discharge ICD-10 A41.9 (sepsis, unspecified), R57 (shock) and A39 (meningococcal meningitis) were evaluated. Results A total of 399 patients were included. The prevalence of sepsis, severe sepsis, and septic shock at the emergency room were 0.41%, 0.14% and 0.014%, respectively. The median age was 21.5 months for sepsis, 12 months for severe sepsis, and 20.5 months for septic shock. Sepsis, severe sepsis, and septic shock were more often associated with respiratory diseases. The Respiratory Syncytial Virus was the most common agent. The median time to antibiotic and fluid administration was 3 hours in patients with sepsis and severe sepsis. In patients with septic shock, the median times to administer antibiotics, fluid and vasoactive drugs were 2 hours, 2.5 hours and 6 hours, respectively. The median length of hospital stay for patients with sepsis, severe sepsis and septic shock were 3 days, 4 days and 1 day, respectively. The overall mortality was 2%. Conclusion Sepsis had a low prevalence. Early diagnosis and recognition are a challenge for the emergency care pediatrician, the first place of admission.

Early neonatal sepsis: prevalence, complications and outcomes in newborns with 35 weeks of gestational age or more / Sepse neonatal precoce: prevalência, complicações e desfechos em recém-nascidos com 35 semanas ou mais de idade gestacional

ABSTRACT Objective: To analyze the incidence, complications, and hospital discharge status in newborns with ≥35 weeks of gestational age with early neonatal sepsis. Methods: This is a cross-sectional, retrospective study. Cases of early-onset sepsis registered from January 2016 to December 2019 in neonates with gestational age of 35 weeks or more were reviewed in a level III neonatal unit. The diagnoses were performed based on the criteria by the Brazilian Health Regulatory Agency (Anvisa), and the episodes were classified according to microbiological classification and site of infection. The following complications were evaluated: shock, coagulation disorders, and sequelae of the central nervous system. The conditions at hospital discharge were also assessed. The collected data were analyzed with the descriptive analysis. Results: In the period, early neonatal sepsis occurred in 46 newborns, corresponding to 1.8% of all newborns admitted to the neonatal unit, with a prevalence of 4/1,000 live births. Culture confirmed sepsis ocurred in three patients (0.3/1,000 live births), with the following agents: S. pneumoniae, S. epidermidis and S. agalactiae. As to site of infection, there were 35 cases of primary bloodstream infection, seven cases of pneumonia and four cases of meningitis. Most patients (78.3%) had at least one risk factor for sepsis, and all were symptomatic at admission. There were no deaths. Complications occurred in 28.2% of the cases, especially shock (10 cases - 21.7%). Conclusions: The prevalence of proven early neonatal sepsis was low. Despite the common occurrence of complications, there were no deaths.

RESUMO Objetivo: Analisar a prevalência, as complicações e as condições de alta dos recém-nascidos ≥35 semanas com diagnóstico de sepse neonatal precoce. Métodos: Estudo transversal, com coleta retrospectiva de dados. Incluíram-se todos recém-nascidos com 35 semanas ou mais de idade gestacional, com diagnóstico de sepse precoce em um período de quatro anos (janeiro/2016 a dezembro/2019) em uma unidade neonatal nível III. Os diagnósticos realizaram-se segundo os critérios da Agência Nacional de Vigilância Sanitária e os episódios classificados segundo a confirmação microbiológica e o sítio de infecção. As complicações avaliadas foram: choque, distúrbio de coagulação e sequelas do sistema nervoso central. Também se avaliaram as condições de alta. Os dados coletados foram analisados utilizando estatística descritiva. Resultados: No período, 46 recém-nascidos apresentaram sepse precoce, correspondendo a 1,8% das internações e a uma prevalência de 4/1.000 nascidos vivos. Em três pacientes a sepse foi confirmada por culturas (0,3/1.000 nascidos vivos), respectivamente por S. pneumoniae, S. epidermidis e S. agalactiae.

Anesthetic management of a parturient with Marfan syndrome scheduled for cesarean section: case report and review of literature / Manejo anestésico de una parturienta con síndrome de Marfan programada para cesárea: informe de un caso y revisión de la literatura

Abstract: Introduction: Marfan syndrome is an inherited disorder that affects connective tissue. Case: We report the anesthetic management of a parturient with Marfan syndrome scheduled for an elective C-section. Successful use of a combined spinal-epidural technique was used to provide neuraxial anesthesia; however, she presented an unfavorable evolution due to maternal sepsis. Likewise, a literature review of combined spinal-epidural anesthesia for C-sections in Marfan syndrome pregnant women was performed. Conclusion: Anesthetic management of parturients affected by Marfan syndrome during the cesarean section can be challenging. Strict blood pressure control during the intraoperative period has cornerstone importance. Likewise, neuraxial techniques have a significant percentage of failure in these patients.

Resumen: Introducción: El síndrome de Marfan es un desorden hereditario que afecta el tejido conectivo. Caso: Reportamos el manejo anestésico de una parturienta con síndrome de Marfan programada para una cesárea electiva. Para administrar anestesia neuroaxial se utilizó un bloqueo combinado espinal-epidural; sin embargo, la paciente presentó una evolución desfavorable debido a sepsis materna. Asimismo, se realizó una revisión de la literatura del uso de esta técnica anestésica para cesárea en gestantes con síndrome de Marfan. Conclusión: El manejo anestésico de parturientas afectadas por este síndrome puede ser complicado. El control estricto de la presión arterial durante el intraoperatorio tiene importancia fundamental. Además, las técnicas neuroaxiales tienen un porcentaje significativo de fallo en estas pacientes.

Shock séptico, hipercalcemia y síndrome hemofagocítico por paracoccidioidomicosis en una niña de 3 años / Septic shock, hypercalcemia and hemophagocytic syndrome due to paracoccidioidomycosis in a 3-year-old girl

Objetivo: Reportar el caso de una niña que presentó shock séptico, hipercalcemia y síndrome hemofagocítico por paracoccidioidomicosis. Reporte de caso: Paciente mujer de 3 años con 2 meses de enfermedad caracterizada por fiebre, adenopatías, pérdida de peso, distensión abdominal y anemia severa. Llegó en mal estado general, desarrolló shock séptico y un síndrome hemofagocítico. Llamaba la atención la hipercalcemia y lesiones dérmicas. Se le realizó una biopsia de ganglio cervical y aspirado de médula ósea. En esta última se evidenciaron imágenes compatibles con Paracoccidioides, que fueron confirmadas con la tinción de Grocott del ganglio. Se trató con anfotericina B y trimetoprim-sulfametoxazol. La evolución fue favorable y el calcio sérico se mantuvo en rangos normales. Conclusión: Las complicaciones presentadas por paracoccidioidomicosis son raras; sin embargo, el antecedente epidemiológico y el aspirado de médula ósea pueden orientar el diagnóstico y permitir un tratamiento oportuno.

Objetive: Report the case of a girl who presented septic shock, hypercalcemia and hemophagocytic syndrome due to paracoccidioidomycosis. Case report: 3-year-old female patient with 2-month illness characterized by fever, lymphadenopathy, weight loss, abdominal distention, and severe anemia. She arrived in poor general condition, developed septic shock and a hemophagocytic syndrome. The hypercalcemia and dermal lesions were striking. Acervical ganglion biopsy and bone marrow aspirate were performed. In the latter, images compatible with Paracoccidioides were found, which were then confirmed with Grocott's stain. She was treated with amphotericin B and trimethoprim-sulfamethoxazole. The evolution was favorable and serum calcium came back to normal ranges. Conclusion: Complications caused by paracoccidioidomycosis are rare; however, the epidemiological history and bone marrow aspirate should guide the diagnosis and allow prompt treatment.

Impacto da transfusão de eritrócitos no transporte e no metabolismo de oxigênio em pacientes com sepse e choque séptico: uma revisão sistemática e metanálise / Impact of red blood cell transfusion on oxygen transport and metabolism in patients with sepsis and septic shock: a systematic review and meta-analysis

RESUMO Considera-se que a transfusão de eritrócitos melhora a respiração celular durante o choque séptico. Contudo, seu impacto agudo no transporte e no metabolismo de oxigênio nessa condição ainda é amplamente debatido. O objetivo deste estudo foi avaliar o impacto da transfusão de eritrócitos na microcirculação e no metabolismo do oxigênio em pacientes com sepse e choque séptico. Conduzimos um levantamento nas bases de dados MEDLINE®, Elsevier e Scopus. Incluímos estudos realizados com seres humanos adultos com sepse e choque séptico. Realizamos uma revisão sistemática e metanálise com utilização do modelo de efeitos aleatórios de DerSimonian e Laird. Consideramos significante valor de p < 0,05. Incluíram-se na análise 19 manuscritos, correspondentes a 428 pacientes. As transfusões de eritrócitos se associaram com aumento de 3,7% na média combinada de saturação venosa mista de oxigênio (p < 0,001), diminuição de razão de extração de oxigênio de -6,98 (p < 0,001) e nenhum efeito significante no índice cardíaco (0,02 L/minuto; p = 0,96). Obtiveram-se resultados similares em estudos que incluíram mensurações simultâneas de saturação venosa mista de oxigênio, razão de extração de oxigênio e índice cardíaco. As transfusões de eritrócitos levaram a aumento significante na proporção de pequenos vasos perfundidos (2,85%; p = 0,553), enquanto os parâmetros de oxigenação tissular revelaram aumento significante no índice de hemoglobina tissular (1,66; p = 0,018). Estudos individuais relataram melhoras significantes na oxigenação tissular e nos parâmetros microcirculatórios sublinguais em pacientes com microcirculação alterada na avaliação inicial. A transfusão de eritrócitos pareceu melhorar o metabolismo sistêmico de oxigênio com aparente independência de variações no débito cardíaco. Observaram-se alguns efeitos benéficos para a oxigenação tissular e parâmetros microcirculatórios, em particular em pacientes com alterações iniciais mais graves. São necessários mais estudos para avaliar seu impacto clínico e individualizar as decisões relativas à transfusão.

ABSTRACT Red blood cell transfusion is thought to improve cell respiration during septic shock. Nevertheless, its acute impact on oxygen transport and metabolism in this condition remains highly debatable. The objective of this study was to evaluate the impact of red blood cell transfusion on microcirculation and oxygen metabolism in patients with sepsis and septic shock. We conducted a search in the MEDLINE®, Elsevier and Scopus databases. We included studies conducted in adult humans with sepsis and septic shock. A systematic review and meta-analysis were performed using the DerSimonian and Laird random-effects model. A p value < 0.05 was considered significant. Nineteen manuscripts with 428 patients were included in the analysis. Red blood cell transfusions were associated with an increase in the pooled mean venous oxygen saturation of 3.7% (p < 0.001), a decrease in oxygen extraction ratio of -6.98 (p < 0.001) and had no significant effect on the cardiac index (0.02L/minute; p = 0,96). Similar results were obtained in studies including simultaneous measurements of venous oxygen saturation, oxygen extraction ratio, and cardiac index. Red blood cell transfusions led to a significant increase in the proportion of perfused small vessels (2.85%; p = 0.553), while tissue oxygenation parameters revealed a significant increase in the tissue hemoglobin index (1.66; p = 0.018). Individual studies reported significant improvements in tissue oxygenation and sublingual microcirculatory parameters in patients with deranged microcirculation at baseline. Red blood cell transfusions seemed to improve systemic oxygen metabolism with apparent independence from cardiac index variations. Some beneficial effects have been observed for tissue oxygenation and microcirculation parameters, particularly in patients with more severe alterations at baseline. More studies are necessary to evaluate their clinical impact and to individualize transfusion decisions.

RESUMEN Un nuevo coronavirus, denominado COVID-19, fue descubierto por el brote iniciado en China a finales de diciembre del año 2019. Los síntomas característicos son fiebre, tos seca, dificultad respiratoria y malestar general. Muchas investigaciones se están llevando a cabo ya que, si bien no es una enfermedad considerada mortal, tiene un índice de contagio muy alto. Sin embargo, junto a los cuidados hospitalarios y extrahospitalarios, existe un grupo de fármacos que se vienen utilizando para combatir esta enfermedad, tales como hidroxicloroquina, cloroquina, remdesivir, lopinavir/ritonavir, tocilizumab, interferón beta 1B, entre otros.

ABSTRACT A novel coronavirus disease called COVID-19 was discovered as a result of the outbreak that began in China at the end of December 2019. Common symptoms are fever, dry cough, shortness of breath and malaise. Several research are being conducted since the disease has high transmission rate even though it is not considered life-threatening. However, together with hospital and out-of-hospital care, there is a group of medications being used to fight this disease, such as hydroxychloroquine, chloroquine, remdesivir, lopinavir/ritonavir, tocilizumab, interferon beta-1b, among others.

Correlation of arterial blood lactic acid level in patients with septic shock and mortality 28 days after entering the intensive care unit / 中国医师杂志

Objective:To investigate the relationship between the arterial blood lactic acid level after entering the intensive care unit (ICU) and the 28-day mortality of patients with septic shock.Methods:The clinical data of 303 patients with septic shock hospitalized in the department of critical medicine of the Affiliated Hospital of Jining Medical College from April 2015 to June 2019 were analyzed retrospectively. According to the blood lactate (Lac) level, the patients were divided into <4 mmol/L group ( n=203), 4-10 mmol/L group ( n=69) and >10 mmol/L group ( n=31). The baseline characteristics of the patients were analyzed. Multiple logistic regression analysis was used to analyze the independent influencing factors of the 28-day mortality of patients with septic shock. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of the Lac level after entering the ICU for 28-day mortality, and Kaplan-Meier survival curve was performed according to the best cut-off value. Results:A total of 303 patients with septic shock were included, with 179 died in 28 days, and the total mortality was 59.08%. There were 203, 69, 31 patients in Lac<4 mmol/L, 4-10 mmol/L and >10 mmol/L group, respectively. There were significant differences in Acute Physiology and Chronic Health Evalution Ⅱ (APACHE Ⅱ), Sequential Organ Failure Assessment (SOFA), oxygenation index (PaO 2/FiO 2), abdominal infection, the proportion of vasoactive drugs use among the three groups ( P<0.05). Multiple logistic regression analysis showed that the independent influencing factor of the 28-day mortality of septic shock were age, SOFA, use of mechanical ventilation, lactic acid (Lac). ROC curve analysis showed that the area under the ROC curve (AUC) for predicting 28-day mortality of patients with septic shock was 0.604 5 (95% CI: 0.540 8-0.668 2). When the optimal cut-off value was 3.55 mmol/L, the sensitivity was 0.508 4, the specificity was 0.733 9, the positive likelihood ratio was 1.910 3 and the negative likelihood ratio was 0.669 9. According to the best cut-off value of entrance Lac, patients were divided into high Lac group (≥3.55 mmol/L) and low Lac group (<3.55 mmol/L), and their 28-day mortality rates were 73.39%(91/124) and 49.16%(88/179). Kaplan-Meier survival curve showed that the 28-day cumulative survival rate of the high Lac group was significantly lower than that of the low Lac group ( P<0.001). Multiple logistic regression analysis showed that after adjusting for confounding factors, the 28 d mortality increased to 1.22 times for each increase of 1 mmol/L of Lac [odds ratio ( OR)=1.22, 95% confidence interval (95% CI) was 1.08-1.37, P=0.001 4]. The 28 d mortality in high Lac group was 3.53 times higher than that in low Lac group ( OR=3.53, 95% CI was 1.36-7.09, P=0.000 4). Conclusions:In patients with ICU septic shock, the arterial blood Lac level after admission was associated with 28-day mortality. Patients with septic shock whose arterial blood Lac level exceeded 3.55 mmol/L within 1 hour of entering the room had a significantly increased risk of death.

Prognostic values of the plasma trimethylamine N-oxide in sepsis / 中国医师杂志

Objective:To investigate the value of serum trimethylamine N-oxide (TMAO) level in evaluating the severity and short-term clinical prognosis of patients with sepsis.Methods:A prospective case-control study was conducted. Patients in the case group were admitted to the emergency intensive care unit of Shanghai Putuo District People′s Hospital Affiliated to Tongji University from March 2018 to December 2019. According to the diagnosis criteria of sepsis 3.0 in 2016, the patients in the case group were divided into sepsis non shock group (33 cases) and septic shock group (12 cases). They were divided into survival group and death group according to 28 day outcome; Healthy volunteers were selected as control group (30 cases). The levels of C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), Acute Physiology And Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and the sequential organ failure assessment (SOFA), serum TMAO were compared. The relationship between serum TMAO, sepsis severity and short-term clinical prognosis were analyzed.Results:The serum IL-6, CRP, PCT, scores of SOFA and APACHE Ⅱ in septic shock group were significantly higher than those in normal sepsis group ( P<0.01). The serum IL-6, PCT, scores of SOFA and APACHE Ⅱ in the death group of sepsis patients were significantly higher than those in the survival group ( P<0.01). The serum TMAO level of the sepsis group on 1st day was significantly higher than that of the healthy control group ( P<0.01). The serum TMAO level in the septic shock group on the 1st, 3rd and 7 th day was higher than that in the normal sepsis group, with statistically significant difference ( P<0.01). The serum TMAO level in the septic shock group and normal sepsis group on the third day were significant different with the first day ( P<0.01). The serum TMAO level in the death group on the 1st, 3rd and 7th day was higher than that in the survival group, with statistically significant difference ( P<0.05). And the serum TMAO level in the death group and survival group on the third day were significant different with the first day ( P<0.01). The serum TMAO level of sepsis patients was positively correlated with APACHE Ⅱ score ( r=0.848, P<0.01). The level of TMAO was positively correlated with serum IL-6 ( r=0.956, P<0.01). Conclusions:Serum TMAO is closely related to the severity and recent clinical prognosis of patients with sepsis, and is a risk factor for the death of patients with sepsis.
