Development, Histological, and Ultrastructural Evaluation of Sheep Hyperimmune Serum Therapy for COVID-19 / Desarrollo, Evaluación Histológica y Ultraestructural de la Terapia con Suero Hiperinmune de Oveja para COVID-19

SUMMARY: In response to the threat posed by new variants of SARS-CoV-2 and the urgent need for effective treatments in the absence of vaccines, the aim of this study was to develop a rapid and cost-effective hyperimmune serum (HS) derived from sheep and assess its efficacy. The utilization of a halal-certified, easily maintained in certain geographic regions, easy-to-handle animal such as sheep could provide a viable alternative to the expensive option of horses. Sheep were immunized with a whole inactivated SARS-CoV- 2 antigen to produce HS, which was evaluated for neutralizing potency using the PRNT50 assay. K18-hACE2 transgenic mice (n=35) were divided into three groups: control, SARS-CoV-2 exposure through inhalation, and SARS-CoV-2 exposed mice treated with HS. HS efficacy was assessed through serum proinflammatory cytokine levels, qRT-PCR analysis, histopathological examination of lungs and hearts, and transmission electron microscopy. Purified HS exhibited significant neutralizing activity (1/24,576). The SARS-CoV-2+HS group showed lower levels of TNF-α, IL-10, and IL-6 (P<0.01) and relatively lower levels of MCP-1 compared to the SARS-CoV-2 group. HS prevented death, reduced viral RNA levels in the lungs and hearts, protected against severe interstitial pneumonia, preserved lung tissue integrity, and prevented myocyte damage, while the SARS-CoV-2 group exhibited viral presence in the lungs. This study successfully developed a sheep-derived HS against the entire SARS-CoV-2 virus, resulting in a significant reduction in infection severity, inflammation, and systemic cytokine production. The findings hold promise for treating severe COVID-19 cases, including emerging viral variants, and immunocompromised patients.

En respuesta a la amenaza que suponen las nuevas variantes del SARS-CoV-2 y la urgente necesidad de tratamientos eficaces en ausencia de vacunas, el objetivo de este estudio fue desarrollar un suero hiperinmune (HS) rápido y rentable derivado de ovejas. y evaluar su eficacia. La utilización de un animal con certificación halal, de fácil mantenimiento en determinadas regiones geográficas y de fácil manejo, como las ovejas, podría proporcionar una alternativa viable a la costosa opción de los caballos. Las ovejas fueron inmunizadas con un antígeno de SARS-CoV-2 completamente inactivado para producir HS, cuya potencia neutralizante se evaluó mediante el ensayo PRNT50. Los ratones transgénicos K18-hACE2 (n = 35) se dividieron en tres grupos: control, exposición al SARS-CoV-2 mediante inhalación y ratones expuestos al SARS-CoV-2 tratados con HS. La eficacia de HS se evaluó mediante niveles de citoquinas proinflamatorias en suero, análisis qRT-PCR, examen histopatológico de pulmones y corazones y microscopía electrónica de transmisión. El HS purificado exhibió una actividad neutralizante significativa (1/24,576). El grupo SARS-CoV-2+HS mostró niveles más bajos de TNF-α, IL-10 e IL-6 (P<0,01) y niveles relativamente más bajos de MCP-1 en comparación con el grupo SARS-CoV-2. HS evitó la muerte, redujo los niveles de ARN viral en los pulmones y el corazón, protegió contra la neumonía intersticial grave, preservó la integridad del tejido pulmonar y evitó el daño de los miocitos, mientras que el grupo SARS-CoV-2 exhibió presencia viral en los pulmones. Este estudio desarrolló con éxito un HS derivado de ovejas contra todo el virus SARS-CoV-2, lo que resultó en una reducción significativa de la gravedad de la infección, la inflamación y la producción sistémica de citocinas. Los hallazgos son prometedores para el tratamiento de casos graves de COVID- 19, incluidas las variantes virales emergentes y los pacientes inmunocomprometidos.

Comparison between selective head cooling and whole-body cooling in neonatal therapeutic hypothermia / Comparação entre resfriamento seletivo da cabeça e resfriamento de corpo inteiro na hipotermia terapêutica neonatal

INTRODUCTION: Experimental evidence, as well as improved clinical studies of the reduction of brain injury and, improves the neurological outcome, in newborns with hypoxic-ischemic encephalopathy (HIE) occurring in therapeutic hypothermia (TH). OBJECTIVE: To verify the potential of hypothermic hypoxic-ischemic encephalopathy (HIE) therapy in neonatal asphyxia, based on literature data, comparing the benefits between selective head cooling (SHC) and whole-body cooling (WBC), see that the use of TH as a standard treatment in newborns with moderate or severe HIE has been adopted. METHODS: A search was performed in the PubMed and SciELO databases of human studies, using the keywords "Therapeutic Hypothermia", "Induced Hypothermia", and "Hypoxic-Ischemic Encephalopathy", "Selective cooling of the head", "Total body cooling" and its variables. RESULTS: Eleven articles were selected to compose the review, after detailed reading. There is a consensus, that the reduction of the risk of death or disability at 18 months of life in neonates with moderate to severe HIE, occurs to TH through the techniques of WBC or SHC. It was found in the studies that there is no difference in terms of adverse effects between the two methods. As for radiological changes, such as hypoxic-ischemic injuries and the incidence of seizures after cooling, they are more frequent with SHC. CONCLUSION: Both WBC and SHC demonstrated neuroprotective properties, although WBC provides a broader area of brain protection. However, no significant differences were found between the methods in terms of adverse effects and beneficial short or long-term results.

Advances in the effect of inhibiting complement activation in the treatment of sepsis-associated coagulopathy / 中华危重病急救医学

Sepsis-associated coagulopathy refers to extensive coagulation activation accompanied by a high risk of bleeding and organ failure. In severe cases, it is manifested as disseminated intravascular coagulation (DIC) and leads to multiple organ dysfunction syndrome (MODS). Complement is an important component of the innate immune system and plays an important role in defending against invasion of pathogenic microorganisms. The early pathological process of sepsis involves excessive activation of the complement system, which forms an extremely complex network through interactions with the coagulation, kinin and fibrinolytic system, amplifying and exacerbating the systemic inflammatory response. In recent years, it has been suggested that uncontrolled complement activation system can exacerbate sepsis-associated coagulation dysfunction or even DIC, indicating the potential value of intervening in the complement system in the treatment of septic DIC, and related research progress is reviewed in this article in order to provide new ideas for the discovery of sepsis-associated coagulopathy therapy drugs.

Clinical characteristics of plastic bronchitis and risk factors for recurrence in children / 中国当代儿科杂志

OBJECTIVES@#To study the clinical characteristics of plastic bronchitis (PB) in children and investigate the the risk factors for recurrence of PB.@*METHODS@#This was a retrospective analysis of medical data of children with PB who were hospitalized in Children's Hospital of Chongqing Medical University from January 2012 to July 2022. The children were divided into a single occurrence of PB group and a recurrent PB group and the risk factors for recurrence of PB were analyzed.@*RESULTS@#A total of 107 children with PB were included, including 61 males (57.0%) and 46 females (43.0%), with a median age of 5.0 years, and 78 cases (72.9%) were over 3 years old. All the children had cough, 96 children (89.7%) had fever, with high fever in 90 children. Seventy-three children (68.2%) had shortness of breath, and 64 children (59.8%) had respiratory failure. Sixty-six children (61.7%) had atelectasis and 52 children (48.6%) had pleural effusion. Forty-seven children (43.9%) had Mycoplasma pneumoniae infection, 28 children (26.2%) had adenovirus infection, and 17 children (15.9%) had influenza virus infection. Seventy-one children (66.4%) had a single occurrence of PB, and 36 cases (33.6%) had recurrent occurrence of PB (≥2 times). Multivariate logistic regression analysis showed that involvement of ≥2 lung lobes (OR=3.376) under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts (OR=3.275), and concomitant multi-organ dysfunction outside the lungs (OR=2.906) were independent risk factors for recurrent occurrence of PB (P<0.05).@*CONCLUSIONS@#Children with pneumonia accompanied by persistent high fever, shortness of breath, respiratory failure, atelectasis or pleural effusion should be highly suspected with PB. Involvement of ≥2 lung lobes under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts, and concomitant multi-organ dysfunction outside the lungs may be risk factors for recurrent occurrence of PB.

Cirrosis hepática o falla hepática crónica agudizada: definición y clasificación / Cirrhosis or acute-on-chronic liver failure: definition and classification

Objetivo: la cirrosis se considera el estadio crónico e irreversible de la lesión hepática. Su etiología es diversa y abarca causas como las infecciones víricas, tóxicos como el alcohol, medicamentos, patologías autoinmunes y otras. Discusión: la descompensación de la cirrosis hepática es consecuencia de cambios fisiopatológicos que se dan con el tiempo como ascitis, peritonitis bacteriana espontánea, hemorragia del tubo digestivo, síndrome hepatorrenal, encefalopatía hepática o hipertensión portopulmonar, mientras que la falla hepática crónica agudizada debe considerarse como una entidad que debe diferenciarse de la anterior, ya que es una falla multiorgánica de curso rápido, por lo regular en pacientes hospitalizados en unidad de cuidado intensivo, a menudo secundaria a desencadenantes como estados de choque. El clínico debe identificarlas para su abordaje y evaluación. Conclusiones: el método actual adecuado para estadificar esta entidad es el puntaje CLIFF SOFA, que evalúa la mortalidad a 28 y 90 días, permitiendo intervenciones adecuadas en cada caso.

Objetive: cirrhosis is considered the chronic and irreversible stage of liver injury. Its etiology is diverse and includes causes such as viral infection, toxic substances such as alcohol, drugs, autoimmune conditions and others. Discussion: decompensated cirrhosis is a consequence of pathophysiological changes that occur over time, such as ascites, spontaneous bacterial peritonitis, gastrointestinal hemorrhage, hepatorenal syndrome, hepatic encephalopathy or portopulmonary hypertension, while acute-on-chronic liver failure (ACLF) should be differentiated from cirrhosis, for it is a multiple organ failure of rapid clinical course, usually in patients in the intensive care unit, often secondary to precipitating events such as shock. The clinician must identify the difference between the two for an appropriate approach and evaluation. Conclusion: the current suitable method to stage this entity is the CLIFF SOFA score, which evaluates 28-day and 90-day mortality risk factors, allowing appropriate interventions in each case.

On November 6, 2019, a 54-year-old male patient was admitted to the hospital. The patient's lower limbs were red, swollen, and painful with ecchymosis and hemorrhagic bullae after he ate freshwater products. The emergency fasciotomy was performed 3 h after admission, and the multiple organ failure occurred after operation. The patient was given up treatment 24 h after admission. On August 12, 2020, a 73-year-old male patient was admitted to the hospital. He was in shock state on admission and had hemorrhagic bullae on his right lower limb after he ate seafood. At 3 h post admission, he underwent emergency surgical exploration and amputation of right thigh. Six days later, he received negative pressure wound treatment on the stump. On the 13th day post admission, his families forgo the active treatment and he died 15 d after admission. The two cases were both failed to be diagnosed at the first time, and the disease progressed rapidly. Necrotizing fasciitis and multiple organ failure occurred. After the diagnosis was confirmed, timely fasciotomy and high amputation were performed respectively. The microbiological examinations both reported Vibrio vulnificus. Although the 2 cases were not cured successfully, the course of disease and some indexes of patient with early amputation were better than those of patients with fasciotomy. Vibrio vulnificus is widely distributed and frequently detected in fresh water products. The pathogenic pathway is fuzzy and complex, and it is easy to be misdiagnosed. It is necessary to establish the treatment process of Vibrio vulnificus sepsis. Early and aggressive surgical intervention should be carried out as soon as possible, fasciotomy and debridement should be thorough, and the patients with hemorrhagic bullae should be amputated early. Postoperative comprehensive measures are also important for improving the survival rate of patients.

STING1 in sepsis: Mechanisms, functions, and implications / 中华创伤杂志(英文版)

Sepsis is a life-threatening clinical syndrome and one of the most challenging health problems in the world. Pathologically, sepsis and septic shock are caused by a dysregulated host immune response to infection, which can eventually lead to multiple organ failure and even death. As an adaptor transporter between the endoplasmic reticulum and Golgi apparatus, stimulator of interferon response cGAMP interactor 1 (STING1, also known as STING or TMEM173) has been found to play a vital role at the intersection of innate immunity, inflammation, autophagy, and cell death in response to invading microbial pathogens or endogenous host damage. There is ample evidence that impaired STING1, through its immune and non-immune functions, is involved in the pathological process of sepsis. In this review, we discuss the regulation and function of the STING1 pathway in sepsis and highlight it as a suitable drug target for the treatment of lethal infection.

Síndrome Inflamatória Multissistêmica associada à COVID-19: uma complicação pediátrica da pandemia / COVID-19-associated Multisystem Inflammatory Syndrome: a pediatric complication during the pandemic

Desde o surgimento da pandemia de COVID-19, casos de febre e inflamação sistêmica tardias, similares à Doença de Kawasaki, têm surgido na população pediátrica, sendo denominados Síndrome Inflamatória Multissistêmica associada à COVID-19. Estes quadros podem ir de apenas febre prolongada, até grave envolvimento gastrointestinal e cardíaco, com choque refratário e falência de múltiplos órgãos. Aneurismas de carótida podem surgir na evolução, levando a complicações em longo prazo. O pronto reconhecimento desta entidade com tratamento precoce de suporte geral, uso de imunoglobulina humana endovenosa e outras drogas imunomoduladoras, pode evitar evolução para casos graves e até mesmo fatais, assim como proteger o paciente de complicações crônicas, principalmente cardíacas.

Since the emergence of the COVID-19 pandemic, cases of late fever and systemic inflammation similar to Kawasaki Disease have appeared in the pediatric population, this entity was called Multisystem Inflammatory Syndrome associated with COVID-19. The presentation can range from just prolonged fever to severe gastrointestinal and cardiac involvement with refractory shock and multiple organ failure. Carotid aneurysms can arise in the course leading to long-term complications. The prompt recognition of this syndrome with early treatment with general support, use of Human Intravenous Immunoglobulin and other immunomodulatory drugs, can prevent progression to severe and even fatal cases, as well protect the patient from chronic complications, especially the cardiac ones.

Factores asociados a la mortalidad en pacientes con síndrome de disfunción multiorgánica / Fatores associados à mortalidade em pacientes com síndrome de disfunção de múltiplos órgãos / Mortality associated factors in patients with multiorgan dysfunction síndrome

Introducción:El síndrome de disfunción multiorgánica se caracteriza por el desarrollo de disfunción progresiva y potencialmente reversible en dos o más órganos inducido por una amplia variedad de agresiones. En su patogenia el sistema inmunológico-inflamatorio desempeña un papel indispensable. Objetivo:Determinar factores asociados a la mortalidad en pacientes con síndrome de disfunción multiorgánica. Método: Se desarrolló un estudio observacional analítico de cohorte retrospectivo en 68 pacientes con síndrome de disfunción multiorgánica atendidos en el servicio de Medicina Intensiva del Hospital General Docente Abel Santamaría Cuadrado de Pinar del Río, durante los años 2018 y 2019. Se midieron variables, como: edad, sexo, diagnóstico al ingreso, valoración nutricional, puntuación según Sequential Organ Failure Assessment (SOFA), complicaciones desarrolladas, sistemas en fallo y número de órganos en fallo. Resultados: Se encontró predominio de pacientes masculinos 60,3 por ciento y del grupo de edades entre 60 años y 79 años 47,06 por ciento. Hubo asociación estadísticamente significativa (p<0,05) entre la puntuación SOFA y el número de órganos en fallo con el estado al egreso. Las complicaciones respiratorias se manifestaron tanto en el 36 por ciento de los pacientes fallecidos como en el 38,89 por ciento de los egresados vivos. Se encontró un mayor número de pacientes con fallo cardiovascular 77,94 por ciento.El fallo respiratorio (p<0,001, OR:9 IC:2,52-32,08) y SOFA ≥ 16 (p<0,042, OR:8,76 IC:1,07-71,51) incrementaron el riesgo de egresar fallecido. Conclusiones: El sobrepeso y la obesidad, el choque al ingreso, altos valores SOFA, el fallo respiratorio y nervioso, así como un mayor número de órganos en fallo se asociaron con peores pronósticos y mayor probabilidad de fallecer (AU)

Introduction: Multiorgan dysfunction syndrome is characterized by the development of a progressive and potentially reversible physiological dysfunction in two or more organs induced by a wide variety of aggresive situations. The immune-inflammatory system plays an indispensable role in its pathogenesis. Objective:To identify the mortality-associated factors in patients with multiorgan dysfunction syndrome. Method: An analytical, observational, and retrospective cohort study was developed in 68 patients with multiorgan dysfunction syndrome attended in the Intensive Care Medicine Service at the Hospital General Docente Abel Santamaría Cuadrado, Pinar del Río, between 2018 and 2019. Variables used: age, sex, diagnosis at admission, nutritional assessment, score accordind to Sequential Organ Failure Assessment (SOFA), complications arose, systems and number of organs in failing process. Results: Male patients (60.3 percent) and age group between 60 and 79 (47.06 percent) were predominant. There was statistically significant association (p<0.05) between SOFA score and the number of failing organs at discharge. Respiratory complications were reported in 36 percent of deceased patients and in 38.89 percent of those discharged alive. Patients with cardiovascular failure were the most common (77.94 percent). Respiratory failure (p<0.001, OR:9 CI:2.52-32.08) and SOFA≥16 (p<0.042, OR:8.76 CI:1.07-71.51) increased the risk of decease-related discharge. Conclusions: Excessive body mass index and obesity, admission shock, high score of SOFA, respiratory and nerveous failure, as well as the enormeus failure of organs were associated with the worsen prognoses and with the highest probability of decease (AU)

Fracaso multiorgánico secundario a infección por coronavirus no COVID-19 / Multiple-organ failure as a result of non-COVID-19 coronavirus infection

Las infecciones por coronavirus son habituales en los pacientes pediátricos. Por lo general, producen un cuadro clínico leve de infección del tracto respiratorio superior que no suele afectar a los pulmones, salvo en prematuros y niños con enfermedades crónicas de base. Excepcionalmente, afectan a otros órganos (corazón, cerebro, tracto gastrointestinal) e incrementan su gravedad.En relación con la coincidencia temporal con el inicio de la actual pandemia por el nuevo beta coronavirus (SARS-CoV-2), responsable de su enfermedad asociada (COVID-19), se presenta el caso clínico de un paciente de 5 años con fracaso multiorgánico y secuelas neurológicas por afectación bulbar y trombosis vascular ocasionados por un alfa coronavirus (CoV-NL63) debido a su gravedad y excepcionalidad

Coronavirus infections (CoV) are common in pediatric patients. In general, they produce a mild clinical presentation consisting of an upper respiratory tract infection that does not usually infect the lungs, with the exception of preterm infants and children with chronic diseases. These infections exceptionally affect other organs (heart, brain, gastrointestinal tract), thus increasing their severity.In relation to the temporal coincidence with the beginning of the current situation of pandemic by the new beta coronavirus SARS-CoV-2 responsible for its associated disease (COVID-19), this study presents a clinical case of a 5-year-old patient showing multiple-organ failure and neurological sequelae due to bulbar injury and vascular thrombosis caused by an alpha coronavirus (CoV-NL63) due to its severity and exceptionality
