ABSTRACT

To study the effect of 50% ethanol extract of Bougainvillea xbuttiana on the enzymatic activity, cell via bility and cytokine production provoked by the venom of Bothrops jararaca in macro - phages. Three assays were used to study the effects of B. xbuttiana extract on the damage pro - duced by B. jararaca : Enzymatic activity was detected by measuring the proteoly tic and phos - pholipase A2; macrophages cytotoxicity was determined by the MTT method; levels of cytokine were evaluated using ELISA and a biological assay. After treatment with 300 µg/mL B. xbuttiana extract for 30 min, the proteolytic and phospholipase A2 activities of the venom were reduced to 95 and 61%, respectively. In macrophages cultures treated with B. xbuttiana extract combined with venom, the production of TNF - α, IL - 6 and IFN - γ was reduced, whereas IL - 10 was potenti - ated. Our results support the potential effect of the B. xbuttiana extract as a complementary therapy against the toxicity caused by the venom of B . jararaca snakes

ABSTRACT

SUMMARY: The 12C6+ heavy ion beam irradiation can cause bystander effects. The inflammatory cytokines, endocrine hormones and apoptotic proteins may be involved in 12C6+ irradiation-induced bystander effects. This study characterized the protective effects and mechanisms of Huangqi decoction (HQD) against 12C6+ radiation induced bystander effects. Wistar rats were randomly divided into control, 12C6+ heavy ion irradiation model, and high-dose/medium-dose/low-dose HQD groups. HE staining assessed the pathological changes of brain and kidney. Peripheral blood chemical indicators as well as inflammatory factors and endocrine hormones were detected. Apoptosis was measured with TUNEL. Proliferating cell nuclear antigen (PCNA) expression was determined with real-time PCR and Western blot.Irradiation induced pathological damage to the brain and kidney tissues. After irradiation, the numbers of white blood cells (WBC) and monocyte, and the expression of interleukin (IL)-2, corticotropin-releasing hormone (CRH) and PCNA decreased. The damage was accompanied by increased expression of IL-1β, IL-6, corticosterone (CORT) and adrenocorticotropic hormone (ACTH) as well as increased neuronal apoptosis. These effects were indicative of radiation-induced bystander effects. Administration of HQD attenuated the pathological damage to brain and kidney tissues, and increased the numbers of WBC, neutrophils, lymphocyte and monocytes, as well as the expression of IL-2, CRH and PCNA. It also decreased the expression of IL-1β, IL-6, CORT and ACTH as well as neuronal apoptosis. HQD exhibits protective effects against 12C6+ radiation-induced bystander effects. The underlying mechanism may involve the promotion of the production of peripheral blood cells, inhibition of inflammatory factors and apoptosis, and regulation of endocrine hormones.


La irradiación con haz de iones pesados 12C6+ puede provocar efectos secundarios. Las citoquinas inflamatorias, las hormonas endocrinas y las proteínas apoptóticas pueden estar involucradas en los efectos secundarios inducidos por la irradiación 12C6+. Este estudio caracterizó los efectos y mecanismos protectores de la decocción de Huangqi (HQD) contra los efectos externos inducidos por la radiación 12C6+. Las ratas Wistar se dividieron aleatoriamente en grupos control, modelo de irradiación de iones pesados 12C6+ y grupos de dosis alta/media/baja de HQD. La tinción con HE evaluó los cambios patológicos del cerebro y el riñón. Se detectaron indicadores químicos de sangre periférica, así como factores inflamatorios y hormonas endocrinas. La apoptosis se midió con TUNEL. La expresión del antígeno nuclear de células en proliferación (PCNA) se determinó mediante PCR en tiempo real y transferencia Western blot. La irradiación indujo daños patológicos en los tejidos cerebrales y renales. Después de la irradiación, disminuyó el número de glóbulos blancos (WBC) y monocitos, y la expresión de interleucina (IL)-2, hormona liberadora de corticotropina (CRH) y PCNA. El daño estuvo acompañado por una mayor expresión de IL-1β, IL-6, corticosterona (CORT) y hormona adrenocorticotrópica (ACTH), así como un aumento de la apoptosis neuronal. Estas alteraciones fueron indicativas de efectos inducidos por la radiación. La administración de HQD atenuó el daño patológico a los tejidos cerebrales y renales, y aumentó el número de leucocitos y monocitos, así como la expresión de IL-2, CRH y PCNA. También disminuyó la expresión de IL-1β, IL-6, CORT y ACTH, así como la apoptosis neuronal. HQD exhibe mecanismos protectores contra los efectos externos inducidos por la radiación 12C6+. El mecanismo subyacente puede implicar la promoción de la producción de células sanguíneas periféricas, la inhibición de factores inflamatorios y la apoptosis y la regulación de hormonas endocrinas.

ABSTRACT

@#A 60-year-old Filipino woman diagnosed with dermatomyositis was initially on prednisone and methotrexate. She eventually developed interstitial lung disease (ILD) and so methotrexate was shifted to azathioprine; however, azathioprine was discontinued due to cutaneous tuberculosis. Over eight years, the dermatomyositis was controlled by prednisone alone but the ILD worsened. This case demonstrated that the course of ILD may be independent of dermatomyositis.

ABSTRACT

Immune thrombocytopenia (ITP) is an immune-mediated acquired hemorrhagic autoimmune disease. At present, the first-line therapeutic drugs for ITP include glucocorticoids and intravenous immunoglobulins. However, about 1/3 of the patients had no response to the first-line treatment, or relapsed after dose reduction or withdrawal of glucocorticoids. In recent years, with the gradual deepening of the understanding on the pathogenesis of ITP, the drugs targeting different pathogenesis continually emerge, including immunomodulators, demethylating agents, spleen tyrosine kinase (SYK) inhibitors and neonatal Fc receptor (FcRn) antagonist. However, most of these drugs are in clinical trials. This review summarized briefly the recent advances in the treatment of glucocorticoids resistance and relapsed ITP, so as to provide reference for the clinical treatments.

ABSTRACT

Atypical hemolytic-uremic syndrome (aHUS) is a rare entity characterized by the association of acute kidney failure, thrombocytopenia and microangiopathic hemolytic anemia due to the dysregulation of the alternative pathway of the complement system. It is included within the thrombotic microangiopathies. The following aHUS was developed in the immediate puerperium in the context of severe preeclampsia. The patient was a primiparous woman of 30+1 weeks who required hospitalization for anticonvulsant and hypotensive treatment, and who underwent an emergency cesarean section due to a pathological cardiotocographic pattern. 36 hours after delivery, the patient presented with sudden dyspnea and cognitive deterioration, progressing in a few hours to renal and multiorgan failure. Blood test showed severe anemia, thrombopenia and hypertransaminemia. In view of the fast evolution and severity, it was decided to treat with Eculizumab, although the scientific evidence was very poor. Aside from the supportive treatment performed in the Intensive Care Unit, the patient was successfully treated with Eculizumab, with favorable evolution over the following months and restoration of kidney function, although need for chronic hypotensive treatment remained.


El síndrome hemolítico-urémico atípico (SHUa) es una entidad rara caracterizada por la asociación de insuficiencia renal aguda, trombocitopenia y anemia hemolítica microangiopática debido a la desregulación de la vía alternativa del sistema del complemento. Se incluye dentro de las microangiopatías trombóticas. Se presenta un SHUa que se desarrolló en el puerperio inmediato en el contexto de una preeclampsia grave. La paciente era una primípara de 30+1 semanas que requirió hospitalización para tratamiento anticonvulsivo e hipotensor, y a la que se le practicó una cesárea de urgencia por un patrón cardiotocográfico patológico. A las 36 horas del parto, la paciente presentó una disnea súbita y un deterioro cognitivo progresivo, que evolucionó en pocas horas a un fallo renal agudo y multiorgánico. La analítica mostró anemia severa, trombopenia e hipertransaminemia. Ante la rápida evolución y gravedad, se decidió tratar con Eculizumab, aunque la evidencia científica era escasa. Aparte del tratamiento de soporte realizado en la Unidad de Cuidados Intensivos, la paciente fue tratada con éxito con Eculizumab, con evolución favorable en los meses siguientes y restablecimiento de la función renal, aunque se mantuvo la necesidad de tratamiento hipotensor crónico.

ABSTRACT

Actualmente se estudia la importancia de los estilos de vida sobre el sistema inmunológico. Las infecciones virales respiratorias son una causa de morbimortalidad en el adulto y pueden ocasionar cuadros graves. Una dieta balanceada, el consumo de micronutrientes y el ejercicio, presentan posibles beneficios en la evolución de estas infecciones. Se realizó una revisión narrativa utilizando revisiones bibliográficas y artículos originales obtenidos por PubMed, SciELO, HINARI y Elsevier. Los estudios describen que el consumo de suplementos vitamínicos modula la susceptibilidad a agentes patógenos debido a su actividad antioxidante y permiten el funcionamiento adecuado de la inmunidad innata y adaptativa. Acompañados a ello, los lípidos y los carbohidratos de la dieta son elementos básicos de las células del sistema inmune que, acompañado de 45 minutos de ejercicio moderado, mejoran la respuesta inmune y reducen el riesgo de infecciones virales respiratorias. El consumo de micronutrientes, el ejercicio aeróbico de moderada intensidad y la dieta balanceada son factores que disminuyen la duración de los síntomas por infecciones virales respiratorias agudas en el adulto. Sin embargo, aún se desconoce exactamente el mecanismo de acción del ejercicio en el sistema inmune


The role of lifestyles on the immune system is currently being studied. Respiratory viral infections are a cause of morbidity and mortality in adults, and can cause serious conditions. A balanced diet, consumption of micronutrients and exercise have possible benefits in the evolution of these infections. A narrative review was carried out using bibliographic reviews and original articles obtained in PubMed, SciELO, HINARI and Elsevier. Studies describe that the consumption of vitamin supplements modulates the susceptibility to pathogens due to their antioxidant activity and allows the proper functioning of innate and adaptive immunity. Along with this, lipids and carbohydrates in the diet are basic elements of the immune system cells and, accompanied with 45 minutes of moderate exercise, improve the immune response and reduce the risk of respiratory viral infections. The consumption of micronutrients, moderate intensity aerobic exercise and a balanced diet, are factors that decrease the duration of symptoms due to acute respiratory viral infections in adults. However, the exact mechanism of action of exercise on the immune system is still unknown

ABSTRACT

Introducción: El trasplante es la opción terapéutica más favorable para las personas con insuficiencia renal crónica. El donante puede ser cadavérico o donante vivo, emparentado o no. Los resultados del trasplante están en relación con varios factores inmunológicos y no inmunológicos. Objetivo: Caracterizar inmunogenéticamente a los donantes cadavéricos cubanos para trasplante renal. Métodos: Se realizó un estudio transversal y descriptivo de los donantes cadavéricos durante el año 2019. Se analizó la región de procedencia, sexo, color de la piel y rangos de edades de los donantes, así como, grupo sanguíneos ABO y Rhesus Rh; serología para VIH, Virus de hepatitis B(VHB) y Virus de hepatitis C (VHC); y hábitos tóxicos. Resultados: Se estudió un total de 95 donantes cadavéricos, 62 provenientes del occidente y 33 del centro del país. El 63,2 por ciento fueron masculinos y 36,8 por ciento femenino. El grupo de edad de mayor frecuencia fue 40 - 60 años y la edad media de 49,45 años. El 58,95 por ciento de los pacientes fueron de grupo sanguíneo O; 30,53 por ciento grupo A y los grupos B y AB tuvieron 5,26 por ciento de prevalencia; y solo 8 fueron Rh negativos. Todos tuvieron serología para VIH, VHB y VHC negativas. Las enfermedades asociadas más frecuentes fueron la hipertensión arterial y la diabetes mellitus. Conclusiones: Los donantes cadavéricos durante el año 2019 mostraron características similares a las reportadas por otros estudios. El aumento de las edades de los donantes incide en la aparición de enfermedades asociadas y esto pudiera repercutir en el resultado del trasplante(AU)


Introduction: Transplantation is the most favorable therapeutic option for people with chronic renal failure. The donor can be a cadaveric or living donor, related or not. Transplant outcomes are related to various immunological and non-immunological factors. Objective: To characterize Cuban cadaveric donors for renal transplantation Materials and methods: A cross-sectional and descriptive study of cadaveric donors was carried out during the year 2019. The region of origin, sex, skin color and age ranges of the donors were analyzed, as well as ABO and Rhesus Rh blood groups; serology for HIV, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV), and toxic habits. Results: A total of 95 cadaveric donors were studied, 62 from the West and 33 from the Center of the country. 63.2 percent were male and 36.8 percent female due to the most frequent age group being 40-60 years and the mean age of 49.45 years. 58.95 percent of the patients were of blood group O, 30.53 percent group A and groups B and AB had 5.26 percent prevalence; and only 8 were Rh negative. All had negative serology for HIV, HBV and HCV. The most frequent associated diseases were arterial hypertension and diabetes mellitus. Conclusions: The cadaveric donors during the year 2019 showed characteristics similar to those reported by other studies. The increase in the age of the donors affects the appearance of associated diseases and this could affect the result of the transplant(AU)

ABSTRACT

El término miocarditis hace referencia a una inflamación del miocardio, que puede tener diversas causas (infecciones, tóxicos, enfermedades autoinmunes). Su diagnóstico es desafiante debido al gran espectro de presentaciones clínicas que puede adoptar, muchas veces imitando patologías más prevalentes como el infarto agudo de miocardio. La miocarditis asociada a enfermedades autoinmunes es poco frecuente, y la importancia de reconocerla radica en que el diagnóstico e inicio temprano del tratamiento son cruciales para mejorar su pronóstico. Presentamos aquí un caso clínico de una perimiocarditis lúpica.


Myocarditis refers to an inflammation of the myocardium, which can have various causes (infections, toxic substances, autoimmune diseases). Its diagnosis is challenging due to the wide spectrum of clinical presentations, often mimicking more prevalent pathologies such as acute myocardial infarction. Myocarditis associated with autoimmune diseases is rare, and the importance of recognizing is that early diagnosis and initiation of treatment are crucial to improve its prognosis. We present here a clinical case of lupus perimyocarditis.


O termo miocardite refere-se a uma inflamação do miocárdio, que pode ter várias causas (infecções, substâncias tóxicas, doenças autoimunes). Seu diagnóstico é desafiador devido ao amplo espectro de apresentações clínicas que pode ter, muitas vezes mimetizando patologias mais prevalentes como o infarto agudo do miocárdio. A miocardite associada a doenças autoimunes é rara, e a importância de reconhecê-la reside no fato de que o diagnóstico precoce e o início do tratamento são cruciais para melhorar seu prognóstico. Apresentamos aqui um caso clínico de perimiocardite lúpica.

ABSTRACT

Small cell lung cancer is a kind of malignant tumor with strong invasiveness and poor prognosis, and the classic therapeutic modality of the disease remains multidisciplinary and comprehensive treatment. Treatment options for small cell lung cancer have been stalled for a long time, and new opportunities have emerged in recent years due to the development and initial experience of immunotherapeutic drugs. Clinical trials of some selected immune checkpoint inhibitors have confirmed the efficacy and safety in small cell lung cancer. Based on the results of phase III clinical trials (Impower133 and CASPIAN), Atezolizumab or Durvalumab in combination with chemotherapy has been approved by the U.S. Food and Drug Administration for the first-line treatment of extensive-stage small cell lung cancer. Clinical trials involving immune checkpoint inhibitors are being actively carried out and provide different perspectives for the management of small cell lung cancer. This article aimed to review the clinical progress in immunotherapy of small cell lung cancer.

ABSTRACT

OBJECTIVES@#There is less clinical data on multiple myeloma (MM) in China, and the aim of this study was to collect and analyze the clinical data of newly diagnosed multiple myeloma (NDMM) patients in Hunan Province during 1 year, to understand the real clinical features and treatment outcome for Hunan Province patients with MM, and to strengthen the understanding of the standardized diagnosis process and treatment plan of MM.@*METHODS@#The clinical data of 529 patients with NDMM in 12 large-scale general hospitals in Hunan Province from January 1 to December 31, 2019 were collected and analyzed, including baseline data, treatment regimens, duration of treatment, and adverse reactions. The clinical characteristics, treatment, and safety of patients were analyzed by SPSS 21.0.@*RESULTS@#Among the 529 NDMM patients, the age was 33-90 (median 64) years and the male-female ratio was 1.38꞉1. The clinical features ranged from high to low were as follows: Bone pain (77.7%), anemia (66.8%), renal insufficiency (40.6%), hypercalcemia (15.1%). Typing: IgG 46.5%, IgA 24.6%, IgD 2.6%, IgM 0.8%, light chain 15.7%, double clone 3.0%, no secretion 0.6%, absence 6.2%. Staging: Durie-Salmon stage I, II, and III were 4.5%, 10.6%, 77.3%, respectively, and 40 cases (7.6%) missed this data. International Staging System (ISS) stage I, II, and III were 10.4%, 24.4%, and 47.6%, respectively, and 93 cases (17.6%) were missing. Revised International Staging System (R-ISS) stage I, II, and III were 5.5%, 27.0%, 23.1%, respectively, and 235 cases (44.4%) missed this data. Among the 98 NDMM patients in the Third Xiangya Hospital, Central South University, Durie-Salmon (DS) stage missing 2.0%, ISS stage missing 12.3%, and R-ISS stage missing 12.3%.Treatment: Among the 529 patients,475 received treatment, the rate of treatment was 89.8%; 67.4% of the patients were able to complete four courses of chemotherapy at induction phase, 90.3% of the patients received proteasome inhibitor based combination chemotherapy regimen more than once, 67.2% received immunomodulator based regimen more than once, and 59.8% of the patients received proteasome inhibitor and immunomodulator based combination chemotherapy regimen more than once. Curative: Overall response rate (ORR) and high quality response rate (HQR) of the 4-course group were better than those of the 2-course group (ORR: 85% vs 65%, P=0.006; HQR: 68.3% vs 24.0%, P<0.001). The HQR of the standard chemotherapy group was better than that of the non-standard chemotherapy group (65.1% vs 48.2%, P=0.035). Adverse reactions during treatment included hematologic toxicity (17.5%), peripheral neuropathy (24.8%), gastrointestinal adverse events (23.8%), pulmonary infection (25.9%), herpes zoster (4.6%), and venous thrombotic events (1.7%).@*CONCLUSIONS@#In 2019, the missed diagnosis rate of MM patients was high, the medium age of diagnosis was older, and the accuracy of patient diagnosis was not high. There is a great difference among medical centers, especially in the stage and risk stratified, nearly half of NDMM patients are not diagnosed with R-ISS stage; the lack of cytogenetic data needs to be supplemented by follow-up studies. A high proportion of patients with NDMM present with bone pain and anemia.Patients received treatment have higher use of chemotherapy regimens containing proteasome inhibitors and/or immunomodulators, but there is a significant gap among different medical centers, and standardized treatment needs to be strengthened. The safety during chemotherapy is controllable.

ABSTRACT

Immune checkpoint inhibitors have progressed rapidly over the past decade and have become one of the most promising oncology treatments. However, immune checkpoint inhibitors reduce T-cell tolerance and lead to a unique spectrum of immune-related adverse events (IRAE). IRAE can involve multiple systems, including endocrine, gastrointestinal, respiratory and skin systems and there is no predictive marker with high specificity and sensitivity. Mild IRAE can be alleviated by discontinuing immune checkpoint inhibitors while severe IRAEs require active intervention. The first-line treatment is glucocorticoids, and immunosuppressants can be considered in refractory cases. However the optimal choice of immunosuppressants is currently controversial. This review provides an overview of the epidemiology and possible mechanisms of immune-related adverse events, outlines some promising predictive biomarkers, and describes several immunotherapy-related organ toxicity and management.

ABSTRACT

Purpose: To explore the potential immunomodulatory effects of total extract and different polar parts from Blaps rynchopetera Fairmaire. Methods: Phagocytic activity was evaluated by neutral red assay, and the effect of the immune function was investigated by normal and immunocompromised mice models. Results: In vitro, total extract, as well as chloroform, ethyl acetate, n-butanol and water fractions could individually enhance the phagocytic ability of mouse peritoneal macrophages; in addition, chloroform and ethyl acetate fractions had an increasing tendency when combined stimulation with lipopolysaccharide (LPS). In vivo, ethyl acetate fraction (EAF) could enhance the immune organ index, increase the serum hemolysin level and peripheral blood immune cells of immunocompromised mice, while for normal mice, the effect was inconspicuous. Conclusions: Blaps rynchopetera extracts had noteworthy immunomodulatory effect, especially for individuals with immune disorders.

ABSTRACT

En Uruguay, la pandemia por SARS-CoV-2 ha generado menos afectación en pacientes de la edad pediátrica, aumentando el número de casos positivos en este grupo etario de forma proporcional al aumento de la circulación del virus. La forma de presentación es generalmente asintomática o con síntomas respiratorios leves a moderados. El síndrome inflamatorio multisistémico postinfección por SARS-CoV-2 (SIM-C) ha sido descrito como una de las principales complicaciones postinfección. Se describe el primer caso de un paciente con SIM-C en la ciudad de Paysandú, Uruguay. Se trata de un escolar de 6 años que cursó una infección por SARS-CoV-2 un mes previo. Se presenta con un cuadro febril de 4 días de evolución asociado a lesiones de piel e inyección conjuntival y odinofagia, con parámetros inflamatorios elevados y afectación cardiológica. Se traslada a CTI local con buena evolución posterior. El alto índice de sospecha de SIM-C mejora el diagnóstico y en consecuencia la morbimortalidad de la enfermedad.


Summary: In Uruguay, the SARS-CoV-2 pandemic has affected the pediatric population less and the number of positive cases in this age group has increased proportionally to the rise of the virus circulation. The presentation is generally asymptomatic or with mild to moderate respiratory symptoms. Post-Infection Multisystem Inflammatory Syndrome by SARS-CoV-2 (MIS-C) has been described as one of the main post-infection complications. We describe the first case of a patient with MIS-C in the city of Paysandú, Uruguay. It is a 6-year-old schoolboy who had had a SARS-CoV-2 infection a month earlier. He showed a 4-day history of fever associated with skin lesions and conjunctival injection and odynophagia, with high inflammatory parameters and cardiac involvement. He was transferred to a local ICU and had a good subsequent evolution. The high index of suspicion of MIS-C improves the diagnosis and consequently the morbidity and mortality rates of the disease.

A forma de apresentação é geralmente assintomática ou com sintomas respiratórios leves a moderados. A Síndrome Inflamatória Multissistêmica Pós-Infecção por SARS-CoV-2 (MIS-C) tem sido descrita como uma das principais complicações pós-infecção. Descreve-se o primeiro caso de paciente com MIS-C na cidade de Paysandú, Uruguai. Ele é um estudante de 6 anos de idade que tinha tido uma infecção por SARS-CoV-2 um mês antes. Apresentou história de febre de 4 dias associada a lesões cutâneas e hiperemia conjuntival e odinofagia, com parâmetros inflamatórios elevados e envolvimento cardiológico. Foi transferido para uma UTI local com boa evolução posterior. O alto índice de suspeita de MIS-C melhora o diagnóstico e, consequentemente, a morbimortalidade da doença.

ABSTRACT

En abril de 2020, durante el pico de la pandemia COVID-19 producida por el coronavirus emergente SARS-CoV-2, en el Reino Unido se comunicaron casos de shock hiperinflamatorio de características similares a la enfermedad de Kawasaki y el síndrome de shock tóxico en un grupo de ocho niños. El Royal College of Pediatrics and Child Health lo denominó síndrome inflamatorio multisistémico pediátrico temporalmente asociado con COVID-19 (SIM-C). Actualmente, el SIM-C es una enfermedad infrecuente, solapada con otras entidades, que requiere una alta sospecha clínica para identificarlo oportunamente. El síndrome inflamatorio multisistémico temporal asociado con SARS-CoV-2 pediátrico (PIMST) es una nueva entidad clínica con un amplio espectro de presentación postexposición al virus, inmunomediado con hiperinflamación y activación de una tormenta de citoquinas. Ocurre típicamente entre la segunda y cuarta semana de evolución. Se describen marcadores de inflamación característicamente elevados, como son la ferritina, proteína C reactiva (PCR), velocidad de eritrosedimentación (VES), lactato deshidrogenasa y dímero-D, asociados a neutropenia, linfopenia y anemia. La Organización Mundial de la Salud (OMS) define: caso a menores de 19 años con fiebre ≥3 días, marcadores inflamatorios elevados, evidencia de infección por SARS-CoV-2 y ninguna otra etiología microbiana; con afectación de al menos dos sistemas: dermatológico (rash, conjuntivitis no exudativa, inflamación mucocutánea), hemodinámico (hipotensión, shock), cardíaco (disfunción de miocardio, pericardio, valvular o coronario), hematológico (coagulopatía), digestivo (vómitos, diarrea, dolor abdominal). Considerando la gravedad de esta nueva entidad, es necesario el reconocimiento oportuno y referencia temprana para atención especiaizada y tratamiento oportuno.


Summary: In April 2020, during the peak of the COVID-19 pandemic caused by the emerging coronavirus SARS-CoV-2, 8 children reported cases of hyperinflammatory toxic shock with characteristics similar to Kawasaki disease and syndrome in the United Kingdom. The Royal College of Pediatrics and Child Health has called it pediatric Multisystem Inflammatory Syndrome (MIS) temporally associated with COVID-19. Currently, MIS-C is a rare disease, overlapping with other conditions, which requires a high clinical suspicion for its timely identification. Pediatric SARS-CoV-2-associated temporary multisystem inflammatory syndrome (TMIS-C) is a new clinical entity with a broad spectrum of presentation after exposure to the virus, immune-mediated with hyperinflammation and activation of a cytokine storm. It typically occurs between the 2nd to 4th week of evolution. Characteristically elevated markers of inflammation are described, such as ferritin, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), lactate dehydrogenase and D-dimer, associated with neutropenia, lymphopenia and anemia. The World Health Organization (WHO) defines it as: a case under 19 years of age with fever ≥ 3 days, elevated inflammatory markers, evidence of SARS-CoV-2 infection and no other microbial etiology; with involvement of at least 2 systems: dermatological (rash, non-exudative conjunctivitis, mucocutaneous inflammation), hemodynamic (hypotension, shock), cardiac (myocardial, pericardial, valvular, or coronary dysfunction), hematologic (coagulopathy), digestive (vomiting, diarrhea, abdominal pain) Considering the seriousness of this new entity, timely recognition and early referral for specialized care and timely treatment are key.


No mês de abril de 2020, durante o pico da pandemia de COVID-19 causada pelo emergente coronavírus SARS-CoV-2, 8 casos de crianças com choque hiperinflamatório com características semelhantes à doença e síndrome de Kawasaki foram relatados no Reino Unido. O Royal College of Pediatrics and Child Health nomeou-o como síndrome inflamatória multissistêmica pediátrica (MIS) temporariamente associada ao COVID-19. Atualmente, o SIM-C é uma doença rara, sobrepondo-se a outras entidades, o que requer alta suspeição clínica para sua identificação oportuna. A síndrome inflamatória multissistêmica temporária associada ao SARS-CoV-2 pediátrico (SIMT) é uma nova entidade clínica com amplo espectro de apresentação após exposição ao vírus, imunomediada com hiperinflamação e ativação de uma tempestade de citocinas. Geralmente ocorre entre a 2ª a 4ª semana de evolução. São descritos marcadores de inflamação caracteristicamente elevados, como ferritina, proteína C reativa (PCR), velocidade de hemossedimentação (VHS), lactato desidrogenase e D-dímero, associados a neutropenia, linfopenia e anemia. A Organização Mundial da Saúde (OMS) a define como: caso de menor de 19 anos com febre ≥ 3 dias, marcadores inflamatórios elevados, evidência de infecção por SARS-CoV-2 e nenhuma outra etiologia microbiana; com envolvimento de pelo menos 2 sistemas: dermatológico (erupção cutânea, conjuntivite não exsudativa, inflamação mucocutânea), hemodinâmica (hipotensão, choque), cardíaca (disfunção miocárdica, pericárdica, valvar ou coronariana), hematológica (coagulopatia), digestiva (vômitos, diarreia, dor abdominal) Considerando a gravidade dessa nova entidade, é necessário o reconhecimento oportuno e encaminhamento precoce para atendimento especializado e tratamento oportuno.
