ABSTRACT
Los niños cursan mayormente la infección por el virus SARS-CoV-2 en forma leve. Sin embargo, de forma muy infrecuente algunos pueden desarrollar una patología con marcada gravedad denominada síndrome inflamatorio multisistémico en niños relacionado temporalmente con COVID-19 (SIM-C). Dado su reciente surgimiento, aún hay aspectos de su fisiopatología que se desconocen. La posibilidad de recidiva en caso de reinfección o ante la vacunación contra SARS-CoV-2 son nuevos interrogantes a los que nos enfrentamos. Reportamos una serie de casos de 4 pacientes adolescentes que cursaron SIM-C y meses después han sido vacunados contra SARS-CoV-2 con plataformas ARN mensajero (ARNm) sin presentar recurrencia de la enfermedad ni efectos adversos cardiológicos
In most cases, children with SARS-CoV-2 have a mild infection. However, very rarely, some children may develop a severe disease called multisystem inflammatory syndrome in children temporally associated with COVID-19 (MIS-C). Given its recent emergence, some aspects of its pathophysiology are still unknown. The possibility of recurrence in case of reinfection or SARS-CoV-2 vaccination are new questions we are facing. Here we report a case series of 4 adolescent patients who developed MIS-C and, months later, received the SARS-CoV-2 vaccine with messenger RNA (mRNA) platforms without disease recurrence or cardiac adverse events.

RESUMEN Se presenta el caso de un adolescente masculino, de 15 años, que ingresa por Guardia por dolor abdominal y fiebre de una semana de evolución con RT PCR negativa bajo el diagnóstico presuntivo de apendicitis aguda, que se descarta tras estudios complementarios, y se realiza diagnóstico de síndrome inflamatorio multisistémico asociado a infección por COVID-19.
ABSTRACT We report the case of a 15-year-old adolescent male patient who was admitted to the emergency department due to abdominal pain and fever that started one week before, with negative RT-PCR. The suspected diagnosis was acute appendicitis that was ruled out with complementary tests. The final diagnosis was multisystem inflammatory syndrome associated with COVID-19.
ABSTRACT
Abstract The pathophysiology of multisystem inflammatory syndrome in children (MIS-C) and associated oral symptoms have not been clarified yet. The aim of the present study was to compare the oral health status of children with MIS-C-associated Coronavirus disease 2019 (COVID-19) and COVID-19. A total of 54 children with SARS-CoV-2 infection, 23 with MIS-C-associated COVID-19 and 31 with asymptomatic, mild, and moderate COVID-19 were recruited for the present cross-sectional study. Sociodemographic variables, medical examinations, oral hygiene habits, and extraoral and intraoral findings (DMFT/dmft index, OHI scores, and oral mucosal changes) were recorded. The t-test for independent samples and the Mann-Whitney U test were used (p < 0.05). MIS-C was found to be associated with chapped lips (all patients) and oral mucosal changes, including erythema, white lesion, strawberry tongue, and swelling of the gingiva as compared to the COVID-19 group (frequency of more than one mucosal change: 100% vs. 35%) (p < 0.001). Children with MIS-C presented higher DMFT/dmft scores (DMFT/dmft 5.52 ± 3.16 for the MIS-C group vs. 2.26 ± 1.80 for the COVID-19 group) (p < 0.01). Elevated OHI scores were also associated with MIS-C (mean ± SD: 3.06 ± 1.02 (MIS-C) vs. 2.41 ± 0.97 (COVID-19) (p < 0.05). Oral manifestations, mainly strawberry and erythematous tongue, were characteristic features of MIS-C. Prevalence of oral/dental symptoms was elevated in children with MIS-C when compared to COVID-19. Therefore, dental professionals should be aware of the oral manifestations associated with MIS-C, which may have high mortality and morbidity rates.
ABSTRACT
Abstract Objective: This study aimed to describe the clinical characteristics and the different phenotypes of children with multisystem inflammatory syndrome in children (MIS-C) temporally related to COVID-19 and to evaluate the risk conditions that favored a greater severity of the disease during a 12-month period at a pediatric reference hospital in Colombia. Methods: A 12-month retrospective observational study of children under the age of 18 years who met criteria for MIS-C. Results: A total of 28 children presented MIS-C criteria. The median age was 7 years. Other than fever (100%) (onset 4 days prior to admission), the most frequent clinical features were gastrointestinal (86%) and mucocutaneous (61%). Notably, 14 (50%) children had Kawasaki-like symptoms. The most frequent echocardiographic abnormalities were pericardial effusion (64%), valvular involvement (68%), ventricular dysfunction (39%), and coronary artery abnormalities (29%). In addition, 75% had lymphopenia. All had at least one abnormal coagulation test. Most received intravenous immunoglobulin (89%), glucocorticoids (82%), vasopressors (54%), and antibiotics (64%). Notably, 61% had a more severe form of the disease and were admitted to an intensive care unit (median 4 days, mean 6 days); the severity predictors were patients with the inflammatory/MIS-C phenotype (OR 26.5; 95%CI 1.40-503.7; p=0.029) and rash (OR 14.7; 95%CI 1.2-178.7; p=0.034). Two patients had macrophage activation syndrome. Conclusions: Coronary artery abnormalities, ventricular dysfunction, and intensive care unit admission were frequent, which needs to highlight the importance of early clinical suspicion.
Resumo Objetivo: Descrever as características clínicas e os diferentes fenótipos de crianças com síndrome inflamatória multissistêmica na criança temporalmente relacionada com a COVID-19 (do inglês multisystem inflammatory syndrome in children — MIS-C) e avaliar as condições de risco que favorecem a maior gravidade da doença durante um período de 12 meses em um hospital pediátrico de referência na Colômbia. Métodos: Estudo retrospectivo de 12 meses de observação de crianças menores de 18 anos que cumprem os critérios para o MIS-C. Resultados: Vinte e oito crianças foram apresentadas com os critérios do MIS-C. A idade média era de sete anos, e 54% eram do sexo masculino. Para além da febre (100%) (com início quatro dias antes da admissão), as características clínicas mais frequentes eram gastrointestinais (86%) e mucocutâneas (61%). Quatorze crianças (50%) apresentavam sintomas semelhantes aos de Kawasaki. As anomalias ecocardiográficas mais frequentes foram derrame pericárdico (64%), envolvimento valvar (68%), disfunção ventricular (39%) e anomalias coronárias (29%). Tinham linfopenia 75% das crianças. Todas tinham algum teste de coagulação anormal. A maioria recebeu imunoglobulina intravenosa (89%), glucocorticoides (82%), vasopressores (54%) e antibióticos (64%). Tiveram envolvimento mais grave 61% dos pacientes, que precisaram ser internados em unidade de terapia intensiva (mediana de quatro dias, média de seis dias); os preditores de gravidade foram pacientes com fenótipo inflamatório/ MIS-C (odds ratio — OR 26,5; intervalo de confiança — IC95% 1,4-503,7; p=0,029) e erupção cutânea (OR 14,7; IC95% 1,2-178,7; p=0,034). Dois pacientes (7%) apresentavam síndrome de ativação macrofágica. Conclusões: Alteração da artéria coronária, disfunção ventricular e internação na unidade de terapia intensiva foram frequentes, o que nos alerta sobre a importância da suspeita clínica precoce.
ABSTRACT
Background & objectives: There are limited data from India on the post-COVID multisystem inflammatory syndrome in adults (MIS-A). The objective of the present study was to evaluate the clinical profile of patients with MIS-A admitted to a tertiary care centre in southern India. Methods: This single-centre retrospective study was conducted from November 2020 to July 2021, and included patients aged >18 yr admitted to the hospital as per the inclusion and exclusion criteria. Results: Nine patients (5 male, mean age 40±13 yr) met the criteria for MIS-A. Five patients had proven COVID-19 infection or contact history 36.8±11.8 days back. All patients were positive for SARS-CoV-2 IgG antibody, negative for COVID-19 PCR, and had negative blood, urine and sputum cultures. All patients had fever and gastrointestinal (GI) symptoms, and five patients had left ventricular dysfunction. All patients had neutrophilic leucocytosis at presentation and elevated biomarkers such as C-reactive protein serum procalcitonin, D-dimer and ferritin. The majority of the patients (7/9 i.e. 77.78%) were treated with intravenous hydrocortisone (50-100 mg q6h-q8h). Six patients recovered completely whereas three patients expired. Interpretation & conclusions: Fever and GI symptoms were the most common presentation of MIS-A. Elevated serum procalcitonin may not be useful in differentiating bacterial sepsis from MIS-A. Most patients responded to corticosteroids.
ABSTRACT
The novel coronavirus disease (COVID-19) caused by SARS-CoV-2 has turned the world topsy-turvy since its emergence. Although COVID-19 is mostly associated with respiratory pathology, it can also result in several extrapulmonary manifestations. Multisystem Inflammatory Syndrome in Adults (MIS-A) seems to be a new addition to the ever expanding COVID-19 puzzle and warrants extensive research to familiarize the phenotype, formulate a definitive treatment and prognosticate accordingly. This article highlights the case definition, pathogenesis, clinical features and treatment modalities of this new entity with a concise review of available literature at present.
ABSTRACT
Introducción: un caso de rabdomiólisis severa asociado a síndrome inflamatorio multisistémico asociado a COVID -19 (MIS-C). Reporte de caso: en un niño de 1 año 10 meses que presentó síntomas digestivos, mialgias, debilidad, fiebre y orina oscura. Prueba serológica COVID-19 IgM (-) IgG (+), PCR COVID-19 negativo. Creatin-quinasa (CK) inicial fue no dosable, siendo el nivel reportado más alto de 517 600 U/L. El valor de creatinina se mantuvo normal durante toda la hospitalización. Recibió Inmunoglobulina humana 2 g/Kg, Metilprednisolona 10 mg/Kg/d y ácido acetil salicílico para manejo de MIS-C. Se brindó hidratación enérgica y alcalinización de orina para manejo de rabdomiólisis. Conclusión: Evolución favorable con alta luego de diez días. Existen pocos casos reportados de rabdomiólisis asociados a MIS-C, y ninguno con valores tan altos de CK. En base a las posibles complicaciones se sugiere realizar dosaje de CK de forma rutinaria en todos los pacientes con MIS-C.
Introduction: A case of severe rhabdomyolysis associated with multisystem inflammatory syndrome related to COVID-19 (MIS-C). Case of report: is presented in a one-year 10-month-old boy who presented digestive symptoms, myalgia, weakness, fever, and dark urine. COVID-19 IgM (-) IgG (+) serological test, COVID-19 PCR negative. Initial creatine kinase (CK) presented non-dosable values, with the highest reported level being 517,600 U/L. The creatinine value remained normal throughout the hospitalization. He received human immunoglobulin 2 g/Kg, Methylprednisolone 10 mg/Kg/d, and acetylsalicylic acid to manage MIS-C. Aggressive hydration and urine alkalinization were provided to manage rhabdomyolysis. Conclusion: Positive evolution with discharge after ten days. Few reported cases of rhabdomyolysis are associated with MIS-C and none with such high CK values. Based on the possible complications, performing CK dosing in all patients with MIS-C is suggested routinely.
ABSTRACT
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy may increase the risk of stillbirth, neonatal death, preterm birth, low birth weight, fetal distress, and neonatal asphyxia. Vertical transmission of SARS-CoV-2 is under investigation. Afew reports suggest the possibility of SARS-CoV-2 transmission from mothers to their neonates. The SARS-CoV-2 virus was reported as one of the rare causes of fetal inflammatory response syndrome (FIRS) and is associated with multisystem inflammatory syndrome in children (MIS-C).
ABSTRACT
Objective: To determine the clinical presentation and outcome of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the third wave of the pandemic in India. Method: A review of hospital records was done at a tertiary care hospital, for children seen between 1 and 25 January, 2022. Result: Out of total 112 SARS-CoV-2 positive patients, 17 were hospitalized and 95 were treated in the outpatient department. Among non-hospitalized children, fever was the commonest feature (72, 75.7%), followed by sneezing, and loss of appetite. The median (IQR) duration of symptoms was 2.5 (1.5) days. Among hospitalized children, 10 had co-morbidities and one-third required intensive care unit admission. MIS-C was diagnosed in four patients. Out of 4 mechanically ventilated patients, two had coronavirus disease (COVID) pneumonia. The mean (SD) length of hospital stay was 7.5 (2.5) days. One child with leukemia died during management. Conclusion: During the third wave of the pandemic, most children had symptomatic illnesses, but recovery was fast among non-hospitalized children.
ABSTRACT
Multisystem inflammatory syndrome in children is a serious condition that occurs due to postinfectious immune-mediated hyperinflammatory reaction seen in children, which develops after 4–6 weeks of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection; it is rare in neonates. We present here a case of a term newborn with fever, respiratory distress, and necrotic skin lesion that gradually progressed to multisystem dysfunction. Reverse transcription polymerase chain reaction for SARS-CoV-2 was negative for both mother and the baby. SARS-CoV-2 IgG titer was negative in the mother but was found to be positive in the newborn. The diagnosis of multisystem inflammatory syndrome in neonate was made and was successfully treated with intravenous immunoglobulin and corticosteroids.
ABSTRACT
Resumen Introducción: Existen pocos reportes de síndrome de dificultad respiratoria aguda (SDRA) con COVID-19 en pacientes pediátricos. El objetivo de este estudio fue describir las características de los pacientes pediátricos críticamente enfermos con COVID-19, la frecuencia del SDRA, la mecánica ventilatoria y los resultados de la posición prona. Métodos: Se llevó a cabo un estudio retrospectivo y observacional de los pacientes ingresados del 1 de abril al 30 de septiembre de 2020. Resultados: Ingresaron 34 pacientes a la unidad de terapia intensiva pediátrica (UTIP) con prueba positiva para SARS-CoV-2. De ellos, 13 presentaron SDRA, 11 requirieron ventilación mecánica invasiva y siete fueron pronados como estrategia de oxigenación. Todos los pacientes clasificados como SDRA graves fueron pronados. La obesidad fue la comorbilidad más importante. Las complicaciones asociadas con SDRA fueron el síndrome inflamatorio multisistémico (p < 0.05) y la lesión renal aguda (p < 0.05). La procalcitonina fue mayor en los pacientes con SDRA, al igual que los días de estancia en la UTIP (p < 0.05). El éxito de la maniobra de pronación se alcanzó 8 horas después.Los resultados observados fueron los siguientes relación presión arterial de oxígeno/fracción inspirada de oxígeno 128 vs. 204, índice de oxigenación 8.9 vs. 5.9, distensibilidad pulmonar estática 0.54 vs. 0.70 ml/cmH2O/kg, y presión meseta 24 vs. 19 cmH2O (p < 0.05). El uso de narcóticos fue mayor en el grupo de SDRA más pronación que en los no pronados (124 vs. 27 h; p < 0.01). La mortalidad asociada con SARS-CoV-2 fue del 5.8%. Conclusiones: El SDRA se presentó en el 38.2% de los niños admitidos a UTIP, y con mayor frecuencia en los pacientes con obesidad. La maniobra de pronación aplicada en los casos severos, mejoró la oxigenación de la mécanica pulmonar. Ninguno de los pacientes falleció por SDRA.
Abstract Background: There are only a few reports of acute respiratory distress syndrome (ARDS) in patients with SARS-CoV-2 in pediatrics. This study aimed to describe the characteristics of critically ill pediatric patients with COVID-19, the frequency of ARDS, ventilatory mechanics and results of prone position. Methods: We conducted a retrospective, observational study of patients admitted to the pediatric intensive care unit (PICU) between April 1 to September 30, 2020. Results: Thirty-four patients were admitted to pediatric intensive care unit, 31.7% were SARS-CoV-2 positive. 13 presented ARDS, 11 required invasive mechanical ventilation, and seven were pronated as an oxygenation strategy. All patients classified as severe ARDS were pronated. Obesity was the most important comorbidity. The complications associated with ARDS were multisystemic inflammatory syndrome (8 vs. 4; p < 0.05) and acute kidney injury (8 vs. 3; p < 0.05). Procalcitonin was higher in patients with ARDS, as were the days of stay in PICU (p < 0.05). The success of the pronation maneuver was achieved 8 hours later , with the following results: arterial oxygen partial pressure to fractional inspired oxygen ratio 128 vs. 204, oxygenation index 8.9 vs. 5.9, static lung compliance 0.54 vs. 0.70 ml/cmH2O/kg, plateau pressure 24 vs. 19 cmH2O (p < 0.05). The use of narcotics was higher in the group with ARDS plus pronation 124 vs. 27 hours in the non-pronated (p < 0.01). Mortality associated with SARS-CoV-2 was 5.8%. Conclusions: ARDS was presented in 38.2% of the children admitted to PICU and was more frequent in obese patients. Pronation, performed in severe cases, improved oxygenation and lung mechanics indexes. No patient died of ARDS.
ABSTRACT
Introducción. La evidencia actual indica que la gravedad de la enfermedad por el coronavirus 2019 (COVID-19, por su sigla en inglés) es menor en la población pediátrica, los datos locales aún son limitados. Objetivo: caracterizar los aspectos clínicos y epidemiológicos de la infección por COVID-19 en menores de 18 años en Argentina. Población y métodos. Estudio transversal, observacional y analítico de casos confirmados de COVID-19 entre 0 y 18 años asistidos entre marzo de 2020 y marzo de 2021 en 19 centros pediátricos de referencia de Argentina. Se realizó un análisis multivariado para identificar las variables predictoras de cuadros graves. Resultados. Se incluyeron 2690 casos de COVID-19: 77,7 % residentes del área metropolitana de Buenos Aires, 50,1 % de sexo masculino, mediana de edad de 5,6 años. El 90 % ocurrió entre las semanas epidemiológicas 20-47 del 2020; 60,4 % con antecedente de contacto con personas con COVID-19; y 96,6 % en el entorno familiar. El 51,4 % presentó síntomas respiratorios; 61,6 % síntomas generales; 18,8 % síntomas gastrointestinales; 17,1 % síntomas neurológicos; 7,2 % otros y 21,5 % fueron asintomáticos. El 59,4 % fue hospitalizado; 7,4 fueron graves o críticos. Se registraron 57 casos de síndrome inflamatorio multisistémico. El antecedente de asma, displasia broncopulmonar, cardiopatía congénita, desnutrición moderada a grave, obesidad, enfermedad neurológica crónica y/o edad menor de 6 meses resultaron predictores independientes de gravedad. Residir en barrios vulnerables resultó protector. Conclusiones. Más de la mitad de los casos refirieron antecedente de contacto con personas con COVID-19 en el entorno familiar. La hospitalización no respondió a criterios clínicos de gravedad. La gravedad se encuentra asociada a la existencia de ciertas comorbilidades.
Introduction. The current evidence indicates that the severity of the coronavirus disease 2019 (COVID-19) is lower in the pediatric population but local data are still limited. Objective: To characterize the clinical and epidemiological aspects of COVID-19 infection in patients younger than 18 years in Argentina. Population and methods. Cross-sectional, observational, and analytical study of confirmed COVID-19 patients aged 0-18 years seen between March 2020 and March 2021 at 19 referral children's hospitals of Argentina. A multivariate analysis was done to identify predictors of severe cases. Results. A total of 2690 COVID-19 cases were included: 77.7% lived in the Metropolitan Area of Buenos Aires; 50.1% were males; patients' median age was 5.6 years. Of them, 90% were seen during epidemiological weeks 20-47 of 2020; 60.4% had a history of contact with COVID-19 patients; and 96.6% in their family setting. Also, 51.4% had respiratory symptoms; 61.6%, general symptoms; 18.8%, gastrointestinal symptoms; 17.1%, neurological symptoms; 7.2%, other symptoms; and 21.5% were asymptomatic. In addition, 59.4% of patients were hospitalized and 7.4% had a severe or critical course. A total of 57 patients developed multisystem inflammatory syndrome. A history of asthma, bronchopulmonary dysplasia, congenital heart disease, moderate to severe malnutrition, obesity, chronic neurological disease and/or age younger than 6 months were independent predictors of severity.Livinginavulnerableneighborhoodwas a protective factor. Conclusions. More than half of cases referred a history of contact with COVID-19 patients in the family setting. Hospitalization was not based on clinical criteria of severity. Severity was associated with the presence of certain comorbidities

Multisystem inflammatory syndrome (MIS) is a rare and severe post-infectious inflammatory disorder involving multiple systems (cardiovascular, gastrointestinal, dermatologic, nervous system, and haematological) without significant respiratory involvement. It is predominantly seen in children but sometimes in adults, usually after 3-6 weeks of COVID-19 infection or vaccination. It is postulated to be due to immune dysregulation. This case report adds to the limited literature available on post COVIDMISin adults, emphasizing how to reach the diagnosis after ruling out other differentials. Timely initiation of treatment gives gratifying results in most patients.
ABSTRACT
Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection may lead to multisystem inflammatory syndrome in children(MIS-C). MIS-C mostly occurs in older children and adolescents who have laboratory or epidemiological evidence of SARS-CoV-2 infection.The clinical manifestations include persistent fever, hypotension, elevated inflammation markers, and symptoms of multiple organ involvement, which is similar to Kawasaki disease.Once the disease occurs, it can progress rapidly and worsen in a short time, and most children require intensive care admission.Although the overall prognosis is good, some patients have adverse results such as death.We should strengthen the monitoring and management of suspected children and improve the level of diagnosis and treatment of the disease.
ABSTRACT
INTRODUÇÃO: A potencial associação da COVID-19 com fenômenos inflamatórios e autoimunes abre um novo capítulo na prática clínica. Entre várias condições inflamatórias descritas no pós-COVID-19, destacam-se a doença de Kawasaki e uma nova afecção denominada síndrome inflamatória multissistêmica. OBJETIVOS: Revisar, de forma prática e concisa, conceito e critérios diagnósticos da síndrome inflamatória multisistêmica, as sobreposições com a doença de Kawasaki, assim como a imunopatogênese e o tratamento desta nova e intrigante enfermidade. MÉTODOS: Revisão da literatura disponível na base de dados Pubmed, com ênfase em revisões sistemáticas com metaanálises. RESULTADOS: A síndrome inflamatória multisistêmica se configura como uma condição hiperinflamatória multiorgânica pós-viral. A condição é primordialmente pediátrica, e os primeiros casos foram descritos na Inglaterra em maio de 2020. Os critérios diagnósticos são ainda imprecisos, e incluem algumas manifestações doença de Kawasaki-símiles. A síndrome inflamatória multisistêmica difere da doença de Kawasaki, entretanto, por geralmente acometer crianças acima cinco anos e de raças negras ou hispânicas; em termos clínicos, se distingue pela alta frequência de gastroenteropatia, miocardiopatia e choque. O diagnóstico diferencial inclui sepse bacteriana, síndrome de ativação macrofágica e formas sistêmicas de artrite reumatoide. Uma hiperexpressão de interferons e de outras citocinas inflamatórias caracteriza patogenicamente a síndrome inflamatória mulsistêmica. A enfermidade é, via de regra, responsiva a cuidados de terapia intensiva, corticóides, imunoglobulina intravenosa e imunobiológicos. CONCLUSÕES: A síndrome inflamatória multisistêmica é uma nova e complexa afecção hiperinflamatória associada à exposição prévia ao SARS-CoV-2. Apresenta instigantes interfaces com a doença de Kawasaki. Apesar da descrição recente, a literatura já é quantitativamente robusta, e algumas pendências de imunopatogênese, critérios diagnósticos e terapêutica deverão ser esclarecidas em breve.
INTRODUCTION: A potential association of COVID-19 with inflammatory and autoimmune phenomena opens a new chapter in clinical practice. Among several inflammatory conditions described in the post-COVID-19 context, Kawasaki disease and a new condition named multisystem inflammatory syndrome stand out. AIMS: To review, in a practical and concise way, the concept and diagnostic criteria of multisystem inflammatory syndrome, the overlaps with Kawasaki disease, as well as the immunopathogenesis and treatment of this new and intriguing condition. METHODS: Literature review available in the Pubmed database, with emphasis on systematic reviews with meta-analyses. RESULTS: The multisystem inflammatory syndrome is a post-viral, multiorgan hyperinflammatory disorder. The condition is primarily pediatric, and the first cases were reported in England in May 2020. Diagnostic criteria are still imprecise, and include some Kawasaki disease-like manifestations. However, multisystem inflammatory syndrome differs from Kawasaki disease by usually affecting children above five years of age and of black or hispanic races; in clinical terms, it is distinguished by the high frequency of gastroenteropathy, cardiomyopathy and shock. Differential diagnosis includes bacterial sepsis, macrophage activation syndrome, and systemic forms of rheumatoid arthritis. An overexpression of interferons and other inflammatory cytokines pathogenically characterize the multisystem inflammatory syndrome. The disease is, as a rule, responsive to intensive care, steroids, intravenous immunoglobulin, and immunobiologics. CONCLUSIONS: Multisystem inflammatory syndrome is a new and complex hyperinflammatory condition associated with previous exposure to SARS-CoV-2. It shows interesting interfaces with Kawasaki disease. Despite the recent description, the literature is already quantitatively robust, and some pending issues in immunopathogenesis, diagnostic criteria and therapy should be shortly clarified.

La COVID 19 es una enfermedad que, habitualmente, no resulta grave en la edad pediátrica, excepto en niños con comorbilidades significativas subyacentes. Es muy importante reconocer los cuadros post COVID, como el síndrome inflamatorio multisistémico (SIM-C) y la COVID-19 prolongada o long COVID que pueden afectar de manera significativa a la población de niños y adolescentes. La pandemia COVID-19 también ha tenido un fuerte impacto en los aspectos sociales, emocionales y nutricionales. El aislamiento prolongado impactó en los controles de salud de niños y adolescentes con enfermedades crónicas y las coberturas de las vacunas de calendario disminuyeron significativamente. Es claro que la vacunación contra el SARSCov-2 en niños, niñas y adolescentes no sólo busca cuidar de su salud; también busca preservar la vida social y presencialidad escolar, reducir el riesgo de los cuadros post COVID-19 y mejorar la inmunidad de rebaño de la población general.
COVID-19 is a disease that is not usually serious in children, except in children with significant underlying comorbidities. Is very important to recognize post-COVID conditions such as multisystem inflammatory syndrome (SIM-C) and prolonged COVID 19 or long COVID, which can significantly affect the population of children and adolescents. The COVID -19 pandemic has also had a strong impact on social, emotional, and nutritional aspects. Prolonged isolation had an impact on health checkups for children and adolescents with chronic diseases, and coverage of scheduled vaccinations decreased significantly. It is clear that vaccination against SARSCov-2 in children and adolescents not only seeks to take care of their health , it also seeks to preserve social life and school presence, reduce the risk of post-COVID-19 conditions and improve herd immunity in the general population.

Introducción: En mayo de 2020 en Reino Unido y EE UU se documentaron casos de una enfermedad que compartía características clínicas y analíticas con la enfermedad de Kawasaki, la cual se asoció a una disregulación inmunitaria secundaria a una infección reciente por SARS-CoV-2. Objetivo: Comunicar las experiencias de la evolución y el tratamiento de una paciente con diagnóstico de esta nueva enfermedad. Presentación del caso: Adolescente de 17 años con antecedentes de haber padecido de COVID-19 seis semanas antes de su presentación en el hospital. Se recibe con lesiones mucocutáneas, polipnea, taquicardia, ictericia y astenia. Dos horas después de llegar a la unidad de cuidados intensivos comenzó con taquicardia ventricular sin pulsos, de la cual hizo dos eventos que requirieron reanimación cardiopulmonar avanzada. Fue necesario apoyo inotrópico por varios días debido a la afectación miocárdica. Después de 72 h con una fracción de eyección del ventrículo izquierdo por debajo de 35 %, comenzó a mejorar hasta la recuperación completa. Recibió tratamiento con metilprednisolona IV y con el péptido inmunoregulador cubano jusvinza. Conclusiones: El síndrome inflamatorio multisistémico asociado a COVID-19, presentado por primera vez en la provincia de Cienfuegos, es una afección nueva, que usualmente es grave y requiere cuidados intensivos debido a que produce disfunción orgánica, pero sobre todo afectación cardíaca. Tiene una presentación clínica similar a enfermedades más comunes, por lo que es fundamental estar alerta para un diagnóstico oportuno que garantice el éxito del tratamiento y evite la muerte.
Introduction: In May 2020, cases of a disease that shared clinical and analytical features with Kawasaki disease were documented in the United Kingdom and the United States, which were associated with immune dysregulation secondary to a recent SARS-CoV-2 infection. Objective: To communicate the experiences of the evolution and treatment of a patient diagnosed with this new disease. Case presentation: A 17-year-old teenager with a history of COVID-19 six weeks ago. He was admitted with mucocutaneous lesions, polypnea, tachycardia, jaundice and asthenia. Two hours after arriving at the intensive care unit, he presented pulseless ventricular tachycardia, of which he did two events that required advanced cardiopulmonary resuscitation. Inotropic support was required for several days due to myocardial involvement. After 72 hours with a left ventricular ejection fraction below 35%, he began to improve until complete recovery. He received treatment with IV methylprednisolone and the Cuban immunoregulatory peptide jusvinza. Conclusions: The multisystem inflammatory syndrome associated with COVID-19, presented for the first time in the province of Cienfuegos, is a new condition, which is usually serious and requires intensive care because it produces organic dysfunction, but above all cardiac involvement. It has a clinical presentation similar to more common diseases, so it is essential to be alert for a timely diagnosis that guarantees the success of treatment and prevents death.
ABSTRACT
Introducción: La enfermedad de Kawasaki es la principal causa de enfermedad cardiaca adquirida en la infancia, sin embargo, su diagnóstico se dificulta después de la aparición del SARS-CoV-2. Objetivo: Examinar un caso con enfermedad de Kawasaki incompleta en el contexto de la pandemia por COVID-19 y el reto diagnóstico que representa. Presentación del caso: Paciente de 5 meses de edad quien es traída por sus padres al servicio de urgencias por síntomas respiratorios superiores y múltiples episodios eméticos. Durante su hospitalización presenta fiebre de difícil control, edema en extremidades, exantema polimorfo y lengua aframbuesada, por lo que, tras descartar el síndrome inflamatorio multisistémico pediátrico temporalmente asociado al COVID 19, se diagnostica la enfermedad de Kawasaki. Se indica tratamiento con inmunoglobulina endovenosa y ácido acetilsalicílico. La paciente evolucionó de forma satisfactoria y egresó al día 10 de hospitalización. Conclusiones: La diferenciación de la enfermedad de Kawasaki con el síndrome inflamatorio multisistémico pediátrico es vital, dado que este último presenta mayor riesgo de morbilidad y mortalidad a corto plazo.
Introduction: Kawasaki disease is the main cause of heart disease acquired in childhood, however, its diagnosis is difficult after the onset of SARS-CoV-2. Objective: To examine a case with incomplete Kawasaki disease in the context of the COVID-19 pandemic and the diagnostic challenge it represents. Case presentation: A 5-month-old female patient brought by her parents to the emergency service due to upper respiratory symptoms and multiple emetic episodes. During her hospitalization, she presented fever that was difficult to control, edema in the extremities, polymorphous exanthema and a strawberry tongue, so after ruling out the pediatric multisystem inflammatory syndrome temporarily associated with COVID 19, Kawasaki disease was diagnosed. Treatment with intravenous immunoglobulin and acetylsalicylic acid is indicated. The patient progressed satisfactorily and was discharged on day 10 of hospitalization. Conclusions: The differentiation of Kawasaki disease with pediatric multisystem inflammatory syndrome is vital, given that the latter presents a higher risk of morbidity and mortality in the short term.
ABSTRACT
Multisystem inflammatory syndrome in children (MIS-C) is a type of hyperinflammatory symptoms similar to Kawasaki disease after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and is commonly observed in children aged 8-10 years. Primary therapeutic medications for MIS-C are intravenous immunoglobulins and glucocorticoids. It has been reported that biologics, such as IL-1 receptor antagonist anakinra, IL-6 receptor antagonist tocilizumab, and TNF-α receptor antagonist infliximab, can be used as an option for critically ill patients. This article elaborates on the mechanism of action of the above biologics and discusses the efficacy and safety biologics in the treatment of MIS-C after SARS-CoV-2 infection, in order to provide methods for the treatment of MIS-C with severe symptoms.

La infección por COVID-19 en la población pediátrica tiene un curso leve en la mayoría de los casos. Sin embargo, en abril de 2020 se reportan por primera vez casos de niños que presentan un cuadro clínico compatible con un síndrome inflamatorio multisistémico de expresividad clínica variable y que se vincula a una infección reciente o activa por SARS-CoV-2. En este reporte se presenta un caso de síndrome inflamatorio multisistémico pediátrico vinculado a SARS-CoV-2 (SIM-PedS) cuyo diagnóstico fue dificultoso dada la variabilidad clínica del mismo. Se muestra el diagnóstico diferencial llevado a cabo y se pone de manifiesto la necesidad de tener en cuenta todos los signos y síntomas para poder llevar a cabo el diagnóstico de forma precoz, un manejo óptimo y disminuir la morbimortalidad secundaria. Este síndrome comparte rasgos clínicos y analíticos similares a la enfermedad de Kawasaki y al síndrome de shock tóxico o de activación macrofágica. Esto dificulta llegar al diagnóstico de forma precoz, precisando una valoración multidisciplinar por parte de diferentes especialistas pediátricos, así como seguir unas recomendaciones y protocolos para el diagnóstico, estabilización y tratamiento con el objetivo de homogeneizar el manejo en los diferentes centros de urgencia y hospitalización
In children, COVID-19 infection has usually a mild course. However, cases of children with multisystemic inflammatory syndrome presenting a variable clinical expression linked to a recent or active infection by SARS-CoV-2 were reported in April 2020. This report presents a case of paediatric inflammatory multisystemic syndrome temporally associated with SARS-CoV-2 infection (PIMS-TS), whose diagnosis was difficult given the variability in clinical expression. The differential diagnosis is shown and highlights the need to take into account all the signs and symptoms to get an early diagnosis, optimal management and reduce secondary morbidity and mortality. This variability in clinical manifestations with clinical and analytical features similar to Kawasaki syndrome, toxic shock syndrome or macrophage activation makes it difficult to reach an early diagnosis. It shows the need for a multidisciplinary assessment of different paediatric specialists, as well as to follow recommendations and protocols for the diagnosis, stabilization and treatment in order to homogenize the management in the emergency and hospitalization departments.
