ABSTRACT

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


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

ABSTRACT

Introducción. Las infecciones invasivas por Streptococcus pyogenes (IISP) presentan elevada morbimortalidad aún en la actualidad; no obstante, a nivel regional, existen escasas publicaciones en pediatría. Objetivo. Describir la prevalencia, los factores predisponentes y las características clínicas de niños internados por IISP, analizar los factores de riesgo asociados a bacteriemia y letalidad. Material y métodos. Estudio retrospectivo, descriptivo de IISP en niños ≤ 18 años, internados en Pediatría de 20 centros asistenciales del país, entre 2010 y 2012. Variables evaluadas: edad, sexo, focos clínicos iniciales y tardíos, patología crónica previa, factores predisponentes, tratamiento y evolución. Resultados. Se analizaron 143 pacientes. Incidencia de 4,97 casos/10 000 egresos. Mediana de edad 54 meses; tenían patología crónica previa 11,2%. Tuvieron factores predisponentes 67,1%. Las formas de presentación más frecuentes fueron la piel y las partes blandas en 77, sepsis en 30, osteoarticulares en 19, fascitis necrotizante en 13, síndrome de shock tóxico en 11. Se aisló Streptococcus pyogenes en 56,6% de los hemocultivos; la presencia de más de un foco clínico y la ausencia de cirugía se asociaron a bacteriemia (OR 4,8; p= 0,003 y OR 3,1; p= 0,0012, respectivamente). El promedio de internación fue 13,4 días. La tasa de letalidad fue 7,6% asociada a síndrome de shock tóxico (OR 10; p= 0,005), fascitis necrotizante (OR 104; p < 0,0001) e ingreso a la Unidad de Cuidados Intensivos Pediátricos (OR 26; p < 0,001). Conclusiones. La mayoría de las IISP se presentaron en pacientes sin patología crónica previa. Los focos de presentación, frecuentemente con bacteriemia, fueron la piel y las partes blandas. Hubo asociación estadísticamente significativa entre bacteriemia y ≥ 2 focos iniciales y ausencia de cirugía. La letalidad, asociada a SSTS y fascitis necrotizante, fue similar a otras publicaciones.


Introduction. Invasive Streptococcus pyogenes infections (ISpIs) cause a high morbidity and mortality, even at present; however, at a regional level there are few publications on this subject in the field of pediatrics. Objective. To describe the prevalence, predisposing factors and clinical characteristics of children hospitalized for ISpI, and analyze risk factors associated with bacteremia and lethality. Material and methods. Retrospective, descriptive study on ISpIs in children <18 years old hospitalized in the Pediatric Ward of 20 healthcare facilities across Argentina between 2010 and 2012. Assessed outcome measures: age, gender, early and late clinical sources of infection, prior chronic condition, predisposing factors, treatment and evolution. Results. One hundred and forty-three patients were analyzed. The incidence of ISpI was 4.97 cases/10 000 hospital discharges. Patients' median age was 54 months old, and 11.2% had a prior chronic condition. Also, 67.1% had predisposing factors. The most common clinical manifestations were in the skin and soft tissue in 77 patients, sepsis in 30, bone and joint involvement in 19, necrotizing fasciitis in 13, and toxic shock syndrome in 11. Streptococcus pyogenes was isolated in the blood cultures of 56.6%. More than one clinical source of infection and no surgery were associated with bacteremia (odds ratio [OR]: 4.8, p= 0.003 and OR: 3.1, p= 0.0012, respectively). The average length of stay in the hospital was 13.4 days. Fatality rate was 7.6% in association with toxic shock syndrome (OR: 10, p= 0.005), necrotizing fasciitis (OR: 104, p < 0.0001) and admission to the Pediatric Intensive Care Unit (OR: 26, p < 0.001). Conclusions. Most ISpIs were observed in patients without a prior chronic condition. The most common manifestation was, frequently with bacteremia, in the skin and soft tissue. A statistically significant association was observed between bacteremia and ≥2 early sources of infection and no surgery. Fatality rate, in association with streptococcal toxic shock syndrome and necrotizing fasciitis, was similar to that observed in other publications.
