ABSTRACT
BACKGROUND: Coronavirus disease 2019 (COVID-19) is usually mild and self-limited in children. However, a few Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infections in children may progress to severe disease with respiratory distress or can result in a multisystem inflammatory syndrome (MIS-C) associated with COVID-19. The immune mechanisms for these differential clinical outcomes are largely unknown. METHODS: A prospective cohort study was performed to analyze the laboratory parameters, antibody response, immune phenotypes and cytokine profiles of 51 children with different clinical presentations of COVID-19. RESULTS: We found that the absolute lymphocyte counts gradually decreased with disease severity. Furthermore, SARS-CoV-2 IgG levels in the acute phase and convalescence were not significantly different in patients with different disease severity. A decrease in CD3 + , CD4 + and CD8 + T cells was observed as disease severity increased. Both CD4 + and CD8 + T cells were activated in children with COVID-19, but no difference in the percentage of HLADR + -expressing cells was detected across the severity groups. In contrast, MIS-C patients exhibited augmented exhausted effector memory CD8 + T cells. Interestingly, the cytokine profile in sera of moderate/severe and MIS-C patients revealed an increase in anti-inflammatory IL-1RA and a suppression of tumor necrosis factor-α, RANTES, eotaxin and PDGF-BB. MIS-C patients also exhibited augmented IL-1ß. CONCLUSIONS: We report distinct immune profiles dependent on severity in pediatric COVID-19 patients. Further investigation in a larger population will help unravel the immune mechanisms underlying pediatric COVID-19.

El incremento de la expectativa de vida con el advenimiento de la terapia antirretroviral de alta eficacia plantea desafíos en cuanto a la toxicidad e interacciones medicamentosas. El síndrome de Cushing exógeno por interacción entre ritonavir y fluticasona inhalada en niños con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica es infrecuente. Hasta el momento, hay 20 casos reportados. Se describen 3 casos pediátricos con diagnóstico de infección por virus de la inmunodeficiencia humana y patología pulmonar crónica que presentaron síndrome de Cushing exógeno con fluticasona inhalada en dosis habituales por la interacción medicamentosa entre esta y ritonavir. Los pacientes resolvieron el cuadro clínico luego de 2-4 meses de suspensión de la fluticasona y permanecieron asintomáticos en el seguimiento
The increase in life expectancy with the advent of highly effective antiretroviral therapy poses challenges in terms of toxicity and drug interactions. Exogenous Cushing syndrome by interaction between ritonavir and inhaled fluticasone in children diagnosed with human immunodeficiency virus infection and chronic pulmonary pathology is rare. So far, there are 20 cases reported. Three pediatric cases are reported, with a diagnosis of human immunodeficiency virus infection and chronic pulmonary pathology who presented exogenous Cushing syndrome with inhaled fluticasone at usual doses due to drug interaction between it and ritonavir. The patients resolved the clinical Síndrome de Cushing exógeno por interacción medicamentosa de ritonavir y fluticasona inhalada. Reporte de tres casos pediátricos Exogenous Cushing syndrome due to drug interaction of ritonavir and inhaled fluticasone. Report of three pediatric cases picture after 2-4 months of fluticasone suspension and remain asymptomatic in the follow-up.

Plasmablastic lymphoma is a rare and aggressive subtype of diffuse large B cell non-Hodgkin lymphoma, originally described in the oral cavity of male adults with acquired immune deficiency syndrome. It is composed of neoplastic ceils which resemble immunoblasts but present immunophenotype distinctive of plasma cell and Epstein-Barr virus latent infection. In children, it is an even rarer disease. We present a case of oral plasmablastic lymphoma in a vertically transmitted human immunodeficiency virus-positive five-year-old child.
El linfoma plasmablástico es un subtipo raro y agresivo de linfoma no Hodgkin de células grandes B, descrito inicialmente en la cavidad oral de adultos varones con enfermedad por virus de inmunodeficiencia humana/síndrome de inmunodeficiencia adquirida. Se compone de una proliferación de células neoplásicas que se asemejan a los inmunoblastos, pero presentan inmunofenotipo característico de célula plasmática e infección latente por el virus de Epstein-Barr. En la población pediátrica, es una entidad excepcional. Presentamos el caso de una niña de 5 años de edad, con enfermedad por virus de inmunodeficiencia humana / síndrome de inmunodeficiencia adquirida de transmisión vertical con linfoma plasmablástico de cavidad oral.
