ABSTRACT
BACKGROUND: Understanding the epidemiology and clinical course of multisystem inflammatory syndrome in children (MIS-C) and its temporal association with coronavirus disease 2019 (Covid-19) is important, given the clinical and public health implications of the syndrome. METHODS: We conducted targeted surveillance for MIS-C from March 15 to May 20, 2020, in pediatric health centers across the United States. The case definition included six criteria: serious illness leading to hospitalization, an age of less than 21 years, fever that lasted for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on reverse-transcriptase polymerase chain reaction (RT-PCR), antibody testing, or exposure to persons with Covid-19 in the past month. Clinicians abstracted the data onto standardized forms. RESULTS: We report on 186 patients with MIS-C in 26 states. The median age was 8.3 years, 115 patients (62%) were male, 135 (73%) had previously been healthy, 131 (70%) were positive for SARS-CoV-2 by RT-PCR or antibody testing, and 164 (88%) were hospitalized after April 16, 2020. Organ-system involvement included the gastrointestinal system in 171 patients (92%), cardiovascular in 149 (80%), hematologic in 142 (76%), mucocutaneous in 137 (74%), and respiratory in 131 (70%). The median duration of hospitalization was 7 days (interquartile range, 4 to 10); 148 patients (80%) received intensive care, 37 (20%) received mechanical ventilation, 90 (48%) received vasoactive support, and 4 (2%) died. Coronary-artery aneurysms (z scores ≥2.5) were documented in 15 patients (8%), and Kawasaki's disease-like features were documented in 74 (40%). Most patients (171 [92%]) had elevations in at least four biomarkers indicating inflammation. The use of immunomodulating therapies was common: intravenous immune globulin was used in 144 (77%), glucocorticoids in 91 (49%), and interleukin-6 or 1RA inhibitors in 38 (20%). CONCLUSIONS: Multisystem inflammatory syndrome in children associated with SARS-CoV-2 led to serious and life-threatening illness in previously healthy children and adolescents.

OBJECTIVES: Extracorporeal membrane oxygenation (ECMO) has been used successfully to support adults with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related cardiac or respiratory failure refractory to conventional therapies. Comprehensive reports of children and adolescents with SARS-CoV-2-related ECMO support for conditions, including multisystem inflammatory syndrome in children (MIS-C) and acute COVID-19, are needed. DESIGN: Case series of patients from the Overcoming COVID-19 public health surveillance registry. SETTING: Sixty-three hospitals in 32 U.S. states reporting to the registry between March 15, 2020, and December 31, 2021. PATIENTS: Patients less than 21 years admitted to the ICU meeting Centers for Disease Control criteria for MIS-C or acute COVID-19. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The final cohort included 2,733 patients with MIS-C ( n = 1,530; 37 [2.4%] requiring ECMO) or acute COVID-19 ( n = 1,203; 71 [5.9%] requiring ECMO). ECMO patients in both groups were older than those without ECMO support (MIS-C median 15.4 vs 9.9 yr; acute COVID-19 median 15.3 vs 13.6 yr). The body mass index percentile was similar in the MIS-C ECMO versus no ECMO groups (89.9 vs 85.8; p = 0.22) but higher in the COVID-19 ECMO versus no ECMO groups (98.3 vs 96.5; p = 0.03). Patients on ECMO with MIS-C versus COVID-19 were supported more often with venoarterial ECMO (92% vs 41%) for primary cardiac indications (87% vs 23%), had ECMO initiated earlier (median 1 vs 5 d from hospitalization), shorter ECMO courses (median 3.9 vs 14 d), shorter hospital length of stay (median 20 vs 52 d), lower in-hospital mortality (27% vs 37%), and less major morbidity at discharge in survivors (new tracheostomy, oxygen or mechanical ventilation need or neurologic deficit; 0% vs 11%, 0% vs 20%, and 8% vs 15%, respectively). Most patients with MIS-C requiring ECMO support (87%) were admitted during the pre-Delta (variant B.1.617.2) period, while most patients with acute COVID-19 requiring ECMO support (70%) were admitted during the Delta variant period. CONCLUSIONS: ECMO support for SARS-CoV-2-related critical illness was uncommon, but type, initiation, and duration of ECMO use in MIS-C and acute COVID-19 were markedly different. Like pre-pandemic pediatric ECMO cohorts, most patients survived to hospital discharge.

INTRODUCTION: Pediatric critical care patients with COVID-19 treated in Peru have higher mortality than those previously reported from other countries. Pediatric providers have reported a high number of patients without comorbidities presenting with hemorrhagic strokes associated with COVID-19. We present a study analyzing the factors associated with mortality in this setting. METHODS: Prospective case-control study that included patients <17 years old admitted to a pediatric critical care unit with a positive test confirming COVID-19. The primary outcome was mortality. Fisher's exact test and the Mann-Whitney U test were used for the analysis. RESULTS: Forty-seven patients were admitted to critical care. The mortality of our study is 21.3%. The mortality of patients with neurological presentation was 45.5%, which was significantly higher than the mortality of acute COVID-19 (26.7%) and MIS-C (4.8%), p 0.18. Other risk factors for mortality in our cohort were strokes and comorbidities. Only one patient presenting with hemorrhagic stroke had an undiagnosed comorbidity. CONCLUSION: Cerebrovascular events associated with COVID-19 in pediatric patients, including infants, must be recognized as one of the more severe presentations of this infection in pediatric patients. IMPACT: Pediatric patients with COVID-19 can present with hemorrhagic and ischemic strokes on presentation. Neurological presentation in pediatric patients with COVID-19 has high mortality. Mortality of pediatric patients with COVID-19 is associated with comorbidities. Pediatric presentation and outcomes of COVID-19 in different regions can be novel to previously described.

OBJECTIVES: To identify associations between augmented renal clearance (ARC) in pediatric patients treated for suspected sepsis and vancomycin pharmacokinetics. ARC has been associated with lower serum drug levels in both adult and pediatric cohorts for multiple drugs. We hypothesize that presence of ARC is associated with subtherapeutic initial vancomycin trough level (VTL). DESIGN: Retrospective study, with patients divided into two groups based on the presence of ARC (estimated glomerular filtration rate [eGFR] above 130 mL/min/1.73 m2) in comparison with VTL. Multivariable logistic regression analysis was performed to evaluate the association between eGFR and subtherapeutic VTL. SETTING: Tertiary children's hospital. PATIENTS: Hospitalized children (0-18 yr) initiated on empiric vancomycin therapy for suspected sepsis. INTERVENTIONS: Retrospective measurement of VTL, eGFR, and clinical variables. MEASUREMENTS AND MAIN RESULTS: Seventy-three patients were treated with empiric vancomycin for sepsis. ARC was present in 32 patients (44%). Subtherapeutic first VTL was present in 40 patients (55%). Higher eGFR was independently associated with subtherapeutic VTL in the multivariable logistic regression analysis. CONCLUSIONS: Subtherapeutic VTL is associated with ARC in our single-center retrospective cohort of children with suspected sepsis. This problem may present a potential risk of treatment failure in Gram-positive sepsis or longer time to clinical response. Prospective studies to investigate the clinical significance and effect of optimizing vancomycin dose in patients with ARC are recommended.

OPINION STATEMENT: Rhabdomyosarcoma (RMS) is well known as a pediatric disease. Most of the knowledge, like biology, genetics, and treatments of this disease, comes from studies done in that age group. The two subtypes of RMS, embryonic RMS and alveolar RMS, that affect mainly the pediatric population are well described in the literature and that has had an impact on the improvement in overall survival during the past 20 years. RMS in the adult population has a low incidence, therefor the study of RMS in this group is challenging. Pleomorphic RMS is the subtype that mainly affects adults and its biology and genetics are not yet completely understood and described. The risk factors for this tumor and the differences among adults and children is also poorly understood. The treatments for adults that have RMS are not standardized having an impact on the overall survival. Pleomorphic RMS has, compared to other adult sarcomas, poor overall survival. Adult patients with RMS have poor prognosis. The standardization of treatments for the adult population is necessary as maybe new treatments for this specific group. There are new treatment options that are being studied mostly in pediatrics and young adults. Immunotherapy is currently proposed as an important treatment possibility including different techniques like vaccination, antigen-mediated therapy, and immune checkpoints. Even if we have a better understanding of RMS, there are still unanswered questions. The improvements seen in the pediatric population are encouraging, but there is still the need to enhance better therapies for adults with RMS.

To characterize kidney replacement therapy (KRT) and pediatric extracorporeal membrane oxygenation (ECMO) outcomes and to identify the optimal timing of KRT initiation during ECMO associated with increased survival. Observational retrospective cohort study using the Extracorporeal Life Support Organization Registry database in children (0-18 yo) on ECMO from January 1, 2016, to December 31, 2020. Of the 14,318 ECMO runs analyzed, 26% of patients received KRT during ECMO. Patients requiring KRT before ECMO had increased mortality to ECMO decannulation (29% vs. 17%, OR 1.97, P < 0.001) and to hospital discharge (58% vs. 39%, OR 2.16, P < 0.001). Patients requiring KRT during ECMO had an increased mortality to ECMO decannulation (25% vs. 15%, OR 1.85, P < 0.001) and to hospital discharge (56% vs. 34%, OR 2.47, P < 0.001). Multivariable logistic regression demonstrated that the need for KRT during ECMO was an independent predictor for mortality to ECMO decannulation (OR 1.49, P < 0.001) and to hospital discharge (OR 2.02, P < 0.001). Patients initiated on KRT between 24 and 72 hours after cannulation were more likely to survive to ECMO decannulation and showed a trend towards survival to hospital discharge as compared to those initiated before 24 hours and after 72 hours.

Oxygen therapy is essential for the survival of preterm babies and critically ill newborns; however, it has the potential to cause harm through hypoxemia or hyperoxemia. Newborns with complex congenital heart diseases (CHD) suffer from oxygen fluctuations due to the disease and its treatments, altering pre and postnatal development. The objective of this study is to evaluate the evidence for using a hypoxic mixture to decrease pulmonary over-circulation and improve systemic perfusion before surgical interventions in newborns with complex CHD that course with pulmonary over-circulation and systemic hypoperfusion. A search was conducted in PubMed, EMBASE, LILACS, Scielo, Taylor and Francis, SAGE, and Science Direct databases from 2000 to 2022 by two independent authors, including articles with hypoxic mixture treatment in observational studies or trials, with pre-treatment and post-treatment measurements in the same patient, or two groups or more comparisons. Six articles were selected, with a total of 75 patients. The primary outcome was improved systemic circulation and decreased pulmonary over-circulation measured directly with Qp/Qs and indirectly with oxygen saturation and cerebral near-infrared spectroscopy (NIRS). In addition, we performed a meta-analysis for oxygen saturation and cerebral NIRS. Oxygen saturation was the value uniformly reported; three studies reported a significantly lower oxygen saturation after the hypoxic mixture. The cerebral NIRS was measured in 4 studies, with inconsistent results. After using the hypoxic mixture, the Qp/Qs calculation was lower in the two studies but was not statistically significant. The meta-analysis for oxygen saturation showed a fixed effect post-hypoxic therapy of -0.7 (-1.06; -0.35), p < 0.001. The meta-analysis of two studies that measured cerebral NIRS did not show a statistically significant difference at 12 and 24 hours. In conclusion, this is the first systematic review and meta-analysis regarding the pre-operative use of hypoxic gas mixtures for newborns with complex congenital heart disease. Treatment results in lower oxygen saturations, but there is a lack of evidence of improvement in systemic perfusion. The utilization of this therapy is controversial, and better evidence is necessary.
ABSTRACT
In 2019, 80% of the 7.4 million global child deaths occurred in low- and middle-income countries (LMICs). Global and regional estimates of cause of hospital death and admission in LMIC children are needed to guide global and local priority setting and resource allocation but are currently lacking. The study objective was to estimate global and regional prevalence for common causes of pediatric hospital mortality and admission in LMICs. We performed a systematic review and meta-analysis to identify LMIC observational studies published January 1, 2005-February 26, 2021. Eligible studies included: a general pediatric admission population, a cause of admission or death, and total admissions. We excluded studies with data before 2,000 or without a full text. Two authors independently screened and extracted data. We performed methodological assessment using domains adapted from the Quality in Prognosis Studies tool. Data were pooled using random-effects models where possible. We reported prevalence as a proportion of cause of death or admission per 1,000 admissions with 95% confidence intervals (95% CI). Our search identified 29,637 texts. After duplicate removal and screening, we analyzed 253 studies representing 21.8 million pediatric hospitalizations in 59 LMICs. All-cause pediatric hospital mortality was 4.1% [95% CI 3.4%-4.7%]. The most common causes of mortality (deaths/1,000 admissions) were infectious [12 (95% CI 9-14)]; respiratory [9 (95% CI 5-13)]; and gastrointestinal [9 (95% CI 6-11)]. Common causes of admission (cases/1,000 admissions) were respiratory [255 (95% CI 231-280)]; infectious [214 (95% CI 193-234)]; and gastrointestinal [166 (95% CI 143-190)]. We observed regional variation in estimates. Pediatric hospital mortality remains high in LMICs. Global child health efforts must include measures to reduce hospital mortality including basic emergency and critical care services tailored to the local disease burden. Resources are urgently needed to promote equity in child health research, support researchers, and collect high-quality data in LMICs to further guide priority setting and resource allocation.
ABSTRACT
OBJECTIVE: To describe lung mechanics in Pediatric Acute Respiratory Distress Syndrome (PARDS) associated with acute COVID-19 and MIS-C with respiratory failure. METHODS: A concurrent multicenter observational study was performed, analyzing clinical variables and pulmonary mechanics of PARDS associated with COVID-19 in 4 Pediatric intensive care units (PICU) in Peru. The subgroup analysis included PARDS associated with multisystem inflammatory syndrome in children (MIS-C), MIS-PARDS, and PARDS with COVID-19 primary respiratory infection, C-PARDS. In addition, receiver operating characteristic (ROC) curve analysis for mortality and lung mechanics was performed. RESULTS: 30 patients were included. The age was 7.5 (4-11) years, 60% were male, and mortality was 23%. 47% corresponded to MIS-PARDS and 53% to C-PARDS groups. C-PARDS had positive RT-PCR in 67% and MIS-PARDS none (p < 0.001). C-PARDS group had more profound hypoxemia (P/F ratio < 100, 86% vs. 38%, p < 0.01) and higher driving-pressure [14(10-22) vs 10(10-12) cmH2O], and lower compliance of the respiratory system (CRS) [0.5 (0.3-0.6) vs 0.7(0.6-0.8) ml/ kg/cmH2O] compared with MIS-PARDS (all p < 0.05). The ROC analysis for mortality showed that driving pressure had the best performance [AUC 0.91(95%CI0.81-1.00), with the best cut-off point of 15 cmH2O (100% sensitivity and 87% specificity). Mortality in C-PARDS was 38% and 7% in MIS-PARDS (p = 0.09). MV-free days were 12(0-23) in C-PARDS and 23(21-25) in MIS-PARDS (p = 0.02). CONCLUSION: Patients with C-PARDS have lung mechanics characteristics similar to classic moderate to severe PARDS. This was not observed in patients with MIS-C. As seen in other studies, a driving pressure ≥ 15 cmH2O was the best discriminator for mortality. These findings may help guide ventilatory management strategies for these two different presentations.

Current therapies frequently used for refractory septic shock include hydrocortisone, vasopressin, extracorporeal membrane oxygenation (ECMO) support, inodilators, levosimendan and methylene blue. The evidence for these treatments is very limited. We present a case of a 5-year-old patient with refractory septic shock, secondary to Listeria monocytogenes meningitis. She presented with status epilepticus and developed septic shock. Shock persisted despite multiple high-dose vasoactive medications. ECMO support was not available. The medical team decided to use methylene blue to revert the vasoplegia, with excellent results. Shortly after the administration, vasopressors were weaned off and the high lactate cleared. She developed severe neurological sequelae due to brain haemorrhage secondary to the Listeria meningitis. The evidence supporting methylene blue for refractory septic shock in paediatric patients is limited. This case represents the effectiveness of this therapy without secondary effects.

New diagnoses of leukaemia and other malignancies are recently being made in paediatric patients with COVID-19. The rates of mortality and morbidity in some of these children are expected to be higher. In new cases, concurrent diagnosis can be difficult because multisystemic inflammatory syndrome (MIS-C) and malignancies have similar clinical presentations. We present the case of a preteenage child where the diagnosis of leukaemia was complicated and delayed by a multisystem involvement and an inconclusive bone marrow study. Clinical teams managing children with COVID-19 and MIS-C should suspect leukaemia and other malignancies when the clinical course is complicated and bone marrow suppression is persistent. Prompt diagnosis will allow start of treatment on time, minimising complications.

Background: Children with cancer are at risk of critical disease and mortality from COVID-19 infection. In this study, we describe the clinical characteristics of pediatric patients with cancer and COVID-19 from multiple Latin American centers and risk factors associated with mortality in this population. Methods: This study is a multicenter, prospective cohort study conducted at 12 hospitals from 6 Latin American countries (Argentina, Bolivia, Colombia, Ecuador, Honduras and Peru) from April to November 2021. Patients younger than 14 years of age that had an oncological diagnosis and COVID-19 or multisystemic inflammatory syndrome in children (MIS-C) who were treated in the inpatient setting were included. The primary exposure was the diagnosis and treatment status, and the primary outcome was mortality. We defined "new diagnosis" as patients with no previous diagnosis of cancer, "established diagnosis" as patients with cancer and ongoing treatment and "relapse" as patients with cancer and ongoing treatment that had a prior cancer-free period. A frequentist analysis was performed including a multivariate logistic regression for mortality. Results: Two hundred and ten patients were included in the study; 30 (14%) died during the study period and 67% of patients who died were admitted to critical care. Demographics were similar in survivors and non-survivors. Patients with low weight for age (<-2SD) had higher mortality (28 vs. 3%, p = 0.019). There was statistically significant difference of mortality between patients with new diagnosis (36.7%), established diagnosis (1.4%) and relapse (60%), (p <0.001). Most patients had hematological cancers (69%) and they had higher mortality (18%) compared to solid tumors (6%, p= 0.032). Patients with concomitant bacterial infections had higher mortality (40%, p = 0.001). MIS-C, respiratory distress, cardiovascular symptoms, altered mental status and acute kidney injury on admission were associated with higher mortality. Acidosis, hypoxemia, lymphocytosis, severe neutropenia, anemia and thrombocytopenia on admission were also associated with mortality. A multivariate logistic regression showed risk factors associated with mortality: concomitant bacterial infection OR 3 95%CI (1.1-8.5), respiratory symptoms OR 5.7 95%CI (1.7-19.4), cardiovascular OR 5.2 95%CI (1.2-14.2), new cancer diagnosis OR 12 95%CI (1.3-102) and relapse OR 25 95%CI (2.9-214). Conclusion: Our study shows that pediatric patients with new onset diagnosis of cancer and patients with relapse have higher odds of all-cause mortality in the setting of COVID-19. This information would help develop an early identification of patients with cancer and COVID-19 with higher risk of mortality.
ABSTRACT
Background: The majority of childhood deaths occur in low- and middle-income countries (LMICs). Many of these deaths are avoidable with basic critical care interventions. Quantifying the burden of pediatric critical illness in LMICs is essential for targeting interventions to reduce childhood mortality. Objective: To determine the burden of hospitalization and mortality associated with acute pediatric critical illness in LMICs through a systematic review and meta-analysis of the literature. Data Sources and Search Strategy: We will identify eligible studies by searching MEDLINE, EMBASE, CINAHL, and LILACS using MeSH terms and keywords. Results will be limited to infants or children (ages >28 days to 12 years) hospitalized in LMICs and publications in English, Spanish, or French. Publications with non-original data (e.g., comments, editorials, letters, notes, conference materials) will be excluded. Study Selection: We will include observational studies published since January 1, 2005, that meet all eligibility criteria and for which a full text can be located. Data Extraction: Data extraction will include information related to study characteristics, hospital characteristics, underlying population characteristics, patient population characteristics, and outcomes. Data Synthesis: We will extract and report data on study, hospital, and patient characteristics; outcomes; and risk of bias. We will report the causes of admission and mortality by region, country income level, and age. We will report or calculate the case fatality rate (CFR) for each diagnosis when data allow. Conclusions: By understanding the burden of pediatric critical illness in LMICs, we can advocate for resources and inform resource allocation and investment decisions to improve the management and outcomes of children with acute pediatric critical illness in LMICs.
ABSTRACT
Pediatric acute respiratory distress syndrome (PARDS) is a frequent diagnosis in critical care. This inflammatory process has different stages characterized by mild-to-severe hypoxia, and the management will vary according to the severity. New definitions for pediatric patients were published in 2015; new epidemiological evidence revising those definitions has helped understand the mortality associated with PARDS and the impact on ventilation. The strategies to protect the lungs during mechanical ventilation have been successful in reducing mortality and complications. In clinical situations where high levels of critical support are limited, other therapies with a lower level of evidence can be attempted to gain time without worsening the ongoing pulmonary injury. We offer a complete narrative revision of this syndrome, with the critical management of these patients as a priority.
El síndrome de dificultad respiratoria aguda pediátrica (SDRAP) es un diagnóstico frecuente en cuidados intensivos. Este proceso inflamatorio se caracteriza por diferentes grados de hipoxia, de leve a grave, y el manejo varía de acuerdo con la gravedad. En 2015 se publicaron nuevas definiciones para pacientes pediátricos, así como nueva evidencia epidemiológica, que toma como punto de partida dichas definiciones, lo cual ha ayudado a entender la mortalidad asociada y el impacto del manejo ventilatorio con respecto a la morbilidad en este síndrome. Las estrategias que protegen los pulmones durante la ventilación mecánica han sido exitosas en reducir la mortalidad y las complicaciones subsecuentes. En situaciones en las que existen limitaciones que impiden suministrar altos niveles de soporte crítico se pueden implementar otras medidas de menor evidencia para ganar tiempo e impedir que se extiendan las lesiones pulmonares. A continuación, se ofrece una revisión narrativa completa de este síndrome, con un enfoque que prioriza el manejo crítico de estos pacientes.

BACKGROUND: Macrophage activation syndrome (MAS) is characterized by excessive activation of macrophages and lymphocytes, leading to multiorgan dysfunction. As the initial manifestation of systemic lupus erythematosus (SLE), MAS is rare in children. Due to the COVID-19 pandemic, it is vital to identify the MAS as it shares similar characteristics with the multisystem inflammatory syndrome in children (MIS-C). CASE REPORT: We report the case of an 11-year-old male adolescent with symptoms of MIS-C. Although with negative results of RT-PCR (reverse transcription-polymerase chain reaction) and serology for SARS-CoV-2, contact with a positive COVID-19 relative was reported. When admitted to a referral hospital center, the patient received standard treatment for MIS-C. Although the same scheme was given on three occasions, the patient showed no response to initial therapy. Thus, the patient was classified as a refractory case. When the study was extended to other differential diagnoses, we found MAS associated with SLE. Therefore, the patient was treated with etoposide, cyclosporine, dexamethasone, and methotrexate and showed a good clinical response. CONCLUSIONS: MAS associated with SLE is rare in the pediatric population. MAS shares inflammatory markers with the MIS-C and is often confused with rheumatologic, infectious, and neoplastic entities. Reporting this case is important to identify differential diagnoses in patients presenting as MIS-C and decide on timely treatment, as it could be harmful or even fatal if a definitive diagnosis is not obtained on time.
INTRODUCCIÓN: El síndrome de activación de macrófagos (SAM) se caracteriza por una activación excesiva de los macrófagos y de los linfocitos que conduce a una disfunción multiorgánica. Como manifestación inicial del lupus eritematoso sistémico (LES), el SAM es poco común en la infancia. Debido a la pandemia de COVID-19, es importante identificar el SAM, ya que comparte características similares con el síndrome inflamatorio multisistémico en niños (MIS-C, por sus siglas en inglés). CASO CLÍNICO: Presentamos el caso de un varón de 11 años con síntomas de MIS-C. Resultó negativo en la prueba de reacción en cadena de la polimerasa con retrotranscriptasa y en la serología para SARS-CoV-2, aunque reportó contacto con un familiar positivo para COVID-19. Ingresó en un centro hospitalario de referencia y recibió tratamiento estandarizado para MIS-C. A pesar de recibir el mismo esquema en tres ocasiones, no mostró respuesta a la terapia inicial, por lo que fue clasificado como caso refractario. Al ampliar el estudio para otros diferenciales, se encontró SAM asociado con LES, por lo que el paciente recibió tratamiento con etopósido, ciclosporina, dexametasona y metotrexato, y mostró buena respuesta clínica. CONCLUSIONES: La asociación entre el SAM y el LES es rara en la población pediátrica. El SAM comparte marcadores inflamatorios con el MIS-C y suele confundirse con enfermedades reumatológicas, infecciosas y neoplásicas. La importancia de reportar este caso es identificar los diagnósticos diferenciales en los pacientes que se presentan como MIS-C, y decidir el tratamiento con prontitud, pues podría ser dañino o incluso fatal si no se obtiene un diagnóstico definitivo a tiempo.

OBJECTIVE: Dexmedetomidine has become a widely used drug in PICUs for sedation. We aim to determine the effects of clonidine on pediatric patients after dexmedetomidine use. METHODS: This was a retrospective cohort study that evaluated all pediatric patients admitted to a tertiary PICU who received dexmedetomidine infusion for >48 hours. Outcomes in patients exposed to clonidine (CLON) were compared with those of patients who were not exposed (NoCLON). RESULTS: A total of 216 patients were included in this study (43 CLON and 173 NoCLON). The primary outcome, agitation, was less in the CLON cohort (9.3%) than in the NoCLON cohort (9.3% versus 29.5%, respectively; p < 0.01). Hospital LOS was longer in the CLON group (59 versus 20 days, p < 0.01), as was PICU LOS (37.4 versus 11.1 days, p < 0.01). There was no significant difference in the occurrence of increased heart rate or blood pressure between the 2 cohorts. Patients exposed to concurrent midazolam and opioid infusions had higher incidence of agitation when they did not receive clonidine (CLON 8% versus NoCLON 37%, OR 0.15; 95% CI, 0.05-0.51; p < 0.01). In contrast, there was no difference in the incidence of agitation for the CLON group versus the NoCLON group when dexmedetomidine was administered alone (25% versus 19%, OR 1.4; p = 0.99). CONCLUSIONS: Our study confirms the importance and effectiveness of clonidine to treat agitation after dexmedetomidine discontinuation. A validated withdrawal scoring tool can help better define dexmedetomidine withdrawal in pediatric patients.
ABSTRACT
INTRODUCTION: The association of COVID-19 with diabetes mellitus is bidirectional. In one direction, diabetes mellitus is associated with an increased risk of severe COVID-19. In the opposite direction, in patients with COVID-19 new-onset diabetes mellitus, severe diabetic ketoacidosis and severe metabolic complications have been described. CLINICAL CASE: This report describes two patients with diabetes mellitus who came to our hospital with ketoacidosis resulting from new-onset diabetes mellitus. We describe the clinical course and the management approach during the COVID-19 pandemic. CONCLUSION: COVID-19 is associated with metabolic complications such as severe diabetic ketoacidosis.
INTRODUCCIÓN: La relación entre la enfermedad por el coronavirus de 2019 (COVID-19) secundaria a SARS-CoV-2 y la diabetes mellitus es bidireccional. Por un lado, la diabetes mellitus se asocia con un mayor riesgo de COVID-19 grave. Por otro lado, en pacientes con COVID-19 se han observado diabetes mellitus de nueva aparición con presentaciones de cetoacidosis diabética y complicaciones metabólicas graves de dicha presentación. CASOS CLÍNICOS: En este informe, describimos a dos pacientes pediátricos con diabetes mellitus que acudieron a nuestro hospital con cetoacidosis diabética, de debut inicial. Describimos la evolución y el manejo clínico y terapéutico durante la pandemia de COVID-19. CONCLUSIÓN: La infección por COVID-19 puede precipitar complicaciones como cetoacidosis diabética severa.

INTRODUCTION: Coronavirus 2019 (SARS-CoV-2) infection in children occurred in Peru as of March 2020, leading to pediatric patients' hospitalization in areas adapted for this purpose at the Edgardo Rebagliati Martins National Hospital. In the beginning, the demand for hospitalization was low, but it increased gradually. Consistent with international reports, the majority of patients presented mild or moderate symptoms. Nonetheless, there were also severe cases, even fatal ones. OBJECTIVES: To describe the characteristics and clinical outcome of pediatric patients with COVID-19 hospitalized in a referral hospital in Lima, Peru, between March and August 2020. METHODS: A descriptive and inferential cross-sectional study was carried out. The population includes all hospitalized patients in the Department of Pediatrics, with clinical and surgical diagnoses associated with COVID-19. RESULTS: We included 100 patients, with an average age of 83.4 ± 54 months, with a predominance of male patients (55%). Hospitalized patients were grouped into five categories: respiratory failure (17%), multisystemic inflammatory syndrome (MIS-C) (31%), neurological presentation (19%), acute abdomen (20%), and patients with oncological problems (13%). Most of the patients (74%) had comorbidities. Regarding the presenting symptoms, intestinal pain predominated in the appendicitis group (90%, p < 0.001), fever was present in most patients with respiratory failure (64.7%); multisystemic inflammatory syndrome (90.3%), neurological manifestations (15.8%), acute abdomen (50%) and oncological conditions (61.5%) were also present in these patients. Kawasaki symptoms were found in 38.7% of the patients with multisystemic inflammatory syndrome. Mortality was 4%. Respiratory problems (29.4%) and multisystemic inflammatory syndrome (22.6%) required admission to intensive care, more frequently than the other presentations (p = 0.008). CONCLUSIONS: We conclude that the vulnerability in the pediatric population is the one that has preexisting conditions. We divided our patients according to presentation, diagnosis, and complications, which were predominantly respiratory. We also had oncological patients with COVID-19.
INTRODUCCIÓN: La infección por coronavirus 2019 (SARS-CoV-2) en niños se presentó en Perú desde marzo del 2020. Desde entonces fue necesario internar pacientes pediátricos en el Hospital Nacional Edgardo Rebagliati Martins, en el área de hospitalización adaptada para dicho propósito. Al inicio, la demanda de hospitalización era baja y se fue incrementando progresivamente. Coincidiendo con los reportes internacionales, la mayoría presentó cuadros leves o moderados, pero también hubo casos graves e incluso mortales. OBJETIVOS: Describir las características y el desenlace clínico de los pacientes pediátricos con COVID-19 hospitalizados en un hospital de referencia en Lima, Perú, entre marzo y agosto de 2020. MÉTODOS: Se realizó un estudio transversal descriptivo e inferencial. La población incluyó a todos los pacientes que se hospitalizaron en el Departamento de Pediatría Clínica, con diagnósticos clínicos y quirúrgicos asociados a COVID-19. RESULTADOS: Incluimos 100 pacientes, con edad promedio de 83,4 ± 54 meses, con predominio de varones (55%). Los pacientes hospitalizados fueron agrupados en cinco categorías: insuficiencia respiratoria (17%), síndrome inflamatorio multisistémico (31%), presentación neurológica (19%), abdomen agudo (20%) y pacientes con problemas oncológicos (13%). La mayoría de los pacientes (74%) tenían comorbilidades. Respecto a los síntomas de presentación, el dolor intestinal predominó en el grupo de apendicitis (90%, p < 0,001), la fiebre estuvo presente en la mayoría de los pacientes con falla respiratoria (64,7%), el síndrome inflamatorio multisistémico se registró en 90,3%, la sintomatología neurológica en 15,8%, el abdomen agudo 50% y oncológicos en 61,5% de los pacientes. Los síntomas de Kawasaki estuvieron presentes en 38,7% de los pacientes con síndrome inflamatorio multisistémico. La mortalidad fue de 4%. En 29,4% de problemas respiratorios y en 22,6% de síndrome inflamatorio multisistémico, se requirió de admisión en cuidados intensivos, lo que fue más frecuente que las otras presentaciones (p = 0,008). CONCLUSIONES: Se concluye que la población pediátrica vulnerable es aquella con comorbilidades preexistentes. La división de pacientes en nuestro estudio fue definida por la presentación, diagnóstico y complicaciones predominantemente con problemas respiratorios, y en pacientes oncológicos con COVID-19.

Abstract Pediatric acute respiratory distress syndrome (PARDS) is a frequent diagnosis in critical care. This inflammatory process has different stages characterized by mild-to-severe hypoxia, and the management will vary according to the severity. New definitions for pediatric patients were published in 2015; new epidemiological evidence revising those definitions has helped understand the mortality associated with PARDS and the impact on ventilation. The strategies to protect the lungs during mechanical ventilation have been successful in reducing mortality and complications. In clinical situations where high levels of critical support are limited, other therapies with a lower level of evidence can be attempted to gain time without worsening the ongoing pulmonary injury. We offer a complete narrative revision of this syndrome, with the critical management of these patients as a priority.
Resumen El síndrome de dificultad respiratoria aguda pediátrica (SDRAP) es un diagnóstico frecuente en cuidados intensivos. Este proceso inflamatorio se caracteriza por diferentes grados de hipoxia, de leve a grave, y el manejo varía de acuerdo con la gravedad. En 2015 se publicaron nuevas definiciones para pacientes pediátricos, así como nueva evidencia epidemiológica, que toma como punto de partida dichas definiciones, lo cual ha ayudado a entender la mortalidad asociada y el impacto del manejo ventilatorio con respecto a la morbilidad en este síndrome. Las estrategias que protegen los pulmones durante la ventilación mecánica han sido exitosas en reducir la mortalidad y las complicaciones subsecuentes. En situaciones en las que existen limitaciones que impiden suministrar altos niveles de soporte crítico se pueden implementar otras medidas de menor evidencia para ganar tiempo e impedir que se extiendan las lesiones pulmonares. A continuación, se ofrece una revisión narrativa completa de este síndrome, con un enfoque que prioriza el manejo crítico de estos pacientes.
