Post-artesunate delayed hemolysis (PADH) occurred in 6 of 24 children treated with artesunate for severe malaria in the United States; however severe hemolysis requiring hospitalization or transfusion was rare. In children in the U.S. treated with artesunate, counseling and symptom monitoring may be preferred to weekly laboratory surveillance for PADH.

A large proportion of children have been affected by COVID-19; we evaluated the association between comorbidities and hospitalization/ICU (intensive care unit) admission among 4097 children under age 21 years with symptomatic COVID-19 (not just polymerase chain reaction [PCR]-positive or multisystem inflammatory syndrome in children associated with COVID-19 [MIS-C]) from 2 large health systems from March 2020 to September 2021. Significant comorbidities and demographic factors identified by univariable analysis were included in a multivariable logistic regression compared with children ages 6 to 11 without comorbidities. In all, 475 children (11.6%) were hospitalized, of whom 25.5% required ICU admission. Children under 1 year had high hospitalization risk, but low risk of ICU admission. Presence of at least 1 comorbidity was associated with hospitalization and ICU admission (odds ratio [OR] > 4). Asthma, obesity, chronic kidney disease, sickle cell disease, bone marrow transplantation, and neurologic disorders were associated with hospitalization (adjusted odds ratio [AOR] > 2). Malignancy, intellectual disability, and prematurity were associated with ICU admission (AOR > 4). Comorbidities are significantly associated with hospitalization/ICU admission among children with COVID-19.

Pediatricians and adolescent providers play an important role in the health and well-being of adolescents and young adults, including their sexual health. HIV remains an ongoing concern for young people, with 21% of new HIV diagnoses occurring in this age group. The use of antiretroviral therapy for pre-exposure prophylaxis (PrEP) to prevent transmission of HIV to people who are not infected has been proven safe and effective. PrEP can be considered as part of a comprehensive risk mitigation strategy for adolescents and young adults, with clear guidelines for baseline evaluation and ongoing management.

Importance/UNASSIGNED:To date, no study has characterized the mucocutaneous features seen in hospitalized children with multisystem inflammatory syndrome in children (MIS-C) or the temporal association of these findings with the onset of systemic symptoms. Objective/UNASSIGNED:To describe the mucocutaneous findings seen in children with MIS-C during the height of the coronavirus disease 2019 (COVID-19) pandemic in New York City in 2020. Design, Setting, and Participants/UNASSIGNED:A retrospective case series was conducted of 35 children admitted to 2 hospitals in New York City between April 1 and July 14, 2020, who met Centers for Disease Control and Prevention and/or epidemiologic criteria for MIS-C. Main Outcomes and Measures/UNASSIGNED:Laboratory and clinical characteristics, with emphasis on mucocutaneous findings, of children who met criteria for MIS-C. The characterization of mucocutaneous features was verified by 2 board-certified pediatric dermatologists. Results/UNASSIGNED:Twenty-five children (11 girls [44%]; median age, 3 years [range, 0.7-17 years]) were identified who met definitional criteria for MIS-C; an additional 10 children (5 girls [50%]; median age, 1.7 years [range, 0.2-15 years]) were included as probable MIS-C cases (patients met all criteria with the exception of laboratory test evidence of severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] infection or known exposure). The results of polymerase chain reaction tests for SARS-CoV-2 were positive for 10 patients (29%), and the results of SARS-CoV-2 immunoglobulin G tests were positive for 19 patients (54%). Of the 35 patients, 29 (83%) exhibited mucocutaneous changes, with conjunctival injection (n = 21), palmoplantar erythema (n = 18), lip hyperemia (n = 17), periorbital erythema and edema (n = 7), strawberry tongue (n = 8), and malar erythema (n = 6) being the most common findings. Recognition of mucocutaneous findings occurred a mean of 2.7 days (range, 1-7 days) after the onset of fever. The duration of mucocutaneous findings varied from hours to days (median duration, 5 days [range, 0-11 days]). Neither the presence nor absence of mucocutaneous findings was significantly associated with overall disease severity. Conclusions and Relevance/UNASSIGNED:In this case series of hospitalized children with suspected MIS-C during the COVID-19 pandemic, a wide spectrum of mucocutaneous findings was identified. Despite their protean and transient nature, these mucocutaneous features serve as important clues in the recognition of MIS-C.

PURPOSE OF REVIEW/OBJECTIVE:Here we summarize current knowledge about multisystem inflammatory syndrome in children (MIS-C), a presumed postinfectious inflammatory condition that has emerged as an important COVID-19-associated complication, to help clinicians identify and manage cases. RECENT FINDINGS/RESULTS:Clinical presentation of MIS-C is dominated by significant inflammation. Fever, gastrointestinal symptoms, cardiac dysfunction, and hypotension are common features. Kawasaki disease-like findings are common, but epidemiologic data and recent mechanistic studies suggest that distinct inflammatory pathways mediate Kawasaki disease and MIS-C. A broad diagnostic approach is recommended, given overlapping presentations between MIS-C and many other disease processes. Current management of MIS-C is highly variable, depending on illness severity, and can range from supportive care to aggressive immune modulation. A multidisciplinary approach with early involvement of multiple pediatric subspecialists is recommended for complicated cases. SUMMARY/CONCLUSIONS:Several studies have described the clinical manifestations of MIS-C, but definitive diagnosis remains challenging. Robust information about long-term outcomes awaits further study, as do immunologic data to refine diagnostic and therapeutic strategies.

We report two cases of SARS-CoV-2 infection (COVID-19) in infants presenting with fever in the absence of respiratory distress who required hospitalization for evaluation of possible invasive bacterial infections. The diagnoses resulted from routine isolation and real-time RT-PCR-based testing for SARS-CoV-2 for febrile infants in an outbreak setting.

A 17-year-old obese male was admitted to the pediatric intensive care unit after presenting with fluid-responsive septic shock following 7 days of fever, gastrointestinal symptoms and neck pain. Initial workup was positive for SARS-CoV-2 and elevated troponin I and brain natriuretic peptide. Echocardiography and cardiac magnetic resonance imaging confirmed acute myocarditis. One week after discharge, repeat echocardiogram demonstrated improved heart function with only residual myocardial dysfunction.

We present a paediatric case of group G streptococcal bacteraemia and vertebral osteomyelitis. The patient is a 14-year-old girl with Gaucher disease type 1 who presented with severe thoracolumbar pain. She was treated with a 4-week course of antibiotics for presumed osteomyelitis with clinical improvement.
