In December 2019, the 2019 novel coronavirus disease (COVID‐19) caused by Severe Acute Respiratory Syndrome Coronavirus‐2 (SARS‐CoV‐2) first emerged in Wuhan, China. This has now spread worldwide and was declared a pandemic by March 2020. Initially, the pediatric population was described as low risk for severe COVID‐19. However, reports have emerged recently of cases of COVID‐19 in children with a systemic inflammatory disease, with features that overlap with Kawasaki Disease (KD). We describe the first 15 cases with multi‐system inflammatory syndrome in children (MIS‐C), temporally related to COVID‐19, who presented for care to a tertiary pediatric referral center in New York City. We discuss the disproportionate burden of disease among Hispanic/Latino and black/African‐American ancestry, the distinct cytokine signature across the disease spectrum (IL‐1/IL‐6), and the potential role and pathogenesis of SARS‐CoV‐2 in this new clinical entity.

Background/Rationale: Early-onset neonatal sepsis (EOS) is often acquired through vertical transmission and is an important cause of morbidity and mortality in infants. The etiology of neonatal sepsis has changed over time, and the intrapartum management of women at risk for infection has been shown to improve neonatal outcomes. Hypothesis or Research Question:To identify the microbiologic etiology of organisms causing EOS and evaluate the impact of maternal illness, labor and delivery practices, and postnatal factors on EOS rates at Mount Sinai Hospital (MSH).Study Design/Methods: An IRB approved descriptive retrospective chart review of cases of EOS in infants less than 7 days of age at MSH from 2015-2018 was conducted. A total of 41 infants were identified. Clinical charts were reviewed and classified into two groups based on age at time of presentation: very early onset sepsis (VEOS) (age days 0-2) and delayed early onset sepsis (DEOS) (age days 3-7). Corresponding maternal charts were also reviewed to identify obstetric risk factors and whether at-risk mothers received appropriate intrapartum prophylaxis.Results: In the VEOS group, 41% of cases were caused by Group B Streptococcus (GBS), 30% by E.coli, and 18% by other Streptococci. In the DEOS group, 33% of cases were coagulase-negative Staphylococci, 27% E.coli, and 20% S. aureus. There were no cases of GBS among the DEOS group. On average, VEOS occurred in term infants (37.40 ± 4.41 weeks) with a normal weight (2840 ± 88g), while DEOS occurred in preterm infants (30.74 ± 6.08 weeks) with a low birth weight (1550 ± 104g). 36.4% of GBS isolates demonstrated resistance to clindamycin. E.coli isolates demonstrated resistance to ampicillin/sulbactam (66.7%), co-trimoxazole (41.7%), and gentamicin (35%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
