    查看更多>>摘要:Background Recent infection with SARS-CoV-2 in children has been associated with multisystem inflammatory syndrome in children(MIS-C).SARS-CoV-2 has undergone different mutations.Few publications exist about specific variants and their correlation with the severity of MIS-C.Methods This was a single-center,retrospective study including all patients admitted with MIS-C at Rady Children's Hospital-San Diego between May 2020 and March 2022.Local epidemiologic data,including viral genomic information,were obtained from public records.Demographics,clinical presentation,laboratory values,and outcomes were obtained from electronic medical records.Results The analysis included 104 pediatric patients.Four MIS-C waves were identified.Circulating variants in San Diego during the first wave included clades 20A to C.During the second wave,there were variants from clades 20A to C,20G,21C(Epsilon),201(Alpha),and 20J(Gamma).The third wave had Delta strains(clades 21 A,211,and 21 J),and the fourth had Omicron variants(clades 2 1K,21L,and 22C).MIS-C presented with similar symptoms and laboratory findings across all waves.More patients were admitted to the pediatric intensive care unit(PICU)(74%)and required inotropic support(63%)during the second wave.None of the patients required mechanical circulatory support,and only two required invasive ventilatory support.There was no mortality.Conclusions The various strains of SARS-CoV-2 triggered MIS-C with differing severities,with the second wave having a more severe clinical course.Whether the differences in disease severity across variants were due to changes in the virus or other factors remains unknown.

    查看更多>>摘要:Background Macrophages are involved in various immune inflammatory disease conditions.This study aimed to investigate the role and mechanism of macrophages in regulating acute intestinal injury in neonatal necrotizing enterocolitis(NEC).Methods CD68,nucleotide-binding oligomerization domain,leucine-rich repeat,and pyrin domain-containing 3(NLRP3),cysteine aspartate-specific protease-1(caspase-1),and interleukin-1β(IL-1 β)in paraffin sections of intestinal tissues from NEC and control patients were detected with immunohistochemistry,immunofluorescence,and western blot.Hypertonic pet milk,hypoxia and cold stimulation were used to establish a mouse(wild type and Nlrp3-/-)model of NEC.The mouse macrophage(RAW 264.7)and rat intestinal epithelial cell-6 lines were also cultured followed by various treatments.Mac-rophages,intestinal epithelial cell injuries,and IL-1β release were determined.Results Compared to the gut"healthy"patients,the intestinal lamina propria of NEC patients had high macrophage infil-tration and high NLRP3,caspase-1,and IL-1β levels.Furthermore,in vivo,the survival rate of Nlrp3/-NEC mice was dramatically improved,the proportion of intestinal macrophages was reduced,and intestinal injury was decreased compared to those of wild-type NEC mice.NLRP3,caspase-1,and IL-1β derived from macrophages or supernatant from cocultures of macrophages and intestinal epithelial cells also caused intestinal epithelial cell injuries.Conclusions Macrophage activation may be essential for NEC development.NLRP3/caspase-1/IL-1β cellular signals derived from macrophages may be the underlying mechanism of NEC development,and all these may be therapeutic targets for developing treatments for NEC.

    查看更多>>摘要:Background Necrotizing enterocolitis(NEC)is the most common severe gastrointestinal emergency in neonates.We designed this study to identify the pathogenic microorganisms of NEC in the microbiota of the small intestine of neonates.Methods Using the 16S ribosomal DNA(rDNA)sequencing method,we compared and analyzed the structure and diversity of microbiotas in the intestinal feces of different groups of neonates:patients undergoing jejunostomy to treat NEC(NP group),neonates undergoing jejunostomy to treat other conditions(NN group),and neonates with NEC undergoing conserva-tive treatment(NC group).We took intestinal feces and saliva samples from patients at different time points.Results The beta diversities of the NP,NN,and NC groups were all similar.When comparing the beta diversities between different time points in the NP group,we found similar beta diversities at time points El to E3 but significant differences between the E2-E3 and E4 time points:the abundances of Klebsiella and Enterococcus(Proteobacteria)were higher at the E1-E3 time points;the abundance of Escherichia-Shigella(Proteobacteria)increased at the E2 time point,and the abundance of Klebsiella decreased significantly,whereas that of Streptococcus increased significantly at the E4 time point.Conclusions Our results suggest that the pathological changes of intestinal necrosis in the small intestine of infants with NEC are not directly caused by excessive proliferation of pathogenic bacteria in the small intestine.The sources of microbiota in the small intestine of neonates,especially in premature infants,may be affected by multiple factors.

    查看更多>>摘要:Background Tetralogy of Fallot(TOF)is the most common cyanotic congenital heart disease.Children with TOF would be confronted with neurological impairment across their lifetime.Our study aimed to identify the risk factors for cerebral morphology changes and cognition in postoperative preschool-aged children with TOF.Methods We used mass spectrometry(MS)technology to assess the levels of serum metabolites,Wechsler preschool and primary scale of intelligence-Fourth edition(WPPSI-Ⅳ)index scores to evaluate neurodevelopmental levels and multimodal magnetic resonance imaging(MRI)to detect cortical morphological changes.Results Multiple linear regression showed that preoperative levels of serum cortisone were positively correlated with the gyrification index of the left inferior parietal gyrus in children with TOF and negatively related to their lower visual spaces index and nonverbal index.Meanwhile,preoperative SpO2 was negatively correlated with levels of serum cortisone after adjusting for all covariates.Furthermore,after intervening levels of cortisone in chronic hypoxic model mice,total brain volumes were reduced at both postnatal(P)11.5 and P30 days.Conclusions Our results suggest that preoperative serum cortisone levels could be used as a biomarker of neurodevelopmen-tal impairment in children with TOF.Our study findings emphasized that preoperative levels of cortisone could influence cerebral development and cognition abilities in children with TOF.
