Abstract
BACKGROUND:Listeriosis may cause severe disease in fetuses and neonates. The outcomes of critically ill neonates with early-onset listeriosis requiring extracorporeal membrane oxygenation (ECMO) from 1975 to 1991 have been reported. OBJECTIVE:To update the characteristics and outcomes of neonates with listeriosis supported by ECMO. STUDY DESIGN:Retrospective study of neonates with culture-proven listeriosis reported to the Extracorporeal Life Support Organization Registry between 1991 and 2017. Comparisons were made between this cohort and the case series from 1975-1991. RESULTS:Twenty-two neonates had culture-proven Listeria monocytogenes infection and required ECMO support. Eight-six percent survived to discharge, compared with 67% in the previous cohort (p = 0.2). The median ECMO duration was 131 h, compared with 209 h in the previous cohort (p = 0.1). Nonsurvivors had a significantly lower pre-ECMO pH (6.91 vs 7.31, p = 0.0006). CONCLUSION:The survival of neonates with listeriosis supported with ECMO is high, supporting the use of ECMO as rescue therapy for this condition.
摘要
背景: 李斯特菌病可引起胎儿和新生儿的严重疾病。报道了 1975年至 1991年需要体外膜肺氧合 (ECMO) 的早发型李斯特菌病危重新生儿的结局。 目的: 更新 ECMO 支持下新生儿李斯特菌病的特点和转归。 研究设计: 2017 和 1991年向体外生命支持组织登记处报告的培养证实的李斯特菌病新生儿的回顾性研究。比较该队列与 1975-1991 病例系列。 结果: 22 例新生儿培养证实为单核细胞增生李斯特菌感染,需要 ECMO 支持。8-6% 存活至出院,而上一队列为 67% (p = 0.2)。中位 ECMO 持续时间为 131 h,而上一队列为 209 h (p = 0.1)。非存活者 ECMO 前 pH 显著降低 (6.91 vs 7.31,p = 0.0006)。 结论: ECMO 支持的李斯特菌病新生儿存活率高,支持 ECMO 作为抢救治疗。

METHODS:INTRODUCTION:Continuous albuterol is a mainstay in management of pediatric status asthmaticus. While the National Heart Lung and Blood Institute Asthma Guidelines suggest 0.5 mg/kg/hr as the recommended dosage, there is a paucity of evidence comparing different weight based rates on hospital outcomes. METHODS:Patients requiring continuous albuterol for asthma exacerbation from January 2015 to December 2016 were identified using ICD codes. The concentration of albuterol (5 mg/h - 20 mg/h) and the duration of treatment were used to determine total albuterol administration. After dividing by patient weight, average weight based doses were divided into equal quintiles. Unadjusted and length of stay adjusted for age, initial asthma severity score, and administration of magnesium were compared among the quintiles. The same multivariate analysis was used for duration of continuous albuterol. RESULTS:533 hospitalizations for asthma were identified of which 289 received continuous albuterol. Weight based dosage quintiles ranged from lowest (0.07 - 0.29 mg/kg/hr) to the highest (>0.76 - 3.2 mg/kg/hr). Baseline characteristics were similar aside from age, race, and magnesium administration. There was no difference in adjusted length of stay or adjusted duration of continuous albuterol therapy among the five quintiles. CONCLUSION:No optimal weight based dose of continuous albuterol was found. Further investigation is needed to see if lower amounts of continuous albuterol may be as efficacious as higher doses. This could improve cost of status asthmaticus management and limit the number of adverse events associated with high exposure to continuous albuterol.
METHODS:Abstract Background We investigated the association between a combination of two markers, peripheral (PEC) and bronchoalveolar lavage (BAL) eosinophil percentage (BEP), and oxygen requirements in patients with acute eosinophilic pneumonia (AEP). Methods We retrospectively reviewed the medical records of patients with AEP treated at the Armed Forces Capital Hospital between May 2012 and May 2017. We used correlation analyses to assess the association between PEC/BEP and clinical outcomes in AEP patients. Receiver operating characteristic (ROC) curve analyses were used to calculate the cut-off value for BEP that categorised patients requiring a significant oxygen supply. The BAL/blood eosinophil (BBE) score was introduced to stratify patients with peripheral eosinophilia and elevated BEP. Clinical characteristics and outcomes were compared between the different groups. Multiple logistic regression was performed for significant oxygen requirements using two different models using age, C-reactive protein (CRP), smoking duration, and BBE score (model 1) and age, CRP, BEP, and PEC (model 2). Results Among the 338 patients, 99.7% were male, and their mean age was 20.4 ± 1.4 years. Only 0.6% of patients were never smokers and the mean number of smoking days was 26.2 ± 25.4. Correlation analyses revealed that both the PaO2/FiO2 ratio and duration of oxygen supply were associated with BEP. ROC curve analyses indicated a cut-off level of 41.5%. Patients with a high BBE score had favourable outcomes in terms of hypoxemia, hospital days, intensive care unit admission, oxygen supply days, and steroid treatment days. Multiple logistic regression revealed that BEP and BBE score tended to be associated with significant oxygen requirements. Conclusions In this study, we revealed that both peripheral and BAL eosinophilia is associated with favourable outcomes in AEP patients.
METHODS:Background. Extensive studies have focused on the diagnosis and treatment of Mycoplasma pneumoniae infection; however, rare studies investigated the posttreatment conditions. We analyzed the carrying status of M. pneumoniae in the respiratory tract of children before and after treatment. Methods. Ninety-two children with M. pneumoniae pneumonia were included in this study. Clinical data were obtained from each patient, and pharyngeal swab sampling was performed at preliminary diagnosis and discharge. Real-time PCR and dilution quantitative culture were utilized to determine the DNA quantification and number of viable M. pneumoniae from samples collected upon preliminary diagnosis and discharge. Results. All the 92 cases showed DNA positivity upon preliminary diagnosis, serum IgM antibody was detected in 80 patients, and positivity of M. pneumoniae culture was observed in 82 cases. Upon discharge, the M. pneumoniae nucleotide and culture positivity were detected in 87 and 49 cases, respectively. The content of viable M. pneumoniae was 10–104 CCU/mL and 10–102 CCU/mL in the preliminary diagnosis samples and discharge samples, respectively. Conclusions. Real-time PCR was rapid and effective for the qualitative diagnosis of M. pneumoniae at the early stage, but it cannot be used to evaluate the prognosis of patients with M. pneumoniae infection. Quantitative analysis for M. pneumoniae DNA could not directly reflex the viable strain content.
