Abstract
BACKGROUND Vancomycin is a glycopeptide antibiotic that has been used to treat hospital-acquired gram-positive infections for more than 5 decades. However, the literature is divided regarding the therapeutic advantages of vancomycin loading doses in neonates. OBJECTIVES This study aimed to investigate the effect of vancomycin loading doses on therapeutic target attainment in neonates with sepsis. METHODS A retrospective cohort study was conducted to compare the vancomycin target attainment (area under the curve 0-24 hours/minimum inhibitory concentration ≥400) in neonates before and after the 2019 change in vancomycin prescription guidelines at a neonatal unit in Cape Town, South Africa. As the standard of care, Bayesian modelling software was used to compute the area under the curve from the trough concentrations. RESULTS Two hundred ten neonates were included. Multivariate regression analysis showed a 2-fold increase in the odds of target attainment among neonates receiving a loading dose of vancomycin. Early target attainment (within 8-12 hours of treatment initiation) was significantly higher in the loading dose group compared with the no loading dose group [97/105 (92.4%) versus 64/105 (61.0%); P < 0.001]. However, the overall proportion of neonates achieving target attainment at 24 hours was similar between groups [73/105 (69.5%) in the loading dose group versus 62/105 (59.0%) in the no loading dose group; P = 0.110]. The nephrotoxicity rates were low [2/105 (1.9%) in the loading dose group and 2/105 (1.9%) in the no loading dose group]. CONCLUSIONS The addition of a vancomycin loading dose to neonates may facilitate early therapeutic target attainment.

Abstract
OBJECTIVE Lumbar punctures are performed as part of a routine evaluation of neonates with fever in the emergency department. Current recommendations regarding performing a lumbar puncture in the presence of thrombocytopenia exist for children with leukemia and other cancers; however, there are no such recommendations for the general neonatal population. This study assesses the frequency of thrombocytopenia and adverse bleeding events in neonates who undergo a lumbar puncture to determine whether a complete blood count, and specifically the platelet count, should be reviewed before performing the lumbar puncture. METHODS This is a retrospective chart review of neonates 30 days or younger presenting to a single freestanding pediatric emergency department who received a lumbar puncture over the course of 11 years. The complete blood count was reviewed for thrombocytopenia, determined to be platelet count of less than 150,000/μL. The chart was reviewed for any documented adverse bleeding events associated with the lumbar puncture. RESULTS A total population of 2145 was studied with 56 patients determined to be thrombocytopenic. Seven total bleeding events were identified: 1 in the thrombocytopenic group and 6 in the nonthrombocytopenic group. All bleeding events were deemed to be clinically significant, either resulting in prolonged hospital stay or required further workup and medical intervention. The percentage of clinically adverse bleeding events that were related to the lumbar puncture was 0 (0.0%; 95% confidence interval, 0.0%-6.4%) and 2 (0.1%; 95% confidence interval, 0.0%-0.3%) ( P = 1.0) in the thrombocytopenic and nonthrombocytopenic groups, respectively. CONCLUSIONS Our results demonstrated a very low risk of bleeding events associated with lumbar punctures in neonates, with no increased risk in the thrombocytopenic group. As such, we conclude that waiting for the results of a complete blood count before performing the lumbar puncture in neonates without a known bleeding disorder is unnecessary.

Cord blood presepsin as a predictor of early-onset neonatal sepsis in term and preterm newborns. Ital J Pediatr 2023; 49:35. [PMID: 36945009 PMCID: PMC10029283 DOI: 10.1186/s13052-023-01420-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 01/25/2023] [Indexed: 03/23/2023] Open
Abstract
BACKGROUND To date, no studies on presepsin values in cord blood of term infants with risk factors for early-onset sepsis (EOS) are available, whereas only one study reported presepsin values in cord blood of preterm infants at risk. In this study, we investigated the presepsin values in cord blood of term and preterm infants with documented risk factors for EOS. METHODS In this single-center prospective pilot study, we enrolled neonates presenting with documented risk factors for EOS. P-SEP levels were assessed in a blood sample collected from the clamped umbilical cord after the delivery in 93 neonates, using a point-of-care device. The primary outcome of our study was to evaluate the role of cord blood P-SEP in predicting clinical EOS in term and preterm infants. RESULTS During the study period, we enrolled 93 neonates with risk factors for EOS with a gestational age ranging between 24.6 and 41.6 weeks (median 38.0). The median P-SEP value in all infants was 491 pg/ml (IQR 377 - 729). Median cord P-SEP values were significantly higher in infants with clinical sepsis (909 pg/ml, IQR 586 - 1307) rather than in infants without (467 pg/ml, IQR 369 - 635) (p = 0.010). We found a statistically significant correlation between cord P-SEP value at birth and the later diagnosis of clinical sepsis (Kendall's τ coefficient 0.222, p = 0.002). We identified the maximum Youden's Index (best cut-off point) at 579 pg/ml, corresponding to a sensitivity of 87.5% and a specificity of 71.8% in predicting clinical sepsis. CONCLUSIONS Maximum Youden's index was 579 pg/ml for clinical EOS using cord P-SEP values. This could be the starting point to realize multicenter studies, confirming the feasibility of dosing P-SEP in cord blood of infants with risk factors of EOS to discriminate those who could develop clinical sepsis and spare the inappropriate use of antibiotics.

Acta Paediatr 2022; 111:992-1001.

Abstract
AIM We examined community and hospital-acquired bacteraemia, namely bloodstream infections or meningitis, and looked at the clinical features and outcomes of cases. METHODS The study comprised infants under 3 months of age, who were admitted to a tertiary referral centre in northern Israel with bacteraemia from 2010-2019. Causative pathogens, antibiotic susceptibility and mortality were retrospectively recorded. RESULTS We identified 314 infants, 325 episodes of bacteraemia and 344 pathogens. Meningitis was identified in 22 (7.0%) infants. Hospital-acquired bacteraemia accounted for 84.8% of the 325 episodes. Coagulase-negative staphylococci (33.9%) was the most prevalent pathogen in the hospital-acquired cases, while Escherichia coli (37.2%) dominated the community-acquired cases. The susceptibility of Gram-negative early-onset sepsis cases to ampicillin-gentamicin or ampicillin-cefotaxime was 96% and 94.7% for hospital-acquired cases and 91.7% and 88% for community-acquired cases, respectively. Susceptibility to piperacillin-tazobactam or amikacin in late-onset sepsis were 92.8% and 98%, respectively, in hospital-acquired cases. The 30-day mortality was 5.7% in infants with hospital-acquired cases. Risk factors were Arab ethnicity (p < 0.028), haemodynamic instability (<0.001) and Gram-negative sepsis (0.043). CONCLUSION Most cases of bacteraemia were acquired during hospitalisation and these accounted for the majority of the deaths. Resistance to standard antibiotic regimens was rare.
