Background: C‐reactive protein (CRP) has limited placental transportability. Relying on CRP level in umbilical cord blood alone is an inaccurate way to predict early onset neonatal sepsis, and we retrospectively reviewed the clinical courses of neonates with elevated CRP in umbilical cord blood. Methods: This study was a retrospective case review of neonates with elevated CRP in umbilical cord blood (>0.5 mg/dL) in the Nara Prefecture General Medical Center, Nara, Japan between February 2013 and August 2017. We investigated the association of maternal and neonatal factors with neonatal clinical course. Then, we compared the cases of neonates with and without elevated CRP in umbilical cord blood. Results: The subjects consisted of a total of 22 neonates with elevated CRP in umbilical cord blood and 344 neonates without elevated CRP in umbilical cord blood. Of the 22 neonates with elevated CRP, 18 had some symptoms of sepsis at birth, but the symptoms of 85% of the symptomatic patients resolved ≤24 h after birth. Two neonates with elevated CRP in umbilical cord blood had bacteremia, and they had poor prognoses. Elevated CRP in umbilical cord blood was associated with length of antimicrobials (P = 0.021), immature/total neutrophil ratio (P = 0.017), and pathological chorioamnionitis (CAM; P = 0.028) on multivariable logistic regression analysis. Conclusion: Elevated CRP in umbilical cord blood was associated with pathological CAM. Most symptoms of sepsis resolved <24 h after birth. [ABSTRACT FROM AUTHOR]

Abstract: Background: Routine catheter tip cultures are not recommended because some cases of colonization, such as with Staphylococcus aureus, can lead to subsequent bacteremia. To evaluate the safety of colonization without antimicrobial treatment, as well as the effectiveness of routine catheter tip cultures in the neonatal intensive care unit (NICU), we performed a retrospective data analysis in a Japanese community hospital. Methods: We reviewed all peripherally inserted central venous catheter tip culture results from the NICU ward between April 2012 and June 2017 and noted outcome (i.e. antimicrobial treatment or subsequent infection). We then performed a cost analysis for routine catheter tip culturing on patients who were symptom free during the study period. Results: Of the 93 positive cases in 80 patients from 1,051 catheter tip cultures, seven patients had suspected infection and were treated with antimicrobials. The other 73 symptom‐free, positive patients had no subsequent or exacerbated symptoms indicative of an infection, and did not have antimicrobial treatment. The total cost for catheter tip culturing during the study period was ¥548 731. After excluding patients with symptoms of infection at the time of culture, the efficacy of routine catheter tip cultures on symptom‐free patients was estimated to be zero. Conclusion: Symptom‐free colonization did not affect clinician management in this study, and all colonized patients without suspected infection were safely managed without antimicrobials. Furthermore, routine catheter tip culturing was not cost‐effective; therefore, this practice may be no longer recommended in the NICU. [ABSTRACT FROM AUTHOR]
