Acta Paediatr 2023; 112:726-733. [PMID: 36740931 DOI: 10.1111/apa.16701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 01/24/2023] [Accepted: 02/03/2023] [Indexed: 02/07/2023]
Abstract
AIM The aim of the study was to examine the predictive value of inflammatory markers for chorioamnionitis and funisitis in extremely low gestational age neonates. METHODS According to the Redline histopathological classification, extremely low gestational age neonates were classified into: (1) maternal inflammatory response ≤1 or ≥2, based on inflammatory findings of the placenta and (2) foetal inflammatory response ≤1 or ≥2, based on inflammatory findings of the umbilical cord. On admission and 12-36 h postnatally, procalcitonin and high-sensitivity C-reactive protein levels and white blood cell and neutrophil counts were compared. For both maternal and foetal inflammatory responses ≥2, the predictive value of each inflammatory marker was calculated. RESULTS On admission, procalcitonin had the best predictive value for maternal and foetal inflammatory response ≥2. The maternal inflammatory response ≥2 prediction score includes procalcitonin level on admission, high-sensitivity C-reactive protein level and white blood cell count at 12-36 h postnatally. Foetal inflammatory response ≥2 prediction score includes procalcitonin level and white blood cell count on admission and 12-36 h postnatally. The sensitivities were 96.4% and 96.3%, respectively. CONCLUSION Procalcitonin, high-sensitivity C-reactive protein levels and white blood cell count provide highly sensitive prediction scores for chorioamnionitis and funisitis in extremely low gestational age neonates.

[PMID: 35795229 PMCID: PMC9251195 DOI: 10.3389/fsurg.2022.899795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 05/31/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose To analyze the obstetric high-risk factors and serological characteristics of early-onset neonatal bacterial infections (EONBI). Methods 119 neonates with early-onset bacterial infection who were admitted to the neonatal ward of our hospital from October 2020 to December 2021 were recorded as the study group, and 100 neonates without bacterial infection who were admitted during the same period were used as the reference group. Comparative analysis of obstetric high-risk factors and serological characteristics of EONBI. Results There was no statistical difference between the two groups in terms of gender and age at admission (P > 0.05). The gestational age and birth weight of newborns in the study group were lower than those in the reference group (P < 0.001). Comparing the maternal factors of EONBI between the two groups, there was no statistical difference in age, number of obstetric inspections, whether to use antibiotics, and mode of delivery (P > 0.05). Univariate analysis showed that preterm birth, unexplained asphyxia, fecal contamination of amniotic fluid, maternal infection during pregnancy, and premature rupture of membranes ≥18 h were significantly associated with EONBI (P < 0.05); while there was no significant difference between the two groups in the comparison between diabetic mother and child and maternal fever at delivery (P > 0.05). Multifactorial analysis showed that preterm birth, fecal contamination of amniotic fluid, maternal infection during pregnancy, and premature rupture of membranes ≥18 h had a good multivariate dependence on EONBI (P < 0.05), while there was no significant association with unexplained asphyxia, diabetic mother and child, and maternal fever at delivery (P > 0.05). The incidence of neonatal temperature >37.9°C was higher in the study group than in the reference group (P < 0.05), and there were no statistical differences in the comparison of other clinical manifestations (P > 0.05). The CRP level of neonates in the study group (47.33 ± 4.14) mg/L was higher than that of the reference group (4.84 ± 1.03) mg/L (P < 0.001). The WBC level of neonates in the study group (5.64 ± 1.18) 109/L was higher than that of the reference group (0.28 ± 0.04) 109/L (P < 0.001). The PCT level of neonates in the study group (5.41 ± 0.85) µg/L was higher than that of the reference group (0.24 ± 0.07) µg/L (P < 0.001). Conclusion EONBI is closely associated with several obstetric high-risk factors, including preterm birth, fecal contamination of amniotic fluid, maternal infection during pregnancy, and premature rupture of membranes ≥18 h; EONBI has no specific symptoms and signs, but serum CRP, WBC, and PCT levels are significantly higher than those of newborns without co-infection with bacteria.

Procalcitonin is associated with postnatal respiratory condition severity in preterm neonate. Pediatr Pulmonol 2022; 57:1272-1281. [PMID: 35064781 DOI: 10.1002/ppul.25846] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Revised: 12/31/2021] [Accepted: 01/20/2022] [Indexed: 11/06/2022]
Abstract
INTRODUCTION Postnatal respiratory failure is common in preterm neonates and is difficult to distinguish from early-onset neonatal bacterial infection by clinical symptoms. Similar to C-reactive protein (CRP), procalcitonin (PCT) is used as a marker of bacterial infection. Recently, it has been reported that the serum PCT levels increase because of respiratory failure immediately after birth. However, there is insufficient information concerning the relationship between biological inflammation markers, such as PCT and CRP, and postnatal respiratory condition severity. METHODS Preterm neonates were classified according to the received respiratory management as follows: nonrespiratory support (NRS), respiratory support (RS), surfactant administration therapy (STA), and STA with nitric oxide inhalation therapy (NO). The median serum PCT and CRP levels at 12-36 h postnatally were compared among the four groups. Additionally, the median serum PCT and CRP levels in the STA group were compared by STA timing and STA number. RESULTS The PCT levels for the NRS, RS, STA, and NO groups were 1.04, 6.46, 12.93, and 86.79 μg/L, respectively; the CRP levels were 0.40, 0.80, 1.10, and 16.40 mg/L, respectively. The PCT levels were significantly lower among neonates receiving STA in the birth subgroup (4.82 μg/L) than among those receiving STA in the admission subgroup (14.71 μg/L). The PCT levels were significantly higher among the STA multiple-dose subgroup (24.87 μg/L) than among the STA single-dose subgroup (12.47 μg/L). No significant differences in the CRP levels were observed. CONCLUSION The serum PCT levels in preterm neonates were associated with postnatal respiratory condition severity.

Abstract
BACKGROUND The early detection and prediction of bacteremic sepsis in preterm and term neonates remains a challenging task because of their nonspecific clinical presentations. We aimed to investigate the risk factors associated with bacteremia and find the cutoff values of predictive markers to achieve accurate diagnosis of neonatal bacteremic sepsis. METHODS Not-doing-well preterm and term neonates with suspected sepsis were retrospectively enrolled between January 2015 and December 2017 in Taipei Veterans General Hospital. Blood culture, hemogram, serum procalcitonin (PCT), and C-reactive protein (CRP) were drawn at the onset of clinical signs and symptoms. All cases were divided to either early-onset or late-onset groups according to postpartum age. Nonparametric statistic, logistic regression, and receiver operating characteristic analysis were performed to evaluate the risk factors and cutoff values for predicting bacteremia. RESULTS A total of 169 suspected sepsis episodes were analyzed, 68.0% of which had cardiopulmonary dysfunction and 19.5% had perinatal stress. The early-onset group had 123 (72.8%) patients, 4 of which had bacteremia and 119 had nonbacteremia conditions. The late-onset group had 46 (27.2%) patients, 8 of which had bacteremia and 38 had nonbacteremia conditions. Gestational age, birth body weight, Apgar score at 5 minutes, serum PCT, CRP, and platelet (PLT) count in the early-onset group and white blood cell (WBC) count in the late-onset group were substantially different between the patients with bacteremia and nonbacteremia conditions. PCT greater than 27 µg/L (adjusted odd ratio [aOR], 21.6; 95% CI, 1.1-435.1) and thrombocytopenia less than 100 × 109/L (aOR, 38.6; 95% CI, 1.4-1030.3) were predictive markers for bacteremia in the early-onset group. CONCLUSION Early- and late-onset neonatal sepsis had different risk factors and predictive markers of bacteremia. PCT and PLT count in the early-onset group and WBC count in the late-onset group were accurate diagnostic serum markers for neonatal bacteremic sepsis.
