Epidemiological Characteristics

Introduction: An early and accurate diagnosis of early onset neonatal sepsis (EONS) and late onset neonatal sepsis (LONS) is essential to improve the outcome of this devastating conditions. Especially, preterm infants are at risk. Reliable biomarkers are rare, clinical decision-making depends on clinical appearance and multiple laboratory findings. Markers of NET formation and NET turnover might improve diagnostic precision. Aim of this study was to evaluate the diagnostic value of NETs in sepsis diagnosis in neonatal preterm infants. Methods: Plasma samples of neonatal preterm infants with suspected sepsis were collected. Blood samples were assayed for markers of NET formation and NET turnover: cfDNA, DNase1, nucleosome, NE, and H3Cit. All clinical findings, values of laboratory markers, and epidemiological characteristics were collected retrospectively. Two subpopulations were created to divide EONS from LONS. EMA sepsis criteria for neonatal sepsis were used to generate a sepsis group (EMA positive) and a control group (EMA negative). Results: A total of 31 preterm neonates with suspected sepsis were included. Out of these, nine patients met the criteria for sepsis according to EMA. Regarding early onset neonatal sepsis (3 EONS vs. 10 controls), cfDNA, DNase I, nucleosome, and CRP were elevated significantly. H3Cit and NE did not show any significant elevations. In the late onset sepsis collective (6 LONS vs. 12 controls), cfDNA, DNase I, and CRP differed significantly compared to control group.

In Reply.— The comments raised by Baley et al are well taken and bring up one of the most important variables in the role of granulocyte transfusion in neonatal sepsis. Most of the studies to date have involved small numbers of patients in single institutions. This has prevented us from accumulating a large enough population of patients to adequately assess the role of either buffy coat transfusions or leukapheresed transfusions in this clinical setting. My comments in the commentary suggested that, with only eight patients in a group of preterm infants with presumed sepsis and only five patients with presumed sepsis with birth weights greater than 1,500 g, the numbers are essentially too small to determine any statistical significance between the role of buffy coat transfusions or supportive care.

Late Onset Sepsis

Introduction: Neonatal sepsis is a clinical syndrome characterized by signs and symptoms of infection with or without accompanying bacteremia in the first month of life.  It is responsible for about 30-50% of the total neonatal deaths in developing countries.  Neonatal sepsis can be divided into two sub-types depending upon whether the onset of symptoms within the first 72 hours of life (Early Onset Neonatal Sepsis) or after 72 hours of life (Late Onset Neonatal Sepsis ).  Meningitis is an important complication of late onset neonatal sepsis. Method: This was hospital based prospective observational study conducted among the neonates admitted with diagnosis of late onset neonatal sepsis in Neonatal Intermediate Care Unit (NIMCU) and Neonatal Intensive Care Unit (NICU) of Kanti Children’s Hospital from July 2016 to June 2017. The objective of this study was to evaluate the importance of performing LP in neonates with LONS. Results: 16.8% neonates with late onset neonatal sepsis were found to have meningitis. Among the neonates with meningitis CRP was positive 57.2% and negative in 42.8 %.  Among the cases with abnormal CSF findings, blood culture was sterile in 85% cases and organism was isolated 15% cases. In 88.8% cases with positive blood culture, no meningitis was detected. Lumbar puncture was traumatic in 1 neonate (0.8%) in first attempt. Apart from this no other complication of performing lumbar puncture was noted. Conclusion: Lumbar puncture and CSF examination is mandatory in all cases with late-onset sepsis.

Abstract Objective To systematically review and meta-analyze the role of lactoferrin supplementation to prevent late-onset sepsis (LOS) in preterm infants. Study Design Database search include PubMed, Web of Science, and Cochrane central for randomized clinical trial (RCTs). The Cochrane Grading of Recommendations Assessment, Development, and Evaluation methodology was used for summarizing the results. Results Ten RCTs involving 3,679 infants were included. Lactoferrin supplementation with or without probiotics decreased all LOS (relative risk [RR]: 0.56; 95% confidence interval [CI]: 0.36–0.86; I 2 = 58%; 10 studies; 3,470 subjects; level of evidence [LOE]: low) significantly. Similarly, lactoferrin supplementation without probiotics decreased all LOS (RR: 0.43; 95% CI: 0.29–0.62; I 2 = 0%; 8 studies; 1,209 subjects; LOE: moderate) significantly. Lactoferrin supplementation did not significantly reduce necrotizing enterocolitis (RR: 0.62; 95% CI: 0.29–1.33; I 2 = 43%; 6 studies; 3,079 subjects; LOE: low), all-cause mortality (RR: 0.74; 95% CI: 0.36–1.53; I 2 = 53%; 8 studies; 3,395 subjects; LOE: very low), bronchopulmonary dysplasia (RR: 1; 95% CI: 0.90–1.13; I 2 = 0%; 4 studies; 2,570 subjects; LOE: moderate), and threshold retinopathy of prematurity eligible for surgical treatment (RR: 0.61; 95% CI: 0.25–1.51; I 2 = 74%; 2 studies; 2,481 subjects; LOE: very low). Conclusion Low to moderate quality evidence suggests that lactoferrin supplementation reduces LOS in preterm infants. Further research is needed to improve the certainty in the evidence.

Objective Endocan, a proteoglycan secreted by endothelial cells, plays a role in the pathogenesis of sepsis. Endocan is an effective diagnostic and prognostic biomarker of sepsis in adult patients. We evaluate the utility of endocan as a new biomarker in the recognition of late-onset neonatal sepsis (LOS) in preterm infants. Methods This study included preterm infants at gestational age ≤ 32 weeks diagnosed with LOS. Sepsis was diagnosed in the presence of three or more clinical findings plus significant elevation of C-reactive protein (CRP) or interleukin 6 (IL-6) levels. Blood samples were obtained to determine leukocyte count, CRP, IL-6, and endocan levels immediately after the sepsis diagnosis and on the 3rd and 7th day after diagnosis. Results A total of 102 preterm infants, 52 with LOS (21 proven, 31 suspected sepsis) and 50 controls, were included in the study. Mean leukocyte count, serum CRP, IL-6, and endocan levels were significantly higher in the LOS group compared with healthy controls (p < 0.001) at enrolment. Serial measurements showed no significant difference in CRP and IL-6 levels between the proven and suspected sepsis groups, while endocan levels were significantly higher at enrolment and on day 7 in the proven sepsis group (p = 0.003 and p = 0.01, respectively). The endocan levels of preterm infants who died were significantly higher at all time points (p < 0.001, p = 0.001, and p = 0.004, respectively). Conclusion Endocan is an effective, reliable, and promising new biomarker for detecting LOS in preterm infants.

Abstract Background. Neonatal sepsis contributes substantially to neonatal morbidity and mortality. Procalcitonin (PCT) is a recognized biomarker for the diagnosis of late-onset neonatal sepsis (LONS), however, little is known about the prognosis value of PCT in LONS. This study aims at assessing PCT value as a prognosis biomarker in preterm infants with LONS. Methods. Retrospective single center observational cohort. All premature infants (less than 32 weeks of gestational age) with LONS admitted in a tertiary neonatal intensive care unit.Discussion. Among the 59 preterm infants included in the analysis, 48 survived (81.4%, 48/59). Deceased patients had a significantly lower gestational age (p=0,025) and weight (p= 0,016) at the time of LONS diagnosis. Although PCT values were not different between both groups at the time of LONS diagnosis, it was more elevated during the first 24 hours in deceased patients (p=0,041). Accuracy of PCT for LONS prognosis ranged from 0.70 to 0.82 of area under the curve on reciever operating characteristics curves. Optimal PCT cut-off values at LONS diagnosis was 8,92 µg/L (Youden’s J index 0.53), 15.75 µg/L for PCT values during the first 24 hours (J index 0.56), and 6.74 µg/L between 24 and 48 hours after diagnosis (J index 0.54). The estimated survival probability at day 60 was above 95% for patient with a PCT value at sepsis diagnosis under 8,9 µg/L and less than 45% if higher (p<0.0001). Conclusion. A PCT value > 8.92 µg/L obtained at LONS diagnosis suspicion seems to be a good prognosis biomarker.
