Copeptin as an inflammatory marker in diagnosis and prognosis of neonatal sepsis

BackgroundCopeptin is an immediate biomarker of individual stress response; many life-threatening diseases are causing a high elevation of its concentration in plasma, such as myocardial infarction and cardiovascular shock. Moreover, copeptin is a promising marker in sepsis. We aimed to evaluate copeptin as a diagnostic and prognostic marker in neonatal sepsis for the early initiation of appropriate therapy and the prediction of mortality. A prospective case-control study involved 237 neonates (165 cases had neonatal sepsis, and 72 served as controls). Cases were admitted to the neonatal intensive care unit (NICU) and followed up for symptoms and signs of sepsis confirmed by laboratory data: complete blood count (CBC), c-reactive protein (CRP), and cultures. Serum copeptin level by the enzyme-linked immunosorbent assay (ELISA) was measured for all included neonates. We observed that the copeptin level was significantly higher in cases than control (3.51 ± 1.4, 1.61 ± 0.51 pmol/liter, respectively). The cut-off value of copeptin at which we can discriminate between cases and controls was above 2.065 pmol/liter. Among cases, copeptin was higher in early-onset sepsis (EOS) than late-onset sepsis (LOS) neonates, and there was a significant correlation between its level and all the following: age at admission, birth weight, gestational age, history of perinatal asphyxia, maternal chorioamnionitis, and premature rupture of membrane (PROM). Also, copeptin was strongly associated with CRP level and the poor prognosis of patients. Copeptin can predict the death of cases at a cut-off value above 2.995 pmol/liter.ConclusionSerum copeptin level can be used as a diagnostic and prognostic marker in neonatal sepsis.

Role of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in diagnosing neonatal sepsis.

Clinical manifestations of neonatal sepsis are often unspecified. Therefore, sepsis biomarkers could be used to support diagnosis while waiting for blood culture results, such as the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). The aim of this study was to evaluate the role of NLR and PLR as diagnostic markers in neonatal sepsis. A cross-sectional study was conducted at Haji Adam Malik General Hospital, Medan, Indonesia, from April to October 2019. This study included neonates aged less than 28 days, diagnosed with suspected sepsis, and had no previous history of antibiotics administration. Patients underwent clinical assessment, laboratory examination, and blood culture. Patients were grouped into sepsis and non-sepsis based on the blood culture results. The median hematological examination and the range of NLR and PLR in both the sepsis and non-sepsis groups were subjected to analysis using the Mann-Whitney U test to assess differences. NLR and PLR optimal cut-off values were determined using a receiver operator curve (ROC) with a confidence interval of 95%. A total of 137 neonates were enrolled, of which 49 were classified as sepsis and 89 as non-sepsis based on blood culture results. The optimal cutoff values for NLR and PLR were 2.75 and 11.73. Using those cutoff values, NLR and PLR could predict neonatal sepsis with sensitivities of 52.1% and 47.9%, specificities of 50.6% and 47.2%, area under the curve (AUC) of 0.46 and 0.47, with p=0.525 and p=0.662, respectively. Further investigation is warranted to refine the NLR and PLR utility and enhance diagnostic accuracy in clinical practices.

The Diagnostic and Prognostic Values of Soluble CD14 Subtype (Presepsin) in Early Detection of Early Onset Neonatal Sepsis in Preterm Newborns

Abstract Background The diagnosis of “suspected sepsis” in neonates in the NICU is one of the most common and challenging diagnoses due to the nonspecific signs of sepsis. therefore, laboratory investigation is necessary in cases of doubt or if there are risk factors. A promising biomarker: Presepsin (P-SEP), or Soluble Cluster of Differentiation 14 Subtype (sCD14-ST) is generated as a part of the body’s response to bacterial infection. It is effective in the early phase of inflammation, and it is detected as an early marker of sepsis in neonates. Aim and Objectives to evaluate the diagnostic value of presepsin in early neonatal sepsis and prognostic value for severity, mortality and hospital stay length. Subjects and Methods This prospective observational study include two groups, one group included 36 neonates with risk factors for early-onset sepsis, along with 20 uninfected neonates as the control group. Both groups were subjected to the calculation of Rodwell score, SNAP II score, serum presepsin levels, CRP measurement, and blood culture and assessed for clinical severity, mortality, and hospital stay length. Result Serum baseline presepsin was significantly elevated in sepsis group (P < 0.001), Presepsin showed the best diagnostic performance over Rodwell score (AUC 0.989; sensitivity of 93.8% and specificity of 95%). Presepsin levels on day 3 were significantly elevated in non-survived patients (P < 0.001), with better predictive performance for 28-day mortality and rapid progression to death than SNAP II score (AUC 0.880; sensitivity of 83.3% and specificity of 87.5%). Conclusion presepsin day 1 was useful diagnostic tools in culture proven early onset neonatal sepsis, presepsin at day 3 could be a good predictor for gram negative infections, 28-day mortality, and sepsis severity.

Prognostic Value of Pentraxin 3 and Procalcitonin in Late onset Neonatal Sepsis

Abstract Background Sepsis is a major cause of intensive care unit (ICU) admission. Procalcitonin (PCT) could be an important prognostic marker for sepsis. Pentraxin 3 (PTX3) and PCT are detectable in patients with sepsis within a large time window after the onset of sepsis. Objective To assess the prognostic value of the PTX3, PCT in neonatal sepsis in comparison with other sepsis screen. Patients and Methods A prospective study included 40 neonates with sepsis. The study had been conducted in the neonatal intensive care units of Ain Shams University, Children’s Hospital during the period from January 2020 to May 2022. All neonates had been subjected to clinical examination, anthropometric measurements and sepsis scoring by neonatal sequential organ failure assessment (nSOFA). Laboratory investigations were collected from all pediatrics including Complete blood count (CBC), quantitative C- reactive protein (CRP), blood culture, serum pentraxin 3 (PTX3) and serum procalcitonin (PCT). Sepsis markers had been obtained from neonates at the day of being with suspected sepsis before starting the antimicrobial therapy (Day 0). While blood samples for sepsis markers reobtained only from neonates with positive blood cultures on the 3rd (Day3), accordingly our patients divided into improved and deteriorated groups. Results There was a significant decrease in CRP level and increase in procalcitonin and pentraxin 3 levels in deteriorated group than improved group at baseline with p-value = 0.004, 0.016 and 0.019; respectively. Also, the study shows that there was a significant increase in CRP, procalcitonin and pentraxin 3 levels in deteriorated group than improved group after 3 days with p-value = 0.002, <0.001 and <0.001; respectively. Furthermore, in improved group, there was a significant decrease in the level of CRP, procalcitonin and pentraxin 3 after 3 days than at baseline with p-value = 0.001, <0.001 and 0.001; respectively. Also in deteriorated group, there was statistically significant increase in the CRP and pentraxin 3 levels after 3 days than at baseline in deteriorated group with p- value = 0.002 and 0.019; respectively while no change found in procalcitonin level. Conclusion Serum pentraxin 3 and procalcitonin levels seem to be promising prognostic markers in neonatal sepsis with higher sensitivity and specificity for procalcitonin than pentraxin at 3 days.

Serum calprotectin as a marker of neonatal sepsis: a hospital-based cross-sectional diagnostic study

Background Despite significant advances in neonatal care, neonatal sepsis remains a major contributor to mortality, morbidity, and protracted hospitalization. The development of early possible diagnostic indicators for newborn sepsis is critical. Since calprotectin participates in major biological processes, it could be a diagnostic marker for infection/inflammation. This study aimed to estimate serum calprotectin in neonates with clinical sepsis. In addition, we compared serum calprotectin with standard sepsis markers and serum procalcitonin to evaluate its diagnostic accuracy. Methods A hospital-based cross-sectional diagnostic study of neonates identified with clinical sepsis using standard criteria was carried out. We compared estimated serum calprotectin levels to serum procalcitonin levels and conventional sepsis markers (leucocyte count, blood culture, immature to total neutrophil ratio, and C- reactive protein). We used SPSS version 25 to analyze the data. To examine diagnostic accuracy and determine a cut-off value for serum calprotectin, we used the receiver operating characteristics (ROC) curve. Results Of the 83 subjects included, 36.5% (30/83) had blood culture positive status, the median value of serum calprotectin being 0.93 ng/ml (0.67 to 1.3). Respiratory, cardiovascular, and gastrointestinal instabilities were present in 67.5% (56/83), 59% (49/83), and 50.1% (42/83) cases, respectively. The median values of serum calprotectin, procalcitonin, TLC, and I/T ratio between neonates withpositive blood culturesand negative culturesdid not differ significantly.. On ROC, calprotectin was not predictive for blood culture positivity (sensitivity: 50%; specificity: 44% at 0.83 ng/ml of serum calprotectin) and C-reactive protein (CRP) levels (sensitivity: 57%; specificity: 67% at serum calprotectin levels of 0.89 ng/ml). However, compared with serum procalcitonin, serum calprotectin at 1.2 ng/ml had sensitivity and specificity of 60% and 73%, respectively. Conclusions Serum calprotectin did not show a distinct advantage over the existing sepsis markers. Serum calprotectin level at 1.2 ng/ml had a sensitivity and specificity of 60% and 73%, respectively, compared to serum procalcitonin in detecting neonatal sepsis.

The combination of neutrophil to lymphocyte ratio and platelet to lymphocyte ratio improves accuracy of neonatal sepsis diagnosis

Background Neonatal sepsis remains a challenging issue, due to sophisticated and time consuming tests needed to confirm a diagnosis.
 Objective To assess the applicability of neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) as diagnostic markers in neonatal sepsis.
 Methods This cross-sectional study was conducted in the Neonatology Ward of Kandou General Hospital, Manado, North Sulawesi. Neonates with suspected sepsis were included by consecutive sampling. We measured NLR and PLR form hematology profiles and differential count. Diagnosis of neonatal sepsis was based on positive blood cultures. A receiver operating characteristic (ROC) curve analysis was done to assess the NLR and PLR cut-off points. Chi-square test was used to analyze the diagnostic value of NLR and PLR.
 Results A total of 176 full term neonates with suspected sepsis were included in the study. Of these, 84 (47.7%) subjects were confirmed with neonatal sepsis and 92 (52.3%) were non-sepsis. The mean NLRs were 5.9 (95%CI 2.0 to 13.6) in the sepsis group and 1.6 (95%CI 0.2 to 3.2) in the non-sepsis group. A NLR of 3.0 was determined as the predictive cut-off value of neonatal sepsis (sensitivity 94%, speci?city 97.8%, and area under the ROC curve 0.995). NLR can effects on neonatal sepsis diagnosis by 61% . The mean PLRs were 79.9 (95%CI 44.0 to 155.8) in the sepsis group and 44.0 (95%CI 9.7 to 91.8) in the non-sepsis group. A PLR of 60.4 was determined as the predictive cut-off value of neonatal sepsis (sensitivity 86.9%, speci?city 87%, area under ROC curve 0.928). PLR can effects on neonatal sepsis diagnosis by 47.5%. When NLR and PLR were combined, they can improve accuracy of neonatal sepsis diagnosis about 72.2%.
 Conclusion Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) can be used in combination as adjunct diagnostic tests for neonatal sepsis workups.

Diagnostic accuracy of procalcitonin as a marker of neonatal sepsis

Background: Sepsis is defined as “life-threatening organ dysfunction, caused by a dysregulated host response to infection”. Neonatal sepsis is the most common cause of morbidity and mortality in the neonatal period. Early diagnosis of neonatal sepsis is difficult. Therefore, this study was conducted with the objective to assess the diagnostic accuracy of procalcitonin as marker of neonatal sepsis and its comparison with C-reactive protein. Methods: The present study was a hospital-based descriptive comparative study. A total of 59 neonates were enrolled. All suspected neonates for the sepsis admitted to NICU were enrolled in study on the basis of inclusion and exclusion criteria. A detailed clinical examination was done. Blood sample was collected for procalcitonin, C-reactive protein and blood culture. Statistical analysis was performed. Results: In our study diagnostic accuracy of procalcitonin in diagnosis of neonatal sepsis was sensitivity (88.46%), specificity (87.88%), positive predictive value (85.19%), negative predictive value (90.63%) and diagnostic accuracy (88.14%). Diagnostic value of C-reactive protein in diagnosis of neonatal sepsis was sensitivity (88.46%), specificity (69.70%), positive predictive value (69.70%), negative predictive value (88.46%) and diagnostic accuracy (77.97%). Diagnostic accuracy of procalcitonin is maximum followed by C-reactive protein. Conclusions: In our study all patient with gram negative organism were procalcitonin positive whereas 50% Staphylococcus aureus were procalcitonin positive and in candida positive cases out of 6 cases, 5 (83.3%) were procalcitonin positive.

Combination of red cell distribution width and procalcitonin as diagnostic biomarkers of neonatal sepsis in preterm infants

Background Diagnosis of neonatal sepsis is still challenging. Several diagnostics test have been developed to help diagnose of neonatal sepsis, but sometimes it could not be done routinely in limited facilities. Procalcitonin (PCT) and red cell distribution width (RDW) have been reported to have correlations with the risk of developing sepsis.
 Objective To evaluate the diagnostic value of combined of PCT and RDW as markers for neonatal sepsis in preterm infants.
 Methods A cross sectional study was conducted in the neonatal ward, Syaiful Anwar hospital, Malang, East Java. The subjects were preterm infants with neonatal sepsis. Blood culture were taken as the gold standard and RDW and PCT levels were assessed as the comparison. All of the test were performed at the begining of the study. The incidence of sepsis was reported as the main outcome. The data obtained were processed and analyzed using the receiver operating characteristic (ROC) method to obtain the area under curve (AUC) value.
 Results Fifty-five preterm infants presenting neonatal sepsis were enrolled in this study. The combination of RDW and PCT showed AUC 0.814 (P=0.199) with sensitivity and specificity 78.9% and 80.6%, respectively in diagnosing neonatal sepsis compared to blood culture.
 Conclusion Combination of RDW and PCT as markers of sepsis in preterm infants have good sensitivity and specificity.

The Role of Salivary C-Reactive Protein in Diagnosis of Neonatal Sepsis

Background Neonatal sepsis remains one of the leading causes of morbidity and mortality among neonates. Objective to evaluate the role of salivary C-reactive protein (CRP) as a diagnostic marker in neonatal sepsis. Methods This case-control study was carried out on 90 neonates including 45 neonates with symptoms and signs suggestive of neonatal sepsis and 45 healthy neonates as controls. All neonates were subjected to full history taking, thorough clinical examination, laboratory investigations including complete blood count (CBC), serum CRP, blood culture, and salivary CRP. Results Septic neonates showed significantly higher salivary CRP compared to controls; it was significantly associated with positive serum CRP, blood culture, and hematological scoring system (HSS). It was significantly higher in neonates who died compared to those who survived. Twenty one cases with positive salivary CRP showed significant positive correlations with the length of the neonatal intensive care unit stay, total white blood cell (WBC) count, mean platelet volume (MPV), neutrophils to lymphocytes ratio (NLR), serum CRP, HSS, significant negative correlations with gestational age, birth weight, APGAR at 1, 5 min, and platelet count. Receiver operating characteristic (ROC) curve for salivary CRP showed that at cut-off value of 0.135 mg/L, the sensitivity was (81.8%) and the specificity was (75.6%) for detecting neonatal sepsis. Conclusion Salivary CRP was significantly higher in the septic group, and was associated with positive serum CRP. Hence, salivary CRP could be considered a novel non-invasive biomarker for diagnosing neonatal sepsis.

Role of Red Cell Distribution Width as a Prognostic Marker in Neonatal Sepsis

Objective: To determine the prognostic value of red cell distribution width (RDW-CV%) in predicting the outcome in neonatal sepsis.Methodology: It was an observational study conducted at the Pakistan Institute of Medical Sciences, Islamabad, from December 2018 to April 2020. A total of 136 neonates at term with clinical suspicion of neonatal sepsis were equally divided based on RDW into two groups as normal and raised RDW. A complete blood count and C-reactive protein were done on the day of admission and repeated on Day 3. Outcomes were observed in terms of discharges, expiries and length of hospital stay.Results: The mean RDW of Group 1 (normal RDW) was 14.71±0.65 on Day 1 and 17.14±0.14 on Day 3 with a significant p-value of <0.001. In group 2 (Raised RDW) on Day 1 it was 17.14±1.46 and at day-3 was 17.8±1.90 with a p<0.001. Discharged neonates in group 1 were 57 (83.8%) and in group 2 were 46 (67.6%). (p=0.458). Expired neonates in Group-1 were 11(16.2%) and in group-2 were 22(32.4%) with significant p-value of 0.028. Neonates shifted to ventilator in group-1 were 10 (14.7%) and in group-2 were 24(35.3%) with p-value (0.006). Length of hospital stay in terms of days in group1 with mean 5.85± 4.03 and group-2 it was 7.63± 4.82 with a significant p-value of <0.001.Conclusion: Raised RDW in clinically septic neonates was associated with poor outcomes in terms of length of hospital stay, mechanical ventilation and deaths compared to neonates with normal RDW.Keywords: Red cell distribution width, Sepsis, Neonatal

Neutrophil to lymphocyte ratio as a marker of neonatal sepsis in resource limited settings

Background: Neonatal period forms basic foundation which influences the future health of a child. It is often complicated by neonatal sepsis. In resource limited settings especially in rural and tribal areas with limited laboratory services it will be not possible to have all investigations. Study aims to determine utility of simple neutrophil to lymphocyte ratio as a marker of sepsis in neonates within the first week of life.Methods: Retrospective descriptive study in a tertiary care hospital in Kochi. Objective of this study was to analyse neutrophil to lymphocyte ratio in babies with sepsis to that of babies without sepsis. Data of 300 babies were collected which included 150 babies with sepsis and 150 babies with no sepsis. Records showing complete history, clinical diagnosis, appropriate investigation and management details of term babies within 7 days of life were included. Preterm babies, Babies with congenital malformations, outborn babies, babies with incomplete records were excluded.Results: In this study, mean value of neutrophil to lymphocyte ratio in babies with sepsis were 3.73 compared to 1.22 in babies with no sepsis. For babies with sepsis±1SD values were 5.21 and 2.25 respectively and for babies with no sepsis were 1.74 and 0.70. For babies with sepsis±2 SD values 0.77 and 6.69 respectively and 0.18 and 2.26 for babies with no sepsis.Conclusions: Mean values of NLR values were significantly higher in those with sepsis than in those without sepsis NLR ratio is higher in cases with sepsis (3.728±1.483) compared to the cases with no sepsis (1.217±0.521). A value more than 2.25 can be indicator of sepsis.

НЕОНАТАЛЬНЫЙ СЕПСИС: СОВРЕМЕННЫЕ ДИАГНОСТИЧЕСКИЕ ВОЗМОЖНОСТИ

The literature review presents current knowledge of risk factors, etiology, the main links of immunopathogenesis, clinical manifestations and laboratory guidelines for neonatal sepsis (NS). It is emphasized that NS remains a serious health problem. At the same time, it is specified that the incidence rates of early HS in children born prematurely are 60 times higher than in fullterm children, and mortality is 16.6 times higher. It was also noted that the frequency of late NS with an increase in body weight at birth from 500 g to 2500 g decreases from 51.2% to 2.2%. The main predisposing factors of increased morbidity and mortality from NS in premature infants are presented. The modern possibilities of laboratory diagnostics of the disease are analyzed in detail. The main characteristics (sensitivity, specificity, diagnostic significance) of clinical and laboratory markers of NS are given. It is emphasized that the diagnosis of NS remains clinical, which does not exclude the important task of finding highly sensitive and highly specific markers for more accurate and early screening of this disease, which will allow timely initiation of adequate therapy and ultimately determine a decrease in mortality and long-term consequences for health and quality of life.

Study of Diagnostic Value of D-Dimer Serum Level as a Marker in Neonatal Sepsis

Influence of Pathogen Type on Neonatal Sepsis Biomarkers.

Understanding immunoregulation in newborns can help to determine the pathophysiology of neonatal sepsis and will contribute to improve the diagnosis, prognosis, and treatment and remains an urgent and unmet medical need to understand hyperinflammation or hypoinflammation associated with sepsis in newborns. This study included infants (up to 4 days old). The “sepsis” criteria was a positive blood culture. C-reactive protein demonstrates a strong dependence on the pathogen etiology. Therefore, its diagnostic odds ratio in Gram-positive bacteremia was 2.7 and the sensitivity was 45%, while Gram-negative was 15.0 and 81.8%, respectively. A neutrophil-lymphocyte ratio above 1 and thrombocytopenia below 50∗109 cells/L generally do not depend on the type of pathogen and have a specificity of 95%; however, the sensitivity of these markers is low. nCD64 demonstrated good analytical performance and was equally discriminated in both Gram (+) and Gram (−) cultures. The sensitivity was 87.5–89%, and the specificity was 65%. The HLA-DR and programmed cell death protein study found that activation-deactivation processes in systemic infection is different at points of application depending on the type of pathogen: Gram-positive infections showed various ways of activation of monocytes (by reducing suppressive signals) and lymphocytes (an increase in activation signals), and Gram-negative pathogens were most commonly involved in suppressing monocytic activation. Thus, the difference in the bacteremia model can partially explain the problems with the high variability of immunologic markers in neonatal sepsis.

Study the role of c-reactive protein and thrombocytopenia in diagnosing early neonatal sepsis

Background: In clinical practice, early detection of neonatal sepsis remains difficult. Neonatal sepsis diagnosis is a challenge because of its non-specific presentation and the low sensitivity of the time-consuming bacterial cultures. So, many sepsis markers, like C-reactive protein (CRP) and platelet count, are emerging to improve its diagnosis. The aim of the study was to evaluate the role of CRP and platelet count in early neonatal sepsisMethods: This study was conducted in the department of SNCU in Virudhunagar Government Headquarters hospital, 50 neonates with culture-confirmed sepsis were included. Before antibiotic treatment, neonates CRP and platelet count, and other inflammatory markers were assessed.Results: In 50 newborns, culture was positive in 22 cases, CRP was positive in 24 cases, and thrombocytopenia in 18 cases. In 22 culture-positive cases, 19 cases are CRP positive, and 17 cases had thrombocytopenia. In 17 culture-positive thrombocytopenia cases, 16 cases are Gram-negative stain, 1 case is Gram-positive stain.Conclusions: CRP and Platelet can be helpful in the future diagnosis of neonatal sepsis, despite being promising and convenient markers for neonatal sepsis.
