Abstract
OBJECTIVE It is not yet known whether systemic inflammatory indices affect the development of respiratory distress syndrome (RDS) in premature infants. We aimed to evaluate the relationship between systemic inflammatory indices obtained on the first day of life and the development of RDS in premature infants. STUDY DESIGN Premature infants with gestational age of ≤32 weeks were included in the study. Six systemic inflammatory indices involving neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), and systemic inflammation response index (SIRI) were measured in the first 1 hour after birth and compared in premature infants with and without RDS. RESULTS A total of 931 premature infants, 579 infants in the RDS group and 352 infants in the non-RDS group, were included in the study. MLR, PLR, and SIRI values were similar between the groups (p > 0.05 for all parameters). NLR, PIV, and SII values in the RDS group were significantly higher than those in the non-RDS group (p = 0.005, p = 0.011, and p < 0.001, respectively). In the predictivity of RDS, the AUC value of SII was 0.842 and the cut-off value was ≥78.200. Multiple logistic analysis showed that a higher level of SII (≥78.2) was independently associated with RDS (odds ratio: 3.03, 95% confidence interval: 1.761-5.301). CONCLUSION Our results demonstrated that a higher SII level (≥78.2) may be a predictor for the development of RDS in premature infants with gestational age of ≤32 weeks. KEY POINTS · It is not yet known whether systemic inflammatory indices affect the development of RDS.. · Our results demonstrated high SII levels may be a predictor for the development of RDS.. · SII may provide an advantage as a low-cost, easy-to-detect, useful and powerful parameter in RDS..

Abstract
BACKGROUND Previously, not six systemic inflammatory indices were evaluated in the diagnosis of early onset sepsis (EOS) in very low birth weight (VLBW, <1500g) premature infants. OBJECTIVES We evaluated the effectiveness of systemic inflammatory indices in the diagnosis of EOS in VLBW infants. METHODS Premature infants with birth weight <1500 g were included in the study. Six systemic inflammatory indices including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), and systemic inflammation response index (SIRI) were compared in patients with EOS (treatment group) and without EOS (control group). RESULTS Of 917 infants enrolled, 204 infants were in the EOS group and 713 infants comprised the control group. NLR, MLR and SIRI values were significantly higher in the EOS group than in the control group (p < 0.001). The AUC value of SIRI for the predictivity of EOS was 0.803. CONCLUSIONS The SIRI can be used together with other parameters as both an easily accessible and the reliable systemic inflammatory indices in the diagnosis of EOS in VLBW preterm infants.

Abstract
OBJECTIVE In our study, we aimed to investigate whether systemic inflammatory indices could be an indicator of mortality in very low birth weight (<1,500 g) preterm infants. METHODS Very low birth weight preterm infants were included in our study, and patient data were recorded retrospectively. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammation index, pan-immune-inflammation value, and systemic inflammation response index were calculated and recorded. The survivors and infants who died were compared for systemic inflammatory indices. RESULTS A total of 1,243 very low birth weight infants were included in the study. Of the patients, 1,034 survived and 209 died. Neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, pan-immune-inflammation value, systemic immune-inflammation index, and systemic inflammation response index were found to be statistically significantly lower in the mortality group than those in the survivor group (p=0.039, p=0.001, p<0.001, p<0.001, p<0.001, and p=0.002, respectively). According to the receiver operating curve analysis, systemic immune-inflammation index with the highest area under the curve (0.844) was found to be the most effective systemic inflammatory indices in predicting mortality with a cutoff level of ≤28.87 (p=0.0001). Multiple regression analysis showed that a lower level of systemic immune-inflammation index (≤28.87) was independently associated with mortality (OR: 1.677, 95%CI 1.061-2.685, p=0.001). CONCLUSION We have shown that low systemic immune-inflammation index value in very low birth weight preterm infants may be a novel systemic inflammatory index that can be used to predict mortality.

Sex Differences in Patent Ductus Arteriosus Incidence and Response to Pharmacological Treatment in Preterm Infants: A Systematic Review, Meta-Analysis and Meta-Regression.

[PMID: 35887640 PMCID: PMC9321725 DOI: 10.3390/jpm12071143] [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: 06/16/2022] [Revised: 07/05/2022] [Accepted: 07/08/2022] [Indexed: 11/16/2022] Open
Abstract
A widely accepted concept in perinatal medicine is that boys are more susceptible than girls to complications of prematurity. However, whether this ‘male disadvantage of prematurity’ also involves persistent patent ductus arteriosus (PDA) has been scarcely investigated. Our aim was to conduct a systematic review and meta-analysis on studies addressing sex differences in the risk of developing PDA among preterm infants. We also investigated whether the response to pharmacological treatment of PDA differs between boys and girls. PubMed/Medline and Embase databases were searched. The random-effects male/female risk ratio (RR) and 95% confidence interval (CI) were calculated. We included 146 studies (357,781 infants). Meta-analysis could not demonstrate sex differences in risk of developing any PDA (37 studies, RR 1.03, 95% CI 0.97 to 1.08), hemodynamically significant PDA (81 studies, RR 1.00, 95% CI 0.97 to 1.02), or in the rate of response to pharmacological treatment (45 studies, RR 1.01, 95% CI 0.98 to 1.04). Subgroup analysis and meta-regression showed that the absence of sex differences was maintained over the years and in different geographic settings. In conclusion, both the incidence of PDA in preterm infants and the response rate to pharmacological treatment of PDA are not different between preterm boys and girls.

The relationship between platelet indices and patent ductus arteriosus in preterm infants: a systematic review and meta-analysis. Eur J Pediatr 2021; 180:699-708. [PMID: 32949292 DOI: 10.1007/s00431-020-03802-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 08/12/2020] [Accepted: 09/04/2020] [Indexed: 01/11/2023]
Abstract
Patent ductus arteriosus (PDA), one of the most common disorders in newborns, is associated with many complications in premature infants such as respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD). However, the diagnosis of hemodynamically significant patent ductus arteriosus (hsPDA) is still an ongoing debate. The relationship between platelet parameters and hsPDA has been explored in many studies over the last decade, but there is still no definite conclusion. We aim to explain the relationship between platelet parameters and hsPDA through this meta-analysis. Therefore, we used PubMed, Embase, the Cochrane Library, and Web of Science databases as well as the Google Scholar to search for studies up to May 2020. Three reviewers independently screened the articles, evaluated the quality of the articles, and collected the data. The random-effects model and fixed-effects model were used to evaluate pooled results. We used the I-square (I2) test to examine heterogeneity and the funnel plot; Egger's test and meta-regression analysis were used to test for publication bias. Influence analysis was also carried out in this study. Stata version 12.0 software was used for data analysis. Fourteen studies, which included 3330 newborns, were extracted from 986 studies. The weighted mean difference (WMD) of the platelet count was - 17.98 (p < 0.001), the platelet distribution width (PDW) was 0.27 (p = 0.266), the mean platelet volume (MPV) was 0.01 (p = 0.958), the plateletcrit (PCT) was - 0.03 (p < 0.001), and the platelet mass was - 150.10 (p = 0.001).Conclusion: Platelet count, PCT, and platelet mass of the first 3 days of life are potentially helpful in identifying premature infants at risk of hsPDA. More prospective studies on the relationship between different degrees of thrombocytopenia and platelet function and hsPDA should be conducted. What is Known: • Platelets are involved in the formation of thrombi during closure of the arterial duct. • The diagnosis of hsPDA by Doppler echocardiography and clinical signs is not precise enough. What is New: • Preterm newborns with hsPDA in the first week of life demonstrated a significant reduction in platelet count, platelet mass, and plateletcrit in the first 3 days of life. • No significant difference was shown between hsPDA and non-hsPDA infants in platelet distribution width and mean platelet volume in the first 3 days of life.

Abstract
Platelets are critically involved in murine patent ductus arteriosus (PDA) closure. To date, the clinical significance of these findings in human preterm infants with PDA is still controversial. We discuss the available study data on the role of platelets for PDA closure in preterm infants: Several mostly retrospective studies have yielded conflicting results on whether thrombocytopenia contributes to failed spontaneous ductal closure. The same applies to investigations on the role of thrombocytopenia as a risk factor for unsuccessful ductus arteriosus closure by pharmacological treatment with cyclooxygenase inhibitors. Nonetheless, recent meta-analyses have concluded that thrombocytopenia constitutes an independent risk factor for both failed spontaneous and pharmacological PDA closure in preterm infants. However, the available investigations differ in regard to patient characteristics, diagnostic strategies, and treatment protocols. Several studies suggest that impaired platelet function rather than platelet number is critically involved in failure of ductus arteriosus closure in the preterm infant. A recent randomized-controlled trial on platelet transfusions in preterm infants with PDA failed to show any benefit for liberal vs. restrictive transfusion thresholds on PDA closure rates. Importantly, liberal transfusions were associated with an increased rate of intraventricular hemorrhage, and thus should be avoided. In conclusion, the available evidence suggests that thrombocytopenia and platelet dysfunction contribute to failure of spontaneous and pharmacological PDA closure in preterm infants. However, these platelet effects on PDA seem to be of only moderate clinical significance. Furthermore, platelet transfusions in thrombocytopenic preterm infants in order to facilitate PDA closure appear to cause more harm than good.

Platelet Counts and Patent Ductus Arteriosus in Preterm Infants: An Updated Systematic Review and Meta-Analysis. Front Pediatr 2021; 8:613766.

Abstract
Background: A meta-analysis published in 2015 showed a significant association between low platelet counts in the first day(s) of life and risk of patent ductus arteriosus (PDA). The meta-analysis pooled data from 11 studies cohorts (3,479 preterm infants). Objective: To update the meta-analysis by adding new studies on the topic and including other platelet parameters different from platelet counts. Methods: PubMed/Medline and Embase databases were searched. Random-effects risk ratios (RR) and differences in means (DM) and 95% confidence intervals (CI) were calculated. Results: We included 31 studies (7,638 infants). Meta-analysis showed that the risk of developing any PDA was significantly associated with platelet counts<150 × 109/L (11 studies, RR 1.58, 95% CI 1.28 to 1.95), and <100 x 109/L (7 studies, RR 1.61, 95% CI 1.14 to 2.28), but not <50 x 109/L (4 studies, RR 1.34, 95% CI 0.77 to 2.32). Risk of developing hemodynamically significant PDA (hsPDA) was significantly associated with platelet counts<150 x 109/L (12 studies, RR 1.33, 95% CI 1.09 to 1.63), and <100 x 109/L (7 studies, RR 1.39, 95% CI 1.06 to 1.82), but not <50 x 109/L (6 studies, RR 1.24, 95% CI 0.86 to 1.79). Infants with hsPDA had significantly lower mean platelet counts (19 studies, DM 22.0 x 109, 95% CI 14.9 to 29.1) and platelet mass (11 studies, DM 214.4, 95% CI 131.2 to 297.5) and significantly higher platelet distribution width (PDW, 9 studies, DM -0.53, 95% CI -1.01 to -0.05) than infants without hsPDA. Meta-analysis could not demonstrate significant differences in mean platelet volume (MPV). Conclusion: Compared to the previous analysis, this updated meta-analysis included 21 additional studies that provide stronger evidence of the association between low platelet counts and PDA/hsPDA. Other platelet parameters such as platelet mass and PDW are also associated with hsPDA risk. However, the low number of platelets may be an epiphenomenon associated with the maturity and clinical stability of preterm infants rather than a contributing factor in the pathogenesis of PDA.

Abstract
Background Sepsis is a life-threatening and inflammatory disease with high morbidity and mortality. Red blood cell distribution width to platelet count ratio (RPR) was known as an inflammatory biomarker and was related to poor outcomes of various diseases. Aim This study was intended to explore the association between RPR and mortality of sepsis patients. Methods A retrospective cohort study was undertaken in patients with sepsis, and the data were collected from a public database called Medical Information Mart for Intensive Care III (MIMIC-III). The primary outcome was 28-day mortality while the secondary outcomes were 90-day mortality and ICU mortality. Multivariable regression analyses, as well as interaction and stratified analyses, were conducted to investigate the relation between RPR and sepsis mortality. Results In total, we enrolled 7531 patients with 1316 deaths. RPR was independently correlated with 28-day mortality (per 0.1 increase: HR=1.04; 95% CI 1.02–1.06), 90-day mortality (per 0.1 increase: HR=1.04; 95% CI 1.03–1.06) and ICU mortality (per 0.1 increase: OR=1.06; 95% CI 1.02–1.10). Twenty-eight-day survival was worse in the high RPR (≥0.134) group according to the Kaplan–Meier curve analyses (Log rank test, p<0.001). In stratified analyses, Sequential Organ Failure Assessment (SOFA) score and length of ICU stay had interactive effects with the high RPR (≥0.134) group on 28-day mortality. Conclusion RPR is a novel biomarker that indicates poor prognosis of sepsis patients. Clinicians are required to pay more attention to those patients with high RPR.

Abstract
Introduction: In premature neonates, the persistence of hemodynamically significant ductus arteriosus (hsPDA) can be associated with short- and long-term consequences, impairing their outcome. The correct strategy of management for such condition is under debate, especially regarding contraindications and/or side effects. In recent years, metabolomics was applied to several perinatal, pediatric, and adult conditions to investigate potential biomarkers of disease, which have become useful for early diagnosis and/or therapeutic management. Aim of the Study: The main purpose of our exploratory study was to asses, through 1H-NMR metabolomics analysis of urinary samples at birth, possible metabolic pathways differentiating, with a significant predictive power, those preterm neonates who will subsequently develop hsPDA and neonates of comparable gestational age (GA) who will undergo spontaneous ductal closure or the persistence of an irrelevant PDA (no-hsPDA). Moreover, we investigated potential prenatal or perinatal clinical factors potentially influencing the development of hsPDA. Materials and Methods: We enrolled n = 35 preterm neonates with GA between 24 and 32 weeks; urinary samples were collected within the first 12 h of life. Patients were closely monitored regarding intensive care, respiratory support, fluid balance and administered drugs; an echocardiogram was performed at 48-72 h. Results: Our results reported a significant correlation between lower GA at birth and the development of hsPDA. Moreover, neonates with GA ≤ 30w developing hsPDA were characterized by lower Apgar scores at 1' and 5', higher rates of perinatal asphyxia, higher need of delivery room resuscitation and subsequent surfactant administration. Interestingly, metabolomics analysis at birth detected a clear separation between the 1H-NMR urinary spectra of subjects GA ≤ 30w not developing hsPDA (n = 19) and those of subjects born at GA ≤ 30w in which hsPDA was confirmed at 48-72 h of life (n = 5). Conclusions: This is the first study applying metabolomics to investigate the PDA condition. Although preliminary and conducted on a limited sample, our results reveal that metabolomics could be a promising tool in the early identification of hsPDA, potentially superior to the clinical or laboratory predictive tools explored to date and even to the clinical observations and correlations in our sample, through the detection of specific urinary metabolites.
