A meta-analysis on first-trimester blood count parameters-is the neutrophil-to-lymphocyte ratio a potentially novel method for first-trimester preeclampsia screening? Front Med (Lausanne) 2024; 11:1336764. [PMID: 38633299 PMCID: PMC11021791 DOI: 10.3389/fmed.2024.1336764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Accepted: 03/11/2024] [Indexed: 04/19/2024] Open
Abstract
Objective Meta-analysis focusing on the role of first-trimester neutrophil-to-lymphocyte ratio (NLR) in the prediction of preeclampsia. Data sources PubMed, Scopus, Web of Science, Cochrane Library, and Embase databases were queried from inception up to December 31, 2022. Study eligibility criteria The study included all types of original research that was conducted in humans and values of NLR were measured during the first trimester, among patients who later developed preeclampsia, compared to the values of control groups. Study appraisal and synthesis methods Two reviewers independently performed data abstraction and quality appraisal, and disagreements were resolved by consensus and, if necessary, by the opinion of a third reviewer. During the analysis, PRISMA and MOOSE guidelines were followed. All statistical analyses were made with R. Results For the research on the predictive role of NLR values in the first trimester for preeclampsia, a total of 6 studies were selected for analysis, covering 2,469 patients. The meta-analysis revealed a 95% confidence interval (CI) for the effect size of 0.641 to 1.523, with a prediction interval of 0.027 to 2.137. Conclusion Based on the analysis, NLR is a promising biochemical marker for future pieces of research that try to find new screening methods for first-trimester preeclampsia. We encourage other researchers to examine NLR's predictive value combined with other markers in preeclampsia screening, this way being able to find new and affordable protocols for first-trimester preeclampsia screening. Systematic review registration identifier CRD42023392663.

Diagnostic value of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratio to predict recurrent pregnancy loss and abortion; a systematic review and meta-analysis. Immun Inflamm Dis 2024; 12:e1210. [PMID: 38506423 PMCID: PMC10953208 DOI: 10.1002/iid3.1210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 02/05/2024] [Accepted: 02/29/2024] [Indexed: 03/21/2024] Open
Abstract
OBJECTIVE This systematic review and meta-analysis aimed to evaluate the diagnostic value of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in women with a history of abortion (missed and threatened) and recurrent pregnancy loss (RPL) in comparison with healthy pregnancies. METHODS Electronic databases including MEDLINE, Scopus, Web of Science, Embase, and Cochrane Library were searched for NLR and PLR in women who experienced early pregnancy loss up to January 1, 2023 with a combination of proper keywords. Meta-analysis was done for comparison with three or more studies and summary estimates were measured. RESULTS A total of 390 citations were retrieved initially, and after screening, 16 articles were deemed eligible for the final review. Among these, 14 studies underwent meta-analysis. The meta-analysis revealed that the standard mean of the NLR was significantly higher in abortion cases compared to the control group. However, there was no significant difference in the PLR between the pregnancy loss group and the control group. CONCLUSION NLR was significantly higher among RPL patients compared to the control group, according to these data, NLR may be capable of being used in the diagnosis of RPL as an easy, cheap, and accessible modality. Further studies, which take these variables into account, will need to be undertaken to determine the diagnostic value of NLR and PLR in early pregnancy loss.

Abstract
The aim of this retrospective study was to demonstrate the effectiveness of APRI, DNI, NLR, PLR, and PDW in predicting the severity of gestational hypertension (GHT) and PE and to determine whether these factors can be used as screening tools. Normotensive pregnant women (n = 792) served as the control group. 1,213 single pregnant women who met the following criteria for a GHT diagnosis were included in the study group. We found a significantly higher mean PLR and NLR value. The mean PDW value was significantly lower in the control group than in the other groups. The SPE group had a significantly higher mean APRI score. The groups did not differ by their DNI. We determined PDW and APRI as independent parameters that predicted SPE by multiple logistic regression analysis. In retrospective analysis of blood samples taken from these participants below week 20, we found that the APRI value differed significantly between the control and SPE groups. NLR, PLR, DNI, and PDW had no clinical significance. We further suggested that APRI may provide a clinical indication of progression from hypertensive pregnancy disorders to SPE, which seems to be a promising implication that should be verified by further studies.IMPACT STATEMENTWhat is already known on this subject? Hypertensive disorders in pregnancy are a major cause of maternal and perinatal morbidity and mortality. Screening pregnant women for risk factors for developing hypertensive disorders and identifying women at high risk in early pregnancy and initiating prophylactic treatment are important for pregnancy monitoring and planning in experienced centres. Because only 30% of women who will develop preeclampsia can be predicted by risk factors, the combined use of laboratory tests and imaging with risk factors to calculate a woman's risk of developing preeclampsia is currently being investigated. However, no proven marker has yet been found.What do the results of this study add? In our study, we found that NLR, PLR, DNI, and PDW have no clinical significance in assessing the risk of developing gestational hypertension and preeclampsia and in predicting the severity of preeclampsia. However, in our study, we found that APRI can provide a clinical indication of the progression of hypertensive pregnancy to SPE.What are the implications of these findings for clinical practice and/or further research? This study represents an important contribution to the literature because it is the first study to examine the association between APRI and HT in pregnancy.

Abstract
OBJECTIVES This study aimed to clarify the relationship between white blood cell (WBC) and adverse pregnancy outcomes. DESIGN A total of 25 270 pregnant women underwent peripheral blood white blood cell count tests in the first, second and third trimesters. Adverse pregnancy outcomes were gestational hypertension, pre-eclampsia, gestational diabetes mellitus, preterm birth, low birth weight, caesarean delivery, macrosomia and fetal distress. Due to acute infectious disease or other diseases, 1127 were excluded. SETTING Minhang Hospital, China. PARTICIPANTS A total of 24 143 pregnant women were included in this study. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was the adverse pregnancy outcomes. RESULTS For the 24 143 participants, we calculated adjusted ORs for adverse pregnancy outcomes associated with an increased WBC count. For gestational hypertension, the ORs were 1.18 (95% CI, 1.05 to 1.24) in the first trimester and 1.10 (1.06 to 1.13) in the second trimester; for pre-eclampsia, ORs were 1.14 (95% CI, 1.47 to 1.64) in the first trimester and 1.10 (1.05 to 1.16) in the second trimester; for gestational diabetes mellitus, ORs were 1.06 (95% CI, 1.00 to 1.13) in the first trimester and 1.10 (1.04 to 1.16) in the second trimester; for preterm birth, ORs were 1.12 (95% CI, 1.06 to 1.18) in the first trimester, 1.10 (1.06 to 1.13) in the second trimester and 1.12 (1.09 to 1.15) in the third trimester; for low birth weight, ORs were 1.09 (95% CI, 1.02 to 1.17) in the first trimester, 1.03 (0.99 to 1.08) in the second trimester and 1.12 (1.08 to 1.16) in the third trimester. Significant associations were not observed obviously for caesarean delivery, macrosomia and fetal distress. CONCLUSIONS Our results indicate strong, continuous associations of maternal WBC count with increased risks of adverse pregnancy outcomes.

Abstract
Ectopic pregnancy is a pregnancy complication in which the embryo implants outside the uterine cavity. Although medical treatment is chosen first, sometimes a rupture may occur, and surgical treatment may be required. The parameters to predict rupture have been the subject of many studies. This study aimed to compare the efficacy of different methotrexate protocols in the treatment of ectopic pregnancy and determine the parameters and methotrexate treatment protocols that can predict the risk of rupture. A total of 128 patients diagnosed with ectopic pregnancy were included in this study. Patients were separated into three categories based on their treatment protocols. Regarding the occurrence of rupture, all three groups were compared. The hematological parameters and methotrexate treatment protocols were analyzed and compared between groups. The mean age was 31.9 years. Parity was significantly higher in patients who received multiple doses of methotrexate compared to the other groups. There were significant variations observed among the groups regarding parity, initial β-hCG values, hematocrit (HTC), and mean corpuscular volume (MCV) (p = 0.048, p < 0.001, p = 0.019, and p = 0.047, respectively). According to receiver operating characteristic analysis, neutrophil-to-lymphocyte ratio (NLR) levels were significantly associated with histopathologically confirmed tubal rupture (p < 0.05). NLR levels should be examined in ectopic pregnancy, and the possibility of rupture should be considered in cases with high NLR levels. The potential of NLR to predict ectopic pregnancy rupture should be explored in multicenter prospective studies.

Abstract
OBJECTIVE Preeclampsia (PE) is a serious and common pregnancy issue. There is a systemic inflammation in PE and it is accompanied by increased oxidative stress, but the clear etiology has not been revealed. We aimed to predict PE with the systemic immune-inflammation index (SII) value calculated in the first trimester. MATERIAL AND METHODS This is a retrospective study. One hundred fifty-seven pregnant women were included in the study. Twenty-seven pregnant women were excluded from the study. Age, gravida, parity, and hemogram values were recorded in the patients' first visit file records. The time and mode of delivery, birth weight, and APGAR scores were obtained from the file records of the patients. SII was created using the formula (neutrophil x platelet/lymphocyte). Result: The study group included 30 pregnant women who had been diagnosed with PE. The control group consisted of the remaining 100 pregnant women. There was a statistically significant difference between PE and control groups in terms of SII (p=0.03). The SII level cut-off value for predicting PE was determined to be 836.83. This value's area was found to be 0.635 (0.519-0.752). Furthermore, the selectivity is 0.60 and the sensitivity is 0.40 for these values. Conclusion: SII was found to be significantly higher in people with PE in the study. We showed that the SII value measured in the first trimester can be used to predict PE. It might make sense to combine this marker with the patient's history and other risk factors due to its low selectivity and sensitivity.

Abstract
Purpose To investigate the role of neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) in the prediction of spontaneous preterm birth. Patients and Methods Data was retrospectively collected from hospital record between February 2018 and November 2022. Pregnant women (n = 78) with a single pregnancy between 24 and 34 weeks of gestation, presented with labor pain, and had regular uterine contractions (threatened preterm labor - TPL) were included. Patients delivered within the first week after TPL were included in group 1 (n = 40) and who delivered after in group 2 (n = 38). Two groups were investigated for NLR and PLR values. Results The median cervical length among women who gave birth within a week was significantly lower (24.5 versus 30.0 p < 0.001). The median neutrophil-to-lymphocyte ratio among women who gave birth within a week was significantly higher (6.4 versus 4.5 p < 0.001). The median platelet-to-lymphocyte ratio among women who gave birth within a week was significantly higher (151 versus 131 p < 0.001). The cut-off values to predict preterm birth were >5 for NLR (sensitivity: 90%, specificity: 92.1%), >139 for PLR (sensitivity: 97.5%, specificity: 100%). Conclusion NLR and PLR values predict spontaneous preterm birth with high sensitivity and specificity. By predicting preterm birth, the pregnancy process can be managed sensitively and smoothly.

Abstract
Background Preeclampsia (PE) is one of the highest-risk pregnancies and a complicated condition that occurs in 2% to 8% of pregnancies and is associated with markers of a systemic inflammatory response (SIR). In this study, we aimed to determine the role of these markers in predicting PE. Methodology A total of 300 women with singleton pregnancies and cephalic presentation were included in the study. Normotensive pregnant women (n = 149) who met this criterion were included as the control group Pregnant women who met the inclusion criteria for a diagnosis of preeclampsia (n = 151) were included in the study group. Results The baseline characteristics of the study groups showed no significant difference. The hypertensive group was hospitalized significantly earlier than the control group (p < 0.001). We found significantly higher systolic and diastolic blood pressure values in the PE group than in the other group (p < 0.001). The mean neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and aspartate aminotransferase-to-platelet ratio index (APRI) values at hospitalization did not differ significantly between groups (p = 0.639, p = 0.709, and p = 0.066, respectively). In the receiver operating characteristic analysis curves compared with the control group and PE, none of the parameters could predict PE. Conclusions We found that NLR, PLR, and APRI have no clinical significance in assessing developmental risk and predicting PE.

Abstract
Objective: Placental abruption (PA) is an obstetric emergency. This study investigated the use of platelet indices in PA in its early stages to determine if it could aid in diagnosis. Materials and Methods: Sixty-two pregnant women with PA and 130 pregnant women who delivered due to idiopathic preterm delivery were included in this case-control study. Blood samples including platelet indices, biochemical, and coagulation parameters were obtained before cesarean section. Maternal and neonatal outcomes were recorded. Results: There was no significant difference between the groups as to hemoglobin, hematocrit, and white blood count. Platelet, mean platelet volume (MPV), and platelet to lymphocyte ratio (PLR) were significantly lower, platelet distribution width (PDW) was significantly higher in the PA patients. Conclusion: In the current study, MPV and PLR were lower and PDW was higher in PA patients. These parameters may be useful in assessment of PA.

Neutrophil-to-lymphocyte ratio (NLR) as a predictive index for liver and coagulation dysfunction in preeclampsia patients. BMC Pregnancy Childbirth 2023; 23:4. [PMID: 36600195 DOI: 10.1186/s12884-022-05335-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 12/24/2022] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Pre-eclampsia (PE) is a pregnancy disorder that is related to an enhanced immune response. Immune cell characteristics such as neutrophil or monocyte to lymphocyte ratios (NLR, MLR) are known to be related to kidney and liver dysfunction in hypertensive patients. Here, we aimed to analyze the correlations between NLR, MLR and platelet to lymphocyte ratio (PLR) and liver, renal and coagulation functional parameters and the impacts of these immune cell profiles to the prognostic significance in PE patients. METHODS Pre-delivery hematological and biochemical parameters of 320 first-time pregnant women registered at the Obstetrics Department of Yanbian University Hospital from 2016 to 2019 were analyzed retrospectively. Patients were divided into normal pregnancy (normal, n = 161), mild PE (mPE, n = 28) and severe PE (sPE, n = 131) groups according to diagnostic criteria. Pearson correlation analysis were performed and area under the curve (AUC) were conducted for the diagnostic values of NLR, MLR and PLR. Results were validated with data from the Department of Obstetrics and Gynecology of Seoul National University Hospital (SNUH). RESULTS Kidney functional indexes were adversative in mPE and sPE and liver and coagulation indexes were worse in sPE compared to normal groups. Among immune cells, lymphocytes were increased in mPE and sPE patients, resulted in reduced NLR, MLR and PLR in PE groups, more significant difference were shown in sPE. NLR and PLR were associated with CREA and/or BUN negatively and positive associations were observed with total protein (TP) and albumin (ALB) in sPE. Only NLR showed positive associations with coagulation indexes (PT and APTT) in sPE. AUC analysis for NLR, MLR and PLR were 0.700, 0.656, 0.643, respectively, and NLR < 3.7 predicted hypertension (95% CI in all participants: 0.647-0.749, p < 0.001). Blood pressure, liver, kidney and coagulation indexes were worse at cut off value (NLR < 3.7), and this was validated with the data from SNUH. CONCLUSION NLR could be used as an independent predictor of liver and coagulation dysfunction in PE patients. Our results may provide non-invasive and efficient way of the risk assessment among PE patients.

AIM Adnexal torsion remains a diagnostic challenge due to the nonspecific symptoms, sonographic features, and laboratory findings. The value of combining clinical, sonographic, and laboratory features is not well established, and controversy continues regarding their value in diagnosis. This study aimed to review sonographic, clinical, and laboratory features and to analyze their value separately and in combination, in managing and diagnosing adnexal torsions. METHODS The study included 278 women who underwent urgent laparoscopic surgery due to suspected adnexal torsion, according to clinical suspicion, with or without sonographic concordance. Laparoscopy findings confirmed the definitive diagnosis of torsion. Clinical laboratory and sonographic features were compared between those with and without adnexal torsion. RESULTS Adnexal torsion was confirmed in 110/278 (39.6%) women. In the torsion compared to nontorsion group, proportions were higher of women with acute abdominal pain in the preceding 24 h ([50] 45.5% vs. [35] 20.8%, p < 0.001), with vomiting ([45] 40.9% vs. [24] 14.3%, p < 0.001) and with suspected torsion by transvaginal sonography ([49] 44.5% vs. [23] 13.7%, p < 0.001). A high neutrophil-to-lymphocyte ratio (>3) was identified in 65 (59.1%) of the study group and 60 (35.7%) of the control group (p < 0.001). Combining the latter three findings, the predicted probability of torsion was 58%-85%, depending on the combinations. CONCLUSIONS A simple predictive model based on combinations of clinical, laboratory, and sonographic findings can contribute to preoperative diagnosis of adnexal torsion, with predicted probability of 85%. Our model may assist clinicians in evaluating women with suspected adnexal torsion, and improve preoperative diagnostic accuracy.

The Predictive Role of Maternal Biological Markers and Inflammatory Scores NLR, PLR, MLR, SII, and SIRI for the Risk of Preterm Delivery. J Clin Med 2022; 11:jcm11236982. [PMID: 36498555 PMCID: PMC9738289 DOI: 10.3390/jcm11236982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 11/23/2022] [Accepted: 11/25/2022] [Indexed: 11/29/2022] Open
Abstract
In many countries, preterm birth, defined as birth before 37 completed weeks of gestation, is the primary cause of infant death and morbidity. An increasing body of research suggests that inflammation (both clinical and subclinical) plays a significant role in inducing preterm labor or developing pregnancy problems that lead to premature birth. Consequently, the purpose of this research was to determine the predictive value of the Neutrophil-Lymphocyte Ratio (NLR), derived Neutrophil-Lymphocyte Ratio (dNLR), Monocytes-to-Lymphocyte Ratio (MLR), Platelets-to-Lymphocyte Ratio (PLR), Systemic immune-inflammation index (SII), and systemic inflammatory response index (SIRI), for premature delivery. A retrospective study analyzed a total of 243 eligible pregnancies that resulted in a preterm birth during 2020 and 2021. A control group without a history of preterm birth was matched by age and trimester of laboratory analysis at a 1:1 ratio. Although the number of comorbidities was similar among study groups, the body-mass index estimated for the week of gestation was significantly higher among the patients from the prematurity group, as well as the prevalence of urinary tract infections and smoking. Laboratory data showed that patients with a preterm birth had significantly higher white blood cell count and monocytes, but significantly lower lymphocytes, platelets, and hemoglobin. The NLR, dNLR, PLR, and MLR scores showed to be significantly higher among patients from the prematurity group, but SII and SIRI were not significantly different between the study groups. It was observed that the AUC values of NLR, dNLR, PLR, and MLR were higher than 0.600, respectively NLR had the highest value among the tested scores (AUC = 0.694) and the highest sensitivity in this study (71%). The highest sensibility was achieved by dNLR, with 70%, and an AUC value of 0.655 (p-value = 0.022). PLR had the second-highest AUC value (0.682) and the best score in terms of sensitivity (70%) and sensibility (69%) (p-value = 0.015). Lastly, MLR had the lowest significant AUC score (0.607) and lowest sensitivity/sensibility. The significant cut-off values for the inflammatory scores were 9.0 for NLR, 9.8 for dNLR, 250 for PLR, and 4.07 for MLR. After evaluating the importance of these inflammatory scores, further clinical applications should be conducted to confirm the results and improve therapy and care to reduce the burden of premature deliveries.

Abstract
We aimed to determine predictive values of the platelet count (PC), Neutrophil lymphocyte ratio (NLR), and platelet lymphocyte ratio (PLR) in preeclampsia independently and in combination. One hundred and eighty pregnant women (96 normal pregnancies, 84 preeclampsia) were included in this study. ROC evaluated the predictive value of PC, NLR, and PLR. AUC, Youden's index, and optimal cut-off thresholds were calculated independently and in combination. The PC significantly decreased in preeclampsia (p < .0001, 95% CI -60.6437 to -24.5963) with cut-off level ≤250.3, whereas NLR was significantly increased in preeclampsia (5.28 ± 4.77, p = .0001, 95% CI 0.9813-2.9187) with cut-off level >4.47. In preeclampsia, PLR significantly decreased (94.32 ± 30.81, p = .0001, 95% CI 58.2583 to -29.6817) with cut-off level ≤100.48. Combined indices of PC, NLR, and PLR were significantly more predictive of preeclampsia when compared to independent indices (AUC 0.86, p < .001, 95% CI 0.801-0.907, sensitivity 75.0, and specificity 81.2) compared to independent indices.IMPACT STATEMENTWhat is already known on this subject? Many studies have tried to find out a simple screening test that would predict the risk of developing preeclampsia. Platelet count, Neutrophil lymphocyte ratio, and platelet lymphocyte ratio have been investigated independently to predict preeclampsia. These parameters are simple, cheap, and are usually available for all patients. Unfortunately, there are no universal cut-off levels accepted.What do the results of this study add? The use of a combination of platelet count, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio is a simple and effective test to predict preeclampsia. The use of a scoring system involving cut-off levels of platelet count, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio is a highly predictive index for developing preeclampsia.What are the implications of these findings for clinical practice and/or further research? In this study, we aimed to highlight the importance of using a combination of platelet count, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio as a scoring index instead of using these parameters independently. More studies are needed to reach a universal cut-off level for each parameter.

Abstract
Background The neutrophil-lymphocyte ratio (NLR) is easily calculated blood test parameter, which can be used as marker to predict many inflammatory disorders. The aim of this study was to assess and compare the NLR in maternal blood with the white blood cell (WBC) count and C-reactive protein (CRP) concentration for the prediction of histological chorioamnionitis. Methods This was a case-control study of 137 woman with preterm premature rupture of membranes (PPROM) at a gestational age between 22+ 0 and 34+ 6 weeks. Blood samples, collected less than 48 h before delivery and at least 48 h after the administration of corticosteroids, were selected for the analysis. The NLR was calculated by dividing the number of neutrophils by the number of lymphocytes. Chorioamnionitis was diagnosed by the histopathological evaluation of placental membranes and chorionic plate. Results Patients with diagnosed histological chorioamnionitis (HCA) had significantly higher levels of WBC, CRP and NLR (p-value < 0.001). Levels of WBC, CRP and NLR predicted HCA with an area under the curve (AUC) of 0.81, 0.81 and 0.89, respectively. NLR had statistically significantly higher AUC than WBC, but no significant difference was found between AUCs of NLR and CRP. The cut-off level of NLR was found to be 5,97, which had a sensitivity of 77 % and a specificity of 95 %. Conclusion NLR has a good predictive value for HCA and could be used as an additional diagnostic marker for predicting histological chorioamnionitis in cases with preterm premature rupture of membranes before 34 weeks of gestation.

Abstract
OBJECTIVE To determine the correlation between the levels of serum markers in the second trimester and preterm birth before 34 weeks in asymptomatic twin pregnancies. METHODS We conducted a retrospective review of the medical records of 102 asymptomatic twin pregnancies delivered at Chilgok Kyungpook National University Hospital between March 2014 and February 2020. Participants were divided into two groups, based on delivery before and after 34 weeks of gestation. Results of the quad test performed at 15-18 weeks and the complete blood count done at 24-28 weeks were compared. RESULTS Preterm birth before 34 weeks of pregnancy was associated with higher levels of maternal α-fetoprotein (1.04 vs 0.98, multiple of median [MoM], P = 0.006), human chorionic gonadotropin (1.76 vs 1.31, MoM, P = 0.000), and inhibin A (1.78 vs 1.04, MoM, P = 0.000). Positive correlations were observed between gestational age at delivery and white blood cell (WBC) markers. Women with preterm delivery had decreased WBC counts (8180 vs 9405 × 103 /µl, P = 0.019) and neutrophil:lymphocyte ratios (3.85 vs 4.92, P = 0.001). CONCLUSION Serum marker levels in the second trimester can be indicators of preterm delivery before 34 weeks in asymptomatic twin pregnancies.

Abstract
OBJECTIVE We aimed to compare the diagnostic efficiency of cystatin C with traditional kidney markers in preeclampsia and to evaluate the relationship of these markers with neutrophil-lymphocyte and thrombocyte-lymphocyte ratios. MATERIALS AND METHODS 14 severe preeclampsia, 48 mild preeclampsia and 79 patients with healthy pregnancy who presented to our obstetrics and gynecology clinic within one year were compared. These three groups were compared in terms of demographic characteristics, physical findings, serum urea, creatinine, cystatin C levels, and neutrophil-lymphocyte and platelet-lymphocyte ratios. RESULTS The mean serum cystatin C, creatinine and uric acid levels were higher in the severe preeclampsia group compared with the mild preeclamptic and healthy pregnancies (p < 0.001). While cystatin C values increased as the week of gestation increased in the mild preeclampsia group, there was no relation with the gestational week in the control group and the severe preeclampsia group. However, the highest cystatin C values were in the severe preeclampsia group, regardless of the week (p < 0.05). The area under the ROC curve was statistically significant for cystatin C, uric acid and creatinine, but of these three values, cystatin C had the highest sensitivity and specificity. Neutrophil-lymphocyte ratio (NLR) was significantly higher in the severe preeclampsia group than healthy pregnancies, but the level was not significant compared to mild preeclampsia. There was no difference between the groups in terms of platelet-lymphocyte ratio. CONCLUSION It can be suggested that cystatin C level reflects renal functions better than uric acid and creatinine in preeclampsia. Cystatin C can be used as a prognostic marker in preeclamptic pregnancies, and rising levels may be valuable for predicting severe preeclampsia. Especially with advancing gestational week, the increase in cystatin C level may indicate an association with the development of preeclampsia. NLR levels may be a parameter correlating with severity in severe preeclampsia.

Neutrophil to Lymphocyte Ratio in Maternal Blood: A Clue to Suspect Amnionitis. J Clin Med 2021; 10:jcm10122673.

Abstract
There is no information about whether maternal neutrophil to lymphocyte ratios (NLRs) progressively increase with respect to the progression of acute histologic chorioamnionitis (acute-HCA) and increased maternal NLR is a risk factor for amnionitis, known as advanced acute-HCA, in pregnant women at risk for spontaneous preterm birth (PTB). The objective of the current study is to examine this issue. The study population included 132 singleton PTB (<34 weeks) due to either preterm labor or preterm-PROM with both placental pathology and maternal CBC results within 48 h before delivery. We examined maternal NLRs according to the progression of acute-HCA in extra-placental membranes (EPM) (i.e., group-0, inflammation-free EPM; group-1, inflammation restricted to decidua; group-2, inflammation restricted to the membranous trophoblast of chorion and the decidua; group-3, inflammation in the connective tissue of chorion but not amnion; group-4, amnionitis). Maternal NLRs significantly and progressively increased with the progression of acute-HCA (Spearman’s rank correlation test, γ = 0.363, p = 0.000019). Moreover, the increased maternal NLR (≥7.75) (Odds-ratio 5.56, 95% confidence-interval 1.26-24.62, p < 0.05) was a significant independent risk factor for amnionitis even after the correction for potential confounders. In conclusion, maternal NLRs significantly and progressively increased according to the progression of acute-HCA and the increased maternal NLR (≥7.75) was an independent risk factor for amnionitis in spontaneous PTB. The evaluation of the performance of NLR should clearly require a prospective description of this parameter in a cohort of patients with either threatened PTL or preterm-PROM.

Abstract
We aimed to evaluate the effectiveness of changes over time in complete blood count (CBC) parameters to estimate the diagnosis of preeclampsia. Data on 161 severe preeclampsia patients and 161 healthy pregnant patients who met the study criteria of pregnant women whose CBC had been measured at 10-12, 22-24 and 28-30 weeks of pregnancy were compared. In the preeclampsia group, an increase in the mean platelet volume (MPV) value and a decrease in the number of platelets were statistically significant in the transition from the second to the third trimester. MPV and lymphocyte counts were more significant in the third trimester and neutrophil lymphocyte ratio (NLR) were more significant in the second trimester. We found that evaluation of the changes in lymphocyte, MPV and NLR values in three different trimesters of pregnancy rather than a single trimester was more meaningful to predict severe preeclampsia.Impact StatementWhat is already known on this subject? Studies have shown that MPV and NLR can predict preeclampsia. However, a clear cut off value could not be determined. The reasons for this may be that the gestational week during which the measurement is made is not standard and the patient groups are not homogeneous.What the results of this study add? In this study, CBC parameters at different stages of the preeclampsia process were compared in the severe preeclampsia group. According to our results, lymphocytes, NLR and MPV can be used to predict severe preeclampsia. In addition, NLR measurements in the second trimester and MPV and lymphocyte measurements in the third trimester were found to be more significant in predicting severe preeclampsia.What the implications are of these findings for clinical practice and/or further research? In order to predict severe preeclampsia, instead of a single measurement of CBC parameters, new calculations should be made that add change over time.

OBJECTIVE Placental abruption (PA) is associated with adverse maternal and neonatal outcomes. Increasing evidence has shown an association between abruption and inflammation as well as utilization of hematological biomarkers to predict the later. We aimed to evaluate the feasibility of using neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ration (PLR) taken early in pregnancy in predicting later occurrence of PA. STUDY DESIGN A nested case control study, which compared parturient with PA (cases) to parturient without PA (controls). Parturient were matched by hospitalization date and maternal age. Demographic, clinical, and obstetrical characteristics were retrieved. Hematological indices derived from complete blood count taken during the first trimester of pregnancy, specifically NLR and PLR were retrieved and compared between the groups. Mann-Whitney and T-test were performed for not normally and normally distributed continuous variables respectively, categorical variables were analyzed using Chi-Square or Fisher Exact test as appropriate. RESULTS The study comprised of 232 patients. Of these, 131 had suffered from PA and 131 without PA. Parturient who had PA has significantly higher rates of hypertensive disorders of pregnancy, mean neutrophil, lymphocyte and platelet count did not differ between the groups. A comparison of NLR and PLR between the study groups yielded no significant differences. CONCLUSION NLR and PLR taken early in the course of pregnancy were not found associated with PA. Given the potentially severe consequences of PA, the biological plausibility and the readiness of these hematological markers, further investigation of this method with larger, prospective studies are needed.

Abstract
OBJECTIVE To evaluate the efficacy of complete blood count indices for the prediction of miscarriage. MATERIALS AND METHODS A retrospective case-control study was conducted in a tertiary hospital. This study consisted of 389 cases (32 elective and 193 spontaneous abortions, 164 healthy pregnancies). Maternal demographic characteristics, complete blood cell (CBC) parameters, neutrophil-lymphocyte ratio (NLR), derived NLR, systemic inflammatory immune index (SII), platelet-to-lymphocyte ratio (PLR), and delta neutrophil index (DNI) that were in the routine first trimester CBC were compared between groups. RESULTS There were no significant differences among groups in terms of demographic and obstetric characteristics. Statistically significant differences were observed for Hb, white blood cell (WBC), lymphocyte (L), NLR, SII, and PLR between the subgroups (p=0.003, p=0.045, p=0.000, p=0.002, p=0.043, p=0.010, respectively). There were no significant differences among groups in terms of the remaining parameters. When healthy pregnancies and spontaneous abortions were compared, statistically significant differences were detected for NLR, SII, PLR (p=0.001, p=0.039, and p=0.000, respectively). Moreover, when healthy pregnancies and elective abortions were compared, only NLR was found as statistically different (p=0.050). Area under curve (AUC) was calculated for PLR as 0.659 (%95 CI: 0.582-0.735) and a cut-off value of 158.1 was found with highest sensitivity and specificity (60.6 % and 61.6%, respectively) according to the results obtained from Youden's index. AUC was calculated for NLR as 0.591 (%95 CI: 0.507-0.675) and a cut-off value of 3.135 was found with highest sensitivity and specificity (56% and 54.5%) according to the results obtained from Youden's index. CONCLUSION In conclusion, decreased PLR and NLR levels may be used as practical and cost-effective markers for the prediction of miscarriages.

Abstract
OBJECTIVE To evaluate the predictive value of the first-trimester aspartate aminotransferase (AST)/platelet count ratio [AST to platelet ratio index (APRI) score] for intrahepatic cholestasis in pregnancy (ICP). METHODS This study consisted of a patient group diagnosed with ICP (n = 37) and a control group (n = 66) who presented to the hospital perinatology clinic between 2018 and 2020. Laboratory tests of both groups were analysed retrospectively. Age, gravida, parity, body mass index, third-trimester laboratory tests and first-trimester APRI scores were compared between the two groups. A receiver operating characteristic (ROC) analysis of the study was performed to determine the cut-off value for APRI score that is predictive of ICP. RESULTS Patients with ICP had significantly higher first-trimester APRI scores compared with controls (p < 0.001). In the ROC analysis, the cut-off value for APRI score was 0.57, with 86.5 % sensitivity and 77.3 % specificity. Spearman's correlation indicated that there was a significant positive association between first-trimester APRI score and third-trimester fasting bile acid level (r = 0.641, p < 0.001). The demographic characteristics of patients in the third trimester did not differ, except for AST and alanine transferase values. CONCLUSIONS The APRI score calculated in the first trimester of pregnancy seems to be predictive of the development of ICP in the third trimester.

Abstract
OBJECTIVE To evaluate whether neutrophil-to-lymphocyte ratio (NLR), a well-established inflammatory marker, can be used as an early predictor for small-for-gestational-age (SGA) neonates and other adverse pregnancy outcomes. METHODS A case-control study compared first-trimester hematological biomarkers in pregnancies of patients with and without SGA (n=149, n=151, respectively). Demographic, clinical, and obstetrical characteristics and first-trimester complete blood count were retrieved. Woman with singleton pregnancies who delivered at Soroka University Medical Center between January 2015 and December 2016 were included. Patients with known maternal infections, relevant medications, hematological conditions, and chronic diseases that may alter the blood count, those with multiple pregnancies, and those with congenital or chromosomal abnormalities were excluded. After univariate analysis, a linear regression model was constructed to assess the association between hematological indices and SGA. Receiver operating curves were constructed to evaluate the sensitivity and specificity of NLR. RESULTS First-trimester NLR values of the SGA group were significantly higher compared to controls (3.03 ± 1.68 vs 2.63 ± 1.2, P=0.016). Significantly higher levels of NLR were noted among the severely (<3%) SGA neonates (3.12 ± 1.62 vs 2.62 ± 1.2; P=0.034). CONCLUSION NLR may be an early, clinically useful marker in the prediction of SGA. As blood samples are routinely collected, correct implication of this result may serve as a valuable non-invasive, low-cost, readily available predicting tool.

Abstract
AIM To explore whether neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) could predict missed abortion (MA) at 7-13 week's gestation. METHODS A total of 363 women with a diagnosis of MA and 232 women with normal pregnancy at 7-13 week's gestation, who visited our hospital from June 2012 to May 2018 were retrospectively analyzed. At 7 week's gestation, total and differential leukocyte counts, NLR and MLR were compared between women with MA (n = 69) and normal controls (n = 53). The receiver operating characteristic curve was used to select the optimal indicator and its cut-off point. The role of the optimal indicator was further assessed at 8-13 week's gestation. RESULTS The mean white blood cell counts, the mean neutrophil counts, the median monocyte counts, the mean NLR and the median MLR in women with MA were significantly lower than those in normal controls (P < 0.05, respectively).The neutrophil counts had the highest area under the curve (AUC) value of 0.772 (95% confidence interval 0.675-0.869) with a cut-off value of 4.870 × 109 /L, and the sensitivity was 72.46%, the specificity was 69.81%, positive predictive value was 75.76%, and negative predictive value was 66.07%. In addition, the neutrophil counts were also significantly lower in MA groups than those in normal controls at 8-13 week's gestation, and all had the highest AUC values. CONCLUSION Neutrophil counts may predict MA in the first trimester of pregnancy, which may provide a promising marker to diagnose missed abortion as early as 7 week's gestation.

Abstract
BACKGROUND Neutrophil-lymphocyte ratio (NLR) is one of the markers of systemic inflammation. Recent studies have associated NLR with diagnosis of preeclampsia (PE). However, due to small sample sizes and different research design, the diagnostic value of NLR in PE patients is not well understood. In this study, we evaluate the potential diagnostic value of NLR in PE. METHODS We searched PubMed, Embase, Cochrane Library, the Chinese National Knowledge Infrastructure (CNKI) databases, Wanfang data, VIP database and China Biomedical Literature Database systematically for relevant literatures up to May 20, 2018. All analyses were conducted using Meta-DiSc1.4 and Stata 12.0 software. Sensitivity, specificity and other measures of accuracy of NLR for the diagnosis of PE were pooled. Meta-regression was performed to identify the sources of heterogeneity. RESULTS This meta-analysis included a total of 7 studies. The pooled sensitivity and specificity were 0.74 (95% CI 0.71-0.76) and 0.64 (95%CI 0.61-0.68), positive likelihood ratio, 2.62 (95%CI1.79-3.84); negative likelihood ratio, 0.34 (95%CI 0.24-0.48); diagnostic odds ratio, 8.44 (95%CI 4-17.78), and area under the curve was 0.82. Meta regression showed that sample size was the main source of heterogeneity. Deeks funnel plot showed that there was no statistical significance for the evaluation of publication bias (P = .16). CONCLUSION Current evidence suggests that the diagnostic accuracy of NLR has unsatisfactory specificity but acceptable sensitivity for diagnosis of PE. Further large-scale prospective studies are required to validate the potential applicability of using NLR alone or in combination other markers as PE diagnostic biomarker and explore potential factors that may influence the accuracy of NLR for PE diagnosis.

Abstract
The aim of the study was to investigate peripheral blood platelets, neutrophils and lymphocytes counts in women with preterm premature rupture of membranes (PPROM) and threatened preterm labour (TPL) compared with gestation-matched controls in order to learn how they change. This study was conducted on 60 women with PPROM, 50 women with TPL and 47 healthy pregnant women. Laboratory parameters (including complete blood count, C-reactive protein (CRP)) of all the participants were recorded. The neutrophil-to-lymphocyte ratio (NLR) values were significantly higher in PPROM group than TPL group and healthy control group (6.1 ± 3.9, 4.4 ± 1.7, 4.4 ± 2.2, p = .007, p = .018, respectively). At a cut-off level of 5.14, NLR accurately predicted occurrence of neonatal sepsis (AUC = 0.717 (95% confidence interval 0.610-0.824), p = .001) with sensitivity and specificity rates of 69.7% and 72.0%, respectively. In the management of the patients with PPROM, NLR can be used as a more cost-effective method than other blood parameters that require the use of a kit.IMPACT STATEMENTWhat is already known on this subject? There is only one study in the literature evaluating blood count parameters (such as platelet-to-lymphocyte ratio (PLR), NLR) in PPROM pregnancies. That study demonstrated PLR and NLR were both higher in the PPROM group.What do the results of this study add? The present study demonstrates that only NLR is higher in the PPROM group. Furthermore, we have also demonstrated distinctively that NLR can predict occurrence of neonatal sepsis.What are the implications of these findings for clinical practice and/or further research? High values of NLR may be useful for predicting adverse outcomes in PPROM and TPL patients as a cost-effective method. Further studies are needed to determine whether these parameters can be used to predict if a pregnant woman who is at risk of preterm labour will result in adverse perinatal outcome.

Abstract
OBJECTIVE To investigate the association between maternal serum neutrophil-lymphocyte ratio (NLR) and placental inflammatory response (PIR) in late pregnancy. METHODS We retrospectively analyzed the clinical and follow-up data of 478 pregnant women undergoing routine prenatal examination and delivery in our hospital in the year 2016. According to the placental pathological results, the women were divided into PIR group (238 cases) and control group (240 cases). The levels of serum inflammatory makers including leukocytes, neutrophils, lymphocytes, C-reactive protein (CRP) and NLR were compared between the two groups to analyze the association of these markers with PIR. Multivariate analysis was performed to identify the independent risk factors of PIR. Logistic regression model was established and the area under the receiver operating characteristic curve (ROC) was used for analyzing the prognostic value of these makers in late pregnancy. RESULTS The areas under the curve (AUC) of leukocytes, neutrophils, lymphocytes, CRP and NLR were 0.698 (95%CI: 0.485-0.766), 0.716 (95%CI: 0.453-0.783), 0.329 (95%CI: 0.228-0.431), 0.725 (95%CI: 0.677-0.765) and 0.801 (95%CI: 0.742-0.856), respectively. After adjusting the confounders, multivariate logistic regression analysis showed that preterm labor (OR=2.446, 95%CI: 1.003-4.590), premature rupture of membranes (OR=2.304, 95%CI: 1.049-4.161), NLR > 7 (OR=3.268, 95%CI: 2.071-6.920), and CRP > 15 mg/L (OR=2.137, 95%CI: 1.412-8.236) were independent risk factors for PIR. CONCLUSIONS An increased NLR in late pregnancy can serve as an effective indicator for predicting the risk of PIR.

Abstract
OBJECTIVE To compare the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and platelet indices between women with pre-eclampsia and normotensive pregnant women. METHODS A cross-sectional study conducted from January to July 2017 at a tertiary care hospital in Delhi, India. The study compared pregnant women aged 18-40 years with pre-eclampsia diagnosed at term with healthy pregnant women matched for gestational age. Venous blood samples were drawn and complete blood count was analyzed. The parameters recorded were hemoglobin, red cell distribution width (RDW), platelet count, mean platelet volume (MPV), plateletcrit, and platelet distribution width. RESULTS There were 67 women included in each group. NLR was higher in women with pre-eclampsia compared with the control group (6.8 ± 7.6 vs 3.0 ± 0.98; P=0.001). Both PLR (14.18 ± 14.4 vs 9.54 ± 3.6; P=0.012) and MPV (9.45 ± 1.19 vs 9.02 ± 1.1; P=0.029) were higher in the study group compared with the control group. Platelet count was lower in pre-eclamptic women compared with the control group (188 ± 89.7 vs 200.1 ± 62.36; P=0.014). RDW was also higher in the study group (P=0.025). CONCLUSIONS The present study found that the inflammatory markers NLR, PLR, RDW, and MPV were higher in women with pre-eclampsia. Measuring NLR and PLR may be useful in predicting pre-eclampsia among women at high risk during prenatal follow-up.

INTRODUCTION The appearance of preeclampsia (PE) would comprise the alteration of endothelial function and activation of the inflammatory response, leading to placental hypoperfusion. The neutrophil/lymphocyte ratio (NLR) and the polymorphonuclear/monomorphonuclear ratio (PMR) could measure the underlying inflammatory component and predict the onset of the disorder. MATERIAL AND METHODS Observational, analytical, case and control study. We retrospectively analysed medical records of pregnant women, hospitalized for hypertension registers. The patients were divided into Group1=with PE development, and Group2=without PE development. RESULTS 110 patients were included: Group1=58.2% and Group2=41.8%, observing differences between the NLR means (P=.01) and PMR means (P=.02). An NLR ≥4.5 (P=.002; OR=3.9; 95%CI=1.6-9.5) and a PMR ≥3 (P=.004; OR=3.5; 95%CI=1.4-8.4) was related with PE. CONCLUSION The elevation of NLR and PMR in hypertensive pregnant patients, could be considered indicators for the development of PE.

Oxidative stress and endothelial function in normal pregnancy versus pre-eclampsia, a combined longitudinal and case control study. BMC Pregnancy Childbirth 2018; 18:60.

Abstract
Background Pre-eclampsia (PE) is related to an impaired endothelial function. Endothelial dysfunction accounts for altered vascular reactivity, activation of the coagulation cascade and loss of vascular integrity. Impaired endothelial function originates from production of inflammatory and cytotoxic factors by the ischemic placenta and results in systemic oxidative stress (OS) and an altered bioavailability of nitric oxide (•NO). The free radical •NO, is an endogenous endothelium-derived relaxing factor influencing endothelial function. In placental circulation, endothelial release of •NO dilates the fetal placental vascular bed, ensuring feto-maternal exchange. The Endopreg study was designed to evaluate in vivo endothelial function and to quantify in vitro OS in normal and pre-eclamptic pregnancies. Methods/design The study is divided into two arms, a prospective longitudinal study and a matched case control study. In the longitudinal study, pregnant patients ≥18 years old with a singleton pregnancy will be followed throughout pregnancy and until 6 months post-partum. In the case control study, cases with PE will be compared to matched normotensive pregnant women. Maternal blood concentration of superoxide (O2•) and placental concentration of •NO will be determined using EPR (electron paramagnetic resonance). Endothelial function and arterial stiffness will be evaluated using respectively Peripheral Arterial Tonometry (PAT), Flow-Mediated Dilatation (FMD) and applanation tonometry. Placental expression of eNOS (endothelial NOS) will be determined using immune-histochemical staining. Target recruitment will be 110 patients for the longitudinal study and 90 patients in the case-control study. Discussion The results of Endopreg will provide longitudinal information on in vivo endothelial function and in vitro OS during normal pregnancy and PE. Adoption of these vascular tests in clinical practice potentially predicts patients at risk to develop cardiovascular events later in life after PE pregnancies. •NO, O2•− and eNOS measurements provide further inside in the pathophysiology of PE. Trial registration This trial has been registered on clinicaltrials.gov. ClinicalTrials.gov Identifier: NCT02603913. Registered October 2015.

Abstract
OBJECTIVE Preeclampsia (PE) is a severe pregnancy complication with significant maternal and neonatal morbi-mortality resulting in high health care costs. Prevention, mainly based on the administration of acetylsalicylic acid, is only possible if timely identification of high-risk patients can be realized in an easy, nonexpensive, and widely available method. This paper explores the clinical usability of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and/or mean platelet volume (MPV) in discriminating between women that will and those that will not develop PE. STUDY DESIGN Demographic data and laboratory results were retrospectively collected and compared in 2050 pregnant women (164 PE and 1886 controls) between 1 January 2014 and 31 January 2016. RESULTS In the PE group, gravidity, parity, gestational age, and birth weight were significantly lower compared to the control group. Before the 20th pregnancy week, MPV was significantly elevated in the PE group compared to the controls (p = .006), hence analysis revealed an optimal cut-off point of 8.15 (sensitivity 66.7%, specificity 56.3%) for predicting PE. At the end of pregnancy, NLR and MPV appeared to be higher and PLR lower in the PE group compared to the controls, which strengthens the current knowledge on the pathogenesis of PE. CONCLUSIONS MPV is significantly elevated in the first half of pregnancy in women who later develop PE and might therefore be implemented in combination with other parameters in a PE prediction model.

Abstract
Purpose Vitamin D plays a key role in immune function. Vitamin D deficiency may play a role in the pathogenesis of infections, and low levels of circulating vitamin D are strongly associated with infectious diseases. In this study, we aimed to evaluate the effects of low vitamin D levels in cord blood on neonatal sepsis in preterm infants. Methods One hundred seventeen premature infants with gestational age of <37 weeks were enrolled. In the present study, severe vitamin D deficiency (group 1) was defined as a 25-hydroxyvitamin D (25(OH)D) concentration <5 ng/mL; vitamin D insufficiency (group 2), 25(OH)D concentration ≥5 ng/mL and <15 ng/mL; and vitamin D sufficiency (group 3), 25(OH)D concentration ≥15 ng/mL. Results Sixty-three percent of the infants had deficient levels of cord blood vitamin D (group 1), 24% had insufficient levels (group 2), and 13% were found to have sufficient levels (group 3). The rate of neonatal sepsis was higher in group 2 than in groups 1 and 3. Conclusion There was no significant relationship between the cord blood vitamin D levels and the risk of neonatal sepsis in premature infants.

Abstract
Endothelial function and arterial stiffness are known to be altered in preeclamptic pregnancies. Previous studies have shown conflicting results regarding the best technique for assessing vascular function in pregnancy. In this study, we made a comprehensive evaluation of in vivo vascular function [including flow-mediated dilatation (FMD), peripheral arterial tonometry (PAT), and arterial stiffness] in preeclamptic patients and compared them with normal pregnancies. In addition, we assessed the relation between vascular function and systemic inflammation. Fourteen patients with preeclampsia (PE) and 14 healthy pregnant controls were included. Endothelial function was determined by FMD and PAT and arterial stiffness by carotid-femoral pulse-wave velocity and augmentation index. Systemic inflammation was assessed using mean platelet volume (MPV) and neutrophil-lymphocyte ratio (NLR). The reactive hyperemia index, assessed using PAT, is decreased at the third trimester compared with the first trimester in a normal, uncomplicated pregnancy (P = 0.001). Arterial stiffness is significantly higher in PE versus normal pregnancy (P < 0.001). Endothelial function, obtained by FMD, is deteriorated in PE versus normal pregnancy (P = 0.015), whereas endothelial function assessment by PAT is improved in PE versus normal pregnancy (P = 0.001). Systemic inflammation (MPV and NLR) increases during normal pregnancy. FMD and PAT are disturbed in PE. Endothelial function, assessed by FMD and PAT, shows distinct results. This may indicate that measurements with FMD and PAT reflect different aspects of endothelial function and that PAT should not be used as a substitute for FMD as a measure of endothelial function in pregnancy.

Abstract
Objective: Preterm premature rupture of membranes (PPROM) is closely related with maternal and fetal complications. Therefore, early diagnosis is extremely important to provide maternal and fetal well-being. Many inflammatory markers have been evaluated for their ability to diagnose membrane rupture at early stages. We aimed to investigate the relationship between the platelet-to-lymphocyte ratio (PLR) and preterm premature membrane rupture. Material and Methods: In this study, 121 pregnant women with PPROM and 96 age-matched pregnant women with spontaneous preterm labor who were admitted to our hospital between January 2014 and December 2015 were enrolled. Demographic data, complete blood cell count results, and neonatal outcomes were recorded. Results: The neutrophil and platelet counts were higher in the PPROM group (9948.4±3393.2 vs. 7466.1±1698.5/mm3 and 244.5±60 vs. 210.6±64.8/mm3, respectively, p<0.001). The PLR and neutrophil-to-lymphocyte ratios (NLR) were both significantly higher in the PPROM group (p<0.001). Correlation analysis revealed that the PLR was positively correlated with the NLR (r=0.10, p=0.031). The ability of the PLR to diagnose preterm premature rupture of membranes was evaluated using an ROC curve. The sensitivity and specificity of the PLR was 57.8% and 73.7%, respectively, at a threshold >117.14 (p<0.001). Conclusion: The PLR might be a cost effective, easy to use, and practical marker for the early diagnosis of PPROM, which can help to determine the appropriate waiting time for delivery and provide maternal and fetal well-being.

Abstract
OBJECTIVE We aimed to investigate whether the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) could be utilized to screen for gestational diabetes mellitus (GDM). SUBJECTS AND METHODS NLR and PLR were assessed by retrospective analysis of 762 healthy and pregnant women with GDM. The patients were stratified into four groups, as follows: GDM (n=144), impaired glucose tolerance (n=76), only screen positive (n=238), and control (n=304). RESULTS The leukocyte, neutrophil, and lymphocyte counts were significantly higher in the study groups compared with the control group (P=0.001; P<0.01). There were no statistically significant differences between the groups with respect to the NLR and PLR (P>0.05). CONCLUSION We do not recommend that blood NLR and PLR can be used to screen for GDM. However, increase in the leukocyte count is an important marker for GDM as it provides evidence of subclinical inflammation.

Abstract
AIM The aim of this study was to evaluate the relationship between serum sirtuin-1 (SIRT1) level and neutrophil-lymphocyte ratio (NLR) with hyperemesis gravidarum (HG). METHODS Overall, 90 patients who presented with pregnancy between August 2013 and November 2014 were included in the study. The patients were divided into two groups: patients with HG (n=45) and patients without HG (control group [C]; n=45). The patients with comorbid conditions other than pregnancy (disease or medication) were excluded. In all patients, demographic data including age, body mass index (BMI), gestational week, and smoking status were recorded. Blood samples were drawn for complete blood count and measurements of blood lipid, liver enzymes, serum SIRT1, and insulin levels. NLR was calculated from CBC. RESULTS No significant differences were detected in age, BMI, or GA between groups (P>0.05). Serum SIRT1 and NLR were found to be significantly higher in patients with HG compared with those in the control group (P=0.001 and 0.006, respectively). CONCLUSION In HG, both SIRT1 level and NLR increased. In HG, this occurred as a response to metabolic alterations and potential inflammation.

Abstract
OBJECTIVE To evaluate the relationship of neutrophil/lymphocyte ratio (NLR) with proteinuria and blood pressure level in patients with pre-eclampsia and to investigate whether or not NLR has a role in predicting the severity of pre-eclampsia. STUDY DESIGN The study comprised 30 healthy pregnant females (Group 1), 37 females with mild pre-eclampsia (Group 2) and 40 with severe pre-eclampsia (Group 3). All the study participants were statistically compared in respect of demographic data, proteinuria levels, and blood pressure levels. RESULT Age, body mass index, and gestational weeks were similar in all the groups. Maternal NLR was determined to be significantly high in the pre-eclamptic patients (Groups 2 and 3) compared to the healthy pregnant patients (Group 1) (p=0.017). NLR was significantly higher in the severe pre-eclampsia group than in the mild pre-eclampsia group (p=0.032). A significant positive correlation was determined in correlation analysis between NLR and proteinuria (p=0.013, r=0.319). There was also a significant and positive correlation between NLR and systolic/diastolic arterial pressure (p=0.007, r=0.285; p=0.044, r=0.213, respectively). CONCLUSION In conclusion, while NLR was determined as significantly high in patients with pre-eclampsia, to be able to use this in the classification of the severity of pre-eclampsia, there is a need for further studies on a more extensive population.

Abstract
INTRODUCTION Preeclampsia is a serious disease which may result in maternal and neonatal mortality and morbidity. Improving the outcome for preeclampsia necessitates early prediction of the disease to identify women at high risk. Measuring blood cell subtype ratios, such as the neutrophil to lymphocyte (NLR) and platelet to lymphocyte (PLR) ratios, might provide prognostic and diagnostic clues to diseases. AIM To investigate hematological changes in early pregnancy, using simple complete blood count (CBC) and blood concentrations of beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein-A (PAPP-A) to determine whether these measures are of any value in the prediction and early diagnosis of preeclampsia. MATERIALS AND METHODS Six hundred fourteen consecutive pregnant women with preeclampsia (288 with mild disease and 326 with severe disease) and 320 uncomplicated pregnant women were included in the study. Blood samples for routine CBC and first trimester screen, which combines PAPP-A and free β-hCG blood concentrations, were analyzed. RESULTS The NLR values were significantly higher in the severe preeclampsia group compared with the control group (p<0.001). We also confirmed that levels of PAPP-A were lower in patients who developed preeclampsia. CONCLUSION Because measuring CBC parameters, particularly NLR, is fast and easily applicable, they may be used to predict preeclampsia.
