Abstract
BACKGROUND Hesperidin, a flavanone commonly found in citrus fruits and herbal formulations, has emerged as a potential new therapeutic agent for modulating several diseases. Since pre-eclampsia is a growing public health threat, it may negatively impact the economy and increase the disease burden of South Africa. Phytocompounds are easily accessible, demonstrate minimal side effects, and may confer novel medicinal options as a treatment and preventive preference. OBJECTIVE To investigate the physiological, biochemical, and hematological outcomes of hesperidin in an arginine vasopressin (AVP)-induced rodent model of pre-eclampsia. METHODS Female Sprague-Dawley rats were surgically implanted with mini-osmotic pumps to deliver AVP (200 ng/h) subcutaneously. Animals were treated with hesperidin at 200 mg/kg.b.w via oral gavage for 14 days. Systolic and diastolic blood pressures were measured on GD 7, 14, and 18 using a non-invasive tail-cuff method and were euthanized on GD 21. RESULTS The findings showed that hesperidin administration significantly decreased blood pressure (P < 0.05) and urinary protein levels in pregnant rats (P < 0.001). Placental and individual pup weight also increased significantly in the pregnant hesperidin-treated groups compared to AVP untreated groups (P < 0.001). Biochemical and hematological markers such as white blood cell count and lymphocyte levels differed significantly (P < 0.05) in AVP groups treated with and without hesperidin. CONCLUSION Our results suggest that hesperidin is an antihypertensive agent with modes of action associated with its diuretic and blood pressure lowering effects and reduction of proteinuria in AVP-induced pre-eclamptic rats.

Abstract
INTRODUCTION This research was conducted to assess the effectiveness of red cell distribution width (RDW) as an indicator for pre-eclampsia (PE), a condition characterized by elevated blood pressure and the presence of protein in the urine occurring beyond the 20th week of pregnancy. METHODOLOGY The case-control investigation spanned 10 months, following the acquisition of informed consent and the receipt of ethical clearance. The study sample comprised a total of 70 pregnant women, evenly divided into two groups: 35 cases of PE and 35 normotensive pregnant controls. Both the cases and controls provided 3 ml venous blood samples. The study employed a semi-automated three-part hematological analyzer to establish the baseline RDW for all individuals. RESULTS This study showed that the individuals with pre-eclampsia had a greater RDW compared to the healthy pregnant women. The observed difference was found to be statistically significant, with a p-value of 0.004. The receiver operating curve (ROC) analysis showed that RDW exhibited significant diagnostic accuracy in differentiating between cases and controls (area under the curve [AUC] = 0.71, P = 0.004) when employing a cut-off value of >= 18.25. The sensitivity was 80% and the specificity was 71.4%. CONCLUSION In contrast to other indicators of inflammation, RDW is a cost-effective and easily accessible biomarker that can be acquired from routine complete blood counts. It has the potential to be valuable in predicting and diagnosing pre-eclampsia.

[PMID: 38318431 PMCID: PMC10840323 DOI: 10.1016/j.plabm.2024.e00362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Revised: 01/01/2024] [Accepted: 01/18/2024] [Indexed: 02/07/2024] Open
Abstract
Background Preeclampsia is a kind of pregnancy-related hypertension that affects 5.47 % of pregnancies in Ethiopia and 18.25 % of pregnant women who visit Arba Minch public health facilities for antenatal care. This study sought to identify hematological preeclampsia markers in pregnant women who received prenatal care at Arba Minch General Hospital. Methodology An institution-based comparative cross-sectional study was done from July 22 to October 30, 2021 at Arba Minch General Hospital. A total of 136 pregnant women were included in the study (46 with preeclampsia and 90 without preeclampsia). Epidata version 4.4. was used to enter data, and SPSS version 25.0 and Stata version17 were used for analysis. An independent sample t-test was used to examine the hematological parameter differences between study groups. Potential hematological markers were determined using receiver operating characteristic (ROC) analysis of the area under the curve (AUC). Statistical significance was defined if P value less than 0.05. Results A total of 136 pregnant women were studied. The complete blood count analysis showed that there were means differences in Red Cell Distribution (RDW) (p < 0.036), neutrophil-to-lymphocyte ratio (NLR) (p < 0.016) and relative lymphocyte count (Lymp%) (p < 0.047). The ROC analysis of the AUC for RDW, NLR and Lymp% resulted in 0.607, 0.609, 0.600 respectively. Conclusion RDW, NLR and Lymphocyte count could be potential candidate tools for the diagnosis and screening of preeclampsia. However, the robustness of the markers should be tested with prospective studies assessing changes present in each trimester.

Red blood cell distribution width (RDW) - A new nutritional biomarker to assess nutritional risk and response to nutritional therapy? Clin Nutr 2024; 43:575-585. [PMID: 38242035 DOI: 10.1016/j.clnu.2024.01.001] [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: 09/29/2023] [Revised: 12/29/2023] [Accepted: 01/02/2024] [Indexed: 01/21/2024]
Abstract
BACKGROUND & AIMS Red cell distribution width (RDW) has been proposed as a surrogate marker for acute and chronic diseases and may be influenced by nutritional deficits. We assessed the prognostic value of RDW regarding clinical outcomes and nutritional treatment response among medical inpatients at nutritional risk. METHODS This is a secondary analysis of EFFORT, a randomized, controlled, prospective, multicenter trial investigating the effects of nutritional support in patients at nutritional risk in eight Swiss hospitals. We examined the association between RDW and mortality in regression analysis. RESULTS Among 1,244 included patients (median age 75 years, 46.6 % female), high RDW (≥15 %) levels were found in 38 % of patients (n = 473) with a significant association of higher malnutrition risk [OR 1.48 (95%CI 1.1 to 1.98); p = 0.009]. Patients with high RDW had a more than doubling in short-term (30 days) mortality risk [adjusted HR 2.12 (95%CI 1.44 to 3.12); p < 0.001] and a signficant increase in long-term (5 years) mortality risk [adjusted HR 1.73 (95%CI 1.49 to 2.01); p < 0.001]. Among patients with high RDW, nutritional support reduced morality within 30 days [adjusted OR 0.56 (95%CI 0.33 to 0.96); p = 0.035], while the effect of the nutritional intervention in patients with low RDW was markedly smaller. CONCLUSIONS Among medical patients at nutritional risk, RDW correlated with several nutritional parameters and was a strong prognostic marker for adverse clinical outcomes at short- and long-term, respectively. Patients with high baseline RDW levels also showed a strong benefit from the nutritional intervention. Further research is needed to understand whether monitoring of RDW over time severs as a nutritional biomarker to assess effectiveness of nutritional treatment in the long run.

Evaluating circulating soluble markers of endothelial dysfunction and risk factors associated with PE: A multicentre longitudinal case control study in northern Ghana. Heliyon 2023; 9:e19096. [PMID: 37662780 PMCID: PMC10472241 DOI: 10.1016/j.heliyon.2023.e19096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 07/28/2023] [Accepted: 08/10/2023] [Indexed: 09/05/2023] Open
Abstract
Serpin E1/PAI-1, N-terminal pro-brain natriuretic peptide (NTpro-BNP) and neuropilin-1 are markers which have been associated with endothelial dysfunction. However, data on the levels of these markers in PE is limited. The limited data on the pathophysiology of PE in relation to these markers necessitated the study. This was a multicentre case-control study conducted at the Obstetrics and Gynaecology Department of the Tamale Teaching Hospital, the Bawku Presbyterian Hospital and the Bolgatanga Regional Hospital. Out of 520 consenting pregnant women, 127 pregnant women met the inclusion criteria (53 with PE and 74 controls) and were included in this study. Venous, placental, cord and peripheral blood were collected for biomarker assay, haematological parameters and placental parasite determination. Placental tissue sections were obtained for placental malaria and histopathological lesions associated with hypoperfusion. Maternal heart rate and foetal umbilical artery Doppler impedance indices; resistance index (RI) and systolic diastolic (SD) ratio were determined to confirm utero-placental hypoperfusion. Significantly higher proportions of foeto-maternal complications; eclampsia, low birth weight (LBW), neonatal intensive care unit admissions (NICU), intrauterine growth restriction (IUGR), caesarian deliveries and early gestational age at delivery were associated with PE. Women with PE had lower concentrations of platelet (p = 0.02) whereas red cell distribution width (RDW) was markedly elevated (p = 0.01). NTPro-BNP concentration was markedly elevated (p = 0.01) in women with PE whereas neuropilin-1 concentration was lower (p = 0.03) compared to the non-PE group. Maternal heart rate was elevated in women with PE and Doppler resistance indices (RI and SD) were significantly elevated in foetuses of PE women than foetuses of the controls. Placental mal-perfusion lesions were higher in women with PE compared to the non-PE group. Women with PE had increased risk of adverse foeto-maternal complications, significantly associated with placental mal-perfusion lesions, had reduced platelet concentration and elevated RDW-CV levels. NTPro-BNP, RI and SD are elevated in women with PE whereas neuropilin-1 concentration is reduced. Significant changes in these pathological variables in PE women is indicative of significant derangement in endothelial function culminating in adverse maternal and perinatal outcomes of pregnancy.

[PMID: 36103491 PMCID: PMC9473393 DOI: 10.1371/journal.pone.0274398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Accepted: 08/26/2022] [Indexed: 11/19/2022] Open
Abstract
Background
Preeclampsia (PE) is a pregnancy-specific disorder characterized by endothelial dysfunction, and activation of the coagulation system. Alteration of PLT parameters is the common hematological abnormality observed in women with PE. The main aim of this study was to systematically review previous studies from around the world to generate evidence about the relationship between platelet count (PC) and PE, as well as mean platelet volume (MPV) and PE, by calculating the pooled weighted mean difference (WMD) of PC and MPV between PE and normotensive (NT) groups.
Methods
Relevant articles which were published in the English language from January 10, 2011, to January 10, 2021, were systematically searched through PubMed, Web of Science, and African journals online. In addition, reference probing of published articles searching was employed through Google Scholar and Google for searching grey literature. The methodological qualities of articles were assessed using Joana Brigg’s institute critical appraisal checklist. A random-effects model was used to estimate pooled WMD of PLT parameters between the two groups with the respective 95% confidence intervals (CI) using Stata version 11.0. The I2 statistics and Egger’s regression test were used to assess heterogeneity and publication bias among included studies, respectively.
Results
A total of 25 articles were included in this systematic review and meta-analysis. Of which, 23 studies were used in each PC and MPV analysis. The overall pooled WMD of PC and MPV between PE and NT groups were -41.45 × 109/L [95% CI; -51.8, -31.0] and 0.98 fl [95% CI; 0.8, 1.1], respectively. The pooled WMD revealed that PC decreased significantly in the PE group compared to the NT group while MPV increased significantly in the PE group.
Conclusions
This systematic review and meta-analysis indicated that there is a significant decrease in PC and a significant increase in MPV during PE development among pregnant women. As a result, a change in these parameters among pregnant women may indicate the development of PE.

Abstract
Objective This prospective study was designed to develop and internally validate an accurate prognostic nomogram model with which to predict the adverse outcomes of preterm preeclampsia. Methods Pregnant women with preeclampsia were divided into the adverse outcome group and the no adverse outcome group. The Kaplan–Meier method, univariate Cox regression analysis, and calculation of the concordance index (C-index) were applied to predictive evaluation of the nomogram. Calibration curves were drawn to test the nomogram prediction and actual observation of the adverse outcome rate. Results After 1000 internal validations of bootstrap resampling, the C-index of the nomogram for predicting adverse outcomes within 48 hours was 0.74 and the cut-off value was 0.53, with a sensitivity of 61.57% and a specificity of 76.93%. The C-index of the nomogram for predicting adverse outcomes within 7 days was 0.76 and the cut-off value was 0.37, with a sensitivity of 58.17% and a specificity of 84.82%. The calibration curves showed good concordance of incidence of adverse outcomes between nomogram prediction and actual observation. Conclusion Cox regression has certain guiding significance in preventing and treating adverse outcomes, choosing the time of termination of pregnancy, and improving the prognosis of the mother and child.

[PMID: 33644193 PMCID: PMC7896688 DOI: 10.12998/wjcc.v9.i6.1259] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 12/16/2020] [Accepted: 01/05/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Indices such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), platelet distribution width (PDW), and red cell distribution width (RDW) are considered new markers of the systemic inflammatory response (SIR), and have been widely implemented for the diagnosis of patients with inflammatory diseases. These new indicators have also been widely investigated in preeclampsia (PE) but less analyzed in hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome.
AIM To compare SIR markers among HELLP patients, PE only patients, and healthy gravidae.
METHODS This retrospective case-control study enrolled 630 cases, including 210 patients with HELLP syndrome (HELLP group), 210 patients with only PE (PE group) and 210 healthy gravidae (control group). The three groups were matched by age, parity, status of assisted reproduction, and multiple pregnancies. Birthweight, gestational age at complete blood count collection, gestational age at delivery, mode of delivery, etc. were recorded. The main indices as NLR, PLR, MPV, PDW, and RDW among the groups were compared, as well as some secondary outcomes including neutrophil, platelets, and hemoglobin.
RESULTS The NLR (6.4 vs 4.3 vs 3.5), MPV (11.9 vs 11.2 vs 10.7), PDW (16.4 vs 13.3 vs 14.2), leukocyte (12.4 × 109/L vs 9.7 × 109/L vs 8.7 × 109/L) and neutrophil count (9.9 × 109/L vs 7.3 × 109/L vs 6.1 × 109/L) were highest in the HELLP group, lower in the PE group, and lowest in the control group. Both the overall comparisons between the three groups (all bP < 0.01) and pairwise comparisons between every two groups elicited statistically significant differences (all dP < 0.01, except control vs PE: cP < 0.05 in PDW). The average lymphocyte counts were 1.4 (1.1, 2.0) × 109/L in the HELLP group, 1.6 (1.3, 2.0) × 109/L in the PE group and 1.7 (1.4, 2.0) × 109/L in the control group. The overall comparison of lymphocyte count within the three groups had statistically significant differences (P = 0.000). The pairwise comparisons between every two groups demonstrated that the HELLP group had a lower lymphocyte count than both the PE (P = 0.019) and control groups (P = 0.000), but the difference between the PE and control groups was not statistically significant (P = 0.432). The overall comparisons on platelet counts and the PLR among these three groups also showed statistically significant differences (both P = 0.000), from low to high being those in the HELLP group (43.4 × 109/L, 64.0), control group (180.5 × 109/L, 103.6) and PE group (181.5 × 109/L, 112.8). Pairwise comparisons of neither index displayed statistically significant differences between the PE and control groups (both P > 0.05), while the differences in the two indices between the HELLP group and the two other groups were still statistically significant (all P = 0.000). RDW values were highest in the HELLP group (14.5% [13.6, 15.3]), lower in the control group (14.1% [13.5, 14.8]) and lowest in the PE group (13.9% [13.4, 14.9]). The difference between the PE and control group did not show statistical significance (P = 1.000), while RDW values in the HELLP group were higher than those in the other two groups (cP < 0.05 vs control, dP < 0.01 vs PE).
CONCLUSION SIR markers such as NLR, RDW, MPV, and PDW were increased and PLR was decreased in HELLP. These SIR markers may become new indicators in the evaluation of HELLP syndrome.

Pregnancy Hypertens 2020; 22:14-16. [PMID: 32693328 DOI: 10.1016/j.preghy.2020.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 07/08/2020] [Accepted: 07/11/2020] [Indexed: 10/23/2022]
Abstract
INTRODUCTION Preeclampsia (PE) is one of the most common causes of major maternal and fetal adverse events including mortality and preterm birth Grill et al. (2009). The neutrophil-to-lymphocyte ratio (NLR) and other hematologic indexes of systemic inflammation have been investigated in patients with PE for the prediction of the severity or presence of the disease. Despite these studies, we found no trials investigating the relationship between NLR and fetal outcomes in PE patients. In this study, we aimed to investigate the relationship between NLR and fetal outcomes. METHODS We retrospectively analyzed the demographic data and laboratory tests to determine the NLR of 175 pregnant women with severe PE admitted to our clinic between January 2015 and December 2018. RESULTS NLR in the first (2.4 ± 1.1 vs 2.9 ± 1.4, P = 0.18) and second trimesters (3.6 ± 0.7 vs 3.8 ± 1.3, P = 0.25) were not different between the groups, but third trimester NLR was significantly higher in patients with fetal loss (6.5 ± 5.4 vs 4.2 ± 2.7, P = 0.009). The area under the receiver operating characteristic curve for NLR in the third trimester was 0.66 and NLR > 3.9 predicted fetal loss with a sensitivity of 75% and a specificity of 61% (0.684, 95% confidence interval 0.48-0.83, P = 0.05). CONCLUSION We demonstrated that third trimester NLR is associated with fetal loss in patients with severe PE.

Abstract
PURPOSE Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), platelet distribution width (PDW), red cell distribution width (RDW), mean platelet volume (MPV), and plateletcrit (PCT) are known as systemic inflammatory response markers. In this study, we aimed to evaluate changes in NLR, PLR, PDW, RDW, MPV, and PCT in preeclampsia (PE) and their use in predicting its severity. MATERIALS AND METHODS This is a retrospective case-control study. The study comprised 64 control group (healthy pregnant females), 51 females with mild PE, and 13 with severe PE. These three groups were compared with demographic data and inflammation markers. RESULTS There were no statistically significant differences between healthy pregnant females and preeclaptic females in terms of median age, hemoglobin, lymphocyte, neutrophil, platelet, NLR, PLR, PDV, RDW, MPV, PCT (P > 0.05). The control group has a higher number of gravity and parity than the PE group (P < 0.001). MPV value is a lower PE group than the control group (P < 0.001). Both gravity and parity were significantly higher in the patients with mild PE than in the control group (P < 0.001). MPV value was statistically higher in the control group compared both mild and severe PE (P < 0.001), however, no statistical difference between mild and severe PE (P = 0.305). CONCLUSIONS MPV may be clinically useful markers in the prediction of PE. Further, prospective multicenter studies are needed to reveal the association between these markers and PE.

Abstract
BACKGROUND Preeclampsia is a serious pregnancy-related disease which may lead to adverse health effects to the mother and fetus. Besides many publications on the association of red cell distribution width (RDW) and preeclampsia, there has been no published meta-analysis. This necessitated the present systemic review and met-analysis to assess the RDW in relation to preeclampsia. METHODS Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed. Relevant published studies were searched in PubMed, Cochrane library, Google scholar, Scopus, Embase and CINAHL using the term "Preeclampsia OR eclampsia AND red cell distribution width OR red blood cells). Modified Newcastle - Ottawa quality assessment scale was used for critical appraisal of retrieved studies. Pooled Meta logistic regression was computed using OpenMeta Analyst software. Subgroup and meta-regression methods were performed to analyse the heterogeneity. RESULTS Eleven case control studies were included in the met-analyses with a total of 951 cases (preeclampsia) and 2024 controls. The mean (SD) of the RDW level was significantly higher in women with preeclampsia compared to controls [15.10 (2.48) % vs. 14.26(1.71) %, P < 0.001]. The mean difference was 0.85, 95% CI = 0.26-1.43. Due to a high heterogeneity (I2 = 90.45, P < 0.001), the continuous random effect model was used.Eight studies compared RDW level in the mild (N = 360) with severe cases (N = 354) of preeclampsia. The RDW level was significantly higher in women with severe preeclampsia compared to those with mild preeclampsia [15.37 (2.48) % vs. 14.037(1.79) %, P < 0.001]. The mean difference was 1.07, 95% CI = 0.45-1.70. Since there is a high heterogeneity [I2 = 76.67, P < 0.001], the continuous random effect model was used.Through the met-regression model, except for the region of the study (P < 0.001), none of investigated variables (age, parity, quality of the study) was significantly associated with the investigated heterogeneity. The outliers (3studies) were removed to reduce the heterogeneity. The pooled meta-analysis of the remaining 8 studies showed a significant difference in the RDW between preeclamptic women compared with the controls. The mean difference was 0.93, 95% CI = 0.56-1.31, P < 0.001. Because of heterogeneity [I2 = 69.6, P = 0.002], the continuous random effect model was used. CONCLUSION RDW level was significantly higher in women with preeclampsia compared to controls. Similarly, women with severe preeclampsia had significantly higher RDW than those with the mild form.

Abstract
Objective This study aimed to compare the first trimester complete blood count (CBC) indices of pregnancies complicated by early-onset preeclampsia (EOPE) or late-onset preeclampsia (LOPE). Material and Methods A retrospective case-control study was conducted with 186 patients. Patients were classified into three subgroups: EOPE, LOPE, and control groups. First trimester CBC results were obtained for each patient. Hemoglobin, hematocrit, red blood cell distribution width, mean corpuscular volume, white blood cell (WBC) count, neutrophil, eosinophil, basophil, lymphocyte, monocyte, mean platelet volume, platelet distribution width, plateletcrit, and platelet count were compared. The neutrophil lymphocyte ratio was calculated by dividing the absolute lymphocyte count by the absolute neutrophil count. The platelet lymphocyte ratio was calculated by dividing the absolute lymphocyte count by the absolute platelet count. Results The total number of cases was 21, 42, and 123, in the EOPE, LOPE, and control groups, respectively. There were statistically significant differences in the total WBC and neutrophil counts between the three groups (both p<0.05). WBC and neutrophil counts were found to be highest in the EOPE group, and the LOPE group had higher levels compared with controls. The optimal cut-off values to predict EOPE for WBC and neutrophil counts were 9.55×103/ μL (sensitivity 71.4% and specificity 70.7%) and 6.45×103/μL (sensitivity 66.7% and specificity 74.8%), respectively. Conclusion Increased first trimester WBC and neutrophil counts may be predictive for EOPE.

Abstract
Anisocytosis has been associated with the severity and prognosis of several acute and chronic diseases, as well as physiological conditions such as pregnancy. Anisocytosis is quantified by the red blood cell distribution width (RDW), expressed as the ratio, multiplied by 100, between the standard deviation (SD) of red blood cell volumes and the mean corpuscular volume, or as the SD of erythrocyte volumes (RDW-SD). The aim of the present review was to report the state of the art on the physiological values and the putative diagnostic and prognostic roles of RDW in complicated pregnancy. Literature research for articles published in the last ten years was conducted in Pubmed, Web of Science, ClinicalTrials.gov, and Scopus databases. Abstracts were independently screened by two investigators. If relevant, full articles were retrieved. References, in these articles, citing relevant reviews or original studies were also accessed to identify additional eligible studies. Any disagreement between the reviewers was resolved by a third investigator. A total of 28 studies were included in the review. These studies reported changes in RDW values during physiological pregnancy, and associations between the RDW and several pregnancy complications including anaemia, preeclampsia, gestational diabetes, and recurrent miscarriage. This review provides background information for establishing physiological and pathological RDW values in pregnancy for diagnostic and prognostic use in clinical practice.

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.

Abstract
OBJECTIVE Ectopic pregnancy (EP) is the major cause of maternal morbidity and mortalityinthe first trimester of pregnancy. EP can be treated either medical or surgical approches. The purpose of our study wasto predict the treatment choice of tubal EP by usinghematologic parameters which are routinely used in clinical practice. METHODS After retrospectively data evaluation was done from Januaryu 2014 to Deceber 201. we had 153 patients with EP. Patientsadmitted to methotrexate (MTX) therapy was Group-1. Patients performed surgerywas Group-II. All patients' initial values including white blood cell (WBC), hemoglobin (Hgb), mean corpuscular volume (MCV), neutrophil and lymphocyte, neutrophil lymphocyte ratio (NLR), platelet, platelet lymphocyte ratio (PLR), red cell distribution width (RDW), platelet distribution width (PDW) and mean platelet volume (MPV)were recorded and compared between groups. RESULTS Of 153 EP patients, there were 93 patients in MTX group and 60 patients in surgery group. RDW, MPV were significantly increased in MTX group (p=0.003, p=0.001, p=0.038, respectively). However, no statistically significant difference was observed between the groups in terms of WBC, Hgb, MCV, PLT, PLR, PDW. CONSLUSION RDW, MPV values were independently associated with MTX therapy. Hematologic parameters can be helpful in the choice of the EP treatment.

Abstract
INTRODUCTION AND AIM Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), red cell distribution width (RDW) and plateletcrit (PCT) have all been recognized as systemic inflammatory response (SIR) markers. Our aim was to evaluate changes in NLR, PLR, RDW, MPV and PCT in preeclampsia and their use in predicting the severity of PE. STUDY DESIGN This retrospective cohort study included 219 patients. Of them, 27 had mild PE, 82 had severe PE, and 110 were healthy, normotensive pregnant patients. RESULTS There were no significant differences in NLR between the groups (p=0.423). Both PLR and PCT were lower in the patients with severe PE than in the control group, and these differences showed a statistical significance (p=0.007 and p<0.001). On the other hand, both RDW and MPV were statistically higher in the patients with severe PE compared to the control group (p=0.011 and p<0.001). ROC analyzes were used to examine the ability of markers to predict those with severe PE from those with mild PE. Areas under the curve for NLR, PLR and RDW were not statistically significant (p=0.636, 0.104 and 0.36, respectively). For MPV and PCT, the values of area under the curve were 0.641 and 0.712, respectively, and the p values for these parameters statistically differed (p=0.028, p=0.001). CONCLUSION MPV or PCT may be clinical useful markers in the prediction of severe PE. Further, prospective multicenter studies are warranted to better reveal the association between SIR markers and PE.

Abstract
OBJECTIVE Preeclampsia is a serious disease and a leading cause of maternal and perinatal mortality and morbidity. Red blood cell distribution width (RDW), a measure of anisocytosis, is used as an inflammation marker in hypertension and cardiovascular diseases. Although the relationship between RDW and hypertension has been well documented, the association between preeclampsia and RDW is not clear. We aimed to investigate the relationship between RDW and preeclampsia and its severity. MATERIALS AND METHODS One hundred eighteen pregnant women with preeclampsia and one hundred twenty uncomplicated pregnant women were included in the study. Blood samples for routine CBC and RDW levels were analyzed. RESULTS The RDW values were significantly higher in preeclampsia group compared with the control group (15.23±1.96 vs 14.48±1.70, p<0.05). We also confirmed that RDW levels were significantly higher in severe preeclampsia group than mild preeclampsia group in subgroup analyses (15.08±2.07, 15.92±1.99, p<0.05). CONCLUSION Our study showed that there is an association between RDW and preeclampsia and also its severity. RDW, a marker which is easy, inexpensive and calculated as a part of blood cell count, can be used as a significant diagnostic and prognostic marker in patient with preeclampsia like the other cardiovascular diseases.

Abstract
Preeclampsia (PE) is a complex, multisystem disorder that remains a leading cause of morbidity and mortality in pregnancy. Four main classes of dysregulation accompany PE and are widely considered to contribute to its severity. These are abnormal trophoblast invasion of the placenta, anti-angiogenic responses, oxidative stress, and inflammation. What is lacking, however, is an explanation of how these themselves are caused. We here develop the unifying idea, and the considerable evidence for it, that the originating cause of PE (and of the four classes of dysregulation) is, in fact, microbial infection, that most such microbes are dormant and hence resist detection by conventional (replication-dependent) microbiology, and that by occasional resuscitation and growth it is they that are responsible for all the observable sequelae, including the continuing, chronic inflammation. In particular, bacterial products such as lipopolysaccharide (LPS), also known as endotoxin, are well known as highly inflammagenic and stimulate an innate (and possibly trained) immune response that exacerbates the inflammation further. The known need of microbes for free iron can explain the iron dysregulation that accompanies PE. We describe the main routes of infection (gut, oral, and urinary tract infection) and the regularly observed presence of microbes in placental and other tissues in PE. Every known proteomic biomarker of "preeclampsia" that we assessed has, in fact, also been shown to be raised in response to infection. An infectious component to PE fulfills the Bradford Hill criteria for ascribing a disease to an environmental cause and suggests a number of treatments, some of which have, in fact, been shown to be successful. PE was classically referred to as endotoxemia or toxemia of pregnancy, and it is ironic that it seems that LPS and other microbial endotoxins really are involved. Overall, the recognition of an infectious component in the etiology of PE mirrors that for ulcers and other diseases that were previously considered to lack one.

Abstract
BACKGROUND The red blood cell distribution width (RDW) is a rather simple measure of red blood cell (RBC) size heterogeneity (i.e., anisocytosis), which is easily calculated by dividing the standard deviation (SD) of erythrocyte volumes for the mean corpuscular volume (MCV). Emerging evidence suggests that, besides RBC abnormalities, many human disorders may be frequently associated with a high degree of anisocytosis. METHODS In this narrative review, we analyzed the current scientific literature about the putative role and the potential epidemiologic association between RDW and cardiovascular diseases. The findings of the most representative epidemiological studies were summarized and discussed. RESULTS Overall, considerable and convincing evidence has been brought that an increased RDW value is associated with acute coronary syndrome (ACS) [including acute myocardial infarction (AMI)], ischemic cerebrovascular disease (including stroke), peripheral artery disease (PAD), as well as with atrial fibrillation (AF), heart failure (HF) and hypertension. Higher anisocytosis also significantly and independently predicts adverse outcomes in patients with these conditions. CONCLUSIONS Although the role of anisocytosis in the pathogenesis of cardiovascular diseases remains uncertain, the considerable evidence available so far suggests that the clinical use of RDW may be broadened beyond the conventional boundaries of erythrocyte disorders, in particular for assisting the diagnosis and prognostication of patients with ACS, ischemic cerebrovascular disease, PAD, HF and AF.

Abstract
BACKGROUND Preeclampsia is a leading cause of maternal and perinatal mortality worldwide. The exact etiology of preeclampsia is unknown, but the inflammatory process is postulated as one of the etiologies. Red blood cell distribution width (RDW) is a measure of anisocytosis (variation of red cell size) and is associated with hypertension and diabetic ketoacidosis. There are few data on the association between RDW and preeclampsia. This study aimed to investigate the association between RDW and preeclampsia. METHODS A case-control study was conducted at Khartoum Hospital, Sudan, during June to August 2012. Cases were women with preeclampsia and healthy women were controls. Sociodemographic characteristics, obstetrics, and clinical data were recorded. The complete blood count, including RDW, was measured using an automated hematology analyzer. RESULTS The cases and controls (65 women in each arm) were matched in their basic characteristics. There was no difference in the mean (SD) RDW between women with preeclampsia and controls (14.5 ± 1.8% vs. 14.4 ± 1.4%, P = 0.710). There was also no difference in the mean RDW between women with mild and severe preeclampsia (14.7 ± 1.9% vs. 13.9 ± 1.4%, P = 0.144. In logistic regression, there was no association between RDW and preeclampsia (OR = 0.9, CI = 0.7-1.1, P = 0.952). CONCLUSIONS RDW levels are not associated with the presence or severity of preeclampsia.
