Abstract
Aging is interrelated with changes in red blood cell parameters and functionality. In this article, we focus on red blood cells (RBCs) and provide a review of the known changes associated with the characterization of RBC deformability in aging and related pathologies. The biophysical parameters complement the commonly used biochemical parameters and may contribute to a better understanding of the aging process. The power of the deformability measurement approach is well established in clinical settings. Measuring RBCs' deformability has the advantage of relative simplicity, and it reflects the complex effects developing in erythrocytes during aging. However, aging and related pathological conditions also promote heterogeneity of RBC features and have a certain impact on the variance in erythrocyte cell properties. The possible applications of deformability as an early biophysical biomarker of pathological states are discussed, and modulating PIEZO1 as a therapeutic target is suggested. The changes in RBCs' shape can serve as a proxy for deformability evaluation, leveraging single-cell analysis with imaging flow cytometry and artificial intelligence algorithms. The characterization of biophysical parameters of RBCs is in progress in humans and will provide a better understanding of the complex dynamics of aging.

Abstract
Red cell distribution width (RDW) is an easy-to-access marker which is routinely measured in complete blood count (CBC) test. Besides the classic use of RDW as a marker for discriminating different types of anemia, recent studies had indicated the relationship between high RDW and cardiovascular diseases. High RDW is not only useful in the diagnosis and prognostication of various cardiovascular conditions but also could be used as a valuable tool for predicting the incidence of cardiovascular diseases. population-based studies have indicated that higher RDW could effectively predict the incidence of heart failure (HF), atherosclerotic diseases, and atrial fibrillation (AF). It has been also demonstrated that higher RDW is associated with worse outcomes in these diseases. Recent studies have shown that high RDW is also associated with other cardiovascular conditions including cardiomyopathies, and pulmonary hypertension. The predictive role of RDW in endovascular interventions has also been demonstrated by many recent studies. Here in this review, we attempt to compile the most recent findings with older reports regarding the relation between high RDW and HF, cardiomyopathies, pulmonary hypertension, AF, atherosclerotic disorders, primary hypertension, and the outcomes of endovascular interventions. we also discussed the role of RDW in the prognostication of different cardiovascular conditions when combined with classic classification criteria.

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.

Abstract
The existing data have shown inconsistency about the association between red cell distribution width (RDW) and hypertension. Thus, the aim of the present study was to investigate the association between RDW and newly diagnosed hypertension among adults in Sudan. This was a case-control study conducted in Northern Sudan from July to September 2022. The cases were patients with newly diagnosed hypertension (n = 78), and the controls were healthy participants (n = 78). A questionnaire was used to collect the participants' sociodemographic, and clinical data. RDW was measured using an automated hematology analyzer. A logistic regression analysis was performed. The univariate analysis revealed no association between sex, educational level, occupational level, RDW, and newly diagnosed hypertension. In the multivariate analysis, increasing age (adjusted odds ratio [AOR], 1.05; 95% confidence interval [CI], 1.02‒1.08) and body mass index (AOR, 1.12; 95% CI, 1.05‒1.19) were associated with newly diagnosed hypertension. No association was found between RDW and newly diagnosed hypertension. No correlation was found between RDW and systolic (r = 0.045, P = 0.577) or diastolic blood pressure (r = 0.023, P = 0.772). In conclusion, no association in RDW was found between the patients with newly diagnosed hypertension and the healthy controls.

Abstract
Hypertension (HT) is a common chronic disease that often causes target-organ damage and severe complications, contributing to cardiovascular morbidity and mortality worldwide. Accumulating evidence suggests that inflammation plays a prominent role in the initiation and progression of HT. Multiple inflammatory biomarkers have been proposed to predict HT. Several new hematological parameters can reflect the inflammatory response and platelet activation. The major advantage of hematological parameters over conventional inflammatory markers is that they are relatively inexpensive and easily obtained from routine blood tests. Numerous studies have investigated several hematological parameters for their utility as predictive biomarkers for the diagnosis and prognosis of HT. Among them, the neutrophil to lymphocyte ratio (NLR), monocyte to high density lipoprotein cholesterol ratio (MHR), red cell distribution width (RDW), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), platelet distribution width (PDW), and systemic immune-inflammation index (SII) have recently received attention. We searched PubMed and Embase databases (up to September 18, 2022) to assess the relationships between hematological parameters and HT. This review discusses the diagnostic and prognostic value of these hematological parameters in HT, providing an important basis for early screening, risk stratification, and optimal management of hypertensive patients.

Abstract
BACKGROUND Hypertension is a prevalent cardiovascular disease with severe longer-term implications. Conventional management based on clinical guidelines does not facilitate personalized treatment that accounts for a richer set of patient characteristics. METHODS Records from 1/1/2012 to 1/1/2020 at the Boston Medical Center were used, selecting patients with either a hypertension diagnosis or meeting diagnostic criteria (≥ 130 mmHg systolic or ≥ 90 mmHg diastolic, n = 42,752). Models were developed to recommend a class of antihypertensive medications for each patient based on their characteristics. Regression immunized against outliers was combined with a nearest neighbor approach to associate with each patient an affinity group of other patients. This group was then used to make predictions of future Systolic Blood Pressure (SBP) under each prescription type. For each patient, we leveraged these predictions to select the class of medication that minimized their future predicted SBP. RESULTS The proposed model, built with a distributionally robust learning procedure, leads to a reduction of 14.28 mmHg in SBP, on average. This reduction is 70.30% larger than the reduction achieved by the standard-of-care and 7.08% better than the corresponding reduction achieved by the 2nd best model which uses ordinary least squares regression. All derived models outperform following the previous prescription or the current ground truth prescription in the record. We randomly sampled and manually reviewed 350 patient records; 87.71% of these model-generated prescription recommendations passed a sanity check by clinicians. CONCLUSION Our data-driven approach for personalized hypertension treatment yielded significant improvement compared to the standard-of-care. The model implied potential benefits of computationally deprescribing and can support situations with clinical equipoise.

Abstract
AIM Left ventricular hypertrophy (LVH) is one of the most common types of target organ damage in hypertension. The red blood cell distribution width (RDW) is closely related to many cardiovascular diseases, including hypertension. The aim of this study was to analyze the relationship between the RDW level and LVH in pediatric essential hypertension. MATERIALS AND METHODS A total of 429 untreated children and adolescents with essential hypertension were recruited and divided into an LVH group (n = 114) and non-LVH group (n = 315) according to left ventricular mass index (LVMI) and relative wall thickness (RWT) by color Doppler ultrasound. Spearman correlation analysis was used to determine the relationship between RDW and LVMI, RWT. The effect of RDW on LVH was determined using a multivariate logistic regression analysis. To assess the predictive value of RDW on LVH, the receiver operating characteristic (ROC) curve was used. RESULTS The level of RDW in children with hypertension in the LVH group was significantly higher than that in the non-LVH group (13.0 [12.0, 13.0] vs. 12.4 [12.0, 13.0] %, P = 0.001). The incidence of low and high quantiles of LVH was 21.0% and 32.0%, respectively. Spearman correlation analysis showed that RDW was positively correlated with C-reactive protein (CRP), LVMI, RWT, and red blood cell (RBC) count (P all < 0.05), and negatively correlated with hemoglobin (HGB) level, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) (P all < 0.05). After adjusting for various confounding factors, a multivariate logistic regression model revealed that RDW was an independent risk factor for LVH (OR = 1.946, 95% CI: 1.324-2.861, P = 0.001). The area under the ROC curve of RDW predicting centripetal hypertrophy was 0.700 (95% CI: 0.541-0.859, P < 0.05) in pediatric essential hypertension. CONCLUSIONS Increased RDW levels are an independent risk factor for LVH in pediatric essential hypertension, and RDW may be a predictor of LVH in untreated pediatric essential hypertension.

Abstract
We describe methodology for joint reconstruction of physiological-survival networks from observational data capable of identifying key survival-associated variables, inferring a minimal physiological network structure, and bridging this network to the Gompertzian survival layer. Using synthetic network structures, we show that the method is capable of identifying aging variables in cohorts as small as 5,000 participants. Applying the methodology to the observational human cohort, we find that interleukin-6, vascular calcification, and red-blood distribution width are strong predictors of baseline fitness. More important, we find that red blood cell counts, kidney function, and phosphate level are directly linked to the Gompertzian aging rate. Our model therefore enables discovery of processes directly linked to the aging rate of our species. We further show that this epidemiological framework can be applied as a causal inference engine to simulate the effects of interventions on physiology and longevity.

Abstract
Background Among the problems caused by hypertension, early renal damage is often ignored. It can not be diagnosed until the condition is severe and irreversible damage occurs. So we decided to screen and explore related risk factors for hypertensive patients with early renal damage and establish the early-warning model of renal damage based on the data-mining method to achieve an early diagnosis for hypertensive patients with renal damage. Methods With the aid of an electronic information management system for hypertensive out-patients, we collected 513 cases of original, untreated hypertensive patients. We recorded their demographic data, ambulatory blood pressure parameters, blood routine index, and blood biochemical index to establish the clinical database. Then we screen risk factors for early renal damage through feature engineering and use Random Forest, Extra-Trees, and XGBoost to build an early-warning model, respectively. Finally, we build a new model by model fusion based on the Stacking strategy. We use cross-validation to evaluate the stability and reliability of each model to determine the best risk assessment model. Results According to the degree of importance, the descending order of features selected by feature engineering is the drop rate of systolic blood pressure at night, the red blood cell distribution width, blood pressure circadian rhythm, the average diastolic blood pressure at daytime, body surface area, smoking, age, and HDL. The average precision of the two-dimensional fusion model with full features based on the Stacking strategy is 0.89685, and selected features are 0.93824, which is greatly improved. Conclusions Through feature engineering and risk factor analysis, we select the drop rate of systolic blood pressure at night, the red blood cell distribution width, blood pressure circadian rhythm, and the average diastolic blood pressure at daytime as early-warning factors of early renal damage in patients with hypertension. On this basis, the two-dimensional fusion model based on the Stacking strategy has a better effect than the single model, which can be used for risk assessment of early renal damage in hypertensive patients.

Abstract
Red blood cell distribution width (RDW) is a measure of the change in size of red blood cells and it is used in combination with other hematological parameters for the differential diagnosis of anemias. Recent evidence suggested that the change in RDW level may be a predictive biomarker of morbidity and mortality in cardiovascular diseases (CVDs). Cardiovascular diseases are the most common cause of death globally as compared to cancer and communicable diseases. Early diagnosis and prompt intervention of these diseases are very important to minimize their complications. Nowadays, the diagnosis of most cardiovascular diseases majorly depends on clinical judgment, electrocardiography and biochemical parameters. Red blood cell distribution width as a new predictive biomarker may play a pivotal role in assessing the severity and progression of CVDs. However, the underlying mechanisms for the association between RDW and CVDs are not clear. A deeper understanding of their association could help the physicians in more careful identification, early prevention, intervention, and treatment to prevent adverse cardiovascular events. This review aims to elaborate on the recent knowledge on the association between RDW and cardiovascular diseases and some possible pathophysiological mechanisms.

Abstract
Childhood hypertension has become a global public health issue due to its increasing prevalence and association with cerebral‐cardiovascular disease in adults. In this study, we developed a predictive model for childhood hypertension based on environmental and genetic factors to identify at‐risk individuals. Eighty children diagnosed with childhood hypertension and 84 children in the control group matched by sex and age from an established cohort were included in a nested case–control study. We constructed a multiple logistic regression model to analyze the factors associated with hypertension and applied the 10‐fold cross‐validation method to verify the prediction stability of the model. Childhood hypertension was found positively correlated with triglyceride level ≥150 mg/dL; low‐density lipoprotein cholesterol level ≥110 mg/dL; body mass index Z score; waist‐to‐height ratio Z score; and red blood cell count (all P < .01) and negatively correlated with the relative expression level of retinol acyltransferase; relative expression level of vitamin D receptor; and dietary intake of fiber, vitamin C and copper (all P < .05) in this study. BMI Z score, triglyceride ≥150 mg/dL, RBC count, VDR/β‐actin and LRAT/β‐actin ratios were used to construct the predictive model. The area under the receiver operating characteristic curve was 94.45% (95% CI = 89.35%∼98.65%, P < .001). The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were all above 80% in both the training and validation sets. In conclusion, this model can predict the risk of childhood hypertension and could provide a theoretical basis for early prevention and intervention to improve the cardiovascular health of children.

Abstract
BACKGROUND Red cell distribution width (RDW) and the systemic immune-inflammation index (SII) have been extensively studied as predictors of morbidity and mortality in several cardiovascular diseases. This prospective study aimed to investigate the relationship between long term major adverse cardiac events (MACEs) and simple hematological parameters in hypertensive patients. METHODS The study included a total of 1202 patients with newly diagnosed HT. Of the patients, 662 (55.1%) were female and 540 (44.9%) were male, with a mean age of 53.0 ± 11.4 years. The primary endpoint of the study was long term MACE, including cardiac death, stroke, and myocardial infarction. This is the first study focusing on the association of SII with major adverse cardiovascular outcomes in patients with HT. RESULTS Eighty-nine patients (8.7%) developed at least one MACE during a mean follow-up period of 82.2 ± 1.3 months. RDW (13.0 ± 0.9 vs. 13.5 ± 1.2%, p < .001) and SII [465.0 (353.4-609.4) vs. 584.4 (468.9-794.0) x103/µL, p < .001] were significantly higher in patients with MACEs. The prevalence of MACEs was significantly higher in patients with RDW>13.1% (10.4 vs. 5%; p < .001) and in patients with SII>465 x103/µL (11.8 vs. 3.1%; p < .001). The multivariate logistic regression analysis showed SII and RDW were independent predictors of MACEs. CONCLUSION The results of the study demonstrated that the RDW and SII were independent predictors of long-term cardiovascular events in hypertensive patients. These simple hematological parameters may be used as prognosticators of MACE in patients with newly diagnosed HT.

Abstract
BACKGROUND Hypertension is the major public health concern; leading to cardiovascular disease. It is associated with alteration in hematological parameters which may lead to end-organ damage. Thus, this study aimed to compare hematological parameters between hypertensive and normotensive adult groups in Harar, eastern Ethiopia. METHODS A comparative cross-sectional study was conducted from January to March, 2020 at Jugel and Hiwotfana Specialized University hospital, Harar, eastern Ethiopia. Convenient sampling technique was used to recruit 102 hypertensive patients from the two hospitals and 102 apparently healthy blood donors. Participant's socio-demographic and clinical information were collected using pre-tested structured questionnaire. Blood sample were collected and analyzed by Beckman Coulter DxH 500 analyzer for complete blood count. The data were entered and analyzed using SPSS version 23. Independent t-test and Mann Whitney u-test was used for comparison between groups. Spearman's correlation was used for correlation test. P values less than 0.05 was considered as statistically significant. RESULT 102 hypertensive and 102 healthy controls were enrolled in this study. The median ± IQR value of white blood cell (WBC) count, hemoglobin (Hgb), hematocrit (HCT), red cell distribution width (RDW) and mean platelet volume (MPV) were significantly higher in hypertensive group compared to apparently healthy control group. Additionally, RBC (red blood cell) count, HCT and RDW showed statistically significant positive correlations with systolic and diastolic blood pressure. WBC count and RDW were significantly and positively correlated with body mass index (BMI). Platelet (PLT) count had a significant but negative correlation (r = -0.219, P = 0.027) with duration of hypertension illness while MPV showed positive and significant correlation (r = 0.255, P = 0.010). CONCLUSION The median values of WBC, Hgb, HCT, RDW and MPV were significantly higher in hypertensive patient compared to apparently healthy individuals. Hence, it is important to assess hematological parameters for hypertensive individuals which may help to prevent complications associated with hematological aberrations. However, further studies are required to understand hypertensive associated changes in hematological parameters.

Red blood cell distribution width as a novel prognostic marker after myocardial revascularization or cardiac valve surgery. Sci Rep 2021; 11:7889. [PMID: 33846483 PMCID: PMC8041885 DOI: 10.1038/s41598-021-87075-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 02/02/2021] [Indexed: 01/12/2023] Open
Abstract
The red blood cell distribution width (RDW) measures the variability in the size of circulating erythrocytes. Previous studies suggested a powerful correlation between RDW obtained from a standard complete blood count and cardiovascular diseases in both primary and secondary cardiovascular prevention. The current study aimed to evaluate the prognostic role of RDW in patients undergoing cardiac rehabilitation after myocardial revascularization and/or cardiac valve surgery. The study included 1.031 patients with available RDW levels, prospectively followed for a mean of 4.5 ± 3.5 years. The mean age was 68 ± 12 years, the mean RDW was 14.7 ± 1.8%; 492 patients (48%) underwent cardiac rehabilitation after myocardial revascularization, 371 (36%) after cardiac valve surgery, 102 (10%) after valve-plus-coronary artery by-pass graft surgery, 66 (6%) for other indications. Kaplan–Meier analysis and Cox hazard analysis were used to associate RDW with mortality. Kaplan–Meier analysis demonstrated worse survival curves free from overall (log-rank p < 0.0001) and cardiovascular (log-rank p < 0.0001) mortality in the highest RDW tertile. Cox analysis showed RDW levels correlated significantly with the probability of overall (HR 1.26; 95% CI 1.19–1.32; p < 0.001) and cardiovascular (HR 1.31; 95% CI 1.23–1.40; p < 0.001) mortality. After multiple adjustments for cardiovascular risk factors, hemoglobin, hematocrit, C-reactive protein, microalbuminuria, atrial fibrillation, glomerular filtration rate,left ventricular ejection fraction and number of exercise training sessions attended, the increased risk of overall (HR 1.10; 95% CI 1.01–1.27; p = 0.039) and cardiovascular (HR 1.13; 95% CI 1.01–1.34; p = 0.036)mortality with increasing RDW values remained significant. The RDW represents an independent predictor of overall and cardiovascular mortality in secondary cardiovascular prevention patients undergoing cardiac rehabilitation.

Abstract
Arterial hypertension represents one of the most common pathologies in the adult population. Hypertensive patients have structurally altered arteries, with a higher rigidity that leads to a significant decrease in vascular compliance. At the base of the pathophysiological process stands the inflammation, as a reaction of the organism to injury. OBJECTIVES This study aims to highlight clinical-paraclinical correlations in people diagnosed with arterial hypertension and inflammatory status. Thus, we would like to evaluate possible correlations between the usual inflammatory markers and blood pressure values. MATERIALS AND METHODS The sample comprises 64 adults who were subsequently divided based on the diagnosis of arterial hypertension, by using Automatic Blood Pressure Monitoring, as following: Study group=26 patients (with arterial hypertension) and Control group: 38 patients (without arterial hypertension). RESULTS The study has revealed negative correlations between the neutrophil/lymphocyte ratio (NLR) and the general diastolic average (r=-0.248 and p=0.047), the diurnal diastolic average (r=-0.258 and p=0.038) and the diurnal mean arterial pressure (r=-0.249 and p=0.046) and a negative correlation between the red cell distribution width (RDW) and the dipping index (r=-0.402 and p=0.013), each of them accomplishing the level of statistical significance. CONCLUSIONS NLR can be used as a predictor of diastolic blood pressure values and as a factor of prognosis for the evolution of arterial hypertension. RDW is higher in non-dipping patients.

Risk Factors for Acute Coronary Syndrome in Upper Gastrointestinal Bleeding Patients. Gastroenterol Res Pract 2021; 2021:8816805. [PMID: 33763128 PMCID: PMC7964100 DOI: 10.1155/2021/8816805] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 01/23/2021] [Accepted: 02/05/2021] [Indexed: 12/20/2022] Open
Abstract
Background Upper gastrointestinal bleeding (UGIB) is a common critical disease with a certain fatality rate. Acute coronary syndrome (ACS), another critical ill condition, is a regular occurrence in the UGIB. We identified risk factors for ACS in UGIB. Methods 676 patients diagnosed with UGIB were enrolled retrospectively. We assessed the occurrence of ACS in UGIB patients and identified the risk factors for ACS by logistic regression analysis and random forest analysis. Results After propensity score matching (PSM), the ACS group (n = 69) and non-ACS group (n = 276) were analyzed. Logistic regression analysis showed that syncope (P = 0.001), coronary heart disease history (P = 0.001), Glasgow Blatchford score (P ≤ 0.001), Rockall risk score (P = 0.004), red blood cell distribution width (RDW) (P ≤ 0.001), total bilirubin (TBil) (P = 0.046), fibrinogen (P ≤ 0.001), and hemoglobin (P = 0.001) had important roles in ACS patients. With Mean Decrease Gini (MDG) sequencing, fibrinogen, RDW, and hemoglobin were ranked the top three risk factors associated with ACS. In ROC analysis, fibrinogen (AUC = 0.841, 95% CI: 0.779-0.903) and RDW (AUC = 0.826, 95% CI: 0.769-0.883) obtained good discrimination performance. According to sensitivity > 80%, the pAUC of fibrinogen and RDW were 0.077 and 0.101, respectively, and there was no significant difference (P = 0.326). However, according to specificity > 80%, the pAUC of fibrinogen was higher than that of RDW (0.126 vs. 0.088, P = 0.018). Conclusion Fibrinogen and RDW were important risk factors for ACS in UGIB. Additionally, combination with coronary heart disease, syncope, hemoglobin, and TBil played important roles in the occurrence of ACS. Meanwhile, it was also noted that Rockall score and Glasgow Blatchford score should be performed to predict the risk.

Abstract
PURPOSE Erectile dysfunction (ED) has increased prevalence by age and significantly affects the quality of life of men and their partners. To investigate the relationship between ED and red blood cell distribution width (RDW) values. MATERIALS AND METHOD Between September 2019 and December 2019, a total of 192 individuals comprising those that were admitted to the urology outpatient clinic with ED complaints and healthy volunteers from among hospital staff were prospectively included in the study. The participants were divided into two groups according to the international erectile function index (IIEF-5) as ED group (n=148) and control group (n=44). RESULTS There was no statistically significant difference between the two groups in terms of age, smoking status, presence of hypertension, triglyceride, low-density lipoprotein, high-density lipoprotein, total cholesterol, total prostate-specific antigen and haematocrit values. Body mass index, fasting blood sugar, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were significantly higher in the ED group (28.5±27.4kg/m2 vs 26.8±26.5kg/m2, p=.021, 109.05±49.7mg/dl vs 93.39±10.2mg/dl, p<.001, 2.18±1.3 vs 1.74±0.3, p=.031, and 113.7±47 vs 92.4±24.1, p=.004, respectively). The mean RDW values were 13.7±1.1 in the ED group and 13±0.5 in the control group (p<.001). The multivariate analysis revealed PLR [1.02 OR (1-1.04), p=.007] and RDW [2.75 OR (1.56-4.85), p<.001] as independent predictors for an ED diagnosis. CONCLUSION Based on the strong relationship between RDW and ED, we consider that RDW may be a new indicator in the diagnosis of ED.

Abstract
OBJECTIVE To investigate the risk factors for orthostatic hypertension in children. STUDY DESIGN Eighty children with orthostatic hypertension were enrolled in the group with orthostatic hypertension, and 51 healthy children served as the control group. Demographic characteristics, clinical history, daily water intake, nightly sleep duration, the results of the standing test, and complete blood count were recorded and compared between the 2 groups. The risk factors for pediatric orthostatic hypertension were determined by logistic regression analysis. RESULTS Body mass index and red blood cell distribution width were higher in the group with orthostatic hypertension than in healthy children, whereas daily water intake and sleep duration were lower. Logistic regression analyses showed that, if a child suffered from overweight, suffered from obesity, had a daily water intake of less than 800 mL, or had a red blood cell distribution width that was increased by 1%, the risk of orthostatic hypertension would be increased by 6.069 times (95% CI, 1.375-26.783; P < .05), 7.482 times (95% CI, 1.835-30.515; P < .01), 4.027 times (95% CI, 1.443-11.241; P < .01), or 4.008 times (95% CI, 1.698-9.461; P < .01), respectively. However, if the sleep duration was increased by 1 hour, the risk of developing orthostatic hypertension would be decreased by 74.3% (95% CI, 54.6%-85.4%, P < .01). CONCLUSIONS Increased body mass index, inadequate water intake and sleep duration, and elevated red blood cell distribution width were identified as risk factors for pediatric orthostatic hypertension.

Red Cell Distribution Width, Unlike Neutrophil Lymphocyte Ratio Is Unable to Accurately Gauge Enhanced Systemic Inflammation Associated With Panoramic Imaged Carotid Plaque. Mil Med 2020; 186:39-43. [PMID: 33005942 DOI: 10.1093/milmed/usaa302] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 07/15/2020] [Accepted: 08/14/2020] [Indexed: 11/13/2022] Open
Abstract
INTRODUCTION We have previously shown that panoramic X-rays (PXs) demonstrating calcified carotid artery atheromas (CCAA) are associated with increased systemic inflammation demonstrating increased neutrophil lymphocyte ratios (NLRs), a validated risk indicator of fatal myocardial infarctions arising from coronary artery atherosclerosis. Using this same cohort of patients (with minor adjustments because of missing data), we sought to determine if a like association existed between PXs evidencing CCAA and elevated red blood cell distribution width (RDW) given conflicting data as its reliability relative to NLR as a biologic marker of system inflammation. We hypothesized that CCAAs on PXs would simultaneously be associated with both increased NLR and RDW. MATERIALS AND METHODS Investigators implemented a cross-sectional study design. Study sample consisted of patient medical records and PXs of white men ≥ 55 years. Two groups (N = 50 each) were constituted, one with atheromas (CCAA+) and without atheromas (CCAA-). The predictor variable was CCAA+ and outcome variables were NLR and RDW. Bootstrapping analysis was employed to analyze the differences in mean NLRs and RDWs between groups since the data was not normally distributed. Statistical significance determined to be ≤ 0.05 for all tests. The Medical Center's Institutional Review Board approved the research protocol. RESULTS A study group of 50 CCAA+ men (mean age 71; range 58-89 years) demonstrated a mean NLR of 2.98 ± 1.38 and an RDW of 13.21 ± 0.85. A control group of 50 CCAA- males (mean age 70 range; 55-91 years) evidenced a mean NLR of 2.38 ± 0.77 and an RDW of 13.16 ± 0.77. Bootstrapping comparison of NLR values evidenced significant (P = 0.008) difference (95% confidence interval of difference of mean: - 0.4272, 0.4384; observed effect size: 0.579) between groups; however, there was no significant difference in RDW values between the groups. Furthermore, logistic regression modeling demonstrated that for a one unit increase in NLR the odds of being CCAA+ (vs. CCAA-) increases by a factor of 1.659. CONCLUSION The existence of CCAA seen on PXs of elderly white men is associated with significantly (P = 0.008) elevated NLR values but is not associated with increases in RDW.

Abstract
Background Information on the relationship between red blood cell distribution width (RDW) and atrial fibrillation (AF) in patients with essential hypertension are scarce. The study aimed to assess the relationship between AF and RDW in hypertensive patients. Methods We enrolled 432 hypertensive patients, including 350 AF patients and 82 patients as controls. Patients' demographic, clinical, laboratory and echocardiographic characteristics were recorded. The AF patients were further divided into the persistent and paroxysmal AF subgroups. Electrocardiograms were monitored to identify the cardiac rhythm during blood sampling, and based on the rhythm, the paroxysmal AF group was categorized into the presence (with AF rhythm during blood sampling) and absence (with sinus rhythm during blood sampling) groups. Results The AF group had elevated RDW levels than the controls (12.7% ± 0.8% vs. 12.4% ± 0.7%, P = 0.002), and the persistent AF subgroup had higher RDW levels than the paroxysmal AF subgroup (12.9% ± 0.8% vs. 12.6% ± 0.8%, P = 0.007). Furthermore, in the paroxysmal AF group, the presence group had higher RDW levels than the absence group (13.0% ± 0.6% vs. 12.5% ± 0.9%, P = 0.001). There was no significant difference in RDW levels between the persistent AF subgroup and presence group of the paroxysmal AF subgroup (P = 0.533) and between the absence group of the paroxysmal AF subgroup and control group (P = 0.262). In multivariate regression analysis, in hypertensive patients, the presence of AF rhythm is an independent predictor for increased RDW concentration (P = 0.001). Conclusions The RDW may be associated with the presence of AF rhythm, which implies the importance of maintaining the sinus rhythm in hypertensive patients.

Abstract
Hemoglobin level determines blood viscosity and as hemoglobin level rises, blood pressure rises. However, hemoglobin level in individuals is not fixed and change in hemoglobin is affected by various clinical conditions. The purpose of this study is to investigate whether the hemoglobin variability affects the development of hypertension using Korean cohort database. This study was conducted with 94,798 adults (age ≥ 40 years) who visited the health screening in 2006 or 2007 (index year) and had at least 3 health screenings from 2002 to 2007. Hemoglobin variability was assessed by 3 indices of coefficient of variation (CV), standard deviation, and variability independent of the mean. Cox proportional hazard regression analysis was performed for each index of quartile groups (Q1–Q4). A total of 29,145 participants (30.7%) had the incidence of hypertension during a median follow-up of 7.4 ± 2.5 years. In the multivariable adjusted model, the hazard ratio and 95% confidence interval for incidence of hypertension of Q2, Q3, and Q4 compared with Q1 of hemoglobin variability CV were 1.014 [0.981–1.047], 1.064 [1.030–1.099] and 1.094 [1.059–1.131] respectively. The results were consistent in various sensitivity and subgroup analyses. This study showed that hemoglobin variability could be associated with hypertension development.

Rondanelli M, Perna S, Alalwan TA, Cazzola R, Gasparri C, Infantino V, Perdoni F, Iannello G, Pepe D, Guido D. A structural equation model to assess the pathways of body adiposity and inflammation status on dysmetabolic biomarkers via red cell distribution width and mean corpuscular volume: a cross-sectional study in overweight and obese subjects. Lipids Health Dis 2020; 19:154. [PMID: 32590977 PMCID: PMC7320558 DOI: 10.1186/s12944-020-01308-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 06/02/2020] [Indexed: 12/21/2022] Open
Abstract
Background A study has been performed in overweight and obese subjects to assess the effects of adiposity and inflammation indicators on dysmetabolic biomarkers via red cell distribution width (RDW) and mean corpuscular volume (MCV), taking into account pro-antioxidant balance. Methods Data from 166 overweight subjects were analyzed by a path analysis model using structural equation modelling (SEM) to evaluate the direct and indirect pathway effects of adiposity, measured by body mass index (BMI) and waist circumference (WC), and inflammation status, measured by pro-antioxidant balance [reactive oxygen species (ROS)], lag-time and slope and C-reactive protein (CRP) values on dysmetabolic biomarkers, via RDW and MCV. Results BMI was strongly linked to CRP and ROS levels. Moreover, there was a significant negative decrease of MCV (1.546 femtoliters) linked to BMI indirectly via high CRP levels. Furthermore, WC affected RDW, indicating a possible mediatory role for RDW in relation to the relationship between WC and homeostatic model assessment (HOMA), insulin and high density lipoprotein (HDL), respectively. This was evident by the elevated HOMA and insulin levels and the decreased levels of HDL. Finally, ROS-related markers did not affect directly RDW and MCV. Conclusion The reported outcomes suggest that RDW might play a mediatory role in the relationship between WC and the dysmetabolic outcomes in overweight and obese individuals. CRP seems to modulate the linkage between BMI and MCV. This study provides the backbone structure for future scenarios and lays the foundation for further research on the role of RDW and MCV as suitable biomarkers for the assessment of cardiovascular disease (HDL-cholesterol), inflammatory bowels and insulin resistance.

Abstract
BACKGROUND Red cell distribution width level may have relations with the incidence and prognosis of cerebrovascular diseases. Recent researches have reported that red cell distribution width level was linked to the occurrence of stroke. However, the predicted effect of red cell distribution width in stroke is still disputed. We sought to assess the relationship between red cell distribution width and risk of stroke in this meta-analysis. METHODS Relevant studies were picked out from the databases of Embase, PubMed, and Cochrane Library. Hazard ratio with 95% confidence interval was chosen to analyze each trial, which was extracted from results of the highest and lowest red cell distribution width group. Funnel plots, Begg and Egger test were used to assess publication bias in the meta-analysis. Stata(12.0) was utilized to perform statistic analysis in the process. RESULTS A total of 6 studies with 5783 patients were included in this meta-analysis. The results showed that red cell distribution width level in patients with stroke was significantly higher than it in those without stroke (HR = 1.34, 95%CI:1.23-1.47, P < .001), in particular ischemic stroke(HR = 1.34,95% confidence interval:1.1-1.54, P < .001). There was no evidence of heterogeneity across the studies (P = .355, I = 5.53%). CONCLUSIONS The higher red cell distribution width level was associated with an increased risk of stroke, especially ischemic infarction.

Abstract
Background Red cell distribution width (RDW) reflects the volumetric heterogeneity of red blood cells (RBCs) and has proven to be a prognostic predictor for cardiovascular (CV) morbidity and mortality in ST-elevation myocardial infarction (STEMI). The study aims to evaluate the effect of the RDW admission value on the outcome of patients with STEMI. Materials and methods This is a cross-sectional observational study on (207) patients with first-ever STEMI, grouped according to their baseline RDW and thrombolysis eligibility into two groups. We calculated the in-hospital Global Registry of Acute Coronary Events (GRACE) score within 48 hours of presentation. Results The study demonstrated the impact of RDW on the primary STEMI outcomes (left ventricular ejection fraction (LVEF%), ST-resolution, arrhythmias, and cardiovascular mortality risk). It was nearly a gender-matched study, with a mean RDW of 14.20±1.86%. RDW>14% and age≥65 years were the strongest statistically significant independent predictors of STEMI outcome with LVEF % < 45%, ST-resolution, and CV mortality regardless of thrombolysis. The thrombolysis offers a logical significant negative relation with CV mortality. At the same time, hypertension, diabetes mellitus (DM), and smoking may cause an additional mortality burden, especially in elderly patients with high RDW who are not eligible for thrombolysis. There was a significant association between high GRACE to high RDW, with excellent specificity and sensitivity in predicting CV outcome. Conclusion The RDW is a simple to acquire index, with a good prognostic prediction of major adverse cardiovascular events (MACEs) and CV mortality in the STEMI patients. It is excellent in predicting STEMI outcomes, especially the response to thrombolysis.

Abstract
OBJECTIVE Absence of nocturnal blood pressure (BP) dipping is associated with poor health outcomes, including increased mortality. Non-dipper BP seems to be a predictor of cardiovascular damage in hypertensive patients. The aim of this study was to investigate the association of the mean platelet volume (MPV) and red cell distribution width (RDW) with nocturnal dipping/non dipping status in newly diagnosed and untreated prehypertensive non-smokers, using ambulatory BP monitoring. RESULTS Twenty-eight patients (15 males) in the dipper group and 24 patients (11 males) in the non-dipper group were evaluated in this study. The age of patients was 41.64 ± 15.01 and 37.96 ± 15.08 years in the dipper and non-dipper groups, respectively. The rate of nocturnal systolic BP drop in the dipper and non-dipper groups was 13.79 ± 3.35% (10.20-22.10) and 5.96 ± 2.87% (1.10-9.30) (P < 0.001), respectively. Also, the mean rate of nocturnal diastolic BP drop in the dipper and non-dipper groups was 17.02 ± 5.09% (10.30-26.90) and 6.19 ± 2.75% (1.20-9.70) (P < 0.001), respectively. RDW and MPV were significantly higher in non-dipper patients than dipper patients (P = 0.001 and P = 0.012, respectively). Bivariate analysis revealed that MPV was inversely correlated with the nocturnal systolic BP drop (P = 0.005, r = - 0.385). Furthermore, RDW was inversely correlated with systolic BP drop (P = 0.019, r = - 0.324).

Abstract
Several markers and prognostic scores have been identified for predicting the development and progression of liver disease; among them, haematological parameters (the neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW), RDW to platelet ratio (RPR), mean platelet volume (MPV), and mean corpuscular volume (MCV)) have recently gained significant interest. Compared with traditional prognostic factors, haematological indices are easy to obtain and relatively inexpensive. There is growing evidence that these haematological indices play a key role in HBV-related liver diseases and has been proposed as a predictive marker of adverse outcomes in these patients. This article focuses on discussing the diagnostic and prognostic value of the haematological indices in patients with HBV-related liver diseases.

Abstract
Red cell distribution width (RDW), a measure of variation in red blood cell size, is routinely reported in the results of a complete blood count. Recent studies have found that RDW is a predictor of high cardiovascular morbidity and mortality. Furthermore, previous cross-sectional studies have shown a possible association between high RDW and hypertension. However, the longitudinal relationship between high RDW and incident hypertension is uncertain. The aim of this study was to investigate the association between RDW and the development of hypertension. In this retrospective cohort study, we analyzed 124,261 participants without hypertension at baseline who underwent two health checkups at 4-year intervals from 2005 to 2016. The subjects were divided into quartiles (Q1-Q4) according to their baseline RDW levels. Multivariate logistic regression was used to estimate the OR and 95% CI for the development of hypertension after 4 years. After 4 years, 6827 cases (5.5%) of incident hypertension were observed. The incidence rates of hypertension were 4.66%, 5.66%, 5.99%, and 5.46% for Q1, Q2, Q3 and Q4 of RDW, respectively. The ORs (95% CIs) for incident hypertension compared with Q1 were 1.19 (1.10-1.29), 1.28 (1.18-1.39), and 1.32 (1.22-1.44) for Q2, Q3, and Q4 of RDW, respectively. High RDW was significantly and independently associated with the development of hypertension in Korean adults. Further research is warranted to verify the mechanism underlying this relationship.

Abstract
BACKGROUND There is no previously published epidemiological study exploring the association between red blood cell distribution width (RDW) and mortality in patients with cardiogenic shock (CS). The aim of this study was to examine the association between RDW and the risk of all-cause mortality in these patients. MATERIAL AND METHODS We analyzed clinical data from the MIMIC-III V1.4 database. We collected data on each patient's demographic parameters, vital signs, laboratory parameters, vital signs, comorbidities, and scoring systems on ICU admission. Cox proportional hazards models were used to assess the association between RDW levels and the 30-day, 90-day, and 365-day mortality in patients with CS. RESULTS There were 1131 patients meeting inclusion criteria in our study. In multivariate analysis, following adjustment for age, sex, and ethnicity, higher RDW in tertiles and quintiles were all associated with increased risk of 30-day, 90-day, and 365-day all-cause mortality. Furthermore, after adjusting for more relevant confounders, RDW remained a significant predictor of risk of 30-day, 90-day, and 365-day mortality (tertile 3 versus tertile 1: HR, 95% CI: 1.66, 1.19-2.31; 1.73, 1.28-2.33; 1.80, 1.38-2.34). Similarly significant robust associations were found in RDW levels stratified by quintiles. CONCLUSIONS Higher RDW is associated with increased risk of all-cause mortality in critically ill patients with CS.

Abstract
The red blood cell distribution width (RDW) is an index of the heterogeneity of circulating red blood cell size, which along with other standard complete blood count (CBC) parameters are used to identify hematological system diseases. Besides hematological disorders, several clinical studies have shown that an increased in the RDW may be associated with other diseases including acute pancreatitis, chronic kidney disease, gastrointestinal disorders, cancer, and of special interest in this review, cardiovascular disease (CVD). The diagnostic and prognostic value of RDW in different CVD (acute coronary syndrome, ischemic cerebrovascular disease, peripheral artery disease, atrial fibrillation, heart failure, and acute ischemic stroke) has been reviewed in this article, to provide an understanding how its measurement may be applied to improve the management of these conditions.

Abstract
Major advances in coronary interventional techniques and pharmacotherapy as well as the use of drug-eluting stents (DESs) have considerably reduced the risk of in-stent restenosis (ISR). However, ISR remains a major clinical challenge. Inflammation and platelet activation are important processes that underlie the pathophysiology of ISR. Parameters related to blood cells, entailing both cell count and morphology, are useful markers of the inflammatory response and platelet activation in clinical practice. Recent studies have highlighted several new combined or derived parameters related to blood cells that independently predict ISR after DES implantation. The neutrophil/lymphocyte ratio, an inflammatory marker, is regarded as a predictor of the risk of ISR and the stability of atherosclerotic plaques. The mean platelet volume, a widely used platelet activation parameter, has been shown to be a predictor of the risk of ISR and the efficacy of antiplatelet therapy. Other markers considered include the platelet/lymphocyte ratio, red blood cell distribution width, and platelet distribution width. This review provides an overview of these parameters that may help stratify the risk of coronary angiographic and clinical outcomes related to ISR.

Abstract
BACKGROUND The occurrence of acute respiratory distress syndrome (ARDS) significantly increases the mortality and morbidity of major burns; there are few laboratory markers that predict the development of ARDS in severe burns. This study was to investigate the relationship between complete blood count (CBC) parameters and the incidence of ARDS in severe burn patients. METHODS An eight-year retrospective study was performed on 610 severe burn patients who were admitted to the First Affiliated Hospital of Anhui Medical University and Rui Jin Hospital of Shanghai Jiao Tong University from January 2008 to December 2015. The patients were divided into two groups based on the development of ARDS. A blood sample was taken at admission and CBC parameters were examined. Univariate logistic regression analysis was used to evaluate the risk factors for the development of ARDS. RESULTS Of these 610 patients, 143 developed ARDS giving a rate of 23.44%. The percentage of deep second degree and full thickness burn, inhalation injury and red blood cell distribution width (RDW) were independently associated with the development of ARDS in severe burn patients. Every 1% increase in RDW was associated with a 29% increase in the risk to develop ARDS. CONCLUSIONS The findings of this study suggest that an elevated RDW is associated with an increased risk of ARDS and RDW is an independent risk factor in the prediction of ARDS after severe burns.

Abstract
Hematological parameters have emerged as independent determinants of high serum concentrations of uric acid (UA) and predictive factors in the evaluation of the total cardiovascular risk in patients with essential hypertensive. Here, we have investigated the possible relationships between hematological factors and serum uric acid levels in hypertensive patients recruited as part of Mashhad Stroke and Heart Atherosclerotic Disorders cohort study. Two-thousand three-hundred and thirty-four hypertensive individuals were recruited from this cohort and these were divided into two groups; those with either high or low serum UA concentrations. Demographic, biochemical, and hematological characteristics of population were evaluated in all the subjects. Logistic-regression analysis was performed to determine the association of hematological parameters with hypertension (HTN). Of the 2334 hypertensive subjects, 290 cases had low UA, and 2044 had high serum UA concentrations. Compared with the low UA group, the patients with high serum UA, had higher values for several hematological parameters, whilst platelet counts (PLT) were lower. Multiple linear regression analysis showed that PLT and serum high sensitivity-c reactive protein (hs-CRP) were correlated with serum UA level. Stepwise multiple logistic regression model confirmed that platelet distribution width (PDW) and gender were independent determinant of a high serum UA. PDW and PLT appear to be independently associated with serum UA level in patients with HTN. © 2018 BioFactors, 44(6):532-538, 2018.

Abstract
The aim of this study was to determine whether there was a significant association between red blood cell distribution width (RDW) and uric acid (UA) in a large Chinese population.This was a cross-sectional study with an enrollment of 80,298 ostensibly healthy participants (48,971 males, 31,327 females) during the period from 2011 to 2015. In the study, database was grouped by sex and the association between RDW and UA was analyzed by quartiles of RDW.UA values between different sexes and RDW subgroups were analyzed by 2-way analysis of variance and Bonferroni t tests. Prevalence of hyperuricemia in different sexes was calculated. The relationship between risks of hyperuricemia and RDW level was analyzed by binary logistic regression with or without adjustment for age and body mass index.UA values were not all the same between different sexes and RDW subgroups. Males had significantly higher hyperuricemia prevalence than females (20.00% vs 6.48%, P < .01). In addition, hyperuricemia prevalence in males decreased slightly across RDW quartiles, but was stable in females. No significant association between hyperuricemia risk and RDW was found in both sexes according to the results of multivariate logistic regression analysis. Similarly, negative results were also observed in multivariate linear analysis when both RDW and UA were considered as continuous variable.We could not find any significant relationship between RDW and UA in both sexes.

Chonnam Med J 2018; 54:113-120. [PMID: 29854676 PMCID: PMC5972124 DOI: 10.4068/cmj.2018.54.2.113] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Revised: 03/30/2018] [Accepted: 04/03/2018] [Indexed: 02/03/2023] Open
Abstract
Little is known as to why elevated red cell distribution width (RDW) is associated with adverse clinical outcomes in patients with atrial fibrillation (AF). We hypothesized that RDW value might predict the intensity of anticoagulation, resulting in higher adverse events in patients with AF taking warfarin. We analyzed 657 patients with non-valuvular AF who took warfarin. The intensity of anticoagulation was assessed as mean time in the therapeutic range (TTR) and defined TTR ≥60% as an optimal intensity. The primary end-point was the composite of stroke/systemic embolism and major bleeding. The secondary end-point was the composite of stroke/systemic embolism, major bleeding and death. The relationship between the baseline RDW with TTR and clinical outcomes was assessed using categorical variables as quartiles or dichotomous variables. The mean value of TTR decreased as an increment of the RDW (45.2% vs. 44.7% vs. 40.8% vs. 35.2%, p<0.001). Primary and secondary end-points were significantly increased when TTR was less than 60% and RDW was more than 13.6%. Ratio of patients achieving optimal anticoagulation were significantly decreased as an increment of RDW. A RDW of ≥13.6% was a significant predictor for poor anticoagulation control (adjusted Odds ratio [OR] 0.43, 95% confidence interval [CI] 0.23–0.82), stroke (adjusted hazard ratio [HR] 3.86, 95% CI 1.11–13.40), primary (adjusted HR 1.88, 95% CI 1.12–3.16) and secondary end-point (adjusted HR 2.46, 95% CI 1.26–4.81). RDW was negatively associated with TTR in patients with AF. Therefore, RDW might be a useful marker for the prediction of anticoagulation response and clinical outcomes in patients with AF.

Association of red blood cell distribution width with severity of hepatitis B virus-related liver diseases. Clin Chim Acta 2018; 482:155-160. [PMID: 29627486 DOI: 10.1016/j.cca.2018.04.002] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2018] [Revised: 03/31/2018] [Accepted: 04/02/2018] [Indexed: 01/24/2023]
Abstract
BACKGROUND Red blood cell distribution width (RDW) has been indicated to be an inflammatory indicator in a variety of diseases. However, no consistent conclusions regarding it's relevance to hepatitis B virus (HBV) -related liver diseases have been made. This meta-analysis was conducted to assess the significance of RDW in HBV-related liver diseases. METHODS A comprehensive literature review was conducted using PubMed, Embase, and China National Knowledge Infrastructure (CNKI) through August 20, 2017 to identify studies that reported the association between RDW and HBV-related liver diseases. The standard mean difference (SMD) and corresponding 95% confidence interval (CI) were used to assess the associations. RESULTS Twenty-four studies met the eligibility criteria were included in the meta-analysis. These studies included 3272 HBV-infected patients and 2209 healthy controls. Chronic hepatitis B (CHB) patients had significantly increased RDW levels compared with healthy controls (SMD =1.399, 95% CI 0.971-1.827, p < 0.001]. Moreover, acute on chronic liver failure (ACLF) patients (SMD = 1.309, 95% CI 0.775-1.843, p < 0.001) and cirrhotic patients (SMD = 0.948, 95% CI 0.715-1.180, p < 0.001) had significantly elevated RDW levels compared with CHB patients. However, no statistical significance was obtained in RDW levels between cirrhosis and ACLF (SMD = 0.167, 95% CI -0.382 -0.716, p = 0.051). CONCLUSION RDW values were elevated in HBV-related liver diseases and correlated with the disease severity, suggesting that RDW levels may differentiate CHB from healthy controls and ACLF and cirrhosis from CHB but they appear to have no distinguishing characteristic between ACLF and cirrhosis.

Abstract
This study was aimed at investigating the relationship between red blood cell distribution width (RDW) and hypertension in a large health check up population in China. A population of 302,527 subjects from Wuhu was enrolled in this cross-sectional health check up study between 2011 and 2016. They consisted of 126,369 women (41.78%) and 176,158 men (58.23%) with mean age of 46.9 ± 13.4 and 48.1 ± 13.7 years, respectively. The investigations included information on demographic characteristics, physical examination, and laboratory testing. Inverted U-shape relationships were observed between RDW and hypertension with peak RDW values of 14.2 (women) and 15.2 (men). After stratification by sex and adjusted with body mass index, age, white blood cells, and high-density lipoprotein cholesterol, inverted U-shape relationships were also established between RDW and hypertension, systolic blood pressure, and diastolic blood pressure, with peak RDW of 14.2, 14.5, 14.5 in women and 14.2, 16.0, 14.5 in men. Inverted U-shape relationship exists between RDW and hypertension, systolic blood pressure, and diastolic blood pressure among the Chinese health check up population studied.

Abstract
Hyperhomocysteinemia and increased red cell distribution width (RDW) are associated with a higher possibility of adverse clinical outcomes of hypertension. The study aims to validate the effect of homocysteine (Hcy) and RDW on cardiovascular events (CVE) and investigate whether RDW is independently associated with serum Hcy in patients with essential hypertension (EH). The study reviewed 804 patients with newly diagnosed EH in our hospital. The clinical characteristics and laboratory results of all subjects were grouped according to the presence/absence of CVE. Patients in the CVE group had higher RDW and Hcy, as compared to the patients in the no CVE group. Multiple Cox regression analysis demonstrated that both RDW (HR = 1.24, 95% CI =1.02-1.56, P = 0.002) and Hcy (HR = 1.37, 95% CI = 1.02-1.80, P < 0.001) resulted significantly related to the CVE. Subsequent analysis found that patients with high RDW had higher Hcy levels as compared with those with low RDW (P = 0.007). Although Pearson's correlation suggested that RDW was positively correlated with Hcy (r = 0.122, P = 0.028), no significant correlation was observed between RDW and Hcy (β = 0.15, p = 0.126) after adjusted for a series of potential confounders using multiple linear regression analysis. In conclusion, RDW is not correlated with Hcy in patients with EH. Both RDW and Hcy are independent risk factors for CVE in newly diagnostic EH and have the potential to improve risk stratification.

Abstract
The red blood cell distribution width (RDW) obtained from a standard complete blood count (CBC) is a convenient and inexpensive biochemical parameter representing the variability in size of circulating erythrocytes. Over the past few decades, RDW with mean corpuscular volume (MCV) has been used to identify quite a few hematological system diseases including iron-deficiency anemia and bone marrow dysfunction. In recent years, many clinical studies have proved that the alterations of RDW levels may be associated with the incidence and prognosis in many cardiovascular and cerebrovascular diseases (CVDs). Therefore, early detection and intervention in time of these vascular diseases is critical for delaying their progression. RDW as a new predictive marker and an independent risk factor plays a significant role in assessing the severity and progression of CVDs. However, the mechanisms of the association between RDW and the prognosis of CVDs remain unclear. In this review, we will provide an overview of the representative literatures concerning hypothetical and potential epidemiological associations between RDW and CVDs and discuss the underlying mechanisms.

Abstract
BACKGROUND Immuno-inflammation plays a major role in the process of hypertension. We aimed to evaluate the association between inflammatory markers, neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW) and all-cause mortality in elderly patients with hypertension. METHODS A total of 341 hypertensive patients over 80 years of age were included to this study. The NLR and RDW were measured on admission and all the selected patients were followed up for up to 90 days. Kaplan-Meier curves were plotted to evaluate the association between the NLR and the all-cause mortality at follow-up. Using Cox regression models, we investigated the prognostic value of NLR and RDW for all-cause mortality. RESULTS Patients with higher quartile of NLR linked to high mortality in hypertensive patients at 90 day after admission (16.47%,13.25%,1.14%,1.17% respectively; χ2 = 20.581,P = 0.000). Surviving patients had lower RDW (13.61 ± 1.37 VS 14.18 ± 1.38, p = 0.041) and NLR (4.97 ± 5.72 VS 7.95 ± 6.88,p = 0.011). The receiver operating curve (ROC) of the NLR for all-cause mortality had an area under the curve (AUC) =0.714 (95%CI: 0.629-0.798, P = 0.000), with acritical value of 2.97, with sensitivity of 92.6%, and a specificity of 52.5%. The ROC of the RDW to predict all-cause mortality, had an AUC =0.654 (95%CI:0.548-0.761, P = 0.008), with acritical value of 13.2%.The Kaplan-Meier curve showed a significant difference between different NLR levels (p = 0.002). Multivariate Cox proportional hazard analysis shown 3rd quartile of NLR(RR = 9.646, 95% CI 1.302-34.457, P = 0.041) and 4th quartiles(RR = 16.451, 95% CI 2.137-66.643, P = 0.007) were found to independently predict all-cause death in hypertensive patients over 80 years of age. Higher rank of NLR was link to higher incidence of all-cause death for such patients. CONCLUSION The findings of the present study demonstrate the potential utility of NLR in risk stratification of elderly patients with hypertension to provide information for clinical treatment strategies.

Abstract
PURPOSE Red cell distribution width (RDW), expressed in femtoliters (fl), is a measure of the variation in the size of circulating erythrocytes and is often expressed as a direct measurement of the width of the distribution. We aim to observe the mean value of red cell distribution width (RDW) in hypertensive patients. Increased RDW can be used as a tool for early diagnosis, as an inflammatory marker, and a mortality indicator in hypertensive patients due to its close relation to inflammation. MATERIALS AND METHODOLOGY Hypertensive patients who had the condition for more than one year duration, diagnosed according to the Joint National Committee (JNC 7) criteria were subjected to complete blood count and RDW measurement. One hundred patients, aged between 12 years and 65 years were enrolled from the outpatient department of medicine at the Military Hospital Rawalpindi. RESULTS The mean age (± SD) of the patients was 51.48 ± 10.08 years. Out of 100 patients 69% were males whereas 31% were females. The overall frequency of hypertension more than five years was 55% subjects whereas 45% individuals had duration of hypertension less than five years. Mean RDW in females was found to be 49.35±8.42 fl while mean RDW in males was 44.78±7.11 fl. An independent sample t-test was applied to assess if there was any significant difference between age and gender. No significant difference between age and gender was found (p<0.05). The Mann-Whitney test was used to assess any association of RDW with gender. RDW values in females was found to be statistically significantly higher than in males (U=603, p=0.01). Linear regression showed that mean RDW value increased with increasing age (P <0.001). CONCLUSIONS A significant number of patients with hypertension have increased levels of RDW. Therefore, it is recommended that serum RDW should be checked regularly in patients with hypertension.

Relation of red blood cell distribution width with CHADS 2 and CHA 2DS 2-VASc score in Chinese patients with non-valvular atrial fibrillation. Int J Cardiol 2016; 228:861-864. [PMID: 27889552 DOI: 10.1016/j.ijcard.2016.11.255] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2016] [Revised: 11/09/2016] [Accepted: 11/10/2016] [Indexed: 12/22/2022]
Abstract
BACKGROUND Higher red cell distribution width (RDW) predicts adverse events in patients with cardiovascular diseases. However, there are limited data regarding the relationship between RDW and thromboembolism risk in the patients with atrial fibrillation (AF). We aimed to investigate the association between RDW and CHADS2, CHA2DS2-VASc scores used for the evaluation of thromboembolic risk in patients with non-valvular atrial fibrillation (AF). METHODS Our study included 99 patients with AF (68 paroxysmal AF; 31 persistent AF). We calculated CHADS2 and CHA2DS2-VASc risk scores for each patient, and we carefully recorded clinical characteristics as well as laboratory and echocardiographic parameters. According to CHADS2 and CHA2DS2-VASc scores, we divided the AF patients into 2 groups (low-intermediate risk and high risk group). Subsequently, we compared the aforementioned parameters between the 2 groups, and we evaluated the relationship between RDW and CHADS2/CHA2DS2-VASc score. Finally, multivariate logistic regression analysis was performed to find independent predictors of high CHADS2, CHA2DS2-VASc scores. RESULTS Patients with high CHADS2, CHA2DS2-VASc scores had older age, higher RDW, and creatinine levels, increased left atrial diameter and lower left ventricular ejection fraction, compared to the low CHADS2, CHA2DS2-VASc score group. Multivariate logistic regression analysis showed that RDW was an independent predictor for high CHADS2, CHA2DS2-VASc scores(OR: 2.184 and OR: 5.748; all P<0.05). CONCLUSION RDW is significantly correlated with CHADS2 and CHA2DS2-VASc score in the patients with AF, while is an independent predictor for high CHADS2 and CHA2DS2-VASc score.

Abstract
INTRODUCTION The blood count is a routine laboratory test prescribed to patients suffering from high blood pressure. This study aims to describe the results of blood count from hypertensive patients and to identify conditions associated. METHODS This retrospective and descriptive study concerns the period from the 1st of December 2012 to 31 th of December 2013 in the laboratory of University Hospital Center CHU-HJRB of Antananarivo. All records of results from hypertensive patients who requested blood count have been exploited. RESULTS Among 151 hypertensive patients, 91 (60.3%) had pathological blood counts. Of these, 64 (70.4%) showed one type of abnormality and 27 (29.6%) had multiple abnormalities. The anaemia (33.91%), the leukocytosis (33.04%), the polycythemia (10.43%) and the leukopenia (9.57%) are the most frequent. Among the multiple abnormalities, anaemia associated with leukocytosis is the most observed (29.6%). The microcytosis anaemia (41%) and the neutrophil polymorphonuclear leukocytosis are the most dominant (47.4%). Patients in nephrology (90%) and in endocrinology (81.3%) are the most concerned (p = 0,008). Hypertensive under 20 years old (100%) and women (61.5%) are the most affected (p > 0, 05). The seizures (100%), the edema of the lower limbs (100%) and diabetes (70%) are the signs and pathology most encountered. CONCLUSION The blood count should be prescribed for all hypertensive patients to identify the affections that will be treated simultaneously with the high blood pressure. Thus, hypertensive patients will have a good follow-up and their life expectancy will be improved.

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
BACKGROUND Red cell distribution (RDW) has been suggested to be associated with cardiovascular mortality and mortality. However, few studies have yet investigated the possible association between RDW and early-stage renal function damage in patients with primary hypertension without receiving drug treatment. Accordingly, the aim of the present study was to evaluate early-stage renal function status in patients with RDW levels. RESULTS The study included 513 primary hypertension patients (319 men and 194 women) without receiving drug treatment. Significant positive correlation was observed between albumin-to-creatinine ratio (ACR) and RDW in hypertensive patients (r = 0.531, P < 0.001). In multivariate line regression analysis, night-time SBP (B = 0.042, P < 0.001), ACR (B = 0.005, P < 0.001), and uric acid (B = 0.001, P = 0.022) were positive predictors of RDW independent of age, sex, hemoglobin, and other indexes, whereas daytime SBP (B = -0.019, P < 0.001) was inversely associated with RDW. The receiver operating characteristics curves (ROC) explored the relationship between renal function status and RDW, estimated glomerular filtration rate (eGFR), serum creatinine, and high-sensitivity C-reactive protein. The area under the curve was 0.81 (95% CI: 0.77-0.85; P < 0.001), 0.45 (95% CI: 0.39-0.50; P = 0.049), 0.49 (95% CI: 0.43-0.54; P = 0.583), and 0.49 (95% CI: 0.44-0.55; P = 0.811), respectively. Using a cutoff point of 12.8, the RDW predicted renal function status (ACR) with a sensitivity of 76% and a specificity of 70%. CONCLUSION RDW, as an easy and quick measurable index, can predict early-stage renal function damage in essential hypertensive patients without receiving drug treatment.

Abstract
Background We aimed to analyze the association between hypertension and deep vein thrombosis (DVT) after orthopedic surgery. Methods Relevant studies were identified by a search of PubMed, Embase, China National Knowledge Infrastructure, Wanfang, the Chinese Biomedical Literature, and Weipu database until December 2015. The association between hypertension and DVT after orthopedic surgery was assessed by pooled odds ratios (ORs) and 95 % confidence intervals (CIs). Heterogeneity was evaluated by the Chi-square test based on Q statistic and I2 statistics. Finally, publication bias was evaluated by Egger’s test. Results A total of 16 articles with 68,955 males and 53,057 females were eventually identified. Studies yielded effects for homogeneous (Q = 38.41, P = 0.0008, and I2 = 60.9 %). Meta-analysis showed that hypertension was associated with DVT orthopedic surgery (OR 2.89, 95 % CI 2.18–3.83, Z = 7.38, P < 0.05). No statistical evidence of publication bias was found among studies (t = 1.90, P = 0.08). The funnel plot was symmetry, and the results were reliable. Conclusions Hypertension may promote DVT after orthopedic surgery, and may be an important risk factor of DVT occurrence.

Abstract
OBJECTIVE To investigate whether red blood cell distribution width (RDW) is associated with the blood pressure (BP) reverse-dipper pattern in patients with hypertension. DESIGN Cross-sectional study. SETTING Single centre. PARTICIPANTS Patients with essential hypertension were included in our study (n=708). The exclusion criteria included age <18 or >90 years, incomplete clinical data, night workers, diagnosis of secondary hypertension, under antihypertensive treatment, intolerance for the 24 h ambulatory BP monitoring (ABPM) and BP reading success rate <70%. MEASUREMENT Physical examination and ABPM were performed for all patients in our study. The value of RDW was measured using an automated haematology analyser. STATISTICAL METHODS The distribution of RDW in patients with hypertension among different circadian BP pattern groups was analyzed using analysis of variance (ANOVA). Multinomial logistic regression was applied to explore the associations of RDW and other relevant variables with ABPM results. RESULTS There was significantly increased RDW in reverse dippers (13.52 ± 1.05) than dippers (13.25 ± 0.85) of hypertension (p=0.012). Moreover, multinomial logistic regression analysis showed that RDW (OR 1.325, 95% CI 1.037 to 1.692, p=0.024) and diabetes mellitus (OR 2.286, 95% CI 1.380 to 3.788, p=0.001) were significantly different when comparing the reverse-dipper BP pattern with the dipper pattern. However, there was no difference of RDW between the non-dipper pattern and the reverse-dipper pattern (OR 1.036, 95% CI 0.867 to 1.238, p=0.693). In addition to this, RDW was negatively correlated with the decline rate of nocturnal systolic BP (r=-0.113; p=0.003) and diastolic BP (r=-0.101; p=0.007). CONCLUSIONS Our results suggested that RDW might associate with the abnormal dipper BP patterns of either reverse dipping or non-dipping homogeneously examined with 24 h ABPM.

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.
