Front Cardiovasc Med 2024; 11:1396889. [PMID: 39081365 PMCID: PMC11286402 DOI: 10.3389/fcvm.2024.1396889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Accepted: 07/02/2024] [Indexed: 08/02/2024] Open
Abstract
Background Acute kidney injury (AKI) represents a significant complication following cardiac surgery, associated with increased morbidity and mortality rates. Despite its clinical importance, there is a lack of universally applicable and reliable methods for the early identification and diagnosis of AKI. This study aimed to examine the incidence of AKI after cardiac surgery, identify associated risk factors, and evaluate the prognosis of patients with AKI. Method This retrospective study included adult patients who underwent cardiac surgery at Changhai Hospital between January 7, 2021, and December 31, 2021. AKI was defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Perioperative data were retrospectively obtained from electronic health records. Logistic regression analyses were used to identify independent risk factors for AKI. The 30-day survival was assessed using the Kaplan-Meier method, and differences between survival curves for different AKI severity levels were compared using the log-rank test. Results Postoperative AKI occurred in 257 patients (29.6%), categorized as stage 1 (179 patients, 20.6%), stage 2 (39 patients, 4.5%), and stage 3 (39 patients, 4.5%). The key independent risk factors for AKI included increased mean platelet volume (MPV) and the volume of intraoperative cryoprecipitate transfusions. The 30-day mortality rate was 3.2%. Kaplan-Meier analysis showed a lower survival rate in the AKI group (89.1%) compared to the non-AKI group (100%, P < 0.001). Conclusion AKI was notably prevalent following cardiac surgery in this study, significantly impacting survival rates. Notably, MPV and administration of cryoprecipitate may have new considerable predictive significance. Proactive identification and management of high-risk individuals are essential for reducing postoperative complications and mortality.

Mean platelet volume (MPV) as new marker of diabetic macrovascular complications in patients with different glucose homeostasis : Platelets in cardiovascular risk. Cardiovasc Diabetol 2024; 23:89. [PMID: 38431644 PMCID: PMC10909253 DOI: 10.1186/s12933-024-02177-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 02/24/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Platelets play an important role in the development of cardiovascular disease (CVD). Mean platelet volume (MPV) is considered as biological marker of platelets activity and function. The aim of the present study was to evaluate MPV values and its possible correlation with arterial stiffness and subclinical myocardial damage, in normal glucose tolerance patients (NGT), in newly diagnosed type 2 diabetic (T2DM) patients and in individuals with pre-diabetes. METHODS We enrolled 400 newly diagnosed hypertensive patients. All patients underwent an Oral Glucose Tolerance test (OGTT). Arterial stiffness (AS) was evaluated with the measurement of carotid-femoral pulse wave velocity (PWV), augmentation pressure (AP) and augmentation index (AI). Echocardiographic recordings were performed using an E-95 Pro ultrasound system. RESULTS Among groups there was an increase in fasting plasma glucose (FPG) (p < 0.0001), fasting plasma insulin (FPI) (p < 0.0001), high sensitivity c reactive protein (hs-CRP) levels (p < 0.0001) and a decrease in renal function as demonstrated by e-GFR values (p < 0.0001). From the NGT group to the T2DM group there was a rise in MPV value (p < 0.0001). Moreover, in the evaluation of arterial stiffness and subclinical myocardial damage, MPV showed a positive correlation with these parameters. CONCLUSIONS In the present study we highlighted that MPV is significantly increased, not only in newly diagnosed T2DM patients, but also in early stage of diabetes, indicating that subjects with pre-diabetes present increased platelets reactivity. Moreover, our results suggest that MPV is associated with increased arterial stiffness and subclinical myocardial damage, indicating MPV as new marker of CV risk.

Abstract
Aortic valve stenosis (AS) is the most common valvular disease, and surgical or transcatheter aortic valve replacement (TAVR) are the treatment options. Diminish in platelet production or dysfunction may occur due to shear stress, advanced age, and other coexisting diseases in AS patients. Bleeding is one of the complications of TAVR and associated with increased mortality. MPV (mean platelet volume) indicates platelet's thrombogenic activity. Overproduction or consumption of platelets in various cardiac conditions may affect MPV values. We aimed to investigate the pre and postprocedure MPV percentage change (MPV-PC) and its association with post-TAVR short-term complications. A total of 204 patients who underwent TAVR with a diagnosis of severe symptomatic AS were included. The mean age was 78.66 ± 6.45 years, and 49.5% of patients were women. Two groups generated according to composite end point (CEP) development: CEP(+) and CEP(-).110 patients(53.9%) formed CEP(+) group. Although baseline MPV and platelet levels were similar between groups, MPV was increased ( P < 0.001) and platelet was decreased ( P < 0.001) significantly following the procedure when compared to baseline. MPV-PC was significantly higher in the VARC type 2-4 bleeding ( P = 0.036) and major vascular, access-related, or cardiac structural complication groups ( P = 0.048) when CEP subgroups were analyzed individually. Regression analysis revealed that diabetes mellitus [ P = 0.044, β: 1.806 odds ratio (95% confidence interval): 1.016-3.21] and MPV-PC [ P = 0.007,β: 1.044 odds ratio (95% confidence interval): 1.012-1.077] as independent predictors of CEP development at 1 month after TAVR. The MPV increase following TAVR may be an indicator of adverse outcomes following TAVR procedure within 1-month.

Abstract
The key role played by platelets in the atherosclerosis physiopathology, especially in the acute setting, is ascertained: they are the main actors during thrombus formation and, thus, one of the major investigated elements related to atherothrombotic process involving coronary arteries. Platelets have been studied from different points of view, according with the technology advances and the improvement in the hemostasis knowledge achieved in the last years. Morphology and reactivity constitute the first aspects investigated related to platelets with a significant body of evidence published linking a number of their values and markers to coronary artery disease and cardiovascular events. Recently, the impact of genetics on platelet activation has been explored with promising findings as additional instrument for patient risk stratification; however, this deserves further confirmations. Moreover, the interplay between immune system and platelets has been partially elucidated in the last years, providing intriguing elements that will be basic components for future research to better understand platelet regulation and improve cardiovascular outcome of patients.

Abstract
Psoriasis is a chronic inflammatory skin disease with a prevalence of 0.14% to 1.99%. The underlying pathology is mainly driven by the abnormal immune responses including activation of Th1, Th17, Th22 cells and secretion of cytokines. Patients with psoriasis are more likely to develop cardiovascular disease (CVD) which has been well recognized as a comorbidity of psoriasis. As mediators of hemostasis and thromboinflammation, platelets play an important part in CVD. However, less is known about their pathophysiological contribution to psoriasis and psoriasis-associated CVD. A comprehensive understanding of the role of platelet activation in psoriasis might pave the path for more accurate prediction of cardiovascular (CV) risk and provide new strategies for psoriasis management, which alleviates the increased CV burden associated with psoriasis. Here we review the available evidence about the biomarkers and mechanisms of platelet activation in psoriasis and the role of platelet activation in intriguing the common comorbidity, CVD. We further discussed the implications and efficacy of antiplatelet therapies in the treatment of psoriasis and prevention of psoriasis-associated CVD.

Abstract
OBJECTIVE Changes of platelet distribution width (PDW) have been observed in women with unexplained recurrent pregnancy loss (URPL). However, relevant previous studies showed inconsistent results. We performed a meta-analysis to comprehensively evaluate the association between PDW and URPL. METHODS Observational studies reporting the difference of PDW between women with and without URPL were retrieved by searching PubMed, Embase, Web of Science, Wanfang, and CNKI. A random-effect model was used to pool the results by incorporating potential heterogeneity. RESULTS Eleven case-control studies with 1847 women with URPL and 2475 healthy women were included. Age was matched for all studies between cases and controls. Pooled results showed women with URPL had significantly increased level of PDW (mean difference [MD]: 1.54%, 95% CI: 1.04 to 2.03, p < 0.05; I2 =77%). Subgroup analysis showed consistent result for URPL defined as ≥ 2 (MD: 1.45%, p = 0.003) and ≥ 3 (MD: 1.61%, p < 0.001) failed clinical pregnancies, and in studies compared to women with normal pregnancy (MD: 2.02%, p < 0.001) and non-pregnant healthy women (MD: 1.34%, p < 0.001). Results of the meta-analysis also showed that increment of PDW was associated with higher odds of URPL (per 1 unit, odds ratio: 1.26, 95% CI: 1.17 to 1.35, p < 0.001; I2 = 0%). CONCLUSIONS Women with URPL had significantly increased levels of PDW compared to healthy women without URPL, which suggest that higher PDW may predict the risk of URPL.

Abstract
PURPOSE To retrospectively describe the association between thyroid hormones (TH) and platelet activation, as represented by mean platelet volume (MPV), in a cohort of patients hospitalized for COVID-19 with no known thyroid disease, and to correlate these data with the severity of COVID-19 and the occurrence of death/ARDS (Acute Respiratory Distress Syndrome). METHODS 103 patients with real-time polymerase chain reaction (RT-PCR) testing-confirmed COVID-19 and hospitalized were enrolled. Serum samples were collected from patients upon admission before starting any treatment. Chi-squared test was used to determine the association between euthyroid sick syndrome (ESS) and COVID-19 severity. Multivariate logistic regression was performed to evaluate the best independent predictors of COVID-19 deaths/ARDS. RESULTS 39/103 (37.9%) of patients were found to have ESS, and this condition was an independent predictor for the severity of COVID-19 (p = 0.003). Lower TSH and lower FT3/FT4 ratio correlated with higher MPV (p = 0,001 and p = 0.010), with an opposite trend with respect to what has been documented in non-COVID patients. Increasing MPV and lower FT3 significantly increased the risk, in COVID-19 patients, of an adverse outcome of death/ARDS. CONCLUSION Increased platelet activation, as represented by increased MPV, has already been reported to correlate with COVID-19 severity, possibly as a consequence of cytokine release. We demonstrated, in a cohort of 103 patients with COVID-19, that MPV is inversely correlated to TH levels, in particular in the case of ESS, where downregulation of TH axis may occur in case of systemic cytokine inflammation and more severe outcomes (death/ARDS). That ESS itself may directly cause platelet activation, as demonstrated by higher MPV in these patients, is an interesting hypothesis which deserves further investigation.

Abstract
BACKGROUND Patients undergoing cardiac surgery are at significant risk of developing postoperative acute kidney injury (AKI). Neutrophil-lymphocyte ratio (NLR) is a widely available inflammatory biomarker which may be of prognostic value in this setting. METHODS We conducted a systematic review and meta-analysis of studies reporting associations between perioperative NLR with postoperative AKI. We searched Medline, Embase and the Cochrane Library, without language restriction, from inception to May 2022 for relevant studies. We meta-analysed the reported odds ratios (ORs) with 95% confidence intervals (CIs) for both elevated preoperative and postoperative NLR with risk of postoperative AKI and need for renal replacement therapy (RRT). We conducted a meta-regression to explore inter-study statistical heterogeneity. RESULTS Twelve studies involving 10,724 participants undergoing cardiac surgery were included, with eight studies being deemed at high risk of bias using PROBAST modelling. We found statistically significant associations between elevated preoperative NLR and postoperative AKI (OR 1.45, 95% CI 1.18-1.77), as well as postoperative need for RRT (OR 2.37, 95% CI 1.50-3.72). Postoperative NLR measurements were not of prognostic significance. CONCLUSIONS Elevated preoperative NLR is a reliable inflammatory biomarker for predicting AKI following cardiac surgery.

Abstract
Background Thrombosis and inflammation are crucial elements in the pathogenesis of cardiovascular disease. Hematological parameters elucidate information involving the inflammatory and blood coagulation processes. Objectives The current study explored the association of hematological parameters with EOCAD to identify specific risk factors. Design A single-center retrospective case-control study was conducted with 1693 coronary artery disease patients and 1693 controls. Methods Hematological parameters were examined through an automated analyzer. Results The basophil percentage was significantly reduced in EOCAD (0.43 ± 0.26, p < 0.001) and MI (0.33 ± 0.24, p < 0.001) groups compared with controls (0.54 ± 0.28). The eosinophil percentage was also significantly lower in EOCAD (2.21 ± 1.71, p < 0.001) and MI (1.71 ± 2.44, p < 0.001) groups compared with controls (2.41 ± 1.75). The lymphocyte percentage in patients of EOCAD and MI and controls was 31.65 ± 7.93, 25.48 ± 9.43, and 34.82 ± 7.28, respectively. A significant difference was observed among the groups (p < 0.001). Except for the mean corpuscular hemoglobin (MCH), other red blood cell (RBC) parameters significantly differed between EOCAD patients and controls. The red blood cell distribution width (RDW), hematocrit (HCT), RBC count, mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), and hemoglobin level were associated with EOCAD prevalence after adjusting for baseline differences. Platelet volume distribution width (PDW) also correlated with EOCAD prevalence (ORadjust = 1.087, 95% CI: 1.044-1.131). Conclusions Hematological parameters are closely associated with EOCAD. Moreover, leukocyte parameters correlated with the presence and severity of the disease. In addition, erythrocyte parameters were associated with the disease presence but not with the disease severity. Among the platelet parameters, only PDW was related to the disease presence.

Abstract
Platelets are formed from bone marrow megakaryocytes, circulate in blood for 7-10 days, and then are destroyed in the spleen and/or liver. Platelet production depends on the megakaryocyte population state in the bone marrow: number and size of the cells. The platelet turnover, i.e., the number of platelets passing through the bloodstream in a certain time, is determined by both the rate of their production and the rate of their destruction. The review considers laboratory markers, which are used to assess platelet production and turnover in the patients with hematologic and cardiovascular pathologies. These markers include some characteristics of platelets themselves: (i) content of reticulated ("young") forms in the blood detected by their staining with RNA dyes; (ii) indicators of the platelet size determined in hematology analyzers (mean volume, percentage of large forms) and in flow cytometers (light scattering level). Alterations of platelet production and turnover lead to the changes in blood plasma concentrations of such molecules as thrombopoietin (TPO, main mediator of megakaryocyte maturation and platelet formation in the bone marrow) and glycocalicin (soluble fragment of the membrane glycoprotein Ib detached from the surface of platelets during their destruction). Specific changes in the markers of platelet production and turnover have been observed in: (i) hypoproductive thrombocytopenias caused by suppression of megakaryocytes in the bone marrow; (ii) immune thrombocytopenias caused by accelerated clearance of the autoantibody-sensitized platelets; and (iii) thrombocytosis (both primary and reactive). The paper presents the data indicating that in patients with cardiovascular diseases an increased platelet turnover and changes in the corresponding markers (platelet size indexes and content of reticulated forms) are associated with the decreased efficacy of antiplatelet drugs and increased risk of thrombotic events, myocardial infarction, and unstable angina (acute coronary syndrome).

Abstract
BACKGROUND Platelets (PLTs) differ in glycolytic activity, resulting in rapid acidification of 'poor' storing PLT concentrates (PCs) in plasma, or depletion of glucose when stored in PLT additive solution (PAS). We aimed to understand why PLT glycolysis rates vary between donors and how this affects storage performance. STUDY DESIGN AND METHODS Buffy coats from donors <45, 45-70 and >70 years were selected and single-donor PCs in plasma or PAS-E were prepared. PCs were stored for 8 days at 22 ± 2°C and sampled regularly for analysis. Mitochondrial activity was analyzed with an Oroboros oxygraph. Age groups, or subgroups divided into quartiles based on glucose consumption, were analyzed with ANOVA. RESULTS In each comparison, PCs of the different groups were not different in volume and cellular composition. PLTs with the highest glucose consumption had a higher initial mean platelet volume (MPV) and developed higher CD62P expression and Annexin A5 binding during storage. Higher glycolytic activity in these PLTs was not a compensation for lower mitochondrial ATP production, because mitochondrial ATP-linked respiration of fresh PLTs correlated positively with MPV (R2 = 0.71). Donors of high glucose-consuming PLTs had more health-related issues. Storage properties of PCs from donors over 70 were not significantly different compared to PCs from donors younger than 45 years. CONCLUSIONS High glucose-consuming PCs developing higher activation levels, not only displayed enhanced mitochondrial activity but were also found to contain larger PLTs, as determined by MPV. Storage performance of PLTs was found to be associated with donor health, but not with donor age.

Abstract
BACKGROUND AND AIMS A better identification of the role of vitamin D in the thrombotic process of acute coronary syndrome (ACS) will help increase the therapeutic options for this important clinical condition. There is little published evidence that 25-hydroxy vitamin D (25(OH)D) serum levels can associate with platelet function and risk of thrombosis. MATERIALS AND METHODS This prospective study was conducted on 200 patients with a diagnosis of ACS, including patients with unstable angina (UA), non-ST segment elevation myocardial infarction (NSTEMI), and ST segment elevation myocardial infarction (STEMI). In addition to demographics and angiographic data, serum concentrations of 25(OH)D and MPV were recorded in all patients. RESULTS The types of ACS were STEMI (35%), NSTEMI (25%), and UA (40%). The concentrations of 25(OH)D in patients with UA, NSTEMI, and STEMI were 23.53 ± 13.26, 19.25 ± 8.09 and 14.60 ± 8.24 ng/mL respectively (P < 0.001), and the values of MPV were 9.83 ± 1.35, 10.30 ± 1.21, and 11.56 ± 1.38 fL, respectively (P < 0.001). There was a negative correlation between 25(OH)D and MPV (R = -0.320, P < 0.0001). ROC analysis illustrated a moderate predictive value (AUC 0.706; 95% CI, 0.63-0.72) in identifying the discrimination threshold of MPV (≥ 9.90 fL) for vitamin D deficiency (<20 ng/mL). CONCLUSION The current study shows an inverse association between MPV and vitamin D levels in ACS patients, especially in the subgroup of STEMI. These findings propose the effect of vitamin D on platelet size and function, suggesting its role in thrombosis and hemostasis, which might explain the link between vitamin D deficiency and cardiovascular diseases.

Abstract
Objectives: Early fetal demise (absence of cardiac activity in a visible fetus) is a very common event, but there are no reliable biomarkers to predict it. The purpose of the study was to assess the association of platelet parameters with early fetal demise.Methods: In this case-control study, we included women with normal deliveries or those ultrasound diagnosed as early fetal demise. For those who were identified with early fetal demise, the platelet parameters were analyzed before the ultrasound diagnosis, which is based on the absence of either an embryo within a gestational sac or cardiac activity in a visible embryo in the 5-10 weeks of gestation. The association between the risk of early fetal demise with the women's mean platelet volume (MPV) and platelet counts was calculated by logistic regression. Duplicate measurements of platelet aggregation were performed with VerifyNow. Results: In total, 99 women identified with early fetal demise and 170 women who had an uncomplicated pregnancy with normal delivery from January 2017 and August 2020 were included in the study. We found that platelet counts in the early fetal demise group were significantly higher than healthy pregnancies. In addition, platelet reactivity is higher in the normal delivery group than those in early fetal demise group (p < .05). High levels of platelet counts resulted in an adjusted odds ratio (OR) of 2.075 (95% confidence interval [95% CI], 1.215-3.544; p = .008) for early fetal demise. Conclusions: Increased platelet counts in the first trimester may be a predictor for the risk of early fetal demise.

Abstract
Purpose Mean platelet volume (MPV) is an indicator of platelet activation. Pancreatic β-cell dysfunction is one of the fundamental defects contributing to the development of type 2 diabetes. The aim of this study was to assess the relationship between β-cell dysfunction and MPV in nondiabetic patients with coronary artery disease (CAD). Patients and Methods A total of 1143 consecutive nondiabetic patients (874 males and 269 females; mean age 60.0±10.3 years) with CAD were recruited for this analysis. All patients were individuals who underwent coronary angiography with a suspicion of CAD. Homeostatic model assessment 2 (HOMA2) of β-cell function (HOMA2-β%) was performed, and β-cell dysfunction was defined by a HOMA2-β% in the lowest quartile. Results MPV was significantly higher in CAD patients with β-cell dysfunction than in controls [(10.6±1.0)fl vs (10.0±1.0)fl, P=0.011]. According to the multiple regression model, pancreatic β-cell dysfunction was independently associated with MPV (β=0.210, P=0.006) and age (β=0.008, P=0.028). Conclusion MPV was significantly elevated in nondiabetic CAD patients with β-cell dysfunction compared to patients with normal β-cell function.

Abstract
Background Although it has been shown that high mean platelet volume (MPV) is associated with target organ damage in hypertensive patients, the relationship between MPV and the development of long-term major adverse cardiovascular events (MACE) has not been thoroughly investigated. In this study, we investigated the relationship between MPV and long-term MACE in hypertensive patients. Methods From September 2011 to July 2017, 1507 patients with hypertension were included in this study. Ambulatory blood pressure monitoring was performed in all patients. Patients with chronic renal failure, cardiovascular disease, chronic systemic disease and white coat hypertension were excluded from the study. MACE were defined as myocardial infarction, stroke and cardiovascular mortality. Patients were followed-up until january 2020. Results The mean follow-up duration was 87 (83.3 ± 24.4) months, and 876 patients completed the study. MACE developed in 79 patients, while 797 patients were event-free. In univariate Cox regression analysis, age, diabetes mellitus (DM), MPV, creatinine, 24-hour systolic blood pressure, and non-dipper hypertension were found to be associated with the development of MACE. In multivariate Cox regression analysis, creatinine and 24-hour systolic blood pressure lost significance, and age, DM, non-dipper hypertension and MPV were found to be independent predictors for MACE development (p < 0.001, p < 0.001, p = 0.044, and p = 0.049, respectively). Conclusions MPV, age, DM, and non-dipper hypertension were independent predictors of long-term MACE in hypertensive patients.

Abstract
Platelet activation plays an important role in the progression of pulmonary embolism (PE). Mean platelet volume (MPV) can serve as a marker of platelet activity in patients with PE. Many studies have reported different results regarding the relationship. Therefore, we aimed to perform a systematic review and meta-analysis to evaluate the relationship between MPV and PE. Two reviewers independently searched relevant articles in databases from inception to April 21, 2021 and identified all studies on MPV and PE as the outcomes of interest. Further, we selected studies meeting the criteria and extracted the data. Of the 2505 publications identified, we included 18 studies after screening. Results showed MPV was significantly higher in patients with PE (0.83 fL, 95% CI: 0.38-1.28, P<0.001) than in controls. The mean difference in MPV between those who died and survivors of PE was 1.23 fL (95% CI: 0.96-1.51, P<0.001). Hence, an increased MPV is associated with PE. MPV could be a useful tool to predict the occurrence and death risk of PE together with other risk factors.

Abstract
Background: Coronary artery disease (CAD), as a most common cause of death, is mainly caused by atherosclerosis. Due to the role of inflammation in the process of atherosclerosis, in the present study, the relationship between the severity of coronary artery disease and inflammatory factors of monocyte to HDL-C ratio (MHR), platelet-to-HDL-C ratio (PHR), neutrophil to HDL-C ratio (NHR), and IL-25 was investigated.
Methods: In this cross-sectional study, 64 patients with diagnosis of coronary artery disease who were undergoing angiography in Farshchian heart center in Hamadan were studied. For each patient, the count of monocytes, neutrophils, platelet, and HDL-C, and IL-25 were measured from their blood and serum samples. Also, demographic information, such as age, gender, diabetes, smoking, and history of hypertension, was collected using a checklist. Data were described using frequency, percent, mean, and standard deviation. Statistical analysis was performed using independent t test, Mann-Whitney, Wilcoxon, and Spearman rank correlation tests, and multiple linear regression by SPSS version 25.0 SPSS Inc). P <.05 was considered as significant.
Results: The results of this study showed that IL-25 and MHR index has a significant correlation with coronary artery disease and Gensini score (P ˂.001). The PHR index was associated with coronary artery disease. Also, qualitative variables, such as history of hypertension, history of smoking, and gender, have a significant association with the severity of coronary artery disease (P <.05).
Conclusion: Among the inflammatory markers examined, IL-25 and MHR are stronger markers for assessing the severity of coronary artery disease. Simple and available IL-25 and MHR measurements may be able to, along with common risk factors and lipid profiles, predict the amount of vascular occlusion in treatment centers as an alternative of angiography as well as screening high risk patients prone to cardiovascular disease.

Abstract
Objective The mean platelet volume/platelet count (MPV/PC) ratio is an emerging biomarker in selected types of cancer. The objective of this study is to analyze the association of MPV/PC ratio with progression and survival in glioblastoma (GB) patients, with consideration of patient demographics, tumor morphology, extent of resection, molecular pathology, and oncological therapy. Methods One hundred ninety-one patients with newly diagnosed GB were analyzed retrospectively. MPV/PC ratio groups (≤ or >0.0575) were dichotomized into low-MPV/PC ratio (≤0.0575) and high-MPV/PC ratio (>0.0575) groups according to the most significant split in the log-rank test. Results A two-sided Fisher's exact test showed no significant differences in the confounders between the low- and high-MPV/PC ratio groups. The median progression-free survival (PFS) was 9.0 months (95% CI=8.0-10.0) in the low-MPV/PC ratio group (n=164) and 6.0 months (95% CI=3.0-8.9) in the high-MPV/PC group (n=28) (p=0.013). Multivariate Cox regression analysis including the O-6-methylguanine-DNA methyltransferase (MGMT) status, age (≤/>65 years), baseline Karnofsky Performance Status (KPS), and MPV/PC ratio showed high-MPV/PC ratio as a predictor of progression (p =0.04, HR=1.61, 95% CI=1.01-2.57). In the subgroup of IDH1 wild-type GBs, high MPV/PC ratio was still a significant predictor for shortened PFS (p=0.042, HR=1.60, 95% CI=1.02-2.52). MPV/PC ratio showed no significant effect in the overall survival (OS) analysis. Median OS was 15.0 months in the high-MPV/PC ratio group and 21.0 months in the low-MPV/PC ratio group (p=0.22). Conclusion MPV/PC ratio may independently predict the progression-free survival rates of patients with glioblastoma multiforme.

Abstract
Reticulated platelets (RP) are young, functionally active platelet forms which are detected by RNA staining. Their content in the circulation reflects the intensity of bone marrow thrombocytopoesis. The aim of this study was to assess in healthy volunteers the relationship between RP percentage and platelet size and activity. RP were quantitated by thiazole orange staining using flow cytometry. Platelet size indexes included mean platelet volume (MPV), platelet large cell ratio (P-LCR) measured in a Coulter type hematological analyzer and forward scattering (FSC) measured in a flow cytometer. Platelet functional activity was evaluated by expression of activated glycoprotein (GP) IIb-IIIa (PAC-1 antibody binding) and P-selectin with the use of flow cytometry. Platelets were activated by thrombin receptor activating peptide (TRAP) (10 and 1 µM) and ADP (20 and 2.5 µM). The percentage of RP in healthy volunteers varied from 2.9% to 23.8% (mean ± SD ‒ 11.7 ± 4.7%, n = 99) and correlated with all platelet size indexes: MPV, P-LCR and FCS (r from 0.452 to 0.529, p < .001, n = 87-99). On average, RP were distributed at a ratio of 9:1 between 50% subpopulations of large and small platelets according to their FSC index. Expression of GP IIb-IIIa activated form correlated with RP percentage and platelet size indexes when platelets were activated by TRAP and ADP at both applied concentrations (r from 0.309 to 0.560, p from 0.014 to < 0.001, n = 50-62). P-selectin expression correlated with RP percentage and platelet size indexes when platelets were activated by 10 µM TRAP inducing maximum expression of this activation marker (r from 0.332 to 0.556, p from 0.008 to < 0.001, n = 65), but not by weaker agonists: 1 µM TRAP, 20 and 2.5 µM ADP (r < 0.3, n = 54-66). Thus, high RP content in healthy volunteers is associated with increased platelet size and activity in the whole platelet population.

Abstract
Platelets have an important role in tumor angiogenesis, growth, and metastasis. The reciprocal interaction between cancer and platelets results in changes of several platelet characteristics. It is becoming clear that analysis of these platelet features could offer a new strategy in the search for biomarkers of cancer. Here, we review the human studies in which platelet characteristics (e.g., count, volume, protein, and mRNA content) are investigated in early-stage cancer. The main focus of this paper is to evaluate which platelet features are suitable for the development of a blood test that could detect cancer in its early stages.

Abstract
Background: Reticulated platelets (RPs) represent the young population in the circulating platelet pool, indicating platelet turnover. Preliminary studies suggested circulating levels of RPs were associated with cardiovascular events (CVEs) in patients with coronary artery disease (CAD). Methods: This study systematically searched PubMed, Scopus, Embase, and Web of Science for eligible studies which reported RPs as a prognostic factor and the incidence of CVEs in patients with CAD. The risk estimates and 95% confidence intervals (95% CI) were analyzed for adjusted and unadjusted associations separately using random-effects model. Meta-regression and subgroup analysis were used to identify the source of heterogeneity. Funnel plots, Egger's test, and trim and fill methods were used to assess the publication bias. Results: A total of six cohort studies were included in this meta-analysis. Four studies were rated as high quality with the remaining rated as moderate quality. The funnel plot, Egger's test, and trim and fill method suggested the presence of publication bias. The pooled results indicated elevated RPs were associated with a higher risk of composite CVEs [risk ratio (RR), 2.26; 95% CI, 1.72–2.98, with little heterogeneity] and cardiovascular death (RR, 2.33; 95% CI, 1.66–3.28, with little heterogeneity). Based on results of separate meta-analysis, we found RPs might be a good predictor for revascularization but not for myocardial infarction or cerebrovascular events. After adjustment of conventional prognostic factors, the pooled result still suggested the prognostic value of RPs for composite CVEs (RR, 2.00; 95% CI, 1.30–3.08; p < 0.00001, with substantial heterogeneity). Subgroup analysis and meta-regression of adjusted risk estimates revealed that the number of adjustment factors might be the source heterogeneity. Conclusion: Circulating level of RPs might be a useful prognostic marker for CVEs in patients with CAD, even after adjustment of other prognostic factors.

Abstract
AIMS/INTRODUCTION Mean platelet volume (MPV) is a widely used biological marker of platelet function and activity. Increased MPV is associated with accelerated thrombopoiesis and an elevated risk of cardiovascular disease. However, it is not known whether higher MPV is related to the pathogenesis of type 2 diabetes and diabetic macrovascular complications in Japanese patients. Therefore, we analyzed MPV and its correlation with atherosclerosis in Japanese patients with type 2 diabetes and those who had prediabetes. MATERIALS AND METHODS We divided the patients into three groups: normoglycemic patients (n = 56), prediabetes patients (n = 44) and type 2 diabetes patients group, (n = 115). We measured platelet parameters and evaluated arterial stiffness in the three groups. RESULTS Significantly higher MPV was found in the type 2 diabetes mellitus and prediabetes patients compared with normoglycemic patients. MPV was significantly correlated with fasting blood glucose and glycated hemoglobin levels. Multiple linear regression analysis showed that MPV was positively correlated with HbA1c, even after adjustment for confounding factors. In the evaluation of arterial stiffness by measuring the cardio-ankle vascular index and maximum intima-media thickness, MPV showed a positive correlation with these parameters. CONCLUSIONS These findings suggest that MPV was significantly increased in the early stage of type 2 diabetes. We showed positive correlations between MPV and HbA1c levels, and between MPV and arterial stiffness in Japanese patients with type 2 diabetes.

Abstract
OBJECTIVE To determine whether mean platelet volume (MPV) and selected single nucleotide polymorphisms (SNPs) that have been associated with MPV in genome-wide association studies relate to stroke severity, functional outcome on discharge, and 1-year mortality in patients with ischemic stroke, we retrospectively analyzed 577 patients with first-ever ischemic stroke. METHODS Genotyping of 3 SNPs (rs342293, rs1354034, rs7961894) was performed using a real-time PCR allelic discrimination assay. Multivariable regression was used to determine the association of MPV and MPV-associated SNPs with the NIH Stroke Scale (NIHSS) score on admission, modified Rankin Scale score on discharge, and data on 1-year mortality. RESULTS Rs7961894, but not rs342293 or rs1354034 SNP, was independently associated with an MPV in the highest quartile (MPV Q4). MPV Q4 was associated with significantly greater admission NIHSS (p = 0.006), poor discharge outcome (p = 0.034), and worse 1-year mortality (p = 0.033). After adjustment for pertinent covariates, MPV Q4 remained independently associated with a greater admission NIHSS score (p = 0.025). The T>C variant of rs7961894 SNP was an independent marker of a lower 1-year mortality (hazard ratio, 0.30; 95% confidence interval, 0.13-0.70; p = 0.006) in the studied population. CONCLUSION MPV is a marker of stroke severity and T>C variant of rs7961894 is independently associated with greater MPV in acute phase of ischemic stroke and relates to decreased 1-year mortality after stroke.

Abstract
Abstract
The mean platelet volume (MPV) is an easy, rapid and inexpensive laboratory parameter which basically mirrors platelet size. Due to the essential role of platelets in hemostasis, many studies have assessed the MPV value in patients with arterial and venous thrombotic disorders. These have then been summarized in some interesting meta-analyses and recent studies that will be discussed in this narrative review. Taken together, the currently available evidence suggests that the MPV may be substantially increased in concomitance with acute episodes of coronary artery disease, venous thromboembolism, portal vein thrombosis, stroke, erectile dysfunction and preeclampsia. In many of these conditions, an increased MPV value may also be associated with unfavorable outcomes. Despite these convincing findings, some important technical issues should be considered for improving the clinical usefulness of this measure. These essentially include anticoagulant, timing of sample collection, the sample storage conditions, the influence of the analytical techniques, the approaches used for its calculation, the accurate definition of reference ranges and diagnostic cut-offs, as well as the current lack of standardization, which makes data obtained with different techniques/analyzers poorly comparable. Provided that the impact of these variables can be abated or minimized, the MPV can gain a valuable role in the laboratory workout of many arterial and venous thrombotic disorders.

Abstract
AIMS Platelet-derived growth factor (PDGF) promotes liver collagen deposition, acting on hepatic stellate cells. Despite this, low serum PDGF levels were reported in chronic hepatitis C or B infection, although some studies yield the opposite result. Since PDGF may be related not only to fibrosis but also with vascular, neuronal or muscle disease, it is important to analyze its behavior in alcoholics. METHODS In total, 17 controls and 62 alcoholic patients consecutively admitted to the hospitalization unit of the Internal Medicine Service were included. We determined serum levels of PDGF C, routine laboratory evaluation, tumor necrosis factor-α, interleukin (IL)-6 and IL-8 and malondialdehyde (MDA) levels. We analyzed the relationships between PDGF and liver function, ethanol intake and inflammatory reaction by both univariate and multivariate analysis to discern which variables PDGF levels depend on. RESULTS Serum PDGF levels were significantly lower among patients (675 ± 466 pg/ml) than among controls (1074 ± 337 pg/ml; Z = 3.70; P < 0.001), and even lower among cirrhotics (549 ± 412 among cirrhotics vs 778 ± 487 among non-cirrhotics; Z = 2.33; P = 0.02). PDGF levels showed a direct correlation with prothrombin activity (ρ = 0.50; P < 0.001), platelet count (ρ = 0.44; P < 0.001) and inverse ones with bilirubin (ρ = -0.39; P = 0.002), IL-6 (ρ = -0.33; P = 0.016), IL-8 (ρ = -0.47; P < 0.001), and MDA levels (ρ = -0.44; P < 0.001). By multivariate analysis, only prothrombin activity and platelet count were independently related to PDGF. CONCLUSION PDGF-C levels are decreased in alcoholics, especially among cirrhotics. Multivariate analysis discloses that only prothrombin activity and platelet count are independently related to PDGF-C levels.

Abstract
BACKGROUND Arterial erectile dysfunction (ED) is an early sign of vascular damage. Rare evidence has been published so far as to whether subclinical hypothyroidism (SCH) affects arterial erectile function. Therefore, the objective of this study was to fill this gap. METHODS Patients with arterial ED and SCH were consecutive enrolled and randomly divided into Group A (n = 20) and Group B (n = 20). Group A was treated with levo-thyroxine (LT4) at the dose of 1 µg/kg/day for six months, whereas patients of the group B did not receive any treatment. Thyroid stimulating hormone (TSH), free-thyroxine (FT4), peak systolic velocity (PSV), International Index of Erectile Function 5-item version (IIEF-5) score, mean platelet volume (MPV), and total cholesterol were evaluated at enrollment (T0) and after six months (T1). Patients without hypertension, diabetes mellitus, dyslipidemia, not on drugs, and with normal total testosterone (TT) values were included in this study. RESULTS Group A and B did not differ for age (61.2 ± 4.8 vs. 60.3 ± 5.6 years), body-mass index (28.7 ± 2.5 vs. 28.3 ± 2.6 Kg/m2), and serum TT levels (481.2 ± 54.0 vs. 492.1 ± 59.7 ng/dL). At T0, serum TSH levels (6.5 ± 1.2 vs. 6.0 ± 1.0 µIU/mL), FT4 (8.8 ± 0.6 vs. 8.8 ± 0.6 pmol/L), PSV (26.5 ± 1.4 vs. 25.8 ± 2.1 cm/s), IIEF-5 score (8.2 ± 1.7 vs. 9.0±1.7), and total cholesterol (167.8 ± 21.7 vs. 171.6 ± 21.3 mg/dL) did not significantly differ in patients of Group A vs. those of Group B. MPV was significantly higher in Group A than in Group B (12.3 ± 0.3 vs. 11.8±0.7 fL). At T1, Group A showed significantly lower TSH (2.26 ± 0.5 µIU/mL), MPV (9.5 ± 0.3 fL), and total cholesterol (137.8 ± 29.2 mg/dL) and significantly higher FT4 (9.3 ± 0.4 pmol/L), PSV (40.0 ± 2.6 cm/s), and IIEF-5 score (20.2 ± 3.6) compared to pre-treatment values. None of these endpoints showed significant change at T1 compared to T0 in patients of group B. CONCLUSIONS Lt4 therapy is associated with an improvement of the erectile function at the vascular level, a decrease in MPV and total cholesterol. LT4 therapy should be considered in patients with arterial ED and SCH.

Abstract
Background Platelets are a major cellular component of blood and their interaction with cancer cells is well-established to influence cancer progression and metastases. The physical size of platelets may have a critical impact on the interaction with cancer cells. In this study, we explored the potential prognostic role of platelet size measured by the determination of the mean platetlet volume (MPV) in patients with pancreatic ductal adenocarcinoma (PDAC). Methods Data from 527 patients with PDAC diagnosed and treated between 2004 and 2015 at a single center were evaluated retrospectively. Associations between MPV and baseline covariates were assessed with Wilcoxon's rank-sum tests, χ2-tests, and Fisher's exact tests. Median follow-up was estimated with a reverse Kaplan-Meier estimator according to Schemper and Smith. Analysis of time-to-death was performed with Kaplan-Meier estimators, log-rank tests and uni- and multivariable Cox proportional hazards models. Results The median MPV was 10.5 femto liter (fL) [9.8-11.3], ranged from 5.9 to 17.7 fL. A large platelet volume was associated with high-grade G3/4 tumors (p=0.004) and worse overall survival (OS) in patients with metastatic disease in univariable analysis (hazard ratio [HR] per fL increase in MPV=1.13 [95% CI: 1.04-1.23, p=0.005]). In multivariable analysis of metatatic PDAC patients, the adverse association between large platelets and a higher risk-of-death prevailed (adjusted HR per doubling of MPV=2.00; 95% CI: 1.10-3.62, p=0.02). Conclusions Large platelets represent a negative prognostic factor and add an independent prognostic information to well-established factors in PDAC patients. MPV should be considered for future individual risk assessment in patients with stage IV PDAC.

Abstract
Changes of mean platelet volume (MPV) and platelet count (PC) could be a marker or a predictor of acute stroke (AS). We conducted a systematic review and meta-analysis of the published literature on the reporting of MPV and PC in AS. Studies were included in accordance with Patient Population or Problem, Intervention, Comparison, Outcomes, and Setting framework. The PRISMA strategy was used to report findings. Risk of bias was assessed with the Newcastle-Ottawa Scale. We included 34 eligible articles retrieved from the literature. PC was significantly lower in AS patients [standardized mean difference (SMD) = - 0.30, (95% CI: - 0.49 to - 0.11), N = 2492, P = .002] compared with controls (N = 3615). The MPV was significantly higher [SMD = 0.52 (95% CI: 0.28-0.76), N = 2739, P < .001] compared with controls (N = 3810). Subgroup analyses showed significantly lower PC in both ischemic stroke (Difference SMD = -0.18, 95% CI: -0.35-0.01) and hemorrhagic stroke (-0.94, -1.62 to -0.25), but only samples by citrate anticoagulant showed significantly lower result for patients compared to controls (-0.36, -0.68 to -0.04). Ischemic stroke patients had higher MPV (0.57, 0.31-0.83), and samples by Ethylenediaminetetraacetic acid (EDTA) anticoagulant showed significantly higher result for patients compared to controls (0.86, 0.55-1.17). PC and MPV appeared to be significantly different between patients with AS and control populations. MPV was significantly higher in ischemic stroke and PC was significantly lower in both ischemic and hemorrhagic strokes. These characteristics might be related to AS and associated with it. It is advisable to pay attention to elapsed time between phlebotomy and hematology analysis, anticoagulant and hemocytometer types in AS.

High mean platelet volume-to-platelet count ratio as a diagnostic maker for increased risk of liver function damage in pediatric patients with infectious mononucleosis in China. Exp Ther Med 2019; 18:4523-4527. [PMID: 31777555 DOI: 10.3892/etm.2019.8104] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Accepted: 09/10/2019] [Indexed: 01/22/2023] Open
Abstract
The aim of the present study was to provide novel laboratory indexes for infectious mononucleosis (IM) in pediatric patients. In the present prospective study, a total of 141 pediatric patients with IM and 146 healthy subjects were enrolled. The white blood cell count (WBC), red blood cell count (RBC), hemoglobin (HB), platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transferase (GGT), uric acid (UA), urea, creatinine, total cholesterol (TC) and triglycerides (TG) in peripheral blood were evaluated. WBC, ALT, AST, GGT, UA, TG, MPV and the MPV/PLT ratio in the patients were significantly higher compared with those in the controls (P<0.01), while RBC, HB, urea, TC, PLT and PDW were significantly lower in the patients (P<0.05 for PDW and P<0.01 for others). Regression analysis under stepwise adjustment indicated that PLT and MPV/PLT were significantly associated with IM (P<0.01). Furthermore, MPV/PLT was positively correlated with ALT, AST, GGT, UA and TC (P≤0.01). In the receiver operating characteristic analysis, a sensitivity of 83.7% and specificity of 76.0% regarding the prediction of IM in pediatric patients using the MPV/PLT ratio was achieved at the cutoff of MPV/PLT(%)=3.42. In conclusion, the MPV/PLT ratio may be a novel diagnostic indicator for pediatric IM and indirectly predict damage to liver function.

Abstract
PURPOSE Activated platelets have been suggested to play an important role in the pathogenesis of dementia. Recent studies have shown contradictory results concerning the relationship between blood platelet indices and cognitive performance. METHODS This cross-sectional study evaluates the relationship between basic platelet indices and cognitive and functional performance of 754 men and women, aged 60-105 years old, admitted to the geriatric hospital unit. Assessment of global cognitive function and functional ability were performed using Mini-Mental State Examination, the seven-point Clock Drawing Test, the Katz Activities of Daily Living, the Lawton Instrumental Activities of Daily Living Scale and the Vulnerable Elders Survey Questionnaire. As platelet indices, platelet count, mean platelet volume, plateletcrit and platelet distribution width were measured. RESULTS There was no significant correlation between cognitive performance and platelet indices. Out of the functional dependence questionnaires, only the Katz Activities of Daily Living and the Vulnerable Elders Survey Questionnaire were weakly correlated with platelet count (r = - 0.080 and r = 0.096) and plateletcrit (r = - 0.075 and 0.082, respectively), but these associations diminished in sex-specific analyses. CONCLUSIONS Cognitive and functional status are not systematically related to platelet indices in multimorbid hospitalized older adults.

Abstract
OBJECTIVES To determine the effect of mean platelet volume (MPV) to platelet count (PC) ratio on postoperative poor outcomes, early mortality and long-term survival rate in patients undergoing CABG. METHODS Between February 2016 and September 2018, all patients undergoing CABG in our department were retrospectively reviewed. A total of 213 consecutive patients were included in the study. RESULTS Mean age was 61.5 ± 9.7 years and mean follow-up of all patients was 1.4 ± 0.5 years. All patients were divided into two groups as high and low MPV/PC ratio in terms of 3.825 of cut-off point. 72 patients had a high MPV/PC ratio, whereas, 141 patients had low MPV/PC ratio. The rates of reoperation for early vein-graft occlusion, low cardiac output syndrome and respiratory complication were significantly higher in group 1 (p = 0.03, 0.04 and 0.01). The mean hospital length of stay was higher in group 1 (p = 0.03). MPV/PC ratio for reoperation for early vein-graft occlusion; MPV and ejection fraction for low cardiac output syndrome; hyperlipidemia, chronic renal failure history and MPV/PC ratio for sepsis; male gender, CRF history and CPB time for atrial fibrillation; age, congestive heart failure history, myocardial infarction history and CPB time for the early mortality were found to be independent predictors. Peripheral arterial diseases, USAP and MPV/PC ratio were found to be independent predictors for the late mortality. CONCLUSIONS A high MPV/PC ratio is associated with early vein-graft occlusion and poor postoperative outcomes in the early period after CABG. Furthermore, it has a negative effect on late survival.

Mean platelet volume and coronary plaque vulnerability: an optical coherence tomography study in patients with non-ST-elevation acute coronary syndrome. BMC Cardiovasc Disord 2019; 19:128. [PMID: 31142268 PMCID: PMC6542039 DOI: 10.1186/s12872-019-1115-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Accepted: 05/21/2019] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND The association between mean platelet volume (MPV) and coronary plaque vulnerability in patients with non-ST-elevation ACS (NSTE-ACS) has not been investigated. We performed a retrospective study to evaluate the association between MPV and plaque vulnerability using optical coherence tomography (OCT). METHODS Consecutive NSTE-ACS patients who underwent pre-intervention OCT examination in our center were included in this study. Features of coronary plaques in the culprit arteries were classified as rupture, nonrupture with thin-cap fibroatheroma (TCFA), and nonrupture and non-TCFA. ROC analyses were used to determine the predictive efficacy of MPV for plaque rupture, and multivariate logistic regression analysis was performed to evaluate the potential independent predictors of plaque vulnerability. RESULTS Overall, 94 patients were included in this study. We identified 17 patients with plaque rupture, 10 with nonrupture with TCFA, and 67 with nonrupture and non-TCFA. ROC analyses showed that MPV ≥ 10.5 fL was predictive of plaque rupture in NSTE-ACS patients. Univariate analyses indicated that patients with higher MPV (≥ 10.5 fL) had higher body mass index and poorer lipid profiles compared to those with lower MPV. Moreover, those with higher MPV had higher incidences of plaque rupture and thrombosis (both P < 0.05). Results of multivariate analyses showed that diabetes and higher platelet distribution width (PDW) were independent risk factors of TCFA (P = 0.032 and 0.046, respectively), while diabetes, higher BMI, higher PDW, and higher MPV were independent determinants of plaque rupture in our cohorts (P all < 0.05). CONCLUSIONS Higher MPV is independently associated with higher risk of plaque rupture as evidenced by OCT in our cohort of NSTE-ACS patients.

Abstract
AIMS Sodium glucose co-transporter-2 inhibitors have been shown to reduce cardiovascular events and heart failure in type 2 diabetic (T2D) patients with high cardiovascular risk. Dipeptidyl peptidase-4 inhibitors showed neutral effects and may increase risk of heart failure. We aimed to compare cardiometabolic effects of dapagliflozin and vildagliptin in T2D patients with coronary artery disease (CAD). METHODS Forty-nine T2D patients with CAD were randomly assigned to dapagliflozin (n = 25) or vildagliptin (n = 24) for 6 months in a double-blind fashion. Cardiometabolic parameters were collected at baseline and at the end of treatments. RESULTS Mean age was 63.2 ± 7.9 years (female 46.9%). Baseline characteristics did not differ between two groups. At 6 months, HbA1C significantly decreased in both dapaglifozin and vildagliptin groups (0.6 ± 1.0% vs 0.8 ± 1.4%, P = 0.22, respectively). There was no difference between the changes in lipid profiles. Body mass index decreased in patients receiving dapagliflozin, whereas it increased in those receiving vildagliptin (-1.27 [95% confidence interval -2.01, -0.53] vs 1.72 [0.72, 2.72] kg, P < 0.001). The reduction in systolic blood pressure and high-sensitivity troponin T was observed in the dapagliflozin group (-9.87 [-18.00, -1.15] mmHg and 2.49 [-4.50, -0.47] pg/mL) but not in vildagliptin group (-1.97 [-9.42, 5.48] mmHg and 1.98 [-0.02, 3.97] pg/mL). The mean haemoglobin increased in the dapagliflozin group, whereas the mean platelet volume increased in the vildagliptin group. There was no significant change in the inflammatory markers in both the groups. CONCLUSIONS The extraglycaemic effects of dapagliflozin and vildagliptin on cardiometabolic parameters in T2D with CAD were different. The more favourable effects of dapagliflozin compared to vildagliptin may have explained the cardiovascular benefits observed only in sodium glucose co-transporter-2 inhibitors.

Abstract
Prospective studies on the relations between platelet count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), and incident cardiovascular disease (CVD) were still limited. This study aimed to investigate the above-mentioned prospective relations in the middle-aged and older Chinese populations based on the Dongfeng-Tongji cohort. We included 31,751 participants who were free of coronary heart disease (CHD), stroke, cancer, or severely abnormal electrocardiogram at baseline. During a median follow-up of 5.9 years, we identified 5,683 incident CVD cases, including 4,423 CHD and 1,260 stroke cases. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confident intervals (CIs) for the relation analyses. Compared with participants with 146 ≤ PLT ≤ 233 10E9/L, the adjusted HR (95% CI) of those with PLT < 146 10E9/L was 0.80 (0.68 to 0.95) for incident stroke. Compared with participants with 7.3 ≤ MPV ≤ 10.3 fl, the adjusted HRs (95% CIs) of those with MPV < 7.3 fl were 0.81 (0.75 to 0.88), 0.80 (0.73 to 0.88) and 0.84 (0.71 to 1.00) for incident CVD, CHD and stroke, respectively. Compared with participants with 13.2 ≤ PDW ≤ 18.1 %, the adjusted HRs (95% CIs) of those with PDW < 13.2 % were 0.80 (0.73 to 0.87) and 0.78 (0.70 to 0.86) for incident CVD and CHD, respectively. In conclusion, lower levels of PLT and MPV were significantly related to lower risk of stroke, while lower levels of MPV and PDW were significantly related to lower risks of CVD and CHD.

Abstract
BACKGROUND The authors studied the alterations in mean platelet volume, neutrophil-to-lymphocyte ratio, and red blood cell distribution width values together with the platelet count in hospitalized patients diagnosed with Fournier gangrene to determine their association with disease prognosis. METHODS Records of patients diagnosed with Fournier gangrene were analyzed retrospectively. RESULTS Seventy-four patients (49 men and 25 women) with a mean age of 57.60 ± 15.34 years (range, 20 to 95 years) were included. Sixty-eight participants were discharged and six died during follow-up. In the discharged group, during hospitalization, there was a trend downward in neutrophil-to-lymphocyte ratio and mean platelet volume values, whereas platelet count increased significantly. In the nonsurvivor group, the neutrophil-to-lymphocyte ratio and mean platelet volume after first débridement and at the end of hospitalization were significantly higher; platelet counts at admission, after the first débridement, and at the end of hospitalization were significantly lower compared with the survivor group (p < 0.05). In correlation analysis, mortality rate was negatively correlated with platelet count at admission and after first débridement and positively correlated with the neutrophil-to-lymphocyte ratio and mean platelet volume after first débridement. Regarding the receiver operating characteristic curve analyses, a platelet count of 188,500/µl at admission and 196,000/µl after the first débridement, a neutrophil-to-lymphocyte ratio of 13.71, and a mean platelet volume of 9.25 fl after the first débridement were defined as the cutoff levels having the best sensitivities and specificities. CONCLUSIONS This study suggests that platelet count at admission and platelet count, mean platelet volume, and neutrophil-to-lymphocyte ratio after first débridement and during discharge may be included among the prognostic scores of Fournier gangrene. The authors defined some threshold values that can be used during patient follow-up. Larger prospective studies are warranted to determine the exact role of those parameters in the prognosis of Fournier gangrene. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
Background The prognostic significance of changes in mean platelet volume (MPV) during hospitalization in ST segment elevation myocardial infarction (STEMI) patients underwent primary percutaneous coronary intervention (pPCI) has not been previously evaluated. The aim of this study was to determine the association of in-hospital changes in MPV and mortality in these patients. Methods Four hundred eighty consecutive STEMI patients were enrolled in this retrospective study. The patients were grouped as survivors (n = 370) or non-survivors (n = 110). MPV at admission, and at 48–72 h was evaluated. Change in MPV (MPV at 48–72 h minus MPV on admission) was defined as ΔMPV. Results At follow-up, long-term mortality was 23%. The non-survivors had a high ΔMPV than survivors (0.37 (− 0.1–0.89) vs 0.79 (0.30–1.40) fL, p < 0.001). A high ΔMPV was an independent predictor of all cause mortality ((HR: 1.301 [1.070–1.582], p = 0.008). Morever, for long-term mortality, the AUC of a multivariable model that included age, LVEF, Killip class, and history of stroke/TIA was 0.781 (95% CI:0.731–0.832, p < 0.001). When ΔMPV was added to a multivariable model, the AUC was 0.800 (95% CI: 0.750–0.848, z = 2.256, difference p = 0.0241, Fig. 1). Also, the addition of ΔMPV to a multivariable model was associated with a significant net reclassification improvement estimated at 24.5% (p = 0.027) and an integrated discrimination improvement of 0.014 (p = 0.0198). Conclusions Rising MPV during hospitalization in STEMI patients treated with pPCI was associated with long-term mortality.

Tangal S, Ozayar A, Ener K, Gokçe MI, Haliloglu AH. Does mean platelet volume (MPV) have a role in evaluation of erectile dysfunction and its severity? Rev Int Androl 2018; 18:1-6. [PMID: 30482465 DOI: 10.1016/j.androl.2018.07.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2018] [Revised: 07/11/2018] [Accepted: 07/17/2018] [Indexed: 12/01/2022]
Abstract
PURPOSE The mean platelet volume (MPV) has important role in the pathophysiology of vascular diseases as a marker of the platelet activity. To investigate the association between mean platelet volume and erectile dysfunction (ED) and to search whether this marker can be used for diagnosis of ED. MATERIALS AND METHODS Of the 312 patients with ED of various degrees, 122 patients without ED (IIEF-5>21) were included in this prospective study. Severity of ED was determined according to IIEF-5 questionnaire. MPV, fasting serum glucose, cholesterol, low density lipoprotein (LDL) and serum testosterone levels are also recorded. The mean platelet volume was calculated by the Coulter counter technique and sexual function was determined by International Index of Erectile Function erectile function domain (IIEF-5). RESULTS The mean age of patients was 58.4 years. The mean MPV value of patients with ED was significantly higher compared to the non-ED patients (8.91 vs. 8.22, p=0.0001). The severity of ED was shown to have a positive strong correlation with MPV values (r=0.719, p=0.001). Mean serum triglyceride, glucose, total cholesterol and LDL cholesterol levels were noted higher in patients with ED. MPV values were found to be significantly higher in patients with ED. CONCLUSION MPV level shows significant correlation with severity of ED. This cheap laboratory test can have potential to be a marker of ED. Further prospective larger studies with vascular wall thickness measurements should be conducted.

Correlation of Paraoxonase-1 with the Severity of Crohn's Disease. Molecules 2018; 23:molecules23102603.

Abstract
Diagnostics of Crohn’s disease (CD) requires noninvasive biomarkers facilitating early detection and differentiation of the disease. Therefore, in this study, we aimed to determine the relationship between paraoxonase-1 (PON-1), the severity of CD, oxidative stress, and inflammation in CD. The CD activity index was based on the current classification. Plasma PON-1 was measured in 47 patients with CD, and in 23 control volunteers. Using quantitative variables such as receiver operating characteristics (ROC) (area under the curve (AUC)), the diagnostic utility of PON-1 in differentiating the severity of CD was assessed. Circulating PON-1 was found to be decreased in the CD group compared to the control group (269.89 vs. 402.56 U/L, respectively), and it correlated well with the disease activity. PON-1 correlated positively with hemoglobin (Hb) (r = 0.539, p < 0.001), hematocrit (Ht) (r = 0.48, p < 0.001), total cholesterol (TC) (r = 0.343, p < 0.001), high density lipoprotein (HDL) (r = 0.536, p < 0.001), low density lipoprotein (LDL) (r = 0.54, p < 0.001), and triglyceride (TG) (r = 0.561, p < 0.001) and correlated negatively with white blood cell count (WBC) (r = −0.262, p = 0.029), platelet count (PLT) (r = −0.326, p = 0.006), C-reactive protein (CRP) (r = −0.61, p < 0.001), and malondialdehyde (MDA) (r = −0.924, p < 0.001). PON-1 as a marker for CD differentiation possessed a sensitivity and specificity of 93.62% and 91.30%, respectively. CD was found to be associated with the decrease in the levels of PON-1, which correlates well with activity of the disease and reflects the intensification of inflammation, as well as intensified lipid peroxidation. High sensitivity and specificity of PON-1 determines its selection as a good screening test for CD severity.

Mean platelet volume and platelet distribution width levels in patients with mild psoriasis vulgaris with metabolic syndrome. Postepy Dermatol Alergol 2018; 35:367-371. [PMID: 30206448 PMCID: PMC6130145 DOI: 10.5114/ada.2017.71285] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Accepted: 05/30/2017] [Indexed: 01/08/2023] Open
Abstract
Introduction Psoriasis vulgaris (PV) is a common inflammatory skin disease characterized by incomplete differentiation and hyperproliferation of epidermal keratinocytes. Platelets play a role in inflammatory reactions and the immune response and may be activated by a variety of stimulants. Studies in recent years have shown increased incidence of metabolic syndrome (MetS) in psoriasis patients. However, the mean platelet volume (MPV) and platelet distribution width (PDW) values have not been assessed in PV accompanied by MetS. Aim To evaluate MPV and PDW levels and their association with metabolic parameters in the presence of MetS in PV patients. Material and methods A total of 76 patients with mild PV, including 38 with MetS and 38 without MetS, 38 patients with MetS without PV and 35 healthy individuals were enrolled in the study. The number of platelets, MPV, PDW, fasting blood glucose, urea, creatinine, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides, thyroid stimulating hormone, free triiodothyronine, and the free thyroxine levels were evaluated. Results Mean platelet volume and PDW levels were significantly higher in the mild PV with MetS group compared to the mild PV without MetS group, MetS without PV patients and the healthy control group (p < 0.05, for all). There was no significant difference between the mild PV without MetS group and the healthy control group in terms of MPV and PDW levels (p > 0.05, for all). There was no significant difference between the groups with MetS and without MetS in terms of the psoriasis area and severity index (PASI) (p > 0.05). The PASI was not correlated with MPV and PDW. In addition, metabolic parameters were not correlated with MPV and PDW in mild PV patients. Conclusions Mean platelet volume and PDW levels showing platelet activation increase significantly in the presence of MetS in patients with mild PV.

Abstract
BACKGROUND Mean platelet volume (MPV) is a marker of platelet size and activity, and is associated with a poor prognosis of cardiovascular disease. Studies have shown a relationship between diabetes mellitus (DM) and MPV. This study examined the relationship between admission MPV and 2-year cardiac mortality in patients with DM and stable coronary artery disease (SCAD) undergoing elective percutaneous coronary intervention (PCI). METHODS A total of 1389 patients were enrolled and divided into two groups according to MPV as fol- lows: lower MPV (n = 908, MPV ≤ 10.9 fL) and higher MPV (n = 481, MPV > 10.9 fL). RESULTS Body mass index, platelet distribution width, MPV/platelet and glycated hemoglobin (HbA1c) levels were significantly higher in the higher MPV group compared with the lower MPV group (all p < 0.05). The platelet count was significantly lower in the higher MPV group compared with the lower MPV group (p < 0.05). MPV was positively associated with HbA1c and fasting plasma glucose levels (r = 0.073 and 0.061, p = 0.007 and 0.023, respectively) in bivariate correlation analysis. The 2-year cardiac mortality rate was 0.7%, and was significantly lower in the lower MPV group than in the higher MPV group in Kaplan-Meier analysis (p = 0.019). Receiver operating characteristic analysis showed a good diagnostic value for MPV at predicting long-term cardiac mortality (area under the curve: 0.735, 95% confidence interval [CI]: 0.590-0.880, p = 0.01). Elevated MPV was a significant risk factor for 2-year cardiac mortality (hazard ratio: 2.091, 95% CI: 1.075-4.070, p = 0.030) in multivariable Cox regression analysis. CONCLUSIONS Mean platelet volume is a strong, independent prognostic factor in PCI-treated patients with DM and SCAD.

Abstract
There is little published data on the association of platelet function and 25(OH)D concentration. We investigated the associations between mean platelet volume (MPV) and 25(OH)D concentration in patients with stable coronary artery disease. Study population was divided into three groups: group 1-25(OH)D < 10 ng/mL (N = 22), group 2-25(OH)D 10-20 ng/mL (N = 42), and group 3-25(OH)D > 20 ng/mL (N = 14). Study groups shared similar demographics. MPV values were the highest in group 1, moderate in group 2, and the lowest in group 3 (11.1 vs 10.4 vs 9.8 fL P < 0.001). There was a negative correlation between MPV and 25(OH)D (R = - 0.38, P = 0.001). ROC analysis demonstrated a moderate predictive value (AUC 0.70) in identifying the discrimination thresholds of MPV (> 10.5 fL) for vitamin D deficiency and a weak predictive value (AUC 0.65) in identifying the discrimination thresholds of 25(OH)D concentration (≤ 15.5 ng/mL) for the presence of large platelets (MPV over the upper limit of normal). In conclusion, even though the effect of vitamin D on platelet size and function is probably multifactorial, our study provides further evidence linking vitamin D to thrombosis and hemostasis. Platelets are another potential element through which vitamin D deficiency could exert adverse cardiovascular outcomes.

Abstract
Mean platelet volume (MPV) was recently published as a possible marker of coronary artery disease in patients at high risk for major adverse cardiac events. Because platelets play an important role in atherosclerosis, we examined the relationship between critical limb ischemia (CLI) and MPV in patients with peripheral arterial occlusive disease (PAOD). Our study comprised 2124 PAOD patients. Univariate logistic regression was performed to analyze potential predictors for CLI. Nagelkerke's R² is reported. Cross validation was performed using the leave-one-out principle. ROC analyses were performed to identify the best cut off value for MPV predicting CLI; to this end, Youden's index was calculated. For CLI diabetes (p < 0.001, OR 2.44, 95% CI 1.97-3.02), hsCRP (p < 0.001, OR 1.01, 95% CI 1.01-1.01), age (p < 0.001, OR 1.05, 95% CI 1.04-1.06), thrombocytosis (p = 0.025, OR 1.84, 95%CI 1.08-3.14), and MPV (p = 0.003, OR 0.84, 95% CI 0.75-0.94) were significant independent predictors for CLI. ROC analysis (AUC: 0.55, 95% CI 0.52-0.58, p < 0.001) showed ≤10.2 as the best cut off value for MPV to predict CLI. As there is a significant relationship between low MPV and a high risk for CLI in PAOD patients, MPV can be used to identify patients who are likely to develop CLI.

Abstract
Mean platelet volume (MPV) is reported to be associated with the risk of venous thromboembolism (VTE) and mortality in patients with cancer. We sought to determine the association of MPV with symptomatic VTE occurrence in patients treated for newly diagnosed Hodgkin lymphoma (HL) and their outcomes. We retrospectively studied 167 consecutive adult patients treated with HL. During first-line treatment 12 (7.2%) patients developed VTE and 14 (8%) died within the observation period. The pre-chemotherapy values of MPV were significantly lower in VTE patients than those without (p=0.0343). Patients with MPV≤25th percentile (6.8 fl) had an increased risk of VTE occurrence (p=0.0244). In multivariate analysis, MPV≤25th percentile (OR 2.21; 95%CI 1.07-4.57, p=0.033), advanced stage (OR 2.08; 95%CI 1.06-4.07, p=0.033) and bulky disease (OR 2.23; 95%CI 1.16-4.31, p=0.016) were significant factors for developing VTE. Only the impact of MPV≤25th percentile on VTE-free survival rates was found. VTE occurred in 43% (n=3) of the high-risk patients of the Thrombosis Lymphoma (ThroLy) score and in 17% (n=2) of the high-risk of the Khorana Risk Score (KRS). Neither the KRS nor the ThroLy score could identify patients at a high risk of VTE with a high degree of accuracy. We expanded the ThroLy score with the addition of the MPV≤25th percentile to more accurately identify HL patients with a higher risk of VTE. Our study indicates that the pre-chemotherapy MPV value, while of no use as an overall prognosis predictor, may still represent a useful prognostic marker for a significant VTE risk especially when incorporated into VTE-risk assessment models.
