Platelet Parameters In Patients Research Articles

The effect of vitamin D deficiency on platelet parameters in patients with COVID-19.

Since there is very little information about the relationship between platelet parameters and vitamin D concentration in patients with COVID-19, the aim of this study is to investigate the relationship between serum vitamin D level and platelet parameters in patients with COVID-19 and to compare these parameters in patients with COVID-19 without vitamin D deficiency and, subsequently, the prognostic value of these parameters in cases of vitamin D deficiency. Seven hundred and forty-three patients diagnosed with COVID-19 were enrolled in this study. Patients were divided into two groups: those with and without vitamin D deficiency. The associations between platelet indices and vitamin D levels were analyzed by Pearson's correlation analysis and a one-way ANOVA test. Platelet count and mean platelet volume (MPV) were significantly higher in the patients with vitamin D deficiency than in the patients without vitamin D deficiency. There was a significant negative correlation between platelet count and MPV with vitamin D levels in patients with vitamin D deficiency (r = -0.835, P = 0.001 & r = -0.324, P = 0.042, respectively). Vitamin D levels in COVID-19 patients can determine the platelet count and MPV of the patients. The aforementioned results imply that maintaining an elevated concentration of vitamin D in COVID-19 patients is important because it is associated with a decrease in MPV, which in turn reduces susceptibility to diseases such as coronary artery disease.

STUDY OF CORRELATION OF PLATELET INDICES IN THE MANAGEMENT OF CORONARY ARTERY DISEASE

Objectives: The current study aimed to assess whether platelet parameters are associated with the severity of coronary artery disease (CAD) and may be regarded as risk factors; therefore, this study was done to evaluate platelet parameters in patients with CAD. Methods: This study was carried out in the Department of Medicine of Index Medical College, Hospital and Research Center. 60 CAD patients were enrolled in the study and were compared with 60 normal, healthy individuals of the same age. Those fulfilling inclusion and exclusion criteria were enrolled in the study, and the blood samples were analyzed for platelet indices firstly at the time of admission and then repeated following antiplatelettherapy. Results: Significantly higher concentrations of mean platelet volume (p<0.001) and platelet distribution width (p<0.001) were found in cases beforetreatment when compared with the controls. A significantly lower value of total platelet count (p<0.001) was found in cases before treatment when compared with the controls. Conclusion: Platelets have been associated with the development of cardiovascular diseases such as atherosclerosis and its severe outcomes such as acute myocardial infarction, unstable angina, and sudden cardiac death. The evaluation of platelet indices is considered an important factor in determining the functionality of platelets and is recognized as a promising risk indicator for atherothrombosis.

Evaluation of Platelet Parameters in Patients With Secondary Failure of Platelet Recovery and Cytomegalovirus Infection After Hematopoietic Stem Cell Transplantation.

To investigate the clinical significance of changes in platelet parameters in patients with secondary failure of platelet recovery (SFPR) and cytomegalovirus (CMV) infection after hematopoietic stem cell transplantation (HSCT). In this retrospective study, 79 patients who had undergone allogeneic HSCT (allo-HSCT), including 40 patients with SFPR and 39 patients without SFPR, were recruited. The evaluated parameters were platelet count (PLT), plateletcrit (PCT), platelet-large cell ratio (P-LCR), mean platelet volume (MPV), platelet distribution width (PDW), the incidence of CMV infection after allo-HSCT, and the correlation of SFPR and CMV infection in patients who had undergone allo-HSCT. The control group included 107 healthy donors. The SFPR group had significantly lower megakaryocyte counts, PLT, and PCT and significantly higher P-LCR, MPV, and PDW than the healthy donor and non-SFPR groups. The incidence of CMV infection was higher in SFPR patients than in non-SFPR patients. Among the patients with SFPR, P-LCR, MPV, and PDW were lower in those with CMV DNA >8000 copies/mL than in those with CMV DNA <8000 copies/mL (P < .05 for all); the CMV viral load was slightly negatively correlated with MPV (P = .0297) and P-LCR (P = .0280). We demonstrate for the first time that the level of platelet activation in SFPR patients, which was closely related to CMV infection, was higher than that in that in non-SFPR patients, and higher CMV load was associated with the inhibition of platelet activation.

Depression and Anxiety Symptoms Are Associated with Mean Platelet Volume in Autoimmune Disorders.

Platelets are increasingly considered a bridge between mental and immunological disorders. However, data relating to platelet parameters in patients with autoimmune disorders are limited. The aim of the present study was to investigate, for the first time, the association of platelet parameters with the symptoms of affective disorders in patients with autoimmune conditions. In this cross-sectional study, we measured the complete blood count (CBC), the Generalized Anxiety Disorder Scale for anxiety (GAD-7), and the Beck Depression Inventory for depression (BDI) in 121 patients with autoimmune disorders. Mean platelet volume (MPV) was positively correlated with both anxiety and depression. Platelet distribution width (PDW) was negatively correlated with anxiety and depression. Before adjustment for covariates, logistic regression analysis revealed a significant association of MPV with depression and anxiety. After adjustment for covariates, only depression was associated with MPV. The area under the ROC curve of MPV for GAD-7 determined anxiety and BDI determined depression was 0.63. Our study showed that among the CBC hematological parameters, the MPV might be a useful biomarker of depression and anxiety in patients with autoimmune disorders. Further investigations of platelet parameters in controlled prospective studies are warranted to confirm our preliminary results.

The Analysis of the Effect of Blood Transfusion on Changes of Blood Platelet Parameters in Patients with Leukemia Treated with Chemotherapy.

Objective To study and analyze the effect of blood transfusion on the change of blood platelet parameters in patients with leukemia treated with chemotherapy. Methods Ninety-eight patients with leukemia treated with chemotherapy in the First Affiliated Hospital of Xi'an Jiaotong University from January 2021 to January 2022 were selected to observe the changes of platelet parameters before and after blood transfusion. Results There was significant difference between pre-transfusion and post-transfusion indexes (platelet count, mean platelet volume, and hematocrit) (P < 0.05). After binary logistic regression analysis, the use of antibiotics (OR = 2.235), blood transfusion history (OR = 3.086), abnormal white blood cell count (OR = 1.134), and frozen plasma transfusion (OR = 3.121) were the main factors of blood platelet parameters after transfusion in leukemia patients (P < 0.05). Conclusion Blood transfusion is beneficial to improve blood platelet parameters and prevent bleeding in patients with leukemia treated with chemotherapy. Attention should be paid to patients with risk factors for poor response to blood platelet transfusion and early intervention.

Evaluation of Platelet Parameters in Patients with Preeclampsia in Comparison with Healthy Pregnant Women Referring to Ganjavian Hospital in Dezful City in 2019

Background: Preeclampsia is one of the complications of pregnancy that endangers the life of the mother and the fetus. This complication accounts for 18% of maternal mortality and is the second leading cause of maternal mortality in Iran. Various studies have shown the important role of platelets in the pathogenesis of preeclampsia. Objectives: This study was conducted to evaluate platelet parameters in patients with preeclampsia compared to healthy pregnant women who were referred to Ganjavian hospital in Dezful city in 2019. Methods: In this study, which is a retrospective case-control study, the files of women who gave birth in Ganjavian hospital in 2019 were examined. The files of the case group, which included people with preeclampsia, were selected as available samples (104 people), and the control group, which included pregnant women without preeclampsia, were randomly selected using a table of random numbers (104 cases). Criteria for entering the study in the group with preeclampsia included BP ≥ 140/90 mmHg, proteinuria of more than 300 mg in 24-hour urine or 30 mg consistently in random urine samples, and gestational age over 20 weeks. Also, people with any underlying disease, such as diabetes, chronic hypertension, known platelet disorders, multiple birth, and drug use (heparin, aspirin) in the group with preeclampsia were excluded from the study. The data of this study were analyzed using SPSS software version 20, and independent t-test, and Mann-Whitney U test at a significant level lower than 0.05. Results: There was no statistically significant difference in demographic factors between the two case and control groups. There was a statistically significant difference between the mean hemoglobin in healthy women 11.91 ± 1.30 and preeclampsia 10.89 ± 1.09 (P &lt; 0.0001). Also, according to the findings, the individuals of the two groups had a significant difference in terms of mean platelet volume (MPV): Healthy women: 10.79 ± 1.24 and preeclampsia women: 12.98 ± 1.16 (P &lt; 0.0001). Also, the results of the Mann-Whitney U test showed that there was a statistically significant difference between the number of platelets in healthy women (284.52 ± 60.58 mm3) and preeclampsia women (149.30 ± 30.38 mm3) (P &lt; 0.0001). Conclusions: Considering the importance of reducing the complications and mortality of pregnant mothers, early detection of changes in platelet factors during pregnancy can be a predictive factor in identifying people at risk for preeclampsia.

Characteristics of platelet-associated parameters and their predictive values in Chinese patients with affective disorders

ObjectivePlatelets are increasingly considered to play an important role in inflammation and are being regarded as a putative bridge linking mental diseases and inflammatory response. Platelet-associated haematological parameters including mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), systemic immune-inflammation index (SII), platelet to lymphocyte ratio (PLR), platelet to albumin ratio (PAR) and red blood cell distribution width (RDW) to platelet ratio (RPR), have been recently investigated as simple, easily available, and inexpensive inflammatory markers. In this study, we aimed is to use large-scale clinical data to study platelet parameters in patients with affective disorders, to further investigate the predictive power of platelet parameters for major depressive disorder (MDD) and bipolar disorder (BD).MethodsThe retrospective, naturalistic, cross-sectional study analysed the data of 14,007 Chinese affective disorder patients, including 4,801 patients with first-episode MDD, 4,098 patients with recurrent MDD, 3,444 patients with BD manic episodes and 1,664 patients with BD depressive episodes. Meanwhile, 6,847 healthy subjects were served as the control group. The differences in the MPV, PDW, PCT, SII, PLR, PAR, RPR and albumin among different groups were compared, and the contributing factors for the occurrence of MDD or BD were analysed.ResultsThere were significant differences in MPV, PDW, PCT, SII, PLR, RPR and albumin values among the study groups. In the subjects, patients experiencing BD manic episodes had the highest mean values of MPV and SII, patients experiencing BD depressive episodes had the lowest mean values of platelet counts and PAR, and patients with MDD had the highest mean values of PLR and RDW. The levels of MPV, PDW and albumin were independently correlated with MDD and BD, and they are important predictors for differentiating patients with MDD or BD from healthy controls.ConclusionsOur study demonstrated that different affective disorders have unique platelet parameter variation patterns, highlighting the role of platelet parameters and systemic inflammation in the pathophysiology of MDD and BD.

Description of Platelet Count Patients Infected with Corona Virus (Covid-19) with Grouping of Productive and Elderly Age

Routine hematology tests are one of the supporting tests in diagnostics to assess the severity of the disease and predict risk in COVID-19 patients, and can be used as supporting data on RT-PCR tests. Some blood tests that are widely used as monitoring tools and predicators of COVID-19 are the number of leukocytes, the number of lymphocytes, the number of neutrophils, the number of platelets and NLR (Neutrophil lymphocyte ratio). Thrombocytopenia occurs due to excessive use of tromocytes in the body as compensation for damage to lung parenchym cells, the lungs are organs where platelets are released from megacaryocytes, so this damage causes disruption of platelet maturation process. The type of research used is quantitative descriptive with the aim to find out the results of blood tests complete with platelet parameters in patients infected with the COVID-19 coronavirus at Muhammad Noer Pamekasan General Hospital. The results of the study were platelet count test results at normal productive age of 67 respondents (96%) and decreased platelet count (Thrombocytopenia) by 3 respondents (4%). While in normal elderly age a number of 26 respondents (87%) and a decreased platelet count (Thrombocytopenia) amounted to 4 respondents (13%).

Economical and easily detectable markers of digestive tumors: platelet parameters.

Aim:This study aimed to evaluate the clinical values of platelet parameters in patients with digestive tumors.Patients & methods:A total of 974 people were classified into three groups: malignant group, patients with digestive malignant tumors; benign group, patients with benign tumors; and normal group: healthy individuals.Results:Compared with the benign and normal groups, the malignant group showed significantly increased platelet count (PLT) and plateletcrit (PCT) and significantly reduced mean platelet volume (MPV) and platelet-large cell rate (P-LCR, p < 0.001). Elevated PLT and PCT and reduced MPV and P-LCR indicated poor overall survival in patients with digestive tumors.Conclusion:PLT, PCT, MPV and P-LCR were proven to be predictive biomarkers for patients with digestive malignant tumors. Elevated PLT and PCT or decreased MPV and P-LCR indicated poor overall survival.

Evaluation of Platelet Parameters in Patients With Coronary Artery Disease

Coronary artery disease (CAD) is one of the leading causes of death worldwide; therefore, identifying new risk factors to predict the severity of the disease is thought to be associated with mortality reduction. In an effort to investigate whether platelet parameters are related to the extent of CAD and can be considered as risk factors, we designed experiments to evaluate platelet parameters in these patients. In a cross‐sectional study, sixty-nine patients with CAD (including fifty-two patients with acute coronary syndrome and seventeen patients with stable angina) and sixty-four healthy volunteers were evaluated for platelet count, mean platelet volume (MPV), and platelet distribution width (PDW). Echocardiography, electrocardiogram (ECG), and coronary angiography were conducted as well. Results showed significantly higher values for MPV and PDW in patients with acute coronary syndrome as compared to patients with stable angina and healthy volunteers (P&lt;0.001 and P=0.009, respectively). There was no significant difference in platelet count between patients and healthy volunteers (P=0.379). Our results also revealed a significant difference in the ejection fraction (EF) percentage between the three groups (P=0.008). Investigating the correlation between platelet parameters and EF percentage, ECG changes, and the results of coronary angiography did not show any significant association. The present study showed that the elevated levels of MPV and PDW in patients with CAD are not related to the extent of coronary artery disease, which was estimated by echocardiography, ECG changes, and coronary angiography. Thus, these parameters cannot be considered as risk factors for coronary artery disease.

Mean Platelet Volume Has Prognostic Value in Chronic Lymphocytic Leukemia.

PurposeMean platelet volume (MPV) is a readily accessible and commonly tested hematological indicator. Recent studies revealed a significant impact of MPV on the course and prognosis of many diseases, including some types of cancer, as well as on the incidence of atrial fibrillation and bleeding. The study aimed to perform a retrospective analysis of MPV in terms of time to first treatment (TTFT) and to determine its prognostic value in the group of patients with chronic lymphocytic leukemia (CLL). Moreover, the study includes a retrospective analysis of platelet parameters in patients treated with ibrutinib concerning bleeding and atrial fibrillation.Patients and MethodsThe study included 523 patients with CLL, for 344 the most important cytogenetic aberrations were reported. The Mann–Whitney, Kruskal–Wallis, Kaplan–Meier, chi-squared, log‑rank tests and multivariate Cox proportional hazard regression model were used to analyze collected data.ResultsThe receiver operating characteristic curve analysis was performed to identify optimal cut-off value for MPV. The analysis of survival curves showed that in the group of patients with higher values of MPV TTFT was significantly longer than in the group with lower MPV (17.9 vs 36 months, p=0.0015, cut-off value for MPV= 10.4 fl). In multivariate Cox proportional hazard regression model low MPV, the presence of del11q and del13q provided independent prognostic value for TTFT (HR=0.69, 95%-CI, 0.5293 to 0.9081; p=0.0078; HR=1.76, 95%-CI, 1.3000 to 2.3882, p=0.0003, HR=0.74, 95%-Cl, 0.5674 to 0.9588, p=0.0229, respectively). In the group treated with ibrutinib, 59 patients had no significant correlation between MPV level and the incidence of therapy complications, although in the group of patients with low MPV there was a tendency for more frequent occurrence of atrial fibrillation (p=0.259).ConclusionLow MPV values are associated with unfavorable prognosis and might represent a novel, independent prognostic factor in CLL.

Predictive and prognostic values of preoperative platelet parameters in patients with gynecological tumors.

BackgroundPlatelets play a role in tumor cell growth, metastasis, and angiogenesis, and the present study aimed to evaluate diagnostic and prognostic values of platelet parameters in patients with gynecological tumors.MethodsA total of 1062 women were included. Differences of platelet parameters (platelet count [PLT], plateletcrit [PCT], mean platelet volume [MPV], platelet‐large cell rate [P‐LCR], and platelet distribution width [PDW]) between different categories were analyzed by nonparametric test. The optimal cutoff value was calculated with receiver operating characteristic analysis. Overall survivals were analyzed with Kaplan‐Meier method and log‐rank tests for univariate analysis.ResultsPlatelet count and PCT were significantly increased, and MPV and P‐LCR were significantly reduced in malign and benign gynecological tumor groups compared with the controls (P < .001); PDW had no significant differences. There were no significant differences in PLT, PCT, MPV, P‐LCR, and PDW between different tumor locations and pathologic types. The optimal cutoff values of PLT, PCT, MPV and P‐LCR were 274, 0.26, 10.08, and 24.8 (AUC: 0.661, 0.643, 0.593, 0.562), and PCT had preferable sensibility and specificity (50.84% and 70.42%) in predicting the presence of gynecological tumors. According to survival analysis, increased PLT (≥274 × 109/L) and PCT (≥0.26), and induced MPV (<10.08 fL) and P‐LCR (<24.8%) were associated with shorter overall survival.ConclusionsPlatelet count, PCT, MPV, and P‐LCR can be used as preferable auxiliary parameters for predicting the presence of gynecological tumors. Increased PLT and PCT, or decreased MPV and P‐LCR indicated a heavier tumor burden and shorter overall survival.

Preoperative plateletcrit is a Prognostic Biomarker for Survival in Patients with Non-Small Cell Lung Cancer.

Objectives: Several factors associated with the prognosis of patients with NSCLC have been reported in the literature; however, most of these factors cannot be examined preoperatively. In this study, the clinical utility of platelet parameters in patients with NSCLC who underwent curative resection was evaluated.Materials and Methods: A retrospective study on patients with NSCLC who underwent curative resection from July 2006 to September 2016 was conducted. The Cox proportional hazard regression model was applied to evaluate the variables that demonstrated effects on disease-free and overall survival (DFS and OS).Results: A total of 116 patients with NSCLC were analyzed. There were 15 patients with plateletcrit greater than 0.2755%, and 101 patients whose plateletcrit was 0.2755% or lower. Multivariate analysis identified plateletcrit higher than 0.2755% (hazard ratio [HR] = 4.18, 95% confidence interval [CI] = 1.54-11.34, P =0.004), patient age of 65 years or more (HR = 4.02, 95% CI = 1.67-9.66, P = 0.001), and stage II or IIIA disease (HR = 2.95, 95% CI = 1.26-6.87, P = 0.012) as independent factors for OS that predicted a poor prognosis. Multivariate analysis identified plateletcrit higher than 0.2755% (HR = 4.07, 95% CI = 1.52-10.94, P = 0.005), stage II or IIIA disease (HR = 5.38, 95% CI = 2.71-10.66, P < 0.001) and non-adenocarcinoma (HR = 1.92, 95% CI = 1.02-3.59, P = 0.040) as independent prognostic factors for DFS that predicted a poor prognosis.Conclusion: Our results suggest a potential role of preoperative plateletcrit as an independent prognostic marker for patients with resectable NSCLC.

Relationship between Iron Metabolism and Platelet Parameters in Patients with Iron Deficiency Anemia

To investigate the relationship between iron metabolism and thrombocytosis. iron metabolism indexes , erythrocyte and platelet parameters of iron deficiency anemia patients with thrombocytosis were collected, the correlation of platelet parameters with iron metabolism indexes and erythrocyte parameters was analysed; the difference in erythrocyte，platelet and iron parameters between severe anemia group (hemoglobin<60 g / L) and mild and moderate anemia group (hemoglobin≥60 g / L) were compared; the changes of platelet count before and after treatment were observed. There was a significant negative correlation between serum iron and platelet count (r=-0.404,P<0.01).Serum iron negatively correlated with platelet crit(r=-0.288,P<0.05). Transferrin saturation negatively correlated with platelet count and platelet crit(r=-0.353,P<0.01;r=-0.271, P<0.05).Serum ferritin and total iron binding capacity revealed no significant relation with any platelet parameters.Hemoglobin level , hematocrit and mean corpuscular hemoglobin concentration negatively correlated with platelet count(r=-0.239,P<0.05;r=-0.250,P<0.05;r=-0.339,P<0.01).There were differences in iron metabolism indexes and platelet parameters between mild to moderate anemia group and severe anemia group. After treatment, the platelet count decreased or was normal. The important iron metabolism indexes affecting platelet count are serum iron and transferrin saturation,that is,the severer iron deficiency, the higher platelet count.Patients with more severe and hypochronic anemia has higher platelet count.

The clinical observation of the platelet parameters in patients with acute myocardial infarction in plateau

Objective To investigate the clinical value of platelet parameters in patients with acute myocardial infarction(AMI) in plateau. Methods A total of 72 patients diagnosed as acute myocardial infarction in our department from January 2016 to June 2017 were enrolled into this study. Clinical data and outcomes were analyzed. Platelet parameters were measured within 24 h after AMI occurrence.The relationship between platelet distribution width (PDW), mean platelet volume (MPV), and the severity of disease, infarct size as well as short-term prognosis were further investigated. Results Compared with control group, PDW and MPV were positively correlated with the severity of disease (PPDW=0.039, PMPV=0.038) and infarct size (rPDW=0.305, P=0.009; rMPV=0.263, P=0.025). The AUC of PDW was 0.827, optimal operating point (OOP) was 16.3%, the AUC of MPV was 0.813, OOP was 13.1 fl, the AUC of GRACE was 0.865, OOP was 145. Conclusions PDW and MPV could be regarded as laboratory index to evaluate the severity of disease, infarct size, pathological changes of coronary artery and short-term prognosis of acute myocardial infarction in plateau. Key words: Plateau; Acute myocardial infarction; Platelet distribution width; Mean platelet volume; Prognosis

Analysis of preoperative blood platelet parameters in terms of diversity of epithelial ovarian cancer.

Smouldering inflammation, thrombocytosis, and platelet hyper-reactivity are linked to malignancy. The relationships between preoperative diagnostic blood morphology parameters and cancer have been the focus of much interest, because some of these parameters are correlated with advanced cancer stages and poor patient survival rates. This study aimed to perform an observational, retrospective analysis of the intradiversity of blood platelet parameters in patients with different International Federation of Gynaecology and Obstetrics (FIGO) stages and different histological types of epithelial ovarian carcinomas (EOC), and also an analysis of the overall survival rate.In all, 94 EOC patients were included in this analysis (23 mucinous, 33 serous, 20 undifferentiated, 14 endometrioid, and 4 clear cell carcinoma cases). Peripheral blood samples were collected and analyzed before drug or surgical treatment.The platelet-to-neutrophil ratio (PNR) was related to the histological type of EOC, particularly mucinous carcinoma. In patients with mucinous cancer, the PNR was significantly lower compared with patients with nonmucinous cancer, and this parameter distinguished between mucinous and nonmucinous groups of patients (area under receiver-operating characteristic [ROC] curve 0.721 ± .056; sensitivity 82.6%; specificity 61%; P < .001; ROC analysis), regardless of the FIGO stage. Moreover, elevated PNR values were correlated with lower survival rate of EOC patients.The reduced PNR, similar to the lower level of cancer antigen 125, is characteristic for mucinous ovarian carcinoma patients. Moreover, elevated PNR index might correlate with poor survival of patients.

Predictive value of platelet-to-lymphocyte ratio in exacerbation of chronic obstructive pulmonary disease.

We aimed to assess the platelet-to-lymphocyte ratio (PLR) and platelet parameters in patients with chronic obstructive pulmonary disease (COPD). A total of 60 stable COPD patients, 50 acute exacerbation COPD patients and 50 healthy controls were enrolled in this study. The platelet distribution width and PLR were higher and the mean platelet volume was lower in the COPD patients during acute exacerbation compared with the stable patients and controls. The PLR was negatively correlated with the forced expiratory volume in 1 s. The PLR may be used as a useful and easily accessible tool for evaluating the ongoing inflammation during stable period and the disease severity during acute exacerbations in COPD patients.

Are platelet indices useful in the evaluation of type 2 diabetic patients?

Introduction: Long-term complications of diabetes mellitus are a leading cause of death in people with diabetes. Recent studies suggest that platelets with altered morphology could be associated with an increased risk for developing vascular complications in diabetes. Objective: To evaluate the platelet parameters in diabetic patients and correlate these indices with microvascular and macrovascular complications of the disease. Materials and methods: We analyzed platelet parameters and biochemical data of patients seen in outpatient clinics of a university hospital. Individuals aged between 30 and 60 years were included, 100 patients with type 2 diabetes mellitus (T2DM) (DM group) and 100 non-diabetic patients (control group). Results: We observed increase in plateletcrit (PCT): 0.21 ± 0.054% vs 0.20 ± 0.045% (p = 0.020); in mean platelet volume (MPV): 8.69 ± 1.288 fl vs 8.27 ± 1.244 fl (p = 0.018); and in platelet distribution width (PDW): 17.8 ± 1.06 fl vs 17.5 ± 0.87 fl (p = 0.039) in the DM and control groups, respectively. Values of MPV, PCT, and PDW were higher among patients with complications of T2DM (p < 0.001). In those with macrovascular disease, we observed a correlation between glycated hemoglobin (A1C) and MPV (p = 0.015) and PDW (p = 0.009) levels. Among patients with microvascular complications, there was a correlation between platelet count and MPV with A1C levels (p < 0.001). Conclusion: The study findings point to significant differences in platelet parameters in patients with T2DM, suggesting the presence of more reactive and aggregatable platelets in this group of individuals. These results suggest that platelet evaluation may be useful in the early detection of long-term complications in diabetic patients, considering that it is a simple and low-cost tool.
