Abstract Background: Tuberculosis (TB) and type 2 diabetes mellitus (DM) are global health diseases with high morbidity and mortality. Few studies have focused on platelet indices in TB-DM coinfection patients. The objective of this work was to analyze the platelet indices in TB, DM and TB-DM patients to assess the predictive value of the platelet index for the risk of these diseases.Methods: In total, 246 patients admitted to our hospital were distributed into three groups (113 TB, 59 DM and 74 TB+DM). A total of 133 individuals were also recruited as healthy controls (HC). Platelet indices, namely, platelet count (PC), mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW), were compared among the four groups, and the relationship with inflammatory markers was explored by using statistical software.Results: Our study discovered that MPV and PCT were significantly downregulated in TB+DM patients (9.95±1.25 fL, 0.20±0.05%, P<0.0001, P=0.0121, separately) compared with DM individuals (10.92±1.17 fL, 0.22±0.04%). Moreover, the changes in MPV were significantly higher in TB+DM patients (9.95±1.25 fL, P=0.0041) than in TB patients (9.42±1.01 fL). No differences were found in PLT and PDW among the four groups (P>0.05). The sensitivity and specificity of MPV in the differential diagnosis of DM patients vs TB+DM patients were 64.9% and 66.1% (P<0.0001), respectively, and the sensitivity and specificity of MPV between TB patients and TB+DM patients was 60.8% and 66.4%, respectively (P=0.003). MPV improved the diagnosis sensitivity when it was combined with clinical parameters, such as fasting blood glucose in DM and Mycobacterium tuberculosis culture result in TB (76.3% vs 64.9%, 72.6% vs 60.8%, P<0.0001, P=0.001, respectively). In addition, the sensitivity and specificity of PCT in the differential diagnosis of DM patients vs TB+DM patients were 69.5% and 59.4%, respectively (P=0.008). PCT improved the diagnosis sensitivity when combined with fasting blood glucose in DM (72.9% vs 64.9%, P=0.004). In addition, MPV was linked to CRP (C-reactive protein) [Ed1] and ESR (erythrocyte sedimentation rate) in the TB+DM patients (r = 0.3203, P =0.0054, r = 0.2504, P=0.0307) but PCT was not (r = 0.1905, r = 0.008675, P>0.05, respectively).Conclusions: Our research shows that MPV and PCT might be good clinical laboratory markers to distinguish TB+DM patients from TB or DM individuals, thus providing support for earlier clinical diagnosis, prevention, and therapy.When defining abbreviations and acronyms, please be consistent in whether it is the abbreviated or spelled-out form that appears in parentheses.

Few studies have focused on platelet indices in TB-DM coinfection patients. The objective of this work was to analyze the platelet indices in TB, DM and TB-DM patients to assess the predictive value of the platelet index for the risk of these diseases. Methods In total, 246 patients admitted to our hospital were distributed into three groups (113 TB, 59 DM and 74 TB + DM). A total of 133 individuals were also recruited as healthy controls (HC). Platelet indices, namely, platelet count (PC), mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW), were compared among the four groups, and the relationship with inflammatory markers was explored by using statistical software. Results Our study discovered that MPV and PCT were significantly downregulated in TB + DM patients (9.95 ± 1.25 fL, 0.20 ± 0.05%, P < 0.0001, P = 0.0121, separately) compared with DM individuals (10.92 ± 1.17 fL, 0.22 ± 0.04%). Moreover, the changes in MPV were significantly higher in TB + DM patients (9.95 ± 1.25 fL, P = 0.0041) than in TB patients (9.42 ± 1.01 fL). No differences were found in PLT and PDW among the four groups (P > 0.05). The sensitivity and specificity of MPV in the differential diagnosis of DM patients vs TB + DM patients were 64.9 and 66.1% (P < 0.0001), respectively, and the sensitivity and specificity of MPV between TB patients and TB + DM patients was 60.8 and 66.4%, respectively (P = 0.003). MPV improved the diagnosis sensitivity when it was combined with clinical parameters, such as fasting blood glucose in DM and Mycobacterium tuberculosis culture result in TB (76.3% vs 64.9, 72.6% vs 60.8%, P < 0.0001, P = 0.001, respectively).

Abstract Background: Tuberculosis (TB) and type 2 diabetes mellitus (DM) are global health diseases with high morbidity and lethality . Few studies had focus on the platelet indices in TB-DM co-morbidity patients. The objective of this work was to analyze the platelet indices in TB, DM and TB+DM to assess the predictive value of platelet index for the risk of these diseases. Methods: In total, 246 patients were distribute d into three groups (113 TB, 59 DM and 74 TB+DM) admitted in our hospital along with 133 healthy controls (HC). Platelet indices namely platelet count (PC), mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW) were compared among the four groups and explored the relationship with inflammatory markers by using statistical software. Results: Our study discovered that MPV and PCT were significantly down-expressed in TB+DM patients (9.95±1.25fL, 0.20±0.05%, P <0.0001, P =0.0121, separately ) than those in DM individuals (10.92±1.17fL, 0.22±0.04%). Moreover, on comparison of TB (9.42±1.01fL), the changes of MPV were significantly higher in TB+DM patients (9.95±1.25fL, P =0.0041). No differences were found in PLT and PDW among the four groups ( P >0.05). The sensitivity and specificity of MPV in differential diagnosis of DM patients vs TB+DM patients were defined as 64.9% and 66.1% ( P <0.0001), as well as 60.8% and 66.4% of MPV in differ from TB patients and TB+DM patients ( P =0.003). MPV improved the diagnosis sensitivity when combined with clinical golden parameters as fasting blood glucose in DM and mycobacterium tuberculosis culture result in TB. In addition, the sensitivity and specificity of PCT in the differential diagnosis of DM patients vs TB+DM patients were defined as 69.5% and 59.4% ( P =0.008). PCT improved the diagnosis sensitivity when combined with fasting blood glucose in DM (72.9% vs 64.9%, P =0.004). In addition, MPV was connected with CRP and ESR in the TB+DM patients rather than PCT. Conclusions: Our research shows that MPV and PCT might be the clinical laboratory markers distinguished TB+DM patients from TB or DM individuals, thus providing support for earlier clinical diagnosis, prevention, and therapy.

ABSTRACT Context: diabetes mellitus is a global pandemic. The increased platelet activity may play a role in the development of vascular complications of this metabolic disorder. The mean platelet volume (MPV) is an indicator of the average size and activity of platelets. Larger platelets are younger and exhibit more activity. Aims: to determine the MPV in diabetics compared to nondiabetics, to see if there is a difference in MPV between diabetics with and without vascular complications, and to determine the correlation of MPV with fasting blood glucose, glycosylated hemoglobin (HbA1c), body-mass index, and duration of diabetes in the diabetic patients. Materials and Methods: platelet counts and MPV were measured in 300 Type 2 diabetic patients and 300 nondiabetic subjects using an automated blood cell counter. The blood glucose levels and HbA1c levels were also measured. Statistical evaluation was performed by SPSS using Student’s t test and Pearson correlation tests. Results: the mean platelet counts and MPV were higher in diabetics compared to the nondiabetic subjects [277.46 ± 81 X 109/l vs. 269.79 ± 78 X 109/l (P= 0.256)], 8.29 ± 0.74 fl versus 7.47 ± 0.73 fl (P= 0.001), respectively. MPV showed a strong positive correlation with fasting blood glucose, postprandial glucose and HbA1C levels (P=0.001). Conclusions: our results showed significantly higher MPV in diabetic patients than in the nondiabetic subjects. This indicates that elevated MPV could be either the cause for or due to the effect of the vascular complications. Hence, platelets may play a role and MPV can be used as a simple parameter to assess the vascular events in diabetes.

Background: Type 2 diabetes is a part of metabolic syndrome associated with a higher risk of vascular complications. Diabetes is characterized by changes in platelet morphology, function, and platelet hyperactivity so, it's considered a prothrombotic condition. Morbidity and mortality in people with type 2 diabetes-related to micro and macrovascular complications. Novel biomarkers are needed to identify and treat people at higher risk. Objective: The main objective of this controlled cross-sectional study was to evaluate Platelet volume indices (PVI) in subjects with type 2 diabetes with and without complications in comparison to subjects without diabetes. Methods: Hundred and thirty-five subjects aged from 35 to 60 years were subdivided into 3 groups. Group A includes 55 subjects with type 2 diabetes with complications. Group B includes 45 subjects with type 2 diabetes without complications. Group C includes 35 normal healthy subjects. Detailed clinical history was taken. Also, PVI, fasting blood glucose (FBG), hemoglobin A1c, and creatinine were obtained. Results: Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), Plateletcrit (PCT), and Platelet large cell ratio (P-LCR) were significantly higher among subjects with retinopathy, nephropathy, and neuropathy than other subjects with diabetes who didn't develop complications (P<0.001). At cutoff value > 11.9 fL, MPV have diagnostic sensitivity 80% and specificity 97.8%. Whereas PDW >16.9fL has a sensitivity of 74.5% and specificity of 100% for diabetic microvascular complications (retinopathy, nephropathy, and neuropathy). Conclusion: MPV and PDW may be considered as possible biomarkers for the early detection of diabetic microvascular complications.

Introduction Preeclampsia is the most serious health risk during pregnancy for both the mother and the fetus. Even though platelet parameters are among the proposed biomarkers for the prediction of preeclampsia, the use of its indices in the diagnosis of preeclampsia is not increasing in Ethiopia. There is little information on platelet patterns in preeclampsia and normal pregnancy. The purpose of this study was to determine the pattern of platelet indices in women with preeclampsia in our study setting. Methods A case-control study was conducted among 180 pregnant women who attended anti-natal follow-ups from January 1 to April 3, 2019. An Ethylene Diamine Tetra Acetic Acid anti-coagulated venous blood was collected and analyzed using a hematology analyzer (MINDRAY®-BC-300Plus, Shenzhen China). The SPSS software version 26 was used to run the Mann Whitney U test, Kruskal-Wallis H test, and Kolmogorov-Smirnov normality test, Post-hock test augmented with Benforeni, receiver operating characteristics curve, and Spear Man rank-order correlation. A P-value of <0.05 was considered statistically significant. Results A total of 180 pregnant women were included in the study. Platelet count and platelet crit levels tend to decrease as pre-eclampsia becomes more severe. In contrast, the mean platelet volume and platelet distribution widths were significantly increased with the severity of preeclampsia (P<0.001). Platelet distribution width (rho = 0.731, p<0.001) and mean platelet volume (rho = 0.674, p<0.001) had statistically significant positive relationships with mean arterial pressure. The best metric for predicting preeclampsia was platelet distribution width (AUC = 0.986; 95%CI; 0.970, 1). Conclusions Platelet indices, including platelet count, mean platelet volume, platelet distribution width, and Platelet crit, have been identified as promising candidate markers for predicting preeclampsia in pregnant women. In the future, a serial examination of these indicators during several trimesters of pregnancy should be conducted.

ABSTRACT Aims The objective of the study was to determine the mean platelet volume (MPV) and platelet distribution width (PDW) in subjects with type 2 diabetes mellitus (type 2 DM) compared to subjects without type 2 DM and their correlation with fasting blood glucose, glycosylated hemoglobin (HbA1c), and duration of type 2 DM respectively. Materials and methods A prospective analytical case—control study was conducted involving 50 subjects with type 2 DM and 50 subjects without type 2 DM. The mean and standard deviation were estimated for both the groups separately and independent Student's “t”-test was used for evaluating the significant difference. The statistical evaluation was carried out at 95% confidence level. Results Mean MPV and PDW in case group was significantly higher compared to control group (p < 0.005). Fasting blood glucose, HbA1c, and duration of type 2 DM did not significantly alter MPV or PDW. Conclusion The study concludes that MPV and PDW are significantly increased in patients with type 2 DM compared to patients without type 2 DM. Platelet volume indices are an important, simple, and cost-effective tool that should be used and explored extensively, especially in countries, such as India, for predicting the possibility of impending acute vascular events in patients with type 2 DM. Clinical significance This analytical method helps us to use MPV and PDW as early markers of vascular thrombosis. How to cite this article Bhanukumar M, Ramaswamy PKH, Peddi NK, Menon VB.

Background:Platelet activation is considered as a pivot pathogenic process to be responsible for thromboembolism in antiphospholipid syndrome (APS). severalstudies shown that platelet indices including platelet distribution width (PDW), mean platelet volume (MPV), large platelet rate (P-LCR) are associated with platelet activation.Objectives:This study aims to determine the correlation between platelet indices and thrombotic events in patients with APS.Methods:Platelet activation is considered as a pivot pathogenic process to be responsible for thromboembolism in antiphospholipid syndrome (APS). severalstudies shown that platelet indices including platelet distribution width (PDW), mean platelet volume (MPV), large platelet rate (P-LCR) are associated with platelet activation.Results:A total of 207 patients [135(65.2%) female, 72(34.8%) male], medianage 35(IQR 10)] was classified into thrombotic group (n=150,72.5%) and non-thrombotic group(n=57,27.5%). PDW, MPV, P-LCR were significantly higher in thrombotic group than non-thrombotic group (13.0±3.4 vs. 11.2±7.3)p<0.001, 10.7±1.4vs.10.0±3.0,p<0.001, 30.25±11.6vs. 25.1±10.4 p<0.001, respectively]. No differences in age, WBC count, hsCRP and C3 were observed between groups. Also, HGB was found to be notably higher in thrombotic group than non-thrombotic group (143±29 vs. 132±15, p=0.001).Upon univariate logistic analysis, PDW (OR 1.554, 95%CI 1.289-1.873, p<0.001), MPV (OR 1.772, 95%CI 1.268-2.476, p=0.001), P-LCR (OR 1.089, 95%CI 1.040-1.140, p<0.001) were all significantly associated with the occurrenceof thrombosis. In multivariate logistic analysis, only PDW and positive LAwere identified to be risk factors of thrombotic events (Table 1). The ROC curve showed that PDW combinedwith positive LAwas a reliable indicator of thrombotic events with an AUC of 0.796 (95%CI 0.728-0.864). The optimal cut-off value for PDW was 12.4fl with a sensitivity of 72.0% and specificity of 77.2%.Conclusion:This study confirmed that PDW, P-LCR and MPV (especially PDW) were significantly associated with thrombotic events in APS patients, which could support the theory of platelet activation being a crucial factor of thrombosis inAPS. Caution should be raised when patients with positive LA has relatively high PDW level.Disclosure of Interests:None declared

Background: Platelets with altered morphology or large size are more thrombogenic and are likely to be associated with increased risk of vascular disease. Platelet parameters especially high mean platelet volume (MPV) has been reported in diabetic patients as major contributing factor. The aim of the present study was to find correlation between fasting blood glucose value and hematological variables (PC and MPV), not only in diabetics, but also in the normoglycemic subjects and patients with impaired fasting blood glucose levels.Materials and Methods: In the present study 3471 subjects were analyzed retrospectively and categorized into three groups based on the fasting blood glucose levels as Group I - normoglycemics (FBG ? 109 mg/dl, n = 1158), Group II- impaired fasting blood glucose (FBG ? 126 mg/dl, n = 1158) and Group III – Diabetics (FBG ? 127 mg/dl, n = 1155).Results: We found progressive increase in value of MPV with the increasing FBG levels, in the following order: G1 (8.44 ± 0.842 fl), G2 (8.98 ± 0.898 fl), G3 (9.31 ± 0.967 fl). The platelet count however, did not show much statistical significance with rising glucose levels.Conclusions: MPV increased proportionally with increasing plasma glucose levels. Although the variation between the normoglycemics and impaired fasting group was not very significant, the parameters still showed progressive increase with rising sugar levels significant in diabetic group.Asian Journal of Medical Sciences Vol.7(1) 2015 30-33

Background: Pulmonary embolism is a common disease with a high mortality risk. It has recently been reported that platelet indices may be diagnostic in pulmonary embolism. Objective: In this study, we aimed to determine the diagnostic value of platelet indices in acute pulmonary embolism. Methods: The study group was composed of 61 patients diagnosed with pulmonary embolism and a control group of 67 subjects without pulmonary embolism. Patient age, sex, leukocyte and platelet number, hemoglobin concentration (Hb), mean platelet volume, platelet distribution width, red blood cell distribution width, C-reactive protein, D-Dimer, and troponin I levels were retrospectively analyzed and compared between the two groups. Results: There was no significant difference between age and platelet number of pulmonary embolism and control group. In pulmonary embolism group, platelet distribution width level was significantly high (p = 0.002), whereas mean platelet volume level was significantly lower (p = 0.038). Receiver operating characteristic curve analysis revealed that a mean platelet volume cut-off of 9 fL had a sensitivity of 35%, a specificity of 89.55%, and area under the curve of 0.589 for pulmonary embolism, while a platelet distribution width cut-off of 12.8 fL had a sensitivity of 61%, a specificity of 71.64%, and area under the curve of 0.661. Platelet distribution width and D-dimer levels had a significant positive correlation with each other, whereas there was no significant correlation between mean platelet volume and D-dimer. Conclusion: Platelet distribution width values of the pulmonary embolism group were higher than those of control group. Although the area under the curve of platelet distribution width is slightly better than for platelet number or mean platelet volume, it does not seem that this parameter has better diagnostic accuracy than the other two.

Introduction and Objectives: In this study, we aimed to investigate whether platelet count (PLT) and platelet indices included mean platelet volume (MPV), platecrit (PCT), platelet distribution width  (PDW) values can be used as diagnostic markers in cranial meningiomas. Materials and Methods: The study included results of 29 patient and 47 healthy contributors. Based on pathologies, the patients were divided into two groups. The first group included meningioma patients and the second one included healthy individuals. Healthy contributors named control group. Platelet count and platelet indices were determined using Sysmex XN 550 haematology analyzer. The preoperative platelet count (PLT) and platelet indices included mean platelet volume (MPV), platecrit (PCT), platelet distribution width  (PDW) values were recorded from the routine laboratory tests. Results: There was no statistically significant difference in PLT between the meningioma and healthy groups (p = 0.217). There was a statistically significant difference in PCT between the meningioma group and the healthy group (p = 0.002). There was a statistically significant difference in PDW between meningioma group and healthy group (p = 0.001). In terms of MPV, there was a statistically significant difference between meningioma group and the healthy group (p = 0.001) Conclusion: Platelet count and indices are easily available in the routine blood tests. Despite the retrospective design and small sample size, our findings suggest that altered MPV, PDW and PCT levels might serve as potential biomarkers for the diagnosis of meningiomas.
