Introduction.Acute gangrenous appendicitis (AGA) is a common medical condition; however, the grade of appendicitis usually cannot be established preoperatively. We have attempted to identify some indicators, such as the mean platelet volume (MPV) and the platelet distribution width (PDW), to diagnose AGA.Aims.To evaluate whether or not the MPV and PDW are suitable markers to diagnose AGA.Methods.A retrospective study of 160 patients with AGA and 160 healthy patients was undertaken. Disease diagnosis was confirmed based on the pathologic examination of surgical specimens. Patient white blood cell (WBC) count, neutrophil ratio (NR), platelet (PLT) count, MPV, PDW, and hematocrit (HCT) were analyzed. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of these indices in AGA.Results.There were no significant differences between the AGA and control groups in age and gender. Compared to the control group, the WBC count, NR, and PDW were significantly higher (P<0.001, resp.) and the MPV and HCT were significantly lower (P<0.001, resp.) in the AGA group. The diagnostic specificities of the WBC count, NR, PLT count, MPV, PDW, and HCT were 86.3%, 92.5%, 58.1%, 81.7%, 83.9%, and 66.3%, respectively. Therefore, the NR had the highest diagnostic specificity for the diagnosis of AGA.Conclusions.This is the first study to assess the MPV and PDW in patients with AGA. Our present study showed that the MPV is reduced and the PDW is increased in patients with AGA; the sensitivity of PDW was superior to the MPV. A decreased MPV value and an increased PDW could serve as two markers to diagnose AGA. The NR had the highest specificity for the diagnosis of AGA.

Abstract: Symptoms and findings in acute perforated appendicitis (APA) may not always typical in children, becomes difficult to establish the diagnosis preoperatively. Rapid and accurate diagnosis is important to reduce the risk of sepsis and even death. Another biomarkers for diagnosis are needed. This study investigated the diagnostic accuracy of indicators of platelet activation, namely mean platelet volume and platelet distribution width, in children with non perforated acute appendicitis (NPAA) and APA. This retrospective study compared 15 patients with APA (Group I), 15 patients with NPAA (Group II) between January 2016 to December 2018. Patient white blood cell (WBC) count, platelet (PLT) count, MPV, PDW, and hematocrit (HCT) were analyzed. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of these indices in AP. Positive correlation was found between MPV and the degree of AP; as well as negative correlation between  PDW and degree of AP. This is the first study to assess the MPV and PDW in pediatric patients with AP. This study showed the MPV is reduced and the PDW is normal in patients with AP. A decreased MPV value could serve as a marker to diagnose AP preoperatively. More studies are needed to establish relationship between PDW and MPV with AP. Keywords: Appendicitis perforations; Mean Platelet Volume; Platelet distribution width

Purpose:The aim of this article is to determine and compare the platelet activation by three main platelet activation parameters: mean platelet volume, platelet distribution width, and plateletcrit in patients with central retinal vein occlusion and control subjects.Methods:This study included 30 patients with nonischemic central retinal vein occlusion and 30 control subjects. The levels of mean platelet volume, platelet distribution width, and plateletcrit were measured in all groups.Results:The mean serum level of mean platelet volume was 10.01 ± 0.89 fl in central retinal vein occlusion group and 8.74 ± 1.45 fl in control group. The mean serum level of platelet distribution width was 14.31 ± 1.49% and 11.65 ± 1.81% in central retinal vein occlusion group and control group, respectively. Mean serum plateletcrit value was 0.27 ± 0.07% in central retinal vein occlusion group and 0.23 ± 0.07% in control group. Mean platelet volume, platelet distribution width, and plateletcrit levels were significantly higher in central retinal vein occlusion patients than controls ( p < 0.05).Conclusion:Subclinical platelet activation reflected by mean platelet volume, platelet distribution width, and plateletcrit may have an impact on the genesis of vessel occlusion in central retinal vein occlusion. The results may be important for the clinical management of patients with central retinal vein occlusion.

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.

BACKGROUND: The occurrence and early management of acute appendicitis among children are especially important due to the difficult diagnosis and nonspecific symptoms of the disease. Diagnosis of appendicitis in children is very difficult due to similarity of its symptoms to other diseases, and also its self-limiting nature Platelet indexes such as mean platelet volume (MPV) and platelet distribution width (PDW) have been suggested as a biomarker of inflammation. AIM: Therefore, we examined the association of MPV and PDW with acute appendicitis in children. METHODS: This cross-sectional study was conducted on 464 patients with suspected acute appendicitis under the age of 18 years referred to the specialised hospitals of the ten studied provinces between October 2014 and October 2015. All data obtained regarding patient's lab tests, i.e. platelet count, MPV and PDW and also radiological studies and surgical reports were gathered in datasheets and analysed to evaluate the potential association of platelet levels, mean platelet volume (MPV) and platelet distribution width (PDW) with acute appendicitis RESULTS: Our results showed that the MPV was significantly higher in acute appendicitis in comparison to perforated appendicitis as well as acute gangrenous appendicitis. PDW was significantly higher in acute appendicitis in comparison to perforated appendicitis and acute gangrenous appendicitis. The current project indicated that PDW < 10.05 had a sensitivity of 35% and specificity of 75%, platelet count < 229500 had a sensitivity of 24% and specificity of 75% and MPV < 8.95 had a sensitivity of 70% and specificity of 71%. CONCLUSION: Our study suggested that platelet indexes such as MPV and PDW could significantly correlate with acute appendicitis in pediatric patients. Hence, we believe that both MPV and PDW could use as a simple and low-cost lab test for diagnosing acute appendicitis. Also, this study revealed that the MPV lower than 8.95 could be a novel index for diagnosing acute appendicitis with sensitivity of 70% and specificity of 71%.

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.
