Background: Neonatal septicemia is a clinical syndrome characterized by signs and symptoms of infection with or without accompanying bacteremia in the first month of life. Objective of the study was to know the effect of sepsis on platelet counts and their indices.Methods: The study was carried out over a period of one and half year from December 2015 to July 2017 at Sangmeshwar and Basaveshwar hospital attached to M. R. medical college, Kalaburagi. 100 cases were considered for this study after proper screening for complete blood count (CBC), platelet count and their indices like mean platelet volume, platelet distribution width and C-reactive protein (CRP) and blood culture in neonates admitted in our neonatal intensive care unit (NICU) with proven sepsis.Results: A total of 100 neonates with blood culture positive for bacterial cases were considered for the study. Early onset septicaemia (59%) was more common than late onset septicaemia (41%). Out of 100 cases 57% cases had growth of gram negative organisms, 40% had growth of gram positive organisms and 3% had growth of fungal. Tachypnea (27%), lethargy (20%) and refusal of feeds (8%) were the commonest clinical presentation followed by, fever (6%), convulsions (5%) and jaundice (5%). 60% neonates had thrombocytopenia of varying severity. Staphylococcus aureus was the most common organism associated with thrombocytopenia (43.3%). Mean platelet volume (MPV) was high in 85% of cases and platelet distribution width (PDW) was high in 96% of cases.Conclusions: The present study highlights the association of thrombocytopenia, mean platelet volume and platelet distribution width with causative organism in proven neonatal sepsis. Staphylococcus aureus was the most common organism causing thrombocytopenia in our NICU.

In clinical practice it is very important to perform the platelet counts.  The estimation of platelet counts from peripheral blood smears is an accurate method and provides adequate quality assurance in traditional methods as the automated cell counters are not available at all hospital setups especially in rural areas. In modern era use of   automated analyzers based on impedance technology has resulted in   improvement of accuracy and helps in measurement of platelet indices such as Mean Platelet Volume (MPV) Plateletcrit (PCT) and Platelet Distribution Width (PDW). However, both the methods have certain limitations. Platelet counts were estimated on a 5-part Differential Automated Hematology Analyzer and manually on Leishman stained peripheral blood SMEAR. Aims & Objective: 1. This study was conducted to compare platelet counts by peripheral blood  smear method and automated method in patients  attending OPD on routine basis in a mountainous hilly region of  J&k . It also aims to study the relation, if any, between the platelet count (automated) and platelet indices like Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) and to assess the possible role of these parameters in certain defined situations. Materials and methods: A prospective study was conducted in a tertiary care hospital on 200 Ethylene Diamine Tetra Acetic acid (EDTA) anticoagulated blood samples. Samples were evaluated by 5-Part differential automated hematology analyser using impedance counting method and by examination of peripheral blood smear method (PBF). Results: In thrombocytopenic patients, the platelet count assessed by automated analyzer revealed an inverse relation with Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) and showed large granular and giant platelets on PBS. Conclusion: Automated hematology analyzer is essential   for immediate   and accurate complete blood count evaluation but blood samples showing erroneous results or low platelet counts on analyzer should be confirmed on peripheral blood smear. The platelet indices like Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) can point to the underlying pathology especially in cases of thrombocytopenia. Keywords: Automated analyser, Peripheral blood smear, MPV, PDW, large granular platelets.

As pregnancy advances, the Platelet Counts decrease while Mean Platelet Volume and Platelet Distribution Width increase, and these kinds of changes are more evident in severe preeclampsia mothers than in non-severe preeclamptic mothers. Thus, Platelet indices could be used as biomarkers for early diagnosis of severity of preeclampsia.

BACKGROUND We wanted to evaluate the role of platelet indices in differentiating reactive and clonal thrombocytosis. METHODS This is a cross sectional observational study conducted for two years among 150 patients with platelet counts of 5 lac and above. Thrombocytosis and utility of platelet indices like Mean Platelet Volume (MPV), Platelet Distribution Width (PDW) for the differential diagnosis of thrombocytosis were done. RESULTS Out of total 150 cases, 144 (96 %) had reactive thrombocytosis, and 6 (4 %) had clonal thrombocytosis. Infectious aetiology is seen in 64 (42.6 %), tissue injury 35 (23 %), rebound thrombocytosis 22 (14.6 %), anaemia 13 (8.6 %), multiple causes 8 (5.3 %), clonal aetiology 6 (4 %), and inflammatory 2 (1.3 %). Patients with reactive thrombocytosis showed a lower mean platelet volume and platelet distribution width compared to primary thrombocytosis. In reactive thrombocytosis MPV range, 6.0 - 8.0 fl with mean MPV 6.5 fl and PDW ranges from 14.0 - 16.2 % with mean PDW 15.3 %. In clonal thrombocytosis MPV range, 6.9 - 8.5 fl with mean MPV 7.9 fl and PDW range was 15.9 - 17.2 % with mean PDW 16.4 %. CONCLUSIONS On analysing the platelet counts and indices, patients with high counts, low MPV and PDW suggested reactive aetiology and patients with high counts and high MPV and PDW suggested clonal aetiology.

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.

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.
