AIMS An increase in platelet aggregability is associated with unstable angina and myocardial infarction. Platelet size and activity correlate and mean platelet volume was found to be increased before acute myocardial infarction. We measured the mean platelet volume and platelet count in patients with stable angina, unstable angina and non-cardiac chest pain. METHODS AND RESULTS We studied 981...

background crimean-congo hemorrhagic fever (cchf) was a rare disease in iran before 1999. during the last 15 years, it has been reported from different provinces of iran, mostly from southeastern iran. objectives this study aimed to evaluate the factors associated with poor outcome in children and adolescents with cchf. patients and methods we studied all files of children (age < 19 years old) ...

PURPOSE Smoking is a significant risk factor of cardiac ischaemia. Changes in platelet count, morphology and platelet activation enhance the risk. MATERIAL AND METHODS The objective of the study was to assess platelet parameters in smoking healthy subjects with reference to sex. In the group of women, 27% were smokers, in the group of men--49%. All the subjects were tested for platelet count ...

BACKGROUND A relationship between Helicobacter pylori infection and idiopathic thrombocytopenic purpura (ITP) has previously been reported. We determined the prevalence of H pylori infection in Japanese patients with chronic ITP and the effect of its eradication on platelet count. METHODS The study population comprised 53 Japanese adults with chronic ITP and a platelet count of less than 100 ...

BACKGROUND Iron deficiency is common in non-dialysis chronic kidney disease (ND-CKD) patients and, on occasion, requires parenteral iron therapy. We investigated the effect of intravenous iron repletion on platelet counts in ND-CKD patients with and without concomitant darbepoetin administration. METHODS We conducted a retrospective analysis of ND-CKD patients with iron deficiency anemia trea...

The aim of this study was to evaluate the percentage of reticulated platelets in healthy dogs with breed-related thrombocytopenia. Seventy two dogs, clinically healthy, were enrolled in the study. Blood was collected from the patients and anticoagulated with tripotassium ethylenediaminetetraacetic acid (K3-EDTA) and sodium citrate. Platelet count was obtained by an impedance haematology analyse...

Errors in platelet counts result most often in falsely low counts as a consequence of partial clotting of the specimen, ethylene diamine tetracetic acid (EDTA) induced agglutination or platelet satellitism to polynuclear neutrophils. Spuriously elevated platelet counts are less common and may result from the presence of platelet-sized particles such as microcytes, schizocytes, cellular debris, ...

OBJECTIVE Portal pressure gradient (PPG) after transjugular intrahepatic portosystemic shunt (TIPS) <12 mmHg has been reported as the only factor predictive of increase in platelet count. As flow velocities measured on Doppler ultrasound are related to pressure gradient based on the Bernoulli equation, we used this parameter to predict increased platelet count after TIPS placement. METHODS A ...

After stenosis of arteriovenous vascular access in hemodialysis patients, platelets play a crucial role in subsequent thrombus formation, leading to access failure. In a previous study, the mean platelet volume (MPV)/platelet count ratio, but not MPV alone, was shown to be an independent predictor of 4-year mortality after myocardial infarction. However, little is known about the potential infl...
