ved amino acid residue. G1 mom , a heterozygous carrier, presented with menorrhagia (BS = two). 5 females during the S2 pedigree had been also heterozygous carriers of your variant but only two of these current which has a bleeding diathesis. Conclusions: The GATA-1 p.His289Tyr variant resulted in mild anemia, impaired platelet aggregation and secretion in hemizygous carriers. This is the very first variant found within the GATA-1 C-terminal Zn-finger linked with platelet dysfunction and bleeding.cartridges, light transmission aggregometry, lumi-aggregometry, flow cytometry, mepacrine uptake/release assay, Prothrombin time, Activated partial thromboplastic time, Fibrinogen, Element Assays and Ristocetin Cofactor assay. Patients with coagulation element deficiency or Von Willebrand Disorder have been excluded. Patients with PFD have been included, though patients with no haemostatic defect after comprehensive workup(n = 120) had been taken as controls. Success: Total of 498 patients were incorporated from which 67 had Bernard Soulier Syndrome(BSS), 208 had Glanzmann Thrombasthenia(GT),103 had mild PFD(storage pool defect / signal transduction defect / secretion defect) and 120 patients with no haemostatic defect have been taken as controls. Total, CT on PFA-200 Collagen/Epinephrine had highest sensitivity(98.6 ) and damaging predictive value(NPV)(96 ) as screening device for PFD.

Dave; T. Geevar; J. Mammen; G. Chellaiya; A. Samuel; R. Vijayan; S. Singh; S. Nair Christian Medical University and Hospital, Vellore, India Background: Modified Ivy’s Bleeding time(BT) is lower cost but skillbased, invasive and operator-dependent screening check for platelet perform defects(PFD). Platelet Perform Analyzer-200 (PFA-200) is really a pseudo-physiological process wherein citrated entire blood is drawn at higher shear as a result of a smaller aperture in membrane coated with collagen/epinephrine or collagen/ADP, causing platelet adhesion and aggregation occluding the aperture. Time through the start out of the test until eventually occlusion of your aperture would be the Closure Time(CT). Prolonged CT signifies primary haemostatic defect. Aims: To assess the overall performance of modified Ivy’s BT and PFA-200 CT as screening exams for PFD. Methods: Individuals referred to our institution for bleeding workup from January 2016-January 2021 were integrated just after informed consent. Detailed workup was finished by finish blood count, BT, PFA-200 CT working with Collagen/ADP and Collagen/Epinephrine ADP and Collagen/Epinephrine was maximum(100 ) for identification of GT followed by BSS and least for mild PFDs.(Figure1,2) Estrogen receptor Agonist manufacturer FIGURE 1 Sensitivity of Modified Ivy’s Bleeding Time, Closure Time on PFA-200 Collagen/ADP cartridge (COL/ADP) and Collagen/ Epinephrine cartridge (COL/EPI) for identification of Glanzmann Thrombasthenia (GT), Bernard Soulier Syndrome (BSS), Mild Platelet function defects (PFD) and General platelet function disorders670 of|ABSTRACTdefects and four sufferers with other defects. Platelet count and Platelet Indicate Volume (imply SD) in patients’ complete blood had been 27346 x 103/L and 8.seven fl, respectively. PFA-100 was tested in 36/50 individuals identified to have IPD of which 69 (25) gave abnormal CT. Movement cytometry success examined on patients with GT showed lack of expression of CD41 and CD61 on platelet surface. Conclusions: Our current study revealed that se
