from the bone marrow and have a circulating life span of approximately five days in the dog and 30 hours in the cat1. Thrombocytopaenia (low platelet count; less than 200 × 109/L) is the most common acquired haemostatic disorder of dogs and cats2. Its prevalence is higher in dogs, with an apparent higher
16 maj 2024 · In dogs with thrombocytopenia, increased reticulated platelets may help differentiate ITP from non-immune thrombocytopenia, but not between dogs with primary and secondary ITP.
25 sty 2020 · Canine platelet function studies enhance knowledge of normal and altered hemostasis in dogs and can offer insights into human disorders, which can aid in the development of new therapeutic approaches to certain diseases.
Abstract. Immune thrombocytopenia (ITP) is the most common acquired primary hemostatic disorder in dogs. Immune thrombocytopenia less commonly affects cats but is an important cause of mortality and treatment-associated morbidity in both species. Immune thrombocytopenia remains a diagnosis of exclusion for which diagnostic guidelines are lacking.
Von Willebrand disease should be suspected in animals with clinical signs of a platelet disorder and normal coagulation screening tests (APTT and PT) and adequate platelet counts, long buccal mucosa bleeding time, and prolonged PFA-100 closure times.
Abnormal platelet activity can either lead to bleeding tendencies or inappropriate thrombus formation and can occur secondarily to a wide variety of disease processes, with a range of clinical consequences and severity.
The normal lifespan of platelets in dogs (and presumably other species) is around 5-7 days (Tanaka et al 2002).
