Plain-English summary
A group of dogs with immune-mediated hemolytic anemia (a condition where the immune system attacks red blood cells) showed signs of increased platelet activation, especially in those with very low platelet counts. This means that their blood was more likely to form clots, which can lead to serious complications. The study found a strong link between the severity of the low platelet count and the level of platelet activation. Understanding this connection can help veterinarians manage the risks of blood clots in affected dogs.

Abstract
OBJECTIVES: To establish whether heightened platelet activation is a common feature of canine immune-mediated haemolytic anaemia, and to evaluate the hypothesis that platelet activation plays a role in the pathogenesis of thromboembolism. METHODS: Using whole-blood flow-cytometric analysis, the proportion of activated platelets and platelet-leucocyte aggregates in blood samples from 14 dogs with immune-mediated haemolytic anaemia and 14 healthy dogs was calculated. General linear models with binomial errors were used to compare groups. Results from the immune-mediated haemolytic anaemia-affected dogs were then correlated with established risk factors for thromboembolism in canine immune-mediated haemolytic anaemia, D-dimer concentration and antithrombin activity. RESULTS: There was a strong correlation between platelet activation and severe thrombocytopenia, with heightened platelet activation being observed predominantly in severely thrombocytopenic dogs. CLINICAL SIGNIFICANCE: Dogs with immune-mediated haemolytic anaemia, particularly those with concurrent severe thrombocytopenia, are likely to have heightened platelet activation, which may play a role in the pathogenesis of thromboembolism.
