Plain-English summary

Two cats were experiencing ongoing vomiting, diarrhea, and weight loss. Tests showed they had a high number of a type of white blood cell called eosinophils, which led to a diagnosis of hypereosinophilic syndrome (a condition where there are too many eosinophils in the body). Despite treatment with chemotherapy and steroids, both cats unfortunately passed away 48 and 91 days after their symptoms first appeared.

Abstract

Two cats showing chronic vomiting, diarrhea and weight loss were found to have leukocytosis with marked eosinophilia. Both cats were diagnosed with hypereosinophilic syndrome by the findings of increased eosinophils and their precursors in the bone marrow, eosinophilic infiltration into multiple organs, and exclusion of other causes for eosinophilia. Although cytoreductive chemotherapy with hydroxycarbamide and prednisolone was performed, these two cats died 48 days and 91 days after the initial presentation.
