Lymphocyte immunophenotype in dogs with immune-mediated hematologic disease.

ABSTRACT: Immune-mediated hematologic diseases (IMHD) including immune-mediated hemolytic anemia (IMHA) and immune thrombocytopenia (ITP) can cause severe disease in dogs. The underlying immune system abnormalities associated with these conditions is not known. The hypotheses of this study were that dogs with IMHD would have increased frequencies of CD4+ and CD8 + lymphocytes, decreased frequencies and numbers of T regulatory cells, and increased frequencies of interleukin (IL)-17 + lymphocytes. Fifteen dogs with newly diagnosed IMHA or ITP and 15 healthy control dogs were recruited for this prospective study. Flow cytometry was used to enumerate CD4 + lymphocytes, CD8 + lymphocytes, T regulatory (CD4 + CD25 + Foxp3+) cells, and lymphocytes secreting IL-17 in dogs with IMHD at diagnosis, then 2 and
