We examined the effects of glucocorticoids on peripheral blood lymphocytes (PBL) in lymphoproliferative conditions associated with bovine leukemia virus (BLV): persistent lymphocytosis (PL) and lymphosarcoma cell leukemia (BLSL). The effects of hydrocortisone 21-sodium succinate (HSS) on spontaneous incorporation (SI) and mitogen-stimulated incorporation of radiolabeled-thymidine and the effect...
Blood leukocytes of cattle characterized in terms of bovine leukemia virus (BLV) infection and persistent lymphocytosis (PL) were examined for the presence of lymphocyte subpopulation markers and viral antigens. The percentages of cells with surface and intracytoplasmic immunoglobulin M (IgM) and erythrocyteantibody-rosetting cells agreed closely in all infected cattle. This correlation and the...
The bovine leukemia virus (BLV) is an oncogenic retrovirus that is associated with the development of persistent lymphocytosis (PL) and lymphoma in cattle. While B lymphocytes have been shown to be the primary cellular target of BLV, recent studies suggest that some T lymphocytes and monocytes may be infected by the virus. Because virally altered functions of monocytes and/or T cells could cont...
The Bruton's tyrosine kinase (BTK) inhibitor ibrutinib has outstanding activity in patients with chronic lymphocytic leukemia. Most patients experience lymphocytosis, representing lymphocyte egress from nodal compartments. This resolves within 8 months in the majority of patients, but a subgroup has lymphocytosis lasting >12 months. Here we report a detailed characterization of patients with pe...
The differential diagnosis of absolute lymphocytosis is variegated. In general, reactive (secondary) lymphocytosis can be well differentiated from a lymphoproliferative disease (primary lymphocytosis). Together with correspondent clinical characteristics, an absolute lymphocytosis often suggests a potential diagnosis and the further diagnostic process. Reactive lymphocytosis is usually self lim...
The authors provide a review of current knowledge of lymphocytosis in nonneoplastic conditions. They conclude that the list of major differentials for persistent nonneoplastic lymphocyte expansion in dogs and cats is short and that most of these conditions are relatively uncommon. Persistent lymphocytosis of small, mature, or reactive lymphocytes is most commonly the result of chronic lymphocyt...
We report the case of a boy with hereditary spherocytosis who presented with mild microcytic hypochromic anemia and recurrent leg ulcers that had been present since childhood. Chronic natural killer (NK) cell and B-cell lymphocytosis was detected 1 year after therapeutic splenectomy during investigation of recurrent episodes of neutropenia and persistent lymphocytosis. NK cells proved to be abn...
Hairy B-cell lymphoproliferative disorder (HBLD) is one of chronic polyclonal B-cell lymphocytosis. We report a 47-year-old female Japanese patient diagnosed as having HBLD based on lymphocytosis with hairy cell appearance and characteristic phenotypes including CD11c+ and without B-cell monoclonality. She was a non-smoker and possessed HLA-DR4. She has been closely followed up without treatmen...
