A long-term study of patients with chronic natural killer cell lymphocytosis

Chronic natural killer cell lymphocytosis: a descriptive clinical study.

We review the clinical manifestations and long-term outlook of patients with chronic natural killer (NK) cell lymphocytosis. After reviewing more than 1,500 peripheral blood lymphoid flow cytometry reports and molecular genetics data from patients with suspected large granular lymphocyte (LGL) proliferation, we identified 10 patients (median age at diagnosis, 60 years; range, 35 to 76 years; ma...

Clinical and laboratory characteristics of chronic natural killer cell lymphocytosis.

Natural killer or natural killer/T cell lineage large granular lymphocytosis associated with dasatinib therapy for Philadelphia chromosome positive leukemia.

Dasatinib, a dual tyrosine kinase inhibitor, is known to modulate or suppress T-cell activation and proliferation. We report a series of 8 patients who developed chronic peripheral lymphocytosis, identified as natural killer cells or natural killer/T-cells based on their large granular lymphocyte morphologies and CD16(+), CD56(+), CD3(-) or CD3(+) immunophenotypic profiles, out of 18 patients r...

Skin manifestations of patients with chronic renal failure on long-term hemodialysis

Background: There are several reports of different cutaneous manifestations in patients with chronic renal failure (CRF) managed by repeated hemodialysis, in the literature. Objective: This study was conducted to evaluate the prevalence of skin manifestations in patients suffering from CRF who are on long-term hemodialysis. Patients and Methods: The skin manifestations of 108 CRF patients who u...

Persistence of Natural Killer (NK) cell lymphocytosis with hyposplenism without development of leukaemia

BACKGROUND Natural killer (NK) cell lymphocytosis usually has an indolent course and can progress into massive lymphocytosis with development of cytopenias and neoplastic diseases. NK-cells usually express one or more "NK-associated" antigens (CD16, CD56, CD57). Reactive expansions are seen in autoimmune diseases, viral infections, solid tumours and non-Hodgkin's lymphoma.
