Modulatory Effect of the Euro-Lupus Low-Dose Intravenous Cyclophosphamide Regimen on Circulating Immune Cells in Systemic Lupus Erythematosus.

A Euro-Lupus regimen of low-dose intravenous cyclophosphamide (CFA) is commonly used to treat severe organ manifestations of systemic lupus erythematosus (SLE), particularly lupus nephritis (LN). There are no data on the distributions and dynamics of immune cell populations in patients with various treatment outcomes. The circulating immune cells of 11 female SLE patients were assessed before and after Euro-Lupus regimen (cumulative dose of 3000 mg CFA) by flow cytometry together with those of 16 healthy women.

Dynamic changes in HLA-DR expression during short-term and long-term ibrutinib treatment in patients with chronic lymphocytic leukemia.

There is the first evidence of changes in the kinetics of B cell antigen receptor (BCR) internalisation of neoplastic cells in chronic lymphocytic leukemia (CLL) after the short-term and long-term administration of ibrutinib. We aimed to assess the influence of short-term and long-term ibrutinib treatment on the HLA-DR expression on CLL cells, T cells and monocytes. The immunophenotyping of CLL and immune cells in peripheral blood was performed on 16 high-risk CLL patients treated with ibrutinib.

Neutrophils in chronic lymphocytic leukemia are permanently activated and have functional defects.

A growing body of studies highlights involvement of neutrophils in cancer development and progression. Our aim was to assess the phenotypic and functional properties of circulating neutrophils from patients with chronic lymphocytic leukemia (CLL). The percentage of CD54+ and CD64+ neutrophils as well as CD54 expression on these cells were higher in CLL patients than in age-matched healthy controls.
