Complex evaluation of serum immunoglobulin levels in patients with chronic lymphocytic leukemia: Significant increase in IgA after first-line chemoimmunotherapy.

Introduction: The impact of chemoimmunotherapy (CIT) on immunoglobulin (Ig) quantities in patients with chronic lymphocytic leukemia (CLL) has not been extensively studied.

Methods: We analyzed Ig levels in 45 stable patients with indolent CLL (without indication for treatment) and 87 patients with progressive disease before first-line treatment. Fifty-five patients were evaluated again after the treatment with CIT.

Idelalisib plus rituximab versus ibrutinib in the treatment of relapsed/refractory chronic lymphocytic leukaemia: A real-world analysis from the Chronic Lymphocytic Leukemia Patients Registry (CLLEAR).

Idelalisib (idela), a phosphatidylinositol 3-kinase inhibitor, and ibrutinib, a Bruton tyrosine kinase inhibitor, were the first oral targeted agents approved for relapsed/refractory (R/R) chronic lymphocytic leukaemia (CLL). However, no randomised trials of idelalisib plus rituximab (R-idela) versus ibrutinib have been conducted. Therefore, we performed a real-world retrospective analysis of patients with R/R CLL treated with R-idela (n = 171) or ibrutinib (n = 244).

COVID-19 in patients with chronic lymphocytic leukemia: a multicenter analysis by the Czech CLL study group.

Patients with chronic lymphocytic leukemia (CLL) have a high risk of poor outcomes related to coronavirus disease 2019 (COVID-19). This multicenter cohort study evaluated the impact of COVID-19 infection on the population of CLL patients in the Czech Republic. Between March 2020 and May 2021, 341 patients (237 males) with CLL and COVID-19 disease were identified.

Chylothorax treatment with thoracic duct embolization.

The authors present a case of a patient with non-traumatic right-sided chylothorax which was successfully treated by thoracic duct embolization. The procedure was performed through the cisterna chyli which was visualised by intranodal lymphography. The coils and acrylic tissue glues were used for embolization.

A comprehensive assessment of lymphocyte subsets, their prognostic significance, and changes after first-line therapy administration in patients with chronic lymphocytic leukemia.

Background: In chronic lymphocytic leukemia (CLL), changes in the peripheral blood lymphocyte subsets play an important role in disease progression and infectious complications. The impact of chemoimmunotherapy (CIT) on these changes has not been extensively studied METHODS: We used multi-color flow cytometry, to prospectively measure absolute and relative numbers of CD4 and CD8 T-cells and their subsets in 45 patients with indolent untreated CLL, 86 patients indicated for first-line treatment, and 34 healthy controls. In 55 patients, we analyzed the impact of CIT RESULTS: CLL patients had a significant increase in most cell populations in comparison to controls.
