Liannv Qiu, Yonglie Zhou, Qinhua Yu, Sujie Zheng, Zhenni Wang, Qiang Huang
Chronic lymphocytic leukaemia (CLL) is characterized by an abnormal expansion of mature B cells with variable progression. Follicular T helper (Tfh) cells help B cells differentiate into plasma cells or long-lived memory B cells in germinal centres (GCs). However, the role of Tfh cells in CLL is poorly understand, and whether it plays a critical role in disease progression in vivo is lacking. In this study, we investigate the dynamic change of circulating Tfh cells in peripheral blood from patients with CLL during the treatment periods to evaluate their utility to predict disease progression...

We describe a rare case of severe autoimmune haemolytic anaemia (AIHA) in the setting of underlying chronic lymphocytic leukaemia receiving intravenous immunoglobulin, history of warm IgG autoantibody and treatment with nivolumab for advanced non-small cell lung cancer. In this report, we describe AIHA as a potential serious immune-related adverse event from immune checkpoint inhibitors, discuss other potential contributing factors and review previously described cases of AIHA in patients receiving programmed death 1 (PD-1) inhibitors...

Cytokinesis failure leads to the emergence of tetraploid cells and multiple centrosomes. Chronic lymphocytic leukaemia (CLL) is the most common haematological malignancy in adults and is characterized by clonal B cell expansion. Here, we show that a significant number of peripheral blood CLL cells are arrested in cytokinesis and that this event occurred after nuclear envelope reformation and before cytoplasmic abscission. mRNA expression data showed that several genes known to be crucial for cell cycle regulation, checkpoint and centromere function, such as ING4, ING5, CDKN1A and CDK4, were significantly dysregulated in CLL samples...

The Bruton tyrosine kinase inhibitor ibrutinib (IB) has attained an important role in the treatment of patients with chronic lymphocytic leukaemia, mantle cell lymphoma, and Waldenström macroglobulinemia, significantly improving clinical outcomes. However, IB therapy has been associated with an increased risk of atrial fibrillation (AF) and bleeding. We report on the expert opinion that a group of Italian haematologists, cardiologists, and pharmacologists jointly released to improve the practical management of patients at risk for AF and bleeding during treatment with IB...

Pathological or spontaneous splenic rupture is a rare but well-recognised complication of haematological malignancies. The authors present a clinical report of a 78-year-old woman with known clinical history of chronic lymphocytic leukaemia and atrial fibrillation under anticoagulation with apixaban which has spontaneous splenic rupture. Pathological examination revealed lymph node and splenic infiltration due to chronic lymphocytic leukaemia. The diagnosis of splenic rupture must be considered in all patients with haematological malignancies who experience acute abdomen...

Inhibitors of anti-apoptotic proteins of the BCL2 family can successfully restart the deregulated process of apoptosis in malignant cells. While non-selective agents have been limited by their affinity to different BCL2 members, and thus inducing excessive toxicity, the highly selective BCL2 inhibitor, venetoclax (ABT-199, Venclexta™), has an acceptable safety profile. To date, it has been approved in monotherapy for the treatment of relapsed or refractory chronic lymphocytic leukaemia (CLL) with 17p deletion...

Important advances in understanding the pathogenesis of chronic lymphocytic leukaemia in the past two decades have led to the development of new prognostic tools and novel targeted therapies that have improved clinical outcome. Chronic lymphocytic leukaemia is the most common type of leukaemia in developed countries, and the median age at diagnosis is 72 years. The criteria for initiating treatment rely on the Rai and Binet staging systems and on the presence of disease-related symptoms. For many patients with chronic lymphocytic leukaemia, treatment with chemotherapy and anti-CD20 monoclonal antibodies is the standard of care...

BACKGROUND: Umbralisib (TGR-1202) is a novel next-generation inhibitor of phosphatidylinositol 3-kinase (PI3K) isoform p110δ (PI3Kδ), which is structurally distinct from other PI3Kδ inhibitors and shows improved isoform selectivity. Umbralisib also uniquely inhibits casein kinase-1ε, a major regulator of protein translation. The aim of this first-in-human phase 1 study was to establish the safety and preliminary activity profile of umbralisib in patients with haematological malignancies...

Immune dysfunction attributed to hypogammaglobulinaemia is common in chronic lymphocytic leukaemia (CLL) and infection is a major contributor to morbidity and mortality. A higher incidence of multiple immunoglobulin and immunoglobulin G (IgG) subclass deficiency was associated with more advanced disease (P < 0·001 and P < 0·001, respectively) in a cohort of 147 CLL patients. Multiple immunoglobulin and IgG subclass deficiency were significantly associated with shorter treatment-free survival (TFS) (P < 0·001 and P = 0·006, respectively)...

T-cell large granular lymphocytic leukaemia (T-LGLL) is a clinically indolent mature T-cell neoplasm characterized by a monoclonal population of CD3+ CD8+ cytotoxic T cells, which usually presents as neutropenia, anaemia and thrombocytopenia. Chronic myelomonocytic leukaemia (CMML) is a clonal haematopoietic disorder with features of both a myeloproliferative neoplasm and myelodysplastic syndrome (MDS). Patients with CMML exhibit a persistent peripheral blood monocytosis in addition to myelodysplastic features...

Herpes simplex virus (HSV) adenitis is a rare but important cause of morbidity in immunocompromised patients. Chronic lymphocytic leukaemia (CLL)/Small lymphocytic lymphoma (SLL) is an indolent disease which impairs the cellular and humoral immunity, predisposing patients to a myriad of infections. Clinically, herpetic adenitis can mimic large cell (Richter's) transformation in patients with CLL. To date, less than 30 cases of HSV adenitis have been reported in the literature. We report a case of a patient with CLL with no prior history of HSV infection, who presented with rapidly enlarging lymph nodes after initial response to idelalisib raising the suspicion of Richter's transformation...

OBJECTIVES: This study was conducted to investigate the real-world effectiveness and tolerability of rituximab-containing chemoimmunotherapies, which have become the standard of care for chronic lymphocytic leukaemia (CLL), particularly for physically fit patients. Furthermore, current treatment patterns in clinical practice were documented, and an unselected real-life population was compared with older, comorbid patients. METHODS: Prospective, multicentre, observational, study with rituximab-containing chemoimmunotherapy in CLL patients...

BACKGROUND: We report a fatal case of disseminated adenovirus infection in a non-transplant haematology adult patient with chronic lymphocytic leukaemia who had completed combination chemoimmunotherapy a few months before developing respiratory symptoms. In such non-transplant patients, monitoring for adenovirus in the blood is not routine. However, with adenoviruses, when there is a more peripheral (i.e. non-blood) site of infection such as the chest, serial adenovirus monitoring in blood for the duration of that illness may be warranted...

Chronic lymphocytic leukaemia (CLL) is a heterogeneous B-cell cancer exhibiting a wide spectrum of disease courses and treatment responses. Molecular characterisation of RNA and DNA from CLL cases has led to the identification of important driver mutations and disease sub-types, but the precise mechanisms of disease progression remain elusive. To further our understanding of CLL biology we performed isobaric labelling and mass spectrometry proteomics on 14 CLL samples, comparing them with B-cells from healthy donors (HDB)...

Chromosome abnormalities detected during cytogenetic investigations for B-cell malignancy offer prognostic information that can have wide ranging clinical impacts on patients. These impacts may include monitoring frequency, treatment type and disease staging level. The use of the synthetic oligonucleotide DSP30 combined with interleukin 2 (IL2) has been described as an effective mitotic stimulant in B-cell disorders, predominantly in chronic lymphocytic leukaemia (CLL) but also a range of other B-cell malignancies...

Ibrutinib is indicated in Europe for the treatment of several B-cell malignancies, including chronic lymphocytic leukaemia (CLL). However, despite the high efficacy and favourable toxicity profile of ibrutinib, recent data suggest that it is not always administered optimally in clinical practice, with an increased tendency for dose reduction and a higher frequency of discontinuation. An expert panel of European haematologists was convened to identify practical issues pertinent to physicians involved in the therapeutic management of ibrutinib-treated CLL patients and here we outline the findings...

Chronic lymphocytic leukaemia (CLL) is the most common B-cell malignancy with a variable clinical outcome. Biomarkers of CLL progression are required for optimising prognosis and therapy. The Inhibitor of Bruton's tyrosine kinase-isoform α (IBTKα) gene encodes a substrate receptor of Cullin 3-dependent E3 ubiquitin ligase, and promotes cell survival in response to the reticulum stress. Searching for novel markers of CLL progression, we analysed the expression of IBTKα in the peripheral blood B-cells of CLL patients, before and after first line therapy causing remission...
