Humoral response to mRNA anti-COVID-19 vaccines BNT162b2 and mRNA-1273 in patients with chronic lymphocytic leukemia.

Immunocompromised individuals such as patients with chronic lymphocytic leukemia (CLL) are at risk of impaired immune responses to vaccination. The objective of our study was to evaluate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibody responses in patients with CLL after the first, second, and third doses of the BNT162b2 or mRNA-1273 vaccines and after a single dose for patients with confirmed previous COVID-19. In all, 530 patients were included in the study.

Atrial fibrillation in CLL patients treated with ibrutinib. An international retrospective study.

Atrial fibrillation (AF) occurs in 5-9% of patients treated with ibrutinib for chronic lymphocytic leukaemia (CLL); the clinical consequences and optimal management are unclear. We retrospectively studied 56 CLL patients who received ibrutinib and developed AF. Median time to onset was 3·8 months.

Old DAT and new data: positive direct antiglobulin test identifies a subgroup with poor outcome among chronic lymphocytic leukemia stage A patients.

Only a minority of chronic lymphocytic leukemia (CLL) patients harboring a positive direct antiglobulin test (DAT) will develop autoimmune hemolytic anemia (AIHA). In a single institution cohort of 378 CLL patients, 56 patients (14.8%) had at least one positive DAT during the course of the disease, either at diagnosis or later.

Type I cryoglobulinemia in multiple myeloma, a rare entity: analysis of clinical and biological characteristics of seven cases and review of the literature.

The type I cryoglobulins (CGs) account for 10-15% of all cryoglobulins and are found in patients with hematological disorders. We here describe the largest series of seven cases of type I cryoglobulinemia associated with multiple myeloma (MM) and provide a detailed review of the literature associated with this disorder, with the aim of improving the future diagnosis and therapeutic management of this rare disease. Six of the cases in our series were men aged 28-69 years, and most of the subject patients had an immunoglobulin G (IgG) monoclonal component and stage I indolent MM that manifested as cryoglobulin-related symptoms.

Leukemic phase of follicular lymphomas: an atypical presentation.

Follicular lymphomas (FLs) are frequent B-cell derived malignancies, generally demonstrating an indolent evolution. Although circulating FL cells may be detected by high-resolution analysis, bloodstream involvement by FL cells is unusual. We observed in 10 patients a leukemic phase of FL at the onset of the disease.

Combined ifosfamide, etoposide and oxalipatin chemotherapy, a low-toxicity regimen for first-relapsed or refractory Hodgkin lymphoma after ABVD/EBVP: a prospective monocentre study on 34 patients.

Around 20% of Hodgkin lymphoma (HL) patients are refractory to first-line therapy with ABVD (adriamycin-bleomycin-vinblastine-dacarbazine) or relapse after complete remission. Salvage regimens frequently have delayed courses or require dose-reduction because of haemotoxicity. We evaluated the IVOx (ifosfamide-etoposide-oxaliplatin) salvage regimen in terms of response rate, toxicity and stem-cell mobilization.
