Obinutuzumab plus bendamustine for relapsed/refractory chronic lymphocytic leukemia and predictive and prognostic impact of genetic alterations: the phase II GABRIELL study.

GABRIELL was a phase II single-arm study to evaluate the efficacy and safety of obinutuzumab plus bendamustine for relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). Seventy-two patients with active disease received treatment for up to six 28-day cycles. Overall response rate was 78.

Real-world effectiveness of caplacizumab vs the standard of care in immune thrombotic thrombocytopenic purpura.

Immune thrombotic thrombocytopenic purpura (iTTP) is a thrombotic microangiopathy caused by anti-ADAMTS13 antibodies. Caplacizumab is approved for adults with an acute episode of iTTP in conjunction with plasma exchange (PEX) and immunosuppression. The objective of this study was to analyze and compare the safety and efficacy of caplacizumab vs the standard of care and assess the effect of the concomitant use of rituximab.

Real-World Characteristics and Outcome of Patients Treated With Single-Agent Ibrutinib for Chronic Lymphocytic Leukemia in Spain (IBRORS-LLC Study).

Background: Ibrutinib demonstrated remarkable efficacy and favorable tolerability in patients with untreated or relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL), including those with high-risk genetic alterations. The IBRORS-CLL study assessed the characteristics, clinical management and outcome of CLL patients receiving ibrutinib in routine clinical practice in Spain.

Patients: Observational, retrospective, multicenter study in CLL patients who started single-agent ibrutinib as first-line treatment or at first or second relapse between January 2016 and January 2019.

A critical evaluation of caplacizumab for the treatment of acquired thrombotic thrombocytopenic purpura.

Acquired thrombotic thrombocytopenic purpura (aTTP) is a thrombotic microangiopathy caused by inhibitory autoantibodies against ADAMTS13 protein. Until recently, the combination of plasma exchange (PEX) and immunosuppression has been the standard front-line treatment in this disorder. However, aTTP-related mortality, refractoriness, and relapse are still a matter of concern.

Choroidal lymphoma diagnosed by polymerase chain reaction-based clonality assessment.

Purpose: To report a case of primary choroidal lymphoma that was confirmed by polymerase chain reaction-based clonality testing.

Case Report: A 50-year-old woman presented with unilateral progressive vision loss. Fundus examination and B-ultrasonography demonstrated diffuse choroidal thickening without vitritis.

Therapeutic plasma exchange: Review of current indications.

Therapeutic plasma exchange (TPE) is the extracorporeal technique performed in an apheresis device were patient's plasma is separated from whole blood and removed, while the cellular blood components are returned to the patient together with a replacement fluid. By the extracorporeal removal of pathological substances and the replacement of deficient plasma components, it constitutes an important tool for the management of several disorders and it is a well-known and established treatment for numerous diseases. Additionally, overall available data confirm the safety and efficacy of TPE.

High prognostic value of measurable residual disease detection by flow cytometry in chronic lymphocytic leukemia patients treated with front-line fludarabine, cyclophosphamide, and rituximab, followed by three years of rituximab maintenance.

It has been postulated that monitoring measurable residual disease (MRD) could be used as a surrogate marker of progression-free survival (PFS) in chronic lymphocytic leukemia (CLL) patients after treatment with immunochemotherapy regimens. In this study, we analyzed the outcome of 84 patients at 3 years of follow-up after first-line treatment with fludarabine, cyclophosphamide and rituximab (FCR) induction followed by 36 months of rituximab maintenance thearpy. MRD was assessed by a quantitative four-color flow cytometry panel with a sensitivity level of 10 Eighty out of 84 evaluable patients (95.

Brentuximab vedotin in Hodgkin lymphoma and anaplastic large-cell lymphoma: an evidence-based review.

Hodgkin lymphoma (HL) and anaplastic large-cell lymphoma (ALCL) account for ~10% and 2%-3% of all cases of lymphoid neoplasms, respectively. Up to 30% of patients with HL are refractory or relapse after first-line therapy, and elderly patients with HL represent a subgroup of patients with suboptimal responses to the currently available treatments. Five-year overall survival for ALCL patients is 50%-80% with conventional chemotherapy.

Immunotherapy for the treatment of Hodgkin lymphoma.

Most patients with Hodgkin lymphoma (HL) enjoy durable remissions following front-line treatment but 30% of patients are refractory or relapse after first line therapy. Salvage chemotherapy followed by autologous stem cell transplantation (ASCT) can cure an additional 50-55% of relapsing patients but new treatments are needed for patients with HL who are refractory or relapse after ASCT. Immunotherapy has emerged as a promising treatment for the management of these patients.

Cellular Uptake of Glucocerebrosidase in Gaucher Patients Receiving Enzyme Replacement Treatment.

Background: Enzyme replacement therapy (ERT) is currently the standard treatment for patients with Gaucher disease type I (GD1), but the pharmacokinetics have hardly been studied. This study aimed to quantify in vivo enzyme activity in peripheral leukocytes from patients receiving long-term treatment with imiglucerase or velaglucerase for GD1, and set out to assess the process of enzymatic uptake by peripheral leukocytes.

Methods: A prospective semi-experimental study was conducted.
