Impact of minimal residual disease response and of status of disease on survival after blinatumomab in B-cell acute lymphoblastic leukemia: results from a real-life study.

Blinatumomab is a bispecific T-cell engager approved for relapsed/refractory and minimal residual disease positive B-cell Acute Lymphoblastic Leukemia. We conducted a retrospective study evaluating the outcome of Blinatumomab. The impact of clinical and treatment-related variables on cumulative incidence of relapse/progression (CIRP), event-free (EFS) and overall survival (OS) was analyzed.

Combined Inhibition of Bcl2 and Bcr-Abl1 Exercises Anti-Leukemia Activity but Does Not Eradicate the Primitive Leukemic Cells.

Background: The management of Philadelphia Chromosome-positive (Ph+) hematological malignancies is strictly correlated to the use of BCR-ABL1 tyrosine kinase inhibitors (TKIs). However, these drugs do not induce leukemic stem cells death and their persistence may generate a disease relapse. Published reports indicated that Venetoclax, a selective BCL2 inhibitor, could be effective in Ph+ diseases, as BCL2 anti-apoptotic activity is modulated by BCR-ABL1 kinase.

Low content of clonogenic progenitors on day+18 is associated with acute graft-versus-host disease and predicts transplant-related mortality.

A marrow reaction associated with acute-graft-versus-host disease (a-GVHD) has been demonstrated in experimental models; its existence in human transplantation is controversial. The aim of the present study was to investigate whether clonogenic marrow precursors are an early marker for a-GVHD and transplant-related mortality (TRM). We prospectively studied 133 patients for colony-forming units-granulocyte-monocyte (CFU-GM) at day +18/+19 posttransplantation.

Diurnal mouthpiece ventilation and nocturnal non-invasive ventilation versus tracheostomy invasive ventilation in patients with amyotrophic lateral sclerosis.

Background: Respiratory disorders are a major cause of morbidity and mortality in amyotrophic lateral sclerosis (ALS). Current guidelines suggest the provision of noninvasive ventilation (NIV) for symptomatic hypoventilation in patients with ALS. Inspite of these results the proportion of ALS patients on tracheostomy invasive ventilation (TIV) is relatively high.
