fusion genes in acute leukemias: genetic characterization of rare cases.

Introduction: Alterations of the gene (9q34) are recurrent in acute leukemias. Rearrangements of chromosomal band 9q34 targeting this locus can be karyotypically distinct, for example t(6;9)(p22;q34)/, or cryptic, in which case no visible change of 9q34 is seen by chromosome banding.

Methods: We examined 9 cases of acute leukemia with rearrangement by array Comparative Genomic Hybridization (aCGH), reverse-transcription polymerase chain reaction (RT-PCR), and cycle sequencing/Sanger sequencing to detect which fusion genes had been generated.

Intensifying treatment in PET-positive multiple myeloma patients after upfront autologous stem cell transplantation.

F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET) positivity after first-line treatment with autologous stem cell transplantation (ASCT) in multiple myeloma is strongly correlated with reduced progression-free and overall survival. However, PET-positive patients who achieve PET negativity after treatment seem to have comparable outcomes to patients who were PET negative at diagnosis. Hence, giving PET-positive patients additional treatment may improve their outcome.

Extracorporeal Photopheresis as Graft-versus-Host Disease Prophylaxis: A Randomized Controlled Trial.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the sole curative option for many patients diagnosed with hematologic malignancies. A major obstacle is graft-versus-host disease (GVHD), causing significant morbidity and mortality. Extracorporeal photopheresis (ECP) is an increasingly applied treatment for GVHD, owing in part to its favorable safety profile.

Markers of extracellular matrix remodeling and systemic inflammation in patients with heritable thoracic aortic diseases.

Background: In approximately 20% of patients with thoracic aortic aneurysms or dissections a heritable thoracic aortic disease (HTAD) is suspected. Several monogenic connective tissue diseases imply high risk of aortic disease, including both non-syndromic and syndromic forms. There are some studies assessing inflammation and extracellular matrix remodeling in patients with non-hereditary aortic disease, but such studies in patients with hereditary diseases are scarce.

Interleukin-6 inhibition in ST-elevation myocardial infarction: Immune cell profile in the randomised ASSAIL-MI trial.

Background: We recently showed that interleukin (IL)-6 inhibition by tocilizumab improves myocardial salvage in ST-elevation myocardial infarction (STEMI). However, the mechanisms for this effect are not clear.

Methods: In this exploratory sub-study of the ASSAIL-MI trial, we examined leukocyte differential counts and their relation to myocardial salvage and peak troponin T (TnT) in STEMI patients randomised to tocilizumab (n = 101) or placebo (n = 98).
