The seasonal distribution of immune thrombotic thrombocytopenic purpura is influenced by geography: Epidemiologic findings from a multi-center analysis of 719 disease episodes

Prior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5-year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included. A total of 583 patients experienced 719 iTTP episodes. Significantly more episodes occurred in winter compared to spring and in winter compared to autumn. More cases also occurred in winter compared to summer, but this difference was not statistically significant. Occurrence during winter was most pronounced at sites further from the equator and/or with greater annual temperature variation.

Comparison of prognostic scores according to WHO classification in 170 patients with advanced mastocytosis and C-finding treated with midostaurin

The AdvSM subtypecombined with the MARS score has the best prognostic value for overall survivalin patients with AdvSM and at least one C-finding treated with midostaurin. Thus,five subgroups of AdvSM patients with different outcomes are identified. Thepresence of an abnormal karyotype or portal hypertension is associated with therisk of AML transformation in patients with SM-AHN.

A phase 2 trial of mini-hyper-CVD, blinatumomab, and ponatinib in Philadelphia positive acute lymphoblastic leukemia

Twenty adults with newly diagnosed (ND) or relapsed/refractory (RR) Ph-positive acute lymphoblastic leukemia (ALL), or chronic myeloid leukemia in lymphoid blast phase (CML-LBP), were treated with mini-hyperCVD, ponatinib, and blinatumomab. Complete molecular response was achieved in 78% of ND patients, while CR/CRi was achieved in 100% of RR and CML-LBP. The 3-year overall survival rate was 76% (95% CI, 47%–90%).
