Autologous Hematopoetic Stem Cell Transplantation for Refractory Crohn Disease: A Randomized Clinical Trial.

Importance: Case reports and series suggest hematopoietic stem cell transplantation (HSCT) may benefit some patients with Crohn disease.

Objective: To evaluate the effect of autologous HSCT on refractory Crohn disease.

Design, Setting, And Participants: Parallel-group randomized clinical trial conducted in 11 European transplant units from July 2007 to September 2011, with follow-up through March 2013.

Second allogeneic stem cell transplant for aplastic anaemia: a retrospective study by the Severe Aplastic Anaemia Working Party of the European Society for Blood and Marrow Transplantation.

We analysed the outcome of a second allogeneic haematopoietic stem cell transplant (alloHSCT) in 162 patients reported to the European Society for Blood and Marrow Transplantation between 1998 and 2009. Donor origin was a sibling in 110 and an unrelated donor in 52 transplants, respectively. The stem cell source was bone marrow in 31% and peripheral blood in 69% of transplants.

Confirmation of a founder effect in a Northern European population of a new β-globin variant: HBB:c.23_26dup (codons 8/9 (+AGAA)).

β-Thalassemia is a genetic disease caused by a defect in the production of the β-like globin chain. More than 200 known different variants can lead to the disease and are mainly found in populations that have been exposed to malaria parasites. We recently described a duplication of four nucleotides in the first exon of β-globin gene in several families of patients living in Nord-Pas-de-Calais (France).

[How to handle unexpected biological abnormalities observed in the pre-donation workup for hematopoietic stem cell transplantation: an SFGM-TC report on pre-transplant positive pregnancy test and monoclonal gammapathy].

In the attempt to harmonize clinical practices between different French transplantation centers, the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC) set up the third annual series of workshops which brought together practitioners from all member centers and took place in October 2012 in Lille. Here we report our results and recommendations regarding the management of common issues related to the donor: pre-transplant pregnancy and monoclonal gammopathy.
