Risk of thromboembolism with thrombopoietin receptor agonists in adult patients with thrombocytopenia: systematic review and meta-analysis of randomi…
2012
Background and objective: Thrombopoietin receptor (TPOr) agonists (romiplostim and eltrombopag) are a new approach for the treatment of thrombocytopenia-associated conditions. They promote megakaryocyte differentiation, proliferation and platelet production. In the European Union, both are orphan drugs with an indication restricted to splenectomized immune thrombocytopenic purpura patients who are refractory to other treatments. Due to increasing platelet counts, these drugs may represent a risk for thromboembolic complications. We analyzed whether TPOr agonists affect thromboembolisms occurrence in adult thrombocytopenic patients. Materials and methods: We conducted a systematic review and…
Infections of the Central Nervous System after Unrelated Donor Umbilical Cord Blood Transplantation or Human Leukocyte Antigen–Matched Sibling Transp…
2016
We analyzed the incidence, clinical characteristics, prognostic factors, and outcome of central nervous system (CNS) infections in consecutive patients with receiving umbilical cord blood transplantation (UCBT) (n = 343) or HLA-matched sibling donor stem cell transplantation (MST) (n = 366). Thirty-four CNS infections were documented at a median time of 116 days after transplantation (range, 7 to 1161). The cumulative incidence (CI) risk of developing a CNS infection was .6% at day +30, 2.3% at day +90, and 4.9% at 5 years. The 5-year CI of CNS infection was 8.2% after UCBT and 1.7% after MST (P .001). The causative micro-organisms of CNS infections were fungi (35%), virus (32%), Toxoplasm…
Kinetics of Torque Teno virus DNA in stools may predict occurrence of acute intestinal graft versus host disease early after allogeneic hematopoietic…
2020
Torque Teno virus (TTV) DNA load in blood may act as a marker of immune competence after allogeneic hematopoietic stem cell transplant recipients (allo-HSCT). Conflicting data have been reported as to the value of this biomarker for anticipating acute Graft-versus-host disease (aGvHD) occurrence. Here, we hypothesized that quantitation of TTV DNA load in stool specimens early after allo-HSCT could be used to identify patients at high risk of acute intestinal graft-versus-host disease (aIGvHD). In this prospective two-center study we recruited a total of 83 non-consecutive adult patients undergoing allo-HSCT. The study period comprised the first 120 days after allo-HSCT. TTV DNA was quantita…

Prospective Randomized Study Comparing Myeloablative Unrelated Umbilical Cord Blood Transplantation versus HLA-Haploidentical Related Stem Cell Trans…
2020
In this prospective randomized study, we compared the outcomes of single-unit umbilical cord blood transplantation (UCBT) and unmanipulated haploidentical stem cell transplantation (haplo-SCT) with post-transplantation cyclophosphamide (PTCy) in adults with hematologic malignancies. All patients received a myeloablative conditioning (MAC) regimen consisting of thiotepa, busulfan, and fludarabine, with antithymocyte globulin (ATG) added for UCBT recipients. Nineteen patients were randomized to UCBT and the other 26 to haplo-HSCT. Four patients (15%) allocated to the haplo-HSCT arm lacked a suitable donor and were crossed over to the UCBT arm. Finally, 23 underwent UCBT and 22 underwent haplo…
Cytomegalovirus DNA load monitoring in stool specimens for anticipating the occurrence of intestinal acute graft‐versus‐host disease following alloge…
2020
Background Data have been published suggesting a bidirectional interaction between cytomegalovirus (CMV) infection and acute graft-versus-host disease (aGvHD) in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients. Here, we hypothesized that prospective CMV DNA monitoring in stool specimens may be useful for predicting subsequent occurrence of intestinal aGvHD (IaGvHD). Methods This two-center study enrolled 121 consecutive adult patients undergoing any modality of allo-HSCT. A total of 1,009 stool specimens were collected (a median of 7 specimens/patient; range, 1-18). CMV DNA monitoring in stools and plasma was performed using real-time PCR assays. Results CMV DNA was det…
Specific challenges in end-of-life care for patients with hematological malignancies.
2019
Purpose of review The disease-related burden of patients with hematological malignancies is comparable with patients suffering from solid tumors. Palliative care offers relief from suffering independent of type of disease and prognosis. The prevalence of hematological malignancies is expected to increase in the next 20 years because of better therapeutic options with longer survival and because of the aging population. However, patients with hematological malignancies are underrepresented in palliative care as these diseases are associated with special care needs and prognostic uncertainty, which differ from the unambiguity of terminally ill patients with solid tumors. This review describes…
Entre forme d'habitat groupé et forme d'habitat dispersé : le cas intermédiaire d'une occupation rurale aux IIIe et IVe siècles ap. J.-C. entre Fragn…
2011
A diagnosis made in 2008 on a zone measuring 98 ha north-east of Chalon-sur-Saône has revealed a lane, a small funerary zone and four occupied areas incorporating buildings used for domestic and agricultural (barn) purposes used during the last two thirds of the 3rd century and the first half of the 4th century ad. The linear distribution of the remains over a distance of 1300 metres has stimulated lively interest and poses several questions regarding the exact nature of the occupation. One of the hypotheses put forward is that of a small agglomeration associated with a possible estate. Analysis relies on studies of ceramic and metallic objects and examination of sets of coins

2008
International audience; Un diagnostic réalisé en 2008 sur une emprise de 98 ha, au nord-est de Chalon-sur-Saône, a mis au jour une voie, une petite zone funéraire, ainsi que quatre aires d’occupation témoignant de la présence de bâtiments à vocation domestique et agricole (grange) occupés des deux derniers tiers du IIIe siècle au milieu du IVe siècle ap. J.-C. La distribution linéaire des vestiges sur une longueur de 1 300 m suscite un vif intérêt et pose plusieurs questions quant à la nature exacte de l’occupation. L’identification d’une petite agglomération associée à un éventuel domaine foncier fait partie des hypothèses retenues. L’analyse s’appuie sur les études du mobilier céramique e…
Tif1γ regulates the TGF-β1 receptor and promotes physiological aging of hematopoietic stem cells.
2014
The hematopoietic system declines with age. Myeloid-biased differentiation and increased incidence of myeloid malignancies feature aging of hematopoietic stem cells (HSCs), but the mechanisms involved remain uncertain. Here, we report that 4-mo-old mice deleted for transcription intermediary factor 1γ (Tif1γ) in HSCs developed an accelerated aging phenotype. To reinforce this result, we also show that Tif1γ is down-regulated in HSCs during aging in 20-mo-old wild-type mice. We established that Tif1γ controls TGF-β1 receptor (Tgfbr1) turnover. Compared with young HSCs, Tif1γ(-/-) and old HSCs are more sensitive to TGF-β signaling. Importantly, we identified two populations of HSCs specifical…
