Cellular interactions promoting the in vivo expansion of CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells for maintenance of immune tolerance remain poorly defined. Here we report that mobilized Lin(-)Sca-1(+)c-kit(+) (LSK) hematopoietic progenitor cells (HPCs), unlike medullary hematopoietic stem cells (HSCs), selectively drove the direct, immediate(More)
Stenotrophomonas maltophilia (Sm) pneumonia in immunocompromized hosts is an increasingly common nosocomial infection. Even though resistant to multiple antimicrobials, this gram-negative bacteria usually does not present with a fulminant course leading to a fatal hemorrhagic respiratory infection in neutropenic patients. We report here the case of a(More)
The occurrence of post-transplant lymphoproliferative disorders (PTLDs) after allogeneic haematopoietic stem cell transplantation (allo-HSCT) represents a clinical problem. Pretransplant Epstein-Barr virus serological status and viral load was determined in 21 recipients and 28 control transplanted patients, with (+) and without (-) PTLD, respectively.(More)
A yellow-pigmented rod- to coccoid-shaped coryneform microorganism was isolated from the blood of a patient with acute myeloid leukemia. It was identified by 16S rRNA gene sequencing as a previously undescribed species of Janibacter. The isolate was susceptible to penicillins, aminoglycosides, fluoroquinolones, and glycopeptides.
BACKGROUND Pulmonary arterial hypertension (PAH) is a rare complication of systemic lupus erythematosus (SLE). METHODS We identified all patients with SLE and PAH (SLE-PAH) who were enrolled in the French Pulmonary Hypertension Registry with a diagnosis confirmed by right heart catheterization (RHC). A control group of 101 patients with SLE without known(More)
P ulmonary arterial hypertension (PAH) refers to a spectrum of diseases characterised by a permanent increase in pulmonary vascular resistance leading to right ventricular dysfunction and, ultimately, death [1]. PAH can be idiopathic, familial or associated with a number of conditions or diseases, such as congenital heart disease, portal hypertension, HIV(More)
