After hematopoietic stem cell transplantation (HSCT) T- and B-cell reconstitution from primary lymphoid organs are a prerequisite for an effective early lymphocyte reconstitution and a long-term survival for adult patients suffering from acute leukemia. Here, we asked whether quantification of T cell receptor excision circle, (TREC) and kappa-deleting(More)
BACKGROUND Laparoscopic inguinal hernia surgery is increasingly seen as the superior technique in hernia repair. Compared to open-mesh hernia repair, laparoscopic approaches are often reported to be more cost-effective but incur higher costs for the provider. The objective of this study was to analyze the effect of transabdominal preperitoneal (TAPP) and(More)
Rabbit antithymocyte globulin-Genzyme™ is used to prevent graft-versus-host disease after allogeneic hematopoietic stem cell transplantation. Common disadvantages of treatment are infectious complications. The effects of rabbit antithymocyte globulin-Genzyme™ on thymic function have not been well-studied. Multicolor flow cytometry was used to analyze the(More)
B-cell immune dysfunction contributes to the risk of severe infections after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Delayed B-cell regeneration is found in patients with systemic graft-versus-host disease (GVHD) and is often accompanied by bone marrow (BM) suppression. Little is known about human BM GVHD. We analyzed the(More)
Rabbit antithymocyte globulin (Thymoglobulin(®)) is commonly used as graft-versus-host disease (GvHD) prophylaxis. Since we found similar total CD8 T cell numbers in patients with and without Thymoglobulin(®) therapy within the first six months after allogeneic hematopoietic stem cell transplantation, we have analyzed the reconstitution of the CD8 T cell(More)
BACKGROUND Patients with end-stage renal disease are dependent on chronic renal replacement therapy. Outcomes regarding the clinical benefits of hemodiafiltration (HDF) compared to hemodialysis (HD) have been inconclusive so far. The aim of this systematic review is to evaluate the effect of HDF on all-cause mortality and quality of life compared to HD. (More)
