Economic and humanistic burden in kidney transplant rejection: a literature review.

Introduction: Antibody-mediated rejection (ABMR) is a major cause of late kidney allograft failure, but its economic and humanistic impacts have not been well-characterized in the literature.

Areas Covered: We reviewed available literature on economic burden (costs and healthcare resource use) and humanistic burden (health-related quality of life impacts [HRQOL] and utility estimates) in patients diagnosed with kidney transplant rejection; ABMR-specific studies were of particular interest. In total, 21 publications reporting economic and humanistic burden were included in the review; 9 of these reported ABMR-specific outcomes.

Clinical and Economic Burden Associated With Acute Graft-Versus-Host Disease After Allogeneic Hematopoietic Cell Transplantation in Germany.

Background: Acute graft-vs-host disease (aGVHD) is a serious complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), yet there are limited data on the clinical and economic burden of aGVHD in Germany. This real-world study aimed to evaluate clinical and economic outcomes among patients in Germany with or without aGVHD after allo-HSCT.

Methods: This retrospective cohort study used administrative claims extracted from the German statutory health insurance database.

Clinical and economic burden associated with graft-versus-host disease following allogeneic hematopoietic cell transplantation in France.

The real-world clinical and economic burden of graft-versus-host disease (GVHD) following allogeneic hematopoietic stem cell transplantation has not been comprehensively studied in France. Clinical outcomes, healthcare resource utilization and costs associated with acute GVHD (aGVHD), chronic GVHD (cGVHD), acute plus chronic GVHD (a+cGVHD) versus no GVHD were compared using French administrative claims data. After propensity score matching, 1934, 408, and 1268 matched pairs were retained for the aGVHD, cGVHD, and a+cGVHD cohorts, respectively.

Rorc restrains the potency of ST2+ regulatory T cells in ameliorating intestinal graft-versus-host disease.

Soluble stimulation-2 (ST2) is increased during graft-versus-host disease (GVHD), while Tregs that express ST2 prevent GVHD through unknown mechanisms. Transplantation of Foxp3- T cells and Tregs that were collected and sorted from different Foxp3 reporter mice indicated that in mice that developed GVHD, ST2+ Tregs were thymus derived and predominantly localized to the intestine. ST2-/- Treg transplantation was associated with reduced total intestinal Treg frequency and activation.

The vimentin intermediate filament network restrains regulatory T cell suppression of graft-versus-host disease.

Regulatory T cells (Tregs) are critical for maintaining immune homeostasis. However, current Treg immunotherapies do not optimally treat inflammatory diseases in patients. Understanding the cellular processes that control Treg function may allow for the augmentation of therapeutic efficacy.
