Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is often complicated by alloreactive donor T-cell-mediated graft-versus-host disease (GvHD). The major polyphenol of green tea, epigallocatechin-3-gallate (EGCG), is an inhibitor of both DNA methyltransferase 1 (DNMT1) and signal transducer and activator of transcription 1 (STAT1), which are essential for induction of GvHD. Thus, in...
Histopathology assessment is crucial for the diagnosis of graft versus host disease (GVHD), as the presence of crypt apoptosis is the cardinal criterion required. However, crypt apoptosis is not limited to GVHD; it also occurs in other conditions such as infection, drug reaction, or inflammatory reactions unrelated to GVHD. To better determine whether the presence of 6 or fewer apoptotic bodies...
In this report we have investigated macrophage (M phi) activity and tumor necrosis factor alpha (TNF-alpha) production during graft-vs.-host disease (GVHD). TNF-alpha production by M phi requires two signals: priming of M phi by interferon followed by triggering of TNF-alpha production and release by lipopolysaccharide (LPS). The state of M phi activation was examined in nonirradiated B6AF1 rec...
Intestinal microbiota disruption is associated with acute gastrointestinal (GI) Graft-versus-Host Disease (GvHD) and poor outcome after allogeneic stem cell transplantation (ASCT). Here, in a retrospective analysis of 200 patients undergoing ASCT at the Regensburg University Medical Center, we assessed the relative expression of Paneth cell antimicrobial peptides (AMPs), Human Defensins (HD) 5 ...
BACKGROUND No plasma biomarkers are associated with the response of acute graft-versus-host disease (GVHD) to therapy after allogeneic hematopoietic stem-cell transplantation. METHODS We compared 12 biomarkers in plasma obtained a median of 16 days after therapy initiation from 10 patients with a complete response by day 28 after therapy initiation and in plasma obtained from 10 patients with...
The purpose of the present study was to evaluate the mixed lymphocyte culture as a predictive assay of acute and chronic graft-versus-host disease (GVHD). We studied 153 patients who received a first bone marrow transplantation from human leukocyte antigen-identical siblings. Acute GVHD was observed in 26 of 128 (20.3%) patients evaluated and chronic GVHD occurred in 60 of 114 (52.6%). One-way ...
background: it is suggested that ha-1 mismatching among hematopoietic stem cell transplanted recipients-donors is associated with acute graft-versus-host disease (agvhd). so the aim of this study was to evaluate ha-1 frequency and examine the correlation between ha-1 disparity and gvhd patients who received transplantation from a hla-identical sibling. samples and methods: the dna was extracted...
مقدمه: پیوند سلول های بنیادی خون ساز (hsct) آلوژنیک درمان با ارزشی برای لوسمی های حاد مقاوم به درمان ، لوسمی های با خطر بالای عود ، سندرم های میلو دیس پلاستیک(mds) و لوسمی میلوئیدی مزمن است. نتیجه hsct به عوامل متعددی از جمله مرحله بیماری، میزان تشابه آنتی ژن لکوسیتی انسان (hla) بین دهنده و گیرنده ، رژیم آماده سازی و وقوع بیماری پیوند علیه میزبان (gvhd) بستگی دارد. مطالعات اخیر نشان داده است که...
Conditioning regimens prior to hematopoietic stem cell transplantation (HSCT) are often accompanied by a period of aplasia characterized severe neutropenia, anemia, and thrombocytopenia. Long-term antibacterial immunosuppressive therapy in patients with graft-versus-host disease (GVHD) exacerbates depression. Colony-stimulating factors, erythropoietins, thrombopoietin receptor agonists used cor...
Multiple myeloma (MM) is the most common indication for autologous hematopoietic stem cell transplantation (HSCT) in North America. Despite occurring in up to 50% of patients undergoing allogeneic HSCT, the incidence of graft-versus-host disease (GVHD) after autologous HSCT is reportedly only 5-20%. Gastrointestinal involvement with graft-versus-host disease (GI GVHD) is a common and serious co...
