BACKGROUND With the advancement of techniques for haematopoietic cell transplantation, the number of transplant survivors is increasing rapidly and so are the chances of chronic graft versus host disease (cGVHD). The ocular manifestations of this disease have not been explored in our local population. This study was conducted to determine the frequency of ocular complications in cases of cGVHD ...
مقدمه: بیماری پیوند علیه میزبان (gvhd) یکی از معضلات اصلی پیوند سلول های بنیادی خونساز آلوژنیک است و همچنین یکی از فاکتورهای مهم مؤثر بر نتیجه پیوند می باشد. یک شیوع افزایش یافته gvhd متعاقب پیوند سلول های بنیادی خون محیطی (pbsc) آلوژنیک مطرح شده است، اگرچه، چگونگی تأثیر این مورد بر روی بقا هنوز به خوبی مشخص نشده است. در این مطالعه، هدف ما ارزیابی تأثیر gvhd حاد (agvhd) و gvhd مزمن (cgvhd) بر ر...
BACKGROUND Intention-to-treat (ITT) is the standard data analysis method which includes all patients regardless of receiving treatment. Although the aim of ITT analysis is to prevent bias due to prognostic dissimilarity, it is also a counter-intuitive type of analysis as it counts patients who did not receive treatment, and may lead to "bias toward the null." As treated (AT) method analyzes pat...
The MHC class I-related chain A (MICA) molecules exist as membrane-bound and soluble isoforms and are encoded by a polymorphic gene. Their genetic and phenotype characteristics have been studied in various pathologic settings but not in the context of hematopoietic stem cell transplantation (HSCT). Here, we evaluated whether MICA-related features namely MICA-129 gene polymorphism, serum levels ...
PURPOSE To report the clinical features and investigate the underlying pathological processes of spontaneous corneal perforation in patients with ocular chronic graft-versus-host disease (cGVHD). METHODS A full ophthalmological evaluation of corneal perforation in four patients with cGVHD was performed. Three of them underwent deep anterior lamellar keratoplasty and samples from two of three ...
Chronic graft-versus-host disease (cGVHD) is considered an autoimmune-like disease mediated by donor CD4(+) T cells, but the origin of the autoreactive T cells is still controversial. In this article, we report that the transplantation of DBA/2 donor spleen cells into thymectomized MHC-matched allogeneic BALB/c recipients induced autoimmune-like cGVHD, although not in control syngeneic DBA/2 re...
We report 28 patients with advanced chronic graft-versus-host disease (cGVHD) treated with extracorporeal photopheresis (ECP). All had failed conventional immunosuppressive therapy. Of the patients, 27 had extensive cGVHD and 20 had more than 50% cutaneous surface area involvement. ECP was initiated approximately 2 years after onsetofcGVHDand3years followingallogeneic stem cell transplantation ...
Human cytomegalovirus (hCMV) infection and its reactivation correlate both with the increased risk and with the worsening of graft-versus-host disease (GVHD). Because scleroderma-like skin lesions can occur in chronic GVHD (cGVHD) in allogeneic stem-cell transplant (HCT) patients and hCMV is relevant in the pathogenesis of systemic sclerosis (SSc), we evaluated the possible pathogenetic link be...
In the DBA/2 --> unirradiated (C57BL/6 x DBA/2)F(1) model of chronic graft-vs-host disease (cGVHD), donor CD4(+) T cells play a critical role in breaking host B cell tolerance, while donor CD8(+) T cells are rapidly removed and the remaining cells fall into anergy. Previously we have demonstrated that in vivo ligation of GITR (glucocorticoid-induced TNF receptor-related gene) can activate donor...
Steroid refractory chronic graft-versus-host disease (cGVHD) is associated with a significant morbidity and mortality. Although first-line treatment of cGVHD is based on controlled trials, second-line treatment is almost solely based on phase II trials or retrospective analyses. The consensus conference on clinical practice in cGVHD held in Regensburg aimed to achieve a consensus on the current...
