INTRODUCTION Bone marrow transplantation (BMT) is a treatment option for hematological diseases and immunodeficiency. It is frequently used today. BMT predisposes patients to upper airway infections and its complications, such as rhinosinusitis (RS). Chemotherapy, radiotherapy, viral infections, antibiotic therapy, graft versus host disease (GVHD) are rhinosinusitis predisposing conditions. A...
This study investigated the use of low dose methotrexate (MTX) (5 mg/m2/infusion) for the treatment of graft-versus-host disease (GVHD), after failure of corticosteroids. Twelve patients had refractory acute GVHD, while eight received MTX for severe chronic GVHD and/or the side effects of corticosteroids. Thirteen patients responded to MTX with six complete remissions and little toxicity, sugge...
The complete repertoire of cellular and molecular determinants that influence graft-vs-host disease (GVHD) is not known. Using a well-established murine model of GVHD (B6-->bm12 mice), we sought to elucidate the role of the donor non-T cell compartment and molecular determinants therein in the pathogenesis of GVHD. In this model the acute GVHD-inducing effects of purified B6 wild-type (wt) CD4(...
Graft-versus-host disease (GVHD) commonly occurs when immunocompetent donor cells attack a genetically disparate host. GVHD occurs primarily after allogeneic bone marrow transplantation (BMT) and remains a significant cause of morbidity, thus limiting the efficacy of this treatment. GVHD can exist as two distinct clinical entities: acute (affecting multiple solid organs) and chronic (presenting...
GVHD is a syndrome that results from minor and major histocompatibility complex incompatibilities between the donor and recipient. More than 50 years after its initial description, the pathophysiology of GVHD remains poorly understood. Nonetheless, donor T cells have been shown to be critical to the pathophysiology of acute and chronic GVHD, yet precisely how they function remains unclear. The ...
Chronic graft-versus-host disease (GVHD) is an immune-mediated disorder that occurs frequently after allogeneic hematopoietic cell transplantation (HCT). Most cases are diagnosed within the first year at a median of 4 to 6 months after HCT, but 5-10% of cases are initially diagnosed beyond the first post-transplant year. Chronic GVHD most often involves the skin and mouth, but almost any other ...
There is no standard therapy for steroid-refractory chronic graft-versus-host disease (GVHD). This problem is particularly daunting in children with chronic GVHD, whereby the effects of the disease and its treatment may impair normal growth and development. Children are also particularly vulnerable to failure and/or toxicity of therapy; for example, joint contractures or joint damage may result...
Chronic graft-versus-host disease (GVHD) is a major limitation of successful allogeneic hematopoietic stem cell transplantation (HSCT). Extracorporeal photochemotherapy (ECP) has been tested extensively in small cohorts of patients with chronic GVHD. In this study, we retrospectively evaluated 71 patients with severe chronic GVHD treated with ECP. Response rate was 61% (n = 43), and 14 patients...
Sclerotic chronic graft-versus-host disease (GVHD) can result in disability after allogeneic hematopoietic cell transplantation. We assessed the incidence and risk factors of sclerosis and its association with transplant outcomes among 977 consecutive patients treated with systemic immunosuppression for chronic GVHD. Sclerosis was defined when cutaneous sclerosis, fasciitis, or joint contractur...
Thalidomide has one of the most notorious drug histories because of its teratogenicity. Its widespread use in the 1960s led to a worldwide epidemic of phocomelia in inborns; this in turn led to its complete ban in most of the world. However, it has now been licensed for selected indications including graft-versushost-disease (GVHD) after bone marrow transplantation, wasting associated with tube...
