Insights

Chronic graft-versus-host disease (GVHD) affects half of allogeneic stem cell transplant patients. Early treatment improves survival, while severe cases have a poor prognosis, often due to infections.

Area of Science:

  • Medicine
  • Immunology
  • Hematology

Background:

  • Chronic graft-versus-host disease (GVHD) is a significant late complication following allogeneic stem cell transplantation.
  • It affects approximately 50% of transplant recipients, manifesting at least 100 days post-transplant.
  • Increased use of peripheral blood stem cells and older recipient age contribute to higher chronic GVHD incidence.

Purpose of the Study:

  • To review the current understanding of chronic GVHD, including its pathophysiology, clinical manifestations, and treatment strategies.
  • To highlight the impact of chronic GVHD on patient survival and quality of life.

Main Methods:

  • Literature review of chronic GVHD, focusing on incidence, risk factors, affected organs, and treatment outcomes.
  • Analysis of standard treatment regimens and their efficacy.

Main Results:

  • Chronic GVHD commonly affects the skin, liver, eyes, and mouth, leading to a severely immunocompromised state.
  • Standard treatment involves cyclosporine and prednisone, with an alternating day regimen showing improved survival and reduced adverse events.
  • Topical therapy is recommended for mild cases.
  • Ten-year survival is approximately 80% for mild chronic GVHD but less than 5% for severe cases.

Conclusions:

  • Chronic GVHD poses a significant challenge in allogeneic stem cell transplantation, with severe forms having a dismal prognosis.
  • Effective management, including early intervention and optimized treatment regimens, is crucial for improving patient outcomes.
  • Infectious complications remain a primary cause of mortality in severe chronic GVHD.

Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
