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...

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...
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...
Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
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...

Resumen
Este resumen es generado por máquina.

El trasplante de células hemopoyéticas (TCH) puede conducir a la enfermedad del injerto contra el huésped (GVHD), una complicación grave que afecta a múltiples órganos. Esta revisión cubre las causas de la GVHD, la fisiopatología y las estrategias de manejo para los pacientes trasplantados.

Área de la Ciencia:

  • Hematología Hematología.
  • Inmunología Inmunología.
  • Medicina del trasplante Medicina del trasplante.

Sus antecedentes:

  • El trasplante de células hemopoyéticas (TCH) es un tratamiento crítico para malignidades hematológicas de alto riesgo y trastornos genéticos.
  • La enfermedad del injerto contra el huésped (GVHD, por sus siglas en inglés) es una complicación inmunológica importante después de la TCH, que afecta a varios órganos.
  • Un número cada vez mayor de pacientes requiere inmunosupresión continua después de la ECH, lo que aumenta los riesgos de infecciones y otras complicaciones.

Objetivo del estudio:

  • Revisar la comprensión actual de los factores de riesgo y las causas de GVHD.
  • Explorar las redes celulares y de citoquinas involucradas en la fisiopatología de la GVHD.
  • Para resumir las estrategias de prevención, tratamiento y atención de apoyo para GVHD.

Principales métodos:

  • Revisión de la literatura sobre los factores de riesgo, la fisiopatología y el manejo de la GVHD.
  • Análisis de las vías celulares y de citoquinas en GVHD.
  • Síntesis de la evidencia actual sobre la prevención, el tratamiento y la atención de apoyo.

Principales resultados:

  • La GVHD involucra complejos mecanismos inmunológicos que afectan el tracto gastrointestinal, el hígado, la piel y los pulmones.
  • La terapia inmunosupresora post-HCT aumenta la vulnerabilidad a las infecciones.
  • La gestión efectiva requiere un enfoque multifacético que incluya prevención, tratamiento y atención de apoyo.

Conclusiones:

  • Comprender la fisiopatología de la GVHD es crucial para desarrollar mejores estrategias terapéuticas.
  • Los planes de gestión integrales son esenciales para mejorar los resultados en los receptores de HCT.
  • La investigación continua en GVHD es vital para el avance de la medicina de trasplante.
