Vasculitis alérgica fatal asociada con el celecoxib
Lancet (London, England)
|March 19, 2002
Resumen
Una rara reacción adversa al celecoxib, un inhibidor de la COX-2, condujo a una insuficiencia orgánica fatal en un adulto sano, probablemente debido a una vasculitis alérgica. Esto pone de relieve los posibles efectos secundarios graves de los medicamentos antiinflamatorios no esteroideos.
Área de la Ciencia:
- Farmacología Farmacología.
- Toxicología Toxicología.
- Inmunología Inmunología.
Sus antecedentes:
- Celecoxib es un inhibidor selectivo de la ciclooxigenasa-2 (COX-2) utilizado para la inflamación.
- Los antiinflamatorios no esteroideos (AINE) pueden tener efectos adversos.
- Comprender las reacciones farmacológicas raras es crucial para la seguridad del paciente.
Objetivo del estudio:
- Para reportar una rara y fatal reacción adversa a celecoxib.
- Para investigar los posibles mecanismos detrás de este evento imprevisto.
Principales métodos:
- Informe de caso de un paciente adulto previamente sano.
- Análisis de la presentación clínica y presuntos factores etiológicos.
Principales resultados:
- El paciente experimentó insuficiencia aguda múltiple de órganos aguda fatal.
- Se presume que la reacción fue vasculitis alérgica difusa con púrpura.
- Se plantearon dos posibles mecanismos: alergia química directa o desequilibrio endotelial de los eicosanoides.
Conclusiones:
- Celecoxib puede estar asociado con eventos adversos raros, graves e impredecibles.
- Se justifica una mayor investigación sobre la vasculitis y la trombosis inducidas por medicamentos.

Overview
01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
