La migraña es una enfermedad alérgica a los alimentos
Lancet (London, England)
|September 29, 1984
Resumen
Los pacientes con migraña severa encontraron alivio con cromoglicato de sodio, lo que sugiere que las alergias alimentarias desencadenan sus síntomas. Este estudio confirma un mecanismo de hipersensibilidad en los casos de migraña refractaria a los medicamentos.
Área de la Ciencia:
- Inmunología Clínica Inmunología Clínica.
- Neurología Neurología.
- Gastroenterología y Gastroenterología.
Sus antecedentes:
- La migraña es una condición neurológica debilitante.
- Los casos graves de migraña a menudo resultan refractarios a las terapias farmacológicas convencionales.
- Las reacciones de hipersensibilidad inducidas por alimentos están implicadas en algunas patologías de la migraña.
Objetivo del estudio:
- Para identificar los desencadenantes de alimentos específicos para la migraña severa.
- Para investigar la eficacia del cromoglicato de sodio en la prevención de la migraña provocada por los alimentos.
- Explorar el papel de los mecanismos de hipersensibilidad y la formación de complejos inmunológicos en la migraña.
Principales métodos:
- Identificación de los provocantes de los alimentos en 9 pacientes con migraña severa y refractaria a los medicamentos.
- Estudio doble ciego controlado con placebo en el que se administró cromoglicato de sodio o placebo por vía oral.
- Monitoreo de los síntomas de la migraña y la presencia de complejos inmunológicos.
Principales resultados:
- El cromoglicato de sodio demostró un efecto protector significativo contra la migraña provocada por los alimentos.
- El fármaco prevenía el mecanismo de hipersensibilidad subyacente a los síntomas de la migraña.
- No se observó la formación de complejos inmunes en pacientes protegidos por cromoglicato de sodio.
Conclusiones:
- Las reacciones alérgicas a los alimentos son una causa confirmada de migraña en esta cohorte de pacientes.
- El cromoglicato de sodio es eficaz en la prevención de la migraña provocada por la hipersensibilidad a los alimentos.
- Esto pone de relieve el potencial de dirigirse a las vías de hipersensibilidad para el tratamiento de la migraña.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:30Other Disorders of Digestive System
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...
01:23Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:24Chronic Pancreatitis I: Introduction
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:25Peptic Ulcer Disease III: Clinical Manifestations and Complications
Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...
01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
