Resumen
Los pacientes con asma severa con frecuencia tienen hernia de hiato y reflujo gastroesofágico, lo que sugiere la aspiración de ácido gástrico como causa. El tratamiento dirigido al reflujo puede mejorar significativamente los síntomas del asma.
Área de la Ciencia:
- Gastroenterología y Gastroenterología.
- Pulmonología Pulmonología.
- Imágenes médicas de imágenes médicas.
Sus antecedentes:
- El asma grave a menudo presenta desafíos para identificar las causas subyacentes y los tratamientos efectivos.
- La enfermedad de reflujo gastroesofágico (ERGE) y la hernia de hiato son afecciones comunes que pueden afectar los síntomas respiratorios.
Objetivo del estudio:
- Para investigar la prevalencia de la hernia de hiato y el reflujo gastroesofágico en pacientes con asma grave.
- Explorar el vínculo potencial entre la aspiración de ácido gástrico y las exacerbaciones graves del asma.
Principales métodos:
- Análisis retrospectivo de 28 pacientes con asma severa sometidos a exámenes de rayos X de la parte superior gastrointestinal (IGU).
- Comparación de las tasas de prevalencia con una población de control.
Principales resultados:
- Se observó una prevalencia significativamente mayor de hernia de hiato (64%) y reflujo gastroesofágico (46%) en pacientes con asma grave en comparación con los controles (19% y 5%, respectivamente; P < .001).
- Estos hallazgos indican una fuerte asociación entre estas anomalías del tracto gastrointestinal superior y el asma grave.
Conclusiones:
- La aspiración de ácido gástrico debido a la hernia de hiato y la ERGE es un desencadenante frecuente, a menudo pasado por alto, para el asma grave.
- Se recomienda el cribado de rutina para estas afecciones en pacientes con asma resistente al tratamiento.
- Las intervenciones médicas o quirúrgicas dirigidas al reflujo pueden conducir a mejoras sustanciales en el control del asma.

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...

The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.
01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...
01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:25Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...
01:11Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
