Irritable Bowel Syndrome I: Introduction

755
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Chronic Bowel Disorders: Introduction

663
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Drugs for Treatment of Diarrhea-Predominant IBS

479
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Inflammatory Bowel Disease I: Ulcerative Colitis

664
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Área de la Ciencia:

  • Gastroenterología
  • Neuro-gastroenterología
  • Trastornos funcionales del tracto gastrointestinal

Sus antecedentes:

  • El síndrome del intestino irritable (IBS) afecta al 5-10% de las personas sanas, presentándose con dolor abdominal y cambios en la forma/frecuencia de las heces.
  • Los factores de riesgo incluyen infección entérica, comorbilidad psicológica y mayor prevalencia en mujeres jóvenes.
  • La fisiopatología implica disfunción del eje intestino-cerebro, lo que lleva a problemas de motilidad, hipersensibilidad visceral y procesamiento alterado del sistema nervioso central.

Objetivo del estudio:

  • Revisar la comprensión actual de la fisiopatología del síndrome del intestino irritable (IBS).
  • Esbozar enfoques de diagnóstico y estrategias de manejo para el SII.
  • Para resaltar el panorama en evolución de los nuevos desarrollos terapéuticos para el SII.

Principales métodos:

  • Revisión de la literatura existente sobre la fisiopatología, el diagnóstico y el tratamiento del SII.
  • Análisis de los factores de riesgo y datos epidemiológicos.
  • Examen de las intervenciones terapéuticas actuales y emergentes.

Principales resultados:

  • El diagnóstico del SII se basa en la historia clínica, con investigaciones juiciosas para detectar síntomas de alarma.
  • La administración se centra en la educación del paciente, las modificaciones en la dieta, la fibra y los antiespasmódicos.
  • Los tratamientos avanzados se dirigen a los síntomas graves a través de neuromoduladores, medicamentos específicos para receptores y terapias psicológicas.

Conclusiones:

  • La gestión eficaz de la EII requiere un enfoque empático, que mejore la calidad de vida y reduzca los costos de atención médica.
  • El eje intestino-cerebro es central para la fisiopatología del SII, con investigaciones en curso que producen nuevos candidatos a fármacos.
  • Se anticipa una creciente cartera de nuevas terapias para el SII basadas en recientes conocimientos fisiopatológicos.
