Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

428
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Irritable Bowel Syndrome I: Introduction

395
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...

Drugs for Treatment of Diarrhea-Predominant IBS

308
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...

Drugs for Treatment of Constipation-Predominant IBS

350
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Inflammatory Bowel Disease IV: Pharmacological Management

200
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
Pharmacologic...

Area of Science:

  • Microbiology
  • Neuroscience
  • Gastroenterology

Background:

  • Fibromyalgia is a chronic condition characterized by widespread pain and mood disturbances.
  • The gut microbiome's role in neurological and psychological conditions is an emerging area of research.

Purpose of the Study:

  • To investigate the causal link between gut microbiota composition and fibromyalgia symptoms.
  • To explore the therapeutic potential of fecal microbiota transplantation (FMT) in fibromyalgia.

Main Methods:

  • Fecal microbiota transplantation from fibromyalgia patients to germ-free mice.
  • Assessment of pain hypersensitivity and depression-like behaviors in recipient mice.
  • Fecal microbiota transplantation from healthy donors to mice exhibiting fibromyalgia-like symptoms.

Main Results:

  • Mice receiving microbiota from fibromyalgia patients developed pain hypersensitivity and depression-like behaviors.
  • These symptoms were reversed following FMT from healthy donors.
  • Fibromyalgia patients undergoing FMT reported significant symptom relief.

Conclusions:

  • Gut microbiota composition plays a critical role in the pathophysiology of fibromyalgia.
  • Fecal microbiota transplantation is a promising therapeutic strategy for managing fibromyalgia symptoms.
