Study Notes
Irritable Bowel Syndrome (IBS)
- Chronic disorder affecting gut-brain interaction, often debilitating and prevalent.
- Characterized by recurrent abdominal pain and disordered defecation.
- Rome IV diagnostic criteria help to categorize IBS.
- Primary symptom is recurrent abdominal pain.
Celiac Disease
- Immune-mediated disorder caused by gluten in genetically predisposed individuals leading to enteropathy.
Diagnostic Markers for IBS
- Routine check for fecal calprotectin, fecal lactoferrin, and C-reactive protein in suspected IBS-D patients without alarm features.
- Calprotectin is preferred with moderate-quality evidence for IBS diagnostics.
Excluding Inflammatory Bowel Disease (IBD)
- Common serologic tests include Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) to rule out IBD in IBS-D patients.
- CRP is particularly useful for distinguishing IBD from IBS.
Testing Recommendations
- Routine stool testing for enteric pathogens not recommended for all IBS patients.
- Routine colonoscopy not advised for patients under 45 without warning signs.
- No routine testing for food allergies or sensitivities in IBS patients.
- Anorectal physiology testing recommended for those with pelvic floor disorder symptoms.
Dietary Recommendations for IBS
- A low FODMAP diet is suggested to alleviate global symptoms.
- FODMAPs: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols can trigger symptoms due to increased GI secretion and fermentation.
- Soluble fiber (e.g., psyllium, oat bran, barley, beans) is recommended, while insoluble fiber (e.g., wheat bran, whole grains) can aggravate symptoms.
- Antispasmodics are not recommended, but peppermint may provide relief.
Probiotics and Pharmacological Treatments
- Probiotics suggested for IBS treatment.
- Polyethylene glycol (PEG) products not recommended.
- Chloride channel activators and guanylate cyclase activators are recommended for IBS-C symptoms, including Lubiprostone, Linaclotide, and Plecanatide.
- Tegaserod recommended for IBS-C in women under 65 years with few cardiovascular risk factors.
- Rifaximin, an FDA-approved nonabsorbed antibiotic, is recommended for IBS-D.
- Alosetron recommended for women with severe IBS-D symptoms unresponsive to conventional therapy.
- Mixed opioid agonists and antagonists like Eluxadoline are accepted for global IBS-D treatment.
- Tricyclic antidepressants (e.g., amitriptyline, nortriptyline) are recommended for treating IBS symptoms.
Fecal Microbiota Transplant
- Not recommended for IBS; primarily used for C. difficile colitis.
Overall IBS Characteristics
- IBS involves abdominal pain associated with abnormal bowel habits, which may include constipation, diarrhea, or both.
- Neuromodulators (e.g., TCAs) have mechanisms targeting pain through norepinephrine and dopamine, aiding in symptom relief.
