Assessment of the Gastrointestinal System I: Subjective Data

866
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Summary
This summary is machine-generated.

Noncoeliac gluten sensitivity (NCGS) prevalence varies widely, with some patients potentially having mild celiac disease. A gluten-free diet (GFD) shows controversial benefits for NCGS but may help specific irritable bowel syndrome (IBS) patients.

Area of Science:

  • Gastroenterology
  • Immunology
  • Dietary Science

Background:

  • Noncoeliac gluten sensitivity (NCGS) is an emerging disorder characterized by gluten intolerance symptoms.
  • NCGS diagnosis relies on excluding celiac disease due to a lack of specific biomarkers.

Purpose of the Study:

  • To determine the prevalence of NCGS.
  • To evaluate the diagnostic exclusion of celiac disease in NCGS patients.
  • To assess the efficacy of a gluten-free diet (GFD) for NCGS patients.

Main Methods:

  • A comprehensive PubMed search was conducted up to December 2014.
  • NCGS was defined using consensus criteria: self-reported gluten intolerance, negative celiac serology, and absence of villous atrophy.
  • Included studies evaluated GFD impact on NCGS and irritable bowel syndrome (IBS) patients.

Main Results:

  • NCGS prevalence ranged from 0.5% to 13%, with significant variability.
  • A subset of NCGS patients (20%) were reclassified as celiac disease after advanced diagnostics (lymphocytic enteritis and HLA-DQ2/DQ8 haplotypes).
  • A GFD showed variable results for NCGS but significantly improved stool frequency in HLA-DQ2 positive, diarrhea-predominant IBS patients.

Conclusions:

  • NCGS prevalence is highly variable, and some cases may represent a milder form of celiac disease.
  • The therapeutic benefit of a GFD for NCGS patients remains controversial.
  • GFD may offer symptomatic improvement for specific IBS patient subgroups (HLA-DQ2 positive, diarrhea-predominant).
