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

291
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...

Dipeptidyl Peptidase 4 Inhibitors

155
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Area of Science:

  • Periodontology
  • Metabolic Health
  • Nutritional Science

Background:

  • Experimental gingivitis is a common oral health concern.
  • Fasting protocols, such as Bahá'í dry fasting (BF) and 16:8 time-restricted eating (TRE), are increasingly studied for their health impacts.
  • Understanding the interplay between diet, fasting, and oral health is crucial.

Purpose of the Study:

  • To compare the effects of BF and TRE against a control group (CG) on periodontal health during experimentally induced gingivitis.
  • To assess the impact of these dietary interventions on key metabolic and inflammatory markers.

Main Methods:

  • Sixty-six healthy participants were recruited for this study.
  • Participants underwent a 9-day period of no oral hygiene to induce gingivitis, followed by a 19-day observation period with resumed hygiene and assigned dietary protocols (BF, TRE, or CG).
  • Periodontal parameters (bleeding on probing, plaque index, gingival crevicular fluid) and metabolic markers (blood pressure, body weight, HbA1c, C-reactive protein) were measured.

Main Results:

  • Bahá'í dry fasting (BF) showed a significantly reduced increase in bleeding on probing (BOP_s) compared to both the control group (CG) and time-restricted eating (TRE).
  • Gingival crevicular fluid (GCF) levels increased in the CG but not in the BF or TRE groups.
  • Significant differences in the changes of BOP_s and GCF were observed between the fasting groups (BF, TRE) and the CG.

Conclusions:

  • Both Bahá'í dry fasting (BF) and 16:8 time-restricted eating (TRE) demonstrate beneficial effects on experimental gingivitis and associated metabolic parameters.
  • Fasting interventions may offer a protective effect against gingivitis development.
  • Limitations include randomization issues and potential bias in the BF group, warranting further investigation.
