Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy01:30

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

315
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

5.0K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Inflammatory Bowel Disease I: Ulcerative Colitis

135
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

386
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...

Inflammatory Bowel Disease II: Crohn's Disease

183
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Autoimmune Disorders01:29

Autoimmune Disorders

385
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
Concept and Mechanism of Autoimmune Diseases
The immune...

Summary

Infants with allergic proctocolitis (AP) have lower vitamin D (vit D) levels. Low vit D is linked to a higher risk of developing AP, suggesting a potential association and the need for assessment.

Area of Science:

  • Pediatric Allergy and Immunology
  • Nutritional Science
  • Gastroenterology

Background:

  • Rising global prevalence of allergic diseases, including allergic proctocolitis (AP), in infants.
  • Increased awareness of vitamin D (vit D) deficiency and its potential role in immune-mediated conditions.

Purpose of the Study:

  • To evaluate vitamin D (vit D) levels in infants diagnosed with allergic proctocolitis (AP).
  • To explore a potential relationship between vitamin D status and the development of AP in infants.

Main Methods:

  • Prospective, observational, case-control study design.
  • Inclusion of infants aged 6 months and younger: 72 with AP and 44 healthy controls.
  • Comparison of serum vitamin D levels at diagnosis between AP patients and controls.

Main Results:

  • Significantly lower vitamin D levels observed in infants with AP compared to healthy controls.
  • Vitamin D deficiency or insufficiency noted in 34.7% of infants with AP.
  • Infants with vitamin D levels below 40.75 mcg/L had a 3.5 times higher risk of developing AP.

Conclusions:

  • Lower vitamin D levels in infants with AP support an association between vitamin D deficiency and the condition.
  • Findings may offer insights into environmental factors contributing to the increasing prevalence of AP.
  • Recommendation for routine assessment of vitamin D levels in infants diagnosed with AP.
