Insights
Celiac disease, an immune response to gluten damaging the small intestine, affects 1 in 100 children. Early diagnosis and a lifelong gluten-free diet are crucial for managing this condition.
Area of Science:
- Pediatric Gastroenterology
- Immunology
- Nutrition Science
Background:
- Celiac disease is an autoimmune disorder triggered by gluten ingestion.
- It leads to villous atrophy and malabsorption in the small intestine.
- The condition is more common and presents more subtly than previously thought, affecting approximately 1 in 100 children in the U.S.
Purpose of the Study:
- To highlight the prevalence and varied presentations of celiac disease in children.
- To outline diagnostic pathways for suspected cases.
- To emphasize the importance of dietary management and support systems.
Main Methods:
- Review of celiac disease presentation and diagnosis in pediatric populations.
- Discussion of serologic testing and endoscopic biopsy procedures.
- Emphasis on lifelong gluten-free diet adherence and multidisciplinary support.
Main Results:
- Celiac disease prevalence in U.S. children is estimated at 1 in 100.
- Children may present with overt symptoms (failure to thrive, diarrhea) or subtle signs like constipation.
- Asymptomatic cases also occur, necessitating screening in high-risk individuals.
Conclusions:
- Early diagnosis through serologic testing and biopsy is vital.
- Lifelong gluten-free diet is the primary treatment.
- Comprehensive family education, including dietician consultation and support groups, is essential for successful management.
Abstract:
Celiac disease is a disease of the small intestine caused by an immune response to ingested gluten. This response results in characteristic damage to the villi, resulting in malabsorption. It is far more prevalent and its presentation can be far more subtle than once recognized. The prevalence of celiac disease in children in the general U.S. population is estimated to be 1 in 100. Toddlers and young children classically present with failure to thrive, diarrhea, and abdominal distension sometime after the introduction of gluten in the diet, but more often they present with subtle gastrointestinal symptoms such as constipation. Some children may be asymptomatic. Symptomatic patients and high-risk individuals should have serologic testing and testing of their total immunoglobulin A. Seropositive patients should undergo upper endoscopy and small-bowel biopsy of the distal duodenum. Treatment is lifelong adherence to a gluten-free diet. Families must meet with a dietician and should be strongly encouraged to participate in celiac support groups. The gastroenterology nurse is in an unparalleled position to assist parents of children newly diagnosed with celiac disease to identify the necessary lifestyle changes to make their child's life gluten free.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
