Chapter 24: Celiac Disease (Children) Flashcards
Celiac Disease
also known as “celiac sprue”, “gluten-induced enteropathy”, and “gluten-sensitive enteropathy”
- disorder in which the proximal small bowel mucosa is damaged as a result of dietary exposure to gluten
- permanent intolerance to gluten
How do you get the disease?
does not present until gluten products have been introduced into the diet
-usually between 6 months and 2 years of age as table foods are introduced into the diet
What is gluten found in?
-wheat
-rye
-barely
-related grains
(rice does not contain toxic gluten and can be eaten freely, as can a special preparation of oats)
The pathology shown for Celiac Disease
reveals a diffuse lesion of the upper small intestine mucosa
-short, flat villi, deepened crypts, and irregular vacuolated surface epithelial layer and crypt hyperplasia are seen via light microscopy
>as the villi flatten out and atrophy (partial or complete wasting away), there is a decrease in the absorptive surface of the intestine
-malabsorption with a decreased fat absorption eventually impacts the absorption of proteins, carbohydrates, and fat-soluble vitamins A, D, E, and K
Signs and Symptoms
> early manifestations: are nonspecific
- anorexia
- irritability
- weight loss
- listlessness
> Classic Presentation: begins around age 6 months to 2 years and is characterized as gluten products are introduced into the diet
- diarrhea
- abdominal distention and bloating
- steatorrhea (bulky, greasy, foul-smelling, and putty-colored stool b/c of large amount of undigested fat content)
- constipation
- vomiting
- abdominal pain
- anorexia
> Atypical Symptoms:
- protuberant abdomen, loss of subcutaneous fat, hypotonia, anorexia, lethargy, and muscle wasting b/c of protein losses
- anemia and bruising b/c of inadequate vitamin k absorption
- growth retardation
- osteoporosis
- delayed puberty development
- iron deficiency anemia
- failure to thrive
- abnormal liver function
- dental enamel defects
- an atypical presentation of celiac disease may delay diagnosis until adult years b/c the extraintestinal manifestations overshadow the GI symptoms, which may be mild or entirely absent
Diagnosis
-clinical symptoms and serological markers
-small bowel biopsy essential to confirm before gluten is eliminated from diet
>positive biopsy reveals atrophy of villi and deep crypts on the intestinal mucosa (definitive test)
-laboratory studies detect antigliadin and antiendomysial antibodies in addition to malabsorption and nutritional deficiencies
Prevention
- cannot be prevented
- symptoms may be reduced through careful dietary education and management
- reading labels
- gluten-free food
Nursing Care
directed at diagnosis, support, and education
Treatment
Gluten-free diet
-eliminate wheat, rye, and to an extent barely and oat products
>corn, rice, and millet are acceptable
Education/ Discharge
- gluten-free diet can heal the damage to the intestine and prevents further damage
- instructed on hidden sources of gluten, which may be found in processed foods such as thickening agents, soups, and luncheon meats; gluten is added to many foods as hydrolyzed vegetable protein
- supplemental calories, vitamins, and minerals are recommended during the acute phase
- normal amounts of fat are suggested
- periodic measurement of transglutaminase is recommended to determine dietary compliance or to reevaluate persistent symptoms after the initiation of a gluten-free diet (GFD)
Optimizing Outcomes for Celiac Disease
- requires a lifelong commitment to diet control
- involves dietary guidance
- carefully read labels for hidden sources of gluten-based products; can be found in ice cream, hot dogs, luncheon meats, soups, and cookies
Children with more severe mucosal damage
-have impaired digestion of disaccharides, especially in relation to lactose; may necessitate need for lactose restriction in diet
-dietary needs: high calories and proteins with simple carbohydrates such as fruits and vegetables
>avoid high-fiber foods such as raw vegetables and fruits with skin, nuts, and raisins until bowel inflammation has been reduced
