20
Q

Vit B12 deficiency in celiac?

Study These Flashcards
A

Peripheral neuropathy

21
Q

Celiac disease may coincide w what?

Study These Flashcards
A

Lactose intolerance

22
Q

Physical exam is usually normal for celiac unless there is a finding related to what ?

Study These Flashcards
A

Nutrient deficiency

23
Q

What is dermatitis herpetiformis?

Study These Flashcards
A

Cutaneous variant of celiac disease: pruritic raised papulovesicles over extensors of extremities, trunk, scalp, neck (very itchy!!) w little to no GI symptoms

24
Q

Small intestine biopsy will show what with dermatitis herpetiformis?

Study These Flashcards
A

Histology correlated w celiac

25
How many patients w celiac have DH?
Few
26
Treatment of HD?
Dapsone- anti inflammatory, also alleviate itching to avoid infection
27
Will DH lesions respond to a GF diet?
Yes but response is slow, attempt to start GF diet and dapsone simultaneously and wean off dapsone to hopefully control w only diet once responding
28
Ddx for celiac disease?
IBS, eosinophilic gastroenteritis, bacterial overgrowth (surg complication, slower gut transit,obstruction), lactose intolerance, IBD
29
Gold standard for evaluation of celiac disease?
Small intestinal biopsy: taken from proximal & distal duodenum
30
Histopathology of SI biopsy shows what for celiac?
Partial to complete villous atrophy and intraepithelial lymphocytes
31
What does celiac serology check for?
Antibodies IgA endomysial and IgA tissue transglutaminase 
32
What is the sensitivity and specificity of celiac serology?
Both blood tests have a greater than 90% sensitivity and greater than 95% specificity
33
What should you consider about serology testing for somebody following a gluten-free diet?
If someone is gluten-free on their own, already at can skew the results
34
Which serology test is usually the initial test and which test is used to confirm results?
TTG usually initial test and endomysial to confirm
35
Lab test for celiac disease may have abnormal value is related to what?
Specific nutrient deficiency such as anemias, low vitamin levels, and low calcium
36
What is the treatment for celiac disease?
Lifelong strict, elimination of gluten from diet, correct, nutritional deficiencies, support groups
37
When will symptom improvement be evident after switching to a gluten-free diet?
Within a few weeks
38
When will antibody levels become undetectable and somebody with celiac disease?
Undetectable after 3 to 12 months on gluten free diet
39
What kind of referral should you give somebody with celiac disease?
Dietitian
40
What’s important to remind patients about food, especially processed food when on a gluten-free diet?
Food may be cross contaminated 
41
Which grains are safe for someone with celiac disease?
Rice, corn, potatoes, buckwheat, soybean, tapioca flours safe Caution w oats
42
Why are support groups beneficial for those with celiac disease?
There is usually an increase in anxiety and depression in a newly diagnosed patient
43
What are associations and complications of celiac disease?
Increased incidence of G.I. and non-G.I. cancer and intestinal lymphoma, development of intestinal ulceration, association with type one diabetes, down syndrome, turner syndrome, other autoimmune diseases
44
What is the prognosis for celiac disease?
Excellent with proper diagnosis, treatment, strict diet, adherence
45
What is a non-celiac gluten sensitivity?
A symptomatic response to gluten ingestion with no serologic or histologic changes
46
What kind of symptoms does non-celiac gluten sensitivity have?
Similar symptoms to celiac disease: abdominal pain, bloating, change in bowel patterns
47
How fast are the onset of symptoms for non-celiac gluten sensitivity?
Hours to days after ingestion
