Coeliac disease Flashcards
When does coeliac disease usually present in kids
may occur at any age
-usually noticed at 6-9 months when child is weaning (introduction of gluten)
presenatino of coeliac disease in children 7
- stools- normal to pale and bulky
- abdo distened
- buttocks wasted
- failure to thrive
- mouth ulcers
- anaemia seocndary to iron, B12 or folate deifcicey
- dermatitis herptiformis -ithcy blisteing skin rah typically on abdomen
*-rarely- neurosyx
-peripehral neuropathy
cerebellar ataxia
epilepsy
what shoudl always be tested in conjuction with coeliac disease
if a patient presents with new type 1 diabetes
-test for coeliac disease
-conditions are often linked
autoantibodies found in coeliac disease 2
- anti-TTG
- anti-EMA
where in the bowel does coeliac disease typically afect 1
-what does it cause 1
jejunum
-atrophy of intestinal villi
genetic associations to coeliac disease 2
HLA-DQ2
HLA-DQ8
what type of Ig are anti-ttg and anti-ema
-why is this imporatnt to remeber during testing
IgA
-important to test for total Immunoglobulin A levels because if total IgA is low the coeliac test will be negative even when they have the condition. In this circumstance you can test for the IgG version of the anti-TTG or anti-EMA antibodies or do an endoscopy with biopsies.
important point about carrying out investiagtions in patients with coeliac disease
must remain on diet containing gluten otherwise may not be possible to detec antiboides or inflam in the bowel
what must be checked before testing specific autoantiboides in coeliac disease
total immunoglobulin A levels to exclude IgA deficiency
what will endoscopy and intestinal biopsy in coeliac disease show 4
villous atrophy
crypt hyperplasia
increase in intraepithelial lymphocytes
lamina propria infiltration with lymphocytes
investigations for coeliac disease
TTG-IgA- highly sensitive and speicic
-if >10n TTG diagnoiss can be made with repated bloods and a trained dietician
moderaltely elevated TTG- duodenal mucosal biospy is necessary
what histological changes are seen on duodenal mucosal biopsy in coeliac disease3
- villous atrophy
- crypt hyperplasia
inreased intraepithelial lymphocytosis
What conditions are coeliac disease associated with 6
- Type 1 diabetes
- Thyroid disease
- Autoimmune hepatitis
- Primary biliary cirrhosis
- Primary sclerosing cholangitis
- Down’s syndrome
complications of untreated coeliac disease 7
- Vitamin deficiency
- Anaemia
- Osteoporosis
- Ulcerative jejunitis
- Enteropathy-associated T-cell lymphoma (EATL) of the intestine
- non-Hodgkin lymphoma (NHL)
- Small bowel adenocarcinoma (rare)
coeliac disease management 1
life long gluten free diet
