Coeliac disease Flashcards
Define coeliac disease
Systemic autoimmune disease against dietary gluten-> attacks the small intestine
Aetiology and risk factors of Coeliac disease
Gluten-> gliadin which resist degradation, Excess transferrin receptors allows gliadin to enter the cell wall-> taken up by macrophage and presented -> anti TTG Ab, Anti-gliadin, anti-endomycial
(these TTG are also found in muscle-but unclear why don’t really get muscle Sx
Leads to breakdown of microvilli (flattened villi), longer crypts (crypt hypertrophy), lymphocyte infiltration-malabsorption
Risk factors HLA-DR, DQ Women>men Fix of coeliac T1DM
Epidiemology of Coeliac
1/100-quite common in UK/US
Signs and Symptoms of Coeliac
Dermitis Herpetoformis-large red rash on top of belly (nothing to do with herpes)
Children present-abdominal distention, FAILURE to thrive, Diarrhae
Adults-Chronic diarrhoea, bloating, OTHER VARIED SX
abdo pain
Aneamia-tired
Investigation of Coeliac
Initial signs tend to be anaemia
Anti-TTG, anti Gliadin and Anti-endomycial
if thats not enough-> biopsy
Management of coeliac
Avoid Gluten
+ vitamin supplements (Vit D and Calcium, possibly iron, B12 and folate
if coeliac crisis-rehydrate and resolve electrolyte imbalance
Complications of Coeliac
Commonly-osteoporosis/penia
Dermatitis herpetiformis
IBS, lactose intolerance
increased chance of malignancy in long run
And pancreatitis
Prognosis of Coeliac
over 90% won’t have any Sx after removing gluten
10% Sx are mainly with IBS, lactose intolerance or still eat gluten
1% get refractory Coeliac
