Auto immune disease Flashcards
What are the syptoms of SLE?
Photosensitve malar rash
Multiple mouth ulcers
Athralgia (pain in joints)
Alopecia
Pathology of SLE?
- immune system forms antibodies against proteins/DNA in the nuclei of cells
- anti-nuclear antibodies bind to skin damaged by UV light
- anti-nuclear antibodies plus antigens = immune complex
- these immune complexes can cause inflammation in ANY tissue
Test for Lupis?
Test for anti nuclear antibodies (ANAs)
What is ANCA vasculitis?
Inflammation of vessels caused by ANCA (anti neutrophil cytoplasmic antibodies).
All have polyangitis
Some have granulomata also
Most imortant type of ANCA vasculitis?
Wegener’s granulomatosis (WG), is a systemic disorder that involves both granulomatosis and polyangiitis.
What is the test for ANCA vasculitis?
Test for ANCA
Treatment for ANCA vasculitis?
Immune surpression
What is the pathology of Pernicious anaemia?
AI blocks intrinsic factor
Parietal cells cant absorb B12 anymore
What kind of anaemia does pernicious aneamia cause/is?
Macrocytic anaemia
What is the pathology of Myasthenia gravis?
Auto antibodies block ACH receptor
What is often swollen in MG?
Thymus gland - if remove it can be cured (apparently although i doubt this)
What are the two types of Raynauds?
Primary and secondary
Tell me about primary Reynauds
Harmless
Young women
ANA negative
Tell me about secondary Raynauds?
ANA positive
Can be ascosiated with scleredoma
What does Graves disease cause?
Hyperthyroidism
What does Hashmitos cause?
HYpothyroidism
How does Graves works?
Anti TSH antibody
get low TSH high t3 t4
What can make proteins more immunogenic?
Citrullination
What is coeliac disease?
Anti-transglutaminase antibodies to the enzyme tissue transglutaminase (tTG) are found in the blood of the majority of people with classic symptoms
What is the difference between autoinflammation and auto immunity?
AI
- b cells and t cells
- autoantibodies present
- continuous progression
- therapy = anti b/t cell
Auto inflam
- neutrophils and macrophages
- thereapy = anti cytokine
- no auto antibodies
