connective tissue diseases Flashcards
what are the 2 categories of connective tissue diseases
autoimmune and vasculitic
describe autoimmune connective tissue diseases
tissues themselves which are affected
examples include systemic lupus erythematosis , sjogrens and systemic sclerosis
Have associated blood antibodies - these are not a cause of disease but some patterns can indicate what disease may be a problem
describe vasculitic connective tissue diseases
blood vessels affected - inflammation causing thickened walls therefore narrowed lumen and decreased blood flow. leads to infarction of tissues
named according to size of blood vessel affected e.g large vessel, medium vessel and small vessel
connective tissue disease treatments
no cure for any as the cause is still unclear
- analgesic NSAIDs for pain
- immune modulators - methotrexate , hydroxychloroquine
- systemic steroids - prednisolone
name 3 common autoantibodies assosciated with connective tissue diseases
anti- nuclear, anti -ro and anti - la
systemic lupus erythematosis
multi system autoimmune disease causing joint pain, skin rashes, cns issues, cv issues and more
systemic changes and autoantibodies present
genetic and environmental causes
external symptom of systemic lupus erythmatosis
butterfly rash on face due to photosensitivity (sunlight)
dental effects of systemic lupus erythmatosis
chronic anaemia - ulceration risk
bleeding tendency - thrombocytopenia
renal disease - impaired drug metabolism / excretion
lichenoid oral reactions
some drugs can increase photosensitivity
sjogrens syndrome
inflammatory disease affecting fluid producing tissues e.g saliva and lacrimal glands
associated with circulating antibodies - anti nuclear, anti ro and anti la
main symptoms = dry eyes and mouth
sjogrens - sicca syndrome
only dry eyes OR dry mouth
primary sjogrens syndrome
dry eyes AND dry mouth
no other connective tissue disease
secondary sjogrens syndrome
dry mouth AND dry eyes alongside another connective tissue disease e.g rheumatoid arthritis, systemic lupus eythematosis
dental impacts of sjogrens
decreased saliva = increased caries and infection risk
decreased denture retention
functional loss
increased risk of sialosis - swelling of salivary glands
systemic sclerosis (slerodema)
disease where elastic tissue is replaced by fibrous connective tissue resulting in hard, thickened areas of skin
Inability of organs e.g skin to stretch around joints, oesophagus cant stretch around food bolus etc
dental impacts of systemic sclerosis (sclerodema)
poor mouth opening (no elasticity)
poor oral access and therefore often poor OHI
may be compouded with sjogrens
reflux and dysphagia - erosion
