Connective Tissue Disease Flashcards
What is inflammatory arthritis?
Autoimmune disease in which the body views its own tissue as foreign
What is seropositive arthritis?
Your blood has antibodies that can attack your body and inflame your joints
An example is rheumatoid arthritis
What is seronegative arthritis?
Your body doesn’t have the antibodies typically made when you have the condition
An example is psoriatic arthritis and ankylosing spondylitis
What is rheumatoid arthritis?
Chronic inflammatory condition that typically affects small and medium sized joints in a symmetric fashion
What is the pathogenesis of rheumatoid arthritis?
The primary lesion is synovitis whereby immune cells invade the normally relatively acellular synovium, leading to the formation of inflammatory ‘pannus’
What tests are done to diagnose someone with rheumatoid arthritis?
Antibody test
- sensitivity measures the proportion of actual positives which are correctly identified as such
- specificity measures the proportion of negative which are correctly identified
What does the rheumatoid factor do?
Autoantibodies which target the Fc-part of the human IgG- activates the complement in the joint, which leads to increased vascular permeability and the release of chemotactic factors recruiting immune-competent effect cells in the joint
What is the treatment for RA?
Anti-cyclic citrullinated peptide autoantibody
Citrullinated peptide
Methotrexate
What is Sjögren’s syndrome?
A condition that affects parts of the body that produce fluid- tears and spit
What are the symptoms of Sjögren’s syndrome?
Xerophthalmia
Xerostomia
How is Sjögren’s syndrome diagnosed?
Schirmer test is performed by placing a test strip in each eye between the medial and lateral parts of the lower eyelid
What are some problems associated with Sjögren’s syndrome?
Tongue sticking to the roof of the mouth Frequent caries Higher risk of periodontal disease Loss of tongue papilla Altered sense of asteroid Inability to eat dry foods Difficulty wearing dentures Development of oral candidiasis Angular cheilitis Parotitis Petechial lesions Erythema
What are some complications of Sjögren’s syndrome?
Emergence of other disorders associated with Sjögren’s syndrome e.g. RA or SLE
Infection of the parotid gland
Tumours of the parotid gland
What is the treatment of Sjögren’s syndrome?
Hydroxychloroquine
What is systemic lupus erythematosis?
An autoimmune disorder characterised by multi system microvascular inflammation with the generation of autoantibodies
