Connective Tissue Disease Flashcards
Overview- what is Rheumatoid Arthritis (RA)?
Inflammatory arthritis associated with wrist and hands. Inflammation and thickening of the joint capsule. Also may impact bone and cartilage.
Difference between Rheumatoid arthritis and osteoarthritis
Rheumatoid- autoimmune disease where self Ab attacks joints.
Osteo- Due to mechanical wear and tear of joints.
Who is more likely to have RA?
- Women 3x more likely
- Genetic predisposition
Symptoms of RA
pain and swelling in joints. Worsens after rest.
How to diagnose RA
Rheumatoid factor, erythrocyte sedimentation rate (ESR), C-reactive protein, Anti CCP
Ocular implications of RA
-Dry eye is the most common. (Women are 9x more commonly affected)
-Scleritis: Deep intolerable boring pain, redness, photophobia and tenderness
-Episcleritis: Painless red eye, minimal vision impact.
Peripheral ulcerative keratitis- Thinning of cornea that may lead to ulcers and loss of the eye
Treatment of RA
- Steroids to suppress immune system, plaquenil (side effect of building up in cells and causing toxicity to photoreceptor cells)
- Scleral lenses, preservative free artificial tears, restates to help dry eye
Sjogren Syndrome (SS) Overview
Excessive dryness of eyes, mouth, and other mucous membranes. Due to WBC damaging glands such as lacrimal, or salivary.
SS diagnosis
Labs- antinuclear Ab, Sio (blood work), biopsy of salivary glands
Who is most likely to have SS
Middle age women, with lower estrogen levels. Often comes along with other autoimmune diseases.
SS symptoms
Vary greatly as can be associated with RA, SLE, more
ocular implications of SS
Dry eye syndrome is the most common
-SPK (tight junctions in between cells are unstable) or ulceration also possible.
Treatment of SS
-Steroids, artificial tears, restasis, gum to enhance salivary production (no excess water).
SLE (lupus) overview
Problems in joints, nervous system, blood, skin, kidneys,Gi tract, lungs.
Other tissues and organs may be impacted
Diagnosis of SLE
Antinuclear antibody test (ANA) and blood counts. (low RBC, WBC, and platelets.)
There are 17 criteria for classification of the disease. To be diagnosed, patients must have 4 of the 17 classifiers.
