UNIT 3- RHEUMATOID ARTHRITIS Flashcards
OA vs. RA what are the ages of onset?
OA: usually begins after age 40
RA: May begin at any age usually before age 50
OA vs. RA Where is the joint pain located?
OA: Usually effects eight-bearing joints, such as the knees and hips, but also effects the ginger joints, pain is often on 1 side of the body only
RA: Usually effects small joins, such as the hand, foot, wrist, elbow, shoulders or ankle usually on both sides of the body
OA vs. RA What is the appearance of the joints?
OA: Usually cool, not red or swollen
RA: Inflammatory causes joints to be warm, red, swollen.
OA vs RA: Length of morning joint stiffness?
OA: Lasts only a few mins
RA: Lasts for at least 60 mins and can persist for hours
OA vs. RA: What are the symptoms besides joint pain stiffness?
OA: Usually does not affect overall health
RA: May be accompanied by fatigue, weight loss and fever.
OA vs. RA: What is the disease progression like?
OA: Symptoms gradually worsen over periods of year
RA: Symptoms worsen over a period of weeks to months
OA vs. RA: What eases pain or stiffness?
OA: Pain subsides with rest and worsens w/activity
RA: Stiffness decreases w/activity
What is rheumatoid arthritis?
Chronic, systemic autoimmune disease that causes inflammation of connective tissue in joints.
Usually exhibits extraarticular manifestations (outside of the joints)
There are periods of remission and exacerbation
True or False: There is a genetic link with RA?
True
What is the etiology of RA?
Autoimmune- combination of genetics and environmental triggers
- Antigen triggers formation of abnormal immunoglobulin (IgG)
- Autoantibodies develop against the abnormal IgG
-RF factor
What are the 5 stages of RA?
1.Healthy joints
2. Synovitis
3. Pannus
4. Fibrous ankylosis
5. Bony Ankylosis
What should we know about stage 2 of RA- Synovitis?
- Synovial membrane inflamed and thickened
- Bones and cartilage gradually erode
What should we know about stage 3 of RA- Pannus?
- Excessive cartilage loss; exposed and pitted bones
What should we know about stage 4 Fibrous ankylosis of RA?
- Joint invaded by fibrous connective tissue
What should we know about stage 5 RA bony ankylosis?
- Bones fused
What is the onset of RA?
Typically insidious- slow and sneaky
What are some clinical manifestations of RA?
- Fatigue
- Anorexia
- Weight loss,
- generalized stiffness
True or False: some patients may report a history of precepting event that triggers there RA?
True- Some examples are infections, stress, exertion, childbirth, surgery, emotional upset
Symptoms of RA typically occur asymmetric or symmetric?
Symmetrical
How long can morning RA stiffness last
60mins.
How will the joints present in RA?
Tender, painful and warm to touch
True or false: Skin might get tight around a joint with RA?
True
What is Tenosynovitis?
Inflammation of the tendon sheath where muscle connects to bone
True or false: Deformity and disability are not common in RA?
False
What are the typical deformitites of RA?
- Ulnar deviation
- Boutonniere
- Bunions
- Swan neck
What is ulnar deviation?
Also known as ulnar drift. This hand condition occurs when your knuckle bones or metacarpophalangeal (MCP) joints, become swollen and cause your fingers to bend abnormally toward your little finger.
What is Boutonniere?
Flexion of the proximal interphalangeal and the distal interphalangeal joint
What is swan neck deformity?
Characterized by proximal interphalangeal (PIP) joint hyperextension and flexion of the distal interphalangeal (DIP) joint
What are the extraarticular manifestations of RA?
- Rheumatoid nodule
- Sjogren’s syndrome
- Felty syndrome
- Flexion contractures
- Depression
What are we concerned about when a person with RA presents with Rheumatoid nodules?
Our concern is skin breakdown. These nodules are not usually painful– as they are just inflamed tissue that hardens over time. But overall this increases the risk of skin breakdown.
What is important to know about Sjogren’s syndrome?
- Can happen on its own or as a part of RA
What does Sjogren’s syndrome effect?
- Targets salivary and tear glands which leads to dry mouth and eyes.
- Patients may have difficulty swallowing and may be more prone to injections due to dry eyes and dental carriers.
Review: These are the systems in the body that RA effects.
- Pleura: Effusions
- Lymph nodes: Reactive lymphadenopathies
- Kidney: amyloidosis
- Gut: Amyloidosis
- Bone marrow: anemia, thrombocytopenia
- Nervous system: peripheral neuropathy (mononeuritis multiplex)
- Eye: scleritis keratoconjunctivitis
- Pericardium: Effusions
- Lung: Fibrosis nodules effusion (these pts can be diff. to get off vents) TCDB important because lungs harden
- Spleen: Splenomegaly
- Muscle: wasting
- Skin: Thinning–> ulceration
True or false: RA can effect any body system… usually the higher the inflammation in the body the more likely you are to have a systemic impact?
True
