Exam 3 - Rheumatology Flashcards
What is fibromyalgia?
Disorder included with rheumatologic conditions - characterized by symptoms of widespread MS pain, fatigue, nonrestorative sleep, depression, HA, GI complaints (e.g. IBS)
- More than 3 months of MSK pain
Fibromyalgia diagnostic considerations
- Must meet report of pain survey in 19 areas as well as severity of symptoms → replaced tender point examination
- More common in females, ages 40-50 years
American College of Rheumatology criteria for diagnosing fibromyalgia
- WPI >7 and SSS score >5 OR WPI of 4-6 and SSS score >9
- Generalized pain (in at least 4-5 regions)
- Symptoms present for longer than 3 months
Fibromyalgia clinical presentation
- Persistent widespread pain
- Chronic fatigue
- Somatic complaints → non restorative sleep, cognitive difficulties, auditory/vestibular/ocular complaints, chronic rhinitis or “allergies”, migraines, palpitations, IBS, subjective sense of joint swelling, mood disorders
Fibromyalgia physical examination findings
- Normal muscle strength
- No evidence of synovitis or soft tissue inflammation
Are labs indicated for the diagnosis of fibromyalgia?
- CBC, chem profile, TSH, ESR, CRP to exclude other disorders
- ANA, rheumatoid factor, anti-citrullinated protein antibody (ACPA) only in setting of synovitis, lupus, or RA
- Sleep study for OSA
Can fibromyalgia be diagnosed back on history and physical examination alone?
Yes, but want to exclude other causes first
- Patient report of widespread pain present in up to 19 + fatigue + disordered sleep for >3 months
Non pharmacological management of fibromyalgia
- CBT
- Exercise (to combat muscle wasting)
- Acupuncture
- Massage
- Chiropractor
Pharmacological management of fibromyalgia
- TCAs (amitriptyline, cyclobenzaprine)
- SNRIs (duloxetine and milnacipran)
- Gabapentin (Neurontin) and pregabalin (Lyrica) for pain
- Tylenol
- Opioids ONLY after all other meds and therapies failed
What are the four stages of a gout attack?
- Asymptomatic hyperuricemia → elevated serum urate but no acute attacks, crystals may deposit in joints and cause asymptomatic damage
- Acute gout attacks → activation of inflammatory response leading to intense pain, swelling, redness, warmth
- Intercritical gout (intervals between acute attacks)
- Chronic tophaceous gout → due to uncontrolled hyperuricemia
- Firm swelling most commonly found on digits of hands and feet, and olecranon bursa
Risk factors for gout
- Use of diuretics or low dose aspirin use
- Obesity
- CKD
- Metabolic syndrome
- Advanced age
- Local trauma
- Binges of alcohol
- Overeating/fasting
- Newly initiated urate-lowering therapy
How does gout appear in men vs women?
- Recurrent episodes of painful monoarthritis in men
- Oligoarticular arthritis (4 or fewer joints) in postmenopausal women and men with subsequent flares
Acute gout clinical presentation
- Rapid onset (pain peak within 2-4 hours) and increasing pain
- First attack at night and patient wakes up from sleep
- Tenderness, warmth, redness, swelling, decreased ROM in affected joint (usually in first MTP)
- Heberden’s nodes
Gout diagnostic studies
Confirmed with needle aspiration → MSU crystals in synovial fluid or tophi aspiration
What are the goals of gout management?
1) treat acute attacks
2) lowering of total body uric acid pool to prevent tissue deposition of MSU crystals
3) anti-inflammatory prophylaxis to prevent further acute attacks
Non pharmacologic management of gout
- Avoid diuretics
- Control weight
- Limit alcohol consumption
- Consume low fat dairy products, cherry juice concentrate
- DASH diet
- Topical ice
Pharmacologic management of acute gout attacks
- NSAIDs and oral corticosteroids for initial treatment (corticosteroids preferred of CrCl <50, on anticoagulant therapy, or hepatic dysfunction)
- Colchicine should be used within 36 hours of onset of acute attack
- NOT used if GFR is <50
Pharmacologic management of chronic gout attacks
- Urate lowering therapy (ULT) should be started 4-8 weeks after attack is resolved
- Xanthine oxidase inhibitors (allopurinol, febuxostat)
- Uricosuric agents (probenecid, lesinurad)
- Recombinant uricase (pegloticase)
What is considered chronic gout?
Patients who have 2+ gout attacks a year
True/false: There is an increase in acute attacks after ULT therapy initiation for gout
True - due to inflammation caused by changes in the chemical and/or physical state of preexisting MSU crystals
What medication should be prescribed to patients prophylactically for patients starting ULT therapy for gout?
- Give prophylactic low dose anti inflammatory treatment when initiating patient on ULT → e.g. colchicine
- Alternative → NSAIDs
What are the three types of treatment for gout?
- Medications to control attacks of joint pain (NSAIDs, colchicine, corticosteroids)
- Prophylaxis (colchicine, NSAIDs)
- Medications to lower uric acid levels (allopurinol, febuxostat)
OA risk factors
- Female (middle age and older)
- Obesity
- Prior trauma
- Genetics
- Repetitive activities
- Metabolic disorders
- Neurologic disease
- Hematologic conditions
OA vs RA
OA clinical presentation (history)
- Insidious, progressive pain/stiffness of one or more joints
- Symptoms common after waking up (duration <1 hour)
- Pain with weight bearing activities
- Crepitus, swelling, joint deformity, gradual loss of motion
OA physical examination findings
- If cervical or lumbar spine spine is involved, neuropathy and radiculopathy → groin/butt pain causes patient to “favor” the hip → Trendelenburg gait
- Heberden nodes (distal) and Bouchard nodes (proximal)
OA diagnostic studies
X-ray (will see radiographic changes as disease progresses)
Pharmacological management of OA
- Pills
- Acetaminophen → first line
- Tramadol for moderate to severe pain
- NSAIDs (may be given with H2 blockers or PPIs to reduce GI intolerance)
