What are risk factors for acute gouty arthritis?
Obesity
HTN
Kidney disease
DM
Family Hx
Purine rich foods
Alcohol
Medications
2 or more sugar-sweetened soft drinks/day, fruits high in fructose or any fruit juices
What types of foods are rich in purines and not recommended for Gout?
-Seafood (mussels, anchovies, scallops, sardines, shrimp, lobster)
-Organ Meat
-Alcohol (beer more than wine/liquor
-Beans
-Spinach
-Asparagus
-Oatmeal
-Bakers/Brewer’s yeast (supplement use)
What medications are known to precipitated Gouty attacks by causing hyperuricemia?
-Diuretics
-Loop Diuretics (Thiazides Prograf)
-Niacin
-Aspirin
-Cyclosporin
What is Gout?
Inflammatory arthritis that is caused by a decrease in excretion by the kidneys or uric acid. The uric acid accumulates in the joints, bones and subcutaneous tissue.
What are some causes of secondary Gout that produce and increase in renal uric acid clearance?
-Psoriasis
-Myeloproliferative/Lymphoproliferative Dis
-Hemolytic anemia
What are some causes of secondary Gout that produce and decrease in renal uric acid clearance?
-Kidney Disease
-Renal failure
What is Gouty Toe?
-Pain, swelling, erythema of big toe
-Swelling on the medial boarder of the big toe
-100 x more common than monoarticular septic arthritis
What are tophi (Gout)?
-accumulate with frequent flare ups
-nontender firm nodules in soft tissues
-gouty crystals fill the tophi
-precipitates in cooler areas of the body (external ear, nasal cartilage, extensor, surfaces of hand/feet/elbow
What are the diagnostics and labs used for Gout?
-analysis of joint aspirate (urate crystals)
-uric acid serum levels (elevated)
-ESR (elevated)
-CRP (elevated)
What is the treatment of acute Gout?
-Minimize/remove contributing factors
NSAIDs (avoid aspirin it precipitates UR)
-Colchicine
-Oral steroids (prednisone)
-Corticoid steroid local injection
-Pegloticase (IV infusion q 2 wks)
What is the treatment for prevention of Gouty flare ups?
-Allopurinol
-Febuxostat
-Probenecid
Why is colchicine often poorly tolerated?
GI issue (recommend to tape does)
Why is aspirin contraindicated in the treatment of Gout flare ups?
Aspirin is a precipitate for gout
When should you avoid treating Gout flare ups with NSAID for patients?
Patients taking warfarin, renal failure, peptic ulcer disease
What is Pegloticase indication, MOA, and, adverse effects, administration for Gout?
-Use for patients with chronic gout that is refractory to other medications
-contains an enzyme that catalyzes the oxidation of uric acid to allantoin (water soluble metabolite readily eliminated from the body, thus lowering serum UR)
-infusion rxn, and CHF exacerbation
-IV infusion q 2 weeks for at least 6 months
What medication are used to prevent Gout and if they limit the body’s production or improve kidney excretion of uric acid thus affecting serum uric acid levels?
-Allopurinol (limits ur production)
-Febuxostat (limits ur production)
-Probenecid (improves kidneys ability to remove ur from the body)
What is Probenecid MOA, and adverse effects?
-improves kidneys ability to remove ur from the body thus leading to high concentrations of ur in the urine
-greater risk of kidney stones
-rash, abdominal pain
What are common adverse effects of allopurinol?
-rash, low blood counts
-limits amount of ur the body makes
What are common adverse effects of febuxostat?
-limits the amount of ur the body makes
-rash
-nausea
-reduced liver function
What is the purpose of a 24-hour urine collection and when it is indicated when treating/managing a gouty flare up?
-determine if there is overproduction or under secretion of uric acid and will determine which medications are best used for long term management of gout
-overproduction (allopurinol, febuxostat)
-under secretion (probenecid)
What additional medications have been found to work as adjuncts to gout medications and aid in urate excretion?
-fenofibrate
-losartan
What is pseudogout? Where is most commonly seen? What are risk factors? What are the S/S?
What other endocrine conditions is it associate with? How do you diagnosis? What is the treatment?
-presence of (CPPD) calcium pyrophosphates deposition in the joints
-knees, wrists, ankles
-RF: older age, family history, mineral imbalances)
-warm, swollen, painful joints
-Hypothyroidism, hyperparathyroidism
-Dx: presence of CPPD crystals in the affected joint
-Treatment: NSAIDs, colchicine, oral corticosteroids (pain relief and improve joint function)
What are some causes of secondary gout?
-psoriasis
-hemolytic anemia
-renal failure
What is seen in the clinical presentation of a gouty toe?
-swelling on the medial aspect of the join
-pain, swelling of joint
