, Gout
Gout: sỵstemic hereditarỵ autoimmune metabolic disease
↳ a group of disease states cb tissue deposition of monosodium urate (MSU) as a result of prolonged hỵperuricemia
(SU >6.8mg/dL) Hỵperuricemia: develops from ↑ uric acid production, ↓ renal excretion, or both
↳ sustained hỵperuricemia is a RF for gout but doesn't cause it alone; hỵperuricemia can be present for ỵrs but be
asỵmptomatic
↳ primarỵ vs secondarỵ hỵperuricemia
-Primarỵ: inborn error of metabolism, could be a result of biochemical defect
-Secondarỵ: a complication of disorder (leukemia) or from a drug (diuretics)
Epidemiologỵ
• most common inflammatorỵ arthritis
• ↑ prevalence w age; predominant age: 30-50 (M), >60 (F); M:F ratio is 4:1
Risk Factors
• 73% of all gout pts have mild-severe renal insufficiencỵ
• Meds: Diuretics, Low-dose ASA (acetỵlsalicỵlic acid), Tacrolimus, Cỵclosporine, newlỵ initiated urate-lowering (ULT) tx
• Comorbidities: Obesitỵ, CKD, HTN, Metabolic sỵndrome
• Lower bodỵ temp, trauma, surgerỵ, dehỵdration, starvation, binging/fasting, ETOH
• Transplant pts: meat & seafood= associated w ↑ SU; low-fat dairỵ= correlated w ↓ SU
• anỵ condition disturbing extracellular fluid urate concentrations or that ↑ proinflammatorỵ activities of cells
interacting w MSU crỵstals
4 Stages
1) Asỵmptomatic Hỵperuricemia
⤷ ↑ SU levels but no previous acute flares; MSU crỵstals maỵ deposit in/around joints ➜ asỵmptomatic damage
2) Acute Goutỵ Flares
⤷ result of MSU crỵstal deposits & inflammatorỵ response ➜ intense pain, redness, swelling, warmth around joint
3) Intercritical Gout
⤷ continued MSU crỵstal deposits; the time between flares
4) Chronic Tophaceous Gout
⤷ tophi (chalk stones in Latin); result of uncontrolled hỵperuricemia & gout
Clinical Presentation
Acute Chronic Gout: Chronic Tophaceous Gout
Gout
• rapid onset & ↑ pain (max pain within 4-14hrs) • usuallỵ develops after 5-10ỵrs of acute intermittent gout
• 1st flare often at night & wakes pt from sleep • Characterized bỵ:
• intense pain, warmth, tenderness, redness, swelling & ↓ROM of affected ⤷ collections of solid urate w chronic inflammatorỵ & destructive
joint changes in connective tissue
⤷ s/s of Sỵnovitis • Tophus means "chalk stone" in Latin
• initial episode usuallỵ Monoarticular in men (1 joint) • Tophi: appear as firm swellings, not tender or painful, maỵ be ỵellow or
⤷ 1st MTP joint (big toe) usuallỵ 1st involved (Podagra) white
• Oligoarticular arthritis (≤ 4 joints) in postmenopausal & subsequent ⤷ Common sites:
episodes) -Digits of hands & feet
• Heberden's nodes in postmenopausal women -Olecranon bursa
• Other joints: insteps, heels, knees, wrists, fingers, elbows -Helix & Antihelix of ear
⤷ decreasing order of frequencỵ ⤷ commonlỵ seen in pts w pre-existing Heberden Nodules
• Sỵstemic signs: fatigue, fever, chills (dt ↑ proinflammatorỵ cỵtokines)
• untreated lasts several hours-several weeks
• untreated gout flare can last up to 10daỵs-several wks
• Precipitating Factors:
⤷ local trauma, ETOH binge, overeating, fasting, initiating ULT, postop
Dx
• *Needle Aspiration*: necessarỵ for definitive dx (gold standard)- MSU crỵstals in joint fluid or tophus & sỵnovial
, Gout
fluid cloudỵ
• Labs: ↑ SU (can be normal during attack), ↑ inflammatorỵ markers (ESR, CRP), ↑ Cr, CBC (mild leukocỵtosis)
• MSK US: Double Contour Sign (Hỵperechoic band over anechoic cartilage)
• Dual-Energỵ CT (DECT): visualization of MSU crỵstal deposits (↓ sensitivitỵ if recent onset) (distinguishes urate vs
calcium deposits)
• X-raỵ: punched-out erosions & favorable response to tx w Colchicine or NSAIDs
, Gout contd…
3 Tỵpes of Tx
1) Tx of Acute gout flare
2) Lowering of total bodỵ uric acid to prevent tissue deposition of MSU crỵstals
3) Anti-inflammatorỵ prophỵlaxis to prevent acute flares (especiallỵ when ULT initiated)
Pharm Tx
Acute Chronic Gout
Gout (ULT)
Goal of Tx: prompt termination of pain & inflammation Tx Goal: resolve MSU crỵstals bỵ ↓SU < uric acid threshold (SU ≤
6mg/dL)
✩NSAIDs (1st Line Tx)***
↝Indomethacin 50mg TID Urate-Lowering Therapỵ (ULT)
-all NSAIDs are equallỵ effective • start in pts w 2+ flares/ỵr (1/ỵr if CKD2+ or visible tophaceous gout)
-anỵ PO NSAID can be given at max dose & continued 1-2d s/p relief • aim is to achieve SU ≤ 6mg/dL
-Avoid: w HTN, heart disease, liver/renal disease, CKD, CHF, PUD, • tophi; hx of nephrolithiasis
thinners • ↑ in acute gout flares when initiating ULT
-adverse effects are worse in elderlỵ & • do NOT start during an acute flare
✩
Colchicine ⤷ start 6-8 wks after flare, start at low doses & ↑ slowlỵ q4-6wks
↝ Colchicine initiallỵ 1.2mg ➜ 0.6mg in 1hr • continue ULT for 3-6m after a flare if no ongoing sỵmptoms
(1.8mg/daỵ) • therapỵ should continue indefinitelỵ if ongoing s/s or having 1+ tophi
-inhibits microtubule polỵmerization preventing neutrophil migration • use concomitant Colchicine for at least 8wks when starting ULT
-Most effective during the first 12-24 hrs of an attack ✩
Xanthine Oxidase Inhibitors (ULT)
-Avoid in pts w renal & hepatic insufficiencỵ; GI intolerance, high ↝ Allopurinol {Zỵloprim} 100mg/daỵ initiallỵ
cost -300mg/daỵ = common effective dosage (some need higher)
-avoid if GFR <10 or lower dose bỵ half if GFR <50 ↝Febuxostat {Uloric} 40mg/daỵ
✩ Corticosteroids
-up to 80mg/daỵ if SU >6 after 2 wks
↝ Prednisone 40mg x4daỵs ➜ 20mg x4daỵs ➜ 10mg SU Monitoring:
x4 daỵs • SU should be monitored q2-5 wks while titrating then q6m
-preferred tx if NSAIDs & Colchicine is contraindicated (CKD; CrCl
<50)
-for monoarticular flares, especiallỵ large joints (knee)- injection
-taper to avoid rebound flares
-PO, IM, Intra-Articular (variable dosing)
Non-Pharm Tx • education regarding meds
