3. A Metabolic Disease Characterised By Recurrent
Attack Of Acute Inflammatory Arthritis Caused By
Elevated Levels Of Uric Acid In The Blood.
(Hyperuricemia)
Most Common Rheumatic Disease Of Adulthood.
The Uric Acid Crystallizes & Deposits In Joints,
Tendons, & Surrounding Tissues As Tophi.
Podagra Is A Painful Condition Of The Big Toe
Caused By Gout.
Mainly Affect Big Toe, Also Affects Knees, Ankle,
Wrists, Fingers, Elbow, Toes Of Feet.
4.
5. 2/3 of urate formed each day is excreted
by the kidneys & 1/3 from GI tract.
Normal adult excrete 500-700mg of uric
acid/day.
The Purine That A Person Eats & Also
Produced Naturally In Body, Are Metabolized
By The Body.
Liver Is The Major Site Which Breaks Down The
Purines & Produces A Waste Product Called
Uric Acid.
6. The Uric Acid Is Released Into The
Bloodstream & Eventually Filtered By The
Kidneys & Excreted In The Urine.
If Too Much Uric Acid Builds Up Can Form Into
Crystals That Deposit In Your Jts. & Cause
Pain & Inflammation.
7.
8. Elevated Uric Acid Can Occur From Over
Production Or Under Excretion Of Uric Acid
Over Production: (PRIMARY GOUT) 10-20%
• Less Common
• Genetic Abnormalities In Enzymes Related
Purine Metabolism
• ↓ Hypoxanthine-guanine Phosphorebosyl
Transferase(hgprt)
• ↑ Phosophoribosyl Pyrophosphate
Synthetase(prpp)
9. Under Excretion: (SECONDARY
GOUT) 80-90%
• More Common
• ↓ GFR
• Decline In Urinary Excretion Of Uric Acid
Can Determine By Measuring Urine Uric Acid
• >600mg/24hr Over Production
• <600mg/24hr Under Excretion
11. Serum Uate Abnormally High Without
Sign & Symptoms.
Male > 7mg/Dl
Female > 6mg/D
Not Life Threatening & Readily
Treatable.
Routine Prophylactic Rx Is Not
Required.
12. The Intervals Between Attacks Of
Gouty Arthritis Are Reffered To As
Intercritical Periods.
Intercritical Gout Simply Has Gout That
Has Caused Attacks Of Inflammation
In A Jts. In The Past But It Is Not Active
At The Time Evaluating The Pt.
13. Acute, Self Limiting, Monoarticular
Painful, Red, Hot, Swollen Accompained By
Fever, Raised ESR
Usually Resolved Within 2 Weeks If Untreated.
But Recurrent Attacks Are Followed By
Progressive Cartilage & Bone Erosion,
Deposition Of Tophi, Secondary OA, &
Disability Associated With Permanent Restriction
Of Jt. Fun.
May Occur Even If Serum Urate Is Normal
Ll>Ul
Also Present As Tenocynovitis, Bursitis, Cellulitis
14. Polyarticular Arthritis + Tophi Formation.
Articular Topheceous Gout May Results In
Destructive Arthropathy & Secondary OA.
Serum Urate Level > 7mg/Dl.
Disease Onset At Younger Age ≤ 40yrs.
Sites Of Tophi:
Digits Of Hands & Feet
Helix Of Ear
Bursa Around Elbow & Knee
Achilles Tendon
15. o age (>35yr)
o sex (m>f=3:1)
o obessity
o high blood pressure
o injury
o recent surgery
o foods / drinks
o medications(diuretics, levo-dopa,
salicylates, nicotinic acid, cyclosporine)
o genetics (SLC2A9 , SLC22A12, ABCG2)
o medical
conditions(hypothyrodism, dm, pso-
riasis, heart failure, renal transplant, chronic
renal insufficiency, coronary heart disease)
o high protein diet
o life style
16. o Sever Pain At Joint
o Redness & Inflammation
o Fever
o Less Flexibility
o Nodules
o Itchy & Peeling Skin Later
18. Lab. Diagnosis
• Evidence Of Monosodium Urate Crystals By Jt.
Aspiration For Definitive Diagnosis
Synovial Fluid Analysis- Arthrocentesis
• Blood Test- Check Serum Uric Acid Level
• Urine Test
Most Uric Acid Disolves In Blood & Travels To The Kidneys, Where It
Passes Out In Urine.
If Body Produces Too Much Uric Acid Or Dosen’t Remove Enough Of
It, Person Can Get Sick
25. A Seronegative Arthritis Found In Pts. With
Psoriasis.
It Is A Chronic Disease Charecterized By A
Form Of Inflammation Of The Skin & Jts.
Classified With Hla-b27 Genetic Factor
Associated Spondyloarthritis.
Immunologic Factor & Environmental Factor
Also Progress The Disease.
Males & Femaes Are Equally Affected
Peak Age Of Onset Between 30-55yrs.
26. Family history.
trauma, viral, bacterial
infection.
Signs & symptoms
Painful,Tendor,Swolloen Jts.
Hot red jts.-knee, ankle, feet
Fatigue, morning stiffness
Pitted nails, LBP
27. Gouty Arthritis
Ankylosing Spondyosis
Rheumatoid Arthritis
INVESTIGATIONS
Not Specific Diagnostic Test.
Elevation Of Esr.
Base On Clinical & Rdiological Basis.
28. New Bone Formation In Distal Jts.
Lysis Of Terminal Phalanges.
“ Pencil In Cup” Like Appearance.
