PathologyDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS27 A tophus is a foreign body reaction thatincludes the MSU crystals surrounded byfibrous tissue. 24. Clinical ManifestationsDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS28 Acute gout: acute arthritis ..most commonmanifestation 80% attacks..monoarticular and lowerextremities(MTPs, ankle and knee). Pain appears last, disappears first. Differential diagnosis : septic arthritis, cellulitis orthromboplebitis. Attacks subside in 3 to 10 days. Recurrent attacks .. involve more joints andusually persist longer. 25. Clinical ManifestationsDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS29 Intercritical gout: Asymptomatic periodbetween crises Duration .. varies, but untreatedpatients may have a second episodewithin two years. Some patients evolve to chronicpolyarticular gout without pain freeintercritical episodes. 26. Clinical ManifestationsDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS30 Chronic tophaceus Gout: The clinicalcharacteristic is the deposition of solidurate in the connective tissue. It is associated with early age of onset,long duration of untreated disease,frequent attacks, upper extremityinvolvement, polyarticular disease andelevated serum uric acid. 27. Clinical ManifestationsDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS31 Transplants with cyclosporine and/ordiuretics .. increased risk for tophaceusgout. Most common sites for tophi :olecranon, prepatellar bursa, ulnarsurface and Achilles tendon. 28.

Urate/gouty nephropathy Acute urate nephropathy Urate crystals renal tubules obstructive ARF DeH2O, low urine pH are precipitating factors Chronic urate nephropathy Urate crystals interstitium and renal medulla inflammation + surrounding fibrosis irreversible CRF Renal impairment can occur in ~40% in chronic gout Urate nephrolithiasis Stones flank pain/ureteric colic/hematuria Urate (radiolucent) / mixt. Calcium oxalate and/or calciumphosphate (radio-opaque) Contributing factors : hyperuricosuria, low urine output, acidicurine Urinary alkalinization (pot. Citrate or NaHCO3) dissolution of existing stones and prevention of recurrence 31. NephrolithiasisDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS35 The prevalence of nephrolithiasiscorrelates with the serum andurinary uric acid levels. Serum urate levels 13 mg/dl Urinary uric acid excretion > 1100mg/dwww.freelivedoctor.com 32. Diagnostic Tests Uric Acid: normal .. 4.0 to 8.6 mg/dl in men to 3.0Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS36to 5.9 mg/dl in women. Urinary levels are normal below 750mg/ 24h. Urinary levels above 750 mg/dl in 24h ingout or > 1100 mg/dl in asymptomatichyperuricemia indicates urateoverproduction. 33.

Uricosuric agentsProbenecid, sulfinpyrazone,benzbromaroneCan be used as second-line therapy for patients withunderexcretion of uric acid.Fluid intake should be increased/ urine pH maintainedabove 6 to prevent development of uric acid stones.Benzbromarone, a powerful uricosuric drug, is more activethan allopurinol taken at the maximum allowed dose forpatients with moderate renal failure.Hepatotoxic.Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS70 67. Uricosuric therapyDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS71 Probenecid blocks tubular reabsorption ofuric acid enhances urine uric acidexcretion increases urine uric acid level decreases serum uric acid level 68. Why Alkaline UrineDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS72 Uric acid is more soluble in urine than inwater. The pH of urine greatly influences itssolubility. pH 5 urine is saturated with uric acid atconcentrations ranging from 6 to 15mg/dl. At pH 7 saturation is reached atconcentration between 158 and 200mg/dl 69. Uricosuric therapyDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS73 moderately effective increases risk of nephrolithiasis not used in patients with renaldisease frequent, but mild, side effects some drugs reduce efficacy(e.g., aspirin) 70.

PSEUDOGOUTDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS97 Calcium pyrophosphate CrystalDeposition Disease (CPPD) is thesyndrome secondary to the calciumpyrophosphate in articular tissues. Includes: Chondrocalcinosis Chronic CPPD Pseudogout. 94. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS98 Etiology:Unknownsecondary to changes in the cartilagematrix or secondary to elevated levels ofcalcium or inorganic pyrophosphate. Pathology:CPPD crystals .. in joint capsule andfibrocartilaginous structures. Neutrophil infiltration and erosions. 95. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS99 Demographics: Predominantly elderly,peak age 65 to 75 years oldFemale predominance (F:M, 2-7:1). Prevalence.. 5 to 8% 96. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS100 Disease Associations: hyperthyroidsm, hypocalciuria,hypercalcemia, hemochromatosis,hemosiderosis, hypophosphatasia,hypomagnesemia, hypothyroidsm, gout,neuropathic joints, amyloidosis, traumaand OA. 97. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS101 Clinical Manifestations Pseudogout:Acute self-limited attacks resemblingacute gout.knee is involved in 50% of cases,followed by the wrist, shoulder, ankle,and elbow. 98. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS102 In 5% of patients gout can coexist withpseudogout. Diagnosis is confirmed with synovial fluidanalysis and/or the presence ofchondrocalcinosis in the radiographs. Acute Pseudogout primarily affects men. 99. PsedogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS103 Chronic CPPD: predominately affects women; Progressive, often symmetric, polyarthritis. Usually affects the knees, wrists, 2nd and 3rd MCPs,hips, spine, shoulders, elbows and ankles. Chronic CPPD differs from pseudogout in itschronicity, involvement of the spine and MCPs. 100. Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS104 101. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS105 Chondrocalcinosis: Generally is anincidental finding in XRays. Diagnostic Tests: Inflammatory cellcount in the synovial fluid. Rhomboidalor rodlike intracellular crystals. Imagingstudies reveal chondrocalcinosis usuallyin the knee, but can be seen in theradial joint, symphisis pubis andintervertebral discs. 102. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS106 Differential Diagnosis: Includes septicarthritis, gout, inflammatory OA,Rheumatoid Arthritis, neuropathicarthritis and HypertroficOsteoarthropathy. 103. Chondrocalcinosis: kneeCalcification of the menisci and articular cartilage that is typical ofchondrocalcinosis.Calcification is due to focal deposits of calcium pyrophosphate dihydratecrystals in articular cartilage.Classically, both knees (especially menisci) are involved, and thecalcifications, although linear, are not smooth and continuous but areinterrupted by multiple focal deposits.Statistically, the knee is the most frequent site of such calcification andattacks of pseudogout. However, other joints may be involved.Many patients with chondrocalcinosis on radiograph have not had clinicalattacks of pseudogout, and some patients with proven attacks of pseudogoutdo not have radiographic evidence of chondrocalcinosis on routine radiographs.Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS 104. Syndromes Associated withHydroxyapatite Acute monoarthritis (pseudopseudogout) Acute calcific tendinitis, bursitis Scleroderma, dermatomyositis Heterotopic calcification Milwaukee shoulder Crowned Dens SyndromeDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS108 105. Acute Apatite Monoarthritis(Pseudopseudogout)Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS109 Is usually a peri-arthritis. Intense inflammation (looks septic) Synovial fluid often non-inflammatory. Often causes podagra (especially inyounger women). Look for the telltale calcifications onradiographs. 106. Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS110 107. Milwaukee Shoulder Severe, destructive shoulder arthropathy. Seen in elderly females with DJD ofshoulder. High-riding humeral head on radiographs(large rotator cuff tear). Non-inflammatory fluid with BCP crystals.Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS111 108. Crowned dens syndromeDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS112 Is an association of acute cervical pain andcalcifications in the peri-odontoid space. This disease affects only adult females. Patients present with inflammatory signs, canbe treated with non-steroid anti-inflammatorydrugs and recover without sequela. CPPD deposition can also lead to thissyndrome. Radiologically - crowned dens. 109. Dr.Sandeep Agrawal,Agrasen Hospital,Gondia MS113 110. PseudogoutDr.Sandeep Agrawal,Agrasen Hospital,Gondia MS114 Therapy: It is similar to gout andincludes intrarticular corticosteroids.Colchicine can be used in acute attacksand also in prophylaxis. There is nospecific treatment for chronic CPPD. It isimportant to treat secondary causes andcolchicine could be helpful. 111. DISCLAMER115.This presentation is prepared for doctors in general..
