  35. 35. GOUT
  36. 36. Gout• Gout is a type of inflammatory arthritis induced by the deposition of monosodium urate crystals in synovial fluid and other tissues.• It is associated with hyperuricemia, which is defined as a serum urate level of 6.8 mg per deciliter or more.• In Population, 0.5% prevalence of gout overall
  37. 37. Risk Factor• Hyperuricemia – thiazide diuretics, cyclosporine, and low-dose aspirin (<1 g per day)• Triggers for recurrent flares include – recent diuretic use, alcohol intake, hospitalization, and surgery.• Urate-lowering therapy – which reduces the risk of gout attacks in the long term, can trigger attacks in the early period after its initiation
  38. 38. Pathophysiology
  39. 39. Classification of Gout Clinical category Cause Metabolic defect Primary gout (90% of cases) Enzyme defects unknown (85%-90% - Overproduction of uric acid of primary gout) - Normal excretion (majority) - Increased excretion (minority) - Normal production of uric acid - Under-excretion Known enzyme defects, e.g. partial - Overproduction of uric acid HGPRT deficiencySecondary gout (10% of cases) Associated with increased nucleic - Over production of uric acid with acid turnover, e.g. leukemia increased urinary excretion Chronic renal failure - Reduced excretion of uric acid with normal production Inborn errors of metabolism, e.g. - Overproduction of uric acid with complete HGPRT deficiency (Lesh- increased urinary excretion Nyhan syndrome)
  40. 40. Clinical PhaseAsymptomatic hyperuricemia Acute gouty arthritis Intercritical gout Chronic tophaceous gout

  42. 42. Diagnosis (Definite Dx)• synovial fluid or tophus aspiration with identification of • light microscopy ; needle shape crystal • compensated polarized light microscopy ; positive birefringence with negative elongation
  43. 43. Diagnosis (Presumptive Dx)• Medical Treatment with Colchicine improve within 12 - 24 hr• Criteria Diagnosis from American college of Rheumatology (6 in 12) – More than one attack of acute arthritis – Maximum inflammation developed within 1 day – Monoarthritis attack, redness observed over joints – First metatarsophalangeal joint painful or swollen – Unilateral first metatarsophalangeal joint attack – Unilateral tarsal joint attack – Tophus (confirmed or suspected) – Hyperuricaemia – Asymmetric swelling within a joint on x-ray film – Subcortical cyst without erosions on x-ray film – Joint culture negative for organism during attack.
  44. 44. Complication• Acute uric acid nephropathy – most commonly in patients treated with cytotoxic agents, especially for lymphoproliferative disorders and large tumour burdens• Chronic urate or gouty nephropathy – Accumulated in medullary interstitium induced inflammation process• Uric acid stone – Uric acid calculi constitute 10% of the renal stones
  45. 45. Management Acute gout attack• Aim of therapy for acute gout – rapid relief of pain and disability caused by intense inflammation.• Drug used – nonsteroidal antiinflammatory drugs (NSAIDs), colchicine, glucocorticoids, and possibly corticotropin.• Adjunctive treatment include – applying ice to and resting the affected joint.• NSAIDs and colchicine are first-line agents for acute attacks
  46. 46. What if treatment fails in acute gout ?• If there is no improvement in symptoms after 2–3 days: – Review the diagnosis, check compliance with medication, and encourage self-care strategies. – Increase the dose of medication to maximum and add paracetamol, with or without codeine.• If there is still no improvement in symptoms, try an alternative drug or consider combining treatment, or seek specialist advice.
  47. 47. What follow up is recommended after an acute attack of gout?• Follow up the person 4–6 weeks after an acute attack of gout has resolved, and: – Check the serum uric acid level. – Measure their blood pressure and take blood for fasting glucose, renal function, and lipid profile. – Identify underlying conditions such as hypertension, diabetes, or renal impairment, and assess the persons overall cardiovascular risk. – Assess and provide advice on risk factors such as obesity, diet, excessive alcohol consumption, and exercise. – Consider the need to start prophylactic medication if the person is having two or more attacks of gout in a year.
  48. 48. ManagementPatient with Hyperuricemia
  49. 49. Management Patient with Hyperuricemia• The purpose of lowering serum urate levels – To prevent acute flares and development of tophi• When treatment – Severity and frequency of flares, the presence of coexisting illnesses (including nephrolithiasis), and patient preference are additional considerations• Urate-lowering therapy – should not be initiated during acute attacks – started 2 to 4 weeks after flare resolution• The dose should be adjusted as necessary – maintain a serum urate level below 6 mg per deciliter which is associated with a reduced risk of recurrent attacks and tophi.
  50. 50. Management Patient with Hyperuricemia• How long for used Urate – lowering therapy – Suggest patient can keep uric acid level below 6.0 mg/dl and no attack at least 4-5 years – In Chronic tophaceous stage should stop when tophaceous gout resolve and continue for 4-5 years after resolution
  51. 51. Management Patient with Hyperuricemia• Flare Prophylaxis during Initiation of Urate-Lowering Therapy – general recommendation for flare prophylaxis is to use colchicine at a dose of 0.6 mg once or twice daily, with dose adjustments as needed for renal impairment – Diarrhea was common, resulting in a once- daily regimen of colchicine for many patients
  52. 52. CALCIUM PYROPHOSPHATE DEPOSITION DISEASE (CPPD)
  53. 53. Calcium pyrophosphate deposition disease (CPPD)• metabolic arthropathy caused by the deposition of calcium pyrophosphate dihydrate in and around joints, – especially in articular cartilage and fibrocartilage.• Although CPDD is often asymptomatic, with only radiographic changes seen – (ie, chondrocalcinosis)• various clinical manifestations may occur, including – acute (pseudogout) and chronic arthritis
  54. 54. Risk Factor• Age is most important risk factor• Osteoarthritis (OA) - threefold increased risk if CPPD present• Previous joint trauma/injury• Joint surgery/lavage promotes crystal shedding4• Metabolic disease – Hemochromatosis, 1˚Hyperparathroidism, Hypomagnesemia, Malabsorption syndromes – Consider in age <50-60 yo, especially if polyarticular chondrocalcinosis (CC)• Familial predisposition to CPPD
  55. 55. Clinical Presentation• Associated with both acute and chronic arthritis• Acute CPP crystal arthritis – inflammatory arthritis of one or more joints. Knees, wrists, shoulders, ankles, elbows, or hands can be affected.• chronic form of CPP arthritis – mimics osteoarthritis or rheumatoid arthritis and is associated with variable degrees of inflammation.• Typically occurs in older patients but can occur in younger patients with associated metabolic conditions, such as hyperparathyroidism and haemochromatosis.
  56. 56. Most common presentations of CPDDType A. PseudogoutType B. Pseudorheumatoid arthritisType C and D. PseudoosteoarthritisType E. Lanthenic or asymptomaticType F. Pseudoneuropathic jointOther :• ankylosing spondylytis or diffuse idiopathic skeletal hyperostosis (DISH)• pseudotophaceous disease
  57. 57. Diagnostic Criteria (Definite & Probable)• I. Demonstration of CPP crystals in tissues or synovial fluid – IIA. Identification of CPP crystals by morphological analysis using compensated polarising light microscopy. – IIB. Typical calcifications on x-rays (cartilage calcification); heavy punctuate or linear calcifications in fibro-cartilage, articular (hyaline) cartilage, or joint capsules.
  58. 58. Chrondocalcinosis
  59. 59. Chrondocalcinosis
  60. 60. Diagnostic Criteria (Possible)• IIIA. Acute arthritis, especially of the knee or other large joints.• IIIB. Chronic arthritis of the knee, hip, wrist, elbow, shoulder, or MCPs, particularly if accompanied by acute exacerbations, and if characterised by: – Involvement of uncommon sites for primary osteoarthritis – Radiographical appearance, including severe patellofemoral involvement – Subchondral cyst formation – Severe progressive joint degeneration with bony collapse – Variable and inconsistent osteophyte formation – Tendon calcifications, particularly of the Achilles, triceps, and obturator tendons – Axial skeletal involvement with subchondral cysts, disc calcification, and vacuum disc phenomena, as well as sacroiliac joint involvement.
  61. 61. Management (Acute attack)Ice and RestJoint aspirationOral Non steroidal Anti-inflammatory DrugsColchicineIntraarticular glucocorticosteroids (GCS)IV/IM/PO corticosteroid
  62. 62. Management (Long term / Chronic)• Prophylaxis against frequent recurrent acute attacks – Colchicine 0.6 mg twice daily – Low dose oral NSAIDs• Chronic CPP crystal inflammatory arthritis – Correct metabolic disease – Oral NSAIDs with gastro-protective treatment – Colchicine 0.5-1.0 mg daily – Daily low dose corticosteroids – Magnesium –a cofactor for enzymes that break down pyrophosphate – MTX / Hydroxychloroquine
  63. 63. CASE STUDY
  64. 64. Case #1• A 72-year-old woman presents with polyarticular joint pain.• She has long-standing mild joint pain, but over the last 10 years notes increasing discomfort in her wrists, shoulders, knees, and ankles. She has had several recent episodes of severe pain in 1 or 2 joints, with swelling and warmth of the affected areas. These episodes often last 3 to 4 weeks.• Her examination shows severe bony changes consistent with osteoarthritis in many joints, and slight swelling, warmth, and tenderness without erythema in the second and third MCP joints, left shoulder, and the right wrist.
  65. 65. Case #2• A 52-year-old woman presents with a 2-month history of bilateral hand and wrist pain, and swelling in her fingers.• She has also recently noted similar pain in the balls of her feet. She finds it hard to get going in the morning and feels stiff for hours after waking up. She also complains of increasing fatigue and is unable to turn on and off taps or use a keyboard at work without a significant amount of pain in her hands.• She denies any infections before or since her symptoms started.
  66. 66. Case #3• A 54-year-old man complains of severe pain and swelling in his right first toe that developed overnight. He is limping because of the pain and states that this is the most severe pain he has ever had (even covering my foot with the bed sheet hurts). He has had no previous episodes. His only medication is hydrochlorothiazide for hypertension. He drinks 2 to 3 beers a day. On examination, he is obese. There is swelling, erythema, warmth, and tenderness of the right first toe. There is also tenderness and warmth with mild swelling over the mid foot.
