Question what screening test will you send a 14 yo male teen with hla b 27 ve arthritis l.jpg
QUESTION to…What screening test will you send a 14 yo male teen withHLA B 27 +ve arthritis?

Consider hla b 27 associated aortitis and ar l.jpg
Consider HLA B 27 associated to…Aortitis and AR

  • HLA B27 is a risk factor for endocardial and myocardial damage in patients with B27-JA, even in the presence of only mild articular disease.

  • Patients with B27-JA should be screened by color-flow Doppler echocardiography for the presence of aortic regurgitation and myocardial inflammation with increased mitral blood flow velocity at atrial contraction due to impaired myocardial relaxation.

  • Regular monitoring may be required.

  • These patients might benefit from early pharmacologic intervention by afterload reduction (i.e., with ACE inhibitors). All patients with juvenile arthritis and

  • Endocarditis prophylaxis should be instituted when necessary.

Psoriatic arthritis l.jpg
Psoriatic Arthritis to…

  • Arthritis & psoriasis

    Or arthritis with at least two of the following:

Sausage digits

X-ray---Pencil-in-cup appearance

Pathogenesis l.jpg
Pathogenesis to…

Cytokine dysequilibrium -- increased IL-1, TNF

Increased inflammation, angiogenesis, cartilage degradation and joint destruction


Key concepts jia l.jpg

  • Characteristics NOT typically associated with the arthritis of JRA------severe pain, inability to weight bear, nocturnal wakening, and hot, erythematous joints.

  • Uveitis is the often asymptomatic inflammation of the uveal tract, most commonly seen in 20-30% of ANA positive, pauciarticular-JIA girls

  • Macrophage Activation Syndrome is a complication seen in systemic-JIA, resulting in DIC, encephalopathy, respiratory distress syndrome, renal failure and worsening serositis. Bone marrow biopsy may reveal the presence of histiocytes actively phagocytosing red cells and platelets

  • Ref: Mead Johnson Board Tutor

Remember l.jpg
Remember!!! to…

If a JRA patient has an autoantibody, it confers a worse prognosis

Pauci-JRA + ANA = uveitis risk

Poly-JRA + rheumatoid factor (RF) =erosive adult RA

(REF: Mead Johnson Board Tutor)

Management l.jpg
Management to…

Other immunosuppressive agents -risk of infection, liver and kidney function, blood counts, risk for cancer, risk for infertility, affects bladder

Prognosis l.jpg
Prognosis --4/11

  • Infections, steroid complications, atherosclerosis

  • New treatments and better survival

    • Survival has improved in the past 20 yrs

    • 10-year survival approaches 90%

    • Sepsis (severe life-threatening infection) is the commonest cause of death

  • Atherosclerosis

  • Important determinants: families’ ability to cope, socioeconomic status, compliance, teen-related issues, contraception
