  2. Initial presentation BG, a 11 1/2 years old active boy had an URI followed by right knee pain that got worse during the following 4 weeks to the point that he could not bend it. Over the last 2 weeks he also developed pain in both ankles, as well as swelling in right knee and ankles that made walking difficult, worst in the mornings. He complained of mild low back pain on the day of 1 st appointment. Parents reported a child previously active that was now quiet and still, very uncomfortable during the entire day. They gave him acetaminophen and ibuprofen once or twice a day, on and off pattern with little improvement. He is aA very good student that had missed 8 days of school in that month .

  3. ROS. No weight loss, no fever, no rashes, no respiratory or GI symptoms. Physical Exam . Weight above 75%, Height 50% BMI 21.9 (16.3-21.9) Vital signs normal , Severe swelling and pain in ankles, decrease ROM. Effusion in right knee with supra-patellar effusion Decrease ROM Schober 21 cm, No SI pain on pressure. Previous medical history : Perennial allergic rhinitis. Family history: Father Type II diabetes Grandmother Gastric CA

  4. Laboratory and other studies Labs : Rheumatoid Factor negative. WBC. 7.8: neut 46%, lymp 38 % mono 3% eos 8 ANA negative Hct. 34 % (low for Quito ‘s altitude) HLA-B27 negative 490K/uL platelets TNF 35 pg/m L (normal ≤ 8) ESR:18 mm/1hour AST and ALT normal. IgE: 89 IU Ophthalmologic exam with slit lamp: negative as well as each control every 6 months

  5. Initial Diagnosis: Oligoarticular JIA, ANA negative Treatment:  oral methotrexate in 6 weeks was switched to 12. 5mg SQ (GI complaints)  F olic acid, calcium  naproxen BID that over next 4 weeks once or twice a week.  Loratidine 5mg HS, do not replace the cat Disease course:  13 months later he still has morning stiffness and has received 3 times intra-articular glucocorticoids in his right knee.  Complaints once or twice a month of right hip pain. Normal MRI  With reluctant parents, Etanercept is started at 25mg/ week (0.48 mg/kg/week)  After week 4 the dose is increase to 50mg or 0.80 mg/kg / week  In 2 to 3 weeks no swelling, no pain and BG returned to his normal activities .  After 18 months without symptoms we started to decrease etanercept injection interval and then his dose was decreased to 25mg every 15 days, weaning period of 10 months.

  6. He had allergic rhinitis with poor compliance Complications …. for allergic medication, IgE 279 IU/mL 28 months after JIA diagnosis presented with sinusitis with high fever so immunomodulatory meds were stopped. He was supposed to reinitiate his methotrexate and Etanercept but failed to do so. Three months later started with red eye symptoms and used ophthalmic drops prescribed over the phone by general practitioner for allergic conjunctivitis. After four days of increasing pain, an ophthalmologic evaluation revealed severe uveitis with synechia in right eye. ANA negative with a SED rate of 20 mm/hr

  7. Treatment:  mydriatic cicloplegics topical and short course oral glucocorticoids,  Restart etanercept at 50mg SQ and methotrexate Wean off oral steroids over 3 weeks, and off eye drops in 8 weeks His TNF level slowly decreased to low levels over 6 months, although still higher than normal at 18-28 pg/mL Resolution of synechia with some decrease of visual acuity No synovitis, although a few episodes of hip pain, ultrasound studies normal, MRI of hips normal. Has been symptom free for 18 months.

  8. Summary of sequence of  11, 6 years diagnosed and started on MTX events  1 year with flares in knee, 3 courses of IA glucocorticoids  13 months after diagnosis started etanercept 25mg, increased dose in 4 weeks  Good control after 1 month  Symptom free for 18 months → weaning of etanercept up to 25mg every 15 days  26 months after diagnosis and 3 months after stopping etanercept and methotrexate develops for the first time unilateral acute uveítis without sinovitis or arthralgia or any other symptom.  Sinechiae resolved after 1 month of treatment, but pdecreased visión acutiy and remained with high TNF for 6 months after stopping glucocorticoesteroids

  9. Some themes to discuss When and how to decrease biologic medication after control of symptoms is apparent If uveitis is present, how should treatment and follow up be done? Acute vs Chronic change your approach? How common is an activation of JIA or JAS presented only with uveitis?

  10. Gracias Thank you! Muito Obrigada
