 No rash
 No weight loss
 No other joints are involved
 CBC and differential within range

 1-5 years of age
 Girls > boys
 Arthritis in ≤ four joints
 Large joints-knees, ankles, elbows

 Girls > boys
 Bimodal peaks: 2-5 years & 10-14 years
 Insidious onset, sometimes acute, with progressive involvement of >/=5 joints in
the first 6 months
 In younger children, onset is usually pauciarticular
 AM stiffness and fatigue
 May have low-grade fever

 Small joints of hands & feet
 Tenosynovitis of flexor tendon sheaths
PoJIA
 Labs - normal or suggest an inflammatory state
 Anemia
 High ESR
 Hypergammaglobulinemia
 Leukocytosis
 5-10% RF +
 40-50 % ANA + [Cassidy, 2001]
 Late-onset PoJIA
 Subset of RF+ girls mimics adult RA
 Chronic course into adulthood
PoJIA-Differential diagnosis
 Infectious causes of polyarthritis
 Viral
 Septic
 Lyme
 Other
 Serum sickness
 Other rheumatic diseases
 Inflammatory Bowel Disease (IBD)
 Systemic Lupus Erythematosis (SLE)

Guarded prognosis
Poorer prognosis
Adolescent girls RF+ with late-onset, rapidly progressive erosive arthritis –often
have RA like disease as adults
Early involvement of small joints of hands & feet
Persistent inflammation
Subcutaneous nodules
RF +
Destructive hip disease among other joints & eventual disability
Contractures & ankylosis
Short stature (more in children)
Often require joint replacements
Chronic uveitis – 5%
SoJIA- Course & Complications
 Systemic features may persist for 4-6 months with varying degrees of joint
involvement
 Prognosis
 Complete recovery
 Polyarticular pattern
 Persistent inflammation &/ or chronic destructive arthritis
 Long standing SoJIA
 Micrognathia, c-spine fusion and destructive hip disease
 Short stature & FTT
 Uveitis - rare
 Amyloidosis -rare in the US
 Macrophage Activation Syndrome

Enthesitis-related arthritis /Spondyloarthropathy
Commonly complain of:
 Pain in the back & heel
 Morning stiffness
 Arthritis & /or enthesitis with any 2 of the following:
 Sacroiliac joint tenderness, Inflammatory spinal pain or both
 Positive family history
 Acute anterior uveitis
 Arthritis onset in boys > 8 yrs
 HLA-B 27 (higher likelihood of developing debilitating ankylosing spondylitis)
Pathogenesis of JIA
 Cytokine dysequilibrium -- increased IL-1, TNF

Management
 NSAIDS
 Disease Modifying Agents (DRUGS)
 Joint Replacement
 Physical and Occupation therapy
 Ophthalmologic monitoring
L. Nandini Moorthy, MD MS
Handout- Peds Rheumatology

Social support, education and family counseling
NSAIDS
 Naproxen
 Nabumetone
 Diclofenac
 Indomethacin
 Ibuprofen, Naprosyn and Tolmentin are approved for children
 Used for all types
 Usually sufficient for PaJIA, mild spondyloarthropathy & mild cases of other
types.
 Follow LFTs, UA
 Watch for GI, skin and psychiatric symptoms
Disease Modifying Anti-Rheumatic Drugs (DMARD) or
Slow Acting Anti-Rheumatic Drugs (SAARDS)
 Cyclophosphamide
 Leflunamide (Arava)
 Thalidomide-in SoJIA
 Tacrolimus
 Novel Biologics
 Gold
 Autologous bone marrow transplantation –in severe cases of SoJIA
 Monitor- LFTs, CBC, UA, BP, neuropathy
 NOVEL BIOLOGICS
 Anti-TNF agents
 Etanercept is a recombinant fusion dimeric protein (sTNFR)
 Infliximab -Monoclonal Anti-TNF antibody (has murine componenmt)
 Combination of Etanercept and Methotrexate
 Adalimumab (Humira): Fully humanized TNF alpha Mab with human derived
heavy and light chain variable regions and human IgG constant regions.
 Anakinra (Kineret): IL-1 Receptor antagonist blocks cellular activation
 Anti-IL-6R ab: Anti-IL-6 receptor antibody prevents the formation of IL-6/IL-6R
complex and eventually inhibits the function of IL-6 in children with SoJIA
 Adverse events
Cases 3, 4 and 5: The swollen joint
 All three children have an unremarkable exam except for arthritis
 Complete blood count and differential, electrolytes, blood urea nitrogen,
creatinine, and urine analysis are within normal limits
 Erythrocyte sedimentation rate range from 30-40 mm/hour
 The X-rays of the respective joints show only soft tissue swelling
 They were all started on non-steroidal anti-inflammatory drugs
 Diagnosis and management
 Patient 3 tested positive for Lyme Western Blot IgG; Treated with oral
Doxycycline for Lyme disease.
 Patient 4 had elevated Antistreptolysin-O titre and anti-strep-DNAse B
antibodies and had normal electrocardiogram and echocardiogram; Started on
oral Penicillin treatment and prophylaxis for Post-Streptococcal Reactive Arthritis.

 PREVENT ACUTE MORBIDITY, MORTALITY
L. Nandini Moorthy, MD MS


o Coronary aneurysms
o Peripheral gangrene
o Myocardial infarct
PREVENT CHRONIC MORBIDITY
THERAPY
 ASA 80 to 100 mg/kg per day in 4 doses with IVIG for 3-14 days
 High-dose ASA and IVIG appear to possess an additive anti-inflammatory effect.
 Low-dose ASA (3 to 5 mg/kg per day) until no evidence of coronary changes
 For children with coronary abnormalities, aspirin may be continued indefinitely
 Naproxen
 IVIG (2 g/kg) with aspirin (50–80–100 mg/kg) given within 10 days of fever onset
 Second infusion of IVIG (2 g/kg) in addition to high-dose aspirin is strongly
recommended in all children with persistent or recurrent fever
 How to treat the small group (3–4%) still remaining febrile?
 Either a third dose of IVIG (2 g/kg)
 Corticosteroids
 Cyclophosphamide, cyclosporin and ulinastatin
 Anti-TNF agents (Infliximab)
