•Complex protein molecules
•Created using molecular biology methods
• Produced in prokaryotic or eukaryotic cell cultures

TNF is a potent inflammatory cytokine
TNF is produced mainly by macrophages and
monocytes
TNF is a major contributor to the inflammatory and
destructive changes that occur in RA
Blockade of TNF results in a reduction in a
number of other pro-inflammatory cytokines (IL-1,
IL-6, & IL-8)

Most common childhood chronic disease
causing disability.
About 7/100,00 newly diagnosed children
with JIA per year.
 Prevalence about 1/1,000 children = 1,000
children in BC with JIA.
 7 subtypes.
Disease begins at any time during childhood
or adolescence.

To be considered JIA, onset must occur before 16 years of age.
JIA is heterogeneous: the presentation of the disease and its
natural history vary among individuals and over time.
The disease is typically classified into categories based on the
symptoms displayed and their severity.
Systemic arthritis
Oligoarthritis
Rheumatoid-factor positive (RF+) polyarthritis
Rheumatoid-factor negative (RF-) polyarthritis
Enthesitis-related arthritis
Psoriatic arthritis
Undifferentiated
G.ahrq.gov/dmardsjia.cfm.

Child under 16 years old
At least one joint with objective signs of arthritis:
›Swelling, or two of the following: pain with movement,
warmth of the joint, restricted movement, or tenderness
Duration of more than 6 weeks
Other causes have been excluded (ex. Infections, Lupus and other
connective tissue diseases, malignancies)

All kids with JIA have fevers.
All kids with JIA have rashes.
A child with joint pain (but no arthritis) must have JIA.
All arthritis is painful.
If a child has a positive rheumatoid factor, they must have
arthritis.
If x-rays are normal, there is no arthritis.

Heterogeneous group of diseases characterized by chronic
inflammatory processes involving the synovial
membrane, cartilage, and bone
The classification of JIA subgroups based on clinical and
laboratory characteristics including the number of affected joints
and the presence of autoimmune markers
Th1 cell-mediated disorder, driven by a population of T cells
producing inflammatory cytokines and chemokines

Joint pain, stiffness, and
swelling: These are the most
common symptoms of JRA,
but many children do not
recognize, or do not report,
pain. Stiffness and swelling
are likely to be more severe
in the morning.
Loss of joint function: Pain,
swelling, and stiffness may
impair joint function and
reduce range of motion.
Some children are able to
compensate in other ways
and display little, if any,
disability. Severe limitations
in motion lead to weakness
and decreased physical
function and sometimes to
invalidization.

Limp: A limp may
indicate a
particularly severe
case of JRA,
although it also may
be due to other
problems that have
nothing to do with
arthritis, such as an
injury. In JRA, a
limp often signals
knee involvement.

Eye irritation, pain, and
redness: These
symptoms are signs of
eye inflammation. The
eyes may be sensitive
to light. In many cases,
however, eye
inflammation has no
symptoms. If the
inflammation is very
severe and not
reversed, it can
cause loss of vision.
The most common
types of eye
inflammation in JRA are
uveitis and iritis. The
names refer to the part
of the eye that is
inflamed.

Recurrent fevers: Fever
is high and comes and
goes with no apparent
cause. Fever may
“spike” (go high) as
often as several times
in one day.
Rash: A light rash may
come and go without
explanation.

Myalgia (muscle
aches): This is
similar to that achy
feeling that comes
with the flu. It
usually affects
muscles throughout
the whole body, not
just one part.

Lymph node swelling. Swollen lymph nodes
are noticed most often in the neck and under
the jaw, above the clavicle, in the armpits, or
in the inguinal region.
Weight loss. This is common in children with
JRA. It may be due to the child’s simply not
feeling like eating.

Growth problems: Children
with JRA often grow more
slowly than average.
Growth may be unusually
fast or slow in an affected
joint, causing one arm or
leg to be longer than the
other. General growth
abnormalities may be
related to having a chronic
inflammatory condition such
as JRA or to the treatment,
especially glucocorticoids

ANA (antinuclear antibody)
RF (Rheumatoid factor )
CRP (C-reactive protein)
ESR (erythrocyte sedimentation rate)
CCP (Cyclic Citrullinated Peptide
Antibody) test

The goals: eliminate active disease, normalize
joint function, preserve normal growth, prevent
long-term joint damage, and prevent patient
disability
The American College of Rheumatology Pediatric
30 criteria (ACR Pedi 30) defines improvement as
involving at least 3 of 6 core set variables, with no
more than 1 of the remaining variables worsening
by > 30%.

The 6 core set includes
◦Physician global assessment
◦active joint count
◦number of joints with limited range of motion
◦Inflammatory markers
◦patient or parent assessments

•Treat acute flare rapidly with anti-
inflammatory agent
•Initiate urate-lowering therapy to
achieve sUA <6
•Use concomitant anti-inflammatory
prophylaxis for up to 6 mo to prevent
mobilization flares
INITIATE
(acute flare)
RESOLVE
(urate-lowering therapy)
139
•Continue urate lowering therapy
to control flares and avoid crystal
deposition
•Prophylaxis use for at least 3-6
months until sUA normalizes
MAINTAIN
(treatment to control sUA)

Rapidly end acute flares
Protect against future flares
Reduce chance of crystal inflammation
Prevent disease progression
Lower serum urate to deplete total body urate pool
Correct metabolic cause

Control inflammation & pain & resolve the flare
Not a cure
Crystals remain in joints
Don’t try to lower serum urate during a flare
Choice of med not as critical as alacrity & duration

NSAIDS
Colchicine
Corticosteroids

Colchicine- reduces pain, swelling, and
inflammation; pain subsides within 12 hrs and
relief occurs after 48 hrs
Prevent migration of neutrophils to joints

Side effects
Nausea
Vomiting
Diarrhea
Rahes

Colchicine :
Not as effective “late” in flare
Drug interaction : Statins, Macrolides,
Cyclosporine
Contraindicated in dialysis pt.s
Cautious use in : renal or liver dysfunction; active
infection, age > 70

The choice of pharmacologic agent depends on severity of the
attack
◦Monotherapy for mild/moderate attack
◦Combination therapy for severe attack or those refractory to
monotherapy
Acceptable combination therapy approaches include
◦Colchicine and NSAIDS
◦Oral steroids and colchicine
◦Intra-articular steroids with all other modalities
Continue current therapy during flare
Patient education on signs of flare for self treatment
146Kanna D, et al. Arthritis Care Res (Hoboken). 2012 Oct;64(10):1447-61

Rapidly end acute flares
Protect against future flares
Reduce chance of crystal inflammation
Prevent disease progression
Lower serum urate to deplete total body urate
pool

Hyperuricemia ≠ Gout
Goal sUA < 6
Use prophylaxis for at least 3 months after
initiating gout therapy
Do not stop gout medication unless patient is
showing evidence of drug toxicity or adverse
reaction
Ask your friendly rheumatologist for help!

Colchicine : 0.5-1.0 mg/day
Low-dose NSAIDS
Both decrease freq & severity of flares
Prevent flares with start of urate-lowering RX
Best with 6 mos of concommitant RX
Won’t stop destructive aspects of gout

Rapidly end acute flares
Protect against future flares
Reduce chance of crystal inflammation
Prevent disease progression
Lower serum urate to deplete total body urate
pool

RX is lifelong & continuous
MED choices :
Uricosuric agents
Xanthine oxidase inhibitor

Probenecid, (Losartan & fenofibrate for mild
disease)
Increased secretion of urate into urine
Reverses most common physiologic abnormality
in gout ( 90% pt.s are underexcretors)

Patients taking uricosuric agents are at risk for
urolithiasis. This can be decreased by ensuring
high urinary output and by adding sodium
bicarbonate 1 gram TID.
The available agents include: probenecid (1-2
g/day) and sulfinpyrazone (50-400 mg BID).
Dose should be increased to decrease uric acid <
6.0 mg/ml

Allopurinol :
Blocks conversion of hypoxanthine to uric acid
Effective in overproducers
May be effective in underexcretors
Can work in pt.s with renal insufficiency

Allopurinol decreases uric acid in overproducers
and underexcreters; it is also indicated in patients
with a history of urolithiasis, tophaceus gout, renal
insufficiency and in prophylaxis of tumor lysis
syndrome.

Allopurinol: usual dose is 300 mg/day. Maximal
recommended dose is 800 mg/day.
In renal insufficiency dose should be decreased to
200 mg/day for creatinine clearance < 60ml/min
and to 100 mg/day if clearance < 30 ml/min).

Start with small doses of allopurinol to reduce the
risk of precipitating an acute gout attack.
Most common side effects are rash (2% of
patients) but rarely patients can develop
exfoliative dermatitis that can be lethal.
Chronic use of colchicine (0.6-1.2 mg/day) is used
as prophylaxis for acute attacks.

Calcium pyrophosphate Crystal Deposition
Disease (CPPD) is the syndrome secondary to the
calcium pyrophosphate in articular tissues.
This includes: Chondrocalcinosis, Chronic CPPD
and Pseudogout.

Etiology: It is unknown, but can be secondary to
changes in the cartilage matrix or secondary to
elevated levels of calcium or inorganic
pyrophosphate.
Pathology: CPPD crystals are found in the joint
capsule and fibrocartilaginous structures. There is
neutrophil infiltration and erosions.

Demographics: It is predominantly a disease of
the elderly, peak age 65 to 75 years old. It has
female predominance (F:M, 2-7:1).
Prevalence of chondrocalcinosis is 5 to 8% in the
general population.

Disease Associations: hyperthyroidsm,
hypocalciuria, hypercalcemia, hemochromatosis,
hemosiderosis, hypophosphatasia,
hypomagnesemia, hypothyroidsm, gout,
neuropathic joints, amyloidosis, trauma and OA.

Clinical Manifestations
Pseudogout: Usually presents with acute self-
limited attacks resembling acute gout. The knee
is involved in 50% of the cases, followed by the
wrist, shoulder, ankle, and elbow.

In 5% of patients gout can coexist with
pseudogout.
The diagnosis is confirmed with the synovial fluid
analysis and/or the presence of chondrocalcinosis
in the radiographs.
Acute Pseudogout primarily affects men.

Chondrocalcinosis: Generally is an incidental
finding in XRays.
Diagnostic Tests: Inflammatory cell count in the
synovial fluid. Rhomboidal or rodlike intracellular
crystals. Imaging studies reveal
chondrocalcinosis usually in the knee, but can be
seen in the radial joint, symphisis pubis and
intervertebral discs.

Chronic CPPD: predominately affects women; it is
a progressive, often symmetric, polyarthritis.
Usually affects the knees, wrists, 2nd and 3rd
MCP’s, hips, spine, shoulders, elbows and ankles.
Chronic CPPD differs from pseudogout in its
chronicity, involvement of the spine and MCP’s.

Differential Diagnosis: Includes septic arthritis,
gout, inflammatory OA, Rheumatoid Arthritis,
neuropathic arthritis and Hypertrofic
Osteoarthropathy.

Therapy: It is similar to gout and includes
intrarticular corticosteroids. Colchicine can be
used in acute attacks and also in prophylaxis.
There is no specific treatment for chronic CPPD. It
is important to treat secondary causes and
colchicine could be helpful.

Affects men & women equally
Occurs in 4-6% up to 30% of patients with known
psoriasis
◦60 – 70%: Skin psoriasis first
◦15%: Psoriatic arthritis first
◦15%: Skin and arthritis diagnosed at same time

Prevalence of psoriasis in the general
population: 0.1-2.8%.
Prevalence of psoriasis in arthritis patients:
2.6-7.0%.
Prevalence of arthritis in the general
population: 2-3%.
Prevalence of arthritis in psoriatic patients: 6-
42%.
Epidemiological Evidence

Morning stiffness lasting >30 min in 50% of patients
1
Ridging, pitting of nails, onycholysis – up 90% of patients vs
nail changes in only 40% of psoriasis cases
2,3
Patients may present with less joint tenderness than is usually
seen in RA
1
Dactylitis may be noted in >40% of patients
2,4
Eye inflammation (conjunctivitis, iritis, or uveitis) — 7–33% of
cases; uveitis shows a greater tendency to be bilateral and
chronic when compared to AS
2
Distal extremity swelling with pitting edema has been reported
in 20% of patients as the first isolated manifestation of PsA

Entheses are the regions at
which a tendon, ligament, or
joint capsule attaches to
bone
1
Inflammation at the
entheses is called enthesitis
and is a hallmark feature of
PsA
1,2
Pathogenesis of enthesitis
has yet to be fully
elucidated
2
Isolated peripheral
enthesitis may be the only
rheumatologic sign of PsA
in a subset of patients

2). It is synovial or chondropathic
3).if polyarticular, specific distribution and
pattern
4). Sacroiliac and CVJ etc.
5). Clinical presentation (history)

Any monoarticular synovial jt. Involvement is
assumed to be infective unless proved
otherwise.
Any monoarticular chondropathic jt. is
considered as degenerative.
Polyarticular jt. Involvement s/o inflammatory
noninfective etiology.

Synovial arthropathy:
1). Periarticular osteopenia
2). Jt. Space effusion (soft tissue)
3). Erosions
4). Loss of jt. space (late feature)
