12. Rheumatoid Arthritis
• Commonest inflammatory joint disease seen in
clinical practice affecting approx 1%-3% of
population.
• Chronic multisystem disease of unknown cause.
• Characterized by persistent inflammatory synovitis
leading to cartilage damage, bone erosions, joint
deformity and disability.
13. Onset
• Although Rheumatoid arthritis may present at any
age, patients most commonly are first affected in the
third to sixth decades.
• Female: male 3:1
• Initial pattern of joint involvement could be:-
1) Polyarticular : most common
2) Oligo articular
3) Monoarticular
• Morning joint stiffness > 1 hour and easing with
physical activity is characteristic.
• Small joints of hand and feet are typically involved.
14. Pathogenesis of RA
• Strong associations between HLA-DR4(shared
epitope) and RA.
• HLA class II(APCs) surface antigens of immune
cells(B- lymphocytes, macrophages, dendritic cells).
• APC/T-cell interaction leads local inflammatory
response.
• Secretion of IL1,IL6,TNF, cytokines,PG leads to
synovitis.
• activation of osteoclast and chondrocytes-
>formation of inflammatory granulation tissue
named pannus->destruction of cartilage and bone-
>deformity of joint.
16. Clinical manifestation
• Pre-clinical stage: muscle pain,tiredness,loss of
weight and generalized lack of well being.
• In early stage :
pictures of polysynovitis - pain, swelling, stiffness of
MCP,PIP joints then to wrist, feet, knee, shoulder.
Tenosynovitis –wrist extensors, finger flexors common
Morning stiffness >1hr.
If Large joint involves: local warmth, synovial
hypertrophy,effusion,restrited movements.
17. In later stage
• Deformity become apparent.
• Acute pain of synovitis replaced by constant
ache pain of joint destruction.
• Joint instability and tendon rupture.
• Rheumatoid deformities.
• Restricted movements of joints.
• 1/3 rd patient pain and stiffness in cervical
spine.
27. Rheumatoid Factor (RF)
• Antibodies that recognize Fc portion of IgG(70%).
• Can be IgM , IgG , IgA.
• clinical practice, IgM RF is usually measured(on
methodology).
• 85% of patients with RA over the first 2 years become
RF+.
• A negative RF may be repeated 4-6 monthly for the first
two year.
• PROGNISTIC VALUE-High titres of RF, tend to have
POOR PROGNOSIS, more extra articular manifestation.
28. Causes of positive test for RF
Rheumatoid arthritis(overall) 70%
Rheumatoid arthritis with nodules and extra-articular manifestations. 100%
Sjogrens syndrome 90%
Cryoglobulinemia 90%
Chronic liver disease 50%
Infective endocarditis 40%
SLE, Leprosy, Syphilis 30%
Tuberculosis 15%
Malignancy, Age>65 Yrs 20%
Normal Healthy People 5%
29. Anti Cyclic Citrullinated Peptide Antibodies
• peptidylarginine deiminase, an enzyme abundant in
inflamed synovium.
• IgG against synovial membrane peptides damaged via
inflammation.
• Anti-ccp Antibody have similar sensitivity to RF for RA
(70%) but much higher specificity (> 95%).
• Both diagnostic & prognostic value
• Predictive of Erosive Disease
– Disease severity
– Radiologic progression
– Poor functional outcomes
35. ACR Criteria (1987)
1.Morning Stiffness ≥1 hour.
2.Arthritis of ≥ 3 joints observed by physician.
3.Arthritis of hand joints- PIP, MCP, wrist
4. Symmetric arthritis

7. Radiographic Erosions or periarticular
osteopenia in hand or wrist joints
• Criteria 1-4 must be present for ≥6 wks
• Must have ≥4 criteria to meet diagnosis of RA
36. 2010 ACR/EULAR Classification Criteria

damage
• Prevent deformity
39. Treatment modalities for RA
NSAIDS
Steroids
DMARDs
Immunosuppressiv
e therapy
Biological
therapies
Surgery
40. NSAIDS
for symptom control
1) Reduce pain and swelling by inhibiting COX
2) Do not alter course of the disease.
3) Chronic use should be minimized.
4) Most common side effect related to GI tract.
41. Corticosteroids in RA
• Indications for systemic steroids are:-
1. For treatment of rheumatoid flares.
2. For extra-articular RA like rheumatoid vasculitis
and interstitial lung disease.
3. As bridge therapy for 6-8 weeks before the
action of DMARDs begin.
4. Maintenance dose of 10mg or less of
Prednisolone daily in patients with active RA.
5. Sometimes in pregnancy when other DMARDs
cannot be used.
42. Disease Modifying Anti-rheumatic Agents
• Drugs that actually alter the disease course .
• Should be used as soon as diagnosis is
made.
• Appearance of benefit delayed for weeks to
months.
• NSAIDS must be continued with them until
true remission is achieved .
• Induction of true remission is unusual .

45. When & what DMARDs
• Rheumatologists start DMARDs from Day
1.
• METHOTREXATE is the DMARD of choice,
most widely prescribed in the world.
• DMARD combination is specially effective
if they include Methotrexate as an anchor
drug.
46. Limitations of conventional DMARDs
1) The onset of action takes several months.
2) The remission induced in many cases is partial.
3) There may be substantial toxicity which
requires careful monitoring.
4) DMARDs have a tendency to lose effectiveness
with time-(slip out).
These drawbacks have made researchers look
for alternative treatment strategies for RA- The
Biologic Response Modifiers.
47. BIOLOGICS IN RA
• Cytokines such as TNF-α ,IL-1,IL-10 etc. are key
mediators of immune function in RA and have
been major targets of therapeutic manipulations in
RA.
• Various biological approved in RA are:-
1) Anti TNF agents : Infliximab Etanercept Adalimumab
2) IL-1 receptor antagonist : Anakinra
3) IL-6 receptor antagonist : Tocilizumab
4) Anti CD20 antibody : Rituximab
5) T cell co stimulatory inhibitor : Abatacept
48. How to monitor Tt in RA?
• Disease activity is assesed by several parameters…
duration of morning stiffness, tender joint count,
swollen joint count, observer global assessment,
patient global assessment, visual analogue scale for
pain, health assessment questionnaire,ESR,NSAID
pill count,DAS score etc..
• Patient on MTX,SSZ or leflunamide show clinical
improvement in 6-8 wks.
• Patient should be observed for 6 months before
declaring a DMARD ineffective.
50. Surgical Approaches
• Increases function
of the joint
• Decreases pain
and inflammation
• Beneficial as an
early treatment
option
• Not a cure!
Synovectomy
56. Ankylosing Spondylitis
• AS is a chronic, progressive immune-mediated
inflammatory disorder that results in ankylosis
of the vertebral column and sacroiliac joints.
• Complete fusion results in a complete rigidity
of the spine, a condition known as bamboo
spine.
57. Cont…
• Over time, joints in
the spine can fuse
together and cause a
fixed, bent-forward
posture.
• HLA-B27 gene is
associated with AS.
• Age of onset typically
between 15 and 35
years.
• M:F= 3:1
58. Age at Onset Distribution of AS and
Rheumatoid Arthritis (RA)
60. CONT..
• Continued inflammation
of the:
-ligaments,
-tendons,
-joint capsules (soft
tissues surrounding the
joint),
-and joints of the spine -
cause the spine to fuse
together (ankylose) as the
joints and disc spaces are
replaced by bone.
61. Clinical features
• Axial manifestations:
Chronic low back pain, With or without buttock pain.
Morning stiffness, relief with activity.
Limited axial motion.
Axial deformity.
• Extra skeletal manifestations:
Anorexia,malaise,weight loss,fatigue,low fever,
Difficulty in respiration.
Iridocyclitis
Vasculitis.
62. Peripheral manifestations
Enthesitis Peripheral arthritis Dactylitis
AS: Signs and Symptoms
50% patients with
enthesitis
Up to 58% patients
ever had arthritis
Much smaller number
of patients
63. Investigations:
• a blood test for the HLA-
B27 gene.
• X-ray
-which show
characteristic spinal
changes and Sacroiliitis.
• tomography and magnetic
resonance imaging of the
sacroiliac joints.
65. THE ROME CRITERIA

• treatments and medications are available to
reduce symptoms and pain.
• three major types of medications used.
NSAIDS.
DMARDS.
Immunosuppressive.
TNF blockers: infliximab,atenarcept etc.
69. Surgical Management:
• may include OSTEOTOMY for marked deformities
of the hip/spine.
• occasionally, hip or knee ARTHROPLASTY is used.
- if there is severe arthritis of those joints.
Nursing Responsibilities:
• Baseline ROM and chest expansion exercise.
• proper positioning at rest is essential.
• the mattress should be firm, and pillows must be
avoided.
71. Reactive Arthritis/Reiter”s Syndrome
• Reactive arthritis or Reiter’s syndrome is a
acute,painful,asymmetrical form of inflammatory
arthritis that develops in reaction to an infection
by bacteria or virus.
• a triad of nongonococcal urethritis, conjunctivitis, and
arthritis.
• RF-seronegative, HLA-B27-linked arthritis.
• The arthritis may be “Additive or Migratory.”
73. Signs and symptoms
• Dysuria,an increased frequency of urination.
• Prostatitis,cervicitis, salpingitis,vulvovaginitis
• penile lesions called balanitis circinata.
• inflammation of the eyes in the form of
conjunctivitis or uveitis
74. •Swelling, pain in large joint, knee etc
•Keratoderma blennorrhagica
•Palms/soles
•Oral ulcers (usually shallow and painless)
•Inflammatory back pain (50% of patients)
•Enthesitis (40%)
•Dactylitis (40%)
75. Treatment
• The main goal of treatment is to identify and
eradicate the underlying infectious source with
the appropriate antibiotics if still present.
• Otherwise, treatment is symptomatic for each
problem.
• Analgesics particularly NSAIDs, sulfasalazine,
steroids .
• immunosuppressants may be needed for
patients with severe reactive symptoms that do
not respond to any other treatment.
76. Psoriatic arthritis
• A chronic inflammatory arthritis in association with skin
psoriasis(7%-45%).
• Characterized by osteolysis and bony proliferation.
• Males and females are equally affected.
• Range from mild nondestructive disease to a severely rapid
and destructive arthropathy.
• HLA B27 associated & Seronegative.
• Characterized by synovitis, Enthesitis, dactylitis, spondylitis,
skin and nail psoriasis.
82. CASPAR Criteria For Diagnosis

CD8 T cells
• Tumor necrosis factor antagonists
– Infliximab: a monoclonal antibody that binds to
TNF and inhibits binding of TNF to its receptor
– Etanercept: similar emchanism to infliximab
• For axial arthritis, exercises to maintain
posture and flexibility
87. Systemic erythematosus Lupus
• Immune complex deposition disease, involving
many organs.
• Arthritis: Nonserosive 2 or > joints
