ARTHRITIS
RHEUMATOID ARTHRITIS found in synovial fluid of patients
with RA.
DEFINITION ● Stress

RISK FACTORS
● MC affected joints:
○ UE: wrist, MCP, PIP
○ LE: knee, ankle, foot
● Periods of immobilization
● Long term use of corticosteroids and
disease-modifying antirheumatic drugs
(DMARDS)
● Patients w/ RA have a 1.5-3 times greater
risk of osteoporotic fractures at the hip.
● Gene HLA-DRB1 on chromosome 6,
susceptibility to RA
PATHOPHYSIOLOGY
EPIDEMIOLOGY
● F> M (<40 y/o); M = F (65 y/o)
● Estimated prevalence of RA among adults
in the US is ~1.3M and its prevalence
increases with age.
ETIOLOGY
● Autoimmune disease of unknown
complex etiology.
● Genetic factors (increased risk and
clustering families)
○ Human Leukocyte Antigen–DR
isotype (HLA-DRB1) – strongest
genetic factor
● Infection
○ Epstein-Barr Virus (EBV) – The
virus with the strongest association
with risk for developing RA; Studies
linking EBV with RA have found
high levels of the virus in
lymphocytes that circulate in the
body. Additionally, EBV has been
