  1. Advances in identifying genetic and non-genetic risk factors of rheumatoid arthritis Jessica Larson Advisor: Sam Powdrill, PA-C

  2. Objectives • Review of epidemiology & pathophysiology of RA • Understand functional impairment • Learn risk factors that determine the onset & severity in development of RA • Pre-RA red flags • How to advise patient in clinic to reduce or prolong outcome of RA

  3. Epidemiology • Most common inflammatory polyarthritis • One percent or 2.1 million adults in US • Women 2-3x more affected than men • Age of onset is 40-60 years old • Smokers 4x more likely to develop • First-degree relative prevalence rate is 2-3x more like to develop • Mortality is higher, in severe RA mortality approaches that of CHF or Hodgkin disease

  4. Pathophysiology Review http://www.hopkins-arthritis.org/rheumatoid/rheum_clin_path.html#preven

  12. Risk Factors

  13. GENETIC HLA - DR complex DR-1 & DR-4 NIMA & NIPA HLA - I kappa BL NON-GENETIC Smoking Neuroendocrine imbalances: Low sex hormones Low cortisol levels Vascular endothelial alterations in men Immunologic markers Risk Factors

  14. Pre-RA red flags CCP antibody immunological markers appear many years (as many as 12) before onset of RA with increased risks if: • Smoking (>20 pack-years) • Coffee consumption (>10 cups/day) • Ever use of oral contraceptives • First-degree relative of schizophrenia • Obesity (3x risk) • Age of menarche >15 years old (2x risk)

  15. What can PAs do? • If there is a family history of RA, it is especially important to NOT SMOKE • Anti-CCP test is a blood test that can be ordered by the PA • RF is ~81-87% specific post-onset • CCP is ~96% specific and available earlier • Tell them to stay active and loose weight
