1/3rd of All Primary Care Visits Involve a Musculoskeletal Complaint.
Do You See Patients with Joint and Muscle Aches and Pains?DO YOU ALWAYS FEEL COMFORTABLE TRIAGING THESE PATIENTS?
Common Arthritis Questions• Is it inflammatory arthritis ?
• Distinguishing RA from OA
• What does this + ANA mean?• Distinguishing CTD from chronic pain and fibromyalgia
Case 1DISTINGUISHING INFLAMMATORY ARTHRITIS FROM OSTEOARTHRITIS
Case 1: The Reluctant Contractor67 yo Male Contractor• Previous hx of LBP, neck pain
chronic plantar fasciitis• 2 yrs previous, pneumonia, Rx included prednisone. Joints felt
wonderful. • 2+ yrs of polyarthralgia, 3 ibuprofen QID, otherwise too stiff to
get out of bed• No F/C/S, no wt loss. No rash or sun sensitivity, no dry eyes, eye
inflammation, pleurisy, SOB, Cough, or GI distress. No numbness, Raynauds. No hx STD, kidney stones or gout. No hx of cancer, recent infection.
• Dad with seropositive RA • Pain score 6, AM stiff 10 min
What features of the Patient History suggest inflammatory polyarthritis? A. 10 min of morning stiffness
B. Hx of Back pain and plantar fasciitis?
C. Trial of prednisone made everything better
D. Needs 12 ibuprofen a day, or too stiff to get out of bed and dad had rheumatoid arthritis
DDx of Polyarticular Pain• Polyarthritis: Chronic and Acute (viral)• Reactive arthritis• Fibromyalgia• Multiple site Bursitis/Tendonitis• Hypothyroidism• Metastasis• Depression• Neuropathic pain• Metabolic/inherited bone diseases (osteomalacia, osteogenesis
imperfecta)
“The evaluation of the adult with polyarticular pain”Shmerling RH, ed Wolters Kluwer, May 2018
Case 1 Physical Exam• Rapid 3 = 7.5• Moderate OA hands, 1st and
3rd MCPS, 1st CMCs, AC joints, L knee, B PF joints, toes
• Bilateral Rotator cuff dysfunction
• Normal Achilles, No sausage digits
• Normal L-spine motion (finger to floor distance 2 inches)
• 17 swollen, 20 tender joints
Can you tell if a joint is swollen?
• Yes• No
Case 1LAB AND X-RAY RESULTS
• Normal: CBC, ESR, CRP, Chemistries, urine
• -RF, -CCP, - ANA
• X-ray hands C/W osteoarthritis, Moderate (nodal pattern)
Rheumatoid Arthritis:Radiographic Abnormalities
• Soft tissue swelling
• Symmetric joint involvement
• Peri-articular osteoporosis
• Symmetric joint space narrowing
• Marginal erosions
• Deformity – Fibrous ankylosis
Question
Does this 67 yo Male Contractor have inflammatory Arthritis?A. Yes
B. No
The Case for Inflammatory Arthritis • SX > 6 weeks
• Prolonged AM stiffness
• SX better with ibuprofen
• + family hx of Sero+ RA
• 17 Swollen joints on PE
The Case Against Inflammatory Arthritis• Patient is 67 yo, and a laborer with lots of OA
• No CTD disease features
• No inflammatory bowel sx
• No psoriasis
• No STD risks, no Gout/stone
• Normal ESR, CRP
• Negative ANA, RF, CCP
• X-rays show osteoarthritis without erosions, Ca++, etc
Does Negative RF, CCP, Normal ESRAffect Your DecisionA. YES
B. NO
The Key: SYNOVITIS
Rheumatoid Arthritis Osteoarthritis
Laboratory Testing to Discriminate Between RA and Non-RA in Patients With Early Arthritis

*Anti-CCP and IgM RF were determined by enzyme-linked immunosorbent assay (ELISA).CCP = cyclic citrullinated protein; PPV = positive predictive value; NPV = negative predictive value. Visser H, et al. Best Pract Res Clin Rheum. 2005;19:52–72.

Characteristics at Baseline
Characteristics at Month 3
SE = possession of ≥ 1 allele of shared epitope (HLA-DR1,4,10); UPA = undifferentiated polyarthropathy. CRP = C-reactive protein level ≥ 10 mg/L.Quinn MA, et al. Arthritis Rheum. 2003;48:3039–3045.
What Trumps What?
SYNOVITIS !
2010 ACR/EULARRA Classification Criteria ≥ 6 points = RA• 1 med or large joint swelling = 0 points
• 2 – 10 med or large joints swollen = 1 point
• 1 – 3 small joints swollen = 2 points
• 4 – 10 small joints swollen = 3 points
• > 10 small joints swollen = 4 points
• - RF, - CCP = 0 points
• + RF or + CCP (low titer 2-3 x normal) = 2 points
• +RF or + CCP high titer = 3 points
• Duration of synovitis > 6 weeks = 1 point
• Abnormal CRP or ESR = 1 point A & R, Aug 2010
• Treatment Goals• Make the patient feel as normal
as possible
• Prevent bony damage/disability
• Avoid toxicity
• Cost effectiveness
• Use standardized scoring to measure RA disease activity
• Treat to Target (low disease activity)

Case 2WHEN DOES A POSITIVE ANA MEAN SOMETHING??WHEN TO AVOID CHECKING AN ANA!
Case 2: The Stiff Daycare Provider• 23-year-old nonsmoking female daycare provider• Onset of pain and stiffness and swelling in her hands and wrists
beginning February 2017. Compromised activities of daily living.• Morning stiffness that would last up to 4 hours• Primary care evaluation documented new onset
hypothyroidism. No improvement in joint symptoms with T4• Trial of prednisone with prompt but temporary benefit.
Minimal benefit with diclofenac• Mother notices puffy fingers• At the same time, patient’s develops classic white
attacks/Raynaud’s phenomenon. No other formal CTD sx.(No SOB, swallowing difficulty, Dry eyes, oral ulcers, numbness, rash)
What historical features suggest inflammatory arthritis?A. Pain and stiffness in the hands
B. Prednisone helped temporarily, diclofenac without benefit
C. Puffy, swollen fingers noted by mom
D. Raynaud’s phenomenon
E. New onset hypothyroidism
F. All of the above
Fibromyalgia • Muscle attachment pain
• Hurt all over (Large > small joints)
• All day stiffness
• No swollen joints
• Normal inflammatory markers
• Other complaints• Fatigue, cognitive problems, • Paresthesia, headache• Irritable bowel and bladder
+ANA ≠ inflammatory arthritis
Predicting Pain in OA ptsafter TKA and THA• Outcomes
• Post op opioid consumption• Pain relief @ 6mo
• 9 mg > Morphine requirements for each point higher “FM-ness”
• 20% less likely to reach 50% less pain after arthroplasty with each point higher “FM-ness”

• Restrictive lung disease
Systemic Sclerosis (SSc)Subsets of SSc are :
• Diffuse cutaneous SSc (dcSSc)
• Limited cutaneous SSc (lcSSc) CREST
• SSc sine scleroderma, in which patients have only internal organ involvement
• Environmentally-induced scleroderma
• Overlap syndromes, in which features of SSc coexist with elements of other rheumatic disorder
• 70% of Systemic Sclerosis can be serologically defined.
• Serologic markers can separate Diffuse systemic sclerosis (+Scl-70) from limited /CREST(+Centromere)
• + RNA pol III puffy fingers, contracture, high risk of scleroderma renal crisis, 1st 5 years heightened risk of interstitial lung disease, increased risk of cancer

Scleroderma Mortality

Systemic Sclerosis Treatment• Arthritis and puffy fingers
/scleroderma• Methotrexate, Hydroxychloroquine,
Mycophenolate, gabapentin, pregabalin
• Avoid prednisone > 5 mg/day
• Interstitial lung disease• Corticosteroids (short term)• Mycophenolate, Cyclophosphamide• Autologous bone marrow transplant
• Renal• ACE inhibitors, …
• Raynaud's• nifedipine, amlodipine,
(dihydropyridines),phosphodiesterase-5 inhibitors, topical nitrate, fluoxetine, Botox, sympathectomy, endothelin receptor antagonists, prostacyclin, clopidogrel
• Pulmonary Hypertension• Anticoagulation, endothelin receptor
antagonists, phosphodiesterase-5 inhibitors, prostacyclin (IV and oral)
• Esophageal dysmotility, esophagitis and stricture, bacterial overgrowth • (symptomatic , antibiotics-Rifaximin)
Case 2• Hydroxychloroquine
• Mycophenolate
• Prednisone 5 mg
• Pregabalin
• Omeprazole
• IUD (not BCPs)
• PFTs stabilized after 9 mo
• BPs normal
• 14 swollen joints• 30 min AM stiff, Pain score 7
• No pulmonary HTN as of now
Summary• Does the patient have Inflammatory Arthritis?
Is there synovitis on examination?
• Does the patient have a CTD / Lupus?Is there synovitis?Is there something else? Rash, renal disease, serositis, Raynaud's, Severe dry eyes, cytopenia's
