Is a chronic, systemic, inflammatory disorder of unknown etiology that primarily involves joints
◦ The most common inflammatory arthritis
◦ Arthritis is symmetrical may lead to destruction of joints due to erosion of cartilage and bone which leads to deformity
◦ Extraarticular manifestations may
be present (nodules, neuropathy, scleritis, pericarditis, splenomegaly)
◦ F>M 2:1, mean age 50-55
Rheumatoid Arthritis (RA)
Morning stiffness > 1 hour Arthritis of three or more joint groups with
soft tissue swelling Swelling involving 1 or more joint groups:
wrist, proximal IPJ, MCP, MTP Active symmetric joint swelling Hand X-ray changes typical of RA that must
include erosions or unequivocal bony decalcification
Subcutaneous nodules + Rheumatoid factor

The characteristic joint deformities appear in more established chronic RA. These findings include ulnar deviation swan neck or Boutonniere deformities of the fingers, or the “bow string” sign (prominence of the tendons in the extensor compartment of the hand)
Occasional patients present with extensor tendon rupture, most commonly affecting the thumb, little or ring fingers of either hand.
RA - Hands
DMARDS are divided into two categories: nonbiological and biological ◦ The nonbiological: methotrexate, sulfasalazine,
lefunomide (Pyrimidine synthesis inhibitor), all primary options. Hyroxychloroquine, secondary option
◦ The biological DMARDS: target specific cytokines or their receptors, such as tumor necrosis factor. Other types of biological DMARDS include B cell depleting agents and Tcell costimulatory blockers. The use of biologic DMARDS has been referred to as “targeted therapy”
◦ 1st line for mild-moderate disease at initial presentation
Possible options: ◦ Mild-moderate disease is usually started on a single
DMARD. MTX most common first line drug. Other options leflunomide (LEF), sulfasalazine (SSZ), and hydroxychloroquine (HCQ)
The addition of ONE of the following agents to MTX: ◦ tumor necrosis factor (TNF) inhibitor: adalimumab,
etanercept, or infliximab, abatacept (T cell costimulation blocker), rituximab (depletes B cells),
or anakinra (interleukin-1 receptor antagonist)

Inflammatory reaction to URATE crystals in joints, bones and subcutaneous structures
Crystals in joint fluid is pathognomonic
Hyperacute arthritis ◦ Primary: Most common, under-excretion or
overproduction of uric acid
◦ Secondary: related to myloproliferative DZ, treatments inducing hyperuricemia, renal failure/tubluar disorders, glycogen storage dz
Age 30-60, M>F 20:1
Risks: ETOH, Fam hx, MEDS (diuretics induce 20% of secondary gout), obesity/HTN (50%), diet
S/S: 7mg/dl men, >6mg/dl women)
Risk of kidney stones

Avoid foods high in purines, such as liver and other organ meats, dried peas and beans, veal, turkey, and some types of fish, including anchovies, shrimp, mackerel, and scallops.
Stop drinking large amounts of alcohol. Alcohol interferes with excretion of uric acid, and alcoholic beverages contain purines

Acute: NSAIDs (first line) for 10-14 days Treatment of gout should be initiated with an NSAIDs to
control acute inflammation. At the maximum recommended doses, NSAIDs effectively treat arthritis caused by crystals.
◦ Unlike the newer, equally effective NSAIDs, indomethacin frequently causes dyspepsia and can cause central nervous system side effects such as headache and mental status changes
Antigout Agents Colchicine (second line), may be helpful with patients who
cannot tolerate or have contraindications to NSAIDs and corticosteroids.
◦ With the availability of other agents, however, there is little role for colchicine in the treatment of acute gout, particularly in elderly patients.
Recurrent Gout: 2-3 weeks post acute episode ◦ First line: Urate lowering agent
Allopurinol, Febuxostat
