Although the joints are almost always the principal focus of the rheumatoid arthritis, other organ systems may also be involved. Extra-articular manifestations of rheumatoid arthritis occur most often in seropositive patients with more severe joint disease. Interestingly, extra-articular manifestations can occur in later stages of the disease when there is little active synovitis ("burnt-out" disease). In contrast to the predilection of rheumatoid arthritis for women, extra-articular manifestations of the disease are more common in men
![Page 38: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/38.jpg)
Cardiopulmonary Disease There are several pulmonary manifestations of rheumatoid arthritis, including pleurisy with or without effusion, intrapulmonary nodules, rheumatoid pneumoconiosis (Caplan's syndrome), diffuse interstitial fibrosis, and rarely, bronchiolitis obliterans pneumothorax. On pulmonary function testing, there commonly is a restrictive ventilatory defect with reduced lung volumes and a decreased diffusing capacity for carbon monoxide. Although mostly asymptomatic, of greatest concern is distinguishing these manifestations from infection and tumor. Pericarditis is the most common cardiac manifestation
![Page 39: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/39.jpg)
Ocular Disease Keratoconjunctivitis of Sjogren's syndrome is the most common ocular manifestation of rheumatoid arthritis. Sicca (dry eyes) is a common complaint. Episcleritis occurs occasionally and is manifested by mild pain and intense redness of the affected eye. Scleritis and corneal ulcerations are rare but more serious problems.
![Page 40: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/40.jpg)
Neurologic Disease The most common neurologic manifestation of rheumatoid arthritis is a mild, primarily sensory peripheral neuropathy, usually more marked in the lower extremities. Entrapment neuropathies (e.g., carpal tunnel syndrome and tarsal tunnel syndrome) sometimes occur in patients with rheumatoid arthritis because of compression of a peripheral nerve by inflamed edematous tissue. Cervical myelopathy secondary to atlantoaxial subluxation is an uncommon but particularly worrisome complication potentially causing permanent, even fatal neurologic damage.(top of section)
![Page 41: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/41.jpg)
Sjogren's Syndrome Approximately 10 to 15% of patients with rheumatoid arthritis, mostly women develop Sjogren's syndrome, a chronic inflammatory disorder characterized by lymphocytic infiltration of lacrimal and salivary glands. This leads to impaired secretion of saliva and tears and results in the sicca complex: dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca). Patients with Sjogren's syndrome have a variable expression of disease in other exocrine glands. This is manifested clinically as dry skin, decreased perspiration, dry vaginal membranes, or a nonproductive cough. Commonly, there is also a polyclonal lymphoproliferative reaction characterized by lymphadenopathy and splenomegaly. This can mimic and rarely transform into a malignant lymphoma

Rheumatoid Nodules
The subcutaneous nodule is the most characteristic extra-articular lesion of the disease. Nodules occur in 20 to 30% of cases, almost exclusively in seropositive patients. They are located most commonly on the extensor surfaces of the arms and elbows but are also prone to develop at pressure points on the feet and knees. Rarely, nodules may arise in visceral organs, such as the lungs, the heart, or the sclera of the eye. (learn more about rheumatoid nodules in case report #6)(top of section)

Rheumatoid Vasculitis The most common clinical manifestations of vasculitis are small digital infarcts along the nailbeds. The abrupt onset of an ischemic mononeuropathy (mononeuritis multiplex) or progressive scleritis is typical of rheumatoid vasculitis. The syndrome ordinarily emerges after years of seropositive, persistently active rheumatoid arthritis; however, vasculitis may occur when joints are inactive.

The course of rheumatoid arthritis cannot be predicted in a given patient. Several patterns of activity have been described:
•a spontaneous remission particularly in the seronegative patient within the first •6 months of symptoms (less than 10%) •recurrent explosive attacks followed by periods of quiescence most commonly •in the early phases •the usual pattern of persistent and progressive disease activity that waxes and •wanes in intensity.
Disability is higher among patients with rheumatoid arthritis with 60% being unable to work 10 years after the onset of their disease. Recent studies have demonstrated an increased mortality in rheumatoid patients. Median life expectancy was shortened an average of 7 years for men and 3 years for women compared to control populations. In more than 5000 patients with rheumatoid arthritis from four centers, the mortality rate was two times greater than in the control population. Patients at higher risk for shortened survival are those with systemic extra-articular involvement, low functional capacity, low socioeconomic status, low education, and prednisone use.

Analgesic Drugs Pain caused by inflammation is best treated with an anti-inflammatory drug, although occasionally the addition of acetaminophen can be helpful. Chronic narcotic therapy is not used routinely due to side effects such as diminished mental status, hyper somnolence, constipation, and dependency. Furthermore, they have no anti-inflammatory activity. They may be needed for patients with severe joint destruction who are not surgical candidates.

PE
Pathophysiology: AS most commonly affects the SI joints and the axial skeleton. Involvement of the SI joints is required to establish the diagnosis. Hip and shoulder joints are affected less frequently. Peripheral joint involvement is least common.
The initial presentation generally occurs in the SI joints and is followed by involvement of the discovertebral, apophyseal, costovertebral, and costotransverse joints and the paravertebral ligaments
![Page 78: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/78.jpg)
Chronic involvement of the spine eventually can lead to decreases in ROM and fusion of the vertebral bodies. Involvement of the cervical and upper thoracic spine can lead to fusion of the neck in a stooped forward-flexed position (see Images 1-2). This position can significantly limit the patient's ability to ambulate and look straight ahead.
![Page 79: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/79.jpg)
Focus the physical examination on active ROM and passive ROM of the axial and peripheral joints. Tenderness in the SI joints is common.
•Screen for extra-articular manifestations by performing specific examinations (eg, ophthalmologic, cardiac, and gastrointestinal examinations).

Gout
Most common form of acute arthritis in elderly
Occurs secondary to crystal deposition in the joint
May be acute or chronic and may have extra articular manifestations
![Page 113: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/113.jpg)
The peak incidence of acute gout occurs between 30 and 50 years of age Approximately 90 percent of first attacks are monoarticular. In more than one half of patients with acute gout, the first metatarsophalangeal joint is the initial joint involved, a condition known as podagra. Joint involvement (in order of decreasing frequency) includes the metatarsophalangeal joint, the instep/forefoot, the ankle, the knee, the wrist and the fingers.
![Page 114: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/114.jpg)
Gout in women occurs exclusively after menopause. Women develop gout at an older age than men and have twice the prevalence of hypertension, renal insufficiency and exposure to diuretics. The onset of gout before age 30 in men or before menopause in women is atypical and raises concern about an associated inherited enzyme defect or renal disease.

Acute Gout The four treatment options available for the acute gouty attack are NSAIDs, colchicine, corticosteroids and analgesics
![Page 120: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/120.jpg)
NSAIDs are the preferred therapy for the treatment of patients without complications. Indomethacin (Indocin) was the first NSAID used for gout, but other NSAIDs, including ibuprofen (Motrin), naproxen (Naprosyn), sulindac (Clinoril), piroxicam (Feldene) and ketoprofen (Orudis) are also effective in the treatment of acute gout. Maximum dosages should be given immediately after the onset of symptoms or at the time of diagnosis and continued for 24 hours after complete resolution of the acute attack, then tapered quickly over two to three days.
![Page 121: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/121.jpg)
Colchicine, an antimitotic drug derived from the roots of the herb Colchicum autumnale, is one of the oldest treatments for gout. Although colchicine is effective in treating acute gout, 80 percent of patients experience gastrointestinal side effects, including nausea, vomiting and diarrhea, at therapeutic dosages. Furthermore, colchicine is less effective once an acute attack has persisted for a few days.
![Page 122: ortho chronic.ppt](https://reader033.vdocuments.site/reader033/viewer/2022061105/5443f578b1af9f740a8b4717/html5/thumbnails/122.jpg)
Corticosteroids, administered intra-articularly, intravenously, intramuscularly or orally, have been shown to be effective in the treatment of acute gout.
