Arthritis patients at risk
Arthritis is common to those patients having musculoskeletal disorders. It is
not a disease condition rather a disease manifestation.
Rheumatoid
Arthritis
The etiology of rheumatoid arthritis is unknown. Investigation as to causation
is being explored primarily in relation to autoimmune, infectious, hereditary,
environmental, and psychosomatic factors.
-
Autoimmune Factors- Impressive evidence supports the importance of an
immunologic mechanism in the pathogenesis of rheumatoid arthritis. Evidence
to support this theory was the discovery of the rheumatoid factor (RF) in
the serum of patients with rheumatoid arthritis. This factor has an affinity
for denatured gamma globulin probably in the patient’s synovial membrane. It
was this discovery that led to the classification of rheumatoid arthritis as
an autoimmune disease.
-
Infectious Factors- The inflammatory nature of rheumatoid arthritis implied
an infectious process. However, overwhelming negative results of
bacteriologic studies suggest that rheumatoid arthritis is probably not due
to a bacterium. The focus is on viruses because there are several viral
infections that produce transient arthritis even though no virus has been
found in the synovium.
-
Hereditary Factors – It was noted by clinician that rheumatoid arthritis
seemed to occur most often within the same families, raising the question of
heredity as a contributing factor. Several studies of twins support the
possibility that rheumatoid arthritis occurs twice as often in people who
are blood relatives and therefore are genetically predispose to this
disease. Theses statistics suggest a hereditary influence, but no clear-cut
genetic pattern has been identified.
-
Environmental Factors – Other researchers favor an environmentally based
theory because of the following findings: (1) The onset for a large number
of people has occurred in the spring of the year, and (2) many people have
increased symptomatology when the humidity increases and the barometric
pressure decreases.
-
Psychosomatic Factors- The literature abounds with research relating to the
personalities and psychological mechanisms of patients with rheumatoid
arthritis. There is little support for the theory that certain “personality
types” relate to the cause of this disease, but the course of rheumatoid
arthritis appears to be influenced by emotional factors.
Bacterial Arthritis
Factors that predispose to such infections are a high degree of susceptibility
on the part of the patient, recent joint surgery or trauma, intraarticular
injections, and rheumatoid arthritis.
Osteoarthritis
Women are more severely affected by the disease, although the incidence rates
are the same for males and females. Primary joint disease is the most common
type of noninflammatory joint disease. The etiology is unknown, but age is an
important factor in the development of the disease. The quantity and quality of
proteoglycans decrease with the aging process and predispose the cartilage to
break down and degenerate. Research indicates there may be a genetic component
to the development of osteoarthritis.
Gouty Arthritis
(gout)
Gout is more common to men than women. Ninety- five percent of the cases of gout
occur in men between the ages 20 and 60. There is also a hereditary
predisposition for gout. Many have heard the old wives’ tale that much
indulgence in rich foods and alcohol will precipitate an attack of gout. In
fact, the patient should be instructed to avoid foods with high purine content,
like liver, kidneys, sweetbreads, anchovies, and meat gravies.
