Rheumatoid arthritis and other autoimmune diseases might be triggered
by infectious agents, We have reviewed the evidence suggesting that my
coplasmas may play a role in the genesis of arthritis, Mycoplasmas are
a common cause of spontaneous arthritis in many animal species, Numer
ous experimental models of mycoplasma-induced arthritis have been deve
loped, some with mycoplasmas known to cause disease in humans, Mycopla
smas entertain complex relationships with the immune system of their h
osts and frequently induce autoimmune events such as rheumatoid factor
production, However, the potential role of mycoplasmas in human joint
disease remains unknown, Mycoplasmas can be responsible for septic ar
thritis in patients with immune deficiencies, especially hypogammaglob
ulinemia. Whether mycoplasmas can incite or perpetuate inflammatory jo
int diseases such as rheumatoid arthritis remains controversial, Advan
ces in molecular biology techniques for detecting infectious agents ca
n be expected to settle this issue in the near future.
