Introduction. Ureaplasma un Mycoplasma infections are common around the world. Associations were detected between Mycoplasma and Ureaplasma inflammatory arthritis, these bacteria can cause reactive arthritis. However, there are few studies about this problem and further research is required.
Aim. Investigate the association of Ureaplasma and Mycoplasma infection with different types of arthritis.
Materials and methods. Clinical data were collected from medical history, included demographic data, diagnosis, results of Ureaplasma and Mycoplasma urinary culture tests, HLA-B27 positivity.
Results. 1377 patients (68% female and 32% male) with arthritis were examinated. 64.8% of patients were under 50 years old and 35.2% - over 50. Ureaplasma culture was positive in 21.6%, Mycoplasma culture - in 17.9% patients. In patients with seronegative spondyloarthropathies Ureaplasma were positive in 24.4%, Mycoplasma – 19.8%. In patients with rheumatoid arthritis - 15.3%, and 16%, osteoarthritis 5.2%, 5.2% and crystal arthropathies 8.9%, 4.4% accordingly. In patients with reactive arthritis Ureaplasma was positive in 26.1% and Mycoplasma in 20.8%, in ankylosing spondylitis - Ureaplasma in 16% and Mycoplasma in 14.5% of patients, in psoriatic arthritis - 14.7% and
14.7% accordingly.
Conclusions. Ureaplasma and Mycoplasma infections have association with inflammatory arthropathies. These bacterial infections are most common in patients with seronegative spondyloarthropathies, especially in patients with reactive oligoarthritis. In patients with osteoarthritis and crystal arthropathies Ureaplasma and Mycoplasma infections are rare.
