[Antibacterial drugs in the treatment of osteoarthrosis: results of a prospective randomized trial].

65 patients with knee and hip joints osteoarthrosis with concomitant urinary infection and/or irritable colon syndrome were randomized into three groups: group 1 (21 patients) received doxicyclin 200 mg/day with nistatine for three weeks with 3-week interval between the courses and bifidum-bacterin administration between the courses and after the treatment; group 2 (22 patients) received biseptol 1920 mg for 3 weeks then 960 mg 10 days a month; group 3 (22 patients) consisted of controls who received no antibacterial drugs. The effect was assessed upon randomization, 3 weeks, 3, 6 and 12 months after the treatment. It was established that antibacterial treatment not only attenuated dysuria and dyspepsia but also had a significant positive effect on osteoarthrosis especially in patients with x-ray stage II, allowed to reduce doses of nonsteroid antiinflammatory drugs. Further studies will help specify the role of the infection factor in development of osteoarthrosis and potential of antibacterial treatment.
