[Fibronectin and its clinical significance in patients with osteoarthrosis, psoriatic arthropathy and chronic prostatis with a joint syndrome].

The differential diagnostic importance of plasma fibronectin in rheumatology is still undecided. Its role as opsonin is being discussed at present. The fibronectin plasma level is discussed in relation to the severity of the disease, characterized by morphologic and quantitative radionuclide indices, in 30 patients with osteoarthrosis, 10 patients with psoriatic arthropathy, 32 patients with chronic urethroprostatitis and joint syndrome and in 34 healthy controls. The results for plasma fibronectin (controls--382.0 +/- 91.0, osteoarthrosis I stage--266.0 +/- 40.1, osteoarthrosis II stage--400.6 +/- 38.7, osteoarthrosis III stage--550.7 +/- 48.2, psoriatic arthropathy I stage--322.6 +/- 35.3, psoriatic arthropathy II stage--443.3 +/- 41.4, psoriatic arthropathy III stage--471.5 +/- 36.7, chronic bacterial prostatitis--287.6 +/- 86.0, non-bacterial prostatitis--360.0 +/- 83.8, chronic trichomonas prostatitis--447.6 +/- 67.0 g/ml) are reliable supplement which characterized the destructive--reparative joint reaction and the features of the joint syndrome in chronic urethroprostatitis which takes place in opsonin deficit.
