ABZYME ACTIVITY OF POLYCLONAL IMMUNOGLOBULINS IN SPONDYLOARTHROPATHIES
Abstract. Polyclonal immunoglobulins G (subclasses 1, 2, 4) from sera of 255 patients and 69 healthy persons were studied by a combined approach using rivanol treatment and affinity chromatography. Enzymatic reactions were carried out according to the methods that we have previously developed and va...

| Sumario: | Abstract. Polyclonal immunoglobulins G (subclasses 1, 2, 4) from sera of 255 patients and 69 healthy persons were studied by a combined approach using rivanol treatment and affinity chromatography. Enzymatic reactions were carried out according to the methods that we have previously developed and validated for evaluation of abzyme activity in the patients with different disorders. The levels of DNase, proteolytic BAPNA-amidase (benzoylarginine-p-nitroanilide amidase), and superoxyde dismutase abzyme activity in spondyloarthropathies proved to be significantly higher (p = 0.001), as compared with a control group. Catalase activity of immunoglobulines in the disorders studied was compatible to control levels (p > 0.05). Analysis of relations between abzyme activity and clinical and laboratory signs of the diseases has revealed some significant correlations. Prevalence of abzyme DNAse activity is found in the patients with psoriatic arthritis, as compared to reactive arthritis and ankylosing spondilitis (p < 0.001). |
