Effect of ozone therapy on neutrophil/lymphocyte, platelet/lymphocyte ratios, and disease activity in ankylosing...

This retrospective self-controlled randomized study was carried out with the participation of 53 patients diagnosed with ankylosing spondylitis according to the modified New York criteria. The patients who did not receive medical treatment or did not change their medical treatment within the last 6 months were included in the study. There was a statistically significant decrease in the patients' neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, monocyte/lymphocyte ratio, C-reactive protein, Visual Analog Scale, Bath Ankylosing Spondylitis Functional Index, and Bath Ankylosing Spondylitis Disease Activity Index scores measured after ozone therapy. There was a positive correlation between neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, mean platelet volume/lymphocyte ratio, monocyte/lymphocyte ratio and C-reactive protein, Visual Analog Scale, Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Disease Activity Index before and after ozone therapy. Our study revealed that the changes in the decreasing tendency of the markers measured in complete blood count after ozone therapy were correlated with the disease activity, which can contribute to understand the effect of ozone therapy on biomarkers.
