The patients were examined twice: at visit 1 - to correct treatment, and at visit 2 - after 3 months after correction of treatment. Measurements included clinical status, spirometry, plasma level of HA.The control group consisted of 13 healthy individuals (age - 53,2±2,8 yrs).Results: we found that on visit 1 the level of HA in main group was significantly higher than in patients of the control group (0,21±0,01 ng/ml comparing to 0,15±0,01 ng/ml) (p<0,05). At visit 2 HA level decreased significantly in all patients comparing to this one on visit 1, it’s average rate was 0,16 ng/ml (p<0,05), which corresponded to the level of the control group.Conclusion: the significant decreasing of HA level in COPD patients may be a marker of the effectiveness of anti-inflammatory therapy.
