Hyaluronic acid solution positively correlated with SLE activity (P = 0.025). (P = 0.028) and CRP (P = 0.009). However, HA was not found to correlate with the duration of rheumatic diseases. Conclusions Hyaluronic acid concentration undergoes changes in rheumatic diseases with no difference between RA, SLE and SSc. In RA, HA concentration can be […]
