Furthermore, there is also evidence that CRP evaluation could be used to evaluate chronic inflammation in vasculitis and rheumatoid arthritis, and that CRP levels slightly higher than normal represent a useful marker for cardiovascular diseases-related inflammation, thus making this protein a very versatile tool in clinical practice, even if its low specificity does not support conclusive diagnoses in the absence of other clinical evidence [81,82,83,85,86]. This evidence concerns the gene CRP and rheumatoid arthritis.
