Study of serum adenosine deaminase activity and c-reactive protein in patients of rheumatoid arthritis

Abstract

Rheumatoid arthritis (RA) is a chronic disease that causes inflammatory synovitis. The treatment plan of RA includes reducing inflammation and improving the quality of life. Hence, understanding the role of Adenosine deaminase (ADA) and C-reactive protein helps for a better plan of treatment. The present study was undertaken to determine the serum ADA activity and CRP in RA patients and correlate with the severity of the progression of the disease. 25 patients diagnosed with RA as per 2010 ACR/EULAR criteria and 25 age and sex matched healthy controls were included in the study after informed consent. Blood samples were collected from all the subjects after an overnight fast, serum separated was analyzed immediately for Adenosine deaminase(ADA) activity measured using colorimetric method of Guisti and Galanti. Disease score, C-reactive protein, RA factor, ADA and ESR were significantly higher in cases when compared with controls. Significant positive correlation was present between the disease score and C-reactive protein, RA factor among cases. A positive correlation was observed between the disease score and ADA, but it was not statistically significant among cases.
