Metabolic profiling of synovial tissue shows altered glucose and choline metabolism in rheumatoid arthritis samples.

The article focuses on a study which showed the use of metabolic profiling of synovial tissue in accurately diagnosing rheumatoid arthritis RA). Topics discussed include the altered glucose and choline metabolism in the synovial tissue of RA samples, the relative quantification of metabolites for evaluating the metabolic differences between the tested groups, and the similarity of the observed metabolic pattern in the synovial fluid (SF) of RA and osteoarthritis patients.
