The Role of Power Doppler Ultrasonography as Disease Activity Marker in Rheumatoid Arthritis

الملخص EN

Structural damage in rheumatoid arthritis (RA) occurs early if inflammation is not treated promptly.

Treatment targeted to reduce inflammation, in particular, that of synovial inflammation in the joints (synovitis), has been recommended as standard treat-to-target recommendations by rheumatologists.

The goal is to achieve disease remission (i.e., no disease activity).

Several accepted remission criteria have not always equated to the complete absence of true inflammation.

Over the last decade, musculoskeletal ultrasonography has been demonstrated to detect subclinical synovitis not appreciated by routine clinical or laboratory assessments, with the Power Doppler modality allowing clinicians to more readily appreciate true inflammation.

Thus, targeting therapy to Power Doppler activity may provide superior outcomes compared with treating to clinical targets alone, making it an attractive marker of disease activity in RA.

However, more validation on its true benefits such as its benefits to patients in regard to patient related outcomes and issues with standardized training in acquisition and interpretation of power Doppler findings are required.
