Can Mean Platelet Volume Be a Surrogate Marker of Inflammation in Rheumatic Diseases?

Area of Science:

• Rheumatology
• Hematology
• Inflammation Biomarkers

Background:

• Low mean platelet volume (MPV) is potentially linked to secondary thrombosis due to inflammation.
• MPV is considered a potential marker for systemic inflammation.

Purpose of the Study:

• To investigate the association between MPV and inflammatory markers (ESR, CRP) and disease activity scores (DAS-28, BASDAI).
• To evaluate MPV as a potential biomarker in various rheumatic diseases.

Main Methods:

• The study included 261 rheumatoid arthritis, 85 ankylosing spondylitis, 56 familial Mediterranean fever, and 194 patients with other rheumatic diseases.
• Correlations between MPV, ESR, CRP, DAS-28, and BASDAI were analyzed.

Main Results:

• A significant inverse correlation was observed between MPV and ESR/CRP in rheumatoid arthritis, ankylosing spondylitis, familial Mediterranean fever, psoriatic arthritis, systemic lupus erythematosus, and other rheumatic diseases.
• MPV showed negative correlations with DAS-28 in rheumatoid arthritis and BASDAI in ankylosing spondylitis.

Conclusions:

• Lower MPV levels are indicative of active or chronic inflammatory states in rheumatic diseases.
• MPV may function as a negative acute-phase reactant for assessing rheumatic disease activity.
