The mean platelet volume (MPV) in patients with systemic lupus erythematosus (SLE) and its correlation with disease activity: a cross-sectional/case-control study.

Introduction: Systemic lupus erythematosus (SLE) is a systemic disease, with unknown etiology. The authors aimed in this study to determine the connection between mean platelet volume (MPV) and disease activity of SLE. Although it has been studied in other rheumatological conditions like rheumatoid arthritis, its role in adult patients with SLE needs to be defined, especially in Syria.
