Do novel inflammation biomarkers arising from routine complete blood count play a role in patients with systemic lupus erythematosus?

Background: Laboratory-based biomarkers accurately presenting systemic lupus erythematosus (SLE) disease activity may have a practical value in clinical routine. As shown in many other conditions, complete blood count (CBC)-derived biomarkers may also play a role in SLE.

Objectives: We aimed to study for the first time the pan-immune-inflammation value (PIV, monocytes x platelets x neutrophils/lymphocytes) and the more established systemic immune-inflammation index (SII, neutrophils x platelets /lymphocytes) in SLE patients and correlate it with serological and clinical findings including disease outcomes.
