A potential biomarker of disease activity in systemic lupus erythematosus, systemic immune-inflammation index.

Objective: Biomarkers using routine laboratory tests accurately presenting systemic lupus erythematosus (SLE) disease activity may have important practical values in clinical settings. The primary purpose of this study was to investigate neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII; neutrophil X platelet/lymphocyte) as potential biomarkers of disease activity in cases with SLE.

Methods: In this case-control observational study, cases with SLE and demographically similar healthy controls were included.

Does fibromyalgia affect physical activity due to pain?

Objectives: The aim of this case-control study was to evaluate the physical activity levels of patients with fibromyalgia syndrome (FMS) and to assess a possible relation between physical activity and FMS characteristics.

Methods: Seventy patients with FMS and 50 age-gender-matched controls were included. Pain was evaluated using the visual analog scale.
