The objective of the submitted study was to evaluate the role of the serum level of the soluble form of the vascular adhesive molecule-1(VCAM-1) in systemic lupus erythematosus (SLE) and to evaluate the possible relation to selected clinical and laboratory indicators of activity of the disease and cytokine serum levels. The analyzed group comprised 20 women, median age 37 years (range 18-65 years). Elevated VACM-1 serum levels were detected in 18 subjects (90%). Statistical analysis (Pearson's test, p < 0.05) revealed a significant relationship between serum levels of VCAM-1 and the index of clinical activity of SLE evaluated by the ECLAM system (European Consensus Lupus Activity Measurement), values of the C3 complement component, the level of antibodies against dsDNA and serum levels of IL-10. No significant correlation was found with levels of the soluble receptor IL-2 (sIL-2R) and the C4 complement component in serum. From the investigation ensues that investigation of serum levels of the adhesive molecule of the VCAM-1 type is a promising method which makes early diagnosis of exacerbation of the disease possible. However, for evaluation of its real asset in clinical practice a more widely conceived longitudinal investigation is needed.
