Title: Systemic Lupus Erythematosus – Clinical Poster II: Biomarkers and Outcomes

Session Type: ACR Poster Session B

Session Time: 9:00AM-11:00AM

Background/Purpose:

Prolactin has a role in pathogenesis of Systemic Lupus Erythematous (SLE); high levels have been associated with activity. In contrast, a decrease in dehydroepiandrosterone sulfate (DHEAS) has been observed with low disease activity.

Objective: To evaluate serum PRL levels and DHEAS levels in patients with active SLE of recent onset vs patients with inactive chronic and healthy controls and their correlation with activity and chronicity scores.

Methods: serum PRL levels and DHEAS levels were studied, as well as their correlation with SLEDAI and SLICC scores. Group 1: 15 patients with SLE of recent onset (active SLEDAI >3) Group 2: 20 patients with inactive chronic SLE (SLEDAI<3) and Group 3: 20 healthy controls. SLEDAI and SLICC were calculated in group 1 and group 2 respectively. PRL and DHEAS was measurement by radioimmunoassay in all groups. Statistical analysis: U-Mann Whitney and Spearman correlation.

Results: group 1: serum PRL levels were 27.82±9.96 ng/dl vs group 2: 20±5.02 ng/dl (p= 0.004) and group 3:19.58±4.57 ng/dl (p=0.004). Group 1: serum DHEAS levels were 14.58±9.26 µg/dl, group 2: 19.36±7.21 µg/dl (p=0.04) and group 3: 154.43±50.88 µg/dl (p =0.001). The average DHEAS was lower in patients with chronic SLE vs controls (p = 0.001). A positive linear correlation was found between serum PRL levels and SLEDAI score (Rho 0.92, p=0.001). No correlation was found between PRL and SLICC score. A negative linear correlation was shown between DHEAS concentration and SLICC score (Rho-0.46, p =0.03).

Conclusion: PRL levels were higher in active SLE patients VS. chronic inactive SLE and healthy controls. In contrast, serum DHAS levels were lower in patients with active SLE vs. inactive chronic SLE. We found a positive correlation between SLEDAI score and PRL serum concentrations and an inverse correlation between SLICC score and DHAS serum levels.
