Anti-apolipoprotein A-I antibodies and paraoxonase 1 activity in Systemic Lupus Erythematosus.

Ahmed MM, Elserougy EM, Al-Gazzar II, Fikry IM, Habib DF, Younes KM, Salem NA - EXCLI J (2013)

Bottom Line: Compared with controls, SLE patients showed significantly lower PON1 activity and significantly higher titers of anti-Apo A-I.Elevated titers of anti-Apo A-I antibody and reduced PON activity were related to increased SLEDAI and (SLICC/ACR) damage index scores.We concluded that there is decreased PON1 activity and formation of anti-Apo A-I antibodies in female patients with SLE.

ABSTRACT
Systemic lupus erythematosus (SLE) patients have an increased risk of atherosclerosis. Identification of at-risk patients and the pathogenesis of atherosclerosis in SLE remain elusive. Paraoxonase 1 (PON1) and anti-apolipoprotein A-I antibody (anti-Apo A-I) appear to have a potential role in premature atherosclerosis in SLE. The aim of this work was to study PON1 activity and anti-Apo A-I antibody in SLE female patients and to demonstrate their relations to disease activity as well as disease related damage. Forty SLE female patients and 40 apparently healthy volunteers were included. Anti-Apo A-I antibodies levels and PON1 activity levels were assessed. Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and systemic Lupus International Collaboration Clinics (SLICC)/American College of Rheumatology (ACR) damage index were preformed in all patients. Compared with controls, SLE patients showed significantly lower PON1 activity and significantly higher titers of anti-Apo A-I. Anti-Apo A-I antibody titers correlated inversely with PON1 activity. Elevated titers of anti-Apo A-I antibody and reduced PON activity were related to increased SLEDAI and (SLICC/ACR) damage index scores. We concluded that there is decreased PON1 activity and formation of anti-Apo A-I antibodies in female patients with SLE. SLE-disease activity assessed by SLEDAI and SLE disease related organ damage assessed by SLICC/ACR damage index are negatively correlated with PON1 activity and positively correlated with anti-Apo A-I antibodies. PON1 activity and anti-Apo A-I antibodies might be involved in the pathogenesis of atherosclerosis in SLE patients.

T9: Apolipoprotein A-I antibody levels in the presence and the absence of different disease manifestations

Mentions: Statistically significant differences were present between PON1 activity levels in the presence and absence of constitutional and CNS manifestations. Otherwise, no significant differences were present between PON1 activity levels in the presence and absence of other disease manifestations (Table 8(Tab. 8)). Statistically non-significant differences were present between the Anti-Apo A-I levels in the presence or absence of all the studied disease manifestations (Table 9(Tab. 9)).
