Abstract:
Background: Women with rheumatoid arthritis (RA) and systemic lupus erythematosus
(SLE) are at high risk of cardiovascular diseases (CVD). The atherogenic index of plasma (AIP) is
a new marker for the assessment of CVD.
Objective: This study aimed to determine the predictive value of AIP with long-term CVD risk
among women with RA and SLE.
Methods: This is a cross-sectional study of 99 RA and 59 SLE women. Demographic, clinical, and
biochemical data were obtained, and disease activities were calculated. For each patient, the longterm
risk of CVD was calculated using the Framingham risk score (FRS); AIP was derived according
to the logarithmic (triglycerides/high-density lipoproteins cholesterol).
Results: The mean age of the RA and SLE patients was 47.97 ± 8.78 and 36.75 ± 9.09 years, respectively.
The median (interquartile range) of AIP values in RA and SLE patients were 0.34
(-0.15, 1.02) and 0.33 (-0.53, 0.96), respectively, while FRS values of RA patients and SLE patients
were 6.38 ± 5.58 and 4.86 ± 4.5, respectively (p >0.05). There was a moderate correlation between
AIP and FRS in RA and SLE patients (r=0.42, p=0.002 and r=0.33, p=0.007, respectively).
According to the multivariate regression analyses, we found that AIP value is an independent factor
for FRS in RA (β: 4.13, 95% confidence interval; 1.71, 6.18; p=0.008) and in SLE patients (β:
6.19, 95% confidence interval; 2.58, 9.81; p<0.001).
Conclusions: We reported that AIP can be used as an independent indicator for long-term CVD
risk in RA and SLE patients.
