AIM: Cardiovascular disease (CVD) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). The aim of this study was to evaluate subclinical atherosclerosis and to determine the prevalence of risk factors for CVD in SLE patients.
METHODS: One hundred fifty-three patients (149 women and 4 men), aged (37±11.6) years with a definite diagnosis of SLE according to the revised criteria of the American College of Rheumatology (ACR), underwent physical examination, carotid and leg arteries B-mode ultrasound with a measure of ankle-brachial pressure index (ABPI); 94 patients had myocardial tomoscintigraphy. The laboratory check-up was: total cholesterol (TC), HDLc, LDLc, homocystein, glycemia, vascular cell adhesion molecules (VCAM-I). All patients had a normal renal function at the time of the study.
RESULTS: The mean age is 37 years. Cardiovascular events were noticed in 15 patients (6 angina, 2 myocardial infarction and 7 strokes). Cardiovascular risk factors (CVRF) were: dyslipidemia (62.8%), moderate homocysteinemia (55%), BMI>25 (39%) and hypertension (35%) which is associated with a stroke (P<0.0006). The cumulative prednisone dose per patient was 45.5g. V.C.A.M-I level was high in 86.2 % of cases.95% of our patients had at least two CVRF. Myocardial perfusion stress scanning showed abnormalities in 21 patients (22.3%). Perfusion defects were linked with a stroke (P<0.01) and coronary events (P<0.02). Carotid atheroma was present in 32 patients (20.9%). Carotid plaques were associated with age (P<0.01), total cholesterol (TC)(P<0.05), and steroid dose (P<0.01). Intima-media-thickness was correlated with age (P<0.0003), TC (P<0.0007), LDLc (P<0.002), and homocysteine (P<0.03). 70% patients had a mediacalcinosis in femoral and popliteal arteries. The ABPI was correlated with V.C.A.M-I (P<0.0005).
CONCLUSION: In Algeria, as elsewhere, young women with SLE have subclinical atherosclerosis which must be detected and they are at high risk of a vascular event.
