| Abstract |
| The aim of this study was to evaluate the incidence
of morphologic and functional cardiac abnormalities in patients with
systemic lupus erythematosus (SLE) and to correlate the findings
with levels of anti-Ro/SS-A, anti-La/SS-B, and anti-cardiolipin antibody
(aCL). Sixty-two patients with SLE were enrolled in this study. All
patients underwent complete history taking, clinical assessment,
and standard two-dimensional and Doppler echocardiography. Anti-Ro/SS-A,
anti-La/SS-B, and aCL levels were measured using a standardized ELISA
test. The patients were subdivided into two subgroups based on the
presence or absence of valvular involvement. The two subgroups were
then compared. Valvular involvement was present in 19 patients (30.6%),
pericardial effusion in 12 patients (19.4%), impaired left ventricular
relaxation abnormalities in 2 patients (3.2%), and pulmonary hypertension
in 3 patients (4.8%). More patients in the valvular involvement group
had positive anti-Ro/SS-A antibodies than in the valvular noninvolvement
group (7/19 vs. 4/43). The difference was significant, with P 0.01.
Serum levels of anti-Ro/SS-A levels were significantly higher in
the valvular involvement group (33.7 ± 36.0 vs. 13.7 ± 25.1; P 0.01),
as were the serum anti-La/SS-B levels (21.9 ± 23.5 vs. 10.7 ± 17.8;
P 0.05). The results suggest a causative correlation between anti-Ro/SS-A
and anti-La/SS-B antibodies and the pathogenesis of the valvular
lesions in SLE patients. |
