RESUMO
The aim of this prospective study was to determine clinical factors associated with adverse pregnancy outcomes in women with systematic lupus erythematosus (SLE). Fifty-six pregnancies from 46 women with SLE were enrolled. Risk factors for pregnancy loss, premature delivery, hypertensive disorders of pregnancy (HDP), and light-for-date neonate (LFD), were evaluated. Univariate and multivariate logistic regression analyses revealed a history of two or more pregnancy losses before 10 gestational weeks (GW) (OR 11.5, 95%CI 1.72-76.8) as a risk factor for pregnancy loss; low levels of blood complements (OR 7.55, 95%CI 1.10-51.9) and antiphospholipid syndrome (OR 26.5, 95%CI 3.17-219) as risk factors for premature delivery before 37 GW; SLEDAI score at conception (OR 1.68, 95%CI 1.05-2.68) and positive tests for two or more antiphospholipid antibodies (OR 6.89, 95%CI 1.13-41.9) as risk factors for premature delivery before 34 GW; prednisolone therapy >14mg/day (OR 7.55, 95%CI 1.10-51.9) as a risk factor for HDP; and low dose aspirin therapy (OR 0.21, 95%CI 0.05-0.97) decreased the risk for LFD neonate. These results have important implications for clinicians managing SLE complicated pregnancy.
