Pregnancy outcomes before and after a diagnosis of systemic lupus erythematosus.
OBJECTIVE
The purpose of this study was to evaluate pregnancy outcomes before and after diagnosis of lupus.


METHODS
Successive selection criterion applied to 148 lupus and 78,905 non-lupus pregnancies, generated 3 groups: lupus group, 84 pregnancies (not-yet-diagnosed group, 15 women; already-diagnosed group, 69 women), and control group, 51,000 pregnancies. Three-way analysis of variance and the chi-squared test were used for analyses.


RESULTS
Stillbirth outcome was increased in the lupus group compared with the control group (odds ratio, 4.84 [95% CI, 1.72,11.08]); the not-yet-diagnosed group (odds ratio, 9.89 [95% CI, 1.09,42.63]), and the already-diagnosed group (odds ratio, 3.85 [95% CI, 1.02,10.31]). Considering >1 pregnancy per patient would have overestimated the stillbirth rate. Stillbirth risk was increased significantly in severe maternal disease that was marked by central nervous system involvement. The already-diagnosed group had more hypertensive complications (P = .001 and .0001). Both lupus groups showed a significantly greater proportion of preterm births (P = .03), growth restriction (P = .019), and infants in the very low birth weight category (P = .021) compared with the control group.


CONCLUSIONS
Poor fetal outcomes are seen in pregnancies that are complicated by lupus, even before clinical appearance of disease, which supports a predisease state.
