[Contraception and pregnancy in systemic lupus erythematosus].

In 1990 conflicting views are still being held concerning oral contraception and risks associated with pregnancy in women with systemic lupus erythematosus. As regards oral contraceptives, all authors agree that oestrogen-progestin combination pills are harmful, but the best alternative hormonal contraception remains to be determined. Protein-based "micropills" seem to be harmless; cyproterone acetate appears to be without side-effects, and its usefulness in preventing recurrences is being evaluated. As regards pregnancy, it would be wise not to contemplate having a child until 6 months have elapsed since the onset of remission. Blood pressure, platelet count and serum creatinine and uric acid levels must be closely monitored. Two types of antibodies may be present in the mother and are known to be responsible for foetal complications. These are antibodies to phospholipids (antiprothrombinase, anticardiolipin, antibodies responsible for dissociated treponema serology), which expose to spontaneous abortion or intrauterine death, and the antibody to SS-A (or anti-Ro), which exposes to foetal cardiomyopathy and congenital atrioventricular block.
