Abstract

BACKGROUND:

Systemic lupus erythematosus (SLE) affects women of child-bearing age. Combined oral contraceptives can worsen the course and increase the risk of thrombosis. The objectives of this study were to provide an alternative contraception and thus evaluate the gynecological tolerability of pregnane progestins (PPs) in SLE patients. Systemic lupus erythematosus disease activity and vascular tolerance were also reported.

STUDY DESIGN:

We used two PP with antigonadotropic potencies, chlormadinone acetate (CMA, 10 mg/day) and cyproterone acetate (CPA, 50 mg/day), administered orally for contraception in 187 SLE patients observed for 46±34.6 months (mean±S.E.), i.e., 6854 women-months.

RESULTS:

The gynecological tolerability was satisfactory: breakthrough bleeding was reported in 17.7% patients using CPA and 12.6% patients using CMA. No pregnancy was observed in the women followed in this cohort study. One deep vein thrombosis, one myocardial infarction, and one tibial posterior arterial occlusion were observed, giving an incidence for venous thromboembolism of 1.39/year×1000 women (95% CI 0-4.12) and for macroarterial disease an incidence of 2.79/year×1000 women (95% CI 0-6.65). Disease activity was less than before progestins.

CONCLUSIONS:

Pregnane progestin contraception is effective and well tolerated, thus providing SLE patients an excellent contraceptive alternative to the currently used methods.
