May I congratulate the authors of the commentary describing contraceptive options for women with systemic lupus erythematosis (SLE).1 This was a comprehensive summary and I was interested in their views regarding the suitability of progestogen-only methods in women with antiphospholipid antibodies. The authors felt these methods were unsafe in such women (World Health Organization Medical Eligibility Criteria for Contraceptive Use Category 3 – generally risks outweigh the benefits of use). As up to 42% of women with SLE will be positive for these antibodies2 the authors are reducing contraceptive choice to barrier methods, copper intrauterine devices or sterilisation.

About one-third of women with antiphospholipid antibodies develop a venous thromboembolism (VTE) in their lifetime and this risk is further increased in pregnancy and the puerperium.2 Maternal mortality in women suffering from SLE is thought to be 2–3%.3 We now have good evidence that progestogen-only contraceptive methods such as the levonorgestrel-releasing intrauterine system and desogestrel pill do not increase the risk of VTE in the general population.4 A recent study also suggested that oral pregnane progestogen contraceptives appear to have little effect on the development of VTE in women with SLE (where 29.4% of 187 women had detectable antiphospholipid antibodies).5

Perhaps the authors would like to provide an additional comment?
