Sir—Guillermo Ruiz-lrastorza and colleaguesl do not mention that a striking feature of SLE is the predominance of young women who develop the disease in their childbearing years. Lupus has a tendency to flare during pregnancy and the puerperium, but the huge increase in incidence of SLE over the past four decades (from 1· 51 per 100000 in 1950–79 to 124· 0 per 100 000 in 1995) suggests that contraceptive pills and hormonereplacement therapy are the main causes. Hughes2 notes a sex ratio of nine women to one man for the much more common antiphospholipid syndrome, which affects 10% of pill thrombosis cases.In the Nurses’ Health Study, 3 the risk for developing SLE increased with duration of use of postmenopausal hormones and was 2· 5 for current users. In the Royal College of General Practitioners’ oral contraceptive study, 4 many disorders associated with SLE were increased in the first 3 years. These included most of the neuropsychiatric manifestations listed by Ruiz-lrastorza and colleagues. The ratios of standardised rates for takers compared with controls were increased between two and five times for dermatological manifestations, erythema nodosum, and Raynaud’s syndrome; and vascular and neuropsychiatric manifestations, including deep venous thrombosis of the leg, headache and migraine, epilepsy, and depression.
