Bromocriptine (BRC) prevents postpartum flare in lupus patients. However, its potential role in protecting lupus pregnancy from maternal-fetal complications has not been studied. The objective of the study was to explore the role of oral BRC during pregnancy in patients with systemic lupus erythematosus (SLE). Pregnant SLE patients were randomized into two groups: group 1 received BRC 2.5 mg/day and prednisone 10 mg/day; group 2 received prednisone 10 mg/day. These treatments were administered from 25 to 35 weeks of gestation. Prolactin (PRL) levels were determined at 25, 30, and 35 weeks. The SLE Pregnancy Disease Activity Index, maternal-fetal outcome including preterm birth, fetal loss, premature rupture of membrane (PRM), low birth weight, and preeclampsia/eclampsia were evaluated. We studied 20 patients (10 in each group). A significant decrease of PRL levels in group 1 compared to group 2 at week 30 and at week 35 was found. No patients in the BRC group had flares and three from group 2 had SLE activity. None of the patients in group 1 had PRM but three patients in group 2 did. Eighty percent of pregnancies ended in birth at term in group 1 and 50% in group 2. There was no fetal loss in both groups. Mean birth weight was higher in group 1 than in group 2 (P < NS). BRC was well tolerated. This is the first clinical trial of BRC in SLE pregnancy. Our pilot study suggests that BRC may play a role in the prevention of maternal-fetal complications, such as PRM, preterm birth, and active disease.
