Abstract
OBJECTIVE: To evaluate whether a short duration treatment with cyclophosphamide (CYC) followed by mycophenolate mofetil (MMF) is associated with preservation of the ovarian function in female patients with systemic lupus erythematosus (SLE). METHODS: We retrospectively evaluated 61 premenopausal women with SLE treated for lupus nephritis (n=58), autoimmune hemolytic anemia (n=1) and central nervous system involvement (n=2). Thirty-nine patients received prolonged treatment with 1 g/m2 intravenous (IV) CYC pulses (group I). 22 patients received 5-7 monthly 1 g/m2 IV CYC pulses and afterwards 2 g/day MMF (group II). RESULTS: Disease activity was equally controlled using either regimen (p=0.76 and p=0.31 for disease remission and relapse respectively). Amenorrhea developed in 56% of women in group I (n=22) and 14% in group II (n=3) (p=0.01), whereas sustained amenorrhea developed in 51% (n=20) of women in group I versus 4% (n=1) in group II (p=0.05). Most women with amenorrhea in group I (86%) did not resume menses after the cessation of therapy versus one woman (33%) in group II. In logistic regression, group I had a 4-fold higher risk of amenorrhea and 5-fold higher risk of sustained amenorrhea compared to group II (p=0.001 and p=0.009 respectively). Age (p<0.001), cumulative CYC dose (p=0.001) and anti-Ro antibodies (p=0.002) were significant in terms of amenorrhea, while sustained amenorrhea was significantly associated with the patient age (p=0.026). CONCLUSION: We suggest that treatment with MMF following 5-7 IV pulses of CYC is an effective mean to control disease activity and preserve ovarian function in premenopausal women with SLE.
