Study Description: SLE patients with life-threatening lupus manifestations are often treated with cyclophosphamide (CYC), which has known cytotoxic effects on ovarian reserve. Co-administration of Gonadotropinreleasing hormone agonist (GnRHa) is suggested to protect ovaries from the cytotoxic effects of CYC but there is lack of data to support this. We hypothesize that the co-administration of a GnRH agonist for the duration of CYC therapy will exert protective effects on ovarian reserve and function in SLE females. We plan to do a patient survey and a retrospective data collection to compare ovarian function in subjects who received CYC with GnRHa to those who received CYC without GnRHa.
Objectives:
Primary Objective: Determine the effectiveness of GnRH-a in preventing primary ovarian insufficiency (POI) in female SLE patients getting cyclophosphamide treatment.
Secondary Objectives: Determine the effects of SLE disease activity, damage accrual, cumulative dose of cyclophosphamide and other demographic and clinical variables in preventing primary ovarian insufficiency.
