Cyclosporine for lupus membranous nephritis:experience with ten patients and review of the literatureDepartment of Rheumatology, Ceders-Sinai Medical Center/UCLA School of Medicine, 8700 Beverly Boulevard, Suite 2003, Los Angeles, CA 90048, USA;David Hallegua, 8737 Beverly Boulevard, Suite 203, Los Angeles, CA 90048, USA
Department of Rheumatology, Ceders-Sinai Medical Center/UCLA School of Medicine, 8700 Beverly Boulevard, Suite 2003, Los Angeles, CA 90048, USA Objectives: The treatment of lupus membranous nephritis (LMN), a lupus subset that carries a high morbidity, is unsatisfactory. We report our experience in treating LMN with the immunosuppressive drug cyclosporine (CYS). Methods: We treated 10 patients with systemic lupus erythematosus fulfilling ACR criteria with CYS for at least 12 months and followed renal function, serologic activity and SLEDAI scores. Patient characteristics:8 females, 2 males, 50% Caucasian, mean age 37.3 y (range 2248), disease duration 108.7 months (range 16216), nephritis duration 35.5 months (range 1259), date of biopsy to date of starting treatment 10.7 months (range 090). The patients were started on CYS with a mean dose of 3.8 mg/kg (range 2.26) and followed for a mean duration of 24.8 months (range 1259). A Medline search identified all patients with lupus who were given CYS or had LMN in articles from 19661999. Results: Proteinuria improved from a baseline mean of 5588 mg/24 h (range 271211 055) to 1404 mg/24 h (range < 1502652). Serum albumin increased from a baseline mean of 2.8 g=100 ml (range 1.313.8) to a mean of 3.9 g/100 ml (range 34.5) at last follow-up. There was no significant change in lupus activity as measured by SLEDAI. Nephrotoxicity was common as evidenced by an increase in serum creatinine but it returned to baseline with adjustment of the dose of CYS (20% decrease in the dose of CYS for a 20% increase in serum creatinine). More antihypertensive medications were required to control the blood pressure in these ten patients at the end of the study compared to the onset (total number = 13 versus 6). Conclusion: Proteinuria and serum albumin improved in all patients on CYS. A literature review is consistent with this. Controlled studies of the use of CYS for membranous lupus nephritis would be useful.
