Abstract Because of the high rate of spontaneous remission, treatment of membranous nephropathy with prednisolone and chlorambucil is still controversial. The aim of this study was to give this therapy only to those patients at risk of developing renal insufficiency and to test the efficacy of a low-dose therapeutic regimen. Seventeen patients with more than 10 g protein excretion per day (mean 16.9) and/or a deterioration in renal function (mean serum creatinine, 162 μmol/l) were included. Serum total protein, serum lipids, proteinuria, serum creatinine, and blood pressure were measured, along with the diuretic and antihypertensive medication. The observation time before the start of treatment was 27 ± 27 months. Steroids were given during months 1, 3, and 5 (methylprednisolone 3 × 500 mg intravenously) prednisolone 0.5 mg/kgBW daily per os for 1 week, then tapered by 0.1 mg/kg BW/week for 1 month. Chlorambucil was given during months 2, 4, and 6 at a dose of 0.12 mg/kgBW daily. At the end of treatment proteinuria had significantly decreased (mean of all patients, 7.8 ± 1.4 g/d) in all patients. Six months after the end of treatment proteinuria was significantly lower than at baseline in 14 of 17 patients. Hypoproteinemia and hyperlipidemia had improved; diuretic and antihypertensive medication were reduced. Elevated serum creatinine decreased in 7 of 9 patients (pretreatment, 227 ± 39 μmol/1; 6 months, 176 ± 28 μmol/l). Nonresponders with respect to serum creatinine responded with respect to proteinuria. Regarding adverse effects, two patients complained of dyspepsia while taking steroids; during chlorambucil treatment two patients experienced nausea and lack of appetite, and one developed leukopenia (1600/μl). Chlorambucil was stopped and cell counts normalized 2 weeks later. We conclude that low-dose prednisolone/chlorambucil is both safe and efficient in the majority of patients with severe membranous nephropathy.
