  • Title: Immunosuppression can arrest progressive renal failure due to idiopathic membranous glomerulonephritis.
    Author: Williams PS, Bone JM.
    Journal: Nephrol Dial Transplant; 1989; 4(3):181-6. PubMed ID: 2498775.
    Abstract:
    The effect of pulse intravenous methylprednisolone therapy followed by oral immunosuppression was evaluated in ten patients with idiopathic membranous glomerulonephritis who had developed progressive renal failure--a group generally considered to have a poor prognosis. The patients (six male, four female, mean age 50 years) were monitored over 9-30 months during which time creatinine clearance reduced from (mean +/- SEM) 83 +/- 10 to 29 +/- 6 ml/min, and plasma creatinine increased from 135 +/- 22 to 297 +/- 35 mumol/l. All patient were nephrotic with mean 24-h urinary protein excretion ranging from 5.8 to 19.6 g. Treatment administered was pulse intravenous methyl-prednisolone 1 g X 3 then oral prednisolone 30 mg and azathioprine 50 mg (nine patients) or cyclophosphamide 50 mg (one patient). Mean prednisolone dosage was 25 mg at 3 months, 16 mg at 6, and 10 mg at 12 months. Patients have been followed up for between 12 and 57 months on therapy. Creatinine clearance increased to 39 +/- 6, 47 +/- 5 and 48 +/- 18 ml/min after 3, 6 and 12 months treatment with a fall in proteinuria to 6.2 +/- 1.7, 5.7 +/- 1.4, and 3.1 +/- 1.1 g/24h. The deterioration of renal function was reversed in six patients (associated with a reduction in proteinuria to less than 1 g/24 hours in five), slowed in three (with a significant reduction in proteinuria in two), and only one patient with more advanced renal failure before treatment progressed to end-stage failure without any retardation of the rate of deterioration or change in proteinuria.(ABSTRACT TRUNCATED AT 250 WORDS)
