high risk for ESRD, immunosuppressive treatment, membranous nephropathy, ACTH
Brief summary
The purpose of this study is to determine whether treatment with long-acting synthetic adrenocorticotropic hormone is in the treatment of patients with idiopathic membranous nephropathy and high for renal failure.
Interventions
Intramuscular injections with tetracosactide hexacetaat (Synacthen Depot) 1ml a 1mg/ml. Treatment for 9 months with an increasing dosage from once per 2 weeks to twice a week.
