[Treatment of glomerulonephritis]. / Therapie der Glomerulonephritis.

The treatment of primary glomerulonephritis is a complex matter because of an unclear clinical picture. Glomerulonephritis may emerge as acute nephritis, nephrotic syndrome or minor proteinuria or hematuria. The symptomatic treatment may be derived from the clinical status; immunosuppressive therapy has to be substantiated by renal biopsy in order to offer the best choice to the patient.Rapid-progressive glomerulonephritis must be treated aggressively, as early as possible, to prevent chronic renal failure. Nephrotic syndrome should be treated symptomatically. Immunosuppressants are indicated according to the histological picture and accompanying clinical risk factors for progressive renal disease, which have to be evaluated before treatment. This paper gives the current strategies for treating primary glomerulonephritis.
