[Management of patients with nephrotic syndrome]

Nephrotic syndrome is a group of clinical symptoms and laboratory findings, caused by heavy proteinuria, which may be caused by many glomerular diseases. In the approach to a patient with nephrotic syndrome is important to establish an aetiology of the disease, with excluding its secondary causes and in most cases with renal biopsy. The treatment aims to prevent or slow further kidney damage. It involves addressing the underlying medical condition and the treatment of symptoms such as edema, proteinuria, hyperlipidemia, as well as preventing complications like thromboembolic disease, infections or undernutrition.
