Informations about the disease

Clinical Comment

Steroid-resistant nephrotic syndrome (SRNS) is defined as nephrotic syndrome (NS) that is unresponsive to steroid therapy. The majority of children presenting with idiopathic NS have minimal disease that is responsive to steroid therapy. However, 10-20% of patients do not respond to initial steroid treatment. One-third of steroid-resistant cases are due to single gene mutations that affect glomerular podocyte structure and/or function. Patients with genetic forms of SRNS usually do not respond to immunosuppressive therapy, the disease progresses rapidly, and the risk of disease relapse is low. Therefore, therapeutic decisions in children with SRNS are based on the underlying etiology. 50% of patients with SRNS will progress to end-stage renal disease. The DNA diagnostic yield is 30% in SRNS. A negative molecular genetic result does not constitute exclusion of the clinical diagnosis.
