Azithromycin suppressed relapses of idiopathic nephrotic syndrome in a child

Abstract

Long-term immunosuppressive therapy with severe adverse effects is indispensable to maintain disease remission in frequently relapsing nephrotic syndrome (NS) in children. Hence, development of new therapy with less toxicity for relapses of NS is required. We demonstrated a case of a 2-year-old boy with frequently relapsing NS, whose frequent relapses were successfully treated with azithromycin. Azithromycin treatment prevented the need for long-term immunosuppressive therapy in this case. Azithromycin could be a new treatment option for relapse of NS, with few adverse effects, in selected cases.
