Lithium-induced nephrotic syndrome in a young pediatric patient

Lithium-induced nephrotic syndrome is a rare complication of lithium therapy and is even rarer in children. Most reported cases have been secondary to minimal change disease, which reverses within 1–4 weeks on discontinuation of lithium therapy. However, focal glomerulosclerosis (FSGS) has occasionally been reported and is not always reversible with discontinuation of lithium. We report an 11-year-old child with lithium-induced FSGS nephrotic syndrome who went into full remission after lithium was discontinued.
