title: Nail-patella syndrome, infantile nephrotic syndrome: complete remission with antiproteinuric treatment.
abstract: A girl, second child of healthy parents, was referred to the Renal Unit at the age of 9 months with haematuria (230 RBC/microl) and proteinuria (2.4 g/l). Serum creatinine was normal (0.25 mg/dl), albumin low (34 g/l) and cholesterol elevated (223 mg/dl). Physical examination showed bilateral webbing of the elbows, equinovarus of both feet and absent patellae. The clinical diagnosis of nail-patella syndrome was confirmed by demonstrating a splice mutation in the intron 5 (750 + 1 G>A) of the LMX1B gene. Treatment with enalapril for 2 years (0.1-1 mg/kg per day) did not bring about any change in urinary protein excretion. However, enalapril (1 mg/kg per day) associated with losartan (1 mg/kg per day) resulted in complete remission (proteinuria 140 mg/24 h) at the age of 7 years.
