Familial steroid-sensitive idiopathic nephrotic syndrome: seven cases from three families in China
The fourth case was a 15-year-old boy (the brother of the third patient) who had four relapses at 17, 18, 20, and 22 years of age. After the fourth relapse, the patient underwent a renal biopsy, which identified MCD. After two weeks of prednisone therapy, the proteinuria disappeared, and the patient has maintained normal renal function for the past 3.6 years.
