Patient's question:
My cousin's daughter, who was just born this year, has recently shown symptoms such as a small nose, low nasal bridge, wide eye distance, and poor muscle tone. After being examined at the pediatric department of People's Hospital, she was diagnosed with congenital nephrotic syndrome. I would like to ask, what exactly is congenital nephrotic syndrome?Doctor's answer:
Congenital nephrotic syndrome is a kidney disease that typically manifests shortly after birth, around 3 to 6 months of age. It exhibits the four major characteristics of nephrotic syndrome: ① massive proteinuria, with a qualitative test result of ≥( ) and a quantitative daily level exceeding 0.1 g/kg; ② hypoproteinemia, with serum albumin < 3 g/L; ③ hypercholesterolemia, with serum cholesterol exceeding 5.72 mmol/L; ④ edema.
