Congenital Nephrotic Syndrome in Children

Overview

Congenital nephrotic syndrome (CNS) is a rare kidney disorder that affects infants and young children. Unlike other forms of nephrotic syndrome, which can develop later in life, CNS is present at birth or shortly after. This condition is characterized by excessive protein loss in the urine, leading to a range of symptoms and potential complications. CNS can be caused by genetic mutations and requires specialized care to manage effectively.

Symptoms

Children with congenital nephrotic syndrome may exhibit the following symptoms:

  • Excessive protein in the urine (proteinuria): This is the primary symptom and can lead to other complications.
  • Swelling (edema): Fluid accumulation in various parts of the body, such as the face, abdomen, and legs.
  • Low protein levels in the blood (hypoalbuminemia): This can cause weakness and fatigue.
  • High cholesterol levels (hyperlipidemia): Elevated cholesterol levels in the blood.
  • Frequent infections: Due to a weakened immune system.
  • Poor growth and development: Children may struggle to gain weight or grow at a normal rate.

Causes

Congenital nephrotic syndrome is typically caused by:

  • Genetic mutations: Most cases of CNS are inherited and linked to mutations in genes that affect the kidneys’ ability to filter proteins properly.
  • Infections: In some cases, infections during pregnancy can lead to CNS.
  • Other underlying conditions: Rarely, CNS can be associated with other medical conditions affecting the kidneys.

Diagnosis

To diagnose congenital nephrotic syndrome, our pediatric nephrologists will perform a series of tests, including:

  • Physical examination and medical history: The doctor will assess symptoms and review any family history of kidney problems.
  • Urinalysis: To check for excessive protein in the urine.
  • Blood tests: To measure protein levels, cholesterol levels, and kidney function.
  • Genetic testing: To identify specific gene mutations if inherited CNS is suspected.
  • Kidney biopsy: In some cases, a small sample of kidney tissue may be taken to confirm the diagnosis.

Treatment Options

While there is no cure for congenital nephrotic syndrome, the condition can be managed through various treatments aimed at reducing symptoms and preventing complications. Treatment options include:

  • Medications:
    • Diuretics: To help reduce swelling by increasing urine output.
    • Immunosuppressants: To suppress the immune system and reduce inflammation.
    • Antibiotics: To treat and prevent infections.
  • Dietary modifications: A low-salt diet can help reduce swelling, and a high-protein diet can help maintain adequate protein levels in the blood.
  • Regular monitoring: Frequent follow-up visits with the nephrology team are necessary to monitor kidney function and adjust treatment as needed.
  • Kidney transplant: In severe cases, a kidney transplant may be recommended to restore normal kidney function.
