Paediatric Nephrology

Pediatric Nephrology is a medical specialty focused on the diagnosis and management of kidney-related conditions in children. It involves treating both acute and chronic kidney diseases, as well as genetic and metabolic disorders that affect the kidneys in children.

Common Conditions Treated in Pediatric Nephrology:

1. Congenital Kidney Diseases:
   • Polycystic Kidney Disease (PKD): A genetic condition characterized by the growth of cysts in the kidneys.
   • Hypoplasia/Dysplasia: Underdevelopment or abnormal development of the kidneys.
   • Congenital Anomalies of the Kidney and Urinary Tract (CAKUT): Structural abnormalities that can affect the kidneys, bladder, and urinary tract.
2. Nephrotic Syndrome:
   • A kidney disorder causing excessive protein loss in urine, low levels of protein in the blood, and swelling. It often leads to fluid retention and can be idiopathic or secondary to other diseases.
3. Glomerulonephritis:
   • Inflammation of the glomeruli (filters in the kidneys) due to infections (e.g., post-streptococcal glomerulonephritis), autoimmune diseases (e.g., lupus nephritis), or other systemic conditions.
4. Acute Kidney Injury (AKI):
   • Sudden loss of kidney function, which may be caused by infection, dehydration, medication toxicity, or other conditions that damage the kidneys.
5. Chronic Kidney Disease (CKD):
   • A progressive decline in kidney function that can be caused by inherited conditions, glomerulonephritis, or nephrotic syndrome. Children with CKD may eventually require dialysis or kidney transplantation.
6. Hypertension:
   • High blood pressure can be a result of kidney disease or may contribute to further kidney damage. Managing hypertension in children is crucial to prevent complications.
7. Electrolyte and Acid-Base Imbalances:
   • Abnormalities in levels of sodium, potassium, calcium, phosphate, and acid-base balance can indicate underlying kidney dysfunction.
8. Urinary Tract Infections (UTIs):
   • Recurrent or severe UTIs in children can sometimes lead to kidney damage, especially if the infection causes a condition called pyelonephritis.
9. Kidney Stones:
   • Although less common in children than adults, kidney stones can develop and may cause pain, obstruction, or kidney damage.
10. Genetic Conditions:
    • Conditions such as Alport Syndrome (a genetic disorder affecting kidney function, hearing, and vision) and Fabry Disease (a metabolic disorder affecting kidney, heart, and skin) can lead to kidney failure in childhood.

Diagnosis:

Diagnosis in pediatric nephrology often requires a combination of:

• Clinical Examination: Assessing symptoms such as swelling, blood in the urine (hematuria), changes in urine output, and blood pressure.
• Laboratory Tests: Blood tests (e.g., serum creatinine, BUN), urine tests (e.g., urinalysis, protein/creatinine ratio), and specific markers to assess kidney function and injury.
• Imaging: Ultrasound, CT scans, and sometimes MRI are used to assess kidney size, structure, and detect any abnormalities.
• Biopsy: In some cases, a kidney biopsy is needed to identify the underlying cause of kidney dysfunction, especially in cases of glomerulonephritis.

Treatment Approaches:

1. Medications:
   • Diuretics: Used to reduce swelling in conditions like nephrotic syndrome.
   • Immunosuppressants: For autoimmune-related kidney conditions, such as glomerulonephritis.
   • Angiotensin-converting enzyme (ACE) inhibitors or Angiotensin II receptor blockers (ARBs): Often used to manage proteinuria and protect kidney function in diseases like nephrotic syndrome and chronic kidney disease.
   • Antibiotics: For treating infections like UTIs or kidney infections.
2. Dietary Management:
   • Fluid restriction: In cases of fluid retention.
   • Low-protein, low-sodium diet: Especially for children with chronic kidney disease or nephrotic syndrome.
   • Calcium and vitamin D supplementation: Often needed in children with kidney disease to maintain bone health.
3. Dialysis:
   • Hemodialysis: In cases of acute or chronic kidney failure, where the kidneys cannot filter waste products and fluids from the blood.
   • Peritoneal Dialysis: An alternative to hemodialysis, using the lining of the abdominal cavity to filter waste.
4. Kidney Transplantation:
   • For children with end-stage kidney disease (ESKD), a kidney transplant may be necessary. Pediatric nephrologists are often involved in the management of children awaiting a transplant, as well as post-transplant care.

Challenges in Pediatric Nephrology:

• Growth and Development: Kidney diseases in children can affect their growth and development, making it crucial to provide holistic care.
• Psychosocial Aspects: Chronic illness, including the need for dialysis or a transplant, can have significant psychological impacts on children and their families.
• Medication Side Effects: Children may be more sensitive to the side effects of medications used to treat kidney diseases.
• Long-Term Monitoring: Kidney diseases in children may require lifelong monitoring, especially if they require dialysis or a transplant.

Conclusion:

Pediatric nephrology is a specialized field that requires a thorough understanding of the unique aspects of kidney disease in children. Early diagnosis and treatment are crucial in preventing long-term complications, including kidney failure. Advances in medical care, including better medications, dialysis options, and kidney transplantation, have improved the outcomes for many children with kidney disease.
