Metabolic Disorder

Primary Hyperoxaluria Type 1

HIGH SEVERITY

Rare autosomal recessive disorder caused by deficiency of alanine-glyoxylate aminotransferase (AGT). Leads to overproduction of oxalate, causing recurrent kidney stones, nephrocalcinosis, and end-stage renal disease.

Symptoms

Recurrent kidney stones
Nephrocalcinosis
Hematuria
Flank pain
Renal colic
Growth retardation
Fractures
Anemia

Treatment Options

High fluid intake
Potassium citrate
Pyridoxine (vitamin B6)
Lumasiran (RNAi therapy)
Dialysis
Kidney transplantation
Combined liver-kidney transplant

Risk Factors

1Autosomal recessive inheritance
2Consanguinity
3Family history

Diagnostic Methods

  • 124-hour urine oxalate
  • 2Plasma oxalate
  • 3Kidney stone analysis
  • 4Genetic testing
  • 5Renal ultrasound
  • 6CT scan

Prognosis

Without treatment, ESRD develops in 50% by age 15, 80% by age 30. Lumasiran reduces urinary oxalate by 65%. Combined liver-kidney transplant offers best long-term outcome with 80% 10-year survival. Early diagnosis and aggressive management improve outcomes significantly. Oxalate deposition in bones and other organs occurs in ESRD.

Prevention

  • Genetic counseling
  • Prenatal diagnosis
  • Newborn screening (limited regions)
  • Early treatment

Research Status

High fluid intake and potassium citrate to reduce stone formation. Pyridoxine (vitamin B6) reduces oxalate in some patients. Lumasiran (RNAi therapy) approved to reduce oxalate. Combined liver-kidney transplant for ESRD.
