জ্যানথিনিউরিয়া

Overview 

Xanthinuria is a rare genetic condition in which the body cannot properly break down purines due to a deficiency of the enzyme xanthine oxidase. This leads to the accumulation of xanthine in the body and reduced levels of uric acid.

Excess xanthine can form kidney stones, which may cause pain and urinary problems. Early diagnosis and dietary management are important to prevent complications.

Types of Xanthinuria Disease

• Type I Xanthinuria: Deficiency of xanthine oxidase enzyme
• Type II Xanthinuria: Deficiency of both xanthine oxidase and aldehyde oxidase
• Secondary Xanthinuria: Caused by certain medications or conditions

Symptoms of Xanthinuria

• Kidney stones (often first symptom)
• Flank or abdominal pain
• Blood in urine (hematuria)
• Difficulty urinating
• Recurrent urinary tract issues
• Muscle pain (in rare cases)

Causes of Xanthinuria

• Genetic mutation affecting purine metabolism
• Deficiency of xanthine oxidase enzyme
• Autosomal recessive inheritance
• Rarely caused by medications

Complications of Xanthinuria

• Recurrent kidney stones
• Urinary tract obstruction
• Kidney damage (in severe cases)
• Chronic pain
• Reduced kidney function

Risk Factors of Xanthinuria

• Family history of the condition
• Genetic inheritance
• Consanguinity in some populations

Prevention of Xanthinuria

• Genetic counseling
• Maintaining a low-purine diet
• Adequate hydration
• Regular monitoring for kidney stones
