What complication can arise in a child with Berger's disease?

In the context of Berger's disease, also known as IgA nephropathy, acute renal failure is a significant complication that can arise. This condition is characterized by the deposition of IgA antibodies in the kidney's glomeruli, leading to inflammation and damage to the renal tissues over time.

As kidney function declines due to ongoing glomerular damage, children may experience acute renal failure, which presents as a sudden decline in kidney function, leading to the accumulation of waste products in the blood and electrolyte imbalances. Symptoms may include decreased urine output, swelling, and hypertension. Monitoring kidney function and early intervention are essential to manage this potential complication effectively.

The other options, while they represent serious medical conditions, are not directly related to Berger’s disease. Thus, they do not encompass the specific renal complications that can arise from the pathophysiology of IgA nephropathy.
