Which of the following is characterized by inflammation of the glomerulus?

Glomerular Nephritis is a condition specifically characterized by inflammation of the glomeruli, which are the tiny filtering units within the kidneys. This inflammation can result from a variety of causes, including infections, autoimmune responses, or other underlying health conditions.

In Glomerular Nephritis, the inflammation can lead to symptoms such as hematuria (blood in urine), proteinuria (excess protein in urine), and reduced kidney function. The glomeruli play a crucial role in filtering waste and excess substances from the blood, so their inflammation can impair kidney function and lead to more severe kidney damage if left untreated.

While other options may involve kidney complications, none of them specifically denote inflammation of the glomerulus. Diabetic Nephropathy involves damage to the kidneys resulting from diabetes but does not focus solely on glomerular inflammation. Cystic Nephrosis and Polycystic Kidney Disease are characterized by the presence of cysts in the kidneys rather than inflammation of the glomeruli.
