What is a classic manifestation of acute glomerulonephritis?

Acute glomerulonephritis often manifests with low-grade fever, which reflects a body's response to inflammation or infection. This condition typically arises after a streptococcal infection, where immune complexes may deposit in the glomeruli, leading to inflammation. The presence of a low-grade fever indicates that there is some sort of systemic response to this underlying pathological process.

In addition to low-grade fever, other classic signs of acute glomerulonephritis include hematuria, proteinuria, and edema. These symptoms result from the disruption of normal kidney function due to inflammation of the glomeruli.

The option of high-grade fever is less common in acute glomerulonephritis compared to low-grade fever, as it typically suggests a more acute or severe infectious process. Severe abdominal pain is not a classical manifestation of this kidney disorder; rather, it indicates an issue related to abdominal organs. Finally, excessive urination is not characteristic of acute glomerulonephritis; instead, the condition generally leads to oliguria or reduced urine output due to the kidneys’ impaired ability to filter effectively. Therefore, the identification of low-grade fever as a classic manifestation aligns well with the underlying pathophysiology of acute glomerul
