Acute nephritis is actually a sterile inflammation, with significant proliferation of cells within the glomeruli, primarily related to immune dysfunction. Therefore, from this perspective, acute nephritis does not show symptoms of fever. However, due to the inflammatory response within the glomeruli causing acute nephritis, patients may experience renal failure. In the state of renal failure, the patient's immune capability further decreases, which could lead to complications from infections, with respiratory infections being the most common, including pneumonia, bronchitis, and acute tonsillitis. These inflammations may cause fever, but this fever is not a direct result of the acute nephritis itself.
