Glomerulonephritis itself does not appear as a low-grade fever, if glomerulonephritis patients appear as a low-grade fever should be considered with other diseases, the following specific analysis. The actual nephritis is a disease involving autoimmunity, a sterile inflammation, the pathogenesis of which is the reaction of antigenic antibodies to form immune complexes that settle in the kidneys and produce inflammation. Glomerulonephritis symptoms mainly include swelling of both lower extremities, poor nasal function, weakness, elevated blood pressure and other manifestations, urine routine shows positive urine protein, positive occult blood, decreased blood albumin, etc. Therefore, patients with glomerulonephritis itself will not have a low fever that does not go away. If a patient with glomerulonephritis has a low fever that does not subside, it should be considered to be accompanied by other diseases such as upper respiratory tract infections, immune system diseases such as lupus erythematosus, etc. Further examination is needed to clarify the diagnosis. If a patient with nephritis is accompanied by bacterial infections such as bronchitis, anti-inflammatory treatment should be given and penicillin or cephalosporin antibiotics can be used for treatment.
