When a child has nephritis, it is usually acute glomerulonephritis and is usually treated with antibiotics, diuretics to reduce swelling and control blood pressure. Most cases of nephritis in small children are acute glomerulonephritis. Most of this nephritis is caused by Streptococcus haemolyticus infection, and since it is caused by infection, antibiotics need to be applied for anti-infection treatment. The antibiotics that are sensitive to this bacteria are penicillin and cephalosporins, and the more commonly used ones are penicillin sodium for injection and ceftriaxone. Many children with acute nephritis have edema, either eyelid edema or bilateral lower limb edema, and can be treated with diuretics to reduce the edema. Many children with acute nephritis have hypertension, and elevated blood pressure can be controlled with nifedipine, a drug that is safer for children. The prognosis for this type of nephritis is good, and most of them can be cured. All the above treatments are only symptomatic and need to wait for the kidneys to fully recover.
