Acute nephritis is commonly seen in pediatric patients. One to three weeks before the onset of acute nephritis, infections often occur in the throat, upper respiratory tract, and skin. Once acute nephritis occurs, the typical clinical manifestations of the patient are hematuria, which can be gross hematuria or microscopic hematuria. There is also edema, especially noticeable swelling of the eyelids and face after getting up in the morning. Due to the edema and reduced urine output, the patient often experiences a significant increase in blood pressure. Of course, in addition to these clinical manifestations, the patient may also experience irritability, back pain, nausea, loss of appetite, and poor spirit. Patients with acute nephritis can also experience severe complications, such as hypertensive encephalopathy, acute heart failure, acute renal failure, etc. Therefore, acute nephritis must be given sufficient attention and actively treated.
