Answer
It could be acute glomerulonephritis, commonly known as acute nephritis. Broadly speaking, it refers to a group of kidney diseases with different causes and pathogenesis, but with clinical manifestations of acute onset, characterized by hematuria, proteinuria, edema, hypertension, and decreased glomerular filtration rate. Therefore, it is also often referred to as the acute nephritis syndrome. Clinically, the vast majority belong to post-streptococcal glomerulonephritis. This condition is one of the most common kidney diseases in children. It is most common in children aged 3 to 8 years old and is rare below 2 years of age. The male-to-female ratio is approximately 2:1.
Diagnosis
Typical acute nephritis is not difficult to diagnose. After a streptococcal infection, there is a symptom-free interval of 1 to 3 weeks, followed by the appearance of edema, hypertension, hematuria (which may be accompanied by varying degrees of proteinuria), and the dynamic change of blood complement C3 can be used for an accurate diagnosis.
