How common is nephrotic syndrome
What is the incidence and prevalence of nephrotic syndrome and has it changed in recent years?
The incidence of nephrotic syndrome is approximately 2 to 4 new cases per 100,000 population per year.
There are data suggesting that the incidence of nephrotic syndrome is rising in certain populations around the world, such as Indians and Southeast Asians.
However, the overall figure has been fairly steady and is applicable around the world and in most racial and ethnic groups.
There may be a difference in the incidence of specific types of primary nephrotic disease in children and adults.
The prevalence of nephrotic syndrome as a cause of chronic kidney disease varies from country to country depending on the practice patterns for disease detection and treatment.
Nonetheless, primary nephrotic syndrome is an uncommon illness and qualifies for designation as a rare disease.
