As suggested by the name, nephrotic syndrome is a syndrome. A syndrome is a condition in a patient who suffers from multiple vivid disorders which occur simultaneously. Usually, the reason for these disorders occurring simultaneously is that they are associated with each other by an underlying dysfunction. In nephrotic syndrome, there are four main disorders that are manifested due to some dysfunction at the level of nephrons in the kidneys. In this blog, we aim to understand these four disorders, their cause, symptoms, diagnosis, and treatment.
The nephrotic syndrome appears as a tetrad of disorders. This tetrad is consisted of:
To know the cause of this tetrad we must look at its pathophysiology. As already said, this tetrad is a result of some dysfunction at the level of nephrons; we will first look at the basic anatomy of nephrons to understand the pathophysiology of nephrotic syndrome effectively.
A nephron is the functional unit of the kidney. An afferent arteriole comes into the head of the nephron to give an input of blood. This afferent arteriole makes the glomerulus within the head of the nephrons by twisting itself. The output of blood after being filtered in nephrons is the efferent arteriole coming out of it. This efferent arteriole joins the other efferent arteriole to form the renal vein. The renal vein eventually enters the circulation.
In nephrotic syndrome, an inflammation in the glomerulus causes it to be damaged. This inflammation can be the result of the action of antibodies, complement proteins, immune complexes, hypertension, or sclerosis. Whatever the cause, the inflammation and damage in the glomerulus are specifically caused in podocytes. Podocytes are the cells that prevent protein loss. This damage in podocytes acts as an initiative for the tetrad to occur resulting in nephrotic syndrome. To understand this, we will discuss the progressive cause of each of the disorders of nephrotic syndrome:
Diagnosis of nephrotic syndrome is done to; confirm the presence of the condition, assess the severity and differentiate different types of nephrotic syndrome based on its causes. This diagnosis can be done by:
As nephrotic syndrome can have numerous causes, it is important to consider the relevancy of a treatment option for a specific patient. But regardless of the cause, there are certain general protocols to be made operational for a patient suffering from nephrotic syndrome. These protocols are as follows:
In this blog, we have viewed certain important measures associated with nephrotic syndrome. No matter how specific we try to be in medical content like this, it is important to promote the idea of personal advice given to a patient by his/her doctor. The importance of a checkup from an expert can never be overstated.
