Mommy Vlog #1 - My Sick Child Nephrotic Syndrome Minimal Change Disease
Minimal Change Disease
Minimal-change disease, sometimes called nil disease, affects the millions of the kidney’s glomeruli, which are the specific parts of the kidney where small molecules are first filtered out of blood and into the urine.
Specifically, it’s a type of nephrotic syndrome, in fact, the most common nephrotic syndrome seen in children.
But what exactly is nephrotic syndrome? Well usually the glomerulus only lets small molecules—like sodium and water—move from the blood into the kidney nephron where it eventually make its way into the urine.
But with nephrotic syndromes, the glomeruli are damaged and they become more permeable, so they start letting plasma proteins come across from the blood to the nephron and then into the urine, which causes proteinuria—typically greater than 3.5 grams per day.
An important protein in the blood is albumin, and so when it starts leaving the blood, people get hypoalbuminemia—low albumin in the blood.
With less protein in the blood the oncotic pressure falls, which lowers the overall osmotic pressure, which drives water out of the blood vessels and into the tissues, called edema.
Finally, it’s thought that as a result of either losing albumin or losing some protein or proteins that inhibit the synthesis of lipids—or fat—you get increased levels of lipids in the blood, called hyperlipidemia.
Just like the proteins, these lipids can also get into the urine, causing lipiduria.
And those are the hallmarks of nephrotic syndrome—proteinuria, hypoalbuminemia, edema, hyperlipidemia, and lipiduria.
Okay, so minimal change disease is a type of nephrotic syndrome—got it, but how exactly do those glomeruli start letting plasma proteins like albumin through?
