Learn About Focal Segmental Glomerulosclerosis
Focal segmental glomerulosclerosis is scar tissue in the filtering unit of the kidney. This structure is called the glomerulus. The glomeruli serve as filters that help the body get rid of harmful substances. Each kidney has thousands of glomeruli.
"Focal" means that some of the glomeruli become scarred. Others remain normal. "Segmental" means that only part of an individual glomerulus is damaged.
Segmental glomerulosclerosis; Focal sclerosis with hyalinosis
The cause of focal segmental glomerulosclerosis is often unknown.
The condition affects both children and adults. It occurs slightly more often in men and boys. It is also more common in African Americans. Focal segmental glomerulosclerosis causes up to a quarter of all cases of nephrotic syndrome.
Known causes include:
- Drugs such as heroin, bisphosphonates, anabolic steroids
- Infection
- Inherited genetic problems
- Obesity
- Reflux nephropathy (a condition in which urine flows backward from the bladder to the kidney)
- Sickle cell disease
- Some medicines
Symptoms may include:
- Foamy urine (from excess protein in the urine)
- Poor appetite
- Swelling, called generalized edema, from fluids held in the body
- Weight gain
Treatments may include:
- Medicines to reduce the body's inflammatory response.
- Medicines to lower blood pressure. Some of these medicines also help reduce the amount of protein that spills into the urine.
- Medicines to get rid of excess fluid (diuretic or "water pill").
- Low sodium diet to reduce swelling and lower blood pressure.
The goal of treatment is to control the symptoms of nephrotic syndrome and prevent chronic kidney disease or failure. These treatments may include:
- Antibiotics to control infections
- Fluid restriction
- Low-fat diet
- Low- or moderate-protein diet
- Vitamin D supplements
- Dialysis
- Kidney transplant

A large portion of people with focal or segmental glomerulosclerosis will develop chronic kidney disease or failure.
Complications may include:
- Chronic kidney disease or failure
- End-stage kidney disease
- Infection
- Malnutrition
- Nephrotic syndrome
Contact your provider if you develop symptoms of this condition, especially if there is:
- Fever
- Pain with urination
- Decreased urine output
No prevention is known.
Background: Focal segmental glomerulosclerosis (FSGS) is a disease that causes scarring in parts of the kidneys that filter waste. This can lead to protein loss in the urine, which can worsen kidney function. The kidneys may fail over time, and dialysis or a kidney transplant may be needed. Other treatments for this disease do not always work and often have adverse effects. Better treatments for FSGS are need...
Summary: This is a parallel, Phase 2a, double-blind, 6-arm study for the treatment of primary focal segmental glomerulosclerosis (FSGS) or primary minimal change disease (MCD). The purpose of this study is to measure the change in proteinuria and its impact on the rates of remission of nephrotic syndrome with frexalimab, SAR442970, or rilzabrutinib compared with placebo in participants with primary FSGS or...
