PSGN is a kidney disease that can develop after infections caused by bacteria called group A Streptococcus (group A strep). These infections include throat and skin infections like strep throat, scarlet fever, and impetigo.It usually takes about 10 days after the start of symptoms of strep throat or scarlet fever for PSGN to develop.
Warning Signs Usually Point to Kidney Issues
Symptoms of PSGN can include:
- Dark, reddish-brown urine
- Swelling (edema), especially in the face, around the eyes, and in the hands and feet
- Decreased need to pee or decreased amount of urine
- Feeling tired due to low iron levels in the blood (fatigue due to mild anemia)
In addition, someone with PSGN usually has:
- Protein in the urine
- High blood pressure (hypertension)
Treatment Focuses on Managing Swelling, Blood Pressure
Treatment of PSGN focuses on managing symptoms as needed:
- Decreasing swelling (edema) by limiting salt and water intake or by prescribing a medication that increases the flow of urine (diuretic)
- Managing high blood pressure (hypertension) through blood pressure medication
People with PSGN who may still have group A strep in their throat are often provided antibiotics, preferably penicillin.
Serious Complications Include Long-term Kidney Damage
Most people who develop PSGN recover within a few weeks without any complications. While rare, long-term kidney damage, including kidney failure, can occur. These rare complications are more common in adults than children.
