Glomerulonephritis
What Went Wrong?
Glomerulonephritis is an inflammation of the glomerulus. There are two
types of glomerulonephritis:
Acute: This might occur up to 6 weeks following a respiratory tract
streptococcal bacterial infection or from a skin infection as a result of
antigen/antibody groups trapped in the tubules causing edema that
decreases filtering and thus causes urine to be retained.
Chronic: An abnormal immune system, bacterial or viral infection, dis-
ease or toxin causes progressive dysfunction of the glomerulus over the
years.
Signs and Symptoms
Acute:
- Lower than normal urine output (oliguria)
- Fever
- Edema of the face and extremities
- Hypertension
- Lethargy
Chronic: - Lower than normal urine output (oliguria)
- Hypertension
- Does not respond to treatment for acute glomerulonephritis
Test Results
Acute:
- Urine analysis: Blood in the urine (hematuria), cola-color urine,
high specific gravity, and protein in the urine (proteinuria) - Serum: Elevated creatinine and blood urea nitrogen (BUN)
- Antistreptolysin-O test: Positive for streptococcal bacteria
- Throat culture: Positive for streptococcal bacteria
- Renal ultrasound: Shows enlarged kidneys
- Renal biopsy: Positive for glomerulonephritis
Chronic: - Urine analysis: Blood in the urine (hematuria), cola-color urine, high
specific gravity, and protein in the urine (proteinuria) - Serum: Elevated potassium (hyperkalemia), creatinine, and BUN
- Computed tomography (CT) scan: Shows decreased size of kidneys
- Ultrasound: Shows decreased size of kidneys
- Renal biopsy: Shows glomeruli scarring and tests positive for
glomerulonephritis - Electrocardiogram (ECG): Abnormal; possibly indicating hyperkalemia
