Overview

Glomerulonephritis is a kidney condition characterized by inflammation of the glomeruli, which are tiny filters in the kidneys responsible for removing excess fluids, electrolytes, and waste from the bloodstream. This condition can be acute or chronic and may lead to kidney damage if not treated promptly.

Types

Glomerulonephritis can be categorized based on its cause and how it presents. The main types include:

• Acute Glomerulonephritis: Sudden onset of symptoms, often following an infection such as strep throat.
• Chronic Glomerulonephritis: Develops gradually over time and can lead to long-term kidney damage.
• Primary Glomerulonephritis: Occurs as a primary kidney disease without any other underlying conditions.
• Secondary Glomerulonephritis: Associated with other diseases such as lupus, diabetes, or infections.

Signs of Glomerulonephritis

The signs and symptoms of glomerulonephritis can vary depending on the type and severity of the condition. Common symptoms include:

• Hematuria: Blood in the urine, which can make urine appear pink, red, or cola-colored.
• Proteinuria: Excessive protein in the urine, leading to frothy urine.
• Edema: Swelling in the face, hands, feet, and abdomen due to fluid retention.
• Hypertension: High blood pressure.
• Fatigue: General feeling of tiredness and lack of energy.
• Oliguria: Reduced urine output.

Symptoms of Acute Glomerulonephritis

Early signs and symptoms of acute glomerulonephritis include:

• Puffiness in the facial area
• Decrease in urine output
• Cola-colored or red urine
• Coughing due to extra fluid in the lungs
• High blood pressure

Symptoms of Chronic Glomerulonephritis

Chronic glomerulonephritis can develop without significant symptoms. Some notable symptoms include:

• Swelling around the ankles and face
• Frequent urination at night
• Bubbly or foamy urine due to excess protein
• High blood pressure
• Simple urine tests may show the presence of protein and red blood cells

Symptoms of Kidney Failure

While many patients with acute glomerulonephritis exhibit the above symptoms, those with chronic glomerulonephritis may have minimal symptoms even with significant kidney function decline. Symptoms of kidney failure include:

• Lack of appetite
• Nausea or vomiting
• Fatigue and insomnia
• Dry, itchy skin
• Swelling of the face, feet, or body
• Decreased urine output
• Shortness of breath

Causes of Glomerulonephritis

Glomerulonephritis can be caused by various factors, including:

• Infections:
  • Post-streptococcal glomerulonephritis: Occurs after infections with certain strains of streptococcus bacteria.
  • Bacterial endocarditis: An infection of the inner lining of the heart.
  • Viral kidney infections: Includes infections caused by viruses like HIV.
• Autoimmune Diseases: Autoimmune diseases occur when the immune system mistakenly attacks healthy tissues. Examples include:
  • Lupus: A systemic autoimmune disease that can affect the kidneys.
  • Goodpasture's syndrome: An autoimmune condition where antibodies attack the lungs and kidneys.
  • IgA nephropathy: A kidney disease caused by deposits of the protein immunoglobulin A (IgA) inside the glomeruli.
• Vasculitis: Vasculitis refers to inflammation of the blood vessels, which can impact kidney function. Types include:
  • Polyarteritis: A rare disease that causes inflammation of small and medium-sized arteries.
  • Granulomatosis with polyangiitis: An inflammation of the blood vessels that can affect various organs.
• Sclerotic Conditions: These diseases cause scarring of the glomeruli, leading to decreased kidney function. Conditions include:
  • High blood pressure: Long-term uncontrolled high blood pressure can damage the kidneys.
  • Diabetic nephropathy: Kidney damage resulting from diabetes.
  • Focal segmental glomerulosclerosis: A condition that causes scarring in the kidney’s filtering units.
• Other Causes:
  • Genetic factors: Some forms of chronic glomerulonephritis are hereditary, such as Alport syndrome, which can also affect hearing and vision.
  • Cancer: Certain cancers, including gastric cancer, lung cancer, and chronic lymphocytic leukemia, have been linked to glomerulonephritis.

Diagnosis

Diagnosing glomerulonephritis involves several steps:

• Medical History and Physical Exam: Review of symptoms and medical history, including any recent infections or illnesses.
• Urine Tests: To detect blood, protein, and other abnormalities in the urine.
• Blood Tests: To check kidney function and identify any underlying conditions.
• Imaging Tests: Such as ultrasound or CT scan to visualize the kidneys.
• Kidney Biopsy: A small sample of kidney tissue is taken for analysis to determine the exact type and cause of glomerulonephritis.

Risk Factors for Glomerulonephritis

Several risk factors can increase the likelihood of developing glomerulonephritis, including:

• A family history of kidney disease
• Autoimmune conditions such as lupus or rheumatoid arthritis
• Viral infections like strep throat or hepatitis B
• Use of certain medications, including antibiotics and blood pressure medications
• Exposure to toxins such as lead or mercury
• Certain medications, like gold compounds

Treatment

The treatment for glomerulonephritis depends on the underlying cause, severity, and type of the condition. It may involve:

• Medications:
  • Corticosteroids: To reduce inflammation.
  • Immunosuppressants: To control the immune system's activity.
  • Antihypertensives: To manage high blood pressure.
  • Diuretics: To reduce fluid retention.
• Lifestyle Changes:
  • Dietary Modifications: Reducing salt, protein, and fluid intake to manage symptoms.
  • Exercise: Regular physical activity to improve overall health.
• Dialysis: In severe cases where kidney function is significantly impaired.
• Kidney Transplant: In end-stage kidney disease, a kidney transplant may be necessary.

FAQ

• What causes glomerulonephritis? Glomerulonephritis can be caused by infections, autoimmune diseases, vasculitis, and other conditions that affect the kidneys.
• Can glomerulonephritis be cured? Treatment can manage symptoms and slow the progression of the disease, but some forms of glomerulonephritis may not be completely curable.
• How is glomerulonephritis diagnosed? Diagnosis involves urine and blood tests, imaging studies, and often a kidney biopsy.
• What are the common treatments for glomerulonephritis? Treatments include medications to control inflammation and blood pressure, lifestyle changes, and in severe cases, dialysis or a kidney transplant.
• Can lifestyle changes help manage glomerulonephritis? Yes, dietary modifications, regular exercise, and avoiding smoking can help manage symptoms and improve overall health.

Conclusion

Glomerulonephritis is a serious kidney condition that requires prompt medical attention. With appropriate treatment and lifestyle modifications, many people with glomerulonephritis can manage their symptoms and maintain a good quality of life. If you suspect you have glomerulonephritis or are experiencing any related symptoms, it is important to seek medical advice for proper diagnosis and treatment.
