Glomerulonephritis (GN) is a serious kidney disease affecting millions worldwide. Inflammation of the glomeruli, the kidneys' filtering units, impairs their ability to remove waste and maintain the body's water and salt balance.
This disease can lead to chronic kidney failure and dangerous complications if not detected and treated promptly. Understanding GN's causes, symptoms, and treatments is essential for prevention and improving the patient's quality of life.
Glomerulonephritis can cause swelling, high blood pressure, and kidney damage.
What is Glomerulonephritis?
Glomerulonephritis (GN) is a serious condition that occurs when the filtering units of the kidneys, called glomeruli, become inflamed. These infections affect the kidneys' ability to filter waste and excess fluid, leading to a buildup of toxins in the body. The changes in kidney function can be severe, causing long-term damage and even kidney failure if not treated promptly.
Structure and Function of Glomeruli
Glomeruli are a complex system of small blood vessels that filter the blood, removing waste products and excess while retaining essential components such as proteins and blood cells. When inflamed, this filter layer no longer functions effectively, causing waste products, including proteins and blood cells, to leak into the urine.
Classification of Glomerulonephritis
Glomerulonephritis can be classified into two main groups: acute and chronic. Acute glomerulonephritis usually appears suddenly and can cause edema, high blood pressure, and rapid decline in kidney function. Meanwhile, chronic glomerulonephritis progresses slowly and can lead to chronic kidney failure if not properly monitored and treated.
Causes of Glomerulonephritis
Glomerulonephritis (GN) results from inflammation or damage to the glomeruli in the kidneys, and its causes can be extremely diverse. These factors can be related to infections, autoimmune disorders, or other chronic diseases, each with its mechanism for affecting kidney function.
Infections
One of the most common causes of GN is infection. Post-streptococcal glomerulonephritis is a typical example, which occurs after a Streptococcus infection. In addition, viruses such as hepatitis B, hepatitis C, and HIV can also cause immune reactions that damage the kidneys.
Autoimmune Disorders
Autoimmune diseases such as systemic lupus erythematosus and IgA nephropathy are other common causes. In these cases, the body's immune system mistakenly attacks healthy cells in the kidneys, causing inflammation and damage to the glomeruli. In addition, Goodpasture syndrome, another autoimmune disease, can also cause severe and dangerous GN.
Genetic Factors and Chronic Diseases
Genetics plays an important role in developing GN, especially in disease forms such as hereditary glomerulonephritis. In addition, chronic diseases such as diabetes and vasculitis can also increase the risk of developing GN, leading to permanent kidney damage if not detected and treated early.
Symptoms of Glomerulonephritis
Glomerulonephritis (GN) causes serious symptoms that reflect the deterioration of the kidneys and the body's filtering system. These symptoms can appear suddenly in the acute form or develop slowly in the chronic form, depending on the extent of kidney damage.
Blood in the Urine (Hematuria)
One of the typical signs of GN is the presence of blood in the urine, giving the urine a pink or brown color. This is the result of red blood cells leaking from damaged glomeruli, impairing the kidneys' filtering function.
Protein in the Urine (Proteinuria)
The presence of protein in the urine is a clear sign of GN. Protein is not normally present in the urine, but when the glomeruli become inflamed, they can no longer contain the protein, causing it to be excreted. This can lead to swelling, as the body loses too much important protein.
Edema and High Blood Pressure
Edema (swelling) is a common symptom, often appearing on the face, hands, feet, and ankles. A fluid buildup in the body causes this due to the kidneys' inability to remove it effectively. High blood pressure (hypertension) is another manifestation of GN, as damaged kidneys cannot regulate the body's balance of salt and water, leading to increased blood pressure.
Fatigue and Decreased Urine Output
In addition to the above symptoms, the person may feel tired, lack energy, and have decreased urine output. Decreased kidney function prevents the body from excreting enough waste and toxins, leading to lethargy and discomfort.
Diagnosis of Glomerulonephritis
Diagnosis of Glomerulonephritis (GN) requires a combination of tests to assess the extent of kidney damage and determine the cause of the disease. Because the symptoms of GN can easily be confused with other diseases, the diagnostic process requires careful and thorough care from specialists.
Urine Test
One of the first steps in diagnosing GN is a urinalysis. This test looks for signs of protein (proteinuria) and blood (hematuria) in the urine, two typical manifestations of kidney inflammation. The presence of protein and red blood cells in the urine indicates a severe reduction in the filtering ability of the glomeruli.
Blood Test
Blood tests help assess kidney function through indicators such as serum creatinine, urine urea nitrogen (BUN), and glomerular filtration rate (GFR). These tests help determine the extent of kidney function loss and can provide information about the extent of glomerular damage.
Imaging
Imaging tests such as renal ultrasound or computed tomography (CT) scans can be used to check the size and shape of the kidneys and detect abnormalities such as kidney stones or tumors. However, these techniques are mainly used to rule out other conditions.
Kidney Biopsy
When these tests are not enough to determine the cause or extent of GN, a kidney biopsy may be performed. Through a biopsy, a doctor can take a sample of kidney tissue for microscopic analysis, which can help determine the exact type of GN and the appropriate treatment.
Treatment Options for Glomerulonephritis
Glomerulonephritis (GN) treatment depends on the cause, the extent of kidney damage, and the patient's clinical condition. Treatment goals are to reduce inflammation, preserve kidney function, and prevent serious complications, such as chronic kidney failure.
Inflammatory Medications
Corticosteroids and immunosuppressants such as cyclophosphamide or azathioprine are commonly used to control inflammation and reduce abnormal immune responses. These medications are particularly effective in cases of GN with autoimmune causes, such as systemic lupus erythematosus or IgA nephritis.
Antihypertensive Medications
In cases of GN accompanied by high blood pressure, ACE inhibitors or angiotensin receptor blockers (ARBs) control blood pressure and protect the kidneys. These medications help lower blood pressure and protect the blood vessels of the kidneys from further damage.
Diuretics and Dietary Modifications
Diuretics are used to reduce swelling and control fluid buildup in the body. At the same time, GN patients are often advised to follow a low-salt and low-protein diet to reduce the kidney load and prevent disease progression.
Dialysis and Kidney Transplantation
In cases of severe GN, with acute or chronic kidney failure, dialysis may be necessary to remove waste products and toxins from the body. In cases of end-stage kidney failure, kidney transplantation may be a long-term treatment option to restore kidney function and improve quality of life.
Complications of Glomerulonephritis
Glomerulonephritis (GN), when not treated or controlled promptly, can lead to many serious complications with long-term effects on the health of the kidneys and other organs. These complications can appear even in the early stages of the disease or develop slowly over time.
Chronic Kidney Failure
One of the most serious complications of GN is chronic kidney failure when kidney function is irreversibly reduced. When the glomeruli become severely inflamed and damaged, the kidneys can no longer filter waste and maintain the balance of water and salt in the body, leading to a buildup of toxins and fluid. This can progress to end-stage kidney failure, requiring dialysis or a kidney transplant.
High Blood Pressure and Heart Problems
High blood pressure is a common complication of GN because when the kidneys are damaged, they cannot properly regulate the body's water and salt levels. Prolonged high blood pressure increases the risk of heart disease, stroke, and heart failure, creating a vicious cycle that increases kidney damage.
Nephrotic Syndrome
In severe cases of GN, patients may develop nephrotic syndrome, a condition characterized by severe protein loss in the urine. This leads to decreased albumin in the blood, causing edema (swelling) throughout the body, especially in the face, hands, and feet. This syndrome can reduce quality of life and cause problems with blood clotting and infection.
Infectious and Thrombotic Complications
Patients with GN, especially those with kidney failure, are at increased risk of infections due to a weakened immune system. In addition, the accumulation of fluid and protein in the body can increase the risk of blood clots, leading to thrombotic complications.
Prevention and Risk Reduction
Prevention and risk reduction of developing Glomerulonephritis (GN) is an important part of a kidney health strategy. These measures not only reduce the risk of developing the disease but also prevent the progression of kidney damage and dangerous complications.
Prevention of Infections
One of the important factors in preventing GN is protecting the body from infections, especially bacterial infections such as strep throat, which can lead to post-infectious glomerulonephritis. Prompt treatment of respiratory and urinary tract infections is important to prevent the development of GN. Practicing personal hygiene measures such as regular hand washing and vaccination against infectious diseases also help reduce the risk.
Manage Underlying Conditions
Autoimmune diseases such as systemic lupus erythematosus or IgA nephritis can increase the risk of developing GN. Good control of these conditions through medication and regular monitoring can help reduce the risk of kidney inflammation. In addition, patients with diabetes or high blood pressure need to closely control these health indicators to protect the kidneys.
Maintain a Healthy Lifestyle
A reasonable diet, especially one that limits salt and protein, can help reduce the kidney load. Maintaining a healthy body weight and regular physical activity are important factors in protecting kidney function. Additionally, avoiding smoking and minimizing stress levels are ways to protect the kidneys in the long term.
Living with Glomerulonephritis
Living with Glomerulonephritis (GN) requires major lifestyle changes and long-term healthcare strategies. Understanding the condition, managing symptoms, and maintaining ongoing medical care is important to prevent dangerous complications.
Continuous Kidney Health Monitoring
GN patients must closely monitor their kidney health through regular blood and urine tests. This helps detect any early signs of kidney failure or progression. Doctors will prescribe appropriate treatments based on the test results, ensuring that the kidneys continue to function effectively.
Psychological and Spiritual Support
Living with GN can cause feelings of anxiety, stress, and depression, especially when faced with long-term health problems and the risk of kidney failure. Participating in support groups and counseling can help patients share their experiences and find comfort during treatment. Relaxation techniques like yoga and meditation can also help reduce stress.
Raising Nutrition Awareness
A proper diet is an important factor in maintaining kidney health. GN patients must eat less salt, limit protein, and monitor potassium and phosphorus intake to minimize the kidney burden. Working with a dietitian can help develop a menu appropriate for the condition while maintaining overall health.
