Nephrotic Syndrome is a complex kidney disorder that causes severe protein loss in the urine. Symptoms such as edema, high cholesterol, and low albumin in the blood can develop silently, making it easy to miss.
Although the disease has been widely studied, the exact mechanism remains a mystery. Variations in the kidney's filtering capacity and the influence of genetic factors make treatment difficult and require a multidisciplinary approach.
When detected early, treatment can help patients control the disease and prevent serious complications, bringing hope to those affected.
Nephrotic Syndrome causes excessive protein loss through the urine.
What is Nephrotic Syndrome?
Nephrotic Syndrome is a serious disorder involving kidney function. The kidneys lose their ability to filter and maintain important substances in the blood, resulting in the loss of large amounts of protein in the urine. The kidneys, essential for removing waste and balancing nutrients, protect the body from excess unnecessary substances. When kidney function is impaired, a variety of serious complications can arise.
How Nephrotic Syndrome Works
The loss of protein in the urine, also known as proteinuria, is the main feature of Nephrotic Syndrome. This occurs when the glomeruli – the part of the kidney responsible for filtering blood – are damaged. As a result, proteins such as albumin leak out instead of being reabsorbed into the blood.
Clinical Manifestations
Symptoms of Nephrotic Syndrome typically include swelling, especially in the eyes, legs, and abdomen, foamy urine due to high protein levels, along a decrease in energy and general health. The disease can also cause high blood pressure and a susceptibility to infection.
Causes of Nephrotic Syndrome
Nephrotic Syndrome is a complex condition that can arise from a variety of causes, ranging from primary kidney diseases to systemic factors that directly affect kidney function. The structure of the kidney, especially the glomeruli, can be damaged by various external factors, causing protein loss in the urine.
Primary causes
Primary kidney diseases that directly damage the glomeruli include:
- Minimal change disease (MCD): The most common cause in children, this condition causes damage to the cells of the glomeruli without obvious changes on imaging.
- Focal segmental glomerulosclerosis (FSGS): Characterized by uneven fibrosis of the glomerular segments, causing reduced filtration function.
- Membranous nephropathy: An autoimmune disease where the immune system attacks the glomerular filtration membrane, accumulating protein in the urine.
Secondary causes
Systemic diseases, such as:
- Diabetic nephropathy: Long-term high blood sugar can damage the glomeruli, leading to protein loss.
- Systemic lupus erythematosus (lupus nephritis): The immune system attacks kidney tissue, causing inflammation and impaired kidney function.
These factors cause direct damage and create serious complications if not treated promptly.
Symptoms of Nephrotic Syndrome
Nephrotic Syndrome is a medical condition that can manifest itself through a series of distinct symptoms, affecting many systems in the body. These signs arise from a decline in kidney function, causing the body to be unable to maintain the balance of important substances, leading to serious complications.
Edema
One of the most prominent symptoms of Nephrotic Syndrome is edema, especially in areas such as the eyes, legs, and abdomen. The fluid accumulation in the tissues due to protein loss through the urine causes this swelling. Edema can be severe, making the patient feel tired and uncomfortable.
Foamy and discolored urine
Urine may become foamy, a sign of high protein levels. This is the result of protein leaking through the glomerular filtration membrane, directly affecting the quality of urine. Additionally, urine may be dark yellow, a sign of an imbalance in the body.
Other symptoms
In addition, patients may also feel tired, have a reduced ability to fight infections, have high blood pressure, and even experience sudden weight gain due to fluid accumulation. Dyslipidemia can also cause cardiovascular problems, increasing the risk of heart disease.
Diagnosis of Nephrotic Syndrome
Diagnosis of Nephrotic Syndrome is a complex process, requiring a combination of clinical and paraclinical testing methods to accurately determine the cause and extent of kidney damage. Early detection is important to prevent long-term complications.
Urinalysis
Urinalysis is the first step in diagnosing Nephrotic Syndrome. Detecting protein in the urine is a basic sign of the disease. If the amount of protein exceeds the normal level, proteinuria will be confirmed, which is an important indicator in the diagnosis.
Blood tests
Blood tests help assess the extent of kidney damage and the overall condition. Serum albumin test will indicate a decrease in albumin, a typical sign of Nephrotic Syndrome. In addition, cholesterol and kidney function tests (creatinine, BUN) also help determine the patient's condition.
Kidney biopsy
In some cases, a kidney biopsy is performed to determine the exact cause of the disease. This method helps detect damage to the kidney tissue, thereby providing an accurate diagnosis of primary or secondary kidney disease.
Imaging tests
Imaging methods such as kidney ultrasound or CT scan can be used to evaluate the size and structure of the kidney and rule out other diseases that can cause similar symptoms.
Treatment Options for Nephrotic Syndrome
Treatment of Nephrotic Syndrome requires a comprehensive approach to reduce symptoms, prevent complications, and preserve kidney function. The choice of appropriate therapy depends on the underlying cause of the disease and the severity of kidney damage.
Medications
Medications are an integral part of managing Nephrotic Syndrome. Corticosteroids and immunosuppressants are often used to reduce inflammation and control autoimmune diseases such as lupus or Minimal Change Disease. In addition, ACE inhibitors and ARBs help reduce proteinuria and control high blood pressure, an important risk factor for kidney damage.
Diuretics and Cholesterol Medications
Diuretics help reduce swelling by removing excess fluid from the body. Statins are used to lower high cholesterol levels, reducing the risk of cardiovascular disease associated with Nephrotic Syndrome.
Diet and lifestyle changes
Diet plays an important role in treatment. A low-salt, low-protein diet will help reduce the burden on the kidneys and improve edema. In addition, maintaining a healthy lifestyle, including controlling blood pressure and maintaining a healthy weight, can help manage the disease.
Treatment of complications
In addition to the main treatments, management of complications such as infection and thrombosis is essential. The use of anticoagulants helps prevent the risk of blood clots in vulnerable patients.
Complications of Nephrotic Syndrome
Nephrotic Syndrome, if not treated promptly and properly, can lead to many serious complications, affecting the patient's overall health. These complications not only impair kidney function but can also affect other organs in the body, threatening life if not strictly controlled.
Chronic Kidney Disease and Kidney Failure
One of the most serious complications of Nephrotic Syndrome is the development of chronic kidney disease (CKD) or kidney failure. When the kidneys are no longer able to filter waste and maintain the balance of water, salt, and electrolytes in the body, the patient may face the risk of end-stage renal failure, requiring dialysis or a kidney transplant.
Infections and Immunodeficiency
The loss of protein in the urine leads to decreased albumin levels in the blood, weakening the immune system. This increases the risk of infection, especially urinary tract infections and sepsis. Patients may face serious problems if not prevented and treated promptly.
Thrombosis and Cardiovascular Problems
Changes in the structure of the blood, including high cholesterol levels and increased clotting ability, can lead to the formation of blood clots (thrombosis). As a result, these blood clots can travel to the lungs (pulmonary embolism) or other vital organs, causing life-threatening consequences. In addition, the risk of cardiovascular disease, especially due to high cholesterol levels, is also significantly increased in patients with Nephrotic Syndrome.
Prevention and Long-Term Management
Prevention and long-term management of Nephrotic Syndrome require careful attention from patients and healthcare professionals. Although the disease can be difficult to cure, good management of risk factors and appropriate treatment can minimize the progression of the disease and prevent serious complications.
Controlling Underlying Conditions
One of the most important factors in preventing Nephrotic Syndrome is good control of underlying conditions such as diabetes and lupus. Controlling blood sugar in diabetic patients and promptly treating inflammatory flares in lupus will help reduce the risk of serious kidney damage. Monitoring and adjusting the dosage of medications to treat underlying conditions also play an important role in protecting kidney function.
Regular monitoring of kidney function
Regular monitoring of kidney function through blood and urine tests is an integral part of the early detection of abnormal changes. Early detection of increased proteinuria or signs of impaired kidney function will help doctors intervene quickly and minimize the risk of chronic kidney failure.
Healthy diet and lifestyle
A low-salt, low-protein diet with adequate nutrients will help reduce the load on the kidneys, reduce edema, and control blood pressure problems. In addition, maintaining a healthy lifestyle, including regular exercise, not smoking, and weight control, will support patients in maintaining overall health.
Preventing infections and blood clots
Patients with Nephrotic Syndrome are at high risk of infection and blood clots. It is important to get vaccinated and maintain personal hygiene. In addition, doctors may prescribe anticoagulants in some cases to prevent blood clots, especially in patients with high cholesterol levels or who are taking corticosteroids.
Living with Nephrotic Syndrome
Living with Nephrotic Syndrome can be a huge challenge for patients and their families. The complex complications of the disease, combined with the need to adhere to long-term treatment, require not only perseverance but also a comprehensive care plan to maintain quality of life. However, patients can live healthy and active lives with the right support and effective management strategies.
Coping with Daily Life
The daily life of a patient with Nephrotic Syndrome can be severely affected by symptoms such as edema and fatigue. However, adhering to a strict diet and taking regular medications can help control these symptoms. Patients need to understand that although it may be difficult, treatment options and support from healthcare professionals can significantly improve their health condition.
Mental Health and Support
Coping with a chronic illness can be emotionally and psychologically taxing. Concerns about the future, changes in daily life, and dependence on medications can leave patients feeling isolated and stressed. Joining a patient support group, talking to a mental health professional, or seeking support from family and friends are important to help patients cope with these mental challenges.
Advances in Treatment and Research
Thanks to advances in medicine, treatment for Nephrotic Syndrome is becoming more effective. New therapies, such as immunosuppressants and other breakthrough treatments, offer patients hope. With ongoing research, potential treatments may help patients live longer and minimize the impact of the disease.
