Nephrotic syndrome generally does not cause itchy skin in patients. In patients with nephrotic syndrome, the glomerular filtration barrier is severely damaged, leading to a significant presence of urinary protein and edema, but itchy skin is a rare clinical symptom. If a patient experiences itchy skin, it is recommended to visit the dermatology department of a standard hospital. As such patients may have a disordered immune system, they are prone to various skin issues, such as allergic dermatitis and eczema, which might cause symptoms of itchy skin. However, these are not directly related to nephrotic syndrome.

Do you take steroids for nephrotic syndrome?

Once nephrotic syndrome is diagnosed, corticosteroid therapy becomes a primary treatment, and the commonly used steroid is prednisone. If there is liver damage or the treatment effect of prednisone is not good, oral prednisolone or intravenous methylprednisolone can be used. Due to its long half-life and severe side effects, dexamethasone is now generally less used. The course of treatment with corticosteroids for nephrotic syndrome is relatively long, needing about one to one and a half years. During this process, the use of steroids has three phases: the initial full-dose phase, during which a relatively large dose of the hormone is used for about two to three months; the second phase is a slow reduction process; the third phase is a low-dose maintenance process. Overall, during the use of steroids, patients must regularly follow up at outpatient clinics, and adjust the steroids according to the doctor's advice. One must not arbitrarily reduce the dose or stop the medication, as this can easily lead to a relapse of nephrotic syndrome.

Does nephrotic syndrome easily lead to cerebral infarction?

Nephrotic syndrome is a high-risk factor for cerebral infarction, making patients prone to strokes. This is because patients with nephrotic syndrome excrete large amounts of protein in their urine, which reduces protein concentration in the plasma and disrupts the anticoagulant fibrinolysis system, leading to an increased tendency to form blood clots. These clots are prone to develop in the veins of the lower extremities and the renal veins, and cerebral arteries in the skull are also susceptible to occlusion. Therefore, in such patients, if the plasma albumin level is very low, such as below 20 grams per liter, there is a need for routine use of anticoagulant medications.

Characteristics of Nephrotic Syndrome

The characteristic feature of nephrotic syndrome is that patients may experience edema, which is related to the nature of this disease. The essence of this disease is due to some reason that damages the glomerular capillary filtration barrier. As a result, when blood passes through the glomeruli, it leaks proteins from the blood. A 24-hour urinary protein quantification will exceed 3.5 grams, which constitutes a large amount of urinary protein. Consequently, a large amount of protein is leaked into the urine, causing the protein concentration in the plasma to decrease. This leads to a reduction in the colloidal osmotic pressure of the plasma, causing fluid to move from inside the blood vessels to outside, thus leading to edema. Therefore, the most significant clinical feature of nephrotic syndrome is the potential to cause edema, and severe cases of edema may elevate blood pressure, lead to pulmonary edema, manifesting as difficulty breathing, chest tightness, and shortness of breath.

How to reduce swelling in the feet caused by nephrotic syndrome?

Swelling of the feet is a common phenomenon in nephrotic syndrome. Once swelling occurs, patients feel uncomfortable symptoms and a sensation of heaviness in their feet, so corresponding de-swelling treatment is necessary. How to reduce swelling? Firstly, a low-salt diet is essential to control salt intake, with daily salt consumption around 2 to 3 grams. In addition to this, small doses of diuretics such as hydrochlorothiazide and spironolactone can be used. If the diuretic effect is not satisfactory, other more potent diuretics like furosemide may be added. Of course, the fundamental treatment for foot swelling in nephrotic syndrome involves the use of steroids and immunosuppressants. This treatment works by suppressing the permeability of the glomerular basement membrane and reducing protein leakage, thereby ultimately eliminating the foot swelling.

Characteristics of Nephrotic Syndrome

The characteristics of nephrotic syndrome are defined by significant proteinuria, where significant proteinuria refers to urinary protein exceeding 3.5 grams in 24 hours; hypoproteinemia, which refers to blood albumin levels below 30 grams per liter; edema, which may present in facial and lower limbs, and even severe patients may exhibit generalized edema around both lower limbs; and hyperlipidemia, characterized by increased cholesterol and triglycerides in the blood. These patients may exhibit reduced urine output, edema, and noticeably increased foam in the urine.
