Nephrotic syndrome
Syndrome of kidney disease with manifestations of calcium deficiency
In the state of nephrotic syndrome, if there is a calcium deficiency, it may cause the patient's limbs to twitch, especially sudden twitches and pain in both lower limbs during sleep at night, waking the patient from sleep. If calcium deficiency persists for a long time, it may lead to osteoporosis in the patient, such as osteoporosis of the femoral head, which presents with hip pain, and necrosis of the femoral head, potentially affecting the patient's ability to walk. In children, calcium deficiency may cause night-time convulsions, and external manifestations such as hunchback, pigeon chest, and square skull might appear.
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.
Conditions for discontinuing medication for nephrotic syndrome
The main clinical manifestations of nephrotic syndrome are significant proteinuria and hypoproteinemia, along with varying degrees of hyperlipidemia and edema. Nephrotic syndrome often requires treatment with corticosteroids. The general principle for using steroids is to start with a sufficient dosage and administer it slowly, maintaining it for a long duration, approximately around one year. Therefore, the conditions for discontinuing medication in nephrotic syndrome include: if the patient has been treated with steroids for about a year, and the proteinuria has resolved, 24-hour urinary protein quantification is normal, there is no edema, blood albumin levels have returned to normal, and kidney function is also normal, then discontinuation of steroid treatment can be considered. Of course, after stopping the medication, it is essential to regularly visit the hospital for monitoring of routine urine tests, kidney function, and blood pressure to prevent the recurrence of nephrotic syndrome due to infections or fatigue.
Causes of vomiting in nephrotic syndrome
Patients with nephrotic syndrome may experience vomiting for several possible reasons. First, nephrotic syndrome causes severe edema in patients, including edema of the gastrointestinal tract. This state of edema may lead to reduced gastrointestinal motility and symptoms of nausea and vomiting. Furthermore, patients with nephrotic syndrome have low plasma protein levels and poor immune function, making them prone to infections. If there is an infection in the gastrointestinal tract, patients may exhibit clinical symptoms of vomiting as well as potentially experiencing diarrhea, abdominal pain, and so on. Additionally, some patients experience vomiting due to the side effects of medications used during the treatment of nephrotic syndrome.
Manifestations of recovery from nephrotic syndrome
In principle, there is no concept of complete recovery for nephrotic syndrome. The condition of nephrotic syndrome can be alleviated and controlled to the greatest extent, but it cannot be completely cured. When the condition is alleviated, the patient's glomerular filtration barrier is repaired, resulting in a reduction in proteinuria and a decrease in urinary foam clinically. Once the patient's urinary protein decreases, the plasma protein concentration will gradually increase. Thus, water moves back from outside to inside the blood vessels, leading to a reduction in edema. These clinical signs all indicate an improvement in the condition of nephrotic syndrome. Of course, to assess the condition, it is still necessary to rely on the patient undergoing a 24-hour quantitative urine protein test.
Can people with nephrotic syndrome eat strawberries?
Patients with nephrotic syndrome can eat strawberries in moderate amounts. Patients with nephrotic syndrome typically have urinary protein levels exceeding 3.5g in 24 hours, along with noticeable symptoms of edema. It is essential for these patients to control their intake of water, especially those with severe edema, as excessive water intake can further exacerbate the swelling. Additionally, patients should limit their intake of plant proteins, follow a low-salt diet, and avoid heavy consumption of oils and fatty foods. From the above perspectives, it is generally acceptable for patients with nephrotic syndrome to eat strawberries in moderation. Strawberries contain very little plant protein and will not increase urinary protein levels. Although strawberries do not contain much salt, patients with nephrotic syndrome still need to consume them in moderation due to their high water content.
Precursors of relapse of nephrotic syndrome
Nephrotic syndrome is characterized by patients having 24-hour urinary protein quantification exceeding 3.5g and blood plasma albumin levels lower than 30g/L. This condition can be long-lasting. Some patients, after treatment, can have their condition effectively controlled, but there is still a possibility of relapse. Such relapses often occur after the patient has been overworked or has caught a cold, but there are also some patients who do not have such triggers. When the condition relapses, the urinary protein level increases again, which might lead to an increase in urine foam. Patients might experience significant swelling in the lower limbs and face among other areas, suggesting a relapse of nephrotic syndrome, and it is important to go to the hospital for relevant tests promptly.
What should not be eaten with nephrotic syndrome?
Patients with nephrotic syndrome, if the patient has obvious edema, should limit salt intake to between two to three grams per day. It is suggested to consume foods rich in polyunsaturated fatty acids, such as vegetable oils, as well as foods rich in soluble fiber, such as oats. They should also receive a normal amount of 0.8 to 1 gram of high-quality protein per kilogram of body weight per day, mainly from egg whites, milk, lean meat, and fish. Calorie intake should be sufficient, and patients with nephrotic syndrome should eat less salty and pickled foods and consume less animal fat.
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.
Is nephrotic syndrome easy to treat in children?
The diagnostic criteria for nephrotic syndrome are a 24-hour urinary protein quantification exceeding 3.5g and plasma albumin levels below 30g/l. This is due to severe damage to the glomerular capillary network, which has many pathological types since there are various components to the glomerular capillaries, and damage to different components is referred to as different pathological types. Among children, the most common pathological types are minimal change disease and mesangial proliferative glomerulonephritis. These two types are relatively easier to treat. Most children are sensitive to steroid medication. However, treatment becomes difficult with other pathological types, such as focal segmental glomerulosclerosis, which shows less sensitivity to steroids. (Medication use should be under the guidance of a doctor.)
