Foods to Avoid with IgA Nephropathy
IgA nephropathy patients are a very common type of glomerular disease. For IgA nephropathy patients, it is crucial to adhere to a light diet, meaning they should avoid foods such as pickles, salted vegetables, kimchi, cured products, smoked products, and barbecues, focusing primarily on fresh vegetables and fruits. Of course, if IgA nephropathy patients also suffer from renal insufficiency, they must avoid various soy products including tofu, bean sprouts, soybean sprouts, mung bean sprouts, and nut-based foods. These foods contain a lot of plant proteins, which can increase the burden on the kidneys, leading to potential renal insufficiency. Additionally, they should not consume foods high in potassium, such as oranges, bananas, pineapples, etc. Therefore, it is essential for IgA nephropathy patients to be cautious with their diet.
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.
Does uremia transmit to others?
Uremia is not contagious to others because it is not an infectious disease. Uremia is a severe renal failure, so patients with uremia can interact, communicate, live, work, and study with healthy people without the need for gastrointestinal or respiratory isolation. Normally, if a patient with uremia is stable, they can engage in sexual activities and the disease will not be transmitted through sexual contact. Uremia usually presents symptoms such as nausea, vomiting, edema, and increased blood pressure. Therefore, patients with uremia need to undergo dialysis treatment. They can choose either hemodialysis or peritoneal dialysis. Dialysis treatment can significantly improve the symptoms of uremia and enhance the quality of life of the patients.
Symptoms of acute nephritis include back pain.
Patients with acute nephritis usually have hematuria as their main symptom. Initially, the condition presents as gross hematuria, but within 1-2 days, the patient transitions to microscopic hematuria, and the gross hematuria disappears. Patients may also experience edema, particularly noticeable in the eyelids and facial area upon waking up in the morning, along with varying degrees of increased urine protein. Typically, acute nephritis patients may also experience nausea, vomiting, abdominal distension, and discomfort in the lower back, but not back pain per se, as back pain is not a symptom of acute nephritis. However, if a patient with acute nephritis does develop back pain, it is crucial to rule out other diseases, such as kidney stones, ureteral stones, acute pyelonephritis, and acute renal infarction, all of which can cause sudden back pain in patients with acute nephritis. Back pain should be taken seriously, and appropriate exams, such as an immediate ultrasound, should be conducted.
What to do if acute nephritis worsens?
Typically, after two to three weeks of treatment, the condition of most patients with acute nephritis can recover. However, if the condition of acute nephritis worsens, patients should return to bed rest and adopt different treatment methods based on their clinical symptoms. If the patient presents with edema, it is essential to maintain a low-salt diet, with daily salt intake less than 2-3 grams. Additionally, the patient's blood pressure must be addressed. If there is a significant rise in blood pressure, it is advisable to start with a low dose of diuretics, which can facilitate urination, fluid excretion, and lower blood pressure. If blood pressure control is inadequate, calcium channel blockers should be considered. Moreover, if a patient with acute nephritis develops acute renal failure, dialysis treatment may be necessary; similarly, if acute heart failure occurs, medications to control blood pressure and dilate blood vessels should be used to reduce the cardiac workload, thereby facilitating recovery from acute nephritis. (Specific medications should be used under the guidance of a physician.)
Precursors of uremia
The kidneys have a very strong compensatory ability. When kidney function is slightly impaired, they can generally still handle the basic physiological functions of the human body through compensation, so patients may feel that everything is normal. Despite the fact that the occurrence and development of uremia is a long and gradually worsening process, which can sometimes be very severe, it is still possible to detect early signs of uremia if one actively seeks them out early on. Early indications of uremia can be identified in time by going to the hospital for urine and blood tests. The early signs of uremia often manifest as general fatigue, which is the symptom most easily overlooked. Other symptoms of early uremia include edema, especially noticeable swelling of the eyelids and facial area after waking up in the morning. If it develops into systemic or persistent edema, the condition is already very serious. Additionally, early-stage uremia patients may also experience an increase in the frequency of nocturnal urination and more foam in the urine, as well as increased blood pressure, and even dizziness, headaches, and a lack of appetite. These are all early signs of uremia.
How to treat IgA nephropathy?
IgA nephropathy has many clinical manifestations and pathological types, and the treatment of IgA nephropathy is selected based on different clinical manifestations and pathological types. Usually, for patients with IgA nephropathy who only show microscopic hematuria, drug treatment is not necessary. They only need to regularly monitor routine urine tests, kidney function, and blood pressure changes in daily life, and must avoid using medications that are toxic to the kidneys. If the patient presents with gross hematuria related to tonsillar infection, tonsillectomy is recommended. If an IgA nephropathy patient has increased urinary protein, and the 24-hour urinary protein quantification exceeds 1g, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers can be used. Of course, for patients with significant proteinuria, steroids or immunosuppressants may also be used. In addition, IgA nephropathy patients can also be treated with traditional Chinese medicine. (Medication use should be under the guidance of a professional doctor.)
Early symptoms of acute nephritis
The occurrence of acute nephritis is related to streptococcal infections and is commonly seen in children. Typically, 1-3 weeks before the onset of acute nephritis, patients often have a history of infections in the throat, upper respiratory tract, or skin. Once acute nephritis occurs, the initial symptoms include hematuria, which can manifest as either gross or microscopic hematuria. There is also the appearance of edema, especially noticeable swelling of the eyelids and facial area upon waking up in the morning, and even a decrease in urine output. Additionally, patients with acute nephritis often experience increased foam in the urine, indicating the presence of proteinuria, as well as general weakness, back pain, nausea, and vomiting. After the onset of acute nephritis, some patients may experience elevated blood pressure and even transient renal failure.
What are the symptoms of acute nephritis?
Acute nephritis is commonly seen in children, and in cases of acute nephritis in children, it is often preceded by an upper respiratory tract infection or skin infection one to three weeks prior to the onset. Once acute nephritis occurs, the most prominent clinical symptom in patients is gross hematuria, though some individuals only show microscopic hematuria, accompanied by an increase in urinary proteins. Additionally, patients with acute nephritis may experience swelling of the eyelids and lower limbs, especially noticeable swelling of the eyelids and facial area upon waking in the morning. Some patients may also experience elevated blood pressure, leading to symptoms such as dizziness and headache. A few may suffer from nausea, vomiting, loss of appetite, reduced urine output, or even symptoms of acute renal failure.
Does stage 2 IgA nephropathy require treatment?
IgA nephropathy can be divided into five stages, where stages one to two are relatively mild, early stages, and generally have a good prognosis. For patients with stage two IgA nephropathy, it is rare for the condition to progress to uremia, but whether treatment is needed largely depends on the clinical manifestations of the IgA nephropathy. If a patient with IgA nephropathy has a 24-hour urinary protein quantification greater than 0.5g, it is advisable to use an angiotensin-converting enzyme inhibitor or an angiotensin II receptor antagonist to protect kidney function and reduce urinary protein. If a stage two IgA nephropathy patient only shows microscopic hematuria, drug treatment is not necessary. However, routine urinalysis and kidney function monitoring should be conducted in daily life, and if an infection occurs, timely anti-infection treatment should be administered. If a stage two IgA nephropathy patient has significant proteinuria, steroid treatment is often required. (Medication should be taken under the guidance of a doctor.)
