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.)
How is IgA nephropathy caused?
IgA nephropathy is a common glomerular disease and a major cause of uremia. However, the exact cause of IgA nephropathy is not very clear. Current research suggests that it is caused by factors such as infections which stimulate the production of autoantibodies, forming immune complexes that deposit in the glomeruli. This leads to inflammation of the glomeruli, eventually stimulating mesangial cell proliferation and accumulation of extracellular matrix, causing glomerulosclerosis and interstitial fibrosis. IgA nephropathy is a very covert disease, often presenting as asymptomatic hematuria or increased urine protein. Many patients discover this condition incidentally during physical examinations. Some individuals have a history of upper respiratory or gastrointestinal infections before the onset of the disease, followed by the discovery of gross hematuria. IgA nephropathy is more common in children and adolescents.
How should acute nephritis be treated?
Patients with acute nephritis generally have a good prognosis after reasonable and standardized treatment, and rarely develop into chronic nephritis. The main means of treating acute nephritis is symptomatic supportive care, requiring patients to rest in bed during the acute phase. At the same time, spicy food should be avoided and salt intake should be appropriately controlled. If the patient has an infection, sensitive antibiotics should be actively selected for treatment. Additionally, diuretics can be appropriately used for patients with edema, and if the patient also has hypertension, antihypertensive drugs may be used to keep blood pressure within an appropriate range. Of course, some severe cases of acute nephritis may lead to heart failure or renal failure, in which case dialysis should be actively pursued. (Specific medication use should be carried out under the guidance of a doctor.)
How is hypertensive nephropathy treated?
Long-term hypertension can lead to abnormal kidney structure and function, also known as hypertensive nephropathy. Once hypertensive nephropathy is diagnosed, comprehensive treatment measures are often adopted, including both pharmacological and non-pharmacological treatments. In terms of non-pharmacological treatment, patients should maintain a low-salt diet in their daily life, focusing on a light diet, with a daily salt intake of about 4 grams. Regarding pharmacological treatment, the main goal is to control the patient's blood pressure and reduce urinary protein. Medications that can be used include angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists. Any of these medications can be chosen and used long-term to control blood pressure, protect kidney function, and reduce urinary protein. (Medications should be used under the guidance of a physician, and self-medication should be avoided.)
Symptoms of pre-uremia
The pre-uremic stage is the period of chronic renal failure. During the pre-uremic stage, many patients may have no symptoms at all. However, some patients do experience many uncomfortable symptoms, such as back soreness and weakness, fatigue, and feeling cold easily. During this stage, patients may also experience nausea and vomiting, especially pronounced nausea after waking up in the morning, as well as weight loss. Some patients in the pre-uremic stage exhibit symptoms of edema, which can occur in the eyelids, facial area, or in both lower limbs. Additionally, patients may experience feeling cold, anemia, and an increased frequency of urination at night. Of course, some patients may also experience itching of the skin on both lower limbs.
How do you get pyelonephritis?
Pyelonephritis is a clinical type of urinary tract infection, which refers to the inflammatory disease caused by the growth and reproduction of various pathogens in the renal pelvis. Pyelonephritis is usually divided into acute pyelonephritis and chronic pyelonephritis. Acute pyelonephritis is primarily characterized by frequent urination, urgency, painful urination, chills, fever, back pain, overall muscle soreness, and tenderness or percussion pain in one or both kidney areas. Chronic pyelonephritis, on the other hand, shows varying degrees of bilateral renal damage, reduced kidney size, rough surfaces, renal papillary scars, renal tubular atrophy, and chronic inflammation signs such as lymphocyte infiltration in the renal interstitium. Chronic pyelonephritis typically presents with low-grade fever, weight loss, backache, and anemia. Therefore, sufficient attention should be given to pyelonephritis, as chronic pyelonephritis can lead to uremia in patients.
Can you take cold medicine if you have nephrotic syndrome and catch a cold?
People with nephrotic syndrome have particularly weak immune systems, making them especially prone to infections and colds. Once a cold occurs in someone with nephrotic syndrome, the patient often experiences headaches, whole-body muscle soreness, sore throat, nasal congestion, runny nose, and sneezing. In other words, patients with nephrotic syndrome feel very uncomfortable when they catch a cold. If kidney function is normal, it is still possible to take cold medicine. Of course, before using cold medicine, it is essential to follow the doctor's advice for medication treatment. Moreover, after catching a cold with nephrotic syndrome, in addition to taking medication, it is important to rest, consume fresh vegetables and fruits, drink plenty of water, and maintain a light diet. Additionally, it is important to rest, avoid overwork, and if there is a concurrent bacterial infection, sensitive antibiotics should be used for anti-infection treatment, to avoid the recurrence or aggravation of nephrotic syndrome due to infections or colds.
How is pyelonephritis treated?
Whether it is the treatment of acute pyelonephritis or chronic pyelonephritis, first of all, personal hygiene should be emphasized, physical fitness should be enhanced, water intake should be increased, and urination should be frequent. In addition, for patients with acute pyelonephritis, the main treatment is the use of sensitive antibiotics, which can be either semi-synthetic penicillin or cephalosporins, and fluoroquinolone antibiotics can also be used. For chronic pyelonephritis, if the patient has urinary anatomical or functional abnormalities, such as the presence of urinary stones or urinary obstruction, active surgical treatment can be considered to relieve the obstruction. Furthermore, patients with chronic pyelonephritis who also have hypertension and edema can appropriately use antihypertensive drugs and diuretics to control blood pressure and edema, which can play a role in protecting kidney function. (The use of medications should be conducted under the guidance of a doctor.)
