Symptoms of Allergic Purpura Nephritis
Kidney damage caused by allergic purpura is called allergic purpura nephritis. This disease is commonly seen in children. Once allergic purpura nephritis occurs, the typical clinical symptoms in patients include joint pain, recurrent rashes on both lower limbs, and abdominal pain. Of course, some patients may also experience gastrointestinal bleeding and the passing of black stools. The main clinical manifestations concerning the kidneys are hematuria and changes in urine color, which can be macroscopic or microscopic hematuria, increased urine foam, and proteinuria. Of course, some patients may also experience edema, especially noticeable swelling of the eyelids and facial area upon waking up in the morning, as well as increased blood pressure. In severe cases of allergic purpura nephritis, patients may also experience renal dysfunction and more.
Is IgA nephropathy stage 2 serious?
IgA nephropathy, when classified according to the World Health Organization, is divided into five stages. Stage 2 IgA nephropathy generally indicates that the patient has a relatively mild condition, with only mild lesions. More than half of the glomeruli are normal, and only a small portion of the glomeruli show increased mesangial cells and glomerulosclerosis. Generally, crescent formations do not occur. Clinically, patients with Stage 2 IgA nephropathy typically exhibit proteinuria and hematuria, usually with normal blood pressure and normal kidney function. Therefore, for patients with Stage 2 IgA nephropathy, it is crucial to maintain a regular lifestyle, avoid infections and fatigue, and refrain from using nephrotoxic drugs. In cases of infection, it is important to actively control the infection. Of course, if the patient's proteinuria exceeds 0.5g, angiotensin-converting enzyme inhibitors can be used to reduce proteinuria and simultaneously protect kidney function.
What are the symptoms of hydronephrosis?
If it is mild hydronephrosis, patients usually do not have obvious clinical symptoms; if it is moderate to severe hydronephrosis, patients mainly experience discomfort and pain in the lower back, and may even have abdominal distension. Once hydronephrosis is complicated by bacterial infection, symptoms may include chills, fever, frequent urination, urgent urination, and general muscle soreness, etc. If there is long-term and extensive hydronephrosis, it can lead to chronic obstructive kidney disease, with symptoms including reduced urine output, swelling of the lower limbs, general fatigue, poor appetite, and increased blood pressure. Patients may experience dizziness, anemia, and decreased kidney function. Therefore, attention must be paid to hydronephrosis. In cases of mild hydronephrosis, the main approach is follow-up and observation. If the hydronephrosis is severe, kidney function tests are required, and surgical drainage should be performed to treat the hydronephrosis.
How long does it take to cure acute nephritis?
Acute nephritis is commonly seen in children. About 1 to 3 weeks before the onset of acute nephritis, many patients have a history of infections in the throat, upper respiratory tract, or skin. Once acute nephritis occurs, the symptoms typically include obvious signs such as hematuria, edema, and high blood pressure. In severe cases, renal dysfunction may also occur. How long does it take to cure acute nephritis? The duration largely depends on the severity of the patient's condition and the timeliness of the treatment. Most patients with acute nephitis can be cured in about two to three weeks with appropriate treatment. That is to say, after two to three weeks of treatment, the patient's hematuria will disappear, the edema will subside, and the blood pressure will return to normal. At this point, the patient can get out of bed and move around indoors.
Will IgA nephropathy be inherited?
The pathogenesis of IgA nephropathy is currently not very clear, but it is certain that IgA nephropathy is not a hereditary disease. However, although IgA nephropathy is not hereditary, many clinical phenomena suggest that there is a familial aggregation of IgA nephropathy, meaning that often, the parents of patients with IgA nephropathy also tend to have children with the condition. Of course, IgA nephropathy patients are usually adolescents and predominantly males. The main clinical manifestations include recurrent episodes of gross hematuria or persistent microscopic hematuria, which might be accompanied by increased urinary protein. Typically, some patients with IgA nephropathy may experience abnormal renal function, elevated blood pressure, and even develop uremia. Therefore, IgA nephropathy must be taken seriously and requires regular follow-up of routine urine changes.
What are the symptoms of diabetic nephropathy?
Kidney disease caused by diabetes is called diabetic nephropathy. In the early stages, patients may not have any noticeable discomfort, while some may experience soreness and discomfort in the lower back. However, as diabetic nephropathy progresses, with further increase in urinary protein, patients will see more foam in their urine and may also experience swelling of the eyelids and lower limbs. Once diabetic nephropathy progresses to the stage of uremia, patients will exhibit symptoms such as nausea, vomiting, general weakness, loss of appetite, increased frequency of urination at night, significant increase in blood pressure, and reduced urine output. Additionally, symptoms of anemia may also occur. Therefore, diabetic nephropathy must be given adequate attention to prevent the onset of uremia.
How can vomiting be alleviated in chronic renal failure?
There are many reasons why patients with chronic kidney failure experience vomiting. To alleviate vomiting, it is first necessary to clarify the cause of vomiting. Generally, if vomiting is caused by an excess of toxins, dialysis treatment may be needed at this time. If it is due to chronic gastritis, drugs that protect the gastric mucosa are needed. Additionally, if it is due to electrolyte disorders, it is essential to correct the electrolyte disturbance to alleviate the symptoms of vomiting. Furthermore, if the vomiting is caused by an infection leading to gastroenteritis, anti-infection drugs are required. Also, some patients with chronic kidney failure may experience nausea and vomiting due to very high blood pressure, which can lead to increased intracranial pressure; in this case, it is necessary to control the blood pressure and reduce intracranial pressure.
Can IgA nephropathy affect menstruation?
IgA nephropathy is a very common glomerular disease in the department of nephrology and is often seen in adolescents, affecting both males and females. Generally, IgA nephropathy itself does not affect menstruation. However, if hormones or immunosuppressants are used during the treatment of IgA nephropathy, it may affect the menstrual cycle or the amount of menstrual flow. In other words, some patients with IgA nephropathy may experience delayed menstruation, reduced menstrual flow, or even increased menstrual flow while using these medications. Therefore, for patients with abnormal menstruation, it is important to report to the doctor in a timely manner and to actively undergo relevant examinations to rule out other causes. If there are no other factors, medication treatment can continue while regularly monitoring kidney function and changes in routine urine tests.
Symptoms of hydronephrosis
Hydronephrosis itself may not have any symptoms, but when hydronephrosis significantly increases, patients can feel soreness and discomfort in the lumbar region or upper abdomen. If the hydronephrosis is caused by urinary tract stones blocking the passage, patients often experience kidney pain and visible blood in the urine; if it is caused by congenital narrowing, it is prone to be complicated by urinary tract infections, with symptoms such as chills, fever, back pain, frequent urination, urgency, and painful urination. Sometimes, hydronephrosis occurs intermittently, with the patient experiencing abdominal pain, nausea, vomiting, and reduced urine output during an episode. The pain disappears after a few hours, followed by the excretion of a large amount of urine. This condition is often seen in ureteral obstruction. Of course, prolonged hydronephrosis can lead to renal failure, causing symptoms such as fatigue, poor spirit, anemia, and even swelling.
What should I do about the high fever caused by nephrotic syndrome?
Patients with nephrotic syndrome, due to long-term use of steroids, have particularly weak resistance and are prone to various infections. High fever is a common symptom in patients with nephrotic syndrome after an infection. Once a high fever due to infection occurs in nephrotic syndrome, it must be taken seriously because infections are often a significant trigger for the relapse or worsening of the condition. Once the condition worsens, patients often experience heavy proteinuria, hypoalbuminemia, edema, and declining kidney function. Therefore, it is crucial to go to the hospital in a timely manner after the onset of high fever for medical treatment, and to conduct routine blood and urine tests, kidney function tests, and chest X-rays to determine the cause of the patient's high fever, whether it is a viral or bacterial infection. Besides, it is important to drink plenty of water, urinate frequently, rest in bed, reduce outdoor activities, and avoid fatigue. If a viral infection causes the fever, antiviral medications that clear heat and detoxify should be used. If a bacterial infection causes the fever, sensitive antibiotics should be used for symptomatic treatment. (Medications should be used under the guidance of a doctor.)
