Acute Nephritis Pathological Characteristics
The pathological features of acute nephritis include enlarged kidneys, and under the light microscope, there is diffuse proliferation of glomeruli, capillary endothelial cells, and mesangial cells. During the acute phase, there can be infiltration of neutrophils and mononuclear cells. In severe cases, constriction or occlusion of the capillary loops occurs, and the renal interstitium has edema and infiltration of inflammatory cells. Under immunofluorescence, there are deposits of IgG and C3 appearing as granular deposits along the glomerular capillary walls and mesangial areas. Under electron microscopy, there are hump-shaped electron-dense deposits beneath the glomerular epithelium. Acute nephritis is commonly seen in children, characterized by a sudden onset and symptoms such as hematuria, increased urinary protein, edema, and elevated blood pressure, even transient renal function decline may occur.
How should uremia patients rest?
Adequate rest plays a very important role in the recovery of patients with uremia. If the condition of the uremia patient is in an acute phase, for example, if the patient feels palpitations, chest tightness, shortness of breath after activities, or even has obvious edema and high blood pressure, the patient should rest in bed and try to avoid getting out of bed. They should eat and take care of personal hygiene while in bed. If they feel chest tightness, they can also use oxygen. Once the condition of the uremia patient has stabilized, especially after undergoing hemodialysis treatment, and the symptoms of uremia have improved, they can rest out of bed and should ensure they get seven to eight hours of sleep daily. Only through sufficient sleep can the patient's mental state significantly improve. During the rest period, patients can also engage in appropriate recreational activities, such as outdoor walks, singing, and other activities.
Causes of Uremia
Uremia is a syndrome caused by the progressive development of various chronic kidney diseases, eventually leading to renal failure in patients, where the kidneys are unable to promptly eliminate excess water, various electrolytes, and toxins from the body. There are many causes of uremia; chronic nephritis, diabetic nephropathy, and hypertensive nephropathy are the most common causes. Other causes include chronic tubulointerstitial nephritis, chronic pyelonephritis, chronic obstructive nephropathy, toxic nephropathy, hereditary nephritis, renal vascular diseases, and lupus nephritis. Once uremia occurs, the preferred treatment is dialysis therapy, which can be either hemodialysis or peritoneal dialysis. Only after dialysis treatment can the life of a patient with uremia be prolonged.
What are the symptoms of acute nephritis?
Acute nephritis is commonly seen in children. Most cases of acute nephritis are preceded by a history of streptococcal infection one to three weeks before the onset. Once acute nephritis occurs, the main symptoms include the development of edema, especially swelling of the eyelids and face after waking up in the morning. Additionally, patients with acute nephritis will also experience hematuria, which can be visible or microscopic, with increased foam in the urine and a change in color, and even a decrease in urine output. Of course, patients with severe acute nephritis will also experience a significant increase in blood pressure, leading to nausea, vomiting, headaches, palpitations, chest tightness, shortness of breath, and an inability to lie flat, resulting in heart failure. Therefore, patients with acute nephritis need to undergo reasonable and standardized treatment to avoid complications.
Is acute nephritis serious?
Acute nephritis is commonly seen in children, predominantly affecting male children. Often before the onset, there's a history of upper respiratory tract infection or skin infection. One to three weeks after these infections, patients may develop hematuria, swelling of the eyelids and lower extremities, and increased urinary protein. The severity of acute glomerulonephritis can vary; patients with milder forms of acute glomerulonephritis can be cured through appropriate treatment and standardized medication. However, if acute glomerulonephritis is not detected timely and treated properly, it can lead to severe complications, including uremia, heart failure, hypertensive encephalopathy, and other clinical manifestations. Therefore, acute nephritis must be taken seriously to avoid severe complications. Of course, with proper treatment, most patients with acute nephritis can fully recover and have a good prognosis.
acute nephritis symptoms
Acute nephritis is commonly seen in children and occurs more in males than females. It typically begins one to three weeks after an infection, mainly due to a post-streptococcal infection. The main symptom of acute nephritis is the appearance of edema, which is often an initial manifestation. Typically, this includes swelling of the eyelids in the morning, sometimes accompanied by mild swelling of the lower limbs. In addition, a urinalysis of patients might reveal blood, which can appear as either gross hematuria or microscopic hematuria. Furthermore, some patients with acute nephritis may also experience elevated blood pressure, primarily related to the edema. If managed through diuretic treatment, conditions may gradually return to normal. In severe cases of acute nephritis, symptoms can include dizziness, hypertensive encephalopathy, and even reduced urine output leading to acute kidney failure. Therefore, it is crucial to give significant attention to patients with acute nephritis and treat them actively to avoid severe complications.
What will happen if someone with IgA nephropathy stays up late?
IgA nephropathy is a very common glomerular disease in clinical settings and is one of the main causes of uremia. IgA nephropathy is most commonly seen in adolescents, particularly in males. The cause of IgA nephropathy is currently unclear, but the clinical manifestations of patients with IgA nephropathy are numerous and vary in severity. For patients with milder IgA nephropathy, it is important to maintain a healthy lifestyle, avoid staying up late, overworking, and infections. Frequently staying up late can aggravate the condition, leading to significant proteinuria and even worsening kidney function. Therefore, it is crucial for patients with IgA nephropathy to regularly monitor their urinalysis, kidney function, and blood pressure, maintain a regular lifestyle, and avoid various adverse lifestyle impacts. Of course, once the condition worsens, it is important to seek medical attention promptly and pursue active treatment.
Is allergic purpura nephritis contagious?
Kidney damage caused by allergic purpura is called allergic purpuric nephritis. The main mechanism of allergic purpuric nephritis is the deposition of immune complexes in the kidneys, causing hematuria, proteinuria, edema, and hypertension. Severe cases of purpuric nephritis may also lead to renal failure. Additionally, patients with allergic purpuric nephritis exhibit systemic symptoms such as skin purpura, abdominal pain, joint pain, and melena. Allergic purpuric nephritis usually occurs in children, and it is not contagious. Unlike viral hepatitis, tuberculosis, and dysentery, it does not spread through respiratory, digestive, or blood pathways.
IgA kidney disease symptoms
IgA nephropathy is characterized by the deposition of IgA in the glomerular mesangial regions and is a common type of glomerulonephritis. It is also a major cause of uremia. IgA nephropathy typically affects adolescents. Once diagnosed, patients primarily experience recurrent macroscopic hematuria, especially after skin infections or respiratory infections, during which blood in the urine becomes more apparent. Of course, there can also be asymptomatic hematuria and increased urinary protein. Some patients with IgA nephropathy may also experience edema, particularly in the eyelids and facial area upon waking up in the morning, and in severe cases, there may be an increase in blood pressure and a decline in kidney function. It is essential for patients with IgA nephropathy to have regular follow-ups to monitor changes in routine urine tests, kidney function, and blood pressure, and to seek active treatment if the condition worsens.
What causes acute pyelonephritis?
Acute pyelonephritis refers to an acute inflammatory disease caused by bacteria invading the renal pelvis. It is commonly seen in women of childbearing age, the elderly, individuals with weakened immune systems, and patients with urinary tract obstructions. The main clinical manifestations of acute pyelonephritis typically include frequent urination, increased urination frequency, painful urination, back pain, fever, cold stomach, and it can even present symptoms such as headache, whole body muscle soreness, nausea, and vomiting. The most common pathogen causing acute pyelonephritis is Escherichia coli, while other bacteria such as Klebsiella pneumoniae, Proteus, and Pseudomonas aeruginosa can also cause infections of acute pyelonephritis. Therefore, it is crucial to actively choose sensitive antibiotics for the treatment of acute pyelonephritis.
