Acute glomerulonephritis
Is acute nephritis contagious?
Acute nephritis is not contagious. Acute nephritis generally occurs after a patient has a bacterial inflammation of the respiratory tract, such as infections by streptococcus, staphylococcus, and other bacteria affecting the respiratory tract, urinary tract, digestive tract, or skin. This leads to a secondary inflammatory response. These inflammatory immune complexes travel through the bloodstream to the kidneys, causing an inflammatory reaction within the organ. It could also be due to the deposition of immune complexes within the glomeruli, leading to glomerular damage. This disease itself is not contagious. Although these bacteria exist as triggers, they typically do not have the capability to infect other patients. Moreover, even if they were to infect others, it would not necessarily lead to nephritis.
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.
Can people with acute nephritis eat beef?
In the acute phase of nephritis, patients are generally required to have a light diet and minimize their protein intake, with their protein intake level being about 80% of that of a normal person. They should primarily consume animal-based proteins, which should account for more than 50% of their intake. This principle is called a high-quality, low-protein diet. Therefore, overall, patients with acute nephritis can eat beef, as it is considered a high-quality protein. However, the amount ingested needs to be limited. The intake of beef should be calculated based on the patient's body weight, with every 100 grams of beef containing 20 grams of protein. The total daily protein intake for patients should be 0.6 to 0.8 grams per kilogram of body weight, including both animal and plant proteins. Patients can use the aforementioned data to calculate how much beef they can eat.
What are the symptoms of acute nephritis?
All patients with acute nephritis will have abnormalities in routine urinalysis, presenting with hematuria or proteinuria, or both concurrently. However, the severity of the condition varies. Some patients may have a large number of red blood cells in their urine, resulting in gross hematuria, tea-colored urine, light red urine, or urine resembling washed meat. Patients might also experience an increase in urine foam due to a large amount of urinary protein. Additionally, patients may develop acute renal failure, during which they might experience a decrease in urine output. However, all mentioned conditions can gradually improve over the course of three to four weeks, with increases in urine output, normalization of routine urinalysis, and resolution of edema.
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.
How to treat acute nephritis?
Acute nephritis is commonly seen in children and is a frequent type of glomerular disease in this group. Typically, one to three weeks prior to the onset, there often is a history of upper respiratory tract infection or skin infection. Subsequently, within one to three weeks, patients may experience gross hematuria and eyelid edema. In severe cases, elevated blood pressure and renal dysfunction may occur. Currently, there are no especially effective treatments for acute nephritis. However, if diagnosed properly and treated timely, the cure rate for acute nephritis is very high. Specifically, during the acute phase of acute nephritis, patients should rest in bed, follow a light diet, and adjust water intake based on urine output. Additionally, if patients with acute nephritis also have a respiratory infection, antibiotics should be administered, generally with penicillin as the first choice. Of course, if patients with acute nephritis have significant edema or markedly elevated blood pressure, it is appropriate to use diuretics and antihypertensive medications to avoid complications like hypertensive encephalopathy and heart failure. If some patients with acute nephritis also develop acute renal failure, timely dialysis treatment should be administered to improve the prognosis of acute nephritis and enhance the effectiveness of treatment.
Can acute nephritis patients eat red dates?
In cases of acute nephritis, it is recommended that patients avoid eating red dates. During the acute phase of acute nephritis, there is severe inflammatory reaction in the glomeruli of the patient, and the extensive cellular proliferation may affect the filtration barrier of the glomeruli. If the glomeruli cannot filter blood, it leads to the accumulation of metabolic waste in the body, reduced urine output, and also affects the regulation of electrolytes and acid-base balance. Therefore, patients with acute nephritis may experience kidney failure and hyperkalemia, among other issues. Red dates contain a high amount of potassium ions, making them a high-potassium food, especially dried dates, which are even richer in potassium ions. Therefore, in cases of acute nephritis, especially if the patient has renal failure, it is advised to avoid eating red dates.
Principles of Acute Nephritis Treatment
The treatment of acute nephritis mainly involves managing the complications of acute nephritis, because acute nephritis itself can potentially heal automatically. The inflammatory reaction in the glomeruli can naturally subside, and proteinuria can decrease, kidney function can recover. However, acute nephritis may cause some complications that could be life-threatening to the patient. Therefore, treatment should focus on these complications to help the patient overcome difficulties, and then wait for the acute nephritis to heal automatically. Common complications mainly include heart failure, high blood pressure, pulmonary infections, etc. Thus, if a patient experiences heart failure, diuretics or even dialysis may be needed, and if an infection occurs, a full course of antibiotics is necessary for anti-inflammatory treatment.
Is acute nephritis contagious?
Acute nephritis is not contagious. Although acute nephritis often follows a history of streptococcal infection, when such streptococci infect the human body, they can cause an immune complex reaction, which circulates through the bloodstream to the kidneys causing inflammation. Furthermore, these streptococci can have a cross-immune reaction with kidney tissue. These mechanisms together lead to diffuse proliferation of glomerular capillary cells, causing hematuria, proteinuria, and even renal failure. However, this condition generally is not contagious. Although this disease is related to streptococcal infection, these streptococci are mostly opportunistic pathogens and are unlikely to cause harm to people other than the patient, making it difficult to trigger a nephritis reaction again.
