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.

Does acute nephritis easily lead to excessive internal heat?

What is referred to as "getting heated" generally refers to the appearance of herpes around the mouth. In fact, most people carry the herpes virus, which typically does not flare up under normal circumstances. However, when the body's immune system is weakened, the virus can become active. For example, factors like long-term fatigue, lack of sleep, or other illnesses can lead to the reemergence of these sores. They can also appear during acute nephritis, as this condition involves kidney abnormalities or possible symptoms like blood and protein in the urine. Some patients may also experience reduced urine output and acute kidney failure. During acute kidney failure, the immune system is often weakened, which can lead to the reappearance of herpes around the mouth, commonly known as "getting heated."

Sequelae of acute nephritis

Most cases of acute nephritis do not cause complications; generally speaking, acute nephritis is a self-healing disease that can recover on its own. Approximately three to four weeks later, the condition can gradually alleviate, with the patient’s urine protein and occult blood decreasing until they disappear and kidney function returns to normal, and the edema can also subside, so generally there won’t be any complications. However, there are a minority of patients whose conditions are prolonged and do not heal, and if the patient's condition persists for three months or even half a year without recovery, it might evolve into chronic nephritis. Also, some patients may experience severe kidney failure, heart failure, and pulmonary infections during acute nephritis, leading to severe consequences. The likelihood of these situations occurring is relatively low.

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.

How long does hematuria last in acute nephritis?

The condition of acute nephritis is generally quite severe. Patients may experience hematuria and proteinuria, with diffuse cellular proliferation in the glomeruli. However, this disease is self-limiting, and the condition can heal on its own. It is important to control the causes of acute nephritis and the complications it may cause to help patients overcome the difficulties. Afterward, the patients' hematuria and proteinuria could potentially disappear. Generally, it takes about 3 to 4 weeks for the urinalysis to turn negative, and some patients may even take up to six months to recover. If recovery takes more than six months, it is possible that the patient's acute nephritis has become chronic nephritis.

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.
