Acute rheumatic fever kidney damage

　　Acute rheumatic fever kidney damage is an immunological damage caused by rheumatic fever, which is characterized by short-term, non-progressive, and mild pathological changes in the kidneys. Occasionally, short-term nephrotic syndrome may be observed without clear signs of kidney damage.

　　Acute rheumatic fever kidney damage often complicates with rheumatic arthritis and other diseases. Rheumatic arthritis is an allergic disease and one of the main manifestations of rheumatic fever, usually starting with acute fever and joint pain.

　　Individual patients with acute rheumatic fever kidney damage may have transient gross hematuria or mild proteinuria, which disappears after a few days. Occasionally, short-term nephrotic syndrome may be seen without clear signs of kidney damage.

　　Acute rheumatic fever kidney damage is an immunological damage with mild pathological changes caused by rheumatic fever, affecting both kidneys for a short period of time and non-progressive. To prevent acute rheumatic fever kidney damage, it is necessary to actively treat related diseases such as acute rheumatic fever and avoid bacterial infections. In daily life, appropriate exercise should be done to enhance physical fitness.

　　The diagnosis of acute rheumatic fever kidney damage mainly relies on auxiliary examinations. The specific examinations are as follows:
　　1. Urine is mild proteinuria or hematuria.
　　2. Renal function is generally normal.
　　3. Pathological changes are often segmental or mild to moderate diffuse mesangial proliferation, occasionally showing signs of acute interstitial nephritis, which are all short-term changes.

　　Attention should be paid to daily diet in acute rheumatic fever kidney damage to avoid exacerbating the condition. Specific matters to be paid attention to are as follows:
　　1. Avoid spicy and greasy foods. Spicy foods (such as chili, ginger, scallions, garlic, alcohol, etc.) and greasy foods (such as fatty meat, fried foods, etc.) are easy to generate heat and exacerbate the condition, which is not conducive to the recovery of the disease.
　　2. Avoid lack of nutrition. Due to fever and reduced intake, various nutrients are consumed more and intake less. This will make the body's resistance weaker. If nutrition is not paid attention to, it will become thinner, further weakening the resistance, and external evil can easily invade, thus aggravating the condition.
　　3. Avoid warming foods. Warming foods (such as dog meat, lamb, donkey meat, horse meat, deer meat, etc.) are easy to dry up and injure the Yin, promoting the development of the disease.
　　4. Avoid triggers. Triggers (such as rooster, pork head meat, sows' meat, leeks, etc.) can cause the recurrence of diseases after recovery or exacerbate the condition. At the same time, smoking is also not recommended.

　　Acute rheumatic fever kidney damage is a short-term, self-limiting disease that does not require special treatment and usually improves or returns to normal with the improvement of rheumatic fever. If hematuria is significant, refer to the treatment of IgA nephritis. Patients should pay attention to keeping warm, avoiding cold and dampness, and should rest in bed if the heart is involved. Physical activities and mental stimulation should be avoided until the body temperature, erythrocyte sedimentation rate, tachycardia control, or other significant changes in the electrocardiogram improve, and then gradually resume activities.
