Embolic nephritis is one of the renal manifestations of renal damage in infective endocarditis, including cardiovascular interventional consultations and cardiac or non-cardiac procedures, intracardiac pressure monitoring intubation, atrioventricular shunts, high-energy nutrition, biopsies, pacemakers, arteriovenous intubation, catheters, tracheal intubation (especially in patients with burns, with reduced resistance). The bacteria that cause infective endocarditis or their products act as antigens and produce corresponding antibodies, both of which form a circulating immune complex. The site of deposition of the immune complex in the glomerulus is related to the type of bacteria and the period of infection, but depends mainly on the size and solubility of the antigen-antibody complex. The first step in embolic nephritis is to get rid of the causative factors and treat the primary disease, actively prevent and treat various infectious foci such as oral infections, skin infections, urinary tract infections and pneumonia to reduce the incidence of infective endocarditis, to adhere to prevention, to inform the public about the dangers of the disease and to advise people to stay away from drugs. For those who have intravenous drug dependence advise them to actively detoxify to reduce the incidence of cardiac infective endocarditis. Effective prevention of infective endocarditis is also the main measure to prevent its renal damage.
