The treatment of purpura nephritis varies according to the severity of the disease, usually a few thousand to ten thousand dollars. Purpura nephritis is caused by allergy to certain things, such as penicillin drugs, pollen and fish and shrimp food. When the allergy occurs, it will be manifested as skin type, abdominal type, joint type and kidney type, and when it involves the kidneys, it is called purpura nephritis. Purpura nephritis is a heavy manifestation of purpura, so it is tricky and costly to treat. Before treatment, it is necessary to complete the blood routine, double kidney ultrasound, virus-related, antinuclear antibody spectrum and other related examinations to exclude secondary causes, and then give angiotensin-converting enzyme inhibitors, glucocorticoids, calcium gluconate, vitamin C, triclabendazole, dipyridamole and other drugs to treat it. Those who are sensitive to medication may improve within two weeks. If it is not sensitive to medication, it may last longer or even be prolonged, and the cost will naturally increase. If necessary, it is also necessary to carry out renal puncture examination to clarify the type of pathology and guide the treatment.
