Purpura nephritis may be controlled for life without recurrence after it is well controlled, but a considerable number of patients with purpura nephritis will have recurrence, which is commonly seen in patients with recurrent allergies or immunocompromised. For the majority of patients with purpura nephritis, the disease may be controlled for life without recurrence after healing through timely treatment such as plasma exchange and vasoconstrictor antagonists. The disease is mainly to control the immune inflammatory response as the principle of treatment, but also need to inhibit the proliferative lesions of glomerular cells to reduce the recurrence rate. Some patients with purpura nephritis are more stubborn and have poorer autoimmunity, so even if they are cured, they may experience relapse under the influence of infected bacteria, viruses, parasites and other factors. The specific recurrence rate varies from person to person. Patients with purpura nephritis need to be regularly observed after the disease is under control. If skin rashes, joint pains and gastrointestinal reactions occur again, it is recommended to go to a regular hospital for timely consultation and targeted treatment under the guidance of a doctor.
