Polyarteritis nodosa

There are no specific known triggers to disease flares of PAN that patients can avoid. The treatment of PAN can be intensive, as can the measures needed to prevent further morbidity from treatment, but patients' adherence to management is key to optimizing outcomes. Support for patients from specialist occupational therapists, physical therapists, psychologists, rheumatology practitioners, rheumatologists, and (in the case of HBV-related PAN) gastroenterologists is needed at the outset and throughout the disease process. Patients are advised to contact their hospital team urgently if they suspect a relapse of their condition. Patients are at risk of infection, especially while being treated with high doses of corticosteroids and immunosuppressive agents, and they are advised to avoid close household contact with people who have infectious diseases, especially varicella infections and respiratory infections.
