The full story should be taken, in particular with respect to:
- Duration of symptoms and signs
- Recent illness
- Recent exposure to medicines, vaccines and chemical products
- Other symptoms – for example, arthralgia, cough, numbness and paresthesia
- Detailed review of all systems
- Considering the systemic nature of many vasculitic diseases, a complete physical examination should be performed including that of the Central Nervous System.
Idiopathic (45-55%). Infection (15-20%). Inflammatory disease (15-20%) – for example, systemic lupus erythematosus, rheumatoid arthritis, Crohn’s disease and ulcerative colitis.
Drug-induced (10-15%) – for example, sulfonamides, beta-lactams, quinolones, nonsteroidal anti-inflammatory drugs (NSAIDs), oral contraceptives, anti-influenza vaccines. Chemical products such as insecticides and petroleum products.
Neoplastic (<5%) – for example, as a result of a paraproteinemia or lymphoproliferative disorder.
Classification. Several studies have been conducted to classify this group of diseases and several classifications are available today.
