[Prophylaxis and treatment of infections in elderly patients with rheumatism]

In general, the risk of serious infections increases with age, mainly explained by immunosenescence and accumulation of comorbidities. Those patients with rheumatoid arthritis who are of advanced age and require treatment with immunosuppressive agents are at particular risk to develop an infectious disease. Actual requirement and kind of treatment on the one hand, and risk of infection on the other hand, have to be considered carefully for each patient. For example, in high-risk patients, it is important to use glucocorticoids in a minimal way, i.e. in low doses and as short as possible. Vaccination, especially against influenza and pneumococci, plays an essential role in preventing infectious diseases, particularly in the elderly. Nevertheless, in cases of suspected bacterial infection, empiric antibiotic therapy should be started promptly. Due to the burden of drugs taken by patients of advanced age, the benefits and possible side effects as well as potential drug interactions have to be carefully considered. In summary, drug treatment of the elderly requires bearing in mind the complete health status of the individual patient.
