[Multimorbidity in elderly rheumatic patients part 2].

While diseases, such as cardiovascular diseases and osteoporosis in the elderly are categorized as comorbidities of rheumatoid arthritis, elderly rheumatic patients are often additionally affected by thyroid dysfunctions and diabetes mellitus type 2, so that the risk of multimorbidity (coexistence of at least two chronic and/or acute diseases) will increase significantly in elderly patients already suffering from systemic rheumatic diseases. Restricted cognition, adherence or compliance may additionally complicate the treatment of elderly rheumatic patients. Furthermore, the pharmacokinetics of the elderly is another challenging task. Referring to selected aspects of geriatric pharmacotherapy, the use of certain substance classes is described in this context.
