Of all inflammatory rheumatic diseases gout has the highest prevalence. Patients with intermittent acute gout attacks are usually treated by primary care physicians. However, in cases of insufficient long-term control of serum uric acid levels, complications or atypical clinical manifestations may necessitate consultation with a rheumatologist in the further course of the disease. An oligoarticular or polyarticular presentation can give rise to the initial suspicion of rheumatoid or psoriatic arthritis. In these cases a careful clinical work-up supported by laboratory and imaging investigations is necessary and synovial fluid analysis is usually required. As in other rheumatic diseases extra-articular manifestations are of utmost importance for morbidity and mortality. Gout is a complex metabolic and inflammatory disease and besides articular symptoms the renal and cardiovascular effects of hyperuricemia are particularly relevant for the overall prognosis.
Compared to other chronic inflammatory diseases, gout appears to based on a rather "simple" pathophysiology and therefore the amount of teaching time in medical school and during internship is rather limited. On the other hand, several problems in short- and long-term management still need to be solved - combined with the problem of an increased incidence in elderly people. However, there is significant advance in the knowledge of its pathophysiology including the fact that gout is more than a pure "crystal arthopathy" but rather within the spectrum of chronic inflammatory immunologic diseases. This includes cytokines such as interleukin-1 and intracellular signaling via the inflammasome. For treatment, the novel and effective xanthine oxidase inhibitor febuxostat has been added to the therapeutic armamentarium. Guidelines of EULAR and BSR support the physician in the long-term management of the numerous gout patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
