Rheumatic diseases and allergies, the duality of the immune system

Abstract

Autoimmune rheumatic diseases are multisystemic disorders that mainly affect joints and muscles; some examples of these conditions are: rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and Sjögren's syndrome (SS). In general, autoimmune rheumatic diseases have a high prevalence worldwide and are highly disabling for those who have them. At present, one of the main limitations for the management of these diseases is that their triggering factor continues to be unknown in most cases and the knowledge of the factors associated with their exacerbation is limited. In this review, the possible link of allergies as a possible trigger for autoimmune rheumatic diseases will be explored. We will also analyze the basic and general aspects of both diseases and the development of allergic processes and hypersensitivity reactions to drugs used in the treatment of rheumatic diseases.
