It has long been known that there is a connection between rheumatoid factor-positive rheumatoid arthritis and cigarette smoking. Recently an important gene-environment interaction has been revealed that is carrying specific HLA-DRB1 alleles encoding the shared epitope and smoking establish a significant risk for anti-citrullinated protein antibody-positive rheumatoid arthritis. We summarize how smoking-related alteration of the cytokine balance the increased risk of infections the possibility of cross-reactivity and modifications of autoantigens by citrullination may contribute to the development of rheumatoid arthritis. Introduction It has long been known that there is a connection between seropositive rheumatoid arthritis RA and smoking. The exact underlying mechanism however has only been speculated. Cigarette smoking is one of the major environmental factors suggested to play a crucial role in the development of several diseases. Disorders affecting the great portion of the population such as atherosclerosis lung cancer or cardiovascular diseases are highly associated with tobacco consumption. More recently it has been reported that smoking is involved in the pathogenesis of certain autoimmune diseases such as RA systemic .
