Role of air pollution in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease that can affect almost every organ in the human body. The etiology and pathogenesis are unclear. Recent studies have shown that pathogenesis and development of SLE result from the interaction between various internal and external factors. Current studies suggest that air pollution may increase the risk of SLE through multiple mechanisms such as inducing immune disorders, causing epigenetic changes, and inducing oxidative stress. Air pollution has a certain relationship with pulmonary interstitial lesions, lupus nephritis, decreased reproductive function and other system damages in SLE patients, and it is related to the occurrence and clinical outcomes of SLE. Air pollution has a potential role in the occurrence and development of SLE, providing a brand-new view on the early prevention and control of SLE.
