Sex differences in autoimmune diseaseBarbara Volcker Center for Women and Rheumatic Disease; and Mary Kirkland Center for Lupus Research, Joan and Sanford Weill Medical College of Cornell University, Hospital for Special Surgery, 535 E 70th Street, New York,NY 10021, USALockshinM{at}hss.edu Female/male ratios of autoimmune diseases range from 10: 1 to 1: 3, with similar severity between the sexes. Men and women respond similarly to the infection and to vaccination, arguing against intrinsic sex differences in immune response. In autoimmune-like illnesses caused by environmental agents sex discrepancy is explained by differences in exposure. Endogenous hormones could cause sex discrepancy if their effect is a threshold off-on switch rather than quantitatively variable. X-inactivation and imprinting could cause sex discrepancy. Other possibilities include chronobiologic differences and pregnancy and menstruation biologies in which men differ from women.
