Join me in conversation with Dr. Andrew Franks, who is on the Lupus Foundation of America’s Medical-Scientific Advisory Council, and an advocate for educational programs that increase awareness of autoimmune diseases among the general population.
Believe it or not, autoimmune diseases are the third most common category of disease in the United States after cancer and cardiovascular disease, affecting ∼5 to 8% of the population or 14.7 to 23.5 million people. Conservative estimates indicate that ∼78% of the people affected with autoimmune diseases are women (1). Women respond to infection, vaccination, and trauma with increased antibody production, whereas inflammation is usually more severe in men resulting in an increased mortality in men and protection against infection in women. This is however a double edge sword as increased antibody response protects women from infections also increases the risk of developing an autoimmune disease.
During the COVID pandemic, patient advocacy groups have urged expansion of eligibility for the paid family and medical leave program to include individuals determined by the Centers for Disease Control and Prevention (CDC) to be at high risk for adverse complications from COVID-19.
Dr. Franks and I, along with our research teams at NYU, institution where I worked as Professor of Radiology and Orthopedic Surgery for 12 years until July 2019, were able to develop a dynamic diffusion-weighted MR imaging technique spear-headed by Dr. Eric Sigmund, physicist at the NYU Center for Biomedical Imaging (2). This technique has proven useful in diagnosing subclinical microstructural alterations of the muscle fibers in patients with amyopathic dermatomyositis.
