Author Interviews, Cost of Health Care, Dermatology, JAMA / 16.08.2017 Interview with: Kyle T. Amber, MD Department of Dermatology UC Irvine Health Irvine, CA 92697-2400 What is the background for this study? What are the main findings? Response: The use of IVIg has been shown in randomized controlled trials to be safe and highly effective in the treatment of both pemphigus and bullous pemphigoid. Despite its efficacy, its cost remains a deterrent to its use. Cost studies in the United States point towards IVIg being an overall cost-saving therapy in the treatment of  Autoimmune Blistering Diseases when compared to traditional immunosuppressive treatment due to the decrease in associated infections, complications, and hospitalizations.
